  1. Re:Grand Central Dispatch on Intel Details Upcoming Gulftown Six-Core Processor · · Score: 1

    GCD is a nice library with an elegant API. Unfortunately it is not portable, because it requires a compiler which supports a non-standard extension to the C language.

  2. Battery powered aircraft on NASA Designs All-Electric Personal Flight Vehicle · · Score: 2, Informative

    The Antares 20E made its maiden flight in 2003. It is a self-launching glider with battery powered engine:

    A wonderful glider. Sad it's so expensive (several 100k euros).

  3. Re:It "weighs" two tons? on The Top 5 Technology Panics of 2009 · · Score: 1

    How ironic. You too fail to understand basic physics, because you don't seem to know that tons is not a unit of weight (neither does the editor/submitter).

  4. Yes on Malware Found Hidden In Screensaver On Gnome-Look · · Score: 1

    The reference policy has a module for xscreensaver, and it's very tight - it doesn't allow network access.

  5. Re:Electricity Hydrogen on Sahimo Hydrogen Vehicle Gets Over 1,300 mpg · · Score: 2, Informative

    That's the general problem when you concentrate a lot of energy in little space. There are practical differences between fossil fuel, hydrogen, urane and batteries, but the concept of accidentally releasing (converting to pressure/temperature) much of this energy is pretty much the same.

  7. Memory usage on GNU Coughs Up Emacs 22 After Six Year Wait · · Score: 1

    The gtk version uses twice as much memory as the standard X version of emacs22. WTF?

    Comparing emacs21 and emacs22 (no gtk), the new version uses maybe 10% more memory.

  8. Re:Why binaries? on Performance Tuning Subversion · · Score: 1

    Storing JAR files in SVN is wrong most of the time. Either the JAR file is built from the sources in this same repository, and build results should really not be stored in SVN. Or it is required to build the software - then it should be part of the local computer's software installation, and your ~/build.properties should point to the exact location.

  9. Can you hear television? on Driving Away Teens With High Frequency Noise · · Score: 1

    I mean, when the sound is muted. When asking my friends (teenagers and up to 30), only very few can. I can (age 26), though I suffer from Tinnitus. At child's age I could hear when my sister secretly watched TV in the other room, doors closed, sound too silent to hear... Interestingly, I can also hear when you switch channels and what the quality of the picture is, and what kind of interferences there might be (diagonal stripes, snowy picture, ...)... btw. I don't own a TV. Not only because I find the noise annoying, but also because it's boring...

    last week, I formatted my new USB hard drive with reiser4. It works well with both 32 and 64 bit (kernel and userspace), no problems so far.

  13. gyrocopter on Carter Copter Breaks Mu-1 Barrier · · Score: 1

    Page is down for me, but for those curious there are more funny things you won't believe they can fly (German text, but some pics). I saw one of these 2 weeks ago, looks _very_ strange how they fly. The top rotor is not driven by an engine, only the rotor on the rear. The top rotor is then rotated by the wind, giving lift to the aircraft.

  14. Re:Pedant on GCC 4.0.0 Released · · Score: 1

    C sources are text files. Text files consist of text lines, terminated with a newline character. The last line is also a line, which should be terminated with a newline character (see above).

    How can you say "it just doesn't compile anymore" when you're talking about a *warning* message, not an *error* message?

  18. Re:Painter,yes. Pilot, no. on What You'll Wish You'd Known · · Score: 1

    wrong. the article is only partially wrong.

    a glider moves relatively to the air surrounding it. if you turn into the wind, your speed does not change, relative to the air (wind). You get exactly the same ascending force, and the same vertical speed.

    But due to the air moving relatively to the ground, you get a lower speed over ground. That makes you move slower, thus requiring more altitude for the same distance. Remember, that's not because the vertical speed increased, but the horizontal speed decreased.

    people often mistake vertical wind for horizontal wind. TFA author even mixes them in one single sentence.

  22. Re:Too late? on X-Plane Demo Released for Linux · · Score: 3, Informative

    flightgear is a nice project, but it can't bear comparison with X-Plane, by far. X-Plane has its focus on a physically exact simulation of aerodynamics. when you design a new plane in "normal" flight simulators, you have to design both the visuals and give many many hints about its behaviour. in X-Plane, you define the shape, and X-Plane calculates the rest. I was surprised how exactly it simulates the gliders I have already piloted in RealLife(TM) (I'm glider pilot for 11 years now - glider pilots are the ones who really know how the plane works, because they need to)

    X-Plane is the only good flight simulator I know of. MS FlightSim is good to train radio navigation (it used to focus mainly on navigation before it became "mainstream"), but it gives you a really bad idea of the behaviour of the simulated planes. flightgear isn't better. Flight Unlimited (about ten years ago) used to be one of the best, and there is the German "Segelflug-Simulator", but neither have the simulation quality of X-Plane.

    I am really happy they've done the Linux port, torrenting at 40 kB/s currently :]

  23. LCD vs CRT.. on Are LCD Displays Ready For Gaming? · · Score: 1

    I own a Iiyama 21" TFT (1600x1200). I love it when working on code. Ok, it's not an ultra-low-latency display...

    But when I play Enemy Territory, I put it away and connect my old CTX 19" CRT. I set it to 77 Hz and configure a maximum frame rate of 77 in ET. Every frame of the game is on my CRT nearly instantly, 1:1. No buffers, no DAC/ADC troubles, no refresh rate interferences etc.

    My score is always better when I use the CRT. Aiming is so much harder on my TFT. It _is_ noticable.

  24. As a glider pilot.... on Zero Gravity Flights for the Rest of Us · · Score: 2, Interesting

    in a glider, you can fly in zero-gravity for about 5 or 10 seconds. If you like the idea, go to the nearest airfield and ask them, it's fun. Price should be around 30 dollars for a flight for non-members. But you can't run around at zero gravity, because you'll be wearing a 4 or 5-point seat belt. (pssst... glider acrobatics are even more fun, but that varies between -2g and +5g)
