Kilo

is it possible to completely write a OS with C++ (no ASM involved)??? (not that i don't like ASM lol, i love it ).

No, many critical parts of the kernel must involve asm. You just have to get down and dirty. Interrupt handlers, process switching, memory management, controlling hardware, and others either require or benefit from asm at some level.

I'll admit it. I am dumber than a sack of hammers. What on earth would posess someone to want to write their own OS? Isn't that a bit like wanting to perform brain surgery on one's first day of med school? I'm presently rolling code for Djikstra's algorithm, and that is painful enough. There are so many other interesting problems to try and solve that I can't understand the desire to write an OS.. I can't even begin to imagine how difficult that would be.

Don't get me wrong Kilo.. I am in no way being critical of you. I just don't understand the fascination with creating one's own OS. Is it a "my dick is bigger than yours" kind of thing?

The reason I wanted (and still want) to do it is the feeling of almost complete control you have over your computer when there is almost nothing but your own code running on the machine. Also, I thought it would help me learn quite a bit too.

That's my reason, anyway.

Had Linus never wanted to prove that 'his dick is bigger than yours' then we wouldn't have Linux now.

Thank god Linus has a tiny penis, I hate windows.

I can see grovicus's point here. I think what he's trying to say is that you should try and learn easier things first and slowly grow to the level of writing an OS. Yeah, I myself want to write an OS but I don't think i'm ready for it right now. I need to learn a lot( like asm) first.

Exactly... there is a difference between filling a need (such as 'nix), and just wanting to write an OS because it seems like the cool thing to do (Again Kilo, this is not about you at all, just me exploring motivations). There are so many threads that read something like "I just started programming..I want to write an OS, or a really cool game". I can't imagine the frustration they must feel when they realize that it is way beyond their reach. (or how often that kind of frustration puts someone off wanting to pursue programming at all).

the only reason i would ever want to write a basic OS, would be for knowledge. For the pure sport of learning and breaking down computer architecture.

EDITgroov: i think about 6-7 years ago i used to be one of those noobs wanting that kind of satisfaction. What i did was re-wrote those programs a hundered time learning a little bit every single time i wrote the damn thing.(IRC client for example). And yet to this day i still re-write the programs i used to back in the day (client->server apps, irc clients, directX based games and such).

I've got a bit of a question... what is ASM? Is it Assembler? I think it might be but I could be wrong.

Benoit

You are correct, its Assembler
