    So, if we could build an ARM-powered human, it could solve the Rubik's Cube in 2-3 seconds?

    Yes, but if you wanted to you could probably build a high speed, high precision tool to solve it in way less than a second. It's Lego after all, it's cool but it's not exactly built for performance.

  2. Re:Security is about preventing unintended outcome on NSA Says Its Secure Dev Methods Are Publicly Known · · Score: 1

    Some simple things that languages can do:

    - Have all variables initialize to known values. I mostly program in C++/Qt and QString, QByteArray etc. don't need initialization. All numbers should initialize to 0, all pointers to NULL.
    - Don't make the difference between assignment and comparison be a simple typo. If I were to design a language, "=" would not be a valid operator. ":=" for assignment, "==" for comparison. (You could keep all the "+=" etc. but not plain "=")
    - Smarter scoping hints, like letting you call a function and *pass* the variable, which ends its scope.

    Keep functions less than 1 page long. If you can't see the entire function on a single editor page, it is too long.

    In my experience that is not practical and leads to too many artificial functions. But you should try reducing the complexity of how many different variables get involved. It's easy to read a three page function if only things are scoped out properly so only the important variables stay in scope. E.g.

    void longFunction()
    {
    int foo = 0;
    { // 10 lines of code to calculate foo, some various temp variables etc.
    } // Here only foo is left in scope
    }

    This is only possible, as staff have suggested, because pretty much everyone either transfers an insignificant amount of data or practices restraint. If even a sizeable minority were to take unrestrained advantage of the Internet's wealth of multimedia resources, as has been increasingly happening with mainstream ISPs, the ISPs end up introducing fair usage policy/caps/throttling/traffic management (sometimes not revealing this last until a few technically minded people demonstrate it).

    If the norm for what is "normal" to use on an unlimited line changes, then the company should change their oversubscription, not add more (*) conditions. This whole thing is created by having one product, even though we know the profitability varies greatly and trying to "clamp" it so the unprofitable ones can't actually use it as advertised. If you want a "Value" subscription that isn't like the "Unlimited" subscription, then go for it.

    They've tried that here, everyone went for the cap-free subscriptions so that the others eventually died off. You might argue that the market is acting irrational in subsidizing the bandwidth hogs, but there you are. What's funny is that here the Norwegian companies are free market, and the US ISPs are socialist. Yes, that's what they are. "Please use only what you need, restrain yourself, be fair to the rest" is pretty much one half of "From each according to his ability, to each according to his need". For corporate profits of course, but that is the appeal.

  6. Distance? on Dutch ISP Demos Symmetric 100Mbps DOCSIS3 · · Score: 0, Offtopic

    So far the problem with DSL has been that the longer from the central you is, the lower the speeds and it drops quite rapidly once you're more than a couple km from the central. I would think it is the same for cable, since that too is based on electrical signals. With fiber you don't need a repeated more than every 70-150 km, meaning you can lay FTTH almost anywhere without worrying about it.

  7. Re:So then what you are really saying on NVIDIA's New Flagship GeForce GTX 580 Tested · · Score: 1

    1) The OSS heads didn't appreciate how damn complex a graphics driver is. You have people who'd written SCSI drivers or something and said "Well that isn't that hard." They forget that a binary SCSI driver is around 20k or something, you are dealing with a simple device. The main ATi Windows driver is 7.6MB and that is just the central driver, never mind all the support files it needs to work right. It is a major job, and the hardware changes fast.

    The biggest and foremost reason Linux support has been slow is that the graphics stack was very poor. Before AMDs announcement the only open source player was Intel who honestly nobody used for more than getting a picture. Since neither nVidia or AMD gave out any detail on their hardware and instead rolled their own closed source drivers, the open mesa stack basically still worked on a model from the 90s. If it had only been to drop AMD support into a modern 3D stack, we'd be much further than we are. Pretty much every aspect like 3D (classic -> gallium3d), memory management (classic -> KMS), modesetting (classic -> KMS), rendering interface (dri -> dri2), 2D acceleration (??? -> EXA) has changed.

    Even though AMD is making certain things open source, they are walking on eggshells with regards to other things, particularly giving away business information and DRM. Many of the things that have been given in code drops have been "code first", things that are only documented afterwards and often in very terse ways you couldn't write the code from. That also effectively bars a lot of code sharing between the drivers. Sitting on the outside it's been pretty tough to understand what is going on, and for the same reason many things happen in unpublished branches that are still waiting for AMD IP review. It's very much an one-way street because it's not the real "master" branch with the work in progress, it's more like wrapped up releases.

    That said, there is a lot that could be done on mesa itself. Anyone who could get full OpenGL 3/4 compatibility in the open source drivers would be a hero.

    In fact a case can be made that apps that include a click-through EULA of the GPL violate the GPL. Since clicking I disagree will refuse to install the app which is an additional restriction (section 10).

    I consider those a little bit like the reading of your Miranda rights, they're not *given* to you by the reading. They're rights you already have, it's just giving you a summary of them. Same with the GPL, the part about not accepting is basically a short reading of copyright law. Perhaps the acknowledgement that you have been given notice of this should be slightly different than "I agree", but you're nitpicking on something no judge would substantially care about.

    Zynga seems to be doing fairly well with their "I don't f***ing want innovation, you're not smarter than your competitor. Just copy what they do and do it until you get their numbers." policy.

    Ultimately a lot of things are done right and they just need copying. If I were to build a car, I don't want a new braking paradigm for my semantic car. I'd like a pedal that stops the car when I push it, and it has to do so reliably and consistently. And it doesn't matter if you have a new and innovative seat that gives me a back rub while driving until that is working.

    A lot of the things people struggle with are not some form of design choices. It's things that don't work, plain and simple. Of course a lot of people will tag this WORKS4ME, so the problem doesn't exist. I'm not sure whether Ubuntu is making any progress on their papercut project, but the name is at least good. It's not massive missing blocks of functionality, technical users get by. But it's full of crazy little hacks and workarounds and tweaks that kill it for the normal user.

    The difference is that most workplaces I've seen have a little system to set you up, show you the ropes and so on. Need not be more than an experienced developer but someone who can explain a bit of the hows and whys, and most importantly someone who you can usually get a little attention from. I've been trying to get "into" a project now for some time, but it's damn hard code to understand and in the beginning I am more of a bother than a help asking all these questions, trying to wrap my head around the code, parsing the logs and how everything hangs together. Many OSS projects aren't willing to make that effort, if you're not able to jump in and contribute from day one you go largely ignored, while nobody will let a new employee sit there burning money in the same way. If workshops like these will keep you from having to ask the most n00bish questions and getting RTFMs slapped in your face, it's good for everyone.

Even with that hardcoded in Xsetup, half the time it seems to not put the main panel on my primary monitor so I have to go into panel settings and drag it back where it belongs. It also has substantial trouble waking up both monitors from sleep, sometimes only waking one leaving me with half a desktop while the other half still says no signal. A simple disable/enable cycle doesn't work, but I've found setting it back to clone mode will make the other monitor wake so I can set it back. Maybe some of this is KUbuntu specific but it's not very impressive at least.

    Their primary protectionism is keeping their currency artificially low, which makes exports cheaper ahd imports more expensive. The US could do the same, which would help the domestic economy but it would lower the value of the almighty dollar. When you have a huge foreign debt, that would also make the interest much harder to pay. I suppose other interventionist steps might work, but if you heard anger about the bailouts I'd love to see how this would not become corporate welfare.

    The rest of the world is evolving rapidly into highly educated, highly industrialized, highly technological countries that resemble the west - in certain parts and certain ways, anyway. The more similar their productivity is, the more similar standards of living they can demand but for a long time a series of favorable conditions and network effects have kept the US in a solid lead. The balance is shifting, but to say that it actually flows from one country to the other is fairly misleading. You could halt trade but it wouldn't halt these countries from modernizing, and they would also retaliate.

    The US currently has a very negative trade balance, meaning it imports far more than it exports. If it were to close the borders, the US would hurt the most. Medium to long term that could mean opportunity for domestic industry, but the short term would be a substantial drop in the standard of living as many goods become expensive or even unavailable. There was a time when a trade boycott with the US would be dire but today if you can maintain trade with the EU, Japan, China, India, Taiwan, Russia and so on most countries would do fine. Alternate suppliers of almost everything now exist outside the US.

    In short, the US is no longer in a position where they would have anything to gain from going protectionist. They'd be their own little isolated market of 300 million people while the world market - even subtracting the billions that are too poor to really participate - is much larger and would simply outpace the US.
