1.     Algorithm of the Week: Longest Increasing Subsequence
A very common problem in computer programming is finding the longest increasing (decreasing) subsequence in a sequence of numbers (usually integers). Here's a practical way to do so.

2.     Debugging “object has no properties” in a MongoDB map/reduce
You got to love debugging JavaScript errors. Here’s an interesting one from a MongoDB map/reduce and how to resolve it.

3.     Running Cassandra 1.2-beta on JDK 7 w/ Mac OSX
The latest greatest Cassandra (1.2-beta) now uses snappy-java for compression. Unfortunately for now, Cassandra uses version of snappy-java. That version of snappy-java doesn't play well with JDK 7 on Mac OSX.

Upcoming Webinars

Simplifying Persistence for Java and MongoDB 

Thursday December 13th 10:00am PST / 1:00pm EST / 6:00pm UTC

Jeff Yemin, an engineering manager at 10gen, will host a webinar covering the design and major features of Morphia, an Object Document Mapper (ODM) for Java and MongoDB. This webinar will start with a short introduction to MongoDB and the various options for building MongoDB applications on the JVM before taking a deep dive into Morphia. Morphia will be presented as an extended example format that demonstrates, for each feature, the domain model, a test driver, and the results as they appear in MongoDB.

Thanks for reading! See you next week!
