Delve beneath the runtime. Master pointers, the Rule of Five, RAII, custom arena memory allocators, and lock-free atomic concurrency.
Start your first chapterFree from beginning to advanced. No account needed.New to Python? Begin with stage one. Already comfortable with the basics? Choose a stage and check its entry skills.
Understand bare-metal memory layout, stack vs heap mechanics, pointer arithmetic, and reference semantics.
Start here ifCuriosity about computer architecture and enthusiasm for low-level systems programming.
Suggested entry points, not a placement test. Every lesson is open; move back whenever you need a refresher.
3 modules across 3 stages. Each module shows what you need, what you’ll learn, and a practical self-check before moving on.
Understand bare-metal memory layout, stack vs heap mechanics, pointer arithmetic, and reference semantics.
Basic literacy with terminal tools, compilation concepts, and structured logic.
Navigate memory layouts, pointer dereferencing, and the Rule of Five with absolute confidence.
Pass pointer arithmetic drills and build the custom dynamic String class.
Open the module self-checkMaster Resource Acquisition Is Initialization (RAII), std::unique_ptr, move semantics, and template metaprogramming.
Proficiency in basic C++ classes, constructors, destructors, and pointer fundamentals.
Write leak-free, modern C++ using RAII ownership semantics, smart pointers, and generic templates.
Deliver a functional Arena memory pool allocator benchmarked against standard malloc.
Open the module self-checkHarness C++20 std::jthread, hardware memory ordering, lock-free atomics, and high-performance logging.
Experience with modern C++ move semantics, templates, and basic multi-threaded concepts.
Architect low-latency, multi-threaded infrastructure components using C++20 atomics and ring buffers.
Complete the asynchronous high-speed logger capstone with verified thread-safety.
Open the module self-checkTimes estimate reading only. Make room for coding, practice, and projects at your own pace.
Connect the lessons in 3 guided builds. Use the acceptance checks to review your own implementation, then compare it with the worked example.
A custom dynamic string class managing heap buffers and honoring the Rule of Five.
A high-performance fixed-size block Arena memory allocator bypassing general heap malloc.
An asynchronous high-throughput logging system with a lock-free ring buffer and flusher thread.
A C++20 compliant compiler (GCC 12+, Clang 15+, or MSVC 2022).
Read one example and predict its output before running it.
Use your own Python environment. Change an input and explain the difference.
Attempt the exercises before opening solutions. Use the quiz to find what needs another pass.
Complete the module self-check and note what worked, what failed, and what to revisit.
Compile C++ source files using g++ -std=c++20 or clang++.
Open the setup lessonIf you’re new, follow the sequence. If you’ve used Python before, compare your skills with the stage entry guidance. You can open any lesson and return to earlier topics whenever you need.
Lesson times estimate reading only. Coding, exercises, debugging, and projects take additional time. Completion marks record reading progress on this device; they do not assess proficiency.
The path focuses on core Python and its standard library, including files, objects, tests, concurrency, HTTP, SQLite, and packaging. It provides a foundation for later specialization in web development, automation, or data work.
Only in this browser. They do not sync between devices. You can clear them through Privacy & local data. Quizzes give authored explanations; live AI and accounts are planned.
