building apps, testing AI, and turning digital ideas into income while traveling the world

30 minutes to build. $3,000+ to sell.

This guy uses Superapp AI to create iOS apps for restaurants, then charges $3K+ each.

Every restaurant needs one. Almost none realize how fast it can be built.

The opportunity isn’t the app. It’s selling it before everyone catches on.

ANCIENT LIGHTS

London has an interesting rule called “Ancient Lights.” If a window has received natural light from the same direction for more than 20 years, nearby construction that would block that light can be restricted.

@cleosoleil oops i did it again...

ELON MUSK'S GREAT-GRANDMOTHER?

A woman charging an electric car in 1912, over a century before today's EV boom

Early EVs were quiet, clean and popular with women because they avoided the dangerous hand crank needed to start gas cars

The future arrived early. We just forgot it.

@cleosoleil It’s a sad situation, but at least you’re free from a company that had turned into a dinosaur.

THIS IS THE MOST EVIL PUZZLE EVER MADE.

The box promises a peaceful frozen lake. The finished 500-piece image secretly adds a dog taking a dump.

Someone put it in a doctor's waiting room.

The person responsible deserves both a raise and a restraining order.

@cleosoleil I’m about to devour the whole thing.

@julianarvenholt Cute little bits of chaos.

[Teo @TeoSens]

@cleosoleil i'm waiting...

@julianarvenholt AI companies trained their models on pretty much every book out there, and no one said a word.

WHY IS ANYONE STILL TRADING MANUALLY?

- Be an 18-year-old student in China
- Build a trading bot with Claude Code
- Scan 60+ markets
- Sync everything against BTC data
- Find pricing errors
- First night: +$8,400
- Starting capital: $68
- Total profit: $218,000

@julianarvenholt It might burn through some tokens if it’s really going to analyze it “like an enemy.”

VIBE CODING'S BIGGEST BLIND SPOT JUST GOT A 30-SECOND FIX.

Every solo founder knows the quiet fear: you ship fast, leave one nasty security hole behind, and keep building while hoping nobody finds it.

Claude Security now lives in your terminal. It scans changes before a commit or red-teams the entire repo through the Claude session you're already running.

No extra API. No extra tokens. No separate tool.

Three modes:
Medium checks if you're ready to ship.
High goes deeper.
Max tries to break your code like a real attacker.
"Security later" used to be the tax on moving fast. Now it can be a pre-commit habit.

If you vibe code, install the beta before your next ship.

[Claude @claudeai]

The Claude Security plugin for Claude Code is now available in beta.

Scan your changes for vulnerabilities before you commit, or run a full scan across your codebase, all from your terminal on the Claude inference you already run.
