Many sales taxes also exempt necessities, like grocery items and clothes under certain cost ($100 per item). I was surprised that when I bought clothes at a not-inexpensive retailer in NYC recently there was no sales tax.
Those buses in the US tend only to be 60 feet long.

To put this in perspective, the longest single tram unit is 183 feet long in Budapest: https://welovebudapest.com/en/2016/04/14/budapest-now-has-th...

And because trams are basically just street legal trains, they can be coupled together like a tram. Seattle eventually plans to couple 4 96 ft units together, for a total length of 384 ft. You couldn't run a bus that long safely in mixed traffic; trams are able to do this because the vehicle is fixed to the tracks.
Before inquiring whether something can be made accidentally, perhaps one should determine if it can be made intentionally.

That is, can organic chemists create functioning RNA from scratch? How about a strand of DNA? (And, by scratch, I mean starting with components that were not derived from living organisms.)
Thanks for the links; great study material.

"creates divisiveness and polarization through majoritarian voting"

FWIW, we use Approval Voting for our most contentious decisions (endorsements, resolutions). It's been super effective and we now have fewer friendship ending arguments.

Alas, we still have to suspend the rules each time. I'm hopeful that eventually we'll amend our bylaws to make Approval Voting more the norm. Change is hard and bringing everyone along takes. so. much. effort.

Walkability is a proxy for whether a city has a knowledge economy (closely packed buildings) or an industrial economy (large warehouses and factories, less walkable). The knowledge economy cities have far outperformed the industrial cities in economic growth over the last four decades.

Investments aren't just a number on your trading account, they're property. Rich people also invest in property through real estate investment trusts (REITs) which profit when people pay rent in those buildings. By not taxing rich people as effectively as we tax the poor (via sales taxes), we enable rich people to own more of the society we live in and levy rents on poor people.

This is called the Greater Jihad in Islam.

Condition of Arjuna as he stands in the middle of the two armies and gets chided by Krishna is called "Wavering" and addressed in line four of Hexagram 1 (Ch'ien).

A place of transition has been reached, and free choice can enter in. A twofold possibility is presented to the great man: he can soar to the heights and play an important part in the world, or he can withdraw into solitude and develop himself. He can go the way of the hero or that of the holy sage who seeks seclusion. There is no general law of his being. If the individual acts consistently and is true to himself, he will find the way that is appropriate for him. This way is right for him and without blame.

One day humanity will recognize the unity of the spiritual heritage of Humanity. It will be a good day.
Checks will be around for a while, especially for B2B transactions in the US. Checks are the easiest way to move a large amount of money with minimal fees. Accounts payable departments already have their workflows setup to use checks. Also, banks don't make it easy to do transfers. ACH and wire transfers can take as little as 24 hours, but some banks don't expose this functionality on the web to make the transfers easy to initiate.

The Federal Reserve conducts a triennial payments study to track the number and value of non-cash payments made by U.S. consumers and businesses. The 2017 annual supplement[0] reports that checks account for approximately 17.9 billion payments worth an estimated $29 trillion dollars, give or take a few million. Unsurprisingly, these numbers are trending down over time; however, according to a 2016 survey published by the Association for Financial Professionals [1], 51% of B2B payments are still made with checks.

Uber did not just offer cheaper taxis. A taxi company has staff and cars that cost money to own, run, and maintain which effectively means a taxi company any never meet peak demand and make a profit.

Uber can meet demand since they don't own the cars nor the staff. The system automatically scales, something taxis can't do.

That is the innovation, not apps. Plenty of taxi companies all over the world had apps before Uber even existed.
Hmmmm… The danger in the constant back and forth of poor nutrition science being hyped up in the media, reversing last week’s headline, is that eventually the general population just gives up, and stops listening/acting on ANYTHING coming from this expert group.

Those who want to drive food guidelines by other factors than actual health, should be honest about their motivations, whatever they are, rather than claiming that they are scientifically/health driven. Arguments for animal welfare, water use etc need to be backed by good science as well, not just platitudes. I’ve had people try to make the argument to me that all the water falling on all the pasture land in the US needs to be ‘counted against’ meat. That because we treat some animals poorly, we should stop eating all of them, rather than asking why we treat them that way, or how other countries might be doing it better. I’ve yet to see a good study on the millions/billions(?) of small animals that are killed in millions of acres of U.S. monocrops, but I’m guessing it would be eye opening. For every warning statement on animal CO2 use, I can find a seemingly well done study on positive CO2 capture by regenerative farms (i.e. traditional farms before feed lots). Carnivores on Twitter seem to have had amazing individual successes getting rid of their own specific inflammatory diseases, but then often assume that experience can be extrapolated to everyone, and often discount the long-term health impact of zeroing out plants completely…. It goes on and on.

Lastly, my statement about eating like my grandparents used the words “I” and “my” and was obviously my own rule - hard to imagine what you found ‘uncharitable’ about that statement. I’m somewhat new to HN - are we not allowed to share our own experiences here?

One of the advantages of the combination of 120V, ground wires and keyed plugs is that by and large electronics here have not really needed to be unplugged between uses by most people still living.

In fact the most likely vector to shock yourself is the plug on your vacuum cleaner, because it is so often plugged in and mistreated in the process. The materials and stress relievers have gotten better and it’s probably been 30 years since I’ve seen a frayed cord...

GDI.

If FillRect(hdc,rect) is the only thing that you need from it then it will work for you, yes.

But GDI does not support antialiasing so, let's say, Ellipse(hdc) will just draw an illustration to Brezenham algorithm but not that you would want to present to the user.

Same thing about alpha channel - no transparency in GDI.

So forget GDI for UI purposes. You may try to use that GDI+ horse... But it is pure CPU rasterizer and so forget it too on modern high-DPI monitors.

Yes, GDI is still with us but the chorus is here already to sing "Sic transit gloria mundi".
In 2016, state and local governments spent $175 billion on highways and roads [1].

Fuel taxes, sales taxes, and usage fees (tolls) generate roughly $150 billion per year.

Excise taxes do not even have a good national accounting system and I can’t find a US total number. But, for example, just CA generates roughly $10 billion in revenue from these fees.

Far from not covering the costs, the direct taxes and fees on cars are actually generating a profit.

If you want to talk about externalities you have to account for both positive and negative externalities.

I'd need some expansion on the statement that media is government controlled. Yes, they are beholden to what the government is willing to tell them, but investigative reporting often digs up more. I have a hard time believing they're government controlled when at any given time, the government in power is faced with a large media segment that is biased against their political agenda.

If there is some level of control, it is at the complete opposite end of the spectrum from the strict authoritarian control of media in many other countries, so it's still much more "free" than many alternatives.

Lots to see when we find correlation, even if we aren't certain of the causation.

First and foremost, we should attempt to replicate it and see if the correlation holds up independently.

Second, we should attempt to determine if their is a causal relationship. The arrow of causality going in either direction is of great interest to urban planning.

Or third, if there is no causal relationship between them, we should attempt to determine whether there is a third correlating factor, or better still, another factor that has a causal relationship with these two.

This discovery is highly interesting, and points in the direction of useful further research to perform. I would definitely not say that there is nothing to see here.

Authors often do some research, and then present some conjectures. Their conjectures may not be supported by the research, but they point in the direction of further research to confirm or refute the conjectures.

Research like this may not be sufficient, but it may be useful.
I think Wellerstein reads more into what Oppenheimer said (years later) about what he thought when he saw the explosion than what he may have meant. My take is that Oppenheimer was saying the quote from the Bhagvad Geeta accurately described his thoughts at the time. That with the atom-bomb we (the United States) have (the power to) become the destroyer of the whole world. I think what he said about Vishnu and Arjuna was to merely provide the context of the quote. He did not mean imply anything about his own duty. This is borne out by what he says next: “I suppose we all thought that, one way or another”. No matter what their personal motivation may be for working on the bomb, they must all have sensed the enormous destructive power of the bomb.
Not really. A model (after training) continues to be as plastic as it was before. Correspondingly, it can be made to "forget" what it has "learned" and learn something else. [At least architecture-wise. Whether the learned parameter values reduces plasticity is a non-trivial statement that needs to be demonstrated]

If contemporary AI/ML models behaved like what Alison Gopnik says, then their tendency to overfit would be even more of a problem -- you couldn't even transfer them from simulation domain to reality -- since they would lose all their plasticity overfitting to simulation!

Also, this article contains lots of other interesting ideas to think about. Highly recommend reading all of it.

Where I work we move a lot of money around via ACH (which might as well be via cheque). We treat the account number as a secret and encrypt it because here in the US the extent to which a bank needs to authenticate the source of an ACH transaction is largely left to the discretion of that bank.

We're integrating with a company in Germany that is confused by our request for their public key (so we can encrypt the account numbers on capture for their eyes only). As it turns out, in Germany it's common to share your account number on your web site so that your customers can more easily pay you. They have an authentication step that is separate from the account number.

This of course makes our system look pretty silly. We give account numbers to everybody we write a cheque to, but then treat them like private keys in other contexts.

Maybe this is to be expected, as ACH and SEPA (which is the equivalent-ish system in the EU) are separate systems after all, but further research shows that there are other regional differences within the SEPA network re: whether the account number is a secret.

If we had a competitor trying to do the same thing with a system where authentication and addressing were both separate and part of the protocol (e.g. any cryptocurrency), they'd be done by now and making money. We've been at this for more than a year and we're getting nowhere.

The moral of this story is that cheques may not be obsolete yet, but the protocol that backs them will probably soon be. It has fundamental flaws that open the door for fraud and incur other overhead costs as well. Once there is a viable competitor it doesn't stand a chance.

They're also changing the nature of the commercial relationship from buying to renting. Stopping the subscription stops access to many essential features, no matter how much one has already paid.

From reading the comments on this story, it sounds like there are already (profitable) competitors like Spaces that are easily copying the WeWork office format. If this is the case, it doesn’t sound like WeWork has much of a moat.
By and large, most "downtowns" are primarily knowledge economies whether or not there is a lot of industrial economy centered around a city. If for example you look at the jobs in central Houston or Dallas I think you'll find they are mostly office jobs but those, like many other US cities, are not very walkable except in very limited areas.

So they buy/beg data for 382 "community zones" from walkscore.com, do linear regression, and find a correlation. Then they get funding to do an individual-level survey and there's no correlation. And it doesn't appear in South Korea either.

Their explanation is some statistical magic to pull out a "sense of belonging" as a mediating factor and a statement in the conclusion that "It may be that walkability is an emergent property most clearly visible at the level of aggregate, not at the level of each individual."

No discussion of data accuracy besides noting that even perceived walkability and actual amount of walking are barely correlated in their surveys (i.e., their data sucks).

Interesting paper idea, but the implementation seems like more statistical garbage.

This kind of stuff should be forbidden, but unfortunately, it's left to universities to regulate themselves. Some have guidelines that say don't take research funding from the tobacco industry and other industries, others don't.

What is ironical, is that this new study DID conclude that there was a link between chronic diseases and consumption of red meat, just like the others before it, it was mostly dog bit men news. But of course, mainstream media didn't read it.

They only read the incredible conclusion, that said that its was not worth for meat eaters to stop eating meat to improve their health, since they like it so much!

One of the authors of one of the studies came out and said that this was the most outrageous abuse of data that he ever saw.

Without using their software, and just going based off of screenshots, I don't see anything that couldn't be ported to Qt fairly easily.

Now if there is a lot of intertwined code that makes the UI less portable, that's another issue, but I currently don't see how their UI layer could be so complex as to not be easily shifted to Qt.

The cross platform nature alone would be worth the cost in my opinion.
We had a toaster where the side carriage broke and tilted over to the side and let the bread come into contact with the heating elements, there were some flames from the bread (and lots of smoke) but not enough to make me think the kitchen would burn down... I just yanked the cord out of the wall and pulled the toaster into the sink but in retrospect, I don't think even that was necessary, the bread was already pretty much burnt out.

Moral of the story is -- toasters are heating devices, so don't let them run unattended.

At this point, I just pay the fees and hope technology improves enough to have ubiquitous choices.

> The danger of computers becoming like humans is not as great as the danger of humans becoming like computers.

-- Konrad Zuse

Another man very much worth reading: https://en.wikipedia.org/wiki/Joseph_Weizenbaum

> His influential 1976 book Computer Power and Human Reason displays his ambivalence towards computer technology and lays out his case: while Artificial Intelligence may be possible, we should never allow computers to make important decisions because computers will always lack human qualities such as compassion and wisdom. Weizenbaum makes the crucial distinction between deciding and choosing. Deciding is a computational activity, something that can ultimately be programmed. Choice, however, is the product of judgment, not calculation. It is the capacity to choose that ultimately makes us human. Comprehensive human judgment is able to include non-mathematical factors, such as emotions. Judgment can compare apples and oranges, and can do so without quantifying each fruit type and then reductively quantifying each to factors necessary for comparison.
