= Bisection
{disambiguate=software engineering}
One of the Holiest age old debugging techniques!
<Git> has some helpers to help you achieve bisection Nirvana: https://stackoverflow.com/questions/4713088/how-to-use-git-bisect/22592593\#22592593
Obviously not restricted to software engineering alone, and used in all areas of engineering, e.g. <video Air-tight vs. Vacuum-tight by AlphaPhoenix (2020)> uses it in <vacuum engineering>.
The cool thing about bisection is that it is a brainless process: unlike when using a <debugger>, you don't have to understand anything about the system, and it incredibly narrows down the problem cause for you. Not having to think is great!
