While I agree with the title of the article, some of the contents seem a little over the top in the way they present them. We would need to see the document to know how bad it really is. Many of the failure modes could be user dependent for lack of training (ie finger in trigger guard when holstering). They also don't say which failure modes were fixed and what remained. That said, all you need is one valid failure mode to be dangerous.

"Sig Sauer also stated that the manual safeties on M17 and M18 pistols would resolve some of the issues,"

This would only be the training dependent ones. Mechanically, the safety only blocks the trigger and does nothing to block the striker or sear.

Without seeing the full experiment and data its hard to tell, sort of like guessing why a soup tastes bad without trying it but here's my guesses!

1. Good instinct with LORA and PEFT. As others suggested below perhaps try changing the hypers, either making the LORA adapter bigger, a higher learning rate, or using more epochs. See where things start to shift from "nothing" to closer to what you want

2. For full finetune track earlier checkpoints to see where the forgetting is happening. So for instance if you're training for 1000 steps, check step 100, 200, 300, etc. You'll see where the shift starts to happen and where it becomes too much. Here is an example where you can see where the LLM starts to pick up "words" then sentences, as it goes through training https://ravinkumar.com/GenAiGuidebook/deepdive/GPTFromScratc...

3. Use smaller models for testing before moving up. Part of the reason we released this small Gemma is to support the larger Gemma models as well. Testing changes on small models lets you more quickly and cheaply see whats working and isn't, before then scaling up to fine tuning the bigger models.

Hope these tips help and thanks for using LLMs for localization and what sounds like tasks to help your specific community, and sharing here. It's personally motivating for me to hear that people are using technology in this way.

This very afternoon I coded with ChatGPT what would have taken me maybe some more time. Maybe 30-50% more. True that it was more-or-less independent code.

I think these tools are very effective at four things:

1. initial scaffolding (and isolated scripts also) 2. reviewing code and finding insights of where an error that we humans are very bad at spotting could be, given a description and an area of code. 3. If you are not an expert in something (for me that is frontend) it helps. 4. finding ideas on how to approach a problem through a conversation

But if you are well-versed, you still have more context and better decision making. They are ok-ish but not expert level.

It also comes with downsides if you abuse them: you could end up not understanding your codebases well enough or adding bad quality code that seems to work.

Also, if you initially think you can solve a problem with AI and it leads you the bad way, you end up wasting more time than what you save.

All in all, I find them good at scaffolding, asking ideas or solutions and spotting potential bugs.

As a whole they are accelerators but not replacements, IMHO.

Private companies spending (and potentially wasting) money investors voluntarily gave them because they think it may lead to a big payoff down the road is capitalism.

Companies doing the "same thing" with government handouts (where the ultimate source of the money had no say in the matter) is not.

It's like the difference between companies that hire workers and those that use slave labor. They may have otherwise identical business models, but the later are operating at an unfair advantage.

I'd like to see add on study on 'Banality of Evil'.

Here "The willingness of those in power to act fairly depends on how easily others can collectively push back against unfair treatment, psychologists have found."

What about all the the middle managers that enable the powerful.

The more the middle layer of population supports the powerful, the less the 'masses' can revolt to enforce fairness.

All revolutions are actually started by the middle class which gets upset. The true lower class masses never have the resources to get off the ground.

And the worst part is that they don’t perceive the massive irony of posting these comments on this particular medium, the Internet, which was initially the product of a military-funded project of the most capitalistic country in history. A project which aimed to deliver a resilient communication network in case of all-out nuclear war!

Most of the people who comment like this most likely have lived since birth in a stable, western democracy with social and economic security and they don’t know anything else. They don’t know what living in a dictatorship is like, or under a fully corrupt government bureaucracy where only nepotism or favoritism gets you ahead. All they’ve known is their little, stable corner of the world, protected by the largest military and economic powerhouse in history, and they don’t appreciate it.

In a nutshell, the defect that causes the guns to fire when holstered occurs when there is a small amount of pressure on the trigger. If the slide (top part of the gun) is wiggled / nudged, it will fire. Also, the gun can fire when dropped. Both these issues are mitigated by other manufacturers with a trigger safety and longer trigger pull.

All of Open Source needs a sunlit patent pool, a searchable database of documented inventions AND all of the follow on ideas around them. This could provide a way to force patent examiners to do their jobs and allow the Open Source Community to crowd source invention bombing the proprietary world.

How does one lookup these patents? They need more exposure so they can be refuted.

Ask yourself why? is it because something is broken and you think this will fix it? that’s the classic empathy narrative which I guarantee is actually nothing but envy masquerading as empathy.

>Both these issues are mitigated by other manufacturers with a trigger safety and longer trigger pull.

And just not having hot dog down a hallway tolerances at the slide to frame interface.

The trigger stuff lives in the bottom half of the gun and the bang stuff lives in the top half and only goes bang depending upon the relative position of the trigger stuff. So allowing the top half and the bottom half to move around a ton is generally unwise unless you make accommodations elsewhere in the design so that you still have proper relative position regardless of where in the hallway the hotdog is.

Uh yeah? Prusa Mini has his face as boot screen. Cannot find any ref’s online sadly (I sold the printer). Edit 1: speaking from a Prusa perspective I guess..

Edit 2: wait, i misunderstood ‘you cant be serious’? Not sure but what I tried to address was a cult of personality. Thats not something I feel fitting in this whole context.

That's very reductive. Famously Switzerland has difficult terrain and many of the large infrastructure projects happen in the alpine region. Some of those projects are quite challenging and require international effort and coordination. GDP per capita being higher is an advantage, but it also makes everything more expensive domestically.

The approach outlined in the article, is also not applied generally to all infrastructure projects. It's specific to transport. It works because the process is sound and long-term oriented and not because Switzerland is small and rich. Perhaps your comment even inverts the causality.

TFA didn't really make the problem clear to me. I think it something like this, but I'm not sure. Can anybody clarify?

Problem (?): We can't produce open hardware for things that others have patented. Chinese companies (and maybe others) are patenting lots of things, including things we might have ourselves developed and intended to keep open, so it makes it difficult and/or expensive for us to continue developing.

Is that it?

> In a just society they would be, but we have ceased to be a just society for the last 50 years.

When did we start being a just society would you say? WWI? The Civil Rights Act? Unless you really stretch things, saying that justice declined in the last 50 years - even if true - means that justice "peaked" for a short period of maybe a generation. I suspect if you actually lived in that era[1] you wouldn't think that though so this whole framing is based on false nostalgia for a time you never experienced.

Also partially subsidized by the government, who charged their mom-and-pop brick and mortar competitors sales tax while Amazon avoided subjecting their customers to sales tax for many years. That, plus Amazon's ability to operate at a seemingly perpetual loss, was absolutely predatory.

And the government sat on its hands and our representatives loved all the Prime boxes stacked at their doorstep. It has ensh#ttified entire industries that once depended upon retail as their interface with customers.

Right. The big lie of what's called Our Democracy (in the US, UK, and other Western nations) is that having 51% on your side and winning elections means you get some control over government. What recent years have made clear is that the bureaucratic class does what it wants, and resists most attempts by the people to control it through their representatives, using its media wing to call those anti-democratic and other epithets. At best, you can make temporary changes that the machine will roll back as soon as it can get rid of your representatives.

> What makes you think these things aren’t subsidized?

You can pay Amazon or a great many other hosting providers for inference for a wide variety of models. Do you think all of these hosting providers are burning money for you, when it’s not even their model and they have no lock-in?

> It would be very impressive if Claude was making money off of their $20/month users that hit their weekly limits.

They have been adjusting their limits frequently, and those whole point of those limits is to control the cost of servicing those users.

Also:

> Unit economics of LLM APIs

> As of June 2024, OpenAI's API was very likely profitable, with surprisingly high margins. Our median estimate for gross margin (not including model training costs or employee salaries) was 75%.

> Once all traffic switches over to the new August GPT-4o model and pricing, OpenAI plausibly still will have a healthy profit margin. Our median estimate for the profit margin is 55%.

Chinese stuff these days has pulled far ahead of the Harbor Freight reputation of my youth. I can't remember the last time I've seen a proper "Engrish" instruction manual, most of the things are well designed and well built. Meanwhile, the "good old American brands" seem to just be selling out for cheaper and better profit margin products, so you'll be ending up with Chinese stuff anyways, which is sometimes worse than the actual Chinese brands.

By today's standards, mass rapes against german civilian women by the soviet army and other allied forces[0] or bombing of various cities of no industrial importance, such as Dresden would be easily considered as war crimes.

Saying "but they were nazis" is no different that when the Hamas explains that every Israeli civilian is a soldier to justify their actions.

Is there a name that these upscaled releases fall under to easily find them?

Star Trek in particular (I was watching voyager yesterday) the quality is always pretty depressing when shown on a larger TV. Been recently thinking about trying to find the best quality I can find but it is always a lot of trial and error. But if there is a common name and tag I could look for that would be great.
by vidarh | 2025-08-15 13:28:18+00:00
I wish it wasn't like that, but the position isn't hypocritical:

You're free to complete saying something unlawful because until you've said something unlawful you haven't committed a crime, but furthermore, English law on what is "unlawful" to say or do is also complicated in that many things are okay to say or do in contexts where they will not cause offence but becomes illegal if done in front of the "wrong" people or with the "wrong" intent.

As such, until there has been a complaint there often will not be a basis for saying that something was unlawful to say unless it is really far over the line.

If you were to start shouting something blatantly illegal such as chanting support for a proscribed organisation, you must certainly would not find police standing there and waiting unless they deemed it likely to be more disruptive to peace and order to stop you right away.

This expends past speech - e.g. public nudity is in the same category that isn't illegal in itself but where intent or the effect on others can make it unlawful - and this notion on relying on intent and whether or not someone present took offense rather than clearly delineating where the boundary is, is a challenge with English law because of the huge gray areas it creates.

[used "English law" as shorthand here - really it is the law of England & Wales, and much of it will be the same in Scotland, but Scotland does have a separate legal system, hence why it isn't "UK law"]

> Injection molding is very expensive and hard to do in the basement

You can make everything in your basement, just like you can make a 3d printer in your basement, and for similar prices. Almost nobody does it, but that doesn't mean it can't be done.

> Wood working too, requires lots of time, skills and many tools...

Skill is developed. You can do woodworking with just a sharp rock you find, no need for any more tools. Most people in woodworking choose to trade money for time and buy a lot of tools, but you can decide how far you want to go.

Time is the real constraint for everything of course. However that is my original point - if your goal isn't building a 3d printer (a fine goal) then trading money for time and buying the tools (which might or might not be a 3d printer) is probably you best bet. Assuming you have money to buy a 3d printer of course, but if you don't than a sharp rock and woodworking is probably your best hobby just because it is what you can afford.

Congrats on the launch! I've tried building a windows automation script myself but found existing solutions quite cumbersome booking appointments and fetching information on a desktop SMS.

Can I monitor/manage this remotely? I'm not on site with the client and previously tried to manage through AnyDesk but the client often turned off the machine.

Also is there anyway to run this so that it won't interrupt workflows while someone is using the machine? I imagine a solution could just be having the client run an extra computer that's dedicated for this or running after hours on the local machine.

I find the car = gun analogy so tired. A car's purpose is to transport, and sometimes it accidentally kills. A gun's purpose is to kill. People always say "it's a tool"... yeah, to kill. Anytime you have a device like that, unexpected killings can happen. People shoot themselves and other people accidentally all the time; not because it was not "used as intended", but because it's a killing device.
Show HN: Hero 2.0 – Notion for formal docs
by kevintouati | 2025-08-15 13:29:13+00:00
Hey HN!

We just launched HERO 2.0 - collaborative workspace combining the flexibility of text, the structure of databases and the power of integrations.

It's built for teams who write formal, structured documents like legal contracts, technical specs, SOPs, and policies.

This project is the result of many years acting as corporate lawyer and mega-project specialist, navigating through the maze of complex, high-stakes, structure-heavy & interconnected documents - overlapping the legal, financial and technical.

It's all about bridging the disconnect between transactional teams and operational ones.

You can try it now at [myhero.so](http://myhero.so/) and let us know what you think!

Best,

The HERO Team

There are videos online showing that this also happens with Glocks (when the trigger is depressed to the wall) [0]

Really, any gun where the sear is in the grip and the part it connects to is in the frame could have the same issue.

Also, they’ve had numerous issues with their triggers failing to reset correctly and/or otherwise misbehaving. That was the focus of the original ‘voluntary upgrade’.

That this giant mess of bad tolerances, sloppy change management, iffy manufacturing outsourcing, and a design which is sensitive to these issues it seems inevitable these kinds of random and hard to reproduce problems would occur. And the more they sold, the worse it would get.

Do that in something which literally can cause death and serious injury if it fails, in an environment where all your competitors designs don’t have these issues and hence users tend towards ‘round in the chamber’ and carrying them in all sorts of messy real world situations? Guaranteed disaster eventually.

Bad sig.

The brand was dead to me many years ago (extractor snapped in the middle of a course - seemed like bad metallurgy, or a bad design), but this is entirely another level of crazy.

Thanks for checking out HERO 2.0! I’d love feedback on two areas in particular:

1. Structure vs. Flexibility – One of our core design choices is keeping strict document hierarchies (sections, clauses, schedules) while still allowing flexible, free-form editing. Do you think this helps or hurts for high-complexity docs?

2. AI Workflows – We’re experimenting with AI tools that can draft clauses, check consistency, and update terms across multiple linked docs in real time. If you’ve tried similar tools, what’s worked well and what’s been a miss?

Also curious: if you currently use Notion, Google Docs, or Word for legal/technical/SOP writing, what’s the biggest pain point you’d want solved?

I’ll be answering questions throughout the day — really appreciate any thoughts, ideas, or even brutal critiques.

Prusa makes their products locally, the spare part situation is good, the company runs an open Makerspace in their basement, helps host conferences and has done a lot for Open Hardware in general. They also have offered consistent upgrade paths for old machines for a long time and the repairability in general is good. You can also talk to them. These things matter for purchase decisions. Same logic as per your Knipex and Wera example.

I actually have a Bambu Labs at home for occasional use but I would not consider anything but Prusas for a general-use desktop FDM printer in basically any more serious setting. This has been the situation for many years now (over the last 12 years or so, I've had to make a few purchase decisions for batches of 5-15 FDM printers as well as different single specialty ones).

It is annoying, I would much rather pay for the content I am consuming since I want to support content being made.

But with prices going up and there now being so many services, I find it hard to justify more than a couple.

I pay for Apple TV+ and Disney+ with zero hesitation since I get a large amount of content from both of those that I actually enjoy. I added Hulu to Disney plus because why not.

Outside of that I just can't bring myself to subscribe to Netflix, whatever HBO is calling themselves now, paramount, etc etc anymore. It added up too quickly and there are alternative solutions.

It isn't even necessarily about the cost anymore; I have spent way too much on the hardware for my media server and I am nowhere near any concept of breaking even. But I no longer need to think about where something may be accessible just to be disappointed that I can't stream it.

The reason they can’t fix these issues is someone in leadership likely literally has Narcissistic Personality Disorder, and is quite literally incapable of acknowledging a mistake or problem. To the point they’ll inevitably torpedo the company rather than take any ownership or responsibility.

If the Board is smart, they’ll fire the person before it gets to that point - but if they were smart, they probably wouldn’t have hired the type of person to get them into this mess in the first place.

I haven’t read Discworld. Although funnily enough I worked in a team where our services were named after Discworld characters, so I’m aware of _some_ lore lol.

That said.. it’s kind of daunting to start a series with so many books, and I consider myself a prolific reader (~30-40 books per year).

I don't see how that could be considered a planned economy, you're describing individuals creating startups of their own free choice and the government backing them with no strings. Individual choices are driving economic progress.

A planned economy would be some government committee deciding what specific startups and how many of them should be started up in any give year, and no one else can create a startup.
