The confusion results from the conception that the market (any market) has a single price. It doesn't. When exchanges (stock exchanges, currency exchanges, commodity exchanges) execute trades, they do so with something called an "order book". You can think of it more like an available histogram of potential trade prices. The transactions tend to settle at the nexus of where buyers meet sellers, but if there's only $1 worth of BTC available at the "1 BTC=$10000" rate, then if you want all of your $10 transaction to execute now you will have to pay more. Alternatively you can leave your order at the "1:10000" rate and hope that someone comes and picks it up.

"the best" is an exageration. The web is named so for a reason: it's a graph, not strictly hierarchical. Which is rather difficult to represent in a list format.

For wikipedia e.g. I really want to have a graph instead of a linear history view, in at least 2 dimensions: ordered by time of visit and connection to related articles. I'm kinda ashamed I never got around to make this in 10 years.

In the short term it would still probably take a lot of computing power. If you can figure out the goal alignment problem (or even simpler parts like just how to get the AI to let you turn it off) then maybe the first version can help us prevent rogue general intelligences that do things we don't want.

It is a hard problem though which is why there's all the talk of existential risk. It's also a little nuanced to explain why there's concern or why people should work on the problem.

I thought this post from yesterday was a good response to someone stating that an intelligence explosion was impossible (the original article it's responding to is linked within it): https://intelligence.org/2017/12/06/chollet/

The pledge is $1.

The pledgee receives 95% of the pledge, $0.95.

The pledger is charged $1 PLUS the "processing fees", which are an ADDITIONAL 2.9% of the pledge (2.9 cents) and 35 cents fixed.

> Also in this case it would mean that in that case Patreon ends up taking 31% of the actual money spent by the pledger.

Yep, and batching charges means much of that 31% isn't actually going to real processing fees, but into Patreon's pocket.

Their recent (September) taking of $60M in VC money may provide a motive for this approach.

With a startup I was working on, we managed to get meetings with the CEO of the world's largest fashion company and several others with $10b+ revenue.

This is pretty fascinating! Though the concept seems to work only for convex problems (in particular, problems which have strong duality; this excludes NNs in almost their entirety, except 1 layer nets), but the application is nice and straightforward.

I wonder if there is a similar lower-bound which can be constructed for non convex problems which retain enough properties for this method to be useful?
Thanks, this is a really interesting way of looking at it. The change from $0-1000 is still not comparable to the other 2x gains. I looked up $500-$1000 and it looks like it took about 1000 days.

Yep. They pay 1.9% (source: https://patreon.zendesk.com/hc/en-us/articles/204606125-How-...)

Also, Paypal offers a 5 cents + 5% micropayments rate that they take advantage of.

The 35 cents plus 2.9% is clearly designed to make you think that they are processing fees and I'd be very surprised if Patreon wasn't putting at least half of that into their pocket.

How AI Is Redefining the HR Function
Hey, I hope you saw my above price about how the market works.

So to give you a little more info:
1) Yes, there are big players (aka "whales"), and the rest of the "small fish", all playing in the same pond. The interesting thing about cryptos is that the are more "money-like" than "stock-like" when it comes to trading. Meaning just like money, where I can buy a fraction of a $, I can also buy a fraction of a bitcoin. So there are a lot of smaller players who will buy, say .01 BTC for $150 right now.

But while there is a general consensus that bitcoin is $15k by virtue of people paying that much for it, the "whales" (people with a lot of money or coins), can cause issues because they can put a lot of volume on or take a lot of volume off the order book at once. This happened to Ether this year, dumping the price for a few minutes from >$300 down to about 10 cents for a few minutes! https://blog.gdax.com/eth-usd-trading-update-5d8142b5bdc1

In fact, there is some speculation that a lot of the rise right now is from Wall St. / big firms buying up a lot of coin, as futures trading on Bitcoin is coming in the coming weeks! (But I don't know enough to comment on that theory)

As far as preventing exchanges themselves from colluding... it would be difficult but not impossible, because again the price on the exchanges comes from the traders, not the exchanges themselves. (Theoretically it is possible that an exchange could do a bunch of "wash trading" / make up a bunch of fake trade volume to make demand look higher than it was, but given that there are a number of exchanges in a number of different countries, coordination there might be difficult)
Have to be careful with magnesium, too much and you'll spend the entire day on the toilet been reminded that topologically humans are a tube.
Coinbase being unavailable during times of extreme volatility is not a new thing. Today's swing was 14k up to 19k then down to 15k or so over a period of an hour of severely degraded access.

I'll go out on a limb and say that much of the recent spike can probably be attributed to the 100k++ accounts open on Thanksgiving weekend getting funded today and everyone losing their shit mashing the Market Buy button which get instantly executed. The mechanics of vast market buy orders with no liquidity is well known.
Where does this estimate come from? You’re talking about an event with no precedence, nothing even close.

What are you modeling that suggests something like that in 10 years?
You're going to be pedaling that idea for a long time before you convince lawyers that it's in their interest to generalize on expected outcomes.
>Is there a small amount of big players that are playing with the price?

We don't really know.

>Or is there a general consensus that the price is $15K. And wouldn't there have to be people that we willing to pay this price? What prevents the exchanges from colluding and raising the price artificially?

Well the exchanges could be running buy-bots but I think the more likely collusion is going to be big-players selling to themselves, if a big player is filling up both sides of the order book they can make it look like there is a lot of activity and drive the price up that way. Now is this that or is it organic? I'm not sure we have a good way to tell.
The discrepancy in quality probably indicates a deeper deficit of maturity across the software engineering discipline in general.
There's a rumor floating around that Stripe has taken issue with their batching model and that they're being forced to stop batching, which would absolutely justify this change since then Y=X, but I've not been able to find any solid evidence one way or the other about that.

The FCC is willfully ignorant - and that is 100% wrong. How many people on the street, who innocently don't know how the Internet works, might agree with this FCC statement though?

1 - Theoretically yes, but this is highly error prone and needs to be repeated on every update. Taking human factors into account, it's not a reliable strategy imho.

2 - My point isn't that a strict CSP makes the app magically secure, just that without it there's realistically no hope, and there's no point in wasting energy on trying to run a nontrivial app that doesn't have a strict CSP locally with the hope of getting around the security concerns of remotely hosted html/js.

If you load a local html file with a strict CSP into Chrome with no extensions installed, that's actually a pretty darn secure execution environment. It's much easier to verify than a native app, for example, and it can do a lot less damage. Based on a single line at the top of the file, you can be certain that the app doesn't load remote js or css, doesn't use eval, only communicates with specific domains, etc. It isn't magic, but it can get you a long way and it does offer numerous clear, concrete benefits vs. a remotely hosted app.
My informed opinion is that Toyota's software is robust but crappy.

The software you would use to configure the parameters in the car (e.g sensitivity of headlights turning on, whether or not it'll chime when you're not wearing your seatbelt) hasn't even been ported to 64 bits yet. It seems to have been written by one of their O.E.Ms (Denso) and it seems like the cars have used many of the same design patterns since the 90s.

Look no further than the infotainment system, it's always a generation behind other automakers and we all know that most automakers don't set the high bar of consumer technology.

That could work in the case where the parameter is a class which is movable but not copyable, but I'd still prefer an rvalue reference in that case because it makes your meaning obvious without having to refer to the class definition or documentation.
I fail to see how UBI isn't a service. It's using a made-up system (money), to make sure that people have viable options in life.

Our company is focused on development and auditing services in the field since 2014 (as an spin-off of a security company founded in 2003). I can speak from our experience:

- We hire a lot of people without specific blockchain experience since there are not so many people experienced in the field. This means, in average, people learn fast except if the development work requires modifying or inventing new stuff at the core level (e.g. Bitcoin Core, mining pool software, protocols, security, reverse engineering, ICO and general source code auditing).

- If you want to develop Solidity smart contracts you can learn fast but need to take into account the security aspect which has many ambiguities.

- If you want to learn about wallets and back-end services you need to have some knowledge about how the specific cryptocurrency works and the common (easy) pitfalls a newbie can have.

- JavaScript/NodeJS, like it or not, is the language where the latest high level libs are available.

- Now, if you want to develop at the core level, this requires a lot of understanding of protocols, security, game theory, and adversarial attack thinking.

Feel free to reply with more questions so I can guide you better.
Overly simplified explanation: You have to have a buyer willing to purchase at that price. Lets say the exchanges set the price at 100k when 3 minutes ago it was 15k. No one would buy.

A lot of the market movement is caused by people setting fixed prices on their transactions. Eg: Sell 5 BTC at X Or buy 5 BTC at Y. If X or Y is never reached the transaction never takes place.

Generally the exchanges just connect a buyer to a seller. You are not buying the exchanges coins but rather the coins of another individual/trader. The exchanges are just middle men facilitating the sale.

The exchanges make money on a per transaction basis on fees. If the market grinds to a halt because there are no transactions the exchanges make no money.

Now there are many possible reasons for the recent spike, some malignant such as potential pump n dump scheme or artificial inflation due to the upcoming futures exchanges and the desire to profit from shorting and some benign such as all the media attention and fear of missing out or just genuine belief in the potential of BTC as a currency or asset.

No idea which reason is accurate, could be all of them or none.
It's not hard to imagine if you've ever looked at running a marketplace. ;) The one reason I'm not throwing stones yet is that the laws around money transmission are state-level and very weird and there's the possibility that they're trying to avoid getting slammed by then. Also, Stripe might have a beef with their bundling, too.
Yah like doing 25k a day. That could cause problems.

The big question now is, what happens when somebody sells big for dollars. This would be an excellent time for someone with 10,000 Bitcoins to sell, take their $160,000,000, and go home. Could the market handle that?
Maybe Coinbase themselves does.

Coinbase has market makers though who pay 0% transaction fees. So the makers may take the other side of transactions.
When CB went down for a bit today I had the recent news of NiceHash in my mind. Sure was a breath holding moment.

My point is that instead of standing around crying about how terrible it is that people need to take predatory loans (and it is terrible) we should work out how we can change things so that they don't have to. My suggestion is to work with a proven mechanism - the welfare state.
What's the question? I assume you're asking if Coinbase actually buys BTC when you ask them to? Coinbase isn't publicly audited as far as I know so we don't really know. A related question would be... what fraction of Coinbase customers actually send or receive bitcoin, and what fraction of Coinbase customers simply buy and hold bitcoin that never goes anywhere. With this question answered, we would know how much Coinbase needs to actually execute on trades, and how much Coinbase could simply take the customers money, claim BTC ownership, and then not actually transact BTC.

I assume exchanges have some way of signalling options to each other but I don't know what that is.
Thank you. This is a ton of thankless work and it really helps with organizing web surfing.
This is assuming that everyone is paying $1 across 50 different artists.

The question here really is - What is the distribution of backers and payment amount on Patreon?

If majority of their customers are, 1:1 ie one patron to one artist for $1. Then it is an issue which payment processor needs to look into.

But, if it is 1:50 ie one patron to 50 artists for $1 then I am sure Patreon will be creating a batch transaction.

Patreon's problem surely stems from the fact that 1:1 is more likely true.
Well nyt saw it by proxying user traffic. You could do the same with a chrome extension, similar to uBlock.
This approximation has vanishing error from a linear function (as the interval decreases) and (most importantly!) we only have finite noisy samples; so it’s essentially indistinguishable (in a statistical way) for a small enough interval given some variance.

There can be a market with only buyers or sellers. There is just no execution.
Gold is tangible and definitely has real world applications. Shares are backed a legal system tying them back to the real world corporation and it's assets.
