This blog post presents the result of analysing 250,000 screenshots from the Apple App Store, looking at hue, lightness and saturation histograms for each category.

The App Store continues its rapid growth, with approximately 300,000 apps added each year. I decided it would be fun to download as much app metadata as possible in order to see what patterns and trends I could find. This blog post describes the results.

This blog post looks at how to simulate accelerometer and location data so that you can test iOS apps without the need for a physical device. The simulated data is provided by an interactive UI which allows you to rotate the phone and mark paths on a map which can then be replayed.

It feels like everyone in the iOS community is talking about ReactiveCocoa at the moment. In this blog post I talk briefly about what ReactiveCocoa is and the 'Definitive Guide' which I wrote for raywenderlich.com

Recently, I have been starting to get to grips with WebGL. Having little to no real previous experience with 3D graphics, there was a reasonably steep learning curve to overcome. So I thought I'd touch on a few of the basics here and share some resources that I found really useful.

It's easy to get started building data-bound user interfaces in the browser using the KnockoutJS MVVM library. This post covers some practices and techniques that help with using it successfully in large single page applications.

Recently, Knockout's original author Steve Sanderson released a plugin called knockout-projections which optimises the performance of the observable array methods filter and map.

PropertyCross has just announced a v1.3 release, which includes two new frameworks, a number of updates and an improved build system.

When moving back from web to desktop development, it's easy to miss the quick feedback and update cycle enabled by the developer tools in modern web browsers. To an extent the debugger intermediate window does many of the things the console allows, and many of the "script debugging" features the browser provides are based on a traditional debugger. However the display of the page DOM and related CSS properties, and the ability to inspect and manipulate these on the fly to debug and develop a design, is something that it feels hard to live without.

The recent rise of web applications that have all the functionality of their desktop counterparts has highlighted the fact that JavaScript MVC Frameworks are now an essential part of any modern web developers toolkit.

Suppose you have a collection, and you need to perform an action on each element. That's not hard to do in any mainstream programming language. What if you need to know the index of each element as you process it? Not hard, but depending on your datastructures, possibly not as straightforward as it first sounds.

This blog post looks at creating an interactive tab bar controller transition, where you can swipe left and right to navigate between the tabs. The transition itself is a 'paperfold' effect - very pretty!
