Interesting math story problem, but probably not much use for real lifeguards.

Is there any observational evidence that lifeguards choose paths this way, rather than the direct line or shortest water path?

Perhaps they do some optimization, particularly for very oblique angles, but in real "shoreline" situations, I expect wave and current action will dominate the optimization, rather than the delta between running and swimming speed.

Guidelines for lifeguards talk about avoiding water entry if possible and definitely avoiding direct contact from the victim if at all possible (https://www.sauvetage.qc.ca/en/lifeguarding/rescue-technique...) but don't really address the run-vs-walk choices.
As insufferable as the bitcoin True Believers are, so too are those who claim it is trivially true it is a worthless scam currency. If scientific inference on the world were easy, we wouldn't be so awful at predicting the future, and we wouldn't rely on randomized experiments (or observational causal inference) to uncover most truths we have uncovered as a species.

The technology and use of bitcoin as a store of value is an open experimental question. The experiment is currently in progress. To believe you can infer the truth so clearly, either for or against, is the natural naïveté of the uncalibrated human mind.

Not to claim no one can ever know the future, or that some people aren't talented at prediction. All the same, there are particularly bright people who can't come to an agreement on the future state of bitcoin and was it will offer. Why is that? Is one set simply wrong, so clearly?

I wouldn't call it a particularly rigorous analysis and it provides no more incite than what has been published about Willy before.

Mark Karpeles fraudulently buying up $112 million worth of bitcoin in two months when there was no fiat on the other side of the trade pushed the Bitcoin price up. It's as simple as that.
"Contagious" by Jonah Berger talks about how anger and anxiety makes people share memes. I find that Facebook and the organizations that use it are NOT interested in my mental health. They're interested in triggering my sharing response.

I don't mind using Goodreads because Amazon and I have the same goal: they want me to buy and read books, and guess what? So do I.
I'm looking forward to an hybrid F-150. It would be nice to have the batteries under the bed so I don't have to buy the sand in the winter. Since the F-150 family is still the best selling vehicle in the US, its going to be very interesting when they make the move. A full electric is really going to have to some decent range when towing or have a quick charge time to be accepted.
Hire internationally. A good mobile developer from a 2nd-world country (say, Czech Republic, Ukraine, or Russia) goes for $20-30/hour on Upwork. You do pay in communication costs, but their development chops are usually as good or better than devs coming out of top American universities. And the supply is certainly much deeper than "top American college graduates living in the Bay Area" and probably a fair bit deeper than "all American programmers". I know multiple startups - some completely bootstrapped, some venture-funded - where the majority of the development team is abroad.

AppAmaGooFaceSoft hires internationally too, of course, but they tend to go for graduates of top Chinese, Indian, and Taiwanese universities, and less for the self-taught kid who has a computer, an analytical mindset, and a lot of free time.
It "worked" but as someone with a 3Dfx at the time I'm not sure I would call it performant. I'm not sure N64 emulators were close to performant until I had a Geforce 3 Ti or so...
I always wondered why the Phone app didn't have location services on and a big button that when the user presses it would grab the GPS coordinates and reverse geocoded address then have Siri read those over the phone line. That way no 911 center needs to upgrade and no telcos need to change infrastructure.

A simple button right there on the phone that sends the following sound (in best Siri Voice imitation): "This phone is likely located near 1600 Pennsylvania Avenue North West, Washington DC, Latitude North 38° 53.8258', Longitude West 77° 2.1927' admire.admit.hulk" (last words intentional: http://what3words.com/)

The analogy that I use is this: equity is Bison dollars. You could trade in your equity for a princely sum if the founders' world-domination plans go off without a hitch, but a) that's a big if; b) in the meantime, you can't eat those stocks, nor will your landlord accept them as rent.

Which is why anyone who offers to pay me in equity instead of salary gets a polite fuck you, and I would only accept partial equity compensation if the salary part is sufficient to meet all my living expenses and then some.

Of course human intelligence also stumbles on planing problems of true complexity. So it is still possible that human intelligence does something like a naive graph search, and this is good enough in the common case.

I've enjoyed playing with the program (and I like seeing the different ways people design computer languages for logic).

Another feature that might be interesting is to be able to ask the program for another example or counterexample. I imagined an "Another" button below a given example or counterexample. This is assuming the program already has the ability to enumerate worlds.

this correlates a bit. In my circle common is to use fb only as messaging service. most friends dont have fb app even installed anymore as the news feed is trash. I assume this move is to try to get these users back.
Indeed, we have to be confident that the mechanism of intervention will have the desired effect, and in time before we run out of antibiotic alternatives.

I say that anything less than that is worse than useless, because we're spending wasted effort (mindshare, attention) when time is, to the best of our knowledge, running out.

Now i don't know that personal activism and moral campaigning will be insufficient in this case, it just smells that way to me. It also has a certain fragrance of moral superiority and virtue signalling about it, which i guess triggers me, or something.
I don't think introducing another recurring payment is the best thing for society. The market will be ready for battery leases when the average person can't afford their own battery outright.
> Everybody uses FB differently. Some people use it to share and read news. Others as an "aggregator" for different services (Insta, Twitter...). Others for groups. Or chats. Or to connect with businesses. I use it exclusively to share posts and pics with friends.

> Wrapping up, I'm sure that Facebook has identified 5-6 clear use cases of its platform. Why isn't the news feed tailored for them? I simply do not understand it. Give more of what I want, or my engagement will drop. Give me my friends posts, and a few ads in between, and I'll be a happy Facebook user, surely it can't be that hard?

You're approaching this wrong. You're not Facebook's customer, you're it's product. They don't care how you want to use it, they only care about what will keep you on it and seeing what they want you to see. They're not going to optimize their website to fit your preferences. They want to maximize their value metrics, not yours.

I'd expect traditional future buyers (if that is the correct term?) to be much less likely to be swayed by advertisement than the new market segments that could be attracted with bitcoin futures. Kind of logical to focus advertisement activity on the latter group.
Strong disagree with Svip. Training doesn't make good drivers. Who is going to ensure the trainers are good? Who is going to test that the training is being effective? More restrictive licensing, with more consistent requirements, might make a difference, but is politically nearly impossible. As long as many people will be inattentive and unreflective humans, there will be bad drivers. Unless you're going to support a policy of refusing to allow a large percentage of the population to drive (like, say, how we restrict most people from performing surgery), you'll have bad drivers.

Bez's proposed solutions have the benefit of being politically palatable, and aligning actual driver behavior with public safety.

You can call any narrative as make-believe... what's your point?

Again, not sure what you're disputing here. That World Wars weren't caused by unbridled capitalism?

What can't be blamed on Indira? She nationalized most banks, airlines etc. basically snuffing out the nascent private sector and heavily regulating the scraps that were left.

Extending SS7 to your phone seems... complex.

The more I think about it, having your phone send an SMS to 911 with your location as soon as you dial 911 seems really simple. SMS to 911, where supported, must already be special-cased. Carriers can each deal with that and communicate that back to the 911 call center in their own way (obviously negotiated with the 911 agencies) and phone manufacturers need only do a single (simple) thing.

There would be a lot of flexibility there too. Your phone could choose to update the location as it changed (moving vehicle) or as precision increased.
The study's methodology of comparing only the lowest-priced tier service isn't that great, because it may be more indicative of the degree to which a provider is willing to cross-subsidize service tiers rather than real cost efficiencies. To take the top 3 providers from the chart on page 8: FiberNET in Morristown charges $200 for gigabit, Sebewaing Light & Water charges $160 for 1000/100, and LUS charges $109 for gigabit. The "market rate" for AT&T/VZN/CenturyLink is $70-90 (excluding promos).

There is also the question of what happens going forward. Quite some time ago, Easton MD (on Maryland's eastern shore) put in a cable internet service through its municipal utility. Today, you can get 200/10 for $100/month. Not bad, but head a bit east to Salisbury, MD and you can get 1000/35 through Comcast for $105 ($80 for the first year). That's the big fear with municipal services. Upgrading head ends won't get you press like rolling out a broadband service in the first instance will.

That being said, municipal broadband certainly has a place. Maryland is spending a bunch of money building a fiber backbone in the rural parts of the state, and municipalities are hooking into it: http://www.westminstermd.gov/419/Westminster-Fiber-Network. These are places that don't have the population and density to support potentially even a single private provider, much less multiple competing ones.

Nice. Having read hacker news for years, I remember a lot of comments from angry Americans who were offended by Europeans mocking them about their broadband prices, and telling them that they were being screwed by big American telcos who formed an monopolising alliance artificially keeping prices up.

The comments used to range from "the country is just too big, the infrastructure work doesn't compare" to "European broadband infrastructure is paid by the states because of socialist-type taxation".

And finally, after years of municipalities fighting big telco, it is becoming ultra clear that yes Comcast, TWC and co have been screwing the American people for a looooong time.

And hopefully this is only the beginning, prices still have a long way to go!
>> I doubt any of this manipulation is even illegal?

That was my first thought also... in stock/futures trading world, this is 100% normal business as usual. The idea of buying all the available XYZ to run up prices is a valid move for a hedge fund with sufficient capital to do so.
Precisely -- thanks for clarifying!
I'm not sure how you can say hierarchical organizations that use violence/coercion are in any way anarchist. Anarcho-capitalism requires voluntary engagement in a system of contracts and so forth. (Whether that could actually work in the real world is debatable but beside the point.)

Am I going crazy? I provided an honest source for my point. It was pointed out the source I used is likely biased. I therefore provided a second independent source that agreed with the original source. No one has yet provided any source that disagrees with anything I stated or anything stated by either of the sources I linked. And yet is a fallacy for me to ask that someone should have a source if they are going to argue against the two sources I provided?
I'm not sure you read my comment...we are saying the same thing.
And, it would produce literally no value (unlike VC investment in companies). There are so many ways to look at crypto that makes it seem like it's incredibly undervalued and this kind of thought experiment has been done many times in different ways (with the example for the thought experiment changing over the years as the crypto market cap has grown to surpass the example...e.g. gold, Western Union money transfers, etc.). But, unless and until crypto provides value to justify it, it's all just speculation.

Right now, BTC is a basically useless asset. You can't buy things with it (without paying more than using dollars). You can't cost-effectively transfer money with it (fees are too high and transaction times are too long). What can you do with it? Sit on it, and hope it goes up. (Which is what I'm doing with the small amount I still hold.)

I'm vaguely optimistic about cryptocurrency, in general, but the current state of things makes me think there's too much money chasing too little value...all that money could be going into companies that make or do useful things. But, instead, it's just burning electricity.

Not directly a Bitcoin issue, but 99% of ICOs are blatant and obvious scams, most small altcoins are blatant and obvious scams. Even some major altcoins are blatant and obvious scams. I feel like there's a more than even chance of this whole thing ending in tears in the next couple of years, even if cryptocurrency eventually (like five, ten, twenty, years down the road) wins.

I don't mean to say you're wrong. More money will likely pour into cryptocurrency as people with money either fall for the ponzi schemes that surround it, or as it actually begins to produce some kind of value and becomes a useful tool for normal people to do normal things with it. We can't begin to compare crypto to the internet (as I've also seen people do...suggesting crypto adoption is now where the internet was 5, 10, years in, or whatever, just because the same number of people are hoarding coins as were on the internet at some early point) until you can actually buy pet food using it (or do something else of value). It isn't a revolution if it just sits in a vault like gold.

The key is:

>you could come up with some rotation mechanism so that only certain accounts can participate in a certain round

which is impossible to do in a way that can't be exploited and is fair (without relying on some external source of randomness). And I advise against trying to come up with a way to do so because the internet is full of failed attempts.

This was my thought. I think the article reads almost like a children's Did You Know? kind of book: it presents the problem and just enough background information to understand it, then leaves the mystery for the reader to go and find out more.

I could see the argument that there is a fine line between leaving a bit of mystery and just plain lazy writing.

The PSX was one of the first consoles where emulation didn't typically imply piracy. Because the PSX used the same CD-ROMs as computers, you could stick your game CD in your computer and play it in an emulator.

Yes, the British imposed taxes on Indian salt produced and sold in India in order to force people to buy imported (British) salt. Millions of people died because they literally couldn't afford salt any more.

This eventually led to Gandhi marching to Dandi to deliberately violate the salt laws and was one of the key moments in the struggle for Indian Independence.

It really breaks my heart that the British killed tens (maybe hundreds) of millions of Indians for no reason at all and they've gotten away with it both in terms of any actual consequences as well as in the realm of public opinion. And to make matters worse, we still have so-called British intellectuals who like to argue that colonization was somehow a good thing for India.
