This week, I have been slowly exposing Audrey (age 7) to computer programming. This morning, I showed her a short shell script that blinks the LED’s on our router.

while true ; do
   led white on
   sleep 2
   led white off
   sleep 1

I explained to her how the loop works: LED on, sleep, LED off, sleep, repeat forever. Then I pointed out that I had started it blinking last night, but that it was not blinking this morning.

She told me “you might have a bug”.

I am so proud of her.
