"""
Download all ClassDojo photos and videos in your timeline.
by kecebongsoft

How it works:

1. Fetch list of items in the timeline, if there are multiple pages, it will fetch for all pages.
2. Collect list of URLs for the attachment for each item
3. Download the files into local temporary directory, and also save the timeline activity as a json file.

dsample

/* run this in the console on the ClassDojo page */

function download(url) {
  fetch(url).then(function (t) {
    return t.blob().then((b) => {
      var a = document.createElement("a");
      a.href = URL.createObjectURL(b);
      var n = url.lastIndexOf("/");
      var filename = url.substring(n + 1);
      a.setAttribute("download", filename);

Typey Type custom lessons

Typey Type is a practise site for stenotype typists. If you don't know what stenotype, or Plover is, it's the method used for closed/open captioning (subtitles) and realtime courtroom transcriptions. Where you may be used to a 'qwerty' layout keyboard with anywhere from 60-110 keys, a stenotype machine has 25-36 keys, and they're played in chords, like a musical keyboard, with each depression of a chord of keys signifying a word (or partial word).

To put some of this together, I've used Plover dictionary lookup tool.

From what I've seen, most people take months or years to learn stenotype. I'm (initially) trying to pick it up in a month, with only a short amount of practise at the beginning of each day. Because of this, I'm going to be trying to think about how to speed up the learning process, and a lot of the beginning lessons here are going to be

Standardised healthcheck API

This is a draft proposal for OpenAPI, or an extension thereof, which details an approach for microservices to communicate health in a detailed manour.

The depth parameter is intended so that the complete architecture underpinning a service can be discovered.

The bearer header allows services to control access to detailed health information. This also means that integration across boundaries can be controlled using different authoritive identity providers.
