It really slims down the overbearing ideas of software development… View full post »

VPS.NET Review - One Year Later

We’ve been hosting Learncomputer.com on VPS.NET for slightly over a year now, and I wanted to share my experience with this provider, as well as compare it with our previous web host, HostGator.

How HTML5 Improves the Semantic Web

For some time, web designers and developers have been talking about the “semantic web”. Ever since table based design went out the window, there has been an emphasis on using CSS to create semantic class names to mark up elements in a way that described the content and not the presentation.
