one from me: Postel’s Law is wrong it says “be conservative in what you send, be liberal in what you accept” You should be strict on both If you get a bad message, don’t try to guess. Reply with a clear error and stick to the spec https://en.wikipedia.org/wiki/Robustness_principle

DRY (don't repeat yourself) - this mostly because it's so easy to detect duplicates even for beginners. it leads to terribly misguided advice and creating stupid abstractions that complicate the code.

Situational, but “it doesn’t need to look pretty, it just has to work” is pretty bad advice for stuff that needs feedback from nontechnical people. Bad/ugly UX and “it’s just a mock-up” things like dummy data is often very confusing and will often derail user interviews in strange ways

The first question in uni anyone asks when talking about programming is "how many languages do u know" which is bs Doesn't matter after you have picked a few from different levels of the stack

Similar to @ds8's "DRY" is, or can be, bad (through a sophisticated lens) - I'd say the YAGNI ("you ain't gonna need it") cry. Often you ain't gonna need it - but if you really know the space, you can pre-empt patterns, and tackle them. Also, alot of the time (from a learning perspective) you don't know until you try

All of it. Learn why the advice is given in the first place and understand when it makes sense and when it doesn't. Sometimes the advice holds, sometimes it doesn't.

- TS in combination with ES classes are good and should be used often - dependencies are great, don‘t invent everything yourself - you can‘t make money with open source

"Premature optimisation is the root of all evil" is bad advice, you should be aware of performance issues and architect appropriately. Actual good advice is "premature generalisation is the root of all evil"
