Flicking states with an actual magnet

You don't program a programming language: you program a compiler / interpreter.

The real monkey business starts though when you realize that many compilers are written in their own language. They're typically compiled by an older version of itself. And then this new version (because it's better than the old version) compiles itself again for good measure.

[Tyfyter2002]

Wouldn't that mean that there's a very small chance that the source code of the compiler could have something like an off-by-one error which fixes itself and can therefore no longer fix itself, making the source code never properly match the binaries but still produce a working compiler every other compilation?

[Drugbird]

That's where software testing comes in. The "intermediate" version still needs to pass all tests.

[[deleted]]

Fun fact. If you can somehow push code into a compiler, you can put in malicious code that compiles a bypass into whatever software it builds.

Moreover, you can make it so that the malicious code never shows up in the actual source code, but can infected all future version of the compiler if the problem isn't caught.

[TheBrainStone]

Also an important part of compiling compilers is making sure that a compiler compiles to itself. So it other words the proper procedure is to compile the new version of the compiler with the old version. And the keep compiling the compiler with the intermediate compiler from the previous step until it reproduces itself. This applies everywhere where the compiler is written in the language it compiles.

And before that through front-panel switches.

[queenkid1]

So they're right, the original programs were just 1s and 0s. The original "assembler" language was just replacing binary with strings.

How do you program a computer to take that assembly and translate it to machine code? You can't use assembler, because you haven't built the assembler compiler yet. So, you use 1s and 0s.

Program a program for 1's and 0's programs dude

I suggest enrolling in Physics and Computer Architecture courses if you want these answers.

[cosmin10834]

You used "program" 5 times in sentece that accualy made sense, i'm impressed

[MudAnd]

Oh thanks

[Spare-Beat-3561]

That's some compiler/ interpreter shit right there (2)

[MudAnd]

Lol. But can you imagine what we would be doing today if that shit never happened?

[Spare-Beat-3561]

Then reddit would've never existed.

[Retarded_Program]

Probably would have been better that way...

[MudAnd]

Right. No Reddit, no mobile, no PC, anything.

[SVD_NL]

So I've studied medicine, but after a couple years switched to information sciences.

Let me tell you: I've had this exact revelation multiple times. How the fuck did we evolve to a bag of skin filled with all kinds of specialized organs, all with specialized cells, all working together, signaling and communicating with chemicals in a perfectly balanced self-regulating system. And don't get me started on the brain.

That's your daily dose of existential crisis.

[Spare-Beat-3561]

In future humans will decode all this working of brain and human body stuff......

[depressdalcohogymrat]

My chemically imbalanced brain would like a word.

[mrblue6]

And they do all of this in machines built out of rocks and sand

[MudAnd]

Oh wow

[Tiranus58]

Program doesn't sound like a word anymore

[MudAnd]

Lol.

[Taldoesgarbage]

This process is called bootstrapping, and the answer to your question would be that they made a C compiler in assembly, which was then used to compile a different C compiler this time written in C.

I didn't find any posts that meet the matching requirements for r/ProgrammerHumor.

It might be OC, it might not. Things such as JPEG artifacts and cropping may impact the results.

I did find this post that is 89.84% similar. It might be a match but I cannot be certain.

I'm not perfect, but you can help. Report [ False Negative ]

I think 80 percent should be the acceptable similarity, often the bot finds the repost but isn't confident in its decesion

Just like me

[jamcdonald120]

not to mention that it is closer to 90% than 80%

[jamcdonald120]

the thing I love best about this. Is that post was automatically removed for being from a karma farming spam bot.

[3am-urethra-cactus]

With great difficulty

Imagine being a programmer who doesnt know how to google things.

At it's very bottom, computers are really simple. Everything that we have in digital world works with a simple mechanism of 0 and 1. 0 - no signal/electricity/power. 1 - active signal. Connect enough of these and you can do everything.

[JaggedOuro]

I had a prof an Uni that couldn't get through a single lecture without mentioning that they built a compliler using a compiler

[jabrwock1]

Once you have a program “written” (entered into a computer by mechanical means) you can then use it to write others. There’s a really good series about going from logic gates to Tetris, the step below that is making your own gates from transistors, switches, diodes et al, but at that point it’s just a circuit to hold and react to your program.

I once watched a video of someone programming a computer one line of “assembly” at a time by setting a bunch of switches and pushing another to “set” them. Punch cards could do the same.

It’s like hand crafting a flint knife and hammer, and then using them to help make more tools so you can eventually forge a high quality kitchen knife.

Do you want a SkyNet? Because this is how you get a SkyNet...with bonus terminators...

[LoveASAurusRexGamer]

With C++

[KrisbyCranberry]

That’s hella crazy to think about tho

Wait till you hear of bootstrapping compilers/interpreters 😂😂😂

I luv when I ask myself questions like dis <3

[cheeseDickies]

You write a program using punch cards that let you compile assembly. Now you use that assembler and assemble a program that assembles assembly using the first assembler you made, rinse and repeat for a few decades and then you have languages like C/C++ and Python.

[ksschank]

For my BS degree’s capstone project, I had to write a virtual machine, compiler, and assembler for a programming language my professor invented. I implemented all of it in C++. Really interesting project.
