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).
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
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.
For a university assignment, I built a compiler for x86; I cheated a bit by relying on LLVM, but it gave me a better understanding of the architecture. I also developed emulators for the NES (Ricoh 2A03) and RISC-V (RV32I) as a hobby. For the latter, I implemented it in FPGA.
I used to write z80 asm without an assembler back when I was a LOT younger. The ZX spectrum manual I had, had the full instruction list with the byte values.
I think it was oddly easier than some higher level languages for some tasks.
But, making changes was an utter nightmare.
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.
It’s just a joke friend.
A very bad one if it requires switching off a large portion of your brain to find it funny.
suspension of disbelief
I said so in my comment, try to keep up.
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.
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!
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…
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.
Assembly code is for writing C compilers, and C compilers are for writing Lisp interpreters.
Only the most very basic compilers. C compilers are in C mainly.
And that’s how you get the Thompson hack
Talking about bootstrap here?
Indeed
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
Back in High School in the 80’s me and a buddy wrote a Z-80 editor assembler in TRS-DOS BASIC.
It was not rocket science.
I never did get very far with the TRS-80 Editor Assembler, but that was my first exposure to such things.
I also remember the BASIC code for the Dancing Daemon which was replete with PEEKs and POKEs, such that much of it was written in machine code.
Exactly how we did it too. We created the editor/assembler that peeked to see what was there and display it in Assembly, Hexadecimal, and ASCII.
You could edit whichever version you wanted and it would Poke it into RAM.
You could also save swaths to a file.
True, it was computer science.
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, but it’s hard to write a C compiler that handles everything correctly. Much rather write it in higher level language if possible and Scheme lowers the bar to getting there.
Then you can write your C compiler in C and close the loop. For your final step, you use the C compiler to compile itself.
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.
Vic 20 was my first. I watched my dad struggle with and eventually give up on assembly. Something-something and the microbots. I was fearful of it until I took Assembly at Uni. That 2nd/3rd year class was where the final puzzle piece of how computers work fell in place for me.
My first job was writing assembly tests for a DSP hardware design team. Fell in love. Never looked back.
Assembly was easier to me than C/C++.
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
Oh, I know. I meant that we had to take courses on older languages as part of the curriculum. That was a funky little college program. The oddest experience for me was taking Python back in the day as the “new thing” then not seeing it again until it absolutely exploded ~10 years ago. That program is also why I ended up playing with Linux so early on. The professors truly seemed to have a passion for emerging technologies while not wanting anyone to forget what came before. Thankfully, no punch cards.
We used turbo pascal in school in the early 90’s. And it had assembly blocks… which I used copious amounts of because it was the only way to make the IBM PS/1’s do useful graphics.
Ha! I teach assembly and use this one every year to lighten the mood before midterms.
Not since the 1980s on a Commodore 64.
