US military has been working on this for a long time and a lot of the research is freely available. For example, multi-hop wireless networking has known scalability limits (you can't connect everybody to everybody because the system slows to a halt, a few hundred nodes is probably the limit) so you need a certain percentage of basestations that are better connected via microwave links or wire lines. Store-and-forward helps with disconnection but is very slow and how do you secure such a persistent connection or decide when it should be dropped? How to only partially trust a newly discovered remote service? (See papers on mobile agents and execution on servers that are assumed to compromised.) . I haven't looked at this area for a while, but I think the state of the art is basically what the US uses in warfare, which is small, local multi-hop networks connected to mobile basestations that connect to satellites with encryption on everything and some jamming resistance. How to distribute encryption keys is always a question; you can cooperatively generate a shared key with a remote connection, but how much do you trust them? How do you trust de-centralized services? Reputation systems can help trust be self-healing. At the least some sandboxing is required at multiple levels of both the networking systems and operating systems, including the ability to reset a system back to a known state (e.g., boot from CD-ROM). There are a lot of difficult questions, and ultimately everything relies on people, so it will never be perfectly secure, but some kind of verifiably-fairly-trustworthy-most-of-the-time system that can self-heal-eventually can probably be cobbled together. Opening up long range radio bands to open-access-networking would be very useful for decentralization. Notice that in the US citizens have little access to open and hackable long-range-wide-area radio links that can carry any kind of content. Cellular and Ham radio is fairly tightly controlled as are high power emissions in any band. Ultra Wide Band might be useful for solving the problem of sharing wide area radio links without bad actors destroying the shared resource. Bouncing signals (laser or radio) off the moon is limited to when the moon is above the horizon (and not obscured by trees or buildings) and is tricky to do. Maybe a grid of big metal reflectors in orbit that everyone could bounce signals off of could work more predictably than bouncing signals off the ionosphere?
There are no good books unless you include religious texts. I've been coming up with ideas for 18 years working in research at a college and the things that help me are: writing down ideas as soon as I get them (always have paper and pencil handy, even at night and when showering and traveling), absorbing knowledge from everywhere (read farm catalogs, listen to the lyrics of music, delve into sociology, psychology, physics, chemistry, business processes, finance, everything), and get rid of clutter in your mind (simplify your life, have good interesting friends, meditate.)
Assuming water is catalyzed to produce the hydrogen, what do you do with all the oxygen generated? Release it to the atmosphere so it can later combine with the hydrogen for a net zero contribution of oxygen to the atmosphere? But the oxygen gets released locally, while it is consumed globally, which would likely create local imbalances. With large scale production that local imbalance could be significant and affect people and plant growth.
Retaliation from Russia? Obama said we would retaliate for the election hack. Maybe now the Russians are retaliating against that retaliation. There have been quite a few outages of big cloud services lately.
If we don't need more engineers then it must be that most of our engineering problems have been solved, right? There must be no big problems left in the world that require engineers.
Why use obsolete rotating optical disks when physical music distribution could be on microSD cards? Seems weird that I can't buy 100 4GB microSD cards really cheaply to use for purposes like this.
Also, does this mean all electronics that could be used to build a drone have to be registered and controlled? A smartphone could be the controller in a drone, wireless modules can control drones, servos can actuate drones, FRS radios could be used as comm channels, etc. Even registering a drone doesn't stop anyone from misusing it if they're willing to suffer the consequences, or it being stolen to be misused. For after the fact tracing it would be necessary to include an unremoveable ID number somewhere inside the drone, which requires an almost perfect purchase/registration tracking system and still doesn't stop misuse of a stolen or wirelessly hacked drone. This move seems more like security theater than any real attempt to solve the problems. Haven't we already gone through all this with large scale hobbyist rockets? Maybe some criteria like, if it's big enough to show up on radar or flies above a certain height (again as seen on radar) then the police are called in to try to track down the owners (unless the owners have preregistered their flights.) If it's an immediate danger then zap it with some microwaves; Star Wars weapons don't work against ICBM's, but they probably would against drones within a few kilometers range. You know the military is developing things like this, they've already demonstrated shooting down drones with lasers; protecting airports would give them opportunities to test them (and a microwave beam is probably safer than using lasers near an airport). Simple RF jamming would probably be sufficient to deal with most hobbyist drones.
Would it be possible to run license plate scanning software on smartphones? Along with face recognition software, gait recognition software, body height scanning, etc., and give everyone the ability to track everybody in public? There is open source plate tracking software already available. Maybe if everyone could do it the recognition for the need to limit it would become obvious to more people.
Good point. Also, what happens to the video later? Is it all stored and processed automatically to track everyone in camera view? Used to find suspects among those who were recorded "near" a crime? Can any or all video be subpoenaed by any lawyer?
A Kinect and other sensors could be used to scan -everything- in public places. Eventually it will be possible to infer the health of politicians, the mood of CEO's, the anger level in police, and the amount of panic everyone feels in an economic recession. There are no laws at all about scanning people and anything else in public with sensors (except microphones and sometimes cameras). Add some machine learning and imagine the databases you could build and sell!
Doing medical sensing, making sure the data is accurate, especially in a mobile setting where the sensors are subject to movement, and understanding what the data means (mostly only astronauts have ever been subject to continuous medical sensing) are not easy. If they are just hiring experts now it will be a year or more before they have even a basic handle on the issues involved. If they want something FDA certified with data that can be easily digested by doctors it will take at least several years to bring a product to market. If they are just building another fitness device they probably already have it working. Possibly they'll try to position some medical-like sensing as non-medical so they don't have to get FDA certified and can avoid liability by claiming the device and apps are not intended for any medical/health purpose.
The article quotes the NSA as saying "We do not use foreign intelligence capabilities to steal the trade secrets of foreign companies on behalf of --- or give intelligence we collect to --- U.S. companies to enhance their international competitiveness or increase their bottom line." however the intelligence is requested by congresspeople and the congresspeople may be requesting the intelligence to help US companies. So the NSA has deniability to say they don't spy for US corporate interests, but those requesting the intelligence may be doing exactly that.
It has a red, green, and blue LED and three buttons which let me control the functions which include:
* strobe frequency from 1Hz to 5KHz
* random blink mode, also frequency adjustable
* individually adjustable intensity for each LED in 255 steps
* on/off for each LED
* automatic sleep or continuous on
* low power sleep
The strobe mode is useful for finding the rotation frequency of anything that spins. The on/off and intensity settings are applied to the strobe and blink modes, so if you want a bright 4Hz red strobe or a dim 60Hz green strobe it's easy to do.
To get an idea of what a transformer fire is like and
why they are so difficult to replace, here's a picture
of a transformer burning due to an oil coolant leak in
it's outer shell at the Vermont Yankee nuclear power
plant, as well as a closeup of a transformer:
However, observations of the sun and magnetometer readings during the Carrington event shows that the coronal mass ejection was travelling so fast it took less than 15 minutes to get from where ACE is positioned to Earth. "It arrived faster than we can do anything," Hapgood says.
so a replacement for ACE won't help. Rather than launching an expensive
satellite, it sounds like the solution is to build more spare
transformers and train more installation crews.
Library supply houses have a variety of improved CD cases. Demco (http://www.demco.com) used to sell polycarbonate ones (i.e., bulletproof glass) which were fantastic, though expensive, but don't seem to carry them any more. They do have a selection of polypropylene ones that are still better than the usual polystyrene (enter "cd cases" in their search engine). This site has links to a few other vendors:

That small grey thing at the far lower left corner under the transformer is a bucket, to get an idea of the size of the thing.
