• Valuable and Consistent Commit Messages

  In order to provide valuable and consistent commit messages we follow the “imperative present tense” style for commit messages. Write the commit message as “Fix bug” and not “Fixed bug” or “Fixes bug”. This convention matches commit messages generated by commands like git merge and git revert.

• Chain of Responsibility Pattern in Scala

  When implementing some custom directives in Spray to handle pagination and sorting, it occured to me that the handling of the pagination and sorting might be applied nicely to a Chain of Responsibility design pattern as this would allow me to encapsulate different operations and allow them to be used together or in isolation, or with other, newer operations.

• Harold

  Ages ago I made a little Arduino hack which was a simple LED matrix with three faces; happy, neutral, and sad. I recently found a photo of it so thought I’d post it. It was called Harold. I’d like to say it stood for Helpful Assistant Redisplaying OnLine Data but in truth I just like the name Harold. :)

• BBC Radio Tree v2.0

  BBC Radio Tree is a Christmas tree you can tweet! The tree lives at @bbcradiotree on Twitter although in real life it lives in BBC New Broadcasting House in the Radio 1/1Xtra production offices. BBC Radio Tree will change colour depending on the hashtags you tweet and it will send you a selfie back to show you your awesome colour scheme!

• Build Blog (BBC Radio Tree v 2.0)

  BBC Radio Tree is a Christmas tree which can be controlled by sending colours to it via Twitter. The tree will then respond by changing colour and notify the tweeter. For 2015 I decided to upgrade 2014’s BBC Radio Tree v1.0 which had three colours to a new build which uses 256-colour, individually-addressable NeoPixel LEDs in a custom array. This is the build blog of the 2015 build.

• Simple Homopolar Motor

  A homopolar motor is a direct current electric motor with two magnetic poles, the conductors of which always cut unidirectional lines of magnetic flux by rotating a conductor around a fixed axis so that the conductor is at right angles to a static magnetic field.

• Genetic Algorithm in Scala

  Genetic Scala is a basic genetic algorithm implementation in Scala. The solution to achieve is a 64 bit number which is entered as the candidate solution. The fitness of each organism is it’s closeness to this 64-bit number and the process completes when an organism’s chromosome matches this solution.
