I’ve had the opposite experience. After finishing grad school and working in industry for a long time now, applying ML to computer vision, NLP, causal inference and quant finance for production systems, the vast, vast majority of problems are such that the training and test set are defined by very precise business operating constraints and it’s known with a high degree of certainty that future examples to which the model is required to generalize will also be from the same distribution reflected in model training, and any differences are so minor as to be practically ignorable all the time, and requiring really special evidence to show the super rare cases when it cannot be ignored.

(Those cases also are most often just solved by collecting new/ more training & testing data and re-training / fine-tuning / calibrating the model to some slight shift in the distribution, and require no formal modeling techniques related to tricky generalization distribution differences).

This has been true across commercial ML products or services at large tech companies, small startups, quant finance firms, defense research labs, and academic labs. Across projects ranging from face recognition, high-traffic search engine and related services like machine translation, trending models, search ranking, dimensionality reduction models in time series forecasting, reverse image search, audio similarity models, advertising models, and many more.

It just turns out that in industry, the problems that have meaningful utility to the business are almost always defined by intrinsic constraints that nearly guarantee there won’t be a meaningful difference in the distribution of future prediction-time examples compared with training & testing distribution.

why not get a dedicated device?

For the same reason I don't want to carry a big heavy DSLR around with me, because there's a limited number of devices I want to lug around.

I ditched the DSLR years ago (yes, it took great photos, but not enough to make it worth the hassle). Though I still bring a pocket sized camera with me when I travel because my smartphone still can't compete with a big sensor and an optical zoom.

While a dedicated MP3 player is small (to be honest, I didn't even know they were still made), it's just one more thing to keep track of and keep charged up.

Ask HN: What (emerging) web standards are important for HTTP APIs in 2018?
I'm working on a HTTP API, and as much as high quality library code in Django Rest Framework has been able to shape the implementation, there are always questions and points of debate over things like error response shape.

Turns out, there's an RFC for that, RFC7807 describes the schema for a JSON problems/error object!

What are the important to follow RFCs and emerging web standards for HTTP APIs? How can I determine which of two possibly competing standards is more mature, e.g. rfc7396 & rfc6902 for JSON Patch...
There is no question about other nationalities on the visa application form?

What do you think will be the long-term story for Scala.js, with WebAssembly becoming mainstream, and current WASM shortcommings (e.g. GC and concurrency) out of the way? Do you expect Scala.js folding back into Scala?

Other question, does Scala's moving towards DOT-based foundations (e.g. dotty) affect Scala.js?

It's still a solution in search of a problem. In a marketplace, there are two fundamental fears to be addressed: the seller's fear that the customer will not pay the money for the goods, and the customer's fear that the seller will not actually provide the goods. The classic solution to this problem is escrow, where the seller and the customer both agree on a trusted third party who will hold the customer's money until the seller delivers the goods.

In modern times, credit cards and the like provide an adequate solution the problem (there's definitely strong dislike over things like fees, though). Early digital currencies failed because they weren't trustworthy as third parties, or they failed to gain a wide enough userbase to keep fees low. But it's not like they all failed--PayPal is with us today. Bitcoin and other cryptocurrencies suffer as a payment method in that they don't solve the customer's problem, particularly in cases like ransomware where there is strong reason to doubt the seller's ability to deliver.
Disclaimer: I've co-founded a company building cryptographic protocols for existing cryptocurrencies. I'm also a cryptocurrency security researcher.

I believe in Bitcoin and the recent developments in both cryptography and distributed systems which are underlying many cryptocurrency projects. I think the skepticism of Hn is rational, valuable to the community and often correct. The cryptocurrency space is a great space to work in, but it requires a constant investment in skepticism and critical thought. I hope Hn always remains skeptical of technology.

> The underlying technology is actually pretty worthwhile. Ethereum is providing a base layer protocol for apps that never go down, never fail, and are fully trusted.

I disagree with this statement. Ethereum DApps can fail, Ethereum can be rendered unavailable via: scalability issues, forks, bugs or failures in the P2P network. Furthermore the additional infrastructure that many DApps rely on can fail as well. Ethereum is not a solution for achieving high-availability, high-availability is probably harder to achieve with a DApp. Ethereum is a solution for building and managing assets outside the control of a single party or company. This intentional loss of control comes with many costs and does not provide universal business benefits.

Strawman much?

GP comment was clearly directed in support of a decentralized "winning tech will win without the need and costs of centralized government planning".

My Nissan LEAF is wildly cheaper (~40-70% cheaper) to operate per-mile than my wife's very sensible Honda CR-V. Her car is wildly cheaper all-in because it's a 2005 vs the 2015 LEAF. Give it 5 more years for the common electrics to be readily and plentifully available on the used market and this will even out. The electric cars are already coming. Quickly.

This is all happening without the need for a government program to guarantee a job with the government for anyone who wants one as the article pitches as an essential part of the "Green New Deal". (What does a government job have to do with sea level rise either?)
> If one could voluntarily embrace this process, would this make opioids less necessary and/or desirable?

It certainly would, but "embracing" the process of pain is an enormous mental and physical challenge.

Entire religions, for example, are devoted to separating the mind from the experience of the body. But this takes years of conscious effort.
I find it horrific and psychotic that Iranian citizens must bear the random and illogical attacks of the USA against their basic lives. We aren't talking about banking or visas anymore, but merely publishing a paper.

As for what can be done about this? If actual political change can't be achieved in the US, then the world must change all of its systems to avoid hegemonic rage.

Sadly, though this is technically possible [1], it seems that one does not gain reputation by using non-traditional publishing venues.

From the linked article: Components are more powerful, but they have to render some UI. This makes them inconvenient for sharing non-visual logic. This is how we end up with complex patterns like render props and higher-order components.

But this is a problem with how some applications are using React, where they make everything a React component. You don't need to make everything a React component. In the MVC model only things that put stuff on the screen need to be React components. You are saying Hooks are better than controllers--and maybe they are. But when the problem is stated as in the above paragraph, then it is not obvious that Hooks are the solution. Maybe the problem should be stated better.
Well, thanks to the likes of Julius and Ethel Rosenberg the Russians were no doubt able to save a helluva lot of time and money.
Not so long ago widely used audio codecs (the actual ADC/DAC part in the PC) had big problems with idle tones at low signal levels (which were simply gated off at silence, otherwise you would have gotten constant, looping artifacts). I managed to reproduce over 100 % THD+N with my old Thinkpad X200, i.e. more, very clearly audible, noise and artifacts than signal.

This is a separate issue though from the usually high output noise floor and poor isolation from other components, e.g. many complaints about many makes and models where CPU/GPU or even disk activity will induce audible pulse noises in the heaphone outputs or speakers.
There's a lot of smart and well-off people on HN that are not tinkerers. This article scratches the itch for tinkerers who could envision walking through the described steps themselves. On the flip side, this would be a non-problem to others, simply purchase the other thing and stop griping about manufacturer's cent-saving BOM hacks.

Anyway, if the problem becomes big enough, some individual/organization will see the market opportunity somewhere, hopefully.

I guess I agree that the legislation should be simple. For example legislation that ban carbon pollution within certain industries by a certain date. Say, by 2035 for electricity, 2045 for agriculture. That would really set things in motion wouldn't it.

It would make a lot of old folks mad, but the younger generation would know which skills to build for the new economy.

You can't print a concrete house in a hour. It would collapse. Also, in general, the slower concrete cures the stronger it is - to the point where attempts to have it cure faster will destroy its compressive strength. Concrete walls should remain in forms at least one week and far better for two, and be wetted continuously during that period. 3d printing concrete needs a massive breakthrough in 2500 year old curing technology or it's a death wish.
Yes some of it, most of it is from the official government websites
Stories like these are going to become increasingly common. Chinese companies are completely opaque and the SEC cannot easily audit Chinese companies. It's easy to rip off Western investors as the power structures lean towards Chinese citizens, always. Their entire business structure is built with the Chinese first and everyone else second.

I think it was only trivial in hindsight. Scientific publishing is rife with articles the reveal a problem without offering a solution; to expect one seems outright weird.
Super timely as I just passed my tech and am studying for my general. It’s been a very long time since I undertook a learning endeavor that was not related to my profession. Really enjoying the process.

I’d encourage anyone interested to take a practice exam for a technician license. I was shocked at how much I picked up over the years via osmosis and got pretty close to passing the first practice test I took.

DAI, like other stablecoins, isn't really all that stable - right now it costs about $1.02 to buy $1 worth. And, it's frequently been over 5% away from $1: https://coinmarketcap.com/currencies/dai/#charts

Most "stable" coins are trading at over $1 right now, presumably as people try to flee sinking cryptocurrencies and have no practical and/or legal means to turn them into real money.

The v1 droid, with the sliding keyboard. I would buy again in an instant if a comparable phone existed. It was _tiny_ too, and indestructible. Loved that phone.

Software updates not what you requested, but from a featureset perspective, other than "turning up the dials" I feel like i'm paying more for less with every upgrade, although that may be blamed in part by app/web bloat.

(This post is an expression of a broad similar gripe I have across much of tech, e.g. within chat software; we peaked with desktop gchat/pidgin >decade ago, the hell have we been doing since then. Discord is a great evolutionary branch but it doesn't fill the original niche)

Edit: As a sister post says, the E4 isn't a terrible alternative, but I find it to be bigger, more finniky, and less functional than the OG droid (currently using an E4). Good price point though.

I spent the last 6 months trying to build [Visalist](https://visalist.io). Now your quest for tension free visa requirements research is over.

Here's why I made this web app: A year back I became a digital nomad and started traveling. I wanted to visit all the countries that I fancied. Soon I realized that you need a visa to most of these countries, few have VOA(Visa on Arrival) and for others, you have to get it through their embassy in your home country(in my case India). So now I wanted to see the countries I could go without waiting for 3 weeks to get a visa, did some research. After few blogs and websites finally got the list. Traveled to a new country. After few months I wanted to go to another country. I had to do the same search, couldn't find the old one, found a new site which had more countries offering VOA. One of my friends told me that when he researching for Vietnam visa, he found almost 10 websites with .gov and it was really confusing. Many blogs don't have links to official websites of embassies.

To summarize the problems:
* No aggregated info of visa related info shown in a useful way.
* Most of the existing blogs and website has very less info and are usually outdated.
* Lot of research is needed even to go to a single country and this needs to be done every single time.
* Difficult to find the official website and data on many websites is outdated.
* Pay more than required money to visa agent's

So I took the matter into my own hands and decided to aggregate this info, organize and present it in a useful way to the user and so VisaList was born. While I was talking to my friends about this, I realized many people wanted something similar from a long time. So what this has is
* A simple way to find the basic requirements for all the countries you want to travel
* Simplified visa requirements like visa-free, visa on arrival, visa not required, evisa, visa required and visa refused (Yes! For North Korea)
* A simple map color-coded with visa requirements across the world so you can easily see which countries around you can easily travel to
* Visa Requirement details like duration, documents checklist and other requirements for the stay
* Which is the official website for that information

I coded, designed and built Visa List using VueJS with NuxtJS for the frontend, MySQL for backend using Golang. I was originally an android developer and learned these just to build Visa List.

I believe every person who wants to explore the world around them and would have faced the problem I faced, so could find value in what I have built. So I would love to know what you think of this and would be more than happy to hear your suggestions and feature requests. Let me know what you want to be added or removed or do I need to build something entirely!

Thanks
Peer reviewers are humans, there are many examples humans denying, avoiding, turning away “uncomfortable” evidence.
I agree that it's a bold title, and agree that the the collected essays probably aren't going to measure up to the historical standard. But I think this is central to Yang's thesis that the standards of behavior are different for Asians in America than they are for others.

For me, I think the title choice works because it calls attention to the fact that Asian American culture is not particularly open to the strategy of aiming really high and being likely to fail, and instead favors targeting a more modest level of success that can be attained with greater likelihood. Braggadocio and overconfidence are not considered typical traits.

Yang's title is high-risk high-reward high-likelihood-of-failure, and I do find my self surprised (in what is likely a racially biased manner) that an Asian American male would choose such a brazen title. That I have this thought (as a non-Asian Amerian) makes me suspect that Yang is on to something.
Why? The whole point of indexing is not to do that. Feel free to move your money to an active fund that tries to catch out companies with lies on financial statements.
I prefer a decentralized approach. ... Once electric car total ownership costs get low enough, then gasoline cars will be worthless scrap heaps over night. Once solar power and battery tech improves enough, it will take over very quickly.

Let's see. Capacity of a Tesla battery: 85kWh. Let's say 1m^2 of solar panel can produce 200W in good sunlight, and we'll handwave away all other conversion inefficiencies. Let's say we get 8 hours of good sunlight a day, so in a day 1m^2 of solar panel will give 1.6kWh. So with 54m^2 of solar panel, we can get 1 Tesla charge in a day. Maybe that could work outside of a city where everyone has a big backyard, or can cover the roof in solar panels, or both (I don't think my roof is anywhere near that big at least on its south-facing side, and the back is in shade). Maybe you can buffer it in a vanadium-redox battery so you can actually charge the car overnight. But with the cost and the amount of solar you need if you can only get 100W/m^2 for 4 hours a day, that's going to get real big and hence expensive. And that's when you will really need the vehicle because maybe the weather is too bad for alternatives.

Electric cars in cities are going to go on being powered by a central grid forever, basically, because physics.
