kept catching myself mouth breathing while working at my desk.

problem is, you don’t notice it when it’s happening.

So I made a tiny free web app that beeps when your mouth opens.

No facial data collection. No ads. Just a simple awareness tool.

I spent $6k USD on the alex hormozi course to learn about marketing. This is the most money I've ever spent. Always thought it would be important to invest in yourself. Still wanna throw up.

Tried recursive React components with Server Components + Suspense fully expecting the universe to implode. It just… worked.

@mcrovero @EffectTS_ @nextjs does this cause the page component to become an anonymous function causing error logs to be harder to debug?

I always forget how to setup ssh keys for git deployments. Here's a quick cheat sheet.
ssh-keygen -t ed25519 -C "[email protected]"
eval "$(ssh-agent -s)"
ssh-add ~/.ssh/id_ed25519
cat ~/.ssh/id_ed25519.pub
-- paste into github settings --
git clone [email protected]:USER/foo.git

“your scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.”

Engineers often fall into this trap. Spending too much time on features that take too long to implement. Cut 20% of the features that take 80% of the time.
