Submission + - Google's Secret Switch to the Next Wave of Networking (

infomodity writes: What started as a Stanford project (Stanford Clean Slate) to design an Internet with decades of hindsight as a guide is now being put into practice by Google using OpenFlow. SDN, or Software Defined Networking, is a way of decoupling data and control planes, allowing an open software community to thrive in what is historically a proprietary, ASIC based networking space. With routing and switching control planes becoming open, what will the networks of tomorrow look like?

Submission + - 30 Years of the TRS-80 Model 100 (

An anonymous reader writes: An interview with John R Hogerhuis, one of the key players in the still suprisingly active community for the TRS-80 Model 100 portable computer.

As the Model 100 approaches its 30th birthday, John talks about what has kept the machine popular for so long, current software and hardware work that is keeping it relevant, and what modern developers could learn from spending some on a computer from 1983.

Comment Went to Notacon 9 / PixelJam, had a great time (Score 5, Informative) 58

I want to thank Froggy for running Notacon for 9 years. I used to help out with Phreaknic in Nashville and I know a little bit of what it takes to run a con. It's thankless work. This year was my third Notacon, always have a good time. It's a great mix of technology, hacking, and art.

The accompanying PixelJam ran flawlessly and had a lot of great entries in the competitions. Friday night there were great performances. Highlight of Friday was Morgan Higby-Flowers' performance on a circuit bent video mixer. All the audio and video was coming out of one box. He coaxed more sub-bass, fractured noise and glitch visuals out of one piece of antiquated hardware than I've seen other artists get out of racks of expensive modular equipment costing tens of thousands of dollars. More is less.

Good starting points for learning more about Glitch:

Nick Briz's site. He's been at this a while and co-founded the GLI.TC/H festival in Chicago.

Nick's Glitch Codec Tutorial. Also available as a DVD ISO.

Evan Meaney teaches at the University of Tennessee, is a founding member of GLI.TC/H, and also works on projects at Oak Ridge National Laboratories supercomputers.

For all the haters on the thread, I totally understand how this might not be your thing. That's what's great about great art: it is polarizing. Your hate makes me know I'm enjoying something special.

Comment Network security in a "virtual datacenter OS" (Score 4, Interesting) 121

We have IEEE and RFC for standardization of ethernet/switching and routing respectively. What standards exist for virtual environments? As commercial security vendors move into this space, we're headed back into a cycle of supporting multiple architectures. "Security Vendor X" must now understand how VMWare, Hyper-V, Xen, and other VM environments perform their networking. Virtualization of the entire OSI model renders the physical and data link layers obsolete. Why emulate them at that point? Not to say ethernet will disappear, but I can see a point where operating systems evolve branches that run in pure play virtual environments. Those offshoots will shed unnecessary things like MAC addresses as the VM vendors begin defining the new network standards themselves.
