There are specific issues, mostly regarding clarity with regard to demonetization. It's all automated, and there are lots of errors.

H3H3, for example, made the video "Christian moms against dabbing" as a test for ad-friendly content, but was demonetized because of the word "Christian" in the title. It was not a controversial video, actually quite light-hearted, but the algo still triggered.

The frustration you hear/read is that many creators do understand the advertiser issues, but find nevertheless find it difficult to work with YouTube's automated systems.
Having read that, I'm not finding myself enlightened or my mind opened in the least. What was the point, other than it's hard to calculate externalities?

Argument that "it's hard" is not much of an argument at all. It does make me think that there's considerable flexibility in a "libertarian" position on externalities though.
I've been using the new Mac Pro since 2015 and it's served me will without the need for upgrade... except for one thing. The primary disk being only 256GB causes me all kinds of issues. Everything wants to install and save there and there's no simple way to offload stuff to a secondary disk, so I'm constantly moving, symlinking, etc to keep enough space free so that my computer doesn't crash. Very annoying.

This could, of course, be solved with software.
this is a good discussion: http://www.northwestsourdough.com/experiments-with-autolyse-...

the answer, as usual with baking, is it depends. Salt definitely changes the chemistry. Salt mostly stabilizes the gluten structure and makes it stronger, but it can also inhibit development of new gluten bonds somewhat, particularly when the flour is initially hydrating.

You need to experiment, try a 2 hour autolyze before adding salt for a 24 hour cold rise.

Nice to see Epics Unreal Engine 4 blueprints in there. Right now I am heavily relying on blueprints instead of c++ as I wait for some features to mature, and the interface is really growing on me. I just find it easier and faster tot prototype in.

I think a big problem (and you highlight an outcome here) is that focussing on geo political units like county boundaries which have a huge variance in both area and population is always going to be a troublesome background on which to pin statistics.

One idea might be to distort the map so each county has a size proportional to its population - quite tricky around metropolitan areas! There might be a way to aggregate adjacent counties in some way.

Depending on the raw data granularity it might be best to dispense with political boundaries and say plot based on some form of population to area measure that smears things somewhat. That would probably be fair but wont please anyone with an axe to grind (ie everyone).

You should see the statistical contortions carried out here (UK) for similar bollocks. North/South divide? - where is the middle of the UK? Who knows? Does it include Scotland, Northern Ireland and Wales? Where exactly are the Midlands? Is Wiltshire in the South West or the South? Anyway you get the idea.

You end up spending more time explaining outliers and oddities than you do focussing on the real issues (whatever they are) with these kind of maps unless they are very, very carefully and rigorously put together. A fair and rigorous map will probably please no-one 8)

Oh and another thought - if your post (sorry) zip codes are involved in the raw data then as a previous article on HN showed they don't always map very well to the boundaries they purport to cover.

Ok, so you're past claiming that "pretty much everyone in the country" has the benefit of "wide availability of cellular service that provides broadband speeds."

Well, that's progress anyhow.
And its not just causation. There are often unaccounted variables that are driving both the cause and effect and observing that decorrelates the cause and effect completely. There is some fascinating research going on on this in the field of economics. Matt Taddy, University of Chicago, Microsoft Research is doing some interesting research on this very kind of problem.
> Avoid Docker forwarded ports in production environments.

The general rule is rather "avoid Docker networking in production
environments". Docker does heavy magic to isolate programmers and operators
from details about network configuration. (A corollary: good luck with
figuring things out when it breaks or when you need any non-standard setup.)

> Ports can be easier to manage, instead of a bunch of files, when dealing with multiple processes

Using TCP port is similar to setting 0666 permissions on a directory/file. Who
cares about those ridiculous things like user and service accounts? Modern
applications don't need no stinking credentials isolation.

That's what I've been considering for sure. I'll (hopefully) always have web dev as a fallback to make some extra cash on the side if something falls through.

Thanks.
The crumple zone point in the article misses the mark. The reason why crumple zones don't exist on American railways is due to incompetent and centuries-out-of-date Federal Railroad Administration regulation. FRA insists on railcars being able to withstand 800,000 lb of pressure without deformation, the so called "buff strength" requirement. This works OK for low speed gondolas and goods vans making up the bulk of the US freight network, but doesn't work at higher speeds or when there are
passengers.

If you want to see conventional, FRA-approved "buff strength" safety tested against "crash energy management" -- a broader concept including crumple zones -- watch this video [1]. The differences are striking.

But to reiterate: don't blame crash safety on lacking technology. Blame it on bad regulation.

For what's it's worth, I never found a use for optics.

The idea is that you declare read/write optics than you then compose and reuse.

But on a web app, say, in how many places can you update a person's address?

Writing non generic code that update it in a non generic way (throw away code) is much less ceremony than defining an optic and only using it once.

>fit your worldview, and ignored all the critique around them. That's not objective science.

^This is an accurate description of western psychiatry in general, ironically, because 1) psychiatry is not objective science 2) psychiatry assumes individual deviation from society's norms is the root of disorder, rather than seriously considering the disorder of society's norms at large.

Nice read. This is something we wanted to solve for our mobile applications too but we don't get enough traffic (per article, you guys are ~100k msgs/hr) to justify the engineering time required for this.

I don't use Airbnb as often as I should but I'm wondering do you guys have data on the users who simply use text messaging on the mobile devices (or other instant messengers?).

What led to the decision to spend time optimizing mobile messaging within the Airbnb app than just finding an easier path to connect users through text messaging?
How to spot data visualisation lies
Note that anti-depressants—at least in the case of episodic depression—are supposed to be used as a crutch, not as a "management therapy." You prescribe anti-depressants to someone who can't get out of bed to see a therapist, so that they will then get out of bed to see a therapist, where the therapist can then get them over their depression. Anti-depressants are not supposed to be used "mask pain" any more than crutches are supposed to be used to "mask pain" in your leg. They're supposed to take the pressure off a thing that generates pain, so that you can work productively on making your life better (healing the leg) so that you don't need the crutch.

Though, that being said, there's also a second, less obvious thing anti-depressants do: first-line anti-depressants specifically are hard to distinguish from placebos, but that's okay because first-line antidepressants are often prescribed by doctors who believe† that a placebo is, in fact, all a person might need in order to feel better. That's why they're given out so freely: placebos are pure benefit (no risks, possible reward) so it doesn't hurt to try them before doing literally anything else.

If the person doesn't improve under first-line placebos, then the doctor will move on to figuring out what "actual" medical interventions might help.

† This approach is doctrine among psychologists, but not necessarily what your average psychiatrist/therapist/prescribing GP will be thinking about. Prescribers "out in the field" are mostly following the DSM guidelines for first-line/second-line/Nth-line treatments of depression, which just say that the first-line pharmaceutical interventions are very well-tolerated and low-risk.

I didn't say the MOST, it's among the more scientific languages. I'm not pushing for Korean patriotism, that's just your own assumptions.

> So, you're talking about the alphabet used to write the language, not the language itself. At best you've proven that Korean has a highly regular writing system. But I'd argue that the average HNer could learn to read, for example, Spanish in about two minutes.

Hangul is the writing system that is uniquely different from a latin based system like Spanish. Your argument is moot.

What's really important in this context is building something quickly. That's why GP mentioned Rails and Django; they come with many things either built in or built by community, so you can focus on building your first version quickly. To the extent that is true with other tools or frameworks, sure, go for it.
I'd be very curious to know why this is getting downvoted, and if it has anything to do with the fact that YCombinator is a hub for the 'innovators' the post (and this comment) are talking about.

Kipper BASIC / BASIC on Bails (2014)
Elm seems like an excellent choice for a small or large dev team. There's only one way to structure your app - the Elm way. As your app grows, it must still follow the Elm way and the same circle of events. For developers transitioning on to the app or different parts of it, business logic is the major hurdle and not the app structure itself. The app structure is more or less the same be it a small or large app.
I believe it is automatic, though. Some % of your Red subscription gets divvied up among your views.
Someone tell me again why we don't have public internet backbone like we do roads?
Intended? I don't think much technology is developed with long-term social impacts in mind. We're kind of careless like that. In the tech world we're only just starting to realise the importance of this, and then only because it's recently become apparent how frighteningly easy it is to reshape society with software. Most other industries' ethics stop at "don't kill people".

Predicted? It's impossible to predict perfectly. But a great many effects were predicted in one place or another - especially the negative effects. The Machine Stops, 1984, and Brave New World all deal with the themes of technologically networked society and mass visual media.
I think you're going to be waiting indefinitely then :).
> Just saying that Chinese had "moveable type" omits the technological and practical considerations that made European printing press success.

OK but just saying the Europeans had a superior printing press omits the the radical thinking and acting that made Martin Luther's doctrines a success.

Your position is like saying, baseball became America's national pass-time because of radio. Yes, radio existed and helped, but it wasn't radio broadcasts of soccer or regional hopscotch tournaments. Baseball made a particular appeal to the soul of the people and the time which soccer and hopscotch did not. The medium is not the message; content is king.
Seriously, been reading your blog this afternoon and love it man. Maybe I'll stop by in Africa next year! Hah.

I 100% agree.

Maybe I just wasn't built for the tech field, but something about sitting on the computer all day feels wrong.
I didn't look into the data, but the CDC and other agencies have policies that set values to 0 in public versions of their datasets if there is a risk of inadvertent PII disclosure. This is particularly the case with smaller cities/counties and rare diseases.
Not to mention the potential cost of missing work to go to therapy. Some people don't have PTO or a flexible schedule and getting to therapy appointments is a real pain in the ass.
Generally I would agree. But this past election cycle turned a number of things on its head -- Trump was the "innovator" and HRC clearly the "maintainer". But your point is well taken - it would be so good to get back to two parties, opposed but working together towards a better outcome.

I have the distinct idea that you have never read Popper.

http://www.iep.utm.edu/pop-sci/

"Partially in response to worries such as these, the logical empiricists’ later work abandons the verifiability criterion of meaning and instead emphasizes the importance of the empirical confirmation of scientific theories. Popper, however, argues that verification and confirmation played no role in formulating a satisfactory criterion of demarcation. Instead, Popper proposes that scientific theories are characterized by being bold in two related ways. First, scientific theories regularly disagree with accepted views of the world based on common sense or previous theoretical commitments. To an uneducated observer, for example, it may seem obvious that Earth is stationary, while the sun moves rapidly around it. However, Copernicus posited that Earth in fact revolved around the sun. In a similar way, it does not seem as though a tree and a human share a common ancestor, but this is what Darwin’s theory of evolution by natural selection claims. As Popper notes, however, this sort of boldness is not unique to scientific theories, since most mythological and metaphysical theories also make bold, counterintuitive claims about the nature of reality. For example, the accounts of world creation provided by various religions would count as bold in this sense, but this does not mean that they thereby count as scientific theories.

With this in mind, he goes on argue that scientific theories are distinguished from non-scientific theories by a second sort of boldness: they make testable claims that future observations might reveal to be false. This boldness thus amounts to a willingness to take a risk of being wrong. On Popper’s view, scientists investigating a theory make repeated, honest attempts to falsify the theory, whereas adherents of pseudoscientific or metaphysical theories routinely take measures to make the observed reality fit the predictions of the theory. Popper describes his proposal as follows:@

Thus my proposal was, and is, that it is this second boldness, together with the readiness to look for tests and refutations, which distinguished “empirical” science from non-science, and especially from pre-scientific myths and metaphysics. (1974, pp. 980-981)

In other places, Popper calls attention to the fact that scientific theories are characterized by possessing potential falsifiers—that is, that they make claims about the world that might be discovered to be false. If these claims are, in fact, found to be false, then the theory as a whole is said to be falsified. Non-scientific theories, by contrast, do not have any such potential falsifiers—there is literally no possible observation that could serve to falsify these theories."

From this perspective you are confusing "scientific" with "empirical".
Thanks to everyone for their heartfelt responses and interesting viewpoints! Some have pushed back regarding the notion of serotonin imbalance. I would point you to literature that strongly challenges the idea of straightforward neurochemical imbalance as the cause of depression. This is a good place to start: http://kellybroganmd.com/depression-serotonin/

From that article:

> "The most applicable analogy is that of the woman with social phobia who finds that drinking two cocktails eases her symptoms. One could imagine, how, in a 6 week randomized trial, this “treatment” could be found efficacious and recommended for daily use and even prevention of symptoms. How her withdrawal symptoms after 10 years of daily compliance could lead those around her to believe that she “needed” the alcohol to correct an imbalance. This analogy is all too close to the truth."

I believed in the chemical imbalance theory for many years, but now I am persuaded that it's more marketing slogan than scientific reality. This is not to say that antidepressants cannot have beneficial effects. Just that it's not clear that they are correcting any naturally occurring imbalance.

As far as the interesting point that emotions and neurochemical brain states may be equivalent, I grant that this may be true. I guess it was more my way of referring to two approaches to emotional problems: the first, which sees the problems originating in the brain chemistry, internalizing the dysfunction within the sufferer. The second, which sees the brain chemistry mostly as a reaction to the life and environment of the sufferer, wherein the true dysfunction lies. This points people in the direction of their relationships, the congruence of their values and choices, their life philosophy, etc. which I find a more productive pursuit.
I'm really hoping for YouTube (Google) vs. Twitch (Amazon) competition. YouTube is clearly moving into Twitch's market, and there are signs that Twitch is looking to expand into non-streaming content.
E.P.A. Dismisses Academic Scientists from Major Scientific Review Board
This boils down to well-known and well-understood behaviours of energy systems, particularly at large scale.

Much of the waste is simply Carnot efficiency of thermal systems: the amount of useful energy you can extract is proportional to the (absolute) temperatures (Kelvin) of the "hot" and "cold" ends of the cycle.

For thermal electrical generation -- coal-fired plants, gas-fired turbines, oil-fired turbines or diesel generators, biomass thermal, solar thermal, or nuclear plants -- this is in the range of 30 - 45% or so. Ironically, high-temperature thermal coal achieves some of the best thermal efficiency. This doesn't mitigate its far more compelling downsides.

Direct kinetic or photovoltaic electrical generation has no thermal losses, but is subject to the efficiency constraints of the input stream: hydroelectric, wind, or solar PV.

There are additional losses in transmission (about 6%), and in electrical conversion and switching equipment ( ~<10%). The net is about a 66% energy loss in what's delivered to the electrical customer.

For transportation, you have the same Carnot efficiency limits, but given the smaller temperature differential start with a lower initial efficiency -- about 30%. There are additional losses through parasitic systems (any powered in-car features: power steering, brakes, A/C, electrical and electronics, etc.), transmission losses, tire and wind drag.

Again, all well understood and modeled, and well-behaved in large-number populations.

The Lawrence Livermore National Lab (LLNL) has done energy modelling for the United States since the 1970s, and has a set of flow diagrams (Sankey diagrams) showing flows dating to the 1950s, through the present.
