I don't know how many times I've put together the same slow regexp to check if the user input is a valid phone number. I decided that this cannot go on and developed a simple phone number primitive. Now our main concern here is the performance of TryParse since it will be used the most. After running some performance tests the median timing was 400ns on a 3Ghz machine.

Microsoft detailed its support for a number of HTML5 specifications, including CSS3, Scalable Vector Graphics (SVG), XHTML parsing, and the video and audio tags using industry-standard (H.264/MPEG4 and MP3/AAC) codecs, among others. In addition, Microsoft demonstrated a new JavaScript engine that uses the multiple cores of today’s modern chips to effectively manage computing resources and improve Web performan...

Yesterday I made a post about using a queue instead of a list because the code was so much cleaner. I think it is very important that code is clean and easier to read.

But then Denis asked about the performance differences between the 2 methods. I hadn't worried about the performance, because in my case the performance was good in both cases.

But I aim to please my fellow LTDers, so I did a little performance test. And let me remind you that like most performance tests, this one ...

I was doing this in my code.

Visual Studio 2010 and .NET 4.0 are almost released, one of the new things that ship with this release is Parallel Programming. Since you can't buy a machine anymore with just one core it is time that we developers get intimate with concurrent programming. I decided to play around with this a little today, this is not a real technical post, I mostly show you how you can get started and what new tools are available.

The best way to learn about new additions to a framework is to look at some code. There are 22 sam...
