Just FYI, often if you hit a bad link from my old archive.org account, like this:

http://ftp.archive.org/movies/lisarein/radio/kqed/crowdestimation.html

just replace "http://ftp.archive.org/movies/lisarein" with:

http://www.lisarein.com/videos/

So this:

http://ftp.archive.org/movies/lisarein/radio/kqed/crowdestimation.html

would become this:

http://www.lisarein.com/videos/radio/kqed/crowdestimation.html

but please do email me and let me know to fix the page itself
(as you always do)
