These binaries are licensed under the MIT license. Telemetry is disabled. If you want to build from source yourself, head over to Microsoft’s vscode repo and follow their instructions. VSCodium exists to make it easier to get the latest version of MIT-licensed VSCode.

    compromise

    compromise

    Modest natural-language processing

    Language is complicated and there's a gazillion words. Compromise is a javascript library that interprets and pre-parses text and makes some reasonable decisions so things are way easier. Compromise tries its best to parse text. it is small, quick, and often good-enough. It is not as smart as you'd think. Conjugate and negate verbs in any tense. Play between plural, singular and possessive forms. Interpret plain-text numbers. Handle implicit terms. Use it on the client-side or as an es-module. compromise is 180kb (minified). It's pretty fast. It can run on keypress. It works mainly by conjugating all forms of a basic word list. Decide how words get interpreted or make heavier changes with a compromise-plugin. Parse text without running POS-tagging. Pre-parse any match statements for faster lookups. It is not the most accurate, or clever nlp library, but found its niche as an easy, small library that can run everywhere.

    Atom Linux

    Atom Linux

    The hackable text editor

    Atom is a hackable text editor for the 21st century, built on Electron, and based on everything we love about our favorite editors. We designed it to be deeply customizable, but still approachable using the default configuration. A set of encrypted code signing certificates were exfiltrated; however, the certificates were password-protected and we have no evidence of malicious use. As a preventative measure, we will revoke the exposed certificates used for the Atom application. Revoking these certificates will invalidate some versions of Atom. When we introduced Atom in 2011, we set out to give developers a text editor that was deeply customizable but also easy to use—one that made it possible for more people to build software. While that goal of growing the software creator community remains, we’ve decided to retire Atom in order to further our commitment to bringing fast and reliable software development to the cloud via Microsoft Visual Studio Code and GitHub Codespaces.
