Yes, but that 24% increase in Europe is partly due to increase in vehicle size. Vehicle size is increasing over time in Europe, and the average EV is newer.

Also, cars designed as pure EV's are a lot lighter than EV's built on an ICE chassis.

A Telsa 3 is about 2% heavier than a BMW 3 whereas a Ford Lightning is 20% heavier than the comparable F-150.

In Canada, diesel fuel is priced around mid-grade gasoline (89). So it's slightly more expensive than regular, but slightly cheaper than premium (91/93).

Based on this, I've always thought of diesel as "more expensive", like you better get 15% more power/miles out of it if it's going to cost more! However, I suspect that most people purchasing diesel vehicles have as their other choice a car that would slurp premium, so for those buyers perhaps diesel is still a discount, even in Canada.

How bad it is exactly? Resistive heating sounds cursed, when the houses are (I guess) not the fancy European newbuild.

I'm looking at something like 1000 kWh on a heat pump a year in a mild weather, where kWh is around 0.30 eurocents. I don't however own the pump, energy company leases it to me, so I pay about 150 a month the whole year (cold months are about 4 GJ, but it totals to 18-ish in a year). Then there is another 10-30 a month for normal in-house electricity consumption.

When I had actual district heating (powered by gas, when the gas was expensive af) and the house was "leakier", I looked at something like 50ish GJ a year and paid close to 350.

> Reasoning that if he's not good it would show up in patients thinking he's bad, and not feeling any better.

This is like a questionnaire on how much stronger you feel after working out at a gym: you often don't, you feel tired.

Both gym and talking therapy (when done correctly) will push you slightly out of your comfort zone, and aim to let you safely deal with moderate amounts of something that you find really hard. So as to expand your capabilities.

"I feel good" immediately after is utterly the wrong metric.

Being more capable / feeling better some time later is the more reliable indicator, like progress at a gym.

And also this is why an agreeable statistical word generator LLM is not the correct tool for the job.

If the part about how "most of those crates wouldn't be doing funny operations on pointers" can be verified automatically in a way that preserves safety guarantees when usize != uaddr/uptr, these crates can continue to build without transitioning to a newer edition. Otherwise, upgrading these crates is the right move. Other code targeting earlier editions of Rust would still build, they would simply need a compiler version update when depending on the newly-upgraded crates.

That limitation is already accounted for in how the title is meant to be read. The 224× compression result is specifically about the structure of intermediate activations on classification tasks. The paper makes that explicit in multiple places, including the Limitations section, where generation is identified as an entirely separate challenge.

The title reflects the strongest verified result in the domain the method currently supports, not a universal claim across all modalities. In other words, the compression result is real, but it shouldn't be interpreted as applying to generative decoding... yet.

The harm from unaccountable governments who treat their constitutions like suggestions is far greater still, though. It's not about the guns, it's about the list. If you're an American who's not outraged by Emanuel's statement -- on guns or on social media for that matter -- it's because you feel privilege that you may not actually possess.

On that subject, it's certainly a strange time to argue for government's role as the holder of a monopoly on the tools of violence, isn't it? The human consequences of this misguided philosophy ran well into eight figures in the 20th century alone.

In any case... say what you will about the US, we won't shoot you at the border for trying to leave.

In my experience, legal and tax complexities are more than sufficient to restrict the countries that we have remote workers living in.

We work globally so practical things like timezones aren't really a factor; we have plenty of experience working around them. That even goes as far as things like personal security in locations that are particularly dangerous. In my line of work that usually means risk of kidnapping. It will be a factor we take into account but wouldn't usually be decisive.

Having said that, I have been involved in setting up multiple offices in new locations. But only where we're expecting to have a significant presence over the long term. Essentially, where we can amortise the costs of legal and tax expertise.

Empromptu ($2M pre-seed): AI application builder with Self-Managing Context
by anaempromptu | 2025-12-10 16:53:02+00:00
Hey HN,

I'm Shanea, founder of Empromptu. We just raised $2M from Precursor Ventures to solve a problem I kept hitting: most AI features never make it to production.

The problem: You can prototype AI features in hours now, but getting them production-ready is still brutal. Context windows explode past 100+ documents. Accuracy drifts. Integration with existing codebases is messy. Most teams either rewrite their platform or hire specialized AI engineers.

What we built: An AI application builder that generates full-stack features (frontend, backend, models, observability) and integrates them into existing SaaS platforms. The new piece is Self-Managing Context - a graph-RAG architecture that handles 100GB+ worth of files, maintains accuracy through multi-level summarization and is designed to improve from usage over time.

Current state: 2,000+ businesses using it 98% production accuracy On-prem or cloud deployment One healthcare SaaS founder used it to add an AI-powered CRM feature without expanding their team

Happy to answer technical questions about the architecture, especially around how we're handling context management at scale. Also curious what blockers other founders have hit moving AI features to production.

Um, noise mitigation is still an issue at existing gas plants (e.g., [0-3]) and often only partially dealt with by local regulations, and this group are claiming their engine is substantially different, supersonic vs subsonic, and crossing that threshold usually involves large noise generation effects.

At least concerning Richard M. Stallman's take on this subject, this characterization is completely wrong.

RMS certainly does not consider the difference between open source and free software to be merely one of 'emphasis.' According to him they are completely different animals. Here are his words on their difference[0]:

> 'When we call software “free,” we mean it respects the users’ essential freedoms: the freedom to run it, to study and change it, and to redistribute copies with or without changes (see http://www.gnu.org/philosophy/free-sw.html). This is a matter of freedom, not price, so think of “free speech,” not “free beer.” ... Nearly all open source software is free software; the two terms describe almost the same category of software. But they stand for views based on fundamentally different values. Open source is a development methodology; free software is a social movement. For the free software movement, free soft- ware is an ethical imperative, because only free software respects the users’ freedom. By contrast, the philosophy of open source considers issues in terms of how to make software “better”—in a practical sense only. It says that non-free software is a suboptimal solution. For the free software movement, however, non-free software [including non-free open source software] is a social problem, and moving to free software is the solution.'

[emphasis and square brackets mine]

It's not that RMS 'prefers the term "free software" over "open source"' but that he prefer software be free instead of non-free. The source being open is just an incomplete precondition for being free.

I'm curious how congestion pricing became a national issue. The strength of conviction people have about this policy–almost either way, but certainly among those against–seems to scale with distance from the city.

Nobody in Idaho gets uppity about New Jersey's tolls. But they have strong, knowledge-free, almost identity-defining opinions about congestion charges.

Is it because it's a policy that's worked in Europe and Asia and is thus seen as foreign? Or because it's New York doing it, so it's branded as a tax, versus market-rate access or whatever we'd be calling it if this were done in Miami?

I replaced my Kindle (2nd gen, 2009 vintage) with a Boox Go 7 (non color), can flip pages with the two side buttons, it’s very nice hardware and the software doesn’t get in the way.

Amazon doesn’t care about my super old kindle so I decided to also not care and just moved my collection of purchased books over to the Boox (using Calibre).

Seems paradoxical.

If I'm not allowed to have guns, then I am physically unsafe, because someone from government will use violence against me if they both discover it and have the ability to do something about it. I wouldn't feel safe anywhere violence is used for malum prohibitum 'crimes.' In fact I don't feel safe basically anywhere a government exists because they all do this; this is part the reason why I live in a rural area with basically no government services, no police, no public utilities or anything like that with involvement by the state beyond the bare minimum possible in the USA.

Your proposition also relies on the place itself not changing, and my and my offsprings atrophying their practice of skills of self defense and therefore not needing them when moving elsewhere. But sure if you had a magic wand and could trade 'no guns' for anyone for world peace, I'd take it.

I'd say, that even more than pointer sizes, the idea that a pointer is just a number really needs to die, and is in no way a forward looking decision expected of a modern language.

Pointers should at no point be converted into numbers and back as that trips up many assumptions (special runtimes, static/dynamic analysis tools, compiler optimizations).

Additionally, I would make it a priority that writing FFIs should be as easy as possible, and requires as little human deliberation as possible. Even if Rust is safe, its safety can only be assumed as long as the underlying external code upholds the invariants.

Which is a huge risk factor for Rust, especially in today's context of the Linux kernel. If I have an object created/handled by external native code, how do I make sure that it respects Rust's lifetime/aliasing rules?

What's the exact list of rules my C code must conform to?

Are there any static analysis/fuzzing tools that can verify that my code is indeed compliant?

Does Qwen3-Omni support real-time conversation like GPT-4o? Looking at their documentation it doesn't seem like it does.

Are there any open weight models that do? Not talking about speech to text -> LLM -> text to speech btw I mean a real voice <-> language model.

edit:

It does support real-time conversation! Has anybody here gotten that to work on local hardware? I'm particularly curious if anybody has run it with a non-nvidia setup.

Stock market crash? I believe less and less a 1929 style crash is possible. Tesla, Uber, hell, look at GameStop still... The market is rigged. The US and the upper class needs numbers go up, the numbers will go up.

The only way an adjustment to such stock prices would come is if US power and dollar vanes. There is a chance now this will happen, but I guess it will still take a long time.

> Now, imagine where the highest concentration of bugs will be. And how many bugs there will be elsewhere.

You're doing it again!

Doesn't matter where the majority of bugs will be. If you avoid the minority it's still an improvement.

Also, Rust safety is not related at all to bugs. You seem to have a misunderstanding of what Rust is or what safe Rust provides.

(Also, I'd challenge the rest of your assumptions, but that's another story.)

My only experience is BMW EV, but my i4 aggressively prioritizes regeneration over using the brakes. It even has an energy meter that shows negative/positive energy flow. The positive flow is blue until the actual brakes engage where it changes to black. And this is in two pedal mode, one pedal driving is even more aggressive about regen.

I would not doubt I use my breaks 1/20th of the amount that our X5 or Silverado use theirs.

Money can buy quality of life, and people earning 100-150k in USA per person in household do confirm this. And this purchasing ability is not linear, because of the fixed costs for many good and services. Previously many countries with low salaries had corresponding low cost of life (and cost of quality of life), but today the costs are rising faster than salaries everywhere across the globe, so the biggest winners are people who earn more in absolute values, hence rich Americans.
by catapart | 2025-12-10 16:57:10+00:00
Right on. Thanks for the consideration!

I really appreciate you walking through that; it's an eye-opener! It seems like you not only deal with a considerable amount of five-minute-or-greater videos, but much higher quality than I was expecting, too.

I also like the idea of user-transcoding because, honestly, I think it's better for everyone? I would love if every place I uploaded video or audio content offered an option to "include lower-quality variants" or something. Broadly, it's my product; I should have the final say on (and take responsibility for) the end result. And for high-quality stuff, the people who make it tend to have systems equipped to do that better anyway. So they could probably get faster transcoding times by using their own systems rather than letting the server do it. Seems like a win-win, even outside of the obvious benefits of "make a whole lot of computers do only the work they each need done, instead of making a few computers do the work that everyone needs done". With the only slight downside of the "average user" having some extra options that they don't understand which cause them to use it wrong and then everyone hates your product. Yay, app development.

I did a pretty low rigor test and just pulled up one of those 4K videos with the swirling ink in Firefox on my M1 Mac and it seemed to load just as fast. The only difference was that it didn't autoplay the video (because I'm logged out I think) but I clicked it as the page loaded and it played instantly.

I don't doubt at all that Google hobbles their sites on Firefox but at least on my machine they aren't doing a great job of it

Please explain the ACA subsidies and SNAP benefit cuts to rural republican voters who will still vote for this then. Are these people going to change their vote? Again, likely not. Their mental model and their identity is rigid (along with a bit of in group and tribalism) and they will very likely vote this way to the very end. You can live a better life by leaving while waiting for these voters to age out, because you cannot change their mind or their vote. If you stay, you will be exposed to governance outcomes from their votes.

You can think of it as the grey rock method in a political and expat context. You don't engage, doing so would be of no value; you just ignore and leave. Life is short, optimize accordingly.

Show HN: Vocation: AI Career Coach for Mid-Career Transitions
by cliffcmaxwell | 2025-12-10 16:57:48+00:00
We've taken a decade of research and over 1,000 interviews to build a career coach that helps mid-career professionals figure out their next move.

My own career is a winding one - from CPU design, to education research, to supporting Clay Christensen ('disruptive innovation'), and later venture capital.

When you want work to mean something, but you enjoy a lot of things, it's hard to navigate next steps. Vocation guides you through that process of discovery.

There are tons of AI-slop career support, resume prompts, etc. It's all designed with your resume or a job in mind.

Vocation is designed to help you figure out yourself first. To define what progress really means. And what your unique context says about what you need.

We're trying to help you find the RIGHT job, not just any job.

Would love your feedback.

For me it was a factor to some degree. I am not a firearm collector. For me it was knowing that I was moving from a state that hates firearms and wants to justify law enforcement budgets by punishing anyone that defends themselves to a state that not only has very few restrictions on firearms and ammo but also actively and legally supports people defending themselves and their neighbors. That was just one of many factors however. No state income tax was also a big plus for me personally.

Is that because of gridlock or because of the higher energies?

This is quite interesting: it's easy to blame the use of LLM to find the interface, but really this is a matter of needing to understand the COM calling conventions in order to interact with it.

I found the interface and a C++ sample in about two minutes of GitHub searching:

https://github.com/microsoft/SampleNativeCOMAddin/blob/5512e...

https://github.com/microsoft/SampleNativeCOMAddin/blob/5512e...

but I don't actually think this would have helped the Rust implementation; the authors already knew they wanted a BSTR and a BSTR*, they just didn't understand the COM conventions for BSTR ownership.

I've yet to see AI-generated video which _doesn't_ have this sort of problem; everything moves unnaturally and physics doesn't work properly. Unless it can shed that nightmarish quality, it's DOA, and it's not at all clear that it _can_, via current techniques.

I would actually wonder if AI generation of 3d models and movement instructions, coupled with a conventional physics engine, might be more viable, though it would obviously rule out attempts at photorealistic stuff.

Not a bad choice. I'd probably pick Greenland out of the European (Denmark I think?) jurisdiction territory. You can buy bolt action rifles like a hammer at hardware store. They are looser than the USA on that point, though I didn't initially include them because they are stricter on most everything else. But open carrying a rifle probably isn't frowned upon in Greenland, so it might not matter that you can't carry a handgun.

I've _never_ read an ebook w/o finding at least one typo --- and that includes _Dune_ which I didn't download until after the ebook had been out for over a decade ("pogrom" was mis-spelled as "program" and there was an error in formatting in the glossary) --- but this happens w/ print books as well, my second printing of Tolkien's _The Fall of Arthur_ had a typo (which when reported, I was promised would be fixed in subsequent printings).

The worst was the free copy of Heinlein's _Space Cadet_ I got from Sony on my PRS-505 because I was browsing their store on a day when they offered a $10 credit --- it was so riddled w/ typos that I had to get a print copy from the library to determine what some of them were.... the hilarious thing is that that "purchase" made me eligible for the ebook price fixing settlement, really should have kept and framed that check.

A lot of these automatic marshalling systems (in this case, windows-rs) can be annoyingly unintuitive or opaque in how they handle subtler details of memory ownership, character sets, how to allocate and free objects, etc. And then it's made worse by documentation that only gives the output of one marshalling system (in this case, .NET) that's different from the one you're using, so you have to translate it both backwards and forwards. I guess this is mainly a consequence of COM trying to be all things to all people, being used by both unmanaged and managed code.
