I like this setting for VS Code from Ben Frain. JUST show the vertical line for the current indentation, not all of them
```
"workbench.colorCustomizations": {
"editorIndentGuide.background1": "#00000001",
"editorIndentGuide.activeBackground1": "#ff9900"
}
```

TIL Oban's unique job period uses fixed time windows, not sliding windows.
A job with unique: [period: {7, :days}] can still allow duplicates 2 days apart if they fall into different buckets.
If you need sliding windows, use a custom query.

Oban unique job periods are not what you think - Fredrik Teschke
Fixed windows vs sliding windows: a subtle but important difference.

Got a few PRs in flight for Credo which cumulatively dropped the runtime from ~33 seconds down to ~9 on our 3500 file #ElixirLang codebase at work. 😁

Yeah it's here: hex.pm/packages/typ...
I've used it pretty extensively so far and it works great for my use case but there might still be some rough edges or missing functionality. I need to push a new release that will update Typst itself to 0.14

Speaking publicly about Elixir stuff (conference talks + podcasts) has gotten me every job I've had since 2020. (And that first one was a 50% pay bump.)
I interview pretty poorly, but having been seen being smart in public got me the foot in the door I needed to prove I could do the work.

Devs who write about their work/company; talk at conferences - lots of companies in the past used to not care much about this and not value it the least.
Feels like the tide is changing: people who do this but are not valued get hunted down by companies who understand this value

BRB, gotta go write a migration for the work DB.
i had a databases class in college in which we were designing a users table and the professor guided us to use (firstname, lastname) as the primary key, and i asked what we'd do if there were two people with the same name, and they said to include the social security number, i think of this a lot

How ProcessTree Saved My Async Tests
This post is about the trap I hit while mocking API calls in Elixir tests, why it happened, and how ProcessTree solved it beautifully.
