The portable programming lecture went pretty fine, compared to what I feared. Yes, I did lose my thread of thought several times, and got mixed up with my tongue (saying "backslash backslash" in front of other people while being recorded on video is a nightmare).
About 20 people came, most of which I knew. No masses of people from Tel- Aviv whom I have never seen, and on the other hand- not a lecture for 5 people with no interest whatsoever. Rather surprising, since I did not think people cared about portability at all. After all, most people do not have many machines to run on.
OK, I crossed the line, now I start thinking about the next lecture.
Maud, my cat, had an operation today. She is the poorest cat I have ever seen, dragging herself around, wearing an Elizabeth collar. She has a piece of plastic sticking out of her shaved skin, to allow for the fluid to pour from her. She has not eatten for a week, and she has lost about 1 Kg of her weight.
