Alienware Arena

Alienware Arena was one of those projects that was a lot of fun to work on. Doing work inside the video game industry is always fun for me, especially since I enjoy a good video game now and then.


Restoring Large MySQL Dump - 900 Million Rows

This last weekend I had a fun opportunity of restoring roughly 912 Million Rows to a database. 902 Million belonged to one single table (902,966,645 rows, to be exact).

Sending Email from non-email Ubuntu Server

I have a couple of scripts that use the linux “mail” command to send results of cron jobs, backups, and such.

Using GIT with SVN

Over the last two and a half years, since the day I presented on Streamlined Web Development with SVN, I’ve been hearing about the Source Control Management tool called “git.” I kept reading about it online, seeing it on the schedules for conferences, and hearing it about it in the different Open Source groups here in Utah. I have been a big time Subversion (SVN) user for several years now, and it has solved my problems Background I have tried to use it in the past two or three times, but each time I had basically given up. There were a few reasons why in the past I didn’t really stick with using Git:
