Here is a meme that was shared by a group of disassembler enthusiasts.
@nixCraft how can I learn assembly? Is this still relevant today for reverse engineering?

@Feynman @nixCraft I learned it by writing stuff and disassembling it, then trying to understand what it's doing. And yes, absolutely still relevant, even though a lot of enterprise software is Java, almost all of it has a bit of compiled code and that's usually where bugs live

If you check out the various work I did on https://skullsecurity.org/cv you'll see a ton of reversing

@nixCraft I’ll learn assembly on ARM on Raspberry Pi Pico. Remembered I had a course in college on MIPS (that I never went to) in CS.
@nixCraft Server-side code still isn't though :3

@nixCraft In a similar way, minified JavaScript can be considered to be open source…

Understanding and modifying it seems to be too much of a chore for me to even try. (Applies to both.)

@nixCraft assembly is not machine language. Assembly still needs to be compiled/interpreted.

@nixCraft

But it still not free/libre :(

@nixCraft I had it in college and it was hands-down the best and most effective way to really screw something up…until I leaned C which allowed me to screw lots of things up at the same time.
It’ll teach you how a computer works though.
@nixCraft I feel the wording needs "eve-e-e-entually" somewhere in there. 

@nixCraft *source available

(Sorry 🤣)

@nixCraft hate to ruin the fun, but:

- That's not open-source. Don't believe me? Read the definition for yourself: https://opensource.org/osd/

- It's not actually the real source code.

- A lot of EULAs actually don't allow reverse-engineering, so to do it legally you would have to fall under one of the situations where the law would override that (iirc security research is one of them)

The Open Source Definition

Introduction Open source doesn’t just mean access to the source code. The distribution terms of open-source software must comply with the following criteria: 1. Free Redistribution The licens…
