My Next Mentoring Program: “Generic Programming (Templates) with C++” startsFebruary 4, 2025 - 4:51 pm
My next mentoring program, “Embedded Programming with Modern C++,” starts on January 31st. Registration is open. Here are more details. Embedded Programming with Modern C++ The mentoring program consists of 16 stations. You have to invest at least 3 hours per week for each one. This means the program takes four months, and you can […]
A Lock-Free Stack: A Simplified ImplementationFebruary 3, 2025 - 10:37 am
Today, I continue my mini story about lock-free data structures. General Considerations From the outside, the caller’s responsibility (application) is to protect the data. From inside, the data structure is responsible for protecting itself. A data structure that protects itself so a data race cannot appear is called thread-safe. First, what general considerations must you […]
Deferred Reclamation in C++26: Read-Copy Update and Hazard PointersJanuary 27, 2025 - 12:23 pm
Before I dive into lock-free programming, there’s a little bit of theory necessary. A common problem in concurrency is the so-called ABA problem. That means you read a variable twice, which returns the same value each time, A. Therefore, you conclude that nothing changed in between. But you forgot the B. Let me first use […]
std::format ExtensionJanuary 20, 2025 - 11:55 am
Displaying the address of an arbitrary pointer in C++ 20 fails but succeeds with C++26. C++20 Only void, const void, and std::nullptr_t pointer types are valid. If you want to display the address of an arbitrary pointer, you must cast it to (const) void*. // formatPointer20.cpp #include <format> #include <iostream> #include <string> int main() { […]
C++26 Library: string and string_view ProcessingJanuary 13, 2025 - 11:42 am
C++26 offers many small improvements around strings and string_views. First of all: What is a string_view? std::string_view A std::string_view is a non-owning reference to a string. It represents a view of a sequence of characters. This sequence of characters can be a C++ string or a C-string. In a typical way, C++17 offers four type […]
