I’m high and I can’t make sense of programming software

[BaldingSoHard]

Where did machine language come from?

Machine language is built into the cpu hardware. You can feed it a sequential string of 1's and 0's (or hexidecimal depending on the cpu) and it will parse and execute, assuming your input string isn't garbage.

You type code into a program to let you create another program. But what code was used to create original program?

I literally can’t process this right now. Certs nikkas explain this

Computers use and understand binary code (assembly/machine language) which is basically just numbers. 1s and 0s. Think the numbers you saw on the Matrix movie. Extremely boring shyt. Programmers would blow their heads off if they had to write code that way. It’s called low level language because you’re getting closer to the actual hardware of the computer. Programming languages are called high level language because it’s closer to actual language that humans can understand. So it makes programming easier. When you code, behind the scenes, there are mechanisms (compilers) that transform your high level programming code into the binary code that the computer understands.

Or something like that I was an Econ major in school, not a Computer Science kid.

Anyone ever take that Nand to Tetris course?

We should have a thread that just teaches brehs this stuff in layman's terms

Binary code is where it came from.

Pretty sure binary code was invented in the early 20th century around or right after the world war.

This is the beautiful shyt you type in

What the computer sees

I had a similar thought earlier in the week

Like brehs are explaining it but I'm still here thinking, how did a guy even come up with the idea of coding and programming?

 

[I Really Mean It]

CPUs are made up of components called registers. CPUs have instruction sets that define a bunch of boolean logic behaviors that the CPU will execute. Register values are series 0s and 1s, off and on respectively, and loading certain registers with certain values yields different results. This whole concept forms the basics of programs - they're just sequences of instructions to be executed by the processor. Compilers are just programs that translate higher level languages into byte code and machine code. The machine code is literally represented in 0s and 1s. If you cared enough, you could write a program entirely in machine code, but it wouldn't be worth the trouble. The closest to that you'll see is assembler (ARM, MIPS, etc) that is more human readable but extremely low level in that you define each operation yourself. In a higher level language like Java, C, Python, that's all abstracted away from you.

I had this thought at least 10 years ago. It had to start somewhere. I also can't wrap my head around it.

Just tried to explain to my girl because we were watching Zero Days

Should have just let her carry on posting on Instagram

 

[dj-method-x]

It all boils down to 1’s and 0’s

 

[Mr Hate Coffee]

I forgot about this thread. Logged into the Coli today and saw my alerts. Read them shyts like


Thanks for the brehs that helped. I actually learned something.

I agree but.

Register values are analogue not digital.
Some compilers do that, others do other things. Typically native compilation results in assembly code rather than machine-code per-se. I.e. predefined instruction set operations. Although assembly code is a sub-set of machine code.
The instruction set is a bunch of predefined operations.
Between assembler/machine code and the hardware you have Microcode - Wikipedia .
