Yum on RHEL4
First off, apologies for not have posting anything in the last few weeks. I just got back from Manila, Philippines to visit my ill grandfather (read: father). He made it, but is still weak. I love you lolo! Anyway, I personally run Red Hat Enterprise Linux 4 at work for any *nix tasks, and in this post…
Auto backup solution for your MySQL databases

Yoggie, a miniature security firewall appliance solution
