Git -Xours -Xtheirs arguments

Git provides a helpful argument to prefer one branch or the other to “clobber” merge conflicts:

git merge main -Xours
git merge main -Xtheirs

I always get confused what the “X” means. I always assume “X” means mark which branch to clobber. Like “X” out their branch. Or “X” out our branch. Please wipe this mnemonic from your brain!

“X” means “PREFER”

“PREFER” the changes in their branch or “PREFER” the changes in our branch.



Humans don’t know what they care about

If you hand over the management of your civilization to machines, you then lose the incentive to understand it yourself or to teach the next generation. […] Up until now, we put a lot of our civilization into books. But the books can’t run it for us. So we always have to teach the next generation. If you work out, it’s about a trillion person years of teaching and learning in an unbroken chain that goes back tens of thousands of generations. What happens if that chain breaks?

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...

  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.
