OK for learning about what has been solved; kind of hacking-101. BUt the exploits involved have all been fixed in the products in that distro. What to use for the advanced class?
i have it on my VM, can someone point me to where these guides are? KDE confuses me :). i will RTFM, I just need to find it first. thanks.

It was usually used as an ultra- critical section. It would have been fine to simulate it as a scheduler-freeze for that process, preserving the meaning without getting hung up on the hardware implementation. But instead, Intel decided to try to support actually messing with the interrupt enable state, resulting in years of highly-inefficient "solutions" e.g. trapping and simulating. Sigh.
What's the (efficient) alternative?
