Micropolis ported to FreeBSD

Today I have ported (a rather hacky patch) Micropolis (a GPL’ed version of SimCity) to FreeBSD.

(20080114) Note: the patch is based on the git version of micropolis-activity, as available from git://dev.laptop.org/projects/micropolis-activity .

BSD ar(1) announced

Kai Wang has announced today the BSD ar(1) is available for wider testing. This is amazing work, the creation and list speed are 5-20 times faster than GNU ar(1), and extraction speed is also slightly better than GNU ar(1).

It is also important to note that this version is completely BSD-licensed (yes, that means that you are free from the lair’s license), and is a piece of the vital parts of the FreeBSD DTrace work.
