Linux and Intel RST

[techlists at phpcoderusa.com]

Around 1984 or so there was a poster in the Army National Guard building 
in Tucson that read something like "Keep It Simple Stupid" and went on 
to say everything should be at an 8th grade level.

I was first introduced to Linux in 1998... I took my first programming 
course in 1983 at the UofA. I was already out of high school for 8 
years.

I've seen a lot of stuff.  I've watched things become increasingly 
Complicated.  I've mentioned this before. Most will shine me on.

I'm currently a PHP developer.  Over the years I have had my hands in a 
lot of related technologies.

What you describe Michael Butash sounds very complicated. Most things 
today seem to be.

Don't get me wrong, I think some advancements are good such as Proxmox 
which I use.

How do we uncomplicated all of this stuff.
