coding something else, I don't remember which part were changed. Maybe somewhere around url_regex. Perhaps if <a href="http://piju.fakap.net/2008/11/08/tutorial-how-to-cache-youtube-using-squid-caching-proxy/">piju's blog</a> are still running (which is currently not), we can do a diff to compare them. Anyway, here it is. These scripts are shared and distributed as is. If you change it, feel free to let me know.

And this time, I will talk about mod_python.psp where <b>PSP</b> stands for <b>Python Server Pages</b>.<br /><br />What good about Python Server Pages for former PHP or JSP programmer is the way you can write your code where you can use the <% # your code here %> tag as you always do. But before that, you have to configure your server to enable mod_python.psp.<br /><br /><b>Pre-requisite</b><br />In order to run your site with PSP, you have to install and enable mod_python. Here is the steps if you are using Ubuntu:<br /><ol><li>Install apache2 and libapache2-mod-python and enable mod-python<br /><pre id="linuxterm">$ sudo apt-get install apache2<br />$ sudo apt-get install libapache2-mod-python<br />$ sudo a2enmod python</pre></li><li>Edit /etc/apache2/sites-enabled/000-default.

I have made some modification on the source code and then it spark me an idea to share the source code as open source too. Therefore, I clean up my messy code, make some documentation and comments so people can reuse the code. And I name it as <a href="http://code.google.com/p/hitunghari/">HitungHari</a>.<br /><br />The word <b>HitungHari</b> actually come from Malay words for counting days. Where 'Hitung' means 'Count', and 'Hari' means 'Days'. I have more ideas to develop from this piece. Perhaps, you may also have ideas too. I would be glad to hear your comments. Checkout the <a href="http://code.google.com/p/hitunghari/">Google Code site for HitungHari</a> and feel free to download, try, hack, and comment it.<br /><br /><iframe src="http://www.facebook.com/plugins/like.php?href=http%3A%2F%2Fwww.facebook.com%2Fpages%2FCoders-Talk%2F138805102822113&layout=standard&show_faces=false&width=640&action=like&font=tahoma&colorscheme=light&height=35" scrolling="no" frameborder="0" style="border:none; overflow:hidden; width:640px; height:35px;" allowTransparency="true"></iframe><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-5432157279446514639?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com1tag:blogger.com,1999:blog-3928190665450830956.post-65670376808531228932011-04-19T12:21:00.005+08:002011-04-25T19:06:31.451+08:00MOSC 2011 Countdown Banner<div class="separator" style="clear: both; text-align: center;"><a href="http://coderstalk.blogspot.com/2011/04/mosc-2011-countdown-banner.html" imageanchor="1"><img border="0" src="http://3.bp.blogspot.com/-PRcz1mT6i14/Ta0MuNXTL3I/AAAAAAAACSU/kuDdjSCW4lw/s600/mosc-countdown-inkscape-apogee.png" width="520" /></a></div><br />I'm just having fun with PHP GD and Inkscape.

Drop a little amount of it to my text book while my teacher is teaching something else, and see the pages being eaten by those acids. Just because I'm getting bored in class. That was one case of myself. How about you? Have you ever misuse your science lab chemicals? Today, I found other way for student to learn about chemical reaction without ever use the actual chemical.<br /><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://coderstalk.blogspot.com" imageanchor="1" style="margin-left:1em; margin-right:1em"><img border="0" width="520" src="http://3.bp.blogspot.com/-jVzgfwQCsT0/TaVAHZmal-I/AAAAAAAACR0/j_d7kq2lthA/s600/_D7H9870.JPG" /></a></div><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://coderstalk.blogspot.com" imageanchor="1" style="margin-left:1em; margin-right:1em"><img border="0" width="520" src="http://3.bp.blogspot.com/-9tZ6bckd9Fo/TaVANhzpY4I/AAAAAAAACR8/gl83m6ogsWA/s600/_D7H9607.JPG" /></a></div><br />At Museum of Science and Industry in Chicago, you can experiment and create a chemical reaction using their interactive exhibit in the Science Storms wing. This interactive exhibit is called Create a Chemical Reaction. Using specially-tagged pucks, visitors can grab atoms from the periodic table and combine them to cause chemical reactions.<br /><br /><iframe title="YouTube video player" width="525" height="390" src="http://www.youtube.com/embed/aGsmFLCcDSw" frameborder="0" allowfullscreen></iframe><br /><br />The "Create a Chemical Reaction" interactive exhibit is powered by <a href="http://www.pattenstudio.com/projects/sensetable/" target="_blank">Sensetable</a> platform from Patten Studio. The Sensetable concept and initial prototypes were developed by the Tangible Media Group at the MIT Media Lab. James Patten, Hiroshi Ishii, Jim Hines and Gian Pangaro are the people who invent this amazing Sensetable, A Wireless Object Tracking Platform for Tangible User Interfaces. Iwish I could play with it.

In my case, it get rebooted when I'm running few programs that continuously reading the input from the DIO. As this system is running linux, we can use swap memory instead of physical RAM. So, to solve this problem, we can create swap file on this ts-7260. Here is how to add swapfile on ts-7260 board running the default debian Sarge on ts11 kernel 2.4 SD card boot linux.<br /><span class="fullpost"><br />Let's check the free memory...<br /><pre id="linuxterm"><span class="fullpost">root@ts7000:root# free -m<br />total used free shared buffers cached<br />Mem: 28 26 1 0 1 18<br />-/+ buffers/cache: 6 21<br />Swap: 0 0 0<br /></span></pre><br />From the above result, you can see the total memory is 28 and we have 0 on swap. Now, we have to create the swapfile using this command:<br /><br /><pre id="linuxterm">root@ts7000:root# dd if=/dev/zero of=/swapfile bs=1024 count=98304<br />98304+0 records in<br />98304+0 records out<br />100663296 bytes transferred in 75.990000 seconds (1324691 bytes/sec)<br />root@ts7000:root# mkswap -L swapfile /swapfile<br />Setting up swapspace version 1, size = 100659 kB<br />LABEL=swapfile, UUID=6c0cf1ae-d174-48c6-99ac-cc9f2a35ba21<br />root@ts7000:root# swapon /swapfile <br /></pre><br />Check free memory again<br /><br /><pre id="linuxterm">root@ts7000:root# free -m<br />total used free shared buffers cached<br />Mem: 28 26 1 0 1 18<br />-/+ buffers/cache: 6 21<br />Swap: 95 0 95<br />root@ts7000:root# <br /></pre><br />Now, you should see there is 95MB swap. And to make it permanent, add this entry on /etc/fstab<br /><br /><pre id="linuxterm">/swapfile none swap sw 0 0<br /></pre><br />as the command goes...<br /><br /><pre id="linuxterm">root@ts7000:root# cat /etc/fstab<br />proc /proc proc defaults 0 0<br />none /dev/pts devpts gid=5,mode=620 0 0<br />/dev/sdcard0/disc0/part3 / ext2 defaults,noatime,async 1 1 <br />root@ts7000:root# vi /etc/fstab<br />root@ts7000:root# cat /etc/fstab<br />proc /proc proc defaults 0 0<br />none /dev/pts devpts gid=5,mode=620 0 0<br />/dev/sdcard0/disc0/part3 / ext2 defaults,noatime,async 1 1 <br />/swapfile none swap sw 0 0<br /></pre><br />I hope this can help you with your ts-7260 SBC.

Just grab your tools and start small. This time, I just wanna show you how to start C programming in linux. You can use any Linux distro. However, if you are beginner, just follow me using Ubuntu Linux.<br /><br /><b>1. Install the required packages.</b><br />First of all, you have to make sure that you have C compiler to compile your code. In linux, we use "gcc - GNU project C and C++ compiler".<br /><br />In Debian, Ubuntu and it's family distro, all the basic programming tools for C programming can be found in build-essential package. Use this command to install this package:<br /><br /><pre id="linuxterm">$ sudo apt-get install build-essential </pre><br /><b>2. Write your first program</b><br />Now, after installing the required package, we can start coding our first program. As usual, you may start with a "Hello World" program.<br /><br /><b>Create new project directory</b><br />Under your home directory, you may start creating your project directory to begin with. In this example, I'm calling it as myhello:<br /><br /><pre id="linuxterm">$ mkdir myhello</pre><br />Then, get into our project directory:<br /><br /><pre id="linuxterm">$ cd myhello</pre><br />Now, create our hello.c file. You may follow this example "hello world" code or be imaginative to modified it as you like. Experiments to see what is possible to modify in this code:<br /><pre style="border: 1px inset; height: 100px; margin: 0px; overflow: auto; padding: 3px; text-align: left; width: 98%;"><span class="codestyle_9">#include </span><span class="codestyle_6"><stdio.h></span><br /><br /><span class="codestyle_5">int </span><span class="codestyle_11">main</span><span class="codestyle_10">() {</span><br /><br /> <span class="codestyle_11">printf</span><span class="codestyle_10">(</span><span class="codestyle_6">"Hello My friend, Let's do C programming\n"</span><span class="codestyle_10">);</span><br /><span class="codestyle_10">}</span><br /></pre><br /><b>3. Compile your program.</b><br />To compile your first linux C program, launch your terminal and go to current directory where you put your hello.c code. Then, run this command:<br /><pre id="linuxterm">$ gcc hello.c -o hello</pre><br />After that, you will have an executable file called hello in this directory. Congratulations! you have created your first C program in linux. You can now, execute this program using this command:<br /><pre id="linuxterm">$ ./hello</pre><br /><div class="separator" style="clear: both; text-align: center;"><a href="http://3.bp.blogspot.com/_QmenDvyMjlk/TBhgHjxOJTI/AAAAAAAACFs/vh6yS1te4u0/s1600/myhello.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" height="282" src="http://3.bp.blogspot.com/_QmenDvyMjlk/TBhgHjxOJTI/AAAAAAAACFs/vh6yS1te4u0/s400/myhello.png" width="400" /></a></div>The output will be printed on your screen. You can add more stuff and experiments. Until next time, I hope you enjoy this.

Although the word is not an acronym, some companies implementing the process have been known to spell it with capital letters as SCRUM. Maybe because Ken Schwaber capitalized SCRUM in the title of his early papers about this methodology.<br /><br />Although Scrum was intended for management of software development projects, it can be used to run software maintenance teams, or as a general project/program management approach.<br /><br />A number of roles are defined in Scrum. All roles fall into two distinct groups — pigs and chickens — based on the nature of their involvement in the development process. These groups get their names from a joke about a pig and a chicken opening a restaurant<br /><br />There are several variants as to how the Chicken and the Pig meet and the level of the relationship between the two.<br /><br />However, in every variant, the Chicken suggests that the two involve themselves in a scheme involving ham (or bacon) and eggs (some suggest a breakfast, others suggest a restaurant). In reply, the Pig always notes that, for the Chicken, only a contribution is required (as a chicken can simply lay an egg and then resume normal activities), while for the Pig a "total commitment" (or total sacrifice) is needed (as in order to make ham or bacon, the pig must be slaughtered).<br /><br /><a href="http://www.implementingscrum.com/2008/07/25/welcome-to-a-time-machine-future-and-past-combine-here/" target="_blank"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 400px; height: 141px;" src="http://4.bp.blogspot.com/_QmenDvyMjlk/S4HvSv1qE_I/AAAAAAAACA8/o5xlgrJeKSw/s400/060911-scrumtoon.jpg" border="0" alt=""id="BLOGGER_PHOTO_ID_5440892930198475762" /></a><br />So the “pigs” are committed to building software regularly and frequently, while everyone else is a “chicken”—interested in the project but really indifferent because if it fails they’re not the pigs—that is, they weren’t the ones that committed to doing it. The needs, desires, ideas and influences of the chicken roles are taken into account, but are not in any way allowed to affect, distort or get in the way of the actual Scrum project.<br /><br /><span style="font-weight:bold;font-size:23px">“Pig” roles</span><br /><br />The Pigs are the ones committed to the project in the Scrum process—they are the ones with “their bacon on the line” and performing the actual work of the project.<br /><br /><span style="font-weight:bold;">Scrum Master (or Facilitator)</span><br />Scrum is facilitated by a Scrum Master, whose primary job is to remove impediments to the ability of the team to deliver the sprint goal. The Scrum Master is not the leader of the team (as the team is self-organizing) but acts as a buffer between the team and any distracting influences. The Scrum Master ensures that the Scrum process is used as intended. The Scrum Master is the enforcer of rules. A key part of the Scrum Master’s role is to protect the team and keep them focused on the tasks in hand.<br /><br /><span style="font-weight:bold;">Team</span><br />The team has the responsibility to deliver the product. A team is typically made up of 5–9 people with cross-functional skills who do the actual work (design, develop, test, technical communication, etc.).<br /><br /><span style="font-weight:bold;">Product Owner</span><br />The Product Owner represents the voice of the customer. He/she ensures that the Scrum Team works with the “right things” from a business perspective. The Product Owner writes customer-centric items (typically user stories), prioritizes them and then places them in the product backlog. A Product Owner can be a member of the Scrum Team but cannot be a ScrumMaster.<br />According to original Scrum, Product Owner is in a "pig" role. However, if the Product Owner does not have involvement regularly, he/she may be considered as a "chicken" .<br /><br /><span style="font-weight:bold;font-size:23px;">“Chicken” roles</span><br /><br />Chicken roles are not part of the actual Scrum process, but must be taken into account. They are people for whom the software is being built.<br /><br /><span style="font-weight:bold;">Stakeholders (customers, vendors)</span><br />These are the people who enable the project and for whom the project will produce the agreed-upon benefit[s], which justify its production. They are only directly involved in the process during the sprint reviews.<br /><br /><span style="font-weight:bold;">Managers</span><br />People who will set up the environment for the product development organizations.<br /><br /><a href="http://www.implementingscrum.com/2006/12/19/go-directly-to-jail-do-not-pass-go/" target="_blank"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 400px; height: 141px;" src="http://1.bp.blogspot.com/_QmenDvyMjlk/S4H2poCnfHI/AAAAAAAACBE/0QEDe0y3lPw/s400/061218-scrumtoon.jpg" border="0" alt=""id="BLOGGER_PHOTO_ID_5440901019823733874" /></a><br />That's all for now...

It is included in libnotify-bin package, which is a library that sends desktop notifications to a notification daemon, as defined in the Desktop Notifications spec. These notifications can be used to inform the user about an event or display some form of information without getting in the user's way.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_QmenDvyMjlk/S3erwGAXAVI/AAAAAAAACAk/TWHbI8hUkKI/s1600-h/install-libnotify-send.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 400px; height: 258px;" src="http://1.bp.blogspot.com/_QmenDvyMjlk/S3erwGAXAVI/AAAAAAAACAk/TWHbI8hUkKI/s400/install-libnotify-send.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5438003917807354194" /></a><br />You can install it using <span style="font-weight:bold;">Synaptic Package Manager</span> by searching for libnotify-bin package and install it. Or you can install it via terminal using this command:<br /><br /><pre id="linuxterm">apogee@apogee-ubuntu:~$ sudo apt-get install libnotify-bin<br /></pre><br />And then, you can use the notify-send command as described in my previous post about <a href="http://coderstalk.blogspot.com/2010/02/custom-gnome-notification-for-your-apps.html">Custom Gnome Notification for your apps</a>.

In my case, if I write the SD cards for my ts-7260, I would leave it and do other stuff.<br /><br />Since it is easy to get distracted with so many stuff on the internet, I sometimes forget to get back to check the dd terminal. This could waste my time because the process have stopped for quite long time where I should write another card instead just right after the first card finished.<br /><br />Therefore, I use notify-send from <a href="http://coderstalk.blogspot.com/2010/02/how-to-install-notify-send-in-ubuntu.html">libnotify-bin package</a> to notify me about my process while I'm free to check my mail, reading, surfing and so on. Here is the screenshot of my gnome notification when it is ready.<br /><div class="separator" style="clear: both; text-align: center;"><a href="http://2.bp.blogspot.com/_QmenDvyMjlk/S3Un4BzKx1I/AAAAAAAACAA/B00DXGMA7Qc/s1600-h/custom-gnome-notification.png" imageanchor="1" style="margin-left: 1em; margin-right: 1em;"><img border="0" src="http://2.bp.blogspot.com/_QmenDvyMjlk/S3Un4BzKx1I/AAAAAAAACAA/B00DXGMA7Qc/s400/custom-gnome-notification.png"/></a></div><br />It can be done with one line of command like this: <span class="fullpost"><br /><br /><pre dir="ltr" style="border: 1px inset; height: 100px; margin: 0px; overflow: auto; padding: 3px; text-align: left; width: 98%;">notify-send -i /usr/share/icons/Human/scalable/devices/media-flash.svg \<br /> -h int:x:$(xrandr -q|grep '*' | sed -e 's/x.*//' -e 's/\ //g') \<br /> -h int:y:10 -u normal -t 10000 "Copy SD card from dd Image" \<br /> "dd image to /dev/sdd finished"'!' ; mplayer /usr/share/sounds/purple/receive.wav <br /></pre><br />However, the above command is long and I wouldn't dare to type this command every time I will write new SD card.

And delete the dd file.<br /><br />However, to use the tar.gz, we don't have to extract the file because we can only use a single command like this:<br /><br /><pre id="linuxterm"># tar Ozxf sd1gb.dd.tar.gz | dd of=/dev/sdd</pre><br /><br />That's all for today... <img class='inline' src='http://coderstalk.googlepages.com/sengih.gif'/> see u later!<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-2320989547986140664?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com0tag:blogger.com,1999:blog-3928190665450830956.post-76971714440089597552009-11-14T10:02:00.012+08:002009-11-14T12:40:46.414+08:00How to Create Hyperlink on Blogger HeaderToday, I got this question in comment of my previous tutorial on <a href="http://coderstalk.blogspot.com/2008/04/how-to-create-hyperlink-on-blogger-post.html" target="_blank">How to Create Hyperlink on Blogger Post</a>.<br /><br /><a style="font-weight: bold;" href="http://coderstalk.blogspot.com/2008/04/how-to-create-hyperlink-on-blogger-post.html#comment-5292197939025391231">Barbara Fowlds L.Ac.</a><span style="font-weight: bold;">:</span> <span style="color: rgb(102, 51, 51); font-weight: bold;">"Can I put a hyperlink in my header of my blogspot blog and if so how?"</span><br /><br />My answer is Yes you can. And here's how to do it in the simplest newbie way.<br /><br />Before that, I assume you may wanted to add this hyperlink on your Blogger Header Description because maybe you want to invite your visitor to your business website or any other sites you have. For example, I may like to invite my blog reader to read my art blog at http://artofapogee.blogspot.com and my blog description says something like this:<br /><br /><blockquote>Feel free to visit <span style="color: rgb(51, 51, 255);">Art Of ApOgEE Blog</span> to see my arts and order some graphic design books</blockquote><br />And now we wanna link that blue "Art Of ApOgEE Blog" to <code>http://artofapogee.blogspot.com</code><br /><br />This is the simplest way. You just have to copy paste and no coding <img class="inline" src="http://coderstalk.googlepages.com/tongue.gif" />. Here's the step:<br /><br /><ol><li>Open up New Post on you blogger, select Edit Html and type the words there:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_QmenDvyMjlk/Sv4nAe9RZiI/AAAAAAAAB5E/Qy1EznoNQPQ/s1600-h/new-post.png"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 400px; height: 297px;" src="http://3.bp.blogspot.com/_QmenDvyMjlk/Sv4nAe9RZiI/AAAAAAAAB5E/Qy1EznoNQPQ/s400/new-post.png" alt="" id="BLOGGER_PHOTO_ID_5403799492154713634" border="0" /></a><br /></li><li>Select the text we want to link and create the link:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_QmenDvyMjlk/Sv4n2E02jbI/AAAAAAAAB5M/nvzGREkxtTc/s1600-h/create-link.png"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 400px; height: 311px;" src="http://3.bp.blogspot.com/_QmenDvyMjlk/Sv4n2E02jbI/AAAAAAAAB5M/nvzGREkxtTc/s400/create-link.png" alt="" id="BLOGGER_PHOTO_ID_5403800412853013938" border="0" /></a> Just follow the same way like we did in <a href="http://coderstalk.blogspot.com/2008/04/how-to-create-hyperlink-on-blogger-post.html" target="_blank">How to Create Hyperlink on Blogger Post</a>.<br /><br /></li><li>Select all text and copy:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_QmenDvyMjlk/Sv4oiU0_zFI/AAAAAAAAB5U/rddFUbTsr_0/s1600-h/select-all-copy.png"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 400px; height: 313px;" src="http://1.bp.blogspot.com/_QmenDvyMjlk/Sv4oiU0_zFI/AAAAAAAAB5U/rddFUbTsr_0/s400/select-all-copy.png" alt="" id="BLOGGER_PHOTO_ID_5403801173062831186" border="0" /></a><br /></li><li>Open the Layout tab and Edit your header:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_QmenDvyMjlk/Sv4qsXsFMZI/AAAAAAAAB5c/NUC-mw1eFSk/s1600-h/edit-header.png"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 400px; height: 167px;" src="http://3.bp.blogspot.com/_QmenDvyMjlk/Sv4qsXsFMZI/AAAAAAAAB5c/NUC-mw1eFSk/s400/edit-header.png" alt="" id="BLOGGER_PHOTO_ID_5403803544652689810" border="0" /></a><br /></li><li>Paste the copied text to your Blog Description and Save:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_QmenDvyMjlk/Sv4rUS_LTKI/AAAAAAAAB5k/5TgvkeB4Iow/s1600-h/blog-description.png"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer; width: 371px; height: 400px;" src="http://1.bp.blogspot.com/_QmenDvyMjlk/Sv4rUS_LTKI/AAAAAAAAB5k/5TgvkeB4Iow/s400/blog-description.png" alt="" id="BLOGGER_PHOTO_ID_5403804230585371810" border="0" /></a><br /></li></ol><br />That's all, now you have the link on your Blogger Header Description.

However, you may wondering where to start. So here again, I'm going to share with you. How to begin Lisp Programming, "the programmable programming language".<br /><br />As, I'm using Ubuntu here, this example is shown step by step on Ubuntu. <br /><br />In order to start playing with Lisp on your ubuntu, you need to install CMUCL. CMUCL is a free implementation of Common Lisp which was originally developed at Carnegie Mellon University. To install CMUCL package, just run this command on your Ubuntu terminal:<br /><pre id="linuxterm">$ sudo apt-get install cmucl</pre><br />Next, we are going to feel the environment. Open up your terminal and type:<br /><br /><pre id="linuxterm">$ lisp</pre><br />You will be greeted by CMU Common Lisp with it version and loaded subsystem. In my case, I see like this.<br /><br /><pre id="linuxterm">apogee@apogee-ubuntu:~$ lisp<br />CMU Common Lisp CVS release-19a 19a-release-20040728 + minimal debian patches, running on apogee-ubuntu<br />With core: /usr/lib/cmucl/lisp.core<br />Dumped on: Fri, 2009-11-13 09:05:47+08:00 on apogee-ubuntu<br />For support see http://www.cons.org/cmucl/support.html Send bug reports to the debian BTS.<br />or to pvaneynd@debian.org<br />type (help) for help, (quit) to exit, and (demo) to see the demos<br /><br />Loaded subsystems:<br /> Python 1.1, target Intel x86<br /> CLOS based on Gerd's PCL 2004/04/14 03:32:47<br />* <br /></pre><br />As you can see the loaded subsystem is Python 1.1. This is not the Python as in <a href="http://coderstalk.blogspot.com/search/label/python">Python Programming</a>. Don't get confused. It is a native code compiler named "Python". If Common Lisp source code has been written with appropriate declarations and is organized with speed in mind, the Python compiler generates code that is almost free from overhead compared to code compiled from languages like C++. Some inefficiencies such as function call interfaces and lack of pointer-free arrays of user-defined data types are dictated by the Common Lisp standard and still need to be worked around (e.g. by inlining more and using macros to build constructs that look like user-defined structures but are actually accessing fields in preallocated specialized arrays). The Python compiler also features powerful type inferences, helping the programmer in writing overhead-free code by either inferring types automatically or issuing hints about missed optimization opportunities. <br /><br />Before doing anything else, you have to know how to exit from this environment. To exit from this lisp terminal, you can simply type <span style="font-weight:bold;">(quit)</span> and press enter.<br /><br /><pre id="linuxterm">apogee@apogee-ubuntu:~$ lisp<br />CMU Common Lisp CVS release-19a 19a-release-20040728 + minimal debian patches, running on apogee-ubuntu<br />With core: /usr/lib/cmucl/lisp.core<br />Dumped on: Fri, 2009-11-13 09:05:47+08:00 on apogee-ubuntu<br />For support see http://www.cons.org/cmucl/support.html Send bug reports to the debian BTS.<br />or to pvaneynd@debian.org<br />type (help) for help, (quit) to exit, and (demo) to see the demos<br /><br />Loaded subsystems:<br /> Python 1.1, target Intel x86<br /> CLOS based on Gerd's PCL 2004/04/14 03:32:47<br />* (quit)<br />apogee@apogee-ubuntu:~$ <br /></pre><br />Now you know how to start and end the CMU Common Lisp. We can start playing with codes. Here is some example:<br /><br />1. Adding Numbers:<br /><br /><pre id="linuxterm">* (+ 200 800 300 700 19 10)<br /><br />2029<br />* <br /></pre><br />Notice my code started with '(' and end with ')'. <br /><br />2. Subtract Numbers:<br /><br /><pre id="linuxterm">* (* 12 2 3)<br /><br />72<br /></pre><br /><br />3. Or even Adding and Subtract:<br /><br /><pre id="linuxterm">* (+ (* 12 2 3) 1)<br /><br />73<br /></pre><br /><br />There you go.

However, I can't escape from using it because there are instruments which I use that can only communicate with it's own proprietary windows program. <br /><br /><br />Love it or not, I still need these proprietary programs to run in the windows box on site because they don't have linux version of it nor even going to have it.<br /><br /><br />Leaving the windows box like that.

And what make me more interested about it was, getting to know the <span style="font-weight:bold;">Android</span>, a new <span style="font-weight:bold;">open source operating system and software platform for mobile phones</span>. The Android is developed by Google, and later the Open Handset Alliance based on <span style="font-weight:bold;"><a href="http://coderstalk.blogspot.com/search/label/linux">Linux kernel</a></span>. Google has made most of the Android platform available under the Apache free-software and open source license. <br /><br />The <span style="font-weight:bold;">Open Handset Alliance (OHA)</span> is a business alliance of 48 firms including Google, HTC, Intel, Motorola, Qualcomm, Samsung, LG, T-Mobile, NVIDIA, Sony Ericsson, ARM, AKM Semiconductor Inc, ASUSTek COmputer Inc, Atheros Communications, Borqs, Ericsson, Garmin International Inc, Wind River Systems, Huawei Technologies, Omron Software Co Ltd, Softbank Monile Corporation, Teleca AB, Toshiba Corporation and Vodafone that came together to develop open standards for mobile devices. The Android platform was announced on 5 November 2007 <span class="fullpost"> with the founding of the Open Handset Alliance. <br /><br />Now, mobile phone application developers are able to write <span style="font-weight:bold;">managed code</span> in the <span style="font-weight:bold;">Java language</span>, controlling the mobile device with Android via <span style="font-weight:bold;">Google-developed Java libraries</span>. If you are good in C or other <span style="font-weight:bold;">programming</span> languages, your applications written in C and other languages can be compiled to ARM native code and run. However, the other development path isn't officially supported by Google. <br /><br />And, here is a video from <span style="font-weight:bold;">Android</span> developer to get you more excited with this Android <img class='inline' src='http://coderstalk.googlepages.com/tongue.gif'/> :<br /><br /><center><object width="425" height="344"><param name="movie" value="http://www.youtube.com/v/1FJHYqE0RDg&hl=en&fs=1"></param><param name="allowFullScreen" value="true"></param><param name="allowscriptaccess" value="always"></param><embed src="http://www.youtube.com/v/1FJHYqE0RDg&hl=en&fs=1" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="425" height="344"></embed></object></center><br /><br />Isn't it a WoooOOoW for you coders?... Let's get up, <a href="http://www.android.com/">grab the SDK</a> and develop great apps on Android. I would love to hear one of us entitled for those <span style="font-weight:bold;">TEN MILLION U.S. DOLLARS</span> for creating a great, useful, free and open source software on <span style="font-weight:bold;">Android platform</span>. <img class='inline' src='http://coderstalk.googlepages.com/sengih.gif'/><br /><br /><quote><span style="font-style:italic;">p/s: For all my Chinese friends and readers, I would like to wish you all a very Happy and Prosperous Chinese New Year!!

But, if you wanna skip it, the first episode is the introduction of a <span style="font-weight:bold;">brilliant programmer or hacker</span> named <span style="font-weight:bold;">Akira Shirase</span>. <br /><br />In that episode, there was a <span style="font-weight:bold;">hacking attempt</span> on U.S. shipping company which reroutes a package to an <span style="font-weight:bold;">Asian Hacker</span>. While on the other side, BPS or <span style="font-weight:bold;">Battle Programmer Shirase</span> is recruited by Akizuki, an employee from Abin Electronics. BPS accepted Akira's recruitment after seeing the <span style="font-weight:bold;">discontinued X68 series doujinshi SCSI card</span> by Abin Electronics which was made at Iwasawa plant. Apart from that, there is another story of Misao-chan who somehow have an unknown relationship with Shirase. Now, let's watch this <span style="font-weight:bold;">Episode 2 of Battle Programmer Shirase</span>... <br /><br /><center><object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/7SOlmlxGC8w&hl=en"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/7SOlmlxGC8w&hl=en" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object></center><br /><br />Hmm.. hope you like it.

Ubuntu releases are issued every six months and include the latest versions of popular open source software applications.<br /><br /><blockquote style="color: rgb(255, 102, 0);">"The Warrior Rabbit is our talisman as we move into a year where we can reasonably expect Ubuntu to ship on several million devices, to consumers who can reasonably expect the software experience to be comparable to those of the traditional big OSV's—Microsoft and Apple," he wrote in a mailing list post. "The bar is set very high, and we have been given the opportunity to leap over it. It's a once-in-a-lifetime chance to shine, and we want to make sure that the very best thinking across the whole open source ecosystem is reflected in Ubuntu, because many people will judge free software as a whole by what we do."</blockquote><br /><br />A big focus of the 9.04 release will be improving boot time and general performance. Shuttleworth also says that the developers also aim to bring tighter web integration to the desktop. Ubuntu 9.04 will be like a Jackalope, he claims, because it will be lightning fast and will converge desktop and web technologies to create a hybrid software experience.<br /><br /><blockquote style="color: rgb(255, 102, 0);">"There are some specific goals that we need to meet in Jaunty. One of them is boot time. We want Ubuntu to boot as fast as possible—both in the standard case, and especially when it is being tailored to a specific device," he wrote. "Another goal is the blurring of web services and desktop applications."</blockquote><br /><div style="float: right; text-align: center; margin-left: 15px; margin-bottom: 15px;"><a href="http://www.flickr.com/photos/7768604@N05/2635060236/" title="jackalope sighting by evie_coates"><img src="http://farm4.static.flickr.com/3111/2635060236_5e05cb9fb6_t.jpg" alt="jackalope sighting by evie_coates" /></a><br /></div><br clear="all" />Ubuntu has achieved unprecedented popularity in the desktop Linux ecosystem and is rapidly moving into the general consumer market.

For instance, while I'm working with TS-7260 board from Technologic Systems, the COM3 serial interface have only 3 pin which is RX, TX and GND. So, in order to make my Wavecom GSM/GPRS/EDGE modem working, I have to create my own cable pinout to connect the 15 pin connector on the Wavecom Modem to the 3 pin RS-232 serial interface on the board. <br /><br />Before creating the cable, I did some search and find this cable pinout from Wavecom GSM Modem manual.<br /><pre>Pin Description<br />1 DCD (Data Carrier Detect)<br />2 TXD (Transmit Data)<br />3 Reserved<br />4 MICROPHONE (+)<br />5 MICROPHONE (-)<br />6 RXD (Receive Data)<br />7 DSR (Data Set Ready)<br />8 DTR (Data Terminal Ready)<br />9 GND(Signal Ground)<br />10 SPEAKER (+)<br />11 CTS (Clear To Send)<br />12 RTS (Request To Send)<br />13 RI (Ring Indicator)<br />14 RESET<br />15 SPEAKER (-)<br /></pre>and the pinout from TS-7260 Board manual:<br /><quote><br /><span style="font-weight: bold;">5.6 COM3 Header</span><br />In the default TS-7260 configuration (OP-2TTLCOM not selected), the COM3 port has RS-232 signal levels, utilizes RTS and CTS signals and is accessible on a 10-pin header labeled COM3:<br /></quote><br /><pre>Table: TS-7260 COM3 Serial Port Header Pin Out<br /><br /> NC RTS CTS NC NC<br />|-----|-----|-----|-----|-----|<br />| 6 | 7 | 8 | 9 | 10 |<br />|-----|-----|-----|-----|-----|<br />| 1 | 2 | 3 | 4 | 5 |<br />|-----|-----|-----|-----|-----|<br /> NC RXD TXD NC GND<br /></pre>The COM3 serial port is implemented at address 0x12400000. It has a 5-byte receive FIFO and a 1-byte transmit FIFO. A TS-Kernel serial driver, "tsuart" is available which allows manipulation of this hardware in Linux using the device node /dev/ttyTS0.

However, we cannot find this type of modem anymore in stock from our supplier. So, they suggest us to use Wavecom Fastrack Supreme 20 and then the weird thing happen.<br /><br />By default, the Modem is working fine with my computer but somehow didn't work on my SBC. The modem didn't reply to any command I send. I did check the baud rate, cable and pinout. It is exactly the same pinout and the default baudrate is 112500. So, what is going to be wrong here?<br /><br />After a day of searching, I found that the default setting for DTE-DCE local flow control of this modem is set to 2,2. you can check it by sending this command to your wavecom modem:<br /><code><br />AT+IFC?<CR><br /></code><br /><span style="font-size: 80%;">* please note that <CR> is just a simbol for carriage return character.</span><br />and my modem reply like this:<br /><code><br />AT+IFC=2,2<br /></code><br />Here is the setting table for the DTE-DCE local flow control +IFC:<br /><br />This command is used to control the operation of local flow control between the DTE and DCE.<br /><br />AT+IFC=<DCE_by_DTE>,<DTE_by_DCE><br /><br />*< DCE_by_DTE ><br /><center><br /><table border="1" cellpadding="3" cellspacing="0" style="border: 1px solid gray; padding: 3px; width: 90%;"><tbody><tr><th style="text-align: left; width: 10%;">code</th><th style="text-align: left;">description</th></tr><tr><td>0</td><td>none</td></tr><tr><td>1</td><td>Xon/Xoff local circuit 103</td></tr><tr><td>2</td><td>RTS</td></tr><tr><td>3</td><td>Xon/Xoff global on circuit 103</td></tr></tbody></table><br /></center><br /><br />*< DTE_by_DCE ><br /><center><br /><table style="border: 1px solid gray; width: 90%;"><tbody><tr><th style="text-align: left; width: 10%;">code</th><th style="text-align: left;">description</th></tr><tr><td>0</td><td>none</td></tr><tr><td>1</td><td>Xon/Xoff circuit 104</td></tr><tr><td>2</td><td>CTS</td></tr></tbody></table><br /></center><br /><br />So, in order to fix it, I connect the modem to my computer and use minicom to send this command to the modem:<br /><pre>AT+IFC=0,0<CR><br />AT&W<CR><br /></pre><br />then plug it back to the SBC with the 3 pin cable. and it should works like charm again. <img class="inline" src="http://coderstalk.googlepages.com/tongue.gif" /><br /></span><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-3984771265220082264?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com4tag:blogger.com,1999:blog-3928190665450830956.post-2010482979758153912008-11-12T08:00:00.001+08:002008-11-12T10:24:50.679+08:00Howto do command sequence in linux with conditional checkOne of the cool things you can do in your CLI (Command Line Interface) or so called Terminal console is triggering one line of multi command sequence with conditional check. I'm always using this trick when I don't wanna wait for the first command which takes some minutes to finish to trigger the next command. Some people wrote a bash script file to do it but today i wanna show you how to do it in one single line of command. One of my common use of this trick is to trigger a loud song or alert after my dd command (which takes about 15 minutes) to copy a 2GB image to my SD cards.<br /><br />So, while waiting for these command to finish, I can do something else... Like playing Gangster Battle on Facebook <a href='http://coderstalk.blogspot.com'><img class='inline' src='http://coderstalk.googlepages.com/tongue.gif'/></a> or chatting on the IRC (wave me @ irc.freenode.net on #ubuntu-my) <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_QmenDvyMjlk/SRo3NSI7XNI/AAAAAAAAA74/JBtnNp1d8iI/s1600-h/ddfinish.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;width: 400px; height: 191px;" src="http://1.bp.blogspot.com/_QmenDvyMjlk/SRo3NSI7XNI/AAAAAAAAA74/JBtnNp1d8iI/s400/ddfinish.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5267583415510326482" /></a><br /><br />Here's the howto:<br /><br /><span style="font-size:113%;font-weight:bold;">Executing two or more commands in sequence</span><br /><br />To execute two or more commands in sequence regardless of the failure/success of the previous command, you can use the semi colon ";" in between of your commands. For example:<br /><code><br />$ mycommand1 ; mycommand2<br /></code><br /><br />In this example, <span style="font-weight:bold;">mycommand2</span> will be executed after <span style="font-weight:bold;">mycommand1</span> have been accomplished.<br /><br /><br /><span style="font-size:113%;font-weight:bold;">Execute the next command only if the first command fails</span><br /><br />To execute the next command in condition of when the first command fails, you can use logical OR operator which is double pipes "||". I'm not sure what you call them but here's the example:<br /><code><br />$ mycommand1 || mycommand2<br /></code><br /><br /><span style="font-weight:bold;">mycommand2</span> in this example will only be executed if <span style="font-weight:bold;">mycommand1</span> failed.<br /><br /><br /><span style="font-size:113%;font-weight:bold;">Execute the next command only if the first is successful</span><br /><br />I hope you got the idea now. Yes, we can use logical operator in between of our commands. To execute the next command in condition of when the first command is successfully accomplished, you can use logical AND operator which is double ampersand "&&". Look at this example:<br /><br /><code><br />$ mycommand1 && mycommand2<br /></code><br /><br />In this last example, mycommand2 will only be executed when mycommand1 is successful.<br /><br /><br />That's all for now mates.

Even if I previously said, I've already bored with the terminal coz I see it every day... <br /><img class='inline' src='http://coderstalk.googlepages.com/tongue.gif'/> it is good to know that actually, your terminal can do almost everything you wanna do in your linux box. I just don't like the way it looks and feel because I love <a href="http://artofapogee.blogspot.com" target="_blank">art and graphics</a>. I like the eye catchy graphics and also the live cubic desktop effect and so on. Anyway, I would like to share on how to use your <b>Pidgin from terminal console.</b> <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_QmenDvyMjlk/SM8a1XIsXkI/AAAAAAAAA4M/6s-ZowJwDOk/s1600-h/finch.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://3.bp.blogspot.com/_QmenDvyMjlk/SM8a1XIsXkI/AAAAAAAAA4M/6s-ZowJwDOk/s400/finch.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5246441594955783746" /></a><br />I have a lot to say about situations where you only got your terminal console to use programs in linux. But lets keep it short and go straight to the point now. The program to enable you to use <span style="font-weight:bold;">Pidgin via Terminal console</span> is called <span style="font-weight:bold;">Finch</span>. <span style="font-weight:bold;">Finch</span> as in the manual is <span style="font-weight:bold;">"A Pimpin’ Penguin console frontend to libpurple Instant Messaging client."</span> <br /><br />Run this command on your terminal to install finch in Ubuntu:<br /><pre id='linuxterm'>$ sudo apt-get install finch</pre><br />After installation, you can now use your Pidgin from the terminal console by running this command on your terminal:<br /><pre id='linuxterm'>$ finch</pre><br />As you wish to use terminal, you should already aware that you can't use your mouse (too bad for mousey... LOL). So, you have to be ready with keyboard shortcuts to use this application.

Just edit the <b><code>/etc/network/interfaces</code></b> file using any text editor on the server. By default, you should have nano and vi in your Ubuntu Server.<br /><br />The simplest and straight forward text editor is nano. So, use this command:<br /><br /><pre id='linuxterm'>$ sudo nano /etc/network/interfaces<br /></pre><br /><br />you should see the default file content like this:<br /><br /><pre dir="ltr" style="margin: 0px;padding: 3px;border: 1px inset;width: 98%;height: 230px;text-align: left; overflow: auto"><br /># This file describes the network interfaces available on your system<br /># and how to activate them.

So, to set it as static IP. Let say, we wanna setting like this:<br /><span style="font-weight:bold;"><br />=> Host IP address:</span> 10.1.1.100<br /><span style="font-weight:bold;">=> Netmask:</span> 255.255.255.0<br /><span style="font-weight:bold;">=> Network ID:</span> 10.1.1.0<br /><span style="font-weight:bold;">=> Broadcast IP:</span> 10.1.1.255<br /><span style="font-weight:bold;">=> Gateway/Router IP:</span> 10.1.1.254<br /><span style="font-weight:bold;">=> DNS Server:</span> 10.1.1.254<br /><br />You should change the file like this:<br /><br /><pre dir="ltr" style="margin: 0px;padding: 3px;border: 1px inset;width: 98%;height: 230px;text-align: left; overflow: auto"><br /># This file describes the network interfaces available on your system<br /># and how to activate them.

It's just because I'm getting busy with my workloads and some stuff to do with <a href="http://forums.ubuntu.com.my" target="_blank">Ubuntu Malaysia Community</a>. <img class='inline' src='http://coderstalk.googlepages.com/tongue.gif'/> Now I'm back, and I would like to share with you this cool IDE for programming in Linux called Geany.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_QmenDvyMjlk/SKDky5I35mI/AAAAAAAAA3I/Reucen_Czzc/s1600-h/geany_vte.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://1.bp.blogspot.com/_QmenDvyMjlk/SKDky5I35mI/AAAAAAAAA3I/Reucen_Czzc/s400/geany_vte.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5233434329987147362" /></a><br /><blockquote>Geany is a light-weight cross-platform GTK+ text editor based on Scintilla with basic Integrated Development Environment (IDE) features. It is designed to have limited dependency on separate packages and short load times. It is available for a wide range of operating systems, such as Windows, Linux, BSD and Solaris. Among the supported programming languages are (according to the documentation) C, Java, JavaScript, PHP, HTML, CSS, Python, Perl and Pascal.<br /><br />Geany is one of the more fully-featured editors on the Linux platform, as most Linux editors adopt a more minimalist philosophy. It is similar to Windows editors such as NoteTab or ConTEXT.<br /><br />It is Free Software licensed under the terms of the GNU GPL.<br /><br /><i>~ Cited From Wikipedia ~</i></blockquote><br />Previously, people use vim, nano or gedit to write codes for linux programming. Even thou there is not much problem in using all these text editors to write codes, productive people will need more things to have that will reduce their work and increase their output.<span class="fullpost"> While there are Anjuta, Eclipse, Netbeans and other complete IDE available, Geany come as a middle solution for people who don't wanna something crowded like full IDE but also need something more than a simple text editor.<br /><br />To install Geany on your Ubuntu, you can simply use Synaptic Package Manager and search for "geany" or run this line on your Terminal:<br /><br /><pre id="linuxterm">$ sudo apt-get install geany<br /></pre><br /><br />And this is what you can expect to get from Geany:<br /><ul><li>Code Folding - To stay focus within a complex codes, Code folding comes handy to hide big chunks of code and leave only what I'm working on right now.</li><li>saving the session - Geany can load files from the last session. Unfortunately, it doesn't remember where the cursor was within the file or which parts of code were folded.</li><li>sidebar - Before Geany, coders using vim or nano don't use these additional bars. This one is actually quite helpful. It lists all important code elements (functions, classes, variables, etc.) sorted in alphabetical order and lets us quickly jump to them. Also, we can right-click on a function name where it's used and quickly jump to a line when this function is declared (if it's declared in some file that's been opened, off course).</li><li>all standard features anybody would expect - syntax highlighting, code completion, tabs, auto indentation (either tabs or spaces), (un)commenting and decreasing/increasing indentation of multiple lines.</li><li>support for many languages - I counted 26 supported filetypes.</li><li>build system - it can compile, build, make all, make custom target, make object and execute.</li><li>multiple tiny bells and whistles, such as a color picker or the ability to insert predefined comments (for example description of a function).</li><li>and most of all - it doesn't do anything that annoys me. It's quite common for smallish applications to behave in a non-standard way.</li></ul><br /><br />You can also check out <a href="http://geany.uvena.de/Main/HomePage" target="_blank">Geany website</a> for more infos.

In the beginning, we just create a daughter board and attach it to a <a href="http://wiki.openwrt.org/OpenWrtDocs/Hardware/Linksys/WRT54GS" target="_blank">hacked LinkSYS WRT45GS</a> board which I've installed <a href="http://openwrt.org/" target="_blank">OpenWRT</a> so I can embed my bash script inside. But then, we go for TS-7260 board from embeddedarm.com to get more control on the RainGause for version two.<br /><br />Till now, I'm still upgrading the code for more features and stability. Well, that's all for now. <img class='inline' src='http://coderstalk.googlepages.com/sengih.gif'/> Enjoy what you're doing!!<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-2759476779593868178?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com4tag:blogger.com,1999:blog-3928190665450830956.post-37943246921509505512008-06-26T08:53:00.004+08:002008-06-26T10:05:16.605+08:00Fixing Read More link appear on Blogger FullpostThanks to <a href='http://paulescolarisdrunk.blogspot.com/' target='_blank'>Paul Escolar</a> who really use my code on <a href='http://coderstalk.blogspot.com/2008/06/how-to-create-expandable-post-summaries.html' target='_blank'>'How to create expandable post summaries in Blogger'</a> and spot a bug on that tutorial.<br /><br />Hence my code for this blog is already changed for other additional stuff. Sorry for that silly mistakes <img class='inline' src='http://coderstalk.googlepages.com/tongue.gif'/>. As I went to debug my tutorial, I found that whoever follow that tutorial properly will get the same result as Paul's blog. So, here is the explanation and how to fix it.<br /><br />Please check at the <a href='http://coderstalk.blogspot.com/2008/06/how-to-create-expandable-post-summaries.html#step-01' target='_blank'>last chunk of code on 'Step #1 - Edit your template code'</a>. The old code should look like this:<br /><br /><pre id='blogcode'><br /><b:if cond='data:post.labels'><br /> <b:loop values='data:post.labels' var='label'><br /> <b:if cond='data:label.name == &quot;more&quot;'><br /> <a expr:href='data:post.url'>...<b>Read more</b></a><br /> </b:if><br /> </b:loop><br /></b:if><br /><br /></pre><br /><br />where the previous screenshot is this:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_QmenDvyMjlk/SFAHEUsjVfI/AAAAAAAAA0s/VvZxrSNiawU/s1600-h/before-after.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://3.bp.blogspot.com/_QmenDvyMjlk/SFAHEUsjVfI/AAAAAAAAA0s/VvZxrSNiawU/s400/before-after.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5210672539724109298" /></a><br /><br />What this code do is checking the 'more' label and put that 'Read More' link at the end of your post, regardless you are in fullpost or not. So, to wipe it out when we are in fullpost, you just have to add this two lines of code, before and after that code chunk:<br /><br /><pre id='blogcode'><br /><b:if cond='data:blog.pageType != &quot;item&quot;'><br /> <span style='color:#aaaaaa;'><b:if cond='data:post.labels'><br /> <b:loop values='data:post.labels' var='label'><br /> <b:if cond='data:label.name == &quot;more&quot;'><br /> <a expr:href='data:post.url'>...<b>Read more</b></a><br /> </b:if><br /> </b:loop><br /> </b:if></span><br /></b:if><br /><br /></pre><br /><br />In blogger layout code, the fullpost page type is called 'item'. So, this <b>'if statement'</b> is added to check that we are not in <b>'item'</b> post and only do loop through the labels and add the Read More links then. <br /><br />That's it, you may save your template now and see the difference. Good Luck!!<img class='inline' src='http://coderstalk.googlepages.com/sengih.gif'/><br /><br/><br /><div style="padding: 10px; background-color: rgb(255, 250, 218);"><b>You may also love to read:</b><br /><ul><li><a href='http://coderstalk.blogspot.com/2008/06/how-to-create-expandable-post-summaries.html'>How to create expandable post summaries in Blogger</a></li><li><a href='http://coderstalk.blogspot.com/2007/07/how-to-show-and-hide-text-in-blog-post.html' target='_blank'>How to Show and Hide Text in Blog Post</a></li><li><a href='http://coderstalk.blogspot.com/2008/02/how-to-show-and-hide-text-in-blog-post.html' target='_blank'>How to Show and Hide Text in Blog Post with teaser</a></li></ul></div><br /><br/><br /></span><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-3794324692150950551?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com23tag:blogger.com,1999:blog-3928190665450830956.post-11629120434359332312008-06-12T02:30:00.026+08:002008-09-02T10:59:43.551+08:00How to create expandable post summaries in Blogger<a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_QmenDvyMjlk/SFAmZ6p90YI/AAAAAAAAA1M/o_QvZC99At8/s1600-h/blogspot.jpg"><img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;" src="http://3.bp.blogspot.com/_QmenDvyMjlk/SFAmZ6p90YI/AAAAAAAAA1M/o_QvZC99At8/s200/blogspot.jpg" border="0" alt=""id="BLOGGER_PHOTO_ID_5210706995551523202" /></a>I've been tweaking my blog template because I've already bored with my old default template that I use previously. While working on this template, I'm thinking that it may be cool to have my long post to be truncated and <span style="font-weight:bold;">have the "read more" link</span>.<br /><br />I found the <span style="font-weight:bold;">code</span> from <span style="font-weight:bold;">Blogger Help</span> to do this. However, there is one issue with their code where the "read more" link will appear regardless of whether a post has been truncated or not. You can check it out at <a href='http://help.blogger.com/bin/answer.py?hl=en&answer=42215' target='_blank'>help.blogger.com on How can I create expandable post summaries?</a>. If you have already read them, you should notice the disadvantages under the <span style="font-weight:bold;">Note list</span> which says:<br /><blockquote><ul><li>Disadvantages: Requires changes to the posts themselves, rather than to the template only. However, <span style="color:magenta">the "read more" link is in the template, so it will appear regardless of whether a post has been truncated or not.</span> <span style="color:green">(Modifying this feature is left as an exercise for the reader.)</span></li></ul></blockquote><br />Do you think it is a good exercise? So, how many of you have already solve this exercise? I've been browsing through pages of google results and found that currently, I didn't see anybody solve and publish the answer for this exercise with just the <span style="font-weight:bold;">blogger layout code</span> and without using other <span style="font-weight:bold;">javascript code</span>. I do the search because I'm a lazy coder where I don't wanna spend my precious time to reinvent the wheel. Anyway, after a few minutes of thinking, I got an idea on how to solve this problem. And as usual, I'm happy to share my solution with you.<span class="fullpost"> <br /><br />Let's make it short now, here's the tutorial:<br /><br /><span style="font-size:1.5em;color:#ff6600"><strong>How can I create expandable post summaries that only show the "read more" link if post is truncated?</strong></span><br />With this hack, you can choose to display a select amount of text from the beginning of each post as a teaser instead of showing the entire post on the front page of your blog. Then when people want to read the rest of the post, they can click a <span style="color:green">“read more”</span> link to see the full post. This is very handy if you have lots of long articles all on one page. (Note that you’ll need to have <a href="http://help.blogger.com/bin/answer.py?answer=42049" target="_blank">post pages</a> enabled in order to make this feature work.)<br /><br /><span style="color:#1069f1;font-size:1.5em;"><b>Step #1 - Edit your template code</b></span><br />To edit your template code, you have to go to your <span style="font-weight:bold;">Layout > Edit HTML</span> tab. Tick the <span style="font-weight:bold;">Expand Widget Templates</span> to have all the codes. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/_QmenDvyMjlk/SE_zN9RJQfI/AAAAAAAAA0c/0t-wwUKZWos/s1600-h/layout-edit-html.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://2.bp.blogspot.com/_QmenDvyMjlk/SE_zN9RJQfI/AAAAAAAAA0c/0t-wwUKZWos/s400/layout-edit-html.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5210650715001274866" /></a><br /><br />It is easier to copy all code and paste it to your text editor. To copy all code, click on the code area once and then press <b>Ctrl+A</b> to <span style="font-weight:bold;">Select All</span>. Press <span style="font-weight:bold;">Ctrl+C</span> to <span style="font-weight:bold;">copy the selected codes</span>, open your text editor and paste it in. Now you have your code ready to edit.<br /><br />Add this code just before the <code style='color:green'><b:skin></code> tag on your template code:<br /><br /><pre id='blogcode'><br /><style><br /><b:if cond='data:blog.pageType == &quot;item&quot;'> <br /> span.fullpost {display:inline;}<br /><b:else/><br /> span.fullpost {display:none;} <br /></b:if><br /></style><br /><br /></pre><br /><br />Here's how it should look. The yellow box in the image below shows your newly added code:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_QmenDvyMjlk/SE_6B8kmlKI/AAAAAAAAA0k/uT-lPaFslCk/s1600-h/code-1.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://3.bp.blogspot.com/_QmenDvyMjlk/SE_6B8kmlKI/AAAAAAAAA0k/uT-lPaFslCk/s400/code-1.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5210658205237417122" /></a><br /><a id='step-01'></a><br />And then you have to find <code style='color:green'><data:post.body/></code> tag using Ctrl+F or find function in your text editor and paste this code just before the <code style='color:green'></p></code> tag, right after the <code style='color:green'><data:post.body/></code> tag:<br /><br /><pre id='blogcode'><br /><b:if cond='data:post.labels'><br /> <b:loop values='data:post.labels' var='label'><br /> <b:if cond='data:label.name == &quot;more&quot;'><br /> <a expr:href='data:post.url'>...<b>Read more</b></a><br /> </b:if><br /> </b:loop><br /></b:if><br /><br /></pre><br /><br />And the screenshot. The yellow box shows your newly added code:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_QmenDvyMjlk/SFAHEUsjVfI/AAAAAAAAA0s/VvZxrSNiawU/s1600-h/before-after.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://3.bp.blogspot.com/_QmenDvyMjlk/SFAHEUsjVfI/AAAAAAAAA0s/VvZxrSNiawU/s400/before-after.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5210672539724109298" /></a><br /><br />My solution here is by checking the label whether it have <span style='color:green;'>"more"</span> label. So, in every post that you decided to have the "read more" link, you have to add this label. I'm adding a loop to read the labels for each post and inside the loop, there is an IF statement to check whether it have the "more" label.<br /><br />You should notice this line with:<br /><code style="color:green"><b:if cond='data:label.name == &quot;<span style="color:#005500;font-weight:bold;">more</span>&quot;'></code><br />where the word 'more' in bold here is the label name. You can substitute this with any word you like but make sure you will only add that label to the post where you want to have the <span style="color:green;">"read more"</span> link.<br /><br />And now, you can differentiate the truncated post. <img class='inline' src='http://coderstalk.googlepages.com/sengih.gif'/> After verifying your code, copy it from your text editor and overwrite your HTML template code. Click on<span style="font-weight:bold;"> Save Template</span> and you are done with the first step. Check your code carefully if Blogger fail to save it. Maybe you have missed any <code style="color:green;font-weight:bold;">'<'</code> or <code style="color:green;font-weight:bold;">'>'</code> in your code.<br /><br /><a href='http://coderstalk.blogspot.com/2008/06/fixing-read-more-link-appear-on-blogger.html' target='_blank'><b>UPDATE!!: Please Read - Fixing Read More link appear on Blogger Fullpost</b></a><br /><br /><span style="color:#1069f1;font-size:1.5em;"><b>Step #2 - Add Class Tag in your default Post Template</b></span><br />The next step is optional to keep the class tag handy on every post you would like to have expandable post summaries. To add this, you can just go to <span style="font-weight:bold;">Settings > Formatting</span> tab on your blog settings. Scroll to the bottom and you will see the <span style="font-weight:bold;">Post Template</span> option. Then, put this code:<br /><br /><pre id='blogcode'><br /><span class="fullpost"><br /><br /></span><br /><br /></pre><br /><br />Here's the screenshot:<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/_QmenDvyMjlk/SFAW7miR2xI/AAAAAAAAA00/WMO9w5H5XM4/s1600-h/template.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://2.bp.blogspot.com/_QmenDvyMjlk/SFAW7miR2xI/AAAAAAAAA00/WMO9w5H5XM4/s400/template.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5210689982080080658" /></a><br /><br />After that, click on <span style="font-weight:bold;">Save Settings</span> and you are done.<br /><br /><span style="color:#1069f1;font-size:1.5em;"><b>Step #3 - Creating your expandable post</b></span><br />You can now follow the same way like in the blogger help to create your expandable post. When writing your new post, anything you put above the <code style='color:green'><span class=”fullpost”></code> tag will be the teaser text. The main body of your post needs to go in between the <code style='color:green'><span class=”fullpost”></code> and <code style='color:green'></span></code> tags. When you have finish typing your post, make sure you add <span style='color:green;'>"more"</span> label in order for the “read more” link to work properly.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/_QmenDvyMjlk/SFAXEkbRF0I/AAAAAAAAA08/BqzxJW5BcOI/s1600-h/post-sample.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://2.bp.blogspot.com/_QmenDvyMjlk/SFAXEkbRF0I/AAAAAAAAA08/BqzxJW5BcOI/s400/post-sample.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5210690136132622146" /></a><br /><br />Now, you can Publish your post, and see the result.

However, if you have an rpm file for a package you wish to install, and if you cannot find a .deb debian package in any of the Ubuntu repositories or elsewhere, you can use the <a href="http://kitenet.net/programs/alien/" target="_blank">alien package converter application</a> to install the .rpm file.<br /><br /><blockquote>Alien is a program that converts between the rpm, dpkg, stampede slp, and slackware tgz file formats. If you want to use a package from another distribution than the one you have installed on your system, you can use alien to convert it to your preferred package format and install it.<br /><br />Despite the large version number, alien is still (and will probably always be) rather experimental software. It has been used by many people for many years, but there are still many bugs and limitations.<br /><br />Alien should not be used to replace important system packages, like sysvinit, shared libraries, or other things that are essential for the functioning of your system. Many of these packages are set up differently by Debian and Red Hat, and packages from the different distributions cannot be used interchangably. In general, if you can’t uninstall the package without breaking your system, don’t try to replace it with an alien version.<br /></blockquote><br /><h4 style="font-weight:bold;font-size:5;">How to Install RPM Files Using Alien</h4><h4>Installing Alien</h4><br />The <strong>alien</strong> can be installed from the Ubuntu <em>Universe</em> repository by adding the repository to your list of sources and issuing this commands:<span class='fullpost'><br /><pre id=linuxterm>$ sudo apt-get update<br />$ sudo apt-get install alien</pre><br /><br /><h4>Installing the .rpm file</h4><br />To install the .rpm file, you have to convert it first to a .deb file which then can be installed on Ubuntu.<br />Assuming that you downloaded the package to your Desktop (~/Desktop is the directory)<br />You can convert the .rpm to a .deb by using the following commands:<br /><br /><pre id=linuxterm>$ cd ~/Desktop</pre>-This will change the directory to your desktop, where you have the .rpm file. <br /><br /><pre id=linuxterm>$ sudo alien -k name-of-rpm-file.rpm</pre>- This will convert the .rpm to a .deb.<br />- The “-k” will keep the version number. Otherwise alien adds a “1″ to the version number.<br /><br /><pre id=linuxterm>$ sudo dpkg -i name-of-deb-file.deb</pre>- This will install the .deb package<br /><br />Feel free to read the alien manpage for more details on how you can convert other kinds of packages and the options available.<br /><br />That's all for now, Good Luck!!<img class='inline' src='http://img458.imageshack.us/img458/6599/sengih2ys5.gif'/><br />via [<a href="http://ubuntu.wordpress.com/2005/09/23/installing-using-an-rpm-file/" target="_blank">ubuntu.wordpress</a>]<br /><br/></span><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-1448403297074059291?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com1tag:blogger.com,1999:blog-3928190665450830956.post-71069147618500554512008-06-05T18:57:00.011+08:002010-02-11T11:31:17.330+08:00Bash Scripting - Script execution counterThis <span style="font-weight:bold;">Linux shell script</span> does nothing than just increasing n value every time it is executed and then keep the value in a file. When the value goes greater than 10, it will drop back to 1. Uhhh... this reminds me to the increasing of the fuel price. But that fuel price will just increase and will never drop back... Lol... Anyway, I wrote this <span style="font-weight:bold;">bash script</span> just to make a permanent variable to be used as bash script running counter. With this code, I can count how many time the script have been executed.<br /><br />Here's the code:<br /><pre dir="ltr" style="margin: 0px;padding: 3px;border: 1px inset;width: 98%;height: 230px;text-align: left; overflow: auto">#!/bin/sh<br /><br />nfilename="./nvalue"<br /><br />n=0<br />touch $nfilename<br />. $nfilename<br /><br />echo "current n value is $n"<br /><br />n=$(expr $n + 1)<br /><br />if [ $n -gt 10 ]; then<br /> n=1<br />fi<br /><br />echo "new n value is $n"<br /><br />echo "n=$n" > $nfilename<br /></pre><br />Here's the step for testing the script for newbies bash scripter.<br /><br />1. Create one text file in your home folder. In this example I'm using <span style="font-weight:bold;">ncounter</span> as the file name:<br /><pre id=linuxterm>apogee@apogee-persiasys:~ gedit ncounter<br /></pre><br />2. Copy and paste the codes in this file, then save and close it.<br /><br />3. Change the file permission to executable:<br /><pre id=linuxterm>apogee@apogee-persiasys:~ chmod +x ncounter<br /></pre> <br />4. Then you can test it... here's my output example:<br /><pre id=linuxterm>apogee@apogee-persiasys:~$ ./ncounter <br />current n value is 0<br />new n value is 1<br />apogee@apogee-persiasys:~$ ./ncounter <br />current n value is 1<br />new n value is 2<br />apogee@apogee-persiasys:~$ ./ncounter <br />current n value is 2<br />new n value is 3<br />apogee@apogee-persiasys:~$ ./ncounter <br />current n value is 3<br />new n value is 4<br />apogee@apogee-persiasys:~$ <br /></pre><br />Feel free to experiment and change the <span style="font-weight:bold;">./nvalue</span> file location to somewhere else where you have read and write permission. This is just another linux shell script that I haven't used yet... heheh<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-7106914761850055451?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com0tag:blogger.com,1999:blog-3928190665450830956.post-84212149215050423552008-06-03T09:08:00.011+08:002008-06-11T17:34:16.300+08:00PC in a KeyboardHave you ever wished of having a desktop where your super slim LCD monitor attached to just a keyboard?

This is very helpfull to backup your CD and DVD into ISO images:<br /><br />To make an ISO from your CD/DVD, place the media in your drive but do not mount it. If it automounts, unmount it. <br /><br /><br /><br /><br/><br />for dvd:<br /><pre id="linuxterm">$ dd if=/dev/dvd of=mydvd.iso</pre><br />for cdrom:<br /><pre id="linuxterm">$ dd if=/dev/cdrom of=mycd.iso</pre><br />for scsi cdrom:<br /><pre id="linuxterm">$ dd if=/dev/scd0 of=mycd.iso</pre><br /><br />And if you wanna make an ISO from files on your hard drive, create a directory which holds the files you want. Then use the mkisofs command.<br /><br /><pre id="linuxterm">mkisofs -o /tmp/mycd.iso /tmp/directory/</pre><br /><br />This results in a file called cd.iso in folder /tmp which contains all the files and directories in /tmp/directory/.<br /><br />For more info, see the man pages for mkisofs, losetup, and dd, or see the CD-Writing-HOWTO at http://www.tldp.org.

When we need software, just google up and seek on what you need, maybe you got a free version or sometimes cracked by someone else... It doesn't matter. <br /><br />The only things that matter is, do you really trust the software that you recently downloaded won't do anything wrong to you? If you have no worries about it before, you may need to read this Jeff Atwood's post about <a href="http://www.codinghorror.com/blog/archives/001072.html" target="_blank">A Question of Programming Ethics</a> on his CodingHorror blog.

Pretty cool because previously I've watched japanese anime about cars which influence people to be like the anime heroes like Inital-D and so on. But that works for car lover. And what about coders or programmers? Worry not, here it comes... Battle Programmer Shirase.<br /><br /><center><object width="425" height="355"><param name="movie" value="http://www.youtube.com/v/RyWYYqyM85E&hl=en"></param><param name="wmode" value="transparent"></param><embed src="http://www.youtube.com/v/RyWYYqyM85E&hl=en" type="application/x-shockwave-flash" wmode="transparent" width="425" height="355"></embed></object><br /></center><br /><br />I think I'm really late to know this because it have already aired since 2003. Wow... <img class='inline' src='http://img458.imageshack.us/img458/1977/tongue2fe6.gif'/><br /><br />The story of Battle Programmer Shirase revolves around a "freelance programmer" named Akira Shirase. He's a very talented, yet mysterious computer programmer. Because of his incredible abilities, he's contacted by several individuals (curiously, all of them are very similar persons named Akizuki Kaoru) to do all sorts of strange computer-related hacking/security jobs. He's a very quiet guy who lives alone in a small apartment near his niece's house. At first, the episodes revolved around some freelance jobs that highlighted his abilities - however, later on in the series, characters came back and offered help or plot twists. The school that Shirase had gone to had been hinted throughout the series, and it finally made an appearance in the last episode, when some of the characters began to show their hidden relationships to the others. <br /><br />The series' story focus is on computers and ecchi comedy. The original series spans 5 story arcs across 15 episodes of 12 minutes each. According to wikipedia, the series was not continued. Anyway, just enjoy them... <img class='inline' src='http://img458.imageshack.us/img458/6599/sengih2ys5.gif'/> and hope there is continuation on this...<br /><br /><br/><br /><div style="padding: 10px; background-color: rgb(255, 250, 218);"><b>You may also love to read:</b><br /><ul><li><a href='http://coderstalk.blogspot.com/2009/01/battle-programmer-shirase-episode-2.html'>Battle Programmer Shirase - Episode 2</a></li></ul></div><br /><br/><br /><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-7244203148257922184?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com1tag:blogger.com,1999:blog-3928190665450830956.post-25963264838609771552008-05-21T11:31:00.005+08:002008-06-12T19:00:41.029+08:00How to build your own low cost superb wifi booster.Wireless have been widely used in houses and offices.

The issue is, when I use a new SIM card, sometimes that SIM card have pin number which make the modem locked and cannot dial or connect to the internet via GPRS until I unlock the GSM Modem by issuing the pin number. That was annoying when you have put the pin number every time it is booting while you suppose to just leave this device to work and connect automatically.<br /><br />Actually, in order to fix this issue, I can just disable the SIM card pin. So, I would like to share my routine with new SIM card with pin number, assuming you knew some AT+Command basic and how to use it. Here's how to disable your SIM card pin via Wavecom Meastro, Fastrack or any compatible GSM modems:<br /><br /><ol><li>Connect your modem to your computer.</li><br /><li>Open up serial terminal. I'm using <span style="font-weight:bold;">minicom</span> coz I'm on Linux box. On Windows, you can use HyperTerminal.</li><br /><li>Turn on your GSM Modem</li><br /><li>Issue an AT command to test it. You may want to change to the right baudrate in order to get the reply:<br /><code>AT</code><br />the expected reply is:<br /><code>OK</code><br /></li><br /><li>Check if the Modem is locked by the SIM pin by issuing:<br /><code>AT+CPIN?</code><br /><br />the expected reply for unlocked modem should be: <br /><code>+CPIN: READY</code><br /><br />or else, you have to unlock it by issuing: (example: my default SIM card pin is 1234)<br /><code>AT+CPIN="1234"</code><br /><br />and it will reply <code>OK</code><br /></li><li>Now, we can disable the pin by issuing:<br /><code>AT+CLCK="SC",0,"1234"</code><br /><br />where 1234 is your current SIM pin.</li></ol><br />That's all. You can now restart the modem and use it with your automated GPRS dialer. I don't know if this GSM AT Command will also works on siemens gsm modem or other GSM modems. You can try it and feel free to leave your comments. <img class='inline' src='http://img458.imageshack.us/img458/6599/sengih2ys5.gif'/> Have fun!<br /><br/><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-4497466584385645979?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com7tag:blogger.com,1999:blog-3928190665450830956.post-71114195065566625612008-04-12T11:36:00.006+08:002008-04-12T13:27:09.856+08:00Embedded System in Malay LanguageFor technical writers who works with translations of documentation and manuals in <span style="font-weight: bold;">Bahasa Malaysia</span> would already noticed that it is really hard to translate computer or IT related documentations from english to malay. As I have already involved in my own <a href="http://coderstalk.blogspot.com/2008/03/malay-translation-code.html" target="_blank" title="Malay Translation Code">personal project in translation</a>, I found that there is difficulties in translating computer related terms into <span style="font-weight: bold;">Malay Language</span> without falling into other meanings where the real means of that terms isn't achieved or else I will up to creating new terms in Malay language that wouldn't be agreed by other documents with the same terms, translated by other translator.<br /><br /><a href="http://www.amazon.com/gp/product/0750698691?ie=UTF8&tag=coderstalkblo-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=0750698691"><img src="http://ecx.images-amazon.com/images/I/41YIEC7v1-L._SL500_BO2,204,203,200_PIsitb-dp-500-arrow,TopRight,45,-64_OU01_AA240_SH20_.jpg" style="margin: 0px 10px 10px 0px; float: left;" border="0" /></a><img src="http://www.assoc-amazon.com/e/ir?t=coderstalkblo-20&l=as2&o=1&a=0750698691" alt="" style="border: medium none ! important; margin: 0px ! important;" border="0" height="1" width="1" />I've been searching around for any standard meaning of <span style="font-weight: bold;">Embedded System</span> or Embedded Hardware in Malay language. I found that <span style="font-weight: bold;">Embed means 'tanam'</span> which also means buried if translated back to English. Actually, there is a lot of other words with the same meaning in Malay and that adds more difficulties in finding the right word that exactly match the computer terms.<br /><br />Other translation of <span style="font-weight: bold;">Embed is 'benam'</span>. While using my imagination on what will people read when I say 'Perkakasan Tertanam' (Embedded Hardware) where someone would imagine that there is a device that is buried under the sand or mud. I would laugh myself if someone would think like that. This is because the word 'tanam' itself is closely related to 'tanaman' (plantations) where it would quickly divert someones imagination onto that something is buried under the land.<br /><br />So, I come out with another malay word that might be close to the meaning of <span style="font-weight: bold;">Embed which is 'benam'</span>. While trying to say<span style="font-weight: bold;"> 'Perkakasan Terbenam' </span>or <span style="font-weight: bold;">'Sistem Terbenam'</span> (Embedded System), I think this should be of the right meaning of it... I hope so <img class="inline" src="http://img458.imageshack.us/img458/1977/tongue2fe6.gif" />. I also found that there is others who would be agreed with my terms even thou he translate this terms in Indonesian language. If you haven't heard any Malay or Indonesian Language, I can say that Malay and Indonesian Language is related in each other. The oldest and richest language may obviously Indonesian, but Malays also have our own way of translating terms. I will sometimes search and peep on how they translate IT terms from English to Indonesian in order to get the idea but I won't simply use their terms because sometimes they use words that will obviously sounds like Indonesian. Well, I don't want it to sound more like Indonesian translated documents either.<img class="inline" src="http://img458.imageshack.us/img458/1977/tongue2fe6.gif" /> Owh, I just found that Kukuh Prasetyo, an indonesian blogger is using the same terms <a href="http://blogcoffee.net/archives/2007/05/29/istilah-embedded-systems-indonesia/" target="_blank">'Sistem Terbenam' for Embedded System</a> like me too.<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_QmenDvyMjlk/SABHURVjhnI/AAAAAAAAAv4/TLO8qTsSHc0/s1600-h/paksamad.png" title="Datuk A.

Or, if you have found any better or standard terms for that in Malay Language, please leave your comments below.

I don't want to tell much about that company since I've already left the company and now working in another small company doing another automation stuff. I learned a lot that programing and electronic can be combined to create more hi-tech appliances.<br /><br />Electronic and programming is fun and fascinating. Take a look at this <span style="color: rgb(255, 0, 0); font-weight: bold;">cool DIY gadget</span> called <span style="font-weight: bold;">Plasma Speaker</span> or <span style="font-weight: bold;">Plasma Tweeter</span>. But be careful because this cool things is dangerous too.<img class="inline" src="http://img458.imageshack.us/img458/1977/tongue2fe6.gif" /><br /><br />There are various versions of this FM modulated plasma arc speakers. Even thou <span style="font-weight: bold;">Plasma Speaker</span> is not new in any way because they’ve been around since the late 1950’s. It is a cool thing for me. It sounds just like regular speakers, but plasma speakers work by creating compression waves in the air.

I gotta build and try this if I have time. Here's more info on this Plasma Speaker.<br /><br /><blockquote><span style="font-weight: bold;">Plasma speakers</span> (sometimes called flame speakers if the source of the plasma is combustion rather than gas ionization) are a form of loudspeaker which vary the intensity of a plasma, rather than using a magnetic field to push or pull a conventional driver, to create compression waves in air (which a listener perceives as sound).<br /><br />In a normal loudspeaker design, the inertia of the driver will resist an instantaneous change in its position as the magnetic field varies with the input. This decreases the fidelity of the speaker, as the input is distorted due to the physical limitations of the device, particularly for strong high frequencies. (This limitation is one of the reasons why tweeters are so much smaller than woofers.) In a plasma speaker, this limitation effectively does not exist, as the air itself is driven directly by expansion of the plasma as the current through it varies. (Ionization of a gas causes its electrical resistance to drop significantly; see for example the "Jacob's ladder" for an explanation.)<br /><br />Plasmatronics produced a commercial plasma speaker that used a helium tank to provide the ionization gas; other designs (some of which date to the 1950s) use combustion of natural gas or even candles[citation needed] to produce a plasma, through which current is then passed as in the gas plasma designs (though combustion designs do not require the initial high-voltage to create the plasma).<br /><br />The plasma speaker design is a member of the family of so-called massless speakers.<br /><br />--:Quoted from Wikipedia</blockquote><br />So, If you are thinking about building this <span style="color: rgb(255, 0, 0); font-weight: bold;">cool gadget</span> too, you can get more info on how they build this cool gadget at <a href="http://www.plasmatweeter.de/eng_plasma.htm" target="_blank" title="Howto Build Plasma Speaker">Ulrich Haumann's DIY PLASMA TWEETER</a>.

You may noticed that on the CSS code would be a list of redundant code in order to hack this out.<br /><br />However, while surfing today, I found one good simple tricks for min-height and min-width CSS code that is compatible across all common versions of Safari, Firefox and IE. Maybe you already found and use it. I'm posting this for my notes and maybe it could be helpful for others too...<img class='inline' src='http://img458.imageshack.us/img458/1977/tongue2fe6.gif'/><br /><br /><span style="font-weight:bold;">The Cross Browser min-height CSS</span><br /><code><br /> .foo {<br /> min-height:100px;<br /> height: auto !important;<br /> height: 100px;<br /> }</code><br /><br />This works because all of the more recent browsers will understand and respect the min-height setting as well as the <span style="font-weight:bold;">!important</span> designation. So in the example above, the block will be given the <span style="font-weight:bold;">min-height</span> setting you specify, and the height:auto will take precedence over the height:100px, even though it appears earlier in the code. With content shorter than 100px, the min-height setting is observed, and with content that is longer, the block is sized to fit the content.<br /><br />By the way, in the case of older versions of IE, neither the <span style="font-weight:bold;">min-height</span> parameter nor the <span style="font-weight:bold;">!important</span> designation are supported. Instead, the browser essentially sees a <span style="font-weight:bold;">height:auto</span>, immediately followed by a <span style="font-weight:bold;">height:100px</span>, and the latter takes precedence. Lucky for us, height parameter in older versions of IE function exactly like the min-height parameter. When content expands past the size of the element, it grows to accommodate it. When content is shorter, the specified height is respected.<br /><br />Logically, this should also works on min-width.<br /><br /><span style="font-weight:bold;">The Cross Browser min-width CSS</span><br /><code><br /> .bar {<br /> min-width:100px;<br /> width: auto !important;<br /> width: 100px;<br /> }</code><br /><br />If you wonders, I got this trick from <a href="http://www.hackszine.com/blog/archive/2008/03/easiest_crossbrowser_css_minhe.html?CMP=OTC-7G2N43923558" target="_blank">Hackszine</a>.

For all advanced geek who read this blog, please ignore this post... <img class="inline" src="http://coderstalk.googlepages.com/tongue.gif" /> I just wanna help myself not to teach the same basic thing on every newbies friends that really need help.<br /><br />OK guys, back to the howto...<br /><br />There are two ways to create a hyperlink on your blog post. One is the simple GUI way and the other is coders way. I prefer the coder way as I can have more control on it.<br /><br />I like to teach by example. So, let say you wanna create a hyperlink on this line of words...<br /><br /><blockquote>You can go <span style="color: rgb(0, 153, 0); font-weight: bold;">here</span> to see my art blog<br /></blockquote><br />where you wanna link the word <span style="font-weight: bold;">"here"</span> to the other page on your blog or on the internet. In this example, I wanna link it to my Art Of Apogee Blog post with the address:<br /><code>http://artofapogee.blogspot.com/2008/03/gimp-best-free-photoshop.html</code><br /><br />And here is how to do it using both ways...<span class='fullpost'><br /><br /><span style="font-size:130%;"><span style="font-weight: bold;font-family:arial;" >The simple GUI way</span></span><br /><br />If you rollover every button on your Compose toolbar, you can see one button called "Link" where the word Link will pop up when you hover the button like this:<br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/_QmenDvyMjlk/R_y3VCMvaZI/AAAAAAAAAvI/pCDZm9DkU7c/s1600-h/howto-link3.png"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="http://2.bp.blogspot.com/_QmenDvyMjlk/R_y3VCMvaZI/AAAAAAAAAvI/pCDZm9DkU7c/s400/howto-link3.png" alt="" id="BLOGGER_PHOTO_ID_5187222442819414418" border="0" /></a><br />Now, all you have to do is to <span style="font-weight: bold;">highlight</span> or <span style="font-weight: bold;">select</span> the word "here" on that phrase, click the <span style="font-weight: bold;">link button</span> or press <span style="font-weight: bold;">Ctrl+Shift+A</span>, type or paste the URL (the link address) and <span style="font-weight: bold;">press Enter</span> or click <span style="font-weight: bold;">OK</span>.<br /><br />Pretty fast huh?... here is the slow motion...<br />1. Select the word "here"<br /><br /><div style="text-align: left;"><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://4.bp.blogspot.com/_QmenDvyMjlk/R_y8ciMvaaI/AAAAAAAAAvQ/v3o-rrHFDvw/s1600-h/select-here.png"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="http://4.bp.blogspot.com/_QmenDvyMjlk/R_y8ciMvaaI/AAAAAAAAAvQ/v3o-rrHFDvw/s400/select-here.png" alt="" id="BLOGGER_PHOTO_ID_5187228069226572194" border="0" /></a><br />2. Click on the <span style="font-weight: bold;">Link</span> <span style="font-weight: bold;">Button</span> or press <span style="font-weight: bold;">Ctrl+Shift+A</span><br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_QmenDvyMjlk/R_y_GSMvabI/AAAAAAAAAvY/axA3XE8DBlM/s1600-h/link-button.png"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="http://3.bp.blogspot.com/_QmenDvyMjlk/R_y_GSMvabI/AAAAAAAAAvY/axA3XE8DBlM/s400/link-button.png" alt="" id="BLOGGER_PHOTO_ID_5187230985509366194" border="0" /></a><br />3. Type or paste your link address (Um... technically it is called <a href="http://en.wikipedia.org/wiki/Uniform_Resource_Locator" target="_blank" title="Uniform Resource Locator">URL</a>) and click <span style="font-weight: bold;">OK</span><br /></div><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://2.bp.blogspot.com/_QmenDvyMjlk/R_zBtCMvacI/AAAAAAAAAvg/VRLuQPrpfnA/s1600-h/press-ok.png"><img style="margin: 0px auto 10px; display: block; text-align: center; cursor: pointer;" src="http://2.bp.blogspot.com/_QmenDvyMjlk/R_zBtCMvacI/AAAAAAAAAvg/VRLuQPrpfnA/s400/press-ok.png" alt="" id="BLOGGER_PHOTO_ID_5187233850252552642" border="0" /></a><br /><br />Believe it or not, it's done...<br /><br /><span style="font-size:130%;"><span style="font-weight: bold;font-family:arial;" >The Coder way</span></span><br /><br />The coder way may be a bit hard for newbies who's not familiar with HTML tags. But it is good if you wanna have more control on your resulting output...<br /><br />Using the same example situation, now go to the <span style="font-weight: bold;">Edit Html</span> tab. It is on the top-right of your typing area.<br /><br />And using the same method, select the word, click the <span style="font-weight: bold;">Link Button</span> or press <span style="font-weight: bold;">Ctrl+Shift+A</span>, paste the URL and click OK. But now, you can see the text should look something like this:<br /><br /><code>You can go <a href="http://artofapogee.blogspot.com/2008/03/gimp-best-free-photoshop.html">here</a> to see my art blog</code><br /><br />Actually, it is basically done but I personally would love to add more things to that link code. For example, if I want a descriptive word to pop up and say "Art Of ApOgEE Blog", I can simply add this line of code:<br /><br /><code>title="Art Of ApOgEE Blog"</code><br /><br />just before the <span style="font-weight: bold;">></span> character. And I can also add this line:<br /><br /><code>target="_blank"</code><br /><br />if I want my visitor to open up new window or tab if they click on that link. Very helpful for web surfer like me who don't wanna get lost from my main reading and have to click back button to reload my currently reading page...<img class="inline" src="http://coderstalk.googlepages.com/sengih.gif" /><br /><br />Hey, there is more you can do with the HTML tag. You can do further reading on <a href="http://www.w3schools.com/tags/tag_a.asp" target="_blank" title="HTML A TAG">HTML Anchor tag</a> and use your imagination to add more.<br /><br />As usual, Here's the result of this howto:<br /><span style="font-weight:bold;"><br />the code:</span><br /><br /><code>You can go <a href="http://artofapogee.blogspot.com/2008/03/gimp-best-free-photoshop.html" target="_blank" title=" Art Of ApOgEE Blog ">here</a> to see my art blog<br /></code><br /><span style="font-weight:bold;">the output:</span><br /><br />You can go <a href="http://artofapogee.blogspot.com/2008/03/gimp-best-free-photoshop.html" target="_blank" title=" Art Of ApOgEE Blog ">here</a> to see my art blog<br /><br />OK mates, that's all for now. Hope it helps all of you and you can start hyper linking your blog. Feel free to add a link to my blog too hehehehe... <img class="inline" src="http://coderstalk.googlepages.com/tongue.gif" /> Have Fun!!<br /><br/><br /><div style="padding: 10px; background-color: rgb(255, 250, 218);"><b>You may also love to read:</b><br /><ul><li><a href='http://coderstalk.blogspot.com/2007/07/how-to-show-and-hide-text-in-blog-post.html' target='_blank'>How to Show and Hide Text in Blog Post</a></li><li><a href='http://coderstalk.blogspot.com/2008/02/how-to-show-and-hide-text-in-blog-post.html' target='_blank'>How to Show and Hide Text in Blog Post with teaser</a></li><li><a href="http://coderstalk.blogspot.com/2008/06/how-to-create-expandable-post-summaries.html" target="_blank">How to create expandable post summaries in Blogger</a></li><li><a href='http://coderstalk.blogspot.com/2009/11/how-to-create-hyperlink-on-blogger.html' target='_blank'>How to Create Hyperlink on Blogger Header</a></li></ul></div><br /><br/><br /></span><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-317310975389938216?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com22tag:blogger.com,1999:blog-3928190665450830956.post-47132258719416572782008-04-02T09:08:00.010+08:002008-04-02T10:20:44.543+08:00Jeff Atwood starts war against Linux?<img style="float:left; margin:0 10px 10px 0;cursor:pointer; cursor:hand;" src="http://4.bp.blogspot.com/_QmenDvyMjlk/R_LluCMvaYI/AAAAAAAAAuo/AuGEXaCWLoA/s400/coding-horror-official-logo-small-greenscreen.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5184458700083915138" />I regularly visit <span style="font-weight:bold;">CodingHorror Blog</span> by Jeff Atwood... I love reading his posts and his readers comments. I feel like I'm in a coder's community who hang around listening and talking about what Jeff said.<br /><br />However, I don't know is it an April fool or it is for real where his posts on <a href="http://www.codinghorror.com/blog/archives/001089.html" target="_blank">Let That Be a Lesson To You, Son: Never Upgrade</a> is shockingly sounds like linux-bashing attempt:<br /><blockquote><br />"Apparently, Linux is so complex that even a world class software engineer can't always get it to work.<br /><br />I find it highly disturbing that a software engineer of Jamie's caliber would give up on upgrading software. Jamie lives and breathes Linux. It is his platform of choice. If he throws in the towel on Linux upgrades, then what possible hope do us mere mortals have? " —Jeff Atwood:CodingHorror <br /></blockquote><br />I laugh aloud when Jeff said, "Jamie Lives and breathes Linux." while this Jamie guy said that he installed Ubuntu 10.7.... Where did he get that Ubuntu 10.7? I don't know... <img class='inline' src='http://img458.imageshack.us/img458/1977/tongue2fe6.gif'/><br /> <br />Even thou I personally love linux and <a href="http://coderstalk.blogspot.com/2008/03/libraries-pc-can-use-ubuntu.html" target="_blank">promote everyone to give it a try on linux</a>, I don't wanna be bias to say that linux is way better than windows and OSX.

You can try any OS yourself and choose which is good for you.<br /><br />By the way, the new shiny <span style="font-weight:bold;">Ubuntu 8.04 (hardy Heron)</span> will be officially launched on 24th April 2008. You can freely download the CD at <a href="http://www.ubuntu.com" target="_blank">Ubuntu Website</a>. Ubuntu is getting better and better. Even I have dual booted my laptop, I haven't booted to my windows about 5 months now and I'm happy doing everything in Ubuntu. Even video editing on it. Or, if you still isn't convinced that ubuntu will run smoothly on your PC, just download the LiveCD and boot to Ubuntu without installing it on your PC. Give it a try and enjoy!!. <img class='inline' src='http://img458.imageshack.us/img458/6599/sengih2ys5.gif'/><br /><br/><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-4713225871941657278?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com0tag:blogger.com,1999:blog-3928190665450830956.post-19248438194022913572008-03-31T08:42:00.010+08:002008-06-12T19:04:20.316+08:00Installing rar and unrar programs in Linux or UnixI recently notice that I got some visitors bump in this <a href="http://coderstalk.blogspot.com">coder's talk blog</a>, searching for <a href="http://coderstalk.blogspot.com/2008/03/create-and-extract-rar-files-in-linux.html" target="_blank">How to create and extract rar files in linux</a> and I do remember that I didn't put on how to install rar and unrar program in other distributions of linux. I'm so sorry, my mistake. <img class='inline' src='http://coderstalk.googlepages.com/tongue.gif'/><br /><br />However, I am a linux supporter and I don't want to make you upset while bumping into this blog and didn't really get what you need. So, here is how to install rar and unrar on other linux distributions...<br /><br />Under Debian Linux, you can use the same apt-get method as follows to install unrar program:<br /><pre id="linuxterm">$ <span style="font-weight:bold;">apt-get install unrar</span></pre><br />If you are using Fedora core Linux then use yum command as follows:<br /><pre id="linuxterm">$ <span style="font-weight:bold;">yum install unrar</span></pre><br />If you are using FreeBSD, you can use:<br /><pre id="linuxterm">$ <span style="font-weight:bold;">pkg_add -v -r unrar</span></pre><br />If any of above, methods is not working, you can download binary package from <a href="http://www.rarlab.com/download.htm">official rarlab site</a> and choose the right package for your machine... for example, i chose the latest (by the time i write this post):<br /><pre id="linuxterm">$ <span style="font-weight:bold;">cd /tmp</span><br />$ <span style="font-weight:bold;">wget http://www.rarlab.com/rar/rarlinux-3.7.1.tar.gz</span></pre><br />then untar the file:<br /><pre id="linuxterm">$ <span style="font-weight:bold;">tar -zxvf rarlinux-3.7.1.tar.gz</span></pre><br />Both rar and unrar commands are located in rar sub-directory. Just go to rar directory:<br /><pre id="linuxterm">$ <span style="font-weight:bold;">cd rar</span><br />$ <span style="font-weight:bold;">./unrar</span></pre><br />Now copy rar and unrar to /bin directory:<br /><pre id="linuxterm">$ <span style="font-weight:bold;">cp rar unrar /bin</span></pre><br />Then you can use the same method on <a href="http://coderstalk.blogspot.com/2008/03/create-and-extract-rar-files-in-linux.html" target="_blank">creating and extracting rar files in linux</a> in my previous post.<br /><br />Another thing to add, you can also test the integrity of archive, with this command:<br /><pre id="linuxterm">$ <span style="font-weight:bold;">unrar t filename.rar</span> </pre><br />or list the files inside the rar file using this command:<br /><pre id="linuxterm">$ <span style="font-weight:bold;">unrar l filename.rar</span></pre><br />that's it... hope it helps... <img class='inline' src='http://coderstalk.googlepages.com/sengih.gif'/><br /><br/><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-1924843819402291357?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com3tag:blogger.com,1999:blog-3928190665450830956.post-63606915855018914932008-03-31T01:57:00.003+08:002008-03-31T02:10:59.168+08:00Libraries PC can use UbuntuDo you know that you can install Ubuntu as your <span style="font-weight:bold;">library's PC Operating System</span>.

Have you ever failed to renew your domain before it expires? This simple domain-check script maybe your life saver. Originally, it was written by <a href="http://prefetch.net/" target="_blank">Ryan Matteson</a>. Then <a href="http://www.cyberciti.biz/tips/domain-check-script.html" target="_blank">Vivek Gite</a> add up support to .org, .in, .biz and .info domain names.<br /><br />And now, I've updated the domain-check script to support Malaysia (.my) domain. I should call this <span style="font-weight:bold;">DNS Domain Expiration Checker Version 1.6</span> <img class='inline' src='http://img458.imageshack.us/img458/6599/sengih2ys5.gif'/><br /><br />In order to use the script, you can simply <a href="http://coderstalk.googlepages.com/domain-check.txt">download the script</a> and rename it to <span style="font-weight:bold;">domain-check</span>. Then <code>chmod +x</code> to be able to execute it. You can run it to parse a list of domain in a text file and send an email alert to you for any domain that about to expire. <br /><br />Command line code to download:<br /><br /><code>$ <span style="font-weight:bold;">wget http://coderstalk.googlepages.com/domain-check.txt -O domain-check</span></code><br /><br />Sample Usage: (in directory where you place the script)<br /><br /><pre><code>apogee@apogee-persiasys:~$ <span style="font-weight:bold;">./domain-check -d google.com.my</span><br /><br />Domain Registrar Status Expires Days Left<br />----------------------------------- ----------------- -------- ----------- ---------<br />google.com.my RGA000733 Valid 31-JUL-2008 134 <br /><br />apogee@apogee-persiasys:~$ <br /></code></pre><code><span style="font-style:italic;">[Note: you can place this on your "sbin" directory and run without "./" ]</span></code><br /><br /><center><img src="http://lh3.google.com/jerungkun/R-DxLVv9iYI/AAAAAAAAAug/KCCrrY2hWrc/s400/domain-check.png" /></center><br /><br />You can also get an email if google.com.my going to expire in 30 days:<br /><br /><code>$ <span style="font-weight:bold;">domain-check -a -d google.com.my -q -x 30 -e apogee@mailserver.com</span></code><br /><br />I would like to dedicate this updated script to <a href="http://blog.myfenris.net/" target="_blank">fenris</a> for having lot of domain to manage hehehe... <img class='inline' src='http://img458.imageshack.us/img458/1977/tongue2fe6.gif'/> Hope it help you dude!!

We share mp3 files within our same interest in music. As I'm now a <span style="font-weight:bold;">total Linux desktop user</span> (I didn't use windows anymore <img class='inline' src='http://img458.imageshack.us/img458/1977/tongue2fe6.gif'/> ), I have to find way to create and extract RAR files in Linux since we share the files in compressed RAR files in less than 5MB split.<br /><br />I always think that my findings in my Linux journey can also help others... So, here is the way to <span style="font-weight:bold;">create RAR file in Ubuntu Linux</span>. <br /><br />First, make sure you have already install unrar and rar which you can get it by issuing this command in your terminal (<span style="font-weight:bold;">Application > Accessories > Terminal</span>) ...<br /><br /><code>$ <span style="font-weight:bold;">sudo apt-get install rar unrar</span></code><br /><br /><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://lh6.google.com/jerungkun/R9YSYDpTQdI/AAAAAAAAArw/ba37grFhXTY/s400/apt-get-rar-unrar.png" /><br />In order to create RAR file, you can just right click on the selected files and click on "Create Archive...", select .rar on the archive dropdown and click on "Create". But, if you wanna extra control, you can use your great powerful terminal to do so. Here's what I do to Create a RAR file splitted to less than 5MB parts...<br /><br />Open up your terminal and <code>cd</code> to directory with your file to RAR and split. As it is on my <code>/home/apogee/Music</code> directory, I'm going there to find my files. <span style="font-style:italic;"><code>[Note: just type the command in bold without the dollar sign]</code></span><br /><br /><code>$ <span style="font-weight:bold;">cd /home/apogee/Music<br />$ ls -lh *.mp3</span><br />-rw-r--r-- 1 apogee apogee 6.7M 2008-03-10 16:21 Senandung-malam.mp3<br /></code><br />then I issue this command to create RAR file containing this mp3 file. I want each part to be less than 4MB...<br /><br /><code>$ <span style="font-weight:bold;">rar a -v4000k Senandung-malam.mp3.rar Senandung-malam.mp3 </span><br />RAR 3.70 beta 1 Copyright (c) 1993-2007 Alexander Roshal 8 Jan 2007<br />Shareware version Type RAR -? for help<br /><br />Evaluation copy. Please register.<br /><br />Creating archive Senandung-malam.mp3.rar<br /><br />Adding Senandung-malam.mp3 <br />Calculating the control sum <br /><br />Creating archive Senandung-malam.mp3.part2.rar<br /><br />... Senandung-malam.mp3 OK <br />Calculating the control sum <br />Done<br />$ </code><br /><br />Now I have two parts of rar files. Extracting these files should be more simpler on GUI. Check it out on my previous post on <a href="http://coderstalk.blogspot.com/2008/02/extracting-rar-files-in-ubuntu.html">How to Extract RAR files in Ubuntu Linux</a>. In case of many parts, just right click on the first part and choose extract here.<br /><br />In order to do it in your terminal, just issue this command...<br /><br /><code>$ <span style="font-weight:bold;">unrar e Senandung-malam.mp3.part1.rar .</span></code> <br /><br />The program will find for the continuous parts and extract the file. That's all.. Hope it helps you...

I haven't opened Rhythmbox Music Player in my office PC since I don't have any speaker here<img class='inline' src='http://img458.imageshack.us/img458/1977/tongue2fe6.gif'/>... After grabbing my mate's headphone, I noticed my Rhythmbox Music Player don't have mp3 support yet but I can play them well in VLC media player anyway. <br /><br />Yes, by default, there is no mp3 support in <span style="font-weight:bold;">Rhythmbox Music Player</span> in <span style="font-weight:bold;">Ubuntu Gutsy Gibbon 7.10</span>. If you search in google, you can find some blogs saying you can install gstreamer-0.8-plugins. However, when you type them on your terminal, you'll find out that the package isn't there anymore... Don't panic, you just have to install something else in gstreamer package. My lucky day maybe, I choose the right package in my first try without further reading about it... here's what I do...<br /><br />I typed..<br /><code>apogee@apogee-persiasys:~$ <span style="font-weight:bold;">sudo apt-get install gstreamer</span></code><br /><br />then press TAB twice, and the list come out...<br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://1.bp.blogspot.com/_QmenDvyMjlk/R9T6TzpTQcI/AAAAAAAAArQ/AH_yYbe6g_g/s1600-h/Screenshot-installgstreamer.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://1.bp.blogspot.com/_QmenDvyMjlk/R9T6TzpTQcI/AAAAAAAAArQ/AH_yYbe6g_g/s400/Screenshot-installgstreamer.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5176037089943437762" /></a><br />So I choose to install the one that have mp3 in its name... <br /><br /><code>apogee@apogee-persiasys:~$ <span style="font-weight:bold;">sudo apt-get install gstreamer0.10-fluendo-mp3</span></code><br /> <br />everything installed smoothly... So, I grabbed my Rhythmbox Music Player in the desktop, select my newly downloaded mp3 files in the folder and drag it to my Rhythmbox Music Player... Now my Rhythmbox can play mp3.. heheh... time to download more Keroncong mp3s hahahaha...<img class='inline' src='http://img458.imageshack.us/img458/6599/sengih2ys5.gif'/> Enjoy!!<br /><br/><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-5018671141379406489?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com0tag:blogger.com,1999:blog-3928190665450830956.post-6218157288201205842008-03-10T12:23:00.006+08:002008-03-10T14:57:27.832+08:00Malay translation codeLong time ago, I've been interested in creating an application to <span style="font-weight:bold;">translate English to Malay, and Malay to English</span>. However, up until now, I'm still here, sitting with nothing comes out of my tiny little brain. No single code... <br /><br />Hopefully, if I have time to spent on this "personal" non-profit project, I want to share it with all of you. Maybe I'll create a page like <span style="font-weight:bold;">Babel Fish</span> or <span style="font-weight:bold;">Google Translate</span> to help you in translating English phrase or website to Malay and vice versa. <br /><br /><a onblur="try {parent.deselectBloggerImageGracefully();} catch(e) {}" href="http://3.bp.blogspot.com/_QmenDvyMjlk/R9TbqTpTQbI/AAAAAAAAArI/5dDwQx8hOcc/s1600-h/translate-en-malay.png"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://3.bp.blogspot.com/_QmenDvyMjlk/R9TbqTpTQbI/AAAAAAAAArI/5dDwQx8hOcc/s400/translate-en-malay.png" border="0" alt=""id="BLOGGER_PHOTO_ID_5176003391630033330" /></a><br /><span style="font-weight:bold;">Babel Fish</span> is using <span style="font-weight:bold;">SYSTRAN</span>, while <span style="font-weight:bold;">Google Translate</span> use their own translation software. I always interested in what google is doing, because maybe I'm crazy about how google have done in revolutionize this information technology world as we already know. Many thanks to people in google for helping me out with this FREE technology. They make my self-learning journey become easier from day to day. Uh, I do get money from Google Adsense too...<br /><br />Back to the story, I did look after what technology lies behind Google Translate. As written in Wikipedia (another great internet revolution), Google Translate is based on an approach called statistical machine translation, and more specifically, on research by Franz-Josef Och who won the DARPA contest for speed machine translation in 2003. Och is now the head of Google's machine translation department.<br /><br /><span style="font-weight:bold;">Statistical Machine Translation(SMT)</span> is a machine translation paradigm where translations are generated on the basis of statistical models whose parameters are derived from the analysis of bilingual text corpora. The statistical approach contrasts with the rule-based approaches to machine translation as well as with example-based machine translation.<br /><br />Still, I haven't got any idea on how can I create my own <span style="font-weight:bold;">English to Malay Translator</span>.

It's really great to share it with you. before you talk back to me, please note that this is not a so called 'paid article' for them... I'm sharing this for free.

What's wrong?Today, I notice something wrong with my pagerank at one of my scrap blog, <a href="http://jerungkun.blogspot.com" target="_blank">The Rojak Blog</a>. As a loyal Firefox user, I also use google toolbar to access my google bookmarks and I do wanna know pagerank of certain page because I'm also google's loyal fan... heheh <img class='inline' src='http://img458.imageshack.us/img458/1977/tongue2fe6.gif'/><br /><br />Then, what's wrong with the code anyway? I see my pagerank icon on the blog from http://pr.blogflux.com/ shows zero (0/10) while my google toolbar shows 3/10. Which one do you think is more accurate? Obviously, the toolbar is from google and the pagerank value is also from google.<br /><br /><a href="http://jerungkun.blogspot.com/" target="blank"><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer; cursor:hand;" src="http://2.bp.blogspot.com/_QmenDvyMjlk/R83xwstIt9I/AAAAAAAAApY/ZxXsRPJDnrU/s400/rojak-blog.png" border="0" alt="the rojak blog" id="BLOGGER_PHOTO_ID_5174057365855057874" /></a><br /><span style="font-weight:bold;">The Verification...</span><br /><br />So, I go to pr.blogflux.com to verify the rank and blogflux still says that the pagerank of http://jerungkun.blogspot.com is 0/10. Then I go to another pagerank checker page at http://www.prchecker.info and it says 3/10 for that same <a href="http://jerungkun.blogspot.com" target="_blank">scrap blog</a>. Now, I can verify that there might be something wrong on pr.blogflux. Maybe they have to fix their code to keep people link to their site.<br /><br /><span style="font-weight:bold;">The Solution...</span><br /><br />Instead of emailing pr.blogflux and told them that their <span style="font-weight:bold;">pagerank checker code</span> is wrong, I took a quick solution which is to just change my prchecker. I get it from <a href="http://www.prchecker.info/pagerank-check-button.php" target="_blank">www.prchecker.info</a>. Pretty simple right? bye-bye blogflux...<img class='inline' src='http://img458.imageshack.us/img458/6599/sengih2ys5.gif'/><br /><br/><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-6077931543845731385?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com0tag:blogger.com,1999:blog-3928190665450830956.post-65441854237876407542008-03-02T01:09:00.007+08:002010-02-11T11:02:34.298+08:00XSS on maxgames.comI got bored tonite... found and try these (actually noted by a friend)...

I decided to switch the serial console to the second port which is /dev/ttyAM1 because I'm going to use the first serial /dev/ttyAM0 for my Wavecom GPRS modem. So, I open the /etc/inittab and just realize that serial console on /dev/ttyAM1 is already there.<br /><br />Then I grab my RS-232 cable and plug it from my /dev/ttyS0 on my PC to the /dev/ttyAM1 on the TS-ARM board... after waiting for some seconds, my minicom shows the login... <br /><code><br />Debian GNU/Linux 3.1 ts7000 ttyAM1<br /><br />ts7000 login: <br /></code><br /><br />So, I type root and press the enter... the console returns, "Login incorrect"... WTF!!<br /><br />How come the serial console on the second port is useless for root? The solution for this is actually very simple. But it took me some minutes to figure it out... hehehe...<img class='inline' src='http://img458.imageshack.us/img458/1977/tongue2fe6.gif'/><br /><br />Thank god, i've already fixed the ssh, so i can ssh to the board...<br /><code><br />$ ssh root@10.1.1.91<br />$ Password:<br /></code><br /><br />The solution is, edit the /etc/securetty file...<br /><code><br />$ vi /etc/securetty<br /></code><br />And then add the line ttyAM1 under the ttyAM0 in the /etc/securetty file... press escape and type :wq<br /><br />That's it. Reboot the board. and now i can login with root on my second serial console. Thanks to the guys in #debian at freenode for pointing me to the right direction. <img class='inline' src='http://img458.imageshack.us/img458/6599/sengih2ys5.gif'/><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-6414318365534647676?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com1tag:blogger.com,1999:blog-3928190665450830956.post-57921516324069999732008-02-26T12:21:00.004+08:002008-02-26T12:46:41.626+08:00Speed Up your Internet Speed in UbuntuDid you know that you can boost up your internet speed in Ubuntu Gutsy Gibbon 7.10 by some simple changes in a test file?

As one of rapidshare fan, I always found the shared files are in RAR format. So, if you are Ubuntu Gutsy user like me, you may notice that unrar (the program to open RAR files) is not installed by default.<br /><br />No Problem... you can simply install it in less than a minute. Open up your Terminal (Application > Accessories > Terminal ) and issue this command:<br /><code><br />$ sudo apt-get install unrar<br /></code><br />Then after it is installed, you can now right click on the file and click on Extract Here. Isn't it simple? <img class='inline' src='http://img458.imageshack.us/img458/6599/sengih2ys5.gif'/><br /><br /><img src="http://lh6.google.com/jerungkun/R8JJjm1lp4I/AAAAAAAAAj8/rYD3L3aJimw/s800/extract-rar-ubuntu.png" /><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-278510133727949402?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com0tag:blogger.com,1999:blog-3928190665450830956.post-47084714699517359362008-02-22T10:57:00.007+08:002008-02-25T11:36:34.882+08:00Installing Microsoft Fonts in UbuntuYou may want to install Microsoft Truetype fonts in Ubuntu for any reason. It's very simple. All you need to do in your <span style="font-weight:bold;">Ubuntu</span> Gutsy Gibbon 7.10 is to install the <span style="font-weight:bold;">msttcorefonts</span> package.<br /><br /><img src="http://lh6.google.com/jerungkun/R8I3Dm1lp2I/AAAAAAAAAjs/yYCrUOMPfyg/s800/ubuntu-microsoft-fonts.png" /><br /><br />The Truetype Microsoft fonts provided by the package include:<ul><li>Andale Mono</li><li>Arial Black</li><li>Arial (Bold, Italic, Bold Italic)</li><li>Comic Sans MS (Bold)</li><li>Courier New (Bold, Italic, Bold Italic)</li><li>Georgia (Bold, Italic, Bold Italic)</li><li>Impact</li><li>Times New Roman (Bold, Italic, Bold Italic)</li><li>Trebuchet (Bold, Italic, Bold Italic)</li><li>Verdana (Bold, Italic, Bold Italic)</li><li>Webdings</li></ul>To install msttcorefonts package, open a Terminal... <b><i>Application > Accessories > Terminal</i></b> and type (without the dollar sign):<br /><code><br />$ sudo apt-get install msttcorefonts<br /></code><br />After doing this, you can also install other TTF fonts in your collection by copying them in your <b><i>~/.fonts</i></b> folder. After installing new fonts, you will have to log out and log in again to be able to see and use the new fonts. If you want to avoid this, you can regenerate the fonts cache by issuing the following command:<br /><code><br />$ sudo fc-cache -fv<br /></code><br />That's all.

Previously, I've been struggling to run linux on my laptop. I tried Red Hat, Fedora, Mandrake... but they are not stable in my old laptop. Until I found Ubuntu... Now, I'm really satisfied to settle down with this great, easy to use and pretty stable open source Operating System for my laptop. So, I have <span style="font-weight:bold;">Ubuntu Gutsy Gibbon 7.10</span> on my lappy now and I thought I'll forget windows soon... <img class='inline' src='http://img458.imageshack.us/img458/1977/tongue2fe6.gif'/><br /><br />Normally, people start learning programming with some simple typical <span style="font-weight:bold;">Hello World</span> sample. However, I'm searching for some challenge as my first try. So, I pick <span style="font-weight:bold;">linux socket programming</span> as my quick start. During my short journey on the web, I found this simple <a href="http://linuxgazette.net/issue74/tougher.html" target="_blank">tutorial by Rob Tougher</a>. Pretty cool and complete for my starting point... So, if you wanna try it too, feel free to get the code from Rob Tougher's tutorial page and compile it yourself. Modify the codes as you like and learn new things.<br /><br />While working on the codes downloaded from that page, I found errors while compiling it. Maybe Rob leave this error for us to learn... Anyway, don't worry mates, I'll share the answer... heheheh...<img class='inline' src='http://img458.imageshack.us/img458/6599/sengih2ys5.gif'/><br /><br />Here's the error on my first try...<br /><code><br />apogee@apogee-laptop:~/C-codes/socketserver$ make<br />g++ -c -o ServerSocket.o ServerSocket.cpp<br />g++ -c -o Socket.o Socket.cpp<br />Socket.cpp: In member function ‘int Socket::recv(std::string&) const’:<br />Socket.cpp:135: error: ‘cout’ is not a member of ‘std’<br />make: *** [Socket.o] Error 1<br />apogee@apogee-laptop:~/C-codes/socketserver$ <br /></code><br /><br />g++ returns this error not because there is no <span style="font-weight:bold;">'cout'</span> in <span style="font-weight:bold;">std</span>. But, because we didn't properly declare the <span style="font-weight:bold;">std</span> to use <span style="font-weight:bold;">'cout'</span>. In order to fix this, I just add this line...<code>#include <iostream></code> in Socket.cpp (you can place it on top, just after all <code>#include</code> codes) and try to <span style="font-weight:bold;">'make'</span> again. I'm sure this error will disappear.<br /><br />Then, here's the second 'make' trial...<br /><code><br />apogee@apogee-laptop:~/C-codes/socketserver$ make<br />g++ -c -o Socket.o Socket.cpp<br />g++ -c -o simple_server_main.o simple_server_main.cpp<br />simple_server_main.cpp: In function ‘int main(int, int*)’:<br />simple_server_main.cpp:7: error: ‘cout’ is not a member of ‘std’<br />simple_server_main.cpp:35: error: ‘cout’ is not a member of ‘std’<br />make: *** [simple_server_main.o] Error 1<br />apogee@apogee-laptop:~/C-codes/socketserver$ <br /></code><br /><br />Ups... still got the error... <img class='inline' src='http://img458.imageshack.us/img458/1977/tongue2fe6.gif'/> but this time, it is in simple_server_main.cpp... No problem, let's do the same on this file too... save them and here is the third 'make' trial...<br /><code><br />apogee@apogee-laptop:~/C-codes/socketserver$ make<br />g++ -c -o simple_server_main.o simple_server_main.cpp<br />g++ -o simple_server ServerSocket.o Socket.o simple_server_main.o<br />g++ -c -o ClientSocket.o ClientSocket.cpp<br />g++ -c -o simple_client_main.o simple_client_main.cpp<br />g++ -o simple_client ClientSocket.o Socket.o simple_client_main.o<br />apogee@apogee-laptop:~/C-codes/socketserver$ <br /></code><br /><br />SUCCESS!!! without errors anymore... And now, time for testing... open up a terminal and you will see this output when you type <code>./simple_server</code><br /><code><br />apogee@apogee-laptop:~/C-codes/socketserver$ ./simple_server <br />running....<br /></code><br /><br />Then open another terminal and run the simple client... I run it 3 times...<br /><code><br />apogee@apogee-laptop:~/C-codes/socketserver$ ./simple_client <br />We received this response from the server:<br />"Test message."<br />apogee@apogee-laptop:~/C-codes/socketserver$ ./simple_client <br />We received this response from the server:<br />"Test message."<br />apogee@apogee-laptop:~/C-codes/socketserver$ ./simple_client <br />We received this response from the server:<br />"Test message."<br />apogee@apogee-laptop:~/C-codes/socketserver$ <br /></code><br /><br />Now, I can start modifying the code to learn how it really works. Feel free to download my <a href="http://coderstalk.googlepages.com/simple-socket.tgz">'fixed version' of Rob Tougher's code</a>. You can simply untar it by issuing this command in your newly created project folder...<br /><code><br />prompt:~$ tar -zxvf simple-socket.tgz<br /></code><br /><br />Programming is fun! give it a try if you haven't tried once! Good luck!!<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-2990214309881586966?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com3tag:blogger.com,1999:blog-3928190665450830956.post-18311637690344507382007-09-30T15:08:00.000+08:002007-09-30T15:59:49.268+08:00VBScript to Replace Underscores in Filename with Spaces for All Files in a FolderSometimes I wanted to remove underscores in file name and replace it with space. For example I would like to see the filename as <span style="font-weight:bold;">'Sharifah Aini - Suasana Hari Raya.mp3'</span> instead of <span style="font-weight:bold;">'Sharifah_Aini_-_Suasana_Hari_Raya.mp3'</span>. I often have this kind of files when I download mp3s on the internet. I know this maybe so simple because you can just select the file in <span style="font-weight:bold;">Windows Explorer</span>, <span style="font-weight:bold;">Press F2</span> and manually rename the file. But for a collections of files in a folder, this may be a boring repetitive task that I'll hate to do. <br /><br />So, as a damn lazy coder <img class='inline' src='http://img458.imageshack.us/img458/1977/tongue2fe6.gif'/>, I've wrote a short Visual Basic Script to automatically do the task with only one simple command. I think this <span style="font-weight:bold;">VBScript</span> maybe useful for you too. So, I would like to share my VBScript to replace underscores in filename with spaces for all files within a folder. Here's the script...<br /><FONT COLOR="#000000"><TT><PRE><br /><FONT COLOR = "#008800">'========================================================<br />' VBScript to replace underscore in file name with space <br />' for each files in a folder<br />' Written by ApOgEE of http://coderstalk.blogspot.com<br />'========================================================<br /></FONT><FONT COLOR = "#000088">Dim </FONT>sName<br /><FONT COLOR = "#000088">Dim </FONT>fso<br /><FONT COLOR = "#000088">Dim </FONT>fol<br /><br /><FONT COLOR = "#008800">' create the filesystem object<br /></FONT><FONT COLOR = "#000088">Set </FONT>fso = WScript.CreateObject("Scripting.FileSystemObject")<br /> <br /><FONT COLOR = "#008800">' get current folder<br /></FONT><FONT COLOR = "#000088">Set </FONT>fol = fso.GetFolder(".")<br /><br /><FONT COLOR = "#008800">' go thru each files in the folder<br /></FONT><FONT COLOR = "#000088">For Each </FONT>fil <FONT COLOR = "#000088">In </FONT>fol.Files<br /> <FONT COLOR = "#008800">' check if the file name contains underscore<br /></FONT> <FONT COLOR = "#000088">If </FONT>InStr(1, fil.Name, "_") <> 0 <FONT COLOR = "#000088">Then<br /></FONT> <FONT COLOR = "#008800">' replace underscore with space<br /></FONT> sName = Replace(fil.Name, "_", " ")<br /> <FONT COLOR = "#008800">' rename the file<br /></FONT> fil.Name = sName<br /> <FONT COLOR = "#000088">End If<br />Next<br /></FONT><br /><FONT COLOR = "#008800">' echo the job is completed<br /></FONT>WScript.Echo "Completed!"<br /></FONT></PRE></TT><br />To use the script, you just need to copy this scripts to a text file and then name the textfile with <span style="font-weight:bold;">'rmus.vbs'</span> or any other name you like with <span style="font-weight:bold;">'.vbs'</span> extension which is for vbscript.<br /><br />There is lots of ways to use the script. One of them is, copy the .vbs file to the folder you want the task to be done and then double click the .vbs file in that folder. When the script is done, it will prompt you with a message box which says <span style="font-weight:bold;">'Completed!'</span>. I'll post the other ways to run this kind of scripts later.

Check out <span style="font-weight:bold;">Microsoft</span> article about <a href="http://msdn2.microsoft.com/en-us/library/a1y8b3b3(vs.80).aspx">Collections in Visual Basic</a><br /><h4>Creating Collection Class using VB Class Builder</h4>The simplest way to create collection class is by using the VB Class Builder. Here's the simple step:<ul><li>Right click on the <span style="font-weight:bold;">Project Explorer</span> area</li><li>Select <span style="font-weight:bold;">Add > Class Module</span></li><li>Select <span style="font-weight:bold;">VB Class Builder</span>, and click <span style="font-weight:bold;">Open</span></li><li>Select <span style="font-weight:bold;">File > New > Collection</span> and Set your class to be grouped it the Collection Class, Set The collection Name and click <span style="font-weight:bold;">OK</span></li><li><span style="font-weight:bold;">Update Project</span> and Close the Builder</li></ul><br />Notice, you will have one new class based on the name you set on the Builder. Open the code window for the New Collection Class and you will notice there is no CheckExists function to check whether the key associated to an object it the collection is already exists or not.<br /><br />Here is my function code to check if an object exists in a collection object<br /><FONT COLOR="#000000"><TT><PRE><FONT COLOR = "#000088">Public Function </FONT>CheckExists(vntIndexKey <FONT COLOR = "#000088">As Variant</FONT>) <FONT COLOR = "#000088">As Boolean<br /></FONT> <FONT COLOR = "#000088">On Error Resume Next<br /></FONT> <FONT COLOR = "#000088">Dim </FONT>cObj <FONT COLOR = "#000088">As Object<br /></FONT> <br /> <FONT COLOR = "#008800">' just get the object<br /></FONT> <FONT COLOR = "#000088">Set </FONT>cObj = mCol(vntIndexKey)<br /> <br /> <FONT COLOR = "#008800">' here's the key!

Usually, you’ll try to use the Mark and Copy commands on the command prompt’s Edit menu. I recently found an article from <b>Tech Republic</b> about <b>Copy and paste from Windows XP Pro’s command prompt straight to the Clipboard</b> where <b>Greg Shultz</b> is introducing a command line tool called Clip.exe. But I have my own way to get information from a command prompt and onto your notepad without using the Clip.exe.<br /><br />It is so simple. Lets say, you want to get the output from ipconfig command, then just add a '>' and type the name of text file you want like 'ipconf.txt'. On the command prompt it will look like this:<br /><br /><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer;" src="http://lh6.google.com/jerungkun/RvIwKNsD4MI/AAAAAAAAAc4/EplkAlvGJVI/s800/ipconf.JPG" border="0" alt="" /><br />Then, you can view your output on notepad by simply type 'notepad ipconf.txt' and press enter like this:<br /><br /><img style="display:block; margin:0px auto 10px; text-align:center;cursor:pointer;" src="http://lh3.google.com/jerungkun/RvIyidsD4NI/AAAAAAAAAdA/c8Lh5J3USWA/s800/npad.JPG" border="0" alt="" /><br />That's all.

But that’s what I’m currently doing. And that’s also why sometimes I have to leave this blog untouched without an updates. However, I’m trying to keep this blog alive and now I’m planning to share my understanding in subjects taken through my degree courses which I think may be helpful for those who are interested about <span style="font-weight:bold;">Computer Science</span> on this <span style="font-weight:bold;">Coder’s Talk Blog</span>.<br /><br />This semester, I’m taking three subjects which were <span style="font-weight:bold;">Accounting Information System (SCM4253), Office Automation (SCM4213) and Strategic Management and Information System (SCM3153)</span>. So this time, I will blog about this three subjects until the end of semester. So stay tune with this blog and we will soon discover and understand these three subjects in the adventure to discover <span style="font-weight:bold;">the Science of Computer</span>.<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-7931816504108111211?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com1tag:blogger.com,1999:blog-3928190665450830956.post-53410120753584717052007-07-26T17:05:00.000+08:002007-07-26T18:02:18.770+08:00How to Redirect Using PHP<img src='http://img222.imageshack.us/img222/6343/phpug8.jpg' style='float:left;margin:0 10px 0 0;' alt='PHP'>A simple PHP script could be use to redirect visitor from the page they entered to a different web page. There is lot of reason you may want to do this including:<br /><div style='padding-left:150px;'><ul><li>You may have links that is no longer exists in your domain</li><li>You don't want anybody to browse your parent directory where you don't have any index page in it</li><li>Or maybe you may want to shorten your long url like TinyUrl.</li></ul></div><br />Using this simple method, they can be seamlessly transfered to the new page without having to click a link to continue.<br /><br /><span style="font-weight:bold;">Why use PHP for redirecting?</span><br />Here's some reason on why we are using PHP for redirecting.<br /><ul><li>Users are redirected quickly and seamlessly</li><li>When using the 'Back' button, the user is taken to the last viewed page, not the redirect page</li><li>Works on all browsers</li></ul>However, you have to make sure that your web host do support PHP in order to do this.<br /><br />In this example, assuming Mikey want to redirect his visitor who go to his domain http://mikey.com to his blog Url which is at http://mikey.com/blog. What mikey have to do is simply create a text file in his parent folder and type this:<br /><br /><div style="padding: 10px; width: 80%; background-color: rgb(238, 238, 238);"><code><?php<br />header( 'Location: http://mikey.com/blog' ) ;<br />?><br /></code></div><br />Then save the file as 'index.php'. Now, all visitors who go to http://mikey.com will be seamlessly redirected to http://mikey.com/blog. Isn't it easy? Enjoy programming and have fun!<br /><br/><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/3928190665450830956-5341012075358471705?l=coderstalk.blogspot.com' alt='' /></div>ApOgEEhttp://www.blogger.com/profile/10350138531363117428noreply@blogger.com0tag:blogger.com,1999:blog-3928190665450830956.post-35401998860739464032007-07-12T18:06:00.003+08:002010-02-11T11:08:24.645+08:00How to Show and Hide Text in Blog PostI would like to share on how to make a Show/Hide text in your blog post. I'm sorry if I didn't explain detail enough because I want to keep my post short as I'm in a hurry. However, you can read the detail explanation on <a href="http://help.blogger.com/bin/answer.py?answer=42214&topic=8932" target="_blank">Blogger Help</a>.<br /><br />In this example, I assume you have sub topics that you want to make it hidden until reader clicks on the headline. Without the show/hide trick, it would look like this...<br /><br /><div style="width:80%;background-color:#EEEEEE;padding:10px;"><h4>Title One</h4>This is the example text for title one.<br /><h4>Title Two</h4>This is the example text for title two.<br /><h4>Title Three</h4>This is the example text for title three.<br /></div><br />Here's my step to do this... Firstly, edit your template and add the following code in the CSS area.<br /><br /><div style="width:80%;background-color:#EEEEEE;padding:10px;"><code><br />.posthidden {display:none}<br />.postshown {display:inline}<br /></code></div><br />Then add the following javascript code on your blog template between the <code><head></head></code> tag.<br /><br /><div style="width:80%;background-color:#EEEEEE;padding:10px;"><pre><script type="text/Javascript"> <br /><br />function expandcollapse (postid) { <br /><br /> whichpost = document.getElementById(postid); <br /> <br /> if (whichpost.className=="postshown") { <br /> whichpost.className="posthidden"; <br /> } <br /> else { <br /> whichpost.className="postshown"; <br /> } <br />} <br /></script><br /></pre></div><br />Now save your template and all you have to do in each post you want to have the expandable sub topic is to create unique id for each sub topics where the code will look like this:<br /><br /><div style="width:80%;background-color:#EEEEEE;padding:10px;"><pre><a href="javascript:expandcollapse('subtopic0001')"><br /><h4>Title One</h4></a><br /><span class="posthidden" id="subtopic0001"><br />This is the example text for title one.</span><br /><br /><a href="javascript:expandcollapse('subtopic0002')"><br /><h4>Title Two</h4></a><br /><span class="posthidden" id="subtopic0002"><br />This is the example text for title two.</span><br /><br /><a href="javascript:expandcollapse('subtopic0003')"><br /><h4>Title Three</h4></a><br /><span class="posthidden" id="subtopic0003"><br />This is the example text for title three.</span><br /></pre></div><br />And, here's the result...<br /><br /><div style="width:80%;background-color:#EEEEEE;padding:10px;"><a href="javascript:expandcollapse('subtopic0001')"><h4>Title One</h4></a><span class="posthidden" id="subtopic0001">This is the example text for title one. The long text is just an example that this area will automatically move the space down. Subscribe to coderstalk.blogspot.com for more free code from me. Or simply check me out for latest update soon.</span><br /><a href="javascript:expandcollapse('subtopic0002')"><h4>Title Two</h4></a><span class="posthidden" id="subtopic0002">This is the example text for title two. Come on my friend, you can even hide images in here. Look at this...<br /><center><a href="http://img157.imageshack.us/my.php?image=avatar9xp.gif" target="_blank"><img src='http://img157.imageshack.us/img157/5549/avatar9xp.gif' alt='ApOgEE Avatar' title='ApOgEE'></a></center></span><br /><a href="javascript:expandcollapse('subtopic0003')"><h4>Title Three</h4></a><span class="posthidden" id="subtopic0003">This is the example text for title three.</span><br /></div><br />That's all...
