    We're doomed to a race to the bottom because no amount of government regulation is going to stop corporations from doing everything they can to minimize costs, which incidentally implies paying their workers as little as possible.

    Yes, and the point of regulation is to remove undesirable (to us the people) things from the set of "everything they can". Minimum wage laws, in particularly, exist precisely to rise "as little as possible" to the point where one can live on that.

    One may as well try to hold back water with a sieve.

    I love that analogy. It starts with using a method you know won't work (sieve) and tries to suggest that thus no method can work, when in reality a bucket will work just fine. That's exactly the kind of deception libertarians and other free-market fundamentalists like to engage in.

    Your effort is futile, however, since this latest economic crash engineered by the financial geniuses demanding free unregulated market has finally driven home to pretty much everyone just what their place in such a society would be. I expect and hope that we'll finally get some toll barriers back up to protect and encourage domestic industries, as well as tight regulation to keep banks and other financial entities from screwing up again.

    ck's advocates are suffering from observer bias. They try his scheduler, and since they know they're trying his scheduler, and since we have a cognitive bias toward seeing what we expect to find, of course they claim it feels "snappier". Of course they can't bring up numbers to support this perception because there is no real effect.

    I haven't tested this scheduler. However, during Con's previous scheduler effort, sound skipped in ZSNES under mainline kernel, and didn't skip under Con's scheduler, in identically loaded machines. However, idle priority was not really idle-only, since a cpu-burning task running at idle priority could cause similar skipping (despite doing nothing but a simple "while(1);").

    That's why, in science, we use numbers.

    The numbers relevant here are the average, maximum and minimum latency, where latency is defined as the time between a sleeping task becoming eligible to run again and it actually starting to execute or a task exhausting its timeslice and the next time it starts to execute, in idle, lightly loaded and heavily loaded machines.

    The argument for a purely forward-looking scheduler that doesn't implement any heuristics is that the maximum latency is a function of the number of tasks running, their priorities, the priority of the current task and whether the task is waking from sleep or has been descheduled due to having used its timeslice. This means that maximum latency is bound (and usually low), resulting in execution that feels snappy (low latency) and smooth (no great variations in latency). A heuristic-using scheduler, on the other hand, can easily end up in a situation where a task is unexpectedly scheduled a lot later than it would in a nonheuristic scheduler; in other words, while the average latency can be low, the maximum is unbound (or at least the bound is very high). These unexpected seemingly random huge latencies (latency variation, to be exact) are what's perceived as "jerky" behaviour, or so the theory goes anyway.

    I agree that we need actual objective data to base decisions on. Does the kernel currently have capability of measuring these things (time when a task starts executing, time when a task stops executing and the reason for it, and a time when a task becomes eligible for execution and the reason for it) and if not, could one be added?

    To demonstrate THAT, you would have to perform multiplication without doing any multiplication or division. Hiding the multiplication by moving the radix point around without calling it multiplication doesn't satisfy the requirements. Moving the radix point around isn't addition. Its multiplication/division.

    Moving the radix point around is taking advantage of the properties of decimal representation. It is, of course, multiplication, and a very efficient form of multiplication; but multiplying by ten can also be expressed as "add this number to itself ten times", and dividing by ten as "find the number which, when added to itself ten times, produces this number". Base-n notational systems have the useful property that when you multiply or divide by n, the only difference in the representation of the final number and the original number is the location of the radix point. That is convenient, but has nothing to do with the theoretical bases of multiplication or division themselves.

    I don't dispute that you can do multiplication without knowing your times tables. I'm only disputing the more abstract assertion that addition is shorthand for multiplication. (ie that multiplication can be defined in terms of addition.) You can for integers, but not it over rational or real numbers. And attempting to convert rational numbers to integers requires the very multiplation/division you supposed to be proving you don't need.

    Every rational number can be written as a fraction. We usually write them as decimals, but that's simply notation. So, in your example 1.5 is actually 15/10 or 3/2 at its simplest form, and 0.8 is 8/10 or 4/5. 3/2 * 4/5 = (3*4)/(2*5) = (4+4+4)/(5+5) = 12/10, which can be written as 6/5 or 1.2, whichever you prefer.

    Please note that writing 1.5 as 15/10 isn't converting anything, any more than writing percentages as decimals would be; it's simply switching notation. Rewriting 15/10 as 3/2 is simply common factor elimination; factorization of an integer is simply a matter of trying to multiply all pairs of integers smaller than that and seeing if the result is this integer (in which case this pair were factors) and then recursively doing the same to them until no further pairs can be found; and that integer multiplication is really just shorthand for addition. This is obviously a very inefficient way of doing problems like this, but that was not the point under consideration.

    Multiplication really is defined in terms of addition, just as addition is defined in terms of the successor function, and exponentiation in terms of multiplication. Look up Peano axioms for details.
