  1. Re:Not of practical use? on Solid State Quantum Computer Finds 15=3x5 — 48% of the Time · · Score: 1

    As I said two posts above yours, it's not practically useful because factorising 4-bit numbers on a classical computer is already easy. Factoring larger numbers is hard, but requires more entangled qubits.

  2. Size, not reliability on Solid State Quantum Computer Finds 15=3x5 — 48% of the Time · · Score: 4, Interesting

    Validating the result is cheap on a classical computer. Even for very large values, multiplying two 4096-bit values together and checking the result is incredibly cheap. A quantum computer that could give the right set of divisors for a 4096-bit prime 1% of the time would still let you very quickly find which of the answers that it gave was correct. The limitation is the size, not the reliability.

    Free bread would be great. Most bread that people buy is based on quite old recipes. If people stopped creating new bread recipes, few people would complain. Those of us who bake bread at home would probably continue to experiment so you'd have enough new bread recipes being released to satisfy demand even without the profit motive.

    In the case of creative works, it's less obvious. Tastes and requirements change. There is not just a demand for music, for example, there is a demand for new music. The same is true of films and software. The problem is that creating new works is both hard and valuable, whereas copying them is increasingly easy, but the economic situation created by copyright means that you have to do the difficult bit for free and charge for the easy bit. As a car analogy, imagine if a car manufacturer decided that they were going to sell unpainted cars for free and then charge $10K for the paint job, then push for legislation that made painting your own car illegal.

    As author Charles Stross (meaning he has more gravita on this matter then you) observed it makes no sense to punish people who are your customers.

    I only have one data point in this from personal experience, but it supports Stross' view. Someone posted a copy of the PDF of my first book to a mailing list that probably 90% of the people in the target market are subscribed to. I saw a very slight increase in sales in the next royalty statement I got, although small enough to be counted in the noise. I certainly did not see a mass of lost sales because now everyone could get it for free. If I had to prove lost income from the wide illegal distribution, I'd find it very difficult.

    And, conversely, I have had people tell me that they bought my books in PDF or ePub editions, but would not have done if they had included DRM. So, in my anecdotal experience, DRM is far more likely to cause you to lose customers than piracy. I have no idea whether I am a special case or whether this is generally true.

    We should distinguish between someone who pirated a single copy of a song for personal use vs a person (or organization) who is willfully redistributing for profit.

    Why for a profit? From the perspective of someone trying to sell their music, it makes no difference if someone distribute 10,000 copies of their work makes a profit or not.

    I had to read your post a couple of times to be sure, but it sounds like you're actually not being sarcastic and think that's a good deal. You're paying $0.16/minute, and you're on a contract.

    There's a big difference between cell and power infrastructure. The power, once installed, needs routine maintenance. It's not a question of it not paying for itself, it's a question of it taking 20-40 years to get the return on investment, which private enterprise isn't willing to do because it could invest the same money elsewhere and get a more immediate return. In the case of rural mobile coverage, the equipment often doesn't get a positive ROI before it's obsolete, and then you need to pay again to replace it.

    When did advertising suddenly become evil, after 300+ years of being the main revenue source for most media?

    It started in the early 20th century, when it began to transition from being about making potential customers aware of your products to creating demand via psychological manipulation (see, for example, smoking adverts from before they were heavily regulated). It accelerated in the last decade when it became about building detailed profiles of individuals.

  16. Re:Just block all ads and don't worry about it on Ask Slashdot: To AdBlock Or Not To AdBlock? · · Score: 1

    I don't explicitly block ads, but I do run a plugin that blocks all tracking that it can identify and another that requires user interaction to run flash. I don't want that either tracking or auto-play flash from either things I explicitly visit or from adverts, so if you can show me ads that are in the same technical category as content, then that's fine.

    I also add a note in my user CSS file that flags links to certain sites that have adverts that I consider too intrusive. I then evaluate more carefully whether I want to click on links to them when they appear. If, for example, there are two links in a Slashdot summary and one has an obnoxious ads warning next to it, then I'll click on the other. It's a shame that there isn't a plugin that lets you do that a bit more automatically.

For the 2GHz i7, the MBA is $1,499, the ThinkPad is $1,849. However, the ThinkPad has a 14" screen instead of 13" (not sure if this is a pro or con in a portability-at-all-costs Ultrabook), integrated 3G (need a USB dongle for the MBA). The ThinkPad lacks Thunderbolt, so USB is the fastest peripheral interface. The ThinkPad is marginally larger in one dimension, marginally smaller in two more, so about the same volume and the weight difference between the two is under 0.1%. The ThinkPad comes with a 3-year warranty, but this costs extra for the MBA (unless you buy from the education store), which brings the cost quite a bit closer. The cost of upgrading to 8GB of RAM for the ThinkPad is not listed - it's not even clear that it's an option, which is a shame because that's something I'd be pretty sure to want.

    That's kind of the point. Motorola has NOT been offering patents to Microsoft and Apple at the terms they have offered to other people. (They want literally orders of magnitude more money for the patents.)

    If it were that clear-cut, there would be no lawsuit. Motorola is offering these patents under exactly the same terms that they offer to everyone else. These terms are a fixed percentage of the final device cost. This satisfied the Fair and Non-Discriminatory parts of FRAND. Apple is arguing that they are not Reasonable, because the same percentage of a $20 dumb phone and a $600 smartphone is a very significant difference for using the patents in exactly the same way.
