Деконструкция GO: Низкоуровневые концепции. Atomics. Часть 2.1

Я самую малость обленился и как-то давно не делал новых разборов, поэтому следующим нашим этапом деконструкции будут низкоуровневые операции . Иногда здесь будет в отрыве от аллокаторов/планировщиков и прочего, но опять же, статьи для тех, кто знает и хочет разобраться поглубже, как тут всё устроено. Поэтому, в этой части начнем с самого простого – пакета atomic. Концепции вокруг атомарных операций на уровне CPU я рассматривал здесь , поэтому советую почитать. Там мы даже пишем свой атомарный AND. !Важно! Мы будем разбирать на примере src/internal/runtime/atomics , то есть внутреннего пакета, а не того, который представлен нам как пользователям(потому что в исходниках я не нашел реализации). Но по большей части операции одни и те же.

Wow so Bitwarden CLI got hacked for about 90 minutes yesterday, through a very novel method. This malicious actor has hatred for LLMs (same Queen or King).

So they were using a worm introduced by the novel method to target keys associated with LLMs and other valuable keys. Very scary and sophisticated.

The normal version of Bitwarden wasn't affected, and of course the malicious altered version was depreciated so it can't spread. Still fascinating in a horrifying way.

Тетрис в ядре Linux

Вероятно, вы знаете, что если запустить ядро Linux без корневой файловой системы или файла initramfs, то оно упадет с сообщением о панике ядра. Но возможна ли работа ядра Linux без этих, вроде бы обязательных компонентов? Ответ на вопрос - да, возможна, но использовать такие возможности в конечном продукте не стоит. При запуске ядра ему могут передаваться параметры через командную строку. Одним из параметров является rootwait , указывающий ядру на то, что нужно подождать появление корневой файловой системы. В этом случае ядро ожидает появление корневой системы, а не завершается выполнение ядра с ошибкой. Формально ничто не мешает написать модуль ядра, который взаимодействует с клавиатурой и дисплеем и временно выполняет функции пользовательского приложения, пока ядро ожидает корневую файловую систему. Пользовательским приложением может быть, например, игра Тетрис. Она из-за своей простоты в реализации и зрелищности добавляет наглядности в изучении темы и дает чувство завершенности. А мысль о том, что тетрис, работает в ядре, усиливает эффект.

Record Low Snow in the West Will Mean Less Water, More Fire, and Political Chaos

You never do understand #lowlevel concepts in #programming until you actually go and implement them in something like #c .

I am working on the MQTT Client still and am learning a lot about #allocators and #memory.

I've learned about those things, both from the infosec and from the computer engineering sides, but now that I am actually implementing this stuff and having to make decisions and research and reading-the-effing-manual I feel that I am building an actual intuitive understanding of this stuff.

I've basically intuited 95% of the way to slab allocators before learning the actual term, like, it is just the logical progression.

Of course not everything is like this, but it feels very cool.

Man, I love computers so much!

@theoasisbbs This might sound silly, but I'm really hopeful that #Commodore might eventually make a new #microcomputer platform focusing on being intentionally simple. Perhaps a novel 16-bit architecture implemented in FPGA (or maybe something "truer" like ASIC!), designed to be relatively simple to program in a #lowlevel language. Sounds like a dream to me.

project introduction: Arkas engine (https://github.com/mesyeti/ArkasEngine)

Arkas Engine is a 3D game engine aiming to be a spiritual successor to Build Engine (used to make Duke Nukem 3D, Blood, Shadow Warrior)

It uses OpenGL 1.1 which makes it compatible with my favourite 20 year old computer that runs Windows XP

After reading an reddit post in r/osdev about someone doing the hard work of researching and documenting the ATI Rage 128 GPU, I've initially "just" wanted to grab some cheap old hardware of ebay (or other places like that) to actually get a test-rig going for my osdevving project(s) I have lurking around.

But o well, now I myself fell into a rabbit hole of R400+ radeon GPU's x3 (because thats roughly the range I would like to be able to use sometime in the future).

The Problem? While AMD claims that they have "open" documentation, the truth is everything somehow expects you to know the previous generation, with some having physically no available documentation.

Like I've been reading the Linux kernel driver (drm/radeon) on the side to even get a grasp at what I need to search for, and even then I'm left with next to nothing... registers are specified at a certain location, just for the kernel driver to read from an entirely different location! And the best part? Even registers that are relevant to each other (thus should be in the same "block"), have entirely different values in the driver source, with no obvious reason why!

I certainly will write an whole blogpost (or more lol) about this, but it's staggering what amount of stuff you need to grind trough to even get something simple as "resetting the entire card" (which is one write to a control register!).
