Kazuho@Cybozu Labs: Mycached: memcached protocol support for MySQL
It is a well-known fact that the bottlenecks of MySQL does not exist in its storage engines, but rather in the core, for example, its parser and execution planner. Last weekend I started to wonder how fast MySQL could be if those bottlenecks were skipped. Not being able to stop my curiousity, I started adding memcached proctol support to MySQL as a UDF. And that is Mycached. From what I unders
Moxi - Memcached Proxy
Moxi is a memcached proxy that allows clients like PHP applications to connect to it instead of directly to memcached servers. It handles protocol conversion, failure handling, consistent hashing of keys, and GET deduplication to improve performance. Moxi can also act as a front cache and support configurable features like timeouts, blackhole mode, and fire-and-forget SET operations.Read less

I guess most people don't know this, but I'm the only member of the technical team in NorthScale located in Europe. I live just outside Trondheim in Norway, so it's pretty far from everything. So why did I join NorthScale? A lot of my friends in Trondheim have been asking me that question. To them it sounds strange that I want to work from home for a company located 9 timezones away.
