Some days ago I had the opportunity to do a spike on making a small application and deploy it in App Harbor. I had never used App Harbor before, but I had used Heroku, which is another “Platform as a Service” (PaaS). Heroku is very easy to get started with and it’s easy to deploy [...]

Team .NET Web was represented by Gustaf (@gustaf_nk), Per (@per_okvist) and Karl (@herradriansson), with a session about our views on [...]

For a little while now, I’ve been playing with Sammy.js, a small framework built on top of jQuery which makes it easier for you to develop single-page web apps.
