Colossus, Anon Blogging, and International Blogging

  • In PGP’s CTO Corner, Jon Callas draws attention to the second world war Colossus computer:

    The Colossus Rebuild Project took 10 years and 6,000 hours of effort. The resulting machine is not a replica of a Colossus, but an actual Colossus that uses some of the actual parts. The team finished a Mark II Colossus in time for the 60th anniversary of the completion of the first Mk II Colossus. They even built it in the very place that Colossus #9 was built, on the same concrete pad.

    So how fast is Colossus? Colossus is fast. It decrypts at 5,000 characters per second…If you wanted to program a modern computer to do what Colossus does, you’d need a 2GHz Pentium to match it. Not bad for a machine made out of 2,500 vacuum tubes, eh?

    And the rebuilt machine may be destroyed.
