  1. Re:Kind of shady? on Meet the Hackers Who Get Rich Selling Spies Zero-Day Exploits · · Score: 0

    There are also laws against doing things like shooting an unarmed person in the head, aka assassination, but if a soldier hears his superior yell "fire", he shoots, no questions asked. In theory, the govt. abides by its own laws, in practice, 'national security' trumps all laws, and even the courts have agreed, allowing the govt. to withhold evidence on the basis of national security. Govt: "He's guilty!" Judge: "why?" Govt: "We'd like to tell you why, but that harms national security." Judge: "oh, okay, he's guilty."

  2. Re:What's a smartphone anyway? on Nearly Half of American Adults Are Smartphone Owners · · Score: 1

    Smartphone = WiFi. If your phone can do WiFi, all the big service providers, Verizon, Sprint, ATT, etc. require you to get a "data plan" because they're shit scared you'll be happy with just WiFi and never subscribe for a data plan. It doesn't matter if your phone can crack 128-bit encryption in a minute or has a pico-projector to play 1080p 3D on 80" screens, an integrated deep blue and that IBM bot that won jeopardy, if it lacks WiFi, you'll be able to avoid paying for the data plan with service providers who'll deem it a dumb phone / feature phone and not a smart phone.

  3. Re:Well, there goes *that* heroin shipment on Senator Rand Paul Detained By the TSA · · Score: 4, Insightful

    That's always been my view as well. The best post-9/11 security measure has been psychological. Every passenger is psychologically trained to refuse to believe they will land safely if they 'cooperate' with hijackers. That was the only real weapon a hijacker had, not boxcutters, not a gun, but the illusory promise that all will be fine if everyone just cooperates. That weapon, the psychological stranglehold, has been screened out, and that "solves" the problem of 9/11 ever repeating again. Case in point, flight 93. It never flew into a building. All it took was some passengers to have learned that the hijackers will not release them safely.

  4. Re:Actually Islam is pro astronomy on The Dangers Of Amateur Astronomy In Afghanistan · · Score: 1

    The Taliban are based more circa-1700s, whereas the "golden age" for the Middle East was closer to 700-1200 AD (http://en.wikipedia.org/wiki/Islamic_Golden_Age) Whenever a group looks backward and tries to be old-fashioned, they never pick a particularly advanced, progressive period. None of the right-wing "return America to how it used to be" folks want the 1960s with hippies, civil rights, and space exploration, even though 1960 is definitely old-fashioned as it was a half-century ago. They rather have the 1980s wall street 'greed is good' or the 1940s 'white man in charge' eras. In essence, the folks who look back always pick a very rigid, uncreative era. The creative don't look back, they just create and build anew.

  7. Re:Speed vs Bandwidth on Virgin Media Demos World's Fastest Internet Service In the UK · · Score: 1

    You're forgetting switching latency. A single high-end switch adds 600ns latency, and a single low-end switch adds 200us latency. If you have 20 hops, that's 12us vs. 4ms. And crappy wifi-routers can add 20ms of latency each. So, no, their average speed is not k*c where k is slightly less than one. One crappy wifi-router's latency is equal to light traveling 4,000 miles (more than the distance from NYC to London).

    Hey you, my foot is 12 inches long, and I measured my front yard, and it's 3 feet to the curb.

  10. Re:Not that surprising, actually on 5 Out of 11 Crashed Unity In Canonical's Study · · Score: 4, Informative

    Um, people do kernel programming in virtual machines. And there's plenty of debugging tools around VMs. I know, I write kernel modules.

    Also, kernels can mask interrupts and ensure a function is run "single threaded" (no context-switching out), which dramatically reduces the complexity. Not every function is set up like that, many are thread-safe, but drivers are usually written to be uninterrupted and access private memory, so they don't worry about interaction with other cpus/cores/kthreads.

    Both are hard, kernel programming is hard, and the massive multi-threading in window managers is hard.

    It's still far better than Google and other search tools currently available. Type a jeopardy question into Google, and click "feeling lucky" -- you won't find squat.

  22. Re:I'll be first to say WTF on Polynomial Time Code For 3-SAT Released, P==NP · · Score: 1

    Exactly - it's a very common epsilon-delta proof. You challenge the opponent to find an epsilon they think your answer is wrong by, and you come up with a delta that beats your opponent's epsilon. In formal terms, (f(x) - f(x+delta)) epsilon. In this case, f(x), the target is 1, and delta is -epsilon. If your opponent challenges you to find a number 0.0001 close to 1, you can give him 1-0.0001 (aka 0.9999). Because your opponent can pick arbitrarily close to 0, and you always have a delta to win the challenge, then your opponent cannot claim your number is any different from 1.
