Ask HN: What's the best resource for learning modern x64 assembly?

As others points out NAND to Tetris is a really good entry point to learn assembly. It begins with you designing the hardware from NAND gates. You will make all hardware components like memory, instruction decoder, ALU, and CPU, and put them together into a computer. The next step is to build a virtual machine and then a compiler for a high-level language called Jack. The keystone project is to build a game in Jack and have it run on the computer that you build :)

I have since then ventured into Motorola 68000 assembly coding, by reading an old Amiga course in machine code from the late 80'ties. It's fascinating to learn from an old platform like the Amiga 500.

To keep myself motivated, I have written a lot of posts that chronicles my progress through the course.

EDIT: I can also recommend this game, that is inspired by NAND to Tetris. Where you build the hardware in your browser :) http://www.nandgame.com/

Start with this one: "Reverse Engineering for Beginners" https://torus.company/writings/RE4B-EN.pdf

Little warning, Microcorruption may be no longer monitored at this time. Account registration is not automated.

A hacker I closely follow tried to play Microcorruption during a Twitch broadcast, and, to my great disappointment, he was unable to due to lack of response.

I'm learning Z80 for programming the rc2014 kit (it's really nice kit if your also into electronics). There is a surprising lack of information online about the techniques of programming. For me that's the biggest struggle. You can know the instructions but juggling registers in an optimal way is hard. I'm currently learning I can use the stack inside a routine to have more values in the air at the same time, but then I read some example code and learn a particular instruction can be used in a clever way to avoid all my stack juggling. I am finding it can take hours to write a simple routine. I really get it now when people write it's a non-trivial problem to map C to assembly (especially Z80). Hell, it's fun though! Screw all these high level languages, let's do everything in assembly and damn the horses!!

this is hands-down among best that are out there (and it's free). It is known under 2 names[1] which might be a bit confusing but it _IS_ about assembly.

see this HN thread (450+ points) discussing the book at the time: https://news.ycombinator.com/item?id=21640669 It is also constantly updated.

This books is to ASSEMBLY what Richard W. Stevens is to TCP/IP and UNIX programming. Also it IS a beginners books because he makes no assumptions about the readers previous experience. It is very thorough so it's probably the only book you'll ever need on Assembly :)

[1] explanation from the author:

> What is with two titles? The book was named “Reverse Engineering for Beginners” in 2014-2018, but I always suspected this makes readership too narrow. Infosec people know about “reverse engineering”, but I’ve rarely hear the “assembler” word from them. Likewise, the “reverse engineering” term is somewhat cryptic to a general audience of programmers, but they know about “assembler”. In July 2018, as an experiment, I’ve changed the title to “Assembly Language for Beginners” and posted the link to Hacker News website, and the book was received generally well. So let it be, the book now has two titles. However, I’ve changed the second title to “Understanding Assembly Language”, because someone had already written “Assembly Language for Beginners” book. Also, people say “for Beginners” sounds a bit sarcastic for a book of ~1000 pages.The two books differ only by title, filename (UAL-XX.pdf versus RE4B-XX.pdf), URL and a couple of the first pages
