We recently talked about how watching people code could be the next big thing in online video. Developer Karim Amrani believes in the trend and has built a simple tool to make it easy for coders to create tutorials in a single browser window. Codecast lets you code HTML and CSS and view the output side-by-side, negating the need to switch between your code editor of choice and your browser window. Of course, you’ll still need a tool to record your screencasts. Codecast is free and_you don’t have to register to use it.
