  • Will Wall Street require Python?

    Posted April 19, 2010 - 12:44 pm

    One surprising element of regulatory response to the last years' financial catastrophes is a move to expression of complex contracts in executable programming languages, rather than legal verbiage. Python takes a leading role in an early proposal.

  • Port Forwarding with Perl

    Posted September 10, 2008 - 6:00 am

    SSH tunnels aren't the only way to do port forwarding. If you're clever enough, you can write your own program. If you're not quite that clever, you can use someone else's program -- like a very cool Perl script I found on the web.

  • Connection testing with Perl

    Posted August 21, 2008 - 5:11 pm

    If you've never used the Perl Sockets module for basic connection testing, you might be surprised at how easily you can craft a very useful script. I find my version of a Perl "listen" script to be as useful as a cable tester!
