#x86 — Public Fediverse posts

ASM-editor is a modern web application for writing, executing and learning M68K assembler code (and MIPS, RISC-V, X86), which uses the SvelteKit framework and the Rust programming language.

Since our last news item, among other things, an introductory course on general assembly languages and an AI assistant in each editor that takes control of the editor and the emulator have been added.

That means that all your distributions need to be patched. For me it meant that I need to do to go to all machines both physical and virtual and Patch them.

It is a lot of work that has to be done!

@Dendrobatus_Azureus

Do not forget to always patch your Linux / BSD distributions wherever they may reside.
Forgetting to do so may open up your systems for known exploits which is easily avoidable, from the InfoSec perspective

In case you don't know termux yet on ARM architecture go read and learn

🎩✨ Oh joy, yet another riveting exploration of integer overflow checks – because who wouldn't want to dive into the thrilling world of compiler flags and conditional branches? 🤔🔍 Surely, decoding a branch on #x86 is everyone's idea of a fun-filled weekend! 😂🚀

[Status Update] - The breakdown on the death of x86 is live. ☠️

Yesterday I mentioned I was compiling a deep dive on the x86 architecture and its physical bottlenecks. The deploy is done and it's holding up.

I went straight to the point: no fluff, just pure register spilling analyzed line-by-line on Godbolt to show exactly why a 50-year-old design is suffocating the industry. If you want to see the hardware gasp for air on a trivial loop, here's the dump.

I bookmarked this 1983 book on Intel 8086/8080 Assembly programming with a focus on the IBM PC hardware. It seems a good resource, especially on the architecture of the processor, but has fewer code snippets and examples than similar books.

Как одна буква в ассемблере стоит 3× производительности

Я хочу показать вам, как одна буква в ассемблере может стоить 3× производительности. Не в теории — на живых замерах. По дороге мы заглянем внутрь процессора: Register Alias Table, partial register merge, scheduler, latency vs throughput, и даже обнаружим, что делитель выдаёт остаток раньше частного. Но начнём с основ. Приготовьтесь: кроличья нора окажется глубже, чем кажется.

[Перевод] Как работает движок микрокода процессора 8086

Микрокод часто описывают как аккуратный промежуточный слой между инструкциями и «железом», но при попытке посмотреть на него на уровне кристалла эта картина быстро усложняется. В случае Intel 8086 это особенно заметно: за компактным набором микроинструкций скрывается набор инженерных компромиссов, распределённая логика декодирования и нетривиальная схема адресации. В статье разберемся, как устроен сам движок микрокода 8086 — от выбора точки входа и исполнения до организации ПЗУ и вспомогательных блоков, которые позволяют уместить всё это в ограничения конца 70-х. Внутри процессора

I agree but on one point: computers are as good as their hardware and software combined (the old saying about the weakest chain link comes to mind). So we should really think about working on replacing the hardware, before we are irremediably locked out of running what software we want.
