The standard deduction ($0.58/mi) is very high. The marginal cost of driving depends on how much you drive. Driving the US average 15,000mi/yr, you can buy a nicely-equipped Mazda 3, insure it, fuel it (at CA gas prices), and throw it away when the standard warranty expires every 5 years for $0.53/mi.

This cost is dominated by the production of the car and goes down almost linearly to something like $0.25/mi before maintenance would even be an issue.

This is cheaper than almost any other form of transport.

The road system is essentially free at this scale.

There are no significant subsidies that make this possible. It's just that cheap. And most of the cost is production – a positive-sum activity.

A congestion charge is a transfer payment (zero-sum). In general these should not be expected to significantly impact the value of civilization.

For one thing, the economy tends to route around them. A mortgage interest tax deduction causes house price inflation, for example. It's not clear there should be any long-run sensitivity of commuting times to commuting taxes. People are already paying their hourly wage to commute, and they will pay any tax on it also with that wage...
Looking at it closely I think it gets particularly gruesome when you try to do a "perfect" job of determining people's preferences.
For Mobile, I didn’t know what I was looking for. The Navigation bar should be fixed to the top.
A wild idea already decades past it's prime:

in addition to the odometer, include a chronometer: something like "hours driving above 5mph". Then tax on a combination of those.

That seems like it would have been be able to implicitly price congestion into a progressive use-based tax.
This is really great idea. Today I don't trust the journalists, but if they provide references atleast there is a bit a scope for trusting a particular article. ofcourse, provided the references can stand the scrutiny.
It's like it's 1992 all over again. Every change requires changing every caller everywhere. Yes, it's an improvement now that the typechecker will tell us all the places we need to change but it still doesn't sound enjoyable or useful.
You are describing Scrum, not Agile. Scrum is a subset of Agile. There are many other Agile methodologies, including what the go outlined.
That's true, but it only solves one side of the problem, where unqualified people won't get hired by pure networking. If people only get hired by networking plus performance, it still means that capable people who are pushed out of effective networking (for any of a host of reasons) will lose opportunities. They might not get bad recommendations, they simply won't be on anyone's list to call.

Even worse, it's quite possible for discrimination to become a disincentive to recommending someone, just like incompetence would be. Someone who won't be well-received for personal reasons is effectively a "bad candidate" with the potential to damage the recommender's reputation. The result is that even a person who overcomes barriers to find network connections won't necessarily be able to draw on them effectively.

(A past-tense example to cut down on politics: a Liar's Poker trader wouldn't recommend a friend who couldn't sell, but they also wouldn't recommend a skilled trader who wasn't a friend. And if they had recommended a skilled friend who wasn't a white guy, they could have expected at least as negative a reaction as if they'd recommended a bad trader.)
Ask HN: Tools for building high performance REST API in 2019
Hi HN,

I was wondering what tools can I use to build REST API from scratch.

EDIT: I was planning to setup my own server. Have an API gateway and use PostGreSQL.

Thanks,
Somewhat related, I find it unusual that a lot of SaaS companies get you to choose a subdomain during the trial signup process. Sometimes I just want to try out a service and kind of feel bad squatting on a somewhat premium subdomain so easily. I’m launching a product soon and it made me think about different ways to handle this, especially wrt to shorter (more premium), and trademark/brand related names.
> Bringing the intolerant into your tolerant fold is self-defeating.

So you don't think we should allow Muslim immigration? The Islamic religion has many intolerant precepts, so by your argument we should not be inviting it into our tolerant societies.

> There is a big difference between tolerating people who have views different to your own and tolerating people who actively want to put an end to you and your views.

Is there? I don't see a difference at all, as long as violence is not part of "putting an end to you and your views".

> How tolerant are you of the views of ISIS? Or the KKK? Or Combat 18?

I'm tolerant of any view that doesn't call for violence. ISIS should be fought because they are violent, not because they have intolerant views. The KKK and Combat 18 should be fought when they engage in or call for violence, not because they are intolerant of non-whites.

There's no grey area here, the dividing line of what constitutes tolerance is quite clear: violence and inciting violence is unacceptable, and anything else is permissible free speech that should be fought only with speech. That's the very bedrock of peaceful democratic republics.
Kanban is currently all the rage.
I was hoping the current homepage had that function, with a list of special features followed by some examples.

You want it shorter? Something like "Get Python-like ease of use together with static typing and speed and built-in game programming functionality" ? That really doesn't do it justice. In the end, like most languages, it is a particular cocktail of trade-offs, and to see whether this suits you, you need see the full list of features.

Maybe you want a list of features with an example for each? It's hard to make it short though, especially the type system.

As a European? What does that mean? It's not like it's a homogeneous continent?

Also as a European ... actually as a human ... I'd very much prefer to prohibit anyone spying on me. Europeans have seen first hand what totalitarianism means, even if it masquerades itself as freedom ;)
The cost structure of most roads is that the cost is in having them exist independent of how much they're used. Most of what causes road maintenance to be required is weather rather than traffic. Moreover, if you have an empty road that nobody is using, you can't save up the unused capacity and use it later.

And as for the environmental damage, that is clearly the bailiwick of fuel taxes rather than congestion pricing.

So the only thing congestion pricing could be good for is to reduce congestion, i.e. suppress demand. But you don't want to suppress demand -- you don't want people to stay home instead of patronizing local businesses etc. The problem isn't too much demand. Demand is good. The problem is insufficient supply.

In some cases, particularly in suburban areas, when there isn't enough supply you can solve it by expanding the roads. In urban areas you typically end up with alternatives like increasing housing density near mass transit hubs, to shift the demand away from the roads because there isn't space to expand them. But in any case what you want isn't to eliminate the demand, it's to satisfy it somehow. Because once you have enough supply to satisfy the demand, you no longer have congestion.
Cool platform. One suggestion - create a unique url/route for each article. I wanted to send a particular article to a friend, but realized there's no way to provide a unique link.
The title of the paper is "Helical orbitals and circular currents in linear carbon wires"...

... but they do refer to them as "promising candidates for novel applications" which indicates actual applications are a little way off.

Incidentally, although it's easy to write these molecules in text (like C=C=C=C=C=C...) that does not really show the helical orbitals.

https://pubs.rsc.org/en/content/articlehtml/2019/sc/c8sc0546...
Is there another source other than the "street" that this can be compared with? The implication makes it sound like the street as a source is the problem, but there's no other source mentioned.
> these molecules might be candidates for spin-selective transport and/or sensitivity to magnetic fields (...) We hope that at some point these quantum effects can be used in electronic devices which are nothing like the ones we use today.

Basically they're hoping to achieve some form of novel device, not replace existing components.

This isn't without precedent - we have examples like Hall effect and giant magnetoresistive sensors. Both of these went from "weird quantum phenomenon" to "everyone has a device in their home with a component built on this tech".

I don't think the effect has been definitively proven one way or the other. While there are studies showing a decrease in congestion, there are also several showing a notable increase too[0][1].

I can say, anecdotally, in SF there are lots of Uber/Lyft drivers who drive in from outside of the city (and even Bay Area) because they can make more driving in the city. If they disappeared, would they be replaced by an equal or greater number of private cars? Given the parking situation in SF, I doubt it, but who can say.

So the old thought about cancer was "every cancer will grow and kill the patient so we always want to find the cancer early and treat it before it spreads"

Turns out that's not accurate, and its complicated, and we are still learning.

There's three types of cancer, birds, turtles, and rabbits. (I didn't make up this terminology, see links)

The birds have already flown away and left the barnyard, early detection isn't going to help.

The rabbits need to be contained before they hop away, if we shut the barnyard gate early enough we can prevent their escape. These are the cancers where early detection is useful and saves lives.

The turtles just chill out, moving so slow that they never escape. These cancers cause no symptoms and will not go on to ever harm the patient and may even resolve themselves over time. Finding turtles is bad, treating turtles causes very serious side effects (cancer treatment isn't exactly benign), wastes time and money, causes anxiety, and doesn't reduce mortality one bit.

We've discovered there's a lot of turtles out there.

Of course, once we find early stage cancer we usually treat it like its a rabbit, even if its destined to be a turtle, because a lot of the time we can't tell the difference.

South Korea is finding this out the hard way, aggressive screening for thyroid cancer has produced a TON of thyroid cancer patients (15-fold increase (!) over the past 20 years) but ZERO reduction in thyroid cancer mortality.

Yeah, but these are all a certain cultural bubble where they are vastly over-represented.

EV's were 2.1% of new-car sales last year in the US. That's nearly doubling the 1.2% share from last year, and that is great growth.

But that still means 98% of new cars last year weren't. And with the average car on the road being ~12 years old, EV's are still practically a rounding error in the actual vehicle fleet.
I don't get why China is taking these extreme measures. I know there's a general feeling of anxiety towards Muslims (I'm Muslim) and I understand that China worries about these sorts of cultural issues. But this is really heavy-handed. Can someone explain this to me?

Of course, I should make clear that I completely condemn this type of behavior from any country. And point out that letting China get away with this means many other countries will do the same.

It's pretty obvious what the most well-known trademark is. I don't think Google would be giving ibm.dev to the International Brotherhood of Magicians [1]. Here's an example as it pertains to domain names [2]. Of course Instagram is different and there's much less oversight, but they would probably do something similar, where they first verify a trademark, and if multiple parties have the same word in the trademark, determine which.

"2.5 Does putting my trademark in the Clearinghouse mean that I automatically get my trademark as a domain name in all new gTLDs?

No. The Clearinghouse verifies and maintains information from many jurisdictions and classes of goods or services, and many parties may have legitimate rights in the same trademark. Allocation of domain names in a particular TLD occurs according to the registry policies for that TLD."

> In particular, I think Tesla may be well positioned in terms of autonomy. Although Waymo and Cruise might have a more robust approach, they are taking their time.

Waymo has full self-driving in limited public commercial use; there is no way that they can be charscterized as “taking their time” compared to people marketing less than full autonomy now with promises of full autonomy at some unspecified time in the future.

> I see that Tesla is very serious about bringing the benefits of autonomy to market across all their vehicles.

I see that they are serious about selling vehicles today based onpromises of full autonomy tomorrow; it's less obvious they have the combination of seriousness and competence to actually deliver on that promise.

That's because back in the day, Unix was designed for hackers to mess around and play games, while VMS was designed for actual production workloads (and Windows inherits this legacy).
My only strong opinion is that I'm completely unqualified to opine on this as a white american westerner. When the Dragonfly outrage was happening within the company, many people stood up and helped kill the project (by leaking, by complaining internally, by refusing to work on it, etc.). But the Chinese nationals I work with weren't particularly pleased with all the westerners speaking on their behalf. Obviously my sampling doesn't represent the population, but the general attitude was that Baidu is woefully subpar and denying access to information, censored or not, was against Google's stated mission.

Believe me, I'm greatly disturbed by China's censorship. Talking shit about my own government is a right I can't imagine losing, let alone access to the treasure troves of anti-US thought. I also know how terrified I would be if my own government had the ability to lock down information. Imagine Trump and the GOP having that power, even for 4 years, and what damage they could do. (And GOP voters would make the same argument, of course, the other way around, and already do fear that tech companies are censoring their freedom of thoughts).

So believe me, I'm not trying to defend China here, nor am I trying to shill for the project. But it's not my lane to opine on, and I had hopes that if the project did launch, that some good could come out of it. But your concerns are absolutely valid too.
I think a lot of the debate here lies in the gap between "vouch for" and "recommend".

In that era, you could often just ensure that the BIOS could load the bootloader/kernel by placing it into the region still reachable by the BIOS. OSes like Linux (and anything Windows NT based) practically completely disabled[1] the BIOS anyway, and their own IDE drivers would be recent enough to understand how to address the full disk.

It was not uncommon to have a small boot partition at the beginning of the disk for that purpose.

[1] Bit of a simplification. In reality, the BIOS being 16bit real mode code meant that you had to jump through very elaborate hoops if you wanted to use it in your protected mode OS in any way, and then for questionable gain.

Traffic itself is a symptom of roads being free in the first place. Charge drivers exactly what it costs to maintain them plus a small profit and suddenly there will be little traffic and no major potholes. Taxpayers will get all that money back too, and they can either spend it on driving fees or they can save the money if they use roads less.

Actually, your "decomposed" version still has clusters that are different from the individual characters making them up. There's क्, which is क plus ् (OK, that one's easy); more significantly, you've left त्रि as a single unit whereas it is made up of त + ् + र + ि.

So "spelled-out", क्षत्रिय is made up of क ् ष त ् र ि य . I don't know if Unifont tries to render the combining characters as zero-width overstrikes, or what, but much more than that is needed for a readable result.
