  1. How about this one? on Universal Alphanumeric Postal Code Proposed · · Score: 1

    There is a Hudson Street and Hudson Place and Hudson Street Extension all meeting in zipcode 14850.

  2. The Mississippi has been controlled on Three Gorges Dam Begins Storing Water · · Score: 1

    And its delta now loses dozes of square miles of land a year due to decreased silt. Controlling a river can have some undesirable effects.

  3. So basically on Searchking Loses Suit Against Google · · Score: 1

    If you're trying to get your PageRanked increase, you should just start suing people. Haha.

  4. Thanks to the Stanford-Berkeley rivalry on Searchking Loses Suit Against Google · · Score: 2, Interesting

    UC Berkeley is 16th place.

  5. On the plus side on Running a Research Lab on Free Software? · · Score: 1

    You don't have to worry about Windows crashing. Decoherance amazingly is usually a problem before Windows would crash by itself.

  6. Re:Do it on a project-by-project basis on Running a Research Lab on Free Software? · · Score: 1

    Maybe we can run Oog for President. Lets limit CEO pay instead of giving them huge income and dividend taxes.

    The thing that is really screwed up is that dividends and capital gains are taxed lower than wages. You know that stuff you get paid when you actually work for a living.

    Back in '98 companies wouldn't hire me as a programmer at $5.15 an hour. Now I'm a UC Berkeley Ph.D student. Yeah, I agree, to heck with corporations.

  7. I wrote some programs to do QC simulations on Running a Research Lab on Free Software? · · Score: 1

    I'm also doing Quantum Computing research, particularly, quantum error correction. I a program that simulated a the process of quantum error correction in terms of the Quantum state. That's rather inefficient, since you need a vector of 2^n elements to simulate an n qubit system. But after using that I was able to figure out when quantum error correcting codes are corrected, and then wrote a specific program to calculate those.

    Here's the paper I wrote:

    That's probably not true, but I've heard it so many times, that maybe it is true.

  9. Re:... near equivalents? on Fields Medals awarded · · Score: 1

    Well, since it's given only every 4 years, basically yes. This was also the first time in a while that they gave it to only two people. There had to be other people who had done really important work in the last 4 years.

  10. Re:Arrrgh on Fields Medals awarded · · Score: 1

    Quite often they go to higher dimensions, for instance John Milnor got the Field's Medal in 1962 for the structure of a 7 dimensional sphere.

  11. Re:a doughnut into a coffee cup on Fields Medals awarded · · Score: 1

    I'm not sure, I'm having trouble visualizing that. Anyways, though, a Sphere and a Sphere missing a point would be considered to be different. The latter would be equivilent to a point. Well, that's if you ignore the dimension, but a rigourous definition of dimension in topology is really hairy, anyways. Remember, we're not dealing with any sort of linear space, it might not even have a metric (distance between 2 points).

  12. Re:Arrrgh on Fields Medals awarded · · Score: 1

    Summed up shortly, it's a way of describing a space without necessarily having a metric (knowing the distance between 2 points). It's kind of counter-intuitive until you've studied it for a while, to say the least.

  13. Re:a doughnut into a coffee cup on Fields Medals awarded · · Score: 1

    If the coffee cup has a handle with a hole in it, then they're indentical. They both have a fundamental group isomorphic to Z, which basically means you can start at a point, run around the hole an integer number of times, and get back to where you started, and that line you draw can not be continiously deformed to a point, because of the hole in the middle.

  15. Re:This guy is really gifted on Fields Medals awarded · · Score: 1

    Most mathematicians do their best work when they're young anyways. People were surprised that Wiles proved Fermat's Last Theorem at the ripe old age of 40 or so.

    I guess that must have been before the NSA became the largest employer of pure mathematicians in the world.

  17. Re:... near equivalents? on Fields Medals awarded · · Score: 2, Funny

    There exists a homoorphism but not an isomorphism between the two. Maybe I shouldn't attempt math humor at 3am.

  18. Re:This is what it all comes to on Russian Agency Charges FBI Agent With Hacking · · Score: 2, Interesting

    Bush seems to think that Americans should be immune from other countries' laws. Of course, it's a rather American-centric point of view.

    60% of people recieving a phd in cs in this country are American citizens. And it's probably a fair amount higher in a lot of other fields. In fact only 0.6% of those applying for a H1B computer job have an American phd in cs.

    That's being generous. With just 200 million computers used for 100 million seconds, over a septillion pixels have been used. So that's only 0.00005 cents per pixel, not bad.

    Books can stay around for a long time. I have hundreds of books that are still readable even though they were published in the 1800s, some before the civil war. On the other hand most of my floppies from just 5-8 years ago are probably bad now.
