Leon Brocard (aka acme) is an orange-loving Perl eurohacker with many varied contributions to the Perl community, including the GraphViz module on the CPAN. YAPC::Europe was all his fault. He is still looking for a Perl Monger group he can start which begins with the letter 'D'.

Reversible computing

[ #34129 ]

Computers should be reversible. If you parse something, be sure to also format it. If you allow something to be installed, allow it to be uninstalled. If you delete a photo in your web app, allow it to be undeleted. The future needs ubiquitous undo. Please make everything more flexible.

  • A gentleman who was working on a new parser for my AI::Prolog managed to get things a bit confused at one point and the compiler was running backwards. Of course, since this is logic programming, it still printed out correct answers. The reason I couldn't use his nice parser is because math in Prolog is inherently non-logical (ironic, eh?) and therefore can't be run backwards.

    I think you'd find that functional languages have this property, too. It's the procedural and OO ones that will give you fits.

  • If I delete something from an online web service I really want it deleted. This might be for privacy reasons, and I don't want you archiving it and having to give it up under subpoena.
