  1. Are circular orbits really less common? on Planetary System Similar to Sol Discovered · · Score: 2, Insightful
    Circular orbits are less common than highly elliptical orbits, and are more promising.

    Is that true? If so, how do we know?

    Remember that the only way we can currently detect planets outside our own solar system is by their gravitational influence on the primary star, and the effect is right on the edge of what we can detect. We're seeing lots of massive gas giants in orbits that bring them close to their primaries because we can't (yet) detect anything else.

    In our own solar system, the gas giants are in large circular orbits. If our solar system is typical, we're only seeing a small distorted sample of what's out there.

  2. Re:The result of my attempted post... on Planetary System Similar to Sol Discovered · · Score: 2, Interesting

    In case you didn't notice, 277205 hours ago (well, now about 277206 hours) was January 1, 1970, aka the Unix epoch. Some timestamp was incorrectly set to 0 (or perhaps -1).

  3. Not just NCSA on NCSA To Build $53 Million, 13-Teraflop Facility · · Score: 1
    The title on this article is a bit misleading. As the press release says, NCSA is just one of the four institutions involved in this project. The others are SDSC, Argonne National Laboratory, and Caltech's CACR (Center for Advanced Computing Research).

    NCSA is certainly an important part of this partnership, but they're neither the only part nor the lead site.

  4. Re:Too lazy no right to vote on Caltech & MIT Urge Wait On Net Voting · · Score: 1
    Having "enough friction against voting" to weed out those who don't care is fine in theory, but in practice there are some serious problems with the idea. If there happens to be more "friction" in poor areas, or areas that tend to vote for one particular party, it can and will change the outcome of the election.

    Disenfranchising stupid and lazy people would be ok, but (just to pick a random example) disenfranchising stupid and lazy Democrats without disenfranchising stupid and lazy Republicans is a very effective way to steal an election -- deliberately or not.

  5. This isn't really new on Virtual Tour Of The Orion Nebula · · Score: 2

    This animation was actually done in 1999 or so. There's a lot more information at http://vis.sdsc.edu/research/orion.html. (The Washington Post article doesn't credit the San Diego Supercomputer Center.)

  6. C/C++?!?! on Java as a CS Introductory Language? · · Score: 1

    What is this "C/C++" everyone keeps talking about? C and C++ are two different languages. They're similar in many ways, but treating them as one language leads to bad C and bad C++.

  7. Re:this one is nice... on What Formula Would You Tattoo? · · Score: 1

    I have my own version of this one ("+/-" is supposed to be a plus-or-minus symbol):

    e^(i*pi) = 0 +/- 5%

    Of course, you'll want it in mathematical notation rather than ASCIIfied.

  8. Re:Actuallty, Microsoft has broken the GPL on I Suspect M$ That Has Broken The GPL · · Score: 1
    Take a look at Microsoft's own web page at http://www.microsoft.com/unix/interop/default.asp:

  10. Re:Wait a second.... on New 'Planet' Discovered in Solar System · · Score: 1

    The odds against that are ... well, astronomical.
