  1. Re:Maybe its time for a new 35mm film? on Kodachrome Takes Its Final Bow Today · · Score: 1

    Kodak Ektar 100, which was launched about 2 years ago, is maybe the closest current film to what you're suggesting. It's very fine-grained and designed for scanning, though you only get ISO 100, and the chemistry is standard C41 colour negative (which realistically it has to be - nobody is going to do R&D on an entirely new film process at this point, and finding decent local processing is already hard enough):

    Kodak at one point made an automated Kodachrome minilab, the K-Lab, which was intended to make processing more widely available:

    Unfortunately it never really took off, and one was up for sale for several years with no takers:

    Obtaining the necessary processing chemicals, especially the proprietary dye couplers, is the major barrier to making this happen.

    'I like the fact that the EXIF data has the camera serial number. Over the years, I've used a number of different cameras. Even multiple versions of the same model. It's nice to have that information in the database. Giving it to anyone else is another issue entirely.'

    Yes, distribution is the issue. I use Nikon dSLRs, where the embedded serial number has a couple of interesting consequences:

    First, the serial number is used as one of the keys used by recent cameras to encrypt Nikon's 'MakerNote' metadata (the other keys are the 'shutter count' and Nikon's secret key, which has fortunately been cracked and is available in the dcraw and ExifTool source). The MakerNote holds some useful pieces of data, including the 'as shot' white balance value required for 'correct' processing of Nikon's NEF raw files (Adobe made a lot of fuss about this until Nikon gave them a decryption 'mini-SDK' that could be incorporated into Photoshop). If the serial number has been stripped from the NEF, the MakerNote can no longer be decoded. You can't therefore distribute a fully-functional NEF without leaving in the serial number.

    Second, anyone with access to one of your files containing the serial number can, e.g., use it to register on Nikon's support site (possibly preventing you doing so later), or even make a malicious fake report that a camera bearing that serial number has been stolen.

    'But here again, the onus is on the individual to know how to deal with one's complex modern objects. For EXIF data, it's easy to strip entirely or individually.'

    I think a lot of people won't realise the serial number is embedded at all (I can't see it using Nikon's own View NX software, only with 3rd party software like ExifTool), and if they do, it may not be obvious how to get rid of it, or the possible problems that doing so may cause.

    '...the entire genome is only 850,000,000 bytes which is 810.6MB'

    That's about right - the reference assembly from UCSC is 778Mb in their standard .2bit format. That's just a single sequence for each autosomal chromosome plus one each of X and Y, though - you'll need to allow about double that to store your full dipoid genome, so better buy a 2Gb flash drive. On the other hand, if you take the reference sequence as a given and only store the differences between it and yours, you only need about 4Mb!:

    http://www.ncbi.nlm.nih.gov/pubmed/18996942

    But raw sequence data is a different matter. To call each base confidently everything has to be sequenced multiple times (it's normal to go for something like 40x coverage on an Illumina machine). And you'll probably have to deal with the files as uncompressed ascii text (or gzip/bz2 at best). When you start analysing the data, you'll need a lot more space to store the alignments to the reference sequence, and you'll need some reasonable computing power to do the processing (which may well take longer than generating the data).

    Indeed. The 2-bit encoded human genome available from UCSC runs to 778Mb, or a conventional gzipped ASCII file is 905Mb. Better compression is an active area of research. Depending on the complexity of the input sequence and the compression algorithm, various values in the 1-2 bits/base pair range have been quoted, see e.g.:

    http://fabrice.lefessant.net/papers/cpm2005.pdf

    But that still leaves you far short of Kurzweil's supposed compression ratio, unless you allow this sort of cheating:

    http://www.ncbi.nlm.nih.gov/pubmed/18996942

    This trick relies on comparison to a known standard reference sequence, and therefore doesn't say anything about the information content of the genome in general (so it's no good for Kurzweil's argument).

    'Then again, if you skim the "junk DNA" (which may or may not really be junk), you can shrink it quite a bit'

    If you include only protein-coding genes and discard the rest as 'junk', you can get to around Kurzweil's number in uncompressed ASCII. But that really is cheating. There's lots going on outside the proteome:
