I WANT TO STAY UP ALL NIGHT PLAYING WITH MY NEW TOY BUT I ALREADY STAYED UP HALF THE NIGHT LISTENING TO STREET CHANT ):
I've been waiting a very long time for this:

BeOS and Haiku, its open-sourced phoenix were the operating systems that got me excited about operating systems. This was back before I knew how to subscribe to a blog or anything. Back when I thought blogs were just online diaries.
Anway, you can download the alpha 2 here. They're offering .iso, .vmx/.vmdk and Anyboot files. I'm running it in Virtualbox right now. No internet because it only supports WEP encryption and obvs we're on WPA2 here. Maybe tomorrow I'll get all ethernetted up in between boughts of fighting with the USB interface I'm recording with and writing smooth as, stone cold jams.
(Side note: Crashes for no reason but I can't tell if it's a Virtualbox thing or a Haiku thing. I'm going to go with Virtualbox because I'm an asshole.)
Go on, whine about it.
