Re: color background
Agree. I have profiles for my terminal software for about a dozen or so foreground/background combinations. If I have something that cannot be the subject of a mistake, it goes in the white on red window.
The youngsters in my office laugh at this and would rather use other (unapproved) software that either doesn't offer a way to store multiple profiles easily or that they can't be bothered to learn how to use properly.
One of the bright young things, working in a forest of white on black consoles, restored pages from a test database over our production database and caused a complicated partial outage that lasted a week while we sorted it all out.
Another Young Genius obliterated a QA cluster under the impression he was working on a dev system.
Yep. The problem is The Old Guy doesn't "get it".
