    With word coming out that they removed Natal's processor and it'll now use anywhere from 10% to 33% of the 360's own processing power, just how good will the games be? There's going to be a price in what developers can you do when you chop that much CPU time out of the system compared to a standard game.

    I don't think it will be a problem for games designed from the get-go to take advantage of the system, but it will limit adding the feature to already released games.

    It is how we use the technology that will be important. It might be a fad in games but this has so many other uses and might present a cheaper method for many people to enter into this field (motion control portion not the game portion).

    An interesting potential use is like TrackIR for head tracking and controlling the game camera. Especially for flight or driving games where it's inconvenient to use the right thumb stick to look around. I can envision other, similar uses to augment standard control schemes.

    1) Too bad you will have to leave your device in the path of that directional beam.

    Why does it have to be a directional beam? It can be anything from a beam to a pretty decent cone.

    Even a cone diminishes at an inverse-squared rate, it just starts more powerful. The measurement of an antenna reflects this, as it is simply a dB ratio of the power compared to a spherical-radiating antenna.

    Even if you have a 4W transmitter focused onto 1m^2, this receiver is no bigger than 10cm^2. You'd still only receive 1% of the power (40mW), and only if the receiver stays within that 1m^2 area, and that's also your WiFi signal. The point of WiFi is to let you access the internet in a way that lets you move more than 1m, so the idea is bunk anyway.

    You're still starting with too small of an initial power and losing too much of it to be of any practical use even if you design the system to take advantage of it, let alone in a random public location.

    Because a lot of that advantage is gained by the gas generator running at an efficient RPM for power generation. The car would still need a bank of batteries (or maybe supercapacitors) to smooth out the available power to the electric motor. Without batteries, the mileage would drop.

    They could sell a version with fewer batteries, but it would still be more expensive than a hybrid with comparable mileage. Better for them to charge a premium and fill the 'plug-in ERV electric' niche instead.

    A discussion of weight doesn't change the fact that the original poster is incorrect about his assumption that performance is automatically going to be the same on an electrically-powered vehicle when running on battery, accelerating on stored charge in a capacitor bank or running directly off its generator. The amount of power available to drive the motor is different in all those scenarios, so the only way you will get identical performance is if you artificially limit all of them to the performance characteristics of the lowest performing mode of operation.

    Automatically the same, no, but it's relatively simple to engineer it that way. Consider that an engine's hp is measured as the peak. Under normal driving conditions, the engine puts out far below its peak power, particularly if your car has an automatic transmission. You only need that peak power for 10-15 seconds as you accelerate to highway speeds. Moreover, the electric motor will only use its peak power at high revs, meaning high speeds.

    Let me rework your numbers. I'm guessing normal driving conditions will be closer to 33hp, or 25kW. Your estimate of nearly 20% losses in the power system seems high to me as well (I'm an EE), let's go with a more reasonable 10%. So, a 30kW (40hp) generator would be able to charge the battery slowly.

    So there may be a limit to the performance (can't keep the pedal to the floor at 100mph when the generator is running for more than 1 minute), but it's unreasonable for anyone to reach that limit under normal use. This won't be a race car, but you can't fault it for that, just like you don't fault a Larmbourghini for not being able to tow a trailor.

    2) The idea is to not play whack-a-mole and have to ban a cheater 5 times, once for each game. It results in a better experience for the clean end-user.

    cheating in one games doesn't mean cheating in an other game.

    Not necessarily, but if there is a serial-cheater on PS3, Sony really can't do anything about it. Even if it's only one game they get banned from, they could make another PSN account for free and continue cheating.

    Yet MS did that + other things to render the console it self useless (and that wasn't for in game cheaters, it was done to people who moded their box, some do it to play backups -- not paying for games --, some simply do it to get more out of their console, but that doesn't make a difference they are banned).

    Right, but the consoles broke the ToS and were thus no longer elligible to use any Live-enabled services. Microsoft is under no requirement to provide online service to them, and the players can still access Live from un-modded consoles.

    PC is a gaming platform with less control, an yet it is very successful (it is related come to think of it).

    I wouldn't say that PC is more successful, aside from Valve, Blizzard, and The Sims being the obvious success stories.

    Of course, if you want to continue that train of thought, the Wii is equally restrictive (can't even use text chat aside from pre-entered sentences in most games) yet has much larger sales. So, the secret to success is no unifying online presence (different ID for each game) and limited communication?

    As for ToS most people won't bother reading them and most of those people take them lightly or see them as just an annoying step to get what they want. (that is a very big problem in it's self, EFF web site has some nice reading in that regard)

    I agree, but I don't think that gives carte blanche to break them, especially if the terms are obvious. I can have sympathy on some people, but when it comes to cheating you should know you're doing something wrong and could be punished.

    1) Banning them from the service is fair if you don't follow the rules of the service. MS doesn't just ban on a whim.
    2) The idea is to not play whack-a-mole and have to ban a cheater 5 times, once for each game. It results in a better experience for the clean end-user.
    3) Many cheaters in a game are simply banned from that game by the developers, depending on the nature of the cheat/exploit. Microsoft only bans accounts when there is a ToS violation.

    They can ban the PS3 it self.

    Seems like a much more severe penalty than needed, especially if multiple players share a console. And, it would result in increased used consoles which have no online capabilities. Ban the player, not the terminal.

    On an other unrelated note, forcing people to pay to play online is just plain wrong (not talking about World of warcraft, the games is designed that way). most shooters on PC you get at least the possibility to set up you own game server and invite friends without going through any service at all. a possibility that is taken away in the console world. and With PSN they're are adding premium to get more money but for added values you can opt-out from, at least the basic feature (among other things) of playing will remain free.

    Right, PC games (usually) do it differently. That's not the issue here. We're comparing PS3 to XBox online service.

    Regardless, MS charges for the online services they provide, one of which is maintaining a level playing field by globally banning cheaters. Many feel this is worth paying for, others don't. Use whichever you prefer.

    No, control on their network. MS only has control over their hardware in as much as they can limit access to their network capabilities. However, more importantly, they can use this same control to limit any ToS violation, particularly cheating, while any mechanism on PSN can be easily circumvented with a new account.

    would you care to elaborate on PSN vs Live ??? Live has nothing more to give than PSN except the cost (I don't see the added value to justify that) Frankly I fail to see a relation between the matter at hand and that.

    On Live, if you get banned for violating their ToS (for example, hacking your box, cheating, sufficient complaints of racism) then you are banned from all online play. On the PS3, Sony does not (to my knowledge) participate in the ban process except for their own services. So, if you get banned from Home for racism you can still play all your other games online. Each game needs to ban you individually, thus fewer asshats will be banned for any particular game.

    Even the cost itself helps here. If someone gets banned from PSN for cheating, they can just make another free account. If someone gets banned from XBL, they must pony up cash to create a new account, giving a monetary disincentive not to cheat.

P.S. Good courses dealing with vector calculus targeted at programmers will deal with tractability, precision, performance, data storage and other issues, and will learn you many a great lesson on doing for example matrix math efficiently, including the most important one: there are good matrix maths libraries out there, use them - people have devoted large chunks of time to small parts of them and you can't hope to outdo them. Avoid doing such low-level things yourself unless you genuinely have special needs.

    First, the problems solved by calculus don't make you a good programmer without the fundamentals of discrete to back them up. If you can only write specialized functions, you will be quickly replaced by someone more versitile than you (especially if you are self-described 'bad at math').
