  1. 3D scrabble on Scrabulous Returns To Facebook, As Wordscraper · · Score: 1

    2D is 15^2 with 100 tiles (55.5% empty).

    Perhaps 3D is 15^3 with 1000 tiles (66.6% empty) with same letter frequencies, but ten'ed. Or should we make it 1500 tiles, so the same empty fraction is preserved?

    It would take ten (or 15) times longer to play since the words themselves don't change. Or maybe I'd shrink the overall palying cube to 10^3 or 12^3 to keep playing time more reasonable.

    The bottle neck is adequate visualisation. I'd like a convex holograph with high transparency. If you selected any edge in any of the three coordinates, it would nighlight that playing surface. And maybe you'd want a pipe view too: Each letter is really a six-sided cube with the same letter on it. They would grow out of each other like branches on a tree.

  2. the oven was the clinching experiment on NASA Announces Water Found On Mars · · Score: 1

    They previously found something shiny, white, and hard. Small scrapings disappear after a few days by sublimination (solid evaportation). When a chunk of icy soil was put into an oven, then slowy heated, the thermometer got stuck at 0 degrees Celius for a while. This a science experiment done in junior high: heat a block of ice with a thermometer in it. The temperature rises until 0 degrees and stalls there until the ice is completely melted before rising again. Solid water has this phase change at this temperature.

  3. hexagonal scrabble? on Scrabulous Returns To Facebook, As Wordscraper · · Score: 4, Interesting

    I googled this and saw at least five different software versions. I presume you could also play on a 3D tesselation, should you be able design a convenient user-interface. (I guess it wounld start to look like sparse building girders.) I wonder if Hasbro has gone after any of these.

  4. paid to eat peanut butter for two months on NASA "Bed Rest" Contractor Blogs the Days · · Score: 1

    At our college there were studies where students were paid to eat a completely controlled diet for two months. These were experiments to what happened if you completely eliminated one component from the diet, like an amino acid. The food was tubs of flavored paste, much like penaut butter. I'd people would go mad after a few weeks. I wonder how they prevented cheating.

  5. No real "market" for such devices on Workings of Ancient Calculating Device Deciphered · · Score: 1

    Maybe a rich nobelman or bishop might sponsor a craftsman to make such exquisite devices, but there werent hat many potential customers. Modern clockworks got off the ground because churches and monastaries wanted more reliable ways of scheduling group prayer and there were a lot these in late medieval times. Then busnessmen and up-and-coming-types want one too, and you'v got a good market then.

    Similar issue in China. Crasftsman made some nifty things for the emporeror, but few others to sell it to.

    If its true, I doubt a privacy lawsuit could establish either. But a youtube incites a nutty neighbor to take some viglante punishment action, then they may have a case. This has been an issue with some US sex-offender lists where some people have been killed.

  10. watching nightly SpaceStation passes gives me hope on NASA Turns 50 · · Score: 1

    I'm disappointed the US Space Program didnt meet the expectations of 2001-Space Odyssey which came out when I was kid (and a year before the first moonwalk). Yet I still have hope of a space future for mankind. Even though the ISS is a grossly over-spent $100 billion, seeing it pass overhead several times a month gives hope of a space future. Its the tenuous presence of humans in Space. My friends dont understand why I watch the ISS. Am I crazy? And I dont care whether its the US, Russia, Europe, China or a kid in his garage who succeeds, just that someone does.

  11. Google = SkyNet on Are We Searching Google, Or Is Google Searching Us? · · Score: 1

    The only reason SkyNet isnt called Google because the original Ellison short story was written 30 years before Google was founded and the Terminator movies ten years before. The authors made up another name.

  12. we middle age people worry about this on Drug Halts Decline In Alzheimer's Patients · · Score: 1

    Its called "senior moment jokes". Many of us no longer have the photographic memories of a high school or college students. I could pretty much breeze through classes then or memorize technical manuals upon first read-thru. However, its not long term memory that goes first in Alzheimers, but short term memory. Like did you remember turn off the car lights, close the garage door etc.? One remedy is to develop rituals, e.g. morning wakeup routine, to make sure you've done everything. But surprises like a cat running across the driveway or a cellphone call can break your train of thought.

    So does this apply to computer programming? When you are coding you need to keep several ideas in short term memory at time. With Alzheimers, I suspect that ability would go away. I use legal pads more to write down fleeting thoughts like a new feature or minor bug you want to return to in the future. Else you remember you are supposed to remember something, but forgot what it was :-) Computer programming itself might be a partial antidote against Alzheimers since you are constantly exercising your memory. The old cliche: use it, or lose it.

    I've been watching some of these ads from Ciruit City, Best Buy, etc. These Taiwan laptops are becoming very price competitive. Not as cool as a MacBook.

    So I've heard. Instead of mechanical feedback, computers can adjust values, etc. more precisely.

  15. 30 years after an MIT degree on Ivy League Computer Science Curricula Exposed · · Score: 2, Insightful

    (We'll argue whether MIT is ivy somewhere else.) Most of the specific-knowledge courses like OS-360, PL/I, APL, LISP are in the dustbin of history. The general knowledge courses in algorithms, digital electronics, mathematics are still relevant and haven't changed a whole lot in three decades, although new software engineering techniques continue to be added.

    That cache of "ivy" helps you stay in the job market, even long after many software engineers in our fifies are long put out pasture. Ironically many of the classmates I've kept in touch with switched to software after majors as diverse and geology, biology and music.

    The latest results of Messenger's first flyby of Mercury confirms a magnetic field and molten outer core. Conversely, Venus which is Earth's twin in size, seems a lot more dead. A more important factor may have been chemical composition at the time of formation - Mercury had more metal. Elements may have been unevenly distributed as function of distance from the Sun in the original planetary nebula.
