Indeed. The pre-COVID schedule was that all active lines had their last train leave from the end of their line at midnight. The last SF to East Bay would be the SFO train, which would hit Civic Center around 12:30 am.
The Optimality of Upgrade Pricing

Sorry, wasn’t trying to be pedantic… just thought it was an interesting point of trivia.
I'm no expert on the economics of airport shops, but here's my take:

Rent prices for airport shops are high and space is limited. If you reduce your prices to be more reasonable, you are relying on volume to make ends meet. This is challenging because space for inventory is limited and expensive in an airport.

So, most shops in airports either (1) have to charge high prices to make a profit, or (2) aren't actually in the business of making a profit and are instead a marketing tactic for big brands. There's a lot of foot traffic in airports, so the big luxury brands will be willing to spend money on an airport storefront, even if it comes out as a net loss on sales.
I’m nowhere near qualified enough in general relativity to evaluate their claims, but when I see something like this:

“This is aesthetically pleasing, as nature seems to strive for harmony, efficiency and simplicity.”

it makes me think they are not being the most objective evaluators of reality.

Thought-out and creative. They took advantage of the nice glass-view they have in terminals. There is space with outlets where you can get some work (ie: browsing HN) done. I took a photo (this was pre-covid). The other big one (for me, haha) is that they had the smoking lounge very close. So I leave my laptop/bag for some vaping while being able to watch them from inside the smoking area.

Relative imports used to work much more naturally IMHO in python2 but then they broke it in python3 because Guido wanted scripts and modules to always be separate codebases. So, whereas it used to be easy to have a module that could also be run as a script inside a package, this is now very difficult to implement. To the extent that any python2 code that does this, should probably be refactored when being ported to python3.
Yes, but it's getting harder to find at good quality. Amazon says "not available in the US". Try DramaCool.
"Joe's home made solar panels. No panel nor voltage is alike!"
> That's a problem addressed with [public key infrastructure (PKI)]

I don't really agree.

Yes, you want to use PKI. But it doesn't solve the problem of needing to immediately update all your equipment when there's a key leak, and replace or reprogram a huge number of cards. PKI just makes things a bit smoother in general.

My suggestion is pretty simple. Have a few different locations that sign keys, have them all sign each card, and require multiple valid signatures. Exact details up to the implementer, but that way you could have at least one key leak without causing any user hassle.

> And other countries are any better...? Try replacing "Americans" with "people".

Yes, I wouldn't extend it to all people of any nationality, but e.g. London tends to have better escalator behaviour because they're so frequently encountered by large groups of people on subways, and last time I was there, even some stations had signs to encourage the "keep right if standing".

> I've heard horror stories where each member of a team uses it's own subset but practically for many years of dealing with C++ I do not feel I ever had problems when I had to work with other programmers.

I feel the technical lead should be catching these problems during code reviews, and establishing best practices, etc. Also this problem exists in other languages, perhaps elevated slightly in C++, but until rust came along it was 1 of 2 choices you had for certain problems (C being the other obvs.). Speaking of rust I thing the jury is still out on whether it can catch up with C++ in terms of popularity.
Stop using decisions factors that seem to benefit one race over another.
From a quick read of the manpage, I don't think it's possible either, unless you mess with EXEC or create multiple listeners to a single address.

Anyway, the Linux kernel does have a builtin loadbalancer in the form of shared sockets that you can socat outside of the machine. But I wouldn't call that a socat loadbalancer.

Perhaps voters should consider another party in the city. If your leaders are not making the right decisions, why don’t you vote for different leaders? Being completely married to a single party seems to lead to these types of outcomes. No matter how bad the politicians do, no one will vote against them because they are married to the party, for better or worse.
IIUC the authors are saying that if we associate the metric with the four-potential via an outer product, they get a picture coherent with the current understanding of how electromagnetism "works" in GR under certain circumstances.

I can somewhat see how to interpret the mathematics in free space. But what about when there are massive bodies in the picture? They will result in a non-flat metric... does that imply they create their own electromagnetism?
Equality Slipped Away
I actually think power grids are adapting faster than vehical type is changing. You still see large trends towards large trucks(speaking for North America). But Fords E150 fits right into that along with having 220v and replacing a generator, they will do well with contractors and construction crews, I think.

Right now a lot of old coal infrastructure is going offline and being replaced with solar/wind. So the makeup of that electricity is trending towards green. Even natural gas is better than coal. But it’s a huge amount of generation to change too.
Are you the UncleMeat from Netslaves?
In the western world a lot more will die, hopefully most of them because they weren't vaccinated. In the non-western world a lot more will die because they couldn't get the shots. This also means that there is always a risk of a new covid variant that does not care about the vaccine.

I don't see new lockdowns unless we get a variant that can reliably breakthrough the vaccines. The reason is simple: lockdowns were barely accepted before, they won't be when it is percived to be peoples on fault.

On the downside: we are now seeing the effects of global warming, and the hurricane season has only barely started. No this doesn't mean we will do anything about it, but it does mean that it could get ugly, especially if the US gets hit with several large hurricanes.

Of course all of this assumes China won't do anything momentarily stupid, like trying to take Taiwan. Then everything is up in the air.
JFK and EWR don't have direct connections to public transit, but instead offer a mediocre people mover to a nearby train station. LGA only has a bus.
The PerCapitaEmission thing is something we can curb without returning to to stone age, given today's technology.

We have two major technologies that allow for producing useful energy without producing much or any greenhouse gases: nuclear and solar. Wind and hydro are also on the table, but are more constrained by the environment.

We also have reasonably well developing technologies for meat-like protein production from plants (see e.g. the "impossible burger") and lab-grown meat. They are currently a bit expensive, but it's mostly the matter of investment.

Sadly, all that massive construction requires steel and concrete, which emit CO2 during production. Here comes carbon sequestration: we absolutely have technologies to quickly grow massive amounts of trees, cut them, and put them to use either as a long-term construction material, or just burn the hydrogen out of them to produce energy, and bury the carbon in the empty coal mines, playing back the carboniferous epoch process.

This all does not require colossal amounts of novel science or sci-fi technological breakthroughs. It does require though that petrol cars and trucks get steadily replaced with electric, coal mining all but stopped (we need carbon for steel production), oil pumping severely limited (we still need jet fuel until we can synthesize enough), coal-fired plants demolished or turned into nuclear plants. It requires massive construction of solar, wind, and nuclear (gasp!) electric generation, and massive construction of battery capacity to make solar practical for base load. It requires shutting off most of beef production, and replacing it with fish and shrimp farming, lab-grown meat, and plant-based pseudo-meat; red meat should become a luxury like salmon roe or caviar.

The obvious problem is that most people would totally not cooperate if they'd have to quickly and radically change their way of life, their idea of what prosperity looks like (bye grilling beef over coals!), and their jobs (coal industry? oil industry? bad luck!). Can this be overcome? Either most of the Earth's population, across national, political, and religious divisions would willingly make such a change, or an planet-scale dictatorship would emerge and consistently and efficiently pursue the goals of climate change reversal, while not severely affecting productivity. I see both scenarios utterly unrealistic :(

So, buy that realty next to a major northern river 1000ft above sea level. In a century it will have the best climate Earth can offer.
Nowadays, corporate and govt surveillance is pervasive. Consequences cannot be "dealt with" after the fact, and deletion is no longer an option. Mistakes are a part of your "permanent record," (with a nod to Jane's Addiction).

A gauge field is tensor-valued; what's wrong with that?

Although it does seems strange for other reasons. Primarily because it seems very unlikely that everyone else who developed this field wouldn't have considered the possibility and then discarded it.

Bullying may not have a gender but in the aggregate it's different between boys and girls. Note the word "aggregate". There are invariably anecdotes the contradict the aggregate view but the point is that it's not an absolute, just an aggregate.

There's lots of research on this topic.

You see the ripples of this well into adulthood. You see it as the expectations placed on girls and women where they're held to a higher standard than boys and men are. And who are the agents of that? Other girls and women.

I'm not female but all of my experience has been that no one tears women down more than other women and that female bullying is generally much, much worse than male bullying (at least until male bullying graduates into violence including sexual violence).

Why? Because it seems to be much more multi-faceted. Instead of being primarily physical dominance and signaling, it encompasses social alienation and psychological torment.

Japanese escalator etiquette is impeccable. I used to take a four-story escalator at rush hour every morning and even though I’d walk past about 200 meters of people in line, the right side was always free for walkers.

It’s gotten slightly worse in the past decade or so—I won’t speculate about the reasons—but people doing it wrong are very much still rare enough to be the unexpected annoyance.
There’s a paper with equations linked at the bottom. I suspect it sounds like gibberish because its describing a mathematical proof with common language. The paper assumes you have a lot of knowledge as well.

ⓐ accept and knowledge both problems and find reasonable compromises while keeping the larger/global picture in mind.

ⓒ Ramp up Oil production as much as possible to sell as much Oil as possible, covertly use money and influence to make people dependent on Oil but in the country and to the press say that Climate Change needs to be stopped and Oil usage needs to degree and make your country less dependent on Oil usage (so that it has no problem when it runs out and so that you can sell more).

ⓒ Some where in between? But I assumed the hypothesis is about countries which produce Oil in a economical relevant amount, so I'm not sure there is a "unremarkable average".

As far as I can tell Norway tries to go with ⓐ but not perfectly 100% commitment, but then expected a perfect type ⓐ approach is IMHO unrealistic. For example as far as I can tell their Arctic(1) expeditions are more about being able to keep their Oil output around the current level if necessary then about ramping it up.

A country which could be saied to go with type ⓒ is Saudi Arabia I think, but I'm have vastly to little knowledge about it to make that judgement.

(1): One note about Arctic Oil mining. There is nothing which makes Arctic Oil mining inherently more climate damaging then non-Artic Oil mining. The reason many see it as a no-go is more related to environmental concerns (which are not the same as climate concerns!). Through there are also arguments about reducing the amount of Oil which can be blasted in our atmosphere by blacklisting Arctic Oil. Either way while there are many reasons to complain about it I also can think about reasons why it might make sense and why I maybe might have done such decision. (Mainly related to increasing geopolitical tensions, increasing influence of China, and the China US conflict.)

Whoogle is a Google anonymizer and stripper-of-chaff, searx is a content aggregator on top of that same concept.

this is visibly happening with retail and commercial properties, but people here swear up and down it absolutely is not happening with residential properties.

This doesn't make any sense. The value of a lease on these properties vastly outweighs any property tax deduction.

Where do you have to pay for Wi-Fi? I hit about 15 different American airports back in 2019 and didn't run into this.
I’ll trade all of that just for some free luggage carts. Charging for them seems to specifically be an American thing and it isn’t doing our country any good image-wise.

I’m guessing the reason isn’t just profit, it’s also to pay for the infrastructure to collect the carts and shuttle them through the terminals and back to their corral. Okay, fine, but tell me how this suppose to feel when a passenger actually decides to pay the fee? If they’re arriving to the airport by taxi, they need to scuttle all their bags over to the corral, pay by credit card, slide out the cart, and then load it. And if someone’s driven them to the airport their car is now idling at the entrance even longer, causing other arrivals to wait.

You’d think this would become a lawsuit at some point, or at the very least airlines would realize they could make even more profit with additional luggage fees.

The dangerous question is: Is it turning a profit (or at least breaking even?); or being supported by the government. Because the Asia economy flights are "dirt cheap".
LaGuardia in NYC requires transferring to a bus for the final connection from the subway to the airport. It’s infuriatingly difficult to get right even after doing the route many times. I’d often call a Lyft/Uber at 10x the price of the subway+bus because the public transit route is that annoying to deal with.
They’re choosing suburbs for value, not cost. There are plenty of apartments available in cities at rents lower than the average suburban mortgage payment.

If we want revitalized cities where people want to live, we don’t just need low cost housing, we need high value housing. The middle class didn’t leave cities on cost alone and they’re not going to move back to cities on cost alone.
This is interesting and if the experimental evidence confirms this hypothesis, it bodes well for our future. A universe where we can interact with spacetime via engineering is one that allows for a lot of creative freedom.

It was when the A3000 came out that Macs started looking more attractive to me. Originally, it was like "4096 colors, cool!" but once high resolution screens became more common, flickering interlace mode and 16 colors was underwhelming.

16 bit color made HAM irrelevant and was more exciting than pre-emptive multitasking and graphic acceleration.

BeOS was almost acquired by Apple to replace the Mac OS, but it wasn't, and it makes you wonder how history would have been different.

I think bad code gives raise to more dependencies in general and so circular dependencies.

But the truth is sometimes it has happened to me and the only solution I found was creating an small module with maybe one or two functions which is not exactly ideal.
if FTL travel were possible we probably wouldn't exist. Whoever came first would probably colonize the Universe and sterilize it of competition

FTL doesn't necessarily mean infinite/instant travel. Also the scenario you propose could be part of the Great Filter, and we just haven't been culled yet. Or FTL civilizations tend to get so large they fracture & turn to in-fighting or encounter other resource bottlenecks that limit exponential expansion.

Or C is the law and going FTL spawns a cosmic traffic cop like the meatball head things in Rick & Morty.

Or FTL is simply impossible, but perhaps not constant and various factors impact the local C
Really good timeline presentation. I think that Napster/peer-to-peer circa 1995 deserves to be added.
It felt like things advanced faster back then. The Amiga was a huge leap over other 16-bit platforms when it was released. Time doesn't stand still, and hardware wise the platform barely evolved between 1985 and 1994. AGA was the only major change to the platform, other than faster processors, which every other platform was also getting. Example: An Amiga in 1994 had the same sound chip ("Paula") as one released in 1985.

The slow, incremental improvements weren't enough to keep up with x86 and SVGA. Commodore really dropped the ball. If the 1200/4000 was released in 1990 instead of late '92 it might've been a different story. The 1200's performance was hobbled by lack of fast memory out of the box and a previous generation processor (68020, which as 5+ years old at the time.)

Early versions of the OS were also primitive and unstable. That didn't change until 2.0 which wasn't generally available until late 1990.
Because you're not a parent, here's a tip: kids are tougher than you give them credit for and they're tougher than they understand. Your responsibility as a parent is to figure out how to toughen them up without crushing their self-esteem.

Instagram is not an essential part of any of this. If the worst thing your kid can say about you when they hit adulthood is "daddy didn't let me on Instagram," then you did a phenomenal job.
I would agree, although not completely – but will I also claim that this falls under discussing, studying, funding, and doing more science %D

Ah, and, it didn’t occur to me to make the distinction, but I was thinking of personal and direct funding of science. As something each of us might arguably do. It’s interesting to consider it because we arrive at the same question: What to fund?

There’s a safer way to run self-signed software on macOS, for anyone that prefers not to do the master disable. First, try to run the program.

Then, you can run the program. You need to do this only once per program.

> When cities grew before airports and so the underground is already full of subways and infrastructure, it can be prohibitively expensive to build a new fast tunnel to downtown.

If the city is already full of subways, the job should be easier, not harder - now you only have to tunnel your way to the closest existing station and then extend the line.

Germany once had a flourishing industry producing solar panels. Domestic demand was high, supply followed, driven by high subsidies to home-owners producing solar electricity. For a few years all was fine, until Chinese manufacturers provided lower-priced panels. Instead of protecting domestic manufacturing through import duties (which would have been justified because Chinese were dumping below cost at times), the government stood by and did nothing.

Now politicians are crying about the long way panels travel over from China and that we no longer have domestic manufacturing...
Very great anthropological argument that "it's human nature to be selfish and self-serving" is a load of nonsense.
