Architecting a scalable and dynamic system without caching is explained by Peter Morgan, head of engineering for the sports betting company William Hill. The values of the bets on sporting events change constantly. No data can be cached; all system values must be current. Distributed Erlang processes model domain objects which instantly recalculate system values based on data streams from Kafka.
One year after hitting 1.0, Elixir 1.1 is out. It brings new public APIs, performance improvements, and tooling improvements. InfoQ has spoken with José Valim, Elixir’s creator.
GameAnalytics, maker of a free analytics platform, has recently open sourced gascheduler an Erlang library that provides a generic scheduler for parallel execution of distributed tasks. InfoQ has spoken to Chris de Vries, one of gascheduler’s creators.
The newley released Erlang/OTP R16B brings several performance enhancements among its new features. Code modules can now be loaded in a non-blocking manner, networking code for ports has been improved, and VM processes have been parallelized.
Opscode released Chef 11 early this month with enhancements to its scalability to meet the demands of hyperscale web operations. Opscode rewrote the entire server core API in Erlang and at the same time kept it backward compatible. Opscode renamed the core server API "Erchef" to complement the rewrite in Erlang.
Damien Katz, Couchbase, believes that C is still a great language for back-end programming, while other developers argue that C has too many flaws, supporting C++ or Java, while others like neither.
InfoQ's research initiative continues with an 11th question: "Why Are You Not Using Functional Languages?". This is a new service we hope will provide you with up-to-date & bias-free community-based insight into trends & behaviors that affect enterprise software development. Unlike traditional vendor/analyst-based research, our research is based on answers provided by YOU.
Travis CI, a cloud-based continuous integration (CI) offering for open source projects on Github, has announced support for Java builds, as well as Scala and Groovy additions. After gaining traction among the Ruby open source community the project is now looking into the possibility of expansion to a hosted CI service (nicknamed Travis Pro).
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.
Erlang Co-creators, Joe Armstrong and Robert Virding, admit that Erlang is heavily inspired by the Java world. In an interview at ErlangFactory 2011 SF, they reveal how Scala Actors had shaped their work in what they then called Erlang Processes. Moreover, they acknowledge the fact that Erlang's VM is barely a clone of the famous JVM.
Tiobe's award is given to the programming language that gained most market share in 2010. Objective-C was the leader for most of 2010 but got lost ground in the last couple of months. Python grew it's market share by 1.81% since January 2010, which is nearly 4 times the overall marketshare of SAP's programming language ABAP.
In a QCon London 2010 interview with Joe Armstrong, the original developer of Erlang, and Ralph Johnson, long associated with Smalltalk, OOP, and Patterns, the question of whther we've gone down the "wrong path" w.r.t. object orientation all these yearrs. Both interviewees suggest that we have, but this is due to flaws in the implementation of object ideas and not the ideas themselves.
OpenCredo Ltd has announced support for talking to Advanced Message Queuing Protocol (AMQP) based messagng servers from Spring Integration, a lightweight ESB-like messaging framework. The new support brings MOM vendors whose product doesn't support JMS to users of the Spring Integration framework. Some Message Queues, like RabbitMQ, are very scalable and don't support JMS.
Google's ProtocolBuffers and Facebook's Thrift are options for binary serialization, but not ones that pleased the GitHub team - so they created BERT/BERT-RPC based on the Erlang's 'external term format'. BERT/BERT-RPC now power parts of Github's internal communication.
