#cplusplus#cross_platform Lynx is an open-source framework that lets you build native mobile and web apps using web skills like CSS and React from a single codebase. It delivers true native performance through a dual-threaded architecture that separates UI rendering from business logic, eliminating lag and enabling instant app launches. This means you can write code once and deploy across Android, iOS, and web platforms, saving development time and costs while maintaining the speed and responsiveness of native applications. https://github.com/lynx-family/lynx

How #Django knows to #UPDATE vs. #INSERT when you call #save (), #Django follows this algorithm: If the object’s primary key attribute is set to a value that evaluates to True (i.e., a value other than None or the empty string), Django executes an UPDATE. If the object’s primary key attribute is not set or if the UPDATE didn’t update anything, Django executes an INSERT.
