In Java, an annotation is a form of syntactic metadata that can be added to Java source code. It provides data about a program that is not part of the program itself. Annotations have no direct effect on the operation of the code they annotate. Classes, methods, variables, parameters and packages are allowed to be annotated.

This topic illustrates how to avoid adding unwanted files (or file changes) in a Git repo. There are several ways (global or local .gitignore, .git/exclude, git update-index --assume-unchanged, and git update-index --skip-tree), but keep in mind Git is managing content, which means: ignoring actually ignores a folder content (i.e. files). An empty folder would be ignored by default, since it cannot be added anyway.

Local notifications allow your app to notify the user about content which does not require the use of a server.

Unlike remote notifications which are triggered from a server, local notifications are scheduled and triggered within an app. Notifications in general are targeted to increase user interaction with the app, inviting or tempting the user to open and interact with it.

UILocalNotification was deprecated in iOS 10. Use the UserNotifications framework instead.

Every browser has a default set of CSS styles that it uses for rendering elements. These default styles may not be consistent across browsers because: the language specifications are unclear so base styles are up for interpretation, browsers may not follow specifications that are given, or browsers may not have default styles for newer HTML elements. As a result, people may want to normalize default styles across as many browsers as possible.
