Microsoft released version 4.0 of its .Net Micro framework under the Apache 2.0 licence. That's right, the .Net Micro development framework is now open source. The TCP/IP stack and cryptography stack are still closed, however, because a third-party owns the software. The .Net Micro framework is a development and execution environment for small devices.

A U.S. District Court judge ruled that Psystar's Mac clones infringe on Apple's copyrights. Psystar made the case that it could run the Mac OS X on non-Apple machines. Apparently, Psystar didn't read the Mac OS X end user license agreement, which states that the Mac OS may only be installed on Apple computers.

If Oracle were to sell MySQL to a third-party, who would it be? Many thought Red Hat was the obvious choice with thier JBoss open source division. Reporters have been asking Florian Mueller for his prediction for quite a while now and he finally answered: Novell. However, Novell was introduced to open source by a loan from IBM, and it seems Oracle is unlikely to spin off MySQL to a friend...

Can't stand your tiny 30-inch, panoramic monitor? Why not upgrade with the single-slot Matrox M9188 PCIe x16 graphics card? It drives eight monitors, each at 2560 x 1600 pixels. If eight monitors isn't enough, try combining two for a seamless, 16 monitor desktop.

Groovy, Sometimes You Still Need a Semicolon.

scottleber — Fri, 06 Nov 2009 10:22:27 +0000

Like Javascript, semicolons are optional in Groovy except for when they aren't optional.
