> While the 2016 election mythologized the power of these influence-actors, such work is slow, costly, and labor-intensive. Humans must manually create and manage accounts, hand-write posts and comments, and spend countless hours reading content online to signal-boost particular narratives. However, recent advances in artificial intelligence (AI) may soon enable the automation of much of this work, massively amplifying the disruptive potential of online influence operations.

All I disagree with is that it's already semi-automated, has been for some time.

A long time ago, I saw a tech support person with a spreadsheet full of formulaic responses for common issues. "We're sorry you're having trouble with _x_ , dear _y_, have you tried _z_. Please accept a $10 discount voucher for your trouble. Thanks, Bobby Techops" kind of thing.

It has progressed, I'm sure. Why wouldn't it? And will progress more.

And the large actors have no incentive to tell everyone how far they have got. The opposite, in fact, they will try to hide it, e.g. Cambridge Analytica being dragged kicking and screaming into the light.

And a small army of clever educated young people isn't that expensive to a large corporate or state actor. Call Centers depend on it.

Greeks use Chinese as the canonical example of an incomprehensible language.

What's interesting is that although the "It's Greek to me" colloquialism mostly refers to the fact that the Greek alphabet seems incomprehensible to the (non-classical-humanities-educated) reader, Greek has actually a very complex grammar: Everything is conjugated, everything has genders, and you have to remember the correct form of every noun, preposition, article, pronoun, etc. In comparison, Chinese grammars are amazingly simple.

Most Greeks don't take notice of this fact until they see somebody struggling to learn Greek as a foreign language.

A Google engineer would have no incentives to kill Firefox unless he can convince a promo committee that killing Firefox is good for Google, so I am not sure why anyone would do it. I mean, do you think someone would put "Slowed down Firefox gmail page load by 50%." on their promo packet?

So for it to be done in secret for many years you would need someone with enough clout to circumvent the promo process behind it. I am not sure how high up you need to be to do that, or if it is even possible to do for engineers.

Instead if you take the promo driven perspective, it is a lot easier to make things work well in a single browser. So the engineer makes a site twice as faster in Chrome, writes "Made the site twice as fast" in their promo packet and gets promoted. No need to mention that Firefox performance got worse after the fix, the promo committee wont have time to check that.
No, it's not full implementation. The main difference between this and Zalewski implementation is using direct mapping data between kernel space and userspace. Zalewski implementation uses pcap for capturing packets. If you have huge workloads you can try this https://gist.github.com/xpahos/4bc215aa5fe237161bc076f247643... to try multithreaded capturing packets(https://github.com/the-tcpdump-group/libpcap/pull/674).

My implementation creates a hash map between kernel space and userspace where eBPF(kernel space, directly from sk_buff) code stores parsed data in this map. After accepting a connection in userspace application could check this hash map and get data from kernel space to userspace. So it's possible to add p0f extra data to request headers directly inside load balancer/web server and pass it to underlying levels.

No, doesn't look like. Halbach arrays use magnets in different directions to smoothly redirect a field; you can do the same thing with iron or soft steel. Since the field on the back side of the magnets is basically static it doesnt cost any efficiency and its much cheaper. Halbach arrays are sometimes used in motors that need to be very light, like very specialty high-acceleration brushless motors.
I thought the uber vc-backed business plan was to expoilt their drivers until they can be replaced by homegrown autonomous vehicles- if this is true they have a huge engineering problem to solve.

There are quite some parallels here with the Theranos story. Both seem to come from a place of ignorance mixed with unearned self belief and exceptionalism.

The reason you're getting downvoted is it seems like you believe encryption should be illegal unless it has a govt backdoor. Encryption is just math, so it's a hard thing to criminalize and to enforce. Furthermore, if the government has a backdoor to all encrypted data then that means China and Russia and any independent hacker would be also searching for that same backdoor and once they find it everyone's screwed. It's really impractical to think that the government could enforce backdoors into all encryption and it'd be exceptionally dangerous if they required all US companies to comply with backdoored encryption. Not to mention the privacy implications of never being safe from government surveillance.

As someone who’s helped on both the technical and hiring side of a company that’s scaling, I agree and will add that a lot of hires are made in order to make life easier for existing hires. A team completely composed of 1:1 developer to team/role need is one vacation, child birth, or illness away from unnecessary added stress. From a purely technical side of things we crib it as “bus factor” and try to negate that with documentation and knowledge sharing.

A great way to disillusion your management hierarchy (flat or otherwise) is to have them constantly juggle supporting their reports’ needs and the business asks when functionally understaffed all year. Having some “extra” headcount while remaining ROI positive is good for the humans even if it doesn’t make 100% accounting sense.

It’s also a good way to make space for deep work and interesting innovations you get by having the luxury of unlimited ping pong time... Er I mean water cooler chats.

Don't discount the googling that easily. Doctors everywhere will Google both procedures and symptoms. (and check procedures on YouTube!)

It's succeeding brilliantly. The purpose of automation is not, and has never been, to free people from work to pursue lives of leisure and intellectual stimulation. Its purpose is to concentrate the wealth created from labor into the hands of the ownership class without having to lose any of that wealth through hiring and compensating a human workforce.

When the number of jobs available to the labor pool is reduced by automation, the market value of human labor goes down, but the amount of work humans are required to do to survive remains the same, or often it increases to take advantage of the efficiencies create by automation. Obviously, people will tend to wind up either unemployed, because there are fewer jobs, or working harder for less money, because their time is worth less.

This isn't a failure of the system, this is the system working as intended.

If you want to get fancy, you can call it the Taylor approximation.

I'm a bit lazy so I try to use the F(c)= 2 * c + 32 approximation described in a sibling comment, but for the range of human-friendly temperatures the error is too big. The problem is not the absolute difference, but how each temperature feels. So I have to resort to making the exact calculation or using Google for the conversion. I'll try your method in the future.
Mass surveillance is unreasonable search. Court-ordered passphrase disclosures are compelled speech and forced self-incrimination. Equipment is seized from innocent people willy-nilly.

The "right to privacy" refers to a bundle of other rights the state is already spitting all over in direct and obvious violation of the Constitution, and our judiciary is wasting the blood of our great nation's many dead martyrs.

That said, I believe privacy is such a lost cause at this point rayiner might still be arguing effectively for our remaining rights by throwing it to the dogs while they're sniffing for our guns.

> Going from 80% to 90% means that you need half as much

> cooling

At the very most this will be < 5% performance increase because they'll need to match the best of BLDC (~90%) and 100% is simply impossible as there are losses that cannot be engineered out (thanks Physics). Also that 80% -> 90% isn't all heat, I imagine the amount of cooling required to stay roughly the same.

> batteries may be more efficient when you draw less power

> from them, etc.

From memory, a switch mode power supply is one of the most efficient at about 90% - but you really have to design it well to get that kind of efficiency [1]. The batteries were a soft point for cars. But there's quite a bit of efficiency to get from phase control algorithms which would be in the motor control circuit.

Meanwhile, I logically built on the same point to present a contrarian opinion, so your initial reply is somewhat pointless nitpicking. It's exactly what the author of the article intended, making a passing reference to the fundamental flaw thet invalidates the rest of the hype contained.

A Japanese friend told me, Chinese is as easy as English. But characters are easy for him. For us Chinese is hard to speak because of the tones. The grammar seems very simple, simpler than any European language. Japanese has no tones so it's easier to speak. Reading and writing, both are a mnemonic nightmare. I remember European kids don't like multiplication tables, lol.
I would characterize the home invaders as the "perpetrators" in that particular story and exclude them from the injury count, consistent with the language of that definition.

From the article: Gun Violence Archive, a nonprofit research group that tracks shootings and their characteristics in the United States, defines a mass shooting as an incident in which four or more people, excluding the perpetrators, are shot in one location at roughly the same time.

This idea works very well, as long as it is applied to a tiny group of people who know each other well (one family). With larger groups it doesn't work at all because of game theory. The people who work hard to build better "means of production" or use them more effectively, as a reward get all of their work seized by people who do not want or know how to use these "means of production". As a result the production goes down and the quality of life of the people goes down too. If you allow people to leave your country the best workers leave it, dragging the quality of live of the remaining people too, if you want to not allow that you have to build a police state, and the quality of life becomes even worse. This is a simple theory, which have been tested multiple times, and sadly in my country too, and i hope the next time this idea gets tested it is tested on people who wilfully join the test and have the ability to leave it.

> Ironically, in that one instance where this woman put a child in a critical condition, she might have saved it, because now the hospital would take it in, where it would have been refused before.

This is accidental. I'm not going to go around stabbing people just in case someone looks at them in the ER and notices an early melanoma. But you could write a comparable "ironically" if it worked.

The kid could recover without intervention, could die immediately, could recover in the hospital, could die in the hospital. We can't just count on lucky harm in cases like this.

> I just want to mention that improving motor efficiency would also help with some of the other losses you mention.

It's not that simple. Increases in torque are strongly associated with increases in current- torque is directly proportional to total magnetic flux, so more torque in a smaller package generally means more current in your wires. The alternative is to add more turns of thinner wire, but thinner wire has lower packing efficiency.

Losses from current rise as RI^2 in simple wires, slightly faster in transistors, and some very complex factor in batteries that I can't remember but is between I^3 and I^4. You can make a 100% efficient motor, but if it quadruples the current draw then it will be almost useless for vehicles.

The greatest feature of Lisp is that everything is an expression. Almost everything else is secondary as it’s already present in other modern languages.

If you ever encountered a syntactic limitation in any language, you could go to Lisp and work your way around it either with macros or even simple control flow.

I would recommend to skim through Peter Norvig’s PAIP to get a taste of it. Then, as another user suggested, writing your own pattern matching library would be a great exercise.
Very interesting, thank you! Do you have more information I can read about phase weakening and BLDC control algorithms?

I ask because I happen to be designing a BLDC motor controller, I am aware of using the back EMF to measure the motor phase, but never considered it as a force slowing the motor down. As a software engineer by trade I was hoping I could perhaps dynamically switch between the two control techniques to get low-end torque and high-end speed? I was also hoping to setup the controller to optimize the various parameters for the specific motor it is controlling by measuring the back EMF.

Any help is greatly appreciated :)
