Linux Journal Live - Horror Stories
October 31st, 2008 by Shawn Powers in
The October 30th edition of Linux Journal Live focused on Horror Stories in the computer world. We discussed the ghostly ipchains, the dreaded rm -rf, and even the sinister dd dilemmas we've faced over the years. If you missed the live show, be sure to watch the recording... before it accidentally gets erased! (Just kidding, we learn from our mistakes, the video is totally backed up!)

There aren't many numbers that put the US national debt to shame, but here's one: 1,100,000,000,000,000. What's that? That's how many floating-point operations per second the Roadrunner supercomputer at Las Alamos can perform. That's about 100 FLOPS per dollar of US debt (unfortunately, the debt is winning the second derivative race). Read the article about Roadrunner in this month's High Performance Computing issue of LJ.
Along with that, find out how to program the Cell processor and how to use CUDA with your NVIDIA GPU. Also in this issue: Mr HandS (aka Kyle Rankin) gives us a few tips on using Compiz, Chef Marcel shows you how to get blogging off your plate quicker, Mick Bauer talks about Samba security, Dan Sawyer interviews Cory Doctrow and Doc talks about how information technology can affect democracy and fix the national debt (just kidding about that last part). That and more for your reading pleasure in this month's Linux Journal.
