Magnetic field != gradient of magnetic field.

Changes in fields induce currents, you can stop your heart or cause seizures with enough currents in the wrong places.

Field from a magnet falls off with the inverse cube of distance... so "I was somewhere near an insanely powerful magnet" isn't really saying much.

In an MRI you're probably more likely to see effects of heating from the excitation RF-- which is multiple kilowatts of UHF for 1.5T magnets, and scales with the field strength.
Somewhat related anecdote: Roughly 20 years ago, I took part in a scientific experiment which aimed to confirm a theory that in blind individuals, parts of the formally vision-related parts of the brain are involved in reading tactile braille. The experiment itself was pretty interesting, since it was conducted in an fMRI machine. Back then, the f in fMRI was sort of the new thing. I was used to a yearly MRI checkup, so this is why I volunteered. It wasnt particularily relaxing, as every session took roughly 3 hours. They tailor-made a helmet from gypsum so that my head wouldnt move at all. My compensation for all of this was clearly not the money (which was too little to remember), but the relaxed chat with the lead brain researcher and the MRI technicians during and after the experiment. At the time, the magnetic field strength of the fMRI I was getting was the highest I ever received. I was used to MRI around 0.5 tesla. During the experiment, I was getting 3 tesla. And I was feeling a strange sort of shiver going down and up my spine. They were experimental imaging people, so I took the opportunity to chat about the fonrtier of healthyness. MRI has this air of "you dont feel it and it cant hurt you". I still believe around 3 tesla can be perceived slightly by your body. I have received higher magnetic field strength in normal medical settings since, and sometimes I can feel that shiver. Anyway, as we were chatting about tesla, the scientist dropped quite casually. "At 11 a mouse is cooking." So much about boundaries. I never asked him if they know because they tried :-)

That you didn’t see this, make me think that some cultures have more use of irony than others. I can imaging that in a potpourri of cultures like the USA irony can often be misunderstood and therefore is less used than in other countries.

I also wish I knew how others in this situation fare. As a Canuck, I want no special treatment for anyone, pro or against, but just the job done correctly, and that means fair, compared to how others are treated / the law.

Although not uninvestable the risk appetite needed to invest in China has now readjusted to a higher threshold. How this will play out out with large investors (private equity, hedge funds etc) is that they will assume a higher "discount rate" in their financial models. Essentially a Chinese investment will need to meet a much higher expected return threshold (IRR - internal rate of return) than previously required.
I'm not certain there is a level of foster care that could provide good outcomes. I think that's a bit of a pipedream. If your argument is instead that a shitty life is better than no life at all, I couldn't really disagree. But I think it's somewhat inhumane to bring a new life into the world knowing it will be suffering.
sqlc doesn't quite work that way (though "sqlx" and other packages do). sqlc generates code at build time that avoids reflect by using database/sql's Rows.Scan() with pointers to fields (see the link above):

var i Author
if err := rows.Scan(&i.ID, &i.Bio, &i.BirthYear); ...

This generated code is exactly what you'd write by hand if you were using database/sql directly.

As earthboundkid points out, database/sql itself may use reflection under the hood to convert the individual fields (though the common cases are done without reflect, using ordinary type switches: https://github.com/golang/go/blob/d62866ef793872779c9011161e...).

I was a contractor at cap1 (of credit card fame) 1990s. Learned some good and not so good stuff about how CC corps think about their clients. Anyway on tech/biz side:

- most cc stuff run on cobol code

- cobol code has three buckets: cash advance, purchases, other. Hard to change

- cap1 tried to rewrite that system in c++ for distributed unix to ditch cobol and mainframes. They wanted N buckets so they could hook up with N vendors and have N incentives to build biz

- big failure ala chaos report also from 1990s. Also org dysfunction. The mainframe guys fought it much like in today's world when you have old guard fight for onprem or colo DC when somebody wants a cloud provider

- cobol won then (and I haven't been back in CC since) but not for tech reasons. In truth in abs terms cobol isn't hurt or help. There's bigger adjacent fish to consider first

It’s mind boggling to me how much HN refuses to pay (only for company licensing) for the innovation that is Docker, and would rather find alternatives to the tooling around it.

Usually I’ve seen arguments the other way around - X will do a good job /because/ it’s their core offering.
Well, the Moon is some 1+ light second from Earth, with average orbital radius of 384,400 km. L2 in Sun-Earth system is roughly 1.5 millions kilometers. That roughly makes four times difference.

Fusion is on my plate too. I've got a design that I really need to test, an I've finally got the funds to begin construction.

My method uses much lower magnetic fields that could be provided by permanent magnets, but should allow containment times on the order of weeks for small quantities of D-D fuel.

Your job does not speak to your intelligence.

Janitors can be smart too. Maybe this is all because movies like Good Will Hunting aren't made anymore.

One of the easiest way to increase global sales of our SaaS products is to sell our product in the local currency of our market. But there's another mechanism to increase the sales even further, That's pricing our product according to the purchasing power of the market.

Those who sell physical products have been doing this from the beginning of the global trade, But SaaS product developers often tend to ignore the value in pricing the products according to the purchasing power. After all, A product price should be what the market is willing to pay!

Besides increasing the sales, I think it's the right thing to do.

I wanted to price my products according to the Purchasing Power Parity but the existing calculators are all outdated or non-functional. So I had to build one myself and I'm sharing it with you all folks today.

As for the development, I've been a vanilla JS guy and wanted to experiment with the reactive libraries for a while. Recent selection of Vue.js by Wikimedia Foundation piqued my interest in it and so this project was perfect opportunity to explore Vue.js.

Let me know if the figures from the PPP calculator reflects the reality in your country.
in fact they make a lot of money from institutional investors https://www.theblockcrypto.com/post/116855/inside-coinbases-..., so def not an underdog.
Good point. I had assumed Rows.Scan() would have just used type switches for efficiency -- it looks like it does for common cases (https://github.com/golang/go/blob/d62866ef793872779c9011161e...) but then falls back to reflect. I wonder why it doesn't just do all of that with type switches? Maybe there are just too many cases and it ends up slower than reflect for the rest of the cases.

Scanner.Scan() is actually just called via a type assertion, though I guess implementations of Scan() might use reflection.
This is why challenger banks are a thing, and why the big banks are starting challenger-like new banks.

Anyone who has actually read even the first few pages of the so called "gold standard" study cited knows it was useless and inapplicable to any meaningful public health practice. But the narrative MUST NOT BE deviated from. I don't think we as a modern civilization will recover for a hundred years from the way in which institutions like nature have debased themselves with political pandering.
Two of those six dishwashers were Boschs. The Miele is far better at cleaning. (Though, admittedly, I don't think either Bosch was top-of-the-line. Their best models might be much better than their midrange.)

And if a Miele dishwasher actually cost $4000, I'd probably have a Bosch today.

That may be true, we'll know when there's a controlled study. But it wasn't politicised as much when other countries were doing it.

People decided that doctors have their best interests in mind and they would do everything they can to save them.

Also the media in other countries were not running disingenuous stories calling them fish tank cleaners and horse dewormers. Looks like people have a huge distrust of American media/CDC and that's their own doing.

The only way you can justify this point of view is by using the most extreme case where you have implied violence in a public medium.

99.9% of people's facebook posts don't look anything like that. You're essentially using the argument of "if you have nothing to hide, why should you be against this"
I know it's relevant because it's the politics that are setting the rules right now, but political agreement isn't really the crux of the discussion for me. It's about minimizing suffering and the ethics of controlling someone else's body.

That said, I don't think there will be political agreement because it's not 100% about the rules around abortions anyway. It's a political instrument at this point. Either side is trying to win, not do what's right, and that's how things have gotten so extreme.

Because I'm pretty sure you can bring pretty much any prescribed drug in its labelled dispensed container — even the Desoxyn! — with you over the border into the US. So it'd be weird if THC was an exception to that; and doubly weird if just having ever been prescribed THC was worse for you than literally carrying a pill bottle full of meth in your bag.

For strings, I believe Rust's approach of a dynamic `String` and a view `str` is the right approach.

For a minimal std, maybe Zig can have a standard `str` type which is used for all functions that don't need to grow the string and the `String` type is provided by any 3rd party library which is expected to provide a conversion function from `String` to `str`.

These strings types could or could not have a requirement of being Utf-8. Maybe there is a builtin wrapper to convert them. So you can any dynamic byte array which can be converted to `str` (just a pointer and length, no validation) which can be later converted to `utf8` (str but validated). A `String` which guarantees Utf-8 could directly convert to `utf8` to save validation costs.
>> was a giant compared to most animals that lived in the seas at that time, most of which barely reached the size of a pinky finger.

A statement that is equally true today. We live in a time of giants (modern whales are the largest creatures ever) but the vast majority of creatures in the ocean remain very small.
Saw this Veritasium youtube video a year ago and the technical complexity required to fly on Mars was shocking to me. Since the air density is super low the blades need to spin at a speed which nears the speed of sound at the blade tips. Crossing the speed of sound causes mini sonic booms which could disrupt the flight entirely. Kudos to NASA scientists for this technological breakthrough!

There's a lot of comfy middle ground between "I do not want any medications; I will go home and wrap myself in a linen shroud" and "please break my nonagenarian ribs then barely sustain me in purgatorial discomfort as long as technology allows".

> I am really not sure why it hasn't caught on in software. I suppose the challenge is that you need to have specifications for what the outcome should be.

In my ~ 20 year career, I hardly ever got a real specification for what should happen when things went right. It was very hard to get people to even acknowledge that things could go wrong, let alone specify what should happen in that case. Almost always, they'd suggest something should never go wrong, or we should fix whatever it was that was going wrong, etc. Which sure, that'd be nice, but really everything breaks, so what do you want me to do when it does?

Start a small hobby farm. It is physical (often exercise though you can design to preferences) and involves gaining visceral experience of the ebbs and flows of the seasons, connecting you more to the ecosphere. The vegetables, flowers, or other plants you grow sustain you and can reduce your environmental footprint. If you keep poultry you can start replacing some of your meat consumption with eggs. You can involve community or not according to your socialization thresholds.

I don't think many Americans have much sympathy for Chelsea Manning. Only a very tiny bit of the trove of data that she dumped was really "whistle blower" material. Most of it was actually strategic military data during an on-going conflict. She was not in any way careful about what she was dumping. At least Snowden was careful to only release certain things.

And also the part where she tried to starve herself to force USA taxpayers to pay for her gender transfer surgery while she was serving a 35 year prison sentence for betraying them...

Tough question!

TMS is fairly common tool for neuroscience research and its effects depend on where, when, and how it is applied, as well as the quirks of each person’s own anatomy. This paper has a table of some studies reporting “beneficial” effects, mostly on perception and memory: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4083569/ There are many more studies showing that TMS (transiently) impairs performance too.

We don’t totally understand how it works—-or what’s normally required for many of these behaviors—-so it’s hard to give a grand unified theory of how it acts, but it definitely does something to brain circuits. That said, the FDA approved TMS treatments for depression and a few other indications, and it’s also used as a tool for neurosurgical planning.
Earth gets multiple orders of magnitude more heat from the Sun than humans can ever hope to generate. In concrete terms, Earths gets 153 PW of energy in terms of solar radiation. It also radiates as much. In comparison, humanity uses something like 20 TW in total (that includes not only electricity, but also transportation etc). So, we could increase our energy use 100 times, and still be only around 1% of what we get from the Sun.
I read the posting "How doctors die. It’s not like the rest of us, but it should be" and it reminded me of a RadioLab podcast I listened to on the radio a couple of months ago while I was driving around one Saturday afternoon. Being in my sixties it was very impactful as I am facing the reality of my mortality. Statistically speaking my day will com sooner and not later. The pod cast was actually recorded in 2013. It includes a segment where they interview Ken Murray the author above. It is a very illuminating story. The medical profession knows what the rest of us don't. Everyone should listen to this no matter your age. Everyone should face this question because you are either old and facing this in your life or you have parents or grand parents and you should all look deep inside and be prepared.

Hi Andy, I'm really intrigued by Zig's features - you're definitely solving the right and hard problems for C developers like myself.

If I may, my only piece of feedback (as someone who looked at Zig with fresh eyes) is that the syntax has lots of special chars (@, !void, .{}, &, etc). Is there a rationale published for these and other design choices (even if it's "I like it that way"). I would have expected a language with ambitious goals like Zig to take a stab at coming up with a grammar that's even simpler and cleaner than C.

Regardless, getting a new programming language working, noticed and used is monumental effort, so I wish you best of luck with Zig!
I think it's just the overwhelming trend on HN. You can see from the top comments on this post that HN is a hive of far-right edge-lordism and LARPing outrage about imagined injustices.

Edit: Then again, usually you can filter out these posts just by the topic and not click on them, which is what I usually do. But the title of this one could have gone either way so I got fooled in to clicking on it. So maybe judging by this post would give a misleading impression about the whole community on HN.

That is unknown because the randomized trials that have been done so far have been too small to show an effect at a p<.05 level. They have generally shown a positive effect for ivermectin though and thus the need for a big trial to settle the matter. There are a couple of big trials in progress so hopefully we will have some more clarity on this soon.

The HN consensus has been that there is no shortage of labour as long as you can just pay more and get the labour. Even the fact that prices are consistently increasing doesn't mean that there is a labour shortage. It's only a shortage if you cannot buy labour at any price.

It is not what you specifically are arguing here, but I have read different iterations of the above dozens of times on HN and it is always highly upvoted and almost all comments are in support of this position. I find it interesting that you can just pay more to buy or rent in SF, so by this definition there is no housing shortage in SF.
