Development

We have an Angular.JS application which is also using Bootstrap for its layout, and we’ve come across an irritating layout bug on IE7 (for which the client still has a requirement – albeit with a “please upgrade your browser if you can” notice). Supporting IE7 with any modern web framework is a bit of a […]


In the last section, we set a couple of problems, and asked you to devise a program to come up with the answer. A. Write a program to add up the integers from 1 to 10, and put the result in to the memory location at offset zero. B. Alter the program to add up […]


Android Device Manager and SDK Location

by Pascal Arnould

After going through the Xamarin installation instructions for Mac and Windows , I ended up in a situation where the AVD Manager ( Android Virtual Device Manager ) on my Windows VM would not let me create a new AVD […]


In the last section, we looked at an imaginary computer architecture. In this section, we’ll step through our first program from beginning to end, to see what it does. Then we’ll actually run it on a computer! We’ll start out by investigating the program instruction memory. Program instructions and the program counter You can think […]


A short explanation of Windows Phone capabilities and how to enable the camera […]


In the previous posts I’ve explained how to set up installers in your application, how to use the content factory, and how to set up the composition framework for ASP.NET. In this post I will show you how to debug the container. If you try to resolve a component that has missing dependencies, the Container will […]


It’s time for another block diagram. Most modern digital computers are organized something like this: We call this the Harvard Architecture. When we talk about architecture in computing, we mean a high-level view of the parts of a system, and how they relate to one another. How does it work? The Control Unit is, as […]


Windows Phone Registration Failure: Error 0x64

by Pascal Arnould

A quick fix to error 0x64 when registering a new Windows Phone device […]


To use endjin composition framework with an ASP.NET MVC 4/WebAPI application, firstly pull in the Endjin.Core.Composition.Web package from NuGet. Following the steps from the previous posts, you can set up your interfaces, concrete types and installers. No further initialization is required though – the package includes extensions for configuring and initializing the container, and also […]


How does a computer work? This is quite an interesting problem. It is rather similar to the question “How long is Britain’s coastline?” – it depends how closely you look (1). How does a computer work (I) – the end user perspective As an end user, I might say “I make sure it has got […]


Windows Run Commands for Developers

by Pascal Arnould

The other day I wanted to bring up the Windows “Program and Features” panel using the run command (Win+R or just start typing in the Start screen in Win 8). Something I’ve done countless number of times in the past. For some reason, I had a complete blank and couldn’t recall what that particular command was. So I thought it would be good to have a couple of tips and some of the most useful run commands for Developers (and everybody else) in one place […]


As I explained in this post, the framework provides a set of installers for registering components against interfaces in the container. Another powerful tool in the composition framework is the ContentFactory. This provides methods for registering and getting content based on a contentType string. When getting content, if the contentType is not found in the […]


In this world, we have to face up to the horrible possibility of failure. Sometimes, that failure is irrecoverable. There’s no going back. Sometimes, we can have another bash at it and see if it comes out OK the second time around. Or maybe the third. Or the fourth. In the software business, historically, we’ve […]


In part two of this series, we’re going to get set up with an environment in which we can execute code. If you’re running a version of Windows on your desktop/laptop, then this is the post for you. If you’re running a version of Linux on your desktop/laptop, then this is the one you need. […]


Getting set up on Windows You need to be running Windows 7 or Windows 8 (or later). If you’re running Windows Vista or Windows XP, I’m sorry, but this isn’t going to work for you. First, we need to make sure that the .NET Framework V4.5 is installed. If you happen to have installed Visual […]


Getting set up on Linux Installing on Linux is a bit more complicated than installing on Windows. I’m assuming that if you’ve opted for Linux, you’ve got a bit more technical experience. I hope so, or some of this is going to be a bit confusing! I’ve used Ubuntu Linux 12.10 in a default desktop […]


Xamarin platform setup gotchas

by Pascal Arnould

Yesterday I attended the “C# and Mvvm – Developing apps for all of Android, iPhone and Windows” event hosted by Stuart Lodge at Modern Jago. In preparation for the day I had the daunting task of setting up my Mac (OS X 10.8) for cross platform development with Xamarin. While most of it was fairly straight forward and well documented (see Installing Xamarin.iOS), I came across a few gotchas worth blogging about.


In the last post I introduced v2.0 of our open source, composition framework. In this post, I’m going to cover a quick example of how to get started with the basics of the endjin composition framework. Firstly, we define an interface for some type Then, we create a concrete type for our interface Now we can […]


Introduction Programming, like most crafts, is the process of taking one thing and turning it into another thing. Turn a touch on a screen into a character in a message, or a tap on controller into the sideways shuffle of a character in a game. Simple to describe, they’re actually quite complicated to achieve, involving […]


We’ve just pushed out version 2.0 of our open-source, component composition framework. This is the framework we use internally day-in, day-out for our dependency injection. The previous version had a dependency on Castle Windsor, but in this new version we have implemented our own container. There are a few reasons we decided to take this […]
