MP4 from frame sequence + audio file

See the resulting 2K video on Vimeo

Let's say you export a sequence of PNGs from canvas-sketch animation into a tmp/ folder. If you have an audio file, you can use the below FFMPEG command to mix the frames and audio into a high quality MP4 file that can be uploaded to Twitter, Vimeo, etc.

Beat-Sync Generative Art

Let's say your canvas-sketch program isn't an animation, but instead exports hundreds of variations on a generative algorithm. You want to mash them all together to create a video that feels somewhat in sync with the music.

I solved this problem, found a hint here: https://github.com/scaleway/initrd/tree/master/Linux 184.

Here is what I did:

Edit the “Tags” field in the server definition and add “INITRD_POST_SHELL=1” as one (or the only) tag.
Reboot the server
Wait until you get a shell

Clojure Destructuring Tutorial and Cheat Sheet

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.
