  1. Re:Textmate! on The Best Mac OS X Software Tools · · Score: 1

    Texmate found at http://macromates.com/ is wonderful. Take a look at some of the screen casts. Textmate is also very useful for editing LaTex documents.

  2. Goedel's Incompleteness Theorem and Independence on The End of Mathematical Proofs by Humans? · · Score: 1

    Mathematics is recursively axiomatizable by the axioms of ZFC. Goedel's Incompleteness Theorem says that the theory (the set of logical sentences provable from ZFC, i.e. mathematical theorems) must be incomplete. So there are some sentences that are not provable within ZFC. There can be no algorithm for deciding which sentences are unprovable in ZFC. Since most mathematicians don't care about independent sentences it is true that most theorems could be proven by computers - although at this time automated theorem provers are not very efficient. However for Logicians, and in particular Set Theorists, who do study such independent propositions (like the Continuum Hypothesis) do care to know what these independent sentences are and cannot be replaced by computers in studying them.

  3. Re:Mindless /. groupthink on 'Civilization on Mars' Claims Debunked · · Score: 5, Insightful
    Fundamentally everything comes down to the evidence and which theory best describes the evidence. The difference in the claims are that Hoagland indiciates that the best explanation of the evidence is that there is (was) an advanced civilization on Mars and that there is a vast conspiracy to conceal this discovery. That is a pretty extraordinary claim and needs some pretty extraordinary evidence to support it.


    Maybe this claim is true. Maybe it isn't. However since for the moment all evidence of this claim has explanations that are much simpler we are required to accept this simpler explanation that fits the evidence.


    We are skeptical, as science requires us to be. Extraordinary claims require extraordinary evidence and there doen't appear to be any such evidence for the moment. Furthermore the burden of proof is on Hoagland and others who make such claims.

  4. Making your own FOIA Request on Sci-Fi Channel Looks for LGM in NASA Files · · Score: 1

    If you would like to see these documents yourself you can go ahead and make your own FOIA request.

    Some instructions can be found at http://www.gwu.edu/~nsarchiv/nsa/foia/howtofoia.ht ml

    The contacts addresses can be found at http://www.usdoj.gov/04foia/foiacontacts.htm

    If you are interested in making the government work for you then issue requests! There aren't many easier ways to get government information that you are interested in.

    When you issue a request, the government is required to submit an answer within within 20 business days. Furthermore, if they deny your request they must give you a reason and you have the ability to appeal and or sue. If you are publishing the information you obtain for the public good you shouldn't even have to pay for the request.

  6. Re:Tip for Photography on Meet The Leonids · · Score: 3, Informative
    You probably fogged the film by not covering the viewfinder. With an SLR camera light can get to the film from the viewfinder. This is not a problem when you take pictures normally as your eye keeps light out. However when making long exposures with a tripod this isn't true. You should cover the viewfinder with the proper cap or something else when making long exposures. The web site mention in the article about making exposures probably mentions this but I cannot reach it at this time.


    Have fun! Remember to take different exposures (exposure bracketing) to make sure that you get a good exposure. Expose one stop in both directions from the calculated exposure.

  7. Re:Getting some industry back? on Japan Considers Moving Away From Windows · · Score: 1
    ... you haven't travelled by train from Mongolia to Russia. Apparently, there's this border station where they lift the cars above the ground with cranes and manually compress the wheels to fit the narrower Russian gauge.

    Actually the change occurs at the Chinese Mongolian border crossing at Ereen-Hot / Zamyn-Uud. The Mongolian rail lines were laid by the Soviets and hence the gauge is the same as in Russia. The Chinese track is narrower. Changing bogies is one of the reasons that the Trans-Siberian train takes more than three hours to cross this border. The Chinese PLA is the other reason.

    if his system works as he says it can, this will be quite an important milestone

    That should be IF and that is a huge if. Unfortuneately people have been making these claims for centuries and in each and every case they have been shown to be false. These people always claim to have a demonstration in just one week with a convenient excuse. Then there will be another demonstration and excuse in another couple of weeks. Repeat, lather, rinse. Not to mention the conspiracy theories that these people have. Everyone with an alternative energy device seems to be persecuted by a conspiracy of hundreds of people.

    They certainly put on a good show, usually with the intent of separating the spectators from their money.

    Why is it that these people are always able to violate laws of thermodynamics when no one else can? Why don't they get some easy venture capital by applying for the US$1 million prize given by James Randi Educational Foundation for demonstration of such an alternative energy device.

    They claim to operate their compound with another of these devices. I wonder if the power company agrees?

    From the FAQ:

    Why doesn't Blizzard provide facilities that enable these emulators to authenticate CD keys through Battle.net? In order for us to keep our proprietary CD-key algorithms secure, we cannot allow outside servers to query for the validity of CD keys.

    From a film made more than 20 years ago:

    INT. COLD STORAGE ROOM NIGHT

    Except for the work table with its sharp gleaming instruments, the room is as barren and sterile as a morgue. The glass-doored apartments in the walls look like crypts. Some of them small as post office boxes. From one of the Chew removes a vacuum, packed box. Carefully separating the seal, he reaches into the purple jell and with a pair of tweezers extracts an eye.

    Through the jeweler's glass, which he has not bothered to remove, Chew holds the eye up to the light and studies it a moment. His other hand searches through his pockets.

  12. Why would an American ride this? on This is IT? · · Score: 1

    Would you ride this to work instead of driving?

    I am car-free[carfree.org]. I do not own a car and I use a bicycle to travel everywhere. I use a bicycle to buy groceries, visit friends, go to movies, get to work, etc. I am very aware of the attitudes of many Americans towards their cars. Americans do not like to give up their cars for even the shortest trips. If you suggest that a person ride a bicycle the short 5 miles to work they in general will not even consider this. It is outside the realm of possibility and imagination. The car manufactorers have done a great job of equation the following:

    car = freedom = independance = success = identity

    Unfortunately a person without a car is someone to pity. I would love to see everyone riding around on bikes or this new mobility device. Outside in the fresh air, exposed to the environment, enjoying themselves and being a little more environmentally responsible. (Why does it take over 100hp to get a single person to work and back every day?!)

    I am not holding my breath. If people where that interested in traveling without cars why not use electric bikes?

    If you already owned a car (and you probably do) why would you spend another $3000 to not drive your car and be given funny looks by friends and co-workers, secretly pitied, and thought a fool.

    Unfortunately, having a car is an axiom for American life. For most American driving a car is a right dammit! (Or at least is should be) After all, without a car how would someone get around? There certainly aren't any other practical ways. Those guys riding bikes in the winter, rain and heat are just crazies. They only appear to be having a great time while everyone else is trapped and angry in their cars.

    Ballons float because they (the ballon, the pilots, the gondola, everything that is tied together) are less dense than the atmosphere at the ground and are the same density as the atmosphere at their ceiling.

  16. Re:Garbage: People rarely examine facts! on Disposable Cell Phones · · Score: 2

    I have to agree with your analysis generally, but you miss one important point. Most eco-freaks also support the elimination of nuclear, coal, natural gas, etc., power plants and instead support replacing those power plants with wind, solar, geothermic, hydro, and other eco-friendly power plants. When the energy is "free" (solar) the extra energy required to recycle becomes moot. The root of the problem is not recycling, but power consumption.

    Not to mention the fact that serious eco-freaks do not consume any fuel when they haul their bottles to be recycled; because they are pedalling a bicycle.

  19. Right to Privacy? on One for the Kids · · Score: 4

    Can someone please explain the American obsession with privacy? I cannot recall any enlightenment thinkers who explicit mention privacy as a natural right of man. It would seem to me that privacy cannot be a natural right of man. If all my actions were private then the contract I have with society (i.e. Locke's social contract) would be unenforcible. If society cannot determine that I have committed a crime because it violates my right to privacy then how can any crime be punished?

    It seems that privacy is not a natural right. Locke didn't mention it and, consequently, Jefferson didn't mention it.

    If privacy is not a natural right, then privacy is a priviledge granted by the society only when appropriate. As such, one does not have the right to absolute privacy.


    However, just because absolute privacy is not a natural right doesn't mean that privacy is not a good thing.


    Therefore, making an argument with the assumption that the right to absolute privacy is guaranteed is incorrect.

    I would like to official take respnosibilty for cracking the W2K test site. I used a new method called 'stealth psychic brute force' where by the sheer force of my will I was able to bring the site. It was my telekinesis that caused the lightning in Seattle that lead to this disaster. I personally willed the electrons along the path towards the machine. When these electrons travelled through the processor controlled by W2K code the crash occurred. If these electrons did not flow into the machine, it would not have crashed. I understand Microsoft is evaluating this type of attack and will release a hotfix to fix it. This hotfix is rumoured to recommend that the machine be unplugged in high load situations.

    I hope futurama has better writers than the Simpsons has had recently. The Simpsons is not as good as it has been mainly due to the poor writing, poor plots, and the characters becoming one-dimensional. I'm hoping that Futurama will have have the good writing, and great complex characters that made the Simpons so great. Even the name itself is pretty funny. "Futurama" sounds like something out of the 1930's world fair.
