We had an optics lab at the Faculty of Engineering, Lund University about the idea behind the FlatFrog display system back in 2014 (I think) and I remember thinking it was genius.
It bothers me immensely that they redirect docs for services that work perfectly fine by themselves to amplify docs with a note that says something like "use amplify".
Other than that, using AWS services directly is always a much better experience. In my opinion amplify is like a dumbed down version of that.
One of the best tips I have gotten from the internet is to never copy and paste code you have not written yourself. Even rewriting it verbatim makes you think about what it is you are actually copying.
Ladislav Vagner, a legendary programming tutor at FIT CTU, is a known proponent of being extremely cautious when copying code, even your own. He gives programming proseminars where students guide him as he codes the solution to some problem, e.g. mathjax-like typesetting in C++. It is a common theme in the proseminars that a bug is introduced by copying code. Probably on purpose, like many of the other bugs that students are supposed to point out.
I think that’s true if you’re trying to learn a new tool or technology. You probably won’t learn as much following the Rails or Django tutorials if you’re just pasting all the code. But if you’re just looking for some esoteric workaround for some very specific tool and use case, I think it’s fine to paste. And the latter makes up the overwhelming majority of my Stack Overflow visits.
It's also good legal advice. It's now legally possible for you to copy and paste code directly from stack overflow because they made an effort to assert a compatible license over works published on their site. However, the same can't be said for most other code snippets flying around out there.
You could use GitHub issues for posts and comments, fetched using the GitHub API. I did a proof of concept of this a long time ago [0]. Not sure if it still works.
Pretty much the same with SVT in Sweden. They also have a site called ”öppet arkiv” (open archive) claiming to be one of the world’s largest TV archives.
Just because they are both open source does not mean they share a common goal or methodology. My guess is that KaTeX was written to overcome the deficiencies of mathjax.
