Multiple APIs aren't cool

I spent time today porting some software from Linux to FreeBSD.

Someone thought it would be cool to use GUIDs. Of course, the FreeBSD implmentation is completely different from the Linux implmentation. Some people complain about Microsoft changing their API.

I would settle for the Open Source Operating systems having a more unified API. For example, why are there two different replacements for poll? (Linux: sys_epoll FreeBSD: kqueue)

Geez. Been a long time since I last posted. Maybe I should post more often.
