    I'd rather have them keep the uncompromising, legendary quality instead. I encountered exactly 1 bad brick in 10000$ MSRP worth of Lego. I think the fact that the set will not break or wear out in 5, 10, 15 years is a big consideration for families which have more than one child. I have a lot of Lego bricks that survived my entire childhood and are still in very good shape, even though I used to play with them very frequently.

    So they've managed to stay in business by the power of marketing and the irrationality that people display when buying for kids.

    They actually created a product that people want to buy. Is that a bad thing? Coupled with the fact that you can still buy the 'unbranded' sets and that they are reducing one-off non-reusable pieces, it's a good thing.

    Have you seen what a lego set costs these days?

    There is a reason. The quality of Lego is legendary, so much that they don't even advertise it any more. The parts are manufactured to tolerances comparable with precision machinery. For example, when you place 10 bricks with holes side by side, you can run 12-unit axles through each of the holes, and they always align perfectly. In a new set there are no bricks that don't "stick" together, and the plastic wears down really slowly. I have encountered exactly 1 bad piece in 10000$ MSRP worth of Lego (and they replaced when I e-mailed the customer service).

    It's no wonder cheap rip offs that don't even work as well are getting a slice of the action.

    Poland is not a very rich country and yet Lego still dwarfs all other brands combined by sales volume... I don't see too much "action" for cheap imitators.

  10. Re:We just need an alternative to X on Kernel 2.6.31 To Speed Up Linux Desktop · · Score: 1

    X is not a problem. X is actually one of the best parts of the Linux graphics stack, and it allows very nice things like running graphical applications remotely. Moreover, DRI allows applications to bypass the X server entirely. The actual problems are the drivers, and a lack of standardized APIs for things like video acceleration that work regardless of the card manufacturer. However, this area is slowly improving, for example take a good look at Gallium3D. When this matures, the amount of effort required to implement a video card driver will be greatly reduced; OpenGL, OpenVG and all other graphics APIs will be implemented in the Gallium3D stack, and the Gallium3D driver will be comparatively simple.

    Duh, that's trivial. The hard part is integrating with other languages, which GObject does perfectly; most bindings for GObject-based libraries can be programatically generated. That's why most people writing a new language go for GTK bindings first.

    Yeah, but bindings somehow manage to exist. They may not be trivial or small, but unless you are the binding author yourself you don't need to care that much.

    More complicated bindings = more bugs and lower performance.

    Same can't be said for GObject - stable C ABI sounds great, but the development is still very painful and annoying and you start wondering whether it's all worth it.

    If you don't like C boilerplate, you can write in Vala, which compiles to C sources and therefore preserves all he benefits of GObject while giving you a modern language to work with.

    Hydrogen is not actually much lighter than helium. What matters is not the molar mass, but the difference between the molar mass and the average mass of air - this is what generates buoyancy. Hydrogen is 2 g/mol, helium 4 g/mol, air approximately 29 g/mol (it is a mixture, so that's the average value). Ths means that 1 mol (about 22,4 l) of helium will lift 25 g, and 1 mol of hydrogen - 27 g. Therefore hydrogen is only 8% better than helium.

    It is notoriously hard to work with power management features of notebooks, because it is hard to find a really ACPI-compatible BIOS. Most of them are broken in some way, or require undocumented voodoo and magic values to behave. There is really no solution to this unless: a) Manufacturers get their shit together and ship functioning hardware, not hardware that accidentally happens to work under Windows (systemic approach); b) Linux gets more mindshare and those issues get sorted out on a per-device basis (band-aid approach). a) is very unlikely, since shipping functioning hardware brings no obvious reward to the manufacturer. Therefore we can only hope for b).

    Note that this is not limited to ACPI. In almost every area, there are hardware products that do not comply with specifications they are supposed to comply with, lie about supported features when probed, have bogus device descriptors, reuse the product ID of a different device, do stupid things when supplied valid commands it doesn't expect, etc.

It doesn't mean "only the incompetent use violence as the last resort", or "wars are wrong and everybody should love each other". It is not a pacifist maxim; It's more a reflection on the means of conflict. It means "if you use violence, it will be the last thing you do, and will prove your incompetence to handle the situation". The Foundation books made it clear that Asimov's definition of violence did not include things like armed deterrence, espionage, psychological manipulation, or even assassination if it meant avoiding a large scale conflict. It meant direct physical violence that results in death of people or destruction of property. In that light, violence is a proof of incompetence, because a competent leader would be able to take over the people and property to use them to his own ends, rather than destroying them.

    Someone's missing the point of net neutrality.

    Net neutrality means: if I have network access, and some guy has network access, we can connect; the ISP treats my connection the same regardless of WHO I'm connecting with. It doesn't mean the ISP cannot differentiate the quality of the connection based on HOW we connect.

    This is something else: they are varying quality based on HOW they're connecting to others (what protocol). Note that it's not an outright ban, only a rate limit in order to prioritize of HTTP traffic. The only problematic part is the throttling of upload-intensive services. However, it is not a net neutrality issue as long as they are throttling solely on the amount of bandwidth consumed by a service, rather than who pays them most money to have his service unthrottled.

    Remember: Net neutrality is not about unrestricted BitTorrent for everyone. It is about the Internet not turning into cable TV. It is about stopping ISPs colluding with content providers so that they can charge you or deny you access to your favorite websites, in order to ram their own inferior ad-infested versions down your throat. It is about being able to connect to everyone without seeking permission of your ISP or paying extra. It is about Internet access being a binary variable: either you can connect, or you can't. No limited service plans where you can connect only to the ISP's webmail and search engine, and all other webmails and search engines are blocked unless you 'upgrade'. No 'premium sites' you can only use if your ISP has a deal with the content provider that you cannot opt into or out of.

    If you are dissatisfied by your ISP blocking or throttling your favorite website or service, by all means complain. But do not conflate traffic shaping with net neutrality. It muddles an already complex issue, and harms our chances to win this battle.
