Programmer Humor

Open source ≠ free software

And even if you had the source code it may not necessarily qualify as open source.

It's still called programming, coding is the same thing. Assembler more commonly refers to the utility program that converts the assembly code to machine code while assembly refers to the code itself, but the term assembler code is also valid. It's uncommon to simply call the code assembler because it would be easily confused with the utility program.

Yep, some call it assembly, others call it assembler

I thought that the assembler is a specific program that translates mnemonics into the corresponding machine code. Perhaps in early computing this was done by hand so a person was the assembler (and worked in assembler), but now that is handled by software (and supports various macros). So programming in assembly would generate a stream of text that must be assembled by an assembler. (Although I have heard people refer to programming in assembler as well, just not often.)

I can't wait for AI to make a PC port of every console game ever so that we can finally stop using emulators.

It was a staple of Asimov's books that while trying to predict decisions of the robot brain, nobody in that world ever understood how they fundamentally worked.

He said that while the first few generations were programmed by humans, everything since that was programmed by the previous generation of programs.

This leads us to Asimov's world in which nobody is even remotely capable of creating programs that violate the assumptions built into the first iteration of these systems - are we at that point now?

You moved the goal post! No fair!

The first computer I used was a PDP-8 clone, which was a very primitive machine by today's standards - it only had 4k words of RAM (hand-made magnetic core memory !) - you could actually do simple programming tasks (such as short sequences of code to load software from paper tape) by entering machine code directly into memory by flipping mechanical switches on the front panel of the machine for individual bits (for data and memory addresses)

You could also write assembly code on paper, and then convert it into machine code by hand, and manually punch the resulting code sequence onto paper tape to then load into the machine (we had a manual paper punching device for this purpose)

Even with only 4k words of RAM, there were actually multiple assemblers and even compilers and interpreters available for the PDP-8 (FOCAL, FORTRAN, PASCAL, BASIC) - we only had a teletype interface (that printed output on paper), no monitor/terminal, so editing code on the machine itself was challenging, although there was a line editor which you could use, generally to enter programs you wrote on paper beforehand.

Writing assembly code is not actually the same as writing straight machine code - assemblers actually do provide a very useful layer of abstraction, such as function calls, symbolic addressing, variables, etc. - instead of having to always specify memory locations, you could use names to refer to jump points/loops, variables, functions, etc. - the assembler would then convert those into specific addresses as needed, so a small change of code or data structures wouldn't require huge manual process of recalculating all the memory locations as a result, it's all done automatically by the assembler.

So yeah, writing assembly code is still a lot easier than writing direct machine code - even when assembling by hand, you would generally start with assembly code, and just do the extra work that an assembler would do, but by hand.

Yes, you can code in machine code. I did it as part of my CS Degree. In our textbook was the manual for the particular ARM processor we coded for, that had every processor-specific command. We did that for a few of the early projects in the course, then moved onto Assembly, then C.

Assembly effectively is coding in binary. Been a long time since I've looked at it, but you'd basically just be recreating the basic assembly commands anyway.

I guess you could try flipping individual transistors with a magnet or an electron gun or something if you really want to make things difficult.

If you actually want to one-up assembly coders, then you can try designing your own processor on breadboard and writing your own machine code. Not a lot of easy ways to get into that, but there's a couple of turbo dorks on YouTube. Or you could just try reading the RISC-V specification.

But even then, you're following in someone else's tracks. I've never seen someone try silicon micro-lithography in the home lab, so there's an idea. Or you could always try to beat the big corps to the punch on quantum computing.

You can code in binary, but the only thing you'd be doing is frustrating yourself. We did it in the first week of computer science at the university. Assembly is basically just a human readable form of those instructions. Instead of some opcode in binary you can at least write "add", which makes it easier to see what's going on. The binary machine code is not some totally other language than what is written in the assembly code, so writing in binary doesn't really provide any more control or benefit as far as I'm aware.
