I can't agree with you about virtual machines easing the making of parallel programs. There is nothing they can do to make a multi-threaded program correct if the programmer is sloppy. When you talk in parallelization in applications, you are almost likely talking of threads and the inherent problem about them is the sharing of state (data) between two or more threads. This will require synchronization and it is not a straightforward reasoning to get. And it is solely on the shoulders of the programmer, not the runtime or the language.

+ - Raven: An Elegant Build for Java->

Submitted by kevin_conaway
kevin_conaway (585204) writes "Matthieu Riou wrote an interesting article on Raven, a build system for Java powered by Ruby. His premise is that Raven allows you access to the full power of a scripting language including things like conditions, loops, exceptions and complex data structures and that this is an improvement over linear, "toy" build systems like Ant and Maven."

Engadget: Wiimote repurposed for multi-point interactive whiteboard->

From feed by engfeed

Filed under: Misc. Gadgets

While certainly there's been no shortage of Wiimote hacks, the number of genuinely useful ones has been considerably more limited. It looks like you can now add one more to that list, however, as Johnny Chung Lee (he of the Wiimote finger-tracking hack) has now upped the usefulness even further with a makeshift multi-point interactive whiteboard. There's a bit more involved with this one than just a Wiimote, however -- namely, an IR-emitting pen (or two), which the Wiimote tracks while relaying all the necessary information back to a PC. That, as the video after the break shows, allows you to turn any surface into a multi-point whiteboard with the use of a projector, or turn any LCD screen into a touchscreen, of sorts. Best of all, Johnny has kindly provided the necessary software free of charge, so hit up the read link below if you want to give it a shot.
