wait-free/lock-free/obstruction-freeの定義について
▲全てに共通する概念
スレッドが他のスレッドの進行を禁止する事がないので、どれかのスレッドが
ロックを確保したままプリエンプションなどで全体の処理が停止する事態が発生しな
い。
これは必ずしもロックベースのアルゴリズムより高速であることを意味し
ない(現にロックの方が早い場合もある
wait-freeが一番強い条件で、それを弱める度に

I will hate you
View hate.markdown

Dear C++ library writer,

  1. If your library forces me to use new all over, I will hate you.

  2. If your library has types with bogus values, I will hate you.

  3. If the documentation for your library gets the terminology of its own domain wrong, I will hate you.

  4. If I say "My God, it's full of stars!" when I see the function signatures in your library, I will hate you.

// Just before switching jobs:
// Add one of these.
// Preferably into the same commit where you do a large merge.

// This started as a tweet with a joke of "C++ pro-tip: #define private public",
// and then it quickly escalated into more and more evil suggestions.
// I've tried to capture interesting suggestions here.
