The other bit is that, having just released an Absolute OpenBSD update, his Absolute FreeBSD book will not see an update… until the FreeBSD installer gets more coherent.

OpenBSD packages: an overview
Peter N. M. Hansteen has a long writeup about using and creating ports on OpenBSD, which is apparently a reprint of an article he wrote for BSD Magazine back in 2008.

Lazy Reading for 2013/04/07
It’s a week past Easter and I’m actually tired of eating chocolate. I never thought I’d say that.
On fat men and jellybeans, about how the press is reporting DDOS attacks. Related: Reporting on tech stories is very difficult; there’s very little photogenic material. I’d love to have more pictures on the Diges [...]
