/prog/ - Programming★

CMU's 15-213 class covers it

http://www.cs.cmu.edu/afs/cs/academic/class/15213-f16/www/schedule.html (click on video, they work)

If they stop working find the 2017 version, they're on youtube.

Get the book too, CS:App. Once you're finished, google microcorruption and try it.

That's all you'll ever need. Now, write code!

The best books I have read about it:

Bartlett -- Programming from the Ground Up

Zhirkov -- Low-Level Programming

I've only programmed in it in as much as you need to understand it for buffer overflows and the like.

Oh and the Zhirkov book is mainly (completely?) x86_64, there are quite a few differences. And '64 has two different calling conventions: one for Linux and one for Windows. They differ in which registers are saved to/retrieved from the stack on function calls.

Ugh what a sad reminder of my unanswered stack overflow thread about an x86 problem I'm having. I opened it an hour ago (https://stackoverflow.com/questions/53967161/segfault-when-writing-into-data-segment-even-though-sufficient-space-allocated) or so and not one answer.

Are there any resources for i960 ASM? A huge stretch I know, but I can find almost nothing. The only online resource is some college project which used CTOOLS 5.0 code to create some sort of network.

Well, if you must.. just Wiki the i960, the last external reference listed deals with instruction set.. and then get good at assembly.

https://software.intel.com/en-us/articles/intel-sdm

https://developer.amd.com/resources/developer-guides-manuals/ (scroll down to the "AMD64 Architecture" heading)

These are the official reference documentation for the x86 architecture.

what are some comfy systems to learn assembly for if you want to start from nothing like Terry and build something akin to an os? like easy basic graphics/hardware interfaces in assembly. i guess i could go for a ti-84 but i want something more featured, preferably better than a c64 but that's probably getting into graphics accelerators and i have no idea what i'm doing.

again i have no idea what i'm doing or what i want since i'd also want a system with a good emulator so i dont have to pay an arm and a leg. i guess i'm stuck with a ti-84 in reality. the c64 emulators i tried wouldnt even run BASIC commands so i dont think that's the way to go. just jumping into x86 or A64 (i have a rpi) seems like trying to learn to swim by diving in lava.

should i just focus on C and not give a shit about assembly?

MIPS is popular for learning, it's relatively simple but had actual hardware.

thanks, i'll take a look

Learn RISC-V.

MIT's entire 6.004 class is open sourced, including the lectures which are all on YouTube https://6004.mit.edu/web/spring19/resources/lectures

You can buy these chips for next to nothing, and program them from the ground up yourself. A hardware hacker's dream. India and some other countries are working on a total replacement for ARM using RISC-V. Learn it now and get in on that action if it ever happens.
