Hardware, Embedded Systems "In this article, I show at the transistor and silicon level. I've discussed the mathematics of the 6502 overflow flag earlier and thought it would be interesting to look at the actual chip-level implementation. Even though the overflow flag is a slightly obscure feature, its circuit is simple enough that it can be explained at the silicon level."

AIX isn't Linux (or was that a separate point you were making?)

I know what you mean though. I'm a Linux and UNIX administrator by trade, and these days I struggle to fix even basic Windows problems. Back in the days of XP (and every version of Windows that preceded it, both NT and DOS branches), I knew where everything was and how to fix many of even the most obscure of errors. But the last version of Windows I ran at home was Win2000 (I was only familiar with XP because of the similarities) and since then Vista, 7 and 8 have all changed everything around. Now I struggle even just finding networking control panels (in fact I don't understand how people prefer the new control panel layout as it's a nightmare if you know where you want to end up but not what hyperlinks you need to click to get there!)

Thankfully Windows does have some CLI tools which have been pretty static over the years. But there's a hell of a lot in Windows which doesn't have a CLI to and I end up having to guess to find the GUI on the rare occasions I am called up to fix a Windows PC (which, thankfully, is very rare these days)
