The problem with writing defensive fail early code, it doesn’t take long before methods are 70% argument checking, 30% logic: [code language=”csharp”] public void Method(object arg1, object arg2) { if (arg1 == null) { throw new ArgumentNullException("arg1"); } if (arg2 == null) { throw new ArgumentNullException("arg2");</div> } … … … } [/code] Code contracts can…
When was the last time you updated your blog? Have you done anything lately that was worth blogging about? These are all questions that have been rattling around my head recently. I’ve experienced it myself, I’ve seen it via my colleagues. When people are working on interesting stuff, focused on solving clearly defined business goals,…
I’m trying to start up on project Euler again, one thing I do like is that it highlights how poor some of my maths knowledge actually is. Neither school or college covered many of these algorithms; which is a bit of a surprise given that I did a four-year mechanical apprenticeship with applied mathematics…..still never…
Just a word of warning: Windows NT and Windows Server 2003 do not support .NET 4.5 – you can not install the framework onto these systems. So if you are building in visual studio 2012 and have to support Server 2003 (or earlier) then you must remember to target .NET4.0 (or lower) in your project(s)…
One thing I’ve found over time is you can never find licensing details for VS and SQL products when you need them, so here’s the link for VS2012 Licensing details I quite like what Microsoft is doing with these white papers, the use case examples are really useful and answer most usage questions.
I’ve started playing with the JavaScript SVG library RaphaelJS. It looks a really nice library but the very first hurdle I came across was how to set the background colour of the paper. There didn’t seem to be any help in the documentation and trying ‘paper.attr(“fill”, “#f00”);’ resulted in the error Uncaught TypeError: Object #<a>…
Following on from my original post of learning how to put JavaScript together it’s been a really productive week. Have I managed to write JavaScript that’s easy to test? No, but I’ve wrapped up some reasonably complex logic into a component that can have some of its functionality tested! At the moment I’ve settled on…
If you’re using WIX and you’re adding components to the product file by hand then you’ve probably found yourself creating and cutting/pasting a lot of GUIDs which can be a real pain and productivity killer. There is the “Create GUID” menu option under tools but that still requires calling and then cutting / pasting. The…
After many years of trial and error / practise I feel fairly happy that I can write clean, testable .NET / C# code, which is free of any external dependencies which traditionally make unit testing harder. It’s fair to say that I’m a convert to TDD; having implemented it on two separate commercial projects and…
As part of responsive design a web page should react to the device it is being displayed on and make the most of the available screen real estate accordingly. With the advent of HTML5 & CSS3 the media tag for stylesheet links has been extended to cope with minimum screen heights and widths. It has…
