2013-01-04 Annoying issue with PHP $_GET replacing the dots in variable names

The PHP replaces certain characters (among which dots, spaces, and square brakets) in the $_GET field names.
Personally I am strongly against pre-processing such information without a strong ground. The ground, the same with the well-known magic quotes workaround is to ameliorate the developer's life in using the parameters in a safer and easier way.
However, the effect is that in order to use any kind of variable name the developer needs to patch the patch.
The idea is that before using the $_GET variables they have to be corrected:

clear the old keys;
replace them with the correct key.

But now, another issue appeared in the PHP LightOpenID implementation, where the constructor strongly relies on this workaround.
Also this had to be fixed now.

2012-12-05 Google Chrome extension to dynamically manipulate pages

How to make a small ad-hoc extension that manipulates dynamically pages every time they get loaded.
Their utility might be (but not limited to) autologin, GUI augmentation, manipulation, reformatting.

Create a folder on disk (as an example, "E:\ChromePlugin\");
Create a manifest.json file;
Copy one JS utility (like jquery-1.8.2.js to the folder);
Add an icon file (let's call it icon.png) to the folder (check http://kb.sorescu.eu/article/121107093243/Great-PNG-transparent-icon-finder-site-http-www.iconfinder.com- to find nice icons);
Create the script file (let's call it script.js);
Add the extension: Google Chrome > Wrench > Extensions > tick the "Developer mode" > click "Load unpacked extension" and select the folder ("E:\ChromePlugin\");
Make available via HTTP (preferably HTTPS if you want to avoid some minor issues) the dynamic file (let's call it ChromeExtension.js);
Attention, the jquery-1.8.2.js script mentioned in the manifest.json file won't be available in the context of http://localhost:81/js/ChromeExtension.js.

The manifest.json file contents should be as in manifest.json

The script.js is file the script that is actually launched every time a page loads. The ChromeExtension.js file contents is as attached.

2012-12-05 Small utility that types unique values from keyboard just by a hot key stroke

A short utility that types the current time stamp from keyboard (anywhere on desktop). I developed it because I was bored on typing all the times unique values while testing applications.
Executing the program is simple:

start RunCS TypeTimeStamp.cs

This program does the following:

When pressing CTRL-INS, the application will type the date in YYMMDDHHmmss format;
When pressing CTRL-SHIFT-INS, the application will type the date in YYMMDDHHmmssqq format;
When pressing CTRL-SHIFT-ALT-INS, the application will quit;
