I think that's part of what courts are struggling with in applying copyright to the Internet. So much is very short, often shorter than most newspaper columns. Just for thought - is someone's individual posts on a group like this one a "work," or is the "work" really some collection of posts. So...

"Pound" does indeed have two formal usages. Look up "pound-mass," Imperial measure of mass (usually defined in terms of kilograms), as opposed to "pound-force," the engineering measure of mass being affected by gravity. Both are spoken of as "pound," and both are commonly abbreviated as...

I had no problem with my Tusa Liberator sealing. I got a Promate for a backup Rx mask and found I had to shave the smallest space under my nose to make it seal. So for me, it's a matter of mask design, and the difference was so slight that I suspect a bit of wax or silicone grease would also...

Not a lawyer myself, those that I am surrounded by all day are the criminal variety. But this sort of thing gets thrashed out among writers all the time, and I've been involved in a lot of that over the years. From what I've seen, first, you dodo own copyright and did from the moment you wrote...

I can see the point of making it more certain that people you're trying to show sharks to the end of appreciation and having them and the governments that enjoy tourist income support protections. But it feels wrong to me. It's not quite like feeding bears in a park. Bears are much easier to...

That depends on how you think of it. "Pound" is generic. Pound-force or pound-mass are more specific. I said mass, because we commonly talk about weight and weighing, and weight is mass times gravity. Of course, the ISO definition is mass times [I]local[/] gravity, and that kind implies...

Of course, if you want to get picky (and you know how we love to get picky), if depends. The weight of any part of the aquarium/water/log system is a function of mass and gravity. The gravity part changes with distance from the Earth's center. That distance from center varies with location...

Yep. And where the heck is my flying car?!! I was promised, way back in about 1958 that I would certainly be commuting to work in my flying car by the 1980's. (My robot maid/butler also doesn't seem to have worked out as promised, either.) And I recall reflecting on the possibility of seeing...

Okay, books. That's my thing. These are some I think are good, for one reason of another. I read a LOT and tend to read a lot on the subject of anything I'm doing. Look the up on Half.com for cheap deals. Diving Science (Straus and Aksenov). If you want to know how the body copes with...

Yep. A horse is worse than a boat. The boat is just a hole in the water into which you shovel money. The horse is just as big a money hole, but what comes out the other end isn't something you have to deal with in a boat. But I wouldn't call scuba expensive. I would (and have) put perhaps twice...

I guess I'm pretty tolerant of a loose grip. I had read of jaw fatigue, so on my first dive, I took some time to focus on how I was doing it and found I wasn't really putting much into it. I seem to let the mouthpiece move around a lot. Just not feeling the need to consciously bite. But getting...

Granted - Here it is, but here I am delivering it first. Granted, but your filling fell out and eating anything cold is agony. I wish my next wish would be granted.

We just ask the nearest soft drink wench for a sip.

Well, that's the point, isn't it? To not lose big. Buying used without returns rights, which is usually the story on CL or eBay, means there's a chance you might lose, if even only because the seller doesn't know enough to detect a flaw. So you look for prices accordingly. And it's good to...

After reading the accounts in the "bad buddy" thread, obviously you can't always maintain contact with a "buddy." If they take off into circumstances that were not agreed on and were not within your own qualified comfort zone, you'd be foolish to chase them into a spot you don't want to be be...

You didn't ask for advice, but I'd consider hiring an instructor to do some skills development with her or see if a refresher course would do that. Since she is just now deciding to get on board with you, I presume she wasn't chomping to dive all along. Given the probable not quite clamoring to...

I think a lot of this has to do with how confident you are in your ability to research gear and with how comfortable you are taking the chance that something might not work out. But I don't think there's really much you can do about gambling on your choices, no matter where you buy it, unless...

Note that AHA and other CPR standards organizations move very slowly. The advantages of uninterrupted compressions has been demonstrated in studies for many years. This is not to say AHA, et al., are too slow. It's quite a major thing to change standards, and the fundamental problem is not one...

I was going to, but the whole project just got entirely out of control.

It would, in fact, be hard to think of a more appropriate place for an AED than a dive operation. I can't think of anywhere else more prone to encounter the ideal (if we can call it that) situation. A respiratory arrest from mechanical cause, likely sufficient duration of respiratory arrest to...
