Ars Technica: Forum cracks the vintage passwords of Ken Thompson and other Unix pioneers. “As one of the original versions of Unix, BSD is an ancient operating system. So it shouldn’t come as a surprise that it used what are, by today’s standards, strange, even ridiculous security. For one, the hashing function protecting passwords, though state of the art 40 years ago, is now trivial to crack. Stranger still, the password hashes of some BSD creators were included in publicly available source code. And then, there are the passwords people chose.”
From Loige: Extracting data from Wikipedia using curl, grep, cut and other shell commands. “In this article I am going to show you how I was able to extract and process some information from Wikipedia only using a combination of common bash utilities like curl and grep.” What I really like about this article is that its author, Luciano Mammino, extends it in response to comments and external articles, and the comments themselves are well-worth reading. So well done Mr. Mammino.
