An issue that can crop up with Flex applications is the lack of any log information to match up against users' bug reports.

This post provides a simple IValueConverter implementation that makes use of the framework type converters in order to convert between a large range of source / target types. This converter can be used both within bindings and in code-behind to give more concise property setters.
UX Design
Last week I attended a series of information visualisation workshops run by Stephen Few.

UX Design

This blog post looks at a recently published set of charts in a UK newspaper and how they fail to help in the comprehension of the data which they visualise. I will also look at much more effective ways of displaying this same data.
Tech
In this post I demonstrate a method for binding a Silverlight 3 DataGrid to dynamic data, i.e. data which does not have properties that are known at design time.

This blog post demonstrates a Linq API which can be used to query the WPF / Silverlight Visual Tree.
Tech
This blog post describes a simple technique for ensuring that consumers of events unsubscribe their event handlers without the need for weak events.
Tech
Sparklines are described by their inventor, Edward Tufte, as "data-intense, design-simple, word-sized graphics".
Delivery
Last week I gave a presentation on Agile Development for an event hosted by Codeworks and Sunderland Software City.

This blog post is about my entry to the Mix10k code competition, and old-skool demo, plus a few tips about how to keep you code size to below 10k.
