Python is versatile for many tasks like web development and data science.
Using C++ for compute-heavy tasks in Python can boost performance.
Cppyy offers a simple way to integrate C++ code snippets into Python for performance improvements.

In C++, a RAII class like MutexLocker can automate locking and unlocking mutexes, avoiding manual calls.
With MutexProtected in C++, combining mutexes and data types ensures safe mutex access through a callback method.
Combining multiple fields under a single mutex in C++ simplifies concurrency management.

Consider using std::array instead of std::vector when you know the size at compile-time.
Using std::array can provide significant speed improvements over std::vector in certain scenarios.
While std::array is efficient for compile-time initialization and faster than std::vector, it may not be suitable for all cases.

Qt 6 is not yet ready for embedded systems. Many needed features are missing and won't arrive until Qt 6.2, which means developers should stick with Qt 5.15 for now.
C++ property bindings are an exciting new feature in Qt 6. They make code easier to work with by automatically updating properties when related data changes.
Migrating applications from Qt 5 to Qt 6 can be done step by step using the Core5Compat library, which helps manage outdated classes and reduce errors during the transition.

The article discusses the 'memfd' library as an example of Foreign Function Interface (FFI) in Haskell.
It references Drew DeVault's book 'The Wayland Protocol' for illustrating shared memory allocation.
