Re: Strap a phone to it...
Could the accelerometer from a mobile phone be used to make a 'good-enough' inertial guidance system? It doesn't have to be very accurate , just enough to continue the flight path beyond jamming range.

I tried a laser lawnmower. I think I may have scared my retina with a reflection, but didn't cut the grass effectively. There's a problem: Even dead plants have a fair amount of water in them, and it won't cut until you've evaporated the water out, which takes too long for just slice-and-cut to work.
Japan's approach to censorship was to avoid ambiguity by specifying in law exactly what was and was not permissible - a notable contrast to the US definition of obscenity, which was simply a reference to typical community standards. Legally it looks like a better solution because it avoid long legal battles over just what is obscene. A strange side effect though: When you tell porn producers exactly what they are not allowed to show, they get quite creative in finding new things that the authors of the law never imagined.
Throw this in together with a culture that never got the Disney legacy condemning animation as a genre only fit for children, and... Japan. The law may say that genitals must be pixelated, but it doesn't say anything about tentacles!
For a time Playboy Japan carefully airbrushed out any sign of pubic hair, because it was on the 'thou shalt not show' list.
The magnetron is the kazoo of radio transmitters. You do not try to tune it delicately for a precise output - you calibrate it for more-or-less what you want and make do with the very broad spectrum it puts out, hopefully centered roughly where you want. They also operate at very high power, and depend upon the screening of the microwave oven to hold the field where it belongs - so the slightest imperfection in containment turns it into a wide-spectrum 2.4GHz jammer.
It's not unheard of for such situations to occur in the US - the way they split power between different levels means that one part of their government is often actively trying to oppose another. Sometimes it leads to such oddities as classifying pizza as a fruit, occasionally to something more serious.
A sex-bot does not need to express emotions as we know them. A sex-bot needs to be able to mimic emotion sufficiently well to convince a user who is already trying to convince themself. That's not such a hard goal.
The tricky part is going to be programming it to carry out the two-minute conversation that counts as foreplay and accurately interpret commands from an operator who might be uncomfortable stating outright their desires.
If they became semi-commonplace - say, about the same as the more exotic sex toys today - it's not hard to imagine a community of sexbot hackers online exchanging printable upgrade designs and new programming. People mod their PCs for cosmetic reasons, so think what you could do with a sex-bot. However exotic your tastes?
Fan of Avatar? Then you'll want to get your stock Cherry 2000 model, download a new voice pack and behavioral profile, print yourself a new facial plate. The skin is going to be harder, but you should be able to order roboskin intended for animal displays, and the eye lenses along with them. Might be a bit of a hack job, but doable.
Just think of what the furries alone would do! And then go bang your head against a wall until that image departs your mind.
I think he was referring more to the scenario of 'Rise of the Marching Morons' or the movie 'Idiocracy.'
Intelligent, rational people use birth control, and breed only when they are emotionally ready, have a stable long-term relationship and have sufficient long-term career prospects that they are confident they can properly care for their offspring.
Religious nutters think contraception is a crime against their God, screw like rabbits and accept every child as a blessing confident that God will make it all work out somehow. Given enough time that would lead to natural selection - genetic in the very long term, but cultural in the short term, as most individuals take on the cultural and religious views of their parents. So within a few generations you find that simple reproductive advantage shifts the population in favor of those views which discourage of prohibit contraception.
Actually grounding the ground at both ends isn't always a good idea. It can do weird things when long cables are grounded at both ends, or when the who-knows-how-it-is-wired UPS is involved.
It's a hazard well-known to electronics engineers: The non-obvious ground connection that burns out the input stage on your £600 oscilloscope. It's why they keep an isolation transformer on a little altar next to the workbench and offer up a prayer to it before getting out the probes.
If you're careful you can operate on a drive without a cleanroom. I wouldn't trust the drive after, but it can be done. I've done it - replaced the cover of a drive with a plastic panel so the insides could be seen. It was intended as a working demonstration drive for an IT class.
Exploding li-ion cells are usually due to an internal short. An external fuse wouldn't help. Poor charging practice (over-charging, charging too fast, neglect of temperature monitoring or a mechanical mounting that compresses the cells) causes damage to the insulator inside. Once it shorts even a little the heat produced quickly causes additional damage that quickly leads to thermal runaway and boom.
Humans are terrible at assessing risk. They overestimate risks that involve something spectacular, or that are the work of an active agent, or are so rare as to be highly reported. Exploding batteries are both spectacular and highly reported. They underestimate risks of events for which there is no responsible agent or that happen so often as to be no longer worth reporting upon, like traffic accidents.
My favorate example: In each period of a little over a month, the US loses as many citizens to traffic accidents as it lose in the 9/11 terrorist attack. Yet the country has not declared a 'war on roads,' or spent trillions on road safety investments. Road deaths are boring, no-one cares about them, but people live in fear of terrorist attack - even though they are many times more likely to be hit by a car than bombed by a terrorist.
That used to work. Then manufacturers started struggling to meet consumer demands for ever-thinner phones. When you need to make them no more than a few mm thick or they won't sell, anything that adds thickness must be cut. That includes removable batteries - which require the thickness of plastic each side of the cell and an extra removable back cover on the phone. Consumers may like replacable batteries, but not enough to accept an extra 2mm thickness.
Try looking at the Samsung SM951. It's not quite up to the same performance as the Intel 750, as it's an ACHI device (With promises of an NVMe in the pipeline), but it's still bloody fast. 512GB capacity, and a whole lot cheaper than the HyperX or 750.
If you wait a few months you might be able to get the promised NVMe version of the SM951.
You can provide reliability at a higher level. The btrfs filesystem does almost exactly as you describe: Everything it stores, it stores with checksum. If data it corrupted the check will not match and it will detect the error. If you've set it to provide protection too, it'll have another copy it can use for recovery.
A VR headset can be a good way to shove a great deal of information into a person's perception without needing a bulky multi-monitor setup and in a quite small physical footprint. Just need to get high enough resolution in the panels, and that's a solvable problem. You've potentially got a good interface for those who have to coordinate very-high-information systems. Air traffic control, military command, network operations, real-time social network moderation, industrial control.
Maybe it is a sense of international justice. Or it might be publicity - standing up for a popular individual on the run from the oppressive US makes them look good to a lot of people. Or perhaps he is a bargaining chip for future use - if they ever need a low-level concession during some negotiations with the UK, the US or Sweden, they can offer him up in return.
Time served only counts if in custody, and it doesn't matter: Assange believes the charges are part of a conspiracy, lead by the US, to discredit and imprison him for his role in disseminating classified information. I do not know if this is true, but it does sound plausible and the timing is certainly suspicious. He is concerned that if he went to Sweden for 'questioning' he would arrive to find a string of trumped-up charges sufficient to imprison him for decades, or else a convenient extradition request to the US where he could be disappeared into a secret prison for the rest of his life. He is avoiding trial because he does not believe it would be a fair trial.
The purpose of those names is to be easily readable and learnable to humans. This means some names are going to be more valuable than others, possibly very highly valuable. It also means some are going to be trademarks. This in turn means you need the legal system involved, and so a degree of centralization and administration to allow judgments to be enforced.
There was an Outer Limits episode that addressed the slavery thing. Aliens came to enslave a group of humans, and one of the humans went so far as to point out that this was silly: Any civilization that can build starships has no need of human slaves.
The alien explained it very simply: Their culture considers the use of mechanical labor 'demeaning.' Presumably slaves serve for them as a form of status symbol: Anyone can afford a robot, but having slaves to tend to their needs is the mark of true wealth.
I like the intent of prohibiting export of censorship tools, but what's the point? This is now super-sophisticated code: Any halfway-advanced country could just develop their own. Hell, I could knock up a program for searching for forbidden terms in HTTP requests and sending TCP RST packets like the GFWC does - it wouldn't be as sophisticated or as scaleable as theirs, but it'd work.
Thunderbolt is the new Firewire. It's superior to USB3 in most ways, but it's also insanely expensive - and who cares, when USB is 'good enough?' There is no consumer application that might require more bandwidth than USB3 can provide, so thunderbolt is stuck in the same niche as Firewire once occupied: High-end AV gear and super-fast external drives.
Churches have long doubled as antenna towers. They are usually the tallest building for some distance around, and are already built and connected to power and phone lines. It's cheaper to rent a cupboard at the top of the tower than to construct and cable a purpose-built mast.
Rubbish mines have another advantage: Accessibility. You don't need to dig deep shafts to reach any deposits, landfills are right there on the surface.
I don't know how 'rich' landfills are though. Maybe once in the distant past things were more worth reclaiming - but the waste of today, even the electronic waste, looks pretty poor. Everything is plastic, and the electronics have gone down in volume a lot - you no longer find stacks of circuit boards in most appliances, just one tiny controller. Not much money to be had in that, even if you invented a magical low-cost separation machine.
