  1. Re:Sig Figs? on State Dept E-mail Crash After "Reply-All" Storm · · Score: 1

    There's ~47,000,000 Americans without health insurance. Out of a population of ~300,000,000. That's 15.67%, not 50%

    I don't know anything about those source numbers, so I'll just go ahead and believe them, but I've gotta call you on those sig figs there. 15.67? 4 sig figs? How about just 20%.

    (I'm not sure whether to thank or to blame all of my physics teachers for drilling us in sig figs)

    Both 47,000,000 and 300,000,000 are both to two significant digits. Calculations involving those two numbers should have two significant digits in the results. 4.7/30 is .16 to two significant digits, while .2 is only one significant digit. How about actually using what you supposedly learned about significant digits?

    Access to records are ruled by the Freedom of Information Act. For non-personal information requests, you need give your name, address, daytime telephone number, information on the records you are looking for, and an agreement on amount of fees you are willing to pay. For personal information, you also need a bunch of info on the person (subject), a notarized signature or Under Penalty of Perjury Statement (see third link), and a statement authorizing you to receive the subject's personal information (assuming you are not the subject).

    Except you have broken the code, most likely: if (issue1 || issue2) { needs to become if (!needs_cleanup && (issue1 || issue2)) {. Really, good error handling is hard to get right.

    Geez, just as I was about to submit this, I noticed that it was jd142 that made the initial error, and it wasn't caught.

    Since I am editing again, I just want to say that the goto as written above really is just a finally clause, as you get in Java. These are really the types of gotos that actually have reason to exist -- or have people not written try { ... } finally { ... } in Java?

    You can not copyright a name. I think the summary writer misread or misunderstood the line in TFA:

    The Popeye trademark, a separate entity to Segar's authorial copyright, is owned by King Features, a subsidiary of the Hearst Corporation -- the US entertainment giant -- which is expected to protect its brand aggressively.

    The name Popeye is trademarked.

  8. Re:Why not raise the tax on gas? on Oregon Governor Proposes Vehicle Mileage Tax · · Score: 1

    Gas is elastic in the long term, but is actually inelastic in the short term.

    What affects demand? When there is a long term trend (like what we saw recently), changes in lifestyle occur. People/companies buy efficient cars/equipment, move closer to work or otherwise reduce usage, or avoid the cost almost entirely by buying bus passes and such -- all of these are largely multi-year commitments. That is what happened as a result of the 70's crisis, for example -- in particular, California's energy consumption has not kept up with it's population surge since the 70's.

    However, when short term fluctuations occur, people do not rush to change their habits. Instead, they hope prices will go down next week and maybe don't drive as far for vacations. That's why gas prices rocket up and down so fast from day to day -- they could not do that if the prices were elastic (compare e.g. food).

  10. Re:Congratulations on RIAA's Request For Appeal Denied In Thomas Case · · Score: 1

    The only copyright that they would have is a compilation copyright -- that is, which poems they chose and how the poems are arranged on the page. Oh yes, and a regular copyright on any original work added. So, there is no copyright on the poem, but there might be on a scanned image of the page containing the poem. Oh, and just because there is no copyright does not mean they can't sue you for it or try to convince you they have one (they seem to have done the latter successfully).

    This is going to be the same for any group of prime numbers you pick.

    Counter-example: I pick 3 and 5. 3x5+1 is 16 which is not prime. The demonstration is only valid is you pick all the first N prime numbers.

    Read the post again:

    31 therefore is either a prime number itself, or it can be broken down into a product of prime numbers.

    But we've shown that the prime numbers in our list can't be the primes that do that, since none of them can divide into our result cleanly.

    So, 16 is either a prime number itself, or it can be broken down into a product of prime numbers, and the the prime numbers in your list can't be the primes that do that. In particular, the prime you are looking for is 2.

    Especially since the statement is "The students will essentially own the computers." Given that that is the intent, then they need to be managed accordingly. That means minimal controls/intrusion, just enough to satisfy the requirement: "The state mandates web filtering on all machines." There is no way one can stop kids from doing things with the machines, nor does one really want to.

    As far as lock down, security assumes no physical access. How do you handle someone who reformats the drive? And disk target mode? Resetting passwords with an install disk? Really, trying to stop someone from doing something to a laptop that they have most of the day every day is not going to work. Do the minimum and forget about it: don't ask don't tell. At home, parents can police. At school, they are watched already.
