New blog post from me!

A year ago, I started reading about the history of California. I wrote a blog about it. A year later, here is a sequel.

If you've ever wondered what went on before the Gold Rush, I hope you find it interesting!

We've written a post mortem going over what we've learnt. You can read it here:

History is in the making
It's technology and ideas, not politics, that change our lives the most. History should reflect that.

Has anything good been written on how to document a codebase?

I don't mean tools for hosting docs etc. I mean advice for writing well so that a newcomer can learn how everything fits together at a high level and can then efficiently find whatever details they need to contribute.
