Desert Spring-Time
Me and my friend are writing an OS. Plan is to have most of it done in OCaml. I stole a simple network driver and am writing the network stack in OCaml.
I have never been so productive in my life. Here is what svn log says about my progress:

• Monday-Tuesday - Getting network driver to work
• Tuesday - Network driver is alive
• Wednesday - ARP replies work
• Thursday - ping works
• Friday - I took a break for New Year
• Saturday - UDP packets can be sent out
• Sunday - DHCP negotiation works

Conclusion: coding in a functional language is addictive. It's way too much fun.

Functional Programming
joolean you are thinking of currying. I don't know much Scheme, but you can emulate currying. Here is a curry routine for JavaScript.

function curry(fun, param) {
  function n(param2) {
   return fun(param,param2)
  }
  return n;
}

iRATE
I implemented a similarity-search plugin for iRATE. With a correctly configured plugin one can pick any song and discover music that sounds similar. Unfortunately, most users find following installation instructions tiring and end up with a non-working plugin. I have to address that issue.
I wish users would just do the Right Thing(tm).
