Extend URLSearchParams to object

There must be a reason this is a bad idea or it would be included in the API, right? 😅

URLSearchParams.prototype.toObject = function() {
  return […this.keys()]
    .reduce((o,k) => ({ …o, [k]: this.get(k) }), {});
}

Git Rollback Alias

Related to the Alias for Git sanity post from a few years back, recently added another to ~/.gitconfig

[alias]
  revert-merge = !git revert -m 1 $1
  rollback-merge = revert-merge

Where $1 is the commit hash. This only works for rollback of a merge commit on the main branch.

Southern Reach

Where lies the strangling fruit that came from the hand of the sinner I shall bring forth the seeds of the dead…

Deferred Promise

Found myself in a situation where I wanted to execute a process and then check back on it later to be sure it had completed.

class MyClass {
  constructor() {
    this.readyPromise = new Promise(
      resolve => (this.readyResolve = resolve)
    );
  }

  async executeProcesses() {
    await // ...executing processes...
    this.readyResolve();
  }

  ready() { return this.readyPromise }
}

Predator Prayers

People want to give up the responsibility of being able to understand. And because they can’t understand, then they have faith. And they put their faith into people who say they can understand. And I think that’s a situation that’s ripe for a predatory relationship.

Chrome extension with imports

To write a Chrome extension that allows ES6 imports, imitate <script type="module"> with a dynamic import:

Chrome extension MV2 access to page data

Chrome extensions exist in an “isolated world” to prevent global var collisions between the website and the extension that runs on a given website. This mostly applies to content_scripts in an extension.

E.g. window.foo: my extension declares foo in the global scope and the website the extension runs on also declares foo in the global scope. With “isolated world” scoping for the extension, this is not a worry since it doesn’t share scope with the web page it runs on.

Comparison Formulae

Collecting performance metrics, I needed a way to compare optimization before/after numbers into some meaningful value that would impress the brass.

Portal

Pika: Have you ever seen a portal?

Kirik: Yes.

Pika: Was it like a doorway or a window?

Kirik: It looks like the room you’re in but the room’s dimensions start changing around you.
