So I have an oddly specific question: Is it possible to generate a code without necessarily knowing what service I am using? For example, let’s say I use Google Authentication and I am trying to get a code for “MyRandomWebsite”. I assume Google can see that I’m trying to access “MyRandomWebsite”, what time, whose account it is etc etc. My question is, do we have technology where the authenticator (eg Google Authenticator) and the service (MyRandomWebsite) don’t know who’s using trying to access what website?
Okay ;) C++ allowed for multiple class inheritance and deciding which general behaviour to inherit is easily solved there. Go figure ha?! But you got the main difference correctly.
Note for myself Summary:- Abstract Class: To generalize behavior. Interfadce: To standarize. It is a contract that the object should be having this much things. Although we can now have methods in both, purpose of the methods in both case is different. Interface methods were interoduced to not break existing implementations. Also, All variables in interface are public+static+final while in abstract class thats not the case. So all members of implemented/extended class will have same/different copies in interface/class respectively. There isnt other difference I think, still feel free to comment and discuss
Not a Node programmer, but came here to learn a little more about epoll for my thesis. And what a great video, you did an amazing job explaining non-blocking I/O and the epoll syscall, congrats man! Btw, are you Brazilian? I couldn't tell by the accent.
Because then each file would create a new metric with a single data point, after a while this would really wreck your performance and you’d need to accommodate for this in your queries. Labels have to have a low cardinality
@@Gabzim labels are used like that in loads of places though, and pretty common right? e.g. node exporter, so it is possible, but like with all prometheus metrics, you just have to be wary of cardinality - though it feels like the same could be said when comparing to some downsides of SQL based systems - just feels like in this case its maybe a bad example to give of something you can't do in prometheus, when you can? Side note - really like your drawings, it fits in really well with the video as you explain stuff.
You don't have to explain it to javascript developers, because javascript developers usually think you are trying to take their job if you even try to learn javascript as a C/C++ developer. Many javascript developers have said that i do not know javascript, but i was just trying to learn and that i should go back to my C/C++, so no you should not help javascript developers to learn.
Oh man, thank you so much. I've been in this rabbit role trying to understand where does the async execution in node ends and I wasn't happy that all the previous content I consumed ended at the libuv. I knew that there was an Operating System calls being made but I wasn't sure how did they called the callbacks on libuv. Thank you for this video!
