Our stuff is already on it’s way to Toronto! By boat. Hope my books don’t get seasick.

I’ve decided to spend my time on more useful things than learning historic programming languages like Lisp. (Although that was a lot of fun and it definitely changed my thinking and coding style in a positive way!)
My goal for the coming months is to master Open Solaris. What I want to learn is a good […]

% dd if=/dev/zero of=data bs=1 count=2679
% sha256sum data

A file of 2679 zeros and its SHA-256 hash. Nothing special.
Well, not exactly .. now look at the equivalent Python code:
