Hey nothing in his post suggests he is anything more than someone posting for a laugh, there is confusion between OS and Programming language, there are terms that are not related to anything really (such as mac) he suggests using parts of other OSs, which is pretty pointless as they are protected under copyright and other licensing laws, he offers up a term for an OS that already exists (existed anyway). And what best parts of M$ Windows XP and Mac OSX? The best parts of these Operating systems were originally part of BSD (opinion of course).
There are no details on what the Operating system is going to do, how much technical knowledge he has, and what this OS is designed to do that cannot already be done elsewhere. In fact all those things exist in Linux already.
Also no statement on what license the release is intended, if it will be for sale, and what type of architecture it will be compiled for, what hardware the OS is going to need for it to run, if not generally available.
Also there is the calling it a DMS (Disk Management System), that is not really important, it is a minor part of what the OS does.
The poster is either really really taking the piss, or needs to drop a chill pill, step back and breath deeply, research the computing world a little more and then work on writting a file management tool, because it seems that is what he really wants.
If the poster is a wonderful coder, and has some ideas he wants to implement that is great, but in the past few months there have been a number of posters who have had that most revolutionary idea, of writting a new OS - Just like Linus. The reason Linus got where he did was that he did something different, did it very well, and did it because it was his hobby/fun/prefered waste of time.
There are already hundereds of projects on source forge looking for developers, coders, etc. and if these people want to help them then that would be a much more constructive area to offer their skills and ideas. And if their unltimate goal is to write an OS, then great that would teach them much more about how an OS works.
This is not meant to be some harsh bashing of the write an OS idea, but I feel the original poster is diving in the deep end. Writting an OS takes and incredible amount of knowledge, and it strikes me that the poster has not gained the rudiments of that knowledge...yet.
