Finally Open Solaris is up!
You can download sources and compile them yourself! And it works! Several Pilot members, including me, have been doing that for some time. It's quite simple.
I've been involved with Open Solaris for several months now, as many other folks. It took a lot of time to open Solaris but they (we?) did it!
Solaris engineers prepared a little suprise on their blogs - so go to Sun's blog or better to Planet Sun which is a blog aggregator of Sun's blogs. I belive you would find there a lot of really interesting and technical staff about Solaris in a moment.
ps. I really love Source Browser - just try it!
