You can have a lot of fun with a tiny traffic light using an Arduino and three different color lights. There are bunch of things you can do to build on it.

- 3d print a stand (here's one I did https://github.com/SalvatoreT/howmm/blob/master/week06/Traff...)

- incorporate an infrared sensor + infrared light to simulate triggering the red -> green flow

- make an intersection with each of the lights working together to show the right thing at the right time

- add a crosswalk

A while back I wrote this useless site where you put in a string and it gives you a Ruby one liner to output that string.

https://monkeynumber.xyz/

i.e. "bird" gives you

ruby -e "srand(267343);puts 4.times.map{rand(97..123).chr}.join"

which will return "bird" if you run it from your command line

I do a brute force attempt at it, but (maybe one day) will peel back Mersenne Twister and get a more optimized implementation.

I wonder if growing up with similar-aged siblings gives you a natural advantage at this game.

I could imagine developers using something like this to get credentials off laptops.

If a lot of ChatGPT users were students, I would expect a drop during summer vacation.

I predict another article from the Washington Post in August/September about how ChatGPT is seeing a rebound in usage.
