Testing a mobile app is challenging, thanks to operating system fragmentation combined with diversity of hardware. In April 2013 Xamarin acquired a company called LessPainful, specialists in functional testing for mobile apps, which had created a mobile app testing tool called Calabash. Calabash is based on Cucumber, and lets you define test steps and then

Beginner’s All-Purpose Symbolic Code (BASIC) has turned fifty, as reported on The Reg and by Jack Schofield on ZDNet. A great moment in computer history, or would we have been better off without it?
My first computer (a Commodore PET) ran Basic from ROM, and without it you could do nothing, though developers bypassed it

Problem: You have a ListView containing data. You want to vary the appearance of items in the ListView according to the value of the data.
I spent some time on this in relation to a panel for a game I am writing. For example, you have a ListView containing numbers. How can you have negative

Embarcadero is spilling the beans on a new development tool called AppMethod, which has its own site here and a little more information on TechCrunch. A fuller reveal is promised at SXSW, which kicks off on March 7 in Austin, Texas.

I’m at QCon London, an annual developer conference which is among my favourites thanks to its vendor-neutral content.
One of the highlights of the first day was Tom Stuart’s talk on impossible programs. Using a series of entertaining and mostly self-referential examples, Stuart described why certain computing problems are uncomputable. He also discussed the “Halting

Microsoft has improved its browser-based Windows Phone App Studio beta and added the ability to generate Windows Store apps. The changes are described here.
First, a quick tour. App Studio is carefully described as a tool for building “content-based apps”. The personal use case is an app to show off your recent holiday, favourite band,

The QCon London conference is on in early March (5-7). It is always a conference I look forward to since it is vendor neutral, though with an agile flavour. Although it covers high scale systems it is not the place to go if you think heavyweight Enterprise middleware from a big name vendor will solve

A post by Ahmet Alp Balkan on working as a developer at Microsoft has stimulated much discussion. Balkan says he joined Microsoft 8 months ago (or two years ago if you count when he started as an intern) and tells a depressing tale (couched in odd language) of poor programming practice. Specifically:
Lack of documentation

Embarcadero has released RAD Studio XE4, its suite of development tools for Window, Web and for the first time, Apple iOS. iOS support first appeared in an earlier release, but in preview, and the current effort works using a new LLVM-based ARM compiler so is somewhat unlike the preview. Individual products such as Delphi XE4

I wanted to test an app on Surface RT this morning, though I am out of the office with just a Samsung Slate (has Visual Studio), the Surface, and hotel wi-fi.
You can do remote debugging on Surface RT as explained here, however you need a private network.
I set up an ad-hoc network from
