do.js

An experimental Javascript library that can be used for asynchronous control flow, non-determinism, parsing, and other kinds of computations which implement the interface:

bind :: m a -> (a -> m b) -> m b
return :: a -> m a

This gist is a temporary living situation for do.js, and will most likely be expanded into a full blown Github repository in the future.

A few show tricks to find slow queries in mongodb

Enable profiling

First, you have to enable profiling

> db.setProfilingLevel(1)

Now let it run for a while. It collects the slow queries ( > 100ms) into a capped collections, so queries go in and if it's full, old queries go out, so don't be surprised that it's a moving target...
