📅 7 Practical std::chrono Calendar Examples (C++20)
An insightful and hands-on guide for modern C++ developers, this post connects C++20’s `<chrono>` concepts with real scheduling and financial date logic, making it a valuable read for those working on time-sensitive systems.
This article presents seven concise examples demonstrating how to use C++20’s `<chrono>` calendar utilities in real-world applications. It explains computing the day of the year, finding specific weekdays, handling end-of-month logic, adding months correctly, and identifying business days. It highlights the difference between calendar-based and duration-based operations and how `sys_days` supports normalization and reliable date arithmetic.

🧠 runST Does Not Prevent Resources from Escaping
A compelling read for those exploring the boundaries of type safety, this article exposes how seemingly airtight functional abstractions can be undermined through clever type-level manipulation, offering valuable lessons for compiler and language design enthusiasts.
This in-depth analysis reveals how Haskell’s `runST` function, designed to enforce purity and prevent leaks, can still be circumvented under certain type constructions. Through examples, it shows how existential types and wrapping can break the expected safety, leading to resource misuse. It also clarifies the internals of `runST`, showing that its safety relies on compile-time tagging of `STRef`s rather than runtime enforcement.
