The code examples and direct quotes are all from Raymond's talk. I've reproduced them here for my own edification and the hopes that others will find them as handy as I have!

Because this code take so long to run as-coded below, I recommended to follow it
up with a check for file duplicates (fdupes -dN in linux seems to work)

After downloading, you can combine them into a single corpus file by concatenating:
find . -name "*.txt" -exec cat '{}' ';' > dirty.txt

Then you can use whatever means you wish to clean up the text and remove unicode symbols
and so on
