On the Quest for Blazing Performance – NginX, DNS, and caching (Part 1)

Not because I am the biggest expert in the world, but because I have been wrongheaded about the issue in the past.

One Keyboard to rule them all (Reviews)
Since I’ve become what can only be d3scr1b3d as an ultrahacker (I can break encryption keys in 12 languages, I go by the hacker alias N3O, and apparently help my landlady take out the trash. One of these lives has a future… the other does not.), I’ve decided to upgrade my computing center to the mega-ultra-command complex of usability that it deserves.... Read more →
