  1. Re:It's crap on Double Your Fun with DoubleSight · · Score: 1

    While it sounds nice to put CRT monitors cheek by jowl, that
    will cause odd shimmy screen misbehavior. Trust me, I've
    done it. You need a few inches space (on the order of half
    the width of a monitor) separation to keep CRT displays
    happy.

    Single LCD displays at 30" are big enough for any single
    window of info, and very pretty (if you can afford Apple's biggest and best).

    For cheapskates like me, the old CRT still has a few years of useful life. Tubes rule!

  2. Re:The Innocence Project on Chimera Twins Story · · Score: 1

    Chimeric DNA confusion is unlikely to explain
    the high incidence of proven innocence; in Illinois, something like 20% of the death row population got freed (leading the governor to so distrust the judicial process that he took the extreme step of commuting all death sentences to lesser punishment).
    It's very unlikely that the chimeric population is high enough to account for that. If one in a few
    thousand is chimeric, and one tenth of those are chimeric in a way that matters to the evidence, and there are 100 executions in a year... a century could pass before a guilty party is acquittted.

  3. Chimeric twins- not a new issue on Chimera Twins Story · · Score: 1

    For a fine exposition on the legal implications, in the old-science view, I'd recommend the Mark Twain novel _Pudd'nhead_Wilson_ It's of some interest, too, to the enthusiasts who are trying to get DNA data on all felons, and would like to get it on all citizens and visitors as well. They can't claim to have a magic bullet anymore (but the more important issue, for crime solving, is whether there'd be any false positive matches, and twins are the big issue there).

  4. Re:Composite in post-grad studies on Self-Healing Composites · · Score: 1

    This is reminiscent of a technology that goes back quite a ways.
    A porous cemented-fiber composite is impregnated with a monomer/catalyst mixture.
    The monomer polymerizes to a weak solid in presence of the catalyst (which adheres to the fibers) to strengthen the composite, and in case of a fracture, the liquid monomer wicks to the newly created surfaces and both straightens the fibers (by surface tension) and fills the gaps.

    Now a little shift of viewpoint; the porous cemented-fiber composite is 'wood', the monomer/catalyst mixture is 'boiled linseed oil', and the fracture scenario is 'scratch the finish and a few hours later the scratch heals up'.

    This variant of the technology goes back a few
    years. :-)
