the engineer who built Claude Code just dropped a 28-minute video on how to write prompts that actually work
I've seen $300 courses that don't cover what he shows in the first 10 minutes
CLAUDE.md files, memory shortcuts, parallel sessions, prompting patterns
all in one video and completely free
works whether you're a developer, a beginner, or someone who's been using Claude for months
based on this, I put together 18 things you can copy and use in Claude today
full guide in the article below
A Chinese engineering student spent $4,000 on two Mac Studios and a Mac Mini. Put them on his desk. Labeled each one with a sticky note: UI/UX. DEV. ADMIN. Connected two monitors. Satellite maps on both screens.
His parents thought he was building a startup. His professors thought it was a thesis project. His roommate thought it was overkill for homework. He let all of them keep thinking that.
Then someone noticed what the three boxes were actually connected to.
A wallet. Making $104K. Betting on the temperature.

Two Mac Studios and a Mac Mini doing one thing. Claude pulls live pilot weather data. METAR. TAF. Real sensors from real stations. Updated every 1-3 hours worldwide. Temperature accurate to a tenth of a degree. The DEV box compares it to prediction market prices. When they don't match the UI/UX screen flashes. The ADMIN box logs the trade.
Flash. Trade. Green.
$25 on Tokyo hitting 16C on March 20. Payout: $12,452. $24 on Chicago reaching 54F on March 11. Payout: $12,398.
Eleven dollar bets returning five thousand. On the temperature in a city most people can't find on a map.
A friend who flies commercial told him pilots get atmospheric data hours before any public forecast. This data is free. Aviation safety requires it. Nobody outside of aviation even looks at it.
He looked. Pointed Claude at the feeds. Said: find me every city where the real temperature doesn't match the price.
Claude found dozens. Every single day. Tokyo. Chicago. Wellington. Atlanta. Ankara. Lucknow. Cities on six continents. All with weather stations publishing data that nobody in the markets is reading.
The three boxes run 24/7. Even when he's in class. Even when he's asleep. The satellite maps keep updating. The DEV box keeps comparing. The screen keeps flashing.
His roommate finally asked what the setup actually does. The student showed him the balance. The roommate didn't say anything. Just asked for a third monitor.
34K people watching. $94K still loaded in active positions. Two Mac Studios. One Mac Mini. Two screens. One quiet kid who realized the most predictable thing on Earth is the thing everyone ignores.
The weather.
@sizzle_sarah@USABookClub Yes it had to happen canโt lay on your back nd expect for anything to get omelette takes eggs nd guess what you got to crack um
