OS X: accidentally switched my desktop to "white on black"

It took me quite a while to find the right group of system preferences, where to switch it back to "black on white": Universal Access.
Apple Universal Access is a component of the Mac OS X operating system that provides computing abilities to the blind, deaf, and handicapped.
Update 2012-10-01
It happened again (in a rather uncomfortable situation), and it took me a little to get here and read this. Success.
I don't want it to happen again, and I switch off all these Universal Access keyboard shortcuts.

that disk did not die the clicking death

When I put a FRITZ!Box 7390 in place here more than 2 years ago, one of the features I discovered with big joy and that I started to make use of, was that it powers down USB attached ATA disks after a user defined period of inactivity. You can also have a USB hub in between, and I started making use of that as well.

The ATA disk (#1) I attached, is actually a notebook disk with its own external housing. It got formatted with ext2, because I prefer that over the DOS file system.

In the beginning of 2012 that disk (#1) was no longer accessible. First I was sure, that it had died the clicking death. But when I attempted to replace it with another one (#2),
it turned out, the source of irritation was actually the USB hub, because after eliminating the USB hub and attaching disk #2 directly to the FRITZ!Box disk #2 was "perfectly" accessible again.

So I gave disk #1 another try, mounted it somewhere else, and that worked without problem.

I thought, I should note this somewhere, because it might occur to others as well.

Of course, why should live USB hubs live for ever? But I was rather, rather astonished to understand this scenario.

Well, it's not absolutely unlikely, that disk #1 will die for ever after being in use in another environment for another while. That's a behavior I found documented elsewhere.

No, the housing (external case) wasn't the reason for the problem, at least it worked with other disks.

O'Reilly Media book: What Is DevOps?

What Is DevOps?:
The continuing NoOps/DevOps controversy is a tempest in a teapot that arises from a misunderstanding of what "operations" and, in turn, DevOps, means. Both sides essentially agree about the future of operations. As more and more large applications move to the cloud, infrastructure becomes code. That's been a theme of the Velocity conference since the beginning. But operations means much more: it also means resilience engineering, reliability engineering, system monitoring, and yes, answering the pager when things break. Operations doesn't disappear; it evolves. And that evolution involves development and operations teams working even more closely together.
