    Wait, have you actually tried this?

    One of the things I noticed about the Win7 RTM was two Win7 computers see each other's shares, and changes thereto, almost instantly. Way way faster than when I was trying to get Vista to see the shares on the Win7 beta.

    And no, I'm not using homegroups or whatever they are.

    It actually does have something about the time interval during which the force of the explosion is applied, but not really in the way you think.

    Force F.
    Mass m.
    Acceleration a.

    F = m * a.

    During the explosion, force is exerted on the gun in one direction and the bullet in the other.

    I don't know what shotguns are popular with gangbangers nowadays. Say the mass of the shotgun is 5kg and the mass of the slug is 10g.

    Mass m1 = 5kg
    Mass m2 = 0.01kg

    Say the force applied to the bullet by the explosion is 100N (I don't even know if I'm in the right ballpark, but hey). Then

    F1 = F2 = 100N.
    a1 = 100 / 5 = 20m/s^2
    That's about 2 Gs. Not that much.

    a2 = 100 / 0.01 = 10000 m/s^2
    That's about 1000 Gs. A lot.

    So as you can see, the bullet sees a lot more acceleration out of the same force.

    Now this is where it gets complicated.

    1) Read up on Impulse.
    2) You have to realize force is not always applied instantaneously - it's applied over time, in a graph like this one: http://www.antonine-education.co.uk/New_items/TRA/Stopping_files/image001.gif
    The area under the graph is impulse.

    3) Since the acceleration on the shooter side is much lower, the shooter can handle the recoil better and spread the impulse over a wide time, which means on the impulse graph the time interval is long. On the other hand, the bulletâ(TM)s deceleration is almost instant, so the impulse is concentrated in a very short time interval. That means during this time interval, the maximum force is much higher than the maximum force at any point on the shooterâ(TM)s impulse graph.

    For a simple illustration, look to the sample impact graph above. Think of the orange bar as the impulse applied to the target, and the yellow bar as the impulse applied to the shooter. The total impulse is equal so momentum is conserved, but the maximum force experienced is different.

    There are other factors involved, one of which is obviously pressure - the force on the shooter's side is spread over a higher surface area, whereas the force on the shootee's side is concentrated in a small area.

    The point is, the force is applied over a shorter amount of time over a smaller area to the target of the shooting, which means the maximum force experienced by the shootee is higher than the maximum force experienced by the shooter.

    You're probably thinking of the related movie factoid where a bullet makes a guy go flying for ten feet, which is the impossible one.

    Momentum is conserved but doesn't break the shooter's arm because the shotgun is much heavier than the payload.

    So wouldn't it be Opera's fault that it doesn't have Internet in its name? Why are "the clueless" responsible for being informed about obscure browsers when they don't really care? If the problem is really prevalent as you say, and Opera really wants to capture this totally-clueless-picks-browsers-based-on-the-name market, then isn't it Opera's job to change its name to say, Opera Internet Browser(c) or some such? After all, it's not the consumer's job to be informed about products and choices, it's the marketing department's job to inform their target market about their product.

    Developers should take a lesson from this. I still cringe a little every time I open the GIMP.

  16. Gloating? Really? on Opera CTO Thinks IE Will Be Forced To Support SVG · · Score: 3, Informative

    That's funny, because I actually had to deploy some SVG-based webapp last week. Specifically, it was outputting scatter plots with some few thousand data points. I tested SVG performance in Opera, Safari, Chrome Firefox 3.5, Internet Explorer with Adobe SVG Viewer 3.03, 6 (alpha? pre-alpha? No one knows...), and the RENESIS plugin for IE.

    Here are the results:

    Opera - Easily the slowest of the bunch. Took about 15 seconds to render the graph.
    Safari - Got confused about the app's filetype and kept trying to save it.
    Chrome - Pretty fast, took about 2 seconds to render the graph but strangely starts rendering the datapoints in small chunks after (it'd draw the first half of one series, the the next half, then the next series, etc).
    Firefox - Not much faster than Opera.
    Adobe SVG 3.03 - About as fast as Chrome but was missing some features, like changing the cursor display when you hover over interactivity points.
    Adobe SVG 6 - The snappiest of the lot, and supports the cursor changing feature, but likes to draw erroneous datapoints. Too bad Adobe dropped development on this.
    RENESIS - A little faster than Chrome but not as fast as SVG Viewer 6. No errors and wasn't missing any features as far as I could tell. This is what I ended up going with.

    So, why is Opera "gloating" over IE when they themselves has a LOT of work to do on their own SVG support, to say the least, while there are free plugins for IE that pretty much trounce the competition? Does IE really need built-in SVG support when this is the case? Maybe it needs built-in flash support too?

    To me, this just looks like another case of unwarranted smugness over "omg IE doesn't conform to standards!!1".

    Ritual suicide isn't a way out of a difficult situation, or giving up in the face of a challenge.

    I think your mistake is the impression that external observers despise failure and pressure someone into suicide. That is not the case. It's acknowledgement that there is nothing you could do to make up for your failure. It's a voluntary offering of your own life as the most sincere apology possible and the ultimate show of respect for those you've wronged.
