What concerns me most in the era of gen AI irt photography is journalism. We need truth, most especially when limited-means citizen journalism is the only reliable source of that truth.

But I feel like the only way to accomplish fool-proof photos we can trust in a trustless way (i.e. without relying on e.g. the Press Association to vet) is to utterly PACK the hardware with sensors and tamper-proof attestation so the capture can’t be plausibly faked: multi-spectral (RGB + IR + UV) imaging, depth/LiDAR, stereo cameras, PRNU fingerprinting, IMU motion data, secure GPS with attested fix, a hardware clock and secure element for signing, ambient audio, lens telemetry, environmental sensors (temperature, barometer, humidity, light spectrum) — all wrapped in cryptographic proofs that bind these readings to the pixels.

In the meantime however, I'd trust a 360deg go-pro with some kind of signature of manafacture. OR just a LOT of people taking photos in a given vicinity. Hard to fake that.

I've known kepano (their CEO) for almost 20 years, he is an incredible builder and a solid human. My hunch is they would never act in an unsavory way to their users. I get that the point it could be more open (a community build would be slick), and yet it's an incredible product and worthy of financial support. I am glad to be a user and love that it's a part of my daily workflow.

You can programmatically remove the watermark, either via a flag or by changing the source code.

> [1] No, you can do whatever you want with it since it’s MIT

But if you use it in a commercial project, they'll likely shame you if you don't pay - like what happened to OpenAI with Agent Builder:

> [2] Hey @OpenAI :) We just saw that you are using our open source library React Flow We offer startup discount codes :) Let us know if you are interested

Personally, I’d prefer them to use a dual license, but I understand that it would likely create unnecessary hurdles for devs who just want to try out the library.

I think you can either have the memory on or off but according to the docs the projects have their own separate memory so it wont leak across the projects or from non-project chats:

"Each project has its own separate memory space and dedicated project summary, so the context within each of your projects is focused, relevant, and separate from other projects or non-project chats."

> I wish John McCain was still around... he would have had the courage to stand up and talk sense into these people.

At one point I would have agreed, but then in 2017, McCain made his "We will regret what we are about to do" speech before the R's removed the filibuster requirement for the Gorsuch confirmation. And as an Arizona voter, I switched my registration from Independent to Democrat.

> “I fear that someday we will regret what we are about to do. In fact, I am confident we will,” said Sen. John McCain, R-Ariz. “It is imperative we have a functioning Senate where the rights of the minority are protected regardless of which party is in power at the time.” > > Nonetheless, McCain voted with McConnell on the rules change, saying he felt he had no choice.

Back in college (~2008) we implemented this with a 7 foot tall back-projected screen and a couple of Wii remotes after seeing Johnny Lee’s video. The nice thing with that screen was that you could stand so close to it you couldn’t really see the edges.

We had as many people come test as we could, and we found that 90% of them didn’t get a sense of depth, likely because it lacked stereo-vision cues. It only worked for folks with some form of monocular vision, incl myself, who were used to relying primarily on other cues like parallax.

Seems to me that a camera like this is necessarily, at least in part, a closed system that blocks you from controlling the software or hardware on the device you supposedly own. It's hard for me to think this is a good direction. And as others have pointed out, it can't prevent attacks through the analog hole, e.g. photographing a display.

It's not feasible or desirable for our hardware devices to verify the information they record autonomously. A real solution to the problem of attribution in the age of AI must be based on reputation. People should be able to vouch for information in verifiable ways with consequences for being untrustworthy.

> The cost of mounting solar panels nowadays is often higher than the cost of the panels.

This fact always surprises me. What goes into a mount that makes it so expensive? Its essentially just a piece of metal, right?

The article goes into the parts for their custom fence project, but for the more typical case, why can't the metal mounts just be mass produced cheaply?

I don’t see how going back to the Wild West of the PC era is supposed to help these nontechnical users be safer. The App Store isn’t perfect but it’s far, far safer than that.

I have vivid memories of loads of relatives in the Windows XP era with browsers laden with toolbars that spy on everything they do and slow the computer to a crawl. Those users see something like the iPhone as a massive breath of fresh air. Nothing you install on the App Store can inject adware into the rest of the operating system like that.

No, latent space doesn't have to be made of percels, just like not every 2D array of 3-element vectors is an image made of pixels. Percels are tied to your sensors, components of what you perceive, in totality.

Of course there is an interesting paradox - each layer of the NN doesn't know whether it's connected to the sensors directly, or what kind of abstractions it works with in the latent space. So the boundary between the mind and the sensor is blurred and to some extent a subjective choice.

Yeah. Even a "firefighter" should be able to discuss the architecture(s) they inherited, and the associated strengths and pain points, and the tricky/interesting parts of the system. So I wouldn't view that as an impediment at all to this style of interview.

And I'm not interested in the sorts of specific details that go fuzzy over time. I'm interested in a big picture view of choices made and alternatives discarded. We should talk about some implementation details as well, but "I don't recall" is definitely an acceptable answer for some decently large percentage of those choices.

If you're talking about a Rails project you did ten years ago, I don't really care if you used Sidekiq instead of Resque or vice-versa. I mostly want to know if you know what sorts of jobs should be moved to background tasks and how you structure those jobs and what are the tradeoffs etc.

Also, if I (the interviewer) selected one of the candidate's more "boring" roles, I'd happily let them suggest we focus on one that is juicier and/or one where they were more involved in the design process.

This is probably one of those scenarios where if someone wants to fake it they're going to fake it (or at least it will be a never ending arms race, and I expect AI to keep close chase), while a basic security solution will suffice for 99% of use cases, including standard journalism. After all, skilled photoshop+computational tools can already do expert fakery in journalism. (Just look at the last Abroadinjapan video earlier today for a good callout of Photoshop editing to increase engagement).

What is the safety benefit of 48v? I am not an electrician, but I just finished diy/installing a 48v system, and when I was doing some research I read the opposite. 48v is *cheaper* since you don’t need as thick wires, but *more dangerous* since it has a higher chance of arc faults and the voltage is sufficiently high that it can cross the skin barrier and kill you.

Though all three are pretty safe as long as you buy the appropriate equipment, and take reasonable precautions when installing it.

Am I just a crazy cynic or are ZK proofs here just a buzzword.

Like, how is this any different than having each camera equipped with a vendor controlled key and then having it sign every photo?

If you can spoof the sensor enough to reuse the key, couldn't you spoof the sensor enough to fool a verifier into believing your false proof?

This is pretty cool!

I realize that you (the 13 year old) probably did not walk this path alone and I'm guessing you had a lot of help. Not sure how much help, but I don't mind giving you the benefit of the doubt today.

Great to see that you're being creative and (at least) participating in making things!

I know that it took a lot of work for my parents to encourage my passions and for me to actually pursue them in earnest. I could have easily gotten lost in being a consumer of media and programs. Instead, I make them and it is very fulfilling. I now have a lot to thank them for and I don't think I'd be here without all their hard work and hoisting me up in my youth. It sounds like you have parents that care that much and for that, you should be grateful and participate in your growth as they do.

Looking at the comments, it seem that many people hate ASN.1 and many people like ASN.1 (I am the latter). (I consider BER to be messy and overly complicated, but DER is much better.) (I wrote a implementation of DER (decoding and encoding), although not the schema format (which I have never needed).)

That description really resonates with me, it feels a lot like what I've been experiencing on and off for several months. I sometimes describe it like being able to see and examine an idea sitting in front of me on the table but having a hard time picking up and being able to manipulate it enough to write it out. Or like your fingers are working poorly like when it's very cold and you're not wearing gloves.

If you want accessing a particular page to cause a SIGSEGV so your custom fault handler gets invoked, you can just munmap it, converting that access from a "non-failing page fault" into one "deemed to be invalid". Then the mechanism I described would "allow[] concurrency of page faults, so the [userspace threading library] is able to perform concurrent reads against the underlying storage media". As long as you were aggressive enough about unmapping pages that none of your still-mapped pages got swapped out by the kernel. (Or you could use mlock(), maybe.)

I tried implementing your "hint_read" years ago in userspace in a search engine I wrote, by having a "readahead thread" read from pages before the main thread got to them. It made it slower, and I didn't know enough about the kernel to figure out why. I think I could probably make it work now, and Linux's mmap implementation has improved enormously since then, so maybe it would just work right away.

Hi there!

This is a comprehensive walkthrough of deploying Next.js apps to Dokploy, an open-source PaaS alternative to Vercel/Railway.

Key technical highlights: - Multi-stage Docker builds with standalone mode - GitHub Actions for CI/CD to reduce server load - Proper environment variable separation (build vs runtime) - Cloudflare integration for DNS and SSL

The guide assumes you're starting from scratch (buying a VPS) and takes you through to production deployment with automated updates.

I'm using this setup for several production sites now. Would love to hear if others have experience with Dokploy or similar self-hosted solutions!

> it is much harder to hold a corporation responsible

In some ways, yes. In most ways, no. In most cases, a massive fine aligns interests. Our problem is we've become weak kneed at levying massive fines on corporations.

Unlike a person, you don't have to house a corporation to punish it. Your fine simply wipes out the owners. If the enterprise is a going concern, it's born under new ownership. If it's not, its assets are redistributed.

> Jail is a great deterrent for natural persons

Jail works for executives who defraud. We just, again, don't do it. This AI could have been sold by a billionaire sole proprietor, I doubt that would suddenly make the rules more enforceable.

> (St)Roads where the kids have to cross a busy road to get to the other side where their house is.

That's pretty different from my experience.

Almost all the school bus stops around here are on small low-speed residential streets.

And while there are surely some stops on faster 2-lane roads...

A stroad or major road would mean 4+ lanes, which in my state means the school bus only stops traffic on one side. No kids will be crossing at those bus stops.

what I will say is: EV enshittification is the case because the technologies are so powerful. Never before have you been able to address so many parts of the car with sensors, cooling solutions, etc. The problem is the manufacturers and their ecosystems. GM is one particularly nasty car make that are making news for dropping their carplay/android auto support, but I remember our family eagerly buying their volt a few years after it came out, only later for it to have its battery packs remotely disabled so the dealership could take it in for a pittance. The US lets our carmakers get away with bloody murder because of their tie to the vision of an industrial America, but they've taken this liberty too far and like the electronics titans they ape, are trying to make their cars into a "gadget". This can be done right, just look at the 90s California EVs like the Ranger and Rav4. You can have a perma-car that is electric, the true limitation is if the infotainment system will let you.

The Software Freedom Conservancy thinks the GPLv2 guarantees the ability to modify existing GPLv2 software on a device, but does not guarantee the ability to still use the proprietary software running on top of that, and that the same applies with GPLv3. Reading the preamble of the GPLv2, I'm inclined to agree with them. Hasn't been tested in court yet though I think.

I don't think reputation gets you that far alone, we already live in a world where misinformation spreads like wildfire through follower counts and page ranks.

The problem is quality takes time, and therefore loses relevance.

We need a way to break people out of their own human nature and reward delayed gratification by teaching critical thinking skills and promoting thoughtfulness.

I sadly don't see an exciting technological solution here. If anything it's tweaks to the funding models that control the interests of businesses like Instagram, Reddit, etc.

> The reason for cost overruns is simply because NPPs are one-off products

But there's no fundamental reason they _have_ to be one-off products. They just historically have been for at least partly regulatorily motivated reasons: because each reactor's approval process starts afresh (or rather, did until quite-recent NRC reforms), there's little advantage in reuse, and because many compliance costs are both high and fixed, there's an incentive to build fewer huge reactors rather than more small ones, which makes factory construction difficult to achieve and economies of scale hard to realize.

BruceWok, thank you so much for this thoughtful feedback! These are exactly the kind of questions that push me to make the product better.

Let me address each of your points:

*1. AI consistency across long conversations:* Great question. Currently, each AI response includes the user's latest assessment scores in the prompt context, so it stays aligned with their 8 dimensions. However, you're right that maintaining coherence over weeks is challenging. I'm working on: - Session memory that tracks conversation themes - Periodic "consistency checks" where the AI reviews past advice - A feature to let users flag when AI advice feels off-track

*2. 12-week cycle engagement:* This is still early (just launched), but I'm tracking: - Weekly check-in completion rates - Drop-off points in the journey - What I've learned so far: Users engage most in weeks 1-2 (novelty) and weeks 10-12 (seeing results). The middle weeks need better nudges.

My hypothesis: Gamification + social accountability will help. Planning to add: - Milestone celebrations - Optional "accountability buddy" matching - Progress streaks

*3. Tighter feedback loop:* YES! This is critical. Currently building: - Behavior tracking (not just reflections): What actions did they actually take? - Outcome linking: Did their "resilience score" improve after following specific advice? - A/B testing different coaching approaches based on user response patterns

*4. Pricing & team/peer mode:* I love the idea of a team tier! It makes so much sense—growth happens faster in community. Added to roadmap: - Team dashboard (shared accountability) - Peer reflection circles (small groups) - Lower entry price point ($9.9/month "Growth Starter"?)

*5. Visualization & assessment evolution:* This is where I want to invest heavily. Plans: - Interactive growth timeline (not just static charts) - "Inflection point" detection (when did mindset shift?) - Comparative view (you vs. aggregated anonymous users)

You mentioned this is "one of the more thoughtful attempts" in AI coaching—that means a lot. I'm trying to avoid the shallow motivation content trap. Would love to stay in touch as I iterate. Can I reach out for a follow-up chat once I implement some of these improvements?

Thanks again for taking the time to try it and write such detailed thoughts!

Counting the two Independents as Democrats, who they caucus with:

Top 25 states: 2 Democrats - 52% 2 Republicans - 40% Split - 8%

Bottom 25 states: 2 Democrats - 36% 2 Republicans - 60% Split - 4%

Top quintile: 2 Democrats - 50% 2 Republicans - 40% Split - 10%

2nd quintile: 2 Democrats - 60% 2 Republicans - 30% Split - 10%

Middle quintile: 2 Democrats - 40% 2 Republicans - 60%

4th quintile: 2 Democrats - 30% 2 Republicans - 70%

Bottom quintile: 2 Democrats - 40% 2 Republicans - 50% Split - 10%

The very top and very bottom are a 55% to 45% split in either direction. It's not a heavy skew, a single party flip in the quintile from the majority to the minority would make it 50/50 even. Those quintiles cancel each other out when voting on party/caucus lines. It's actually the 2nd and 4th quintiles that have the biggest skews. Democrats take the 2nd quintile while Republicans take the 3rd and 4th.

> This is rather expensive for what looks like a home 3D printed toy with some cute software.

This attitude really rubs me the wrong way, especially on a site called Hacker News.

I think we absolutely should be supporting projects like this (if you think they're worth supporting), else all we're left with is giant corporation monoculture. Hardware startups are incredibly difficult, and by their nature new hardware products from small companies will always cost more than products produced by huge companies that have economies of scale and can afford billions of losses on new products.

So yes, I'm all for people taking risks with new hardware, and even if it doesn't have the most polished design, if it's doing something new and interesting I think it's kinda shitty to just dismiss it as looking like "a 3D printed toy with some cute software".

A huge benefit of the sea of nodes representation, at least how I envisioned it and we implemented in the early days of TurboFan, is that branch folding, load elimination, and all of the other forward dataflow analyses that do monotonic reductions can be combined into a single pass that operates on the IR in the optimal order and can iterate to a fix point efficiently.

Hollywood has gone through this before with streaming and it lost. When Netflix first started, Hollywood studios were willing to license their content. But as soon as they realized Netflix was threatening their future, they tried to resist by withholding their licenses. Netflix won by investing heavily in original productions and creating its own content.

Now it’s happening again with AI. A similar pattern is emerging. AI companies will start producing their own content and bypass Hollywood altogether. From what I hear, there are always screenplays available for purchase, so AI companies can simply buy what they need. These firms will learn new ways to create movies and ultimately come out ahead. Hollywood has no choice they better embrace AI now or wait until they are falling behind when they will have do it anyways.

It sucks but I think embracing AI is what all industries have to do. There is no choice.

You can Google it yourself. There are tons of studies showing a decline in technology literacy among younger generations (Z and alpha). Millennials were the peak.

This shows that younger kids aren’t using traditional PCs, at least not to the same degree. They just use phones and tablets. At best they may play games on their PC by installing via Steam. Very few of them are becoming proper technologists (able to install and use any software, script the computer, or write their own software).

The question is whether that Doritos carrying kid is still alive, instead of being shot at by the violent cops (who typically do nothing when an actual shooter is roaming a school on a killing spree; apropos the Uvalve school shooting, when hundreds of cops milled around the school in full body armor, refusing to engage the shooter on killing spree inside the school, and they even prevented the parents from going inside to rescue their kids) based on a false positive about a gun (and the cops must have figured that it's likely a false positive, because it is info from AI surveillance), only because he is white?
