I’ve been working on a new as-fast-as-possible platform for a specific situation I can’t go in to right now but I wanted to use MongoDB, however, I needed to reduce costs and use AWS so I wanted to use DocumentDB and needed to compare.

I just got my certificate through from Coursera for completing the Heterogeneous Parallel Programming by University of Illinois at Urbana-Champaign on Coursera and I’m very happy! It was a fun (and free) course that covered primarily CUDA programming but towards the end went on to OpenCL. Fun course to do and really helped me rethink parallel … Read More “Heterogeneous Parallel Programming – Completed and Certified!” »
Over the last few days I’ve been working on interfaces to use across multiple programming languages to standardise how some things are done. This stemmed from a requirement to allow processing to be dealt with in any language from any other language.

One of the first things I wanted to do was created custom modules so I could organise my code clearly. I found a surprising lack … Read More “phantomjs custom module – require and create” »

Coming from a PHP background, I love the PDO function fetchObject(), it’s just right there and you get … Read More “C# MySqlDataReader – “one line” function to return a row as an instance of a class.” »
