Their UX and UI are their bread and butter, but as someone who has done extensive web app development for use on Safari browsers, if I had a nickel for every time their browser just IGNORED a standard, broke one that previously worked, or added new “features” that broke a standard, passing the responsibility of building a workaround down to individual developers… I’d have a few dollars anyway. I don’t have much faith their code is all that good compared to average under the hood and the UI, and I think their reputation unjustly leads users to turn a blind eye or give them a pass when their stuff DOESN’T work or works BADLY. “They’re Apple… everyone else seems happy. I must be doing something wrong.”
No, the OSI model is fine.
I’m talking more about sandboxing an interpreted app that runs a container that runs another sandboxed interpreted app, both running their own instances of their interpreter with their own dependencies and accessible through a web interface that is accessible through yet another container running a web server that is running in Python with a virtual environment despite being the only Python app on the container, which is then connected to from another sandboxed tab on a sandboxed browser on your machine.
But hey, at least it isn’t, god forbid, a MONOLITH. That would require someone to take the time to understand how the application works.
