    Let us suppose this lawsuit also eats four lawyers and the equivalent of one administrator year, for a total of 50 * 5 (fifty weeks, five days a week) * 40 (forty hours a week) * 5 (five people) = 50,000 thousand man-hours.

    You double counted the conversion from weeks to days, and double stated the thousands on man-hours. This should have been: 50(fifty weeks) * 40(forty hours/week) * 5(five people) = 10,000 man-hours. While this is still more than the 365*16*1=5840 man-hours that you could spend in a year if you spent every waking moment on the case, the difference in man-hours spent on the case is not as substantial as you make it out to be. In the end they probably can spend 5-10 times as much time as you.

    However, it's only 12.5% of a single day for them (not 62.5%), while it's every waking hour of a year for you., so your point still stands.

    My question is, if they're essentially the same, why do people insist on calling it stealing, even though they recognize that it's technically incorrect? The only answer I can come up with is that they're NOT the same, and people who call it stealing are choosing inaccurate language for a reason, probably to evoke an undue emotional response.

  10. Re:Why paging is necessary on 4Gb CF Card Announced · · Score: 1
    NOTE: for the duration of this response I use the definition of "swap" used in the windows "swap space" description, and recognize that the term "page" might be more appropriate. As this didn't appear to be a semantics argument, this seems appropriate.
    Uhm, you're (deliberately, I hope) misunderstanding the context. Swapping anytime is never, ever an improvement over never swapping. FreeBSD swaps out pages early and makes them available for other uses so it doesn't have to swap when it's under load. That's better than swapping when load hits the system, but far slower than just not swapping, i.e. having enough RAM in the first place.

    That's true, if you're willing to accept that the definition of "having enough RAM in the first place" is the sum of the memory requirements of all typically running applications as well as enough memory to store all filesystem data used by those applications. That's probably more than 4GB.

    Otherwise, there often is "a little bit" of almost totally unused program data that could efficiently replaced with disk cache. Things like `login` may always be running, but they're almost never actually doing anything on a server as they spend most of their time waiting on input or network connections. During that wait time, a little bit of swap would allow those programs to be moved off of memory to make more efficient use of that space.

    The easiest way to look at this is to think of a database server. If you've got a database with thousands of TB of data in it, then there is no way that you can fit the entire database in memory, even with several GB of memory. Sure, adding 256MB of memory is better than adding 256MB of swap, but the cost of adding 256MB of swap to such a system is basically zero, and allows the OS to make efficient use of existing memory resources. Adding more than that probably won't improve performance because most of memory will be disk cache anyways, but why have no swap space and deny the OS of the chance to make such optimizations?

    What it comes down to is: moving an active (CPU or disk bound) program to disk to make room for another active program is bad; get more memory in this case. Moving an inactive program to disk to make room for an active program's disk cache is good; this is just using existing resources more efficiently.

    I overstate my case somewhat, as there are reliability, development cost, and minor performance tradeoffs to implementing swap space, but saying it is NEVER a benefit is just not true.

    I was just looking at roystgnr's reply to your earlier post and it looks like that solution solves both the speed problem and the cyphertext/cleartext problem. This is probably why PCs do it like that.

    By encrypting just a random symmetric key you significantly decrease the amount of encrypted data available while at the same time increasing the cost of testing a decryption.

    As I said in my other post there's plenty of randomness available in a digital camera to use for creating the random symmetric keys, so this sounds like a good solution.

    This is more of a cryptography issue, and is clearly more difficult to deal with. Would adding some random data to the mix help? There's no reason you couldn't add some random bits to the cleartext if that makes cryptoanalysis more difficult. A digital camera certainly has plenty of sources to get randomness from.

    Either way, what does it take to not qualify as "weak-to-medium" encryption?

    Another option is to have a different encryption key for every camera that is put on the chip during wafer test, and whose pins aren't available on the package. This somewhat weakens the private key distribution security, but makes it so that one camera crack doesn't break all of them.

    Every time a shot is taken you write it to storage un-encrypted. When the camera isn't busy taking shots, it works on encrypting any photos that have been taken but aren't encrypted yet. This way you have to protect the storage or you're still distributing free CCDs, but that's not really the attacker you're worried about anyways.

    Not necessarily. This is an obvious candidate for public key encryption.

    Encrypt the pictures before you store them, and if you use a good encrytion algorithm, there's not much an attacker can do to reverse engineer the device. They could put a USB connection on the outside and it still wouldn't let an attacker get at the pictures.

    All that reverse engineering a well designed one of these devices will give a hacker is either of two things:

    A.) A cheap CCD and some optics. This is what happens if it's a two-chip design with the CCD on one chip and everything else outside the CCD chip.

    B.) Just some optics. This is what you get if it's a one-chip design with the CCD on the same chip as the encryption circuits. In this case the pictures go in the CCD and come out of the chip encrypted so there's not much the attacker can do.

    Either way there may be some other tricks to pull (like overwriting the encryption key), but there's nothing that prevents this from being hard-wired into the device and changed periodically as upgrades come out.

    Now, all of this neglects social engineering at the company, which may be the real weak point of attacking these devices. If an insider gives out the private key, then that could compromise all of them.

    The patent system is anti-competitive BY DESIGN. Can you think of a single product (medical products exempted) that society as a whole cannot do without for 20 years? If the patent holder makes unreasonable requirements for granting a patent license then you just wait 20 years for the patent to expire and THEN build one.

    In cases where selling the product is a natural monopoly, then it makes sense that the first developer should be the one to get that monopoly. In other cases, they get monopoly power for 20 years, after which prices will drop and availability will go up dramatically as new manufacturers enter the market. Either way, a product is invented and made available to the public that might not have otherwise been invented. This is how the system is supposed to work, and it IS in the public interest.

    The problem is when you have a product (like SOME medical developments) that certain customers quite literally CANNOT do without. AIDS drugs are a good example of this. In these cases the inventor has a captive market and can charge quite literally whatever they want, while the customer doesn't have the option of saying no and walking away or waiting 20 years. In those cases, and only in those cases, does some sort of compulsory licensing make sense. The licensing has to be done in such a way as to allow the inventor to recoup design costs plus a reasonable profit, while making the invention as widely available as possible. As such, compulsory licensing would probably have to be handled on a case-by-case basis.

    And, as I said, litigation is a totally different matter, as it DOES stifle legitimate innovation, due mainly to the granting of a lot of obvious patents that are then infringed in ignorance by others.

    While I'd agree that patents are a good idea, there are particular problems with patent system as it works now, especially in the USA.

    * It is too easy for someone to get a "bad" patent; i.e. one that is overly broad, for an obvious "invention", or for an "invention" for which prior art exists. You could blame USPTO for this, but in reality they are just trying to operate within their legal and budgetary constraints.
    * It is too hard to get a "bad" patent overturned. You have to resort to the Court system, which is far too expensive and time consuming for most SMOs or individuals to contemplate.

    Agreed
    * Once a patent has been granted, the patent holder is in a position to demand license fees that are out of all proportion to the true R&D cost of developing the invention.
    There's no particular reason why license fees should be in proportion to R&D costs. They should simply be based on the value of the patent, which is best determined by what an informed buyer is willing to pay. The problem here is when a competitor infringes a patent unknowingly, and when called on it is forced to pay exhorbitant fees to the patent holder. To me, not knowing (in one form or another) should be a valid defense, with reasonable expectations for when to pull products from the market (or set license fees) once you DO know.
    Here are some possible fixes:
    * A fast, zero-cost system for getting dubious patents reviewed and (if appropriate) overturned. The process should be triggered by complaints from the general public; e.g. based on reports of prior art, etc. Questions of "obviousness" should be assessed by independent panels of domain experts, rather than run-of-the-mill patent officers.
    I think the patent office is already doing this somewhat by opening patent applications up for external review.
    * Financial or other penalties for patent applicants who fail to mention prior art, or otherwise try to rort the patent system. Also sanctions for patent clerks who approve patents that are later overturned.
    Reluctantly agreed on the first part (really repeat offenders you're after here.) I disagree on the second part. That could just push things too far in the other direction.
    * Patent lifetimes that match the timescales of the industry in question.
    This is very hard to quantify. RSA was in the computer field, which arguably should have made it a very short-lived patent. However, it was also EXTREMELY innovative, so the 17-20 year timespan seems reasonable. Timespan really isn't the problem with patent law like it is with copyrights. 20 years is a reasonable timeframe for any truly non-obvious patent.
    * A legal cap on patent license fees (or damages) which is based on the audited R&D cost for the invention ... NOT the "loss of earnings" due to having a competitor.
    I disagree completely on license fees. When the two parties enter into an agreement in good faith, it tends to be an equitable one. This way the person wishing to use the patent can decide whether to use it or not in their product, based on the fees that the patent holder is willing to license for.

    On damages, the best thing to do is probably to allow ignorance in some form to be a valid defense, with a reasonable timeframe to remove products from the market once the violation has been discovered. If implemented correctly (I.E. it doesn't work to remain intentionally ignorant) this could be a good way of handling these types of problems.
