I’ve taken this little piece of code around the Web (sorry, I forgot the original source) and it’s a good example on how to develop a plugin for jQuery:
/** Usage:
* $.random(int);
* $.randomBetween(min, max); */
jQuery.extend({
random: function(X) {
return Math.floor(X * (Math.random() % 1));
},
randomBetween: function(MinV, MaxV) {
return MinV + jQuery.random(MaxV - MinV + 1);
}
});

Here it is a small view to see all triggers stored in the DBMS. IMHO it’s more usable than going into INFORMATION_SCHEMA database and browse TRIGGERS records.
CREATE VIEW `List_triggers` AS
SELECT `TRIGGER_NAME` AS `Name`, `TRIGGER_SCHEMA` AS `Database`,
`EVENT_OBJECT_TABLE` AS `Table`,
CONCAT_WS(" ", ACTION_TIMING, EVENT_MANIPULATION) AS `Action`
FROM `INFORMATION_SCHEMA`.`TRIGGERS`
As simple as:
gconftool-2 --shutdown
rm -rf ~/.gconf/apps/panel
pkill gnome-panel
If you want to restore, in example, Games menu from Applications, you have to:
cd ~/.config/menus
vim applications.menu
and then remove (in my case)
Deleted node:
<Menu>
<Name>Games</Name>
<Exclude>
<Filename>mahjongg.desktop</Filename>
</Exclude>
<AppDir>/home/chris/.local/share/applications</AppDir>
<!-- remove this node </Deleted> -->
</Menu>

I was disappointed when I figured out that Vuze didn’t work anymore after having upgraded to Lucid Lynx. So I launched the program in the shell and I discovered it couldn’t find some Swing stuff for creating the GUI.
Back to Java Sun 6, so:
chris@sirio:~$ sudo update-java-alternatives -l
java-6-openjdk 1061 /usr/lib/jvm/java-6-openjdk
java-6-sun 63 /usr/lib/jvm/java-6-sun
chris@sirio:~$ sudo update-java-alternatives -s java-6-sun
The development release of Chrome allow to install extension as for Firefox, but the process of installation (and even of creation as I heard from some developers) is faster.
Here it is my list:
function isValidEmail($email)
{
if(version_compare(PHP_VERSION, '5.2.0', '>=')
return filter_var($email, FILTER_VALIDATE_EMAIL);
else
return eregi('^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$', $email);
}
Regular expressions are a very powerful weapon for the developer if he can deals with all the pain of testing, debugging and learning the quirks of this matter.
I’m collecting some links to be red one day, when I’ll got time to dive more deeply in the argument:
