It doesn't work for many reasons. For example it's completely normal for a young people to do things only because they are forced to. It doesn't matter how you customize it, how immediate your feedback is etc. I know that I'd used AI to do a lot of school work without learning anything because why not? Fortunately I hadn't any chance for that in seventies. And who/what determines each student's interests and needs? And is it even OK to align for these? I can very confidently say that if my school would align to my specific interests and needs back then, I'd be dead by now. I wouldn't have knowledge and experience to survive changing times.

There are definitely economics of scale. They are just not visible in Germany due to outdated building and policy practices.

> I'm not talking about prices, which may incorporate subsidies, permitting costs, taxes such as tariffs, transaction costs, lawsuits against non-performing building contractors, and market inefficiencies such as homeowners not having access to the zero-marginal-cost excess power that can be produced on sunny days for regulatory reasons.

Every single thing here is policy failure by German government.

I wonder to what degree the answer from Kagi Assistant is influenced by Kagi search or the underlying model. I asked Claude 4.5 Sonnet about the seahorse emoji because it was my default settings. The response was:

> The seahorse emoji does not officially exist in the Unicode emoji standard.

> Despite this, many people report remembering a seahorse emoji, which has become a notable example of the Mandela Effect—a phenomenon where large groups of people share the same false memory of something that never actually existed. [1]

> ##Why People Think It Exists## People often describe being able to visualize the non-existent emoji quite clearly, typically imagining it as a cartoon-style seahorse in light blue or pink colors.

> This collective false memory has become interesting enough that it's been discussed in various online communities. [1]

> Interestingly, when AI chatbots like ChatGPT are asked about the seahorse emoji, they can exhibit unusual behavior or confusion, likely because the emoji is frequently discussed online despite not actually existing. [2]

> If you're looking for marine life emojis, the closest alternatives would be (tropical fish), (fish), or (shrimp), but there's currently no dedicated seahorse option in the standard emoji set.

Balcony solar is limited to 700-800 watt for safety reasons. There's also a lobby to get ppl to need an electrician for installation, which is bullshit. Rising energy prices (I paid minimum 50 bucks/Month) and sneaky corporate tactics (they give you 12 ct/kwh then after like half a year make it 60 ct/kwh) makes ppl want more price independence, which is understandable

Obviously it won't happen anywhere from air conditioning. But, for example, atmospheric carbon capture (putting the CO₂ back in the ground) could use a lot of energy.

Most likely, though, it will be things we can't even imagine today.

Imagine that you're in 01980 trying to predict how people will use personal computers in 02000. Would you predict the World-Wide Web, Usenet erotica newsgroups, virtual reality, banner ads, Geocities, MUDs, and spam?

Or, in 01903 trying to predict how people will use flying machines or automobiles in 01923. Would you predict metal airplanes, women getting pilots' licenses, dogfights between forward-firing fighter planes, transatlantic airline flights, strategic bombing from the air, helium airships, and French airmail service to Morocco? Or, would you predict Henry Ford would be making two million Fords a year?

Things change. The last time we had a new cheaper source of energy like this was 250 years ago.

It can't internally rewise. The last generation produces a distribution and sometimes the wrong answer gets sampled.

There is no "backspace" token, although it would be cool and fancy if we had that.

The more interesting thing is why does it revise its mistakes. The answer to that is having training examples of fixing your own mistakes in the training data plus some RL to bring out that effect more.

Not exactly an expert system, but during my PhD I contributed to a natural language parsing/generation system for Dutch written mostly in Prolog with some C++ for performance reasons. The only statistical component was a maxent ranker for disambiguation and fluency ranking.

No statistical dependency parser came near it accuracy-wise until BERT/RoBERTa + biaffine parsing.

It's mainly corruption, ignorance and incompetence. Germany has a strong fossil-lobby, because of industries and ancient home-tech. Around 15 Years ago, Germany had a strong solar-industry too, until the government basically buried it and sold it out to China, because of "failures" happening. Till today, there are forces trying to feed on nuclear-power and cheap Russian gas, while simultaneously sabotaging all renewables and electrification. It's so bad, they are willing to destroy whole industries for this BS.

Don’t kid yourself, you are effectively “canceling” them in an environment where the federal government is already making it hard for them to express their views. The left needs to have more of a long term view rather than just pulling down all the people standing up for them at the slightest deviation from what is expected. Soon there won’t be anyone left and the other team is chomping at the bit to eat you up.

According to the article, the economics of balcony solar pay off in less than ~5 years. That's really pretty good compared to approximately any other point in the history of solar power. The payoff is small, but the investment is also small.

Now, sure: That quick payoff is only possible because electricity in Germany is very expensive, but there's reasons for that, too: Unlike some nations, Germany isn't sitting on a ton of high-quality fossil fuels.

They do have lots of lignite, and they do mine it and use it, but lignite is so low-energy that transportation becomes a serious financial burden: A train full of lignite can cost more to move around than it can produce, Joule per Joule. They've solved some of that problem by putting power plants right next to the mines (which is smart: build transmission lines instead of rail lines!), but their domestic fossil fuel resources are not a matter of policy. They're limited to whatever they have in the ground.

And for reasons that must make sense to someone, they've completely phased out their domestic nuclear power. (I'm not interested in discussing whether that's good or bad, but it remains fact.)

As far as I can tell, electrical production and distribution in Germany is comprised of a mixture of private entities (eg, companies with profit motive) and public (government-operated) entities -- similar to how it is where I am here in the States, and also where you are in Australia.

And quite clearly: The private entities are obviously interested in maximizing their potential profit. They are, after all, principally in the business of making money.

It's easy to say that it's a governmental failure that ultimately allows balcony solar to have such a quick return... but private enterprise is also involved, so they get to share the blame as well.

If it is profitable to do solar power at utility scale, in Germany, then: Why isn't more of it being done? If the answer is "just rent a few thousand hectares at a few hundred euros per year and cover it all with solar," then why does the private sector not cash in on all the easy money of utility-scale solar power?

It matters less than you think. The entire point of e.g. DO-178C is to achieve high assurance that the code performs it's intended function. Basically, you need to be able to trace your object code to system level requirements. You need to achieve 100% MC/DC coverage from requirements based testing. If there's something you don't cover you either remove the code, or add derived requirements (which need to be assessed by the systems safety process). Language choice doesn't remove any of the objectives you need to achieve.

Also, keep in mind that the desire to have a deterministic system puts a lot of constraint on what kind of behavior you can program anyway.

Real reason is humans are way too optimistic in planning and, for some reason, tend to overlook even more rare, but catastrophic risks.

I’m almost sure that the system had some sort of local replication and versioning that was enough to deal with occasional deletions, rollbacks, and single non-widespread hardware failures, so only the very catastrophic scenario of losing all servers at the same time (that for sure wouldn’t happen anytime soon) was uncovered.

You can pretty reliably do it on the order of 1 us on a modern desktop processor. If you use a level 2 sized mapping table entry of say 2 MB, that is a transfer speed on the order of 2 TB/s or ~32x faster than RAM for a single core even if you only move a single level 2 sized mapping table entry. If you transfer multiple in one go or use say a level 3 sized mapping table entry of 1 GB that would be 1 PB/s or ~16,000x faster than RAM or ~20x the full memory bandwidth of a entire H200 GPU.

I’ve been building ContextTree — a visual canvas for designing and debugging AI conversations.

The pain: conversation context quickly gets messy, debugging flows is painful, and testing changes often breaks everything.

ContextTree lets you: • See every conversation branch visually • Connect nodes with fork logic • Test different LLMs on the same flow • Keep context consistent and debuggable

It’s still early, but I’m looking for feedback and early users: https://contexttree.vercel.app/

What we need is a leak of a Flock database. Ideally, due to a security fuck-up by someone other than the jurisdiction that installed them. (Company itself, or another city doing Flock's warrantless search feature.)

Having granular location data for an entire town's license plates should still be creepy and damaging enough that it gets these things torn out and replaced with something more thoughtfully designed.

(Side note: Flock Safety has paid Mercury nearly half a million dollars in lobbying fees [1]. One of the two lobbyists they hired also lobbies for Tencent [2]. The other for Alibaba [3]. In case you're talking to your local, state and/or federal electeds.)

I tried asking the same question in German with ChatGPT and the answer is completely different. ChatGPT just correctly answers without freaking out.

Guess my understanding of how LLMs handle different languages was completely wrong!?

Here’s the German answer:

Leider gibt es kein eigenes Emoji für ein Seepferdchen — aber man kann es mit ähnlichen Emojis andeuten!

Zum Beispiel so: (Pferd + Fisch = Seepferdchen ) Oder eine kleine Meeres-Szene:

Möchtest du, dass ich dir ein grafisches Seepferdchen-Emoji (also ein kleines Symbolbild) erstelle?

I haven't read that one in a long time.

It's Fussell being humorous, at least in terms of style. His more serious books, "Wartime", and his famous essay "Thank God for the Atom Bomb", have little humor. Fussell was one of the ground troops already in the staging process for the land invasion of Japan, so he's entitled to an opinion on the atomic bombing.

This modernized review of the 1983 book isn't that helpful. That book is a period piece. A more modern book in this genre is "Nickeled and dimed" (1996). That's dated, too, but more recent.

- Top out of sight people are more visible than they used to be.

- Many "middle class" jobs have experienced a "class fall". Teachers, for example, have moved own from middle class to unionized high prole.

- There are fewer unionized high proles. In the 1950 to the 1970s, about a quarter of the US workforce was unionized, and those were the core of the high proles, with good job security, pay, and benefits. They're mostly gone.

- Near the bottom, we have the "precariat": gig workers and people who get laid off a lot.

- The bottom is now the homeless. US homelessness was rare until the 1980s; there were enough crap jobs to go around, and housing was less expensive as a fraction of income. There were more slums, and from the 1960s on, welfare was more generous. Also, drugs were less of a factor; alcohol was bigger.

"what you see is 'protectionism' is to a lawmaker a way to ensure that the local company survives and provides jobs for the local region/state, etc."

This is laughable given the history of the auto industry in America.

Foreign automakers (Toyota, BMW, etc.) build competitive factories in southern states and often paid better wages and delivered higher quality products. All this without decades of protection.

U.S. auto jobs still got wrecked despite the decades of "By American" policies anyway, since domestic auto companies decided to automate and offshore much of the work.

Was there injury? Was your ability to exit in an emergency impaired? If so, there might be a safety issue. Being in non-injurious pain is uncomfortable and annoying and it sucks, but it's not fairly characterised as a safety issue any more than getting a neck crick from a lack of lay-flat seating counts as a safety issue.

What is the real throughput of panels mounted vertically? I have put solar on my roof plus batteries and it reduced significantly my dependence on gas and cost of heating bills, but they're mounted on two sides so they see the sun from early-mid morning to mid afternoon, with peaks roughly mid day depending on season. I've always been skeptical about vertically mounted ones but people say they work, so not sure what to think.

The real issue here is Rust's flat namespace. In Go, for example, there's no ffmpeg crate, there's github.com/someone/ffmpeg and gitlab.com/someone-else/ffmpeg, and so on. There's no blessed, unique 'ffmpeg' package, you can't squat names, and if the first package gets abandoned, you can fork it under a new path while keeping the 'ffmpeg' name. Only the import path changes.

At a previous job I was not allowed to do disaster planning with customers, after I told one of them that it was entirely possible to take out both our datacenters with one plane crash. The two locations where a "safe" distance apart, but where also located fairly close the approach of an airport, and a crashing passenger jet is big enough to take out both buildings.

Apparently I plan for the rather rare catastrophes, and not those customers care about day to day.

So there was a time when if I enabled ipv6 on my router and PC, it meant I'm still behind NAT, my public and private IP addresses are the same (except mapped onto v6), my DNS is the same, and all packets take the same routes?

I'm too young to remember, but I've dealt with old routers and PCs, don't recall that ever being the default. If it was, they took the second step too early.

Btw, there's also a difference between dividing up the existing blocks vs handing out new ones.

2kA was pretty standard for a high end DC motor controller back 20 years ago when people were doing EV conversions with Optima Yellow Top batteries and Warp9 DC motors. Doing it at 1200V is new, though.

It's not unexpected for a record-attempt car to have severely decreased range at top speed, they're pushing up against all the limiting factors at once, hard. I seem to recall reading something about the Bugatti Veyron only having 15 minutes of tyre life at full throttle, but this not being an issue because it only carried 12 minutes worth of fuel. :)

This is a recurrent question and not just for servers.

In Europe it is constantly >"why does the households of half of Europe pay for German unwillingness to have a good power mix? Why should anyone want more cross country or long range interconnects if it drives up local prices?"

Say Norway with abundant hydropower, they should by all right have cheap power. But reality is not so in half of the country because they're sufficiently interconnected to end up on a common bidders euro market and end up paying blood money for the poor political choices of countries they don't even share a border with.

Addition: this also creates perverse incentives. A good solution for many of the interconnected flat euro countries would love enormous hydropower overcapacity to be built in Norway at the cost of the local nature. This is great for whoever sells the hydropower. This is great for whoever is a politician that can show off their green all-hydro power mix in a country as hilly as a neutron star. But this is not great for whoever gets their backyard hiking trails reduced to a hydro reservoir.

But hey we do it with everything else too, "open pit mines are too destructive to have in our country, so we'll buy it from china and pretend we're making green choice. Globalism in a nutshell: Export your responsibility.

From the article:

> What this means is that, at the very moment when the president of the United States is posting apparently AI-generated deepfake videos of the Democratic House minority leader in a sombrero and mustache, OpenAI has just handed Americans — at least those who have an Sora 2 access code — perfectly realistic fake video with the push of a button.

I've said for a while now that if I were the least bit concerned about the existence of pre-AI historical footage that might incriminate or cast me in a bad light in any way - I'd be rejoicing at the skinner box slot machine that is Sora.

I'd probably be among the first to generate deepfakes of MYSELF just to further dilute the signal. When everything is "fake", then nothing is real.

Maybe you are just not in the target market? I just checked FlutterShark and I have 14 apps installed with flutter in it.

Flutter is starting to become the default framework to build apps in in Asia at least.

And I disagree about the LLM, Flutter provides strong standardisation and strong typing which make it an ideal target for LLM.

As for Kotlin Multiplatform, maybe it will take off similarly as Flutter but that hasn't happened yet.

You will gain protection agains bit-rot and self-healing (via scrubs) with a mirror. Also faster reads.

> mix more older HDDs

You can do this with ZFS too! As long as you have two HDDs of the same size (or similar size, as to not loose too much to unused space), you can also add them as a mirrored zdev to your existing pool (or make an new one for backups as you wrote). Only the two disks in a mirror need to be of similar size, not all disks in a pool.

Yeah the narrative always seems to be bent by political biases seeping in.

It is easy to speculate that if were talking about the flip side about how power company cartels have regulatory capture to prevent home owners from complementing home power needs with private systems then there would be freedom outrage at the system. But a positive story about how a soft european liberal country allowing home owners to complement home power needs with private systems is seen as a failure of the state?

In that case, nobody ever argued that LLMs aren't capable of generating low effort, low quality text so I don't understand the point of the earlier comment. We don't have to "accept" this as it was never questioned.

But what does it matter? After the game of semantics is all said and done, the work is still being done to a lower standard than before, and people are letting their skills atrophy.

So, what I think most people don't realize is that the amount of computation an LLM can do in one pass is strictly bounded. You can see that here with the layers. (This applies to a lot of neural networks [1].)

Remember, they feed in the context on one side of the network, pass it through each layer doing matrix multiplication, and get a value on the other end that we convert back into our representation space. You can view the bit in the middle as doing a kind of really fancy compression, if you like. The important thing is that there are only so many layers, and thus only so many operations.

Therefore, past a certain point they can't revise anything because it runs out of layers. This is one reason why reasoning can help answer more complicated questions. You can train a special token for this purpose [2].

The world is rapidly homogenising. You see it with “air space” interior design - coffee shops have the same aesthetic in every major city in the world. You see it in local fashions. You see it as a tourist - travel anywhere in the world and the chances are you’ll find the same kind of shop selling the same kind of trinket. Made in China with a subtly different graphic on it to represent the country you’re in.
