This week there’s a ISO C++ meeting in Cologne, and after having the Spanish national body meeting this past week this looks like a perfect moment to reflect, one more time, on reflection in C++. 1. Scope 2. Motivation 3. Minimal intro to the Reflection TS…

Теме компилятора ключевая в этом проекте. Я позже её более подробно опишу, но сейчас в дополнение к крестам. Мир Не думаю, что здесь не...

With C++17’s constexpr functions and C++20’s consteval specifier, it is easy to do compile-time calculations using templates and use them at run-time.

The amortized cost of vector insert is 3 C++ requires many algorithms to be implemented in amortized constant time. I was curious about what this meant for vector insertion. To get started I first wrote an article about amortized time in general. Now I'd…

Variants are data types that can store different types of values in them, as opposed to one fixed type. In contrast to a generic object or an untyped variable, there is a limited number of storable types. I use these in my Leaf compiler in two key places:…

Mathew Benson joins Phil and Timur. After some news on new dev tool releases and some welcome improvements to iostreams in GCC13, we talk to Mathew Benson about what it's like to learn and use C++ in Africa and the implications for the hardware and our choices…

This article describes an interesting overflow bug in the ELF hash function. The System V Application Binary Interface (generic ABI) specifies the ELF object file format. When producing an executable

This is a continuation of yesterday’s post, “std::format from scratch, part 2.”
We’ve already seen how to specialize std::formatter<Widget> so that we can
std::format("{}", w), and how to implement format specifiers so that we can
std::format("{:a}", w).…

Добавляем функциональность к музыкальному MIDI-синтезатору на двух чипах AY-3-8910, а также вспоминаем, что общего между музыкой и математикой. Оглавление Dual AY-3-8910 MIDI module Принцип работы...

В этой статье я расскажу об одном способе вычисления x mod p, для p вида (2 ** n - omega), причём omega значительно меньше 2 ** n. Напишу генератор констант на Python. Приведу пару игрушечных примеров...

More focus on customer experience necessitates the use of analytics. Freemium business models can only be optimized with analytics. Consumer segmentation can be augmented with analytics. The success of customer activation activities can only be proven with…

Last time I showed a couple of questions about initialization. Try them here if you haven’t already. In this article, I’ll show you the answers and add more notes about initialization in C++.
About   I selected the following questions from 25 questions that…

UNDER CONSTRUCTION This article describes target-specific details about AArch32 in ELF linkers. I described AArch64 in a previous article. AArch32 is the 32-bit execution state for the Arm architectur

Software developers and managers know how complex and wearing it is to deliver a product that just feels like a natural extension of our senses and abilities. And they know even better that the choice of the right tools for a given task makes the real difference.…

Let me tell you a story about how Windows users are deleting files from their installation and as a consequence end up in tears. Background The real and actual curl tool has been shipped as part of Windows 10 and Windows 11 for many years already. It is called…

The compiler is already making compile-time assumptions about the processor; you just don't realize it.
