jimkang / unzip-bandcamp.sh
Created February 19, 2021 03:03
When you download from Bandcamp, the zip file comes with no directory structure, so this gives it one. Explanation: https://jimkang.com/weblog/articles/bandcamp-unzip/
#!/bin/bash
for file in *.zip
do
filename="${file%.*}"
# Filenames can't contain /. So, I wonder
# what Bandcamp would do if they had AC/DC?
unzippath=$(echo "$filename" |sed -e 's/ - /\//')
mkdir -p "$unzippath"
unzip "$filename" -d "$unzippath"

jimkang / get-entries-in-date-range.sh
Last active April 5, 2020 19:26
Simple script for getting markdown files in a certain date range (assuming the files use a common Zettelkasten naming convention in which every file starts with YYYY-MM-DD).
#!/bin/bash
src=.
start=$1
end=$2
if [[ ! $start ]] && [[ ! $end ]]; then
printf "Usage: ./tools/get-entries-in-date-range.sh [start string] [end string]\nEnd string is optional.\n\nExample: To get filenames that come after 2020-03 (anywhere in March) but before 2020-03-29 (assuming files follow this naming convention):\n./tools/get-entries-in-date-range.sh 2020-03 2020-03-29\n";
exit 1;

out_file.write(json.dumps(data))

Get static cubic easing values. I just ran these in the Node REPL to get the numbers.
var { easeCubic } = require('d3-ease')
var { range } = require('d3-array')
range(0, 1, 0.05).map(easeCubic).map(n => n.toFixed(2)).join(';')
