I am pleased to announce the next Xen Project Hackathon to be held this spring. Although we call it a Hackathon, the event consists of several parallel sessions in which Xen Project developers will create, discuss and review designs and changes that impact Xen’s architecture. We’ll perform code reviews, discuss our future roadmap, work on improving the development process, tackle debug problems in the code base and cover other development related topics. Sessions are very interactive: typically there are no presentations.
GTID replication is new in mysql 5.6 and adds an unique ID to every transaction on the database. That transaction ID is then used to ensure the transaction is applied on the slave.

I am currently working on log normalization as well as improvements for rsyslog's imfile. Among the things that regularly come up on the rsyslog mailing list is support for multi-line logs and Java stack traces in general.I would like to see what I can do to improve processing of these. To do so, I need a set of samples of such logs. As such, I look for people who would like to contribute log records for my research.
