I started to find out about AJAX, a fashion Web technology, which stands for Asynchronous JavaScript And XML; Hatem’s blog helped me a lot, and the Internet is a huge source of information.
A “hello world” application is like the following: it requests data from page.php and writes the content between div tag identified by […]

A         a is an intern whom I am supposed to assist to fix her PHP code. The following case seems obvious; it’s nevertheless tricky.
 
- A         a: I have several checkboxes whose the number depends on the database rows. Once a user submits, checkboxes are displayed again, but the ones already checked must appear checked too.

Today seems to be Tom’s day in my blog!
Tom asked me some days ago whether I can contribute to the first Tunisian OpenSource project QCM-Gen 0.1, something I cannot refuse; however, I spent my free time watching Jackass the movie and playing chess. Finally I decided yesterday to work on it seriously (well, […]

I have released a 0.1 version of a pseudo WordPress plugin which displays events that occured in the same day / month along the history.
Pseudo, becuase it’s doesn’t have plugins features; I can even say it’s independent from WordPress. It consists of 2 MySQL tables: the main (wp_todayevents) and the backup one (wp_todayevents_archive) and […]

I don’t like the way of making permanent links in WordPress blogs; there are mainly 2 methods:

URL indicates date and/or title post, the most popular method, but the problem is funny: I can’t access to my posts through a proxy/firewall stupidly configured, where the words ’sex’, ‘fuck’, ’suck’, … are censored. As I don’t […]

Porn, viagra, casino, and some words I don’t understand… I got more than 70 within a week! Fortunately, the WordPress keywords filter removed most of them, but it’s not enough, since the database size strangely increased. I am using a new method: denying spam robots with .htaccess file.
According to the WordPress site, you should […]

WordPress contains a nice WYSIWYG HTML editor, but it doesn’t fit with XHTML specifications.
I found out a cool method to generate valid XHTML code on WordPress; all what you need is Nvu and Vim.
First, use Nvu to edit your HTML text, and set you markup output to XHTML transitional:
Tools - Preferences - Advanced - […]

This post is generated using a PHP code!
Thanks to Mr. R’s suggestion, I looked at the WordPress plugins repository and found a script that executes PHP.
Excellent feature, it even deals with forms inside posts and pages, and keeps it valid XHTML.

I released a cool PHP script that generates a wish card.
You can both use it and hack on it.
For users

A is for awk, which runs like a snail, and
B is for biff, which reads all your mail.
 
C is for cc, as hackers recall, while
D is for dd, the command that does all.
 
E is for emacs, which rebinds your keys, and
F is for fsck, which rebuilds your trees.
 
G is for grep, a clever detective, […]

A Perl script to integrate graphics into a HTML file.
Requires Perl with the following CPAN modules: HTML::TokeParser and MIME::Base64.
Handles HTML and XHTML documents, recognizes GIF, PNG and JPEG graphics, parses full path image files, compatible with standards.
See a live example (the documentation itself) here.
Click here to download the script.

Here’s a little script to display memory status and refresh it each 5 seconds. You need xmessage to run it:
while free -otm|xmessage -buttons “Close”:1,refresh:0 -default “close” -timeout 5 -file -;do :;done

I have coded a funny and buggy Feed Reader, with PHP and SQLite. So don’t be afraid if you see on the log a user-agent with a strange identity showing my URL: it means that I have added your RSS to my bookmarks

The following Perl program loops from 0 to 1 incrementing by 0.1:
perl -e ‘while ($_ < 1.0) { printf(”%.1f\n”,$_); $_+=0.1;}’

Wakegen dropped me that C program that crashes your UNIX machine.
Be careful! It’s dangerous, use it at your own risk
#include <sys/types.h>
#include <unistd.h>
int main() {
pid_t p=fork();
main();
}
It consists of the following: Creating infinte child processus until the buffer gets overloaded; […]
