I made an account to sell a cheap guitar. I listed it for $100 and used all my own original pictures.

They said my listing was suspicious and needed to verify my identity, which meant sending them a picture of me holding my drivers license next to my face.

I had a lot of other stuff to sell, so I obliged.

They said that wasn’t enough and they required another photo, this time holding my passport by my head.

I thought this was pretty crazy, but also, I had a lot of stuff to sell, and privacy is pretty much already dead so why not?

They said they could not verify my identity.

The end.

It's an app and a device. I do /love/ that on Android phones the Apple TV app can ONLY play Apple TV+ content whereas the Android TV and other Apple TV apps can play iTunes Store content which they may or may not allow purchasing in the app. It's a really great consistent system.
Oh ick. That's not so good. Hope they can firmware-update their way out of that. It's odd that they've got that problem because my experience with the tracking on the Airs with the desktop software driving it has been pretty much fine.
My memory for names is abysmal if I just hear it, but if I see a name written down, then I can remember it as well as most people. It's terrible if I'm introduced to people as their name goes into my ear and I almost instantly forget it, even if it's repeated. Once I see it, though, I'm usually very good.

I had a similar issue with learning French at school - we had a teacher that would just speak the language and get us to repeat it. That was just terrible for me as I had no idea what was going on as I had difficulty learning it despite being very academically gifted. After about 6 months or so, the teacher started using textbooks too and once I could read the words it all became so much easier for me as I could visualise how to pronounce the words etc.

I would love to read more about all this, especially how overlays came from "object-oriented" programming. To me, the interesting part is their self-referential nature, for which lazy eval is indeed a great fit!

For anyone interested, this is how I'd illustrate Nix's overlays in Haskell (I know I know, I'm using one obscure lang to explain another...):

data Attr a = Leaf a | Node (AttrSet a)
deriving stock (Show, Functor)

newtype AttrSet a = AttrSet (HashMap Text (Attr a))
deriving stock (Show, Functor)
deriving newtype (Semigroup, Monoid)

type Overlay a = AttrSet a -> AttrSet a -> AttrSet a

apply :: forall a. [Overlay a] -> AttrSet a -> AttrSet a
apply overlays attrSet = fix go
where
go :: AttrSet a -> AttrSet a
go final =
let fs = map (\overlay -> overlay final) overlays
in foldr (\f as -> f as <> as) attrSet fs

Which uses fix to tie the knot, so that each overlay has access to the final result of applying all overlays. To illustrate, if we do:

find :: AttrSet a -> Text -> Maybe (Attr a)
find (AttrSet m) k = HMap.lookup k m

set :: AttrSet a -> Text -> Attr a -> AttrSet a
set (AttrSet m) k v = AttrSet $ HMap.insert k v m

overlayed =
apply
[ \final prev -> set prev "a" $ maybe (Leaf 0) (fmap (* 2)) (find final "b"),
\_final prev -> set prev "b" $ Leaf 2
]
(AttrSet $ HMap.fromList [("a", Leaf 1), ("b", Leaf 1)])

we get:

λ overlayed
AttrSet (fromList [("a",Leaf 4),("b",Leaf 2)])

Note that "a" is 4, not 2. Even though the "a = 2 * b" overlay was applied before the "b = 2" overlay, it had access to the final value of "b." The order of overlays still matters (it's right-to-left in my example tnx for foldr). For example, if I were to add another "b = 3" overlay in the middle, then "a" would be 6, not 4 (and if I add it to the end instead then "a" would stay 4).

What a great find. Not sure why I have not discovered Prot before. Bookmarked the article and this thread.

I have been using Emacs for about 40 years, and as a crazy side effect of the mountain of LLMs hype, with a lot of productivity enhancing goodness, I think that Emacs can only gain in popularity because of several excellent Emacs LLMs packages. Most of the world is exploiting LLMs with VSCode and its variants, but Emacs is also just about perfect for integrating LLMs into workflows and for having fun and playing around.
By default, yes. There is an option when creating a "channel" to make it on-demand too.

Schizotypy was doomed to obscurity by Gordon Claridge and his frickin' conference proceedings. As opposed to the taxonic concept of Meehl where it is some condition you have or you don't, they just wrote numerous papers where they graded people on scales so now there is a "psychoticism" scale that competes with the "neuroticism" scale of the Big 5.

The DSM diagnosis for STPD

https://en.wikipedia.org/wiki/Schizotypal_personality_disord...

eluded me for a long time, it was when I came across Meehl's concept as articulated by Lezengreber

https://en.wikipedia.org/wiki/Schizotypy#Development_of_the_...

in particularly items (3) and (4) that made me understand why my life went the way it it did. Meehl postulated that schziotypy has a developmental disorder schizotaxia which then leads to negative social learning that causes it to become a personality disorder, it's a mistake to look at it primarily as a PD.
Well, this looks legit, as this is a real domain registered in 2022, but I still don't get why would you make a new post on a freshly registered domain after a 3-year pause and immediately submit it to HN.
> These are little bit different than than what a swappable system would entail, aren't they?

From an electrical point of view, swapping batteries is fundamentally the same general problem regardless of whether they are large or small: you want to avoid arcing when the connector is plugged in, and you need to avoid exposing the user to stray voltage. Sure, there's added complexity to achieve that in a safe and cost effective manner when high voltages are involved, but it's a solved problem as the charge port does exactly this today.

> Okay maybe I miss read the initial premise but I took it as a home user swapping in-and-out modules themselves.

Current EVs on the market suffer from decreased maintainability compared to traditional ICE vehicles. The battery swapping skill set needs to be more widely available so that we don't see EV owners being dinged $40k for a battery swap. There are videos on Youtube showing people doing a battery swap themselves, and while it is challenging, it's not all that hard to do safely when the battery is not damaged given that the battery packs don't expose high voltage on the connectors when not enabled. Of course a damaged battery pack means that all bets are off on the safety front depending on the nature of the damage.

> That would appear to me to be a significantly different engineering challenge and safety issue than what's currently deployed in consumer market EVs...

> I'm not even sure the small upside here would justify the added costs and complexity either.

It a solved problem!!! Just put the charge port at the back of the vehicle and then use it for the add-on battery pack like the existing signal light connectors for trailers. You're done. The only added design constraints on the EV are on the location of the port and verification that it works while the vehicle is being driven. The F150 Lightning fails this today since the charge port is just in front of the driver side door, but relocating the charge port is not exactly rocket science.

Many EVs have already taken the step of making the charge port bidirectional so that the expensive battery in an EV can be used to provide power during an outage or to balance the load on the grid, and that is a far, far more complicated problem than accepting power from an external battery pack through the charge port while the vehicle is operating.
> In this case, a deferred call to close the channel in HandlePlayer is sufficient

It is not clear from the example, but I presume there would multiple players, i.e there will calls of the form:

g.HandlePlayer(p1)
g.HandlePlayer(p2)
..

in such a case one player closing the channel would affect rest of the producers too.

Google Search is 95% unusable as of 2025. I don't want to use it anymore (as opposed to always wanting to use it because it did the job best). Search results it offers are either paid or LLM generated garbage. From Google's perspective, it is insane to destroy the quality of a market-leading product like this, or it is very intentional to drive users to LLMs for much better user manipulation and cashing opportunities. Of course, at some point users must pay LLMs. They will become like O365, it is just mandatory to pay at least 4,99/month at minimum.

It’s a lovely piece, but maybe goes a bit too far in trying to paint Lem as some kind of human-form planet Solaris himself, failing to communicate with ordinary people. For example:

“These essays are the work of a lonely man. We can judge the fervor of Lem's attempt to reach out by a piece like ‘On the Structural Analysis of Science Fiction:’ a Pole, writing in German, to an Austrian, about French semantic theory. The mind reels.”

That just sounds like an ordinary letter for a 20th century European intellectual. Reading and writing in French and German was table stakes.
Surprising no one. This pipeline should never have been approved in the first place.
At this point, my cynicism assumes that the only answers they will be willing to accept are things they've already decided they don't like.

"We've found that cheap foreign imports cause autism!" or "A holiday in Greenland will cure autism!" or "It's a curse from God for turning away from Him, we must end the separation of Church and State!"

Thanks for your reading:)
MIT 6.S191 Introduction to deep learning
I an others in this thread know why this won't work but let's not discourage them. Let them confine themselves and all their utopian / dystopian tech in their little cities and let all the people that blindly adopt this tech move to those cities. Then we just have to figure out how to encourage them to not leave those cities.
Its true in theory, but it does not work well in practice because:

1. Developers have to make an extra effort (and require time) to do it right
2. People are much less likely to learn the keyboard shortcuts

If you designed a GUI to be keyboard first then it might work as you say, but I cannot think of any real life examples of that. I think people need to TUI look to push them to use keyboards.

Gotta look at your monthly bill every day.

I've been wondering about the question of "where did the web go?" and how even technically savvy people have given up on blogging for behavioral sinks like Medium.

Part of the story is that $50 a month dedis have given way to the "free" plan on AWS or a system that costs $10 a month to run if you're not successful but has no upper bound on the bills if you are successful. So if you make a blog you are praying every night that you don't make it to the front of Hacker News and that you don't build up a large following because boy those egress charges will add up. People are furious now that they are getting eaten alive by the egress costs run up by AI bots but 10 years ago I was thinking "Boy Bing crawls my site twice as hard as Google and sends 5% of the traffic and Chinese webcrawlers crawl my site 5x harder than Google and send me no detectable traffic."
This was great - thank you!
Sadly, that situation is also contorted to legitimize the spread verifiably false information by certain current political cults, led by a Turnip, that claim it is another party controlling media because they believe that they have the secret access to the “truth” that is being “blocked” on all other sources of media, and point to other suppressed stories (even if completely unrelated or blocked due to being outright lies) as proof. Look at attempts to curtail the spread of completely false vaccine information that is now being used as proof of something nefarious (even while more nefarious activity is being perpetrated). Some people took notes from other Dictators’ control of media long ago and have been working toward it for many years via press-related misinformation to cause a loss of confidence. You would think the press would fight back harder against being de-legitimized, using stronger wording and calling lying what it is, but when your purse strings are being controlled by the same businesses that see opportunities to advantage themselves, it’s not surprising.
It would answer my question properly if I'd seen that it looks just like the stock Android UI, so even though it's almost exactly the same, that's still quite valuable for me rather than pointless.

I've also done some image search and it does change a bit with apps and they look quite good. So I'm still baffled why this aversion to images is decided. Or just overlooked maybe?
Facebook was awesome when it was the only social network; now we have Instagram for social image sharing, WhatsApp for messaging, Snapchat for ephemeral messaging, YouTube for social video and TikTok for social short video plus Discord and Twitch for social gaming. Even Facebook's social casual gaming moved to mobile gaming.

Facebook wanted to be the everything social network just like Amazon is the everything store but it doesn't work because we began to see specialization for every segment of Facebook. I honestly don't see appeal why anyone would use Facebook when you literally have better alternatives that are specialized for the particular niche you might be interested in e.g. images, videos, gaming etc.

> Business doesn't operate on the benefit of society. It's not a charity.

Which is why we have legislation to force them to act in given ways. I'm not suggesting companies should choose to do it, I'm saying we should pass laws to force them.

> They have? No they haven't. There are already ongoing law suits.

That was in the context of the hypothetical where training models is just considered a type of copying and handled by existing copyright law. You seem to be misunderstanding my points as a cohesive argument about the current state of the world: I was describing possible ways to handle legislating around machine learning models.

> How do you? Send the NSA and FBI to everyone's house? How do you know I have a model?
> Just like stopping drugs? Good luck.

I answered this in the rest of my comment? I don't believe the comparison to drugs is at all reasonable: it's much easier to manage something large companies who have to operate in the commercial space do than something people do on the street corner.

It appears you aren't really engaging with what I'm saying, but giving knee-jerk responses, so I don't think this is going anywhere.

The answer is probably "because the alternative is worse". I too would rather make a single web app than separate Tizen/tvOS/WebOS/Android/whatever Roku runs apps.
This aestheticization of factory jobs is something I've noticed to be driving the New Right's worldview. It's not dissimilar to and no less dangerous than the aesthetic fixation on the agrarian economy of Mao and Pol Pot.

Frankly, no, sweatshops are not important to the cultural fabric of a country.

The US has problems with housing affordability, with medical costs, and with service sector costs emerging from Baumol's cost disease, which are all things that will get worse with tariffs, ranging from higher construction costs, to higher pharmaceutical prices, to less service employees making the cost disease worse.

It's also untrue that comparative advantage only benefits capital. Consumers are hurt by higher prices and less job opportunities driving down demand on the labor market. This worldview of a zero sum contest between capital and labor is a populist fiction.
The statement is technically true, but slightly confusing because the article talked about orbit being free fall, and about microgravity being in the range of one millionth to one thousandth of earths gravity.

It is certainly possible to get far enough away from anything that gravity is far less than one millionth of earth’s gravity, so it’s no longer microgravity by the article’s criteria. Floating freely would be free fall, but that doesn’t exactly mean what it sounds like when gravity is negligible.

The article also didn’t clarify that at our typical orbital distances for ISS and satellites, gravity is not in the microgravity range, it’s still very strong.
> I'd imagine the times I'm rushing to work and have to stop for gas would get a lot worse with a long charge time.

Of course. That's where my other comment is relevant: " "very fast charging" should not be the default, it should be rare. ... the default is overnight at home or during the day at office or a mall, with the software giving you that "topped up as specified, every morning, that's better than what an a ICE vehicle can provide"

https://news.ycombinator.com/item?id=43671612

i.e. with an EV and commute, you can slow charge and also never "stop for gas", ever. The vehicle is just ready, every day.

If you "don't live in a place where you can have a car charger" at home or at work, then IMHO an EV is not ideal for you, yet. The infrastructure isn't ready for you, work on that first.

What a lovely sentiment. Fully agree; staying in the terminal for as much as possible makes for far less friction when context-switching.
> We do not use channels to increment a shared number, because that's ridiculous and the author is disingenuous in their contrived example. No serious Go shop is using a channel for that.

Talk about knocking down strawmen: it's a stand-in for shared state, and understanding that should be a minimum bar for serious discussion.
Agreed. This is an overblown explanation of a protocol for API communication between agents. Nothing more.

It could be useful if setup in a way that works for you on both ends. And we all know how likely that is with anyone else's API. Also, if you use MCP, you will be the one setting up your tool calls to use that protocol, when you could do them directly any way you want to. It's extra scaffolding that's not always an advantage by itself.
