Cryptography in undergrad was a course like that at my school. Here is the most basic understanding of group theory we can possibly get away with, here is how it applies to RSA. Next lecture now we're moving on to elliptical curves....

Perhaps some topics are simply too big to really teach effectively through lectures. You need to go digging on your own to understand all the myriad details, and put in the hours alone with a textbook.
Yep, the same was true in Beijing. Rusty water was common after a stoppage, even in new developments.
So is this effectively "combat extremism for us and we'll give you a free pass on all that tax you've been dodging".

I'd rather they just paid the tax.
I don’t fully understand the code but this appears to be a very brute force way of doing it, which slows down as you add more raindrops, pixels, and lights.

I suspect you could do the same with signed distance fields in a way that runs in constant time irrespective of the number of drops at least.

You could also then scale and distort the car lights and add as many as you like without affecting performance either.

So cringe-worthy. I drink lots of "raw" water on camping trips, and the only difference I've noticed is a bout of giardia (easily treated, but highly unpleasant). Bottled water in general is an insult to the environment and human progress; bottled "raw" water is all that plus forehead-smackingly dumb. The fact that potable water is almost free is a triumph to be celebrated.

I should have mentioned, the police cordoned off the entire block with tape and there were armed police on every street. The police were also yelling through the megaphone. Nobody was on the street and nobody was leaving their houses in that climate. The parking lot was 99% empty.

As mentioned, he shot the ground directly in front of himself. Once.

And as mentioned elsewhere here, German police would in that case shoot e.g. a leg to disable the threat, not aim to kill. Someone gave the kill order and a lot of shots were fired. Of course your suggestion to use a sleeping dart (or something similar) would be ideal.

On top of all that but less relevant to this thread, they left the body uncovered on the street until late in the afternoon, approx. 8 hours. I took a lot of pictures of the entire thing (starting after the shooting, because I was afraid the police might think I had a gun too with my huge black camera with telephoto lens).
Ask HN: Writing parsers that run in multiple languages
I wrote a sort of natural language parser for electronic component descriptions [1] and am interested in porting it to multiple languages. I have a way to port it to Python but the solution involves translating JS to Python using Js2Py which is quite ugly and probably a bit brittle.

I want to re-implement it, and define the grammar in EBNF (or similar) but have it run in multiple languages. I am especially interested in JS, Python, Go and Java but as many languages as possible would be good. Is there a parser generator that can do that?

haha, Scott Adams cracks me up. Adams blogged about persuasions and writing techniques for years. I learned a lot from reading those posts.

Then he uses the same techniques to promote Trump. Which is fine. People can support whichever candidate. But Adams adamantly denied his support.
Economics is a science where the researchers often assume how the world works as opposed to measure how things works in reality. Economics is sometimes dressed up with mathematics but it is still a soft science.

In other sciences such as mathematics and physics you have to prove how things works. You cannot just make up an arbitrary model and say this is how we think it works.

Consumer credit is created by keynesian now abundant that is owned by richest percent. Thus many the middle class are now debt slaves to the rich percent. This also goes for house pricing which is what caused the last economic crisis.

Keysnian economics does not take into account that printing new money, the new money does not directly go into salary inflation, it goes to factory automation. Factory automation decreases the price of goods and are thus deflationary. Software is also automation which again will have a deflationary force. One robot replaces on average 5.7 humans.

To sum it up Keysanism make the richest one percent richer and most everyone else poorer. The way Keysnaism does this is by central banks printing new debt out of nothing that the richest percentage then owns. Whats the next bubble Keynesian economics is going to create trillions of Hedge funds that may burst or subprime auto loans?

Hackathon Report: What can you code in 30 hours? Quite a lot
This piece is interesting but it misses the elephant in the room: Work is transactional at its heart. When somebody is your boss and you depend on them to pay your bills and feed your family then they are not your friend no matter how pleasant your interactions may be. This is why people work so hard to protect themselves. You ultimately can't ask people to be vulnerable and honest about their true opinions without some kind of consideration to offset the risk. This is why tenure is so coveted in academia.

The nice thing about this sort of accusation of projection is that you can use it literally any time you want to terminate a conversation! For example, I suspect that your suspecting that Scott Adams is projecting is projection on your part. Checkmate!

I'm half joking, btw. So no offense intended.
Intrigued by this I visited https://www.shadertoy.com/. There does seem to be a thriving community there.

Problem is, the browse pages have a 4x3 grid of live WebGL previews (rather than e.g. static images) of the shadertoys.

On my home desktop pc (win10, i4790k@4Ghz, GTX1070, 24 GB) running Chrome this means that inevitably, on page one or two, at least one of the shadertoys will use so much GPU computation that it starves out all other functionality, like being able to switch tabs etc.
When I was in elementary school we lived out in an area dominated by rural farmland. I'm guessing close to 100% of the students at the school got their water at home from an untreated well. Once a month the school nurse would bring around little cups of fluoride mouth wash and we would swish with it for 3 minutes then spit it out.

If you are seriously concerned about fluoridated vs non-fluoridated water there is no reason that the two things have to be linked. Heck, you can get many mouth washes with fluorine in thing. Listerine has a fluoridated version for example.

They don’t call them UK teeth for nothing. It obviously does have an effect on tooth decay, I’ve seen a lot more problems in my friends who come from non-flouride societies with similar dental hygiene to myself.
Sometimes the crazy people are right.

Someone close to me used to have all kinds of health problems. These included digestive tract problems, skin problems, and many others.

After seeing many doctors and specialists over many years, they were worse off than when they started. They decided that maybe it was something in their diet. They eliminated pretty much everything except water from their diet, and that did not work.

Shortly after, they went on a trip where they were off grid for a few weeks. During that time, the health problems started going away. When they got back to civilization, the problems started coming back.

That's when the thought hit. What if those crazy people on the internet are right about municipal water?

After some experimentation, it was determined that chlorinated water was the culprit. They've moved to a house with a well and are much better off than before.

Since then, I've met other people with similar health issues who have benefited by eliminating chlorinated water as much as possible (drinking or bathing). Some have installed large carbon block filters on their municipal supply.

Chlorine has had undeniable public health benefits, but it is also a poison, and affects some people in a very detrimental way.

I think here is where a potential misunderstanding is. I've said nothing about "people shouldn't be allowed to say certain things", I've been asking purely about whether or not there should be regulations or items removed from a site, including illegal material. If I'm understanding you correctly, you're looking at this purely as a censorship issue. There's a difference here, and one that's worth at least acknowledging. For example, if someone is posting something that is illegal, the appropriate authorities will both remove it from the post and attempt to go after the persons responsible for posting it, whether that's online or in the real world.

There's room for discussion, but first we have to figure out exactly what where' discussing, otherwise we're just taking past each other, and accomplishing nothing.
I’m Donating My Birthday to Hurricane Victims in Puerto Rico: What’s Included
One problem I have with economics is the tendency to proclaim proof after just one data point and that too in hindsight.

Just like this particular article is doing. It proclaims people doubted government can simulate growth and now recession has proven them wrong. Isn't it in hindsight and just one data point?
here, i'll tell you why you're getting downvoted. the problem with what you're saying is you can apply it to literally any price point. in other words, it's a meaningless statement.

$100 or $10 are certainly cheap, but is not affordable for a lot of people in this country either. there are points in my life when i couldn't spare $10 or even $5. it might happen again if something bad happens.

in fact you could probably go down all the way to $1, or a fraction thereof. what about the single working mom who needs that $1 to ride the bus or the homeless person who uses the coin-op restroom? there's plenty of them out there, and they can't afford it.

at the end of the day, $200 for a foreigner, uninsured, to receive prompt attention, stitches and a short hospital stay with drugs, is cheap. the world is not a fair place but this isn't what should be worrying us.

One feature that differentiates Linux from other systems is the sheer amount of choice that you get.

For example, with Linux I can choose GNOME, KDE, a selection of other desktop environments, or I can choose a simple window manager like twm and sort of roll my own environment. Or maybe I could set my system up so that it runs without a window manager and just gives me a full-screen emacs environment.

With Mac OS, for example, someone else made all of the choices and I have to live with them.

What Google is doing will probably end up getting pretty close to your vision, but I suspect that the end result will be very similar to Android - a system that's technically Linux at its core, but where all of the choices have been made for you.
I love that piece, I think the problem is the opposite though, not complicated enough models, in part because they are trying to model an absurdly complicated system with overly simplistic assumptions. This piece highlights that attempts to simplify the model (variable X doesn't matter!) have failed to fulfill their promise.

"Biggest disadvantage: If you drive on mostly flat terrain, there's no real benefit – it might even slow you down."

I'm from that country with the bikes 'n dykes (The Netherlands) and lately it seems a trend that elder use e-bikes instead of whatever else they were using (car, moped, bicycle, legwagon). They're severely slowed down if they were to use a regular bike. This way, they can get some fresh air and actually see some of nature and adjacent cities/village.

The biggest disadvantage to me is the high price. Combine that with these elder who'd also use these e-bikes to go for longer routes but then they'd not put their bike locked securely (and you should use some good locks). Cause yeah, losing 1-2k EUR from just doing groceries is a shame. They're also a bit more difficult to transport in public transport than a regular bike and more so a folding bike (latter is freely used on Dutch railways called NS).

I also notice that the e-bikes can pass me on longer courses, but if we're going from traffic light to traffic light I accelerate way quicker on my regular bicycle than e-bikes. If I do my best, I can slowly pass an e-biker.

If you wanna take your kid with you, a "bakfiets" (a bicycle with a way to transport items in the front of the wheel see [1]) also works. Especially common in Amsterdam.

The Cube Design Museum in Kerkrade had an exhibition (in NL/EN/DE language available) about bicycles with all kind of bicycles of the past and the future, including experimental designs. When I went, IIRC in september 2017, they also had an exposition about toilets, and a floor about past failed designs (a lot of electronics but not solely), There's World of Bricks (Lego) as well in the Continuum Museum nearby. Recommended! (Disclaimer: not affiliated.)

I imagine I could spend a ton on personalized prescriptions but my normal prescription is insanely good. I'm lucky. Personalized prescriptions (free form, ...) are great for people with difficult prescriptions but unnecessary for the common case.
Yes, yes, Scarlett Johansson.
I recently read 'Quantum Night' by Robert J Sawyer, which explores psychopaths, people with an "inner life/monologue", and "philosopher zombies" -- people who don't have such an inner monologue and therefore are fairly manipulatable.

Part of the book's setting is that most people lack an inner monologue, a fair amount of people are psychopaths, and few people are "normal" non-psychopaths with inner monologues by a ratio of 4:2:1.

Even if you don't enjoy science fiction, it's an interesting read.
They disn't use sleeping darts because the police are also loose cannons aiming deadly weapons irresponsibly, as we can see time and time again.

It's very easy to end up with messy/unusable history or even lose work when you have multiple people working on related parts of a project with outdated branches and limited git knowledge.

I have been bitten by coworkers submitting preposterous pull requests because of a lack of understanding of what you can do with git and how it works that could have been avoided by taking the time to really grok git.

They aren't "foreign companies"; they're multi-national entities doing business in the UK. If, in the course of doing business here, they generate costs for the nation, they should be expected to help out. There's no reason the UK taxpayer should foot the bill for negative externalities generated by the business practices of multi-national entities. They can either invest in whatever it takes to solve the problem themselves, or they can be taxed so that state can take care of it for them.
Well. To be sure, it would be awful messaging for the organizations to run that message. If they alienate FB or Netflix then they could lose much more than they realize (as apparently some donations are done anonymously).

I think there's probably something to this. Plenty of people complain about the HRM, myself among them. Weird things like spikes of 170+ bpm while doing nothing but walking, while at the same time recording 100 bpm while doing sprints? Pretty normal on the Fitbit, in my experience.
A couple of anecdotes to share.

My wife went back to her hometown in southern Taiwan a few years ago to help take care of her ailing father. One day while at the hospital she saw a tour bus pull up, and forty tourists from mainland China disembark. Their tour of the local sites included a checkup and some tests by the doctors in the hospital. Works out well for them and the hospital, which is not nearly as busy as the facilities in Taipei.

People clogging up emergency care facilities with common colds and minor ailments is common (as noted by others on this thread). There are several negative side effects including patients expecting to be prescribed something even if it's not warranted. If it's antibiotics, that's a problem because people can build resistance to antibiotics. I also believe there can be a kind of assembly-line mentality taking over among the staff at some busy facilities, with doctors spending only a few minutes with each patient. This can unfortunately lead to truly serious cases being overlooked.

For chronic conditions, the quality of care varies quite a bit. One complaint I've heard several times is sometimes there is no coordination between specialists -- it's up to the patient or family members to reach out and make appointments and communicate test results and the conclusions of other doctors. Lots of things can go wrong, and I fear some patients fall between the cracks.

Dental care can be very good and very inexpensive - my dentist here in the U.S. has complemented the skills of the dentists back in Taiwan who put in crowns years ago.
