It depends what the change consists of. In blockchain, we tend to talk about "hard forks" vs "soft forks" when it comes to protocol changes.

In a hard fork[0], blocks produced by the newer version will not be accepted as valid by the older version (e.g. increase of block sizes, changes in rewards or additions of new opcodes). This will result in a split of the blockchain, where old and new nodes operate on two concurrent diverging chains. You can think of it as a git fork. A hard fork essentially requires all nodes to upgrade.

Hard forks are generally activated by first adding the functionality without activating it but signalling for compatibility, only actually enabling the protocol change once a subset of nodes have signalled support.

In a soft fork[1], blocks produced by the older version can be deemed invalid by the newer version - otherwise the two are compatible. This means that users don't strictly need to upgrade to participate, only miners do.

So TL;DR, if BTC Core developers released a hard fork, it would only go into effect once it reached majority support among miners. In practice, users and other stakeholders (most notably exchanges) also have an important practical voice in which chain is deemed the canonical one, in case of a split.

The worst code I've ever seen in my life are Spark scripts written in Scala.

Scala is so complicated that people use only a fraction of its features, usually the simpler ones.

It takes a real commitment to become a prolific Scala programmer.

> Dynamically typed languages are even worse.

I don't comment on personal taste, everybody has their own.

Which means that someone, somewhere is going to get paid to create a dummy electrical load. We've never (as far as I can tell) seen "grid stability" payments for using electricity before.

Kinda, sorta. The whole conceit behind wholesale energy markets is balancing congestion on the system by changing the locational marginal prices (LMPs). If you have a very congested line, a generator with a negative shift factor (their generation will reduce flow on the line relative to the constraint) will see high prices to turn up, while generators on the other side with positive shift factors (will put more flow on the line and exacerbate congestion), will see low-to-negative prices to turn off.

There is a lot of development in these markets (in terms of energy, capacity, and ancillary services) with respect to energy storage resources, and co-located (solar+storage) facilities. If you want to know more about that, reading up on FERC Order 841[1], and the various RTO/ISO implementations to date is a good place to start.

My grand grandfather was saying that he only bathed once, when he was baptised.

He lived for 107 years, a happy and mindfulness life. He ate meat once per year, at easter and he drunk one bottle of koniak per week, along with one packet of cigarettes per day.

But the most important thing, i believe, was that he had two ears, anything that went into one ear was going out of the other. He never bothered about anything, he lived 3 wars, buried 5 children but he never got sad or sorry.

But, who knows, maybe it was the distance from the shower. And, by the way, he didn't smell bad.

This. I have been saying exactly the same thing since the start of iPhone Vs Android. ( Remember there used to be a War between the two? )

Apple is trying to create its ideal computer, which is actually an Appliance. iPhone was that, with added custom and App ability on top.

Google ( And Microsoft ) was trying to shrink the PC into Phone form factor.

Arguably the two meet somewhere in the middle. But they differs in fundamental principles and values. To be point I believe if there were no profits and vested interest in App Store, Apple will be happy to shut it down and only offers default apps.

I also agree the payment terms and how the handle developers were extremely poor. Did I mention Discovery and Search on App Store sucks?

Another benefit of Religion is community. I recall back when we went to Church we had tons of people who took the time to reach out when things weren't going well.

That's easily the difference between being an isolated island of a person, miserable thinking the world is against you. Or being a bit down, and getting a hand up.

This is a fair way to go about it. Really, my point is that you're likely to use the cloud.

And if you're running a small/solo shop, you really need to learn the basics of that cloud vendor before rolling out on the cloud platform. I see too many people roll things out on AWS without any knowledge of the platform whatsoever.
1. I have been lucky, but I’m also a 2nd generation immigrant. I remember how many things my parents had to deny themselves (and me) growing up. Of course this mileage only takes you so far, but on many incomes, there’s real power here. The fact that it’s painful to deny yourself these things is the point. Most bad financial things happen to people who won’t tolerate that pain, so they get locked in marginal situations with little room to take risks or have anything go wrong. Eventually, something always goes wrong. This is the only way to protect yourself. It doesn’t mean it doesn’t hurt.

2. This is the exact point. Each of us have to judge the consequences of failure for each decision. If you only have a couple hundred dollars left after expenses, risk aversion is the right call—-and falls well within the real of managing your risk.
People with positions of power are regularly found to take bribes that wouldn't even be a 1/10th of their normal paycheck. Power tripping is a recognized phenomenon, and greed makes people do irrational things sometimes.
Yes, there's not much that can destroy a legend easier than meeting them in person.

But it in this case, the legend was a rather nice person. Getting this aspect of his personality destroyed would be a shame.
True, these founders are dead. But Ford's family still owns a huge share of the company and has never renounced the patriarch. It's not just testing fraud with Volkwagen, that's just a symptom. Check out, for example, recent reports of their use of forced Uighur labor, for example.

These were only stark examples, but you're not really saying, management of any major auto company has a good role on climate change (well, except Musk) or profiteering from government subsidies, or labor relations (in the USA consider the move to low-wage anti-union jurisdictions by all of them).

I'm not a fan of Musk's social or political views, much less his huckstering. But no way differentiate Musk from leadership of other auto companies on any vector other than the level of attention to Musk's flaws, other than, perhaps he's invited media attention by being so public about it.
Only read the article, which could be very different from the actual study, the Forbes article is referring to people already hospitalized so we are talking about a pretty low bar of health already (low but probably common, make note of that reality), and of those people they are "getting" Vitamin D, which kind of suggests after they are hospitalized.

This is new data then, because earlier studies were saying that Vitamin D supplements weren't improving circumstances, which would reinforce your perspective that people with inadequate Vitamin D levels had other issues.

This article doesn't specify what "getting" Vitamin D means, maybe the study does.

Let me know!
Corporate environment is rarely honest even if everybody knows what given thing means. You can literally compose dictionary to normal speech at some point.

It's remarkably hard to actually "own" anything on the internet. The act of paying for something or not does not dictate what's your property - ASNs are leased, IPs are leased, domains are leased, connections are leased and you'll need to either pay or use someone else's to host something on the internet. The closest you could come is legacy IPv4 space and not rely on traditional infrastructure such as DNS.

Most registrars have decent trademark policies but again it's the internet. Just because you have a trademark in your country doesn't mean someone else doesn't elsewhere or that the registrar is going to care 5 years from now when the ToS change on renewal.

If you want to be securely verifiable on the internet you're better off being searchable and signing your content. The hard part is finding people that care enough to verify who you are in a decentralized manner for that to matter though.

Even if something is continuous, that doesn’t imply that all borders within it are arbitrary. And even among borders that are somewhat arbitrary, not all of them are equally arbitrary. Whether a metal is iron or lead is a kind of question that aligns more with the workings of the universe than the question of whether the current month is September or October.

The goal of cleaving reality at the joints is not entirely hopeless.

In a bimodal distribution, there is a point which is a local minimum for the probability density which lies between two local maxima of probability density.

As to whether an infinite amount of classical information is needed to perfectly describe the behavior of physical objects, I am agnostic. As to whether a bounded-in-size physical object can be used to store an unbounded amount of classical information, I’m fairly confident that this is not possible (as a thing that happens to be true of the universe, not something required by logic alone).

(I am not arguing that “whether a sample is entirely lead” is a perfectly discrete question, as, I hear that it is thought that on extremely extremely long time scales that quantum tunneling may cause collections of lighter-than-iron elements to combine and form iron, and so even in a sample of “pure” [some element lighter than iron], maybe there might basically immediately be some minuscule component of the wave function in the “these atoms combined into some heavier element” direction? I’m not sure. I don’t know whether that would decohere or whatever immediately and therefore with high probability go back to a state of purely the one element? Idk.
What I am claiming is that even if there is a continuous path connecting states we would call element A with those we would call element Z, it is nonetheless natural and _Correct_ to make a distinction between different elements, and these distinctions are more natural and less arbitrary than other distinctions we might make.)
If you look at the other comments on this thread, you'll quickly see why people like myself write comments clearly explaining what studies actually show. There is nothing wrong with understanding that the knowledge we have today is limited to a set of possible states - further study, such as the link, help collapse those states. Honestly, it makes the narrative more compelling too as showing direct action is easier than disproving all unseen movers.

If a train is the best solution for a USA community, by all means, make it happen! However, trains are optimal in the USA in far fewer scenarios than either automobiles, buses, or airplanes.
Doing a calculation chain with RPN does take a bit of practice to do correctly and efficiently. It's probably a little easier on the 42 because the display shows the Y register. That said I've been using RPN since I got an HP-55 in college (retiring my TI after a year--calculator prices were dropping fast at the time).
as a highly multi-modal angeleno, i love the idea of a small, cheap electric car.

however, you make the very common mistake of focusing on speed as (inverse) proxy for safety, because that's what's been beaten into our heads by the confluence of politics, media complicity, and industrial lobby.

the biggest issue wrt car accidents is distracted driving. speed is only a contributor to severity, not the cause of accidents. reduce distracted driving and reduce accidents. reducing speed only reduces severity while increasing susceptibility to distraction. plus, you can reduce speed in populous areas (where overall danger is highest) through traffic calming measures like narrowing lanes and lining streets with trees (which heightens alertness too).

but the measures to reduce distraction are contrary to convenience, comfort and expression of "personal brand", which is why hardly anyone wants to tackle that real problem and instead blindly piling on the speed bandwagon as a palliative rather than a solution.
In the northern states, you burn long before you get enough vitamin D around the winter solstice. Assuming the sky is even clear.

Signal theory is deeply interesting based on your line of thinking here. I’ve been postulating similar things. The universe gives a lot of potential for things to communicate. In the end what is recognized as signal and or information is a matter of imagination and consistency given the plethora of potentially unlimited signals available.
This is why it shouldn't be required either way. People who want to work from home should be able to work from home. People who would prefer to come into the office should be able to do so. It disappoints me to read comments here about people proclaiming absolutes in either direction. To be clear - I'm an advocate for full-WFH: I am fortunate enough to have a space for working and a space for other. ... but I recognize that some people have different situations at home.

As a childless person with a roommate, the current WFH situation has been not ideal.

I live in an apartment complex that normally features amenities and is located in a neighborhood with lots of shops, cafes, bars, gyms, etc. All of the third places are currently closed or under very heavy restrictions (e.g. in Seattle you can only dine indoors with members of your household), so now I'm stuck in a two-bedroom apartment. I can still go for walks but it's not quite the same.

There's also the issue of everybody else. On paper, I have gig internet. In practice, I don't think the fiber here was designed for everyone to be simultaneously working from home. And especially with kids staying at home instead of using up their energy at school or at the playground, apartment noise has become more significant.

Work from home would probably be nicer under less strenuous circumstances. Working from home or a coffee shop of your own volition is one thing, working from home because you have to is another. I'm onboarding to a new team and personally I've found it difficult to get the quick 30-second validation I need to see if I'm setting things up right or have the right assumptions, because it very easily snowballs into setting up formal meetings.

I agree; life is easy and a little bit boring for more and more people in the 21st century, unless they specifically choose to do risky things. I think that is a very good thing. I also agree that the media tends to report on bad things and downplays progress. However, I think what is underreported is not the 21st century inventions you mention, which get media coverage, but rather deep long-term global health improvements that began in the 20th century and have been continuing since then: metrics like infant mortality, food security, life expectancy, the eradication of polio. A great source for this is: https://ourworldindata.org/

As for specific 21st century technologies, let’s take those you mention one by one:

> Unprecedented access to information;

Yes. Although this was the growth of the internet and the web, both late-20th century technologies.

> - Instant high fidelity communication and work/business;

Same as the first point.

> - Private and ever-cheaper space flight;

To do basically 20th-century things like putting satellites into orbit... but cheaper! I hope we do something genuinely new this century like going to Mars - but that’s some way off.

> - True automation (it's only the beginning of the 21st, I bet on automation hitting hard mid century);

You’ll need to be more specific but sounds like this isn’t here yet? I agree automation has been improving but again, it’s a long-term trend.

> - AR/VR (which will likely become the escape of choice for much of the world later this century);

Sure, although sounds like this is more about future promise than what we have now, which is a fun but niche entertainment.

> - Renewable energy that most can afford (it's already realistic for everyone to be self-sufficient);

This is good but... again 20th-century tech becoming better and cheaper.

> - Viable artificial/grown organs (for use in medicine and food production);

Promising research but still a way off from becoming a routine medical treatment.

So... I think all of these things are great but, as I mentioned in another reply, they just don’t have the world-historical impact of key 20th century tech like the Haber-Bosch Process, or antibiotics, or powered flight, or effective birth control. I think we are in a phase where we’re mostly improving what we already have (which is great!). Maybe a novel 21st-century technology will come along with that kind of impact, but I don’t think it’s here yet.

It took me a really long time to learn this. You have to be secure enough in yourself that your mind can even contemplate the idea of taking the initiative to say something negative about yourself in front of others. On top of that, you need to have the courage to actually do it.

And it's so easy to let it slide. You'd hardly be the first. But it really is better to do it. Contrary to what insecurity tells you, reasonable (and non-adversarial) people will respect you more.

> I think a big reason why the python 2 to python 3 transition was so painful was a lack of static typing.

And I'll add compilation vs interpretation to this. I have, on a couple of occasions, had to update Java or C# code from one version to a much newer version. This meant that deprecated features were often used (more an issue with the Java cases). Thanks to actually compiling the code and the static typing, most of the things I needed to update/change were apparent from the start. This didn't mean they were good "modern" versions of the program, but they were functional and operational and could interact with newer Java and C# code bases properly with only a week or two of effort.

The same was true when a library was changed in a breaking way (at the interface level). Of course, you still need tests when semantics of the library change (like it returns the same type, but with different meanings), but that's usually well-documented.
Never write someone or something off without solid evidence.
It’s honestly embarrassing to hear all the worthless arguments against types.

The cognitive load of a dynamically typed (or unityped, or “untyped” or whatever) language is massive, yet the common argument is that types «increase» the cognitive load??? How does offloading a large majority of the trivial reasoning of a program over to a type system, ”INCREASE” the cognitive load???

It’s just so endlessly easier to program with types
Blasphemy laws suck
This is an extremely reductive. Temperature or gravity are not composed of people, who have the ability to make change within the system they comprise.
I've been working remotely for 6 years now, and 5 of those was at Pivotal, a culture famous for pairing. I love it, and I have turned down offers that cannot guarantee me a similar situation post COVID.

We used Zoom since ~2015 regularly, and Hangouts before that, and given that the company had many offices around the world, and the majority of teams were distributed (largely optimizing for the same timezones), being home office-bound was no different that being on another office. We constantly experimented with the latest tools and practices to be more productive at a distance. For example, some pairs were connected on video all day, in addition to keyboard/screen. It wasn't easy for everyone, but ended up achieving the goals.

Post COVID, my current company is in the process of re-imagining office work, more towards intense collaboration spaces. Most of the work can still be done remotely, getting together for specific activities every once in a while. I really believe this model could represent the future for this type of work in tech.

If the company culture is such that remote employees are not second class citizens and HR has set rules to back that up, anything is possible.
