    Technically not, since you could suffocate in it when it is a pure stream. But mixing it back into the air is absolutely no problem at all.

    Taxation should be VERY simple.

    You make $x, then you pay y% of it....no deductions, no loopholes, etc.

    That way it would be fair, everyone would pay lower (for the most part), and taxation would be what it should be for, funding necessary govt. operations.

    The problem with such a simple model is that current pay structures aren't set up for it; the transition period will hurt a sufficiently large number of people that it is "politically difficult" to make the change. Another problem is that a lot of people don't earn very much either; the cost of taxing them is likely to exceed the income received. A relatively simple variation on it is to use a basic banded taxation system. For example, allow everyone to make some minimum without being taxed (which is set fairly low) and then pay y% on everything earned over that. Yes, the formula in the spreadsheet is slightly more complex, but it's still damn close to trivial.

    What's really complex though is when you have different rates for different types of income. Want to really do tax reform? Work on that and you'll get ordinary people on all sides of the spectrum on your side.

    However, I would add, EVERY programmer should know how to or have at least once in their lifetime written atoi() and the corresponding dual itoa() aka, printf.

    There's also the version for people who think they're smart: do the same for floating point numbers. (Experts only: use only the minimum number of digits when converting to a string.)

    People were saying almost the same thing 20 years ago (except not about XML; work on that started in 1996). How long do we have to wait? Is it just the case that Lisp is the programming language of the future, and will always remain so?

    Why would the server render images? That is a piece of client-side functionality.

    Just say NO to Java.

    Just say no to Java in the browser. It's ugly, it's resource-hungry, it's insecure. Java's OK for implementing other types of applications, especially server-side, where the security exposure surface profile is rather different, but the browser plugin part has just been trouble for years.

    [Cloud computing is] pay as you go hosted clustered computing services.

The virtualization is a critical part of what distinguishes cloud computing from what went immediately before, and the business model (essentially based on "very short term rents" though there's more to it than that; the virtualization isn't just at one level and that makes things much more complex) is what makes it more successful. The immediate predecessors were grid computing (which was largely a bust because of the lack of a good business model) and hosted computing (which was successful, but rather slow to spin up and down — order of months, not minutes — and so didn't challenge self-hosting in the same way).

  13. Re:Interface patents on EFF Proposes a Working Code Requirement For Software Patents · · Score: 1

    Thats is the point. It brings attention to the patent examiner that the solution is trivial. More patents will be rejected for obviousness.

    Problem with that is that some patents are clever reimaginings of what is out there. While there are quite possibly other ways to achieve what they describe, the patent is in many ways a description of a piece of lateral thinking that looks at the problem space in a new way that leads to a significantly better solution. Thats very close to what patents are actually supposed to protect when you look at a lot of examples from history of physical inventions, and yet it tends to be "totally obvious" after the fact. Of course it's obvious *now*; you know that thinking in that particular lateral way is a good way to get a solution!

    How to distinguish good patents from bad in the software area? I really don't know. Having the requirement that a software patent only be defensible if there is source code for a solution (in a form that could be used to make a running program, at least at the time of submission) would be a good thing though.

  15. Re:US University Education shocked me... on Ask Slashdot: Is the Bar Being Lowered At Universities? · · Score: 2

    You get shoved in a room with 300 people and lectured to. Having somebody lecture to you about programming is of little use and somebody I know finished the degree without understanding what an array was. The only people who knew how to program were people who learned themselves, and anyone who relied on the university to teach them ended up know nothing.

    It's a proper CS degree, not a "remedial Visual Basic hand-holding exercise". In a degree, you're supposed to do some background reading, some self-directed study. You're also supposed to ask questions if you're having problems. You know what? That's even encouraged. You won't be marked down for trying to understand things. You won't be penalized for not getting it immediately. It's higher education; it's full of stuff that you have to work at to grok properly.

    Can't really comment too much on the undergraduate education programme though; I've only ever dealt with postgraduates as the courses I've given have been a bit too tough without the experience. But I know the undergraduate teachers; they will help if you ask (or even if you just don't hide it from them instead of pretending to be the smartest guy in the room).

    Something you could learn yourself in a short amount of time would be spread over months at university

    Self-directed study is encouraged, and if you're doing it right then you're doing a great thing. If you really want to get good, borrow a copy of Knuth's tAoCP and do as many of the exercises as possible. (Harder version: don't use a computer!) Alternatively, tell your year tutor that you're getting bored by the teaching and want something a bit more challenging; you'll get to find out about the more interesting things that are going on (e.g., the postgraduate teaching or the research-grade stuff). Sitting on your hands and moping is dumb.

  19. Re:Scientific data? on Iceland Considers Internet Porn Ban · · Score: 1

    That sort of thing might well be amenable to scientific data, such as a survey of rapists to find out why they committed their crimes.

    You'd also have to check if it is a predictor or just a correlate. "Breathing air turns men into rapists, because 100% of rapists were found in a survey to have previously been breathing air!" Now if there's an actual causal link, that's much more interesting and a sensible base for public policy.

    Of course, what might actually be true is that doing something (using porn) makes a relatively rare occurrence (rape) some proportion more likely but still not likely, with the major causes being something else entirely; the percentage change might sound large, but the actual effect is still small. In that case, there's a tricky balance of whether doing something that won't make much actual difference balances out the general loss of freedom. Zealots tend to not like such nuances. (Good scientists and engineers ought to appreciate them though.)

    Besides, it's questionable whether the whole concept of determinism even makes sense.

    Even without that, you've got a problem in that a person's mind is clearly a highly non-linear system (one with a very large number of internal states too) and the mathematics of non-linear systems tells us that they tend to be highly divergent; very small errors in measurement can lead over time to very different predicted outcomes. We don't need fundamental physical unmeasureability to get non-determinism; even cell-level models of the brain ought to be completely impossible to use for prediction despite a nigh-on perfect model (itself unlikely).

    Is the universe deterministic? Maybe. Should we behave as if we have free will? For sure. It's either true, or a very useful simplifying assumption that might as well be true to the limit of anything we can sanely measure.
