But why does println not behave this way?
I think I stick to println for the moment.

there're three buffer mode in unix, line buffered, full buffered and no
buffered, if the output is terminal then it's default to line buffered.
That means it buffer the output until '\n' occurs, you can force output via
flush.

Well, I'm not very familiar with buffer in java. But I think it's always
safe to call flush if you want to see the output immediately.

I have the opportunity to build a set of services from scratch. I plan to
use clojure for this.
I'd like to experiment with options available out there - options such as -

some of your experiences in this and
I've also had a lot of success with Prismatic's

One could quantify this with Category Theory. In order to map from one
domain to another reversibly, the target domain must have at least as many
elements as the source domain, if not more. An abstraction which simplifies
by reducing the number of elements in play is guaranteed to be leaky.

Hi Tim, awesome news!. I've had other folks today asking about it as well.
Any idea how we could use a shared calendar to let people put down their

that's a Clojure project we should work on! ;-)
