Cassandra is a hybrid non-relational database in the same class as Google's BigTable. It is more featureful than a key/value store like Dynomite, but supports fewer query types than a document store like MongoDB. This does not mean that SQL as a general-purpose runtime and reporting tool is going away. However, at web-scale, it is more flexible to separate the concerns. Runtime object lookups can be handled by a low-latency, strict, self-managed system like Cassandra. Asynchronous analytics and reporting can be handled by a high-latency, flexible, un-managed system like Hadoop.

The advent of file sharing has weakened copyright. Today, more than 60% of internet traffic consists of consumers sharing music, movies, books, and games. Yet file sharing has not undermined the incentives of authors to produce new works. The cannibalization of sales that is due to file sharing is more modest than many observers assume. File sharing increases the demand for complements to protected works. And monetary incentives simply play a reduced role in motivating authors to remain creative.

If you've read this far, then you probably intend to use dbacl to automatically classify text documents, and possibly execute certain actions depending on the outcome. The bad news is that dbacl isn't designed for this. The good news is that there is a companion program, bayesol, which is. To use it, you just need to learn some Bayesian Decision Theory.

One of the things he meant was that the question of whether we can mean is a trap, and also an addiction. A sense of fraudulence, of falling short of authenticity, is endemic to contemporary man, just as it is endemic to contemporary art. But it is not the only thing that is endemic to him or his art. It can exist alongside generosity, freedom and truth.

It's going to take a while, but I'm going to prove to you that the nexus where television and fiction converse and consort is self-conscious irony. Television regards irony the way the educated lonely regard television. Television both fears irony's capacity to expose, and needs it.

Twitter disabled the automatic URL shortening if there is any slowness or other problem accessing the shortener. As far as bit.ly goes, they do have an API [http://bit.ly/apidocs] for getting all of the short versions of a long URL, so you might want to give that a shot. We've talked many times about the shortened/lengthened URL issue in search and hopefully we'll come up with a scalable solution at some point.
