>What if people didn't try to make money to satisfy their own wants, but to one-up their neighbors in the pissing match of life?

This premise contradicts itself. Wanting to use your money to one-up people IS a want. You’re simply judging what some people might want. I’m not saying some people don’t want that, or that it’s not worth being judgemental about, but it entirely undermines your point.

Most residential ISPs use long lived DHCP leases, and do not issue true static IP addresses.

Do you have an example of an IP address that geolocates to its homeowner's actual address (as opposed to region/city?)

Again, geolocation databases are not magical. This article explains that and some deficiencies:

I think this comment really hits it on the head.

Your medical record is meant to be a confidential record read only by those who are sworn to care for and protect you, and by nobody else for no other purpose.

As a student doctor it's alarming to think that people do not feel they can trust their doctor with their medical history. I wonder if this is particularly a problem with the US healthcare system.
This shouldn’t have been downvoted. It’s an accurate assessment.
There’s no necessary contradiction between those two things. More importantly lobbyists are indispensable because Congressfolk have tiny, tiny staff budgets so it’s not like they have their own internal researchers or even their own legal team. People forming the United States have unpaid interns because they can’t afford better.
Hey if the founder of PayPal can launch his own convertible into Mars orbit, then I can believe in the return of supersonic commercial flight!
This line of reasoning can be used to defend virtually any conduct from a business that employs many people, and that alone should disqualify it from discourse. But in this case the ideal punishment would be unlikely to result in any real damage to careers, just would incentivize Marriot and other hotels to avoid a repeat of this.
The article we’re commenting on specifically says they’ve started assembling a 1/3rd scale model that they hope to fly this year.

I disagree with the rest of your comment, but I see where you’re coming from. But almost every failed aerospace company has a bunch of people with industry experience. Doesn’t stop nearly all of them from crashing and burning. And even the unicorn that succeeds is very late and way over budget.

Guess we’ll see.
What are you saying? Tesla does just fine in traffic, you hit a button on the steering wheel every minute or so to show you are paying attention to the road and that’s it. You are still looking at the road, the readout showing the mapping of what it sees to the real world.

Tesla’s do great in traffic.
He was for it in 2012 and opposed it in 2018 because he thought that the 2018 prop was out of whack vs. the 2012 one. It had nothing to do with "because it was helping homelessness" in 2018.
FLK isn't a diagnosis, but it is a useful clinical impression that might lead to one, even now.
Members and committees have comically small and under resources staff for their responsibilities. Lobbyists are partly a response to that. People who care about an issue pay for research into it and publicise it to all and sundry, congress included.
More intensive security checks have made passing through many airports slower than it was 20 years ago despite e-tickets etc: the bottleneck is security regimes wanting more thorough checks, not the speed at which passports can be scanned. Obviously better economies of scale for direct flights reduces time lost to the hub and spoke model, but that's not a startup opportunity for someone wanting to focus on things other than planes ;-)
There are molecular mechanics/molecular dynamics methods that use only classical physics ("ball and spring" models). That's part of computational chemistry.

To elaborate on your comments, most of computational chemistry does use quantum mechanical models, and there are indeed difficult problems with computational intensity. Basic quantum chemical methods start with a big-O time complexity of O(N^4). The "gold standard" of computational chemistry, CCSD(T), is O(N^7). It is the worst-scaling method that still sees routine use.

https://en.wikipedia.org/wiki/Ab_initio_quantum_chemistry_me...

An "exact" [1] approach to electronic structure calculations, full configuration interaction, scales as O(N!) -- yes, factorial. Not surprisingly, the size of systems tractable via FCI has not grown much in 30 years even as computers have grown much faster.

There is indeed a lot of work applied developing efficient approximations to the "exact" quantum mechanical solution, and to eking out more constant-factor improvements from existing algorithms.

There's also a lot of work on taking electronic structures, available from various methods, and deriving familiar chemical properties from them. Things like NMR spectra, Raman spectra, pKa, melting point, aqueous solubility...

Measuring properties of bulk condensed-phase matter in the lab is easy but it's hard in simulation. Something "basic" like melting point is very hard to derive from ab initio calculations. On the other hand, properties that require expensive equipment to measure, like NMR spectra, are comparatively easy to calculate.

[1] Terms and conditions apply. Consult Helgaker et al. "Molecular Electronic‐Structure Theory" for details.
Parent comment really gives a great overview of the process.

One slight nitpick is that DO-178B or DO-178C are revisions of the standard and the associated criticality is associated with the Design Assurance Level (DAL) from A to E. One would say software is developed to DO-178C DAL B for example.

The DAL is determined before the software is started at the Systems level according to a process described in ARP4754A (Guidelines For Development Of Civil Aircraft and Systems) looking at the system architecture, hazards, and potential mitigations of those hazards, one of which is developing software to a certain DAL.
Long-lived DHCP leases work. There are many examples, try the client IP addresses from the headers of emails that you receive. Geolocation dbs are not magical, but they are often close enough for practical use.
Mostly nuclear, actually. Turns out the average US grid emissions is actually lower than natural gas due to about 37% of the US grid being emissions free.
It was also the tech industry putting money for it too with Benioff.

That of course discounts how the actual tech workers voted. I'd be curious to see polls on that. Anecdotally most tech workers I know supported it.
Not that I recall, but I was surprised at the notable effects overall. Caffeine is so prevalent and people so knee-jerk defensive of it that we don't notice the powerful effects (be they good or bad). Unfortunately, it's been several years and I don't recall any specific reactions other than the sleep and that overall impression.
Great to hear! Thanks! I’m excited for them to pull it off.

Aviation is small fish though. REALLY small fish. This type of aviation even more so. It accounts for only 1-2% of anthropomorphic CO2eq production. Benefits outweigh the bad. I'm not aware of climate scientists actually caring about supersonic travel.

I'm kinda surprised to see this kind of hostility. Same thing happens when nuclear is suggested even though the IPCC HIGHLY advocates its use. It is all about relative impact. Part of the problem with resolving climate change is that even the people who acknowledge it fight among themselves and don't push for both current technologies (which includes nuclear) and research for new technologies (fusion, batteries, and better solar/hydro/wind). We need to just listen to what the experts say, not what you read in some blog post or HN comment.
Penalties are too reactive. Regulation would be more proactive.

A huge corporation will mostly see a fine as a cost of doing business. It won't work when you're looking at negligence, or security, because you can hedge all of your bets on never being found out, or otherwise only being found out so far in the future that the negligence has already paid for itself.

Regulating the storage of sensitive information, same as you have with HIPAA and GDPR, presents a much stronger case for being more careful up front. You're no longer talking about negligence: the expectation for how you handle sensitive info is made clear right from the start, and you can treat egregious violations (like storing passport numbers alongside other account details like a physical address without securing the system) as malicious.
> If you are that strong a believer in the evils of socialism do you avoid Freeways, airports and the internet?

Well you are conflating a few things here, it not black and white. It is funny to see how stating something that seems obvious to me gets me downvoted and categorized as an extremist anti-socialism...

I see some evils in socialism, but probably not the one you believe. For instance claiming that healthcare is free in a socialist country is one of the most evil aspect of it. My main grief is that people treats it as something that they can waste and don't need to be careful about. Same for "free" universities: student thinking it is "free" don't have much pressure to actually take the most of it and be careful about their choice (let's do a first year of sociology studies after high school because I don't know what I really want to do, and then I can still do a first year of psychology studies, and I'll figure later what I'll do with all this...).

On the other hand, after growing up in France and now living in the US, I learnt that this is all not free and I consider this very previous for the French society. I won't advocate against these welfare benefits, on the opposite I think they should reinforced in many ways however I would like the state of mind of people to change with respect to these "free" benefits, starting by stopping to use the word "free".

As a concrete action, I would send the full healthcare statements to patients, showing how much it costs and how much the taxpayers money is offsetting. I was in the hospital in France multiple times, I have no idea how much it costs, I didn't pay anything as far as I remember, and didn't have a statement.
The same approach can be used for University and other welfare benefit.
Contrary to the myth, general anaesthesia does not in fact fully defeat physiological responses to painful stimulus.

I've watched first hand as the anesthetist has said "whatch the monitor as the surgeon does this bit" and seen the response.
I agree with you, because this is more or less what the US is, and in some ways, was intended to be, and in other ways, not intended to be.

If you split the government along Foreign and Domestic policy, the Federal government represents more foreign policy matters with the Senate serving as the outlet for the States to have a modicum of say, and the States generally handle more local and domestic policy matters, except where Congress has reserved power.

The Founding Fathers knew what they were doing, and while what we have is a compromise, there was clearly vision behind the drafting of the constitution, more vision than 99% of armchair historians can muster. In order to scale democracy beyond the level of a city-State and have it survive, they instituted some Anti-Democratic institutions. The Senate is one of these institutions.

Most of those who would like to revise the Constituon lose sight of the fact that democracy does not scale well without some judicious compromises. The very nature of the Constitution and Federalism is counter to democracy. The Senate is counter to democracy. The Supreme Court is counter to democracy. The Presidency is counter to democracy.

If you asked me, I would say we could do better, but we’re not going to do better by cutting down the pillars of society and seeing what we can build from the rubble. The States are as integral to the United States as the Federal Government is to the States.
At their core, they are distinct only regarding when data is copied from kernel to user space. Readiness based copies when the application does the read() after being notified of "readiness", completion based copies (or DMAs directly from disk controller and maps into user space) before the application is notified of completion. The former is easier to use (no buffer ownership headaches), the latter is faster. Though there may be buffer management headaches in the kernel with readiness - what to do about ready reads the aren't collected? (Probably just throw them away if uncollected at the next AIO poll...)
> Instead it should disable everything by default, let the user turn particular permissions on explicitly

That would be great for power users but it wouldn't work for "the average dumb user" since they would just enable every permission when asked to do so if they don't know what it means and how it could be abused. And power users already have that in Android forks designed for them. (I can't speak for iOS.)

The optimization code was mostly written by an advisor on the project, Wotao Yin, in Java.

He used a custom clustering algorithm, not k-means.

We initially tried assigning clusters to couriers, and letting them complete the assigned orders in any ordering (usually according to deadline), however, we ran into issues when new orders came in (especially rushed delivery orders). We settled on a solution of ordering a courier's assignments in an optimized order to increase chance of finishing all assignments on-time, and then only showing the courier one assignment at a time: the top priority assignment. When we closed down, we had been experimenting with factoring in the number of gallons and of what octane each courier was currently carrying.

We had a special business license with Google Maps API, but still cached the driving time calculations to speed up the algorithm / save money. Anyways, the routing algorithm only have to run every time the orders/couriers state changes (https://github.com/Purple-Services/app-service/blob/e0a4f74c...).

When you are tracking every couriers' location you can playback GPS coords prior to an accident and determine if their average velocity was higher than acceptable. You can also tell if they aren't on-task after receiving an assignment, or if there are two on-duty couriers in the same car! We experimented with RFID tag + Bluetooth connection to courier's app, to track actual amount of gas delivered as seen by a flow meter. And, we had an algorithm for recommending gas stations for couriers to fill up at based up price / distance. In B2B sales, a VIN scanner in the courier app was useful for reporting.

> I think I've also explained why I find the information incredibly useful

You have, and your reasons are likewise reasonable - I just struggle to believe that there are so many people that are similar (but again, there clearly are - my struggle to understand doesn't change the facts). People who bike to work, for example, have lots of reasons to care about the weather...yet I seriously doubt that covers a significant portion of people that create the demand for weather apps.

Women tend to have more varied fashion and layers than men, so they would logically be more impacted by weather, yet there's no shortage of men that want that weather info. I get that they do...but I still have troubles accepting that my normal isn't, you know, _normal_.
Again, not comparable. You're comparing a new, luxury car, with the general death rate of roads.

You'd need to compare the rate of accidents of a Tesla with and without the system engaged, or at least the Tesla compared to other luxury cars.

Which wouldn't even be that relevant, because autopilot features have been available for much longer in other cars.

And that's before you include the fact that autopilot hands over the control to humans, so, again, the numbers aren't comparable.

I understand your desperate need to validate your internal assumptions, but you don't have external data to do so.

From a past life as a biologist looking at photosynthesis, IIRC, at least the photosynthetic systems of algae were optimized for (1) "dynamic range" of sunlight and (2) molecular stability.

(1) Intermittent flecks of light - not guaranteed continuous sunlight in the wild.

(2) every photon captured destabilizes the molecular assembly and some captured energy may be better lost than build up oxidative stress.

Of course, this is from a ten year old memory and may be completely wrong.

Actually, I was trying to address "The Copyleft licenses work around that and make cooperation between of adversaries possible" to show that a more "BSD-like" license like LLVM have many "adversaries" collaborating: researchers, enthusiasts, and otherwise competing companies.

I don’t think their track record shows them caring enough about money that they’d break the law to do it. Sure they’ll happily break civil liberties laws or laws regarding assassinating foreign politicians and the like, but that is because those can’t be solved by simply spending more.
