Proof of Authority. What matters is the reputation of the source. You can have varying degrees of trustworthiness based on an source's reputation, which is built up on the chain.

For example, Craig Wright has faced a lot of backlash for claiming to be Satoshi Nakamoto. There's been no way for him to be proven wrong. Recently, someone signed a transaction with an address that hadn't moved Bitcoin since 2009 (implying it was an early adopter or contributor) and they called out Wright's lie (he had claimed to own that block).

So Wright lost credibility. That's what we need. We need the ability to develop reputation on the blockchain and a way to punish that reputation economically for posting invalid data.

EDIT (I'm out of HN replies):
Reputation can be established based on a staking transaction. You create a smart contract for say, independent journalist Tim Pool. He signs it and stakes some amount and publicly declares that address to be his. He posts all his videos with a signature embedded that can be validated against that contract. The hardware itself (with algos signed by chip manufacturer) could also sign the video. An open source app could also sign. If you've got 3 signatures on a video HW, SW, and individual (associated with smart contract address) and a public blockchain timestamp, you've got a high degree of trustworthiness in that footage.

Kubernetes and containers used for the new B-21 Stealth Bomber
Looking at just gas stations, they could spin it into a benefit since the customer will be required to stay at the station for a significant amount of time (~30 mins?) to charge instead of a few minutes.

You lure them in with the electricity then push all your high-margin crap on them like drinks and snacks. It would massively increase foot traffic to quick-service restaurants, cafes and other activities on or near the premises as well.

People will go to stations less, but they will spend more time there. Current EV utilization of paid, away-from-home chargers shouldn't be expected in future when EV owners can't just rent a ICE vehicle for any trip greater than ~400km roundtrip.

US is on the brink of two major things.

1. a civil war: lots of guns lying around n a demagogue in the white house. n trump like a rat, he's been biting n blowing air on the wound. come nov, he can easily say the elections were rigged, if in the small chance event he loses to sleepy Joe i.e Biden. he's supporters will buy it, as they already bought about mail in voter fraud. n his repeated calls for violence against minorities etc. people frustrated by the economy n elites etc

2. a major depression: this is already in play, as unemployment numbers had been propped up. n the fragility of the US economy i.e dependent on excessive credit n consumption.

so it's catch 22: which one is gonna happen first.
True. Maybe just converting to radians and then nobody will question your eventual math for correctness.

My understanding is that medieval Rabbis (notably the Maimonides) explicitly discuss cannabis consumption and its psychological effects. The plant also gets some discussion in the Talmud but in the context of its use in fabric and as candle wick. It is speculated that certain plants mentioned in the Torah refer to cannabis but these strike me as a little tenuous. At the very least the use of cannabis as an intoxicant does not seem to be explicitly mentioned in the Torah. So I wonder, if it was commonly used for that purpose in the ancient middle east, why little to no mention of this? I mean, there is a mountain of detail about all the other minutiae of ancient custom.
I'd like to interrupt all the sanctimonious blathering in this thread to note that Cloudflare domain registration terms and conditions are almost a verbatim copy of Google's, and includes the same unilateral cancellation clause for phishing.

Cloudflare: "Cloudflare and Registry Operator may deny, cancel, suspend, transfer, redirect or modify the Registrar Services or a Registration, or place any domain name(s) on lock, hold or similar status, as either deems necessary, in the unlimited and sole discretion of either Cloudflare ... for distributing malware, abusively operating botnets, phishing, piracy, trademark or copyright infringement, fraudulent or deceptive practices, counterfeiting or otherwise engaging in activity contrary to applicable law."

> To me, the economy looks insanely resilient in a global pandemic.

We’re still in the early days of this pandemic, as it usually takes many months for the upfront shocks to fully process through the economy. Numerous reports detail a potential collapse of the commercial real estate market, the government is signaling that it is going to hand out any more stimulus money, and health experts are warning about a second wave. Economists aren’t ruling out 40% unemployment down the road, which puts us firmly in depression territory.

I have no idea where you live, but I live in Austin, TX, a fairly affluent city, and the changes to the city have been dramatic and very visible. So much retail is still closed, and many thousands are out of work with little opportunity to renter the workforce and likely without future stimulus.

Just look at the George Floyd protests, there’s an inherent economic component to American racism and Covid provided a lot of fuel that the senseless killing of Floyd ignited. Those events did not occur in a vacuum, which is partially why we’re seeing unrest that we haven’t witnessed in 60 years.

Not to mention that millions never recovered from the last major crisis while politicians and big business pretended like everything was back to normal after the big market rallies.
> Just use Gmail and spend the time on something more worthwhile. The die-hards who still, in 2020, complain about HTML email are just wrong and absurd. Contrary to what they say, HTML email is very useful for discussing code: e.g. the ability to send well-presented syntax-highlighted code fragments for discussion is helpful, not a hindrance.

> Really, I feel the same way about projects that insist on doing development by email.

Wait. HTML email is useful for reviewing code, but you don't like when code reviews are done over email? Which is it?

I see no reason for HTML email to exist, but I've stopped trying to fight that.

Emacs is far superior to any email client for editing text. And so is VI for that matter. I've used a setup to send emails from Emacs (but not receive/view them). For that, Mutt and something like Notmuch are far more useful.

Even today, even though I mostly use Outlook (because management, I have no excuse if I miss a meeting because my client didn't properly parse the Outlook invite), I still find it useful to compose long emails in Emacs and then just paste them on the editor.

I do agree that a full email setup on Emacs can be a waste of time for most people.
If I can continue your analogy (though I admit it's a little confusing) - if a gang member is caught breaking the law and we have another law preventing prosecution, let's fix that bug.

Structural issues which create gangs need to be addressed, and it's true that convicting the gang members might detract from the need for those structural reform, but enforcing laws is still a part of the incentive system we have to encourage people to not break the law.

We should fix structural issues, but that doesn't mean we need to leave clear bugs in tact to increase pressure on fixing those issues.

Trying to make Scala better for "simple" projects is definitely a focus of this book. You are right that traditionally the fixed overhead of learning Scala made it only worth it for huge and complex projects, but this book introduces it in a way that's easy to learn and easy to get started with, making it feasible to use for tiny projects 1 line of code and above.

In particular, none of the projects in this book take more than ~2 pages of text (~90 lines). You implement a programming language in <90 lines, a real-time network file synchronizer in <90 lines, a websocket chat website in <90 lines, a massively-parallel web crawler in <90 lines. These are 90 line complete applications, not "90 lines changed in a sea of boilerplate" or some other nonsense like that!

The goal of all this is to make a case that yes, you can use Scala for small projects! But you'll have to read the book to see for yourself if you find it convincing :)
Gas stations are not completely obsolete, they have other uses, mini mart, restroom, tire/window maintenance, potentially electric. Some portion of them should continue to be useful.
My own focus is more on science education representations. And on how badly they describe the represented physical systems. Emphasizing that this seems as much a science community failure, as an education community fail.

Consider an illustration of the solar system in some introductory astronomy content. Let say, that not atypically, it misrepresents sizes, positions, orientations, lighting, and Sun color. Thus creating and reinforcing misconceptions known to be a problem in K-12, in undergrad, and even on into astronomy graduate school. In contrast, consider a line representing an Earth-Mars transfer orbit. It seems unlikely that students will say think there's a material long pole there, and worry about it hitting satellites and cities. Students and teachers are both clear on the aphysicality of the line, but not of the Sun color. Hmm, though using a minimum-energy line to represent an energy landscape is a source of misconceptions.

Similarly, common representation of atoms and molecules are known to be causatively associated with the stew of misconceptions that pervade students and teachers of chemistry. Ribbons, perhaps not so much. Hmm, though also similarly, they're often used without indication of regional flexibility, and so perhaps contribute to the underappreciation of configuration landscapes, of the importance of tuned floppiness. Perhaps.

Consider a currently implausible goal, of science education which accessibly describes the physical world, and conveys a transferable understanding of it. Arguably its content would look much more like scientific visualizations than content does at present. But being for education, it faces additional constraints, challenges and tradeoffs, distinct from those of professional scientific visualization. Creating such would require a collaboration of both deep scientific and educational expertise. For which very little incentive exists at present.

I'm trying to come up with an XR-compatible visual representation of electron density, that is physically correct, accessible, and bears in mind patterns of misconceptions in chemistry education. That task should probably be more than one random software dev's lockdown hobby hack. But as far as I know, that's were we're at. The related NSF-funded work I've seen... doing this bit well wasn't their focus. Same with XR ed tech side. Same with chem ed apps. And scientific visualization programs. And chem ed research. There may well be something nice out there, but I've not yet seen it. And big ed side... I was chatting with a leading textbook publisher, which onboards content creators with the indoctrination that their liberal arts background, and complete unfamiliarity with science and tech, is not a problem... because there's "a scientist" on call. Deriving electron density, with current nice python libraries, and GPUs, has surely gotten vastly easier than it was with old fortran messes, but still... it seems something more is needed here. Some societal staffing seems missing. No?
This is an interesting study in HN ranking penalties. Two hours in, there are 25 points and we haven't sniffed the front page. Currently ranked #126.

You are correct that BlackRock has an incentive to maximize their AUM to maximize their revenue.

A critical distinction though is that the Fed isn't buying BlackRock's bonds. They are buying bonds that are represented in BlackRock's exchange traded funds that are meant to mirror prices of real bonds.

You're not wrong that it's a sweet set up. It's better to be in BlackRock's place. It is better to be buying coronovirus bonds for the government rather than selling them to the government. The latter implies your company is under severe cash flow pressure.

You shouldn't be distrustful of BlackRock because they maximize their revenue when they maximize their AUM. If they maximize their AUM, that probably means that your income is maximized as well.
I don't find it too bad most of the time. If the pipeline isn't working you can cut it off at any juncture and watch standard out to see whats going on.

You can even redirect some half processed data to a file so you don't have to re-run the first half of the pipe over and over while you work out what's going wrong in the tail end.
This seems inspired by r/askreddit, but without the low impact anonymity that makes that sub work.
>Seems like policy written by petrol car drivers

It sounds like policy written by the convenience stores (I assume some sort of convenience store owners special interest group or association exists in Germany). Their business model is they sell gas at approximately break even and make all their $$ on the store. They stand to lose big as things move electric. If they can get out in front of it and be the place where people expect chargers (as opposed to expecting to charge at the grocery store or work) to be then the stand to gain a lot of business. No one store or chain wants to be the first mover though so you get legislation instead.
Honestly people don't want to go to a gas station and wait and watch people fill up while their car charges, they'll park somewhere where they can get out, sit in a cafe, do some shopping, go to work, or go to sleep - in short people use chargers in a different way than they use gas pumps.

I think there is a place for gas stations with chargers .... along the interstate .... but not in cities

Isn't that just "maybe"?
As an American with an EV this seems out of touch. I've lived downtown and in suburbs and gas stations have never been nearby.

Street parking needs EV charging and gas stations maybe need fast charging but not normal level 2 charging.

You can have a financial system without a stock market. It would be constituted with public banks or various kinds of credit unions.

Not really. A financial system that only consisted of debt and not equity would not be able to support anything like our current economy. We would all be much poorer for it. Loans are simply not suitable for a huge variety of financial risks.
I fell in love with Clojure and fell out of it. It is a great language. Lisps have this inherent elegance to them especially in data transformation pipelines.

That said I found its performance still a bit on the wanting side particularly if you avoid type hints. For many tasks the performance is probably acceptable but the backend work I tend to do makes the abstract style get in the way of trying to figure out performance issues.

Also I'm coming around to the imperative style more and more. Sometimes a for loop is all that's needed and makes for a more understandable code than all those hipster maps and folds.
The incremental cost of running the transmitter is low enough to justify keeping it on all night. There are always people who can't sleep or are working graveyard shift and they will tune in.

I think Scala adoption is doing great.

A lot of the initial hype around things like Akka and Pure Functional Programming has died down since the frothy excitement of 2015-2016, but honestly I think a lot of that hype was oversold and many of these things never quite lived up to their original excitement.

Right now, the level of hype has fallen back to where the real value is: a solid language allowing flexible styles to suite a wide range of use cases, as concise and convenient as any scripting language, with excellent performance, tooling, and static checking to prevent defects.

With this book, I'm obviously hoping to drive adoption and prospects up, and I'm doing so by trying to sell the value prop above rather than the value props that were (over-)hyped in the 2015-2016 era

You can imagine a successful financial system without a stock market if you don't know much about financial systems, in the same way that you can imagine a jet flying without wings if you don't know much about aerodynamics.

I believe that the rise of importance of finance has been a net good for humanity, but I know that's an unpopular opinion and I've seen good arguments that it's a net harm. But I don't think you can make a reasonable argument that we could have a modern world anything like the current one without stock markets. Banks and credit unions don't, can't and shouldn't provide the kind of funding that equity markets do.
Reading this [0] Wikipedia article, it sounds like "Weapon of Mass Destruction" is not a super well-defined term to begin with:

"The most widely used definition of "weapons of mass destruction" is that of nuclear, biological, or chemical weapons (NBC) although there is no treaty or customary international law that contains an authoritative definition. Instead, international law has been used with respect to the specific categories of weapons within WMD, and not to WMD as a whole."

However, there is one definition given in the Wikipedia article that seems to be sufficiently precise:

"""

(1) Any explosive, incendiary, poison gas, bomb, grenade, or rocket having a propellant charge of more than four ounces [113 g], missile having an explosive or incendiary charge of more than one-quarter ounce [7 g], or mine or device similar to the above.

(2) Poison gas.

(3) Any weapon involving a disease organism.

(4) Any weapon that is designed to release radiation at a level dangerous to human life.

"""

I definitely agree with your overall point that defining AFADS as a WMD will require careful navigation of the blurriness surrounding the category. On the other hand, it seems like that second definition is already in the territory of choosing arbitrary cutoffs (ie 113 grams).

An alternative perhaps is to focus on handling the "autonomous" part, rather than the "swarm" part, as the USMA article suggests. The definition here can be more precise/less arbitrary I think: a weapon that can at any time be overridden by an operator is not fully autonomous. However, if its regular operation includes a period where there is no operator in the position to override it (eg the drone(s) keep doing their thing while the operator is away from the controls), it would then count as fully autonomous. Having some authentication that the operator is at the controls at all times, available to override and legally responsible for the behavior of the drone(s) is the key to this approach I think.
