Рабочий прототип, вместо полезной нагрузки резистор TL;DR: здесь ноль медицины и нейробиологии, только инженерный разбор прототипа DIY tRNS: архитектура, генерация сигнала (100–640 Гц hf-tRNS), VCCS,...

3D рендер модели модуля Привет, Хабр! Так уж сложилось, что 99% устройств моего «умного дома» были спроектированы и собраны самостоятельно — что тут поделать, каждый развлекается как может. Об одном...

Вычисление обратной матрицы квадратной матрицы высокого порядка, а именно, вычисление алгебраических дополнений и определителя матрицы займёт большое количество машинных ресурсов. Поэтому обращение...

Весь год мы скакали по бескрайним полям открытого кода, расследуя преступления, отстреливая уязвимости и собирая трофеи. Но сегодня мы решили заглянуть в самый пыльный бар, где у стойки стоит опытный...

I wanted my program to boot up faster so I tried to multithread it with both executors and the more classic TBB.

Last time we explored some commonly found alternatives to using enums for error codes such as asserts, contracts and std::expected. Finally today we consider some unthinkable options.

Let’s talk about game simulations. Today we dive into the nitty-gritty bits of implementing data driven multi-threading.

Looking back at 2025 and looking forward to 2026 through the lens of graphics programming.

The Kona WG21 meeting was two weeks ago. This was the (first) big “resolve NB comments for C++26” meeting.
Last month I wrote about some of the NB comments, and whether they might
actually lead to removal of the offending features. Well, big news: P2786’s…

This afternoon I presented a paper at the quarterly meeting of the “Three Garridebs,”
Westchester’s scion society of the Baker Street Irregulars. Here it is for
posterity, almost entirely as delivered (minus a brief ad-lib apology for its being
more about…

C++20 added atomic_ref<T> to the Standard Library (see
“Guard nouns or guard verbs?” (2023-11-11)).
But somehow C++20 overlooked atomic_ref<const T>; it’s finally permitted in C++26,
thanks to Gonzalo Brito Gadeschi’s P3323.
But then there was a new problem:…

In C++, when we have a type that carries no data — whose only “identity” is its type —
we conventionally call that a “tag type.” When you see code like struct X {}; it’s
often the case that X is a tag type. However, not all tag types are created equal:
there…

Big news of the week, via Hacker News:
Someone has engineered
a 1D spaceship
in Conway’s Game of Life! That is, there exists a pattern which initially fits
into a bounding box of dimensions \(3\,707\,300\,605\times 1\) — that “1” is what makes it
“1D” — and…

Lately libc++ has been adding the C++17 [[nodiscard]] attribute aggressively to every header.
(I’m not sure why this month, but libc++ my guess is that they just dropped support
for some old compiler such that all their supported compilers now permit the…

Back in 2021 I announced the rediscovery of a text
adventure named Castlequest (Mike Holtzman and Mark Kershenblatt, 1980).
This month another “lost game” has been found: David Long’s 751-point Adventure!

Previously: “LONG0751 has been found!” (2025-12-29).
This post contains partial/minor spoilers for LONG0751!

I had a vague idea that closures could have a variety of performance implications; I did not believe that so many of the chosen and potential designs for C a...

The last article checked the landscape of various C and C extension implementations of Closures for their performance capabilities. But, there were a few twe...

Back before C++11, the recommended way to customize the behavior of an algorithm was to write a functor-struct, e.g. a small struct overloading operator(). E.g. for sorting by a specific key: struc…
