I tend to be something of a digital packrat. If there’s interesting data somewhere, I’ll collect it just in case I want to do something with it.
Helpful? Usually not. But it does lead to some interesting scripts.
In this case, I have a site that hosts videos. I want to download those videos and get a text based transcription of them. With new AI tools, that shouldn’t be hard at all. Let’s give it a try!
Spend a month making one beautiful thing per day, given a bunch of prompts. A month late, but as they say, ’the second best time is now'.
Let’s do it!

NOTE: This currently doesn’t work in Safari. Something funny with the p5.sound addon. I’m working on it.
Part 1: Create a virtual machine with the following instruction set:
snd Xplays a sound with a frequency equal to the value ofXset X Ysets registerXtoYadd X Yset registerXtoX + Ymul X Ysets registerXtoX * Ymod X Ysets registerXtoX mod Yrcv Xrecovers the frequency of the last sound played, ifXis not zerojgz X Yjumps with an offset of the value ofY, iffXis greater than zero
In most cases,
XandYcan be either an integer value or a register.
What is the value recovered by
rcvthe first timeXis non-zero?
I’ve recently started to listen to audiobooks again (The Aeronaut’s Windlass). If you buy books through Audible or some other setup that has their own app, it’s a straight forward enough process. On the other hand, if you have them on CD and want to play them on a mobile device… It’s a little more interesting.
I tried a few different apps that purport to do exactly what I wanted: import an audiobook as a folder full of MP3s and play them, but none that quite meet what I wanted. Since I also listen to a lot of podcasts and have more than one podcast app that I really like (I’ve used and liked both Downcast and Pocket Casts), I decided to see if I couldn’t use one of those as an audiobook player.
Last week we parsed some music. That post was in a bit of a hurry, so we had to leave off a fair few important pieces (like ties and slurs for one; chords for a rather bigger one). We’ll get to them soon, but for now we want to actually get something playing back.
It’s been a bit, but as you may have noticed life is a bit mad at the moment. But I’ve still made some progress.
When we left off last time, we’d finished the first step towards making some lovely music with Racket: tokenization. Now we want to take those songs and form them into something actually approaching music.
It’s been a bit since I’ve had time to post1, but I’ve got an interesting new project that I’ve been working on. It’s a bit more complicated, ergo spread out over a few posts, but those tend to be the more interesting posts anyway, eh?
The basic idea is that I want to be able to write and play music in Racket. One end goal would be to make a library available for the C211 class to give them something else to work with (in addition to <a href="//blog.jverkamp.com"/wombat-ide/c211-image-api/">images and <a href="//blog.jverkamp.com"/wombat-ide/c211-turtle-api/">turtles). To that end, here’s my current plan of attack2:
Sounds like fun! Let’s get started.
