    Similar thing happened with Tektronix back in the day. A big part of their business was supplying to the US DOD. But in an attempt to reduce cost the DOD placed an order with Hickock and Lavoie, saying that they wanted them to copy the Tektronix scopes. Tek got wind of it and started putting a random hole in the rear panel of the vertical plugin.

    When this appeared in the Hickock copy, Tektronix sued the UK government in 1961. Took a while (18 years!), but Tek won $4.5m in damages from the US Government.

    So "mistakes" can show up a plagiarizer of the design.

    Well, those dovetails are machine made, so no real expertise needed.

    Not sure about that; those pins are pretty narrow. It's possible they used a thin kerf table saw blade, but the narrowness and inconsistency looks like a hand saw to me.

  6. Podcast Thread

    Posted · Edited by dsavitsk

    There is a podcast called The Julia La Roche Show. It's basically a series of interviews dealing with macroeconomic and market issues. The host is not particularly good as an interviewer, but that turns out to be more feature than bug as she tends to have smart people on her show and she just lets them talk. Anyway, this is not a recommendation for the podcast in general as there are better ones on the same topic.

    However, one recent interview is worth a listen. It's with Scott Galloway (a B-school professor at NYU). I don't think he is right about everything, or really anything in particular, so this isn't an endorsement of his views, but I think what he has to say is interesting and worth listening to. The first few minutes are pretty banal middle class investment stuff, but it gets more interesting.

  19. The Official Head-Case Photography Thread.

    An interesting take on the fall of Kodak. Not new, but not a perspective I'd seen before.

    According to Kamal: “The people taking pictures suddenly changed, from 60% women to 70% men. Kodak didn't know how to market to men. But even if they could get them to buy, they didn't want to, because men don't print. Unlike women, they hadn't been socialised in the role of family archivist."

    I do have a bit of concern on this technology, as it's my belief that people can become complacent and get careless because of a false sense of security. I have been using table saws from the age of 12 (51 years). Every time I'm operating a table saw I block out everything else and put my full attention into the use of said saw

    And yet, if you'd had that technology, you'd have 5% more finger than you currently do.
