There’s no Linux client/browser integration for 1Password which is more than a bit annoying - especially when you have multi-boot machines. I wrote a quick perl script which allows read-only access to a 1Password AgileKeychain. If I receive inquiries, I may publish some copy of this tool.
LinkShare is a small web application for sharing URL’s via RSS feed. URL and some other details are submitted by a user. RSS feeds are generated by another small script. There’s also companion Chrome and Firefox plugins.
