.gitignore Everything by Default

The article proposes reversing the typical .gitignore approach by ignoring everything by default and explicitly allowing only specific files to be tracked, rather than allowing everything and selectively ignoring unwanted files. This method prevents accidental commits of temporary files, IDE configs, and environment variables by requiring developers to actively whitelist files they want in the repository. While not suitable for every project, this alternative approach can be especially useful for repositories with many local files and dependencies.
