Hi,

Since whenever I became a little more experienced in OS Dev (not that I am much experienced now, but I guess I've improved), I've been toying with the idea of writing a lengthy tutorial to get someone started well in OS Dev. However, my idea wasn't to write something which was standalone - one could pick it up, and write a OS in a week. My idea was to write something which taught how to make important design decisions - such as Own bootloader vs GRUB, and benefits of both. Then, I'd branch off to: A one-stage bootloader vs a multi-stage bootloader or something; and a Intermediate Loader after GRUB vs simply the kernel and so on and so forth. Similarly, for the kernel, I could do Microkernel vs Monolithic and the benefits and such.

Of course, the above would be a very very thick book, and would be time consuming. What I was thinking was to base it on my OS - so, I describe the other alternative briefly, and then dive into the alternative I choose. Currently, I do maintain a small notebook, in which I keep my ideas and stuff. I draw flowcharts to think about algorithms and write about decisions I made that day. Similarly, I could maintain another notebook which would be this "book", in which I'd add major designs each day.

tl;dr I'm thinking of writing a book on OS Dev - more of a long tutorial on DESIGNING a OS, and not WRITING one. What do you think about the idea?

I'm not too sure how to interpret that: good idea, bad idea or already done (OSDI perhaps - but I think mine would be a lot different)?

five seconds of google.

I think there's lots of good material out there already. However, if you feel you need to contribute to the community, you should instead give the wiki some more lovin'; it makes more sense to improve what we already have than to create many sources that all cover the same basic things.

But I do see one good thing that could come out of your teaching effors: You'd be answering some of the questions you should've thought of but never have---it happens to me all the time when I'm trying to explain difficult subjects to other people, not necessarily related to computers.

Yeah, I suppose some.

Happens to me too, on the IRC channel. Thanks, anyway. I'm that sort of a guy which has several hundreds of thousands of ideas each day, and gets diverted a lot. Hard to focus on anything for a long time, but this OS Dev project has been keeping me interested since last year (though I still do get diverted for weeks in between). I'm not too sure if everybody has that problem, or I'm the only one..

Sounds like a mild case of ADD to me...

So there's someone like me! Cool!

I find that essential too. But you see, I'm too inexperienced. I got too much to learn, and so, daily, I get so many ideas which I CAN implement, and so, I get temptations.. Hmm. Any ideas to fix this bug?
