Zed loves Fossil SCM: http://www.fossil-scm.org/index.html/doc/tip/www/index.wiki

Fossil SCM is written by D. Richard Hipp. The same great guy behind SQLite.

This is a pattern I'm seeing from Zed:

1) loves small software (do one thing do it right)

2) loves C + glue code (perf in C, everything else script)

3) loves solid code

Some examples: SQLite3, Fossil SCM, Mongrel1/2, Merb (hinted by him), etc.

Wouldn't be surprised if he uses the tools developed by Dr. Hipps. Perhaps he prefers tools written by like-minded people.

What can I say, UNIX philosophy at its best?

Note: I like Dr. Hipp's software too (and OpenBSD). These tools are strong, solid, high quality, and represents everything that's good about software product. Unfortunately they're not the most "popular" thing out there.

Fossil SCM does not do one thing that does it right, it does many things actually, ticketing, wiki, scm and more I think.

I believe that all comes free with the scm he is using, fossil.

Oh. Right you are. I hadn't heard of it, but it looks interesting. Certainly a big time-saver to get all that for free.
