Google Code Jam Registration Opens Today 129

Bamfarooni writes "Registration for Google Code Jam 2006 opens today. The event consists of 3 online rounds (September 5-6, September 14 and September 19,) in which participants compete to solve three coding problems faster and more accurately than their competitors. If you've got what it takes, and more of it than anyone else, then you can take home up to $10k for your code-fu."

    This is Google's way of recruiting the debuggers to sort out the problems with their programs.
    • Nah. It's more for publicity than recruiting. Look at the venue. Those in the US that want to go to NYC are already there. Those overseas will have trouble with customs, given that they are 1) foreign, and 2) good at hacking code. It would have been smarter to choose Toronto or Vancouver, where it would be safer and easier for the contestants to travel.

      Are the problems going to be more interesting this year? I looked at last year's questions, but they seemed very dull; the kind of things any first year computer science student ought to be able to find an optimal solution to.

      I don't think I am one of the top 100 coders in the world, and so if I entered I probably wouldn't win any money. This being the case, the only reason to enter would be for the intellectual challenge; something which seems to be missing. And Google wonder why they have a problem

      • Part of being a good programmer means picking the right tool for the job. I looked at some of the questions last year, and found I could answer them in about half as much Smalltalk as Java. The Smalltalk was also more readable, and more flexible. Programming in any of the languages they list is like typing with one hand; you might want to try it for a bit, but it's not something you would pick when you needed to be productive.

      All they say is that you cannot use TopCoder plugins or modify the applet, but do not consider it cheating to copy the problem statement into another IDE, do your development there, and copy the code back. In fact, a good handwritten (e.g. you wrote it yourself and did not get it from a TC plugin) regular expression or two should suffice to parse the problem statement into class/method stubs and test cases. You tie running that regular expression to a macro and you're all set.
    • Not at all. Use your own IDE, then cut and paste into theirs when you're happy.

      Anyone have any idea on the difficulty of the problems? The language choices suck, but I'm still curious as to what kind of problems they throw at you.
