  1. based on "aloha" radio network in Hawaii on Leonard Kleinrock On The Origins of Packet Switching · · Score: 2

    That is what Metcafe says.

  2. Really "April 1" on Microsoft Stops New Work To Fix Bugs · · Score: 2

    Thats the only way a pronouncement like this makes sense :-)

  3. anti-plagiarism software and copyright on New Scientist Tries Out Copyleft · · Score: 2

    "What the net giveth the net taketh away"

    The recent scandal by several historians shows that it becomes increasingly difficult to steal someone else's work and claim it as your own. The net makes it easy to find and copy other people's work. At the same time improved search engines make it easier to detect that this has happened.

    What this doesn't address is money. Though it is easier to maintain authorship priority on the net, it doesn't prevent people from making free copies.

  4. Moon lacks hydrogen on Billions of Habitable Planets? · · Score: 2

    Most of life and our civilization burns hydrogen compounds for energy. This is water or hydrocarbons. The moon appears to outgassed most of its water and hydrocarbons eons ago. Might be a bit ice in some the perpetually dark polar craters- but not a whole lot. We'd need to import hydrogen from earth or a capture a comet. Comets have lots of water and hydrocarbons.

  5. this is Asimov's universe on Billions of Habitable Planets? · · Score: 2, Informative

    Asimov has many life-capable planets out there in this Foundation universe (and several other stories). However, none have developed intelligent life. 90% of earths history was like
    that. You'd just see deserts and a little bit of scum in the water. Worms and such developed in the last 12% of the earth's age. Fishes and plants in the final 6%.

  6. takes six months on Speed of Light Measurement Using Ping · · Score: 2

    You look for timing discrepencies when Jupiter is closest to the earth and furthest from the earth (about six months apart). The moons will appear to be slow or fast about fifteen minutes, or the light time to cross earth's orbital diameter.

  7. Use "MPEG": people differ by 0.1% on The Amazing $5k Terabyte Array · · Score: 2, Interesting

    At the most people's genomes differ by 0.1% from each other - much less than that if you are relatives. Therefore you'd record the differences, sort of like several of mpeg algorithms.

  8. thousand hours of video? on The Amazing $5k Terabyte Array · · Score: 3, Interesting

    Video is the most bulky storage people would save. How much would people want to save for re-viewing? First you have the time-shifting stuff like TiVo/Replay- perhaps a few tens of hours at most. Then you would be your favorite movies and TV series. As video-phone improves you might be saving some hours of friends and relatives video conversations. With infinite storage, the constraint becomes need and time to view all that stuff. And you'll probably be wanting to spend your time looking at new stuff. So I'd guess most people's real needs would be hundreds to a thousand hours. At 1-2 BG per hour, your talking about a terabyte or two.

    I don't include the argument that you'd have trouble finding old stuff. Computer software is more clever at organizing things - far better than material storage. A good recent example of this is Apple's "iPhoto" that much more convenient for organizing thousands of photos than physical albums.

  9. public lacks imagination of expert on Public Survey For NASA's Planetary Research Priorities · · Score: 2

    I agree public feedback should be solicited for NASA decisions. But they lack the technical depth and imagination to convince what can be done and be done next. For example, the recently approved Kepler satellite will look for extra-solar planets by continuously gathering light from the same area of space for five years. It uses a 350 megapixel CCD array. John Q would not imagine this

  10. new customer interface on Online Retailing Comes of Age · · Score: 2

    Amazon provided a new customer interface- one the catalog companies and Walmarts don't get yet. OK, everyone has a catalog on line now. Amazon was the first to do this for books. Amazon has custom ads, based on a customer's buying and surfing habits. Amazon distills its sales patterns - what subgroups are buying, best-seller lists.

    I do agree that perhaps they should not have gotten so much into the "bricks" and built warehouses, etc.

  11. Computer science roots in Beautiful Mind on A Beautiful Mind · · Score: 4, Informative

    I'm about half way through the book.
    Von Neuman plays a role in the book.
    Von Neuman invented the min-max algorithm which
    is widely used in artificial intelligence game
    playing programs such as chess. Nash's equilibrium
    point is supposed to be a powerful generalisation
    on min-max, but I don't see it often used in A.I. programs.
    Also in the book Von Neuman flips off Nash as being a pompous grad student.
    Nash gets the final laugh when he WINS the Nobel prize
    and Von Neuman doesn't.

    The founders of Artificial Intelligence John McCarthy and Marvin Minsky
    were classmates of Nash and have cameos in the book.

    Later in his career Nash becomes something of
    a computer hacker, but I haven't reached that part of
    the book yet.

    Both the book and movie are rare lterary depictions of grad school life.
    They capture the stresses of science/engineering nerds.
    Also things have changed since the 1950s and now,
    but not as much as you'd think.

  12. MS security = oxymoron on Security Community Reacts to Microsoft Announcement · · Score: 0, Flamebait

    oxymoron: (def) A two word phrase in which the meaning of the first word contraditions the meaning of the second word.

  13. "Strong Delete" function on Document Retention - How Long is Too Long? · · Score: 2

    Most OS deletes just delink the disk storage from the used-list, but don't erase it. A "strong delete" would write zeros in that storage. Technically you need to write random patterns several times in the old storage to truely erase it.

  14. Smart Dust on Nano-sized Microchips? HP Says So. · · Score: 2

    Berkeley profs were working on very small computer systems that could be used as environmental or medical sensors (or weapons). They can sense, compute, and communicate.

  15. sperm + egg? on Ultimate Stem Cell Discovered · · Score: 2

    This fits this criterion!

  16. fuel cells, electric vehicles ... on News Media Scammed by 'Free Energy' Hoax · · Score: 2

    Slashdot often posts articles about these "new energy" devices. However, their energy has to come from somewhere else, typically a dirty "old energy" source.

  17. satellite media labs in UK, India, Japan on MIT Media Lab Tightens Its Belt · · Score: 2

    The Media Lab was in a mega-expansion mode. First it is building a second building on the MIT campus. Second it is planning up to three branches abroad. These branches are quasi-independent of MIT. They are more like dot.com incubators. They get their funding entirely from industry and foreign governments. They do not have professor slots or degree granting rights. However, MIT profs and tudents may spend some time in the branches.

  18. most sought-after work site on campus on MIT Media Lab Tightens Its Belt · · Score: 2

    Many MIT students would PAY to work in the media lab. Their families are already paying $35K to attend MIT. Computer science is the most popular MIT major, choosen by 40% of the unergrads. Computer science labs are the most sought after positions for pleasure or student-aid jobs. And the playful media lab is the most popular of the computer labs.

  19. undergraduate pay is prevailing minimum wage on MIT Media Lab Tightens Its Belt · · Score: 2

    First, MIT sets the general wage guidelines for undergraduate work-study. Its not all that much higher than prevailing minimum wage of the area, which used to have a tight labor market until the tech crash. Harvard insituted a "living wage" after years of protest for its immigrant janitors of $10.50 an hour.

    Since student's families are paying around $35K a year to go to MIT, hey are paying about $20 / hour (based on MITs own calculation of a 45-hour study week) for the privilege of going to MIT. To get some back, is another privelege.

    Greedy vulture capitalists distracted the contruction of internet commerce in the late 1990s. Finally a few companies are getting it to work properly.

  23. ClosedBSD on Custom OpenBSD 3.0 with IPFilter From Darren Reed · · Score: 1, Redundant

    Not such animal as "own" release of "Open"BSD.
    The two terms are incompatible.

  24. great book, but no conclusion on Browsing Alone · · Score: 5, Informative

    I've personally noticed this trend- that many
    organizations filled with boomers seem to be
    getting grayer as the younger generations
    dont participate. These include professional
    societies, hiking & running clubs, etc.
    Then too, boomers boycotted the organizations
    of their parents- chambers of commerce, church
    socials, etc. This book notes in the last 50
    years, each generation has been doing less
    compared to the previous. The book suggests
    about a dozen causes, but none really clinches
    it. Nor do the sum of of clauses explain things.
    The trend of less civic participation began long
    before the InterNet became popular, so I wouldn't
    blame the net.

  25. programmers per computer declining? on The Brave New World of Work · · Score: 4, Insightful

    The mainframe computers throught 1960s had ten or more programmers per computer. 1970s minicomputers require a couple. Then came the personal computer and the mass software industry. There are now 100 million personal computers (home and business) now in the US at least, plus ten billion embedded computers in cars, appliances, traffic lights, etc. Maybe a million programmers now at the most. So we've seen a steady a drop of programmers per computer from 10 to .0001 in the past 40 years, a factor of 100,000 or a bit slower than moores law.
