Web Upd8: Ubuntu / Linux blog
OMG! Ubuntu! | Everything Ubuntu. Daily.
Three years ago, Joseph Sneddon and I were put in touch through mutual friends at a Psychology conference in Australia. We both have extensive backgrounds in Computer Science and Psychology, and were intrigued at the emergence of online communities over the past decade. Shortly thereafter, we embarked on an international post-graduate collaborative experiment that set out to investigate tribal behaviour in online communities. A collaboration was formed between our two Universities, The University of Otago in Dunedin, New Zealand, and the University of Lincoln in the United Kingdom. We spent several weeks attempting to figure out how to collect information in a way that wouldn’t hamper the results, and eventually we started OMG! Ubuntu!
Malicious Linux Commands -
From (This article was originally published in Ubuntu Forums but has recently been removed there. Ubuntuguide feels that knowledge about these risks is more important than any misguided attempts to "protect the public" by hiding their potential dangers or protect the (K)Ubuntu/Linux image.

More Linux Commands - A practical reference
My previous reference for practical Linux commands was surprisingly popular with over 3.5 million hits in nearly 5 years. So I've decided to start compiling another list of somewhat more involved/esoteric commands.commandlinefu.com is the place to record those command-line gems that you return to again and again. Delete that bloated snippets file you've been using and share your personal repository with the world. That way others can gain from your CLI wisdom and you from theirs too. All commands can be commented on, discussed and voted up or down.

Linux Newbie Guide by Stan, Peter and Marie Klimas
Intro. We are relative Linux newbies (with Linux since Summer 1998). We run mostly RedHat and Mandrake -> the solutions might not be directly applicable to other Linux distributions (although most of them probably will be). Hope this helps; we try to be as practical as possible.
