  • Isometric Game Test

    Over the weekend I managed to take some WebGL libraries (ThreeJS, BabylonJS) for a spin, and made a little demo reminiscent of isometric RPG-style games. Sadly you can only walk around with the WASD keys at the moment, and I still have to implement proper movement and any sort of collision detection. But playing around with the libraries was fun! I started with ThreeJS but ran into problems with its shadowing fairly quickly (shadows turn everything completely black even with other lights present). Also the public Github repo has loads of unmerged open PR’s, so I looked for alternatives. I came across BabylonJS which I’ve liked a lot, you can see the results in the demo.

    The map is defined as square of symbols in text format, where the different types of objects are identified by letter (P for Pillar) and a number for rotation (1 for 90 degrees, 2 for 180, etc). It uses inbuilt primitives such as Cubes, Cylinders as well as custom modeled objects in OBJ format. I’ve also downloaded the model and walkcycle from the BabylonJS playground website.

    I’ve had some issues with loading custom OBJ files, especially handling the asynchronous loading. Also the fact that you can only have a maximum number of 4 lights active is a bit sobering, but I suppose I shouldn’t expect full blown rendering capabilities which I’m used to from Maya, Renderman, etc. Anyway, it’s been a lot of fun, will see how much further I get with it.

  • CodeBar

    I went to my first CodeBar session! codebar.io is a great non-for-profit organisation that aims to teach “underrepresented groups to learn programming in a safe and collaborative environment”. The events are run as weekly workshops where tutors meet with students to work on a set of tutorials or their own projects. This event was organised by Tatiana Soukiassian who works as a developer at GDS. I initially only volunteered for setting up the venue and showing people to the right floor, but by the end it turned out that two people still needed a tutor for an introduction to HTML. So I spent the next 2 hours helping out by going through the tutorials with them. We even branched out a bit and had a quick look at using Bootstrap. I found it really rewarding and enjoyable, would definitely recommend for anyone to get involved!

  • Property Prices UK

    I wrote a Rails app to display property prices in the UK over the last 10 years (2006-2015), based on data from the Land Registry. Written with Rails, BootStrap, ChartJS, hosted on Heroku. Inspired by a coding test at a start up I took a while ago. Planning to add a paginated listing of the individual sales as well as a breakdown by type of property.


  • Happy New Year!

    I’ve rewritten the website with Jekyll. I stumbled across this nifty website generator recently updating physio-an-der-bucht.de and have come to appreciate the general file structuring and reuse of components. It allows for easy blog updates also.

    So I’ve taken the time to update my site, mainly to reduce some old clutter (removing 2 different places for blog style updates) and updating some of the content. Ideally I would still like to have a live editor similar to WordPress, but this will do nicely until I get time to investigate more.

  • Parliament Visit

    Today, the e-petitions team from Unboxed was given a tour through Parliament, ending with a vist at the Lords’ bar! We finished work on e-petitions for Government Digital Services in June/July and it’s been widely used since the the relaunch. So on Friday we toured the House of Commons and House of Lords and heard some of the interesting backstory to the UK’s parliament.
