At this gas station scenario, you have two transactions - the preauth, verified by the card, with a specific limit; and afterwards a transaction (not verified or even seen by the card) with the actual amount.

The former is something that the card/phone can show and verify, as that is the actual amount you're authorising, even if you don't "spend" all of it.
If you mean the [IMAP]/Read kind of labels then yeah it handles those properly.
I think he pointed to the need of having something similar to expected utility maximization in the context of a theory of rational decision making.

I guess it's true that one can also have economic theories which are not compatible with rational decision making as understood in EUT so they could be completely different.

> claims that, in the usual formulation of EUT, it cannot

EE claims that, but it's a baseless claim. The growth optimization arguments used by EE can be perfectly used (and have been used) in the usual formulation of EUT. If the agent has a preference for growth that can be described with a utility function.

(I agree that EUT doesn't explain all behaviour. EE even less, being even more restrictive.)
Microsoft was aware of the vulns for 2 months before issuing a patch.

Some of the vulns existed in the Exchange codebase for 10 years.

Microsoft faces perverse incentives. When their customers get compromised, Microsoft benefits from accelerated upgrades and cloud subscriptions.

Yet their customers blame foreign threat actors and not Microsoft, so Microsoft suffers no reputational damage.

With these incentives, why would any rational corporation spend resources hardening their software or responding rapidly to new disclosures?
There are always tradeoffs. Does this point to an inherit flaw in the decentralized nature of bitcoin?

That is, if I agree that mining is wasteful and bad for the planet, who do I call about that?
> just an unfortunate state of affairs

Why do you think a state-sponsored broadcaster would have been equally likely to pick up this content?

Self-interested companies don’t have geopolitical concerns.
Go here: https://bitinfocharts.com/

Click on eth, see that the ethereum chain is 630 GB.

I don't know what you mean by "these are not full nodes".

> Not trivial when you take into account that to assure decentralization the nodes must also broadcast the whole blockchain. Compare the costs of having to broadcast a 6.5tb file for an average of ~30 nodes per month. It will probably cost >$1 thousand. Not very acessible.

Miners broadcast blocks. These numbers you have are made up. Your chain size is off by a factor of 10. Full nodes just help with whatever bandwidth they have. Only the miners really have to send out blocks and sync with the chain. I don't know where you are coming up with your ideas of sending out the full chain every month, 30 nodes, or the cost.

A $10 vps can cover the bandwidth of 1000 people syncing with the chain. You can get gigabit connections with multiple terabytes for that much. I think exchanges and miners can handle that, not to mention anyone with a cable modem. There is plenty of headroom, there is no centralization from bandwidth or anything else. Only in cryptocurrency do people think a gigabyte a day in bandwidth is a problem while the average person is streaming multiple gigabytes in youtube, netflix and steam games every day.

> Sure, you could use another crypto that incorporates the same trade-offs as Lightning Network.

Other currencies don't have the trade-offs of a second layer. You make a transaction, you see it show up. Only bitcoin and ethereum have expensive transactions. Everything else works.

> the network effect is already building around Bitcoin

Bitcoin's average transaction fee was $31 a few days ago. The average transaction value on bitcoin's chain is over $411,000 USD. There is no network effect of bitcoin because it has been crippled.

> I don't run a full node. That's up to the community to decide.

I asked you where you got your numbers and how you came to your conclusions. You said "I don't run a full node. That's up to the community to decide". That doesn't even make sense as a response, let alone answer the question.

> There is no easy answer as you are seemingly implying.

There are easy answers, don't use chains with expensive transactions. Don't use chains that refuse to scale. Bitcoin refuses to scale because the people that took it over want to sell a second layer that solves a problem (poorly) that they created.

There is no real problem here. There is no reason cryptocurrencies can't scale to many orders of magnitude more transactions. There is no reason to pay money to use a second layer.
This bizarre construction popped up last week in an article about the New Zealand quakes:

I'm the author. My testing methodology was to run the round-trip latency test using OboeTester: https://github.com/google/oboe/tree/master/apps/OboeTester/d....

It's a simple test: produce a tone (either on built-in speaker or over wired headphones if using a loopback dongle), measure the time it takes for that tone to reach the audio input.

For devices which I didn't have access to (our team has a limited number of test devices) I used the figures from Superpowered, but with some assumptions/rules:

#1 If AAudio was available on the device I used the measurements from that rather than OpenSL ES
#2 No measurements from custom ROMs
#3 I used the measurements from the latest version of Android which the OEM had released for that device. For example, if a device was originally released with Lollipop but it was possible to upgrade to Marshmallow then I used the figures for Marshmallow.

For touch screen latency measurements I used a WALT device (https://github.com/google/walt)
The real power imbalance is the Central Bank's power to confiscate wealth by inflating it away aka money printing, and not to forget the confiscation of physical gold by the US in 1933 (thanks FDR). There is a reason why countries decoupled from the gold standard to fund WW1. They got near infinite access to the nation's wealth. The loser of WW1 ie Germany eventually suffered hyperinflation, as have countries like Zimbabwe and Venezuela recently. Should Governments have the power over your money to the extent of making it go down to zero? That's what happened in all of these cases.

So no, BTC != USD
For offshore wind farms, typically only very long export cables are HVDC, or long interconnector cables. Inter-array and export cables up to around 100km or so are AC.
I'll reuse an argument from another comment I made: sure, let's accept that we need to treat housing differently because people need housing. Should we do the same for food? People need to eat as well. Does that mean we should factor in the cost of arable land into the CPI?
I think it's possible for both statements to be true at the same time.

A small company with a successful, functioning project is getting a little bit of traction when Google crashes into the market. Google bids up staff costs, uses free advertising to get customer mindshare, scares off the small company's possible investors, and acts as a huge distraction.

After stumbling around for a while, Google gives up, but in the meantime, they've put the small company out of business.

Of course, the small company might get extra attention which they can use to their advantage, but it will be hard.
> If we could get all the major mining groups to dismantle some % of their machines, we could reduce energy consumption with a very small cost to the group.

The whole point of BTC is that you cannot trust each actor. If we could coordinate a population of trusted ledger managers, there wouldn't be a use for a blockchain in the first place.

Yes please. Ive been trying for weeks to buy a gpu.
Not only is the style bad. The journalists all seem to have a rather narrow and uniform political agenda now. I don't see any suspicion of large, centralized projects, the way they used to be suspicious of these things in the past. Its enough now it seems for a political group to declare that there is a particular purpose for a policy, and the policy is analyzed strictly from the perspective of its goals ... nobody seems to talk about tradeoffs and other possible outcomes in any great depth.

Which is tragic, given how failure prone almost every Federal grand program has been in the long run, from the war on drugs, to the war in Iraq, to housing subsidies, to subsidized student debt.
I'm thinking maybe the solution would be simple as they'll just need to raise the platform and other areas by building up. The mostly empty land is not used for anything and allows for explosions without causing harm to people, they can be under water (maybe). You can raise the roads going to the platform too.
I don't see any software produced today approaching the level of user-centric productivity and speed one can get out of (keyboard only) Excel. Is software like this just not being produced now?
Sure, but what does Pearl bring to the table here? The idea of making falsifiable predictions long predates the "Causal Revolution." The warning of "correlation is not causation" still seems as relevant as ever.
Not really. The higher the volts, the fewer amps and losses. So, if you can just get the voltage high enough, there's really no limit.

Not sure what the current highest volt transmissions are. Maybe a couple million volts on some DC lines? But I think that's good enough for hundreds, if not thousands, of miles of efficient transmission.
It's truly a pointless article, but that hasn't stopped tens of people from spitting out the same arguments about bitcoin that you see in every HN thread.

But it is pointless, and distracts from quality signals in the interviewing process because it's often weighted disproportionally to its importance.

Twice weekly seems excessive, but I only ever see them in the peak of fall when the leaves are falling. I blow my yard maybe 4-5 times all year combined.

Creating a Dancing 3D Avatar Snapchat Lens
1. Build something
2. Offer it for free (e.g., "register now and get a 3 months trial period for free!")
3. See how it goes
4. If after 3 months enough users are still using your product regularly, then incorporate and start charging.

In my opinion, it's not worth to setup a business if you don't know if your product wil actually be used or not.
I used to have this approach, but when you start to take deps into account, it is often preferable to have a medium amount of code in your own codebase (that eliminates some bulky deps) to a small, fast, clean/easy to read in full codebase that depends on some large external libraries that bloat the overall size of "lines of code in use in this application".

Now I am a dependency minimalist (as much as is practical, it's a continuous gradient trade-off and naturally YMMV) more than I am a pure code-written-here minimalist.

I'll happily double my SLOC for most small apps if it means my app can be stdlib only.
I can't believe grandma is so oblivious to security she'd just blindly download and build a random tarball without manually inspecting the code for backdoors.

It would be cool if they built a full-scale prototype of their proposed methane/oxygen propellant plant near the launch site. It would be harder to pull CO2 out of the atmosphere on Earth than on Mars, but on the other hand solar power is much more abundant here.
Exactly. Fossil fuels and rare earth metals are already considered to be a national security risks. Depending on a currency with huge energy requirements only multiplies this risk, which further incentivizes war.
I'm a light skinned male. I'm also a Choctaw Native American. In my senior year of college in 2004 I applied to dozens of companies. I never got a single response.

I decided to try an experiment - I applied to IBM and, for the first time, I selected "Native American" as my ethnicity. Within 24 hours I got an email inviting me to a special, all expenses paid IBM recruiting event held for Native Americans in Albuquerque, New Mexico. They followed up with several phone calls encouraging me to attend.

I didn't want to go because I felt like the only reason they wanted to talk to me was so they could add another number to their diversity report. My Dad convinced me to go.

They had Native American speakers, food, performances and music. It felt so condescending.

On day 2 they had hiring managers from dozens of departments. It was like speed dating. One manager asked me "What was it like growing up Native American? Was it hard? Tell me about how hard it was for you." It felt gross.

One hiring manager handed me an offer letter when I sat down. She hadn't even spoken a word to me. She told me she had reviewed my resume and that was enough. WTF.

I got several offers from that event. I turned them all down.

I ended up getting a job at Microsoft. They didn't ask me about my race when I applied.
seems less like a market problem and more like a government problem
Glad I'm not the only one. My vision isn't bad but the way the black pieces are shaded and shaped makes me have to put conscious effort into identifying them. (Not that I'd be able to beat this thing anyway)
Hmm. But the ledger is the solution to that problem. You hand someone the sequence of bits, the ledger authoritatively rules that they are now the holder of those bits, and not you.
Clearly the next step is to move NAO to the blockchain, so we can play nethack in the most immutable and verifiable way possible!

I think it actually is very true in the United States, outliers like SF notwithstanding. US as a whole is significantly more like Plano than like SF. Sure, that does little to make Bay Area residents feel better about crazy housing prices they deal with, but theirs is by far not a typical American experience.
Pretty sure Bitcoin hasn't gotten rid of (or even reduced) the latter..

You're ignoring the fact that the selection of immigrants is not random or a representative set.

If you're right and that an immigrant has to work "ten times harder" to apply for a job, then surely the immigrant population represents a. It would be a damning indictment of America if these people were not more successful than the average citizen - and if you look at the data, they're just a few percentage points ahead of median white people.

And Nigeria and Ghanian immigrants were cherry-picked because those two groups represent largely first and second-generation immigrants, who still largely have wealth and prosperity to go around from these original highly-qualified applicants.

(Also, why do you capitalize white? Usually it's just white-supremacists who do that, so you might want to reconsider your choice.)
I believe that need for the belly flop isn't due to weight but is needed for the higher reentry speeds the upper stage. The current F9 reentry speeds are nothing like what is needed for orbital speeds not to mention from Moon/Mars.

If you are already doing a belly flop for reentry, you might as well do it all the way down to minimize the landing fuel penalty. For unmanned flights you can do it really late even if they crash at a low rate. I would expect manned flights to be less aggressive, especially near term.

...but where Excel really shines and enhances productivity is in combination with that other tool we all love and will never give up, email. Someone emails you (and 10 other persons) some data in an Excel sheet, you (and unbeknownst to you, 2 other persons) update the sheet with some new data and reply to the email, and after a few iterations nobody knows anymore how many versions of the document are in circulation and which one is the most up-to-date. Oh, joy!

If you have to ask ...
Yes, the average of the above for the entire economy. I agree, but the methodology of CPI does not at all match anything grounded in the averaging of the above logic.

A proper measure of inflation should start from the individual level and reason from there.

So if on average 1 loaf of bread is bought by a US consumer and a loaf of bread's rate of inflation is increasing(or even decreasing) by %x, and that's %y of the average consumer's expenditure, then that should contribute %x*%y of the overall inflation rate experienced by the average American consumer.

Clearly this is a complex line of reasoning, but it should be the basis of thought on measuring inflation. Yet, housing and medical expenditure are not even considered in CPI. CPI is a terrible measure that I believe was designed to obfuscate.
Fair enough. But for every bill gates we can find a mark cuban, michael saylor etc who are extremely excited about bitcoin. So I still think it is uninteresting.
Still asking out of desire to learn: How has it been shown to be flawed? With what kind of experiments? Which are the flaws? How to they manifest them self (e.g. how could you exploit them with PoS but not with PoW)?

Some forms of long articles are a form of entertainment. They appeal to a segment of society that enjoys long winded and meandering reads.

But those are different from long articles which pack a lot of content. Time magazine or Newsweek of yore.

The latter didn’t pad the stories with flowery language or add “texture” (things like describing the sofa someone is sitting in and the drapery or wainscoting, etc., that permeates a certain type of writing. That has its place, but not in journalism as much. Long journalism should add direct and proximate information not delve into atmospherics.

Show HN: Anki alternative with integrated notes and study plan
Summary: a blog about machine learning is criticizing the writing in a culture magazine for being too florid. His argument is that all writing, no matter the audience, should be written in a terse, declarative style at an 8th grade reading level.

He attempts to justify this ludicrous opinion by using "Hemingway", a presumably-ML-powered robot copy editor app, to prove that this magazine is "hard to read".
