Today I recorded my fifth Slingcode screencast about making apps in Slingcode using the Hyperapp library. It's a minimal user interface library for building web apps, and it works really nicely with the Slingcode workflow. You can get a basic app up and running incredibly fast.
These screencasts have been going pretty well with more than 100 views on each one now, and the developer audience on YouTube seems to be getting value out of them which is very gratifying.
I also made a single page on the slingcode site with all the screencasts listed so there is a single point of reference.
