  4. Re:unclear whether it's worth it on NASA Gravity Probe Set for Launch · · Score: 1

    So what? It's usually possible to construct a bunch of theories that all describe one particular phenomena (though they don't agree on all phenomena). Should we stop observing phenomena? [...] Well, we should always ask whether a given experiment is worth its cost. But we don't do experiments merely to judge between competing hypotheses. If GPB measured frame-dragging whose magnitude was incontroveribly different from that predicted by GR, then we'd know we'd have to develop a "decent alternative hypothesis" -- even if we don't have any now -- because GR would simply be wrong.

    When was the last time you dug in your yard to see whether there was a buried treasure there? I bet you haven't: you make the reasonable assumption that there is no treasure buried there and digging costs valuable time. Until you receive additional information, the cost is simply not worth the expected benefit.

    When we have a choice, we don't do things merely because we might find things, we do things because we think that there is reasonable probability that they are successful. I don't see that "reasonable probability" for these experiments. When an experiment costs hundreds of millions of dollars, money that could be used for other research with a far larger probability of finding results, we need to do this kind of cost-benefit analysis.

    Besides, while many of them have frame dragging, they don't all agree on the amount of frame dragging. GPB is sensitive enough to measure the strength of the dragging.

    Yes, and what are those alternatives? Are they plausible? By how much do they differ? Can't we distinguish between them more cheaply? I haven't seen a good justification of the experiment in terms of such an analysis. In fact, anything I can find on NASA's site just talks about "verifying two extraordinary predictions of Einstein's theory" and "testing Einstein's theory".

    If you know of a paper (maybe on ArXiv) that actually looks at the possible alternative theories that this experiment lets us distinguish, then please point at it, because most of the justifications of this experiments seem to be fluff.

    You think people write installers for fun? They usually write them because they don't have a choice, because the OS lacks some piece of functionality or other that lets the system adapt dynamically.

    Besides, Mac-style drag-and-drop installs have their own problems: they don't get updated properly and they don't verify or deal with dependencies on install; they just dump the mess into the user's lap.

    Yes, it's nice to include all the dependencies in a single directory. However, there is a reason why not every Gnome desktop accessory includes 500M of Gnome libraries--disk space is cheap, but it isn't that cheap.

    Something like Zero Install should be combined with some form of duplicate file detection or duplicate block detection and sharing. Furthermore, to avoid a lot of tricky bookkeeping, there should be copy-on-write. And that kind of functionality really is best implemented in the file system itself. So, something to think about for the next major release of "ext". (Note that Microsoft is implementing something like this, but they certainly weren't the first to come up with it.)

    Note that the same thing should also happen on downloads: you only download application components you don't already have locally. NFS isn't a good protocol for that, but WebDAV could handle it.

    I'm a lot less disturbed by this "strong authentication" of foreign travellers to the U.S. than I am of all the policies applying to U.S. citizens with no oversight or public review.

    Well, you should be disturbed by them. Contrary to what you may have been led to believe, most of the protections of the US Constitution are not limited to US citizens, they were intended to apply to all people within its jurisdiction.

    But, apart from such legal and political technicalities, think about what both these kinds of policies and your kind of statements send to the world. Basically, they are saying "we don't care about the rights of others; other nations are second class as far as we are concerned; we can treat you like shit, in ways we wouldn't treat our own worst criminals" (foreign visitors to the US already have very few of the legal protections and protection against unreasonable government actin that even US criminals have).

    That kind of treatment has grave consequences for the US. You can bet that European voters who visit the US will increasingly vote for politicians that are not friendly towards the US because of this kind of treatment--what point is there in supporting a nation that commits such gross violations of privacy and treats its allies like that?).

    Furthermore, tourism to the US will probably drop even further, and tourism is of huge economic importance to the US. That's not just because of the increasing invonvenience involved in traveling to the US. It's also because many of the visitors that the US attracts come because the US has a certain mystique as the "land of the free", but that image is hard to maintain if people who come here are fingerprinted, recorded, screened, and tracked.

    This would be a good place to show how someone else buying a diamond hurts you personally.

    Easy. DeBeers sells roughly $5.5 billion dollars per year. What economic activity does that create? Destructive mining in Africa, lots of security jobs (many of them non-US), lots of marketing, lots of real estate investment. It would do you and me and anybody else in the US a whole lot of good if that kind of money instead went into R&D jobs and manufacturing. In particular R&D spending generates far more economic activity per dollar and a far bigger increase in our standard of living than a dollar spent on digging up African mud.

    Saying, for example, that buying diamonds is "lining the pockets of DeBeers" is one of those trivially true things that doesn't tell anyone they didn't already know.

    I bet most people don't know that and don't think about it when buying a diamond. Furthermore, I suspect that most people don't think about what many other people really think of them when they buy certain products that are marketed as "luxury products for image-conscious buyers". We will just have to agree to disagree on our assessments here.

    Why would you assume that people happen to share your values, particularly those people who have decided to go out and buy a diamond? It's all well and good to talk about the bad things that happen when people don't have all the available information, but when you talk about specific decisions, you really have no way of knowing what information those people have,

    I don't have to know because it doesn't matter. If I want to convince you of not doing something by saying "don't do X because it leads to Y", there is no point in explicitly addressing the case where you actually like "outcome Y"--presumably, you'll figure that one out for yourself, and if you don't, all the better as far as I'm concerned.

    Same deal: you're simply assuming that people who don't act in accordance with what you think is the optimal course are lacking information you have.

    No, I merely don't care about those other people in making statements. That's not a personal foible, it's the way language works in the real world.

    If you act in some way because you lack information or haven't reasoned something through, I can convince you. If you have all the information and have reasoned things through for yourself, and you act differently because you have different preferences, then there is no point in taking you into account in such an argument at all.

    Wouldnt it just be easier to pass laws making software vendors responsible for the bugs that they produce instead of spending our tax money to provide a shelter for insecure code?

    Security is an engineering tradeoff, just like speed and usability. I don't want every software vendor to have to conform to the highest level of security out of fear of getting sued.

    The people who should worry about this sort of thing are the buyers of software. If your car mechanic can't fix your car in time because his PC got broken into, you go to a different car mechanic and he will go out of business. If a hotel can't accept reservations because their reservation system got hacked, they go out of business. For small businesses, those kinds of feedback mechanisms work pretty directly and after that sort of thing has happened once to a small business owner, they'll generally have learned their lessons.

    The problem is with non-competitive markets: many people have to buy Windows no matter how insecure it is because the software they need only runs on Windows. And you can't change airlines or banks just because they keep having security problems--there are too few of them around.

    If we create efficient, competitive markets in software, banking, airlines, etc., then the security of software will adjust to the optimal levels demanded by the market. Our problem is not lack of government regulation, it is lack of efficient markets.

    In short, if we want secure software, the government should simply get more aggressive on anti-trust enforcement again. And they should do so first of all against Microsoft so that buyers have a real choice. That's the sort of government activity we need, not bogus "security standards" which aren't going to work anyway.

    What's there to "codify"? What's reasonable about it? There is not a shred of evidence that the "strategy" described in the report will do anything to improve security.

    At this point, we have to conclude that people continue to buy insecure software either (1) because they don't have a choice because of Microsoft's monopoly, or (2) because they don't care about security. If (1) applies, then the solution is to break up Microsoft's monopoly and give people a choice in software; then they can pick the level of security they like. If (2) applies, then what business does the government have to force a level of security into products that buyers don't want?
