CORE DEFINITION

Feature toggle, also known as feature switch, feature flag, feature flipper, or conditional feature, is a technique in software development that serves as an alternative to maintaining multiple source code branches (also known as feature branches). It allows features to be tested before they are completed and officially released. Feature toggles hide, enable, or disable specific features during runtime. For example, during development, developers can enable a feature for testing while other users are not affected by it. Continuous release and continuous delivery provide developers with rapid feedback on their code, which requires early integration of code changes. Feature branches introduce a bypass to this process. Feature toggles are an important technique for achieving continuous delivery. This technique allows developers to release product versions that contain unfinished features. These unfinished features are hidden or disabled, so they do not appear in the user interface. This allows software to be released in many small incremental versions without the cost of constant branching and merging.

Anchor fast decisions

When software goes live, first let a small portion of users/traffic use the new version, verify stability and metrics in the real environment, then gradually expand the proportion to full rollout, to control the blast radius of failures.

A local crackdown or restriction may shift activity to other places or channels; distinguish a local decrease from an overall decrease.

Sherlocking

Sherlocking refers to the phenomenon where a platform owner copies the features of a third-party developer's app and integrates them into the platform, thereby rendering the third-party app obsolete. The term originates from Apple's Sherlock search tool, which was introduced in Mac OS 8.5 and later incorporated features similar to those of third-party search utilities like Watson, leading to the coining of the term.

Beat Frequency

The term "beat note" or "beat frequency" originates from acoustics, referring to the interference of two sound waves with similar but different frequencies. The resulting interference signal has a frequency equal to the absolute difference between the two original frequencies, hence the name. This concept is also applied in optics and electronics, where combining two signals of different frequencies yields a new signal with a frequency equal to their difference. For example, consider two sine waves with equal amplitude, no phase difference, but slightly different frequencies.
