Its not quite as easy as just swapping out schemes. As I understand it a practical quantum computer would break all proposed public key encryption methods except those based on lattice problems. Lattice based…
The original IBM press release says "a single 250-qubit state contains more bits of information than there are atoms in the universe." Then the author tries to rewrite the press release but in this case what probably…
The discrete and continuous transforms are closely related. DFTs and their properties were known before Gauss and his 1805 paper is about computing them quickly. I wanted to emphasize the difference between the problem…
Not to detract from Gauss' remarkable discovery but there is no relation between Gauss' FFT algorithm and the continuous Fourier transform that Fourier discovered. It is also worth mentioning that credit for the…
The difficulty of the discrete log problem doesn't have anything to do with the modulus being prime, DLP is at least as hard for composite moduli. Its considered a hard problem because after 30 years a fast algorithm…
The method used in that article is just counting flight incidents in some historical data that may possibly have been caused by interference. The evidence that consumer electronics are the cause is just anecdotal: "In…
You are saying the author should write differently depending on whether black people are reading the comment. Is that really what you meant?
I think the comparison should really be between Quora and the whole Stack Exchange family of sites. I think there are two main reasons many of the areas in Quora are useless. First, Quora never got commitment from a…
"With rare exceptions, people like Bill Gates and the engineers of Silicon Valley didn’t get their interests from a modern K-12 education." Yeah, guys like Bill did amazing things compared to those bozos that just took…
The author is totally unconvincing. Creating tags splits the problem of asking or answering into 2 parts. First, search the space of tags to find the one you need. Second, search the space of questions with that tag.…
I don't think photos are the main attraction anymore. I know lots of people that only add a couple of photos a year to Facebook but still visit the site every day.
Do you know anything about American Apparel? You'd be better if with your money in a mattress than in their stock.
Take home point is that merchant satisfaction is not a priority for Groupon. Their strategy is to try and get customers to stick. How is that going to work? Clever ad copy and ridiculous deals aren't going to keep…
Also why does the title have nothing to do with the point he is trying to make?
Its a weak counterargument to Scheiner's. The ability to think logically (one example of which is writing proofs though I think writing good code requires it as much) is no protection against attacks you don't know…
I wouldn't take that as changing the odds of correctness. Collatz stated the conjecture but made no progress towards a solution.
The point was that for Groupon the revenue numbers are meaningless not that the example business plan can't work.
The barrier to entry for Groupon competitors is low and there is no cost for both consumers and local businesses to switch to competitors. Based only on that I don't see much hope for them long term.
Its a good first approximation so to a physicist it might as well be true.
