  1. Re:Not just the overall rate... on US Birthrate Plummets To Record Low · · Score: 1

  2. Not just the overall rate... on US Birthrate Plummets To Record Low · · Score: 3, Informative

    It's not just the overall birth rate, but also the break down of birth rate to various segments of population that matters.

    The linked article displays population projection from now to 2050, broken down by segments. It also shows the education levels of each segment. What it imply is we will end up with a less educated work force moving forward unless we are doing some heavy investing now.

    So, your $20 in 1969 may turn into $0 (albeit in 2050) unless we can somehow shore up "the kids these days".

    On the same day with the outages?

  5. Use a Mac on Ask Slashdot: Actual Best-in-Show For Free Anti Virus? · · Score: -1, Flamebait

    As we all know, Mac do not get viruses.

  6. Re:RAID on Ask Slashdot: Simple Way To Backup 24TB of Data Onto USB HDDs ? · · Score: 1

    An alternative to RAID is to get a Drobo unit (http://www.drobo.com/), fill it up with drives, and copy the data over, then remove the drives.

    The advantage is that the Drobo disk set can have dual-disk redundancy, just like RAID-6, and the drives contain enough meta data that you can insert them in any order. Just make sure you have the Drobo unit in hand to read them out.

    I have not had great experiences with the enterprise model (B1200i) but the consumer models (4- or 5-bay) seem to work great.

  7. Re:The Water Cycle on For Much of the World, Demand For Water Outstrips Supply · · Score: 1

    A lot of places (where water is more scarce, obviously, or where people plan for such things) have laws that encourage capturing rain water, instead of simply flush them down storm drains and out to seas:

  8. Re:clock skew? on High-Performance Monolithic Graphene Transistors Created · · Score: 1

    That sounds great, but at those speeds the distance traveled per tick gets *much* smaller. I see a challenge in trying to propogate(sp?) a clock signal across the chip to have things work in concert with each other. I'm more a software guy than HW so I may be missing something obvious? ISTR an article here about a year or two ago about clockless logic. Would we need something like that in order to make a modern CPU out of this tech?

    tl;dr How do you keep the clock from getting skewed up?

    As some point, they will probably use asynchronous signalling. Otherwise, probably 99.99% of the power consumption will be in the clock circuits.

    I believe Sun was going to have some async units in their Sparc processors. Not sure what happens to them.

  9. Re:Obligatory question on South Korea Surrenders To Creationist Demands On Evolution Textbooks · · Score: 4, Insightful

    Observational science doesn't disprove ideas about origins. Those ideas can't be tested scientifically. All that can be done really is to interpret the data in the context of your preferred presuppositional research framework. That's what materialistic scientists do... that's what scientists who believe in a young universe do.

    Again, this is wrong. The "Young Universe" so-called theory can easily be tested scientifically, and every bit of data says that it's false. In fact, it is for that reason it should not even be called a theory since theories are supposed to have the benefit of empirical data to back them up.

    Not when the answer you get is "that is how everything is created, to give you the illusion that evolution took/is taking place."

    When a person looks at a problem with a predetermined solution, evidences can simply be twisted to fit that solution.

    Once you believe that there is an omnipotent being who creates everything, it's not a stretch to makes everything around you fit into his/her/its whims.

  10. HTML5 convergence on Mono Abandons Open Source Silverlight · · Score: 4, Insightful

    This is just another sign of the industry converging to HTML5 as the primary display API. Flash is going away, now Silverlight is, too. Hopefully the companies will increase their efforts to allow users / developers to migrate existing applications to the new API.

  11. Probably copyrighted on HP's Core WebOS Enyo Team Going To Google · · Score: 1

    The problem with that is, most of those features that make WebOS easy to use are probably copyrighted. Then again, with HP opensource WebOS, Google might just be able to incorporate it wholesale into Android.

    TFA: "... But diesel engines are dirty and require expensive exhaust-treatment technology to meet emissions regulations."

  13. Re:The future will be printed, not forged. on An 8,000 Ton Giant Made the Jet Age Possible · · Score: 1

    Actually, I remember reading something in NewScientist (??) about global consolidation, where all the (specialized) nuts and bolts in the world are made by just one or two factories, and there are no redundancies in a lot of sectors anymore because it is cheaper to consolidate specialized manufacturing into one location.

    I just hope those locations are disaster proof.

    Maybe the newer versions of the calendar are better and more accurate? Older isn't always better, you know.

  17. Re:Counting? on Study Suggests the Number-Line Concept Is Not Intuitive · · Score: 1

    Actually, the "counting" concept is built on top of sets.

    This article about set is pretty good: http://www.newscientist.com/article/mg21128231.400-ultimate-logic-to-infinity-and-beyond.html, so is this: http://en.wikipedia.org/wiki/Counting

    So, does the question become, is "set" innate?

    Yes! Then you can play racing games while driving to work! Using Google Maps layers for tracks! Better yet, you can race against your coworkers to see who will get to work first. Productivity will soar!

  22. Misleading title on GNU/Linux Running On An 8-Bit Processor · · Score: 1

    What was done (from the summary) was to run an ARMv5 (32-bit) emulator on the 8-bit processor. Then run Ubuntu on the emulator. Not to take anything away from the accomplishment, but that is not the same as porting / running Ubuntu on the same processor.

  23. Re:Does the display require power? on LG Begins Mass Production of First Flexible E-ink Displays · · Score: 2

    You still need electronics to flip / reset the eInk pixels. Maybe that's what the Thin-Film-Transistors are for. But that's pure speculation on my part. If that's the case, once the pixels are set, you no longer need power to keep the displayed image.

    With LTFS making data compatible between different vendors' hardware, we can now hope for cheaper, non-branded drives. I'm hoping in a few years I'll be able to afford my own Grandfather-father-son backup scheme for data at home.
