Understanding Microformats Let's take the mystery out of it: Microformats are nothing more (and nothing less) than using XHTML markup to more fully identify data. That's it. No magic, no mumbo jumbo.
I don't know Unix Most often "I don't know Unix" comes from a voice at the other end of the phone. I'm annoyed already, because it's pretty hard to find my phone number without learning that I don't want phone calls from non-customers who "have a simple question". Existing clients, sure, call me anytime. But there had better be a darn good reason for anyone else to ignore what they read at that contact info page.
Bash Brace Expansion The new tricks Bash has picked up in 3.0 are exciting and useful, but simple brace expansion has been available for some time now, and yet we seldom see it used. I suppose that's because the need doesn't come up too often.
