  1. Re:Energy storage is the issue on Funding For Automotive Fuel Cells Cut · · Score: 1

    There are a few places where hydrogen is an energy source. Some nuclear reactors produce hydrogen as by-product. Even so, the best idea would probably be to use it directly on site and enjoy the little extra output.

    Also, you could fetch hydrogen out of Jupiter's atmosphere. Getting there economically is left as an exercise to the reader.

  2. Re:You don't need to transport hydrogen. on Funding For Automotive Fuel Cells Cut · · Score: 1

    That same energy could instead be used to charge a battery. Lithium-ions are already close to 90% efficient, which no method of producing hydrogen can even approach. Combined with supercaps and high-voltage "fueling" stations, charge time would be a non-issue. So what does hydrogen get me?

  3. Re:Limited application? on Zotac's Ion-Based Mini-ITX Board For Atom Debuts · · Score: 1

    VGA is an analog signal, and HDMI is pure digital. DVI has different pins for both types. That makes HDMI -> DVI cheep, and VGA -> DVI cheep, but HDMI -> DVI -> VGA can't be done without an expensive D/A conversion.

    I'm imagining a Beowulf cluster of these. No, really, I am. I have a personal project that's going to eventually need a lot of parallel processing power. This thing has a dual core processor and comes with its own external power brick. They seem perfect for a cookie sheet Beowulf. Since they're aiming for retailing this for around $180, you can easily hit $200/per node once you add a stick of RAM. That looks cheaper than any other solution once you've added a power supply.

    Totally different issue. The problem here is inherent in all flash drives, but can be mitigated by clever controller design. AnandTech made an extensive report on this issue.

  9. Re:Plenty of Warheads to Reprocess on NASA Running Low On Fuel For Space Exploration · · Score: 1

    Pu-238 is used for these because it's an almost pure alpha emitter. Among other things, this makes it easy to design a foolproof casing in the event of a launch failure.

  10. Re:Need heat too, don't you? on NASA Running Low On Fuel For Space Exploration · · Score: 1

    Space is cold, but with no conduction or convection, it's hard to get rid of heat. The primary problem here is too much heat rather than a lack of it.

  11. Re:buy it from North Korea or Iran on NASA Running Low On Fuel For Space Exploration · · Score: 4, Funny

    What do you tell these people? How will they react? How will you govern them?

    It can work, as long as you think about these issues along with the rest of the invasion plan. Going in and just expecting to be greeted as liberators is criminally naive.

  12. Re:More context on Debian Switching From Glibc To Eglibc · · Score: 4, Insightful

    Looking elsewhere through the bug comments, it seems that there are assumptions in the glibc code that could break whenever the gcc people feel like it, even on x86. This was something that needed to be fixed, and isn't specific to x86 or any other non-embedded arch.

    Also, when has x86 ever been a "well designed architecture"?

  13. Re:uClibc on Debian Switching From Glibc To Eglibc · · Score: 2, Informative

    IIRC, uClibc can't run Apache. There's a place for uClibc, but that place isn't a generalized distribution like Debian.

  14. Re:I wonder... on US Trustee Asks To Send SCO Into Chapter 7 · · Score: 2, Interesting

    When were they ever a respected Unix vendor? SCO Unix never stood out from any of the dozen other Unix variants, and Caldera was the same way on the Linux side. All they had was some tenuous rights to the Unix name and code, but original Unix has been carved up so badly that it's impossible to know who really owns what.

  15. Re:Travesty? on Klingons Cut From Final Star Trek XI Movie · · Score: 4, Interesting

    The genetic alterations in question happened to adult Klingons, not newborns. Presumably, the cure later did the same.

    Incidentally, viral vectors can be used in real genetic engineering.

    I would have been satisfied leaving the whole thing as a retcon and pretending flat-foreheaded Klingons never existed, but the DS9 Tribbles episode was begging for it all to be answered. Tieing it into Kahn-like superhuman research and Data's family history was a surprisingly good idea for a frachise that didn't have Ron Moore to lean on anymore.

    Yes. A Private Little War is a direct reference to US-Soviet proxy wars. Both Klingons and Romulans fit the analogue in their own ways.

  18. Re:Travesty? on Klingons Cut From Final Star Trek XI Movie · · Score: 5, Informative

    It was explained away in the last season of Enterprise. A rouge human researcher in genetic engineering had made some superhumans, and Klingons wanted the tech, too. So they copied/stole the research and ended up implanting themselves with human DNA. The changes went viral, and soon affected the entire Klingon race. They presumably found a fix some time in between TOS and the first movie.

  19. Re:And.... on Senator Arlen Specter Becomes a Democrat · · Score: 2, Interesting

    He's hasn't been an automatic vote either way as it was. From a practical standpoint, nothing has changed. The big news here is that Specter thinks the Republicans are more likely to push a hard-right primary challenge (which they almost certainly go on to lose in the general election, given Specter's district) than Democrats are to push a hard-left challenge (which they might win).

    Seriously, I'd love to be able to read more info on this... without knowing all the evidence presented to get the warrant, it's a little silly to say that his use of multiple PCs and Linux was enough for the judge to have granted the warrant.

    It wasn't. Apparently, it was calling another student gay on a mailing list that did it. This is the sort of stupid that can only come out of Boston, Florida, Alaska, and Alabama.

    Also, I'd like to take this opportunity to inform everyone that CowboyNeal is a total homo, and I have several strange computers in my house where I could be hiding information.

  22. Re:Wait...what? on Star Trek Premiere Gets Standing Ovation, Surprise Showing In Austin · · Score: 2, Insightful

    There have never been that many hard SF movies made in any time period, and most of them are passed off as boring by whatever generation is growing up at the time. George Lucas didn't get famous for THX-1138, and Kubrick put audiences to sleep with 2001: A Space Odyssey.

    Further, there are no fewer kids reading now than there were 30 years ago. After public education took over, literacy rates went to all time historical highs, but it didn't last. Reading for fun was nearly killed off by TV, and the first TV generation grew up a long time ago.

    In short, people of every generation are dumb, and putting the blame just on the current one is silly.
