  1. All the ports slow down Debian release process on Debian Release Mgr. Proposes Dropping Some Archs · · Score: 1
    I am not a Debian developer, but I have examined some of the mailing list stuff on delayed releases over the years.

    Having to have the installer, particularly, ready and tested across every single architecture is a major reason for delayed Debian releases. So are release-critical bugs in a particular architecture. As one of the vast majority of Debian users who use x86 (actually now just switched to AMD64, which will become more important over time), it seems silly to wait months for a release because the bloody Motorola 68000 series port (to pick a hypothetical example) can't fix their bloody boot disks.

  2. I disagree on Who Will Pay For Open Access? · · Score: 1
    I've done some peer reviewing of conference papers. You don't get paid for that. You get paid bugger-all to be an editor of a scientific journal. Don Knuth, in a widely-distributed letter about this very topic, reports that journal editors-in-chief receive in the order of 6,000 to 20,000 USD per year - and he thinks this is excessive, when, the real payoff is having "editor of Journal of Foobar" on your CV. That's why people do it, not the meager financial rewards. Oh, and the opportunity to have a sneak preview of what everybody else in your discipline is up to.

    And I disagree with your criticism of author-pays. For most academic institutions, a publication at a quality conference or major journal is worth much more than $1500 in research funding - which is what it costs to publish in a Public Library of Science journal. In any case, if you have a paper accepted to a conference, you have to go to present it. If the conference is in another country (and if you're not American, they usually are), it's very likely to cost more than $1500 to pay the conference entry fee, the hotel, the airfare, and so on.

  3. Wonderful but flawed ending on Katsuhiro Otomo's Steamboy in Theaters · · Score: 2, Interesting
    For once, us Aussies saw this film well before you, last year. It was shown subtitled in arthouse theatres in the major cities. If the dubbing is done well, I actually think an English dub would be appropriate considering the film is set in Victorian England and it's a little strange having Englishmen chat away in japanese.

    The movie's plot is geek heaven, being based around the age of steam and the engineers who made it happen. A key part of the film is set in the Crystal Palace for the opening of the Great Exhibition, and it's all beautifully drawn. As others have pointed out, the climactic ending sequence is spectacular, but far too drawn out. But, regardless, this movie is a blast.

  5. The Oracle Problem on Too Darned Big to Test? · · Score: 4, Interesting
    One point that this article doesn't really come to grips with regards to stochastic testing is the "Oracle Problem". In essence, how do you know that the result of testing is the right answer? This is a particular problem with random-input testing, or any testing method that involves using automatic methods to generate a large number of tests.
    #ifdef PLUG

    My own research group works on methods to reduce this burden in a number of ways. One, my personal work, is on "semi-random" testing (we call it Adaptive Random Testing) which, we claim, detects more errors with fewer tests and reduces the problem that way. Another is "metamorphic testing" which tackles the oracle problem more directly by a slightly more sophisticated form of sanity checking assertions. You test the program with two (or more) related inputs, and check whether the outputs have the relationship you'd expect based on the inputs.

    Unfortunately, the boss has an, um, slightly behind-the-times attitude to putting papers on the web; but if you search the DBLP bibliography server for T.Y. Chen you can get references for most of them.

    #endif

    However, I'd be the last to claim that we have a complete solution to the oracle problem; there will of course never be one. But it is a problem that will continue to make automated testing a challenge.

  6. Only defence is be a patent-only company... on Companies Claim iTMS, iPod Patent Infringement · · Score: 4, Insightful
    This is the problem with the software patent situation. As it's virtually impossible to write a non-trivial program that doesn't arguably infringe, say, IBM's patent portfolio, if you actually produce anything you can't sue IBM for patent infringement because they will countersue you into the dirt. However, if you don't actually produce anything, you can't infringe on their patents, leaving you free to sue them.

    So the patent system is creating an incentive for small companies to concentrate on acting as IP toll collectors on ideas reinvented independently by other companies, rather than actually producing products, or for that matter actively selling their IP to companies to produce new products.

    That's my explanation for why software patents are bad for people to whom the ideological arguments are lefty blathering.

  7. hard to export from word proecessor to Latex on OpenOffice.org 2.0 Preview · · Score: 1
    LaTeX is designed for structural document markup, word processors do visual layout. Yes, I know LaTeX lets you tweak the appearance of documents manually, and word processors support styles to some extent, but they are fundamentally different. Getting layout from structure is easy; it's what LaTeX does whenever you run it. Deducing structure from document layout is much more difficult and in fact "AI-complete" in its full generality.

    So, trying to support a more full-featured export than plain text from the OOO word processor might be too much to expect.

  9. Unfair comparison... on German Railways To Get WLAN RailNet · · Score: 1
    Europeans don't as a rule take trains for a 1000-mile trip either. Where they *do* take trains is for trips of up to about 300 miles, where high-speed rail is faster and more convenient (no BS security screening, for instance). Nobody's expecting you to go coast-to-coast by rail.

    What I can't understand is the fact you don't have high-speed rail in the densely populated northeast (and, no, the Acela doesn't count) which could easily support it - not to mention the shitty public transport in most of your larger cities.

  11. Zubrin is a monomaniac on Japan Considering Moon Base, Shuttle Projects · · Score: 1
    Have any of you guys ever met Zubrin? He's a monomaniac about Mars in the same way that Stallman is a monomaniac about free software (though Zubrin's political and diplomatic skills are considerably better than Stallman's).

    This is not a criticism of either person; to achieve great things, you often need an obsessive, forceful advocate for them. I think his advocacy has contributed significantly to keeping a manned Mars mission on the long-term agenda for the space program. But, as you say, he does come across as a little strange.

    I wonder, to take perhaps the most famous historical parallel, whether Spanish aristocrats who funded Columbus regarded him as a bit of a nutter?

  12. Unsolvable with a *classical computer* on Significant Advance in Quantum Computing · · Score: 1
    If you actually read all of your computational theory text rather than just the powerpointy lecture notes your professor gave you, you might be aware of the actual nature of the proof. The proof says that no Turing machine (or equivalently powerful system) is capable of deciding the halting problem.

    Now, the Church-Turing thesis says (roughly) that any computational system can be emulated by a Turing machine - in other words, if it's computable, it's computable on a Turing machine. This is not a mathematical statement; it can't be proven. However, nobody has been able to figure out a remotely plausible way to build a machine that is more powerful than a Turing machine over the past 60 years, so the thesis is pretty much universally accepted, and so the undecidability of the halting problem has been regarded as absolute.

    Kieu argues that the quantum effects discussed in his paper can be used to "compute" useful functions that are not classically computable. If true, this would invalidate the Church-Turing thesis, not the proof for the halting problem.

    I'm not saying the guy is correct; I'll believe it can be done when I see it. But your objection is based on an incomplete understanding of Turing's work. You can read Turing's original paper online if you do a Google search for it.

  13. More to it than that... on Significant Advance in Quantum Computing · · Score: 3, Interesting
    The halting problem cannot be solved for arbitrary Turing machines. Period. No algorithm, as we think of them, using quantum computers or not, will get around the fact that such a solution would create a logical inconsistency (a program could determine whether or not it itself would halt, and then do the opposite, but then it would have been wrong, which it can't be by assumption, and so reality bursts into flames). The only possible catch is that a technique that cannot be encoded in a Turing machine would not cause this particular logical inconsistency to arise.

    You've got it in one. According to Kieu, his system is a non-computable process; you can't simulate what it does on a Turing machine. Hence your objection doesn't apply to his claims.

    However, there are apparently lots of other objections.

  14. Booor-ing... on Significant Advance in Quantum Computing · · Score: 4, Interesting
    Why merely crack RSA and radically speed up quantum physics simulations? That's aiming far too low.

    Instead, Tien Kieu from my university wants to solve arbitrary Diophantine equations using quantum effects. If he's a) correct, and b) it becomes possible to create the required quantum behaviours for arbitrary equation, the following problems become solvable:

    • The halting problem for arbitrary Turing machines, with all that that would imply.
    • The Riemann hypothesis.
    • Goldbach's conjecture

      Needless to say, to say people are sceptical of Kieu's ideas is an understatement, but it's fun to speculate about the "what if"...

    You're probably thinking of the Nth country experiment. One point you may have missed is that the project designed a plutonium-based implosion weapon, not the uranium-based gun-type design discussed in the pop science article.

    To draw a comparison, in later life Isaac Newton spent his time exploring rather idiosyncratic Bible interpretations, not to mention alchemy. That doesn't alter the fact that Newton's earlier scientific work ranks as one of the greatest achievements in science of all time.

    Couldn't you also use an RC plane with explosives and videocam attached as an assissination method?

    Yes. It's called a RQ-1 Predator, and the US military has a bunch of 'em. Your question was probably "could a modestly resourced group of people build something big enough to carry an assassination bomb?" The answer to this is also "yes" - check out this 1/8th scale B-52, and weep at the crash pictures. Note that this thing was designed specifically as a B-52 replica and not as a utilitarian aircraft; if you were designing something like this for real you'd use fewer, bigger engines and a fuselage and wings designed for the purpose.

    Similarly, you could build a UAV to carry drugs across the Mexican border, but that would be a much more difficult task, because of the required payload and range (you'd start to get into things bigger than the biggest commercial RC aircraft). The size required might be to the point where the gadget is quite visible and detectable on radar, which kind of negates the point. I'm not sure about the economics of such a scheme, either; conventional smuggling seems to work reasonably well.

    As for "goodboy" uses, there are plenty. They'd be terribly useful for cops, for instance; imagine if the surveillance capabilities of a police helicopter were available at a tenth the price.

    Given that there's not a huge amount of interest for people at LEO anyway, we should be working on the best plan to explore the Moon (arguably), Mars, and the asteroids (the next logical destination for manned exploration, given the resources available in convenient low gravity) and only then build the infrastructure to do so.

    While Asimov's writings have undoubtedly influenced a great deal of thinking by real scientists about the ethics of robotics and artificial intelligence, the fact remains that they were promulgated in a work of fiction. To my knowledge, go government or professional body has adopted them in real life, nor are they likely to.

    If I recall correctly, Asimov was writing in the context of sentient (or at least the Turing-test-passing approximation of such) robots, which we do not have and aren't likely to any time soon. Secondly, the US military "violates" these laws just about every time it goes to war, if you count Tomahawk cruise missiles and armed Predator drones as robots, and, given their sponsorship of the DARPA autonomous vehicle challenge, they'll violate it left, right, and center if they ever get their hands on more truly autonomous devices. Whether this is morally correct or not is worthy of debate, but Asimov's laws are hardly the last word on the matter.
