Today, I’m happy to write about the probably most important C++ Core Guidelines for concurrency rule: Whenever feasible, use tools to validate your concurrent code. Not all, but many bugs can be detected with tools, and each fixed bug is a good bug. Here are two tools that gave me precious help in the last few […]
Writing multithreading programs is hard, even harder if the program should be correct. The rules of the C++ Core Guidelines guide you to writing correct programs. The rules of this post will deal with data races, sharing of data, tasks, and the infamous keyword volatile.
C++11 is the first C++ standard that deals with concurrency. The basic building block for concurrency is a thread; therefore, most rules are explicitly about threads. This changed dramatically with C++17.
I have prepared the pdf bundle. To get it is quite simple.
Today, I will write about the remaining ten rules of performance. Ten rules seem to be a lot, but only two have content.
In this post, I continue my journey through the rules to performance in the C++ Core Guidelines. I will mainly write about design for optimization.
Five bloggers have teamed up worldwide to deliver an April Fool’s joke to readers about eliminating pointers. The response to the five articles was huge and ranged from “it took so long” to “that can not be true”. Here again, the truths, half-truths, and untruths: No New New: Raw Pointers Removed from C++. You can […]
Two weeks ago, the ISO C++ standard meeting took place in Jacksonville. Today I want to make a short detour and write about the revolutionary decision that was made in the Jacksonville meeting. Additionally, I refer to the post C++ Will no Longer Have Pointers by Fluent C++. The standard committee decided that pointers will be […]
Before I write about the rules of performance, I will do a straightforward job. Accessing the elements of a container one by one.
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.
