That work has been pretty thoroughly debunked. What's getting transferred is stress hormones, and you can "duplicate" the results by using animals that have been stressed (but have never seen the maze) as the donors. They don't know anything about the maze, so can't transfer any knowledge. The recipients do better in the maze because they are more alert, due to the transfer of stress hormones.

Fantastic breakdown -- very much appreciated. I don't mind creating a new email address if needed, even though I've had this one for over a decade. What you mentioned are very real risks that would be catastrophic should they actually come to fruition.

I'm taking some networking courses online which will hopefully help in terms of being more tech literate and being able to do this.

Regardless, I'm definitely going to start the transition. I also use their cloud storage and have very important documents in there.

Thank you for the education and the heads up.

It drives me absolutely bananas that the "interpretation" (fancy museum word for "signs") at science museums is so parsimonious. Some fascinating device vital to the history of an important branch of science will have a brief paragraph about the person who invented it, nothing about what it's for, and then just a date and the device name.

Often there's little or nothing further even in the museum shop. It's a crying shame.

A company that systematically speeds is a nice fat piggybank for governments wanting a little extra money in their budget or a political win. These vehicles are logging their current locations and speeds constantly against a map of known speed limits. It's much easier for a government to request those records and assess a fine than go after individual motorists with politically unpopular measures like speed traps and traffic cameras.

I hate this bifurcation.

I almost never want 2-hour documentary style videos, yet 1-minute teasers leave me even more dissatisfied.

I want 5-minute to 15-minute videos. They can be either overviews or summaries that cover broad stretches or super focused essays that go deeply in depth on just a singular hyper-focused point.

Long-form typically means opinionated and written for a lay audience. Filled with unnecessary pregnant pauses, fluff, and breathing room. Historians trying to craft a narrative.

Stop wasting your viewer's precious time on b-roll or building a case. Smart audiences will trust you if you're succinct and factual.

So take the heinously verbose documentary format, trim it down to just 10 to 15 minutes, and you're left with a fast-paced, frenetic, fully dehydrated, factual blow-by-blow.

That's the sweet spot. Maximum information density.

> Palestine is not a country.

Of course it is: "As of March 2025, the State of Palestine is recognized as a sovereign state by 147 of the 193 member states of the United Nations, or just over 76% of all UN members" [0]. Yes, the world has decided that Palestine is a country, just like it did for israel, and the few countries that don't like it can sit and stew, because their feelings on the matter have been voiced, heard, and outvoted. Indeed, any argument that Palestine is not a country applies equally to israel, and disclaiming the existence of Palestine as a country is at least as vile as disclaiming the existence of israel as a country. What does israel call people who do that?

> I dont think anyone deserves anything.

Nihilism is a valid opinion to hold, but while I'm sure you're a good person, what any 1 person in the world thinks, is a fraction of a billionth as relevant as what the majority of countries think, and the latter is clearly codified in international law. In short, the debate of "does anyone deserve anything?" was already held, the side of "no" lost, and the world doesn't currently seem interested in israel's desire to re-debate the matter.

> The question is, is it is moral for me to force israel to put up for terrorism

That is a question, sure. An equal question that must be addressed simultaneously is, is it moral for us to force Palestine to put up with israel's terrorism? They are, after all, 2 co-equal countries with equal rights.

> The holocaust had nothing to do with the nazis defending themselves.

Likewise, israel's holocaust of innocent Palestininan civilians has nothing to do with protecting itself. The unconvincing claims of self-defense israel has made, exactly mirror the unconvincing claims of self-defense that nazi germany made: In both cases, the genociders have claimed their genocide is righteous because they are the chosen people; and their victims deserve it because they're lesser, they're not even people, they're "animals" (quoting both israel and nazi germany here); and certainly the chosen people must defend themselves from animals, and of course that means cleansing the land of the animals and availing themselves of their god-given right to rule over it in ethno-religious supremacy forever.

That doesn't sound like "self-defense" to me. Never again means never again.

They put reading a book and watching slow paced television in the same category, which to me seems like a category error entirely. I see nothing wrong with avoiding slow-paced video… life is short, time is precious. If slow video is not your thing, that’s fine. However, books are a different matter entirely. Not all books are worth reading, but being unable to read any book is definitely a sign that your attention span is suffering. Some books are low-intensity, but some are quite high-intensity, and everything in between. But regardless of where they are on that spectrum, all books require an attention span greater than the one required to watch TikTok videos.

My attention span went (back) up after I forced myself to read some books start to finish. It’s something you can lose, but fortunately it’s also something you can regain.

The Exploratorium had a few speakers at the adult night that I went to. It was definitely on the pop-sci end of the spectrum, but it was definitely not dumbed down to kid levels. Heck, even during normal operations, I'd say the Exploratorium walks a fair line between "approachable to children" and "teaching more science topics than we expect most adults to know".
Show HN: FindMyMoat – Directory of Investing Tools
by jera_value | 2025-09-10 17:09:38+00:00
I kept losing track of all the random tools i use for investing research; from screeners to niche data sites. so i started collecting them in one place: findmymoat.com.

it’s just a simple directory right now, but the idea is to make it easier to discover and compare tools (fundamental, quant, options, whatever).

curious if others find this useful, and if you have favorite tools i should add.

That's pretty much only an Amsterdam thing, and it is limited to a relatively small tourist-centered area. Even inside the Grachtengordel the majority of buildings are homes or offices.

Also, those "suburban" areas in Amsterdam aren't suburban: they are still built with a bicycle-, pedestrian-, and transit-first mindset. Those office buildings in Zuid are built right next to one of the busiest railway stations in the country, and the highly-paid lawyers will arrive at the office by bike from their nearby homes.

If you want Amsterdam's suburbs, you'll have to go to Almere: it was literally built as a commuter city for Amsterdam. And even there you'll have trouble finding areas which don't meet the definition of a 15-minute city.

This is terrible to say, but if 170 million people are spending an hour a day watching 60 second videos, aren't they just dumb and easily entertained? Without this, wouldn't they just be consuming other dumb entertainment, or failing to find that dumb entertainment, going outside, and meeting other dumb people in order to do stupid things?

Also, I'm sure I have to subtract a huge number of these people from the dumb list, because they probably just watch a bunch of TikTok to unwind or get summaries of the events of the day, then move on to real content. People spend a lot more than an hour in front of screens, and have for the past 75 years. Plenty of the world was already watching dumb short animal videos, fail videos, success videos, astonishing videos, etc. long before TikTok.

Early youtube absolutely despised and made difficult uploading videos over 10 minutes. The thing was made to share tsunami videos and what were basically animated personal snapshots.

Acting like this is a qualitative change is just easy ragebait, and this story has been written again and again since MTV debuted (which is why it felt the need to refer to it.) That was almost 50 years ago.

Easy backups, especially for repos that use Git LFS. It's also nice to have a simple UI for browsing repos and project history. Soft Serve doesn't have built in CI/CD, but I plan on bolting on a lightweight solution there.

I have hundreds of random tools and half-finished projects, having them all accessible and searchable from a single location is convenient.

Agreed. They make it into a space for adults by simply removing kids and adding beer. It’s good for a casual date, but you don’t actually get adult level content.

I want the actual exhibits and content to be able to teach things to adults and not just signs with “wacky trivia” meant to engage kids for two seconds while they sprint to the next thing that has a button for them to push (e.g., one of the worst genre of “wacky facts” are stupid size comparisons about how things are bigger than X football fields or Y school busses).

Tl;dr You could get drunk while you’re watching Zoboomafoo, but that doesn’t suddenly make it it for adults the way that an Attenborough documentary is.

What good is the gun doing in their car?

Are they going to leave, get their gun, and come back? That is almost certainly illegal, and stands a very good chance of shooting the wrong person. That's why the gun is in the car -- it's not allowed into the school.

Their top priority is the children in the room, which usually means sheltering in place. If it were easy to get the children out we wouldn't have mass shootings in the first place. Are they going to leave the kids alone while they fetch their gun?

They may like the idea of playing the hero, but there is basically zero chance of that. There is no opportunity to get their gun and a billion problems with using it if they had it. It's a comfort blanket, not a tool of protection.

Well, panhandling was just one thing mentioned, and to focus on that to the exclusion of the others seems disingenuous.

But it does depend on the nature of the panhandling, doesn't it? Passive panhandling is one thing, and aggressive panhandling is something else, right?

The point is that people will accept some level of anti-social behavior, however they define that, and above that level they do not. No amount of bluster or "why I just never" or incredulity doesn't change that. If you want walkable cities with good public transit you make it attractive and hospitable to a wide majority of people.

Or don't, no skin off my nose, but acting shocked that there are people who think and react differently than you do is silly IMO.

> But that's not how real life works at all, right?

oh of course! Sorry, I was never trying to imply that that it was in any way realistic. For video games often the most fun / compelling choice is not the realistic one! Striving for realism can be a great goal and often has a lot of positives, but it is often limiting. Video games are just art, being photorealistic can be beautiful and amazing but is often not the best choice for expressing an idea.

Not that I'm a fan of tipping culture or the "creator" economy, but it seems like tips and donations to your favorite youtuber are obviously gifts to me? From irs.gov:

> You make a gift if you give property (including money), or the use of or income from property, without expecting to receive something of at least equal value in return.

Which is obviously true for tips and donations. If it is a gift, then the giver owes taxes, and there is a $19k/year/recipient exclusion, so small gifts like this would always be exempt.

I do agree that it's not the panacea some people are hoping but true self-driving would change the experience for many people from a couple hours a day of not doing anything other than listen to music / podcasts / audiobooks to being able to do real work if they have things which can be done a laptop. Since multiple generations have been moving further out to car-only suburbs, I think that'd be very popular even if it's still not as nice as having a shorter commute.

>I'm also fairly certain that Vance did not wander the streets of Middletown, feral and unparented. My understanding is that he was raised by his grand-parents, not that he lived with the chaos of his mother's situation.

So an addict mother, having to be raised by grand-parents, having to go to the army and then use the GI Bill to study, growing up in an declining small working class town in Ohio, are not enough?

He had to be "feral and unparented" to qualify? Because that's what people mean when they talk about the working and middle class "white American struggles"? Vicorian street urchins?

In any case, by those elements alone, he knows 100x about "white American struggles" than the average champion of the poor at the Met Gala and the New Yorker.

I've hedged the stability risk by using the narrowest possible slice of the framework.

With enough experience you can accomplish pretty much everything using just the minimal API and router. HttpContext is the heart of AspNetCore. If you can get your hands on instances of it within the appropriate application context, you can do anything you need to. Everything else is dependent upon this. The chances that HttpContext can be screwed with are very, very low. There are billions of dollars riding on the fact that this type & API remains stable for the next decade+.

Vance grew up with middle class access to stuff like stable housing, food in the fridge, his grandparents had stock and pension plans, he peppers his book with spicy poverty stuff like finding a weed plant or second hand stories of blood fueds to vet hillbilly cred. There are many middle class families that go through similar shit, but the common black/latino poverty experience often involves surviving narco gang cultures, ambient verbal and physical harassment among friends and family where calling the cops isn't an option, or coercive sex or rape at an early age. Urban poverty is an entirely different beast where you witness 12 year girls olds being given MDMA and entering the sex trade, later having to go to witch doctors or cauldron chemists for improvised poison abortions because Vance's party demedicalized the practice in your state.

The data you present does not say that:

> 35% des cyclistes tués, 63% des cyclistes blessés gravement le sont dans un accident sans autre véhicule impliqué.

35% of cyclist deaths, and 63% of cyclist seriously injured occur in an accident with no other party involved.

Another graph in that report shows that a vast majority of cyclist deaths occur while cycling for leisure. I would hazard that most cycling in cities is utilitarian.

Because they target heavy vehicles, SUVs have no proper definition. But many decent family-friendly cars for 3 children with a large boot are in this category. In general, the city has greatly reduced surface parking, which creates a lot of problems for trade workers who need to intervene in the city and need a car.

On the Mac side, can confirm how useful this is. As soon as transparent text selection in images was added to iOS and macOS, it went from that being a feature I'd never even though about, to becoming a table-stakes feature for considering a GUI platform basically "complete". It's very weird and annoying when I'm on something that doesn't have it, now. Crazy for a piece of functionality I'd never even thought to try to find a solution for, until it was simply handed to me and worked automatically.

That’s because restic is not opinionated about where and how you store your backups. Restic provides a nice interface to create the backups, and then lets you choose where you want to store them (and how access to them is managed), be it locally or via SFTP or S3 or many other backends. Any security properties related to S3 are not in the scope of what restic is meant to do.

It’s pretty simple to enable versioning and object lock on your S3 bucket, but it is another step if you’re using restic. Sure, if you just want all of that taken care of for you, you can use tarsnap, but you’re paying a 5x+ premium for it.

The other nice thing about restic is that since it’s just the client-side interface, it allows others to provide managed storage. Borgbase.com is a storage backend that is supported by Restic that supports append-only backups, and is cheaper than tarsnap.

I was laid off in May 2023. At that point I had been a JavaScript developer for 15 years. I was sad at the loss of income, but this became a huge positive for me.

I had grown really tired of JavaScript employment. I love writing applications in JavaScript/TypeScript and continue to spend a significant portion of my personal time doing so, but I cannot stand JavaScript for work. I felt like I was constant surrounded by people who couldn't program, couldn't write emails, and really could function in any real capacity without copy and paste of familiar programming patterns.

Being laid off for 6 months was really stressful and I really began to double myself, but now I am in a different line of work and its so much better. Soon after joining this new line of work I was promoted into management of a software team.

I suspect that chat apps dominate (80+%?) the under-20 demographic, and have a sizable chunk of the under-30 demographic. Within the next five years it will probably represent 50+% of total search traffic. Maybe it already does. It makes sense that any search site that wants to be in the game tomorrow would keep racing down the AI chat path.

Not Paris, but I lived in an even larger metropolis (Beijing) for 6 years, with two young children, without a car. We took public transport and/or rode bikes most of the time, and took taxis when neither of those were possible/convenient. Even with the taxi fares it was much cheaper than owning a car.

> Another negative aspect is that cyclists do not use public transportation,

For short trips maybe, but as a cyclist myself, I'd say cyclists are among those most likely to use public transportation for any trips that are beyond their cycling radius, or where cycling isn't feasible, instead of a car.

That's disappointing. I liked to believe it would remain an example of a good museum after other places followed this trend. But on the west coast, I've had no reason to visit the Smithsonian in many decades.

I'm still unsure whether changes I see are all about the facility or partially about my changed perspective. I visited the Monterey Bay Aquarium and the La Brea Tar Pits in the past decade, and I found neither of them stands up to my memory of them from 1980s school field trips.

>At the same time, YouTube videos are getting longer, and people are watching more YouTube videos on TVs than on mobile devices

I wager most people are putting those on while having a meal and using their phones or tablets at the same time. Moreover, 99% of the most watched content on YouTube is utter garbage that would make the average reality show on TV twenty years ago look like The Godfather in comparison. Gossippy, clickbait videos made to induce an immediate dopamine dump and be used as background noise aren't "in-depth" anything. I don't think people are sitting in front of a TV watching an hour-long, non-sponsored, ad-free interview with Margerite Duras and doing nothing else concurrently, for instance.

On top of all that, this trend of making longer videos comes mostly from an attempt to increase ad revenue. Let's not be fooled here.

Yes. I went to a very nice suburban public school. As did my offspring. But it seems somehow... thermodynamic... in order to maintain the quality of our suburban public schools, we have to take more and more resources away from other schools, in less well-off neighborhoods.

This linked article and the comment section remind me how I admire American maximalism. No half-measures - want to be able to drive everywhere? Let's bulldoze whole cities to make them car-oriented. Tired of the concept after a few generations? FUCK CARS, let's have Pontevedra everywhere.

Meanwhile there are places in the US that managed to preserve a more balanced approach. Take for example the borough of Mechanicsburg, Pennsylvania:

https://maps.app.goo.gl/Fgs9pBLmGCgWbtLGA?g_st=ac

At first glance it looks like a typical car-oriented landscape, but note the presence of sidewalks. There's on-street parking, but hardly any driveway visible, because they're at the back, connected to one-way alleys.

That is brilliant. On one hand the area is fully walkable, on the other everyone gets to live in their detached house with a garage and whatnot. You can drive, but you can also walk. Hell, you could probably even cycle through those alleys as cars use them only to park, so they won't be speeding through there.

And the wonderful hands-on physical stuff that I loved as a kid? Jammed into out-of-the-way spaces in the Sir Isaac’s Loft and Air Show rooms. These rooms are terrific, and I was delighted to see they were absolutely packed with kids playing with stuff.

I'm really not sure what the problem is, given that these exhibits are there, popular and obviously accessible. Ok, the author has an issue with screens, but, hey, a lot of real science is done on screens today...
