It's hard to disagree with this statement, although we do not know all the details. Compare to computers—we have insecure OS's running insecure servers on insecure networks, and then people realized that maybe all this should be retrofitted with security without losing a single capability or backwards compatibility. That's definitely hard. On the other hand, we have had cars secure from RF-based attacks for a hundred years, and now suddenly they become insecure without the addition of a single meaningful capability.
I could duck tape an ipad to the dash of my 10 year old car and have something more capable and more secure than a 1 year old car.
Whether the commands to the virtual device are sent to an open port 8000 or sent encrypted over an ssh link doesn't seem to be particularly important. It's the initial step of being able to connect any GUI to an arbitrary virtual display that is key. True, X with no security and an open port 8000 allows anyone to start an X client on the display with no local account needed, but I haven't seen this in use since the demise of the X terminal (good riddance. anyone want one? I need to clean out my office).
It seems likely that if Wayland compositors support a version of Xnest, then effective networking will work. But it's the initial level of abstraction that is needed.
Saying that X support will continue as long as codes support X is truly begging the question. The problem is the next time serious modifications to a code are made; in most cases, if network support doesn't happen for free, the developers will not bother.
Who the hell decided to call something "Dell Venue 8 7000"? You don't put two numbers one after another, it's just stupid!
Time to fire the marketing guys!
Sounds like an old phone number. Like buying a Dell Pennsylvania 6-5000.
Yes they do. For a stable society, the public at large must believe that trials are decided justly.
No, and that proves the point, because trespassing means entry without permission. Guests are not permitted to trespass--they are not trespassing by definition. Furthermore, "No Trespassing Signs" frequently cite specific state laws that govern their meaning and interpretation.
Is the assumption that trespassers carry a copy of the state code in their pocket? No, the purpose is to place people on notice that their behavior is governed by specific laws and they are responsible with learning and following those laws. That's all the NFL needs to do.
Of course. That is why the NFL is being intentionally misleading when they refer to "Any other use of this telecast or any pictures, descriptions, or accounts of the game." They use the phrase "any other use," not "any other use except as permitted as fair use under copyright law." A rational person, not acquainted with the ins and outs of copyright law, would assume that they have no right to repeat a syllable of what they hear.
I have found that showing the TSA agent the rules printed from the TSA website is a waste of time, but being calm and polite can sometimes get them to change their minds.
A device generating 100 MW of fusion in that way would be using 10s of MW of power for magnetic fields and RF generation, enough to run a small town (if only for a few s at a time). This would be a major facility. Not to mention that it would be permitted and inspected like any other nuclear power plant.
There is a huge number of hard issues to deal with if a device starts making MW of fusion power. Just MW, not 100s of MW. At 100 MW, most superconducting magnets are wrecked, special vacuum pumps for dealing with tritium are needed, immense neutron shielding is needed, wires and structural elements become embrittled, fiber optics are browned...The obvious absence of any mention of these tells us just what level this device is operating at. Not saying it won't work, but that the step from making a cold plasma to MW of fusion power is not a small step.
They do have a huge problem that no one was able to solve. It is not inconceivable that someone who understands the problem will be able plug the ends. But step one is to explain why this mirror would work differently from those mirrors.
The geometry and stability arguments make this look like a variation on a mirror, and people figured out the advantages and the disadvantages of mirrors a long time ago. The instabilities that dump power into the unconfined particles are not always obvious until you know to look for them, so until they ramp this up to a couple keV, there is no telling if it is promising or not. Maybe with modern technology, they can make it work.
It is! Nontechnical discussions aren't very good at differentiating between three somewhat different areas of concern. First, neutrons and gammas produced by the reaction need to be shielded but go away when you turn the reaction off. Second, short-lived activation in which materials are radioactive, but with a half-life of years or less that becomes safe in a reasonable time. Fusion reactors have both of these, but they are manageable. Third, fission leaves behind nuclear waste materials with a half-life in tens of thousands of years--this is nasty stuff and is around basically forever. Fusion produces no long-lived waste (there is probably some component of some alloy that will prove to make tiny amounts of bad waste, but nothing significant compared to fuel rods from fission reactors).
