If you’ve been using S3 client in the AWS SDK for .Net you might have noticed that there are no methods that let you interact with the folders in a bucket. As it turns out, S3 does not support folders in the conventional sense*, everything is still a key value pair, but tools such as …
In part 4, I put together the foundations for a mini shooting game, with targets moving on the screen and you can ‘hit’ them by clicking inside the targets, etc. etc. I promised an update to make it feel more like a game, so here it is! Adding a background The black background was more …
Following on from part 3 where we basically made a little app that lets you scribble with HTML5’s canvas element, let us push on and see what else we can achieve with the canvas element. The logical next step would be to made animations, and give you a way to interact with the animation. So …
Time really does fly when you’re having fun! In a blink of the eye it’s been a whole year since I left Credit Suisse to start a career making social games with IwI. All and all, it’s been a year filled with lots of hard work, lots of learning and honestly, a hell of a …
Java vs C# As Jon Skeet pointed out in this excellent article on closures, the strategies of capturing the execution context which the behaviour is bound to different between Java and C#.

I saw this in last month’s .Net magazine and thought it was pretty cool and worthwhile sharing. Without giving away too much of the intricacies (seeing as this is not my own work), this technique essentially boils down to using Javascript to append a <span> element to mask over each of the links on the …
