Empowering everyone to build reliable and efficient software.

We discuss how to make sure that your access to TLS (thread-local storage) is fast, and how the presence of constructors and shared libraries affects the access time.

We introduce a new C++ function tracing profiler, and discuss how to use such a profiler, how to make one for native code, and how a simple CPU hardware feature can make tracing very cheap for compiled, interpreted and JITted languages

On Saturday, the ISO C++ committee completed the second-last design meeting of C++26, held in Hagenberg, Austria. There is just one meeting left before the C++26 feature set is finalized in June 20…

原标题：“A calculator app? Anyone could make that” 这篇文章探讨了开发计算器应用的复杂性，挑战了“任何人都可以做一个计算器应用”的说法。虽然表面上看，计算器似乎很简单，但实际上要保证其提供正确的数学结果却困难重重。 文章首先指出，许多计算器（如iOS计算器）在处理大数字时会出现错误。例如，(10^100) + 1 − (10^100) 的应该结果是1，而不是0。与之相对，Android的实现则是正确的。为了解决这个问题，Google聘请了知名开发者Hans-J.…

Here is a rough approximation of float multiplication (source): float rough_float_multiply(float a, float b) { constexpr uint32_t bias = 0x3f76d000; return bit_cast<float>(bit_cast<uint32_…
