Himawari-8 animation tutorial

Here’s how to make animations like this one. It requires intermediate Unix command-line knowledge, to install some tools and to debug if they don’t work. You’ll need these utilities:

• curl (or you can translate to wget)
• convert and montage, part of ImageMagick
• ffmpeg, plus whatever codecs
• parallel, for iteration that’s nicer than shell for loops or xargs
• run everything in zsh for leading 0s in numerical ranges to work

Comparison of npm scripts vs Gulp

npm scripts

Pros

• npm scripts are low-level and leverage the actual library you want to use (example: "lint": "eslint ./")
• package.json is a central place to see what scripts are available (also npm run will list all scripts)
• When things get too complicated you can always defer to another file (example: "complex-script": "babel-node tools/complex-script.js")
• npm scripts are more powerful than one might first think (pre/post hooks, passing arguments, config variables, chaining, piping, etc...)

  return new Promise(resolve => {
    setTimeout(() => resolve('☕'), 2000); // it takes 2 seconds to make coffee

gif-from-tweet

There are so many great GIFs out there and I want to have copies of them. Twitter makes that harder than it should be by converting them to MP4 and not providing access to the source material. To make it easier, I made a bash pipeline that takes a tweet URL and a filename, extracts the MP4 from that tweet and uses ffmpeg to convert back to GIF.

Dependencies

• ffmpeg
