Code Portfolio
My two favorite Perl statements:
  $min = [$x => $y]->[$y <= $x];
  %is_thing = map { $_ => 1 } @things;
(Note: I only use one of these in production code.)

The links below contain samples of code I have written in Perl and other languages.

update_infoblox.pl - a script that updates DNS records on an Infoblox appliance from current NIS host records.

Heredoc::Unindent - a source filter that allows you to properly indent "here documents".

xdf (eXtended Disk Free) - a replacement for df, which only shows local filesystems, includes universal support for "human readable" output, and provides sorting options and other features.

SubUtils::CheckCall - a module for doing detailed subroutine call checks, including verifying calling context and argument count/type.*

SuDoku Solver - I enjoy SuDoku puzzles but eventually decided just to solve the general problem.*


exec_upload.php - a PHP form handler that accepts multiple uploaded images with descriptions and categories, saves them in a non-web-accessible location, generates a thumbnail and watermarked medium-quality image for search results, and adds them to a database for later searching.
