How Unix Works

This is a very good explanation. However, I think it would have been helpful if the author had provided some comparisons with how other operating systems do these sorts of things, and why its designers made their particular choices for Unix. Or maybe that could be another article he could link to.

A very nice overview. Now knowing all this isn't necessarily a prerequisite for getting a lot of stuff done, but I think it's very useful indeed. In my experience in the industry so far I find that most people don't know any of this and just implicitly rely on the magic going on underneath and just interact with higher level interfaces, but when things go wrong then they're stuck and rely on Google or Stack Overflow for answers, copy and pasting solutions without really knowing why it works. This is fine of course, some people might not be too interested in this aspect, and just want to solve that blocker and move on with their task, but for me it's essential.

Thanks for sharing and well explained!

I wish I had read this years ago. It’s very hard to find sensible high level overviews of technical things like this. Excellent.
