  1. Re:Pedestrian problem on GTA3 and Vice City now Online Multiplayer · · Score: 1

    If every copy of GTA in the game received events from the outside world at the same time, then that approach (sharing a random seed) would work. Unfortunately it ain't quite that simple.

    Initially, everyone's game will be perfectly in sync. But when Johnny squishes Alice with his car, Johnny's game knows about it before Alice's, because the message needs time to propagate across the network. So Johnny's game makes his pedestrians react a split second before Alice's pedestrians react, and those in turn react a split second before Fred's peds react, and so forth.

    Repeat 100,000 times, and peoples' games quickly become desynchronized.

Not electronic, mind you -- which would imply the use of a transistor somewhere.

    I'm not doubting that they've got infrared LEDs in the toy, or that they use them for simple obstacle detection -- but to call it "radar" is rather grand and misleading, don't you think? For one, "radar" connotes the use of the radio portion of the RF spectrum -- or more often these days, the microwave. When you perform rangefinding with light, then it's called "lidar."

    Of course, lidar is quite uncommon, and certainly beyond the capabilities of a $200 children's toy. I doubt very much that the RoboSapien does any sort of rangefinding at all. Either it detects an obstacle within a fixed radius of its sensor, or it detects no obstacle. Hyperbole and pedantry aside, that's my real beef with their use of the word "radar."

    This might work most of the time... but when you're writing the advertising copy for a toy marketed toward geeks? Really, now!

    Next, they'll be claiming that Robo Sapien is capable of a running crawl. He'll be compatible with wired WiFi! He'll be able to jump to great depths, leaping tall buildings in a single dive!

    Then again, maybe Robo Sapien really CAN emit both infrared and radar. Perhaps in 2006 he'll come in x-ray and microwave flavors, followed in 2008 by the gamma ray Robo Sapien.

    Surely, you can't be serious in suggesting we fund yet another Wonder of the World. While another Manhattan Product or an Apollo Mission would bring us valuable influence and perhaps lead Canadian and Mexican border cities to rebel and join our nation, there is little chance that we would complete either project.

    Our scout units have reported that the Chinese and the Indians are both working on these Wonders, devoting the output of their largest cities. You and I both know that our industrial output, measured in shields, cannot compete with theirs.

    The long-term path to victory is clear, my friends. We must build Improvements on a city-by-city basis in order to solve the energy problem. Most of our cities have a Granary and an Aqueduct now, which is a good first step. I recommend a Factory to boost production, followed by a Recycling Center and a Power Plant in each city. This will both reduce pollution and increase industrial output, allowing us to build ever more military units and product ourselves from ever-more-frequent Barbarian uprisings.

    Once we have adequately defended ourselves, we can turn our industrial output toward the most important goal: building Modules for the starship that will someday take our descendants to Alpha Centauri and allow us to win The Game. Scuttlebutt has it that our scientists have almost completed the research necessary to build a Propulsion Module for our starship!

  11. Re:ridiculous on Electronic Arts Facing Possible Class Action Lawsuit · · Score: 2, Interesting

    I've been writing software for fifteen years, and games for ten. I've worked on a major 3D game title (albeit not in the critical path to development) and have voluntarily stayed at my desk for 12-18 hours a day, seven days a week, for 2-3 months at a stretch. I am no stranger to hard work.

    But my game development time was spent in a small team, three coders and two artists, funded out of our own pockets and creating our own 3D engine from scratch.

    Game programming is not special. It's not fundamentally different from any other area of software design. Do you intend to claim that 80-hour work weeks are the norm in the game programming industry? I have half a dozen friends working at variously-sized game development houses in the bay area who will dispute that claim.

    If EA is so mismanaged, and their employees so underproductive, that they are throwing their teams into 85-hour-work-week crunch mode for upwards of HALF the project's development time, then there is something very, very wrong at EA. They need to come up with more realistic schedules for their projects, or find more productive coders, or find managers who have a clue about software design, or learn to reuse code, or SOMETHING.

    OTOH, it sounds to me like EA is WELL managed. They've cottoned to the idea that more productive teams means smaller teams and a shorter development cycle. By setting aggressive schedules, they're insisting on a level of productivity from their employees that is unattainable to the employee of average skill and intelligence. So they ramp the hours up, ever more, in order to fit the overly-aggressive schedule they've devised.

    Now, if there is no incentive against EA -- or any company -- employing such a practice, why don't all of our employers go that route? How would you like to live in a world where every job keeps you at the desk from 8am to 10pm, seven days a week? If all employers have been obliged to adopt the same grueling labor practices in order to compete, then you no longer CAN leave your job -- any other job you find, will be just as bad.

    The problem with letting the market do what it will is this: optimal efficiency is achieved through destructive means. The greatest profit can be had by he who is able to create the most externalities and therefore seat others with the cost of his operations, while taking the gains for himself. This is true in the mining industry, it's true in the petroleum industry, and it's true in the software industry. If you don't impose SOME regulation, then a rational entity will always choose to maximize its own gain regardless of others' losses.

    The goal of labor legislation should be the same as the goal of environmental legislation: to close the loop, to provide a feedback path that curbs the number and magnitude of the externalities that businesses can create, and holds them accountable for the negative consequences of their actions in situations where they are not already fiscally responsible for those consequences.

  12. Re:Smart guns are not a smart idea on Hardware That Recognizes You · · Score: 1

    All good points. When the technology matures to the point where its failure rate is virtually nil, *then* we can begin addressing the use cases for a weapon that authenticates its user.

    From what you've said (and I'm too lazy to go ask my cop friend, so I'll trust you), most shots fired are snap shots. In that case, we'd need to optimize the smart gun system so it worked flawlessly under those conditions. I agree that the weapon's "intelligence" is secondary to a cop's -- but it never hurts to add a fail-safe to your system, whatever it be.

    Perhaps the weapon will allow one round to be fired before it's authenticated the user. Perhaps it stays enabled as long as it's in the holster, and allows for a 1-2 second grace period after being removed before ceasing to operate if it hasn't re-authenticated. I don't know the answer -- and I agree the technology isn't ready yet -- but that shouldn't stop us from researching it.

    In scenario #2, what would happen if the gun weren't smart? Correct! The officer would still be killed, if he were foolish enough to let a bad guy get control of his weapon.

    In scenario #3, what would happened if the gun weren't smart? Bad Guy would disarm Cop, and instead of taking Cop hostage on account of the useless gun, he'd just shoot Cop in the head. (If the gun were smart, OTOH, Cop could use any number of rasslin' techniques to disable Bad Guy without necessarily moving his hand near Bad Guy's gun.)

    So you see, in most scenarios, the cop's, bad guy's, and innocent bystanders' chances for survival actually *improve* when the gun is smart.

    Let's not forget that cops aren't trained to act like cowboys, which is to say they don't draw and shoot. When a cop fires his weapon, he's usually been aiming his gun for some seconds or minutes in the classic two-hand stance (which, btw, provides some natural redunancy for the gun's recognition device, if both his hands are chipped).

    Imagine a system that authenticates the weapon by recognizing the offier's chip, and then *stays* authenticated as long as there is pressure on the grip. Even if the system glitches and recognition fails, the cop can still fire at will. (What's with this misplaced anger toward Will?)

    There's a future in law enforcement for well-designed and well-tested smart weapons. But there's an even bigger future for nonlethal wepaons.

Oftentimes, such criticism is levied against VMS sufferers even when the application in question is I/O-bound and spends 80% or more of its time suspended, waiting for network or disk I/O to complete.

    TREATMENT: Implement reliable and efficient systems using virtual machine of choice, regardless of criticisms. Apply free-market therapy judiciously, allowing adopters of Virtual Machine technology to thrive and become prosperous if warranted.
