I still remember a 2 day assignment we had of finding scientific articles, and classifying them as trustworthy or not. Ie, was it in a peer reviewed journal vs a study at a "clinic" that has bias in the outcome. I remember that to this day and feel like it was a major shift toward my ability to think critically
I regularly bisect commits in the range of 200k (on the low end) for finding causes of bugs. It takes me minutes. Pretty crazy
