Downloading data

Data source: https://placedata.reddit.com/data/canvas-history/2023/index.html

But I have cleaned up it into Apache Arrow format for sanity. Download here and put it at the repo's root directory.

Btw, you can always copy code blocks including julia>, the Julia REPL is smart enough to ignore them when pasting.

After downloading, the folder structure should look like this:

> ls
main.jl  Manifest.toml  place_color_zstd.feather  Project.toml  README.md

Setting up Julia

Download Julia, juliaup is recommended (here).

Navigate (e.g. cd) to this repo's root directory. And run:

julia --project=.

julia>

For first time only, you need to instantiate the dependencies, hit ] once to enter pkg> mode:

(Bad_Apple_rPlace) pkg>

enter instantiate and hit enter:

(Bad_Apple_rPlace) pkg> instantiate

Afterwards you can hit backspace to return to REPL mode.

Running

You should now be able to run the following:

julia> include("./main.jl");

julia> main(; test_run=true)
Progress:  97%|███████████████████████████████████████████████████████████▎ |  ETA: 0:00:00
Done!

You should see a bad_apple.mp4, if you set test_run=false, it should take about 10 minutes to render the full movie.
