Things I actually lived
Written from my own narration. Dated, first person, nothing invented.
What 33 closed pull requests actually taught me
I stopped picking open-source projects by how famous they were
27 of my 30 merged pull requests were the same kind of change
I checked whether my own changelog credits were real
A four-line fix got credited and a hundred-line one did not
Integers larger than 64 bits, quietly losing precision
Three crashes in three projects, all the same shape
The booking system that sold the same slot twice
Six account types, real money, and the security pass before launch
The model found the fraud ring. That was the easy half
Easy, medium and hard are hiding the thing you want to know
