  1. Re:Bah! on Experts Recommend Keeping Hubble Operational · · Score: 1
    Have you ever been involved in a large project? It's not just the government, its an issue of scale.
    It's hardly even that. Ever had a contractor finish working on your house on time? Big projects, small projects, government projects, private projects, they all usually run late.

    I assume it's because when someone comes up with the original schedule, they never include a bunch of time labeled, "This is for all the shit that will go wrong unexpectedly."

    That provides order, and order = no entropy = no randomness.
    In general, you want to be sampling the lowest bit or two of the audio signal, which should be at the level of amplifier noise in the sound hardware. The actual sounds of the room will be irrelevant if the scheme is properly implemented.

    Similarly, CCDs will have at least a few electrons of read noise, so the least-significant bit will be pure amplifier noise, independent of how much light is falling on the pixel.

    As a port maintainer and committer, I can confirm what you say. The recorded md5 signatures are for the distributed source archive (e.g. from ftp.gnu.org, or Sourceforge, or whatever). They are there to ensure that the source has not been tampered with.

    BSD-specific patches are then applied to the downloaded source, but have no implications for the md5 signature that's on file.

  5. Penn State Astronomy, the House of Usher on Gentoo Package Accused of Violating DMCA · · Score: 2, Funny
    Yes, things like this have happened before. A few weeks ago, it was widely reported that the RIAA complained to the Penn State astronomy department about what they thought were mp3's of young, black R&B star Usher.

    In fact, they were mp3's of original a capella music about astronomy. On the same web page, there were references to Prof. Emeritus Peter Usher, an elderly, white, generally unhip astronomer whose recent contributions to the field include an analysis of the astronomical context of Hamlet .

    The good folks of the department were kind enough to issue widely-distributed press releases mocking the RIAA, who later apologized for the error.

    That reminds me. A couple of years ago, I was wondering how easy it was to get prescription drugs on the Internet without seeing a doctor. I went to a web site that sold birth control pills.

    To get the pills, I had to fill out a questionnaire with my medical history.

    No, there was no possibility that I was pregnant.

    No, I had no history of reproductive illness.

    No, I am not a smoker.

    Yes, I understand that the pill does not prevent the transmission of STDs.

    And so forth.

    I submitted my answers, and it proudly announced that I met their criteria and could go on the pill. They were all set to send them to me. I didn't go through with it, though, because of one little thing they didn't bother to ask about... I'm male.

    When it comes to grammar and spelling, there really shouldn't be any points of view.
    I'll offer a third point of view. It was an error of diction.
    ``Diction is a general term applicable alike to a single sentence or a connected composition. Errors in grammar, false construction, a confused disposition of words, or an improper application of them, constitute bad diction; but the niceties, the elegancies, the peculiarities, and the beauties of composition, which mark the genius and talent of the writer, are what is comprehended under the name of style.'' --Crabb.

  13. Re:virtual servers on Managing Batch Jobs for Several Time Zones? · · Score: 1
    I think you just need an ordinary chroot, and there's no need for separate NTP daemons. In each chroot, you have a separate /var/cron/tabs to store the crontabs for that TZ, and a separate /etc/localtime to specify the TZ. Then you run a cron in each chroot.

    This approach assumes that the tasks you want to perform are practical inside a chroot or jail.

  17. Re:"Worthless Navigation Systems" on Hardware-Based Commute-Map Gadget · · Score: 1
    I agree about the NSX not having much widespread influence, and would say the same about the A8 (since it's a $70k car). That the NSX still costs as much as it does, with so little improvement since its debut, is a shame. It should sell for $70k or less as well these days.

    But the aluminum A2 is an interesting development, and hopefully will lead to more widespread use of aluminum. I see from your link that Honda use an aluminum unibody on the Insight, which is still fairly low production and has high manufacturing costs, but is at least an improvement over the NSX in that regard.

    No, What it *Should* be is that there all cars are identical and provided by the race authorities which are assigned to the drivers at random on race day.
    No. That's how you would run a racing formula that's designed as a driver-vs-driver competition. Formula 1 is the pinnacle of automotive technology; it's as much an engineering competition as a driving competition. That's not a flaw, but rather (to a great degree) its purpose, and one that should appeal to geeks! Within the formula (which specifies engine displacement, general form of the chassis, fuel, etc.), who can build the fastest car?

    There are other racing formulae that require more nearly identical cars, and that's great. There should be pure driver-vs-driver competition in motorsport. But there should also be engineer-vs-engineer competition as well, and this is what Formula 1 provides (albeit imperfectly).

  20. Re:What's with all these doctored photos?!? on Hubble Catches Some Cosmic Fireworks · · Score: 4, Informative
    While some of your criticisms have merit (such as superimposing the image on a separate starfield), some are off base.
    The image is created through "observations" from Hubble, the important part being the fact that they use plural form. So the colour portion of the pic is a composite from two or more pictures. The colours are so vibrant you have to assume they're retouched,
    No professional telescope uses color detectors. They use monochromatic CCDs behind various filters. These filters are chosen for scientific purposes and are not designed with human color response in mind. They may even be narrowband filters that only pass a single emission line, e.g. from hydrogen. Thus, any color image you see from a professional observatory will be combined from multiple exposures, and will be subject to artistic interpretation. Trying to mimic "what it would really look like" is, to a great extent, a lost cause; most things you look at through a telescope appear pretty washed out, but part of that is that the image is faint, and we're using our color-insensitive rods to see. And the filter set used may not be amenable to recreating human visual response. And the interesting detail may be in the infrared, or the near ultraviolet, which we cannot see. Or the detail may be in emission lines; where the emission from hydrogen is vs. the emission from oxygen.

    People need to understand that HST isn't a big Canon digital camera. There is a lot of work involved in "reducing" astronomical data into a usable form, whether for science or PR. It makes no sense to use terms like "retouched." Raw data, as read out directly from the camera, is pretty much useless for any purpose. If I have an imaging run of a couple of nights at Palomar, for example, it generally takes at least two weeks (of long days) to get that data into a scientifically useful shape, at which point we use it to select objects for further spectroscopic study. After obtaining spectra, it takes more weeks to get the spectra into useful shape. Then we can start the long process of measuring scientifically useful things and learn something.

    In addition many of the stars have lens flares which would destroy any scientific value they had which means the lens flares were Photoshopped in afterward!
    I think you're referring to the cross-shaped diffraction spikes around stars, not lens flares. These are real. They are caused by the diffraction of light from the stars by the cross-shaped secondary mirror supports.

    Don't worry about "destroying any scientific value." Telescope time is precious, whether on HST or any top observatory on the ground. You get diffraction spikes around bright objects (at least "bright" by the standards of the telescope). There's no way that the bright, spikey stars were the scientific target of that image. There's no way you would waste telescope time by exposing so long that your science object saturates or is surrounded by big diffraction spikes.
