Batman no; Spiderman maybe. I can remember at least once he was out in LA introducing himself as "your friendly coast-to-coast Spiderman."

About three years ago. All went well and my vision is much improved.

Aphakia is the absence of a lens, either congenital or through surgery (e.g. cataract sugery).

I have had cataract surgery in both eyes, but I don't have aphakia. In both cases, I had artificial lenses put in that completely corrected my astigmatism and changed me from being severely nearsighted to slightly farsighted. (I need reading glasses for closeup work because my minimum focus is about two feet.) My ophthalmologist was slightly disappointed because I didn't quite end up with perfect vision. I know a number of other people who've had cataracts removed and all of them now have artificial lenses.

I can now claim to be at least partly bionic because I have ocular implants and adjustable augmented hearing.

I too am certain that I'm not color blind. If I were, I wouldn't have been able to serve in Uncle Sam's Navy.

He's quite right, as you can see here.

...why does GNU's documentation still only document the differences?

I'm only guessing here, but it seems reasonable that much of that was written back in the early days when most people using Linux had migrated from one or another form of Unix and all the users needed was a list of differences. Then, of course, other people copied that form of "documentation" under the impression that this was what was expected of them.

Linux has won. Most Linux users have never used a traditional Unix, and most never will.

You say that as though you think it's a bad thing. Think of it as evolution in action.

Huge dinosaurs disappeared, for the same reason huge battleships did.

Wrong. Battleships were so big because they needed to be to carry what was then the most effective weapon available: high-caliber, long-range gunnery. By the end of WWII they had been rendered obsolete by the development of effective naval aviation, carried on aircraft carriers that are even bigger than battleships were.

How? Even if the border patrol blocked the entrances on the US side, the owners could always provide a door on the Canadian side and there's no real way to stop people from going into Canada and using them. And, as the tavern was a Canadian business, American LEOs wouldn't have had any jurisdiction as long as the sales were made on the Canadian side of the building.

I've had to clean up my desktop after an upgrade didn't finish properly and I only had a CLI to work with. Knowing how to use at least one non-GUI text editor and having that editor installed already was a life saver because without it I couldn't have gotten the network up again and without that, I couldn't have installed an editor. Remote admin is one good reason to know how to work without a GUI, but it's not the only one.

I've been using nano, or as I like to call it, "Mork's editor," for a number of years when I've needed (or wanted) to do text editing in a CLI environment under Linux and I've never had a bit of trouble with it, even with line endings. You just have to remember that in some places, such as /etc/fstab, you need to make sure there's a /n at the end of every line, including the last one. Of course, my bashrc includes alias nano='nano -w -m' which may well explain why I've had such good luck with it.

I remember reading that back during Prohibition, there was a tavern that was built right over the US/Canadian border with the bar stools in the US and the bar itself in Canada. That way, if/when US law enforcement came in, all the customers needed to do was put down their glasses and lean back and there was nothing that could be done about it.

... And don't have other options.

In my case, Glypizide, Metformin (pills) and Lantus (injected) was doing a good job. However, there was always the possibility that mealtime insulin (instead of Glypizide) could be better. Alas, it wasn't, but at least none of the problems were catastrophic, and now I know.

I'm not sure how well it worked for her, but I'm glad that my trial's over and I'm back on my old treatment. Not only did I find myself obsessing over how much and when I was eating, I had vastly more hypoglycemic episodes than normal. (Of course, at least half of them had no symptoms other than a low reading, so I can't be sure.) I know that mealtime insulin works for many people; now I know that I'm not one of them.

Shrug! Even if I were part of the control, I'd still be doing something to help.
