I remember that yes, expensive operations could take a while, but the interface was much faster than my M1 Max Studio for the sole reson you actually do not have to wait for animations.

And not just for the reasons that animations were sparse, they also never blocked input, so for example if you could see where a new element would appear you could click there DURING the animation and start eg typing and no input would be lost meaning that apps you used every day and became accustomed to would just zip past at light speed because there were no do-wait do-wait pipeline.

It's actually wild that they're trying to sell lack of basic desktop features as "security features". Try explaining to an average person that when they are playing a game and want to capture a cool moment to share on Discord with their friends that by design the window server they are using will not let them do that and it's "for their own good". Like God forbid I want my computer to be actually usable. We had the same situation in the past when Wayland lacked a way to lock in the cursor within a window and it took them like 8 years to develop a "protocol" or whatever they call it. Imagine that for each basic desktop usability/UX feature, we will have to wait another decade. At that rate Linux will never have widespread adoption on desktop. Wayland sometimes feels like an active effort to sabotage Linux on desktop.

> you can build most of the control and readout circuits to work at cryogenic temps (2-4K) using slvtfets

Given the magic that happens inside high-precision control and readout boxes connected to qubits with coaxial cables, I would not equate the possibility of building one with such a control circuit ever reaching the same level of precision. I find it strange that I haven’t seen that on the agenda for QC, where instead I see that multiplexing is being used.

> The theoretical limit for this quantum computing platform is, I believe, on the order of a million qubits in a single cryostat.

What are the constraints here?

You jest, but that's how my sister gets through life, and it's always fascinated me.

She's incredibly intelligent, but more importantly she's a phenomenal social networker. She always has someone to call to ask about any question or solve any problem that comes up in life, and she's great at connecting these people with each other when they have problems of their own - so they all want to help her with whatever she needs, just to gain access to a pool of people they themselves can talk to.

What do you do with a skillset like that? I honestly don't know - something in leadership, probably, something where finding the right people and setting them to work is the most important skill of the job.

I see, thanks. FWIW I was succinct because I didn't think a comment to the effect of "I prefer to let AI do my thinking for me" merited a substantive response. I was (and still am) also genuinely curious what these 3-5 examples were. South Korean chaebols? Roman latifundia? Perhaps we'll never know

Can you replicate an algorithm just by looking at its inputs and outputs? Yes, sometimes.

Will it be a full copy of the original algorithm - the same exact implementation? Often not.

Will it be close enough to be useful? Maybe.

LLMs use human language data as inputs and outputs, and they learn (mostly) from human language. But they have non-language internals. It's those internal algorithms, trained by relations seen in language data, that give LLMs their power.

I think not necessarily. It also means freedom and power.

The flip-side is: you need the money more than your employer needs you. Which puts you in a bad position to negotiate salary, makes it hard to stand-up against bad decisions, etc.

I think that it can (not sure if the author meant this) also mean that you have a buffer and are OK with switching jobs, but are also in a position where your employer wants you (because of something you can do). This puts you in a GREAT negotiation position.

And unfortunately it has become the norm in open-source to push out shiny-looking projects with pretty logos and UX but shoddy underlying technology and deceptive/overstated claims (looking at you Tauri).

Thing thing uses RDP for communication which was designed for remotely administering servers over low speed networks.

VirtualBox in contrast integrates at the driver level, and allows you to share the underlying GPU buffers, giving you a native experience that works for things like games or heavy apps. It integrates the Linux filesystem on a driver level as well.

Einstein's proof relies on the fact that the theorem works with any shape, not just squares, such as pentagons: https://commons.wikimedia.org/wiki/File:Pythagoras_by_pentag...

Or any arbitrary vector graphics, like Einstein's face. So in the proof, the shape on the hypotenuse is the same as the original triangle, and on the other two sides there are two smaller versions of it, which when joined have the same area (and shape) as the big one.

Fair enough. However, none of the hundreds or thousands of proofs explain it. They all prove it, like by saying "this goes here, that goes there, this is the same as that, therefore logically you're stupid," but it still seems like weird magic to me. Some explanation is missing.

- 4e12 transistors in 46,225 mm^2 (8.65e7 transistors/mm^2), basically an entire wafer squared off.

- 5 nm process in current third gen.

- RAM is spread out "IRAM"-style.

- Most of the server packaging space is taken up by DC power supplies.

- No decoupling capacitors.

- Executes dummy operations to prevent "inductive transient"-like backlash from changing current draw too quickly. [I cry in reversible computing.]

- Custom core, not ARM.

- "~20x faster" than NVIDIA GPUs.

- In customer production use now including US National Labs.

- 2 WSE-3 systems per rack, so that's 50 kW/rack and therefore needs watercooling or rack-dedicated airhandling.

Housing in higher-density areas currently has a higher cost per square foot than it does in the suburbs, implying that unmet demand for it is currently higher than demand for suburban real estate. You'd have to build enough to make that not the case before anyone who doesn't want to live in a condo would have any reason to choose it over a similarly-sized house. And if you actually managed that then it would be from building enough condos to make them more affordable, which would start attracting some people with only a weak preference for a house and still make them better off because they'd get lower housing costs. Meanwhile the people with a strong preference for a house would just pay the extra money for a house, which in the long term would still be less than they're paying now because there wouldn't be so much housing scarcity.
Ask HN: Practicality of harnessing geomagnetic fields for electrical generation?
by keepamovin | 2025-11-29 10:46:14+00:00
Years ago I would have asked this on the 'Overflows. Alas, those innocent days are long gone. I could always ask AI, but how can you know?

The Earth produces a moving magnetic field (small teslas, but large extent yes?). Moving magnetic fields produce electrical current, right? Could you add "geomagnetic power" to other clean/renewable sources with the right technical solution, or is it fundamentally impossible?

I haven't looked sufficiently into it - on a quick read it seemed like a positive public standing against censorship. I have noted a number of left-leaning figures in the list and even more centrist ones, not necessarily from the UK though.

Left-leaning: Žižek, Stone, Varoufakis, Hedges, Sachs, Liu;

Centrists: Assange, Snowden, Robbins, Fang, Maté.

The majority would likely be to the right of the centre, closer or further away.

I suppose that some degree of interpretation will come into it in absence of a clear definition and self-expression of political adherence. Some of those could be catalogued as nothing more than Hollywood progressive liberalist, some radical civil-libertarians etc.

Not the idea but in reality without government initiated land forced sale you need

1. Someone(s) to agree to sell some land

2. Usually several adjacent plots to have enough space to build - get them all to sell

3. Planning permission

4. Zoning (but we assume that is fixed here)

5. Profit in the proposed development

6. The buyer

So a lot is needed. Now game theoretically it may be better to be nimby.

Also some people wont sell they are sentiment motivated.

I noticed there is a split how this topic is discussed in (center-)left and (center-)right circles.

The right generally takes as a given that the cause of the problem (if there is a problem at all) is that there is not enough housing and we just have to build more.

The left argues that in we in fact do have enough units that could be used for housing (or at least the situation is not as clear-cut), but that other factors prevent them to be available at affordable prices, like the effects of extreme income and wealth inequality on the market.

Personally, I think the "left-wing" explanation makes more sense - at least I've never understood where that sudden shortage of physical housing is supposed to have come from. We neither had a population explosion, nor a war or catastrophe that would have destroyed a lot of houses. So then why would there have been "enough" housing in the past but not anymore today?

This had me scratching my head. Why would a base64 decoder need to skip spaces? But indeed, MDN documents this behavior:

Developers build what's profitable, i.e. what's in demand. And they don't have to build the thing you want to make more of it available to you. You want a big house, someone who currently has a big house just wants a place to live, so if someone builds them a 1-bedroom then they take your money, pay a fraction of that for the 1-bedroom and pocket the difference. They get the new unit and a pile of money and you get the existing bigger house.

That continues until demand for bigger units starts to outstrip demand for smaller units, at which point developers start building something else.
Show HN: FISE – A rule-based, keyless semantic envelope for web/API data
by anbkit | 2025-11-29 10:49:51+00:00
Hi HN,

I've been building a small open-source project called FISE, a rule-based "semantic envelope" for web/API data. It's not cryptography and it doesn't try to replace TLS/AES. The goal is to raise the cost of scraping and reverse-engineering client-visible data while keeping the hot path simple and fast (linear-time, parallelizable, works for JSON and media segments).

Key ideas:

- Keyless by design: no long-lived client-side decrypt keys. - Rules-as-code: offsets, length encoding, salt/meta layout, and optional transform are defined as per-app/per-session rules. - No protocol-level universal decoder: each deployment (and even each session/time bucket) can have its own rule family. - Temporal & distribution polymorphism: rotate rules per session/route/time so any decoded pipeline tends to be short-lived and non-reusable. - Simple local ops → emergent complexity: the core ops are just linear byte transforms, but the rule space and rotation make envelopes hard to generalize at scale. - Works for JSON and media (video segments) with framed/chunked mode, block-local decode, and parallel workers.

Threat model:

- In scope: automated scraping, bulk API harvesting, cheap cloning of curated datasets. - Out of scope: strong secrecy for secrets/PII (use TLS/AES/etc.), full client compromise, nation-state adversaries.

Engineering whitepaper (v1.0): - https://github.com/anbkit/fise/blob/main/docs/WHITEPAPER.md

Code: - https://github.com/anbkit/fise

Demo: - https://demo.fise.dev/demo

I'm a full-stack developer, not a cryptographer. FISE came out of working on real projects where API JSON data was exposed on the client side and could be easily scraped. I built it as a simple, rule-based layer to raise scraping cost, and I'm sharing it so others can review, critique, and improve it.

I'd love feedback on:

- The security model & threat boundaries (what did I miss?), - The "rules-as-code" design and the idea of temporal/distribution polymorphism, - Practical deployment concerns (CDN/normalization, mobile/TV/edge), - Any obvious pitfalls or prior art I should explicitly reference.

Thanks for taking a look.

Are multiple LLM queries faster than vector search? Even with the example "dog OR canine" that leads to two LLM inference calls vs one. LLM inference is also more expensive than vector search.

In general RAG != Vector Search though. If a SQL query, grep, full text search or other does the job then by all means. But for relevance-based search, vector search shines.
by phforms | 2025-11-29 10:51:16+00:00
Maybe the structure and operation in LLMs is a somewhat accurate model of the structure and operation of our brains and maybe the actual representation of “thought” is different between the human brain and LLMs. Then it might be the case that what makes the LLM “feel human” depends not so much on the actual thinking stuff but how that stuff is related and how this process of thought unfolds.

I personally believe that our thinking is fundamentally grounded/embodied in abstract/generalized representations of our actions and experiences. These representations are diagrammatic in nature, because only diagrams allow us to act on general objects in (almost) the same way to how we act on real-world objects. With “diagrams” I mean not necessarily visual or static artefacts, they can be much more elusive, kinaesthetic and dynamic. Sometimes I am conscious of them when I think, sometimes they are more “hidden” underneath a symbolic/language layer.

> Why wouldn't the people who prefer this just take the developer's money, buy another house somewhere that hasn't been rezoned and pocket thousands of dollars?

This one is obvious - they want to live close to where they've lived so far, and they want to stay in their house. Rezoning will inflate the house prices in the vicinity (because of the effect that you're describing of people moving close) so the residents won't feel confident that they can keep affording that area, and won't be pushed out into the countryside.

> Individual flats will be somewhat more affordable than they are now because supply will increase.

This works if the supply will overwhelmingly (in the scale of the entire metro), exceed demand. Here multiple things can happen. One is that demand increases with supply, prices of the apartments go up and match the prices of houses, and prices of houses will grow like you predict. The other one is that people don't want to live in a mixed zone neighborhood, the developer won't make money, so they'll build cheap slum housing instead of normal housing, and the value of the houses in the neighborhood decreases with the new construction. This really depends on the real world situation, and can't be accurately predicted with a supply and demand model.

> Higher density areas allow mass transit to become viable, which reduces car traffic.

People from the burbs don't want to take the bus, so they won't vote for that.

> To begin with, if you convince them then they vote for something else.

Good luck with that, but if you look back in 10 years, we'll be in the same spot.

> Moreover, the status quo is self-destructive. As prices go up, fewer people can afford a home, and then if it's homeowners voting for the status quo, they become a minority and get overruled by the growing number of people who can't afford housing.

This assumes the majority will vote according to their interests. They likely won't. The power to manufacture consent is still with the owning class.

It’s not exactly unknow. My nan lived in a big 3 bed semi in the midlands, but my grandad was bed bound and lived in the conservatory for 7 years. He had a portable commode but having a flushing toilet would have worked too.

Sometimes health means having a toilet in your bedroom is more important, and having a door is meaningless when you can’t even get into the toilet without two carers lifting you there.

Which perverts?

If you want to share a room get a bed in a hostel. Is sharing a room with strangers - or worse work colleagues - really that common in the US?

What do you do with the bed? Or are you happy lying asleep next to a stranger , but not having a shower in sight (even if the shower was really open to the room which I can’t think I’ve ever seen)

What do you do at the gym/spa?

First, many people are ... let's politely call it arithmetically challenged. They won't understand how to compute the amount and then obtain the correct dose. A chart or a table might have more success than a formula, no matter how simple the formula.

Then again, the dangers of paracetamol overdose aren't high (and I would think it's less for children than for adults). It's typically only needed for a few days. Perhaps that's where the stress should go: stop as soon as you can.

I don’t know what airbus uses I only looked into the schematics of commercial avionics like Garmin. I doubted though IMU drift and calibration introduce more error than they can provide in useful signal, old school pressure sensors + gps adjusted manually or automatically for regional pressure settings (pilots get these numbers through radio when they enter a new pressure area) is accurate enough (~1m). I’ll let a real avionics engineer correct me here, I’d be curious if that signal is worth the hassle + I can imagine such tiny SMD sensors ARE the biggest victims of radiation hallucination.

Problem is, eventually everything ends badly. You can make this argument about "average S&P500 company", and the time in which it ends badly has gone down over time. In the last 10 years the average S&P500 company ends badly after about 18 years.

If memory serves it was about 30 years in 2000, and much longer before that.

By contrast most of these mania lasted a lot longer.

Then you'd have to add a wrapper script to su and similar programs that unsets all relevant environment variables. That set is not necessarily fixed; a future version of glibc may well require clearing NSS_FILES_hosts as well.

(This is about UNSECURE_ENVVARS, if someone needs to find the source location.)

Making these things more transparent is a good idea, of course, but it is somewhat hard. Maybe we could add Systemtap probes when environment variables are removed or ignored.

A related issue is that people stick LD_LIBRARY_PATH and LD_PRELOAD settings into shell profiles/login scripts and forget about them, leading to hard-to-diagnose failures. More transparency there would help, but again it's hard to see how to accomplish that.

Yes, of course, when their teachers learn to use a FLOSS desktop for all tasks, starting with writing theses and papers in LaTeX... In other words, when they run courses for students to recover what they didn't learn in high schools.

Today, a desktop is the primary epistemological tool; only a FLOSS one is suitable for study, as it reveals what it does and is, or at least can be, shaped according to need. Most are simply IT illiterate, like professors from the 1950s unable to read and write fluently, except they still haven't realised it...

> less than they're paying now because there wouldn't be so much housing scarcity

And now we’ve circled back to where the owner of a big house looking to downside isn’t made better off.

Housing policy is complex and tied up in economics and emotions. Arguing (as you seem to be) that all users of housing are made better off by a policy change that’s so simple and obvious that no one has tried it is going to leave many people more skeptical of your idea, not less. Arguing “these users are made better off at the expense of these other users is probably more accurate and more persuasive”; if you can’t find anyone made worse off, it’s possible you’ve cracked a problem facing society for well over a century, but it’s more likely that you just have thought/looked hard enough.

But to what extent should we care for such a small website? The AI witch hunt won't get us too far, and this new way of producing is only getting started.

I agree and I do not agree. I still sometimes use a Thinkpad X230, and wait- a G4 PowerBook, and they are fine machines for many tasks. Yet even those have soldered CPUs, simply because of design constraints.

You don't need to have to train models. You want to play a game like Factorio, that, of all things, is bottlenecked on memory bandwidth - you must update each entity in a huge world on every tick, at 60 UPS, and yes, the game is insanely well optimized (check the dev blog). You don't have to play Factorio, but you also technically don't need DMA.
