The coding in binary code and assembly is necessary currentl

Well I don't think the devs actually program in binary.

But for the second question, I don't even know of any bare-metal software that doesn't have at least a little bit of assembly. There's very specific things you need to do, like getting the x86 processor out of real mode and setting up the bootloader. I never developed an operating system but I'm sure there's a few more things that are impossible or impractical to do in C.

That's what the Hardware Abstraction Layer in NT is for anyway, so you can write that platform-specific code and not worry about the rest of the OS being dependent on that platform.

We have plenty of ASM Code where it's needed badly, like in the example Konata mentioned. The rest is WinAPI C / C++.

Like Emuand said ROS is written in C, C++, and API calls, there's only a bit of Assembly where it's required. And nobody writes in binary, the lowest you could go is hexadecimal. Most CPUs take hexcodes and turn them into binary directly, they've been doing that for decades. But everyone uses Assembly because writing in hexadecimal directly is insane.

That's not *entirely* true. There are rare instances where some freaks code in binary. It's a niche-thing and extremely rare; a fringe activity, thus, but it is/can be done, still.

You can search the internet for a few examples (and even tutorials). But even then it's clear it's a real hard-core thing, and normal humans usually go only as far as Assembly.

As I said we use C language and some rare assembler code. ReactOS aims to be portable easily. I personally see no use In binary code for one CPU type. But ask the other developers too.

Just a random thought: could clark_hobby's skills be helpful for an x64 or an ARM ports?

[EmuandCo]

Depends on what assembler he is talking about.

Assembly would only be used for very small bits of code. What's more valuable is actually understanding the underlying architecture.
