    How do you define bad code? I define it as producing erroneous results. But if your in a compute bound application, and the cost to upgrade hardware looks formidable, then you look at optimization. In my world, I look at optimization first, and hardware upgrades as second choice.

    There are sure hours and hours of test cases for the work was done for optimization. The author looked at employing math factoring, not in designing new hardware. Great!!!

  2. Re:not just many eyes on 2014: The Year We Learned How Vulnerable Third-Party Code Libraries Are · · Score: 1

    The security of the open source model isn't really the problem or the answer here. The problem is homogeneity. A million different sites and applications rely on just a few libraries, so that when a bug hits one, it has massive impact on the entire internet.

    We also know that the answer isn't in rolling your own security. Very few people or organizations are likely to be able to securely implement their own version of TLS. Even the best packages of today didn't start out perfect, they had to iterate through several flaws to get to where they are today.

    So perhaps the better answer is in having more packages to choose from? Instead of picking just openssl by default, it would be better to have a broad array of choices. With a dozen packages on the market, that might mean 11 times out of 12 the bad guys wouldn't exploit our site. If the packages are interchangeable, we'd be better positioned to switch them quickly in case of emergency.

    Today, disk space is very cheap. Memory is very cheap, and I think nothing of having 32gigs of ram. My point-- do away with dynamic linking for your application. Do static linking, except possibly for display libraries. If a flaw is found, its going to require many recompiles, but that is offset by the non-reliance of multiple dynamically linked libraries. As was mentioned, get a flaw or security issue with that library, or create a "man in the middle" attack with one dynamically linked library, and voila, your security is compromised. With static linking, your application is more secure and is known to work with more versions of the operating systems

    We need an entirely new model of encouraging invention. Trade secret is useful in providing a reasonable profit window and establishment of precedence in the marketplace (the only way to go with software, as far as I'm concerned) as the window you get correlates well with the complexity of what you've done, but has its limits when we're talking hardware.

    Perhaps a way for society to pay for an invention, and once that's been done, it goes right into the "available to everyone" pool. Panels of experts setting perceived value and an immediate payment being made, followed by a revisit ten years later to determine how it all went, with extra reward possible if the invention's impact was underestimated?

    Look at me, suggesting government committees. Oy. I should go bang my head on a table.

    But damn, we *really* need to clean out the drains. Patents are the disgusting glop that are making the system run slower and slower, while getting legal sewage all over everyone involved. The only consistent winners here are the plumbers (lawyers.)

    I don't consider algorithms to be patentable. But I consider a process to be patentable. What is the difference? An algorthim is an application of a set of defined rules that presents a proof, a set of steps to follow to a solution. An algorithm may be copyrighted. A process is a application of a set of rules to define the control or manufacture of a product. (Driver for hardware, agricultural process, or manufacturing process, fabrication process). If we deem an algorithm a process, then the writing of a book has to be patented.

  14. Actually the opposite is the case. Our economy has exactly the opposite, but nonetheless equally destructive, problem communism had: They had a shortage of supply. We have a shortage of demand.

    Our economy produces enough. Proof? Go anywhere and behold how desperately everyone wants to sell. Be it goods or services, You'll be hard pressed to NOT find someone offering whatever you may want to you. What's lacking is the demand. And without it, there is no market either.

    If you think people need any kind of incentive to be ravenous asshole capitalists, think again. Those that could invest already want to. Quite badly, too. There just isn't anything to invest in, because there is no viable business possible without consumers that would want to buy what you'd offer. And the main reason for this is simply that there are not enough people who have enough money to become consumers. And jobs are sadly not created when someone wills a business into existence. Well, you can do that, but it's not really viable to produce without a chance to sell what you produce. You'll be bankrupt in no time.

    A job is created when the market situation of demand forces the supply side into hiring additional personnel to fill that demand. Nobody in their sane mind creates a job for the sake of creating a job, paying another person and putting more goods he can't sell on the stockpile. If this is the situation (and that is the situation currently), the sane option is NOT to hire someone and NOT to produce more of what you can't already sell.

    In the case of Intel trying to break into tablets, my understanding is that it's a known matter of fact that Bay Trail parts are being practically given away(along with a nontrivial amount of Intel software work, including an emulator to handle ARM NDK stuff and general porting and polishing to make the x86 Android not look like, say, the blasted hellscape that is MIPS Android); but it is less clear whether Intel has been able to dump hard enough to actually damage competition.

    The one product line that they definitely helped bury was Windows RT (which was mostly an unloved bastard child anyway, even before you could cram an x86 into the same chassis, and definitely had no reason to exist afterwards); but that didn't hurt MS much, since the quality of Windows tablets went up. In the wider ARM ecosystem, ARM Ltd, themselves seem to be riding high and unbelievably cheap SoCs continue to pop out of the woodwork.

    Their Bay Trail pricing has definitely made x86 Android something you might actually see in the wild, and tablet-Windows something you might actually consider at a sub-Windows Surface price point; but it doesn't seem to have crushed the ARM market very much.
