I think the "printegrated circuits" approach is roughly the right level of abstraction.

3D Printing the PCB itself is pretty much impossible for any non-trivial application. Doing multi-layer PCBs with 0.20mm wide traces, spaced 0.20mm apart? Forget it, not happening - and requirements like those are standard for hobbyist-level chips like the RP2040 these days.

And if you're not printing your own PCB, what's left is module-level assembly and connectivity. In other words, just printing a bunch of wires.

You seem to be getting wrapped around the axle (ha) to have an argument and not reading my point well.

>having more complicated and less reliable components anywhere in the system makes the whole system less reliable.

This is my entire point, because the hybrid has many of the same components. Yet you get focused on individual components like transmissions instead of elaborating on the system reliability. I’ll concede that the hybrid ICE may be more reliable (that’s what I meant by asking you to provide details why the ICE is more reliable). But my point is that a more complicated system in series requires all components to be substantially more reliable to have an overall equivalent system reliability.

Consider the life of a traditional ICE engine is about the same as the batteries of a hybrid. Even if the hybrid ICE has a life 30% longer, it doesn’t make the overall system last longer. For round numbers, say the traditional ICE and hybrid batteries have a 200k mile median life (50% reliability).

That means the combined (series) R(hybrid ICE) * R(planetary gears) * R(hybrid electric motors) has to be greater than R(traditional transmission). Maybe that’s the case, and I’m asking for details and specifics.

Now obviously, it’s more complicated because there are other failure modes in each system and cost differentials as well. From the get-go, you seemed focused on individual component reliability. But unless you’re talking specifics about the system reliability you’re tilting at windmills.

> Oh, certainly! But it needn't be exclusive. (And "teach people better" is a lot harder than running a wire to a $30 camera.)

But earlier you were pretending that it was the case. Interesting.

Do you not remember?

> I'm glad I can both survive a rear-end crash and being reversed over by someone driving a Hummer with a six foot high blind spot in the back. I don't have to pick one improvement, which is great.

Are you saying the mandated camera doesn't stop someone from reversing over you or that the hummer doesn't have the camera, but won't kill you because the camera is mandated by law in other vehicles?

I am not sure what to make of this statement.

> Reducing this to the naturalistic fallacy is inappropriate.

> Notice the commenter said "most likely". He's using a heuristic.

They are using a purely appeal-to-nature-and-antiquity-without-any-other-justification heuristic. If your objection is that I should have said "appeal to nature and antiquity without any other justification" because you think "naturalistic fallacy" means something else (which it might), then ok let's go with that, but otherwise it's very appropriate.

"Most" likely is a decision about the balance of merit.

Show something beyond "people did it without chemical analysis" that doing one is actually better than doing the other, especially in the way being discussed by the article. Show that rubbing olive oil on your body won't likewise disrupt your oxidation field. Show that the polycyclic aromatic hydrocarbons in olive oil aren't individually disruptive to skin chemistry despite suspected or known links to cancers, cardiovascular disease, and poor fetal development.

> He said they got "some" things right. It's implied that they got a lot of other things wrong.

Picking which things were right and which ones were wrong requires analysis of the merits. They did none of that.

ps. Do we have a reason to call them "he"? I didn't see anything in their profile or comment history.

https://procgenzoo.com/ (currently not deployed)

Elevator pitch is: A simple searchable directory of various procedurally generated toys. Think Boids, Game of life, Maze generation, terrain generation, etc. written in Ts/Js. Anyone can contribute and will get their page for their implementation of a given ProcGen.

This is optimized for

1. Hobbyists wanting to make a ProcGen and have it be publicly available

2. Game Dev's & Academics looking for inspiration

3. Students / Amateurs looking for a project to add to their portfolio. It's specifically aimed at making the barrier of entry for your first "out-in-the-world project" as low as possible.

Long term vision will include bounties i.e. "I'm looking for a terrain generation algo that makes one main island surrounded by 6-12 smaller islands, some connected by a bridge, and every island should have an organic coast line with coves & bays and stuff".

There will be a voting system so clean, polished, well documented implementations of a given algorithm float to the top, (i.e. Game of Life) might get procgenzoo.com/CellularAutomata/GameOfLife.

The plan is to keep this free forever, and hoping donations cover hosting fees.

I'm also working on BackPackReact. Which is an inventory management game where the placement of various components inside yourback will create & consume resources to power your jorney to the next trading post. I.e. Fire/{HeatSource} and Ice/{ColdSource} on either side of Thermoelectric Generator will generate Power, which enables your vehicle to keep moving.

But it's a balancing game, the more space you use for your machinery, the less space you have for inventory for your cargo. You want the most efficient "engine" but also enough supplies to handle any unexpected events.

Is it better to build a nuclear reactor? Or just fill up on wheat and rent & feed a horse to pull you to the town, so you can sell all excess wheat you didn't use? Should you spend money to gather intel on the trading price of Iron is at your destination city? Or pick up a contract to build an electric grid at the new settlement, which will require many trips but yield one large payout?

---

Would love feedback on either of these ideas :) & if you would contribute to or play either.

I've used ChatGPT almost daily for months. It has never said anything like "I've seen whispers, posts buried in niche communities..." as though it's some kind of secret agent. And if it did, I would ask for the links. I'm not sure what "Sage" is, but it seems like it has been trained to respond as though it is a character in a spy thriller, addressing the fictional protagonist for maximal dramatic effect.

WARP is a full VPN tunnel. The above poster was suggesting if someone wanted to avoid a VPN tunnel, DNS64+NAT64 is a nice "hack" that just uses DNS as the tool to reestablish IPv4 connectivity. (It's also how most mobile/cell traffic today reaches IPv4, via DNS64+NAT64 gateways.)

You've hit on the core. We don't manually tweak sigma directly in operation. Instead, sigma_threshold is a high-level cognitive trait. The beauty lies in the system's inherent drive for realignment: even from random initializations, PILF converges by minimizing surprise. With G²MoE in future, the model will gains the theoretical capacity to self-adjust its own hyperparameters, akin to a more fundamental Gödel Agent.[^1]

Ultimately, wallet balance is the true ultimate hyperparameter.

Google maps marks data out of typical traffic for that day and time in the week, basically meaning that if on a Thursday, at 3 pm, there is a wait time reported of 2 hours, where there is typically a reported wait time of 30 minutes during that same weekday and time, then it is marked as above usual traffic (and there are other factors google marks data with - a larger range than just saying "above usual traffic").

Hardly. Just that "teach people" is tough, expensive, and time consuming. "Install a $30 device" is not. (In your now flagged last-last-last reply to me, you advocated for PSAs. As we all know, they worked great to stop texting while driving!)

> Are you saying the mandated camera doesn't stop someone from reversing over you or that the hummer doesn't have the camera and the hummer won't kill you because the camera is mandated by law.

I'm saying I'm glad the Hummers now have backup cameras, because they sure as shit can't see me with the windows/mirrors.

I started reading this to understand Open Bus, which was capitalized in the title, so I assumed it was a proper name for some old bus protocol/standard that I'd never heard of.

After reading, I realized that he just meant that the bus was "open" as in not connected to anything, because the address line decoders had no memory devices enabled at the specified address ($2000).

It's pretty funny that the omission of the immediate mode (#) went unnoticed until the obsolete emulator didn't behave in the same way as the real hardware when reading <nothing> from memory.

His solution of changing the instruction to use immediate addressing mode (instead of absolute) would have the consequence of faster execution time, because the code is no longer executing a read from memory. It's probably now faster by about 2us through that blob of code, but maybe this only matters on bare metal and not the emulator, which is probably not time-perfect anyway.

Apple has previously said they want a large user base (hence why they are giving upcoming OS26 to older devices) as they are seeking to maximise the sales of software, accessories and subscriptions.

The more apple devices in circulation, the more 30% cut from App Store, Ai Services, apple TV, music,games, earbuds and everything else.

They are now like a video games console maker selling games and accessories, except unlike console makers, they don't sell the device for an initial loss but profit.

Hey, I was actually in this position at work a few years ago, when I set up a couple of internal (monitoring stuff) servers for my own use. I used Let's Encrypt, because I use them (for free) at home (media server), and know how it works.

I wanted to throw them some (of work's) cash, and... the only two options were "Sponsor", and "Donate". Sponsorship was, uh, wrong for my use-case: it starts at some multiple-thousands of dollars. Donating would be the obviously correct choice, but putting something marked "donation" onto a corporate card would occasion a... Weird conversation, in which "you could have got this for free, but you're choosing to send them money?" would likely have been raised. I went with free, and was sad about it.

Yes, corporate expectations and affordances around FOSS should change - and, I probably could have persuaded my employer that a few dollars a month for Let's Encrypt was the Right Thing To Do, so I'm a little bit of a coward - but LE would make it so much easier if there was a Send Us Money option that looks like a fee for service, rather than a donation. (Maybe being a 501c(3) precludes that? I don't know.)

There's the "Corporate doesn't understand FOSS" problem, but there's also a "FOSS doesn't speak Corporatese" obstacle there, too.

In the end I sent LE $20, or something, of my own money (I've had years of trouble-free use on my media server, and should have before), but they'd have had $5 / month of work's cash for years if they'd made that easier to do.

It does more than you think it does. GitHub may not support IPv6 and Apple can't force them, too, but the GitHub App on iOS is in most cases using DNS64 to get an IPv6 address to a NAT64 gateway to the GitHub IPv4 addresses, and all that just works today, in part because Apple forced apps to support "I'm always going to give you an IPv6 address, even if you know your own service isn't going to naturally return one".

Is this solving a real problem?

A radar suitable for a small port or harbour is not particularly expensive. You can pick up a very nice complete system for ~$5k, a budget system is ~$2k.

Does this system cost less than that (I can't realistically see how), while providing coverage as good as a purpose built marine radar? What happens if your passive signal source goes down.

I ran into a similar issue a long time ago, with the GNU assembler in "intel_syntax noprefix" mode. It has an issue where there's syntactic ambiguity that makes it possible to interpret a forward-referenced named constant immediate as a reference to an unknown symbol, if in an instruction that could accept either an immediate or a memory address. The net result is assembling the instruction to have a placeholder memory address (expected to be filled in by the relocated address of the symbol when linked) rather than the expected immediate. Painful to debug.

As I recall, the faceted look of the early stealth aircraft was said to be a practical matter. It reduced the complexity of modeling the reflections during the design process. So with additional computational complexity, they could go back to smooth surfaces in later designs.

I imagine there are similar issues with ship design. Since these things are wavelength specific, you probably have a bigger computational problem for a bigger vessel. You can't just solve for the design on a miniature and scale it up to build it.

As a kid, the first text adventure I encountered with "The Cave" a text-choice game created by another student in the same town I lived. Our common teacher had created a "Computer Club" newsletter, to share programs between schools.

Then at a junior college I encountered Adventure, Zork (the full version), Mystery Mansion, and Warp on an HP 3000/terminal mini-computer system.

I began writing text adventures myself, bigger and bigger, and with higher and higher ambitions in terms of complexity, story and world scope, parsing. My "Command English" parser was an incredibly versatile subset of English.

At home I had an IBM Jr (Hey, I loved it!), whose BASIC didn't have GOSUB, so I invented a stack for the parser using strings. (Used strings as a heap in another program to create a very slow 3D vector graphics program.)

In high school I wrote this massive text adventure called Wanderer. I was so proud of it, until the day I went to save it on my floppy disk, at which time it wrote all over the previous version only to abort because it was to big for the disk. No pre-write size check! :(

That was the last one I wrote. But by pushing every text adventure to new levels of capability, over and over, I learned a lot about programming, and developed a habit of innovating in program styles, and domain languages, to match problems.

I wish I had the source for all those programs, but these were the days of many incompatible computers, and storage media that decayed quickly.

---

I would love a Mac version of those four text adventures mentioned above. Mystery Mansion seems to have become particularly forgotten.

---

"The Plot of the Phantom" makes me so happy! Thank you Scott Andrew!!!

(Completely random, but reading the opening scene, it struck me how perverse it would be to get deeply into the game and find out I was in the text adventure equivalent of "Deliverance"! That would almost be art, lol. Like novels, text adventures are a medium that naturally supports much greater freedom, than visual mediums.)

I love word games. My day starts with Wordle and Spelling Bee. I have been looking for something to work on with AI. I have watched the videos and read the articles and used Claude to help figure out issues with another app I'm working on. I came up with Letter Lockbox [https://www.letterlockbox.com]. It started as something fun to play around with but friends and family love it so I have been adding on to it as I go. I added a Postgres database and Clerk for user management so users can save their results. I added streaks, stats, and sharing. I built out my own admin area to allow easier adding of puzzles and analytics on game play. I'm really proud of it.

Comcast has no phone option, unless you are canceling service.

Calling their support line gives you repeated prompts for talking to their chat bot. If you say No enough times, it just texts you a link to the chatbot anyways and disconnects the call. Because fuck you!

Ask HN: Safe Fundraising for Hardware Startup
by eggy | 2025-06-30 16:27:42+00:00
Curious if any HN folk are familiar with SAFE agreements for physical, more industrial startup products. We've designed and engineered, and we have a working prototype for a very unique hoist. I am programming the control system in Ada/SPARK2014 to achieve above-standard safety certifications. We are a couple of techies, mechanical engineers, who have been in the entertainment business for decades. We had a few friends get us off the ground with a modest investment, but we now want to take it to the next level. Can anyone recommend a startup accountant/lawyer in the NY/NJ area? We had an old friend, a CPA, but he was a forensic accountant, and not really versed in startups and bringing products to market. Thanks for any advice or leads you may have!

https://github.com/thiagoharry/weaver-interface-metafont

I started by trying to reimplement the METAFONT language, adding support for real-time rendering with OpenGL. Eventually, I decided to introduce some incompatible changes, creating a new language. But it still retains a syntax and internal logic very similar to METAFONT.

This new language also supports animation, and since it is part of a larger project (a game engine), it can be used not only for font rendering but also to generate textures and sprites for games.

The language is successfully compiling to WebAssembly, and I’m currently working on a web page with tutorials, documentation and examples where you can modify the code and instantly see the results. Since this is a literate programming project, there is also an English and Portuguese version of the code. But the english version still needs considerable polishing.

> This is my entire point, because the hybrid has many of the same components.

So we both agree, a hybrid and a full-ICE will have many of the same components overall. They both need a battery. They both need some kind of transmission. They both need some kind of inverter. They will both have some kind of electric motor in them. In terms of actual number of components, the hybrid and the ICE are actually pretty similar.

But then we both agree, some of those components in the pure ICE are far more mechanically complicated. Higher mechanical complexity, more moving parts, etc generally means less reliability, agree? And one part of that system being radically less reliable makes the whole system less reliable, correct?

> That means the combined (series) R(hybrid ICE) * R(planetary gears) * R(hybrid electric motors) has to be greater than R(traditional transmission).

No, your math would that for the pure ICE would be R(gas ICE) * R(traditional transmission). Your ICE car isn't going to go very far without a motor to spin the transmission. And that traditional transmission is far less reliable than the fixed planetary gears. Comparatively, electric motors are extremely reliable, and chances are your hybrid gas motor will be more reliable for the same kind of required output. So, R(hybrid ICE) > R(gas ICE).

So yes, generally speaking R(hybrid ICE) * R(planetary gears) * R(hybrid electric motors) > R(gas ICE) * R(traditional transmission). Largely because that R(traditional transmission) is so absolutely terrible in comparison to R(planetary gears) * R(hybrid electric motor). Which is why I'm talking about the transmissions so much, and yet you're continuing to ignore it.

I guess it's not ENTIRELY a favor since I founded that company but stepped away a few years back and always felt a bit guilty ever since. They certainly weren't expecting me to build it though.

I built it all myself (including the integration with our ordering platform) It was sort of my white whale project that I've always wanted to do but didn't have the chops/time.

The advancements in AI-assisted coding encouraged me to give it a shot though and the results turned out great. It was a heavily supervised vibe-coding project that turned into a production-ready system.

I’m working on a help center that keeps itself up-to-date - https://happysupport.ai (landing page is German, product is English)

Creating and maintaining an up-to-date help center is a huge hassle. In many companies there is no one that really feels obligated to take care of it.

We want to optimize this process:

- Creation: Just click through your process. We take a screenshot on every click and generate a full written article with screenshots and a GIF. You can also talk while recording to add additional context.

- Maintenance: Connect to your tools (GitHub, Asana, Slack, …) and we automatically suggest changes to your docs if your product changes.

- Consumption: Users can consume the content as they like: Read the docs themselves or ask a Q&A bot.

At the moment the creation and consumption parts are already working well. Now I’m working on the maintenance part.

We've worked with telecom teams who spend 30–40% of their time doing manual data updates across OSS — GIS, NMS, inventory, etc. This article breaks down the cost, the risks, and examples of service failures.

It also shares what a modern OSS system (like VC4’s S2C) does differently — including live data reconciliation, GIS with signal logic, and no-code provisioning.

Curious if other engineers or network ops teams have dealt with similar issues — would love feedback.
