Comment: These stories suck they need to fit the format.... (Score 1) 34 34

Machine Learning System can detect X with such high accuracy and with so few false positives as to be actually useful.

Frankly detecting X is basically defined as getting better than random chance. If you decide that anybody who posts "I am so sad" is suicidal, you'll bound to get a few hits, so there. I developed an algorithm that can detect suicide and depression. The problem here is that it's useless unless it's really really accurate.

1. Your airbag didn't cost $150,000,000.
2. We're not talking about something that will only be used once per flight. We're talking about something that will only ever be used once, because no similar stage will ever fly again. If you must have a car analogy, it's like designing a new car which you'll only make one of, and you'll set it on fire at the end of the first drive.

For one thing, airliners don't carry IFF. For another, IFF is not infallible; if I remember correctly, the Tornado(s) the US ground missile batteries shot down in the Gulf had IFF, but it wasn't configured the way the US crews expected, so they decided it was an Iraqi plane even though they hadn't been flying for days.

Not being allowed to shoot at the range the aircraft was designed to engage at because they can't positively ID the bad guy is a common complaint in the pilot memoirs I've read from recent wars.

WTF?! When was the last time you've ever heard of a dogfight?

That's what they said when they built the Phantom with no cannon. That's why they had to hurriedly retrofit cannon for Vietnam, when Phantoms started getting into dogfights.

As for long-range missiles, they've been the panacea for decades, but then the military impose rules of engagement requiring positive ID of the bad guy before you shoot, and suddenly you're not at long range any more.

It's not crap. The Athlons crushed the Pentium 4's. I remember that very clearly. Slashdot people should know this unless you were born yesterday.

1. Comparably priced 32-bit Athlons only beat the P4 on floating-point-intensive tasks that didn't use SSE. Which typically meant games, but not pro-level 3D applications like the ones I was running.
2. The performance difference was nothing to do with the FSB.

Yes. Back when I had the misfortune to work on Windows, I was one of the people in the company who were continually running benchmarks, so I was one of the few people in the company allowed to not have anti-virus software on my PC, because it turned the computer from one of the fastest then available to a complete slug that spent most of the time hammering its hard drive.

Most public domain software is free, at least at first glance.
