My original plan was it to write in this post about the next rules to error handling. But I changed my plan to write about the future: contracts in C++20.

Error handling is an important part of writing good software; therefore, the C++ core guidelines has about 20 rules for error handling.

Now, it's time to choose the next pdf bundle? You will get all posts, all source files, and a cmake file to the chosen topic.

Today, I will finish my story to concurrency and lock-free programming in particular. There are four rules to lock-free programming in the C++ core guidelines left.

Today, I solve the riddle from my last post. Thanks to my readers, the analysis of the ABA problem is quite accurate.

Today, I finish the rules to concurrency and continue directly with lock-free programming. Yes, you have read it correctly: lock-free programming.

After the last post to executors, I can now finally write about the unified futures. I write in the post about the long past of the futures and end my detour from the C++ core guidelines.

The update of my book "Concurrency with Modern C++" is available. This version is a total rework of the previous one and includes also new sections such as for executors. In total, the book is 60 pages bigger.

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.
