One of my mentors, Greg Chesson, would have loved that.  In fact, I have a
lot of friends that will love that.  Thanks for the link.

And if you are a systems guy and need more systems guys, I would hire the
author in a heartbeat.  My kinda guy.

This is an outstanding hack.  So creative.  SW bloat is such a problem.
It’s nice to see a minimalistic view — What do I really need to do the job
- ie reminds me of John Mashey’s old “Small is Beautiful” ACM lectures.

Thanks for passing it along.

Thanks!

I always also loved the obfuscated C contest as you could pick up so much 
neat stuff and low-down info from that. Also showed you a lot of the underlying
behaviour in the C language and how compilers would 'fill in the blanks'
in several cases.

As students during my college time we regularly got into friendly 
competitions to do the 'shoterst source xyz' or 'fastest' or even some
obscure 'smallest resulting ASM from the compiler'. Fun times..

Longest running one I remember was cramming a fully compiling and running
Conway's 'life' into as little C-source bytes as possible (excluding the 
playing field data, but it did have to read that..). I vaguely remember it 
getting down to a ridiculous 30-something bytes or so.

Again.. Thanks for the link. Definite reading material for a quiet moment..

							Bye, Arno.

It's one of the reasons I enjoy vintage software.  You might think old
programs are arcane and difficult.  Not so!  They are actually much
easier to understand than the monstrosities we have today.
