In 1972 Warren Buffett paid $25 million for a candy company that earned $4 million a year. by the time he stood in that Florida classroom it was throwing off $60 million, on the same recipes, with almost no extra capital.
he explained the whole thing for free, in plain English, to a room of MBA students.
no consultants. no market research. their idea of due diligence was buying a box and eating it.
See's was selling 16 million pounds at $1.95. Charlie and Buffett only had to decide one thing: whether that box could quietly sell for $2.25 instead. by 1998 it was 30 million pounds at $2 a pound, and $55 million of the $60 million came in the three weeks before Christmas.
he raises the price every year on December 26th. the day after the rush.
and the edge is not the factory. it is that every Californian has a warm memory attached to the box, which means the girl behind the counter is the asset.
"If the salesperson smiles at that last customer our moat is widened. if she snarls at them our moat is narrowed."
you cannot see a moat move day by day. ten years later you can see nothing else.
HOLY SH*T, ONE PROMPT TURNS CLAUDE CODE INTO A FULL REVERSE-ENGINEERING LAB WITH REA
paste it once and your agent will:
- open Windows .exe files, Android APKs and iPhone .ipa builds
- follow any button on screen down to the function that runs it
- turn one network capture into a map of the app's API
- unpack firmware and trace it into native code
- log every claim in an evidence ledger, so nothing is a guess
130+ tools in one free MCP, one command to install: npx rea-agents setup
only aim it at software you own or are allowed to analyze
send it to Claude Code, then read the article below before your first run ↓
this is pure f*cking gold - Claude + Obsidian is my most-used setup, and here's how to get it in 3 steps
> Claude reads and writes directly into your vault - searches notes, creates files, drops content under specific headings, summarizes meetings into new notes
> if you run Obsidian as your second brain, this turns Claude into the thinking layer sitting on top of it
the setup, 3 steps:
1. install the "Local REST API" plugin in Obsidian, enable it, copy the API key
2. open your Claude Desktop config:
- Mac: ~/Library/Application Support/Claude/claude_desktop_config.json
- Windows: %APPDATA%/Claude/claude_desktop_config.json
3. paste this in:
{
"mcpServers": {
"mcp-obsidian": {
"command": "uvx",
"args": ["mcp-obsidian"],
"env": {
"OBSIDIAN_API_KEY": "your_key_here",
"OBSIDIAN_HOST": "127.0.0.1",
"OBSIDIAN_PORT": "27124"
}
}
}
}
> restart Claude. done
now you can say "summarize my last meeting note and save it as a new file" and it just does it 👇
