If the lawyers win, the market for 10GB hard drives will collapse.

Yes you do (but it is seconds, not minutes). The part of the procedure they don't really tell you about in advance is that they basically use a vacuum cleaner to suck your eyeball out of your head while they do the procedure. Actually they use suction to slightly pull on your eyeball and hold it still while the laser is doing it's work; while this is happening, you can't see out of the eye -- it all goes dark. This part of the procedure (which really only lasts for a few seconds on each eye) is fairly unpleasant and is probably the reason they give you Valium.

or any executable (and yes, if that executable doesn't understand the Powershell object pipeline, you can just hand it plain old text on standard input).

I don't think that it is frequent flying itself that reduces risk. Rather if you fly frequently, the airlines consider you a better customer. Since the airlines want to keep their better customers, they try and make life easier for customers by reducing the airline related "hassles". The airline related hassles don't have anything to do with risk. What some airlines also do is sponsor their better customers for the TSA Pre program, which does reduce risk. Risk in TSA Pre is reduced by background checks.The cost of these checks theoretically covered by the application fee that the airlines pay on their customers' behalf.

Nope, I don't do any of it. I was just saying that if you are trying to avoid being tracked when traveling by avoiding flying, it won't do you any good. I travel a lot and I assume that I am tracked a lot.

Actually if you travel a lot, the hassle factor gets greatly reduced; when you travel by air frequently, you gain status with the airlines and they treat you much nicer. You also become eligible for TSA Pre / known traveler, which lets you go back to the simple "old school" security which is basically just walking through the metal detector and running your bags through the x-ray. No more taking coat and shoes off, extracting laptop and liquids, etc. It typically takes me 5-10 minutes from the time I arrive at the airport front door to the time I clear security.

I hope that when you are driving, you don't use any toll roads and that when you buy gas or anything else, you use cash that you obtained from an ATM when you were at home. Best also not to drive through any intersections with red light cameras. You also might need to put optical filters on your license plates if you don't want to be tracked. There are lots of cameras out there.

For small scales that is true, for large, not so much. When you make a bigger rocket, you need more fuel to lift that rocket. When you add that extra fuel, you need to add even more fuel to lift the weight of the added fuel and so on. As you scale up, a higher and higher percentage of the fuel is used just to lift the fuel. There is a point of diminishing returns. I am not a rocket scientist, so I don't know at what point you hit the wall with current technology (probably not at 0.8 tons), but there is a limit to scaling with current technology. It would be more accurate to say scaling up is a matter of building a better rocket or finding a lighter fuel source. Solving these problems would have broad applications.

It may be about putting the sticker on correctly. If the sticker isn't put on correctly (positioned so automated scanners can read the bar codes and securely attached so it won't fall off), the bag may not make it to the destination in a timely fashion. Granted that putting on the sticker isn't hard, but some people have difficulty with seeming simple things. In addition, having an airline employee attach the sticker before the luggage is accepted allows for a human check to ensure things like: the bag is within dimensional limits, the bag isn't already damaged, the bag is in fact "approved" luggage that is sturdy enough to withstand air travel, etc.

are thinking about having prehensile tails now.

While I could have been more clear in my subject line, I did hint at the kinds of skills I meant in my comment text. I wasn't referring to specific technical skills, but rather more generic, high level skills -- sometimes referred to by recruiters as "soft skills". While specific technical skills (such as a programming in a specific language, brick laying, or buggy whip manufacturing) may come and go, high level or abstract skills (such as communication and problem solving), will never fall out of need.

Don't focus on specific jobs, focus on skills. Skills such as problem solving, understanding abstractions, and of course strong communication skills, both written and verbal. Skills involving dealing with and understanding people's needs will never go out of demand.

Because if you have root you can do anything (technically possible).

Doing so is really hard if you need to move power between grids - which you probably do.

I certainly hope that before we send a generational ship on a one way mission to check out one of these "Earth like" planets that isn't there, we get this right... Of course it would be a good plot for a movie.

Maybe and maybe not. There is always the chance that the firework could malfunction on it's own. Possible malfunction is one of they many reasons that in professional shows, no one gets to sit under where the fireworks are intended to go or anywhere a wind shift or malfunction may take them. I suppose if a drone collided with a mortar very close to the ground as the mortar was being launched it might alter the trajectory, but at the altitude from where the pictures were being taken, the firework has gone where it is going to go.

Acknowledged that in some smaller shows you used to be able to sit right under the fireworks and having the smoldering hunks of cardboard rain down on you. This was kind of cool, but in my experience, hasn't been an option for a long time.
