Colossus has been Rebuilt

Max Driver writes "In celebration of D-Day, "Colossus", one of the earliest electronic code-breaking machines, has been rebuilt after ten years of effort by computer conservationists. Colossus was used to break the Lorenz cipher. This story is being reported by the BBC. Remarkably, the use of parallel processing (five tape channels) and short gate delay time (1.2 microseconds) allows the Colossus to match the speed of a modern PC."

    Phew. For a moment, I thought they were talking about this Colossus.

      Yeah, good for trade, but that is obsoleted by electricity, so why would anyone want to build that now.

    It only matches the speed of a modern PC at the single task it was designed for.

    Yeah, they're still trying to figure out how to make it crash as often.

    Oh great, a load of Slashdotters turning up. I can just imagine the poor guides when they ask the obligatory "Does anyone have any questions?".

    Also they had better rope off the area properly or for some reason the machine will print out "Visit my 1337 site goatse" or "First Post" constantly.

    OK, so we tossed away the computer, aerospace, and other industries.

    But look at the popularity of the ideas we exported; why, in central London a pub has a sign outside saying it was where the Communist Manifesto was launched, and offering themed lunches (borscht etc.) (oddly I can't remember a similar sign outside the hofbrauhaus in Munich). Who would have thought that would take off?

    I really put that down to two things:

    1) Most people in England still only have 486 computers
    2) He's talking about deciphering stuff off a paper tape, something a modern PC can't do at any speed
    3) An old guy bragging about life's accomplishments (which is okay).


    At least we can count.

    Cocks is now chief mathematician at GCHQ; and given that he's probably intercepting this communication as I write, I dare say he will pop-up if what I've said is inaccurate!

    Well, yes, GCHQ have almost certainly logged this communication - as will Google in the not too distant future, so that's not so cloak-and-dagger... But I doubt the great man will actually turn up. More likely some large men will be coming around to explain to you why, if you're going to make fun of people's names, it's perhaps wise to pick people who aren't highly placed members of large international espionage organisations...
