Alas, Python lambdas are very limited, only allowing a single expression. If you need a function that does two things, you can't use lambda anymore. This is not a great hardship as Python allows you to declare inner-scoped functions and you can use that instead, but it's still annoying. I do recommend Python though, as it's a great language even with the occasional shortcoming.
The design's fundamentally flawed, the rocket's so slender it "wants" to fly backwards... the control system has to fight its natural flight mechanics the entire way up to keep it straight.
Such active stability systems are old hat. The F-16 does it on purpose, for example. This sounds more like irrational hatred than a sound engineering evaluation.
Frederick sounds scary. I've talked to some of the guys who fly gliders there and some of their stories will turn your hair white! Corporate jets blasting through gaggles of gliders at 5,000ft....
If you should happen to find out anything about the MITRE unit before Slashdot closes comments on this story, I'd very much appreciate hearing what you were able to discover.
Ah sarcasm, the last refuge of the complete fucking moron.
You think I'm wrong, find me two billion people who don't have enough to eat. I want names of countries and numbers of people, not just vague handwaving. Or get lost and crawl back under your hole, I don't really care which.
That's probably true enough. However the cost of a cutting-edge procedure in 1950 will be dirt-cheap today, assuming it's still available and hasn't been completely superseded by something better. That's really my main point, that a pricy immortality treatment invented today will become very cheap in a few decades, even if average medical treatment costs continue to rise.
Well, I wouldn't call that "crack resistant", but it's still a good point. The only way to eliminate the chance of having your software get cracked is to make it so terrible that nobody wants to use it.
Medicare is going bankrupt because aggregate costs are increasing. But that says nothing about individual procedures. If we wanted to provide 1950-level care today, it would cost less than it cost in 1950. But we expect better, and so we pay more, even though the cost of the individual pieces has gone down.
If you take the total amount of assets (converted to a monentary value) and divide by the estimated world population, you're in for a shock: That number hasn't really changed in the last 500 years.
Really? Do you have the figures to back this up? Because simply looking at the average wealth in the "West", plus the average wealth in the two most populous countries which, while not super high, is way higher than it used to be, it seems to me that the per capita wealth in the world is a lot more than it was 500 years ago. Yes, some groups are being left behind, but on the whole people are much richer than they were.
Consider, for example, that 500 years ago famine was a fairly regular occurrence. Now people only die of hunger in politically-diseased countries, and there really aren't that many of them. The vast majority of the world has enough to eat. That alone puts the modern day far ahead.
Everything is easily bypassed by crackers. You're probably aware of this, but it's worth pointing out to the readership at large.
You can't crackproof your software. You can't even really make it crack-resistant. No matter what protections you take, your software will come up against some guy who lives in his mom's basement, has a dozen hours a day to spend on the problem, who knows more about cracking software than you ever could, and most importantly who thinks that cricking your stuff is fun. And he will win.
Exactly right for paying for testing. As a glider pilot, the only reason I have a transponder is so that controllers can give other traffic advisories about me, and so that I ping airliners' TCAS units. Other than that I could take it to leave it, as I never fly into class A/B/C airspace. There has been talk of requiring them above 10,000ft in gliders just as is done in other aircraft, at which point the transponder would be very handy. But in all of these cases, if I'm flying VFR and not under positive ATC control, there's a lot more leeway for the equipment, and I'd hope a cheaper ADS-B unit could be made available with that realization.
I don't know a whole lot about the MITRE work besides having seen a test unit once and heard a little bit about it. It was extremely small, perhaps the size of a large-print deck of cards, and the pilot who was testing it had simply velcroed it to the top of his instrument panel. I think the electronics plus a reasonable profit margin were expected to come to a couple hundred dollars. The big question is how little testing/certification the FAA will let us get away with, as that could drastically inflate the cost. MITRE is developing the design with the idea of licensing it to other manufacturers, but I have no idea if any have expressed interest yet. If you google for "MITRE ADS-B" you'll find more information, there seems to be a fair amount of information out there about what they're doing with it.
I can only assume that the OP, like so many clueless Slashbots, is so enamored with conspiracies that he can't even see the reality directly in front of his face.
I can only imagine you're being sarcastic, but I cannot conceive of why. Could you elaborate, please?
Completely unrelated (yeah, right), why is it that 90% of people on Slashdot act as thought their position was the obvious and right and every other position is complete crap, and therefore they have no need to put forth any effort or even sense when posting?
That may reduce the severity but it doesn't eliminate it. For example, if you fire a gun blindly into the woods and nobody's around, not a problem. If you manage to have terrible luck and kill somebody with your blind shot, you go to jail for quite a while (unless they don't catch you!). The fact that you didn't know the guy was there is going to reduce your consequences, but the fact that your action was reckless and resulted in somebody's death makes it still a fairly severe crime, more than what Ms. Drew is getting punished with.
Also, wasn't she a next-door neighbor? She should have had at least some idea of what was going on....
I imagine that it will start out like transponders are now, optional unless you're flying into class A/B/C airspace, in which case I'll simply wait until the initial surge goes down and buy at leisure, since I never fly in those areas. However you raise a good point and many or most pilots won't be able to follow that strategy.
There's a small chance, if you are willing to accept a reasonable aviation price instead of a price that any outside observer would think to be reasonable. MITRE has developed a reference design for an ADS-B unit which runs off a few AA batteries and could conceivably be produced for just a few hundred dollars if the FAA can be convinced to allow less rigorous certification standards for this sort of application. Whether they can be made to see the light remains to be seen, but it's at least possible even if not likely.
The nature of ADS-B is such that there is the potential for ADS-B equipment to be considerably cheaper than traditional transponders. It remains to be seen whether this will be borne out, and I'm pessimistic about it, but the potential is there.
In any case, I never denied downsides, but there are upsides as well. As a glider pilot, I'm excited because ADS-B will probably be considerably more practical to install in an aircraft with a battery-driven electrical system.

NASA had invested $912 million in the project before cancellation and Lockheed Martin a further $357 million.
Is Wikipedia wrong, or do you somehow think that an individual shuttle flight costs a mere nine million dollars?

Please do not use this non-word, it is painful to the eyes.

I'd wager that piracy of such products isn't much of a problem anyway, although I could certainly be wrong.

If you had said "most of the time", I would agree. But I cannot accept that it is always in my best interest.

And you think the 1GB/sec quoted in the title is actual performance in all situations, not just raw read speed?

So if you donate your computer to charity, you may be sticking that charity with the expense of a software license.
God forbid a charity case should be forced to run Linux!
That's no solution, though. He wanted to find out what LiFE stands for, and your proposal assumes he already knows.

There's more to the aviation world than large airliners. ADS-B is a positive step in a lot of other ways.
