I started to write a new editor not too long ago and had it about half done after two days.

You can't prove anything about a program written in C or FØRTRAN. It's really just Peek and Poke with some syntactic sugar.

A bomb is blown up only once—but one bot can become many, and quickly get out of control.

I think editors have to come out of a certain kind of community.

I got tired of people complaining that it was too hard to use UNIX because the editor was too complicated.

If you stay up late and you have another hour of work to do, you can just stay up another hour later without running into a wall and having to stop. Whereas it might take three or four hours if you start over, you might finish if you just work that extra hour. If you're a morning person, the day always intrudes a fixed amount of time in the future. So it's much less efficient. Which is why I think computer people tend to be night people - because a machine doesn't get sleepy.

Take responsibility for the things you build and invent.
