Mine disappeared some time ago. Someone borrowed it and didn't tell me.
But I have been able to reconstruct some of the graphs from appendixes in
other articles, and I found some of the tabulated data on the web. I'm
still missing the Gaussian stuff, but I got most of the rest.

I've heard lots of good stuff on Pease's book - what do you think of it?

Just for fun, I did a search on "Widlar". The search uses Boyer-Moore in
optimized assembly and does a little over 100,000 files per second.
That's 10uS per file.

Here's the results. It found five references in 167,000 files in 1.6
seconds:

This is on a 200MHz Pentium with a 5400 rpm drive. I would expect a bit
better performance with a 2GHz machine like the rest of you are running:)

It may be difficult just telling them to write better code. If you have
to tell them, they have no clue what you are talking about.

What you need to do is encourage them to waste as much ram as possible.

Then when the s**t hits the fan, you can be the high-priced hero that
bails them out of a tough spot:)
