We always find interesting things and some great learning materials. It's not fun to be happy alone, so I created this repository to share some interesting things that I have found myself.

WTF is the name of this repository? It’s always a headache to come up with a name, so I just use the random name generated by GitHub.

• Firewalling with OpenBSD's PF packet filter
• Daryl's TCP/IP Primer - I still remember the time I spent 3 months in my college library struggling with those stereotypical books just trying to understand the concept of a "layer". Three months, just to figure out a concept that could have been explained in 3 minutes. This made me realize how important it is to have an easy-to-understand reading materials.
• Teach Yourself Computer Science - This site might be familiar to many of you, but I want to share it anyway, because it was how I got started with computer science. We are always asked if we can use a tool, but we are rarely asked if we understand what's going on under the hood. It's unfortunate.
