The problem with fuel cell vehicles is they still need batteries. Not as big of a battery, but they still a battery of some kind because the fuel cell can't deliver burstable power the way a battery can. So the FCV is really the worst of all possible worlds - all the complexity of a fuel cell, plus all the rare earth needs of a BEV.

I also can't believe that the production and distribution network for hydrogen could be anywhere near as efficient as direct distribution of electrons. This whole idea seems like a nation-scale Rube Goldberg machine.

> Sure, let's have a tariff on goods made in a country, that scales proportionately to the per-capita CO2 emissions in it.

Again the obsession over per capita data, which totally obscure the fact that the US per capita emissions have been in a constant decline over the last 20 years while China's have been growing at an uncontrolled pace.

Which behavior should we incentivize, unrestrained pollution because they "aren't THE worst yet" or hard work curbing emissions?
Progressives in the US have been demonized since Vietnam. The War on Drugs is on record as an attempt to associate enemies of the Republican party with something that law enforcement could be used as a weapon against. The peaceful skinhead movement was hijacked in an attempt to associate them with neonazis.

In the 90s the middle east was radicalized from years of being occupied by western military forces. 9/11 was, in their words, intended to be a wakeup call to the American people. It was terrorism in every sense of the word: intended to strike fear into American citizens in the same way that they already lived in fear of US forces, with the goal of destabilizing their enemy.

Two decades of right wing propaganda later and it's clear they've succeeded in radicalizing the US right. Progressives never stopped protesting attempts to violate personal freedoms, but conservatives consistently wield their fear as an excuse to persecute anyone who doesn't fit their definition of being an American. Now fear is at an all time high, which means right wing militias are stronger than ever.

Studies show that while both liberals and conservatives are susceptible to misinformation, there is far far more misinformation that appeals to conservatives in circulation, and as a result, the impact of misinformation on conservatives is greater: https://advances.sciencemag.org/content/7/23/eabf1234.full

Jan 6th was a precursor to what's to come. It's only a matter of time before we see another 9/11, but this time it will be carried out by our own citizens. Right wingers, who live in constant fear fed to them by their media and internet bubbles, will want their "enemies" to feel the same fear.

Who are their enemies? Basically everyone: https://www.thetrumparchive.com/insights/insults

So either we control the stoking of fear (which is very questionable for a govt to do) or we monitor these militias as probable terrorist cells (also questionable).

I don't think there's any way we survive this century without another world war. The internet is too important and influential for it to not spark a huge conflict amongst homo sapiens who haven't yet evolved to know how to wield it.

They partner with police. The revenue play is charging governments access to a feed of events happening just in their jurisdiction (with some cleaning up/grouping of similar reports).

Citizen gets the police to pay them for access, then gets the police to advertise the app to them as an alternative to calling non emergency dispatch. In turn more people down Citizen and Citizen can probably monetize that.

In LA they even have Citizen branded patrol vehicles rather than community service officers as a pilot program. So rather than having like an unarmed (and normally unsworn) employee of LAPD in a Prius with a little orange light on the top, you get a private contractor in a citizen branded vehicle doing the patrol.

The big question is if Citizen gets into E911 systems, which have a lot more liability than non emergency type things. Is Citizen going to make a play to become the standard way of contacting 911 via text based communication at some point and attempt to generate revenue via running that infrastructure.

Think this through; is Somalia poor because their government doesn't give poor people enough money to consume?

No. Somalia is poor because they produce very little right now (for a variety of reasons). If you look at countries that have recently increased their standard of living on a massive scale, such as China, they have done so not because they consumed their way there. A huge amount of investment into productivity was undertaken.
It's not red herring at all if you have a certain moral take on the world. There are long-lived, well justified moral positions that would say that it makes no difference if 99% of the population is entirely comfortable, the fact that 1% makes (say) 10x what the other 99% make is just indefensible.

Everyone on this board seems to think that the next auto fuel source has to be one-size fits all, like with gas.

which democratic president was censored on Twitter?

You're assuming all pages are equal. Censoring the Daily Wire is not the same as censoring the local stop climate change page, for example (not that DW has been censored). Your study counts all pages equally, but frankly, it shouldn't.

Censoring the POTUS is more dire than censoring some small leftist organization, because POTUS is more influential.

Perhaps weight the censorings by # followers or a similar metric. We know that right wing alternate media is more popular than left wing, so my hypothesis would be a weighting would reveale something more dire.

First of all, that's not true. You can test it: create an empty file and name it keygen.exe. It won't get deleted.

The code inside the file has some similarly to one of the hundreds of thousands of malware used to train Defender, and there's a false positive.

None of that matters, though, because you can just not use it if it causes problems for you.

I worked for a while in a "normie" office (not a tech company) and I was blown away by the amount of junk food people ate. In some areas each row of desks had piles of junk food at the ends and there would constantly be cake for people's birthdays etc.

Other places I've seen offer a "fully stocked" kitchen (read, junk food) as a perk. Why the hell would I want a constant supply of crap I can easily afford to buy but don't because it's unhealthy? I consider myself to have pretty decent self control, but some people don't and it's like offering crack to an addict. I don't even agree with vending machines at work.
> Even the newest Tesla Model S Plaid on the fastest supercharger takes 52 minutes to go from 5% to 95%

The thing is, you don't actually do that in practice. Go and actually listen to the insideev podcast. The Tesla will tell you where to stop for how long. Typically on a road-trip you actually make a few more stops and only charge from 5% to 60%.

Unless you are a really extreme road tripper, peeing and getting a quick snake is more then enough. The guys on insideev actually do a huge amount of road tripping (with all kinds of cars) and they prefer EV to ICE for almost all trips. And in most cases the charging doesn't hold you up much at all.

Also guess what, if you drive uphill with cargo in extreme temperatures you also use more gas and your car doesn't get its normal mileage.

With an EV you actually get much of that energy back when going down the mountain on the other side.

Also, this is probably less then 0.1% of all miles driven. So it really doesn't work as an argument and doesn't apply to 95% of the people. And for another 3% it likely doesn't apply for more then 1-2 a year.

Nobody is saying that EV are literally perfect for every single case ever. But as a practical matter, they are simply better for the majority of people already.
The arguments for facial recognition and license plate readers are much more complex. In the case of a gunfire detector, you're specifically looking for (supposed) activity that indicates the most serious possible crime might have occurred seconds ago.

Facial recognition and license plate readers are used to automatically track individual humans wherever they go so that they can be quickly arrested if they're on a to-arrest list. I'm not entirely sure how I feel about that, even if it's all taking place in public, open areas, but it's a totally different category from just knowing when and where a gun may have been fired. It's real-time crime detection vs. alleged criminal detection.
Charging infrastructure buildout will no doubt influence new EV sales, but the timeline of a transition to EVs on the road (as opposed to the dealer's lot) is largely a function of the secondary (used) market. The secondary market, I think, will transition slowly because as EV take-up increases, the price of gasoline is likely to fall.

Several manufacturers have already announced waypoints for their transition to EV. Audi is targeting 2026 for a full phase-out of ICE [0]. Among its light-duty products, GM aims to sell only ZEVs by 2035 [1]. Ford passenger vehicles sold in Europe will all be electric by 2030 [2]. I could list more, but the message is clear; it is an impending transition and automakers will likely use certain marques as a beachhead for going fully EV while keeping the ICE vehicles compartmentalized in other marques. A headline of "Jaguar plans to be all electric by 2025" is more compelling than "Tata Group plans to sell more electric cars by 2025," even though both headlines describe the same story. Similarly, automakers that have struggled for the past decade or two (eg, the American ones) seem to be taking this opportunity to redefine their role in the market as first-movers.

Price and perceived cost of ownership (net maintenance and repairs) are a major part of consumer choices, too. As an extreme example, look at places like Ecuador where new vehicles are so heavily taxed that it's common to see forty-year-old cars on the road. The old cars hold value because few can afford the new ones. If EVs are not price competitive, perhaps there won't be so many customers willing to pay a premium for them.

As far as I am aware [3], the current version of the infrastructure bill as negotiated does indeed include a hefty sum for EV charging stations. I for one believe this is an impactful decision given the long-known chicken and egg problem that EVs face. Ultimately, I think we are slowly reaching the point where the incentive for private businesses to install chargers is becoming clear. Tesla for one is opening its charging infrastructure to other brands [4].

"THINK about DIFFERENT brands"

Hospitals suing patients to get them to pay medical bills is something that could only happen in America.
Maybe have a look at borgbackup docs to use the same terminology, otherwise it might get confusing.

When you create a backup ARCHIVE in a borg REPOSITORY, the archive contains all input files you gave to borg.

Each archive has a name and usually the name is something like machinename-setname-date-time.

You can create such backups rather often (that is cheap, due to deduplication), but you do not want to keep tons of archives long term (some borg commands take O(archive count) time).

Thus, one runs borg prune to "thin out" archives and only keep some following some prune policy, like keeping 60 daily, 12 monthly, 10 yearly or so.

It is important to use --prefix if one creates multiple different archive sequences in the same repo, e.g. if you create pc-home-date-time as well as pc-system-date-time - then you need to run prune with --prefix=pc-home- and another prune with --prefix=pc-system- .

Usually, archives are not modified after their creation (the only way to do that is to carefully use borg recreate command).

May I infer from this statement that you agree with me that Julia draws mostly from an academic user base? In that case, I do not see how your counterexample invalidates what I said. Perhaps some constructs from Julia end up in "real world production languages" but what I said is that the development experience in Julia is subpar and it shows when one is trying to develop larger codebases where software engineering practices become more important.

The blockchain is just a platform. You have to build projects on top of the platform. Asking what does it do doesn't make any sense. It's like asking what does a piece of paper do.

The real question to ask is not what does it do but whether the trade offs of using decentralised tokenised platform for building real world apps is useful or scalable. The answers to which are still being discovered.
Along these lines, what's fun is to look at property sale records.

A shocking number of large properties in the US have not been sold in multiple generations. A lot of old money "just" owns land and extracts rents for that ownership. Many of those people have jobs, so they do not necessarily look like the idle rich. But they have a somewhat easier time because they receive some portion of the ongoing value of land (this could be rents, timber sales, mining rights, etc.).

> But those things are anti-car. They come at the cost of travel speed or congestion as a result of fewer lanes. They're thereby something you have to fight the masses in order to get, instead of finding a Pareto-optimal solution that can thereby actually be implemented.

At the cost of parking, possibly. At the cost of travel speed, possibly. At the cost of congestion, unlikely.

All of the proposals for bike lanes that I have seen have typically involved the removal of parking or the narrowing of lanes. The former typically happens where there is not enough space to use parked vehicles as a barrier between lanes for motor vehicles and bicycles. The latter is typically intentional, since narrow lanes are a mechanism for traffic calming.

Neither should be classified as anti-car. Bike lanes typically run along roads that are mixed use. They aren't found on side streets since they don't address the safety issues found on side streets. (Side streets may be designated a bike route, but I have never seen a separation of traffic.) They are rarely found on roads since roads are intended to serve high speed traffic travelling long distances. There are usually better solutions for cyclists in that case. The end result is that bike lanes are usually placed along business corridors (e.g. those main drags), where traffic calming benefits all users. Parking is often less of an issue in those cases since those businesses couldn't be sustained by the limited parking available to start with.

Cyclists are not out there battling against cars. It simply doesn't make sense. Many of the places that cars go are undesirable to cyclists. Many of the places that cyclists want to go are better served when accommodations are made for multiple modes of transportation. If you choose to interpret that as anti-car, well, there isn't much I can do about that aside from pointing out that it is not the intent and rarely the outcome.

This is just absurd. "Better" is not a metric.

You may disagree with the metrics for "better", and/or you might disagree with the metrics for "less free", but the core point is that these things are not simple.

A good reason to why you should shut the fuck up
Hey guys.

I've been trying hard to fit in, but it doesn't work.

When AI-generated stuff gets upvoted, you have to reconsider the mechanism. I would argue that posts should be voted along a number-estimate of how the content should be ranked (pondered by the voter's weight if needs be). That way, intricate content can pop out easily, even if only a few souls can grok it. Inversely, a powerful voter can push down wrong, illusive content. Don't tell me it can be gamed, because it just can't. Worse to worst, you authenticate more strictly.

That's only one thing. (and which is going to be downvoted for no reason, of course)

I also wanted to argue about why you should just shut the fuck up. Everyone is grossly licking Steve Jobs's nuts without a second thought about ethics. This is only one data entry. I'm very aware that he is dead. That's just to point out that if you look closely, you can see all over the place that people are not being good people. They are being a bunch of neurotic bitches.

It does sound ironic, and that makes me laugh.

Am I going to be downvoted although my words are pumping good dynamism into the culture? Would you rather see another startup trying to invent you a need which you don't have, because they're too weak to break free from the wage-slavery? Excuse me but I'm on disability, because I'm schizophrenic you see, and so I'm free to do and say as I want.

If you would only shut the fuck up, then I would fight for your freedom.

I think you need to put a yet on the Walton's throwing you in prison. Extreme wealth inequality tends to distort surrounding institutions as all individuals paychecks become beholden to the wealthy individual.

In company towns the boss could absolutely have you thrown in jail if they felt like it. If Carnegie didn't like someone then the Pinkerton's would happily take care of them.

The only reason we haven't seen modern equivalents to the above scenarios is that the information age has increased competition. But if you already don't feel like you could sue any of the Walton's for any reason and win... then just wait for when their wealth is 10x larger.
