Most active GitHub users (git.io/top)

The list would not be updated for now. Don't write comments.

The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at GitHub.com from Wed, 21 Sep 2022 till Thu, 21 Sep 2023.

Because of GitHub search limitations, only 1000 first users according to amount of followers are included. If you are not in the list you don't have enough followers. See raw data and source code. Algorithm in pseudocode:

Communicate between objects using channels

When you have two objects A and B, say two view controllers, that you want to have talk to each other, you can choose from the following options:

• NSNotificationCenter. This is anonymous one-to-many communication. Object A posts a notification to the NSNotificationCenter, which then distributes it to any other objects listening for that notification, including Object B. A and B do not have to know anything about each other, so this is a very loose coupling. Maybe a little too loose...

• KVO (Key-Value Observing). One object observes the properties of another. This is a very tight coupling, because Object B is now peeking directly into Object A. The advantage of KVO is that Object A doesn't have to be aware of this at all, and therefore does not need to send out any notifications -- the KVO mechanism takes care of this behind the scenes.

• Direct pointers. Object A has a pointer to Object B and directly sends it messages when something of interest h
