If you had a phone and Internet to call Uber, you also had a map. Of course, I don't deny that it's much simpler with Uber or a taxi app, but telling that Uber is the only mean to get a taxi in a foreign country is like telling that people couldn't eat before inventing a spoon.
There are so many other spectacular things with this bubble, down to the nature of the actual instrument itself. Cryptography, decentralisation, miners, forks, etc. The IT bubble was still a stock bubble. I think this is something new.
In retrospect, the episode sullied the reputation of everyone involved. If Perelman were less private it likely would’ve created less space for others to fill the space. It made everyone, including medalists like Hamilton and Yau, look like publicity starved careerists. I don’t have an opinion about whether careerism or a need for publicity is bad but I can confidently say that both are viewed negatively inside the mathematics community. It was a weird situation.
IIRC like-kind treatment was never made available, with the new tax plan or without.
It's Bitcoin Scale!
Except the industrial value of gold which is around 10% of its use and not the quality/pure one, how is gold better than bitcoin? The favorite argument and the only argument is its history, yet when someone tries to use the same historical argument of bitcoin going up and up for 7 years, the elitist, NY folk will quickly follow with "Past performance is not an indicator of future outcomes".

I think people here are just salty because they think they are smart yet didn't saw the value in the crypto/blockchain, especially that is up their geeky alley.
My biggest concern with the lack of underlying utility / value is does currency have any real, long-term value if there is no sovereign government willing to go to war to defend its long-term interests? Or if there's no underlying system of law to protect those that engage in it? Is the plan that sovereign governments use their resources to reinforce a currency that undermines its own?
I started to get tempted to get in the crypto craze after resisting it since 2011, until my mother, who can barely use a computer, told me last night "What is this Bitcoin that everyone keeps talking about, everyone is getting rich, we should get in on it". That was a definite sign to stay away.

She was still tempted even after I explained the bubble and reminded her that 2000 of our people died last time something like this happened in 1997. A lot of people are going to suffer this time, it's not going to be pretty.

Javascript also does not have access to the chrome of the browser. Unless it's running in a WebExtension context, in which case you can also run WASM there.

WASM can CALL INTO JAVASCRIPT CODE. Which means it can do anything JS can do — in a "clunky hack" kind of way, sure, but people are building sugar on top of this already: https://github.com/koute/stdweb

So it's not the kind of sandbox you're thinking about. It's literally the same sandbox as JavaScript itself.

Also, I just realized — you're probably thinking of "compiling to JS" as in TypeScript/BuckleScript/Elm/ghcjs/ScalaJS/… — and yeah, that isn't easy to replace, because you'd have to implement a whole garbage collected runtime for WASM currently and that's kinda ridiculous.

Others (including me) are thinking of "compiling" as in Emscripten, and WASM was literally created to optimize this at first.

People naturally form us-vs-them tribal mentalities, and the fact that this is the top comment of this post indicates that its a tribal mentality that's leading it to be upvoted.

It's like saying on a Roy Moore post that the investigation was carried out by CNBC: it leads to Republicans invalidating any finding of the investigation. This default of ignoring any information from the Other Side is what almost got Roy Moore elected.

This us-vs-them mentality needs to be noted. The fact that this comes from a think tank does not immediately mean they don't raise a good point.

Sure, the emitter could, say at $40,000, buy the 275 BTC. If the option expires in the money, the emitter would deliver the BTC, and receive $50,000 each, making a tidy $2.75m profit in addition to the $1m premium. But BTC could also fall back to $10,000. Then the emitter sits on a $8.25 m loss (minus $1m premium). That's really the issue.

It's feasible that the emitter owns 275 BTC already (or more), and is happy to give up the upside beyond $50,000 on 275 of them for $1m cash now (in other words, he wrote a covered call). That's the most likely scenario in my view.

(If you delta hedge, you could manufacture the call, and then are not so much exposed to the price of BTC, but to its realised volatility to expiry; the emitter would be short vol: if vol is higher than expected, they'd spend a lot on the delta hedge (due to gamma), if vol is lower, they'd spend less and make money.)

> If you look at somewhere like London, then pretty much every busy intersection, every public square, every station, every bus, every train, etc has CCTV.

My experience as a londoner is that privately or quasiprivately operated spaces (including trains and buses) and roads do but public spaces like squares or parks don't. When I was mugged in a plaza there was no public CCTV coverage but the police requested CCTV footage from a private gym bordering the plaza. I think that's pretty normal for london.
You could use arguments easily on the same moral parallels are those to exclude particular races, sexes, etc. I’m not calling you out - I think you’re correct actually, in the observation. But some biases are more politically and culturally palatable than others, even when there isn’t a whole lot of daylight between them.

You shouldn't have written "dismissed" either -- the OP just posted a link and noted that they were conservative. Maybe "implicitly dismissed", but even that is pretty paranoid; though, to be fair, that is probably what the OP meant.

Clark Is Hiring Full Stack Software Engineer
I see your point but you didn't really tackle the problem at hand.

To detach the situation from current feelings, let's take a time trip back to hypothetical year ~1975.

Let's say it's illegal to register a NGO, company or anything that has a rule of "no sexual group X allowed". Now let's say that there is some guy who is absolutely brilliant at playing the violin, but has at some point allegedly done some homosexual approach to straight guy. Which any gay would have just brushed away, but now it was taken as harassment.

We have obviously created a situation where it's impossible for that violinist to take part in any orchestra. No "only gays & women orchesta" is allowed by law. Society completely wastes that human resource. Some male musicians somewhere possibly have slightly better work security. But the cost is that millions of people never hear the recordings of that great violinist.

You have to pick:

A. Allow organizations to be completely self selecting. This would have a set of short term problems and it's currently not kosher at all.

B. Allow alleged transgressors to somehow wipe their record clear. Seems practically impossible during internet age and click headlines.

C. Force people to be cool about people who have allegedly transgressed in some way in some other social setting. But now you lose productivity of whole teams, not just some individuals here and there.

D. Lose a lot of human resources. And probably for petty reasons. If allegation is enough, you can destroy too competitors easily. As shown by the red scare, Stalins purges, etc.

This was originally a case about a programmer allegedly groping some women. Seems like if you could start a company of "former sexual harassers inc", you could soon hire lots of splendid talent dirt cheap. Then you just need to somehow hide the origin of the products being made to the consumers. But soon even that won't matter much if there is anything to be learned from the music industry.

How would you describe it if not using the word "donations" then?
(Trying to group related points together)

> Even in bitcoin, all nodes must eventually be able to communicate with the p2p network (and therefore be able to receive all other nodes' blocks, honest or otherwise). How could you tell if there is a fork, otherwise?

The security-correctness proof of bitcoin doesn't depend on "honest nodes reliably receiving all honest nodes' blocks". Actually bitcoin is simple in that it doesn't try to distinguish between honest vs malicious, the security argument just says with overwhelming probabliity that any colluding subset of nodes with >50% computation wins.

----

> In other words, the adversary is allowed to send individual messages to individual parties, but not prevent a party from receiving any other party's message within a round (which corresponds to the time between blocks).

But transports are unreliable and systems buggy, and so this could happen anyways in a real run of the protocol.

> An adversary could send a message to a slot leader and perform a DOS attack to prevent him from receiving other messages from other parties, and this seems to be an overlooked attack vector. Although, on the other hand, I'm not sure how the adversary would know which ip address to perform the DOS attack on. [..]

Honest parties of the protocol have to be able to contact the leader by the normal operation of the protocol, so the attacker could just hook into this mechanism.

More generally, these are not holes that one wants to leave untreated by the protocol, it can open up escalation / chained attacks.

----

> The point is to prevent long running forks. "sort | head -n1" would work if the branches were all static, but not if an adversary with a large, but not majority stake, saved both branches and then added a block to them, the new longer branch would be preferred. [..]

When I say `sort | head -n1` I don't mean "also prefer longer branches", I mean only `sort | head -n1`, unconditionally on all fork-points. Assuming honest nodes can all reliably broadcast (which the paper does, even explicitly on page 16), this is enough to achieve the "unforkability" property. (The attack you mentioned wouldn't work because the longer branch would still be ignored.)

> Handling the case where all nodes don't have reliable channels to each other is overkill. You just need to handle cases where some nodes don't have reliable channels.

I agree the former is overkill, but the security assumptions of "forkable strings" don't handle the latter case, it assumes it's already handled.

Believe I heard about a project a UW student did predicting crime in San Francisco based on volume of vulgar tweets in a given area. Not sure if it's on github anywhere but you can always start with that idea. Nothing about specifics of the crimes, just where a high volume of them would be located.
I think it’s a terrible playground.

Of course I must say I don’t wish any disprespect to pete_b. Efforts like these always appreciated, and it does have value, at minimum allowing others to learn and evolve from it.

It could just be so much more intuitive to illuminate the most important flexbox levers and more effective as a productivity tool to quick prototype results for use in other code.
(This is not a statement about their journalistic quality. But:)

Axios is an interesting example of changing the format of news story writing to be both more concise and more visually scannable. And, thus, easier to glean important info from.

See, for example:

https://www.axios.com/wearables-still-slow-to-catch-on-in-th...

Compare to a more traditionally written article:

https://www.nytimes.com/2017/12/21/us/politics/facial-scans-...

I do think the way we communicate with the written word online needs to continue to evolve. The way we read and learn is certainly very different.

Anyway. That's what this article makes me think of.
It very well might if it were useful as a currency.

Hyper-deflationary token systems that not only don't scale but lose their utility when adopted are horrible currencies. The more people use a particular block chain the less utility it has because the system doesn't scale in either transaction volume or token price stability.
The technology behind it could maybe one day cause "the new dawn", but there's 0 chance this is anything other than people going full retard. It's like a smaller scale, equally as stupid/shitty version of that tulip craze that happened in the Netherlands like 400 years ago or whatever.
Alva: A new digital design tool built for cross-functional product teams
There exists no computer in the world that can combine the memory of hundred of thousands of police officers together. With video footage, that's not necessarily true.
Right, but what about all the times that crimes aren't being committed? In Illinois, the law is that the cameras must be able to record 10 hours and must be on when not in the car or the officer is talking with a victim, witness or confidential informant and those individuals request the camera be turned off [0]. That means that whenever the office enters a private area, where one expects a reasonable amount of privacy, that privacy is gone as long as the officer if following the rules. There are, of course, private places that one would not expect privacy such as any business that states they are recording video.

"Credible concrete arguments for why some article might be flawed or biased tends to carry a lot more weight than just attacking the place it was published in for its political views."

That all depends. When it's been hidden, I think it's essential to know the ethos of the organization that paid for the work to be done and disseminated. It isn't plain in the piece that it was brought to us by the Manhattan Institute, which is one of many think tanks producing "journalism" that has never, ever found a problem that the "free market" wasn't the precise cure for.

> there's the part where they get to look through all your social media accounts and hold you indefinitely

Wow, so I've been hearing chatter about that for a while now, but I had no idea of how common it was.

I would like to ask you for some clarifications if you don't mind.

Do you think that such social media snooping as you described is fairly common? Do you think you might be in some classification of people that make it more likely? What do you think would happen if you refused? What do you think would happen if you legitimately deleted all of your social media accounts, thus making it impossible to comply?

Thank you kindly.

Well, Ethereum was basically an ICO and you're seeing lots of investment and potential development in that space. Even my company is planning to have a division start using Ethereum as a development platform over the next few years, and it's a large corporation.

As for the rest, most of those just raised their money in the past year or two and haven't had a chance to actually build their platform yet (if they're ever going to, I have a feeling a bunch of them are going to end up being vaporware).

Ask HN: Modern clinic IT?
Some friends of mine are setting up a free clinic and have asked for help with their IT. Right now they're accessing a Cloud-based medical records system from a handful of donated Windows laptops. The functionality they need is a browser, printing, and uploading files from their scanners.

Their current woes revolve around getting printers and scanners configured on all the laptops, but I'd like to think a little bigger than that.

If you were setting up the IT for a small clinic from scratch, what approach would you take? Manage individual devices? Thin clients pointing to the Cloud? PXE boot from a local server?

Keep in mind that they don't have an IT person on-call, so we'll need to find something stable or at least one that doesn't fail catastrophically.
It costs more than 40$ to store then retrieve value. That's unfavorable for the vast majority of people in those countries and not cost effective for those with means.

You can't tackle homelessness at the city level; a city doesn't have enough resources once word gets around and homeless folks start moving in to take advantage of your effort. Until we have better support at the national level, any plans that have ending homelessness as the end goal (or even just warehousing huge numbers of them in shelters, as in pdx's case) is doomed.
They would also enjoy the opportunity to simply walk around a bit, or maybe grab a coffee.
Malicious intent must be assumed. The body cameras exist in order to be a deterrent to malicious police behaviors and as such any system which puts the officers in charge of the functioning of the cameras, and which does not heavily discourage or prevent police from operating with a broken or malfunctioning camera is failing in its primary mission. It should be illegal for an officer to operate or be on duty with a broken or otherwise non-functioning body camera, and the footage from body cameras should be held by an independent third party that is not subject to oversight or control by the police (FBI might not be a bad idea).
