Slashback: Brainwaves, MPnothin', Telescopy

Slashback tonight with a few words on forcing Open software, NASA mind-reading tricks, a reminder of one nice way not to pay for an MP3 decoder, and more. Read on for the details. Update: 08/28 00:36 GMT by T : Oops -- No DoubleClick news tonight, as the original headline implied. Regrets.

They felt your unvoiced contempt. perl-guy writes "According to a recent NASA press release, reports such as those in this Slashdot story stating that NASA is planning to develop mind-reading equipment for airports in efforts against terrorism are exaggerated and ignore the facts and science behind current research. 'NASA does not have the capability to read minds, nor are we suggesting that would be done,' said Robert Pearce, Director, NASA's Strategy and Analysis Division in the Office of Aerospace Technology in Washington. 'Our scientists were asked to think outside the box with regards to ideas that could aid the nation in the war on terrorism and that's what they are doing. We have not approved any research in this area and because of the sensitivity of such research, we will seek independent review before we do.'"

Let's put that Schneier fellow on the "body-search" list. Quixotic1 writes "Four articles are highlighted over at The Atlantic Online arguing that to protect ourselves against terrorism we must rely on people, not simply on technology. The outline touches on the recent article about Bruce Schneier, the national ID card proposal, and the Clipper Chip."

Star systems, slip through fingers, etc. Since Thomson Multimedia / the Frauenhofer Institute has decided to press the $0.75-per-decoder charge for MP3 decoders mentioned earlier today, there are probably a lot of people suddenly more interested in other formats. I favor the Xiph Foundation's Ogg Vorbis; Xiph CEO Emmett Plant has written his thank-you note to Thomson Multimedia.

Depends what you consider "great." morhoj writes "ZDNet is running a great commentary that talks about the recent debate involving the Digital Software Security Act (the California law the would force governments to use open source software). ''Open source is supposed to be about freedom. Unfortunately, certain advocates have lost sight of that goal.'' I couldn't have summed it up better myself. Forcing anyone to use Open Source software is no better than ludicrous Microsoft licensing agreements." I think Carroll is dead-wrong when he focuses on cost-benefit analyses (and ignores the question of whose money is being spent by whom, for what), but YMMV.

I bet they'd have to edit Super Troopers, too. David_Bloom writes: "Following up on an earlier article, according to a page (link is a direct link to a frame - context sold separately) on the IMAX website, the first movie to use 35mm to 70mm IMAX DMR technology will be the hit 1995 flick Apollo 13. It is interesting to note that, according to a FilmRatings.com lookup, the film has been edited for content for its IMAX release (which is bad news for people hoping to see The Matrix or similar movies on IMAX)."

No, I said I'm meet you by the other telescope! Reader Dan Yocum points out that the skyward-gazing Yalies who captured asteroid 2002 NY40 digitally did so with a different telescope than the one reported. He writes: "They weren't even using WIYN. They were using the 0.9M that's next to it (about 50yd away)." Thanks for the correction!

      Anyone who uses this code in its product.

      It's not the Frauenhofer code which requires a license, it's the format itself. If your product can use, play, encode in MP3, you gotta pay.

  2. 70mm wide, yes. by Bingo+Foo · · Score: 4, Informative
    2001: A Space Odyssey [...] it's already in 70mm

    It's already 70mm wide. IMAX rolls the film "sideways," so the short dimension of the visible frame is the width of the film, and the long dimension of the frame is along the direction of the roll. Any standard 70mm film would have to be retransferred to the IMAX 70mm sideways format.

      Actually, it's a little different even from that. 2001: A Space Odyssey was filmed on 65 mm film negative using the Super Panavision 70 process. Super Panavision 70, like CinemaScope and other formats, used an anamorphic lens to distort the image on the negative. If you look at a frame of the original camera negative-- good luck getting FotoKem to get it out of their vault for you-- you'll see a picture that seems too tall. You correct for that distortion by using a complementary lens, either when you project a print of the film, or when you transfer the negative to make a print. 2001 was printed in 35mm anamorphic (which used a cylindrical lens to restore the image during projection), 70mm anamorphic, and 70mm flat. Depending on which print you look at, the images are going to be pretty significantly different.

      So it's not completely true to say that 2001 was 70mm wide. The dimensions of the actual film image and the dimensions at which it's projected have a complicated relationship.

  3. Ogg comparison page by ivan256 · · Score: 2, Informative

    I've never seriously listened to the difference between Ogg Vorbis and the other codecs. I followed the link in that letter to the Ogg comparison page, and down at the bottom there were samples made by Microsoft for Media Player 8, and Real, and an Ogg version of the same piece. If you play the 64kbit ogg file, and the 64kbit wma file, you hear a *major* difference. The harpsichord is completely missing from the windows media version! Usually when there is a comparison like that the difference is subtile, and you really can't tell with crappy equipment. I certainly wasn't expecting such a vast difference in quality.

    I'm impressed.

    Nope. The story was right the first time. It refered to the "WIYN 0.9m". The WIYN consortium (of which Yale is a member) recently took over the 0.9m (which had previously been operated by NOAO). As a result, one now needs to differentiate between the WIYN 3.5m and the WIYN 0.9m.

    To be fair, when one says just "WIYN", one is usually refering to the 3.5m, but the original story clearly states "WIYN 0.9m."

    The diffrence is Peru was pushing for "Free Software"(read open standards), whereas CA is pushing for "Free Software"(read RMS). The first is the correct action, the second is just as shady as mandating that MS be the only software used by gvt.
