That is exactly how a lot of automobile businesses work.

Especially budget markets like India and the 2 wheeler industry.
Yes, that is what I mean. It can be measured in that way if the product being advertised is something that's meant to be bought right now, online. But many products don't really work like that.

For example, we did multiple campaigns for major sports teams. How are they supposed to measure the impact on sales of tickets and memorabilia? The idea isn't to generate sales of product X right now, it's to energize and grow your team's fan base, which will hopefully lead to more people buying more things over time.

Another example: we did many campaigns for food and beverage brands. People don't tend to order those things right now, online. You're just trying to grow your brand in hopes that more people will buy that snack or drink the next time they're at the store.

So I amend my previous statement to agree with you that semi-precise metrics are possible if you're trying to get someone to buy a specific product online right now. That description covers a lot of companies, and they probably have good metrics.

But a big consumer-goods company like P&G probably isn't doing that kind of marketing. They're trying to get you to think of brand X the next time you're getting groceries. That makes impact of ads devilishly hard to measure, regardless of whether the ads are online or on TV.
We had a few places where we had some headscratchers.

First, it took a little time to get the hang of json manipulation. We got to a solution we liked, but a dynamically typed language like groovy has some advantages there.

Closed classes by default can make some testing a little more difficult. We have continued using Spock rather than moving our tests to Kotlin, and there are a few places where we compromise our design until we can figure out a better way. (Yes. Dependency Injection and less coupling is the answer, alongside adding a level of abstraction in between third parties. The devil is in the details.)

In general, we like it and are planning on expanding our use, but conversion has had its challenges.
Yes, a curated app store is a great option to have.

It's been said that the app-store-only model is not basically different because you can still buy an unrestricted competing device. I kind of agree, but that's sort of like saying people in China can still decide to move to another country. The cheaper such options are, the more weight to give such an argument. Most people aren't going to carry two phones around.
I don't see anything wrong with the first picture. It's gruff, but it's not repulsive.
How do they become invalid?

Suppose a station uses a mercury thermometer for the first 80 years then switches to a thermocouple, with an overlap of 10 years were both thermometers are run side-by-side. Suppose also that it shows that the old thermometer consistently reads 0.25° warmer than the digital one, and that calibration tests show that the new thermometer is accurate.

Do all of the old data points get thrown out of the window? What's wrong with adjusting the old temperatures by 0.25°?
This is exactly how it's done - the amount you get paid is relative to your engagement. How this correlates with sales is speculative at best.
Parallelization automatically, special constructs for sparse matrixes, complex manipulation of multidimensional arrays without need for making sure they are constructed correctly. Not to mention never having to worry about an indexing error, unless you are specifically asking for an index, in which case the bug is in your design, not the program. Built in methods for sorting and searching that are very efficient, as well as filtering. Also, J is faster when you give it all the data you can at once, rather than moving through index by index. A lot of these advantages take time to really be aware of, much like Erlang's bread and butter often hiding behind much more than one article.
Just so there's no misunderstanding: I've used CL and I know it's interactive features are better than python. I wasn't saying python is comparable here.

I just want to clarify that the method I mentioned doesn't require finding all references to the original function. It's mutating the function object, so all references will see the updated version.
Cryptocurrencies are best described as being like penny stocks - they don't represent any underlying value or investment, meaning that prices are low and large gains can be realised through a small change in price - making them vulnerable to people manipulating investors as part of a pump and dump scheme.

From the Willy bot through to the latest ICO craze, the whole cryptocurrency scene is riddled with people engaging in pumping prices - which means that any reverses in price hit sentiment hard and cause price shocks, something I think we're going to be seeing a lot more of over the next year or so...
Even if we ignore appearances, at some point there is just a max size convenience limit to house pets.
> What is your proposed solution? How does one limit a free, public resource to only people with homes?

We already limit library use to those who live within the library's community. Just require a library card to get in, too. Morals aside, the logistics would be simple.

> How do people without homes "completely destroy the purpose"? Are they stealing books? Breaking computers? Barricading the doors?

Shooting up heroin in the bathroom? Using the water fountains to wash up. Talking angrily to their schizophrenic delusions? Stinking to high heaven? Saying "completely destroy the purpose" is a bit of an exaggeration - but the mission of the library is hampered a bit if you make them defacto daytime homeless shelters.

> Do you really believe that all people without homes have "given up on life"?

He was exaggerating, but yes - many homeless have no reasonable expectation of improving their circumstances.

> Do you think education could be a productive method for reducing the number of people without homes?

Those who aren't mentally ill or completely socially maladjusted, sure. Of course, there's a difference between "education" and "just putting them in a building full of information and crossing your fingers".

I don't say that all of your criticisms were wrong - but you went off the rails in the opposite extreme of the person you replied to. Any solution we come up with should acknowledge that libraries are vulnerable to the tragedy of the commons, and a great percentage of the homeless are not going to improve themselves without the aid of services that the library has no business providing.
Useful context, thanks!
Any ideas for a marketplace?
just blast me with ideas.

service, rental or product is fine.
I actually started cutting pork out of my diet after a comment on HN about vegetarianism and meat choices pointed out the same thing. I still eat it -- because it's so ubiquitous -- but am trying to shift to chicken whenever I have the choice.

Eating something that's smart and social just seems wrong to me, when there are plenty of stupider animals as alternatives.

Also... watch Okja on Netflix ( https://www.netflix.com/title/80091936 ), especially the ending.
What happens when someone builds an autonomous Bitcoin exchange on Ethereum?
Anyone that's ever taken a serious look at online advertising knows that the elephant in the room is that most of it doesn't work. P&G is just the latest large firm to call that out.
Personal attacks are not helpful.
Decentralized exchanges are already in the works.
And yet the wild population still needs to be controlled.

That's a very naive point of view.

Apple has shown the willingness to compromise to access the Chinese market, so there's absolutely no reason to believe that they wouldn't or haven't bow to their other demands, including the weakening of their device security.
a marketplace for code, all kinds of code would be nice. There is themeforest but it's only accepting PHP/Javascript stuff.
> That sounds more like a mental health issue though

Yes, absolutely, the primary causes of homelessness are drug addiction and mental health issues. There are other causes, and I'd never advocate being callous or dismissive toward the homeless- but this is the reason people find large concentrations of them off-putting.
There are plenty of already working one
You may get extreme edge cases, but you're going to pay more to get them because the conversion rate will be low. You'd get more out of targeting placements directly because you would hit all people looking for a new mattress there, not just people that have already purchased one.
As a counterpoint I recently saw an astonishing-if-true stat of the number of animals killed per million calories by food [1]. About 14x as many chickens die vs pigs. Even if pigs are smarter, that may change the way you weight the ethics a bit.

We should all be eating brainless bivalves perhaps? [2]

>I've seen many campaigns where we were getting huge ROI in terms of actual dollars. So there are clearly lots of people out there who do click on ads and take action.

That's the problem, though. You can tell me that the user clicked on the ad and then bought my product; but was the user going to scroll down to my organic search result, click on that and buy anyhow? The advertising sellers claim that they should be credited with the sale, when all they are providing is moving the last link up; at least in the industry I was in, a user, generally speaking, isn't going to sign up with a VPS provider they haven't heard of. Sure, sure, putting a special in front of them can move you from second or third place to first place, and there's value in that, but really some brand advertising needs to be done before you can sell at all, and as you pointed out, measuring the effectiveness of brand advertising is super hard.

I suppose there are some products where the user really is going to buy the product first linked; but I think there are a lot of products where the user doesn't make a buying decision for some time, and the last click... may not have a lot to do with what order the links are in.

I think this is the real problem with online advertising; tracking that last click into a purchase is fairly easy (though, as you point out, some people don't even do that) but figuring out how much of that purchase was because the link was first, and how much of that purchase was because the user had previous knowledge of you? that's hard - I understand that a lot of research is being expended in this direction, and that this is the value proposition that Facebook claims, but... it's a hard problem, and depending on the product, you could reasonably argue that the state of the art isn't as good as the people selling advertising say it is.
Many people making "REST" APIs don't even know what media types are which means many REST APIs are impure. That doesn't mean that the author won't add these based on feedback, or that they they have something in particular against describing it as an HTTP API. In many cases people searching for a REST API to access AD probably won't care about this particular nuance.
About 10 years ago the CP block list used by multiple nordic ISPs were leaked and people jumped on the opportunity to test the quality of those listed. The result they got where that a couple percent was CP and the remaining was either dead or non-CP.

The problem (as was discussed in Sweden during that time), is that the list can't be made transparent since according to the police that would "guide" people to location of CP, and the owners of website is not contacted since thats not the job of those operating the lists. There is also no one willing to employ and pay people to clean the list of domains once the content is gone.

In one particular case there was a Bonsai website that got listed. Those studying the leaked list called the owners of it and the owners were completely unaware that most people in the nordic countries could not access their website since it was blocked. The Swedish police speculated in a interview that the site had been hacked and that the operators (web host/designers) cleaned it without notifying the site owners.

As a administrator for web hosting, I would be amiss if I didn't add to this that hacked websites have generally a multiple of payloads at the time anyone will start notice that something is amiss. A site could be sending spam, selling fake shoes, and running a CP site all at the same time, and the operators could have notices one of the payloads then decided to reinstall (and update).
The percentage of iPhone/Mac users that care enough about VPN in China to switch to Android/Windows wouldn't even be a rounding error.
"Fundamental mode" handles all those things great, and anything you can think of. Escape the shackles of syntax highlighting and special modes and you'll be free, hackers, you'll be free...
what are you, racist pig ?!
too bad they're more decentralized marketplaces than decentralized exchanges.
I had a similar experience when I first started learning machine learning; thinking in terms of, and manipulating data as, matrices and vectors was not easy at the beginning -- even if the rest of language (Python) was 'classic'.

I guess pushing the envelop with a language like J, where everything is an array, plus the unusual function manipulation, would make it even more alien; it's like touring another planet. At least that's what I felt while reading this.

---

That said, it's really boggles me that every time someone tries to explain a new paradigm or idiom, they feel obliged to make it look as superior way of doing things. (Such as in : "J helps us get better at expressing that universal pattern.").

Can't we just express difference just like that; a different new thing. It doesn't have to be better, or worse.

Otherwise, I really enjoyed the article.
The alternative is to stop doing business in China, is that what you want Apple to do?
This is what I never understood about bitcoins's reputation, especially earlier on, about its supposed anonymity. I suppose that's much less the case now. But it always seemed odd that people considered it at all anonymous when the blockchain kept a record of everything. Sure it might not be immediately identifiable with a specific individual, but unless it was a wholly closed system, entry & exit points would always be clear, along with all the hops from wallet to wallet along the way.

And the longer the system exists, the more information will accumulate that would allow anyone with an interest in doing so to correlate blockchain transactions to "real-world" people & systems.

I'm sure I'm missing something though, since I'm by no means a cryptologist, or more than an interested spectator on crypto-coins. (I mined about 0.1 bc back when it was still possible to do that in a week or so on a mid-range AMD GPU. and, shocked at the rise in value, cashed it in for about $200 a few years ago.)
While the author "looked at anthologies that collected international, American, and English-language poems", there is a leaning towards American poetry as 11 of the 20 anthologies surveyed were anthologies of American poetry (based on their titles, bottom of the page).

I'm curious what you mean here with the implication that you couldn't simply add Groovy code to your existing apps built with Maven. Have you tried it?

It has been probably over 5 years but when I was writing a lot of Java and Groovy, we were standardized on using Maven at that company. The Groovy Maven plugins worked and I had several projects with various mixtures of Groovy, all built with Maven: from Java with Groovy tests, to Groovy and Java throughout, to pure Groovy web services. It was a bit of a pain getting the configuration set up initially but it worked well.

That's the majority of bookstores in Austin.
Quite possible that that's the joke here, but people have been saying this since the Wild West was actually ending.
Exactly. Coordinate with police and enforce the rules. Public spaces are created and maintained by enforcing liberal rules of access, not no rules of access.
and so Bezos buys the post while the control FB and Google have on advertising (and increasingly the internet in general) just makes Journalism ever more reliant on them.
Not only smart and sensitive, they are very very clean. We have a minipig and it won't do any of its stuff on its house or surroundings. I'm sure the big ones, if weren't forced because of us humans to live enclosed, would behave the same way.
Well, we /did/ turn wolves into Pomeranians.
You could say the same about dogs and cats. Wouldn't everyone love it if their puppy or kitten would stay cute forever.

But then again, if you've somehow invented a way for animals to stay looking young forever, 7 billion humans might want a word with you...
> ChainCoin has no value proposition, nothing to differentiate it, and the dev team abandoned it a long time ago, so why would anyone purchase this crypto? It's the same with stocks; you have to be able to understand the financials, product, roadmap, etc. of the company you're investing in.

Same reason people buy deep out of the money call options or do leveraged FX trading - they just like to gamble. The whole FX brokerage business (and that includes crypto) is basically run like a casino.
I would imagine Google thought the same. If this was five or more years ago and Xiaomi did not exist, there may be more pressure from the people. However there is a good alternative to the iPhone and the government would probably just say take it or leave it. It would give the government the perfect excuse to ban iPhone and have their citizens use a home grown phone that would be more compliant to the government's wishes.
I've considered that but was concerned about accidental calls to emergency services (young child here). Maybe android can be locked down to have the cellular radio always off, I should look into it.
https://bisq.io/ is a decentralised exchange.
A way to sell produce from small farms (very small like a few dozen square feet). Like a farmers market but not having to sit in a stall all day.

Some way to sell small amounts of scrap metal.

A place to sell all the consumer stuff that usually gets thrown in the trash (or sometimes taken to good will). Ikea tables, pots and pans, and the like.
This is an American canard, but it's not really true. Usually, public broadcasting reflects the consensus of where the middle is, with a slant towards social justice, almost unavoidable when criticizing public policy - usually stories are about something the government isn't doing, or is doing wrong, rather than shouldn't be doing.

If a public broadcaster publishes plainly biased stories, independent media can lambast them. But the shaming only has effect if the independent media is itself taken seriously; so the critique has to come from the middle ground.

What you won't get from publicly funded news is a rounded perspective on what opposing camps think. The extremes are lopped off; you won't get small government conservative ideology, and you won't get communist ideology. Being anodyne and factual is the best defense against criticism from both independent media and political sources.

If one's own position is significantly to one side of the political spectrum, naturally the middle looks like it's on the other side.
I look forward to your diversified collection of anthologized poetry
The charges seem exaggerated. If he's responsible or directly involved in the Mt. Gox theft, then they should prosecute him for that. The referencing of Internet usernames as evidence of crimes indicates they have a weak case or they're using it as public relations campaign against bitcoin.

The price of Litecoin was usually higher on btc-e I think solely because people would deposit btc and buy ltc as a way to hide the source of their coins. It was widely considered shady but trustworthy by its longevity.

If a rational actor sees no way out but to use a nuke, then there is a much larger irrational actor that is tyrannizing the world and needs to be destroyed. And since the actor is rational, it will have carefully considered the choice and have come to the conclusion that the loss of life was worth it, for an end of tyranny.
Note that ecto now has a :source option on schema fields which allows you to map a third party db into your own field naming scheme. Very useful.
If you want this behavior, you can just panic if an error is returned. Or you can divide the set of errors into expected and unexpected kinds, and panic only on the unexpected ones.

But the main reason this is the case is because in Go, errors are things that can arise from correctly behaving functions. If someone passes you invalid input, it's correct to return an error. You wouldn't want this to show up in as bad input in a fuzzer. Most fuzz test cases after all will not be correct input.

You can "expect" but if you only have one lock to unlock, it can be anything from 1 to 1000 attempts.

If you had 1000 locks, you can expect that the average would be 500 (if the numbers were truly random), but it still means that you might need one try for some locks, and 999 tries for some other lock.
