Trying to put your bizarre ethnonationalism aside, as HN is not the place for that:

Firstly, you're conflating German and Germanic, while ignoring that the common ancestor here dates to before the High German consonant shift between the 3rd and 5th centuries, that further split the German* languages, that had already long since split from the other Germanic languages.

Secondly, my point was merely that there is a closer relationship between the Germanic languages historically spoken around the North Sea, than with modern standard German that has carried with it the consonant shift, and so if you take into account Low German/Plattdeutsch, the similarities are more visible and obvious.

I see no reason to try to mush them together, but it would be interesting to see German take the approach of Norway: Norwegian have had a few fairly successful reforms actually moving it further away from Danish in some respect, but which also in some respects have mean allowing older forms closer to Norse in the majority form of Bokmål, that were retained/included in Nynorsk.

If German did the same thing and started encouraging and allowing those of the forms of minority Low German dialects that are closer to the older Germanic forms (e.g. Dag instead of Tag, for dag/day), it might over time restore some of the continuum.

The sun is greeting you! I drew these freehand, kind of quickly. And while I personally like the style and think it's a good fit for us, I did intend to make several sets of weather icons. At the very least I need to make the sun symbols adapt to the seasons - we don't really have a full sun during the darkest months of the year where I live.

I know a number of Jehovah's Witnesses children - I don't want to call their children 'Jehovah' since they have not made the choice to be born in those circumstances - who also don't celebrate birthdays but notices they have other 'gift-giving' days which seem to fill the hole left by the missing birthdays. Just like Jews manage to get around the rules for Sabbath by installing special light switches [1] which use random events to accidentally switch on and off the lights so the one who actuated the mechanism did not have someone or something do work for them also Jehovah's Witnesses seem to find ways to get around the restrictions their traditions put on them.

Some have inverters for continuous power adjusting, others turn on and off the magnetron.

In any case, all that I have ever used have 2 dials, one for power and one for time (and a button to allow to chain multiple time intervals, each with a different power level). I have always used only these 2 dials and I have never used any other buttons that may exist for preset programs.

For many years I have used microwave ovens only for reheating food. Now I consider that I was stupid and I cook all the food that I eat in a microwave oven, from raw ingredients.

This is much better than by traditional means, because it is much faster and perfectly reproducible. Moreover, cooking in a microwave oven removes the need for continuous or periodic stirring that is required in many traditional cooking methods, because the microwave-cooked food is homogeneous (without lumps etc.) even with no stirring, if the time and power level are chosen correctly.

There is a new way to train diffusion models to insert tokens between existing tokens rather than unmasking <mask> tokens: https://openreview.net/forum?id=VbvXjs5f72

However, I believe this would "only" be able to insert tokens, not to delete tokens again it mistakenly produced before. (The deletion in the title refers to the reverse process during training, where tokens are progressively deleted rather than masked.)

This is a valid observation. Capital breeds more capital and just like water seeks the lowest point capital will seek to enable those who are willing to bend or even break the rules. This is embodied in YC's application questionnaire in interesting ways, it is effectively capital testing for exactly those properties. I think 'ethical' should be made explicit in your list, and not lumped in with 'other'. Because that is one of the more important ones and it usually is also the first to be thrown out.

Amazon doesn’t for the most part deliver shopping on top of AWS.

Amazon runs two sets of infrastructure “CDO” and “AWS”. It’s a myth that Amazon used excess capacity to start AWS. AWS was always built out as separate infrastructure outside of AWS.

Some Amazon services do run on AWS. But when Amazon runs workloads on AWS, for internal accounting, they are considered a customer.

I've heard of Chris but not too well. This guy does not f*c$ around, don't get on his bad side.

The state of research is dire at the moment. The whole ecosystem is cooked. Reproducibility is non-existent. This obvious cartel is a symptom and there should be exemplary punishment.

Publishers are commercially incentivized to simply maximize profit and engagement. The main actors are academics and most of them try to uphold the high standards and ethics. Yes there is free-riding, backstabbing and a lot of politics but there is also reputation and honesty.

A few academics give academia a bad name, at the worst possible time and when society needs honest, reliable, reproducible and targetted research the most.

i could have been clearer about that. but yeah, even for what i paid, i was happy to immediately be off to the races designing the couple panels within their web portal and having something functional and useful to me without any real friction from having to figure things out.

moving on to the self-hosting side is probably now backburnered indefinitely, even if i do have some grander ideas in the longer term. unfortunately, i'd need more than a weekend project's timeframe to bring them to fruition.

Paying almost a thousand - or more! - to have an overcomplicated device filled with sensors put into your most private sphere voulnerable to adverse elements unnecessarily (had a perfect dumb robot vacuum doing its job loaned to us once, but no-one sells such when they can sell bullshit for 4 times more, idiots buy it regardless), that is not smart....

Consumidiotsm, is the term comes to mind. Eating up crap, is the analogy from non-technical contexts. The side effect is, that buying properly made not overcomplicated and tedious to maintain (update, refresh, pair, disgnose, update and configure connected harware, click away pushy self-promotions, the way it is not exposing you to the manufacturer or everyone) products is tedious (loosing saved efforts). Poor others just want simple and robust, not fragile and risky tech-crap doing the core thing are left out.

(Robotic vacuum is a great concept! The available implementations in the other hand are rubish!)

Rural surveillance was far more suffocating because every single action was subject to the community gaze. This is exactly why classic literature frames the journey to the city as a liberation from the crushing weight of the village eye. The idea of the peaceful countryside is a modern utopian fantasy that ignores how ancient clans dictated every aspect of life including marriage and death. Modern Homeowners Associations prove that localized oversight is often the most intrusive form of management. Ancient society did not just monitor people; it owned their entire existence through inescapable social visibility.

It's a viewpoint issue: how you define success is what makes the difference here.

To someone that just made a few billion and who externalized the cost of that billion, say 100 billion onto society they are successful. From the point of view of society they just cost us all a fortune. But we don't judge the winners by social impact but by the size of their bankroll.

I assume that -p is the same that "codex exec".

The difference is that in this case the agent loop is executed, which has all the caching and behaviour guarantees. What I assume OpenClaw is doing is calling the endpoint directly while retaining its own "agent logic" so it doesn't follow whatever conventions is the backend expecting.

How important is that difference, I can't say, but aside the cost factor I assume Google doesn't want to subsidize agents that aren't theirs and in some way "the competition".

Yes, but if you were that unit, would you get stuck in a corner, or would you persist in trying to find your destination? I suppose if you make it all the way to the target, you've accomplished pathfinding of some kind, by definition, sure. But an algorithm to avoid getting stuck doesn't have to be "pathfinding" as in an expensive algorithm to find a complete path right away.

"After spending time on Apple’s M1/M2 Macs (coming from a large x86_64 desktop), going back to x86_64 feels like a regression, both in performance and battery life. Unfortunately, there’s currently no FreeBSD-supported (or even Linux, as far as I can tell) ARM64 laptop that truly rivals Apple Silicon. I really hope Framework or someone else changes that in the coming years."

I thought it was now well established that it's not neccessarily ARM vs x86, but more "All the optimization of MacOS" vs "Bloated Windows" and "Sub-optimal (hardware control wise) Linux"

Am I wrong?

I have a PhD in physics and I read Hawking's book as a child.

You just got me to realize that while I've read many physics popular books that have been "simplified enough that the common person can get something out of them, but not so much that they become meaningless", maths books that achieve the same are much rarer, I think.

Immediate mode GUI is the way to go.

Retaining state is a pain and causes bugs. Trying to get fancy a la react and diffing the tree for changes makes not sense. That was a performance hack because changing the DOM in JS used to be slow as hell. You don't need that.

Just redraw the whole thing every frame. Great performance, simple, less bugs.
Show HN: Air Blackbox – Open-source audit trail and kill switch for AI agents
by shotwellj | 2026-02-23 11:38:14+00:00
AIR Blackbox is a flight recorder for AI agents. It sits between your agent and the LLM provider as an OpenAI-compatible proxy. Every request produces a structured OTel trace, gets evaluated against real-time policies, and is grouped into replayable episodes.

Four things it does: (1) records every LLM call as a tamper-evident audit trail, (2) enforces policies in real time — rate limits, budget caps, tool restrictions, kill switches, (3) redacts PII from traces before they hit your observability backend, (4) groups traces into task-level episodes you can replay.

The demo lets you run four scenarios — normal request, runaway loop (watch the kill switch save ~$47), PII in prompt (SSN/CC redacted), and a dangerous tool call (blocked before it reaches the LLM).

Setup is git clone + docker compose up + pip install air-blackbox-sdk. One wrapper function, no changes to your agent code. Integrations for LangChain, CrewAI, OpenAI Agents SDK, and AutoGen.

22 repos, 700+ tests, Apache-2.0: https://github.com/airblackbox/gateway

Most spinning robovac LIDARs are 2D. Most solid state robovac LIDARs are like 8x8 array of laser pointers.

Automotive LIDARs are like, 128x64[px] for production models or 1920x1080[px] for experimental models with GbE and/or HDMI-equivalents-of-industry outputs. Totally different technologies.

> There are always exceptions like Galileo

Well, considering that Galileo basically called Pope a fool, and the punishment he received was home arrest, this affair is not really the best evidence of Church prejudice, backwardness and cruelty.

And if we agree with Feyerabend, Galileo of today would probably has as much difficulty as the original one, for the initial evidence he provided wasn't strong enough to discard knowledge of that time.

> doing so would be a violation of their vows of silence

I don’t know what this means. There is no formal “vow of silence”. The closest things I can think of are the discipline of avoiding unnecessary speech in some monastic communities, or perhaps the seal of confession, but this doesn’t apply as priests can speak in generalities or anonymously about the kinds of moral issues people struggle with.

> Good homilies are written with the particular community in mind.

That’s a bit of a generalization. Many, if not most, readings simply benefit from clear explanation. Tying in local or cultural context can be helpful, but they can also be a distraction, and mostly, homilies should be about the essential meaning of the readings. By having to write the homily, the celebrant benefits from writing the homily as well, a benefit he would lose if he simply drew from a corpus of prewritten homilies.

I don't see the idea is visual tools, I never even heard somebody to talk about it like that. The plan is to target enterprise customers with advanced features. I feel like you should just go and watch some interviews or something where talk about their plan, Evan You was recently on a few podcasts mentioning their plans.

Also, the paradox is not really even there. JS ecosystem largely gave up on JS tools long time ago already. Pretty much all major build tools are migrating to native or already migrated, at least partially. This has been going on for last 4 years or something.

But the key to all of this is that most of these tools are still supporting JS plugins. Rolldown/Vite is compatible with Rollup JS plugins and OXLint has ESLint compatible API (it's in preview atm). So it's not really even a bet at all.

That’s an impressive and thoughtfully structured system, especially at that scale. The use of symlinks and a separate version-controlled notes repository makes a lot of sense for long-term archival.

I’m curious — when working with such a large collection, how do you typically rediscover material or connect related ideas across different parts of the hierarchy? Do you rely primarily on directory structure, full-text search, or your notes as the main index?

And as you move toward merging the PDFs and notes into a unified system, do you see the notes becoming the central navigation layer, or will the directory structure remain primary?

I had until now (in Europe, for somewhat more than the last 2 decades) a couple of Panasonic microwave ovens.

Both of them match your description. They had some other buttons, which I have never used. Besides the 2 rotary knobs, I use 3 buttons: start, stop and a button for chaining multiple time intervals, each with a different power level.

I cook all the food that I eat in the microwave oven, from raw ingredients.

There is the simpler version that is approximately "you can only get in if someone vouches for you. If a person you vouch for misbehaves you get punished as well". That's effectively a "tree of trust" with skin in the game. And it's incredibly successful, used in lots of communities, crime rings, job recommendations, etc.

Any attempt to generalize this by allowing multiple weak vouches instead of a single strong one, or allowing people to join before getting vouched for, or removing the stakes in vouching for someone, etc. always end up failing for fairly predictable reasons. No matter how much cool cryptography you add

One piece that I find interesting is how hopeful people sounded about tech that had access to your data. Folks higher up in the tech world often complain about how the media complains about them too much. And while the media definitely has issues in how they report, it's easier to see how we got to this point where tech is vilified. You compare the hope of the past and match it to the exploitation of the present, and you can't help but feel sometimes that in a game of picking straws, the current timeline picked dystopian over utopian.
by int_19h | 2026-02-23 11:43:09+00:00
One thing to remember is that not all users are going to max out their plan.

This is more likely to occur on $20 plans though, especially since those are often necessary to unlock the more useful features (e.g. deep research) so people might be paying for that even if they don't actually use the tokens.

OTOH someone who's paying $200 will likely want to squeeze the most out of their subscription for that amount of money. So I wouldn't be surprised if it turns out that $20 users are subsidizing the $200 ones.

The pathfinding algorithm has been decently optimized. The reality is that 600 units finding paths and keeping them up to date is a lot of work.

Some of the pathfinding is precomputed, some cannot be as it involves other units and formations.

Most other RTS games work around this by either relaxing the constraints or implement some amount of parallelism.
by embedding-shape | 2026-02-23 11:43:52+00:00
Well, depending on how you implement it, there might not be any way of getting unstuck, imagine a wall that is 3/4 circle for example, with a small opening, could it escape with that sort of naive algorithm? Players tend to be kind of sensitive to "stupid unit movements", and not having pathfinding is a great way of triggering that feeling in every play session.

Based on data and evidence that we now have? Yes.

Back then Galileo’s theory wasn’t exactly provable and while he did get the core idea right he was still wrong on quite a few important things.

e.g. Tycho‘s model solved quite a few questions that Galileo couldn’t at the time.

e.g. Stellar parallax was a big issue that was conclusively solved until the 1800s

Bit of googling suggests this is a whole, fascinating world of little improvements. However it's also both constrained and pushed forward by what's road legal.

https://www.volvotrucks.co.uk/en-gb/news/insights/articles/2... : removing mirrors allows for much smoother cab airflow

https://go2stream.com/blog/aerodynamic-truck-legislation-rea... : UK legalization of fishtail-like devices

https://www.kudauk.ltd.uk/aerodynamics-explained : Kuda on the UK allowing higher loads, and therefore benefiting from extra wedge devices on the top of the cab.

I'm sure there's a lot more out there. The eventual switch to electric will probably come with another round of aerodynamic improvements to maximise range, as with cars.

>it ignores the historical reality that human desires are infinite

This is factually false. Human desires are only infinite for things that have positive utility and cost nothing and by nothing I mean nothing. The moment you have to spend even a single second thinking whether you want to buy or not, demand collapses from infinite to finite by definition.

This means people will accumulate infinite quantities of money, stocks, etc, but never infinite quantities of anything concrete that exists in the real world.

That really depends on the kind of user interface no?

If you just have a lot of text and a few rectangles and no animation, immediate mode would work well...

But if you have a lot of images, animation etc ... You'd anyway have to track all the textures uploaded to the GPU to not reupload them. Might as well retain as much of the state as possible? (Eg. QtQuick)

> What's the issue? I've microwaved that long before.

Really? What for? Anyway the vast majority of microwaving is going to be in the 1-5 minute range. By making the dial linear and giving it a huge range up to 30 minutes, you end up making e.g. 30 seconds and 1 minute impossibly close.

The commercial microwave oven someone else linked had a solution - make it logarithmic.

> Seven presses?

Eight actually, but it really is quicker and easier than doing the same with a dial though. I agree it could be optimised though. It shouldn't be necessary to select the power and a 30s button would be good (down to 5 presses).

Some people legitimately think we can just suck hydrogen out of the air or ground and store it in tanks. (We can, to a limited degree, there's a fancy color attached to that kind of hydrogen).

Then when you attempt to explain that no, that's not how it works, we need to always separate the hydrogen molecules from another substance, which takes energy. A significant amount of energy. So much energy that it's better to shove the same amount of kWh to a battery instead.

The only vaguely useful thing for Green Hydrogen would be renewable overflow storage. When your solar/wind farm is producing too much energy for the grid, you shove it to an electrolysis station that converts water to hydrogen and pressurises it.

Then you pump that into a gigantic fuel cell when the sun is down or it's not windy anymore.

I don't know elisp, emacs keybindings, org-mode details, etc.
But I have vibe-coded a note/task management system using it that's by far the best one I've ever used. It's very similar to Dynalist (but much more flexible). It has changed my life, honestly.

Even though I use emacs/org pretty much adversarily, it works almost flawlessly.
Also looks pretty good imo [0].

I can capture notes/tasks to my inbox: by selecting text anywhere on my computer and pressing a keybind, by using a dialog provided by another keybind, from Quicknotes on iPhone, and from a webpage I have set up in case I'm using a computer/phone that's not mine.

I rsync my org files to a Dropbox, which allows me to access them on iPhone using beorg app.

Thanks emacs/org community! S2

Because transistors for generating even very low microwaves like 2.4GHz are extremely expensive comparatively speaking, and don't produce much power. They're good, though, because you can produce very precisely tuned and modulated signals and very precisely controlled output powers - as long as they're less than a couple of watts.

A cavity magnetron is a block of metal with some holes drilled in, two bits of glass glued on, and all the air sucked out. They're hard to tune to exact frequencies and hard to regulate to exact powers, and modulation is as you've already discovered kind of limited to just turning them on and off - but they're extremely cheap to make, last a very long time, and require minimal support circuitry to generate double-digit kilowatts of RF.

You don't need to be cock on frequency to heat up a pie.

Judging by the images only, those are all the ones I called "European" trucks though, the American ones are much longer. Is that also regulated so European trucks aren't allowed in the US and American ones aren't allowed in Europe? Because here in Europe it's really uncommon to see the US ones, and I'm guessing it's the opposite in the US?

One of them must be better aerodynamically though, must'n it?
