  1. I know what I'd prefer on Hands-On Review of PocketPC · · Score: 3

    This is the inevitable car analogy, but I think that there's
    a similarity to car buyers that needs to be said.

    Given $40k to spend on a car there is one sort of person who
    will buy the sports car with a huge engine and sunroof. The
    Imprezza or an M2 attracts this sort of person like a fly to
    honey. They want the horsepower, the bucket seats, the mags
    and sports tyres, etc.

    Then there's another sort of person who thinks the Imprezza
    or M2 is impractical. You can't seat four people in comfort,
    the bucket seats are small and restrictive, the big engine
    is a waste of petrol for city driving, and the boot is just
    too small. These people prefer a nice roomy sedan.

    My opinion on this is that some people want a car they can
    show off to their friends. They want to tell everyone how
    big the engine is, how fast it goes, how much it cost. The
    sedan owner just wants a car they can use every day, that
    is practical and useful, and is good value for money.

    My Palm Pilot 3 is practical and useful. I also think I'd
    in all honesty prefer a sedan to a sports car.

    Please read the entire thread. I don't agree with the previous person's argument, which is why I began with the devil's advocate position "if this were true...". Not A -> Not B, B, therefore A.

    It was non-sensical of the previous person to say that Sony had sued Bleem because Bleem prevents Sony from losing money on each console sale. Sony would have to be stupid to do that.

    It's clear that Sony sued Bleem for other reasons than the one the previous person suggested. I'm not willing to delve into pet theories though: it is pure conjecture on the theorists part.

    They sell the box for a loss but make it up on the $21/mo service fee. This is exactly the same business model the video game manufacturers use. The super-advanced 3D graphics chips in the PlayStation are cost way more than the selling price, but Sony makes it up in license fees for the games. Hence why Sony is attacking Bleem so ferociously, and the same reason Netpliance is beating on their corresponding "open hardware" hackers: it destroys their business model.

    If this were true then Sony would actually be encouraging sales of Bleem because it means there is another person out there with reason to buy the overpriced games and Sony wouldn't have to sell a loss leader console in the first place.

    Bleem is effectively a free console for Sony, no loss, and still many money-making license fees from all the games the Bleem user purchases.

    uhhhmmm.... no think about it, why would the spacecraft be rotating, the people inside rotating with the craft, but the M&Ms not be rotating

    Because that explains the scene. That is the point of the exercise isn't it.

    when there is a fly buzzing around in your car and you take a corner hard, does the fly smack into one of the windows?

    If you corner hard enough, yes. Think about the situation where you slam the brakes really hard. If you're not wearing a seat belt then you fly through the windshield. If you corner hard then you feel yourself being pressed against the side of the car facing away from the turning corner. A fly does smack against the windshield if you slam the brakes hard (try it, it's fun).

    nope, he just keeps flying right around in the middle of your car.

    That's because the fly has the ability to fly away from the window which is coming towards it. An M&M doesn't have the muscle power.

    the objects inside the space craft share the inertia with the spacecraft

    I believe you're thinking of "momentum" and not "inertia".

    My devil's advocate theory is that the spacecraft is rotating. The spacecraft causes the occupants to rotate also either by butt friction on seats or by applied force through seatbelts. The M&Ms would only be "attached" to the spacecraft via frictional forces with the air in the craft. This tiny force would certainly allow them to remain stationary while the craft rotates, giving the illusion of rotating M&Ms to all occupants of the craft.

    It can't match anything much on 'user apparent' speed grounds -- X's event model takes care of that.

    This often quoted "fact" is never ever backed up by evidence or experiment. The simple fact is that people who do profile such things (including people from XFree86) find that X isn't a problem as far as speed is concerned.

    And I have no idea where your claim that the X event model (of all things) should be the major factor in the "speed grounds".

    It isn't extensible, regardless of what everyone else says -- for examle GLX was around donkeys' years ago, but no-one's able to 'extend' XF86 with it until now (you can't extend X at run time, you've gotta hope you've got the source to extend it at compile time, and then you've gotta make it work with your X server)

    Far from proving your point, you instead do a fine job of disproving it. X is highly extensible, thus the vast number of extensions in even the most normal X installations (Shape, MITSHM, DGA, DPS, GLX, vidmode, XInput).

    Its , network transparency was done better by QNX with their MicroGUI (which based its protocol around distributed IPC). Even NeXT could just redirect object commands and postscript display commands -- X didn't have the display model to keep up.

    As a person who had the displeasure to use a NeXt cUbE, I must say that you're speaking crap. NeXT died because it was so goddamn slow compared to X: this should be proof enough that X was the superior design of the two.

    QNX's MicroGUI I cannot comment on, but if it is anything like QNX then I'm not going to be at all impressed. QNX is like SYS7 only without all the usability (SYS7 users will note the sarcasm).

  13. Re:Wine with Starcraft still crashes on Forum: Future Ports of Games to Linux · · Score: 1
    Off topic: Does anyone know why DGA is so much faster than MIT-SHM, and why it needs root?

    Normal X operations go over a pipe (usually a fifo or socket). There is one copy from the client into the pipe, one copy out of the pipe into the server, and then the X server decodes the request and does the operation. Note that though this may sound inefficient, in practise you have to do similar copies in any windowing system (ie systems using message passing).

    MIT-SHM uses a shared memory (shm) pixmap between the client and the server. The client draws into this pixmap and then XPutImage(3) copies the pixmap onto the screen. This avoids the X pipe and thus saves several copies of the (often large) pixmap data. This is as efficient as you're going to get without some additional knowledge of how the framebuffer memory is laid out.

    DGA uses mmap() to map the framebuffer VRAM into your client's memory space. This naturally only works on some cards, and mmap() is a root privileged operation. The client then draws the data directly into the framebuffer. This means it avoids 1 copy over MIT-SHM and avoids X pipe encoding/decoding code. This is as efficient as it gets (without hardware assistance).

    There is the possibility of making DGA not require root privileges by using Capability Flags but nobody has actually written any code yet. Note that X isn't any worse than MacOS or Windows in how it handles these things. X may appear to be inefficient but in fact it has similar performance and API complexity to the more media-oriented windowing systems.

    I don't like running Starcraft as root, but it doesn't run as smoothly otherwise. For DGA, couldn't the X server create a file mmaped with the necessary I/O range on the graphics card, then set permissions on it to let the X client mmap that same file to write directly into that chunk of RAM without security concerns?

    Write the code. If you get it to work then I think the XFree86 team would happily accept your submission. I think you'll find it is not quite as simple as you outline here, though.

  14. Not that bad... on Preliminary Injunction Issued in DVD CCA Case · · Score: 4

    OK, it's not 100% positive, the injunction did go through afterall.

    Fortunately it does seem the judge isn't a clueless gumby. He makes point on the sixth page that a website's owner isn't responsible for information on sites that you've just linked to. This shows an understanding of the Internet's workings and delineation of responsibility.

    He also explicitly permits continued analysis and discussion of the CSS algorithm, even under the injunction, as long as the algorithm and keys aren't distributed. This is mildly positive, as it may mean the other CSS defeater (the 18 second brute force technique) would be legal.

    He refutes the claim that the encryption was unusually weak, citing the three year period when it wasn't cracked as being proof. Fortunately it should be easy to bolster the "weakness" claim by getting some expert witnesses in cryptography. I have heard there are only 2^16 unique tests!

    He agrees that reverse engineering is "proper means", but only if the DeCSS author didn't agree to the click license. He says that the DVDCCA's argument here is "problematic" as they (1) cannot prove Johansen wrote the code or (2) that he'd agreed to a shrinkwrap license.

    Finally he strongly emphasises that the real reason that he's granting the injunction is because the harm to DVDCCA by not granting the injunction is far greater than the harm to everyday users by granting the injunction. This strikes me as being fair enough.

    My overall impression is that the judge does understand the issues here and that the judge is intelligent and thoughtful. Also the decision to grant the injunction is the fairest decision that could be made: it minimises harm to all parties given that the judge doesn't know what the truth of the matter is.

    I would think the 6 page statement also says quite clearly to the EFF how they should proceed. The EFF needs to prove that 40-bit encyption is weak, that the reverse engineering was undertaken for "proper means", and that Johansen could not have been held under the "click license". If the EFF can prove these points then they answer all of the open-ended questions in the judges report.
