XMLHttpRequest data is subject to this security policy, but sometimes web developers want to intentionally circumvent its restrictions. This is sometimes due to the legitimate use of subdomains as, for example, making an XMLHttpRequest from a page created by foo.example.com for information from bar.example.com will normally fail.
React Native is an open-source UI software framework developed by Meta Platforms (formerly Facebook Inc.). [3] It is used to develop applications for Android, [4]: §Chapter 1 [5] [6] Android TV, [7] iOS, [4]: §Chapter 1 [6] macOS, [8] tvOS, [9] Web, [10] Windows [8] and UWP [11] by enabling developers to use the React framework along with native platform capabilities.

Safely handling undefined values is important in optimistic concurrency control systems, which detect race conditions after the fact. For example, reading a shared variable protected by seqlock will produce an undefined value before determining that a race condition happened. It will then discard the undefined data and retry the operation.
Alternatively, a software authenticator (e.g., implemented on a smartphone) or a platform authenticator (i.e., an authenticator implemented directly on the WebAuthn Client Device) may be used. Relevant examples of platform authenticators include Windows Hello [17] and the Android operating system. [18]
It is the responsibility of the programmer to write code that never invokes undefined behavior, although compiler implementations are allowed to issue diagnostics when this happens. Compilers nowadays have flags that enable such diagnostics, for example, -fsanitize=undefined enables the "undefined behavior sanitizer" in gcc 4.9 [2] and in clang ...
D-Bus (short for "Desktop Bus" [4]) is a message-oriented middleware mechanism that allows communication between multiple processes running concurrently on the same machine. [5] [6] D-Bus was developed as part of the freedesktop.org project, initiated by GNOME developer Havoc Pennington to standardize services provided by Linux desktop environments such as GNOME and KDE.
For example, the imaginary number is undefined within the set of real numbers. So it is meaningless to reason about the value, solely within the discourse of real numbers. However, defining the imaginary number i {\displaystyle i} to be equal to − 1 {\displaystyle {\sqrt {-1}}} , allows there to be a consistent set of mathematics referred to ...
Similar code is usually displayed on infobox pages but it is transcluded from a documentation page and not part of the actual template. Click the "Edit" or "View source" tab on an infobox to get an idea how the source code looks. And see Help:Designing infoboxes. Also, infoboxes are not placed in mainspace but in template space, but if you had ...
