github is becoming the most valuable open source tool. There are tons of open source over there. I believe that it might have surpassed sourceforge and may be google code.
Last week I tested a project called hiphop from facebook that compiles php into C, and then to binary executables. The project claims to achieve about 2-3 times speed improvement. Although that is a good improvement, yet it does not beat psyco, that can achieve 10 fold when compiling python.
It took me around an hour to compile hiphop. The main reason it requires to patch most of its dependencies before compiling them so it is not just the matter of installing the dependencies using synaptic or apt.
After I compiled it, I tried several simple examples and it was able to generate a standalone webserver application executable. Once the program is executed it can be ran once as a regular executable or you can run it as a web server that listens on a given port.
