A while back I decided to create a MMORPG (Massive Multiplayer Online Role Playing Game). It was created in PHP with MySQL database. The idea was to create something that would run in any browser without need of any extra plugins/addons.
I have been thinking about learning RegEx. It seems like you can cut down coding with the use of RedEx, i.e. extracting data from a string, replace data from string.
As good Windows 7 seems to be, it has its perks, at least on my Laptop. I installed both 32 and 64 bit version of Windows 7 on M720R, and it had driver problems, on both architectures. There were more problem on 64 bit then on 32 bit.
