I had a couple assembly programming classes during my CS course in university. It's definitely a much different way of writing programs compared to higher level languages. To me, it felt like a puzzle game, where management of "position" within memory was a huge part of it. Function calls are also interesting, since essentially it's just a block of code in memory with a pointer you can jump to, then jump back to your previous position once finished. Even a program to just do simple math was quite involved. No such thing as strings either, just char arrays.
Funny enough, taking that class on assembly finally helped me "get" C. All the stuff about pointers and memory management/allocation didn't click until writing assembly, then I understood what it was for. Looking at C as an abstraction over assembly really helped me become a better programmer.
This gave me an idea for an actual puzzle game where you use simple opcodes to move numbers between boxes and it gets more and more complicated until you realise that you’re writing assembly
That's EXACTLY what C was designed for, my friend. Congrats
Yep, C is basically a better macro assembler. I feel your heureka moment!
I came from the other direction, and it took a while to get what C was actually good for :)

"My favourite part about WebAssembly is that neither has it anything to do with assembly, neither has it necessarily to do with the web."
Wasm is a regression to software development. i dont understand the hype at all
@@archmad Its hyped because it allows you to write web applications with all (or the majority of) Javascript abstracted away. I would never go back after using blazor wasm. Its just miles easier to write good code and you get access to powerful tools like resharper / nuget ecosystem ontop of anything javascript.
@@archmad Wasm is Java done right with the experience of 2 decades of failing. Change my mind 😛
@@ZephrymWOW as much as i love wasm for what it allows, i must say my experience with it supposedly eradicating the need for js has proved that it isn't really finished.
WebAssembly seems to focus too much on being 'headless', being able to be run without the web browser nor even js enviorement, completely ignoring that this is the whole point of why it was created in the first place.
Every single possible action you'd want to perform in javascript can indeed be performed using wasm, but only after you:
1. Import the functions needed.
2. If they have anything to do with strings, go through thousands of loopholes to get them right for both the wasm memory and js memory.
3. Only then call said functions within your wasm.
It results in that either you or your enviorement/build tools (emscripten, wasm-pack, etc) *will* end up generating a *huge* mess of a "glue" javascript file that does the thing your web browser should have done in the first place.
This is completely unnecessary and shouldn't be a problem in the first place, yet it is.
Thus every website implementing webassembly will come with these giant files that will sacrifice the page loading times, cache space and overall both user and programmer experience.
One step forwards, two steps backwards.
I love yet i hate it. It's awesome.
@@beProsto 1.) You are misusing dependency injection. You can enable everything globally and it will be injected as needed. It's a better version of web pack. 2.) Give me a real example of your talking out of your ass parroting someone else. 3.) Its headless because of MAUI. You can just use a blazor dll and now you have xplatform THAT RUNS ON KERNEL. Every other alternative spins up a chromium container and is a glorified browser.
Always wanted to learn Assembly, but never have I understood it's complexity. You simply explained the most basic part of the Assembly language in 100 seconds clearly. Thanks! I might use this for future references!
Hey! It helps to start learning assembly on older chips that were less complicated. In my Uni we work with assembly on 8051 microcontrollers. They are quite old, but it's easier to grasp the basics on them. Overall, architectures used in microcontrollers tend to be a bit easier to understand than x86.
You should go ahead and learn it. I personally feel that my ability to debug things and make programs work increased after working on some simple projects in which I coded in assembly language.
I would say that instead of learning about x86 assembly language, you should learn asm of Arduino Uno/Atmega328p. That is where I started. It is simple, and when those LEDs blinks, you get a feel of what it means to write assembly and how stuff works.
I'd highly recommend starting with a RISC instruction set like ARM. It's a reduced instruction set so it will be a lot less confusing than x86 when you are just starting out. Derek Banas has a pretty good video to get you started: ruclips.net/video/ViNnfoE56V8/видео.html
Learning an assembly language is pretty useful to better understand how a computer operates, I would also recommend going for a RISC architecture, they tend to have less instructions and more registers and I feel that helps reducing the complexity to start doing something nice, even if it is just adding 2 numbers and saving the result in a third registry. The one I first started with, many years ago, was the MIPS 3000 variant, that was the cpu used in the PlayStation 1 and very similar to the one used in the Nintendo 64.
Assembly is simple, it consist of simple instructions. The complexity comes from trying to program more than adding two numbers together. You need alot of instructions, to construct higher level logic, take care of program state, access memory, data structures. Then you need to understand many registers in the processor, how talk with all the peripherals and so on. It's easier to start with microcontroller and move from there. I enjoyed the AVR architecture, it's 8-bit CPU with about 100 instructions. But the whole processor datasheet can have 500 pages for all the various modules like analog to digital converter or serial interface.
Assembly only looks complicated to the beginners but it's really not. MASM even provides high level directives like IF, ELSE, WHILE and standard macros for I/O that makes it really straight forward to focus on the performance of your algorithm.
I never knew this, that's pretty cool.
What's the difference to C at that point?
@@eUnkn0wn you can write inline assembly in C if you want, difference is of performance and control over your code, bit shifting and direct access to stack frame and hardware. You can't do that with C
I had a tutor back in the mid-90s when I was just a teen hanging out on the local BBS... he always said "it's all rather simple", and I never got it and was wholly confused.
Until one day when it just clicked and I realized all you're doing is reading, changing, and writing values to memory or output ports, and whatever is there interprets it; like the value 10 can be a green pixel in video memory.
@@raz0229 There is a talk by Matt Godbolt "What has my compiler done for me lately" (or somesuch), where he demonstrates really well how unlikely you are to optimize better than your compiler at this point. Besides C is basically just that: High-level assembler.
Not saying that dabbling in ASM doesn't have its place, but personally I needed it mostly for debugging.
0:46 WebAssembly should not be confused with normal Assembly dialects like x86. It is much more of a compilation target than a language you would actually want to write in for performance reasons.
exactly, apples to oranges comparison, almost nothing related between those 2 other than having "assembly" on the name
I would say that the WebAssembly text representation totally qualifies as an assembly language for the WebAssembly binary representation.
Also, you can also theoretically create actually hardware that runs WebAssembly binaries, it's just that it's intended use case is to run it on a VM, similar to Java.
Wasm is a binary instruction format rather than assembly. However it does come with an assembly like language. I don’t know it’s name unfortunately
@@sohn7767 afaict it's just known as webassembly text format. Its file extension is usually .wat

Also, store the assembly code at sector 0 of a floppy, and you got yourself a booting program 😄
A quick correction: the bss section is for variables whose size is known but data is not. We reserve space for variables in the bss section with resb (reserve byte). The data section is for variables whose initial value is known, and the rodata (read only data) section is for constants
A small but important caveat: in most use cases, assembly still sits above the OS / kernel. So you won't work with actual physical memory ("bare metal") but with virtual memory; an abstraction provided by the OS. An exception might be when you are programming in kernel space.
Man. Your videos are so clean. So precise. No junk. No dumb intro that lasts 10 seconds. You title it perfectly as well. Thank you for adding junk-free material to the internet.

@@treanglewho was he?
also, .data is not for constants that do not change, it's basically an initialised version of the .bss section that takes up space in the executable. you can actually change it. for actual constants that do not change, use .rodata.
Interesting video though :)
That makes sense, given that I gotta assume rodata stands for read-only data
@@finadoggie yep
that takes up space *in the executable*. .bss, .data and .rodata all take up space in memory, the difference is that .bss is not stored in the executable but initialized with all zero bits by the executable file loader.

Every programmer should learn the basics of NASM/FASM. It teaches you so much about architecture!
This is propably the best video about assembly which I have ever seen (so far).
This is the most condensed one yet! Glosses over TONS!
Note: The method you used to write your hello world program here wasn't really "just" assembly (which is understandable, since writing a miniature operating system for a '100 Seconds of'-video is probably out of scope). You still used the kernel-specific API calls.
TBF if you run something in a modern operating system you HAVE to use API calls (called system calls) for anything that isn't just calculations. Otherwise you'd segfault.
So unless you want to install DOS or create your own ring 0 OS because you want to build the third temple on your computer or something. You gotta accept that nothing you write will truly be "in assembly".
@@mrmimeisfunny At my job we don't use a operating system (well, we make our own RTOS), instead we program an SPI link to a PuTTY-linked peripheral and printf by sending data down the SPI line. So you can do printf without any API/syscalls, but bugger me is it hard work
@@mrmimeisfunny I should have clarified that I know that there's really no other way to do this (without writing your own os). Would not exactly be great if any program could just run any instructions it wants to without restrictions (through syscalls/an API).

Repent and follow Jesus my friend! Repenting doesn't mean confessing your sins to others, but to stop doing them altogether.

I have been looking at Gameboy assembly for a long time, mainly for the GameBoy and GameBoy Color. Starting with the GBA, you can use ARM instruction sets and the tooling for both is pretty incredible (sdcc, lcc, z80sdk, ...). It sure is far different from writing nice looking code, but if you want to get something critical done, then your best way of achieving it, is to skip every and all abstractions and go bare metal via Assembly. :)
Actually DevKitArm and GBDK is the way most people go nowadays and some people actually managed to make impressive stuff with it thanks to the layer of abstraction. We're seeing more and more people make games for those platforms and part of the reason is excellent support for the C programming language. Now, if only CC65 was actually just as nice...
@@doigt6590 GBDK uses SDCC and I personally am still waiting for it to actually support C99... I wanted to try and use V which compiles to C, but because of ampersand statements, it makes SDCC error out a lot. But, DevkitARM/-PPC is amazing! I have those installed too. Personally, I am impressed how many unofficial SDL ports there are for some of those handhelds, which is pretty amazing!

I got my start with MIPS32 in university and I'm currently learning 6502 assembly just for fun. It's a really fun CPU to learn and the X16 uses it just like the C64.
I learned MIPS in university as well, does it matter what version of assembly we learn? When starting out I was so confused on the difference between arms and mips, and when searching tutorials they never showed what I was learning in class. I want to learn assembly but don't know what version to go with.
@@sergiohernandez72 That depends on why you want to learn it. If you want to understand the concepts, it doesn't matter. Learn any or preferably several of them (to see the differences). You might even want to have a look at completely synthetic ones (like MIX or DLX) or byte-codes like Pascal's or Java's. If you want to write real-world code in assembly (to make if faster or smaller or remove side-channels) then you would learn the assembly language of a processor in wide use: x86_64, ARM, some microcontroller, maybe a GPU ...

Former communication engineer with what was once the BBC World Service...
The sender control system at transmitter sites was written in Assembly which controlled banks of microcontrollers which in turn controlled the sender transmission schedule. Even in 2000 that was an arcane system of control.
That said it was reliable. The software manual which contained all the instructions for the control system was as dense as a doorstep.
The programmer who designed the code could be found lay belly down on the floor of the sender control system rapidly flipping through the hundreds of pages of instructions from the system manual to try to find bugs. They knew their code structure inside out and back the front.
An amazing feat given that there was no IDE or such like at the time of it's original development (80's) - simply amazing human memory and knowing instantly every line of code and where it sat in the overall program.
We don't know we're born these days.

Update: I've managed to code an entire biginteger library in x86 assembly. Truly has been a ride.
Great buddy!
I grew up with the C64. You could relative simply write Basic programs, which was great but they were quite slow. Assembler (for the 6502) was difficult to learn (even more without the possiblity to get information via the internet, you needed books, books, books...) but gave you a lot more possibilities and exponentially more speed. Note that with assembly language you don't only have to learn the instructions (mnemonics) and how to build routines, but also how to use libraries or the system custom chip architecture with all of its registers and how they work. Using Assembler was a must for quality and speed. And so, on 8 bit systems like the C64 nearly all of the commercial software was written in this tedious but fast language.
Note that the detail information from 1:00 in the video is for x86 assembly, which runs on modern pc systems but is ... as a language a bit clunky.
If you want to try out assembly yourself I'd recommend 6502 asm f.e. for the C64, which is pure 8 bit oldschool. Or 68k assembly f.e. on the AtariST or Amiga. It's nearly orthogonal, which means it's a good/nice assembler dialect imho. Compared to 6502 asm this 16-bit assembly is a bit more powerful and convenient. Btw. Winuae is a good Amiga emulator and Asmone a good assembler to start with.
z80 asm is my favourite, i used to do small games on my ti-84 calc with this, and there's some insane programs made in assembly for this machine, while the basic is just about using the functions to draw math stuff and things like this, the processor is a 15mhz z80 (while the gameboy is a 4mhz one) and assembly programs can use all of the archive memory, aka about 480ko (with 24ko of ram)... there's programs like a doom "port", a gameboy emulator or games simulating 9-level grayscale (there's no native support for grayscale on this machine), all of them entirely made in asm

I like to use intel 80386/80387 32 bit CPU. Today on an Android tablet with a Dosbox emulator app. I put all instructions into batch file to create tiny executable with a little help from debug.
I disagree that 65xx Assembly was difficult to learn. The Programmer's Reference Guide from Commodore covered pretty much anything you would want or need to know... and at least there was no need to deal with segments and offsets, as with x86 Assembly. If you used an Assembler (like PAL)... the landscape was even easier.
@@TheUtuber999 To have some 16 bit offset register on x86 are easier to handle as two bytes in the zero page of the C64 for building an address. On C64 we have a lot of calculation with 16 bit values, but only 3 register with 8 bit.

After instruction, there are zero or more operands. (Not one or more operands). For instance, a NOP (no-op) instruction has no operands.
Just when I’m starting to learn assembly, Nice.

Now that you've done 100 seconds for most languages, could you possibly try a 5 min projects/1000 seconds series?
Repent and follow Jesus my friend! Repenting doesn't mean confessing your sins to others, but to stop doing them altogether. Belief in Messiah alone is not enough to get you into heaven, you must become a new creation and be born again by responding to the Holy Spirit. - Matthew 7:21-23, Revelation 3:15-16 cf. Hebrews 10:26-29. Pay close attention to your thoughts and how you respond to your inner monologue because it has a greater impact than you think. Call on the name of Jesus and pray for Him to intervene in your life, and do all that you can to follow His ways.
Modern assembly is very different from old assembly, which was basically just a frontend for machine language
This is exactly what I was thinking. Just to to print on a screen we needed 3 or 4 short coded lines... You had to code the mechanics of dividing numbers, etc...
Boy this video would helped so much 6 months ago. Very basic but easy to understand
Understanding how assembly works helped me get a better grasp at C and C++.
tbh learning to read x86 assembly is pretty easy but when it comes to actually using all those specialized instructions like "CVTTPS2PI" (god i hate SSE) its quite overwhelming
first language ive ever learned (even before english ;))
Never thought you would bring this, but I LOVE assembly language. Even liked this vid with my 4 yt channels haha^^

A hierarchical database in mainframe assembly was one of my school projects back in the day. Great job explaining!
I remember the times when 100 seconds was 1:40 instead of 2:40 😄
I know, I am getting frustrated
Right when I thought you ran out of ideas
my dad programs in assembly and when I took the assembly class in collage that was super helpful
My great aunt used to program 30 years ago, and said her favorite language was assembly by far.
I was on the hub
But this is more important
Ayo wtf man🤨
same
wait what

I am a long-time coder whose first commercial products were written in 100% assembly. One of the things in this video that raised my eyebrows is the explanation of what a CPU "register" is. Do modern developers / coders / software engineers (you young things below the age of, say, 30) not understand the basics of CPU structure/organization? Do schools/colleges/universities still teach this, or are we letting our future software developers into the world thinking that a CPU is a magic black box that "just works"?
please keep in mind that a significant portion of viewers who watch these video is self-taught programmer who just want to get things done and in the context of current development toolchain that make a thousand abstract layer between code and bare metal i can see why they need him to explain what a register even is
I studied physics.
It is much more useful to just think of things as stuff that just works. We only wanted our equations to be solved and show us pretty graphs.
The world is changing and if someone wants to know the lowest level stuff possible, that is great. This skillset is still needed.
However, things that people expect of newer technology, like video games for example, can't be written 100% in assembly within 3 lifetimes.
The world needs both kinds of people.
Dude i can understand your concern but, ypu know what there are books in schools and universities where they teach you about things like how data is stored in floppy drives, older computers, older ball mouse. and there exist people who complain that the computer world has become more updated/agile/evolving there ain't so much time to learn about all these useless stuff. so it's up to individual's preference if they want to know about these things in deep or not.
I graduated with a CS degree last year. We had a few subjects related to the CPU architecture (including ALU theory), binary logic and discrete math. And yes, it had very little correlation with the programming we were doing.
Level 4 (first year) at a UK university here. Can confirm we learned that CPUs do indeed have buses, caches, clocks, etc. in them. Can also confirm that we didn’t go into more detail than that and that the magical things inside of the magical box just work.
ive been waiting for this video. thnx
Brooooo, you're amazing!!
It's so funny how he calls it an app lmao
Hey, quick question: If I wanted to make my own programming language without using LLVM , does this mean I have to use Assembly language ? (Assembly 86 or Assembly 64) . You know, to create the compiler ?
Thank you very much.
You can write your compiler for your programming lanuage in any turing complete language, it doesn't matter. The first C compiler was of course written in assembly, but then with the parts of C that were already compilable, the compiler was rewritten in C eventually (this is called bootstrapping).
You’ll need to learn machine code (to compile your language to it), not an assembler
Yes. If you use LLVM, you are responsible for emitting LLVM IR which resembles a low level programming language. After producing that, you feed it to lc (LLVM's compiler backend) which performs many optimizations and finally outputs assembly for many different architectures.
If you don't use LLVM, you have to output architecture-specific assembly. It is a great learning opportunity.
You can also target another high-level language like C if you want.
you are a godsend. thankyou kind sir.
I had to write some code for uni in mips assembly and really it was doable and actually quite fun as you are really close to the hardware stuff
You have so many things wrong. You can modify thigs in the .data section, the .rodata section you can't however. Most importantly, sections are not predefined, they are part of the ELF standard. You have many more, such as .rodata and .bss. Also, most importantly, webasm != asm...
