If you’ve wanted to code your next Node.js app in CoffeeScript then it ain’t that hard. Since coffeescript is just a little language that compiles down to javascript it is pretty much compatible with node.js. Let’s take a look at some of the ways in which you can execute your node.js script (written in coffeescript).

Few days ago, I wrote a post about why time based animations are better than frame based animations. However, in animations done as a function of time, some serious problems could arise. One of them is that your regular collision detection techniques might fail if the frame rate is lower than acceptable. Your object might pass through the walls or even fall through the floor!
I am going to share a neat little trick that was learnt while working on an HTML5 game recently. The game is pretty much like our HTML5 Doodle Jump. We had to make sure that the game scales down very well on smaller devices like mobiles, ipads, tablets, etc. and in the process learnt a neat trick to scale the entire canvas across all devices consistently.

So you got into Web Based Animations or Games (using that HTML5 thingie) and chances are high that you’re relying on setInterval, setTimeout or even better – requestAnimationFrame to reflow and repaint your frames (fancy terms for rendering each animation frame). Precisely, you’re basing your animations or game mechanics on the frame rate. There’s nothing wrong with that, but let me show you a more sophisticated approach which can actually enhance all sorts of user experience – time based animations.

Recently I have been working on a project where a user can change some values inside a UI widget via form elements like input fields, range, etc. that would in turn change CSS code inside a CodeMirror editor which would reflect changes inside an iframe sandbox (like cssdeck, jsfiddle, etc.).
