Apache Qpid. A new open source AMQP message queue with implementations in C++ and Java, developed by engineers from Red Hat, IONA and JP Morgan Chase. Anyone tried this yet? Looks pretty good on paper. # 5th February 2009, 11:01 pm

google-mobwrite. Neal Fraser’s terrifyingly clever differential synchronization algorithm (for SubEthaEdit-style collaboration over the web) is now available as an open source Python and JavaScript library. # 24th January 2009, 11:55 pm

Project Voldemort. Yet Another “big, distributed, persistent, fault-tolerant hash table”—this time from LinkedIn, released under the Apache 2.0 license. The approach to consistency is interesting—instead of using distributed transactions, they use versioning and “resolve inconsistencies at read time”. It also uses consistent hashing (as seen in libketama) to select servers. The design document has lots more information. # 17th January 2009, 7:45 pm
