An OpenCL backend for TensorStream
After some time I finally have an alpha version of an OpenCL backend for the TensorStream machine learning library that I have been working on for quite some time.

Glim - A new faster jekyll website compiler clone / alternative (in ruby)
Hello, Jekyll not fast enough? Why not build a compatible faster clone / alternative from scratch / zero (in ruby)? Sounds crazy? Allan Odgaard (of TextMate fame) has just done it and with about 3 000 lines of ruby code offers even more features than jekyll itself :-) e.g. built-in tags and categories for collections, lazy evaluation and parallized builds, better defaults, and much more. Find out more at the Glim website compiler source project repo. Cheers. Prost. PS: By the way - did you know? Slide Show (S9) is another jekyll-compatible clone :-) that lets you build presentations / talk slides in markdown (kramdown, really) and jekyll themes e.g. reveal.js, shower.js, bespoke.js, s6, etc.
