Colossus Cracks Again

BOfH writes "The BBC is reporting that following a 14-year rebuild project, the Colossus computer is once again cracking codes at Bletchley Park." They will crack WWII-era encrypted messages, and compete against modern PCs. Fun stuff for crypto nerds and history buffs.

    It's a great visit. Go check it out. They don't get a lot of funding so they are very dependent on visitors (and volunteers if you live nearby) to help keep things going. They had to sell off some of their land recently to keep going (this is now getting turned into a local housing estate).

      I had an amazing day there a few years back - one of the most amazing things was that many of the volunteers were connected to Bletchley Park originally and you could talk to them to get their stories first hand. There are very few opportunities for such things these days and well worth taking the opportunity to meet them (and have a nice cup of tea!)

    The machine is only running at about 30% of the speed it did originally. It appears that their ISP is throttling their packets for some reason. Comcast cited DMCA violations as the reason for the packet shaping.

      There is a full scale replica, at London's Science Museum, made by their own technicians. Its a lovely mesh of bronze and brass cogs and gears, and yes, it does work. I worked there years ago and was told something interesting: Bill Gates funded the construction of the display model on the condition that afterwards, they build him one too. Which I presume they did.

    Probably not ... It's is not Turing Complete, it was designed and built for one purpose (but turned out to be amazingly flexible)

    It could theoretically be rebuilt to run Linux... but the boot times would be a bit slow? The nearest thing it has to a clock speed is the input rate (that was the limiting factor in decoding) normally 5000 characters/second, was run up to 9700 c/s but it effectively did parallel processing so....

  15. One of The First Clockless Systems by TheHawke · · Score: 2, Interesting

    Colossus ran as fast as the tape reader could scan and compare tapes. They estimated that the unit could do as much as 10,000 to 15,000 Characters Per Second (CPS). Material issues kept the machine running dependably at 5,000 CPS. As the story goes, the inventor cranked the tape scanner up to 10,000 CPS and the paper tape failed, sending ribbons flying across the room. At 60MPH, paper flies very fast!
