The principal quantum number thing fully determining energy is only true for the hydrogen emission spectrum for which we can solve the Schrödinger equation explicitly.

For other atoms with more than one electron, the orbital names are just a very good approximation/perturbation, as we don't have an explicit solution. And the internal electrons do change energy levels.

Note however that due to the more complex effect of the Lamb shift from QED, there is actually a very small 2p/2s shift even in hydrogen.

The best way to learn about them as of 2020 is to Google into Know Your Meme.

Non-technical skills were moved to: Ciro Santilli's skills.

This has not been updated since 2016 after Ciro got a job, because it is too hard to put a number on any skill.

What really matters are the most important projects done by Ciro Santilli.

Interestingly, the very first programming language with an actual implementation was interpreted: Short Code in 1950.

This is not surprising, as interpreters are easier to write than compilers.

And just like modern scripting languages, it reduced execution speed by about 50x.

Their system is quite good actually. Not as good as a GitHub repo with all the tests made explicit. But still pretty good.
