Although development has only started, Google has announced their first commits of Git Ketch, a multi-master Git management system that replicates information across multiple Git servers for resilience and scalability. The changes are based on JGit, a Java-based Git server, although other Git servers may be part of the multi-master cluster.
FoundationDB has announced the general availability of SQL Layer, and ANSI SQL engine that runs on top of their key-value store. The result is a relational database backed up by a scalable, fault-tolerant, shared-nothing, distributed NoSQL store with support for multi-key ACID transactions.
Amazon Web Services (AWS) has recently integrated the AWS Trusted Advisor into the AWS Management Console and made four security and service limit checks available at no charge. Additional checks from the security, performance, fault tolerance and cost optimization categories remain part of their Business and Enterprise support tiers.
The Netflix API optimization story is an interesting journey from a generic one-size-fits-all static REST API architecture to a more dynamic architecture that lends power to the client team to define and deploy their custom service endpoints. InfoQ spoke to Ben Christensen regarding this client adapter layer as well as the services layer redesign.
A Cornell University professor claims MongoDB’s fault tolerance system is “broken by design”. 10gen responds through its Technical Director, rejecting the claims.
Netflix has released Hystrix, a library designed to control points of access to remote systems, services and 3rd party libraries, providing greater tolerance of latency and failure. Hystrix features thread and semaphore isolation with fallbacks and circuit breakers, request caching and request collapsing, and monitoring and configuration.
For the first time since 1993 Microsoft is posed to offer a new file system architecture. ReFS or Resilient File System is designed to both improve reliability and as a chance to drop obsolete features offered by NTFS.
Akka 1.1 was released with many improvements in performance, Futures and more. The basic Akka also has no dependencies except for Scala 2.9. InfoQ caught up with Jonas Bonér to talk about the current state and the future of Akka.
Scala creator Martin Odersky joined forces with Jonas Bonér, the creater of Akka, and launched Typesafe. With $3 million Series A financing led by Greylock Partners, Typesafe offers commercial support for enterprise development of multicore and cloud architectures.
Ruby has long been criticized for 1.8's limited green threads. Luc Castera gave a presentation at RubyNation about Concurrent Programming with Ruby and Tuple Spaces. He introduces 2 ways of implementing TupleSpaces in Ruby: Rinda and Blackboard using Redis (with plans to porting it to Erlang).
The topic of distributed transactions and their place within a REST world has come up again recently. Many people have indicated that they are either thinking of using the combination or are doing so now. Others, including Roy Fielding, believe that the two simply do not go together.
The WCF Client code violates two of the core principals of .NET API design; calling Close should actually close the connection and calling Dispose should never throw an exception. We look at how this came to be and at some available workarounds.
In this talk from RubyFringe, Damien Katz explains what drove him to create CouchDB, why he chose Erlang, how it ended up as an Apache project and much more.
Aster Data Systems has announced an in-database MapReduce implementation for their nCluster database platform.
In his position statement for the International Computer Music Conference 2008, Peter Van Roy raises a number of issues related to the emergence of multi-core processors and loosely coupled systems and suggests possible solutions. Though challenges brought by these two forms of concurrency computing are very different in their nature, both they go beyond purely technical problems.
