Frontend centric free hosting at Github

While struggling to find a decent hosting for toy projects I stumbled upon a completely free solution – Github Pages. It is feasible to think of Github as a free and scalable hosting platform for… ClojureScript powered web apps (or any other JavaScript centric one)! As stated by company employee, Github Pages service has no traffic limits (however some files used by XXX sites were banned due to JavaScript hotlinking).

One of the least known features offered by Github is hosting of static html pages with support of Jekyll static content generator. Well, at least I’ve found out about it very recently. Pages can be attached to the user domain (username.github.com) or to each of the user’s repositories (username.github.com/repository). A custom domain may also be used.

I’ve recently managed to write my first serious instrument in Overtone. It is a straightforward translation from the existing SuperCollider code. Good analysis of this synth can be found here.

Sampled piano over WIFI

Recently, after playing a bit with the Overtone project I had this idea to make a small toy application that enables to play the piano on phone and make the actual sound come from proper computer speakers. Here is the incredibly small Clojure code for the server:

Final method arguments

Among the many Checktyle rules there is this particular one (FinalParameters) stating that all method parameters should be declared as final in method implementations. This requirement might seem unnecessary or even silly but it is there not without a reason. An obedience to the rule might be observed in some open source projects so go ahead and see how it works in practice.

Namespaces survival kit

When learning Clojure there are so many interesting things to get your hands on that you forget to master the basics. It happened to me with the namespaces. In this post I’ll try to revise the API for operating namespaces and show some useful techniques.

Run ClojureScript One from Eclipse

ClojureScript is an exciting project which allows you to write your browser JavaScript code in Clojure. ClojureScript One is a sample project of a web app which is written entirely in Clojure(server, client and… communication protocol :). Recently I wanted to play with this sample app in Eclipse using CCW plugin. I realised that I could launch the dev server but somehow JavaScript couldn’t be compiled properly and I got a bogus error “Can’t recur here” from the ClojureScript compiler.
