Sure, but a car isn’t the only thing you could potentially plug into a Supercharger. (That’s why I said “the device on the other end” rather than “the vehicle on the other end.”)

Maybe you just want to charge the gigantic custom-built battery bank you use for accessories power in your RV! Or maybe one that’s just a hacked Tesla Powerwall or five. (That’d be the “white-hat” use-case.)

Or perhaps a portable (towable) hydrogen generator, to fill bottles for hydrogen-powered cars. Still an “adapter”, technically, though doing it at the substation-level rather than the near-power-generation HVDC level is probably horribly inefficient and wasteful.

Or perhaps a mobile Bitcoin mining rig consisting of server racks installed in a air-conditioned shipping container on the back of a semi-truck…

Or the lighting and sound for a pop-up roadside rave event!

They're kids that don't know any better and these schools seem almost fraudulent by not being upfront about those career prospects.

It would be good to teach a class in high schools about degrees, careers and salaries so that they aren't just guessing based on feel.
Thank HN: Magnesium and Morning Anxiety
Several weeks ago, I saw a post on HN about mental health and challenges around productivity, coding, etc. Someone commented that their morning anxiety went away after starting to take magnesium.

Morning anxiety is something I've dealt with on and off for a while and I decided to give this a shot.

In short: it's been fantastic.

Just wanted to thank the community. I'm now about 3x as productive in the mornings as I was a few months ago.
You pain went away because yoga relieved you from the stress.
If you’ve got that kind of money to burn on sending your kids there for funsies, is it even “being taken advantage of”?
A school may offer 6-8 PHD openings a year in a department, but have 3-4 times as many students enter the Master's degree program knowing most of them will never get into the PHD program.
> Concepts correctly detect when someone passes to them things that don't implement required functionality

Unfortunately C++ Concepts check syntax even though as you'd expect the intention of the feature is to reflect semantics there is deliberately no way to capture that.

So e.g. Rust has traits PartialEq and Eq reflecting things that claim to be partial or full equivalence relations. There's no syntactic difference, a Rust type can't syntactically be impossible to check for equivalence with some values and not others but e.g. Rust's f32 implements PartialEq not Eq due to NaNs whereas u16 has both since integers all exhibit equivalence.

But in C++ there's just std::equality_comparable and it matches both integers and floats even though NaNs aren't in fact comparable because the float type syntactically has the == operator.

So this means in C++ concepts matching means your program compiles but it might blow up at runtime thanks to a difference in functionality rather than syntax.

To C++ programmers this is positioned as yet further responsibility on their shoulders. They must check that the data they're using actually models the concept that was required, it's not anybody else's job and if they get it wrong the program blows up.
Sorry, I mean no offense. Where I live I have met many yoga practitioners who have peculiar ideas about physiology. They do not represent yoga as a whole, or its traditional practice.

>Considering how low-risk buying pot was before legalization, it boggles the mind why anyone thought there would be a huge growth in consumption, especially when the legal product is priced so much higher that it might as well still be illegal.

I have no idea how much consumption has changed. But for a casual/occasional user seeking out a dealer seems like a fairly high bar. And even if legal prices are higher, again for a casual user, the total incremental amount seems pretty trivial.

Gen Z teens get a crash course in pitfalls of US jobs market
I've had a similar experience in Covid with muscle tightness. It's unbelievable how much our bodies compensate.

It started with a muscle injury to my upper back. Well to heal it, unbeknownst to my conscious awareness, almost an entire half of my body tightened to allow that one area to heal. Like you said it's as if whole sections of my muscles were numb as well, and only after repeated stretching did I "activate" those dormant areas.

And it took being in a very calm and relaxed state (not trivial to do with tightness and/or pain) to "sense" these areas and being stretching them out. Turns out I had to find stretches for all the way down to my big toe to the top of my head and everything in between.

The lessons of body to mind are overflowing suffice to say.
I wouldn't be so sure that the next 12 months will be too much different.

You're citing that looking at earnings from different fields as the place the "market" doesn't belong. If the market has no place in labor compensation, the where does the market belong?
If you're really going to do it, look into Georgia Tech's online MS in CS. The program is 100% online and is under $10k for all classes.
Agreed. I still think there is a distinction, even if only in principle and mostly psychological, between what a company does with my files on their server, and what they do with my files on my device.

Even if the outcome is theoretically the same, the means are different and it feels different.
Huh, so it wasn’t just me who was confused when I tried to use pandas. I found pretty much anything non-trivial to be difficult at best and impossible at worst. (IIRC I needed to sum rows grouped by time period or something like that.) Then again, I haven’t used pandas much at all.

(I’ve heard tell that R is worse, but I wouldn’t have any opinion on that since I’ve never used the language.)
Exactly. My point was this group is very willingly exploiting themselves.
"Lies, Damned Lies, and Vaccine Statistics"

https://drrollergator.substack.com/p/damned-lies-and-vaccine...
So Ford builds two F-150s with serial number 1234. One has internal_db_id 1 and the other has internal_db_id 2. I buy an F-150 with serial number 1234 and immediately smash it into a tree. Total loss.

You buy the other F-150 sn 1234. You take your truck in for service. They refuse to service salvage title vehicles under warranty. You explain you don’t have a salvage title. They blame “the system”. Your insurance company fares no better.

Or, Ford could put a unique constraint on serial number and catch the problem in the factory.

It’s not clear to me how the internal_db_id did anything except propagate an error until it was way too late to fix.

The entire point of properly modeling data is to codify and enforce the “rules”.

> Nature's law are facts. Design your database to rely on facts, not man's laws as much as possible.

Exactly. Natural keys can, along with normalization and constraints, stop you from picking up the ball and walking into the goal. In other words, natural keys define the nature of your system.
Sorry my metaphor wasn’t good enough.
> it also doesn't imply "you can marry whoever you want".

Per my understanding, parents, or their proxies (matchmakers, astrologers, interested close family and friends) source the prospects that their children consider. Which means those potential matches have parental "pre-approval", with things like education, career, and family background already taken into account. From that pre-vetted list, "you can marry whoever you want" is mostly true, from what I've been told. Unless some major red flag comes up during the family meet-and-greet.

It's possible my sample is limited to people from upper-class backgrounds.
It helps to widen your stance. This brings your knees and thighs outwards to make room for your stomach.

As for being back heavy, squat shoes are commonly used in weightlifting and they have an incline built into them. If you don't want to buy squat shoes you can always put a block of wood or something that's about an inch or so under the back of your foot to give you an incline. This helps you get deeper.
It's definitely different in the sense that the required automation, solar panel, and reusable rocket technology for bringing those dreams into reality are no longer science-fiction but a mixture of both current and near term technologies. The vastly expanded knowledge of the solar system since the 70's also means we can actually make informed estimates of economic value of the planets and asteroids out there.

For me it's now a non-brainer that we will be an interplanetary civilisation before the end of this century - even if realistically the overwhelming majority of humanity will still likely live in or around Earth for at least another millennium - barring some major mass extinction level natural or artificial cataclysm (note that even fairly pessimistic projections for climate change do not meet this criteria).

If you are pursuing a Masters degree, I don't think you get the protection defined by being a "kid".
I’d care more about the misnaming if it was frameworks versus anything else, but it’s not. It’s frameworks vs frameworks. You could call it X and say all the code examples are members of X and I’d find the article just as valuable.

I think this is Grade A software engineering content. Here’s a thing you do sometimes, here’s seven other ways to do it with names, code examples, trade offs and real world examples. It’s great for learning because when you come across this problem in the future you have all your tools laid out for you. I also found it personally helpful because I’m visiting Python framework interface options right now. This saved me a bunch of work.
This is fairly common when the data involved are relatively small. It's much faster and a much better user experience to query the server once for a couple of hundred items and allow the user to view it with different criteria than it is to do a round trip to the server every time the user wants to change or refine the selected data.

What's your objection to it?
I haven't found any editor that makes handling of split panes as streamlined as Emacs, and that's because while having the tabs tied to a single document is a sensible metaphor, it's just way faster to have two or three panes whose contents you can switch from an autocompleted list of buffers. No clicking around, no squinting your eyes at the little tab titles, no dragging and dropping the tabs to switch them from pane with awkward snapping in and out.

(buffers can be files, configurations panels, terminals, applications, whatever really)

But editor ergonomics are always trumped by tool support, and Emacs' can be good, but it's never reliable in supporting environments that aren't Lisp and academic stuff like R and LaTeX.
Copenhagen Hypnosis Murders
In many cases it’s disingenuous to argue that everyone will be in the same place as a medical student?

I know someone who spent similar amounts on a UX masters degree, and almost decade later was only finally hitting 100k/yr - in the SF Bay Area. Which cost of living/free cash flow perspective is probably even worse than your $60k/yr med student.
This post was flagged. I just vouched for it. I read the whole thing. As far as I can tell, it is accurate.

There is not a single comment pointing out any error or misinformation or lie or damned lie.

The likelihood that any consulate bothers itself to tell some uni student to shut up is extremely low.
> Regulations that disqualify programs with high debt and low earnings from receiving federal aid would force universities to reappraise master’s degrees that frequently leave graduates in dire straits.

I think this is reasonable. My non-STEM Master's program was tuition free, because my field isn't particularly lucrative, but it is considered important enough to merit large numbers of scholarships. The only programs that would be hurt are those that are neither in the interest of the student nor society at large.
Well, a good time to say Bravo to their regulator then.

Imagine if the regulator, and the state airline was ran by people half of whom shared the same surname, and it happened, say, in USA.
This Museum Is (Not) Obsolete
Yes, this!

I am by no means an expert, but I have spent time and experience enough with chronic pain to state that this rather one dimensional. Meaning their group although big was narrow in scope. For example, no chronic head pain?
We have been working on a VR body mapping app(https://www.hatsumivr.com/), I'm the art lead on it. And you quickly find that there is an ocean if different experiences out there, and thats probably the biggest obstacle to helping people with chronic pain. Its is often treated (at the policy level) as one condition with a select few options for treatment. Studies with conclusion like this reinforce a reductionism in medical spaces and leave the people that don't fit into their pidgin holes out in the cold, alone, and in pain.
In fairness, some of that was due to maximum password length, a silliness I have yet to see totally disappear, but was much more endemic back then.
While it's not wrong that there are other options for storing wealth, crypto is the first one that is easily transferable across borders and thus far has shown to be resilient at not being controllable by government.

Multiple attempts have been made over a decade to control crypto. The most recent China banning miners for example showed that crypto just adapts and overcomes.

This of course is scary for the people who used to have complete control over money, and even more so for countries that can no longer control their citizens by seizing their assets.
I don’t quite understand why this is big news. Is it really a surprise that having a very large amount of money enables you to do things other people can’t do?
Petals, Flowers and Circle Packings
Squatting with weights is one of the most beneficial exercises you can do that targets a lot of muscle mass, is trainable with incremental weight addition and gives a large range of motion for the muscle groups involved. If you're going to be doing only one weightlifting exercise in the gym, make it a squat.
Right, that seems to be the consensus read.

I guess my point is that even PoW systems won't be entirely unaffected (albeit not quite to the extent that PoS systems are), since validators are crucial to the integrity of the blockchain.

To attempt to extend the electric car ban analogy: this feels like adding onerous/infeasible reporting requirements to pipeline operators (PoW validators) and power plants (PoS stakers), neither of whom know anything about the end customer refueling at the pump / charger station, but not the oil refineries (PoW miners).

And yes, the reporting requirements would also be in place for the electric utility (PoS validators), which still doesn't know anything about the charger station's customers.
> Even without the prices being uncapped, there's no guarantee that a gTLD will stick around.

Actually, there is a guarantee that a gTLD will stick around. ICANN correctly determined that this would be ruinous to the health of the Internet as a whole if entire TLD's worth of domains could simply disappear, hence they set up procedures to guard against it, including a required daily data escrow deposit from all TLD operators that can be used to spin up the TLD by another registry operator if the worst catastrophe were to happen (which, it should be pointed out, has never happened). For more info see:

The only TLDs that have ever ceased operation entirely, like .xperia in the linked articles, are closed brand TLDs that were never used for anything, were never available for external registration, and that the company in question (Sony here) simply got tired of paying the annual fees on given their lack of use of it. These TLD discontinuations don't threaten anything.
No, I didn't agree to automatic updates by turning it on. In fact, I don't have automatic updates turned on.

What happened is that I updated based on what Apple claimed the update did, but they were lying. Contract law would seem to be on my side in such a case.
Academia is not elastic, many universities have limited spots for the in-demand classes like CS. For medicine, residencies are the limiting factor. Academia in general refuses to scale and be responsive to market demands.
Because it's the land that drives value in the Bay Area.

I suppose you can use some weighted combination of lot and house, but I haven't seen common and simple valuation metrics there.
Slightly, but still not competitive against renewables. When the spot price of power goes negative, renewables aren’t as impacted as coal plants (that are still burning a fuel every minute that must be paid for, while also paying someone to take the power they’re generating). Renewables can curtail, coal must stay running.

Bug in Lynx's SSL certificate validation – leaks password in clear text via SNI
I took the bait, I'm ashamed. I try to keep an open mind, so I read some of it.

The thrust of the article is that vaccines work well at preventing infection, but that if you do get infected, it is _possible_ that you might die at a higher rate. _Possible_ comes from a big spread in the standard deviation of P(death|infected & vaccinated). I didn't check his calculations, I took his numbers at face value and just looked at the charts.

The author uses big standard errors to make claims about what could or could not be true, because the standard errors straddle both favorable and unfavorable statistics for the vaccine.

However when the standard errors are too small for this dubious reasoning, they come out in favor of the vaccine.

The author appears to me to be using motivating reasoning to push an agenda.

Edit: sorry I am not completely right, because I wrote this comment before thoroughly reading the whole article. Sometimes his standard errors come out against the vaccine, and for all I know his math could be right. But I don't want to check the math because I have limited time and I don't care if my death rate goes up given conditions {x, y, z.}

I care if getting the vaccine makes me less likely to get sick and die, which it does, because if you look at all the tables and charts that's exactly what it shows.
I was meaning it in terms of purchasable supply. Nothing is stopping anyone from building a new city center in the middle of Montana, such that it has plenty of buildable supply.

That is, you can say that dense cities are more effecient, but that only matters if you can build another one. Otherwise, there are more affordable homes further from existing city center then there are in them. And that is going to be hard to change.

You seem to be pointing that existing cities should double down on their density. I'm claiming if that was such a clear path to success, it would be done in new places.

I do suspect there is a mix of both.
I second this. Been using it for years, easy and reliable.
I think its kind of like when in Clojure, you only activate validation on the boundaries of your program in production, and disable the validation in the internals of the program.

Because a factory would still test its input, or the input would have been tested by the supplier.
>I don't think the comment you replied to was saying it's only bad because Canadian. They were stating every time they hear about food being destroyed it pisses them off.

But if you're against food waste, shouldn't you be supporting supply management (ie. preventing excess production)?
I believe that lack of habit formation is a big part of at least some ADHD cases. Having your unconscious make something a habit is how you learn to focus, if your unconscious doesn't decide to make things habits and instead just look for new ways and solutions to do stuff you'll have a hard time focusing.

I don't think that lack of habit formation is necessarily a bad thing, making something a habit is good if that something is good, but bad if you learn things that are wrong. Meaning I'd argue that people who are worse at forming habits are likely better at rethinking their beliefs and theories.
This is the list of all currently existing TLDs:

It's just a matter of time until someone can create a "ThisChildPornDoesNotExist" site, then send links to targets to have their lives ruined. I am extremely worried by humans policing the Intertubes, and even more worried by algorithms doing so because they make the perfect excuse to do sloppy checking. See Youtube DMCA related takedowns for multiple examples.
I'm not one for turning up my nose to criticising government's like China's but the reality is that freedom of speech is not an important aspect to Chinese society (including many others) and if one wants to work there, travel there, and not endanger people there as he has done with his girlfriend's family, then one needs to at least consider the consequences for critical speech and whether they're worth bearing.

> There was also no risk to his GF. At worst, the relationship ends - it's not like the CCP is going to go after her (she did ask him to stop).

I'm not sure why you think being so apparently reasonable is also something her government and its supporters care about?
I do think it's very important to be clear what your statistics are saying, and everyone has done a pretty poor job of being clear about that.

But in this case, what people really want and need to know is how well the vaccine is going to prevent them from dying.

They don't care about the difference between "Prevent dying from covid" and "prevent dying from covid once you have covid". The latter simply doesn't matter to them until they have covid, and then it's too late for the vaccine. That statistic is meaningless to the general public.

People only want to know if the vaccine can help them not die. And it absolutely can because it helps prevent getting infected in the first place.

Edit: I just realized the statistic that people want: "How likely are you to die from Covid if exposed to it, vaxed vs unvaxed." Not if you get it. Just if you're exposed to it. And since we don't run tries where we deliberately expose people to viruses, it's going to be a hard number to get.
All up installed cost of solar per kWh is now cheaper than fossil fuel fired power plants but it's only been that way for a couple of years. Power plants are build based on a 30-50 year lifecycle. It's like trying to steer an oil tanker (hah) - we ARE turning, it just takes a while.
