Escapes.js is a tiny JavaScript library for rendering ANSI art, a form of computer art that flourished in the mid 90s. ANSI art is a form of art, created by colorizing sequences of characters and blocks drawn in the built-in system font, which makes it easy to transmit across telephone wires. As a result, ANSI art was especially popular on Bulletin Board Systems (BBSes).  

Escapes.js is a library developed by Ori Livneh (@scatterblot), designed to be simple and fun to hack on. It has no hard dependencies, but it integrates neatly with jQuery. The source code and documentation are available on GitHub.

MySQL Cluster 7.2 was released to public by Oracle on Wednesday, Feb 15, 2012. "MySQL Cluster 7.2 demonstrates Oracle’s investment in further strengthening MySQL’s position as the leading Web database,” said Tomas Ulin, vice president of MySQL Engineering, Oracle. “The performance and flexibility enhancements in MySQL Cluster 7.2 provide users with a solid foundation for their mission-critical Web workloads, blending the best of SQL and NoSQL technologies to reduce risk, cost and complexity.”

MySQL Cluster 7.2 release added improvements in autosharding the data and replication conflict resolution in addition to some scalability and reliability improvements that allow replication at different data centers. There was also some work in fixing issues with replicating user privileges and making the clusters easier to manage and administer. As well as some work done to certify and integrate the cluster nodes into the Oracle VM infrastructure to take advantage of increased elastic scalability for cloud deployments. MySQL Cluster 7.2 in now certified to run on Oracle Linux and Oracle Solaris.

Regarding the 70x improvement in complex query speed ("mind blowing numbers"), Tomas mentioned that this was accomplished with what they call "push down joins" or "distributed joins" which sound a lot like a MapReduce specific use case to do a distributed join on a heavily sharded relational database. The joins happen to the actual data nodes. They are done in parallel on all of the nodes, and then one node combines them. The parallels of the join is where the speed comes in. Tomas claims billion queries per minute with an 8 node cluster and near linear scalability in join processing by adding new nodes.

Dynode is a node.js client, which enables you to work with Amazon's DynamoDB service with ease. Amazon's http api is complex and interacting with it is not so easy. This client does offer a simpler and more obvious way of working with DynamoDB, notably, without putting any restrictions on what you can accomplish with DynamoDB.

There are two different ways to use dynode: directly via the default dynamoDB client, or by instantiating your own client. The former is merely intended to be a convenient shared client to use throughout your application if you so choose.

Using the Default DynamoDB Client

The default client is accessible through the dynode module directly. Any method that you could call on an instance of a client is available on the default client:

var dynode = require('dynode');

  // When using the default client you must first give it auth credentials
  dynode.auth({accessKeyId: "AWSAccessKey", secretAccessKey: "SecretAccessKey"});

  dynode.createTable("NewTable", console.log);
  dynode.listTables(console.log);

Instantiating your own DynamoDB Client

If you would prefer to manage your own client, potentially with different auth params:
