  1. maybe they could rent? on Ships Turned Away As Aussie Customs' IT System Melts Down · · Score: 0, Offtopic

    Isn't there a Beowulf cluster available when Peter Jackson doesn't need the cycles?

  2. Re:Give me a break! on Gates Donates $15M to Preserve Computing History · · Score: 3, Informative

    give me half that money and I'll double the size of that collection

    Having gone through the museum twice, I can tell you that the collection on display (less than half their actual inventory) is irreplaceable. The very first Apple I, with Woz's signature, is there. Several other artifacts are similarly unique. You may be able to double the inventory, but you would lessen its actual value in the process.

    However, the funds are not all for the collection. The Museum also needs operating funds, such as very strict climate control (typical for a museum), building maintenance, insurance, and material expenses for cataloging, handling, and restoration of the artifacts. The material expenses are unique, due to the Museum's unique inventory and the stringent policies regarding restoration.

    You didn't read the link I posted

    When you lead off with a comment that is demonstrably false, why should I bother?

    But of course that's for one process vs dtrace that looks at the entire system.

    "strace -f" can follow the entire subsystem you want to trace.

    Stop being such a fanboy and RTFM.

  5. Re:kprobes? on A Comparison of Solaris, Linux, and FreeBSD Kernel · · Score: 1

    Really ? Well imagine it like this : I have application X that is extensively used in the market for "mission critical" sort of work.

    OK, I'm with you. My company has exactly that.

    Now somehow/somewhere a client hits a problem and blames *MY* product.

    And then they call me. I'm the support guy. Chances are, if their system worked before they installed application X, and stopped working after, then the problem is with application X.

    unless you do find out the issue, neither the customer nor Sun is going to lift a finger to help you

    Not the case when you have something they decided they want. They'll help you. They'll even bend over backwards, to a point, and they expect that you'll do the same. Unless you don't care about the sale and your company's reputation, you will.

  7. Re:kprobes? on A Comparison of Solaris, Linux, and FreeBSD Kernel · · Score: 2, Interesting

    For the typical user app, profiling is the answer. A program bottleneck, such as a file being read over and over, will be revealed in profiling. A bottleneck in the kernel needs to be resolved in the kernel, not in userspace.

    This is not meant to disparage Solaris dev tools. This is merely to point out that Linux has its own, very powerful developer-oriented tools.

  8. kprobes? on A Comparison of Solaris, Linux, and FreeBSD Kernel · · Score: 2, Informative

    While not entirely equivalent, kprobes do give you an excellent way to examine and monitor the current system state.

    However, the quality of a kernel is not automatically improved by the inclusion of DTrace. Not to disparage Solaris and FreeBSD, but DTrace is primarily for kernel developers and sysadmins. The common user and app developer have little use for either DTrace or kprobes.

  9. of course, it's e on Your Favorite Math/Logic Riddles? · · Score: 1

    Of course. I figured it would be a transcendent number, I just didn't know which one. And somehow, e never crossed my mind. Thank you to both, croto and sam_nead.

  10. the nth root of n on Your Favorite Math/Logic Riddles? · · Score: 1

    f(x)=x^(1/x)

    It is not defined for negative values or 0. It is defined only for x>0. At 1, f(x)=1, then it peaks somwehere in 2.71
    What I'm really interested in is the first derivative. Where f'(x) is 0, is the maximum of f(x). Just one catch: no limits in the formula. I don't want something that I need to calculate forever; I want a formula giving me a value I can calculate to an arbitrary precision.

    The problem comes into play with the (1/x) in the exponent. All attempts to derive this result in a formula which contradicts itself, due to 0 being in either the base or the denominator of the exponent in the original f(x).

    It is defeating all attempts of my college-intro-to-calculus. Searches at wolfram.mathematica.com don't help, either (or I'm just doing the wrong searches). Who can help?

  12. How do they verify their "creation"? on Researchers Reconstruct 1918 Flu Virus · · Score: 1

    Rebuilding an entire genetic sequence like this seems like a lot of room for mishaps. It's one thing to modify an existing sequence, and another to build up from scratch. How will researchers confirm that their new "baby" isn't some mutant Frankenstein-monster strain? Will they infect someone and then watch the symptoms, to compare against the epidemic accounts?

  13. but he hasn't accounted for human nature on Ray Kurzweil's "The Singularity is Near" · · Score: 1

    Say what you will about the innate good and/or evil in humanity. There have always been people who want what you have, simply because you have it and they don't. Until the time comes that human nature itself changes, all these wonders of technology will remain neutral tools, reflecting their flawed users more than any utopian vision.

    I think iptables (or some such packet filtering system) would be your friend here. Whatever comes from his wireless NIC has a particular Ethernet address, the first tool of your filtering.
