Four short links: 29 July 2014

Community Detection, Proven Kernel, Graph Processing on GPUs, and Browser Vision

  1. Online Community Detection for Large Complex Networks (PLosONE) — readable recount of earlier algorithms and inventions in the area, as well as a new algorithm with linear time complexity for large complex networks.
  2. sel4 — open source OS kernel (GPLv2, most userland is BSD) with end-to-end proof of implementation correctness and security enforcement. (For a discussion of what’s verified, see this blog post)
  3. mapgraph.ioMassively Parallel Graph processing on GPUs. (via Leo Meyerovich)
  4. tracking.js — browser framework and algorithms for computer vision algorithms and frameworks.
