  • Building Interactive Displays with Touchscreen 2.0

    by Rob McGuire-Dale and Peter Krenesky

    Touchscreen is a platform for creating interactive kiosk and dashboard displays. Its built with well known technologies making it easy to create custom content for your own display.

    Touchscreen 2.0 powers presentations about the Open Source Lab's data center and the network operations center. It provides our admins and our visitors with graphical representations of real-time data about our network operations.

    Come Learn about:
    * What touchscreen is, and what it can do for you.
    * How version 2.0 was built (and our successes and failures along the way)
    * How to implement content plugins for touchscreen including:
    ** Using Raphael and SVG for graphics and animation
    ** How to quickly mash up content sources with jquery

  • import rdma: Zero-copy networking with RDMA and Python

    by Andy Grover

    When the computer receives a packet, it is copied into a kernel buffer by the NIC, then copied by the CPU from the kernel buffer to its actual destination in the receiving process's address space. The same data is transferred over the memory bus THREE times, and the CPU must dumbly read and then write every single byte, even before the application sees it.

    RDMA (Remote Direct Memory Access) lets processes on different machines send data directly into each other's process spaces, resulting in greatly increased efficiency. But, using RDMA is very hard, compared to BSD sockets. This talk will introduce my work on making RDMA usable by mere mortals, from Python!
