    you have obviously not shopped for groceries anywhere other than NYC.

    Prices are usually 50%-200% higher here for groceries in my super market in Queens compared to grocery stores in San Antonio, Texas where I am from. And it is the cheapest one around that I found.

    Of course things in general cost twice as much here compared to San Antonio. rent, housing, gas (well about 25 cents more), groceries, labor, driving (tolls vs no tolls), movie tickets, a night out at a reasonably nice restaurant (not even something fancy, just not mcdonalds).

    The 2 big ones, labor + real estate costs are going to be a huge factor in the price of food at a super market compared with whatever small discount they might receive from a shorter distance from the port to the store. Not to mention that the US is a net exporter of food last i checked so not much of your food come in a ship from over seas, but a truck instead, though possibly and often from as far away as california.

    Please let me know where you are finding a cheap grocery store in this city. Ditto for cheap anything.

  4. Re:Unconstitutional on Time To Discuss Drug Prohibition? · · Score: 1

    Previously, the 18th amendment banned it, so the only way to lift the ban was to repeal that amendment... with another amendment. Both texts are still in the constitution.

    http://en.wikipedia.org/wiki/Twenty-first_Amendment_to_the_United_States_Constitution

    Having not read either of these wiki articles, I'm not sure why the constitutional amendment process was used to ban it in the first place instead of just a regular act of congress. Probably because at the time the interstate commerce clause http://en.wikipedia.org/wiki/Interstate_commerce was not as powerful as it is today (it gained its power in supreme court in the fight over FDR's new deal I believe which is after the prohibition era)

    I think you might be underestimating the power of the human brain. From wikipedia (emphasis mine):
    http://en.wikipedia.org/wiki/Human_brain#Comparison_of_the_brain_and_a_computer

    There have been numerous attempts to quantify differences in capability between the human brain and computers. According to Hans Moravec, by extrapolating from known capabilities of the retina to process image inputs, a brain has a processing capacity of 0.1 quadrillion instructions per second (100 million MIPS). In comparison, the fastest supercomputer in the world, called Roadrunner and devised and built by engineers and scientists at I.B.M. and Los Alamos National Laboratory, is capable of handling 1.026 quadrillion calculations per second[11], and an average 4-function calculator is capable of handling 10 instructions per second. It is possible the brain may be surpassed by normal personal computers (in terms of Instructions Per Second, at least) by 2030.[12]

    Or he could go to a public school and not pay through the nose... My total tuition was about $32,000 across 4 years. Half of which was paid for with loans and the other half paid for with various jobs I took while in school and during the summer.

    University of Texas BS in Computer Science, now I almost make $100k per year (first year out of school)... except its in NYC so that's like making 50-60k elsewhere hehe....

    I get so tired of the people I meet here in NYC who complain so much about their tuition and yet it was their dumb idea to live WAAAAY beyond their means and end up in 100k in debt just because they wanted to go to some famous fashion college here. Just today I was asked if I could house a friend for the summer while she was between apartments due to her lack of ability to earn money with her unfinished degree and her massive tuition debt(nearing 100k)

    Just go to the best school within a hundred miles if you are going to pay on your own. You will be better off in the long run. Unless you expect your earning power to increase exponentially over time.

    well maybe a few grad students would still be slow, but how about using Amazons Mechanical Turk to farm out the entire proof to be summarized in 10 page chunks.

    And why are we using software that sucks that much if its constantly performing the same thing over and over again and not able to notice that, then its pretty bad. I assume these weaknesses in computer theorem provers will eventually be worked out to provide shorter more general proofs while still not attaining the elegance of good human generated proofs.

  22. Re:I dont get it on Open Source Math · · Score: 1

    Hmm I didnt think of the gaps being so large, but I assume that is due to the computer constantly reproving things and not generalizing the proof enough.

    In this case the author should provide both the computer generated proof, and her edited "summary" version which she should have created anyways just to make sure the "proof" was right. You farm this out to a few grad students where they skim the proof and break it down into logical sections and label them. So the readers of the paper (i assume its electronic with 1 million pages) can skim through it too and examine the parts that might seem suspect to them.

  23. I dont get it on Open Source Math · · Score: 1

    Do these theorem gap proving helpers not produce a human readable proof? Or do they simply return T/F? Seems quite easy to build in a logging mechanism to keep track of how the proof proceeded in the software and then write a human readable, though probably quite ugly, proof. As long as the proof gets spit out in human readable form the "author" and the readers of such academic papers should attempt to follow the proof and check it for errors.
