I received an email this morning from Cecilia d'Oliveira - Executive Director of MIT OpenCourseWare asking for a donation to help support this program.
I'm sure that many HN readers are familiar with OCW and may have received the same message, but just in case you haven't, I'd like to encourage you to take a look at their site and follow up with a donation if you can.
