[amirkhazama]

2:36 is just pure perfection god I hate confusing internet articles

One of the heroes that created computing and changed the world forever.

Great to see a legitimate women pioneer. Who many girls could see for inspiration as sadly many don't have role models to look up to in comp sci/tech.

Beautiful idea, Maam..
This principle is very important to understand

Without this woman, probably i would not able to write this comment.

[aaronza]

Finally! I understand. Thank you for sharing this video!

Could someone explain how code could even exist without this principle. Moreover, I dont understand how it would be possible to have either a stack or queue as a method parameter without knowing which it is.

Most of my experience is in Java. Perhaps javas rules prevent you from doing this?

Edit: chatgpt gave an answer which I couldn't have thought of.

Say you have a super type Bird. Then a subclass Ostrich. Bird has a method called fly(). In Ostrich yoy would throw an exception because ostriches cant fly.

That is horrible code and i completely see the value of this principle

i don't know why but this is so wholesome

"Behavioral Subtyping" (subtypes behave like supertypes) is much more intuitive than "Liskov Substitution Principle"!!

[JockerTheRipper]

A very simple explanation she said - Behavioural subtyping - subtypes behave like super types 👍👍

[beegdigit]

This is THE explanation from the CREATOR, so sad other videos on this subject have more views

[nickbarton]

How much confusion there is out there about this principle.

[gloverelaxis]

can't understate how happy I was when looking up Liskov Substitution to discover this critical idea was conceived by a woman in this catastrophically male-dominated field. we owe so much to the intelligence of women like Liskov, Hopper and Margaret Hamilton, and we should do everything we can to destroy every last vestige of bigotry in this industry, so everyone feels welcome to explore and improve computing

So ummm. Liskov is woman ?. I tought she is man
