I get the feeling that all of these assembly jokes are justifications to avoid learning assembly.
You can still make syscalls in assembly. Assembly isnt magic. It isn't starting from the creation of matter and energy, it's just very specific code.
Assembly code is for writing C compilers, and C compilers are for writing Lisp interpreters.
I saw a Scheme interpreter written in assembly running a C compiler written in Scheme.
There’s actually good reasons for this design. It’s easy to write a Scheme interpreter in assembly, but it’s hard to write a C compiler in assembly that handles everything correctly. Much rather write it in higher level language if possible and Scheme lowers the bar to getting there, so you can get away from using assembly as quickly as possible. Or you can copy somebody else’s Scheme implementation of a C compiler because now you’re platform independent.
Then you can write your C compiler in C (or steal a better compiler already written in C) and close the loop. For your final step, you use the C compiler to compile itself.
Only the most very basic compilers. C compilers are in C mainly.
Not the first C compiler obviously. According to this Stack Overflow post, BCPL* begat B, which begat C. Language self-hosting is pretty fascinating.
*Perhaps BCPL was originally written in assembly; I’m not certain: https://github.com/SergeGris/BCPL-compiler
Look at mister fancy pants with and assembler.
How about entering straight opcode, operand with only a hex keypad and two pairs of 7 segment LEDs. You can only see one set of numbers at a time. You had to write it out on paper to be able to keep track and count positions so you don't use your spot.
I had to do this as a project in school. Two 8088 units that we breadboarded to a UART that we used to drive a fiber optic link to communicate with each other with a basic protocol. All descrete components hand wired and coded.
It made you tie all of skills together into a full system of hardware and software.
Alright you and Joe McMillan had a great weekend we get it
Assembly used to be a required course for CS undergrads in the 90s. Is that no longer the case?
Also we had to take something called Computer Architecture, which was like an EE class designing circuits with gates and shit.
Which target did you use? Having to learn even a fraction of modern x86 would be ridiculous, but SPARC or something could be good to know, just to reduce the "magic box" effect.
I learned MIPS as an undergrad. Pretty neat little RISC architecture.
This was a long time ago. I’m pretty sure it was 8086.
Its still a thing
Required course work for electrical engineers in the early 2000s.
I had to learn assembly but was one topic of many we handled in architecture. Like one question of one exam. That was one of the toughest professors we had, class was about 2001
IMHO assembly isn’t hard. When you gain enough experience you start to see „visual patterns“ in your code. For example jumping over some lines often equals to a if/else statement or jumping back is often a loop etc. Then you are able to skim code without the necessity to read each line.
The most difficult part is to keep track of the big picture because it is so verbose. Otherwise it’s a handful or two of instructions you use 90+% of the time.
I needed it often in the past in the PLC world but it is dying out slowly. Nonetheless, when I encounter 30+ year old software I’m happy to be able to get along. And your experience transitions to other architectures like changing from one higher language to another.
Nonetheless, if I’m able to choose, I’ll take Go. Please and thank you 😊

It's a long time since I wrote any assembly in anger, but I don't remember this being an issue. Back then Id be writing 2D and 3D graphics demos. Reasonably complex things, but the challenge was always getting it fast enought to keep the frame rate up, not code structure.
As you say, I think you just establish patterns to decompose the problem.
Anyone who thinks OP asking about Assembly with this meme should play the game Turing Complete. It's great. You have to design a computer all the way from the most basic logic gates (I think you only get a NAND gate to start), designing an ALU and CPU, creating your own machine language, and writing your own programs in the language you designed, and it's all simulated the whole time. Machine language is pretty advanced as far as things go.
From your description this sounds more like a job in IBM’s R&D department than a game
All the best games sound like jobs when you describe them.
factorio, satisfactory, oxygen not included, RimWorld, Stellaris, dwarf fortress, gregtech new horizons...
We got to do something simular in uni. We modeled the CPU in VHDL and had to set up our own language, then we were to program a game for it. One of the most fun and interesting courses we got to do!
It's now been 18 years since the last time an employer paid me to write assembly, but it's only been a year or so since the last time I had to read assembly at work (in order to verify what the compiler really was doing).
OS and embedded dev here. I use assembly all the time. I've even worked on firmware that was entirely in assembly of strict requirements that couldn't be met in C.
Also even machine code hides a lot about how the underlying machine works so if you really want to do computing from scratch you really do hate to invent the universe because there's abstractions all the way up the hardware stack just like there is in software.
Not exactly accurate, I think. Even machine language is bound by the CPU's architecture. You can't do anything in machine language that wasn't specifically provided for by the CPU architects.
It would be more accurate to say it's like creating a new universe using all the same laws of physics, thermodynamics, cosmology, ethics, etc as our existing universe.
I don't think accuracy was the goal, it is a joke not a dissertation. It's more about how it feels to try a language like assembly after working with higher-level languages.
Ha! I teach assembly and use this one every year to lighten the mood before midterms.
I remember watching assembly demos in the early-mid 90s and thinking those guys were wizards
Syscalls are sitting right there, and you can always just link libc...
I had an assembly class in college. I didn't love of at all. Got my first job after graduating and it was writing space shuttle engine control software, which was in assembly. I was kind of surprised at how fast it became natural after dealing with it full time. Still, it felt luxurious when we upgraded the controller and could do the software in C.
"oh no, I had to do literal rocket science"
In college back in 1991. Also had to do PASCAL and FORTRAN but thankfully those two were in a single course.
I also took PASCAL in the 90s, but it is considered a high level language, and writes similarly to other high lvl languages, assembly has a very different syntax
Not since the 1980s on a Commodore 64.

I learned assembly for a few weeks when I first started a new job once (didn't even have anything to do with my job), and I always felt like my brain was tired after trying to write in assembly. Just took so much more mental concentration than writing in c for example.
Only on the VIC20 and Atari STe. On the VIC20 you had to write the assembler, manually convert it to machine code and enter that into the computer. There was a cartridge with an assembler, debugger and an extra 3.5Kb memory for it but I never got one.
I was pretty into x86 asm in my teens. Nasm was my go to. Anyone else ever play with MenuetOS?
Nah, I don't hate myself that much.
