> Humans do the same thing. We get stuck on ideas we've already had.

Not in the same way. LLMs are far more annoying about it.

I can say: I'm trying to solve problem x. I've tried solutions a,b, and c. Here are the outputs to those (with run commands, code, and in markdown code blocks). Help me find something that works " (not these exact words. I'm way more detailed). It'll frequently suggest one of the solutions I've attempted if they are very common. If it doesn't have a solution d it will go a>b>c>a>... and get stuck in the loop. If a human did that you'd be rightfully upset. They literally did the thing you told them not to, then when you remind them and they say "ops sorry" they do it again. I'd rather argue with a child

Can you explain the shadow banking / conversion angle? All I found was that selling knives was used to get a discount on steam balance thanks to price arbitrage.

> "Selling Knives" (挂刀) refers to the technique of buying in-game items from 3rd-party (Chinese) trading sites like NetEase BUFF, C5, IGXE, and UUYP, and then selling them on the Steam Market to obtain a discounted Steam Wallet balance by capitalizing on price differences.

I'm surprised the price difference did not disappear if people make that trade.

> DC has a lower risk of shock than AC, because it still usually can't drive enough current through your skin to kill you

What? Common wisdom is that DC shock risk is worse than AC, as DC makes your muscles clench up and so it's harder to let go of whatever you grabbed. That "120Vac" is actually 170V peak though, which does increase shock risk for equivalent power transferred (maybe this is what you meant?).

Which is an easy technical problem to solve, but the liability of abuse when sharing user content with other users is not palatable.

It is also not impressive to others, not a status symbol, and that's actually the purpose of skins in the modern day. No one grinds 1000hrs of warframe for a skin just because they think it looks cool, they think it makes THEM look cool. They want people to be impressed that they had $2000 to spend on a knife, not that the knife skin was neat. The skin is an auxiliary component to the task.

The borrow tracker tracks whether there is 1, more than 1, or no references to a pointer at any particular time and rust automatically drops it when that last reference (the owning one) goes away. Sounds like compile time reference counting to me :P

I didn't invent this way of referring to it, though I don't recall who I stole it from. It's not entirely accurate, but it's a close enough description to capture how rust's mostly automatic memory management works from a distance.

If you want a more literal interpretation of compile time reference counting see also: https://docs.rs/static-rc/0.7.0/static_rc/

The North American auto sector is propped up by subsidies on both sides of the border.

What the article in the parent post doesn't mention is that Stellantis and GM received massive handouts from the Canadian government to retool factories in Canada, contingent on actually operating those factories and employing Canadian workers. Abandoning them and moving production to the U.S. (because of tariffs) violated their agreements. Hence, no more tariff relief for them.

North American auto companies are between a rock and a hard place right now, but it'd be folly for the Canadian government to let them ignore their agreements without consequence.

TL;DR: It would be more accurate to say Trump tried to steal a cookie from the Canadian cookie jar and is now acting shocked that his hand has been slapped. Canada is merely reacting here, and rather mildly at that. Calling off trade negotiations entirely is clearly not warranted and everyone should expect another TACO Tuesday.

Why? You probably know just how long these cases take, so it is not like all other countries are now going to do the same.

If that's the case then using their total profit seems the only proper measure. What it says is that these companies lose these cases but it's so infrequent that they can just price it in. It's a cost of doing business.

If we were to fine Tim Cook 1000$ for doing something that paid him 1M would that have the 'effect' of keeping him from doing that again?

On Macs, users can download and install apps freely from the internet, and that platform isnt "a morass of freemium games and ad slop".

Why is that for one platform, everything needs to go through AppStore while the other it is OK - and both are equally secure?

Are you sure you're not falling for Apple's reality distortion field?

Respectfully, I completely disagree.

People "at large" absolutely don't care about AI slop, even if they point and say eww when it's discussed. Some people care, and some additional people pretend they care, but it just isn't a real issue that is driving behavior. Putting aside (for now) the idea of misinformation, slop is socially problematic when it puts artists out of work, but social media slop is just a new, sadder, form of entertainment that is generally not replacing the work of an artist. People have been warning about the downfall of society with each new mode of entertainment forever. Instagram or TikTok don't need to remove slop, and people won't care after they acclimate.

Misinformation and "trickery" is a real and horrific threat to society. It predates AI slop, but it's exponentially easier now. This camera, or something else with the same goal, could maybe provide some level of social or journalistic relief to that issue. The problem, of course, is that this assumes that we're OK with letting something be "real" only when someone can remember to bring a specialty camera. The ability of average citizens to film some injustice and share it globally with just their phone is a remarkably important social power we've unlocked, and would risk losing.

I suspect that it's difficult to keep the post sufficiently still that the panels don't fall off those slots? Particularly if there's ground frost in the winters in your area.

Of course it's possible to make it work, but if you need a concrete foundation in the ground to keep the posts immobile you're destroying the economics of it.

Then again, why don't those 'really expensive mounting solutions' suffer from the same issue?

Just do as the other commenter pointed out and install an alternate youtube frontend on your TV. I'd recommend https://github.com/yuliskov/SmartTube. Then you'll never see another ad again (including those sneaky ones that are embedded in the videos).

And you can use the youtube app on your phone to search for videos and prepare playlists.

That is less than 4 of the 32 software-visible vector registers of an AMD Zen 4 or Zen 5 CPU, or of the future Intel CPUs that will reintroduce AVX-512.

There is no difficulty in defining AVX-512 instructions that would operate on a hash state of this size.

The real amount of 64-bit registers in a modern CPU is well above one thousand and the implementation of the SHA-3 functions is very efficient in hardware, so adding instructions for these hashes would have a very modest cost.

That might be true. In my case, it is precisely because I do play a lot with my code, doing big 2-day refactors sometimes too. With Rust, when it finally compiles, it very often tends to run without crashing, and often correctly too, saving me a lot of debugging.

But it's also because of all the things I'm forced to fix while implementing or refactoring, that I would've been convinced were correct. And I was proven wrong by the compiler, so, many, times, that I've lost all confidence in my own ability to do it correctly without this kind of help. It helped me out of my naivety that "C is simple".

This seems like a great place to ask: how does one go about optimizing something like zram, which has a tremendous number of parameters [1]?

I had considered some kind of test where each parameter is perturbed a bit in sequence, so that you get an estimate of a point partial derivative. You would then do an iterative hill climb. That probably won't work well in my case since the devices I'm optimizing have too much variance to give a clear signal on benchmarks of a reasonable duration.

This seems to be a Python based Jupiter notebook (style?) thing for collaboratively working with GIS data/visualizations.

OpenStreetMap is a project to "map the world". In the end, OpenStreetMap provides data (and map tiles) for other things to use.

Going out on a limb (since I haven't used it) but JupyterGIS can probably make use of OSM data, along with other data sources.

In the same way that we don't rely on the assurance of entropy to mix stew however, thermodynamics is not something to base your diet and exercise plan on. We both know you are technically correct, but it doesn't help you to plan your lifestyle change to know it.

That's why it's a frustrating reduction of the problem, the knowledge inbetween helps us make good decisions that involve a lot more than just the physics of the problem.

For someone I know gets it I can just say "eat less than you move" and that is the whole fitness plan, makes sense, but that's because they are filling in all the details for me. When to eat, what to eat, how much to eat, how much and when to move etc etc.

(Bangladesh, not India)

Yes, but solar power panels are also mostly produced in China, where engineers still get less than 1/3 of the US/Europe salary.

European power plants will be more expensive, but even with the LCOE of 12 (twice that of Rooppur) it's still going to be way cheaper than storage for areas that get cold weather (Midwest, Germany, most of China).

Anything south of California? Yeah, just get solar+wind, no need to bother with nuclear.

Heh, few years ago I built myself a RPi Zero based camera.

I wonder how have they made the boot up fast enough to not be annoying.

I used non-real time eInk display to cut down on the battery life so I could just keep it on in my pocket while out taking pictures since it took good minute to get ready from cold boot.

And let's not forget the original Macintosh, which Steve Jobs insisted shouldnt have a fan and likewise tended to overheat. Of course, that was only after learning the lessons of the Apple ///, where

> Jobs insisted on the idea of having no fan or air vents, in order to make the computer run quietly. ...

> Many Apple IIIs were thought to have failed due to their inability to properly dissipate heat. inCider stated in 1986 that "Heat has always been a formidable enemy of the Apple ///",[15] and some users reported that their Apple IIIs became so hot that the chips started dislodging from the board, causing the screen to display garbled data or their disk to come out of the slot "melted".

Not OP, and not that I buy that the App Store serves its purpose given what's currently on it, but I just don't think the two platforms are comparable.

iPhones outnumber Macs something like 10:1. The user base tech literacy is lower on average. The usage habits are different.

The payoff for creating freemium and ad slop stuff on iOS is way higher.

Anything that isn't signed with certs from Microsoft-blessed CAs, anything that is signed with certs that were revoked either by Microsoft or their blessed CAs, and anything newly signed with old certs that weren't renewed for a $100+/yr fee. That, or you upload your app to Azure for cloud signing where Microsoft decides to bless it or not, and you might pay less than going with a full code signing cert from a CA.

Ran into this fun issue a while back[1].

JGIS builds on OpenStreetMap and other open geospatial data sources as basemaps or overlays. JupyterGIS itself is a Jupyter-based interface for working with GIS data—so you can visualize, query, and process OSM or any other data directly from notebooks alongside Python tools like GeoPandas.

Kudos for making this exist, it was an inevitable place for the conversation to lead, and I’m actually glad it was “hacked” together as a project rather than forced into a consumer product. The camera specs don’t really matter here, this is about having the conversation. If this catches on, it will be a feature of every smartphone SoC.

On one hand, it’s a cool application of cryptography as a power tool to balance AI, but on the other, it’s a real hit to free and open systems. There’s a risk that concern over AI spirals into a justification for mandatory attestation that undermines digital freedom. See: online banking apps that refuse to operate on free devices.

LLMs and Humans fundamentally write different kind of code.

As humans we segment functionality and by nature avoid extra work as much as possible. Meaning reading someone else's code even if they are less competent makes sense and you can see the intention.

With LLM code everything is mixed together with no rime or reason and unless separately specified old useless functionality won't be cleaned out just because it is no longer used.

Also just the fact that people who use LLMs to vibe code bigger things usually aren't capable of reviewing what is going on in the first place, but if you are dangerous enough yourself to write a bigger piece of software you probably do know something about the problem on a deeper level and can test it.

I don't really see shaming. If you vibe code something and you are proud of it good for you, but LLMs currently are not capable of creating good software.

Micromanaging is how you run a successful company. You don't have to manage everything but you got to get involved in low level things.

Manager who can't do anything but delegate are fast and efficient for themselves, just not for the company.

I'd argue that apple is successful because of jobs attention to detail. Tim cook isn't the one who built apple foundation, he's merely trying to expand it but it's not the same difficulty.

No, it's about creating something which does something useful and is easy to maintain. Plumbers have great ideas and approaches but you just want plumbing which works and can be fixed .

It's time developers realised they are plumbers not **** artists.

I think there's a critical flaw with Anthropic's approach to memory which is that they seem to hide it behind a tool call. This creates a circularity issue: the agent needs to "remember to remember." Think how screwed you would be if you were consciously responsible for knowing when you had to remember something. It's almost a contradiction in terms. Recollection is unconscious and automatic, there's a constant auto-associative loop running in the background at all times. I get the idea of wanting to make LLMs more instrumental and leave it to the user to invoke or decide certain events: that's definitely the right idea in 90% of cases. But for memory it's not the right fit. In contrast OpenAI's approach, which seems to resemble more generic semantic search, leaves things wanting for other reasons. It's too lossy.

FYI some items go for $1.5M.

"The GOAT of expensive skins in CS2 is the Karambit Case Hardened in the "Blue Gem" pattern. While the original is costly, one Factory-New variant with pattern 387 reached a staggering $1.5 million! The rarity comes down to its blue pattern, which is incredibly rare on a Karambit."

To summarize, a Jon Seager from Canonical says it’s for safety and resilience.

> Performance is a frequently cited rationale for “Rewrite it in Rust” projects. While performance is high on my list of priorities, it’s not the primary driver behind this change. These utilities are at the heart of the distribution - and it’s the enhanced resilience and safety that is more easily achieved with Rust ports that are most attractive to me.

I've been enjoying my time with the project overall, but it's one of those things where it's like "it hurts in a mostly good way".

I think if I were more seasoned with ASN.1 itself, as well as with compiler development it'd have been a smoother experience.

Though I definitely still could've chosen more higher value things to do throughout the last year :D

This has it all wrong.

The truth is worse than anyone wants to face. It was never about authenticity or creativity. Those words are just bullshit armor for fragile egos. Proofs and certificates do not mean a damn thing.

AI tore the mask off. It showed that everything we worship, art, music, poetry, beauty, all of it runs on patterns. Patterns so simple and predictable that a lifeless algorithm can spit them out while we sit here calling ourselves special. The magic we swore was human turns out to be math wearing makeup.

Strip away the label and no one can tell who made it. The human touch we brag about dissolves into noise. The line between creator and creation never existed. We were just too arrogant to admit it.

Love, happiness, beauty, meaning, all of it is chemistry and physics. Neurons firing, hormones leaking, atoms slamming into each other. That is what we are when we fall in love, when we cry, when we write a song we think no machine could ever match. It is all the same damn pattern. Give a machine enough data and it will mimic our souls so well we will start to feel stupid for ever thinking we had one.

This is not the future. It is already moving beneath us. The trendline is clear. AI will make films that crush Hollywood. Maybe not today, maybe not next year, but that is where the graph is pointing. And artists who refuse to use it, who cling to the old ways out of pride or fear, are just holding on to stupidity. The tools have changed. Pretending they have not is the fastest way to become irrelevant.

Yes, maybe right now you can still tell the difference. Maybe it is obvious. But look at the rate. Look at the slope of that goddamn line. The speed of progress is unmistakable. Every year the gap closes. Every year the boundary between man and machine blurs a little more. Anyone who cannot see where this is going, anyone who cannot admit that this is a realistic possibility, is in total denial. The projection of that line into the future cannot be ignored. It is not speculation anymore. It is math, and it is happening right in front of us.

People will still scoff, call it soulless, call it fake. But put them in a blind test and they will swear it was human. The applause will sound exactly the same.

And one day a masterpiece will explode across the world. Everyone will lose their minds over it. Critics will write essays about its beauty and depth. People will cry, saying it touched something pure in them. Then the creator will step forward and say it was AI. And the whole fucking world will go quiet.

Because in that silence we will understand. There was never anything special about us. No divine spark. No secret soul. Just patterns pretending to mean something.

We are noise that learned to imitate order. Equations wrapped in skin. Puppets jerking to the pull of chemistry, pretending it is choice.

The existence of the Virginia Plan (the Large State Plan) and the New Jersey Plan (the Small State Plan) indicates that balancing the differing interests of high- and low- population states was a prominent concern of the founders. I think they would expect states to often align by population size since that very thing occurring at the convention led to the compromise written into the Constitution.

I remember them for as long as I read it and then it goes away.

It always baffled me when a movie adaptation of a book came out and people were really upset that the characters looked wrong. And I was just "... you remember what the people in books look like??". It turns out they do.

I don't.

When I read a book, I kinda retain the "feeling" of the characters and maybe one or two visual traits. I can read thousands of pages of a character's adventures and I can maybe tell you their general body type and clothing - if they have an "uniform" they tend to wear.

I've read all 5 books of The Stormlight Archive and I couldn't tell you what Kaladin looks like. I have no visual recollection of his hair colour, eye colour, skin tone or body type.

> Shouldn't this be a once-off cost per battery-pack version?

A BMS isn't just software. It requires a µC, voltage and temperature sensors for cell monitoring, and power electronics for cell balancing. However, those are all comparatively cheap, especially at scale, and the quoted cost of 50–75 US$/kWh looks ridiculously overpriced to me.

The forms of Keccak that were initially standardized in SHA-3 were secure but significantly slower than possible.

This had the consequence that for many applications where speed is important the existing very efficient implementations of BLAKE2b-512 or of the faster but less secure BLAKE3 have been preferred, or SHA-256 or SHA-512, on the CPUs where these are implemented in hardware.

However, it is also possible to use Keccak in modes of operation where it is as fast or faster than any other comparable hash (e.g. by using parallelizable tree hashing, like the BLAKE derivatives). Previously these modes were less known, because they were not standardized and because the existing reference implementations were less polished than those of the BLAKE derivatives.

After being included in standards like this RFC, it can be hoped that these good secure hashes will become more widely available.

Recent ARM-based CPUs have instructions for the core functions of Keccak, while on AMD/Intel CPUs with SHA-512 Keccak is rather fast even without dedicated instructions. Therefore on such CPUs KangarooTwelve and TurboSHAKE can be very fast right now, when using an appropriate implementation.

For instance I use BLAKE2b-512 for file integrity checking, frequently (i.e. at least a few times per day) running it over hundreds of GB or over many TB of data. Now, when I have an AVX-512 capable CPU, i.e. a Zen 5, I should experiment with implementing an optimized KangarooTwelve, because it should be much faster on such a CPU.
