Comment Re:Not at fault, but was it avoidable? (Score 1) 408

... the real question is, "Were the accidents something a human driver could have avoided?"

It's an interesting question. On the other hand, most collisions are something a human driver could have avoided somehow...but didn't.

Sometimes you have to yield right-of-way because it's clear the other driver isn't going to. Do autonomous cars know that?

I would be shocked if they didn't "know" something like it. I can't imagine any car (let alone the entire group of 44 which didn't have a collision) doing a full year of city driving without encountering multiple situations where another driver failed to appropriately yield the right of way.

Comment Re:Small Airports Have Advantages (Score 4, Insightful) 203

As a New Yorker, I much prefer LaGuardia, and strongly disagree with calls for its closing.

The point is, I think, that in exchange for an improvement (real or hypothetical) in convenience for a small fraction of total air travellers, there is a substantial and arguably unnecessary burden of cost and inconvenience to the entire system (which is ultimately paid for out of everyone's pockets--and user experiences).

I would love to see these large airports replaced with multiple smaller airports. A larger percentage of the population would have an airport nearby, and average travel times would be reduced significantly.

Well no, it wouldn't. A fully-served point-to-point network with n nodes (cities served) has on the order of n squared links between nodes. The number of passengers desiring each direct link gets to be very small, very quick, meaning infrequent scheduled flights on small, underfilled, costly-per-seat aircraft. So what happens is that airlines adopt (to one extent or another) a hub-and-spoke model. Most direct point-to-point routings are dropped. If I want to fly from East Podunk, NY (POD) to Los Angeles, I can't get a direct flight POD-LAX. Instead, I get a hop to an airline's hub (JFK or ORD or DTW or wherever), and a connection from that hub to LA: POD-JFK-LAX, or POD-DTW-LAX, or POD-ORD-LAX.

If I want to go to a destination served by a smaller airport (let's call it West Lemon, CA: LEM), then I'm taking three flights: spoke to hub, hub to hub, hub to spoke: POD-JFK-LAX-LEM. And each of those flights carries with it the time penalties associated with loading and unloading passengers and cargo, and a risk of delays or cancellations due to weather and other circumstances--plus the plain old waiting for connections, because service to and from the small airports at POD and LEM is infrequent.

Worse still, all those little commuter flights linking the regional airports to the major hubs are going to take up gates and takeoff and landing slots at those busy airports, slowing down the whole system and/or pushing those less-important flights to less-desirable times of day. Taken all together, offering frequent (or even just daily) service to a lot of small airports is going to mean a lot more flights of a lot more smaller aircraft, and/or passengers frequently making multiple connections. It would be expensive per-seat and vulnerable to failures and delays.

Now, La Guardia is an interesting case. Since it's right next to downtown New York, it draws a substantial number of departing or arriving passengers, and enjoys a kind-of-weird pseudo-hub status for historical reasons. Practically speaking, though, it means that there are effectively two hubs (LGA and JFK) or even three (if we count EWR) serving the same area, resulting in needless duplication of services. Routes that could enjoy frequent service with inexpensive (per-seat) full-sized jets get less-full or more-expensive aircraft, or less-frequent services divided between two or three New York destinations. Local New Yorkers enjoy the appearance of convenient, direct flights, at the cost of making the rest of the system a bit worse and a bit more expensive for everyone.

police injury rates are _much_ higher than most work

Welp...sort of. The U.S. BLP recently published their 2013 census of fatal occupational injuries. The overall fatality rate for the workforce was 3.3 fatal injuries for every 100,000 full-time-equivalent workers per year. Management employees averaged 2.4; sales 1.6--no surprises there, really.

For employees in the "protective service occupations" - police, firefighters, correctional services, animal control, security guards, and so forth - the rate was 6.9 fatalities per 100,000 FTE. (I haven't been able to find data broken out by occupation within the category. If someone can find that, that would be great.) So that's what we expect--police, firefighters, and others do have a riskier job than the average, and riskier than the typical office worker. Somewhat surprisingly, the relative risk is only a factor of three or four different when comparing a police officer to, say, an IT manager.

But...there's the rest of the table. "Intallation, maintenance, and repair" occupations? 7.2 fatalities per 100,000. "Construction and extraction"? 12.2. "Transportation and material moving"? 14.9. "Farming, fishing, and forestry"? 23.9.

The real manly men, in real danger on the job, are apparently out there working with tools, building stuff, drilling for oil, driving big rigs, and cutting down trees.

And let's be honest--a lot of the injuries and fatalities sustained by police officers aren't directly attributable to violent suspects. A big chunk of them come from the fact that the typical frontline officer spends a lot of time moving around--in a patrol car, on a motorcycle, on foot, or on a bicycle. Special laws protecting police officers from insults don't actually reduce their likelihood of being in a vehicular accident, or getting clipped by a passing car during a traffic stop, or slipping on an icy sidewalk in the winter. Looking at the last ten years' police fatalities for the United States, the total number of officers killed in motor vehicle incidents (car and motorcycle crashes; hit by car) is 605. The total number of officers fatally shot, strangled, or stabbed is 553. (And I suspect that the proportion who get shot is even lower in Canada.)

The elaborate charade is all about convincing Congress that the negotiation is so complex that the president NEEDS fast-track authority to get this whole deal done.

Well, Bush asked for this kind of authority too, so do note that this not particular to Obama. The real reason the president wants this is to prevent individuals from tagging on bill busting riders where the president would have to veto his the agreement to stop some unacceptable after the negotiation condition from taking place which is exactly what the person wants who tagged the rider onto the bill. I never hear about other countries having this kind of problem. Can you imagine if you agreed to buy a house at a certain price and then you show up for closing and the owner says "Surprise! I never told you this before, but you have to buy me a new BMW to get the house." Nobody would go for that. But doing similar things in legislation is completely OK apparently. If you don't understand why all presidents regardless of party affiliation can't trust Congress to just leave the agreements alone before voting on them, then you don't understand why this is necessary.

A commercial plane will most probably undergo through several maintenance events and checks during that sort of time frame, where cycling the power is part of the procedure.

It's very reassuring to know that it probably won't happen.

As other posters have noted, 248 days of operation means skipping twenty-plus maintenance and inspection cycles, plus missing one or more engine overhauls. That sucker's going to fall out of the sky due to a hardware problem before the software error gets the chance.

Even in the absence of regular, scheduled, required maintenance, there will be hardware failures due to stuff wearing out, with sufficient frequency to force reboots at less-than-eight-month intervals. Honestly, the FAA is going to ground any airline that was so lax as to get within six months of tripping over this bug.

That's not to say that this bug is a good or acceptable thing, nor that something like it couldn't have much more serious effects. But this particular error is a non-issue from a real-life consequences standpoint.

I don't know about the technology or the algorithm(s), but the linked article is certainly nonsense.

“You could use the same basic framework to do robust decision making like trying to come up with insulin and glucose monitoring plans [for diabetes patients],” says Neil Burch, a computer scientist at the University of Alberta who helped design a poker-playing AI earlier this year. “You get regular snapshots of glucose levels, and you have to decide how much insulin you should take, and how often.”

Do courts give grovelling apologies enough weight that this 'contrition' is a logical strategy to try to reduce any awards of damages? Are such apologies sometimes added as conditions of a settlement, presumably so that the victor can grind the vanquished further into the dirt? Is there some other advantage to issuing one?

I'm not a lawyer, but as an informed layman I can only point out that in some/many/most cases, juries and not judges determine damage awards. Based on the juries I've served on, I can tell you that a rather large amount of people on a jury don't know anything about technology and thus tend to see this kind of thing in real black and white terms where they overvalue the "damage" that the defendant does. I've never served on a jury where this strategy would have made any difference in the damage awards, but they may be gambling that just giving up may stop the lawsuit in that the music companies may find it cheaper to reach a quick settlement where the founders/owners agree never to do this again than to try to get blood from a stone and squeeze money out of the defendants. Given that it was likely going to be a slam dunk in court to prove that Grooveshark violated copyright law and failed to pay legally required licensing fees, giving up and apologizing is probably the best choice out of a bunch of not very good choices. I've seen people and companies fight in court when it's been ridiculously easy to prove that they were in the wrong and the results of that have often been financially disastrous to the defendants.

Because, I know I wouldn't.

I understand your point, but in the case of individuals, most non-techies are often too embarrassed to ask a technical person for help in such situations, so they just pay and hope for the best. In the case of businesses, I can tell you as someone who works in IT for a Fortune 500 company and has to deal with IT staff in much smaller companies on a regular basis, smaller companies often don't have the best IT people. A lot of times I see that small companies just hire whoever they can get for the bottom tier wages they pay because they don't respect the job and they would outsource it to India if they really could do so. The IT staff of such companies are just barely competent enough to deal with most ordinary situations that come up and anything out of the ordinary like this gets way out of their comfort and knowledge zone. Maybe they have backups, but to actually verify those backups? Keep hashes? Probably not on both of those.

Comment Reasons why people become hostages (Score 5, Interesting) 334

I've been thinking about this for a long time, especially after the rash of hostages killed by ISIS. At this point, nobody can really claim to not know the danger. I know nothing about Lo Porto but Weinstein clearly knew the dangers. So we did he stay there? I think there are several reasons why westerners put themselves in deliberate danger in places like Pakistan, Syria, etc.

1) Some people are simply mentally ill. After the first Japanese hostage was killed by ISIS, it came out that he was mentally ill. Not mentally ill enough to need to be locked away, but clearly incapable of making rational decisions regarding his own safety. People like this are simply always going to gravitate towards dangerous places because the internet makes sure that they know where the really dangerous places are.
2) Some people believe that they are special and the bad guys won't go after them because they are "helping". Most of the hostages fall into this category. Weinstein was like this. Alan Henning fell into this category and possibly the first one as well. Reports are that Henning believed to the very end that the fact that he was there to help would save his life. Sometimes these people get away with being in a dangerous location once and they think that they are simply lucky and won't ever be harmed. Henning went into Syria several times and was left alone. The second Japanese hostage executed by ISIS went to help the first one and he went because he'd been to the area before and thought he was special and the bad guys would leave him alone.
3) Some people are so overcome with their desire to help others that they can't rationally assess the danger and while they know if they are captured it's going to end very badly for them, they believe that they will simply beat the odds. Remember many years ago when Americans and Europeans volunteered to be human shields for Saddam Hussein? They were like this. A few months ago it got announced that a young American female hostage was supposedly killed in a bombing raid against ISIS. She had operated in the area previously and had to know the danger, but she believed that because nobody had yet bothered her that she could work there at no risk. She died as a result of being wrong about that.

There's some overlap between those vague 3 reasons I gave for people ignoring the real danger to be in places like Pakistan and Syria and so on, but I don't know how we can ever stop people from willingly becoming victims of their own bad decisions about personal risk.

Comment Re:Public domain? (Score 3, Interesting) 309

Does anyone know if *any* work has become public domain in the last few years in US and Canada? From what I see it just sounds like anything that's was copyrighted will now forever be copyrighted as copyright gets extended by X years every X years (with X=20 here).

In the USA, the answer is "no". Unfortunately, some years ago the classical music label Naxos got greedy and put out a CD in the USA of a 1930s classical work, specifically Pablo Casal's recordings of the complete Bach cello suites. In Europe this recording had clearly entered the public domain, but not in the USA. In fact, there was no question that it was still under US copyright at the time Naxos put it out. Not only was it under copyright, but the US copyright owner (Capitol Records) had their own copy in print and sued Naxos for copyright violation. It was really idiotic for Naxos to try to get away this in the US market and they lost the case. But a worst case scenario happened in the case. The court that heard it (in my opinion) basically made up the law and came to the conclusion that every recording every made or sold in the USA, even as far back as Edison's first attempts in the late 1800s, was still under copyright in the USA because they basically claimed that "common law copyright" protected them until the US law covered them. Naxos couldn't really appeal this because they had no way to argue that what they did was legal, so this horrible court decision that all US sound recordings are still under copyright became US law. Short of convincing Congress to pass a law on the subject, we're basically screwed now as there's nothing ever recorded or sold in the USA that is in the public domain at this time. Do note that this crazy legal finding doesn't apply to books, movies or anything else.
