  • Of Heisenberg and Hawthorne: Measurement, Visibility and Guidance
    2013-06-13 Erlang Central

    Presentations Videos

    Being successful as a company probably means that you are doing the right thing, but it does not necessarily mean that you are doing things right.  From a technical point of view, you are sitting with a growing technical debt that will slow you down in the long despite adding more developers.  This can be turned around, by focusing on long term quality (by knowing what you are actually testing) and productivity, raising awareness of technical debt by measurements and visualisation and providin ...

  • Active Queue Management – What it is, and why you should care
    2013-06-13 Erlang Central

    Presentations Videos



    Peak load, and burst-y traffic are problem spaces which are often (and tragically) confused for each other, invariably to the detriment of both ops and users.  While peak-load is all about capacity management, in a burst-y situation, you might have to prioritize - or even drop! - requests.  Knowing which requests to process, and how to actually process them is the world of Active Queue Management (AQM). While AQM has long been exclusively in the domain of the TCP/IP crowd, it has been slowly m ...

  • JIT, A Maze of Twisty Little Traces
    2013-06-13 Erlang Central

    Presentations Videos



    You are in a maze of twisty little traces, all alike. Last year at EUC I gave an in-depth tour of how automated source-to-source transformations were used to generate a proof-of-concept JIT compiler from the VM sources. Since then work has progressed to turn the proof-of-concept into a prototype. Turning a proof-of-concept into a prototype is a process with many degrees of freedom, not unlike an old-school adventure game where you start out with minimal knowledge of your surroundings and ...

  • Building Wireless Sensor Networks with Erlang, MQTT, RaspberryPi and Arduino
    2013-06-13 Erlang Central

    Presentations 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: •    I ...

  • Scaling Web Development: an Erlang Widget Platform
    2013-06-13 Erlang Central

    Presentations Videos



    In order to get the control of our websites, at Spilgames we decided to create a platform to ease the development process. The platform contains versioned widgets that get combined for building webpages. It also includes simple web tools for deploying and rolling them back and a native support for A/B testing. Our mission is keeping full control of what happens in our portals while being able to just increase the number of developers for getting more traction in our web projects. Talk objecti ...

  • Handling Unicode
    2013-06-13 Erlang Central

    All Blog Presentations



    Handling Unicode in your program and encoding data properly for communication with the world outside is for many programmers a new area. Thinking about the way your strings are encoded when stored in a disk file or sent over the internet has previously been a no-brainer as all characters fit in one byte. A text file was a text file and a string could be encoded in a binary without hesitation. Now days you have to think about character representation, ways of telling other programs how characters ...

  • Building RiakCS on Riak
    2013-06-13 Erlang Central

    Presentations Videos



    Riak CS is an Erlang application that exposes the S3 API on top of Riak: an eventually consistent fault-tolerant distributed key-value store. Riak CS design faced many challenges: supporting large files, distributed garbage collection and quick time to market. We'll dive into implementation details and lessons applicable to anyone building distributed systems, such as the power of immutability in large-scale system design. Time will also be given to less obviously exciting issues like versioning ...

  • Full Metal Erlang
    2013-06-13 Erlang Central

    Presentations Videos

    This talk will describe the port of Erlang to RTEMS. RTEMS is a open-source hard-realtime operating system for small embedded systems. It is used in the aerospace industry flying on satellites and planetary probes - currently its also driving around on Mars and on the Gallileo Satellites. Porting Erlang to RTEMS opens the way to new application areas, like in the current use case a intelligent RFID system for Industry 4.0 and Internet of Things applications. Talk objectives: Give a short ove ...

  • Making our Traffic Jams Disappear
    2013-06-13 Erlang Central

    Presentations Videos

    My talk presents results from the FP7 Project MODUM that are developed in Erlang. The European project develops a new approach for the pro-active demand-responsive management of traffic (cf.modum-project.eu). The developments focus on solutions assuming a high degree of participation by intelligent users. These users have an e-butler (i-butler when bought from Apple) that proactively manages their commuting and other displacements. Initial deployment of the developments will enable full utili ...

  • Erlang, Designed for the New Web Challenges
    2013-06-13 Erlang Central

    Presentations



    While a lot of frameworks exist or are created to help you build web services for today, little embrace the new paradigms that design what the web will be tomorrow. OTP has a lot and seems designed from the ground to answer to these new challenges despite its age. This talk will present a new way of building web services by using Erlang and OTP to create a gateway or a thin layer between client applications and backends with the help of webrtc and websockets standards. Talk objectives:  ...

  • Exosense – Demonstrating a Connected Device Application
    2013-06-13 Erlang Central

    Presentations Videos

    Feuerlabs' Exosense, a modern framework for managing connected devices, is now operational and has been demonstrated in a number of prototypes. In this talk, we will describe our approach to Connected Device life-cycle management, and walk through an Erlang-based embedded application for in-vehicle performance monitoring. We will make the case that a reasonably competent programmer can produce a working end-to-end demonstration within a few days, and be well prepared for rapid deployment, suppor ...

  • Relx, A Dead Simple, Robust Way to build Releases
    2013-06-13 Erlang Central

    Presentations Videos



    Building Releases is harder then it needs to be. There is already so much useful metadata in any Erlang release that it should be a simple one line command to create almost any Release. With Relcool it is. Providing both a simple command line and intuitive integration with Rebar, Relcool makes the standard Releases simple and hard Releases easy. Talk objectives: The ultimate goal is to get more people using standard OTP Releases for their systems. By introducing Relcool and showing how easy ...
