Eli Folio is the portfolio of Erfan Hardanian.
I learn from history and borrow the best ideas. I find problems and build what fixes them.
What I’ve built
-

10,407
US-listed companies it starts from.
-
Writing the rules that decide which programs may run took hours for every app.
Kavikah-vee
Writes the application control rules that tell Windows which programs may run. Anything not on the list is blocked.

-
On an old file server, one stolen password often opens every project folder.
Kelikeh-lee
Sets who can open each folder on a shared drive. It changes nothing until a person types how many folders will change.
Undo
Every change can be undone, and it runs on real file servers today.
-
Hundreds of books and podcast episodes, and nowhere to search them.
Yadiyah-dee
My notes on how great thinkers and doers made decisions, and the mental models behind them, from Alexander the Great to Warren Buffett. My other tools and assistants search them as they work.
