extract_url.pl is a Perl script that extracts URLs from either correctly-encoded MIME email messages or from plain text. It can be used either as a pre-parser for a URL selector (such as urlview), or as a standalone URL selector. It is very configurable, can handle URLs that have been broken over several lines in format=flowed delsp=yes email messages, and eliminates duplicate URLs. It was designed primarily for use with Mutt, but can be used by for any similar purpose. The idea is that if you want to access a URL in an email, you pipe the email to a URL extractor (like this one), which then lets you select a URL to view in some third program (such as Firefox).
PhotoCatalog can import GPS data from various formats such as CSV, GPX, and InstaMapper (in the case of InstaMapper, it is a live stream) and create a Map that is updated live during your travels. It can also import data from Twitter or FourSquare, RSS extract any GPS data they have or supplement them with existing GPS data, and place them on a map as well as keeping a personal archive. It can then import photos via file upload, email, or scanning an existing folder, geotag photos lacking GPS data, sort, rotate, scale, and [losslessly] compress them as necessary and place them on a map. It can also push them to Facebook automatically and fill in a caption and/or comment with them.
