Are the whales actually the elites?

> "But Zynga’s big spenders really live up to their reputations. Customers in the top 20 percent spent an average of $571 in 2016, and customers in the top 1 percent spent more than $4,000 each! (This means, at Zynga, WI80=30x and WI99=49x.)"

I don't play Farmville and maybe I just don't get it, but I can't imagine normal people spending that kind of money on an online game (even if they are rich), unless there's some kind of addiction involved.

If someone told me that the top 1% of slot machine players (by amount spent) spent an average of $4,000 each per year, I wouldn't say "boy, they must be loaded to be able to afford that kind of cash", I would say "I think they have a gambling problem and many of them are probably spending money they can't afford."

Zynga isn't necessarily responsible for their users financial decisions, but it's kind of a different situation if they're catering to the elite vs exploiting psychology to extract money from people who make make poor financial decisions. I don't know anything about Zynga's practices and don't have an opinion one way or another, but I found the dollar amounts kind of surprising and potentially alarming.

maybe someone can help me understand. I now get homoiconisity but the example he uses doesn't seem to explain why the macro is needed. He explains a problem that can be solved by writing a function. Instead he presents what seems to be in effect an unevaluated function... so what's the point?
Yes absolutely. Prolog would kinda sorta do the same thing. It would be much faster though. You can build a mechanical computer with gears and cams, but it’s big and slow.

This style is much quicker than a deterministic computer with an rng. It wobbles between all the valid states at the ghz range, rather than the thousands of cycles prolog would need.
Kind of like LISP. When I read McCarthy's original papers, it had that same feeling of simplicity, and you could easily see how it mapped directly to the hardware. Original papers are often the best. Chuck Moores book on FORTH was finally released as a PDF, but he wrote it in the early 1970's. Amazing. I knew FORTH was linked to LISP, and the link is explained in there.
I'm referring to how the network is actually implemented. The paper is simply vague on the point.
I feel like machine learning is one of those terms that has lost all defined meaning, under a bombardment of hype, corporate buzzwordism, and other horseshit.

Of course, you'd have to trust Shazam to provide accurate data.
There’s a point where this trade off (let the market decide, effectively) starts to fall over. Discoverability on Google Play has long been an issue for many people I know (sadly I have no formal data on this). Like many things I’m not sure either option is a clear winner.
To a point... but it's so prolific that you should be testing to falsify it most of the time.
Run a custom ROM and monitor network connections. Don't trust, verify.

The article says

"Most functional programming languages with automatic currying have syntax where there is no difference between add(1, 2) and add(1)(2)"

and goes on to talk about unidiomatic syntax.

In Haskell, the two options are "add (1,2)" and "add 1 2"
The latter, curried form, involving whitespace, works because Haskell parses it as an application of a to 1, followed by an application of the resulting value to 2. This syntax is inspired by the lambda calculus, so it's not really whitespace that's the concept, just "juxtaposition of terms" implies application.
How can you be sure? Maybe you have the source code?
I was recently out and heard a country song I’m sure is one of the most inane songs I’ve ever heard in my life. I Shazam’d this atrocity to discover it was a two year old song by American Idol contestant, Kellie Pickler. How do I feel now, better or worse?
Because this matches their usefulness - in services that scale to a huge audience, the less-than-the-best aren't useful much.

Assuming that I'm going to read 50 books of a certain niche genre that has 5000 writers worldwide, the best 50 writers in that niche have a significant economic value (and thus deserve huge rewards, because we want them to continue writing) the next 50 have some value, and the remaining 4900 writers in that niche are useless, they can do it as a hobby if they want but we're not going to support them much - we don't need their writing, because someone else can do it better. Why would I ever want to read the 101st (according to my preferences) best book if I'll never get the time to read the 100 books that I'd like more than that? It might as well have never been written as far as I care.

This is the inevitable result of abundance, of having more choices than you'd possibly need. Think about this from the perspective of food - if you want an apple, and are walking by a tree that has a hundred apples of various ripeness. The few most ripe apples are useful - you pick one of them; if you want a second one or have a friend with you, then you might want a few more... but the 90% that aren't as attractive have zero value if the tree has more apples than anyone could ever want to consume. And this is the case for writing; there's more fiction writing than anyone might ever be able to read, thus you're inevitably reading just a small fraction of it, and if something's good but worse than the many alternatives, then it's worthless.

The same applies in any industry that scales. I want to watch a top-10 footballer, but the top 10000th is useless to watch (although they're really good, they're among the best 0.1% of the millions of soccer players worldwide); the same goes for music, software, all kinds of creative works.

It's very possible he never imagined* a non-mining full-node(as opposed to an spv node). Regardless full-nodes do enforce the consensus rules and reject invalid blocks.

* Another phenomenon he didn't imagine was mining pools, which drastically changed the dynamics of mining.
>If an app lacks value, it will get a poor rating.

Ideally, yeah. The ongoing arms race between apple and review farmers makes that signal less likely to work.
> “Responsible disclosure” is great stuff for creating a culture of free outsourcing of tech companies’ most imporant feature (security) to the same people that paid those companies thousands of dollars for that privilege.

Also "Responsible disclosure" means absolute nothing to most people who are not security researchers. They don't know about it, even if there is a bounty and they could make a decent profit, they have no idea what those things are. They notice they can get root access or the focus sends their password to Slack and they'll tweet about it.
I guess I just have never found support for that in the nakamoto paper. You obviously have strong feelings about it, and I'm not trying to provoke an argument. I just still don't understand where in the paper there is any discussion of non-mining nodes. The only place I can find mention of nodes that are not working on constructing new blocks on the network is in Section 8 re: the simplified verification protocol.
So it just splits the code up into setImmediate/setTimeout calls?
In order to understand, try replacing "privacy" in your blog response with some other thing that you care deeply about.

I believe the most straightforward way to normalize something you believe is wrong is to simply give up and stop calling it out as wrong.

That said, if people think my viewpoint does not add to the conversation, I accept downvotes with grace.
Curating an app store is not antitrust.
"That is the beauty of it. It is only eight pages long, but fundamentally changes the concept of money."

Not really; it only serves to validate the beliefs of people who already agreed with the basic premise that money is something that can exist without central authority. That view was already common long before the Bitcoin paper. Plenty of libertarians believe that money is an emergent phenomenon of free markets, something which arises on its own as the market converges on a common currency as its medium of exchange.

On the other hand, if you are aligned with the mainstream of economics, the entire premise of the paper is easily dismissed. In that view, money can never be separated from banks, the paper is basically nonsense.

The great extent of their database can be annoying at times. I turned on the TV during the Winter Olympics once, and saw that one of the ice skating events where the competitors skate to music was on--probably Ice Dancing.

The performance being shown was using some fairly well known piece of classical music that I did recognize, so I tried Shazam [1] and it identified it, but not in the way I wanted. Instead of telling me the name of the piece and the composer, it told me who the skaters were, that it was from their Winter Olympics routine, and what round of the competition it was from.

[1] ...I'm not actually sure if it was Shazam. Might have been SoundHound.
Well, capitalism doesn’t quite work either. But people seem to prefer it for some reason....
Probably the opposite would occur. It likely would have a "decapitation" effect on the economy and everyone would become poor --kind of like what we see in VZ, where industries were nationalized, owners skipped town, state didn't have the expertise and state exacerbated issue by not doing basic maintenance and upgrades. End result is more poverty and more murder, etc.
Or you install a DAS in the store and monitor the traffic of phones connected to that.
What it did, was it made it possible to create a decentralized store of value without the need of a central authority. And that has definitely made people question their understanding of what money even is.
Good luck verifying that radio chip.
It doesn't prevent lying (or "exaggerating"), but it takes more work to fill in details for a long resume, that's all.

I just published my second book through CreateSpace, any phasing-out would be news to me, but I'm very curious what you mean. My experience the second time around seemed basically identical to the first—what's getting phased out?
The usage-related data sets that Shazam has collected over its operational history are likely the biggest driver of value for this deal. Think about the insight you could gain by cross-referencing Shazam lookups with iTunes downloads. Probably lots of insight in how certain genre fan bases intersect, good predictive analytics on time-to-monetization of hot underground bands, etc
Equally elucidating are the responses on the Cryptography List from other cryptographers[1], plus the responses a few months later when Bitcoin 0.1 was released[2].

You can pretty easily tell which cryptographers read the whitepaper and which ones did not. :)

The thing about rich people is that they don't spend most of their money. Instead, they keep it locked up in relatively illiquid investments that yield big returns over long terms. The poor are stuck with riskier short term investments, if they can afford to invest at all.
Insurers are rewarding Tesla owners for using Autopilot
But these bugs the kind that anyone could stumble upon, and if they are not security researches their first instinct is to let everyone know about a crazy thing they found. I can't really blame them.

If companies want more responsible disclosure they should introduce harder to find bugs - sneaky edge cases in memory allocation sequences, stuff you'd have to pore over a disassembler for weeks, or slightly weakened PRNGs that would take some serious knowledge of finite fields to discover :-)

Bitcoin is trying to move transactions off the blockchain to fix this issue... bitcoin cash is what bitcoin was supposed to be (increased block size)...
No good reason, really. It could have been any of them —they’re all pretty much upside down and backward, to be honest. I guess it’s a way to enforce stability.
Perhaps it should give you pause with that belief structure when you realize the word 'mining' doesn't even exist in the bitcoin whitepaper. It is only the nodes that exist, because it is only the nodes that validate, and everything that didn't have anything to do with validation is rightly considered a secondary concern of the protocol.

So there are nodes, which are peers. And there are people who need nodes for performing bitcoin transactions, and some of those people are miners, and some of them are just making good-ol-fashioned transactions. The correct term is "I am a peer, and I use this node for my transactions, which create blocks". Or "I am a peer, and I use this node for my transactions, which are payments."

As a TreeyStyleTabs fan, I am 100% happy with Firefox 57.

As you probably know, no other browser (other than ones based on older Firefox versions) supports anything like Tab Mix Plus. And there's a reason for that.
And don't forget, the battery tech keeps getting better. How long til the Model 3 hits 400 miles, or 500?
I believe the original intention was that all nodes would be mining nodes, and that there would be tens of thousands, or even hundreds of thousands.

I believe in 2008 Satoshi did not understand the full implications of ASICs or economies of scale. (S)he probably didn't even realize that ASICs existed.

Regardless of the whitepaper, in our modern cyberscape the only way to be certain that the original rules (21m coins, can only spend your own money, etc.) are followed is to be confident that a wide and deep pool of users are verifying them. That is strictly at odds with heavy on-chain scaling.
They do better than just pay protection money.

Ask HN: Will self-driving cars lower the price in core Bay area cities?
Housing price is crazy in the core Bay area now.

After 5-10 years, will housing prices lower in prime areas such as Mountain View or Sunnyvale and rise in "bad" and distant areas because people can sleep or work in their cars, thus be tolerant to longer commute?

Heard someone currently just uses Tesla autopilot in highway commute and plays his cellphone. Will this be adopted by more people soon?

That's a very nice statement of the innovator's dilemma.
There are two sides to that issue. On the one hand, the point of publishing research is to make knowledge available to humanity, so if you are having trouble understanding even the basic premise of a research paper (what problem it is addressing, etc.) then the authors are failing to achieve that goal. On the other hand, if every published paper was written to be accessible for non-experts in the field, papers would become longer and longer over time as lines of research progressed.

Unfortunately there is no reward for researchers taking the time to write tutorial and survey papers that give more readable explanations of particular lines of work.

The issue here is Apple doesn't want users to have to avoid low-rated apps–it defeats the whole point of having a walled garden and the app review process if bad apps are allowed through.
If you are interested in getting into lisp, I would recommend you start with Racket.

Racket has several different languages (the main one called racket) that are all trivially interoperable.

Maybe actually take a look at the paper.

SHA-256 could be more broken than SHA-1 and it would still serve perfectly well for mining.

If you don't reuse addresses then even if ECDSA is broken then your coins are still safe. And ECDSA being broken is pretty much the darkest scenario. In which case it can simply be replaced with something else starting at specific block.

RIPEMD-160 just hides your public key.
And I bet talking to yourself helps think through solutions to problems. At least that's what I choose to believe when I find I am talking to myself.
Wow I forgot about those. Templating in general sucks, it’s just so hard to create something that makes a program accessible and has safety for user generated content.
If I submit ten copies of the same game with different background colors, then all of them would get the same rating, because all of them provide the same value/quality. If the game's not poor, it will not get a poor rating.

Nonetheless, Apple would (rightly) want to ensure that this doesn't happen, since all the duplicates provide negative value, crowding out the competition, harming discoverability. On their own each of them would provide value, the problem is in duplication.
This is incorrect. The 'peer' in 'peer-to-peer electronic cash' is a reference to a counterparty to a transaction. It's "peer-to-peer" because there is no "trusted third party" (a term used in the white paper) acting as an intermediary.

Satoshi extensively detailed the ability of participants in the Bitcoin network to use light clients, that don't fully validate the blockchain, and predicted that the vast majority of people would use such clients in the future.

The vision of Bitcoin Core that you're promoting totally contradicts the one promulgated in the Bitcoin white paper and further descriptions provided by Satoshi.

The idea of the vast majority of people not being able to hold their own private keys, because transaction fees are so high, contradicts several core features of Bitcoin that are described in the white paper.

The new podcasts app is absolutely terrible. My girlfriend is a heavy listener and the list of podcasts she has available takes between 30-45 seconds if it loads at all. Releasing the new version of this app was absolutely a regression, and I'm shocked that it actually got past any form of QA at all.

My only guess here is that a team felt the need to ship a new shiny product, even if it wasn't close to feature parity with the old one and is pretty unusable for a normal workflow without becoming quickly frustrated.

I assume business metrics, promotions, and appeal to novelty got in the way of functionality and user experience. My girlfriend mentioned that she wanted to turn off automatic updates because she would have never updated this app to the new version, which is quite frustrating as somebody with some basic netsec knowledge.

Apple, what happened?
