Friendfeed contact categorizer
This Perl script sorts your Friendfeed contacts according to reciprocation, i.e. it shows who are your mutual subscriptions, only subscribers, and only subscriptions. Because this script doesn't authenticate with Friendfeed, it doesn't work on users with private feeds.

Perl script to merge/convert EasyGPS binary .loc files and Geocaching .loc files
This script reads waypoints from any number of EasyGPS binary .loc and Geocaching .loc files on the command line (wildcards supported in DOS/Windows), combines all those waypoints, and sends the result in Geocaching .loc format to standard output.

This is useful if you are using an older version of EasyGPS to edit waypoint files but wish to convert and merge waypoint files into the Geocaching .loc format for use in newer versions of EasyGPS.

Note: gcmerge.pl produced incorrect UTF-8 output until I installed XML::SAX. I do not know why it was broken before but this is worth a try if EasyGPS complains about invalid characters in the Geocaching .loc format output from this script.

Update 1/25/2010: Added support for reading GPX files.

Update 2/25/2010: Slurp in entire waypoint files and implement buffering ourselves for speed.

Import Delicious bookmarks into Evernote.
This Perl script takes an export file from Delicious and imports the bookmarks into Evernote, creating one note for each bookmark. This script is slow if you have a large number of bookmarks because it has to create the notes one at a time. I hope the Evernote API will one day support batch note creation.

Customize this script by adding your Evernote API consumer key and secret before you use it.

Pidgin plugin that copies to the clipboard each IM that you send
I use this plugin in conjunction with a clipboard manager utility. It's a crude way to have a history recall of sent IMs.

Autohotkey macros for copying coordinates
These two macros take coordinates from the clipboard, whether in dd.ddddd format or in dd mm.mmm format.

Then the first macro pastes dd.ddddd format coordinates into two form fields with 2 tabs separating the fields. The second macro does the same but with 1 tab instead of 2.

Use the first macro for Geosnapper and the second for Streets and Trips.
