Five Ubuntu Features You Didn’t Know About
Feb 15th
The quest to discover something new and fresh about Ubuntu, which is arguably the world’s most popular and best documented Linux distribution, is an almost ridiculous one to accept and an almost impossible one to fulfill. I felt like the Mission Impossible character, Jim Phelps, as I read the request from my editor. I expected to see the words, “This is your mission, Ken, should you choose to accept it. This email will self-destruct in five seconds” at the end of that message.
Rinetd: Redirect TCP connections from one IP address and port to another
Jan 19th

PDF files and passwords using Commandline
