  1. Re: no free lunches on New Solar Cell Harvests Hydrogen From Water · · Score: 1
    Let's investigate this math a little further.

    - Engine: 2.4L 166-hp inline-4
    - Outside dimensions: 172" x 72" (4.4m x 1.8m) So that's 122 kW (not half a megawatt) and 7.92 m^2 roof area. (It's probably more like 6 m^2 unless you can put panels on the windows)

    According to http://firstlook.3tiergroup.com/solar, Los Angeles averages 5.11 kWh/m^2/day in horizontal insolation.

    So, at a within-reach 20% efficiency, you get 6 * 5.11 * 20% = 6.1 kWh/day.

    The GM EV1 had either 18.7 or 26.4 kWh of storage, depending on configuration (http://en.wikipedia.org/wiki/General_Motors_EV1), with a range of about 150 km for the low-capacity batteries. Which makes for at least 8 km/kWh, in a car that could go 0-60 in 6.2s.

    So our all-solar commuter car could go 48.8 km/day. Enough for short commutes in sunny climates?

  2. Re:Rosen's view of copyright.. on Hilary Rosen Loves Creative Commons · · Score: 1

    Don't forget the most important piece of capitol a creative person can pass to his or her children-

    Creativity!

    Seriously though, intellectual capitol is an important factor in these new times. It is why a college education is so expensive! Don't underestimate the power of intelligence and education...

  4. x2vnc on Which VNC Software Is Best? · · Score: 1

    I can't believe nobody has mentioned x2vnc.

    It isn't like the other vnc's:

    1) run the vnc server on your windows box as usual.
    2) put your linux desktop next to it.
    3) run x2vnc on the linux desktop.
    4) move your mouse to an edge of the screen.
    5) Ta Da! x2vnc traps mouse and keyboard and sends it to the other box.
    6) Instant software KVM!

  5. Computer Baddie Etymology on New IM Worm On The Loose · · Score: 2, Informative

    Technically it is a virus and not a worm. Virii (physical and electronic) cannot spread by themselves; they need someone else to help them spread. Worms, on the other hand, can spread and multiply without anyone else's help.

    Since this virus requires human interaction, it is a virus and not a worm.

  6. Re:The publishers are adamantly against this on Google Launches Google Print · · Score: 5, Interesting

    prove to Amazon and themselves that it actually eats sales rather than driving them

    Actually, having books online for browsing increases sales. Just think about going to the book store and paging through a book before you buy it... You are much less likely to buy a book that is shrink-wrapped, because you have no idea of the quality of the book.

  7. Re:16x9 screen sucks for a computer on Review of PCV-W10 Desktop by Sony · · Score: 1

    I bought a Sony VAIO PCG-C1VE (PCG-C1VN in the states) a couple of years ago, and I would now advise people never to get a PC with a 16x9 form factor screen.
    Ahh, but it fits a terminal window very nicely, with room for winamp on the side. And the keyboard is Just big enough to type reasonably.
    As long as you have some other computer to do the real coding, this is quite a nice little machine.

  8. Deutsches Museum on Seeking Interesting Sites When Travelling the World? · · Score: 2, Informative

    In Munich, Germany

    This museum is HUUUUUUGE!

    It has all sorts of industrial and technological
    artifacts and exhibits, from a viking warship to a long hall of exhibits that mix two chemicals to demonstrate the reaction.

    I've heard it would take you a year to see the whole museum if you spent a minute at each exhibit. But I had fun just visiting it for one day :)

  9. Re:physics on Remote Feed: 72-Mile 802.11b Link · · Score: 1

    Actually,

    since most of the beam misses the dish, you could set up a listener BEHIND the dish and still sniff the signal.

    I think the NSA did this to sniff microwave links (which 2.4 GHz falls in to), even with satellites!

  10. How Fast? on Antimatter Space Drive · · Score: 2, Funny

    The article mentions that the speed of the antimatter/fission rocket will reach 260,000 mph in 4 months.

    That's .039% of c.

    I guess there's a lot of room at the top, too.

  11. Re:Fujitsu P2000 is very competitive on Sony Releases Smallest VAIO Yet · · Score: 1

    I've played back full-length DIVX (4) movies on my picturebook (667 MHz Crusoe). Looks really nice on the letterbox screen. The battery lasts longer than the movie, too!

    I'm sure the newer Crusoes can handle DIVX even better. Movie playback is a pretty repetitive task, so Code Morphing should work well.

    This is great for your own in-flight movie

  12. RP-TNC connectors on Connectors: A History of Their Technology? · · Score: 2, Interesting

    With the recent 802.11b Wifi craze I'm surprised anyone hasn't mentioned the RP-TNC connectors that appear at the back of the popular Linksys WAP11.

    They have proved very hard to find, and expensive to order. The connector or adapter cable often prove to be the most expensive part of a homebrew antenna!

    Does anyone have any antenna / RF cable tips or know of stores in the SF bay area?

  13. Samba browsing DAVE shares on Samba 2.2.0 Released · · Score: 1

    Has anyone gotten this to work?
    I always get "file not found" errors after using smbmount on a service shared from a Mac.
    Can any of the samba hackers here help me?

  14. Re:Nanotech background on Creating Nanotech Of The Nearly-Now · · Score: 1

    Probably the best background, is this article by Richard Feynman. It's definitely what got me interested in the field in the first place. Unfortunately nanotech is out of reach right now, we have to settle for things 1000x bigger (MEMS). TI's Digital Light Projector is pretty phat though.

  15. Why I don't Share on The Tragedy of the Digital Commons · · Score: 1

    I use gtk_gnutella to fufill my trance mp3 cravings. But I can't share anything because it isn't supported! Maybe that's why some people don't share - they can't.

  16. Another Benchmark needed on Tom's Hardware Linux NVidia Benchmarks · · Score: 3

    What about the "Time it takes to install" benchmark? New windows drivers are (usually) just a double-click away, while the XFree 4.0 installation is a nasty series of rpms, a kernel patch, and config file editing.

    I hate it when I can't surf slashdot because my X is broken!

    But it's worth it for the little quake icon on my gnome launcher.

  18. Silicon IS a precious stone on Optical Microchip Breakthrough In Canada? · · Score: 1

    After refining and a few lithography steps, an experimental silicon wafer is usually worth tens of thousands of dollars.

    And that's NOT including all the times the construction may have failed.

    So, when they do finally get a porous silicon wafer, it will indeed be a precious stone!

    Why don't they simply let the linux folks pound on it for a while and pick up the (open source) bug fixes?
    Otherwise people will just find the 'sploits on their own and, well, 'sploit them.
    Security behind compiled code just isn't security.

    No, really??? That's so small!

  22. SITN on Distance Learning Recommendations? · · Score: 2
    Stanford has a distance learning program called SITN. You can watch regular Stanford CS lectures on TV and even phone in questions. You submit your assignments either by mail or electronically. If you live in the Bay Area you can come to the university for exams.
