Interviewing programmers: coding test results.
I've now stopped accepting new versions, so please don't send me any more. However, there has been such a strong reaction to this that I intend to offer another opportunity for people to write simple code and have it analysed and compared with others.

A micro-manual for Lisp implemented in C
Recently I had to go through some code that uses the uIP TCP/IP stack, which reminded me, it has been a long time since I did something in C so I ended up spending the weekend implementing the 10 rules John McCarthy described in his paper A Micro-Manual for Lisp - not the whole Truth .
