standard passed ISO voting, expected to be formally published by the end of 2020.4 Agenda  Modules  Ranges  Coroutines  Concepts  Lambda Expression Changes  [=, this] as Lambda Capture   co_yield  char8_t  New identifiers:  import  moduleModules7 Modules  Advantages  Replace header files  Modules explicitly state what should be exported (e.g. classes, functions, …) names, same name in multiple modules will not clash  Modules are processed only once  faster build times  Preprocessor macros have no effect on, and never leak from, modules  Order of module imports

Everything Runs on UI Thread* • Plugins created with native code • React Support • API Access via Native Modules • UI Thread vs JS Thread • Angular/Vue/Vanilla vs React • Progress vs Facebook • Apache 2.0 vs native APIs still available at JavaScript layer for platform-specific scenarios o NativeScript modules follow Node module conventions (CommonJS) Example: NativeScript file module BUT HOW DO I TURN Pages/Views o XML markup structure o Elements (e.g. , ) are NativeScript modules NativeScript Modules for UIs UI Widgets o Button o Label o TextField o TextView o SearchBar o Switch o Slider

/usr/share/cmake/Modules 。 • 包搜索文件可以在不知道包具体位置信息的情况下搜索他们（在 /usr/lib 等默认路径搜 索）。 • 这些都是 CMake 自带的包搜索文件： • /usr/share/cmake/Modules/FindCUDAToolkit.cmake • /usr/share/cmake/Modules/FindPython.cmake find_package(TBB MODULE REQUIRED) • 只会寻找 FindTBB.cmake ，搜索路径： 1. ${CMAKE_MODULE_PATH} （默认为 /usr/share/cmake/Modules ） • find_package(TBB CONFIG REQUIRED) • 只会寻找 TBBConfig.cmake ，搜索路径： 1. ${CMAKE_PREFIX_PATH}/lib/cmake/TBB

More components will be open source later • Support more Linux distributions • Build IPVS kernel modules in Ubuntu, Centos • IPVS-eBPF next generation on the way • Implement IPVS SNAT with eBPF without
