Somebody at MIT was nice enough to make available the videos for lectures on Structure and Interpretation of Computer Programs, by Abelson and Sussman.
It's a refresher in just how powerful Lisp is. For a language approaching 50 years old, it's pretty amazing.
I always crack up a little when I think about the reasons Lisp and Smalltalk couldn't go "mainstream" - why, they use too many...
I saw a note in the paper that Western Union has sent their last telegram, shutting down a 150-year-old business. Wish I'd known it was coming, I'd have sent "What hath God wrought?" to several people. (I know they just added "@" to Morse code a couple years ago... figured it would be around forever.)
The book The Victorian Internet provides an interesting and readable history of the telegraph.
