GMail trick

That you may or may not know about. It's as simple as : foo.bar@gmail.com is equivalent to f.oobar@gmail.com is equivalent to foo.bar+some_random_string@gmail.com

Pretty handy when registering on websites (create one address per site and see who's guilty of spammer-fluffing for example).

Adobe Reader 9 on Windows 7

For all the people that might be having issues with the setup of Adobe Reader 9 on the beta version of Windows 7, try and set the compatibility mode to "Windows Vista" (download the Vista installer on Adobe's website).

That did the deed for me, hope it can be of help.

Tomboy Plugin development

One of the most annoying tasks for me in the process of creating my own Tomboy plugin has been the compilation process. Since the open source applications come with their source code (and some people still build their applications from source) and since the differences in libraries, platforms and whatnot make it real hard to build a project on every platform (be it C, C++ or even C# code), a tool called automake/autotools/autoconf was created (more information here) . The idea in itself would be brilliant if it wasn't for the overwhelming complexity of this tool.
