VoltDB: a pure SQL, pure ACID, pure OLTP, shared nothing, sharded, scalable, lockless, open source, in-memory DBMS, purpose-built for running hundreds of thousands of transactions a second. VoltDB claims to be 100 times faster than MySQL, up to 13 times faster than Cassandra, and 45 times faster than Oracle, with near-linear scaling.

Clojure is a beautiful language, but if its community wants more people to appreciate the language, then it may want to consider making the getting started experience beautiful too.

Follow the link for a diagram.
It's not often that you can make traffic flow more smoothly and safely without spending significant time and money. But drivers in Springfield, Mo., are the first in the United States to use a new interchange design that transportation officials say is quick, cheap, and safe.
The "diverging diamond" is being put to the test. Fans of the new highway interchange design say it improves traffic flow by eliminating problematic left turns. There's just one catch: It briefly sends all cars over to the left side of the road.

>> Contact the makers of these plug-ins for versions that are compatible with Mail 4.3 and Message 4.3. I reported the problem to Plaxo.com. As long as the rest of plaxo works, I'm not too worried, but I'll need to do some more testing before I'm sure it's OK. By the way, Plaxo is a free tool that synchronizes your contacts and calendars among several computers. It mostly works fine.
or relational algebra.
Carte is relational mapping for Clojure. It maps nested immutable data structures to an underlying relational database management system. It is meant only to provide simple access and manipulation of relational data, it is not meant to be a replacement for SQL

In Watson’s 1982 U.S. Open win at Pebble Beach, he holed a touchy chip shot from the greenside rough to birdie the 71st hole—arguably one of the greatest pressure shots ever—and then birdied the 18th to top Nicklaus.

To use the datastore API I need to include a jar that comes with the GAE SDK in my app. I could call the Java API directly, but there are already a few Clojure libraries that provide friendly wrappers around it. One of the first (that I know of) was appengine-clj by John Hume (who was also one of the first to write about using Clojure on GAE).
I decided to go with this fork of appengine-clj by Roman Scherer, which seems to be more complete and actively maintained.
