Posted by gamlerhart in .NET, software-development on June 30, 2010
Sometimes small changes make have a large impact. An example is the exception-handling difference of Delegate.BeginInvoke and ThreadPool.QueueUserWorkItem. I’m working on a WPF-client application, which does quite a lot of work in the background. Most of the background work is handled by a special task coordination class.

I’m currently extending the dSail System-software. The idea is to provide real-time data about the air flow on a sailing boat. This information can help you tweaking the sail position to reach the highest speed possible. In order to get this data sensor-nodes are attached to the sail. Each node has multiple sensors, like pressure, [...]
