So you cannot use an array of 'scopes world-wide to create a virtual array.
If you had read the linked article then you would know that they are proposing to look for pulsed signals from a targeted star. Statistical analysis of data from thousands of scopes does improve performance on this task.
Years ago when I had some experience with shuttle operation there was always the issue of testing and certifying equipment as being safe. For example, that plastics don't outgass volitile compounds, things won't catch on fire, etc. Such certification can be expensive and involve a ton of paperwork. Say a $5 object requires $10,000 worth of assurance.
So unless you want to pay for this process, find equipment that has already been certified. Sorry but I can't help you here, but NASA probably can.
I would totally buy the arguement of not allowing patents on government funded research.
The bill is about prohibiting copyrights on reports of government funded research.
The patent issue was not mentioned.
I would be extreemly rare for any researcher to make much money by retaining the copyright to federally funded research. Maybe if somebody wrote a "thesis of the year" but most academic research books make little money for their authors.

PlanetLab also serves as a meta testbed on which multiple, more narrowly-defined virtual testbeds can be deployed. That is, if we generalize the notion of a service to include what might traditionally be thought of as a testbed, then multiple virtual testbeds can be deployed on PlanetLab.
Any time a discussion starts to use the word meta you know you have achieved buzzword satori and can stop reading.
Anything you can do I can do meta. I can do anything meta than you.
real power of Lisp being that everything, including the program itself is just a tree structure.
Lisp 1.5 in someways wasn't Lisp 2.0 because the original form of the language was in terms of "M-expressions" that looked like mathematical expressions and Fortran. The idea was to have a compiler that translated the M-expressions into the internall forms of S-expressions.
However as John McCarthy Says
The project of defining M-expressions precisely and compiling them or at least translating them into S-expressions was neither finalized nor explicitly abandoned. It just receded into the indefinite future, and a new generation of programmers appeared who preferred internal notation to any FORTRAN-like or ALGOL-like notation that could be devised.
It is much easier to be deeply familiar with just 1 representation of a program rather than to translate between several different forms..
Jukebox may be successful if it can entirely do away with the source format, and work entirely with tree representations.
Many people with cow milk allergies can drink goat milk because it contains a different kind of protein.
Goat milk has 13% less lactose than cow milk, and 41% less than human milk.
What triggered the writeup was the The American Society of Human Genetics journal article. For some reason the SFGate link also discussed the genetics of lactose intolerance, and here I will give some references and discuss how this is relevant to early human evolution and perhaps bottlenecks.
Genetic lactose intolerance (= hypolactasia = non-production of lactase enzymes past weaning) has a hereditary component (Sahi 1994)
It is assumed that thousands of years ago all people had hypolactasia in the same way as most mammals do today. At that time in cultures where milk consumption was started after childhood, lactase persistence had a selective advantage. Those people with lactase persistence were healthier and had more children than people with hypolactasia, and the frequency of the lactase persistence gene started to increase.
The Cambridge World History of Food (2000) has a good article on the science and geography of lactose intolerance. This problem is not caused by the gene that creates lactase but instead by another gene (LAC*R (lactase restriction)) that kicks in later and ramps down the primary gene. (The other allele LAC*P allows lactase production to persist) However that article says:
it seems most likely that the European and Arabia-Sahara centers of LAC*P prevalence, and the Uganda-Rwanda center (if it in fact exists), arose independently. Population movement and gene flow can be very extensive and, no doubt, have played a substantial role around the centers. Despite the efforts of some authors to find a common origin in the ancient Middle East, it is simpler to suggest independent origins than to postulate gene flow from the Middle East to Scandinavia and to the interior of East Africa. The problem might be resolved in the future if gene sequencing could show that the LAC*P alleles in Sweden and Saudi Arabia are, in fact, the same or are distinct forms of the gene with a similar function.
â¦
Finally, the LAC*P and LAC*R genes are interesting far beyond their biomedical significance. Along with linguistics, archaeology, and physical anthropology, further research on lactase genes and other genetic markers will provide clues to the prehistory of peoples, their migrations and interminglings, and the origins and development of major language families.
However in 2002 the LAC*P gene was identified and sequenced within a Finnish population and was found to be the same as those in the rest of the world. This means that genetic adaptation for adult milk drinking evolved early and all milk-drinkers have ancestors in some early population in the middle-east or Africa.
The problem with equating lactose intolerance with genetics is that people will see this as an either/or situation â" either you can eat it or you can't. The fact is that most intolerant people can consume small to medium amounts of lactose with no problem. Major milk problems are more often the result of allergies.
Eventually there is the issue of culture. Fermented milk products (e.g. yoghurt and cheese) may be easier to digest than raw milk. Do the cheese/yoghurt eaters have a cultural advantage? Or have they disadvantaged other cultures?
One obvious difference between the real machine and the fictional version is the fact that the movie Gammasphere emits gamma rays that cause Banner to transform from human to Hulk every now and then. The real Gammasphere detects the weak gamma ray signals emitted by decaying atoms, and is harmless
Don't these "real" scientists know anything about transducers? Anything a transducer can detect it can also emit. Thus microphones are speakers and vice versa. I am sure that there is someway that you can apply energy to a CCD photon detector and have it emit light. An if you can control the phase of the signals to the individual cells then the CCD array may emit frigging laser beams.
Note in the AIP write up they neglected to mention what sort of transducers they have which keeps the general public from knowing how easy they are to invert.
How much do you want to bet that most acceptible software in the DoD is there because of waivers? In the NSTISSP link it says:
(14) Waivers to this policy may be granted by the NSTISSC on a case-by-case basis. Requests for waivers, including a justification and explanatory details, shall be forwarded through the Director, National Security Agency (DIRNSA), ATTN: V1, who shall provide appropriate recommendations for NSTISSC consideration. Where time and circumstances may not allow for the full review and approval of the NSTISSC membership, the Chairman of the NSTISSC is authorized to approve waivers to this policy which may be necessary to support U.S. Government operations which are time-sensitive, or where U.S. lives may be at risk.
yeah, but they then go on to show that using a decent hash function doesn't cause such a big performance hit.
I think that crashing the Bro server was just meant to demonstrate that some and maybe a lot of code out there in the real world has vunerable hash functions.
If this device really works then the company should distribute downloadable emulations as an advertisement.
My PC came with a microphone, speakers, and headphones and it can run the trivial signal processing software. This is enough to test if the claims work.
Liking LISP, I find it annoying that most other languages do not make a distinction between changing variable values (assigning) and binding variables. Nor do the seem to notice that there is a large semantic difference.

Rosen's quitting was announced in January. Most of the comments being made now could and maybe were made then.
If they notify me via email that looks like spam I will probably just delete it. Same thing if it is paper mail that looks like junk mail.
Somebody, when they start the refunds please post info on what the refund looks like.

Here is the abstract from the The American Society of Human Genetics article, and here is Stanford's press release on the story.
And are the web pages of Marcus W. Feldman and Noah Rosenberg From Rosenberg's research page, here is access to a PDF of the journal article.
Note in the AIP write up they neglected to mention what sort of transducers they have which keeps the general public from knowing how easy they are to invert.
and here is a brief writeup from Nature.
I'd assume that the dragonfly merely tries to keep the thing it's hiding from in the same position on *its* retina.
But then wouldn't the prey disappear from the drogonfly's vision?
Boy, that MSNBC article was bad. They even mispelled the researcher's name. It is "Akiko Mizutani" not "Aikiko Mizutani".
Here is some better coverage of the story. discovery, NationalPost, and Ananova.
And here is a nice page from the Insect Vision, Navigation and "Cognition" Laboratory at ANU, but it doesn't cover the dragonfly work.
it's certainly not new

But nobody can beat this guy. (1.7M wmv file)
The winner was the guy with the most shit from an exploded foo on him, and got to walk away with the prize.
So, the moral is: "If the foo shits, wear it".

As someone who has been on the Water Rocket mailing list for years, this site was discussed several years ago. Still, it is fun and cute.
Science magazine decided to give free access to its reports on the sequenced genome of SARS. Rather enlightened of them.
