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_…

I've done a shallow clone of a large repo (git clone --depth 1 git@github.com:myOrg/myRepo.git). I can push new changes to the remote but the first push is horribly slow. Subsequent pushes are fine...

A young computer scientist and two colleagues show that searches within data structures called hash tables can be much faster than previously deemed possible.

With the recent GNU Binutils 2.44 release, one of the changes is worth calling out in its own article: the GNU Gold linker is now officially deprecated and is now being segregated to its own extra Binutils package but risks being removed all together without…
