To make the dust layer reflection more reliable, there was in the
1960's a military program to put needles (well, dipoles) in low Earth orbit to form an artificial reflecting layer. I forget the name, but it
was run by MIT Lincoln Labs. After a huge controversy (about polluting outer space!),
it flew and... nothing happened. Not
enough needles, I guess.
Of course, this was at a time when they were
(in Project Starfish) exploding nukes 600 km up to
see what it would do to the ionosphere...
Cisco offers their
IPTV, which is commercially
available.
There are several H.323 streaming server commercially available as well. This standard is
used by many
Internet2 video applications.
There are also open source alternatives.
The vic vac and rat tools long in use on the old mbone are certainly
available in open source :
for
netbsd and
for
Linux.(You might want to
read
this
before
you get into these.)
If you want to multicast your streaming video,
you should contact
Multicast Tech.
My understanding, from talking to people who buy bandwidth for a living, is that Cogent is way, way, underprovisioned for transit for their bandwidth, but that their backbone provisioning is OK. What this means is that, if you are doing data transfers within Cogent's network, you're OK, but if you expect to download at the promised speed from another network (highly likely with, say, web trafic), you'll be disappointed.
The so called War on Drugs is not about people's health, it is (like all wars) the continuation of politics by other means. The "War on Swapping" will only come into being if one side in a political struggle sees it as useful in repressing the views, opinions, political activity etc. of the other side. This might happen, but it won't come from RIAA.
If you go to the technical paper you will see that they claim a factor of 4 (or 12 dB). Somehow someone has confused 12 dB with a factor of 12 compression, which they do NOT claim.
Anyway, this is a static compression factor. The big problem in video compression is taking into account frame to frame changes. This is why a (broadcast quality) MPEG 4 video takes 1 MBit per second to show talking heads, but 3 Mbit per second plus to show, e.g., a basketball game. How well their static technique helps video codecs will depend on how easy it is to adapt it to the dynamic problem.
I think that the Record Companies may be winning the battles but loosing the war. They can shut down a company, but can they stop a Movement ? They are scared, no doubt about it - don't believe their hype. See Scott Rosenberg in Salon and the discussion on Buzzwaves for a longer view.
The thing about Mars is that the entire surface is at too low a surface pressure for liquid water to last long (it's below the triple point). This pretty much rules out pools, unless the chemistry is really strange, but not hot springs. That woould definitely be worth a trip !
IMHO, the real problem here is the monoculture that MS infatuated IT departments encourage. These viruses / worms do not affect Macintosh, Linux and Unix users, because they are not part of the monoculture. How many times do you see the so-called "experts" say "One way to cut down on these attacks is simply not to use so much software from Microsoft." ? NEVER. Maybe some of the Linux UGs should prepare and send out press releases after the next attack pointing this out.
1.) The Soviets had a series of reactor powered radar missions designed to look for ships. Most of those are still up there in high orbits - one dropped radioactive material on Canada in the late 1970's. Apollo 13 also had a RTG that I believe is in the Pacific ocean now. 2.) Note that every surface or air test of a Plutonium bomb released kilgrams of the stuff into the air! Over the life of the cold war there were literally metric tons of Plutonium released into our atmosphere by such tests. We're still here. If Cassini had hit the atmosphere over your house, you'ld be still here too. BTW, I am just a space junkie, not a classified person, but I was aware of all of the missions in http://www.deepcold.com/ except for the Zvezda mission, which is just a modified Soyuz
As it says here : http://www.wired.com/news/business/0,1367,35848,00 .html this is not costing them money, it's making them money. When web music is paying $100 million to $ 1 billion plus per year into the hands of the performers, these arguments will seem quaint.
Hello; Enrico Fermi once said that real scientific advances took time to be adopted because the old generation had to die out first. If this Librarian doesn't digitize the books, the next one will, or the one after that
Happy Holidays to all; The DMCA was, IMHO, designed to protect the Secure Digital Music Initiative (SDMI) of the RIAA. Basically, it makes it illegal to crack music encoded using the SDMI or other types of protection, such as digital watermarks. The SDMI, promised for Christmas '98, remains vapourware, but the law is there. The prohibition on cracking protected music starts October 28, 2000. However, starting Oct 28, 1998, the distribution of CODE that violates a "technological protection measure" is outlawed. (Yes, that's right - regardless of the merits of this case,/. people can USE these products legally at the present!) Futher, the DCMA only prohibits the cracking of access measures, not copy protection. The interoperability loophole is fairly narrow, and probably won't help Streambox much. However, the law seems clear (although I am not a lawyer) : The DMCA prohibits the sale of code that is PRIMARILY intended to circumvent protection against unauthorized access (or that is marketed as such). It does NOT prohibit measures to circumvent copy protection per se. It seems to me that Real has a tough road to hoe : 1.) They would have to show that their format is used to prevent unauthorized access AND 2.) They would have to show that Streambox is PRIMARILY intended to get around that prevention, or is marketed as such. Now, I am a MP3 man myself, but I am not aware of any such access limits in the REAL format. Can't anyone get software that plays this ? Can't you download the Real software itself for free ? And use it for free ? Then how can Real show # 1 ? Even if Real could show that you cannot copy the Real format (is this really true???), that doesn't seem to be enough - it's access protection that is limited. Even so, if Real proves # 1, given the wide range of uses of Streambox, and its similarity to other products, how can they show # 2 ? I just don't see how the Real suit has much merit, unless Streambox was VERY stupid in what they said in their advertising.

After seeing (and being very disappointed by) Star Wars : Phantom Menace, I would like for this to be good, but don't have a lot of hope...
Also, a mirror site would be nice. tolkienonline.com has melted down.
