A new Thread with C++20: std::jthread

One of the participants in my CppCon 2018 workshop asked me: "Can a std::thread be interrupted?". No, was my answer but this is not correct anymore. With C++20 we might get a std::jthread.

A Short Detour: Executors

A few weeks ago, one of the authors of the proposal to the futures in C++ Felix Petriconi wrote me an E-Mail. He said my article about std::future Extensions is quite dated. Honestly, he is right. The future of the futures changed mainly because of executors.

Blocking and Non-Blocking Algorithms

Blocking, non-blocking, lock-free and wait-free. Each of these terms describes a key characteristic of an algorithm when executed in a concurrent environment. So, reasoning about the runtime behaviour of your program often means putting your algorithm in the right bucket. Therefore, this post is about buckets.

Race Conditions versus Data Races

Race conditions and data races are related but different concepts. Because they are related, they are often confused. In German, we even translate both expressions with the term kritischer Wettlauf. To be honest, that is very bad. In order to reason about concurrency, your wording must be exact. Therefore, this post is about race conditions and data races.
