Automating onboarding is not worth it.
I’ve spent years trying to keep READMEs, .env.example, Makefiles, setup\.sh scripts, CodeTour, architecture docs and other things updated.
Nothing beats a 1h-call with a senior developer on the team.

Can we just archive `create-react-app` already?
It's not recommended in the official docs anymore, hasn't received updates in over 3 years, and doesn't work with React 19.
It's basically just leading new developers into a dead end.

I'm looking to call a GraphQL API while making sure type safety and IntelliSense are supported.
So far, I have:
- 8 new dependencies added
- 2 new config files
- 3 new commands in package.json
- 2 CI workflows updated
- tsconfig.json changed
- .vscode/settings.json changed

Writing an article:
“I must explain the fundamentals well. 1200 words for an introduction is not enough. You can’t possibly build a todo app without understanding how semiconductors work”
Reading an article:
*scrolls past every text*
*checks code snippets*
“hmmm”

Cool trick I found in `create-t3-app`: create a middleware to slow down requests on purpose in development.
Great for identifying waterfalls, building pending UI, and it doesn't make the *entire* app slow like when throttle it on DevTools.
This one is for tRPC, but can easily be applied anywhere.

Migrated my dot com from using `npx serve` to a simple Caddy server.
Such a simple switch, the Caddyfile is 6 lines. Memory usage went down by 9x.

just finished migrating a suite of 500+ tests from Jest to Vitest:
- a lot of copy and pasting to remove globals
- esm/commonjs issues were the biggest pain
- didn't need to update a single test, just setup files
- existing jest matchers just worked

One of the most important skills in Software Engineering is being able to identify essential complexity and eliminate unnecessary complexity. Minimize creating complexity at all where possible.

thoughts after playing w/ nextjs app dir for a week:
- the simplicity of fetching data in server components is awesome
- layout.js, loading.js etc is a great mental model, I missed that in pages
- beta docs are pretty good, didn't need any tutorials
- overall DX is better than pages
