Did I mention that I love Stack Overflow? It's a Q&A site for anything that is related to computer programing, and the creators (luckily) didn't just stop there. They went on to create a bunch of other sites using the same technology and branding, covering other topics (and they aggregate the best new content from those sites).
Enough with background info. What prompted this post is the answer to the question, "what's the difference between apt-get and aptitude?". This is from one of their sites, Unix and Linux, and the answer is really thorough. Part of the question was "what the heck is wajig" and I really liked how that part was handled as well. It serves as a nice reminder of why the heck I'm working on wajig in the first place... it rocks!
