To find out if a string contains a piece of substring, here are three simple ways of going about it in C#, just to name a few: String.Contains String.IndexOf where the return value is >= 0 Regex.IsMatch Out of curiosity I wanted to see if there was any no[...]

Problem A. Speaking in Tongues The problem is here.   Problem B. Dancing with the Googlers The problem is here.   Problem C. Recycled Numbers The problem is here.   Enjoy!

I found out about Google CodeJam the other day, and looking at their info page, there’s a number of interesting problems you can solve as practice for the real thing coming up, and here are my F# solutions to the qualification round questions from the 201[...]

One of the problems with using F#’s Discriminated Unions is that they are not extensible, in that all your union cases must be specified inside one Discriminated Union (abbreviated to DU from this point) type and you can’t inherit from an existing DU type[...]

I love using F#’s Record and Discriminated Union types, they work nicely with pattern matching inside your F# code and can often alleviate some of the ceremony involved around creating and using a complex object hierarchy. However, on the odd occasion whe[...]

The first stable release of the Silverlight 5 Multi-Window Controls project is now available on CodePlex which brings external window support to the ChildWindow and ContextMenu. So what’s next if anything? I came across Tim Heur’s Silverlight Floatable[...]

Note: don’t forget to check out the Benchmarks page to see the latest round up of binary and JSON serializers.   Since my last round of benchmarks on binary serializers, there’s a new player in town – MessageShark, which at the time of this writing does n[...]

For illustration purposes only, here’s how you can implement the QuickSort algorithm in a few lines of code: Note that I’ve not made the list generic to avoid complications and performance overheads associated with dealing with generics. Even then, my 5-l[...]

Silverlight has become increasingly popular for applications that run both in-browser and on the desktop like Sky’s Go. One of the key new features in Silverlight 5 is multiple window support for desktop applications (often referred to as Out-of-Browser ([...]

A ChildWindow in Silverlight is a control that can be displayed over a parent window blocking its interaction. Silverlight 5 introduces multiple window support for Out-of-Browser (OOB) applications with elevated trust. Unfortunately the ChildWindow contro[...]
