blackboard

2' on the blackboard. Why did you do that?"

When I was a kid, I had trouble seeing my teacher's blackboard. I just kept moving closer to the blackboard.

At this point, go to the next blackboard. Write after me: You can not debug Elm. There is no debugger.

Or, rather, feet in shoes in front of the blackboard. If you have 4 teachers for 100 students in 3rd grade, firing one and increasing the average class size to 33 students isn't a tenable option.

In one session at the blackboard, John introduced Lisp—all you could do with car, cdr, cons, cond, lambda, and recursion. Recursion had no place in mainstream programming at the time, nor did lambda calculus.

Engineers, especially, quickly learn that prospects aren't going to give them a blackboard and 2 hours to prove that the laws of physics insist they must buy.

Similarly I have dead-key layers for superscripts, subscripts, math, blackboard bold, Hebrew letters, keyboard symbols, and so on. Layers can also be chained, so, for instance, I have a fraction chain such that F 3 4 yields .

The algorithms prof was a shy lanky dude who went straight to the blackboard and wrote "computers are to computing what telescopes are to astronomy". at that point none of us knew who dijkstra was, so we just looked at each other like "huh?"

On the first day of the first course as a CS major, the prof said something like "in this course you'll learn how computers work from the bottom up", turned to the blackboard, and wrote Maxwell's equations. We laughed, and he said, "You're laughing because I got it wrong, no?

He then shone a laser at the ruler, so that the light bounced off and hit the blackboard. The lines on the ruler acted as a diffraction grating and a diffraction pattern was visible on the blackboard. He marked the peaks with chalk, then went back to the ruler and used the ruler to measure the distance from where it had been to the blackboard.

During undergrad I discovered the university's blackboard-like site sent plaintext passwords over http, and the majority of its use was over wireless. I went to the IT office responsible for the site, told them about it, and refused to give my name when they asked.

Good to see that someone left a message on the blackboard, making explicit how he liked the school. Also, interesting to see that some stuff held well against the tsunami, the damaged graduation hall for example still has everything in place except where the floor collapsed, and still looking good.
