Re: Parsing ELF Executable

I might be able to help, but you'll have to wait until Monday, sorry. I won't be able to access the computer my code is on until then, but I loaded an ELF kernel recently, and maybe my code can help. [edit] Well, I just looked over what I had, and I don't think it will help. Let me ask you this, tho...

Re: How many people are working on the Neptune OS project?

I am wondering, how many people are working on the OS the actual Neptune Operating System (OS), and then they share the amazing tutorials. I believe Mike is the only one working on it, and since it's an in-house project, I doubt he'll be releasing any information about it. Are you sure? Can really ...

Suggestion: List of Updated Files

Mike: I was wondering if you could start adding a list at the end of each chapter (no need to go back and do this to old chapters, just begin now) which lists 1) all the new files added to the project, and 2) all the updated files. I have a few different projects going, and one of them follows your ...
