Doesn't it strike you as odd to suggest that society was built for "white" males when such classification, as a meaningful indicator, didn't even exist until extremely recently? Irish, German, Italian, and many more are all groups today you'd just often just refer to as "white males." In times past? People who were very much second class citizens. And it went well beyond just national origin. Protestant vs Catholic was a huge deal and this also persisted until extremely recently. For instance something lost to history is how monumental JFK's election was because of the fact that he was a Catholic - the Obama of his time. Incidentally the first and last Catholic elected, even though more than 20% of America is Catholic.

Even when you get into things like slavery, Africans were not enslaved because they were black. Slavery was global and of course always began as in group - whites enslaving whites, browns enslaving browns, blacks enslaving blacks, etc. The big reason that "white" on "white" slavery ended was because of a shared religion and Christian church declaring it illegal for any Christian to enslave another Christian (in times before the schisms, such as 'Christian' was reasonably encompassing). The "problem" this posed for those seeking slaves is that tremendous empires were starting to form around the world.

For instance in the ~18th century you're looking at the Qing dynasty in China, the Mughal Empire in South Asia, the Ottoman empire in the Mideast, etc.. The world was rapidly unifying under incredibly powerful empires who were more than capable of protecting their borders and people. But Africa was a major exception. It not only lacked both meaningful unification and technology, but also had a thriving domestic slave trade. This made them a prime target. It had nothing to do with the color of their skin. Had Africans happened to have had a bit less melanin, but the situation remained otherwise identical, it's extremely improbable that things would have changed in any way whatsoever.
All QM interpretations require interference. This is demonstrated by the two-slit experiment (for example). In this experiment, an electron passing through the two-slit shield generates an interference pattern. But if you detect which slit the electron passes through, you destroy the pattern. Why?

In textbook/Copenhagen interpretation, we say that when the electron passes through the slits the wavefunction has not yet been measured. But with the detector in place, you collapse the wavefunction to an eigenvector of position. By the uncertainty principle, the momentum uncertainty is now very high, so the electron shoots off in a random direction and cannot be expected to follow any pattern.

In MWI, we start with the interference pattern. But adding the detector does not "collapse" anything - instead it introduces lots of degrees of freedom. The particle passes through both the left and right slits, but the degrees of freedom ensure there is no fixed relative phase delta between these possibilities. The detector turns waves into "static noise", and so any interference pattern is lost. Both options are realized, but cannot detect the other possibility: distinct Worlds.

The key point is that MWI has no special role for measurement. The left-slit and right-slit worlds interfere, but with the detector in place the pattern is destroyed: the interference is uncoordinated and averages to zero, so undetectable. Whereas in textbook/Cophenhagen QM we say that the measurement results in a single outcome.

I still have my first iPhone, a 3G with the curved back. Every once in a while I pick it up and always marvel at how comfortable it is in my hand compared to the iPhone X I use now. I oouldn't possibly go back to using a screen that small but would definitely give up some screen size to regain a bit of that old "nice to hold" feel.

Interesting idea. Am I signing up on behalf of someone else and creating some sort of account for them? It might be good to show what the experience will be like for the recipient with a video. If a technically challenged person expected to sign up for their own account I don’t think it’s intuitive enough; I wouldn’t send someone to the homepage to navigate on their own.

Having libc updated multiple times per month sounds like a fucking nightmare to me. What am I missing about this situation?
Yeah requirements were woefully incomplete, testing insufficient and may I add design where one unreliable sensor was wired to one processor which was given great authority over a system to wind in one direction very fast and where manual reversing out of was very slow or impossible when speeds got high (improbable when pitch directs you down).

How could anyone believe this system was safe? No testing or requirements needed.
Russia’s Playbook for Disrupting Democracy
There's no "original idea" here. It's an obvious idea I presumed most people have had. At least I have and I haven't seen any of these before so I don't see why he couldn't have made this independently of 3dchan.
I'm thoroughly confused by your comment. Was not Apple's FaceID a full year, if not more, ahead of the competition? Sure they didn't sit in cupertino, stitching together components, but they designed an integration of existing components in a way that saved space and made them work in concert in a way no other competitor had. I don't think they're in as much trouble as you make out
I don't even have a strong objection to Duo or their offerings. If they can make a buck by automating stuff or reducing friction, that's fine. The only part I hate is the artificial end-user lock in. If they just called it HOTP and let the users use whatever client they want, that would be ok. Instead, they have this artificial wrapper around HOTP and make people use their app.
Leading on the job: advice for new leaders in VC/PE backed businesses

Sure, if it were used for the benefit of the public, rather than the benefit of Google.
The best part is that the hospital can bring in an out-of-network doctor or nurse after you've passed out from anesthesia... Without asking you if you were cool with this, before you undertake the procedure.

That's one way to discover a giant out-of-network bill, when you went in for surgery at an in-network hospital, performed by an in-network surgeon, with an in-network anesthesiologist... And an out-of-network nurse, whose job consists of holding the saline bag for 30 minutes, at ten times the billed-to-patient rate of anyone else in the operating room.

I wish I was kidding.
These "gig" companies are all unprofitable. Their current business models are consumer-friendly as they try to capture market share, so people mostly love them. But they are not sustainable, the prices will eventually have to go up or become a worse deal in some other way. They are just hoping to use all that cash to stumble into some kind of monopoly or lock-in that eventually removes customer choice. They are not good for society overall, we might get a lot of cheap convenient transportation in the short term but eventually we'll all be worse off as they kill off competition. It's basically price dumping, and the sooner they are stopped the better.
Oh, hi Microsoft.

30 hours is the threshold for “full time” worker if you’re determining eligibility for health insurance. No way Uber will offer health insurance to drivers, so guessing hours would be capped at 30 max per week.

I would think the exact opposite...in this scenario drivers who do this part time anyway are fine but anyone driving more than 30 hours a week will be hosed.

Hey you're still at an order of magnitude fewer layoffs than Sprint ION after they blew off a $2B loss in the early 00s. Maybe get your leadership to look at that case study.
Answer is yes, definitely genetic. I have narcolepsy and need no more than 5 hours sleep a night. That has been proven consistently over the 28 years of my working life.

I aim for 5 hours' sleep, though usually it's more like 4h45m. I am less sharp once it falls below 4h30m. I usually work in the evenings til 12:30 or 1am. I wake up around 5:20am, usually just before my alarm. I cycle to work and arrive at the office shortly after 6am.

Narcolepsy is usually associated with daytime sleepiness. It is best described as a switch in my brain that turns off if I don't get enough stimulation. I was prescribed drugs for it (dexamphetamine originally, now modafinil) but I don't take them anymore. I prefer to treat it by having very high-pressure jobs (currently Chief Risk Officer for a start up, previously tech lead for an investment bank trading desk). Also I have found that computer programming provides the perfect amount of deep mental focus to beat narcolepsy.

At night, narcolepsy means I fall asleep instantly. I hit the REM sleep phase within a couple of minutes. Most people need 90 minutes to reach REM sleep. So that alone means 4h30m of my sleep is equivalent to 6 hours for a 'normal' person.

(Final note: This was verified clinically by an overnight stay in a sleep lab then daytime sleepiness tests the following day.)

What this means: much more expensive Uber/Lyft rides which in turn means fewer riders, and thus, fewer drivers out on the road and longer wait times.

The labor market is a complicated thing, much more complicated than just supply and demand. But these types of controls are often not the right tool for the problem.
At face value this proposal makes no sense because it means that the total voting rights are less than 100%...
40-50 milliseconds is correct in terms of latency that musicians notice.

In a 60fps app that's as much as 5 frames out of sync. Users would notice that.

Another candidate for covfefe?
We've just spent a good half hour or so trying this out.

It has a snappy interface but in some respects it's very heavy - ie in the number of clicks needed to do anything.

The main one for us is estimating. We want to be able to go through a list of stories and edit the estimates. The fact that the table of stories isn't editable means we have to open up the dialog for each story to edit the estimate.

As a comparison, we're currently using Airtable for some projects and Notion for others. In both of those, you can do that.

Also the ability to add our own fields to stories is something we use quite a bit.

Otherwise it's pretty nice.
It actually sounds like they've already been analyzing all links, regardless of "nofollow". Which is not surprising in any way.

You're buying into the stereotypical myth that social media is always like this, a glamourised facade. My social media feed is anything but positive. People are very real about their problems.

Just the other day I read an article that being open about your issues is the new hotness on social media. I would even say it's the other way around now. People fake problems in order to get followers.

Thanks for your input. I've never been really satisfied with the level of interaction of messengers. They usually end up as a firehose of short messages, where everything meaningful and important is lost in the noise. It's good for quick notifications, for sure.

What I'm imagining, for the types of things that I like to do with friends and family, is more oriented around long term social interactions. This means being able to plan and view events, view and split payments, and build a persistent group album -- to start. When I'm sharing videos, music, or recommendations, I don't want it to get lost as soon as it reaches the top of the screen.

This is where messaging falls short and I believe it can be supplemented by a lot of the features of traditional social networks.
Safe to say this is way out of technical capabilities of the average (power) user; but kudos for documenting the process nevertheless! Maybe someone in a local hackerspace would help out...
No it didn't. When it was legal, most inhabitants of the U.S. had no personal experience with slavery. It was critical to agriculture in the Southern states, but the North was the industrial powerhouse. And the states that constituted the North continue to be the most dominant region in the U.S. to this day.
Does anyone know how this will effect Google contractors?

It's far more likely that Socrates operated with a psychology that would be recognizable to modern man (inasmuch as human psychology can differ wildly across societies and eras) than it is that Julian Jaynes's theory of bicameralism was anywhere close to correct.
If it wasn't for iMessage, I wouldn't even be using an iPhone...
You then pay somewhere around 175 to 260 usd per year for your phone. The newest iPhones are about $1000. From my experience, and from others, they last a very long time, and a 4 year cycle can be expected, as well as passing the phones on to their kids and so on. There is also the possibility to sell it used down the line, and the iPhones keep their value much better than any Android phone.

Thus the "expensive" iPhones are $250 or less per year. And they are, in my opinion, usually better than the Android equivalent.

You might say; "but what if I have the same upgrade cycle with iPhones". Well, then you can have a look at what a used version of the last gen iPhone costs. Where I live; it is something like $100-200 less than what it was new. That means; some people are having the newest version of the iPhone for only $100-200 / year. That is, at least, roughly the same price as your are getting (or better, depending on resale value of the specific Android phone), but with the newest version of a more premium product.

In other words. You might be getting ripped off at $260. It all comes down to money over time, not amount at a defined moment, unless the amount is prohibitive.

I never understood the need to protect a certain class of non-innovative noncompetitive services like banks and telecoms. It just a way to make a few a*holes rich.
If it were free, I'd be pretty tempted to use it, and hope somebody would notice my protest. Duo is thrust upon me by my university. I don't want to install Duo's proprietary app for receiving pushes or generating codes (I effectively can't anyway because my phone is de-Googled), and getting cell reception to receive their call can be difficult in some buildings. The other day it took three calls until the system detected my DTMF press, maybe because I was sitting next to a loud fan.

I dabbled at reversing their Android app, but I saw some references to key rotation and got disheartened -- I don't want to spend man-weeks on this. I was hoping to see some URL I could hit and just get a TOTP secret.

To my uni's credit, they offer support for hardware tokens, and maybe someday I'll get sick enough of the phone calls to start carrying one of those around.

Edit: Thanks to commenters in sibling threads with possible solutions to extracting the secret.
The funny thing is that the incumbents have largely enjoyed the monopoly and “lock-in” you described because their position was legislated. Services like Lyft and Uber were just so much better they couldn’t be stopped. Now this is just an attempt to legislate back the status quo.
As usual, infinity complicates things; the series has pointwise convergence but not uniform convergence in such cases.
I can see who you are from your name. I wish you have a good time on the coming National Day, since it is the last one for you evils.
They're calling that "Remaking the Gig Economy"? Making Uber and Lyft drivers into employees? What a sham.

For 10 years I ran my own consultancy. Every new engagement was a new "job" where I could negotiate the rules of engagement however I deemed fit. Usually lasting no more than 5 days each. Every new month for 10 years I'd think: "this is it, it's over; I have no work scheduled for next month, I'm going to have to give up and get a real job." But somehow the work always rolled in, and I did really well. By the end I was billing over $300/hr, and I worked when and where I saw fit. As far as "gig workers" go, I was about as successful as you can possibly be.

And yet my wife had to work a Real Job at a Real Company because I couldn't buy reasonable health insurance for any price. Any price at all. So I spun down my company and got a real job. The Gig Economy is an utter poopshow; not even at the very top is it sustainable.

Making Uber's bottom-of-the-barrel jobs slightly less abysmal doesn't do crap for the Gig Economy. Driving for Uber isn't a Gig. You're not negotiating your rate on each pickup. It's a carefully managed relationship with the same company each time, who pays for your service on a recurring and predictable fee-for-work basis. It's a job.

Fixing the Gig Economy means making it possible for people to make a living without the shelter of an employer. And making Uber and Lift into real employers doesn't fix it. It's not even related.
I believe it means volatility of covfefe.
You need 4 things to run a company, in small companies some roles may overlap. In no particular order Workers, customers, management and shareholders/capital. When one gets too much power the company goes rotten. Usually but not always, it’s management.

Funny that, as a Swahili speaker, i wouldn't be able to say this publicly. This is the word for vagina and reminds me of the Japanese city Kumamoto which would roughly translate as hot vagina. But, good luck, the name shouldn't change anything.
The words "many worlds" is misleading to a lot of people. As Carroll says, when a "measurement" occurs, nothing special happens. It is just normal quantum mechanics.

I think in general people accept that there can be a wave function for a cat with the states alive and dead. Cats are much more complicated than that. Presumably they have memory and inside that memory can be things like perhaps the result of a electron spin meansurement experiment. One state of the wavefunction of the cat might have the memory that the electron result was spin up. Another state of the cat might have the memory that the electron result was spin down.

This scenario above is a cat watching a electron spin measurement. Afterwards, the electron does not collapse into a single state upon being observed. Instead, it is still in two states but it is correlated with the memory of the cat (or entangled with the cat).

The belief, at least as I see it and I assume others believe this too, is that the cat has a conscienceness for each state of the wave function. So there is a "conscienceness" or "cat" that thinks the electron was measured as spin up. And then there is another that thinks that electron was measured as spin down. This is where the term many worlds comes from, the fact that there are two "consciences" (well, many consciences). I can see why people would think that part is weird. But how else should it work?

I guess it all comes down to what is the experience of a person (or cat) having a wave function and being in multiple state at the same time (just like all other objects in quantum mechanics). We are not external observers to the world, we are a part of it and we have a wave function too. Or, it would be more correct to say we are a part of the wave function of the system. There is not a separate wave function for each thing. There is just one wave function.

HN is a form of social media, though: users submit content, comment on content and each other, and can upvote content and comments.
Killing Uber and Lyft outright means bringing back the taxi industry, which isn't better for anyone except the cab companies. The biggest benefit of ride sharing for me isn't that it's cheap: it's that I don't have to awkwardly assert my legal right to use a credit card every single time I ride. I'm fine with paying more to ensure drivers are earning a living wage.

Practical Signal Processing by Owen might be a lead worth looking into. It was recommended by Ossmann in his HackRF tutorial videos (he created the HackRF).

It's gonna fall near the extreme end of succinctness.

I had since purchased the book but haven't gone more than a couple chapters deep. It definitely looks like it allows you to dive into the meat of DSP. Don't know if it will fit the bill for rigorous.

I appreciate the coverage here on HN and admit to a lot of personal frustration at how to respond or try to help. I have started a journal to plan ways to get involved and hope to send even a tiny bit of assistance from my relatively comfortable zone far away from the affected.
A much better title would be "Electric eel found to be three distinct species"

https://en.wikipedia.org/wiki/Electric_eel

3 more crazy electric eel facts [0] you may not have known, I didn't:

- "Electric eels are also capable of controlling their prey's nervous systems with their electrical abilities; by controlling their victim's nervous system and muscles via electrical pulses, they can keep prey from escaping or force it to move so they can locate its position."

- "They can also concentrate the discharge by curling up and making contact at two points along its body."

- "When agitated, they can produce these intermittent electric shocks over at least an hour without tiring."
