Pittsburgh still is measured to have bad air quality compared to other cities, but it's certainly not bad enough that you actually notice it.
How Wi-Fi Works
It's not all transactions, just social ones. People share their personal information on social media all the time, particularly information that relates to a social interaction. Since money is often a component of social interactions, a public record of social transactions essentially adds no information to what people have already voluntarily posted on other social forums. I use Venmo all the time, and since the dollar amounts aren't shown (only the participants and a short memo) I generally feel comfortable with public transactions. More sensitive interactions I make sure to set private.
> ITER will not capture the energy it produces as electricity, but—as first of all fusion experiments in history to produce net energy gain—it will prepare the way for the machine that can.

So this is a very large and expensive project that will never produce any actual electricity. Seems at high risk for budget cuts. No one can predict the political environment over the next decade. If it's anything like the last ten, this project is at risk even of they can stay on schedule and within budget.
I saw this a while back and thought it was a good summary: https://youtube.com/watch?v=L0KuAx1COEk

I forget the current best efficiency, but it's getting close.
I agree. The most important quality I try to cultivate is what I guess many would call 'good judgment', and others 'intuition'.

I've worked as a freelancer, lead front-end developer, and contractor, and ranging from 'stuck in the nineties' to 'use whatever HN talks about for the front-end' companies. One of the most important lessons I learned is to use the right tool for the right job. Also to not let 'purity' or 'elegance' get in the way of getting it done (which is difficult for me). But also to never confuse 'getting things done' with laziness.
Restaurants are definitely accustomed to splitting bills in Salt Lake City as well. I was surprised to come to a larger city like San Francisco and have to chase people for their share since most restaurants won't give individual receipts.
How is showing me the lists I'm on a privacy issue?

Doctorow was on over 3,000 lists. Unsubscribing was a lot of work. The cynic in me says that's how MailChimp wants it.
The right question would be "Not if the website uses client certificates though?". As far as I know, TLS connections using client certificates can't be proxied, since the MITM proxy would need to have the client certificate's private key.
Ask HN: As a fresher, how do you decide which domain you are inclined towards?
As a student or as someone who has recently graduated, how would you decide which domain you are inclined towards and then decide to pursue a career in it?

I have met quite a few students and recently graduated freshers who have had good grades and a sound technical knowledge, but are clueless about the domain that they want to pursue a career in. Having a plethora of options to chose from only makes this decision making process harder for them.

So my question is, what advice would you give to someone who is just about to step into the real world and has no clue as to what domain he is interested in?
I don't think there's some huge unmet industrial demand for tritium, though, and even if there were, it'd probably be more cost-effective to simply breed it out using an existing reactor in controlled circumstances than to try to distill it from millions of tonnes of radioactive wastewater.

And unlike helium, it's not worth stockpiling tritium now if you don't have immediate uses for it, as it decays in storage.
I feel like it's a pretty recent development that investors don't expect their investments to turn a profit.

Quite simply, if you have the ability to look at code you wrote recently and ask yourself, "what the hell was I thinking?"
Another 'how [tech company/product] is ruining [social norm]' thought piece.
If we were to somehow perform a Principal Component Analysis on the amorphous, contradictory mess of "hippie ideals", we could probably distill them down to something like a call to implement a post-scarcity, socialistic society with few restrictions on human social behavior.

Of course, that kind of radical change isn't achieved by smoking pot and playing the guitar in downtown San Francisco. It's achieved by major technological changes that would make such a society even functionally possible, like practically-unlimited renewable energy sources. Needless to say, nobody involved in the 1960s counter-culture movements was in any position to actually implement the kind of changes needed to realize the grand vision of an ideal hippie society. (Some of them tried to do the next best thing, and form their own mini-societies in communes out in the country, all of which ultimately turned out to suck.)

I would also note that another 1960s icon, Gene Rodenberry, at least seemed to realize that the kind of changes needed to implement a hippie utopia would likely only be possible after many other practical societal problems were solved via technology.
LOL, please show me an example of a "window where you can look at a reactor core". Show me a window protecting someone from thousands of rads/hr from an active reactor core. Please :) And no, the radiation seen in space exploration is not comparable to the levels at Fukushima. Not anywhere close.

Have you ever actually seen an endoscope? Do you have any idea how complicated they are, how many optical elements they have and how precise the tolerances must be?

Did your study of wikipedia reveal the extent of transmission loss in rad-hard optical materials after exposure to levels of radiation near those at Fukushima? Because the link I gave you does. Read that and tell me how long you expect your fiber optics to last down there. I'll give you a hint: not very long.

Tell you what, just make a sketch of your "low-tech" endoscope that withstands hundreds of Sv/hr, deals with hundreds of degrees of internal heating, is waterproof of course, and is robust to extreme physical abuse. And then come up with a way to remotely maneuver it into place through hundreds of meters of industrial wreckage, without using a robot.

Then get ready to be famous, for your brilliant low-tech solution will be lauded by the international team of scientists and engineers working on Fukushima who simply hadn't thought of it for over 6 years.
Bitcoin is supposed to be a currency, so there are many non-technical aspects of it that need to be properly handled. If the people working on the code take it upon themselves to make the non-technical decisions too, they need to be held responsible for the outcome.

This really gets at the heart of my dislike for cryptocurrency -- most proponents believe it's supposed to be decentralized and free from the control of government, but it's actually centralized under the control of a small group of unelected programmers (who seem to misunderstand how human societies, currencies, and contracts actually work), and there is no recourse when they make bad decisions except to fork the blockchain and the code. It's really a step backwards in terms of governance compared to, say, fiat currency with democratic governance. This applies to most cryptocurrencies I've seen, not just bitcoin.
I did my undergrad in biophysics and this is basically a simplified version of the currently accepted view. We now also know that some proteins fold in units, and can have multiple stable fold stopping points along the folding paths, and a good deal of proteins never really have a single stable fold at all. Basically google scholar "protein folding energy landscape" for more details.

The LEGO Group has some rules under Play Fair on their website:

The patent for the bricks ended in 1988. But the Minifigures have a copyright. As long as you don't use all this for commercial purposes and profit they are very relaxed. Because their fans and community are a very important part of the LEGO brand.
Yes. The incredible amount of bridges (most anywhere) makes it so a lot of roadways, be it the bridges themselves or just general weirdness begat from building roads in a river valley, are super not safe for bikers.

I'm not sure where you are getting the 250-300W/m2 of irradiance. The standard value used in all solar industry calulations is 1000W/m2, but in practice, you should expect to see 800W/m2 at sea level and moderate lattitude.

I agree generally with the reactions of disbelief in reply to this article.

Its in a company.

I know of no hindrance to company policy or ability to make the most rational decisions about networking security, from the starting point of not compromising security, and forcing users or client applications adapt to the needs of compliance with data retention and discovery rules.

Security measures must come first.

If security is necessarily compromised by the requirements of compliance systems or protocols (policies not network encoding) THEN THE PROBLEM HAS TO BE RAISED WITH HIGHER MANAGEMENT AND WITHOUT ADEQUATE RESPONSE, WITH THE BOARD AND SHAREHOLDERS FINALLY.

sorry for my shouting, but the legal risks to the author of this article are extremely real, and he should be immediately taking the problem seriously out of his hands.

Unilateral decisions, EVEN IF YOU IMAGINE THE ABSENCE OF LOGICAL ALTERNATIVES ABSOLVED YOU FROM RESPONSIBILITY I ASSURE YOU THAT IT WILL NOT, so please do not ever place yourself into situations like this where you are exposed to a specific liability for any resulting breach of security or loss of compliance with your employers legal regulations. Just don't take the risk. And certainly don't think that receiving moral support from your blog is any kind of indemnity. Instead it's advertising "don't hire me" as many industries will interpret the course of action. Or INACTION since you are throwing your hands up in the air, very publicly.

Edit: a word of autocorrelation, and first line for clarity
No one is proposing weak cipher suites (unless you're retroactively defining non-PFS as "weak").
But even "the numbers" can't convince the deniers. For example:

These numbers are clearly devised by "science" to deceive us. If we accept their liberal deception, a commie socialist future awaits us.

Did I do that correctly?
But it's a US thing, right ? Here in Belgium/Europe I can take out my smartphone, open my bank app, input my friend's account number and send him money right away (35 years ago you had to do it by paper, 25 years ago there were computers in the bank and now it's on the phone/tablet/web browser). Of course it's really going from one bank to the other so it's not p2p but the UX is as smooth.
And technically, Venmo was acquired by Braintree, which was subsequently acquired by PayPal.
I agree that there is a ton of misinformation floating around on the internet. Even legitimate nutritional research is notoriously difficult to conduct well. As you say, almost every diet has its benefits and supporting evidence. You will have people who claim that mostly vegetarian diets are best, and cite the Okinawans. Then you'll have the paleo crowd, who claims that you don't need fruits/vegetables at all and cite the Maasai. I think this comment pretty much sums it up: https://news.ycombinator.com/item?id=14813840.

If I were you, I'd steer clear of any sites that talk about 'toxins', 'detox', 'cleanses', or anything else like that as it's likely to be junk science. Juice cleanses can be particularly hazardous (I am honestly baffled that anybody would think drinking a ton of sugary juice is healthy). I was going to say look for articles that cite their sources, but even the medical literature can be cherry picked to support any hypothesis.

We still have a long way to go before we have nutritional advice that 1. Is actually correct, meaning it's heavily supported by scientific research and has been shown to work and 2. Is accepted mainstream. Until then, I think everyone can at least agree on a few things:

1. Don't eat sugar. Yes, natural alternatives like honey or agave are also sugar.

2. Don't eat refined, processed carbohydrates.

3. Don't eat trans fats.

I think correcting those will eliminate the majority of most peoples diet-related health issues. Everything else pales in comparison.
But the point of a currency is to be a stable and widely accepted medium of exchange. Forking undermines both of those goals.

If the US dollar forked, or an EU country left the Euro, it would widely be considered a disaster and a failure of politics and governance. Why should bitcoin be held to a different standard?
Venmo was acquired by Braintree in 2012. Then Paypal acquired Braintree in 2013.
I don't use this app and this article kind of explains why. If I go to dinner with friends, or anything, I'd rather pick up the check than worry about splitting it. The next time, they'll pickup the tab, and so forth. That's what friends do. I don't know if I'd want to go out with someone who is going to bill me for it later, or wants to use an app to split things up. For me it just makes things superficial, awkward, and distant.
I think Java would be a better second language than Ruby. It is radically different from JS despite the name and is incredibly useful to know due to its wide usage. It also serves as one or the lingua francas of the CS community (alongside C of course).

Not that I think Java is a pleasant language. It is quite a monstrosity in terms of syntax and verbosity, but that doesn't mean it isn't useful to know.

While I don't know enough about metal detectors to know how sensitive they are, I suspect someone has looked into it because there would be a lot of money to be made/saved if you could, for example, use a detector to confidently rule out metal fragments in the eyes. Bear in mind these fragments are <1 mm, and if you are wrong and the powerful magnet moves it even a couple mm you could blind a person or worse!

Geologist Peter Ward fears too little CO2 in a future Earth. Below 100 ppm photosynthesis ceases. Plants and animals all die. Only alternative energy organism survive.

Earth likely began with 50% CO2 (like Mars and Venus). By the time life emerged from thebsea is was only a couple percent; just 0.04% (400 ppm) now. During ice age advances its been as low as 180 ppm.

As the Earth cools off, there will be less plate tectonics and volconism to replenish CO2. Ward predicts a half billion years or less for the CO2 apocalypse. If there still is sentient life then, there is an easy remedy. 98% of near surface carbon is in limestone. Just burn enough limestone (as we currently do for cement manufacture).
You make a good point. If things were handled beforehand, such that one person says let's go out and split everything, I've got this app that will do it for us, then it takes that awkwardness off, and I think is more friendlier. It's the before-hand planning, versus the afterward billing...
They fail to consider that venmo and other simple cash transfer applications lower the barrier to payment of items down to the penny. Time isn't free and I would be annoyed if a friend demanded I reimburse down to the penny for something in hard cash. Asking for me to type a number into an app is so easy it's petty to worry about those pennies and a waste of time. What a ridiculous article.
It's the first sentence of the article, which can often be used as an alternative title, though obviously in this case the baitiness is so strong that the title itself becomes the story. In such cases it's better to look for a representative phrase from the article text that's both accurate and neutral. I've changed the title above to one of those.

On a side note, why expose ALL users to legacy TLS ciphersuites to support a small number of users? It would be nice if there was a way to send legacy browsers and ciphersuites to

legacybrowser.example.com

I don't know of a clean way to do that and not expose all users to the bad suites. If future versions of HTTP could encode a retry url on connection negotiation it would definitely help.

Cow. Singular.

The objections to this oversimplified reasoning usually point to the fact that, among other things, there's a documented rise in obesity among animals as well, across a variety of situations (feral rats, lab primates, domestic pets). Lab primates aren't eating out more or getting less PE in schools, which suggests the possibility of an environmental factor[1].

> particularly deep fried foods.

This is a very early-1990s understanding of nutrition. The low-fat recommendations pushed by the USDA and followed to a large degree by American consumers didn't do anything to halt the obesity rise, because excess dietary fat isn't nearly as bad for you as excess processed carbs/sugar.

I've been the latter type in the early stage of a startup, and even though I strongly believe in my more cautious approach to programming, in general, in hindsight I feel that I should've abandoned that caution or that they would've been better of with another programmer.

Thankfully I'm pretty sure the startup would've failed no matter what, so I don't feel too guilty about it. But it taught me a valuable lesson.

That article has a funnier lead. Offering a glass of wine in your own home, then billing for it afterward. That person was probably an asshole before venmo existed.
You're not doing too well regarding that either it seems.

I already tried to guard against the "no true scotsman" reflexive replies in my answer above, but to no avail. That there were many different socialist faction, and among them many non-authoritarian, is not revisionism, but available to read about for anyone that want to learn about the history of the Russian revolution. Alexander Berkman even published a diary in 1922 after fleeing Russia detailing the early years of the revolution and the totalitarian betrayal of the Bolsheviks.

This is the last few paragraphs to illustrate the point:

"Gray are the passing days. One by one the embers of hope have died out. Terror and despotism have crushed the life born in October. The slogans of the Revolution are foresworn, its ideals stifled in the blood of the people. The breath of yesterday is dooming millions to death; the shadow of today hangs like a black pall over the country. Dictatorship is trampling the masses under foot. The Revolution is dead; its spirit cries in the wilderness.

High time the truth about the Bolsheviki were told. The whited sepulcher must be unmasked, the clay feet of the fetish beguiling the international proletariat to fatal will o’ the wisps exposed. The Bolshevik myth must be destroyed.

I have decided to leave, Russia."

"If you are not embarrassed by the first version of your product, you’ve launched too late."

Please check it out and if you have feedback of find bugs please feel free to shoot me a message.
Hong Kong automated-sushi restaurant: An attempt to not interact with any humans
Might be a cultural thing? I have friends that have your point of view, and others where every meal out is a communal experience (everyone chips in, but everyone can eat every dish) even if the restaurant is not set up that way.
I was shocked by the inability of restaurants (literally their policy) in California to do individual bills. I still can't understand why it's this way... The only reason I used Venmo was for that.
Agreed.

I think it's simple common courtesy that the person extending the invite picks up the check.

As a data point, I started actual-programming in Perl 15 years ago, started on Rails about 10 years ago, and am now taking Java classes to get some interview-question fundamentals under my belt, since Rails is historically a recovery path for Java programmers. I don't know how it works the other way around, but for me Java has been pretty easy after writing Ruby for some years.

Much more importantly, however big a number "962,000 tons" sounds like, the ocean is vast, on a whole different scale from anything amount of water humans can manipulate directly.

Written out in full, that's 1,400,000,000,000,000,000. 962,000 is roughly 0.7 parts per trillion of that.
