  • EUC 2014 – Motiejus Jakštys – Large Partially-connected Erlang Clusters
    2014-06-24 Erlang Central

    Videos



    Large Partially-connected Erlang Clusters Have you heard of a Node100 problem? Naïve Erlang clusters are complete network graphs which tend to blow up with a only a handful (100+) number of nodes. Solution is partially-connected mesh networks. The tricky part is easy communication for devs and transparent cluster management for devops. In Spil Games n-tier architecture we use native Erlang message passing between tiers. Thus our cluster size (way over 500) requires partially connected net ...

  • EUC 2014 – Martin Kjellin, Roberto Aloi – Profiling and Debugging Erlang Systems
    2014-06-23 Erlang Central

    Videos



    Profiling and debugging complex Erlang systems can be a challenging and time-consuming task, even for an experienced Erlang developer. In this talk we share our experiences, by covering: * The right mindset and what to look for * An overview of available tools and some considerations from using them * Useful Erlang system information and metrics to consider * War stories (including a widely used piece of Erlang software) * Common pitfalls and caveats   Talk objectives: - S ...

  • EUC 2014 – Mats Cronqvist – Taking the printf out of printf Debugging
    2014-06-23 Erlang Central

    Videos



    Debugging a realtime system is hard, especially if the bugs only appear on a live system. Debuggers cannot be used, and printf debugging is often deemed too risky. The Erlang runtime offers a way to do on-the-fly instrumentation on the function level through the erlang:trace/3 function. This talk will discuss the trace BIF and how to use it. It will also describe redbug, a user-friendly and safe interface to the trace BIF. War stories will in all likelihood be offered. Talk objectives: Descr ...

  • EUC 2014 – Robert Virding – Hitchhiker’s Tour of the BEAM
    2014-06-20 Erlang Central

    Videos



    Hitchhiker's Tour of the BEAM The BEAM is the standard Erlang implementation in use today. It was specially designed just to run Erlang. We will make a quick tour of the BEAM visiting the major sights to see what it looks like internally and how it functions. There will be no need of a towel on this short tour. Target audience: Developers and system architects who want to get a better understanding of how their applications will run.   About Robert   Robert Virding is Pr ...

  • EUC 2014 – Garrett Smith – Why The Cool Kids Don’t Use Erlang
    2014-06-18 Erlang Central

    Videos



    Erlang is ideally suited building scalable, fault tolerant systems with minimal investment. It can be used for any conceivable application - not just telecom. It has a multi-decade track record of success. So why does it remain a niche technology? To answer this question, Garrett turned to science. He conducted a detailed survey across a wide spectrum of programmers, architects, and managers to gather data on this question. In this talk, Garrett will present his findings and reflect on what t ...

  • EUC 2014 – Torben Hoffmann – Erlang Patterns Matching Business Needs
    2014-06-16 Erlang Central

    Videos



    In this talk we will present a number of common patterns from Erlang systems and how these patterns relates to business needs. Most of the patterns revolve around the notion of how failure is handled and we will discuss how active treatment of failure leads to better options for the product owner when it comes to prioritising fixes and new features. By modelling the patterns using the newly created Visual Erlang notation we get a new way of talking about Erlang systems and architectures, which w ...

  • EUC 2014 – Katie Miller – Keynote: Composing a Functional Community
    2014-06-16 Erlang Central

    Videos



    We know the wonderful benefits of functional programming, but when it comes to sharing the lambda love we often do a poor job. In this presentation, Katie will draw on her experiences as a journalist, workshop instructor, functional programming student and women's group founder to take you back to that time before you knew what jargon such as monad meant, and offer ideas and inspiration for helping people of all kinds and categories along the path to FP enlightenment. Be warned, content may chal ...

  • EUC 2014 – Stuart Bailey – Keynote: Erlang, Open Networking, and the Future of Computing
    2014-06-13 Erlang Central

    Videos



    Erlang is poised to be at the center of a massive disruption in computer networking -- the shift from hardware-defined to software-defined systems. Stu will explore the many benefits that software-defined networks (SDN) deliver in cost, scalability and control. The emergence of SDN also raises important questions about the future of proprietary vs. open-source networking software. Stu will discuss why the Erlang community is uniquely positioned to drive the debate. ...

    2014-06-11 Erlang Central

    Videos



    Tony Rogvall is a programmer and entrepreneur who has been active for more than thirty years in the computer business. With an education (M.Sc) in mathematics and computer science, Tony's first task as the first employee at Prover Technology (www.prover.com) was to develop a ground breaking formal verification and proof system for safety critical systems in nuclear- train-, automotive- and the aviation industries. In 1993 he joined Ericsson CSLab, computer science laboratory, as a co-worker a ...

  • Continuous Migration: Reimplementing the Purchase Taking Capability of a 24/7 Financial System – Daniel Lee
    2014-06-04 Erlang Central

    Videos



    Klarna is currently undergoing a migration where its purchase taking capability is being ported from its very large, monolithic Erlang system that performs many varied business tasks to a specialized one for taking purchases using current Erlang best practices such as rebar and other standard open source offerings (lager, folsom, riak, rabbit, and more) deployed with Chef. Focal points will be how Klarna's regular weekly release cycle has allowed this to be an incremental process, as well as h ...

  • Let’s Write A Test! – Joe DeVivo
    2014-06-03 Erlang Central

    Videos



    Come with me as we walk through implementing a new feature of Riak with riak_test. We'll go through adding a feature to Riak with Test Driven Development, going into as much detail as time will allow. We won't be delving into the internals of riak_test, but rather how we use it to test Riak. Talk objectives: Attendees of this talk should leave with an understanding of how to add a feature to Riak using Test Driven Development and riak_test and how those techniques and tools might be applicabl ...

  • Building Wireless Sensor Networks, MQTT, RaspberryPi and Arduino – Zvi Avraham
    2014-06-03 Erlang Central

    Videos



    In this talk, Zvi will share his experiences in developing an MQ Telemetry Transport protocol (MQTT-S) over Zigbee Gateway software in Erlang/OTP. MQTT-S is used as a publish/subscribe messaging protocol for wireless sensor networks (WSN), with the aim of extending the MQTT protocol beyond the reach of TCP/IP infrastructure for Sensor and Actuator solutions. This makes it a very efficient protocol for Machine-to-Machine (M2M) and Internet of Things connectivity. Talk objectives: • Intro ...
