C++20 concepts make template requirements explicit, reusable, and easier to diagnose. This article explains how concepts improve generic code, participate in overload resolution, simplify class template specialization, and help build a clear vocabulary for type requirements.
Getting an interview invitation in 2026 is not only about sending more applications. This article explains why direct applications often work poorly, how recruiters search for candidates, and how proper LinkedIn positioning can make your profile easier to find and understand.
C++ ranges and views make traversal code safer and more expressive by replacing manual iterator pairs with higher-level sequence abstractions. This article explains where iterator-based APIs become error-prone, how ranges reduce those risks, and why lifetime still matters.
A practical look at common CMake mistakes that make build configuration fragile: overloaded CMakeLists.txt files, manual compiler flags, ignored CTest infrastructure, unnecessary custom logic, and global commands that break target boundaries.
C++ compiles many mistakes that are still expensive. This article shows how `clang-tidy` helps catch subtle language misuse early — and how to introduce it into a real project without chaos.
A practical C++ learning path: what to learn first, what to postpone, and how to build real skills through one project.
Unit tests don’t have to be a “big rewrite.” This article shows a practical way to introduce unit tests into an existing C++ project: integrate GoogleTest with CMake/CTest, start with isolated code, scale with fixtures, and mock external dependencies without turning your codebase upside down.
* Manual resource management is fragile and exception-unsafe.
* RAII makes cleanup automatic and reliable.
* Prefer standard RAII types: `std::unique_ptr`, `std::lock_guard`, `std::fstream`, containers.
* Aim for the **Rule of Zero**: let RAII members define correct destruction and ownership.
Adding std::mutex does not automatically make C++ code thread-safe. This article breaks down three practical rules for using std::mutex safely: rely on RAII, keep synchronization boundaries explicit, and treat std::recursive_mutex as a design smell before treating it as a solution.
A technical interview can feel chaotic: time pressure, unfamiliar people, and the need to explain your thinking clearly. This article turns that complexity into a simple C++ interview framework: what interviewers evaluate, how to communicate, how to manage time, and what “clean modern code” should look like under pressure.
