    "Pimple on the face of humanity."

    That's a rather delicate way of putting it. I confess to having a lower opinion.

  3. Too late on NIH Orders Halt To Embryonic Stem Cell Research · · Score: 3, Informative

    What if the scientists just charge for the research, but present an itemized bill that throws in the embryo destruction for free?

    The ruling applies to cell lines derived from more recent embryos -- they're already destroyed and would have been anyway, but the cell lines are already harvested. It's a strange ruling since it doesn't prevent any new embryo destruction (and wouldn't anyway, since they're excess IVF embryos and are headed for the biowaste system either way.)

    I'm mostly kidding, but isn't there some decent way to weasel around this?

    Nope. The Court has ruled. Unless and until a higher court reverses the ruling, it's binding.

  4. As always, not mentioned on NIH Orders Halt To Embryonic Stem Cell Research · · Score: 1
    Whether the order applies to the embryonic stem cell lines approved by the Bush Administration. Does this order "shut down embryonic stem cell research" including projects dating to long before the Obama executive order, or does it shut down some more recent stem cell projects using previously-unapproved cell lines?

    Hyperbolic headline department.

  7. It's the thought that counts on KDE 4.5 Released · · Score: 1

    Akonadi tries to solve real problems that users of KDE 4.4 (like me) currently experience.

    And this is aided by having your data in a fragile repository ... how?

    Try pulling the plug on your system. You don't have to be using KMail, it's OK if it's been sitting idle for hours. See what happens.

  8. Lots of new features on KDE 4.5 Released · · Score: -1, Redundant
    But it would be nice if they put more priority on robustness.

    Lately it seems that KDE is doing a Miguel de Icaza: devoted imitation of Microsoft. For instance, the "KDE Registry:" akonadi. Terribly fragile, but it's supposed to keep all of our data without a mechanism for backups.

  9. That's all nice on KDE 4.5 Released · · Score: 1, Troll
    but it would be even better if the robustness were more of a priority.

    KDE is doing a Miguel de Icaza lately and imitating Microsoft's "total integration," including their own version of the Registry: akonadi. Which may be nice, but it's also terribly fragile for something that's supposed to hold all of your data. See, for instance, bug 244250.

    Given that I'm vexingly ambivalent whether your username is icing on the irony, this level meta-irony at least is going way over my head ;)

    Actually, it's a reference to electronic signal integrity. Prior to getting fed up with /. moderators' habit of flagging "Troll" on anything remotely sarcastic and changing my sig line appropriately, it was "FR-4 is the root of all evil."

    Somehow I don't think that Toshiba is quite so stupid as to build what TFA describes: a laptop drive that wipes itself after the power is turned off.

    My bet is on the usual baked-in drive encryption, very badly described.

  15. Tell me on Rethinking Computer Design For an Optical World · · Score: 1

    So... uh... The 2nd Coming of FB-DIMMs?

    Without disclosing my Super Secret Identity, let's just say that I was there at the beginning of the FBDIMM fiasco, told my management to run, not walk, away from getting sucked into it, and proceeded to watch the train wreck from very close up. As in, on the field instead of front-row in the stands.

    I've made a lot of bad calls in my life but I totally nailed that one.

  16. There's slow and then there's slow on Rethinking Computer Design For an Optical World · · Score: 1

    Coax is 60-75% of light speed. Traces on FR4 board are around 50%. Inner traces on multilayer PC boards are below 30% of light speed. Interconnects on chip are sometimes even worse.

    Well, I'm not aware of anyone using epoxy glass for cable insulation. You can get pretty quick (0.8 C0 or so) with foamed Teflon insulation, but you have to be seriously wanting to pay for it. Easy to damage, too.

  17. Speed of whatever on Rethinking Computer Design For an Optical World · · Score: 4, Insightful

    I don't think that light travels that much more quickly than electrons do.

    Yes and no. In a vacuum, electrons aren't terribly useful unless you're driving them with a particle accelerator. In wires, electrons aren't really doing the work anyway: electrical signals effectively travel as waves in the dielectric surrounding the wires and in particular between signal pairs. In that case, the signal travels at around half the speed of light in a vacuum (faster if you use expensive insulation like Teflon, slower for other plastics.)

    Light in optical fiber is also slowed by the refraction coefficient of the material and by path-length extension in multimode fiber. However, on balance it's a bit faster.

    The real gotcha is that electrical signals at outrageous bandwidths suffer from some really horrible losses due to both skin effects on the wires and dielectric losses in the insulation. At 50 Gb/s and 30 cm, you're doing well to detect the resulting signal, never mind decode it. Worse, the losses are highly frequency-dependent, so you have to do all sorts of ugly things to pre- and post-condition the signal to make it usable. Some of this can be overcome by cranking up the transmit power, but then you get into that property of wires known as "antenna." All of that processing at both ends takes time, too.

    Just not worth doing, generally.

    Likewise, putting a bunch of streams out in parallel requires all sorts of cleverness to put the separate lanes together again after transmission skew. A single optical stream is much easier to use, sort of like the communications equivalent of Amdahl's Law.

  18. Here we go again on Rethinking Computer Design For an Optical World · · Score: 4, Informative
    This is eerily reminiscent of Intel's flirtation with Rambus: they were so focused on bandwidth that they sacrificed latency to get it. Yeah, the Pentium4 series racked up impressive GHz numbers but the actual performance lagged because the insanely deep Rambus-optimized pipeline stalled all the time waiting for the first byte of a cache miss to arrive.

    Same goes for optical interconnect to memory: the flood may be Biblical when it arrives, but while waiting for it to arrive the processor isn't doing anything useful.

    Now, peripherals are another matter. But if bandwidth were all it took, we'd be using 10 Gb/s PCI Express for memory right now.

  19. Writing the fine print on Oscilloscopes For Modern Engineers? · · Score: 1

    Except if you work on private projects using employer equipment they will probably end up owning your work.

    Unless you have a personally-negotiated employment agreement, they do anyway. It's not the equipment, it's your time -- which they're paying you for.

  20. After almost forty years in the business on Oscilloscopes For Modern Engineers? · · Score: 3, Insightful

    What would you, my esteemed Slashdot colleagues, get for yourself?

    An employer. Seriously. Every piece of test equipment I've ever owned (some costing upwards of $5000 1978 dollars) was a lousy investment.

    Especially when you consider that I have a lab at $WORK with scores of tools costing more than I make in a year, it's stupid to spend my own money on them.
