FixMyStreet Platform is an open source project to help people run websites for reporting common street problems such as potholes and broken street lights to the appropriate authority.
 
Users locate problems using a combination of address and sticking a pin in a map without worrying about the correct authority to report it to. FixMyStreet then works out the correct authority using the problem location and type and sends a report, by email or using a web service such as Open311. Reported problems are visible to everyone so they can see if something has already been reported and leave updates. Users can also subscribe to email or RSS alerts of problems in their area.

Postgrey is a Postfix policy server implementing greylisting developed by David Schweikert. When a request for delivery of a mail is received by Postfix via SMTP, the triplet CLIENT_IP / SENDER / RECIPIENT is built. If it is the first time that this triplet is seen, or if the triplet was first seen, less than 5 minutes ago, then the mail gets rejected with a temporary error. Hopefully spammers or viruses will not try again later, as it is however required per RFC.
