for me, I think we've reached AGI when claude started disabling rubocop tests instead of fixing the code

it's a simple Newtonian n-body sim. You can drag emojis into orbit around the Sun, switch to an Earth/Moon view to see lunar orbit up close, or throw things into a black hole
what's the most ridiculous "stable" orbit you can get?

I was explaining orbital dynamics to someone today (at a very basic level) and realized it would be way easier to just show it.
so we built this little gravity sandbox in about 30 minutes with Claude (link below) 👀
it's really fun to try and get a stable orbit 😊

working on improving the user experience of the @MuteDeck Stream Deck plugin with:
- Show the supported apps with each action
- Add a ton of pre populated actions to save manual work
- Custom -> Other actions for simplicity
the action is powerful, but labeled too complex

there are a lot of PNG -> SVG converter tools, but they all suck
Adobe, canva, freeconvert, and more have issues with anything that is a little more complex then an icon. Note the squiggly lines 👇
convertio . co was spot on - if you need an SVG conversion, go there 😊

it might seem obvious, it might not, but make sure your checkout flow is seamless
need the user to login first? remember what they were doing and automatically continue it, once they're logged in
new account? same deal, continue automatically after they've registered

enabling error logging on an existing frontend is going to hurt at first
you'll spend some time filtering out extension issues, anything that's unrelated to your codebase
but the end result of having no errors on your frontend is worth it
