Engineering Virality, App Store Numbers, App Store Data, and FPGA OS

  1. How To Make That One Thing Go Viral (Slideshare) — excellent points about headline writing (takes 25 to find the one that works), shareability (your audience has to click and share, then it’s whether THEIR audience clicks on it), and A/B testing (they talk about what they learned doing it ruthlessly).
  2. A More Complete Picture of the iTunes Economy — $12B/yr gross revenue through it, costs about $3.5B/yr to operate, revenue has grown at a ~35% compounded rate over last four years, non-app media 2/3 sales but growing slower than app sales. Lots of graphs!
  3. Visualizing the iOS App Store — interactive exploration of app store sales data.
  4. BORPHan Operating System designed for FPGA-based reconfigurable computers. It is an extended version of the Linux kernel that handles FPGAs as if they were CPUs. BORPH introduces the concept of a ‘hardware process’, which is a hardware design that runs on an FPGA but behaves just like a normal user program. The BORPH kernel provides standard system services, such as file system access to hardware processes, allowing them to communicate with the rest of the system easily and systematically. The name is an acronym for “Berkeley Operating system for ReProgrammable Hardware”.

    Interested to better understand how BORPH fits into this ecosystem. Looking at this a few years ago one of the things that stood out was the absence of open source tool chains for the FFPGA’s themselves. As I recall the tool chains were all built by the chip manufacturers and none of them were making them open source.
