  1. practical applications on Controlling Robots with the Mind · · Score: 0
    Our immediate goal is to help a person who has been paralyzed by a neurological disorder or spinal cord injury, but whose motor cortex is spared, to operate a wheelchair or a robotic limb.

    wheel chairs? fsck THAT... I want to control a Gundam, dammit.

    I mean -- that is probabbly the *only* reason to design a big robot in the shape of a human -- so humans can control it with roughly the same movements and feedbacks.

    small side note: that is one UGLY monkey. I mean... can't they find a cuter monkey for experiments like this?

  2. rocket engines and heat on More on JSF Laser System · · Score: 2

    conversely, If you look closely at rocket nozzles, you will see rings abound. these rings carry liquid O2 / H2 and heat them up (via the exhaust) before the enter the combustion chamber.

    (back ot the subject)

    as far as the laser is concerned, automobiles routinely rid themselves of that much heat via conventional radiators. I do not see this as a *big* problem, especially considering the atmosphere is about -40 where the aircraft operates. (granted, at a high mach the aircraft heats up due to drag -- in fact SR11 _extends_ 11 inches due to this heat!) -- to back up my claims: a gasoline engine is usually ~20% efficient. with a shaft output of 300HP (your regular sports car) your radiator / exhaust gets rid of ~ 1200HP of heat, which translates to just around 900kw.

  4. Re:Random Comments on Biology and Slashdot on Ready, Steady, Evolve · · Score: 2
    Which brings me to understanding the cosmos - it's easy to prove that we aren't capable of understanding it in any complete sense. However, given time and access to sufficient information, we are capable of developing theories which encapsulate and communicate the essence of what's going on. It's difficult to imagine any rational, detectable process, which does not involve a deity, being impenetrable to the application of analysis and logic, and to the development of appropriate theories.

    you touch on an area of Epistemology, which says (summarizing you) "through abstration, will I (or, sentient beings in general) have infinite knowledge?"

    the long answer will not be iterated here; there are TONS of papers and books written on this... but the short answer is: they havn't decided yet. ;^)

    so... point being -- don't bank on the fact that we are able to (within these 3-lb bundles of fat) develop theories that encapsulate the entire cosmos, through abstration or otherwise.

  6. 137 comments later noone think this may be a hoax? on Dell Partners with Square · · Score: 3, Interesting
    i mean... seriously... are there ANY other sources backing this up?

    Square USA has nothing even close to this; Dell is silent as hell. even square japan has nothing at all:

    the only press release i can find is here but it just says Nvidia chips are used for testing and with the "best way to play" logo -- so does Unreal Tournament 2003 -- it says nothing about GeForce being the ONLY playing video-card (as all directX compatible (OpenGL?) should work okay. (just like UT2k3 runs just fine on my radeon)

    besides this is all for japan anyway. There are rumors (Electronic Gaming Monthly) that says there may not ever be a FFXI release because of the massive amount of support square will have to burden -- and if EA does not want to do it, they may just skip it. (can't find online version of article)

    small side note: i remember back in the days when FF7 supported every videocard *except* nvidia TNT... haha... but eventually nvidia gained enough popularity / people bitched about it and they released a patch to allow nvidia. (they even had software rendering back then!) i bet if us radeon users bitch enough they will make a patch for it too.

    another small side note: again. back in FF7 pre-nvidia-patch days -- the software rendering was so slow it was possible to predict the slot-machine thingy for one of the mini-games. i actually did much worse in that mini-game after the patch was installed. -- so i finished that part with software rendering, and played the rest with the patch.

  7. Re:I want a recompiled FF7 on Dell Partners with Square · · Score: 0, Offtopic
    I want to be able to play FF7 on my new PC.

    yeah and for fsck's sake re-do the game so you can bring Aeris back to life for the ending, man... I swear there is this entire generation of gamers who are scarred because of it.

    granted, some would say that it was that part that made it one of the most memorable games ever, but still! huge emotional (?) scar vs. memorable game... i'd choose over happy memory anyday, kay?

  8. Re:Mac Laptops on Flirting With Mac OS X · · Score: 1
    I like Dell's approach on the Inspiron I have - put both on the machine, let the user decide.

    I like pretty much everything about my inspiron except that. the track point digs into the screen and scratches it up. 15" 16x12 screen, that i have paid dearly for, scratched up because of an annoying purple (PURPLE!) fuzzy nipple that I *never* uses.

    And -- the damn thing will fight with the pad for control sometimes, rendering the pad not-useable either until it finishes the drift adjustment.

    sigh... why have people stopped shipping laptops with small trackballs?

  12. If this is not "anti-competitive", then what is? on Microsoft Buys Rare · · Score: 2, Troll

    Here goes microsoft with their dirty tactics again... sigh.

    not saying that SONY would not, if they had the money to do it -- oh wait, they DO have the money to buy a couple outside developers just for shits and giggles, but didn't.

    Same story has happened before, guys... I remember back in the days when M$ literally parked a "hiring booth" in front of Borland and basically said "if you sign up right now, we give you 150% of what you are making and then a huge bonus (6 figures, maybe more)." look what happened to Borland.

    As much as the Xbox is a better system (technology-wise) I would not buy it on principle. doing so is to encourage more of the bloodshed in the world caused by M$ that's already way-too-much. to paraphrase it -- Microsoft is the sickle that harvest the souls of computing.

    Anyone who don't think you are suffering because of this game developer buy-out thing: remember: Halo was supposed to be released for PC first. and now Halo 2 is about to come out... where is the PC version?

    right but you will move data in 64-bit chunks. so even if you have less than 4Gbits -- if you properly write / optimize your code you can get double throuput from a 64-bit CPU (okay not double, but a significant increase)
