Programming

The Curiously Recurring Template Pattern (CRTP)

Master the CRTP in C++ — learn static polymorphism, mixin classes, compile-time interface enforcement, and how CRTP eliminates virtual function overhead with clear examples.

Placement New and Memory Pools

Master C++ placement new — learn how to construct objects in pre-allocated memory, build memory pools, manage object lifetimes manually, and avoid common pitfalls.

Custom Memory Allocators in C++

Learn C++ custom memory allocators — why the default allocator is slow for some workloads, how to write STL-compatible allocators, pool allocators, arena allocators, and when to use each.

Understanding the C++ Memory Model

Master the C++ memory model — learn happens-before, sequentially consistent execution, data races, memory ordering, and why your multithreaded code needs more than just atomics.

Atomic Operations in C++: Lock-Free Programming

Master C++ atomic operations — learn std::atomic, memory orders, compare-exchange, lock-free data structures, and when atomics beat mutexes for performance.
