Yesterday we had an excellent guest lecture, despite the fact that the LCD projector failed and so did the video camera. I’d even tested the camera beforehand, though we couldn’t get into the room to test the projector. But to no avail.

To compose my introduction, I tried to find my review of the speaker’s book, and it had vanished off the website where once it was. Only the Internet Archive saved me.

That’s two-and-a-half failures out of three, technology. When we welcome our new robot overlords, we’re going to find out they’re just as incompetent as the human ones.

Tangential further notes:

This seems an appropriate place to note that once a term my laptop, which I use for Keynote presentations, mysteriously fails to perform despite my having checked beforehand, every day, to make sure the presentation runs. So I give the lecture the old-fashioned way. (Students, interestingly, almost never complain about this, even on anonymous evaluation forms.)

It also seems an appropriate place to note that you can see that guest speaker, Ha-Joon Chang, of Cambridge, give a talk similar to the one I failed to record on YouTube.
