My absolute favorite part about McMaster-Carr as a 3d printing enthusiast is the 3d models. Countless side projects have been saved with the ability to print a weirdly specific m<x> nut/bolt to validate a build before purchasing them in bulk.
Simple website for extracting CRX and XPI files (browser extensions). Useful for learning how browser extensions are built, and more so to share with your product team so they are easily able install development versions of your extensions.
For firefox xpi files its that simple, for chrome crx files, you have to strip the crx header from the file before it can be opened as a traditional zip file (so read the header to find its length then strip it). But yeah it's fairly simple. This was mostly created as a simple tool for the product team at my old company to extract crx files so they could side load development builds without them having to install anything or be aware of the fact that these are essentially just signed zip files (much like Apples xip format).
