Comment Re:What is the business case of SpaceX? (Score 1) 114

They don't do space tourism yet, but once they got the Dragon man-rated I don't see why not. The seven people who've been space tourists so far have in total paid $170 million, while SpaceX has quoted $140 million for a crewed Falcon 9 launch so they're at a price at least some is willing to pay. If they can make the rockets reusable it could significantly increase their launch volume even if only a few hundred super rich want to go. It would be real space flight in LEO and make you a genuine astronaut, not just "pop your head in" suborbital flight. Maybe they could even use the cargo room of the Dragon to hold some kind of deployable/inflatable mini-hotel for the stay. 100 mile high club anyone? ;)

Comment Re:When I was born... (Score 1) 114

When I was born Mankind had not set foot on the moon. By the time I was five, we had been there, done that and decided to never go back again. If aliens do exist, they are sitting back saying "What the f?ck man, you want to meet us but don't have the energy to get off the couch and answer the door?" Mankind does not deserve space travel. We had our chance and refused to take it.

By the time you were five, we had been (384 400 kilometers) / (4.2421 light years) = 9.57827017 x 10^-9 = ~0.000001% of the way to the closest star. Eight years later they launched the Voyager 1 which is now about (127.98 Astronomical Units) / (4.2421 light years) = ~0.05% of the way. And it's probably uninhabited. What chance did we miss to go visit aliens? Do you think if we just put enough money in it we'd invent the warp drive? Chemical rockets can't do it, it'd be like trying to ride a horse to the moon. The ban on nukes in space kills fission, we still haven't got a working fusion reactor here on earth and antimatter only exists in extreme lab experiments.

True, we don't care much about developing the propulsion technology but we sure as hell would like the energy generation technology so to pretend we're not working on it is false. It just doesn't make a whole lot of sense to try building the applied technology before we got the basics working, if we can make a fusion reactor here on earth then maybe we can turn it into a fusion drive. Trying to skip that step earns us nothing, it doesn't bypass any of the problems we already have and creates a whole set of new ones which makes it that much less likely to succeed. The only tech that's pretty much ready to go is fission, but good luck selling a rocket that'll nuke its way through space.

If you'd actually read the linked mailing list post (or even just read the quotes of it in the summary) you'd see that none of the abusive comments are aimed at people, they're aimed at the code. He calls the code a bunch of mean, nasty, insulting things, but he doesn't say anything about the people who worked or released that code. I think the distinction is important here. It's not abuse if there's nobody to be abused.

Secondarily: if you read the rest of the thread, he goes on to work with everyone very productively on tracking down the exact nature of the underlying bugs, posts deep analyses of the code generation differences, proposes a patch for his own kernel to work around this GCC bug, and goes and files the upstream Bugzilla report with the GCC team himself. On the whole I'd say this is pretty responsible and cooperative behavior.

What are you doing bringing objective facts into a Slashdot debate, I mean SWJdot?

The side that apparently blew a 300-civilian passenger jet out of the sky because they're too dumb to know what a Boeing looks like is getting direct military support from a major regional power which just happens to have nuclear weapons. And I thought my hometown of Detroit was fucked.

Well, if you want to put it that way the plane would never have been shot down if Russia had supplied a professional crew instead of teaching the separatists how to aim and pull the trigger. At least with the Russian military firing they probably know what they're aiming at.

Except in this case there's no signs that anyone was being particularly reckless, lazy or disregarding the rules, it was a fairly complex interaction between debug settings, ASM optimizations and dependency management. This is more like when the Space Shuttle blew up and nobody cares about the 9999 parts that didn't fail because the O-ring did and as a result it's now small chunks of scrap metal with dead astronauts. You don't get points for effort, style or the parts that work it's the end result that counts and in this case GCC poops on the floor because the final output is shit.

I think it's a good attitude for a kernel manager, because when he gets shit code from driver or subsystem maintainers that goes into a release kernel and starts corrupting data and throwing panics the shit is going to land on him. You can't just shuffle that responsibility downwards and say no, the kernel is 99% fine but that driver is crap because as far as the end users are concerned the kernel is crap and the internal bickering about whose fault that is doesn't matter one bit to them. It's your project and your job to get it fixed. And that might require some harsh words about the O-ring and the people who made it, because it's making them all look bad which is totally unfair to everybody else.

Comment Re:That's why I dropped AdWords (Score 1) 97

I'm not sure what you're trying to say here, if your AdWord campaigns are being sabotaged it's extremely hard to say what your conversion rate should have been without the sabotage unless you've got really good historic data to show we used to get good leads but now we get crap. For example if my botnet all likes to visit Google and click your ad links, but never buy anything. Yes, you know the conversation rate is very low - as a few real customers are in the mix - but it doesn't tell you anything about who or why, it just looks like random IPs visiting and not buying. Nor do you have any obvious reason to sue, it''s not illegal to visit and leave without buying. To use a real world analogy, it's like you have an organized band to clog up your stores, circulating and acting like customers but ending up just browsing. I've done that in real life, exiting the store without never buying so individually it's not unheard of. But if hundreds or thousands did that in an organized fashion, there'd be trouble as legitimate customers would pass on your store because it's too crowded, even though they have no intention of buying..

If there's a distinct non-human advantage to them, yes. Most sports are extremely tightly regulated, mainly I've looked at the Nordic sports and for example the jump suit used in ski jumping is highly regulated. Likewise in ice skating, they proved some years ago a "Donald Duck" like suit would improve skate times. It was banned. The support biathlon athletes can get while shooting is likewise regulated. The rules themselves are arbitrary, as long as they're equal for everyone. Why it is "three strikes, you're out" in baseball? Couldn't it be one strike? Five strikes? Sure it could, but the game says three. And then you compete under the rules of the game. Everything else is the other way around, they're allowed to wear baseball caps because everyone can wear one and it doesn't favor anyone in particular. You can't call ut unaided because bicyclists obviously outpace runners, pole vaulters outjump high jumpers and so on but the aid is considered neutral. Anything that isn't you ban.

John Stewart Mill made the point that you should consider every argument, even if only one person in the entire world is making it against the consensus of everyone else, on its merits. The person speaking does not matter, only the merits of the argument.

Knowing that someone has a very warped perception of reality - at least from your point of view - pretty much destroys all their credibility to make arguments about the real world. If the argument had any merit then "normal people" would use it too, it's not worth the effort to track every argument back to the underlying root causes. Very often it boils down to "that's not the way real people act or the real world works" because so many get caught up in an ideology and forget to ground their beliefs in reality. They're immune to normal feedback mechanisms, it's like watching people cut themselves and if it hurts the solution is to cut more. I suppose if you cut yourself enough the pain may stop permanently, but it still seems a rather bad idea.

Comment Re:Attention Editors (Score 1) 48

The reason to use [sic] is to indicate that you didn't introduce a typo, it made sense for scribes, typewriters and citing dead tree sources but when you're copy-pasting another electronic source perfect reproduction is the norm and pointing out spelling mistakes is typically mocking, like you're making a point that the one you're quoting can't even spell properly. So I wouldn't use it and if people complain, well then they don't understand the concept of quoting. You don't change someone else's words and it's obvious from context who made the typo so the [sic] is completely redundant.

Surprisingly, no. The vast use of water is for water-intensive crops and for industrial and commercial uses that tend not to be in cities per se.

Should people in cities use less water to maintain lawns of non-native plants that they water during the day when the water evaporates? Sure.

Will doing so radically alter the water usage? No.

The primary drivers are the water-intensive crops (largest) and the commercial and industrial uses of water (second largest).

When doing triage, look at the biggest sources, not the smallest. If you don't fix the hole in their heart, they can't pump enough blood even if you patch the small leaks in the limbs.

Blaming others (e.g. LA vs farmers) is easy and fun, but it frequently accomplishes nothing.

The bizarre thing is I'm actually an optimist, I just don't get bothered by all the stuff I know.

It was very useful when I did counter-terrorism - a lot of people get ultra cynical after that.

Look, everyone tries to freak you out. The engineer part of me always hears them say "choose A or B" and I choose to realize there are mixtures of choices between A and B and besides A and B, some of which are "better" and some of which are "worse" and that choosing something other than A "bad" is probably better than not choosing B "good".

If 1000 people in cities who drive very little and have little environmental impact due to energy etc change a lot, it may be less than 10 people in rural areas changing a small amount. Just alter time of day for watering, use less water dependent crops (rice etc), and you'll be right as rain. Pay attention to native crops and plants and animals and shift towards those and away from non-native ones.

One of the fun things about Seattle is we actually own the entire watershed here. All of it. So the suburbs basically have no water rights.

They either buy it from us at a premium to what our citizens (who own it) pay or they buy it from someone else (at a higher premium since it has to be trucked in).
