Streaming Multiple Live Channels?
Maxwell'sSilverLART asks: "I work for a University's Aviation Department. For several years now, we've run a streaming audio server to rebroadcast air traffic control communications over the web as an educational service to our students. This job had been handled by Winamp + SHOUTcast. We've just added a second channel to the system (we're now rebroadcasting approach control, in addition to the local tower), which means I need to find a way to get a second live audio stream into the system (signal comes from radio receivers tuned to the appropriate frequency), encoded (we're using 8-bit, 22kHz mono MP3, which is more than adequate given the source), and broadcast. Has anybody done this before? Surely I'm not the first to want to encode multiple live streams. How did you do it, and what were the pros/cons? Does anybody know of a good hardware device at a reasonable price (I'd need to sell my boss on two of them)? Ideas are always welcome.""I thought about setting up a Linux box with two sound cards, but I know that can be problematic, and I was also having trouble finding streaming software that would work with multiple soundcards (LiveIce only seems to support one). I would prefer not to use multiple machines. I was looking for software, and it occurred to me that I might be going about this the wrong way--perhaps a hardware encoder/server would be better. I poked around on the web, and only found one (for $2800--I'll pass). If I do end up using a PC, I want the system to be daemonized, and initialize at startup; I'm sick of having to restart Winamp every time the power cycles. (I inherited this system; I would have done things differently)"

P2P Internet Radio
fdsa writes "O'Reilly's openp2p.com has an article describing two programs for peer-to-peer audio streaming, Streamer and PeerCast. Streamer is currently Windows-only but GPLed, and desperately searching for somebody to port it to Linux. PeerCast was on slashdot before, but now runs on Linux and supports Ogg Vorbis. There's an impressive list of channels already. Planned features include video streaming and a "tip jar" system for paying artists. Setting up your own station is as simple as installing the oddcast winamp plugin or liveice for xmms." -
UK Publishes Asteroid Armageddon Report
szyzyg writes: "The UK NEO Task Force which was set up last year has finally delivered its report and recommendations on the Asteroid threat. The recommendations include money to build a 3 metre search telescope in the Southern Hemisphere, and more funding for research in the field. The report is written for politicians and makes a good introduction to the subject, including disturbing facts and figures." -
MP3.com Loses In Court
The Code Hog was among the first to write with the news that "CNBC is reporting that MP3.com lost its court case with RIAA; the court finding that MP3.com is infringing on 'thousands' of artists property." Alert readers like Szyzyg and SethJohnson contributed links to coverage on zdnet and on yahoo respectively. -
Betelgeuse Breathing
szyzyg writes "For the fisrt time ever astronomers have been able to observe waves and flows on the surface of a star other than the sun. Alex Lobel and Andrea Dupree managed to detect these flows on the surface of the supergiant Betelgeuse - the bright red star in the constellation of Orion. This star is so large that its radius is about the same as the distance at which the earth orbits.... i.e. about 150 million km. It's almost at the upper limit for stellar sizes predicted by Eddington " -
UK Govt Plans To Set Up 'Armageddon' Centre
Scott Manley writes "According to the Sunday Times, and the BBC the UK government is putting together a task force to advise the government on Extraterrestrial hazards. Professor Mark Bailey has been campaigning for this for a long time - and it seems timely for such a thing after his staff at Armagh Observatory made the first accurate prediction of a meteor shower.

Killer Asteroid
Scott Manley writes "Astronomers have found a mile wide asteroid which has a non-zero possibility of hitting the earth i n the next century. Asteroid 1999 AN10 was found on 13th January '99 by the LINEAR system and scientists working in Italy have predicted a close approach in August 2027 and a potential collision in August 2039. This has been kept quiet after the panic last year over 1997 XF11 whic had a similar 'remote' possibility, if 1999 AN10 were to hit it would be a real civilisation killer. " I can't believe scientists are bothing with this stuff when we all know Y2k will kill us all in less than a year anyway.
