I was looking through some code the other day and ran across something that looked remotely familiar. It was the null coalescing (??) operator. I had read about this operator, but never used it. It was introduced with the .NET 2.0 Framework. The null coalescing operator basically checks to see if a value is null and if so returns an alternate value. Below is a simple example. C# Code Listing using System; namespace...

The jQuery Javascript library has gotten a significant amount of attention from Microsoft developers this year in large part to its nice fit with the new ASP.NET MVC framework. I myself was totally new to jQuery and I started using it with MVC because I wanted to see what the big deal was. Sure enough, I became a true believer like many others. And I found myself suddenly having "JavaScript envy" because I couldn't do all the...
When it comes to proper usage of CSS and HTML layout, I have to admit I’ve been somewhat slow to get up to speed. Although I’ve been fully aware of what ‘you’re supposed to be doing’ it’s been quite a different story from what I’ve actually been doing. Part of it is that a lot of the apps I work on are based on older code that didn’t pay close attention to CSS based layout and so it’s often hard to retrofit those apps. But slowly and gradually...

Earlier this year I posted a port of the CSS minifier from YUI Compressor, Yahoo's java-based library that reduces CSS and JavaScript resources with a measurable advantage over other similar tools. I made plans to port the JavaScript compressor as well, which is known for its ability to rename inner function variables, but could not find the time, as the task would involve porting the entire JavaScript parser used to decompile the JavaScript and...
