  1. The real reason you can't shout "fire"... on The Village Voice On The DVD Wars · · Score: 2

    You can't falsely shout "Fire" in a crowded theatre.

    Actually, the reason you can't shout "Fire" in a crowded theatre has nothing to do we free speech and everything to do with contract law. When you buy a ticket you are essentially entering into a contract of sorts with the movie theatre - in exchange for your money you are allowed to watch the movie. If you shout "fire" and everyone leaves, essentially you have caused a breach of that contract by infringing on everyone else's viewing of the movie and the theatre's showing of the movie.

    As for live stage theatre, the same principle applies.

    I know it's hard to realize they're not significantly different. If you read only the mainstream press, listen to mainstream radio talk shows, and watch mainstream TV, you'll hear the minute differences between them emphasized again and again and again, until you start to believe those differences are huge.

    When I was growing up my parents would tell me about countries less off than the United States in terms of governments. One thing I remember was how in countries such as the U.S.S.R. (as it was at the time) how voting consisted of one candidate which you basically had to vote for.

    Now we are in a similar situation - there was even a sketch on Saturday Night Live about how alike Bush and Gore are. So what's the difference between having two nearly identical candidates to vote for and one? How many people are going to vote independant when no independant candidate has gained an electoral vote since early in this (20th) century?

  5. A review of the Expedition model on Solar Cells For Laptops? · · Score: 2

    I've got an expedition model of this series that I purchased a few months ago. A bit pricey (around $400+ i think) and I haven't quite got it to go quite to the full rated spec of around 20 Watts, but the cell is supposed to be more efficient at higher ambient temperatures.

    With passive resistive loads I've seen as high as 16-17W (but on cold days as low as 10-13W!), but keep in mind if you run it through an inverter you are going to get some loss probably 2-3W. To bypass this problem I bought a 50 Watt zener diode at the rated voltage of the DC input (around 16V for my laptop). (Cost around $12 versus $75-$100 for an invertor). In my research I came across this site from which I learned that solar cells act like current sources, which is ideal for a zener diode. The diode essentially syphons off all the extra current your laptop uses, and since it is placed in parallel with your laptop it doesn't draw any power that your laptop can use. The zener also regulates the voltage fairly well. The 50W rating is necessary because there is no series limiting resistor and thus the zener should be able to sink twice the rated capacity of the solar panel (to be on the safe side, especially if you don't have a heat sink ;)

    I also played around with the idea of some kind of mirrors to focus more sunlight on the panel, but then I figured that kind cuts down on the portability of the system. The panel itself is fairly lightweight, around 3 pounds I think, same as my laptop :-)

  8. The Physics of God on The Mind of God · · Score: 1

    My take on this whole subject is that the concept of "God" is backward. Trying to prove the existence or non-existence of God supposes that the definition of God is axomatic. Every religion I have seen defines God somewhat differently (is God infinite? an individual? engendered? offspringless?) the topic because more of a contest to see who can provide the most "authoritative" ancient documents to support their claim.

    From what I have seen, many scientists view God in a way similar to Einstein - not so much as a person as the laws of the universe. There is some evidence that many ancient esoteric sects held this point of view.

    But such a view seems somewhat ridiculous to me. How can the non-computable origins of the universe be worthy of anything a god could be? Worship, admiration, or whatever traits psychologists would says the human psyche desires in a god. Ancient gods were largely portrayed as people, or individual beings at the least, not omnipotent or omnipresent but having skills that exceeded any human. As such, the contemporary attempt at merging science with God probably won't be any more real than trying to explain psychology using math.

  9. Hey it has happened on Grok Goldbach, Grab Gold · · Score: 1

    There was actually a case where something along those lines happened. A man stood up, wrote on the chalkboard for about 15 minutes, turned around and got a standing ovation.

    If I remember right, he found the factors to a really large number thought to be prime. When they asked him how he did it they expected some complicated answer. Instead, it turned out he had spent the last 20 years or so multiplying out prime numbers - by hand - in his spare time. No real technical math background.

    Granted, much easier than this problem. Interestingly enough, plotting the number of matches for each even number seems to increase almost linearly. Proving no dips to zero on the hand is harder =)

  10. So how would one go about claiming this prize? on Grok Goldbach, Grab Gold · · Score: 2

    Faber has stipulated that the proof must be submitted to a respectable mathematical journal within two years of the book's publication next week, and published within four years. A panel of world-renowned mathematicians will be appointed to decide whether the proof is valid (Faber is refusing to disclose the panel's names, for fear that they will be flooded with letters from amateurs).

    I have a serious question here, and I hope that someone might be able to answer it.

    From the tone of the article, it sounds like they are expecting somebody in the mathematical community to submit it, if anybody does. How would say, me, your average slashdot reader, go about claiming such a prize? I have no idea how one would go about publishing something in a mathematical journal, and with such a prize at stake how would one prevent one's proof from being stolen by someone else (like a person you find to "help" you get it published)?

  11. Re:Mathematica - ugh on Open Source Symbolic Math Program? · · Score: 3

    I purchased Mathematica 3.0 when I was a student and I agree, the password problem was REALLY annoying. I recently upgraded to version 4.0 with the student upgrade discount (around $350 versus $79 for the student version or over $1000 for the non-discounted version) and I must say it was certainly worth it. I was expecting the password mess so I installed it on a laptop, so I could easily take it wherever I went without having to get new passwords. Guess what! It didn't even ask for a password! I suspect the student version uses a password because Wolfram is afraid of students pirating the software.

    All in all I consider Mathematica to be one of those rare pieces of software that actually have enough merit to be worth every penny paid for them. All of the few bugs I found in version 3.0 have been fixed in 4.0 (for example, I can now find the 1 trillionth prime number without a problem). And the fact that Mathematica does run under Linux is nice too.

    In the past I have thought it might be useful to someday start a project to develop a free version of Mathematica. IMHO Mathematica is the best technical computing package available, bar none, and a version with source available would be even sweeter. However, consider this -- a good deal of the functionality in Mathematica is actually written in the Mathematica language. There is a lot of Mathematica source available that comes with the package. Most of the low-level underlying stuff you don't really need the source code for anyway.

    As for the comment about arcane language, Mathematica's language is about the cleanest that i've seen. It uses a simple underlying list form (Head, Element,... where Head is a function, data type, etc.) and builds on that to support virtually every known mathematical function, notation, programming style, etc. Lest I seem to exuberant keep in mind it's really optimized towards symbolic and numerical computations, so it really doesn't work as well with things that traditional command line tools such as perl can do much better.

  12. on human proxies, AI, and philandering with horses on Utah About to Sign Library Filtering Law · · Score: 2

    But after our report came out, they unblocked it - so now patrons could read about how to have sex with a horse

    I assume that you mean "how to have sex with a horse without getting hurt or killed"???

    none of it can get around the fundamental problem: computer algorithms aren't up to the task of categorizing human expression

    There are two ways around this that I can see. The first is to use human proxies. On a local TV station we get I keep seeing advertisements for an Internet service that supposedly has people "monitoring web 24 hours a day". I can't imagine they are actually using people to proxy the data before returning it, simply due to the sheer volume of web requests. But such a thing could be possible - if each request page first displayed on a human operator's terminal, the operator could reject pages which violated the ISP's TOS. (that is, people could sign up, essentially agreeing that they subscribed to the ISP's standards and wanted things outside that standard filtered out. While I'm definitely not in favor of censorship the above type of agreement wouldn't be violating the reader's rights any more than a news filtering service would.)

    The big problem with human proxies is of course the sheer volume of requests. What are you going to do, have 10,000 workers filtering requests (expensive to say the least), or are you going to impose a 1 minute delay on every page your request? This method might work in a small town where one person might (a big maybe here too) be able to monitor pages for a few computers. But a better use of this technology might be in conjunction with existing filtering technology - if a page comes up blocked, forward it to a human proxy who can decide if the page was blocked in error. Of course this doesn't block potentially offensive material that misses the filter, and costs a lot of money.

    In the long term, those who insist on filtering Internet content need to get much smarter software, software that doesn't exist today. "Bad" words or offensive language in the page? Replace them with a non-offensive word or simply "bleep" them out. That way you don't throw out pages simply because the contain expletives. As for pornography, how about an AI program that get's trained as to what pornographic pictures look like, which can then assign a probability that an unknown pictures is pornographic. Pictures above a certain threshold would be blocked.

    All the above solutions of course would take a lot of work and a lot of money. They aren't easy solutions, and unfortunately there isn't much more political value in them than "knee-jerk" censorship.

  13. open source money on Gnucash 1.3.0 Beta Released · · Score: 4

    Managing your finances from your PC is good. Managing your financies with free software is better. Why? If you are like me, do you really trust a closed source program with all your important, confidential information? Sure, maybe a credit card number here and there to buy stuff over the web, but there is a level of protection there. If somebody steals your number your liability is limited. But if somebody manages to get ahold of your private finances, it's less like somebody stole your wallet and more like somebody broke into your house and looked at all your private letters.

    It seems to me that there are two benefits to an open source financial program. First, you can be as sure of your security as you are willing to study the source code. This means that you are better protected both against attackers AND against the off chance of backdoors or other security problems that might (but probably wouldn't be) introduced by the programmers of a proprietary program.

    The other benefit is one that is not yet realized. Why not integrate real GNUcash into the program GNUcash? A kind of "open source money" similar to Digicash or whatever. Not only would all the security concerns of the technical community be satisfied (untraceable, unforgeable, no key escrows or whatever) but while we're at it we can revolutionize the monetary systems.

Computer are cheap these days, and how much resources does a computer need to browse the net? Since nothing important is kept on the net browsing computer these security issues don't really matter much to me. And having to reboot periodically isn't a problem either, since all the real work is being done on a more powerful machine else.
