- Erlang Factory: Andy Gross: Distributed Erlang Systems In Operation: Patterns and Pitfalls
- Extreme Scale Computing by Irving Wladawsky-Berger. “An exascale supercomputer capable of a million trillion calculations per second – dramatically increasing our ability to understand the world around us through simulation and slashing the time needed to design complex products such as therapeutics, advanced materials, and highly-efficient autos and aircraft.”
- MMT: Exploiting Fine-Grained ParallelisminDynamic Memory Management by lots of people from North Carolina State University. We show that an efficient MMT design can give significant performance improvement by extracting parallelism.
- Ruby Scales, AND It’s Fast – If You Do It Right! by Kirk Haines. The secret to keeping things fast: Do one thing at a time, do it well enough, and then move on.
- Swarm-dpl. A transparently scalable distributed programming language allowing the creation of web applications which can scale transparently through a novel portable continuation-based approach. Swarm embodies the maxim "move the computation, not the data".
- How to Build Stable Google App Engine Apps and sleep better at night by Waleed Abdulla. Be ready, shift happens and App Engine has restrictions. Be Ready. Write good error handling. Update at night. Email critical errors. Backup data.
- Gear6 makes memcached infrastructure lower cost on cloud. Patented Robert Scoble interview with Gear6. What makes us different is that we are extending memcache in obvious ways to make it more useful to people and at the same time we are deploying it to real people and getting real feedback on how it works.
- How Raytheon Researchers are Using Hadoop to Build a Scalable, Distributed Triple Store by Kurt Rohloff. Due to the inherent scalability of the Hadoop and HDFS approach in SHARD, the SHARD triple-store could potentially be used for extremely large datasets (trillions of triples). Also nice description of the query process.
- Infinite web scalability & resilience with Amazon Web Services. Wille Faler provides a simple overview of how to serve semi-dynamic web content with almost infinite horizontal scalability and resilience using Amazon Web Services, with the added boon of making server restores a non-issue.
- Availability and Partition Tolerance by Jeff Darcy. A great discussion of Eric Brewer’s CAP Theorem. You will come away both edified and confused.
- Cassandra Architecutre Internals
New Releases
- Gear6's Memcached Adds the Best of Both Worlds: MySQL and NoSQL. Today's release of Gear6 Web Cache integrates their Memcached interface with operational query capabilities and a NoSQL backend. Gear6 decided to use the key-value store Redis because it already had traction among NoSQL users.
- Amazon Simple Notification Service (Amazon SNS). Amazon Simple Notification Service (Amazon SNS) is a web service that makes it easy to set up, operate, and send notifications from the cloud.
- GigaSpaces XAP 7.1. Adds Elastic Middleware Administration API, a way to deploy applications and data grids into a GigaSpace cluster.
