How to Squash and Rebase a Git Branch

We gotta Git out of this place.

It can be tiresome to rebase feature branches with many commits. You may have several commits that conflict with your main branch.

“Now where on this map is node_modules?”

Source maps are files that map your minified CSS or JavaScript back to the original code. They allow you to use your browser’s development tools to debug minified code as if it were the original. Also some error capture tools, such as Sentry, can use source maps to report errors for the original code.


A Problem with Duplicated Mutable Constants

Hey! You’re just like me!

Optimize your PNG’s with oxipng and pre-commit

Artist’s impression of a PNG optimizer.

PNG’s can be losslessly optimized to reduce their file size, by picking a better compression algorithm for the given image. The savings can be significant, like 50% (especially for macOS screenshots). This is an easy way to make web sites load faster.
