.NET Annotated Monthly | September 2020
This month in computing history: The first instance of a computer bug was found in September 1947. It’s called a bug because when this happened, it was a moth that wandered into the machine and caused the glitch. This is possibly now the world’s most famous insect. Check out the log report in the link with the moth taped to the paper. It was called a log report because they didn’t have bug reports yet. And it was on paper – they were made from actual logs at that time.

File that under "Things only programmers say".
I think that typing in and of itself doesn’t necessarily help you program. However, if you can type well enough so that you can focus on the problem solving and thinking that software development requires, that frees up some mental energy that would have gone to the keyboard. It makes it easier if your fingers can go as fast as you can think, but it’s not about the fingers themselves. Readers, what do you think?
