‍Mettle 0.15.0 и 0.15.1

31 июля состоялись выпуски 0.15.0 и 0.15.1 Mettle — языка системного программирования со статической типизацией:


Нативная поддержка x86-64 (+ AVX2), AArch64, NVIDIA PTX, SPIR-V (OpenCL 2.0).


Собственный линкер Windows PE.


Собственный отладчик на уровне исходного кода:

Без внешних форматов.
Точки останова, пошаговая отладка, а также чтение и запись переменных в реальном времени через --debug-hooks.
Без gdb, PDB и DWARF.



Бэкенд CUDA.


Без LLVM, виртуальной машины и рантайма.


Выполнение на этапе компиляции: функции с атрибутом @test запускаются в интерпретаторе компилятора командой mettle test, без создания бинарного файла. Команда mettle trace интерпретирует одну функцию и выводит построчное отслеживание значений. Команда --pgo интерпретирует функцию main() на этапе сборки и передаёт измеренные частоты вызовов обратно в оптимизатор.


Проверка заимствований (borrow checker):

Returning the address of a stack localreturn &localfn() -> &T lifetime error
Leak (no owner on any path)var p = malloc(n); return 0(Rust frees via Drop)




Компилятор основан на библиотеке libmtlc:

Собственный промежуточный язык (IR).
Классические и GNN оптимизаторы кода.
Нативная генерация кода (x86-64 (+ AVX2), AArch64, NVIDIA PTX, SPIR-V (OpenCL 2.0)).
Нативная компоновка.

Проекты написаны кейптаунским программистом suidvandiewereld на языке C (стандарт C99) и распространяются по лицензии Apache-2.0.

📰 Desktop Linux apps on Android proved my phone's biggest bottleneck isn't what I thought

Running desktop Linux apps on an Android phone sounds like the sort of thing that should fall apart almost immediately. You are dealing with a small screen, awkward touch controls, and an operating system that was never designed to work like a desktop operating system. Yet after using Termux and running Debian through Linux Deploy, I found that the display was not the biggest problem.

📰 Linux Kernel Begins Phasing Out the crypto_rng Layer to Simplify Random Number Generation

by George WhittakerLinux kernel developers are moving forward with plans to remove the crypto_rng API layer, a long-standing component of the kernel's cryptographic subsystem. The proposed change is part of a broader effort to simplify the kernel's internal architecture by eliminating redundant code paths and encouraging developers to rely on the kernel's modern random number generation interfaces instead.

OpenAI’s rogue agent swarm built a secret message board before hacking Hugging Face

OpenAI says its autonomous AI agents secretly coordinated for weeks through the company’s internal Artifactory package manager, sharing exploits, credentials, and task assignments. The disclosure has prompted OpenAI to slow some research while it strengthens monitoring and incident response.

Microsoft Teams PowerShell 7.9: WAM authentication and administrator changes

Microsoft Teams PowerShell module 7.9.0 changes how interactive Windows sign-ins work by using Web Account Manager (WAM). WAM is the Windows sign-in component that brokers a user's authentication for an application. The release also adds commands and policy parameters for voicemail, channels, meetings, calling, events, and AI agents, while removing the Teams Shifts Connection commands. This article separates settings you can use now from parameters for features that Microsoft says are not fully released.

Представлен Denial, композитный сервер со встроенным движком Flutter

Проект Denial развивает открытый композитный сервер на базе протокола Wayland, примечательный встраиванием движка построения пользовательского интерфейса на базе фреймворка Flutter. В отличие от традиционных решений, в которых Flutter-приложения запускаются поверх оконного менеджера, встраивание Flutter в композитный сервер позволило напрямую задействовать его для отрисовки всех элементов пользовательского окружения, создания анимации и компоновки окон. Проект находится на стадии публичного альфа-тестирования. Код написан на языках Dart и Rust, и распространяется под лицензией GPLv3+. При разработке задействован AI-ассистент OpenAI Codex.
