    • In a 2008 reenactment, Joachim Schüeth won the National Museum of Computing's Colossus Cipher Challenge. Using his laptop, Schüeth unravelled a code transmitted from the Heinz Nixdorf Museum in Germany, from an actual Lorenz SZ42 Cipher machine used by the German High Command to relay secret messages during the World War II You can read the story in Dr Dobbs Journal at http://www.drdobbs.com/parallel/tunny-colossus-and-ada-keeping-an-open/207800151. Or Google "Tunny, Colossus and Ada: Keeping an Open Mind" to find the article. John

    • We still teach Ada to our students at the University of Northern Iowa. From 2000 to 2007 we taught Java in CS1 and CS2 and Ada in CS3. The faculty unanimously agreed that our use of Java for beginners was a failure. Starting in the Fall of 2007 we began two parallel tracks for Freshman. One track taught C/C++ in CS1 and CS2, the other Ada. Students now get Java in CS3. The first groups took CS3 last Fall. The CS3 teacher reported that in the final grade distribution ALL of the students with the Ada background did better than those with the C/C++ background. Numbers are too small yet to publish an education article, but it is certainly looking strong for Ada as a good language for teaching beginners.
