    Directly accessible TV/radio icon library and related tool projects

    LIVE is an open-source Chinese television and radio logo library with related IPTV utility resources. The project provides directly accessible TV and radio icon paths that can be used in playlist, player, and electronic program guide workflows.

It also exposes an EPG interface and web tools for tasks such as M3U8 downloading and format conversion.

    Retire.js

    Retire.js

    Scanner detecting the use of JavaScript libraries

    There is a plethora of JavaScript libraries for use on the web and in node.js apps out there. This greatly simplifies, but we need to stay updated on security fixes. "Using Components with Known Vulnerabilities" is now a part of the OWASP Top 10 and insecure libraries can pose a huge risk for your web app. The goal of Retire.js is to help you detect the use of versions with known vulnerabilities. Scan a web app or node app for use of vulnerable JavaScript libraries and/or node modules. grunt-retire scans your grunt-enabled app for use of vulnerable JavaScript libraries and/or node modules. Scans visited sites for references to insecure libraries and puts warnings in the developer console. An icon on the address bar displays will also indicate if vulnerable libraries were loaded. Retire.js has been adapted as a plugin for the penetration testing tools Burp and OWASP ZAP.
