I was recently observing a couple programmers attempt to fix a bug and watched (with considerable tension) the painstaking stabs in the dark as they tweaked and changed different lines of code.
I instantly knew what I would do, and it is much more similar to a binary search (see example below) that rapidly solves almost every bug I come across.
This is an unofficial list of repeated sayings I have found in my studying of startups. This comes from reading, listening, watching, and working in a YC company.
Make something people want. [1, 2, 3] Talk to users. [4, 5] Do things that don’t scale. [6, 7] A small number of users that love your product is better than a lot of people that like your product.
