Sun has announced the launch of OpenSolaris. This is their answer to Linux, and will be released under a 'CDDL' license that is much friendlier than the GPL. They still plan to brand and sell the proprietary version of Solaris (building on the open source developement). They don't have the code up on the site yet, (just a single module), but it is planned for the end of this month. Additionally they have opened some 1,670 patents to open-source developers. Iím getting a feeling of deja vu here. Feels like netscape all over again. You can read more about this here.
