I wonder if there are any uses for mechanically modulated retroreflectors today. NASA is investigating fully mechanical rovers for Venus because semiconductors do not work very well at Venusian temperatures while mechanical devices do[0]. To get data back from a fully mechanical device they propose to use retroreflectors. Although the bandwidth they can achieve with their approaches, using semaphore messaging with retroreflectors and looking at the doppler shift provided by spinning disks, is low. Perhaps by using a device like the thing they could transmit data at acoustic rates. I am also curious if there are more down to earth applications for devices like the thing other than espionage.

It was a legitimate question not intended as trolling. The other replies gave exactly the kind of information I was hoping for to clear up my confusion.
Part of me thinks that if Apollo was a good company, they wouldn't need to keep raising this kind of funding by now. There are plenty of alternatives which burned a fraction of what Meteor/Apollo has burned to build this. They're taking funding and attention away from other more deserving projects.
The rule limits Google's proposing are more generous than the limits Apple puts on content blockers. Apple allows only 50K rules. And it turns out 50K rules is actually fine!

Declarative rules engines are better and preserve privacy better. This is Google following Apple's lead and doing the right thing.

Whether we have free will or not makes no real difference as long as we can't prove whether we have it or not. Besides, even defining the term "free will" is difficult. One thing we do know is that we do not have rules and do not enforce them, then we'll get more of the behavior that we have found undesirable enough to have rules against it -- whether this is due to our having free will or not is immaterial to whether or not we should have rules.

I theory yes, but in practice react native development seems to be a grab bag of 3rd party libraries and design patterns. Redux, apollo, some typed objects, some untyped objects, stateful wizard views, stateless normal views. Maybe your objects are defined and queried on the view you are looking at, maybe they came from a previous view.
Thank you so much, we also believe that is the best approach. I wouldn't describe the context of naming the product and why we did it better than you just did :)

Owning slaves was legal and enforced by the law at one point too. Was the underground railroad an immoral drain on society?

While not all of Silk Road was sunshine and rainbows, the changing attitudes towards marijuana legislature is proof that circumventing the law isn't always this drain on society because the law isn't always caught up to society.

Hence the 'death by a thousand cuts'. We couldn't fight every battle. We lost.

So does the future belong to those who can administer the "thousand cuts?" In 2019, that means those who own the Cloud server farms and control the organizations that hire hordes of programmers. Does that mean that privacy is dead by an inexorable process? Doesn't that imply that individual liberty is also, eventually, dead?

How can we, the people, administer the thousand cuts?
> This looks like a good way to spark real-life violence in what is otherwise a remarkably safe way to exchange drugs.

The drug war is the antithetical to harm reduction and safety in production and use. The only solution to the drug war is decriminalization, legalization and improved health systems for harm reduction.

Most of the issue with the drug war and overdoses is in direct relation to drug illegality. Users get badly produced products, mixed with harsher drugs like fentanyl that are cheaper or people can't get them help due to the criminality of the policy. Drugs can be dangerous, the drug war and illegality makes them more dangerous and obliterates harm reduction. The hard line approach leads to more dangerous synthetics that only exist due to the illegality of the substances they are analogs to. Anyone taking drugs that is addicted and needs help, should get help, not felonies and put in a building with violent criminals, adding to problems problems doesn't solve anything.

Not only that, the drug war has diverted funds to mafias/cartels that have built them to the size of nation states, making the whole thing extra violent when it is mostly just a non-violent end result. We learned nothing from alcohol prohibition.

The drug war also makes respecting law and order a joke when drugs like marijuana, LSD, psilocybin and more are treated harshly, these are safe drugs with very low toxicity [1], lower than caffeine, aspirin and nicotine, and keep people from harsher substances.

Ultimately the drug war is a war on people and plants, that is part of a drug dark age we are in, that will look quite silly in retrospect from the future, same way alcohol prohibition looks today.

Alcohol is a drug, it is dangerous, but also fun, as long as there is harm reduction and information about it and it is produced safely. When alcohol was illegal, all of that, including production which led to explosions and production of deadly batches, was more dangerous being illegal than legal. It is also safer with the legal market running it rather than the mafia, the reverse is true in other illegal drugs.

Harm reduction, decriminalization, legalization and bringing a regulated market in will make all substances safer, markets around them efficiently work safety into the system when is has enough market value as there is liability that pushes producers to make safe products and information about harm reduction.

It is time to throw in the towel on the war on people and the human condition, then turn to a human/health/market focused solution rather than authoritarian enforcement solution. End the drug prohibition dark age. We need a Right to Body amendment that ends this prohibition and future attempts.

I hear you. There was a time when I could pretty much describe everything that happened from the time you pressed a key to the time a file was displayed on your screen: exception/interrupt handlers, keyboard driver, network stack, storage stack, context switches, page faults, etc. And that was a pretty good chunk of what I needed to know in order to do many useful things. Now some of those pieces aren't even relevant any more, the others have all become far more complex, and new ones keep being added at an ever increasing pace. Nobody but nobody can know such a high percentage of what's going on as many of us once did. I'm not saying it was better, but I do miss it.
Interesting, thanks. The mechanisms that cause such a delayed temperature response are still opaque though, figure I gotta read more in-depth technical stuff to really understand.
People seem to mistake the UN for what is truely meant to be.
The UN is not some government which can enforce agreements. Its mainly a "meeting room" for global and local powers to resolve conflict if they wish.

At the end of the day, this is still hugely important to prevent unnecessary war or conflict, but the UN is still bound by the actual realities on the ground, not the legal framework that sits above the reality.
He had historians follow him around, so greatness in posterity was clearly important to him. Objectively he inherited the worlds best army and a next door neighbor with an empire hanging by a thread. All he had to do was push. The fact that he gets to own the word “great” owes more to his understanding of history than any inherent greatness.

Whether he was happy or satisfied or suffering imposter syndrome feels like attaching modern sentiment to classical times. Dude murdered people by hand a lot and drank himself to death. I don’t think he was happy or satisfied, and I think he would laugh at the concept of imposter syndrome.
This... doesn't really describe the motivations for IPv6 well.

Working in networking, it was much-beloved because it eased the address allocation problem by giving you an enormous, equally-sized address space for every subnet, and included a potentially-simpler, stripped-down version of DHCP for non-router nodes. (Edge routers usually use DHCPv6, but only to learn what prefixes they should hand out to other nodes.)

For core network administrators, the additional address space lets them organize their routing tables hierarchically, which makes them smaller and easier to optimize for latency.

Plus, while they were breaking compatibility anyway, fixing up a bunch of annoying things with IPv4 that had been bugging implementers forever, like dropping (ugh) fragmentation, rearranging the header information to make it easier to do routing in hardware, and adding support for metadata in the form of extensions (useful for ISPs tagging traffic with routing instructions). Mobile IP was part of this, and was indeed IMO misguided, but is not the only or (in my experience as an implementer) the main motivation.

That whole digression into the semi-mess that is edge networks over the 802 suite (ethernet + wifi) is irrelevant to this core-network motivation. And in any case, ARP is (again, speaking as an implementer) a very tidy and useful abstraction layer. It's even used on non-ethernet networks!

tl;dr the big "killer app" of IPv6 is that it makes the lives of router makers and network-stack coders easier. Writing new IPv6 code is harder than just using your IPv4 code, but for green-field projects IPv6 is so much more pleasant to work with.
Sadly they both appear to have a total board power 50W higher than NVIDIA's comparable model(s), so NVIDIA might still win out on power. But we'll have to wait for third-party benchmarks to confirm that.
The opposition to that, Clipper chip, and V-chip are three of the specific examples that come to mind when I think of cultural changes among CS techies.

My impression is that there used to be more awareness, concern, and forward-looking/vision about such things.

(I even recall techies being shunned for doing the tiniest fraction of invasiveness/recklessness that some major companies do today, yet those companies are now regarded as prestigious places for techies to work.)

These drug markets are open to the entire internet and the customers and suppliers are global. The fact that US officials consider this their jurisdiction is troubling to say the least.

I dont think this is a valid argument: muscle memory is extremely contextual. Your muscle memory for your phone is definitely different from your laptop, and I don’t think the context switch is actually a hindrance.

At least when I tried it a few years ago, the Windows client was also a crappy Python app that ate CPU and disk for around an hour after every startup.

Why? To detect changes, they were storing a snapshot and comparing everything on disk to the snapshot. Which is madness when Windows has methods that don't require reading every damn byte on the disk - at the least, they could use a filesystem minifilter driver, or the NTFS USN change journal.

As if that wasn't enough, after the startup scan they were using an unreliable method to detect further changes (same one as dotnet's FileSystemWatcher, I forget the name of the underlying Windows API).

And to top it all off, even with only 2 systems sharing the data, there were conflicts all the time that required manual resolution (and I seem to recall Dropbox wasn't very good about surfacing these when they happened). Then there was a data loss incident, I presume due to some kind of conflict snafu - Dropbox only support at the time was a forum, and they were completely uninterested in even acknowledging that there was an issue.

I switched to Seafile after that, and haven't looked back. I honestly don't understand why people would put up with that crap, but given the size of Dropbox they obviously do...
So how come when you first join FB it starts suggesting people to befriend who you already know? The only way to do that is by collecting information in the background for every living being. They aggregate everything and then they make correlations. By the time you decide to join they have a pretty good idea about people you might know. I can't see any other way for something like that to work.
The primary reason we care about Saudi is oil. US policy makers seem to view them as a necessary evil until we transition to renewable energy. No real effort is made to influence reforms. In fact, the more culturally isolated Saudi is from Europe and other countries, the better it is for the US, in terms of dependency.

At some point after “peak oil” SA seems likely to experience extreme social upheaval - perhaps even revolution or civil war. One hopes that this could serve as a catalyst to build a more tolerant and inclusive society.

I agree, but I should also note that many of the recent analyses I've published were on systems which wrote their own tests and missed significant errors. Like, "database loses updates frequently in normal operation" significant!

I think a bunch of factors are in play here. Sometimes vendors discover bugs with Jepsen, then adjust the test so that it passes, rather than fixing the underlying bug. Consul, IIRC, found errors with Jepsen, and adjusted a timeout parameter to prevent the test from observing concurrent primary nodes, which meant the test passed. The underlying problem was still there--but no longer visible. Sometimes you'll see people turn a workload that does a read-modify-write transaction into a single-statement update transaction, in such a way that the database can execute it atomically. That's still a legal and sensible test, but may not measure the same type of transactional isolation.

Other times, vendors write a custom checker, but haven't tested to make sure that it can catch the anomaly that it's supposed to. Maybe a checker is copy-pasted from another test I wrote for a different system which used different names or data structures to represent histories, so it executes successfully, but in a trivial way--maybe it fails to realize any elements were added to a set, so it assumes every read is legal, since all 0 elements are present!

Other times tests are correctly written, but only run for a short time--maybe the nemesis schedule they designed doesn't actually cause leader elections to take place, so you never observe that phase change in the system. Or the test only performs a handful of operations and sits idle until the end of the test. Or every request fails, and the test passes trivially, since we never observed an illegal result. Some of these mistakes I can address with better analyzers and prompting users with guided error messages. Others you have to qualitatively infer by looking at the graphs and histories. That's something I work on training people to do in my classes, but I haven't written good guides for it online yet.

And of course, there's a familiarity problem: with Jepsen, I've been working on and with this tool for six years, so I'm intimately familiar with its behavior and testing philosophy. So much of that knowledge is implicit and intuitionistic for me, and users who are adopting that tool fresh don't have the benefit of that experience! It's something you can build with time, and I can help transfer with writing and teaching. Working on it! :)

A security clearance requires that the government know more about you than just the background-level life events of yours that they passively subscribe to.

All they need to know for a plain-old no-clearance public-servant position is that you're not beholden to a foreign power (e.g. part of a foreign gang, or in debt to a major foreign corporation.)

There's an easy (though imperfect) heuristic for determining whether you're potentially beholden to a foreign power, from the data they already have: the addresses you've lived at, your job history, and your arrest record. Just join that set to the set of organizations they're tracking as catspaws for foreign powers [and their active locations], count the joined rows, and you have a log-probability that you've ever had the opportunity to interact with someone who might have had cause to convince you to work for a foreign power.
Assuming you're correct, there's plenty of useful stuff they could do with the extra money. Further development of Rust, revive Thunderbird, support web tech, come up with something that makes Google's AMP irrelevant.

In the wake of a slew of fatal accidents involving elderly drivers, the government plans to create a new driver’s license system that limits senior citizens to cars with safety features such as automatic brakes.

This seems like a feel good story for the papers and a way to further penalize drivers who don't have the proper car for their license, but I wonder how this works in practice to actually prevent accidents, given the parameters of what's being reported. On your 75th birthday, do they repossess your current car and make you buy a new one?

Otherwise, there are still going to be a lot of dangerous autos on the road.

We really love Apollo and use its open-source software in our GraphQL stack.

With that being said, I really hope Apollo will provide their iOS library some much needed love soon, or clearly imply they're not developing it anymore. They've mentioned they're hiring an iOS engineer maybe a year ago? but largely the repo has gone neglected. I've made some modest improvements for our sake, but PRs generally go unreviewed forever, so it doesn't seem worth writing the tests to get my work in a landable state.
See my comments to other replies. The simplest description of the justice system upon society is constructing deterrents for actions decided as bad. The argument that people need to believe in free will to be good people hasn't been proven fundamentally true. The deterrents made by the justice system don't work for everyone and it's not fair when people have events or the genetics making the deterrents not work for them like others. I'm not voicing for no rules. I'm suggesting a better system needs to be designed.

I would say striking up conversations is possible in EE and US (and everywhere else?) to about the same extent, but just like language, social norms, attitudes, social clues can subtly differ in various places, and a strategy that works in one place may not work in the other, as you say the American style may come across in some societies as a bit aggressive.

You are missing the point, it isn't that simple. Doing the opposite might keep cities cleaner or reduce crime but the cost is significantly higher to maintain. A prison population is a social service that is incredibly expensive, the more enforcement there is, the more expensive it is per body. This doesn't solve the problem it just costs the taxpayer more for another non-solution.
