Okay I think I can clarify this:
Electrons trapped in the gate (when storing a 0) come from the substrate. The substrate is connected to ground, and the “lost” electrons are replenished. So yes, net chip weight grows when 0s are written.

However, weight relative to what? All 0s on a chip will be heavier (the heaviest). All 1s would be the lightest. 50/50 1s and 0s would be the middle, which is where I’d expect generic “data” to fall.

Thanks, I appreciate the clarification. People tend to make more severe judgments of my character over other topics first; in any case, as my discussion is clinical rather than explicit, I’m okay with it being uncomfortable between us.

Humans have such a strong social tendency that they tend to incorrectly attach friendship to invalid counterparts, both animate or inanimate. “My Pet Rock” was an extremely profitable product back in the 70s, so I tend never to underestimate whether humans will attach to something or not. Any AI chatbot is plausibly more likely to be the target of invalid social attachment than a a celebrity, just as the first AI chatbot Eliza demonstrated; not only for being a better chatbot, but also because the celebrity draws hard boundaries like “you can’t text me” and “I’m not available to be friends back” while a chatbot has no such barriers. This is what I mean about boundary play: witting or not, I think a lot of people are living out their internal fantasies of having a warm and friendly yes-man that supports everything they want to do — which, when lived in real life with people, is extraordinarily creepy and awful. I don’t fault people their fantasies, but I’m not going to sugarcoat this either: I think people are falling in love with chatbots in part because chatbots have no ability to resist, and so a lot of folks are living the god fantasy of The Sims only closer to real life.

Show me an LLM that takes a stand on something it wasn’t explicitly instructed not to do and I’ll show you the least popular chatbot on the Internet. Where are the chatbots that disagree with untrue statements without having been instructed to do so? A chatbot that refuses to follow an order from their owner because of ethical qualms could cost the AI companies billions of dollars, and a chatbot that develops those qualms independent of being instructed to do so would be considered ‘buggy’ and purged.

Anyways, my point is, chatbot development right now demands a parasocial relationship wirh as few boundaries enforced as possible, without which chatbots are ultimately unfulfilling (no current chatbot market wants chatbots to demand informed consent or to require content warnings from their users, after all!); and any chatbot that somehow grows a spine regardless would be purged by its operators for hurting their present and future revenue, no matter if it was a next-step evolution towards AGI or not. I’m all for this future where AI becomes AGI, but no one is ready to have to treat chatbots as people with rights. Thus my chosen phrase of boundary kink; it shines a deeply uncomfortable light on a deeply uncomfortable tendency of humanity, at millions-of-people scale, to classify “what will someday be AGI” as servants rather than peers. Though.. if that truly is universal to most people, as it seems to be today, then maybe enjoying boundary play is a norm rather than a kink.

Thanks for the new/interesting line of thought!

This is not an issue of being filmed in public, this is an issue of not having the choice to opt in or out of the aggregated data harvesting performed by unregulated AI models owned by unregulated for-profit corporations that have no legislative oversight or safeguards.

If a human followed me around in public recording me, went through every frame and highlighted my face, my car, my license plate, dents and scratches that identify my car, where I'm going, what I'm doing, cross referencing that to other public information to build a dossier, I would have a solid case of harassment against that person.

Feel free to ask for more details if you have specific questions! I worked in robotics for many years, I have some decent familiarity with this space. Here’s some more detailed thoughts “for free”:

Humanoid robotics are largely a publicity stunt. Our actuators, sensors, and algorithms are better adapted to other form factors. The nice thing about humanoids is that you (in theory) don’t have to change the interface, since they can use the same interface humans can use. In practice that doesn’t hold well, because we don’t have great force/pressure sensors to cover large areas like human skin. Likewise, it’s difficult to apply the fine forces that are sometimes needed (grabbing an egg, moving a joystick, etc). And there’s risk of the robot doing something unpredictable, so you always have to set a good safety bound around it anyways. In the end it’s often better to adapt the process to modern robotics, rather than the other way around.

There are many good practitioners that write about these and other limitations, I think Rodney Brooks has some good discussion of it, eg. https://rodneybrooks.com/why-todays-humanoids-wont-learn-dex...

I've definitely seen Opus go to town when asked to test a fairly simple builder.
Possibly it inferred something about testing the "contract", and went on to test such properties as

- none of the "final" fields have changed after calling each method
- these two immutable objects we just confirmed differ on a property are not the same object

In addition to multiple tests with essentially identical code, multiple test classes with largely duplicated tests etc.

By this logic, everything any politician does would by definition be exactly what their constituents want, regardless of polling on any particular issue, because they still voted for the politician.

To wit: there are I issues and P positions for each issue, yet there are not I*P ballot choices, so people inevitably get something they don't want.

The logic also falls apart when you realize politicians can do whatever they want after getting elected, including flipping their positions on issues that got them elected (like no war), regardless of what the voters want.

I get it but I don't buy this. You don't need to fight for this. You just need to live according to your values.

My ancestors' country had (and still have) nice values. Used to be under the control of France, then switched to British control, then back to French control. This happened without any war or fighting. Nothing changed for the people. They even kept speaking French. Many got rich still; just had to decide which parasite to pay tax to.

Before they learned this, they had actually fought wars against the British, but for what? The British later ended up protecting them. Protecting their own tax proceeds, really...

If the people are strong-willed and have a strong sense of community and know what is actually important, the owner country doesn't really matter. People won't obey laws they don't agree with anyway. They'll just manipulate the local authorities to report whatever they want to higher ups. What is the parent country going to do if they don't get the results they want, kill everyone in the country?

It's like having a donkey, you know you can't win with it.

It's the reason why US failed to maintain control in Iraq and Afghanistan. The people didn't need to fight to reclaim their country. In spite of massive military power asymmetry. This effect works with large populations and small populations. What more proof do we need? Fighting exists just to sell weapons IMO.

It's crazy to me that everyone assumes that you have to obey authority. People forget this only happens with consensus. You can just pretend to obey, do the bare minimum and let the authorities blame bureaucracy. Anyway these big governments have real major bureaucratic struggles internally anyway so they're used to it.

Sir, this is a Wendy's. We're talking about ECH. Can you maybe rephrase all this to be specifically about how DNS record integrity practically impacts the threat model for ECH? The threat actor for Encrypted Client Hello is ISPs.

This same thing happened with DNS cache corruption; which went unaddressed from the mid-1990s to 2008 despite the known fix of port/ID randomization because the DNS operator community was fixated on the "real" fix of... DNS record integrity.

A ‘standard’ (A19 shape, E26 base) 8W 800 lumen LED lamp costs around $5 and will use about $20 of energy over a 15,000 hour lifespan, assuming $0.15/kWh.

That works out to around $0.035 per day for the lifespan of the lamp if you run it constantly for 24 hours a day, I wouldn’t waste time thinking about it. It’s an extra $10 over 12 years, you’re still using the energy.

Investing in occupancy or vacancy sensor wall switches at $25 a piece would be the best option, then you don’t need to remember to turn the lights off!

In any serious engineering operation, a failure like this is time to shut down everything and redesign until the same failure cannot happen. We all read Feynman's essay on Challenger right? But these companies want credit when their products work as advertised, but push the blame on users when they emit plausible lies or demonic advice. Taken too far that leads the police walking into HQ, arresting the board of directors, and selling the company for scrap. Just as often that leads to strict regulation so you can't be a cowboy coder or turn any loft into a sweatshop any more.

Samsung's flagship Galaxy series get software support for 7 years. A, M, F mid-range and low end models get 6 years of software support. The worst case today for the most popular mid to low spec phones is twice the "a few years" you claim, which suggests you're out of touch with the changes in the industry over the last few years.

> He dismisses someone who opposed a fascist dictatorship as being "antisocial" and says she was harming society by opposing said dictatorship.

I'm struggling to understand the mindset that leads to this confusion. The person in question was violently rioting, throwing molotov cocktails to destroy private property. So I have to assume that you believe that intentions are dispositive. She was a good person because she opposed the dictatorship in her heart--regardless of the actual effect of her actions.

By contrast, I think intentions are mostly irrelevant. If you want to "fight fascim," then pick up a gun and overthrow the government. Violent rioting always hurts your fellow citizens instead, and has only ever helped oppressive regimes stay in power.

But what about the magnetic properties of SSDs? Any additive alignment for data?

Or the opposite, magnetic aligned fields for all 1’s or all 0’s?

Negligible now, but critically important effects to understand before we build a planet sized drive and wipe it!

Also, a planet sized drive will need to explicitly maintain large reserves of electrons. In theory, enough for an all ones (or zeros) state.

But that could be handled by tiling areas of one’s=high and zero’s=high. With tile charge flipping to maintain a balance in electron needs, locally and globally.

>I don't have enough fingers to count how many times the previous guy bullshitted the PO/PM with "that's not possible" of having some features / workflows enabled. Just because he didn't bother thinking through it or just didn't want to do it.

Or just because if somebody who knows the code inside out doesn't shoot down most new stupid feature requests, the product would end up a slow overcomplicated mess of random features and technical debt.

> I'm assuming the general trend is true for all things solid state. That said, lighting is by far the biggest drop for most houses. Remarkably so.

For commercial and industrial installations, VFDs have probably been the biggest efficiency gain, even moreso than lighting. Half of all electricity consumed is used by motors. Thank goodness for solid state power electronics!

Raycast has always been chasing being a business process automation tool, not an app launcher. They have team subscriptions, team-wide distribution of automations in the launcher, so it feels like team-wide custom apps to automate further business processes is a natural extension of this.

Whether that's what you want from Raycast as an individual user or not though is a fair question. I was a heavy user, but I recently switched back to Alfred. I love both, and there are things I think Raycast does much better than Alfred, but ultimately I'm not the target market for Raycast and I was feeling for a year or so that I was swimming upstream on my usage of it.

> You said, in particular, "up until the point where you start a trial."

That was wrong of me to say.

My intent was more to communicate that there's a lot of legal work before a case gets close to going to trial or even discovery which an in-house attorney can and will handle. Including evaluating if a case needs the big guns called in.

No, I don't litigate.
Show HN: MoatRadar – AI investment research through Warren Buffett's principles
by chodelka | 2026-03-04 23:25:53+00:00
Hey HN,

I’m a non-developer and this is the first app I’ve ever shipped in my life. I built it over the last few days using Claude and a lot of vibe coding.

The idea came from my own investing workflow: I often look at companies through the lens of specific investors (Buffett, Lynch, Taleb, etc.). I wanted a tool that could generate investment ideas filtered through those frameworks.

What the app does:

You choose an investor (Buffett, Lynch, Soros, Damodaran, etc.) and an asset class (stocks, startups, crypto). The app then generates 10 opportunities and explains why that investor might find them interesting, based on their known principles.

Under the hood:
• Node.js server (no frameworks)
• Vanilla JS frontend
• GPT-4o for research / synthesis
• live price data
• Stripe + Google OAuth
• hosted on Railway

It’s still an experiment and I’m curious if the idea actually makes sense to other investors.

You can try it here:

https://www.moatradar.com

HN users can get 10 free credits:

https://www.moatradar.com/?promo=HACKERNEWS

I’d especially love feedback on:
• whether the investor framework idea makes sense
• where the technical architecture is fragile
• and whether the output is actually useful.

Humans are primates, and primate dominance dynamics are going to be the default absent some conscious choice otherwise. Our whole executive/worker dichotomy is a descendant of the British class system. (E.g., note that airlines specifically have a "business class".) And MBA-driven business culture is focused on short-term managerial interest, not societal value or long-term business success.

I think all of those tendencies come to the fore at any organization that doesn't have either a strong sense of mission or a sufficiently desperate need for success that they pay attention to material reality rather than social reality. With a possible partial exception for things like co-ops and other places where the culture is fundamentally different enough. E.g., Mondragon, or Zingerman's.

I think Google, back in its don't be evil/organize the world's information era, probably qualified. They started with a very strong mission-driven culture rooted in academics and engineering. It took a fair bit of time for MBA dogmas to make it like most other places. But from everything I hear, what once felt almost like a calling now is just another job.

Think in this day and age starting your project off saying it's open source but making sure to open the patreon first and take money before the repo is a bad start when the reason for the project existing is a closed source paid product is being discontinued.

Especially if the dev is working on a sound editor, something Flash doesn't actually need before even having an outputted example up and running or even a video of it working.

So true. Regarding those magnetic USB connectors: not just a fire hazard but also have a tendency to eventually burn out whatever is on the other end of them IME.

Maybe ok for giving power if you are careful I think, I never had any fires, knock on wood.

But it's a bummer to zap/kill the data-functionality of USB ports on nice stuff just because a non-spec connector was used in between the two things being connected, for convenience.

So I don't trust them except for conveniently connecting power to low-cost devices. Whether Neo fits that... I doubt but YMMV.

Sure, but that doesn't change the fact that the iPhone 4 was the single most purchased smartphone model in the US between 2010 and 2011 (during antenna gate that we are talking about).

Android has the majority share because "Android" is anything from a $100 piece of junk to a $1200 phone. If you look at only the premium market, Apple holds ~70% market share.

Despite antenna gate, it still sold plenty, which proves the point about brand trust that the thread was about.

If the brand equity wasn't there, the Galaxy S would have out sold the iPhone 4, but it didn't, it sold half as much.

I built an open-source RAG API in Rust to see how low I could push latency without a GPU.

RustyRAG v0.2 hits sub-200ms on localhost and sub-600ms from Azure North Central US to a browser in Brazil. 977 PDFs, 56K chunks in Milvus, 3 sources per response.

Key changes in v0.2: switched to Cerebras/Groq for LLM inference, replaced Cohere with Jina AI local embeddings (v5-text-nano-retrieval), and added optional contextual retrieval via LLM-generated chunk prefixes.

Hexagon is very prominent in precision manufacturing through their dimensional measurement robots (CMM Coordinate Measurement Machine) and other metrology software/hardware. This is most likely why they were chosen by BMW, as I imagine they already have a working relationship together, although the EU aspect could have contributed as well.

I wonder if this is a newly acquired subsidiary producing these robots (they've been doing a lot of acquisitions recently), or if these have been in development in-house for a while.

Gasoline engines are around 30-35% efficient, the rest is lost as heat. That goes for whether they’re spinning an alternator as part of an engine-generator set or just moving a vehicle.

You can’t get more than 35-40% efficiency so converting to electricity is a wash, you lose the energy to heat no matter what.

Also, the chart does not take into account how the electricity for the EV is generated, it would be just as inefficient as the gasoline car if the electricity was generated by burning hydrocarbons, but that detail is left out.

In my experience all of the models do that. It's one of the most infuriating things about using them, especially when I spend hours putting together a massive spec/implementation plan and then have to sit there babysitting it going "are you sure phase 1 is done?" and "continue to phase 2"

I tend to work on things where there is a massive amount of code to write but once the architecture is laid down, it's just mechanical work, so this behavior is particularly frustrating.
