Is this me or the audio is completely out of sync?

"The Coding Train is live now" yeah right it was 4 hours ago thanks alot youtube for teasing me -.-

Dan, this is cool ! I couldn't wait for you to revisit this, as its something I've been thinking about & playing with(in various forms) for a LONG time, especially the "drawings" since those few rather recent youtube vids demo'd the ideas. I was pretty stuck there, & you really came through. You knocked it out of the park yet again. Grand Slam Dan thE Man ! imo the Fourier series/transforms etc. are one of thE most interesting, EXTREMELY useful(throughout engineering/technology etc.) & Beautiful math objects/concepts there is, right up there with & perhaps above mandelbrot/fractals & such. BIG THANKS !

This isn't the first time you multiplied complex numbers. that was in your Mandelbrot video, which helped me get my head around the subject. Thanks for that.

The only thing i would watch for 3 hours on my phone. And please, dont worry about your fourier obsession, the more fourier videos, the better

Can you start doing programming tutorials on quantum programs

why did i not get the notification for this live stream from youtube ?

Don’t know if you solved the saving bug. But I think you were calling a global save function. Probably the save function of p5js? That’s why you’re function wasn’t called and something else got saved. Probably just saving the object as an json dump. Bug still seems to be in ml5. And I think that the href in save of ml5 is getting to big with the base64 encoding. There is probably a limit to the length of an href. So the save trick in ml5 needs to be different. Need to watch the last minutes of the stream, so maybe you’ve find the solution on the end ;-)

What is the name of that song you used in the beginning of the stream
