Oracle has released an early version of Java 7. It promises some important features, most importantly native support for other languages on JVM. Speaking of which, O'Reilly has a short summary. Also from Oracle, new version of VirtualBox is mostly a bugfix release.
Samsung, as a part of Khronos group, is working to make GPUs useful (yep, I'm not a gamer, for me they're useless power drains most of the time). You've probably heard of OpenCL, a platform for running all-purpose software on GPUs or special-purpose accelerators (with a nice feature of falling back to CPU if nothing else is available). WebCL is a JavaScript binding for OpenCL that allows to use GPU computing in client-side web apps. Samsung not only released the WebCL implementation, it also did it under BSD license, meaning it's free to use for any purpose.
On more personal side, I got a couple of machines for an experimental XenServer pool, meaning I can test new features without jeopardizing production VMs. Shiny!
