Because you can? It looks like a great project for getting started with nontrivial FPGA design.

Programming-wise I'd say full FPGA is less useful than QMK. Doing a direct 1:1 mapping from key inputs to USB HID report isn't too bad to do in an FPGA, but dynamic behavior like macros, layers, leader keys, mod tap, auto shift, and so on are significantly easier to implement in a regular programming language. If you want flexibility you're basically forced to have your FPGA run a soft core, so at that point why not go for a regular MCU?

In theory you could make an argument for lower latency, but that doesn't really apply when you're limited by USB 2's 1000Hz polling rate while some off-the-shelf MCU-based keyboards use USB 3 for 8000Hz polling.

Also not a lawyer, but here's what I recall: If you are a shop, and you produce copies of something with the intent to sell it, that's commercial use. If you offer some kind of production service, and someone hires you to make produce something, you are acting as their agent. If they have the right to make copies themselves, you can make copies on their behalf.

> 1.2 kW of solar power is a fraction of typical household usage.

Yes and no; it really depends on what kind of house you have, how many people live there, and (culturally?) where you live.

I have an 1800 sqft condo in San Francisco, and a 3.6-4.0kW solar system would be what I'd end up installing if I were to do it the "normal" route with an installer and all the "red tape". Yes, that's obviously 3+ times the 1.2kW demonstrated here, but even a system like that would be useful for me to reduce my electricity costs (especially given where I live).

I know people with more modest electricity needs than I have. I also know people who have 16kW of solar on their roof and that still isn't enough to avoid pulling power from the grid sometimes. So: yes and no; it depends.

I never planned & priced out battery storage, but, sure, 2.4kWh would be pretty low for my needs, but it would still be useful.

It's just weird that the article title includes the phrase "energy independence", when the author admits that they still pull more than half their usage from the grid.

Prototypes are routinely pushed into limited production for testing purposes. Someone has to sign-off on doing so but it has never been difficult to get that sign-off in my experience.

The operations chosen for that purpose are selected for their limited risk if something goes wrong. DoD wants capability evaluations to be as realistic as possible even if that means taking some risks. They understand the risk/reward tradeoff.
Show HN: Serve LLM – Spin up a hallucinated web app from a single prompt
by unbehagen | 2025-10-05 01:28:10+00:00
Why vibe code a POC to test your idea when you can have an LLM-based web server pretend to be that web app - and just output the HTML your visionary backend would produce?

Each request to the web server only retains the last generated HTML, the path, and any URL parameters passed to it. It is forgetful by design.

On page access, it instructs the LLM to generate the next page based on this information and a description of your desired app. The latency is much higher, but you can quickly iterate on ideas.

Obviously, this is more of a thought experiment, but I find it pretty interesting to play around with. Vibe-coded in a couple of hours. Any feedback welcome!

>* USAID shutdowns

The rest of the world is not entitled to unlimited American funds for all time.

>* DOE downsizing (ie. killing education)

Canada doesn't even have a federal-level education department. Is Canada filled with uneducated morons?

>As for the spacex contracts: a cheaper price only helps if it actually leads to less spending. Since the US cannot risk spacex being the only access to space, it cannot cut funding to ULA contracts. Therefore spacex is more expensive, despite the cheaper sticker price.

The mind boggles at this "logic".

The desire for having multiple launchers is not because "the US cannot risk spacex being the only access to space", but because the US got badly burned by putting all its rocket eggs into one space shuttle basket.

If SpaceX didn't exist, and the US government used ULA and Blue Origin for all its launches, the US would be paying far more than it is now. Don't believe me? Biden's NASA administrator Bill Nelson quoted a member of the Joint Chiefs as telling him that SpaceX had saved the US government $40 billion for just launching military payloads <https://www.fool.com/investing/2022/06/05/did-spacex-really-...>.

On the civilian side, SpaceX saved NASA $2 billion for just one payload, Europa Clipper <https://arstechnica.com/space/2023/10/a-year-from-launch-the...>, so who knows how many billions more from other launches.

The above is purely a cost analysis, and doesn't even cover SpaceX allowing the US to no longer being dependent on Russia for sending people into space, as was the case from 2011 to 2020.

So let's see for how long we can keep the ~3rd attempt to reflect this news item on this site viable... There was one person who said that none of this is true, the convoy was organized by Hamas, people in Gaza have done bad things like chasing nude persons through the streets, and the convoy didn't have any support goods on board; sources given were two articles from the Jerusalem Post. Anyone to weigh in on any of that?

I am basically all in on Stalwart right now, but do not have the time to deal with email deliverability issues or asking my VPS to open a port, so I have been using AWS SES as the SMTP relay for awhile. No problems so far, hosting about a dozen mailboxes for friend's and family's personal use. The whole stack is so lightweight, I have it on the cheapest Arm-based VPS at Hetzner.

My hope is that Stalwart will get to their webmail project over the next couple of years. I am on SnappyMail, but basically need to use desktop and mobile clients to get the full mail/CardDAV/CalDAV experience, which admittedly is already pretty awesome.

Currently, I have Stalwart, PostgreSQL, SnappyMail, and Caddy, all inside a docker-compose file, and I have migrated, moved servers, and all that no problem.

Taxpayers subsidize data centers in many other ways. These are prestige projects for politicians, so they often get long-term tax breaks and other preferential treatment.

I think it's part vanity, part a misunderstanding about the economic benefits of a datacenter (which are nearly nil, as they employ very few people and produce nothing for the local market), and part just a desire to score brownie points with wealthy corporations, which might mean donations, campaign support, or other perks for the politician who makes it happen.

This site is a front for Miome.

The home page cites IBSprobiotics, which cites Bailey Hanna MS, who is employed by Miome according to LinkedIn. Thus, it is no coincidence that if you follow the link to the top probiotic and then look at which products contain it, all the ones available in the US are distributed by Miome.

This is wildly deceptive marketing.

> It’s obviously a matter of precedent. If hoa allows that and then someone else decides to do something crazier, then association is liable for selective enforcement.

The obvious solution is to make it illegal for HOAs to have any say whatsoever in individual private property.

Shared spaces, shared amenities, common areas, sure. That's what it's for.

On private property, no absolutely not, that needs to be illegal.

The article author claimed they got their landlord's permission first, so I doubt they'll be taking it down when the landlord comes over. They'll just take it down when they move out.

Also... I lived in rented apartments for more than 15 years, and the only time a landlord entered my unit was one time when I explicitly asked her to (there was a water leak, and I was about to leave town and wouldn't be around to let the workers in to fix it). Is this a normal thing? Are landlords constantly visiting their tenants?

> HOAs can be a PITA and petty and I err on the side of less governance but some people are recalcitrant, stubborn and just set in their ways.

Recalcitrant about what? About using their own private property in a way they want (that doesn't violate city/state law)? Well yes, they sure should be. It needs to be illegal for any HOA to have any say about that.

If Tesla has a “no charge” list, they should at a minimum notify Carfax. However, everybody buying a used Tesla needs to be knowledgeable about this caveat. Tesla has a duty to inform the public. How they do this I have no idea. Perhaps the vehicle should never have been released back to the owner if it’s so unsafe. I don’t how that would work legally and financially.

https://en.wikipedia.org/wiki/1988_Hamas_charter

>The charter defines the struggle to be against the Jews and calls for the eventual creation of an Islamic Palestinian state in all of former Mandatory Palestine, and the obliteration or dissolution of Israel.

Okay, I read the wiki. My question is simple: why does Israel have the Right to "reclaim its historical territory," but the Muslim Brotherhood does NOT?!

If I were to continue this line of questioning, next would be: why does ANY religion have ANY right to wholely-rule ANY territory?

The "making us wait in the sun for an hour outside to board the plane" is to game the EU limitations on how long the airline can make you wait on the tarmac:

- after 1hr delay, they must provide access to water/A/C/heat/lavatories. Also to medical assistance (if needed). - and after 5hrs on tarmac, passengers must be given the chance to leave the aircraft. - Exceptions: These rules do not apply if the delay is due to safety, security, or ATC reasons.

Making you wait outside on the tarmac before boarding is bad but skirts the regulations. They key clock time to watch is how long were you waiting after boarding the plane?

Probably also useful to reference your specific EU rights if they object.

If after 1+1hrs wait, passengers were going to faint unless they got water, that seems to be pushing "would need medical assistance".

Agreed on most, and naming is terrible. Note that at run-time Python is out-of-the loop, since Newton Physics records a CUDA graph, and executes it, so performance is not impacted (aside from startup JIT time for modified kernels). I'd prefer C/C++ as well, and although you can call Warp-compiled kernels from C++ (without Python, see my https://github.com/erwincoumans/warp_cpp project), it would be better to have native C/C++ support without requiring a Python interpreter. It just happens that almost all Deep Learning/RL for robotics uses Python.

Yes, every gigantic new secret police force answerable only to the executive is created to "catch criminals" or "deport immigrants" or do whatever else people will accept, until said police force's mandate is morphed as needed. That is why so many 2A defenders are (rightly) skeptical of large domestic police forces answerable to the executive branch, which is what ICE is; it's also why so many defenders have been skeptical of the FBI, ATF, and so on. The only people who think the mandate won't adjust as needed are, to be blunt, trusting patsies, which is not what 2A defenders have historically been.

The creators and defenders of the second amendment were and are smart people. They were skeptical of highly concentrated power, which is why we have a federalist system; they were also highly skeptical of large concentrations of militarized police power, which is why our police in general are run by states and municipalities. It is really quite difficult to reconcile support of a massive ICE apparatus with any sort of comprehension of the political philosophy of the US constitution.

I've been self-hosting my email for over 10 years now (I'm going to link a bunch of my old comments on old email HN threads). I have fallen back to using Amazon's SES to send because all of Digital Ocean's IP blocks suddenly got marked as bad and I don't have enough volume to improve a new IP reputation - https://news.ycombinator.com/item?id=39891262, https://news.ycombinator.com/item?id=38471262

I use Gmail as a free spam harvester to train my own spam filter - https://news.ycombinator.com/item?id=38843288.

But as others here have suggested greylisting is extremely helpful in this space as legitimate servers should always retry. Well only my power company is the exception and they will fall back to sending paper bills, but even Gmail falls foul for them. It's also one big reason I'm not worried about up to a week downtime. But I have two email servers, a receiving and a storage server, the receiving is cattle and I car re-deploy in minutes if needed. - https://news.ycombinator.com/item?id=38512732

On greylisting I would say using https://github.com/stevejenkins/postwhite (even if it's very old and not actively maintained) has proven very important for the annoying 2FA emails, I strongly contend that email isn't suitable for this use case but that's another conversation)

"Just" is doing a lot of work there. Maybe the idea is reasonable, but the setup as-is is not safe, and there's nothing in the article that would tell you that, or tell you what you need to add to it to make it safe. Many people might read the article, think that it's all safe (because they don't have the knowledge required to properly evaluated it), and then burn their houses down.

Not saying this is the most unsafe thing I've ever seen or heard of, but we have electrical codes for a reason... because buildings have burned down and people have died.

Social Security data is mostly public information, de facto if not literally. Lexis-Nexis has effectively maintained a mirror of SSA for many decades that probably has higher data quality than the original. SSA inexplicably changed my basic immutable information many years ago but the process of getting it fixed is so onerous that I've basically given up at this point.

The amount of theater around Social Security numbers is baffling.

I perceive MS as just being in the "get people using it, accustomed to it, used to it, habituated to using it throughout their day" phase for the default free Win10/11 tier.

That little copilot icon is sitting there in the task tray, clickable and usable. I think people will, to whatever degree makes sense for them, get used to making some use of the basic free tier. Monetization / restrictions requiring some degree of limitations to upsell will eventually come for the currently half-billion or so Win11 users.

I get the point that few are currently paying for it, but there isn't all that much pressure to do so right now. That will come, later.

I'm not sure how many customers that Tiger Beetle have but I really hope they are successful. It would be great to see such a quality focused engineering org make it. They are basically doing what many devs really want to do - make the highest quality and fastest stuff possible - instead of banging out random features that usually no one actually cares about. I don't have a use case for their tech right now, but the moment I have a need for anything in the vicinity I'll be checking it out..

I at least maintain administrative control while using free resources. I looked at the completely self hosted route a long time ago and didn’t want to deal with that. Fast forward to today and I’m dealing with a friend who has the polar opposite. Now their mental faculties are reduced and they lost devices. Couple this with not paying previous management entities and it’s a digital lock out. Recovering from this is a nightmare and I’m operating blind. For a normie this would be impossible.

That's consistent with other research I've seen, where varied presentation of the data is key to effective knowledge injection [1].

My assumption, based on the research is that training on different prompts but the same answer gives you more robust Q&A behavior; training on variations of how to express the same concept generalizes. Training on the same prompt and different answers gives you creative diversity [2].

Most MCU-based keyboards have a 1000Hz polling rate - and some mainstream gamer-focused keyboards are even going for 8000Hz these days.

Getting rid of multiplexing is a result of having a high number of IO pins: an MCU like the STM32F429BE also has enough pin for direct-attach switches. Ghosting hasn't been an issue for ages, even with a traditional keyboard matrix it's just a matter of adding per-key diodes.

In theory it has a sliiightly lower latency than an MCU-based keyboard using the same USB interface, but I doubt the difference is big enough to even be measurable in real-world scenarios. We're talking about, at most, a few thousand cycles of an MCU running at a few hundred megahertz - and that's only relevant when you press the key right before a polling request arrives. That's the difference between an average input latency of 0.500 ms and 0.505 ms. Meanwhile on the output side, your fancy 480Hz monitor is only showing one frame every 2.1 milliseconds...

The power bill going up is because the US, and the West in general, bet on renewables and a low energy future.

Neither of those things turn out to be a good fit for the new economy. The only thing left for people who derided nuclear for the last 40 years is to hope this is a bubble that sends us back to the 17th century when it pops. Anything else means we have to invest trillions in nuclear right now.

$500K ARR often sounds more impressive than it is. How much of that is profit? Probably not much. Every SaaS startup I've worked for was bleeding money on cloud costs and employees.

Even after all the layoffs and cost-cutting one of them went through, the end result was mediocre paying jobs for a few people at most, with constant on call and fire fighting. One ended in a "acquisition", which was actually a pennies-on-the-dollar fire sale, with no payouts to the founder or any employees. The former CEO still talks up the big acquisition. It sounds like success if you ignore all the details.

The fact of their being lawless would preclude the argument. If the government is lawless then by definition they are not law enforcing. Not a government.

I don't see that remotely fitting the United States as a generalization.

I would argue that if you do, you are either poorly traveled, or fanatical.

I would hope it's the prior, for everyone's sake. Try hailing a cab at midnight in the middle of Mexico before declaring the US to be ultimately lawless.

Maybe don't actually try that.

Regardless if you find the government to be so unjust as to convince you to break laws and become violent, you belong in prison and the majority of people will help to put you there, make no mistake. Regardless of leadership, I highly value that about the US.

I hope you'll change your mind before that happens.

Boring is a short term thing - I think it's most useful to think about things like copilot AI for all windows users as a longer term initiative. Right now, I think MS is just letting people get used to a basic free tier. They will observe how Windows users put it to use, see to what degree of involvement people have with it, and evolve the product (and its pricing) from there.

Is it raking in cash right now? No. But that's just now. MS can and I feel is thinking longer term. Everyone is on a "Crash Dammit" Economist front-cover mode right, trying to will a crash into existence. Microsoft can think longer term about it - after all, we see younger generations diving in to make use of related technologies. Older demographics will, and are, slowly finding out what to make of the tech that is free with an OS install, and MS will see what kind of business to make out of that over time.

The problem with this broader topic is that people are restricting the time frame of the conversation to Right Now. MS doesn't need to worry about that so much, in the grand scheme of things.

Being extremely hasty with setting red lines and enforcing them is what got Israel into this situation. The "mow the lawn" strategy means perpetual conflict and they have to win every single time.

What right does Israel have to govern Iran's self defense capabilities? Iran's been attacked unprovoked by USA/Israel several times in the last 6-7 years, they're not the ones starting shooting wars.

Iran's supply chain is already fully domestic thanks to sanctions. Repeated strikes on that supply chain will only serve to harden it.

The problem is that it doesn’t actually do anything.

It’s “installed” at my company but basically refuses to interact with basic company data like files in sharepoint.

Is it the IT department’s fault for not enabling something? I don’t know, but does that matter?

If the normal search system has access to the data why doesn’t copilot? Surely it would be trivial for Microsoft to run copilot in a way that keeps company data private so that they could actually turn it on and make it useful by default.

For some, but what about the others? The reddit mentality of "everyone hates LLM AI tools" is just a very loud segment. What about everyone else? What about a random Joe who asks it questions to find some path through figuring out why their computer is acting all wonky? What about the people who don't know the first thing about dealing with their water heater suddenly going south, and ask it some basic questions of how to approach that problem? That is, treating it as an OS-native improvement over a search engine.

The list goes on and on, and we have to take time into consideration: people may have default strong feelings against the tech in question now, but often that's just a default stance. Over time, people will dip their toes in, and make use of it to whatever degree makes sense for them. Don't mistake current vocal criticism for the end all, be all, stance that will last forever: people get used to stuff, use it a bit, or more than a bit, time passes, and the tech slowly melds itself into people's lives in some manner and in some form: MS will wait and observer, and evolve the product to suit that slow change over time.

It’s because companies deliberately make the privacy option constant friction. When the options are “yes” and “ask me again repeatedly” it’s not surprising people eventually give up and just say yes to everything.

It needs to be part of the law that companies are simply not allowed to abuse your data like they are currently. The GDPR was a good start, but it needs to keep going much further.
