The difference is that AI is not people "taking your stuff and building upon it", it's just people taking your stuff in direct competition with you.

To torture your metaphor a little, if information/"question answers" is food, then AI companies are farmers depleting their own soil. They can talk about "more food for everyone" all they want, but it's heading to collapse.

(Consider, especially, that many alternatives to AI were purposefully scuttled. People praise AI search ... primarily by lamenting the current state of Google Search. "Salting their carrot fields to force people to buy their potatos"?)

Setting aside any would-be "AGI" dreams, in the here-and-now AI is incapable of generating new information ex-nihilo. AI recipes need human recipes. If we want to avoid an Information Dust Bowl, we need to act now.

I love this website.

It doesn't have to be all or nothing. Some AI tools can be genuinely helpful. I ran a browser automation QA bot that I am building on this website and it found the following link is broken:

"Every Layout - loads of excellent layout primitives, and not a breakpoint in sight."

In this case, the AI is taking action on my local browser at my instance. I don't think we have a great category for this type of user-agent

I have (optery, not deleteme) and I think it's good to use at least once to clear out a buildup of your info out there. I couldn't justify paying for it monthly but if I was a semi-important person it might be worth it, or at least 1 or 2 months out of the year. Many brokers aren't responsive and it takes forever or never actually happens, and stuff definitely creeps back, but from what I can tell there is a heck of a lot less of me out there.

> Are all these post/mid-training tweaks important with abundant, verified, synthetic domain data?

No. Many are aimed at cleaning/aligning noisy, mixed-domain data. With abundant, high-quality domain data, you can skip most of the complexity and focus on direct SFT/RL on your corpus.

> Can a small team stick to scaling 2024-era best practices?

2024 was the year of SFT. I believe fitting reasoning traces to your final responses via RL is the technique-du-jour of 2025. Jumping from SFT to RL training might be biggest gain here if RL can be applied to your problem (e.g. math, coding etc).
Show HN: Trim – interactive, personalized summaries for students
by FabianAmherd | 2025-08-13 16:29:32+00:00
Trim is an application for university students that automatically generates summaries of entire lectures to help students excel at their finals.

The summaries are customizable and are presented in an interactive, visual hierarchy for maximum clarity.

I built Trim out of the frustration of a world filled with overly verbose content. Mainly aimed at students, but can easily be used across domains.

Go from information-sparse to information-dense in less than 2 minutes for entire books/lectures/courses.

Try it out at https://app.trim.run/

> 1. Layoffs and slowdown are global, not only in US.

Dunno about that. I've moved twice since 2022 (in Ireland), and the market is definitely less crazy but there's still (apparently) lots of work about. To be fair, I interview well and am pushing 15 years experience with a bunch of "prestigious" companies.

Definitely seemed like it much worse in the US. Then again, it was never as insane as the 2010's seemed for the US so maybe there was less over-hiring.

> 2. Expenses are still deductable, but over longer period. It makes no difference for big corporations.

The rate of change between full and 20% deduction definitely had a big impact on smaller companies hiring of software/data people. If you were a megacorp it mattered less but still not trivial.

No it in terms of flexibility of programming the SIMD is less flexible if you need any decision making. In SIMD you are also typically programming in Intrinsics not at a higher level like in CUDA.

For example I can do for (int tid = 0 ; tid<n; tid+= num_threads) { C[tid] = A[tid] * B[tid] + D[tid]; }

In SIMD yes I can stride the array 32 / (or in rvv at vl) at a time but generally speaking as new Archs come along I need to rewrite that loop for the wider Add and mpy instructions and increase width of lanes etc. But in CUDA or other GPU SIMT strategies I just need to bump the compiler and maybe change 1 num_threads variable and it will be vectorizing correctly.

Even things like RVV which I am actually pushing for my SIMD machine to move toward these problems exists because its really hard to write length agnostic code in SIMD intrinsics. That said there is a major benefit in terms of performance per watt. All that SIMT flexibility costs power that's why Nvidia GPUs can burn a hole through the floor while the majority of phones have a series of vector SIMD machines that are constantly computing Matrix and FFT operations without your pocket becoming only slightly warmer

> But you want to choose the content it summarizes.

Absolutely. The problem is that I think 95% of users will not do that unfortunately. I've helped many a dev with some code that was just complete nonsense that was seemingly written in confidence. Turns out it was a blind LLM copy-paste. Just as empty as the old Stack Overflow version. At least LLM code has gotten higher quality. We will absolutely end up with tons of "seems okay" copy-pasted code from LLMs and I'm not sure how well that turns out long term. Maybe fine (especially if LLMs can edit later).

I have 900gb in my account and on my 500mbps connection it took forever to download, not because of my speed but because of theirs and it just 'connection failed' at 80% many many many times and asking to relogin. It should be illegal. Not supporting just wget -c (you can use it with a lot of trouble/hacks and it's not reliable which defeats the point) is just clearly done to annoy you into not doing it.

The CLI is pretty simple, it accepts "key:filename" and performs these steps:

Open file and search backwards from end looking for marker bytes. If found, save the file date/time then extract the data and decrypt using AES. If the decrypted data passes a checksum test, place the data in a temporary file and load the file into a text editor. Wait for the test editor to exit. If the file has been changed, retrieve the data from disk, re-encrypt, place it back in it's hiding spot and restore the carrier file's original data/time. Lastly, overwrite the temporary file with random data before finally deleting and exit.

By the way, my little CLI can also perform TOTP generation. It will search for a section in the text delimited by "<--- 2FA Start" and "2FA End --->" for a list of "tag:=Base32 key string". To generate a TOTP code and place it into the clipboard, just give it "key:filename,tag".

> Does anyone know how exactly does Amazon get away with not providing data export for their eero product?

I checked eero.com. It seems info about the product other than “it’s a secure WiFi router that doesn’t require users to manage it” is in the videos, if it is on that site at all, but I couldn’t get the videos to play, so I may be wrong, but why would a WiFi router have personal data on the device?

It will have the username and password at your internet provider, but what else does it store?

No, a lot of bcachefs users are explicitly using it because of data loss, and they needed something more reliable; that's bcachefs's main reason for existing.

Besides that, if you want to make anything truly reliable, you have to prioritize reliability at every step in the process of building it. That means actively supporting it, getting feedback and making sure it's working well, and you can't do that without shipping bugfixes.

Having to ship a DKMS module just so users can get the latest bugfixes would be nutso - that's just not how things are done.

Yes, transit costs a total X. In the car regime everyone puts in a small amount towards public transit and roads and richer folk put high amounts towards cars, totalling X. In the public transit regime everyone puts in a medium amount towards roads and public transit, and a negligible amount of tradespeople and construction companies buy their work vehicles, totalling X.

You can choose the car regime if you want, the US does, but: 1- public transit is lower quality due to higher income brackets choosing cars. 2- everyone is screwed by the cars' negative externalities (noise and air pollution mainly). 3- lower income brackets are screwed by the traffic generated by the higher guys (50 minimum wage workers occupying the same lane space as 3 SUV-driving middle managers). Also you have to remember how much the mortality increases in higher car traffic areas, so that X figure isn't really true

I'm a bit lost here, and to be fair my memory from that long ago is a bit hazy... but I was a initial Pebble kickstarter and also got whatever the metal one was called.

They were totally fine products, I enjoyed using them. I am no longer using them, but such is the nature of consumer gadgetry.

I don't recall getting rogered at any point in that process?

They use a high efficiency low thrust hall effect engine - for those kinds of thrusters you might have to run it continuously, possibly continuously to ballance out the atmospheric drag at low altitude. For normal chemical thrusters you indeed use the for just a bit very occasionally (or else you run out of propellant very quickly).

Still I agree it is fixeable - they can tune the hall effect thruster on newer sats to not radiate in this band & avoid running the thrusters when in the field of view of that one radio telescope at the times it is operating.
Show HN: Index of fresh-capital VCs, accelerators, grants and –$4.5M freebies
by nischalb | 2025-08-13 16:33:39+00:00
I hacked this together last week; it’s still very experimental. The goal is simple: help founders prioritize outreach by surfacing investors who’ve recently raised funds (i.e., have capital to deploy). Right now we diff recent EDGAR/Form D filings and public announcements, normalize to a Postgres schema (fund → check size, stage, sector, geo, contacts), and do light entity resolution for aliases/shells. Expect gaps and false positives while we iterate.

Grants: today we’re only pulling federal sources (SBIR/STTR, Grants.gov). The roadmap is to add state, county, and municipal portals, plus agency- and foundation-specific programs—basically anything a startup can actually apply for.

Also included: accelerators/venture builders (terms, equity, timelines) and a “founder freebies” section (~$4.5M in credits/tools many teams miss).

We've kept it simple: no login wall, no upsell, no paid introductions. This is a working prototype we plan to keep improving.

> a public good is being commoditized

Just like the inclosure movement, right?

https://en.wikipedia.org/wiki/Inclosure_act

With privatization, the public is paid something. Whereas StarLink's use of LEO is a taking. They're denying others open access usage. Without any possibility or threat of consequences.

"Use" is such an inadequate term, but I couldn't think of another. Commandeering?

I was going to look up the same... I thought it was a little older than that... it's worth remembering that in 1981 there was no DNS yet, and even for dialup BBSes there were only a handful in the entire country as Hayes modems were new that year. Hell, for years a lot of business email services were dialup, grab packets, send packets and read/reply offline.

This is the same year the IBM PC was first released, and many people felt that would only see fairly limited sales. It wound up selling over 20x projections.

Nobody at the time really thought there would be a need for even more addresses. Not to mention the additional overhead of a wider network on the hardware at the time.

The issue is frontend can be a loaded question, especially if you are dealing with legacy stuff, different frameworks, etc. You also can't tell what the frontend code does by looking at that single line.

Now imagine as part of your analyzer, you have the following instructions for the llm:

--- For all files in `src/frontend/` treat them as frontend code. For all files in 'src/' excluding `src/frontend` treat as backend. Create a metadata called `scope` which can be 'frontend', 'backend' or 'mix' where mix means the code can be used for both front and backend like utilities.

Now for each file, create a `keywords` metadata that includes up to 10 unique keywords that describes the core functionality for the file. ---

So with this you can say

- `!ask find all frontend files`

- `!ask find all mix use files`

- `!ask find all frontend files that does [this]`

and so forth.

The whole point of analyzers is to make it easy for the LLM to map your natural language query to a deterministic search.

If the code base is straightforward and follows a well known framework, asking for frontend or backend wouldn't even need an entry as you can just include in the instructions that I use framework X and the LLM would know what to consider.

You can't make an arrest on the basis of refusal to verify identity, unless a specific law is in play, or the Police officer has proof you are lying.

If the police have probable cause to suspect you've committed an actual crime, then you have to ID yourself, you are entitled to know what crime you are suspected of. Yes, facial recognition does count, but it has to be a high confidence match >0.7, verified by a police officer personally, after the match is made, and verified again on arrest.

If you are suspected of Anti-Social Behaviour then you have to ID (Section 50 of the Police Reform Act)

If you are arrested, then you have to provide your name and address (Police and Criminal Evidence Act 2000).

If you are driving, you have to ID (Section 164 of the Road Traffic Act).

Providing false information or documents is a separate criminal offence.

Essentially, police can't just rock up, demand ID, and ask questions without a compelling reason.

The law is very clear, if you actually read it. It doesn't care what technology you use: cookies, localstorage, machine fingerprints, something else. It doesn't care. It cares about collecting, storing, tracking, and sharing user data.

You can use cookies, or local storage, or anything you like when its not being used to track the user (eg for settings), without asking for consent.

"The boolean operations are implemented using a graph-based approach. After the parsing the input, self-intersecting cubic beziers curves are simplified. Then the intersection points between all edges are calculated. These are then turned into a graph representation where every intersection becomes a new vertex. We then apply edge contractions to remove vertices with a degree of 2 to compute the graph minor. At this stage, identical edges are deduplicated. Because we are ultimately interested in the faces of the graph to decide if they should be included in the final output, we then compute the dual graph in which the faces become vertices and vertices become the new faces. That dual structure is then used to determine which faces (dual vertices) should be included in the final output."

This would be such a pain in the ass to implement with good precision and performance.

Tangent, there are these videos on YT of people walking through cities, the ones I like in particular are through Tokyo/Japan. I was thinking it would be cool to build a 3D map from that, it is possible but not my field. I think some companies have done it too. But there is a lot of data on that. Maybe free robot training (walking through a crowd like delivery).

I believe it's a combo of SLAM/photogrammery/VIO but you don't have an IMU so that part would have to be estimated from the video. Maybe the flickering of the lights with the frames probably too fast.

> If your receiver is so sensitive it's intolerant of stray EMI from a circuit board in outer space [...]

Well, that's what is required to receive a weak signal from beyond that circuit board, from outer space.

> there's no reasonable way to adapt to that

You'd be surprised what becomes reasonable and possible once a requirement is set.

> it's unreasonable to ask an entire planet to turn into a radio-quiet zone.

Noone is asking that.

It's reasonable to require radio interference of a device to stay within defined boundaries. This is the case in all other industries as well, why shouldn't it suddenly apply for a fleet of satellites which blast radio signals from outer space to earth?

This is one of the more concerning LLM use cases I would say is not a good idea. Most LLMs I’ve tested have the DSM-5 and other psych texts baked in. The problem I see with the idea is that they can’t proof their results. These inference engines can do sentiment analysis, which opens up a really good tooling opportunity for aiding a trained professional. What I see being problem though is that it’s too easy for a lay person to taint the context in ways the LLM can’t recover from. Also an LLM will have a really hard time calling someone out if they are blatantly lying to it.

What I really like about Caddy is their better syntax. I actually use nginx (via nginx proxy manager) and Traefik but recently I did one project with Caddy and found it very nice. I might get the time to change my selfhosted setup to use Caddy in the future but probably will go with something like pangolin [1] because it provides alternative to cloudflare tunnels too.

It's a neat idea. But if, as we're told, LLMs will get better and better, something like this, in theory, will be increasingly unnecessary.

I feel like most of the problems with AI using a library is how we mix code and implementation. C, C++ got it right (even if by accident) with separating specification from implementation.

Instead of lamenting the design trend of not maintaining this split, for my own code I wrote a utility to extract specifications from my existing code.

Your question doesn't really make sense.

You need to be more specific: are you talking about undergrad classes in person, online, or something like grad school? Why do you think that knowing graph algorithms is going to help you load voxel medical models (not graph structures, unless you're talking about image pyramids). GIS data viewers need a lot more klnowledge than just graph algorithms as well.

That said ... putting part of your soul into machine format so you can put it on on the big shared machine using your personal machine and expecting that only other really truly quintessentially proper personal machines receive it and those soulless other machines don't ... is strange.

...

If people want a walled garden (and yeah, sure, I sometimes want one too) then let's do that! Since it must allow authors to set certain conditions, and require users to pay into the maintenance costs (to understand that they are not the product) it should be called OpenFreeBook just to match the current post-truth vibe.

A "yellow flag" moment for me was OpenAI's revision of their Preparedness Framework in April 2025 to remove "risks related to persuasion" from the framework altogether.

https://cdn.openai.com/pdf/18a02b5d-6b67-4cec-ab64-68cdfbdde...

> Update the Tracked Categories of frontier capability accordingly, focusing on biological and chemical capability, cybersecurity, and AI self-improvement. Going forward we will handle risks related to persuasion outside the Preparedness Framework, including via our Model Spec and policy prohibitions on the use of our tools for political campaigning or lobbying, and our ongoing investigations of misuse of our products (including detecting and disrupting influence operations).

But, by their own definition, the purpose of this framework is:

> By “severe harm” in this document, we mean the death or grave injury of thousands of people or hundreds of billions of dollars of economic damage.

I would posit that presenting confident and wrong medical advice in a persuasive manner can cause the grave injury of thousands of people, and may have already done so. One could easily imagine an AI that is aligned to provide high-temperature responses to medical questions, if given the wrong type of incentive on a battery of those questions, or to highly weight marketing language for untested therapies... and to do so only when presented with a user that is somehow classified as more persuadable than a researcher's persona.

That this is being passed to normal safety teams and is being brushed off as in-scope for breakthrough-preparedness seems indicative of a larger lack of concern for this at OpenAI.

> The current preview implementation supports HTTP-01 challenges to verify the client’s domain ownership.

DNS-01 is probably the most impactful for users of nginx that isn't public facing (i.e., via Nginx Proxy Manager). I really want to see DNS-01 land! I've always felt that it's also one of the cleanest because it's just updating some records and doesn't need to be directly tethered to what you're hosting.
