Hello👋🏻 I'm a software engineer who loves building #frontend tools. I'm also a hobby filmmaker currently making #StarTrek fan films. I never got the hang of making the bird site actually fun and useful but hope to give this one a try, so please come say hi. What's the coolest thing you've found here?
That's me and some of my awesome teammates!

Testing components that depend on things like localStorage or authentication can be tricky. Storybook makes it easy with our new module mocking API built on top of @vitest.dev's excellent mocking tools.

If you write Superman as if his defining feature is his strength he gets boring quickly, but his defining feature is how deeply he believes that the responsibility of the strongest is also to be the kindest, and to care the most - that's where the good stuff is.

Or at the very least, glitter-bomb them.
These are not police.
By law, they have to identify. If they won’t—copy their plates, call the actual police and let them know you are witnessing armed police impersonators.
