You stop assuming you can specify things in pixels. Only a very few things should directly map to physical pixels on the display, and icons, controls, text, and modal dialogs aren't on that list. Even raster images should only map to literal pixels under certain circumstances.
Sharp vertebrae and powerful acids are under the seat? Call me old fashioned (and it won't be the first time) but I'll take a trusty pair of boots, thank you.

With rockets, you have to consider mass-efficiency AND energy efficiency. They are not equal, and they are often opposed: high output velocity is mass efficient, getting the most change in velocity per particle lost, but provides little thrust for the energy input.
For example, in the limiting case of a flashlight rocket, zero mass is lost, but the kinetic energy return on radiation energy output is ~delta-v/(2c). IOW, a flashlight rocket would be great for relativistic velocities, but not so great for orbital maneuvering in the 8 km/s range.
Low velocity particles give much better thrust performance, at a cost of depleting the mass reserves much more quickly. This is why you see jet engines powering a fan to move more air-mass through. It slows down the exhaust velocity (and cools the exhaust temperature), but provides a much wider stream and more thrust. Air-breathing engines have unlimited reaction mass available to them: the atmosphere that impedes flow also provides a ready source of mass for the engines.
In space, reaction mass is limited, but energy need not be. Near a star, there is a constant radiation flux, which if you're patient can be collected indefinitely (compared to the length of the typical space-mission, anyway).
Electric drives are very relevant in space for this very reason.
However VASIMR is not an electric engine. It's a hot-plasma engine. Instead of using electric fields to accelerate particles, it uses magnetic field-lines to guide them. It is basically agnostic about the heat source, although conventional combustion is not hot enough and too high density, so the first models will probably use microwaves. But it doesn't have to be microwaves. One of the pie-in-the-sky goals is use the magnetic field to induce fusion (much like in z-pinch devices), and use that output for thrust.
College tuition has outpaced inflation for as long as I've been paying attention. That ought to be proof enough that piling on more "easy" money isn't resulting in the increased education opportunities it's supposed to.
As opposed to the direct relation between low taxes and low public spending.
Please don't confuse tax rate (the proportion of your treasure the government "asks" you remit for ostensibly public good) with tax revenue (the actual amount of treasure that the government receives from everyone it extracts it from). The latter being the one with the direct relation to public spending if and only if the government remains committed to having a balanced budget (but, where would treasury notes come from if they did?).
Tuition and Loans aren't unrelated topics. The easier money is to get for education, the more money education is going to cost: there's some lag in the supply curve due to the time it takes to train new teachers and build out new facilities, and that's not even counting administrators who look at higher margins and think about ways to keep expansions from keeping apace.
Resolution is my nit as well. But in 15 years, I'm not entirely sure it still will be, regardless of whether or not it improves...
Also, Computer displays had been getting higher resolution for a while, but for some reason OSs seem to like to stick with the "assume an 'm' is fourteen pixels wide (or some other hard-coded number)" paradigm. I want sharper text on my screen, not more text. I don't want to have to sit twelve inches away from a twenty-six inch display just because I used to sit that distance away from a fifteen inch VGA monitor (13.5 inch viewable...) (some numbers exaggerated, but not by much.)
So, I think your 15 year estimate may be a little optimistic.
Kindle already does this. The wikipedia access and lifetime cellular connection have made many people compare it to the Hitchhiker's Guide, which similarly connected many small dumb devices to a centrally stored encyclopedia of dubious pedigree but surprising usefulness.
Kindle. But I wish they'd do away with the keyboard and put in a PDA-style B&W touch interface. Something that's pretty good on power when it's on, but GUI and responsive enough for searching would be a nice feature until the redraw speed on eInk improves.
I think the argument is that DRM will fail eventually. It's a loaded gun and some day someone is going to pull that trigger. At that point it'll fail in the marketplace as the word finally spreads that everyone's geek friend was right and "they'd never do that" once again turns out to be wishful thinking. The geek friend will get no cred for this, though.
I suspect the publishing houses know this, so the question really is how long they can keep it going without actually using it.
The words don't really have any meaning among actual scientists, who are extremely sloppy with the use of the classifying terms. Apparently the elite take the quote, "Consistency is the hobgoblin of small minds" as license to not bother trying to be consistent.
Instead, ideas are classified by whether they appear in papers, conference proceedings, journals, peer-reviewed journals, the peer-reviewed journal of note for the particular field, Ph.D. Thesis, Masters Thesis, and textbooks. Any of which can trump the others depending upon circumstance except papers and textbooks, neither of which is reviewed, and both of which MUST contain ideas which no longer have support, or were built on faulty assumptions.
Because they want people to think they could do it. Suppose they shuffled after every hand, that'd do away with counting, too. But then people wouldn't get caught up in the mystique, so they just add decks to dangle "it's hard, but possible" out in front of people who think "I'm elite, so I'll be the one to do it."
Their plan is to use the buoyancy to take the urgency out of the rocket motors. If you don't need to have thrust to have a thrust to weight ratio of four, and can instead get away with much less than one, you can use more mass-efficient engines like hall thrusters and such.
Of course, that assumes that you can get up enough speed pushing a giant freakin' balloon to be able to detach and complete the trip....
To be fair, it was kind of tough to tell the scale from the pictures of it flying. Once it got close to the ground, it was obvious to anyone who'd seen that one episode of mythbusters like five years ago. But until then, there just wasn't anything to reference its size to, except maybe the skin crinkle, which would have required extensive knowledge of the material to make judgements based upon.
Well, since this is/., you take your car in for a routine oil change. The mechanic botches the job.
Yeah, that sounds about right. That's why I try to do my own oil changes when I can.
The worst, though, is the state inspection. Without fail, something always seems to fail after one of those for me. Next time I'm going to demand they let me watch the work being done.
The victims here were getting CTs to diagnose strokes. Which occur in soft tissue, in a non-moving body part.
So, the remaining reason is cost and institutional memory. That's not a good reason to put patients at risk.
What's keeping the cost up? MRI labs are glorified metal detectors. The limit should be materials cost and labor, both of which should drop rapidly as product engineers continue to improve the product.
Is the problem the word "nuclear" in nuclear magnetic resonance imaging?
CT always bugged me. You're bombarding the patient with ionizing radiation, and much more than a typical X-ray. Sometimes, even going so far as injecting radioactive elements into a patient's blood to improve contrast in your images.
Yet the CT scanner is the first 3D imager they go for. Shouldn't MRI be the default option if the patients don't have magnetic implants or pacemakers? What does a CT get that an MRI can't that justifies making it the default option?
All you have to do stick umount/path/to/guest/home/dir in the logout script. It automatically disappears in the event of a hard reboot, which is superior behavior to persisting through reboot.
The set up defines the "default" behavior in the event of unexpected trouble. If everything is working correctly, your logout scripts run fine and it doesn't matter how you set it up.

The same way you always should have.
You stop assuming you can specify things in pixels. Only a very few things should directly map to physical pixels on the display, and icons, controls, text, and modal dialogs aren't on that list. Even raster images should only map to literal pixels under certain circumstances.
Heck, you could skip the script and just alias locate
But you still run into the problem that it runs from the command line and the database is byte-order dependent.

Orbital mechanics does not work like that.

Apparently, he's against cheap power AND cheap food. The poor should starve! That'll solve the problem.

Ha hah hahh...
But seriously.. what happens to the other devices on the same bus when you plug your 1.x mouse into it?
How long does the battery last on your wi-fi enabled HD video camera?
If you have to be tethered to the wall anyway, doesn't it make more sense to use wired networking anyway?
I see trouble ahead when the "core dump" command is misinterpreted...

I would also enjoy an ePaper satellite for notes, documents, help files, quick-references, etc.
