AddLarge Scale Automated Refactoring.
OpenRewrite is an open-source automated refactoring ecosystem for source code, enabling developers to effectively eliminate technical debt within their repositories.
It consists of an auto-refactoring engine that runs prepackaged, open-source refactoring recipes for common framework migrations, security fixes, and stylistic consistency tasks – reducing your coding effort from hours or days to minutes. Build tool plugins like the OpenRewrite Gradle plugin and the OpenRewrite Maven plugin help you run these recipes on one repository at a time.

At its core, localStorage is a simple key-value store which uses strings as keys and can only store strings as values. Even if you try to store a non-string object into localStorage, it will be converted into a string before it is saved. This means that the developer has to worry about coercing the data back into the intended type before it is used in code again. Still, localStorage's ability to save data between sessions and browser restarts without relying on massive cookies makes it an appealing storage mechanism.

OpenSSF Scorecard assesses open source projects for security risks through a series of automated checksIt was created by OSS developers to help improve the health of critical projects that the community depends on.
You can use it to proactively assess and make informed decisions about accepting security risks within your codebase. You can also use the tool to evaluate other projects and dependencies, and work with maintainers to improve codebases you might want to integrate.
Scorecard is an automated tool that assesses a number of important heuristics ("checks") associated with software security and assigns each check a score of 0-10. You can use these scores to understand specific areas to improve in order to strengthen the security posture of your project. You can also assess the risks that dependencies introduce, and make informed decisions about accepting these risks, evaluating alternative solutions, or working with the maintainers to make improvements.

- Mission: Maintain an open standard for UI and promote its adherence and adoption.
- Audience: The broader UI community including designers, engineers, and managers.
The purpose of Open UI to the web platform is to allow web developers to style and extend built-in web UI controls, such as <select> dropdowns, checkboxes, radio buttons, and date/color pickers. To do that, we'll need to fully specify the component parts, states, and behaviors of the built-in controls, as well as necessary accessibility requirements, and provide test suites to ensure compatibility. We'll also implement polyfills for our extensible web UI controls.
