ErlangCamp is back, this time in Coruña Spain the 5-6:th of October.

We felt it our duty as good upstanding engineers to let you know about ErlangCamp 2012 which will be held in Coruña Spain this Oct 5th and 6th.

Why Erlang? Why ErlangCamp? And what could I possibly learn in two days?

In two days, you learn how to build world-class solutions using the technology that powers NoSQL data stores like Basho’s Riak and CouchDB, enterprise messaging platforms like VMWare’s RabbitMQ and ejabbard, Erlang Solutions’ OpenFlow software-defined network (SDN) switch LINC, VoIP platforms like Kazoo, financial exchange systems, and commercial solutions from companies like Ericsson, Klarna, Campajna, Tail-f Systems, 2600Hz, Machine Zone, ShoreTel, and Quviq.

Your instructors are experts at developing real-world Erlang/OTP-based solutions, including two of the authors of the "Erlang and OTP in Action" (http://manning.com/logan)

And, of course, you will be at the Universidade da Coruña, in scenic Northern Spain (Note* the program is in English). Take a couple extra days, and make it a working vacation!

For more information see the ErlangChamp website (http://erlangcamp.com) or email info@erlangcamp.com.

Spawnfest, a 48 hours programming contest for Erlang, is back again this year. It is scheduled for July 7-8, and open to any team of 1 to 4 members. Prizes to be given!

It's a great opportunity to show the world what Erlang/OTP and its users are capable of. The contest is in no way limited to web applications or any specific domain; diversity of entries is embraced.

Participants will see their entries judged by Eric B. Merrit ( founding member of the Erlware, co-author of "Erlang and OTP in Action"), Joe Armstrong (co-inventor of Erlang), Loïc Hoguin (Founder of Nine Nines, writer of Cowboy), and Scott Lystig Fritchie (long-time Erlang user, senior software engineer at Basho, worked on D-Trace for  Erlang, and so on).

You can register your team at http://spawnfest.com/

The description below is an excerpt from Erlang Solutions download page.

Erlang Solutions has the facilities to port Erlang to your operating system and hardware platform of choice. We have ported Erlang to a wide range of configurations, from embedded to high specification servers. These have included HiPE enabled, 32 and 64 bit configurations, alongside the half-word emulator. We have worked with operating systems such as VxWorks, OSE Delta, QNX, Android and iOS as well as the most popular operating systems. We are able to create and test customized binaries where your applications are packaged and tested alongside the OTP ones on the hardware / operating systems of your choice. Packages and ports that we are currently building and testing free of charge include popular Linux, Mac OS X and Windows versions. They can be downloaded from their Erlang Download page.

Erlang/OTP R15B has been released as planned on December 14:th 2011.

See the release notes in the readme file.

Download the new release from the download page.

We have recently pushed a new master to GitHub tagged OTP_R15A.

This is a stabilized snapshot of the current R15 development (to be released as R15B on December 14:th) which, among other things, includes:

OTP-9468  'Line numbers in exceptions'

OTP-9451  'Parallel make'

OTP-4779  A new GUI for Observer. Integrating pman, etop and tv into
                    observer with tracing facilities.

OTP-7775  A number of memory allocation optimizations have been
             implemented. Most optimizations reduce contention caused by
             synchronization between threads during allocation and
             deallocation of memory. Most notably:
             Synchronization of memory management in scheduler specific
             allocator instances has been rewritten to use lock-free
             synchronization.

             Synchronization of memory management in scheduler specific
             pre-allocators has been rewritten to use lock-free
             synchronization.

             The 'mseg_alloc' memory segment allocator now use scheduler
             specific instances instead of one instance. Apart from
             reducing contention this also ensures that memory allocators
             always create memory segments on the local NUMA node on a
             NUMA system.

OTP-9632  An ERTS internal, generic, many to one, lock-free queue for
             communication between threads has been introduced. The many
             to one scenario is very common in ERTS, so it can be used in
             a lot of places in the future. Currently it is used by
             scheduling of certain jobs, and the async thread pool, but
             more uses are planned for the future.

             Drivers using the driver_async functionality are not
             automatically locked to the system anymore, and can be
             unloaded as any dynamically linked in driver.

             Scheduling of ready async jobs is now also interleaved in
             between other jobs. Previously all ready async jobs were
             performed at once.

OTP-9631  The ERTS internal system block functionality has been
             replaced by new functionality for blocking the system. The
             old system block functionality had contention issues and
             complexity issues. The new functionality piggy-backs on
             thread progress tracking functionality needed by newly
             introduced lock-free synchronization in the runtime system.
             When the functionality for blocking the system isn't used,
             there is more or less no overhead at all. This since the
             functionality for tracking thread progress is there and
             needed anyway.

... and much much more.

This is not a full release of R15 but rather a pre-release. Feel free to try our R15A release and get back to us with your findings.

Your feedback is important to us and highly welcomed.

Regards,

The OTP Team

ErlangCamp is back, this time in Boston. This year we have partnered with Erlang Solutions and their Erlang University Program. There is not enough information out there relating to how you write real production grade Erlang systems. ErlangCamp is a 2 day inexpensive workshop (12-13 August) that teach exactly that. The workshop will teach participants how to construct solid production grade Erlang OTP software. Among the instructors are the authors of Erlang and OTP in Action.

Erlang/OTP R14B03 has been released as planned on May 25:th 2011. It is the third R14 service release.

See the release notes in the readme file

• All test suites now run with CommonTest

Erlang/OTP R14B  will be released on September 15th. This is 2 weeks later than previously announced.

Members of the Erlang/OTP team is giving presentations at the Erlang Factory conference in the SF Bay Area March 25-26

Patrik Nyblom is giving a presentation with the title "Erlang SMP support, behind the scenes" and Kenneth Lundin will present "Latest News from the Erlang/OTP team".

Erlang/OTP R13B04 has been released. R13B04 is a service release for R13B. There are mostly error corrections, but also some new functionality.
This is the first release after the introduction of the official Git repository at Github and it is amazing to notice that the number of contributions from the community has increased significantly. As many as 32 contributors have provided 1 or more patches each until now, resulting in 51 integrated patches from the open source community in this service release.
In addition to the contributions provided by the community we have the following examples of highlights in the release:

• The documentation can now be built from the source.
• The Native Implemented Functions (NIFs) are still in beta, but much enhanced.
• The garbage collection of binaries is further enhanced.
• Support for user defined prompt in the shell. A small but useful new function.
• Enhanced cross compilation support
