  1. Edges, textures and sound on Converting Images Into Sounds for the Blind · · Score: 2, Interesting

    Sound might be a very important way to convey images, either an additional one to textures, or replacing the textures completely. It may instantly inform about the kind of a surface. Sound might also convey edges, but then there is a problem of detecting edges: it is usually easy if the map is in a vector form, but in the case of general raster images a good edge detector or even a human that would mark the edges might be needed.
    Partly offtopic: a free software to convert images to tactile graphics using edge detection and textures: JTactileGraphics. It does not have sound support currently, but one is being added.

  2. Re:How is it free or open source? on Ciphire, A Transparent, Easy PGP Alternative · · Score: 1

    my comment here, I had put it in another branch by mistake. BTW, I do not criticize that software, even that I would rather use some standard with available open source implementations, I just meant that the story uses misleading terms.

  3. Re:How is it free or open source? on Ciphire, A Transparent, Easy PGP Alternative · · Score: 1

    This is exactly tha page with that citation. Your comment seems to be disinformative in a way similar to that of the story text. Perhaps you'd need to read the Open Source Definition.

  4. How is it free or open source? on Ciphire, A Transparent, Easy PGP Alternative · · Score: 5, Informative

    From their pages: "Ciphire Mail will always be free for private users, non-profit organizations, educational institutions, and the press".

  5. DISR description on Titan Photos and Sounds · · Score: 1

    Thanks. I also have just found a great page about the probe instrument: DISR.

  6. Perhaps because of the relatively low light on Titan Photos and Sounds · · Score: 1

    Ah, it might be that there was very dark - it is about one light out long to Sun and there is a thick haze. I forgot about that.

  7. Resolution lower than Venera 14's? on Titan Photos and Sounds · · Score: 4, Insightful

    It is amazing that the whole multi-stage - three parachutes amongst other - landing was a success and the images are very interesting, but why the images seem to be ever more blurry than these of the Venera 14 from 1982?

  8. Re:Not only for streams on Peercasting Ready for Primetime? · · Score: 1

    I meant that sharing bandwidth by a community might be good not only for streams, but also for some types of internet sites. The methods might have to be much more complex than in the case of a single stream, for example only xml/images would be exchanged by the peer computers, and then the xml/images would be converted to html by downloading much less data fromn one of the more centralized servers.

  9. Not only for streams on Peercasting Ready for Primetime? · · Score: 4, Interesting

    A community could also run sites like Slashdot with everybody sharing the bandwidth. That might mean no ads, no dependency on a single corporation, everybody can participate in selecting stories, setting "locality" - browsing stories scored by an interest group a reader belongs to, by a group close geographically, or with the score averaged globally.

  10. RGB/CMY devices on Women See Colors Better · · Score: 1

    Do monitors/printers/etc. produce low quality color
    images in the eyes of women?

    Perhaps R1R2GB/CMY1Y2 devices would better fit to
    their needs? :)

  11. Three dots on Rosetta Comet Chaser Images Earth and Moon · · Score: 1

    There are, but Earth and Moon, three small dots visible in the larger image. Anyone knows what they are?

  12. Re:(Submarine) patents? on 3D Sound by Creator of MP3 · · Score: 1

    I mean the kind of patents that, even if they might possibly be very complex and it could take long to invent them, are more like mathematical theories, and very generic. A scientist might read about a theory and develop other theories on basis of this. But, if the scientist is paid by money from patents, then the scientist might want to prevent others from, effectively, using/enhancing/testing a mathematical theory.

  13. Better surround with 4/6 speakers? on 3D Sound by Creator of MP3 · · Score: 1

    Anyone knows if/how the surrond using typical 4/6 speaker sets could be done better using some of the advanced sound wave interference algorithms? Even in a small `fine spot'?

  14. (Submarine) patents? on 3D Sound by Creator of MP3 · · Score: 5, Insightful
    Is not this the same institute that had the submarine MP3 patents? I might be wrong and their work is probably very interesting, but obvious "patents" might perhaps turn it into another GIF/MP3/...-like story.

    Byt the way, anyone knows how is it related to this: Single Speaker Unit Delivers Surround Sound?

  15. Re:Spherical snowflakes? on Mounting Evidence for Water on Mars · · Score: 1

    Some of the spherules are `budding' like it can be seen here, so perhaps the spherules grown in some kind of a seed and deposits process. But perhaps they could just melt or something into one piece. Perhaps some hints about their origin could come from meausuring a set of the spherules and this way finding their size distribution.

  16. Re:Spherical snowflakes? on Mounting Evidence for Water on Mars · · Score: 5, Interesting
    Several of the photographed spherules seem to have various features close to their tops, i.e. they seem to be pointed like here. There is also a photo of a cut of one of the spherules. If you brighten dark colors in the image something like a central stem, dendritic structures in, relatively to the image, upper part of the spherule, and a `glue' to the left of the spherule, can be seen.

    These can be illusions, of course.
