This behavior plus their own internal social credit system to rate all Chinese citizens. Sadly, some American companies are embracing this. I remember that one company that tried this nonsens, Klout, I believe it was. What rubbish. The human variables are almost limitless. To shoehorn, pigeon hole, whatever people into a set number of variables is simply evil and smacks of an utter desire to control. I can understand the Chinese doing it. They have always had a heavy hand on their own. This tends to be an Asian constant with regard to governments. Even the Japanese are like this. I lived there for three years and noticed it almost immediately. All foreigners must immediately register themselves with the police. You are ALWAYS an outsider. ALWAYS. You are referred to as "gaijin", literally outsider/foreigner, often to your face. There are estblishments aplenty that literally have signs in the windows stating, "No Gaijin". One gets a taste of what black people in America got back in the first half of the 20th century.

I'm worried about the social credit nonsense taking off again. Some think that here in the West we are going to go cashless quicker than previously thought. I will hold out as long as possible. People have the right to buy and sell anonymously.
I think they are independent, I never took stats but took calculus in high school :)

Just seemed surprised that OP seemed to imply his high school offered only two courses... Algebra and calculus.

Mine offered algebra 1,2, stats 1,2 geometry, trigonometry, Calc 1 and 2.

Of course also pre algebra if you didnt take that in middle school...

i'm not aware of any left-leaning readers who want renewables to succeed because of their lower costs. the point is to reduce environmental impact and externalities that the fossil fuel industry simply chooses to ignore. even if the burden of upfront cost must be borne by taxpayers, it's no different than simply taking into account all factors of power generation using existing infrastructure and methods.
I wonder whether this HR sensor would be any different from the Fitbit sensor which causes me pain in about 30 minutes of wearing.

I belong to the select group of people who's having issues with HR sensors on their skin.

I support them not being allowed ever. But just like the totally ineffective body scanners at airports, too much money has been sunk in for officers not to use them.

No one actually cares about the sunk cost fallacy.

A note to the poor students, whom are doing terribly in high school, but are trying.

You can go to a community college, and in two semesters, make up any deficiencies you missed in high school.

If I had a do over, I would have gone to a community college during my last year in high school. I belive most students are given this option.

I suffered through high school on so many levels.

I don't like the way the different schools presented the information either. Yes--I went to three high schools. The last one kinda got it right, but it was too late for myself.

I'm not sure that's a good metric of overall literacy levels in the country. Additionally, I think Soviet-era education, which expired around 2002, always stacked up pretty well to other leading countries.

I agree, though maybe as a “Raspberry Pi Pro” or “Plus” model.

(Aside from that, I’d really like if all models had a serial console over USB, and perhaps a small amount of built-in flash memory to avoid the need for a MicroSD card in some cases)
It's not illegal (in the US in most jurisdictions, not a lawyer so check before you buy) to own one. In fact, they are sold to private entities all the time, mostly event venues. You can even buy one right now on eBay:

Using it, however, would likely run afoul with local noise ordinances.

I learned electronics before computers (my father was an electronics engineer at the time) and I was more or less taught Turing (intuitively) on a hardware level. So the idea that anything is possible and their is no such thing as magic when it comes to computers (modern ones included) made me keep trying because I knew it had to be possible on the gate level so it was just a matter of trying. When I still had an Msx, my friends where getting Amigas with much better capabilities. I knew that, basically, my computer could do the same: by that time I was well aware of math and algorithms, so I was able to code up ‘real 3d’ but it was so slow that my poor system had to stand there all night to calculate a rotating cube and put it into screen 5 buffers. Now that is all silly stuff, however, it did make me remember my whole carreer that there is no magic. Something which some people who learn high level only, do not seem to have. They actually seem to believe that the provided abstraction (by libraries or language) is the limit to working the machine.

All it takes is one cop who doesn't give a shit to abuse the system.
The system works for all groups. Russian-Americans outperform Russians. Nigerian-Americans outperform Nigerians. And so on.

There is ultimately a problem of the students involved that is not going to change on the scale of a single generation or two. Across multiple generations of concerted effort, who knows. But ignoring what might be 200 years from now the American education system actually works pretty well.
Put another way, this is an example of standard Google strategy: defend and control the approaches to the advertising river of gold.

Chrome was itself just such an investment. By controlling a major browser (eventually, the dominant browser), they can prevent Mozilla or Microsoft from cutting them out.

Now they want to prevent the increasing pool of ad blockers from freezing out adsense. Happily for Google, this means that advertisers will prioritise advertising through them, as they will only be guaranteed to show up in Chrome if they use adsense.

Their next step will be to bundle Contributor with Chrome. Again, by happy coincidence, this blocks out anyone else from getting a good run at microsubscription. Last I checked, the design is intended to be revenue-neutral for Google.

Disclosure: I have been working on a business, Robojar, intended to remove advertising and bypass paywalls in exchange for microsubscriptions. Google have a very similar model in Contributor.
Is the home page supposed to contain placeholder like phrases? Such as:

>Mention that having (photographer) developers as part of the target audience is good for understanding the real world problems, challenges, and workflows.

>Something about capability - highlight about some big important features! Maybe mention flexibility here (ease of writing new modules).

>Something about community, mailing list, maybe discuss forum, and the Flickr page? Number of contributors (indicate health of the project and users). Some other metric of vitality of the community (possibly how to get involved)?
I don't think example with photosynthesis suggests anything here. Naming and describing are different things. You can certainly name verbs in J, like functions in other languages, and get the code both shorter and easier to understand, because it would be distracting to always read the long definition. I think more people actually prefer former almost always, except when defining what that the photosynthesis is.
The problem isn't with the ideal scenario, the issue is when systems fail or are used outside of the ideal scenario. Generally this will be in a muzzling and controlling capacity when it comes to surveillance.

Interestingly merely paranoia of surveillance results in self muzzling and self imposed restrictions.

In the end the results are not conducive for societies progress.
Those are not transaction fees the buyer/carrier of cash deals with. It's a problem for the merchant and bank.
That's like asking, "what's the difference between the f22 and its sales brochure?" Not trying to be mean, but I don't understand the comparison. They are wholly different in nature.

Engineering takes a desired outcome in the physical or virtual world and, using principals of math(computer science), physics and chemistry, reduced to reliable functional mechanisms aggregated in a logical fashion, constructs a device that produces on demand the desired outcome.

Marketing, on the other hand, takes a desired outcome in sales and, using the powers of persuasion, produces the desired outcome of greater sales ( I suppose).

so,

engineering ===> math, physics, chemistry.

marketing ===> persuasion.
I really agree with this. Specifically, American politics, although technically democratic, is not representational. The US elections are first past the post, where as Australia's is order of preference with instant runoff (you literally cannot throw your vote away) and New Zealand's is MMP (where 50% of Parliament gets equal representation based on party preference and the other 50% get the majority vote).

Also, American preferences don't reflect policy. I did a video on a paper/publication that goes over this:

http://fightthefuture.org/videos/does-voting-make-a-differen...

Maine recently voted for ranked voting, and there are groups like Represent.us that are working to enact anti-corruption legislation at the local and state levels; knowing that anything at the Federal level simply won't pass today. We need new officials elected at the lower echelons under anti-corruption rules and for those rules to then propagate up. It's a very uphill battle considering the amount of power and money to prevent it from happening.
This is completely true, I don't know who would downvote it, though every time I've been critical of the censorship and propoganda by Bitcoin core I seem to get upvoted slowly and downvoted rapidly.

>They are around $50 per transaction now.

Pending transactions with anything above 140 satoshis per byte are currently clearing, as you can see here:

https://jochen-hoenicke.de/queue/#2d

The average bitcoin transaction is around 250 bytes, which means transaction fees in the area of 0.00025BTC and up are clearing in half an hour or less. That's about $4.

Lets keep the hyperbole to a minimum, please?

P.S. As you can see by mousing over that chart a bit, there /are/ a lot of people paying as much as $50 for a transaction. These people are sometimes morons, but more likely they are transacting on exchanges where they have to use predefined fees instead of setting them themselves. This is why it's important to use your own wallet instead of a web wallet. It lets you control these kinds of things.

P.P.S If you set those charts to 6 months you'll see some interesting patterns start to show up. Speculation on what's causing them is left as an exercise for the reader.
Ask HN: What similarities might the crypto market have with the dot com bubble?
I was too young to remember the dot com bubble when it happened.

All I know is that a friend's dad almost lost their house when Cisco's price collapsed.

But I have been following the crypto markets very closely over the past few years.

We saw a very strange move about a week ago where almost every single coin across the board increased substantially in it's USD valuation.

And I have no idea what to make of it. Surely every single coin across the board did not increase in value overnight.

Are there any similarities at all between the dot com bubble and the crypto bubble that you can see?
Yeah, it's probable that a couple of teams are less stellar than others, they can probably work it out though

It would be interesting to know about some companies that don't get to Demo day or that doesn't put out a great presentation
It’s true, but by the same token it is subtle makeup that wouldn’t even begin to fool facial recognition, even if they don’t use Near-IR/UV. Do you think you could toe that line of fooling the camera and the human? If so, I’ll buy it, as I said you’re experienced in this field and I’m not.
The Sino nations completely game these tests. Japan is legit. The Baltics are legit. The high entries for China et al are total nonsense and should be struck from the list. They game who takes the test, and it's not tightly observed.
As of about 3 months ago, software support for the ESP32 was incredibly lacking. Many very important ESP8266 libraries were incompatible with the ESP32. I ended up having to switch chips mid project because I simply didn't have time (or the skills) to write the code for a modern networking stack from scratch. That being said, the ESP32 has incredible hardware.
I work in investments, and I make More Than You Know, by Michael Maubossin, required reading. He does an excellent job synthesizing information across fields. I highly recommend it for anybody interested in diving into the field of mental models. It is a book with many citations, so an avid reader will be served well by this book as a launchpad for more learning.

The Impact of Media Censorship: Evidence from a Field Experiment in China [pdf]
I'll try to explain my reasoning, then.

If Netflix and other very profitable companies are, as I'm told, contributing in both code and money to FreeBSD, and if I'm also being asked to donate, then the contributions from said corporations are obviously not enough to cover the costs of FreeBSD development.

Since I pay for Netflix, why should I double-pay by donating to FreeBSD? Seems to me that Netflix should be digging a little deeper into their pockets.

I don't understand your point re: Windows. If companies are paying for Windows, then Microsoft is receiving a payment which they have presumably set at a level they deem sufficient to support continuing development of Windows and other projects. I see no parallel to my point about FreeBSD other than the fact that both are operating systems.
This captures what is Banks interest in blockchain in a nutshell

> Banks want to use Blockchain as a more reliable alternative to SWIFT it won’t be doing actual account settlements which in your case you mentioned corresponding banking.

> That said many of the more progressive institutions stopped calling it Blockchain a while ago they all are talking about distributed ledgers, hyper ledger and the likes are being either used or piloted by many institutions.
For what it's worth here's a citation proving counter to the statement...I stole from another commenter.

As someone who grew up in a poor immigrant family where the first generation was uneducated and spoke no English...I always find it insulting when low education is attributed to not having money. Not just myself as a counter anecdote, but 10 out of 11 of us second generation have college degrees and doing pretty darn well for ourselves . #11 is still in college.
Quite right. Israel's El Al simply profiles everyone that flies and by doing so they obviate the need to use stupid, expensive equipment that does nothing other than bottleneck airports and cause frustration. The Israelis are the best in the world at what they do regarding air security. The West has considered using the same techniques and they likely should. I'm not opposed to profiling if the person fits the profile. Better profiling than dead innocents. People do not have the right to not be offended. I get the heavy hand for some reason every time I fly and I'm literally the grey man, but I understand and go along with it. I'm also squeeky clean from a legal standpoint.
>bitcoin is a research facility, not a product

So now it's not a currency, and it's not an store of value, it's just a research project.

It feels a tad bit irresponsible for the bitcoin community to have gone around advertising this as the currency (later store of value) of the future, while apparently not knowing if scaling to worldwide levels would even be possible.
Can't say, but it actually seems pretty forced, like a joke. All of those placeholders actually link to the resources they'd want. I'd guess it's a poke at regular start-up style "We are awesome because X" statements on their home page.
Bitcoin’s boom is a boon for extremist groups
Even if she won, she was still the Secretary of State that gave us more predator drones, more bombing and served under a president that spent every day at work (the first president in history).

I feel like people don't realize the corruption is pretty equal between both candidates/parties, they just toss a few pandering policies here and there to get people angry, or spin things differently.

Warranties are different because though they also depend on non-utilization, the defects they cover are generally likely to occur at some point (the guarantor is just hoping it will be after your warranty expires), and consequently higher utilization rates are expected.

Insurance is based on the assumption that only an extremely small number of insured persons will ever make [significant] claims against the policy; insurance is for expensive potentialities that are very unlikely. The entire industry and regulatory framework is structured around that assumption because that is what the word "insurance" means in all contexts outside of health care.

The problem is that pretty much everyone is going to need significant medical care at some point in their life, certainly as they age into their senior years if not earlier.

Would you buy a "health maintenance plan" under the stipulations of health insurance policies, which are basically "Pay us a lot of money, and we'll make some farcically big numbers look smaller for you, but you'll still probably owe a lot of money; we won't know how much until you already owe it"? Of course not.

The racket we call the American health system can only exist by masquerading as "insurance".
You can start with running your JSON data (or whatever serialization format that you choose) through NaCl/libsodium's crypto_secretbox() and you already get more than what JWT offers by default.

It still doesn't include everything you need of course: at the very least you'll still need to implement expiry validation and some token revocation mechanism. But you actually get more value out of the box than you get with a JWT library: your token content is encrypted, your using a solid crypto library and you don't have to mess around with any knob to secure your implementation.

It doesn't offer support for hot-swapping crypto algorithms, but for what it's worth, cryptographic agility is the root cause of many issues we had with TLS in the past[1].

If you end up needing both symmetric and asymmetric cryptography in your tokens, you better treat them as two different types of tokens, because they usually are. I think tptacek already said, but asymmetric crypto is rarely interchangeable with symmetric crypto - you usually use them in very different cases.

I don't know much about radio, so your question had me stumped for a second, and the other replies didn't help me much. Here's my explanation:

Some celestial bodies like the moons of Jupiter, are too dim for us to see, because the amount of light that hits our pupils is too small for our retina to react to. But the light from the moons isn't pointed directly at our pupils, it goes in all directions. If the area of our pupils were twice as large as it is, we would be getting twice as much light from Jupiter's moons — and everything else (except a laser pointed at your eye, please don't point lasers at people's eyes). Telescopes work by being a HUGE pupil, collecting all the light from a wide area and pointing it all right at our pupils (that's not the only thing they do, but it's an important part).

An antenna is like a pupil, and a satellite dish, or this piece of aluminum foil, are like a telescope. Some of the signal from your laptop in the bedroom goes and hits the antenna with a weak signal. A lot more of the signal misses the antenna and hits the foil, and then gets reflected where some more hits the antenna (since the foil was curved, more of the signal hits the antenna on the rebound than on the first pass).
Thanks for elaborating.

> You claim that one device in particular you happened to own has a certain characteristic failure, yet offer no discussion of the n on the issue, distribution, nor anything else really except “well I felt this way”

What I wrote: "For option [c], it’s important to view this hardware crash as a problem unique to these phones. ... Admittedly, I don’t know that it’s unique to this hardware."

I've essentially invited anyone with better knowledge to knock down my posit, while giving my reasoning with the facts that I know.

> Then you claim that thermal throttling is somehow unique to Apple yet every device these days does such thermal management

What I wrote: "unlike any rechargeable device I’ve ever owned — the iPhone 6 and 6+ suffered hardware resets (crashes) when their batteries drop below a certain output"

For starters, this isn't about thermals, as far as I understand the issue Apple was trying to solve. And what I described as unique to the iPhone 6/6s is that the hardware crashes as the battery health degrades. I've owned a lot of rechargeable devices over the years. When their batteries degrade, the battery doesn't last as long. I don't recall that any of them began to experience crashes.

> And when you look at the trade shipping any product, and what defects are considered acceptable... you write as if you have zero experience or visibility into any of these issues.

There's a lot we don't know about this iPhone 6 + battery + slowdown, like at what battery health does Apple begin to slow down phones, how long before users reach that battery health (within warranty?), how can users identify if they're affected by this, and how many devices are actually affected. It is entirely possible that the problem is overstated, and not widespread. It's possible that nearly every device is affected within warranty. Probably somewhere in between.

But none of that is my point. My point is that -- on the assumption that this is a hardware/software design problem unique to these devices, and I invite you to kill this assumption -- resolving the crashing problem by slowing down devices is hostile in that it penalizes consumers for a problem Apple created.
