SOLID Revisited : The State of the Matter - Phil Nash - NDC Oslo 2021

The SOLID principles were first grouped together by Robert Martin over two decades ago - but the principles themselves are much older. A solid basis for good design (pun intended)? Perhaps. But in recent years there has been increasing talk that they are internally redundant, too focused on OO, or just missing the mark in other ways.
So are they still useful? Is it worth teaching them? Is there a better set to go by? Do we need a new acronym, perhaps referencing a different state?
After a brief history, and a refresher on what the SOLID principles actually are, we’ll weigh up some of the criticisms that have been levelled by others, maybe add some new ones, then look at some ideas for a way forward. Bring your opinions - let's have a bit of a discussion, too!

Tank you for the interesting talk. Robert C Martin published an article on his blog in october 2020 in response to Dan North's position on SOLID (the article is called "Solid Relevance"). Could it be interesting to also have it analysed in this talk?

I seems like this boring talk picks the words apart without understanding the meaning, and misses all the points of what it tries to analyze. Not understanding what is the meaning of the word "principle" in the context, or what is morals in general, really makes it look helpless.

If your modifications start having a switch statement to deal with different cases, you are violating Open/Closed.

I don't really understand the point of this talk. It does not seem to be about anything. He just seems to make vague observations about SOLID. Odd. I can see why my company never permits me to go to NDC. Seems like I'm not missing much.

[@BryonLape]

Absolute worst straw man argument I've ever seen. Kevlin did a much better job breaking down SOLID and proposing some overlap. Phil meanders around in small circles and never accomplishes anything resembling an argument.

[@bocckoka]

He should really do something about his breathing difficulty.

[@BryonLape]

Losing 3 stone would help.

[@mishasawangwan6652]

utter nonsense

[@BryonLape]

The world is doomed to have programmers who really do not what they are doing, but produce code that is (mostly) working, though maintenance is costly.

[@17plus9]

Useless talk, waste of time.
