Pathfinder using DirectX and Genetic Algorithms

Well, I’ve been threatening it for long enough, now it’s time for some action : ) Over the course of the next few weeks I’ll aim to build a simple 2D application that demonstrates how a Pathfinder application can be developed using genetic algorithm’s. I’m going to use DirectX to render the 2D display because…

Silverlight 2 Book – Go Buy It!

OK, so it’s finally finished. It’s been a long time in the making and has consumed all of my spare time, so please go out and buy a copy. Judging by its dimensions it will make an excellent door stop, table leg prop, paper weight or of course Silverlight 2 guide. http://www.amazon.co.uk/s/ref=nb_ss_b?url=search-alias%3Dstripbooks&field-keywords=silverlight+2+for+asp.net+developers Get ready for…

Silverlight 2.0 For ASP.NET Developers

The more astute of you may have noticed that my blog has been a little ‘sparse’ over the past year or so. In fact, I still have a couple of half finished articles that I promised some time ago (Path Finder example using Genetic Algorithms springs to mind). The good news is I have a…

Composite WPF/Prism

So this week I’ve been involved in a workshop with the P & P team in Redmond evaluating and discussing ideas around Composite WPF and what deliverables might look like in this area. It’s been very useful indeed, with some great feedback from the other delegates around what people liked/disliked about the CAB and SCSF…

The primary goals of the engagement were: ·         Better understand the P&P offerings and future direction ·         Ascertain the best approach to building and reusing application frameworks across an Enterprise. ·         Develop a…

Genetic Algorithms Basics

So.. I’ve finally got around to blogging about Genetic Algorithms, apologies it’s taken me so long. I’ll kick off with a very brief tutorial around the theory behind genetic algorithms, before moving on to a concrete example showing how to solve the Path Finder problem in my next post. It’s not an easy topic, but…

P & P Workshop, Redmond

Hi all, I write this blog post from the comforts of the SAS lounge in Copenhagen airport, whilst I wait for my connecting flight to Seattle. The joys of a long haul flight await, let’s hope Alastair Reynolds book “Absolution Gap” keeps me occupied.                                                                                                             So… this post is just to set the scene for…

Customer Care Framework

I’ve been in Redmond all week checking out CCF with the product group. Some of my clients are looking at utilising its features and so I’m busy getting the lowdown on the CCF roadmap etc. Not many people tend to have heard about it and its capabilities and so expect a blog post imminently with…

.NET Interop – Freeing unmanaged memory

OK. Imagine you need to call an unmanaged function. Now imagine this function returns you a pointer to a block of unmanaged memory that it’s allocated. The runtime will clear this up for you right? Wrong. Well, wrong a lot of the time anyway. The runtime always attempts to free unmanaged memory using the COM…
