Old blog posts, restored

Digging through some backups, I found some additional old blog posts worth restoring.

From October 2004, a measure for effort of thought, the milliEinstein.

I once asked What’s wrong with newsgroups?; the passage of time has provided some of the answers.

Specification by example is a useful testing technique that is perhaps underused.

Back in March 2006, I was impressed when the Martian rovers clocked up nearly 800 sols of activity on Mars. Little were we to know just how hardy those rovers were to be. Spirit continued working for 2623 sols, while Opportunity clocked up 5111 sols before failing. Not bad for two robots with a 90 sol design lifetime!
