He also made circuitjs, a very useful circuit simulator which I regularly use for prototyping. It lets you modify and probe elements in real time unlike spice simulators, so it is faster to modify a design in it.

I use spice simulators to check the final design since sometimes circuitjs can have instability issues in complex circuits involving stuff like the nonideal op amp.

He also wrote zsh ( https://en.wikipedia.org/wiki/Z_shell ) as a sophomore in 1990, moved onto other things a few years later, and a couple decades later in 2019 it became the MacOS's default shell.

I remeber using this when it was Java applet. Now he has converted everything to JavaScript for everyone to use. What a legend!

Reminds me of this [1] I made back in 2005 in Flash action script, thankfully bought back to life by Ruffle [2].

You can fix the ends of the string by pressing space. When both ends are fixed, you can you can drag the beads and release them.

No big deal, but hey I was quite happy with myself back then..

Thanks!

Never heard until now. Looks interesting. Thanks for sharing, but is it available now?

I have fond memories of fiddling with the wave simulations on this website during high school!
