Did you know you can run ngrok (without installing it) by using tunnel.us.ngrok.com as a reverse tunnel? Try this: ssh -R 80:localhost:80 http It's the equivalent of `ngrok http 80`

This paper shows that you can predict actual purchase intent (90% accuracy) by asking an LLM to impersonate a customer with a demographic profile, giving it a product & having it give its impressions, which another AI rates. No fine-tuning or training & beats classic ML methods.

Server load so high you can’t even SSH in? 👉 Use this command; ssh -o ConnectTimeout=1 -o ConnectionAttempts=1 user@host "nice -n -20 bash" It gets you a high-priority shell when nothing else works.

💡 DB Design Pro-tip: Soft Deletes Soft deletes: instead of removing a row, you mark it as deleted (e.g. deleted_at TIMESTAMP). Great for undo, audit trails & not breaking FKs. But! If you query the base table directly, half your code will forget to exclude “deleted” rows.…

Tip: You don't need python-dotenv, use "uv run" with --env-file, and your env vars from .env get loaded. For example, if you've got a @FastAPI project you can run it locally with env vars like: uv run --env-file .env fastapi dev
