Comment: Volume is not the same as loudness (Score 1) 289 289

It all depends on how the bill is written. Volume is not the same as loudness. If you take the commercial/whatever and use audio compression and processing gear (or software) you can crunch the crap out of the commercial, do a little frequency shaping, etc. and it will -sound- a lot louder than less processed audio. Yet, you can show using VU meters, peak meters, and similar 'volume measuring' devices and they will show the program and commercial audio as being about the same. The levels (amplitude) peak and otherwise will not exceed a particular value yet the heavily processed commercial can still sound like it's blasting you. It's all in the processing/shaping/limiting etc. And, of course, how the bill specifies that the 'volume' be measured or determined.

Stanford's Free Computer Science Courses 161 161

mikejuk writes "Stanford University is offering the online world more of its undergraduate level CS courses. These free courses consist of You Tube videos with computer-marked quizzes and programming assignments. The ball had been started rolling by Sebastian Thrun and Peter Norvig's free online version of their Stanford AI class, for which they hoped to reach an audience in the order of a hundred thousand, a target which they seem to have achieved. As well as the previously announced Machine learning course you can now sign up to any of: Computer Science 101, Software as a Service, Human-Computer Interaction, Natural Language Processing, Game Theory, Probabilistic Graphical Models, Cryptography and Design and Analysis of Algorithms. Almost a complete computer science course and they are adding more. Introductory videos and details are available from each courses website."

Ask Slashdot: Best Use For a New Supercomputing Cluster? 387 387

Supp0rtLinux writes "In about 2 weeks time I will be receiving everything necessary to build the largest x86_64-based supercomputer on the east coast of the U.S. (at least until someone takes the title away from us). It's spec'ed to start with 1200 dual-socket six-core servers. We primarily do life-science/health/biology related tasks on our existing (fairly small) HPC. We intend to continue this usage, but to also open it up for new uses (energy comes to mind). Additionally, we'd like to lease access to recoup some of our costs. So, what's the best Linux distro for something of this size and scale? Any that include a chargeback option/module? Additionally, due to cost contracts, we have to choose either InfiniBand or 10Gb Ethernet for the backend: which would Slashdot readers go with if they had to choose? Either way, all nodes will have four 1Gbps Ethernet ports. Finally, all nodes include only a basic onboard GPU. We intend to put powerful GPUs into the PCI-e slot and open up the new HPC for GPU related crunching. Any suggestions on the most powerful Linux friendly PCI-e GPU available?"

Wake me when streaming video looks as good as Blu-Ray (or even DVD), has 5.1 DTS sound, lets me select chapters, has special features, etc. I didn't buy an expensive 62" high-def display, Oppo BD player, component surround sound system, and nice speakers so I can watch the crap quality of what Netflix and everyone else today calls HD. Even with 15 mbps cable internet it still looks and sounds like crap compared to BD and DVD. I've been a faithful Netflix customer for quite a long time and gladly pay the extra fee for BD and the new rates. But, it's becoming obvious that Netflix and all the other providers want to completely eliminate disks and go solely with streaming to cut costs and increase profit. I'm an old guy so let me just say - BAH!

Geek Nostalgia? At work I still have to maintain two old SCO Xenix boxes. They are for a Wegener ANCS satellite control system. Since Xenix knows nothing about networking I move files in and out of the systems via serial port using Kermit. If a hard drive crashes and I need to reinstall Xenix it's done with a batch of 3.5" floppy disks. Fortunately SCO did issue a Y2K patch. I guess that's enough nostalgia for me. If I need more there's always the DOS 6 box that runs a monitoring system. Yes, I'm an old guy.

I am a senior citizen and I'm all for going somewhere else to escape the world all of you youngsters are going to inherit. However, I'd really prefer Mars to the moon. The moon is just too freakin' close to earth and likely to be destroyed or seriously pummeled with debris when you youngsters finally blow it up.

There are never any bugs you haven't found yet.
