Rust прячет инструменты там, где вы их не ищете. Часть 3
Привет, Хабр! Знакомая история: пишешь код, всё работает, ревью прошло, поехали дальше. А через какое-то время натыкаешься в документации на метод, который делал ровно то же самое — в одну строку, без твоего велосипеда на десять. И остаётся только вздохнуть: ну где ж ты был раньше! Со стандартной библиотекой Rust так постоянно. Она большая, и половину её мы не используем не потому, что она плохая, а потому, что просто про неё не знаем — и пишем руками то, что давно лежит готовым. В первой части уже разбирали такие штуки: never-тип ! , matches! , black_box , прозрачные обёртки repr(transparent) и transmute_copy . Подготовил для вас ещё девять.

sizeof(Mutex<()>) упал с 40 байт до 5: что внутри std::sync::Mutex после Rust 1.62
sizeof(Mutex<()>) в Rust 1.61 на Linux был 40 байт. В Rust 1.62 он стал 5 (точнее, 8 с учётом выравнивания, но базовый overhead 5). За уменьшением размера в восемь раз стоит полная переписка стандартного Mutex с pthread на futex напрямую, ускорение uncontended locks в 2-3 раза, и десятилетие, которое стандартный Mutex провёл в роли «возьми parking_lot, std::sync::Mutex медленный». Сегодня заглянем под капот всей этой темы, разберём, что лежит внутри std::sync::Mutex после 1.62, какой алгоритм там используется, почему он на самом деле быстрее pthread, как устроен fairness (точнее, его отсутствие), зачем нужен poisoning, и в каких случаях parking_lot всё ещё имеет смысл тащить в зависимости. Заодно вернёмся к моей старой async-статье и поясним конкретнее, почему в async-задачах std::sync::Mutex это проблема, и при чём тут вообще futex.

Short-term #synaptic #plasticity (#STP) transiently modulates synaptic strength based on recent activity. #ShortTermDepression #STD reduces efficacy during repeated activity, while #ShortTermFacilitation #STF can enhance responses to closely spaced #spikes. These dynamics shape #NeuralProcessing, #filtering, and synaptic #homeostasis. Here's a short #Python implementation and simulation in #NESTSimulator:

Распознаем STL-код легко: std::vector
Нередко в процессе реверс-инжиниринга мы сталкиваемся с STL-кодом, анализ которого на первый взгляд кажется затруднительным. Неопытный глаз может принять этот код за полезный и потратить время на анализ какого-нибудь конструктора. На самом деле, здесь важно потратить время на то, чтобы распознать STL-контейнер по косвенным признакам, быстро понять, где какие данные лежат, типизировать их и идти дальше. В новой серии публикаций мы расскажем о самых распространенных контейнерах STL и начнем с std::vector . тык

As Trump's approval ratings have fallen precipitously, from "only hardcore MAGA idiots like him" to "slightly less popular than a politician with multiple communicable diseases", his inner circle and lickspittles in the House and the Senate are all desperately pointing fingers and playing the blame game, trying to ensure that someone, anyone else is blamed for Dear Leader's disastrous administration.
I'm reminded of the saying, which I think was born out of the French revolution and the terrors that followed:
"Every revolution eats its children."
I think in this case, Stephen Miller may be taking this a bit too literally. It's just past noon in Washington, D.C. Do you know where your children are?

Mit ihrer feinen Nase prüft das hungrige Kätzchen, ob es da oben auf dem Tisch etwas zu fressen gibt.
Wann prüft das Bundesverfassungsgericht endlich die Parteien, die vom Verfassungsschutz als rechtsextremer Verdachtsfall oder gesichert rechtsextrem eingestuft werden?
Lass uns jeden zweiten Samstag im Monat dafür werben, dass der Bundesrat von unseren Landesregierungen dazu aufgefordert wird!
Nächstes Mal 14. 02.26

C++ #std::move doesn't actually move anything! 😱 Dive into 42 minutes of existential crisis with a deep dive into value categories, where #optimization ironically slows things down. Because who doesn't love reading about convoluted code that does absolutely nothing? 🧐💻
