  1. Ahead of Schedule on New Theory Explains Periodic Mass Extinctions · · Score: 1
    This cycle would come due in 7 million years from now:

    Over the last 500 million years or so, the number of species on Earth has tended to dip regularly about every 62 million years. The last time this happened, about 55 million years ago--or about 10 million years after the great K-T extinction event that wiped out the dinosaurs--biodiversity sank by about 10%; around 115 million years ago, it dropped by a similar amount.


    But we're already in possibly the biggest extinction event on record:

    7. Present day -- the Holocene extinction event. 70% of biologists view the present era as part of a mass extinction event, possibly one of the fastest ever, according to a 1998 survey by the American Museum of Natural History.

    We can't blame this one on the Sun's distant future interaction with the Galactic Ecliptic. We've been working for this one pretty hard ourselves already.

  6. Re:Concentration Is Good on New Record For Solar Cell Power Efficiency · · Score: 1

    No, concentrators can be made with all the optical absorbance characteristics of the actual cells, but cheaper. Optics says they are proxies for the collector. The only problem is making them closest to perfectly reflective/transmissive (100% efficient), even as dust accumulates. But otherwise there is no limit on concentrators that doesn't also apply to the cells. Except that concentrators are cheaper.

  7. Destruction Protocol on DSS/HIPPA/SOX Unalterable Audit Logs? · · Score: 1

    And how about tech and biz processes to destroy all those archives once they're expired?

    The US has gone in the opposite direction of the rest of the modern world, requiring data retention by business, healthcare, telecom (but, not ironically, by government). The rest of the world has data retention laws and practices requiring data be destroyed once the original transaction dependent on it has completed, and after any reasonable auditing latency has expired. These archives are piling up. Not only is storing them a waste of space (virtual and physical) and tracking them adding complexity to management. They are also the stuff that privacy invasion is made of.

    If the IT industry ensures that archive expiration and data "termination" is always part of the process, built into software and business processes to extend "archive/restore" into "archive/restore/delete", we will make our jobs easier. And we will make protecting our privacy that much easier.

  8. Re:Concentration Is Good on New Record For Solar Cell Power Efficiency · · Score: 1

    Ah, but as you point out, that heat can be recaptured.

    I didn't say there's no upper limit to concentration multipliers; I just quoted the summary's "20x". So I assume 20KW:m^2 doesn't damage the system, but rather drives it to higher efficiencies.

    I wonder what kind of mechanism could get maximum efficiency at really high concentrations, driving the collector material to its Gibbs Free Energy threshold, and actually driving all the electrons into an anode or something.

  9. Concentration Is Good on New Record For Solar Cell Power Efficiency · · Score: 3, Insightful

    Concentration of a larger solar input area onto a smaller solar cell is nearly always better than straight 1:1 reception. The efficiency goes up with these materials, which of course is good.

    But also the concentrators are a lot cheaper than the cells. The concentrator is usually a cheap (compared to the cell) lens or mirror. So a 20x concentrator gets 20x the input energy, but for a much lower cost than 20 cells. And that cell is operating at higher efficiency, on 20x the input. So a $10 cell fed by 20 $5 concentrators costs only $110 instead of $200. 5% more efficiency in the cell is applied to all 20 concentrators, not just the 1 cell, for 200% efficiency. So it's double the efficiency at 55% the price, or over 3.6x the $:energy efficiency. In reality, the concentrators are better than 5x cheaper, and the efficiency gains can go higher than 5% greater.

    And then there's all the savings from cheaper replacement concentrators, which could even last longer than the cells (though the cells typically last >30 years), and dropping all the other HW from the 19 (or however many) extra cells in favor of "dumb" concentrators. In fact, since concentrators are so cheap, the cells might not require HW to track the Sun for maximum absorbtion, but just array the concentrators in an arc (or bubble) that always leaves an array of concentrators facing the Sun (and the rest off-axis), without consuming energy to move. Or extra parts, or computing, and saving all the maintenance costs, too.

    So the more concentration, the better. After all, that's how the engineers thought up this stuff.

    All they've announced in over a year and half is migrate the repo to SVN. I was right to stop watching their paint dry.

    Now, a microkernel Linux with userspace modules that runs Linux apps would be good, and develop much faster. But since Linux apps call syscalls, which the kernel would have to accept even as just a proxy API to userspace kernels, and that swapping would ruin any performance gains, such an architecture is probably merely academic.

    Not necessarily. There is a case that VM must be mediated by a privileged OS, or the memory spaces aren't really separate. But the IPC itself can be in userspace. Consider how much already is: shared text config files. Databases. Network sockets, except for the access to HW. Why can't a userspace process accept messages from processes addressed to other processes subscribed to the daemon? Even secure IPC can be in userspace, with app-signed tokens.

  16. Re:Scheduler Nanokernel on The Completely Fair Scheduler's Impact On Games · · Score: 1

    That's what a kernel is, but not the Linux kernel. Linux is a monolithic kernel, including all kinds of stuff that isn't the scheduler, isn't the driver API (or just the drivers too). That's why Torvalds correctly said that the scheduler is a tiny part of the kernel.

    If customizing Linux to the specs I mentioned were so easy as downloading source and compiling (you skipped the hard part, factoring and looping back the extra codepaths), then all the distros that try it (probably starting with the "Linux on a - 1.44MB - floppy" ones in the mid 1990s) would be trivial. But they're not.

    FWIW, while I don't want to swap out my ALU HW, many recent advances in CPU take exactly that approach, like the Cell sacrificing CLU die space for extra ALUs and parallelizing HW. In point of fact, one reason I'd like a nanokernel would be to run on something like the Cell with embedded (or just Tbps-bus-bridged) FPGA. Linux's current architecture is far from serving that architecture.

  17. Scheduler Nanokernel on The Completely Fair Scheduler's Impact On Games · · Score: 2, Interesting

    Schedulers are actually not at all that important in the end: they are a very very small detail in the kernel - Torvalds
    Actually, I'd like to see the OS kernel consist entirely of only the scheduler and the thinnest APIs to secure drivers granting access to the HW. Everything else, including IPC, could be in userspace.

    That would make distributing the OS a lot easier. And the simplicity could be a lot easier to secure, to develop for, to customize a deployment for minimum HW (like eg. a "self-winding" 10mW Bluetooth ring with "accessory" features). Practically every device could run the same "OS", with modules bolted on for increased functionality on heavier HW.

    I didn't say there were no criminal Democrats. I said the magnitude of Republican criminal conspiracies is much bigger than that of Democrats.

    I see you list, and I raise you just (a subset of) the Abramoff list plus the Ohio Republicans exposed as corrupt in just 2006 alone - though the Abramoff conspiracies are bigger than all that you've named. I could swamp your Democrats list some more just by invoking Ernie Fletcher's Kentucky conspiracy. And of course the Stevens corruption, also already connected to other Alaska Republicans, is just starting its own list.

    For real meaning, compare the nature of the crimes. The Democrats you mentioned stole a few $million, maybe, slashed some tires. I mean, come on - you've padded your list with a guy who took $500 for his anonymous single vote in a Democratic primary. You're comparing that to Attorney General Alberto Gonzales?
