  1. Re:about time... on NASA Probe Blasts 461 Gigabytes of Moon Data Daily · · Score: 1

    I'd like to see a REAL color photograph at some point and not something they recolored after...
    and real video footage as opposed to footage put together from still images

    There's no such thing as "real color photography" actually. Any color camera only approximates the color you see with your eyes, even old film cameras. Pick up any decent book and photography and you'll see mention of using filters to make things look more natural. With CCD cameras you're only counting photons. The detector itself can't tell a red photon from a blue photon, and it relies on an arrangement of band pass filters so that individual cells collect only a certain color range. So your point and shoot color CCD camera is like multiple black & white cameras with different color filters. The Wide Angle Camera (WAC) on LRO has 5 visual band filters and 2 ultraviolet band filters. They bands can be put together to give a "color" image. Even when you look at one of these color images you'll still see the gray Moon, so it's not very exciting visually. However, the response at different frequencies is very useful to scientists in determining properties of the imaged area.

    As for video footage... egads! Nevermind that "real video" actually IS a series of still images, we have a firehose of data to deal with right now!

  2. djb has an alternative? on DNSSEC Advances in gTLDs; Bernstein Intros DNSCurve · · Score: 4, Funny

    go figure...

    Perhaps he should start his own separate Internet and be done with it. ;-)

  3. Re:What happened to the Indian & Japanese spac on NASA Shakes, Bakes, and Rattles Lunar Spaceship · · Score: 1

    Info on the Indian spacecraft can be found at http://www.chandrayaan-i.com/

    As for the attention LRO is getting... well good! The various instruments on this orbiter will provide massive amounts of data, useful in several fields of science. It's also an important step for the planned presence on the moon.

  4. Be honest on Should the Linux Desktop Be "Pure?" · · Score: 0, Flamebait

    I've noticed a lot of Linux people talking about Freedom in software while running proprietary stuff. This is pure B.S. Do what you feel is right and what works for you, but don't lie to yourself and others. If you're going to accept BLOBs and other proprietary software that's fine, but quit talking about how Linux is opening everything up. If you're going to talk about Freedom, then quit using all the closed source stuff and live by your words.

  5. Re:Closed :( on nVidia Preview 'Tegra' MID Platform · · Score: 1

    Too bad this comes from nVidia, who is hostile to open source. Who gives a shit? (2) If you want to run the operating system and software of your own choice then YOU should. If you're happy with what's bundled and you don't care otherwise then that's fine for you, but it's not good enough for me.
  6. Closed :( on nVidia Preview 'Tegra' MID Platform · · Score: 0, Troll

    Too bad this comes from nVidia, who is hostile to open source. If it were someone else we might at least hope to get specs. Oh, well...

  7. Re:Why bother? on Chroot in OpenSSH · · Score: 5, Insightful

    Understanding the issues is better than parroting what you've heard from random sources. Given the OpenBSD and OpenSSH track record for security it's obvious they have some serious clues about security.
