  • [2014/06] Scott Meyers: Why C++ Sails When the Vasa Sank

    • 講述 C++ 這一路走來，讓它持續有許多使用者的重要特色，以及近年來如何變得更好

    • 讓舊有的程式碼依然可以編譯，加入新 feature 讓同樣的 code 可以更簡單易懂
      • 20 年前的程式依然可以 compile
    • You don’t pay for what you don’t use.
      • 編譯時期把不必要的東西去掉 (pay at compile time, not runtime)

    • C : Trust the programmer

    • 和 C 有一定的相似度，所以 C programmer 的一些知識在這邊也同樣用的上

    • C++ 有良好的效能，也適用於只能用較少的硬體和能源但同時也需要效能的情況 (embedded)

    • perfect forwarding 可以避免 temporary object 的產生

    • std::forward

    • type traits : std::remove_reference, std::enable_if

    • std::make_shared

    • moving is not free, it’s typically cheap, but it’s not always cheap, and it more expensive then binding to a reference

    • perfect forwarding is not perfect, but it’s really really good

    • something can’t perfect forwarding
      • 0 as null pointer constant
      • Braced initializer lists
      • Integral const static class members lacking a definiton
      • Template names (e.g., std::endl)
      • Non-const lvalue bitfields
