-- [c++ tip of week ](https://github.com/QuantlabFinancial/cpp_tip_of_the_week/)
+- [What is the “vector pessimization”?](https://quuxplusone.github.io/blog/2022/08/26/vector-pessimization/)
 
-`TODO fix link then remove this line`
+尽量让move 构造函数 noexcept， 不然用vector可能有问题，多copy
 
+比如这个
+```cpp
+struct Instrument {
+ int n_;
+ std::string s_;
 
+ Instrument(const Instrument&) = default;
 
+ // WRONG!!
+ Instrument(Instrument&& rhs)
+  : n_(std::exchange(rhs.n_, 0)),
+  s_(std::move(s_))
+  {}
 
+ // RIGHT!!
+ Instrument(Instrument&& rhs) noexcept
+ : n_(std::exchange(rhs.n_, 0)),
+ s_(std::move(s_))
+ {}
+};
+```
 
+如果不是noexcept，vector的move判定内部的T不是is_nothrow_move_constructible, 那就构造复制一份，所以多了个拷贝。也就是博主说的vector pessimization问题
 
+vector本身的搬迁move的多余动作，如果能nothrow，move就更简单
 
+- [malloc() and free() are a bad API](https://www.foonathan.net/2022/08/malloc-interface/#content)
 
+free没有size看上去是个巧妙的设计，实际上隐含了挺多脏活

-- [C++ Weekly ](https://www.youtube.com/channel/UCxHAlbZQNFU2LgEtiqd2Maw)
+有点意思
 
-`TODO fix link then remove this line`
+```cpp
+struct foo {
+ [[nodiscard]] foo(auto& resource) {}
+};
 
+struct [[nodiscard]] bar {};
 
+auto fn() -> bar;
 
+[[nodiscard]] auto fn2() -> bool;
 
+int main(int, char** argv){
+ foo{argv}; // ignoring temp created by [[nodiscard]]
+ fn(); // ignoring return value with [[nodiscard]]
+ fn2(); // ignoring return value with [[nodiscard]]
+}
+```
+- [Do we need the Y-combinator in C++? ](http://ib-krajewski.blogspot.com/2017/10/do-we-need-y-combinator-in-c-and.html?m=1)
 
+老文，科普一下概念。
 
+- [constexpr Function Parameters](https://www.elbeno.com/blog/?p=1685)
 
+参数不是constexpr
+```cpp
+consteval auto square(int x) -> int { return x * x; }
 
+constexpr auto twice_square(int x) -> int { return square(x); }
+```

+编译不过。作者展示了一下编译期计算。哎又回去了。constexpr还是不够const

+- [C++ Weekly - Ep 339 - `static constexpr` vs `inline constexpr`](https://www.youtube.com/watch?v=QVHwOOrSh3w)
+
+static constexpr 和 inline constexpr区别。inline constexpr能合并文件重复的数据，是文件级别，static是函数级别，并不能合并代码段
+
+聪明的你想到了static inline constexpr。这个效果就是static constexpr。static限制了范围
