I think you’re overestimating the package in question. It’s about 50 significant lines of code total:

https://github.com/feross/safe-buffer/blob/master/index.js

It’s a tiny API wrapper in JavaScript for older Node versions. While useful for someone on older Node, it doesn’t really say anything about the author’s embedded system chops.

It’s looks like it’s just a polyfill. Not to diminish the achievement, but you’re correct: it’s doesn’t reflect on his embedded skills (if they even exist).

kudos for doing the quick research into the actual topic and background of the situation at hand instead of soap-boxing about hypotheticals.

This should have been mentioned in the original post as it gives some much-needed perspective about the scale of the contribution.

Good point, I definitely didn't research his actual library.
