Also:

> "What does it mean to be British?"

Doesn't mean much? There's Wales and Scotland right there, you go to Spain and find the catalonians, basque, gallegos. A country is very rarely a single thing, its a mix of multiple people's and trying to come up with a single storyline for it is a very modern thing.

People identify with the city and region they're most associated with, I'm Brazilian but first and foremost I'm northwestern, the culture, accent, food, customs and religion there is unlike other places in the country. I see no reason to find an answer to "what does it mean to be brazilian" because different people will have different answers for that but if I meet someone from my region we will quickly connect on our shared experiences.

They do mention it, but it’s downplayed relative to how much of a problem it can be.

In a situation where you have a lot of energy generation that would go to waste, storing it in a system with low round trip efficiency could be better than losing it.

For planned installations where the generation cost is nontrivial (like a solar install) then increasing the generation to compensate for poor battery efficiency isn’t as easy of a decision.

Given with how poorly Ukraine has been treated, why would Taiwan ever think they could easily get an emergency supply of chips for drones and planes exported from the US and past a Chinese blockade?

If Trump or someone similar is in the office I'd expect that there would be demands that the chips stay in the US to protect the country from Chinese aggression unless there is some kind of bribe.

Why is there no documented formula to convert to from this color space? A quick google and the best I could find is this Gist[0]. Searching for Oklab has a Wikipedia page[1].

I'd be interested in the specific commands/spec too, however as with all DRM techs I wouldn't be surprised if it's hidden behind NDAs.

However you can see from the parent comment:

> Success of mutual authentication enables host to access card protected area.

So it's something the memory control must make available after a handshake, and then I presume either some specific memory address or set of retrieval commands would follow.

As you mention, it also states this spec is now optional.

One thing they also mention is how incredibly cheap storage of natural gas is. https://en.wikipedia.org/wiki/Power-to-gas#Efficiency The efficiency of power to gas is not great, but it's about the same as this thermal storage method, with probably much longer lifetimes,easier transportation and more general utility (the natural gas could for example be converted to methanol using the holy grail catalyst that was in the news recently).

The power to gas is also carbon neutral, even negative depending on what you decide to do with the natural gas (if you don't burn it for power but use it for industrial chemistry, you get some sequestration out of it).

How is "needed" determined? 3 of my 4 grandparents made it around 100 years old with way, way less than what I "need" for my kids.

They did not need doctors, daycare, helmets, cars (they sat 5+ to a motorcycle), air conditioning, avocados, bedrooms, computers, etc.

> The way gradients work in OKLCH is pretty different compared to sRGB. In sRGB, gradients are calculated in red, green, and blue values, which often leads to muddy midpoints and uneven brightness.

I always understood those “muddy midpoints” as a failure to properly gamma correct the interpolation between two (s)RGB colors. Is that happening here, or is the mud coming from something else?

Two guesses: (1) Rhode Island is democratic controlled or (2) Trump will personally benefit significantly by keeping America's oil production high.

FWIW, we now have quite a few off-short windfarms in the UK. Apart from the curiosity (can you count all those little specks on the horizon), they're so far from land that they make basically no noticeable difference to anyone, other than a sizeable input to the regional electricity supply. It's about the least intrusive form of energy production you can get, maybe one of the safest, among the easiest to decommission, and doesn't waste valuable real estate on land. We need more of them, not less.

This is a blog article outlining a rough concept idea. As others have commented, many questions remain unanswered, and speculation about isolated physical properties and technical ideas is unhelpful.

For it to be worth spending more time and effort on, I would need a closed system thermodynamic calculation. The technical term for this is a "heat balance diagram". This is the first thing any technical consultant would request.

Another commenter already noted the CHIPS[1] act, which was a deliberate act to try and specifically bring fundamental high value chip manufacturing and science to the United States.

It is extremely relevant to this conversation. Regardless of whether you think China engages in a war with Taiwan, it is a crucial resource the US will want developed locally (similar to any critical resource like farming, steel, or rare earth metals).

CHIPs seemed more well thought out than simply taking control of 10% of Intel.

It's not just another round of a fight. This is part of Trump's campaign to prove he's king of the US and everyone in the country has to do what he wants unless they pay him to do what they want. You need to completely reject the idea that Trump is a continuation of broad societal trends, or you're going to wake up one day to find that you're being arrested for calling him a locust.

So funny you mention it cause I was on vacations in Spain few weeks ago. They are the definition of "I will avoid AI at all costs". It seems we are living in 2 parallel universes. All the Spanish I met don´t know, don´t use and don´t care about AI. I have been so busy but Linux version is coming soon, it is very time demanding. And eventually I have to upgrade to a desktop PC for better performance.

I use a non standard port and have not had an unknown IP hit it in over 25 years. It's not a security feature for me, I use that to avoid noise.

My public SFTP servers are still on port 22 and but block a lot of SSH bots by giving them a long "versionaddendum" /etc/ssh/sshd_config as most of them choke on it. Mine is 720 characters long. Older SSH clients also choke on this so test it first if going this route. Some botters will go out of their way to block me instead so their bots don't hang. One will still see the bots in their logs, but there will be far less messages and far fewer attempts to log in as they will be broken, sticky and confused. Be sure to add offensive words in versionaddendum for the sites that log SSH banners and display them on their web pages like shodan.io.

They also tend to buy Linux from someone, often MontaVista last I did some Googling long time ago...

The fundamental problem, I think, is that FOSS didn't really take off in Japan the way it did in US/EU, for some reason. There are tons of code-literate engineers but way less who would be sympathetic with developer community building, code sharing, licensing discussions, etc., that are more common in communities from US/EU.

In an ideal world the rclone special remote would support git-annex' importtree feature. Then you could periodically run `git annex import <branch>:<subdir> --from <sharepoint/dropbox-remote>` to "pull" from those remotes (it is not really a pull as you aren't fetching version-controlled data from those remotes, rather you are importing from a non-version-controlled source and record the result as a new revision).

Unfortunately this is not (yet?) supported I think. But you could also just do something like this: `rclone copy/sync <sharepoint/dropbox-remote>: ./<local-directory> && git annex add ./<local-directory> && git commit -m <message>`.

The Mafia does actually provide real waste-management services, also in Italy at large scale as far as I know.

They do engage in racketeering to ensure that they own all the contracts in a certain region, and compete for territory, but they do often actually go and collect the waste, it's not just a front. And I think they did in the Sopranos too, although it was not explicitly depicted as far as I remember, just off-hand references.

The illegal part is in how they get rid of it. Often they take on high-value contracts for toxic waste products that are complex to handle in a compliant manner, and they just dump it wherever.

I am implementing oauth right now, along with oidc. I must say that for such a simple concept, getting to the facts that help me to actually implement it is insanely hard. I have no idea why but everywhere i look it just seems like it only scratches the surface and you get no tangible information that you can use to actually implement it in code. I ended up mostly browsing the specs and grok was insanely helpful to explain meaning of various things where information was lacking or buried deep in documentation/specifications. I would say this was the first time where i actually appreciated these new "AIs", which i don't use at all.

It only takes one tiny vibe-coded insecure extension to a pre-existing codebase (that might have been good secure code), to turn the whole thing into a catastrophe.

It's basically the same as in other parts of IT security: It only takes one lost root password, one exploited software/device/oversight, one slip, to let an attacker in (yes, defense-in-depth architecture might help, but nonetheless, every long exploit-chain starts with the first tiny crack in the armor).
by CodingJeebus | 2025-08-25 13:33:40+00:00
This is an absolutely huge deal. It doesn't matter how small the scope of the change is, they thought it was a good idea to apply mandatory AI post-processing to user content without consent or acknowledgement.

Secret experiments are never meant to be little one-offs, they're always carried out with the goal of executing a larger vision. If they cared about user input, they'd make this a configurable setting.

10ft below ground is enough to take advantage of geothermal heat. You don't have to go "very far" to reach warmer soil in winter because the soil PLUS the snow on top is pretty much just insulating the deeper ground from the cold air.

Start getting into permafrost though where the cold is more constant and that cold layer gets deeper.
Show HN: Spart – A Rust library for fast spatial search with Python bindings
by habedi0 | 2025-08-25 13:33:49+00:00
Hi everyone,

I've made an open-source library for fast spatial search in Rust.

It's called Spart, and it currently provides the following features:

- Five tree implementations: Quadtree, Octree, Kd-tree, R-tree, and R*-tree

- Python bindings (`pyspart` on PyPI)

- Fast k-nearest neighbor (kNN) and radius search

- Bulk data loading for efficient tree construction

Project's GitHub repo: https://github.com/habedi/spart

More efficient, but much more expensive. I'm sick of people handwaving $100 per kWh. That is two orders of magnitude off where it needs to be to do anything more than virtue signal.

Meanwhile multiple grids are now paying renewable to curtail, because guess what, the variability is correlated (it's the exact same damn mathematics we used to fuck up the entire global economy in 2008, which is why I'm so surprised people are handwaving that too, but whatever). If you want to minimise cost without relying on gas to save you on dark still days, you want a cheap use for the surplus, round-trip be damned.

(malicious) Bot writers have exactly zero concern for robots.txt. Most bots are malicious. Most bots don't set most of the TCP/IP flags. Their only concern is speed. I block about 99% of port scanning bots by simply dropping any TCP SYN packet that is missing MSS or uses a strange value. The most popular port scanning tool is masscan which does not set MSS and some of the malicious user-agents also set some odd MSS values if they even set it at all.

-A PREROUTING -i eth0 -p tcp -m tcp -d $INTERNET_IP --syn -m tcpmss ! --mss 1280:1460 -j DROP

Example rule from the netfilter raw table. This will not help against headless chrome.

The reason this is useful is that many bots first scan for port 443 then try to enumerate it. The bots that look up domain names to scan will still try and many of those come from new certs being created in LetsEncrypt. That is one of the reasons I use the DNS method, get a wildcard and sit on it for a while.

Another thing that helps is setting a default host in ones load balancer or web server that serves up a default simple static page served from a ram disk that say something like, "It Worked!" and disable logging for that default site. In HAProxy one should look up the option "strict-sni". Very old API clients can get blocked if they do not support SNI but along that line most bots are really old unsupported code that the botter could not update if their life depended on it.

It's been weeks now that I'm getting SPAM from google.com/googlemail.com.

Somehow they can email $myusername@google.com or $myusername@googlemail.com and their mail daemon replies back to my actual gmail.com with the spammer's email content. Because these emails originate from Google's own servers, they bypass spam filters and land directly in my inbox every time.

> Directives like this from Beijing indicate how challenging it is for central governments... even the CPC, to fully control the behaviour of private sector companies.

They can fully control them, alright, but they aren't stupid - full control of behavior doesn't mean full control of results.

> As the US vs China competition unfolds at state level, the State vs Corp conflict within both countries will [be] an important below-the-surface theme.

In the US, there's no conflict and hasn't been for a while. The corp counter-revolution in China fizzled a few years ago, thus the conflict there was extinguished too. That explains a lot, including the sanctions that force China to build local chip capacity.

There's little below the surface, hidden in plain sight - yes.

The average Brit doesn't want foreign entities pushing porn and self harm / pro suicide stuff to their kids. Can you perhaps see the difference there?

I notice most of the outrage in HN is from foreign entities wanting freedom to push whatever. The Brits are ok telling JD Vance et all chill.

That's the underlying point though: spending time dealing with Linux driver issues just isn't as prevalent as it was, certainly on the wide range of well-supported machines (like Thinkpads). Hell, I'm on a Macbook running NixOS unstable via Asahi and I don't spend any time dealing with driver issues thanks to the unbelievable collective effort of hundreds of projects. Yes, the issue is still present and worse than Windows, but that would have to be part of the conversation around switching--"Hey, Aunt Jennifer, we can get you off the Windows weirdness, but it might be time to pick up a new laptop to do it."

As to the first issue, you're right about installed base of Windows helpers, but my assumption is that a large proportion of folks would be switching because a family member was helping them make the move.

Pure, unfiltered anecdata, but my kid uses Linux at home and he doesn't experience even 5% of the bizarre issues he tells me about on the district Windows computers (which are, granted, about 8,000 years old).

Interesting because I've been thinking about mechanical energy storage recently. I feel like these concepts hold a lot of promise on a small scale, per-house; coupled with solar panels. Although mechanical batteries they are not as efficient as electric batteries (and lose some energy), they can be both cheap to make and durable; these characteristics are much more important than raw efficiency when dealing with a single house.
by ksec | 2025-08-25 13:36:06+00:00
Agree. I think all the discussions often missed the main problem. Apple App Store holds far too much power, and they alone decides letting or stopping other business. All Banks, Finance, Ecommerce, Retail need to kowtow to Apple or Google for access. And that is not the power and responsibility you want to hold.

People argue you have Website too. But Website does not provide the same level of experience and is at disadvantage compared to Apps.

I have long argued Apple should have given up this power since 2013 / 2014. And Apple should split Games to Game Store, that keeps their 30% cut and would have kept at least 70 - 80% of their current App Store revenue.

For what ever reason last time I said this in 2018 and 2020 I was devoted to oblivion on HN.

We have the same issue in France as well.

Why won't the government do something is the refrain that everyone including opposing parties are saying. God forbid anyone should take initiative on anything.

And the state keeps on expanding year after year. I cannot remember the last time someone did not promise to shrink the state/government and once elected did a complete 180. It's bonkers.

Do scientists think fast radio bursts come from neutron stars or magnetars? And with new tools like CHIME and VLBI, can we figure out if some of these bursts actually repeat?

I'm still fascinated at the prospect of these "star quakes" or magnetic flares that emerge from these stars. I guess these fields would weaken over time, but does it really maintain it's mass, just lose rotation speed or something?

Generic American English pronounces the 'h' in hospital, hero, heroine, but not hour.

Same is true for RP English.

Therefore, for both accents/dialects, the correct phrases are "a hotel", "a hero", "a heroine", and "an hour".

Cockney, West Country, and a few other English accents "h drop" and would use "an 'our", "an 'otel", etc.

I think the main driving force is it’s a way to monetize an LLM. If the LLM is doing the buying then a “buyer fee” can be tacked on to the purchase and paid to the LLM provider. That is probably an easier sell than an ongoing monthly subscription.

Also, sellers can offer a payment to the LLM provider to favor their products over competitors.

Solar prices are coming down quite fast, I don't think a factor of two is going to be a killer here if the storage is cheap and long-lasting enough. Some people are already considering over-provisioning solar panels relative to available transformers/grid connections so that they can maintain output on cloudier days.

Contrariwise, there was a widespread belief that we were at significant risk of cascading computer failures that could take out critical infrastructure when the year rolled over from 1999 to 2000. When midnight struck on January 1, 2000, nothing much happened, and skeptics said "See? It was no big deal. Turns out there was nothing to worry about after all." But actually, software engineers had been working since years before to update those critical systems since years before and their efforts paid off, making Y2K seem like a non-event.

Maybe we haven't observed Nazism rise again in Germany because the policies against Nazi expression, first implemented by the Allied occupying forces immediately after WWII, worked so well.

Hi HN, I built this rails CRUD app because I needed a YNAB for cars and I kinda kept abandoning every spreadsheet for my project cars because they get so boring and I hate working with spreadsheets logic...

It's not the smartest nor the most impresive app that's been displayed here, but it works really well for my use case and I thought of sharing it with a wider audience to get some feedback on it. Have a play on https://wrenchwise.app

The only thing I remember is from the book Showstopper

https://retrocomputing.stackexchange.com/questions/14150/how...

[Cutler] expressed his low opinion of the Unix process input/output model by reciting "Get a byte, get a byte, get a byte byte byte" to the tune of the finale of Rossini's William Tell Overture.
