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)
