  1. Re:Ubisoft : DRM isn't about piracy but used games on Blizzard Boss Says Restrictive DRM Is a Waste of Time · · Score: 1

    And here Blizzard has a trick : WoW requires a monthly fee. So used games resell aren't a "threat" to its income.

    I haven't seen anything that indicates that Diablo III or StarCraft 2 would require any kind of pay account.

    Sure, you might need a battle.net-account, but there are no requirements for payment of any kind.

    To be sure, I just created a new one. I own no Blizzard games. But I could still create an account. No requests for credit card or other payment options, no questions about what game I own (i.e. CD key) etc.

    There IS a chance, that once I've added a game key to my account, I can't remove it afterwards, but since I don't have an account, I can't say for sure if that's the case. I also don't know, if you can have a key attached to multiple accounts.

    But Diablo and Diablo II had none of those issues.

    It was always ... odd to see the space shuttle consume vast quantities of booster fuel to hover stationary above the earth before pulling away slowly.

    I suspect that's simply because of the amount of outside air, you'd need to pull in to fuel the engines otherwise.

    I only have enough of a clue of what it might involve to redo the calculations, that I know I haven't a clue. But I really do believe that available oxygen is the limiting factor.

    NASA says they use 500,000 gallons of liquid hydrogen and oxygen. Liquid oxygen weighs 1141 g/L and 16 g/mol. This gives us 71.3125 mol/liter. That means for every litre of liquid oxygen we need 142.625 mol liquid hydrogen. Hydrogen is 1 g/mol and liquid hydrogen weighs 67.8 g/l so we need 142.625 grams of hydrogen which is 2.104 litres. So we have a 2.1:1 ratio.

    This gives us about 162.000 gallons of liquid oxygen. That's 613,000 litres or about 43,523,000 mol of oxygen. Oxygen at surface pressure and 0C weighs 1.429 g/L. It's still 16 g/mol, so one litre of oxygen contains 0.089 mol. So we need 487.300.000 litre of pure oxygen. And since air only contains 21% oxygen, we'd need 2.320.000.000 litres of air, at 1 atmosphere and 0C.

    It takes the shuttle 9 minutes to have spent all the fuel in the external tank. That means we're looking at around 4,296 m^3/s, just to supply that much oxygen. The three nozzles are 2.4 m in diameter. This gives us a total engine "surface area" of 13.6 m^2. If we assume the intake nozzles are the same size, the air would have to move at 316 m/s to supply it.

    Obviously - if we remove 700 tons of liquid oxygen, we reduce the mass required and so on, and my back of the envelope here doesn't account for that. That's why we have rocket scientists.

    But it's a fun thought.

    Can a scramjet reach escape velocity

    If it is capable of propelling whatever it's carrying to 11.2 km/s (just under Mach 33 at the Earth's surface). Since this one only goes to 6, there's still a ways to go.

    Just as a foot note - if you're travelling at 11.2 km/s in a circle with a 6,378 km radius (Earth's equator), you will experience an acceleration opposite to gravity of 19.67 m/s^2 (aka 2 g). Just slightly slower if you do it at an altitude of 10 km (19.64 m/s^2). At the altitude this one reached, you'd hit 19.6 m/s^2

    It's not a waste of time nor resources, if the time spent is that of a PR person who simply has to forward a (bunch of) video to scientists, and the resources spent are those of people who aren't otherwise occupied with this. Like, for instance, scientists who aren't useful for fieldwork.

    but the environmentalists don't want us to use nuclear power because.... actually, I've never really understood why.

    Because the waste products are highly toxic, needs high levels of security around them because OMG terrorists, needs to be kept safe for millennia and they don't like the idea of having a Chernobyl type malfunction in their backyard.

    Now, some of these complaints are valid - the waste from the plants we have now isn't exactly something you can just stow away until it's composted in a hundred years, like you can with most types of regular landfills. Same with security and long term prospectives.

    Chernobyl type plants aren't built in the west, so that's an irrelevant complaint. Might as well complain that cars are really unsafe, because the Ford T had no kind of passenger protection.

    Waste is still an issue, but it can be solved. Not with the current types of plants, as they only use a tiny amount of the total fuel, leaving behind long lived radioactive waste. Change the type of plant to something like Thorium (Google tech talk), and maybe we don't have that waste issue, or rather, we have reduced the amount of waste. Less waste means easier handling. And security wise, we might want to consider subduction techniques, though I'm not sure if that's feasible.

    However, getting political (and thus financial) support for a new type of nuclear plant is generally tricky in the west, not to mention that fanatics don't really care about arguments or logic, and the anti-nuclear lobby tend to be rather fanatic.

That's 3.2% of the Earth - which, to my mind, qualifies as a sliver.

    How the hell did my mention of some cutting edge cosmology hypothesis lead to a creationism debate

    I didn't realise that discussing the possibilities presented to us by natural history and evolution was akin to creationism. But that might not have been aimed at me.

    Yes, erm - no mammals ever saw one, the earliest mammals were the Morganocodontids, who did live before the K/T event, but not THAT long before. Pterosaur is as far in the past of the earliest mammal as Tyranosaurus is in ours

    According to the evolution of mammals page, the earliest known marsupial, Sinodelphys, appeared 125 million years ago.

    And Pterosaurs existed from the late Triassic to the end of the Cretaceous Period (220 to 65.5 million years ago). That gives us an overlap of about 60 million years where mammals and Pterosaurs co-existed.

    every culture, every dragon story get the same basic body shape. A creature that has four legs AND wings. A vertebrate with six limbs

    Not correct. The Chinese dragon very rarely have wings, and when they do, they're essentially bat-like in that they're extending from the front limbs. They also don't breathe fire. Same with the Japanese dragons. In fact if you look at the Dragon article, only the European ones have wings. And even the article on European dragons have very few mentions of wings.

    That's actually surprising to me. I thought only the Chinese dragons were wingless creatures. And interestingly enough, a lot of the dragons in the European article have only four limbs - i.e. if they have wings, they don't have four legs (making them Wyverns). This made me curious, and looking at the Saint George and the Dragon article, a lot of the drawings/paintings do not show the dragon with four legs plus wings. This is odd, because they alternate in age. I.e. Saint George and the Dragon, by Rogier van der Weyden is from the early 1400s - two legs plus wings. Then Lyfe of Seynt George (Westminster, 1515) shows four legs plus wings. And Saint George and the Dragon by Gustave Moreau mid 1800s has two legs plus wings again. The treatment by artists list also shows a mix, though the earliest all seem to show a Wyvern.

    I don't think Dragons ever existed (cool as it would be too be wrong)

    I agree. But the post I responded to was talking about going to a dimension where Dragons did exist. My post was about the posibility of this from the perspective of what we have seen possible in our natural history. And nothing really stops the dragon from being a flying lizard that can breathe a fire-like substance. Size wouldn't nescesarily be a problem either ... get the air dense enough and rich with oxygen and you could have them huge. Pteranodon managed a wingspan of up to 9 meters (no weight estimates though). It's still a long way to what most of us here think of when we say Dragon (i.e. Smaug or one of the ones from Reign of Fire) though.

    I've been thinking about long term storage solutions for a while, and if we're looking at solutions that would survive floods, EMPs etc., pretty much all methods we have available today are done for. Also they require access to readers that may be ruined for whatever reasons.

    Essentially I keep coming back to punch-cards or similar. Not into paper, but into something like anodized titanium. The colour spectrum available there could allow something like 4 or 8 bit encoding per dot. Not entirely sure about how small you can make the dots, nor how close together you can put them if you want more than just two colours.

    It'd be somewhat human readable, in that you just need a microscope to view the dots, and then it's just the usual translation method of course. And you could store a simple "dictionary" of cards with large dots + words/characters to make it easy to translate (a Rosetta Stone). And since it's titanium it's unlikely to be affected by the usual disasters. It doesn't melt until 1,668 C, so it's probably going to be quite stable in most types of fires, it pretty resistant to acids, the anodizing should go through the metal, so even sandblasting it won't remove the information (unless you cut through it of course).

    Depending on the size of the dots, I think you could even make a simple credit card sized object, that you could show to a web cam to use as a private key for private/public key encryption, logging on to your workstation, getting in to a secure facility and so on.

    And if done properly, you could probably disguise the key if necessary. You can already get custom backs/covers for your iPod/iPhone. Why not get one with this kind of back on it? Hide the key via something like steganography, making every n pixel a part of the key.
