Filip Hráček discusses the complexities of categorizing open source software, arguing that it cannot simply be viewed as a binary distinction of "open source" or "not open source." He highlights the significant variations in quality and backing among open source projects, using examples like the Android SDK and random npm packages, or VS Code versus personal GitHub projects. Hráček notes that traditional taxonomies such as "professional vs. amateur" or "commercial vs. non-commercial" do not effectively classify these

The new `window.setMainMenu(menu)` function allows developers to create a native window menu for GNU/Linux and Windows, and an application menu for macOS. Developers can call this function multiple times to dynamically update menu items. When a user clicks a menu item, the framework triggers a `mainMenuItemClicked` event with the relevant data. On macOS, key accelerators and pre-defined actions can be registered, but currently, GNU/Linux and Windows only display keyboard shortcuts within menu items without registering

In his article, Gustavo Noronha discusses the advantages of Rust over C++ in creating user-friendly and safe APIs, particularly in relation to avoiding common mistakes such as argument swapping. He was inspired by a talk from Matt Godbolt that emphasized making C++ interfaces robust through "Correct by Construction" principles. Noronha notes that while C++ has a long history, Rust benefits from modern design lessons. He illustrates his points with an example from Godbolt's talk, which addresses issues in a shader compilation class
