You should try cod liver oil ("tran" for Norwegians). It has been the traditional food to combat SAD in their long winters.
I've been working on a project lately that was designed by a really smart guy. It follows the OOP patterns and IoC and all of that. Trouble is you can introduce such complexity that maintenance from someone a few years later can get incredibly difficult. A lot of this code I'm working in has implicit dependencies that are really hard to trace w/o stepping through line by line. If the code was more explicit, maybe it would offend the ideologists, and maybe it wouldn't be as flexible as it is (debateable), but it sure as hell would be easier to maintain.
One idea is Bongard problems, because they are purely creative categorization, so it's interesting for AI. http://www.foundalis.com/res/bps/bpidx.htm
I'm interested in hearing an answer to this question as well.
Although I took a grad course 3 years ago that was essentially walking through the Linux kernel to understand how a kill system call works. It was a fascinating ride, but I have forgotten most of what we did.

I have read many posts from [1] related to understanding how it works in Linux. You may enjoy it.
Also, I bookmarked [2] to read later, but the later never came..

Good luck.

Ask HN: Is Coinbase down?
I was refreshing the dashboard and I saw Bitcoin trading at 18k+ and then the dashboard becomes unavailable.
This is the solution that seems sensible for me. Creating a "locker" (mudroom, just a big box, a garage... with access only to that space for Amazon and others). Granted that isn't going to be worth setting up for many people. But for those that it is it worth the bother it seems like a valuable feature (secure storage at location accessible to delivery personnel).

And that the feature also lets those that want to just to give access to their whole house seem a useful way to grow the adoption (since my guess is many more people will take this more convenient, though less secure option).
Well it helped when XCode came out with integrated clang static analysis, vs with the largely ignored lint.
Currently it stands at 250kWh per transaction. My two person household in a developed country with lots of appliances uses 6 Bitcoin transactions per year in electricity. Bitcoin eletricity uses is insanity and it's only set up to rise.

Licensing Board Admits It Can't Silence Red Light Camera Critic
Maybe it's different in US, but in UK all deliveries from Amazon are done by 3rd party companies - DPD, Hermes, Parcelforce, etc, even if the tracking website says "Amazon Logistics" - it's just a front company.
> “They couldn’t see the red light,” said Police Chief Brian DeRosier. “They kept going through the stoplights because they thought they were green.”

Uh, if they cannot see the lights, why wouldn't they treat them as 4 way stops? Instead of "HURRDURR IT MUST BE GREEN AND I COULD NOT POSSIBLY SLOW DOWN FOR SAFETY"
Vertical tabs in tree structure is currently the best way to use web, especially when you pair it with auto-unloading of inactive tabs. I'm also disappointed that nothing better appeared in last few years. Developers seem to be extremely conservative about UI. With WASM it seems that browsers will take over most of OS functionality and the UI is getting in the way.

IMO we should ditch tabs, bookmarks and history. They all implement the same thing - a way to reach a place you've visited before. And they all require to be micromanaged in specific ways. The browser already knows which sites I've visited recently, and all the backtracking and branching I did. This information could be visualized as tree so that I can backtrack to any node and resume browsing on a new branch. The browser should also be doing memory management so that revisiting recent site is as fast as switching to another tab. And while we are at it, why not allow full text search across recently visited sites?
You're arguing in circles. I know it's compensation, and I'm not the one who proposed we make it need based. I'm pointing out why your solution wouldn't work.

>it should be taxed

We tax what we want to tax, and we offer deductions to encourage behavior that we think is beneficial. Scholarship income used for tuition isn't taxed. We tax capital gains differently from ordinary income. We offer mortgage interest deductions.

Should is subjective. There is no inherent reason to tax tuition waivers the same as employment income, apart from that's the way the IRS does it now (absent this specific deduction).
To be fair - most innovation boils down to this kind of incremental stuff. 99% of 'tech' is an amalgamation of more basic ideas, not 'magic leap' kind of innovation.

I mean, we all love the magic, but I think we're getting spoiled as of late with all the magic AI/Deep Learning stuff coming out.
That's pretty insightful, actually. I mean, outside of Kraken (terrible), who are Coinbase's (legal/compliant) competitors? Basically no one.

I wasn't calling you out. It was just a different perspective, mostly for readers' benefit. There are many people who feel that the poor are poor because they are incompetent or malicious, rather than because it's a self-sustaining cycle.

It's a good reminder to write less pointedly, though. If you have any tips on writing style or favorite authors, I'd love to hear them.

If you have a store that sells food without people making it for you on demand, I believe that's called a 7-Eleven. They have lots of vending machines and prepackaged food. To the extent that people are okay with eating that way, they'll stop going to McDonald's.

There was a great article about the sandwich industry in the UK that goes into this [1]. And yet, even for sandwiches, Subway does well making them on demand; selling prepackaged sandwiches is an enormous and growing market but it's not the entire market.

Wouldn’t you say there’s a difference between structured thinking (say, a kind of breadth-first search of ideas with pruning) and abstract thinking (which allows a programmer to, say, identify the need for a Form class on the backend to model and process POST data)? Bad programmers will just keep writing similar code to process the POST data with no abstraction about what is being done and why. Related, mathematicians use lemmas and theorems to reuse thought.
> collecting your parcel from a delivery office

That's not necessarily as easy as you seem to be making out, a lot of people don't have cars which rules out large or heavy packages and some delivery offices have inconvenient opening times (often business hours + Saturday but if you already have recurring commitments on Saturdays you might have to go through a lot of effort to make the time during the week).

Binding arbitration is probably the only thing making the legal risk of such a high-liability product/service manageable from Amazon's point of view. If it wasn't available, the product may not even exist.

Which is fine. Maybe something like this shouldn't exist until we have the technology to make it foolproof. At least to the extent where the expected lawsuit frequency is something Amazon is willing to take on.
The best way to ascertain this is to look at the skills being hired for by the companies.

Here is what IBM looks for in a block chain developer (whatever else you want to say about large companies, they put a lot of thought into the description):

3+ years of experience as a backend developer

Experience with Blockchain daemons such as Bitcoind and/or Stellar Core

Strong proficiency with Node.js, Java, and Golang ecosystems

Understanding the nature of asynchronous programming and its quirks

Understanding accessibility and security compliance

User authentication and authorization between multiple systems, servers, and environments

Integration of multiple data sources and databases into one system

Understanding fundamental design principles behind a scalable application

Understanding differences between multiple delivery platforms, such as mobile with API backends vs. desktop applications, and optimizing output to match the specific platform

Creating NoSQL database schemas that represent and support business processes

Implementing automated testing platforms and unit tests
Proficient understanding of code versioning tools, such as Git

Experience with other languages such as: C++, Kotlin, and/or python
While the official story is that it was a political issue (or "licensing hissy-fit" depending on your point of view), I often can't help but wonder if that was really somewhat of a cover for a bunch of stuck up C developers who simply hated C++.

Of course the one time I attempted to write something with Gtk+, it very much felt like a "We hate C++, so we're going to implement everything C++ does as conventions and macros on top of C" project.

In the early days, Linux/gcc also had some dynamic linking performance issues with complex C++ libraries. As a result, KDE apps actually did take a lot longer to start up than Gnome apps. However, once launched, the KDE stuff always felt like it actually ran faster. Thankfully those issues are long since fixed.
Solid point. I'm really surprised this doesn't already happen.

You could argue that this hasn't hurt on-demand services like iTunes and Amazon Video, where people could torrent the videos instead of buying/renting them. With piracy you're always going to lose some small number of customers, but if you make renting them legally easy, people will pay.

To some exuberant commenters in this thread: Young Americans are NOT accepting Communism. Most wish a slightly more socialist direction, not the full blown state ownership of the means of production. For example, many would like to see is single payer medicine; that's not the same thing as the government running the hospitals and employing the doctors. Many would like to see municipal broadband. They'd like to see a bit more consumer protection. Many would like to see more water systems remain under municipal control rather than being sold to a private, for-profit entity. In short, they'd like to see a bit more community works. I've yet seen anyone seriously advocate for government seizure of the means of production.

If you must think in terms of duality, state or privately controlled, there is perhaps a good rubric: If the industry is inherently monopolistic due to it controlling a singular resource (like a central park, or water), then the resource should be owned democratically by its community of users. In contrast, if the field can be competitive, then government should only be regulating the fair competition within that market. Note that even within a singular, monopolistic market there are always subordinate markets that are, in fact, competitive (e.g. parts & labour).

Democratic control need not imply centralized control. Even in the singular resource case, a democratically-controlled user or consumer cooperative specific to that resource is often a better organization structure than making it operated by an arm of a governmental entity. For example, rural electric companies are consumer cooperatives that serve their local area; often times they own & operate only the power lines and transmission (the monopoly part) and leave power generation (the competitive market part) to independent for-profit entities. Regional electric companies are not really part of a centralized government, yet they are democratically controlled by the subscribers who purchase electric service from them.

Sharealpha| on demande investments predictions
In 2014 the court struck down net neutrality rules that prevented blocking and discrimination, which the FCC had issued under Title I of the 1934 Communications Act. But in 2016 the court upheld net neutrality rules that prevented blocking and discrimination, which the FCC had issued under Title II.

Going back to the early 2000s, the FCC has espoused broadband neutrality principles that prevented discrimination against certain types of traffic. In 2005, the FCC articulated these principles in what became known as the “four freedoms” and used them to stop network providers from discriminating against traffic that competed with their own services, for example: in 2005 the FCC stopped phone company Madison River’s blocking of Vonage VoIP calls that competed with Madison’s call service; and in 2008 the FCC stopped Comcast’s blocking of online video services that competed with its on-demand cable offering.

Comcast sued, and in 2010 a federal appellate court ruled that Title I didn’t authorize the FCC to make Comcast comply with the FCC’s net neutrality policies. So the FCC then issued a new regulation in 2010 that, among other things, banned blocking and other “unreasonable discrimination.” Verizon then sued, and in 2014 the same court ruled that anti-blocking and anti-discrimination rules couldn’t be imposed under Title I. The court suggested, however, that the FCC could issue such rules if it reclassified broadband internet in a way that put them under Title II. In 2015, the FCC issued neutrality rules under Title II, and when ISPs again sued, the court this time upheld the rules and they are currently in effect.

Chairman Pai’s FCC wants to repeal those rules, even though the court held that they were valid in 2016, and even though the courts orders from 2010 and 2014 essentially preclude the FCC from issuing neutrality rules under Title I.

If you want to take a really deep dive into the history of neutrality, which goes back 50 years, I recommend reading this: https://www.wired.com/story/how-the-fccs-net-neutrality-plan...
Amazon Launches a New Message Broker Service in AWS
That's not why humans play games so why should it be for AI? We didn't consider running "solved" after the first Olympic games. AlphaZero is just better than any other algorithm at this time. A year ago that wasn't the case, in a year it may also not be the case. We learned something about developing AIs here which we can apply to the next. That doesn't mean Chess and Go are of no value to AI researchers, it shows that they are fertile ground for discovery.

These are terms used in a philosophical argument, so you have to be precise about definitions. In this case, non-existence is not possible once life begins. Non-existence is the alternative to creating new life. So , as far as we are concerned, in this context, non-existence is not considered to be what occurs after death.

I've been see more Elixir/Erlang stuff on HN recently. It makes me happy.

There's some useful stuff in here for sure. If this is your own blog post here is some feedback.

- It contains a lot of very Phoenix-specific tips, that could be useful to have in the title.

- I see you linked to the docs in a number of places. This is great. Blog posts can rot quickly into outdated documentation.

- You mention using Phoenix 1.3. It might be nice to have that right at the top, so someone who stumbles on this in 2 years can determine whether it's relevant for what they're using.

- You have all these examples of writing a blog application. Would be great to have this blog post hosted on that application itself, rather than Medium! ;)

Productive capacity is not so easy to migrate.
In most of Europe AFAIK deliveries are never left at the door, and the deliveryperson calls you shortly before stopping to check that you are at home. In this scenario if I owned a smartlock I could just open the door remotely for them, no need to buy their lock and app.
If I drove there twice a day I wouldn't need to go to work anymore, because it would (almost) cancel out my salary. Granted I don't work with an American salary, but they're not THAT much higher. I don't know if that's what you call cheap.
I wonder how exposure to Arthur Miller's The Crucible affects opinion on these types of accusations?
You’re right that it can be easy to spot comments that may be fake, but to have confidence that certain comments are fake requires further analysis. One reason is that the mere use of identical text in multiple comments (even large numbers of comments) isn’t necessarily evidence of misconduct – many public interest groups use web forms with pre-prepared comment text that people can fill out, or they circulate petitions for people to sign to provide consent to having the same “form letter” comment submitted on their behalf. So we look to other attributes that are shared across certain comments to help us determine if they’re likely fake. While we’ve already gathered enough evidence to conclude that a million comments are likely fake, we’re still analyzing others. And of course, it would be much easier and quicker to identify which comments are likely fake if we could analyze FCC records showing the source(s) of comments (which we would keep confidential given the possible identifying information), but the FCC refused to respond to our repeated requests over many months.
So take what I'm about to say with a grain of salt but I believe that current generation of quantum computers (quantum digital) is fundamentally flawed. Basically all architectures I've seen still use bits (qubits are still bits and use entanglement) as opposed to the superior signals. The class of computers I'm talking about is called continuous-variable quantum computers (https://en.wikipedia.org/wiki/Continuous-variable_quantum_in...). Unlike DQ, it doesn't use entanglement.

They are similar to the old school analog electric computers. They have some interesting properties and I can actually imagine programming one unlike DQ.

There's a fourth class, continuous analog with entanglement which are superior to both, DQ, and continuous-variable quantum computers but right now we should really be looking into the continous variable ones.
Congestion already has it's own price directly in increased travel time. Which pushes people to use optimal routes to a destination. However, routing around congestion increases pollution via trip length. So you want to increase peoples ability to go from A > B, not hinder peopling moving from A > B with increased cost.

PS: We want higher mileage people to get electric cars, so having no transit tax actually efficiently promotes higher mileage people from making the switch first. It's just one of many subsides associated with electric cars, but we will eventually just charge based on odometer readings.

I've noticed that the automated buys I have set up typically fail when the price is low and succeed when the price is high... according to Coinbase this is due to my bank.

But now when the price is high Coinbase can't manage to scale the website so that people can sell?

It would not be hard for coinbase to engineer a meta-strategy using targeted service failure to extract additional profits from the ecosystem's obvious trends. Not saying this is going on, but there are now to indications that this could be happening.

Someone is intending to buy at $12K so you fail the transaction for 3 hours if your simple model expects a higher price tomorrow (meanwhile buying some coin at market to use later when you succeed the transaction).
Great explanation, thanks.
