> I have a hard time believing you are a recruiter for any FAANG company.

You just said you don't believe this person, now you are criticizing them for apparently being braggy about it (which they weren't).

They want to offer services for free and you are saying "No, no one wants that here.". Who are you to talk for others? If you don't like the free offer, just move on.

There was nothing bad about the original post.

Do your financial calculations take into account possible differences between Turkish and Portuguese practicalities? For example: is 1100 euro gross income or after taxes? What kind of unavoidable expenses you will have on top of rent: electricity, water, transportation, Internet/mobile, groceries, insurance and so on?

From my Nordic perspective, your budget will not leave much at all on the table at the end of the month. Groceries are probably more expensive here than in Portugal, but I still get a feeling that making the ends meet could be a real struggle. This kind of setup would be much more (financially) reasonable if you can live together with someone who is also working and then split the rent.

I suppose you took all of this into consideration already. Likewise, if you haven't already, it could be useful to search for some expat forums and ask people's opinions on anything that could be surprising in everyday life.

Either way you decide, iyi şanslar!
Show HN: Experimental Revocable Signatures Using Model-Based Encoding
by lyfeninja | 2026-03-03 13:15:44+00:00
Hi HN — I built an experimental demo that creates and verifies revocable digital signature artifacts using deep learning encoding models instead of traditional cryptographic keys.

In this system, a specific model instance encodes file metadata into a signature artifact. That same model instance is required to verify it. Signing authority is controlled through a short-lived “lease” (15 minutes), and can be revoked to intentionally invalidate verification.

This is not RSA/ECDSA, and I’m not making cryptographic claims or guarantees. I’m exploring whether the encoding method combined with short-lived authority can function as a signing primitive.

What you can do:
- Upload a non-sensitive file
- Generate a downloadable signature package
- Verify it later
- Revoke the signing authority and observe verification behavior change
- Session based. Files are processed in memory and not stored.

Core Properties:
- Signatures are encoded using a specific trained model instance
- Only the specific model instance can decode/verify the signature
- Authority is short-lived through a 15-minute lease
- Revocation is built into the design
- No long-lived private keys
- No blockchain or ledger

Challenge:

If you’re technically inclined, I’d genuinely love for you to try to break it. Specifically...

- Attempt to forge or reverse-engineer the signature artifact
- Modify files after signing and try to preserve verification
- Alter metadata in the signature package
- Replay artifacts across leases

If you can successfully forge or meaningfully reproduce a valid signature artifact without access to the model instance, I’d love to hear about it. This demo is intentionally inspectable and challengeable. I am not inviting attacks against the site or infrastructure — just scrutiny of the method and encoding assumptions.

Project info and write-up:
- https://lyfe.ninja/projects/#BlkBolt
- https://lyfe.ninja/news/#revocable-signature-demo

If there are obvious flaws, I’d rather learn that now than later. Thanks for taking a look.

I wrote the blog post a couple months back, and was considering the parts for the "computer" (Pi and adapter board alone) in that $20 estimate—the V3 version of the Pico Micro Mac is an additional $6.

But I'm assuming in that setup you have a VGA-capable monitor on a shelf somewhere; not everyone does, of course.

In the video I mention the all-in cost, accounting for the monitor, keyboard, mouse, power adapters, etc.

This isn't a practical setup by any means, but at least you wind up with a neat couple bits of hardware that could be repurposed once you get bored of it!

Is that the direction of causality or it's the other way around? Maybe people buy larger screens because they want to watch Netflix or TikTok on their phone more comfortably than on smaller screens. I do love small and light phones (an A40 right now) but I watch movies on a tablet. If I were often on the move or sharing home with many people, maybe I would use a larger phone.

On the contrary, the recent developments of America have made it very clear what the problem with "freedom to lie" and "freedom to smear" is. Especially when we're talking about adverts, which aren't exactly an important part of the discourse universe and are a potential vector for fraud.

(wait until the Americans understand what the rules for political TV broadcasts are in the UK, they will absolutely lose their minds. And the spending rules. And how little money is involved in UK elections.)

There's more serious concerns about UK libel law, and things like the proscription of Palestine Action, but generally I would say that if what you have to say is both true and important you can get your message across. Despite the newspapers and broadcasters.

I asked an AI agent to delete an unused folder. It pattern-matched too broadly and removed more than intended. I clicked "yes" too fast. Luckily I had a backup.

That was just files. Now imagine the same mismatch with `kubectl delete` or `terraform apply`.

So I built Evidra — an MCP server that evaluates infrastructure operations against OPA policies before execution. No LLM in the decision loop — just deterministic Rego rules.

What it catches: protected namespace deletions, mass resource removal, public S3 buckets, wildcard IAM, and similar high-impact mistakes.

What it's not: a full compliance engine or admission controller replacement. It's a lightweight pre-execution guardrail — works with AI agents, but also in CI pipelines against Terraform plans.

Every allow/deny decision is logged in a SHA-256 hash-chained evidence trail.

GitHub: https://github.com/vitas/evidra
Security model: https://github.com/vitas/evidra/blob/main/docs/SECURITY_MODE...

Would love feedback from anyone running AI agents against real infrastructure.
Show HN: MCP server that timestamps every web extraction for AI agents
by Prince-Gabriel | 2026-03-03 13:17:53+00:00
LLMs hallucinate recency. They'll tell you a project is active when it hasn't been touched in two years, or cite outdated docs as current. The problem isn't the content — it's that there's no timestamp on when it was retrieved.

FreshContext wraps every extraction in an envelope with retrieved_at, content_date, and freshness_confidence fields. The agent always knows when it's looking at data, not just what it says.

Ships with 7 tools: GitHub repo extraction, Hacker News sentiment, Google Scholar, YC startup scraper, GitHub repo search, npm/PyPI package trends, and extract_landscape — one call that queries all sources simultaneously and returns a unified competitive intelligence report.

Works locally (Playwright) and on Cloudflare Workers (Browser Rendering API). MIT license.

Would love feedback on the FreshContext envelope pattern specifically — is this a useful primitive for agent reliability?
Ask HN: How do agencies price projects when AI increases productivity and costs?
by hakonbogen | 2026-03-03 13:18:19+00:00
I’m curious how agencies and freelancers are pricing projects now that AI tools make us more productive but also introduce new costs. Many of us rely on LLMs, generative design, AI-assisted coding and other services that carry API fees or compute costs. If you can deliver work significantly faster with AI, do you still bill by the hour? Have you moved to fixed-price or value-based models? How do you factor in the overhead of AI tools without eating into your margins, and how do clients react? I’d especially like to hear from smaller agencies, designers and project managers who use AI heavily.

This is a big problem in the US and UK too. Lawyers are not technical at all and they need a robust system of governance, since currently they're (directly editing, not even diffing) documents with a chatbot which makes these mistakes inevitable.

There is a way to trigger a script when a budget is hit, but they don't make it easy. You set up a billing notification that triggers a script, which can disable resources (like APIs) automatically.

https://docs.cloud.google.com/billing/docs/how-to/control-us...

Google Cloud is easy to set up soft budget alerts via email though, something that I had to use third party service for with AWS.

I largely agree with you, but that's honestly the part I like. Just like your kids, there are folks here getting value out of something that wasn't accessible to them before. My most cherished artwork isn't the tasteful stuff, it's the crayon drawing my niece made for me on my wedding day. The low-stakes nature of this AI content feels similar; people are doing it for the sheer pleasure and aren't afraid of meeting anyone's bar. A lot of it is noise right now, but I suspect we'll see it develop into something really interesting if the pattern continues.

Yep, licensing fee and IP usage restrictions is a massive decision point on some silicon markets.

The other massive point: RISC-V integrates a lot of CPU "we know now" in a very elegant "sweet spot".

And it is not china only, the best implementations are US, and RISC-V is a US/berkley initiative re-centered in switzerland for "neutrality" reasons.

If good large RISC-V implementations do reach TMSC silicon process (5GHz), some markets won't even look at arm or x86 anymore.

And there is the ultimate "standard ISA" point: assembly written code then become very appropriate, hence strong de-coupling from all those, very few, sneaky backdoor injecting compilers.

On many of my personal projects, I don't bother anymore: I write RISC-V assembly which I run with a small x86_64 interpreter, that with a very simple pre-processor and assembler, aka SDK toolchain complexity close to 0 compared to the other abominations.

EDIT: important to note that abandoning the trenches and the frontline does not mean surrendering, and I never said they should surrender! I suggested evacuating the govt and continuing the resistance with other means - I don't believe the actual surrender would do any good.

You're right - the risks are, of course, very significant. And we've been through that here in Poland, historically, like 3 times already. We've had quite a few failed uprisings, and we've had anti-communist guerrillas here for a while after WW2 - they were quickly (it still took 3-5 years, though!) dismantled, and most of them were killed. So the risks are real, and it is a "desperate measure".

On the other hand, it worked quite a few times: Cuba, Vietnam, Afghanistan all proved that it's possible to win (or at least not lose) using guerrilla tactics. In case of Ukraine, I think the circumstances would favor the resistance: Russia's already not doing well economically; the "severe oppression" of the Ukrainians (which I agree would follow) would cement the support for the resistance, and it would cost Russia a lot; Russia had air superiority since day one, and it didn't really help them much (it would be much more of a threat had Russia have US-level intelligence capabilities - but they domonstrably don't).

Yes, as long as it's possible, the conventional war should continue. At some point, though, the costs (all kinds of them) of continuing to fight in the field become so high that it's better to stop and switch to other ways of defending.

I'm not saying that moment is now - and it's not for me to dictate when it happens - I'm just trying to say that there are other ways of dealing with the aggressor that may (in favorable circumstances) lead to lower casualties without forgoing the hope of eventually winning. Which I wish Ukraine with all my heart, BTW.
Show HN: Learnprints – a full learning OS I built solo on nights and weekends
by Jessyabc | 2026-03-03 13:21:16+00:00
I’m 25, work full-time at my family’s cabinetry company, and spent the last 9 months solo-building Learnprints (learnprints.ca) on nights and weekends with a ~$2,500 budget and a lot of searching and learning.

The frustration that started it: every learning tool I tried was optimized for engagement, not understanding. Anki is great but gives you no structure. Notion is a graveyard. AI chatbots answer questions but don’t build knowledge.

I wanted something that actually closed the loop.

What Learnprints does:
You give it any topic — quantum mechanics, corporate tax law, Renaissance art, anything — and it generates a Learnprint: a research-grade structural blueprint of that topic. Not a summary. A map of how the concepts relate, what the invariants are, what you need to understand before you can understand the next thing.

From there it’s a full loop:
∙ AI chatbot to clarify any concept inside the blueprint
∙ Spaced repetition that forces understanding, not memorization
∙ A cognitive mirror that builds a learning profile from how you actually practice
∙ A practice hub where you can upload assignments, get an AI tutor, draw on a canvas, and get passive feedback on your scratch work via vision AI

The whole thing is designed around one idea: depth compounds. A Learnprint you build today makes every future thing you learn in that domain faster.

The stack (full transparency):
∙ Frontend: Lovable, Cursor, Claude - Opus and Sonnet and a bit of Codex (AI-assisted React)
∙ Backend: Supabase (Postgres + Edge Functions)
∙ AI: GPT-5.2 for vision, GPT-4o-mini and GPT-5.2 for tutor and segmentation/structuring, LlamaParse for document extraction, Perplexity for the research layer
∙ Hosting: Vercel

What I’m looking for:
Launching at $15/month (CAD) with a goal of 10 paying users in 30 days. I have no marketing background — I’m a salesperson by day job and a builder by obsession. Roast the product, roast the pricing, tell me what’s missing. I can handle it. I want to improve and provide the educational tools I needed when I was in school to everybody.

> The same reason people generally don't regret having kids even though the commitment and overall change of your life are much greater than what you described for dogs.

They're definitely saying people don't regret having kids even though it's harder, meaning it's relevant/comparable to having a pet. But it's not, since your child isn't an animal you've chosen to have.

<%tp.file.title%> for aliases, it is necessary to always refer to the alias [[note|note alias]] notes in the text (if I refer without a pseudonym, then by accidentally or intentionally changing the name of the note, I can ruin the text in all places where it occurs

> At the same time, what is the standard by which it should be decided what is allowed and not allowed if not laws, which are passed by an elected Congress?

And that might be a compelling argument if the rule of law hadn’t been throw out the window. If secret courts didn’t exist. If “laws” couldn’t be twisted into pretzel or just outright ignored. If things, oh you know, like the name of the department he invokes throughout this article, could only be changed by the elected Congress instead of unilaterally changed by a mad king. Yeah, maybe then your article would hold water.

What an incredibly naive take on the current state of affairs.

I am a scientist who rarely collaborates (unlike programmers and unlike most scientists).

When I wrote a paper in collaboration some time ago, it felt very weird to have large parts of the paper that I had superficial knowledge of (incidentally, I had retyped everything my co-author did, but in my own notation) but no profound knowledge of how it was obtained, of the difficulties encountered. I guess this is how people who started vibe coding must feel.

Is there some philosophical/ethics work done on the question which fictional crimes, taboo breaks or unethical behavior are okay and which aren't? Iirc Japan takes the extreme position of legalizing all fictional wrongdoings, whereas the west is okay with fictional violence (e.g. murder mysteries), but not okay with some other things. Where to draw the line?

Microsoft did (does?) Installable File System plugfests. The anti-virus vendors always had a pretty full dance card because they go to great lengths to scan files, which is sometimes at odds with other drivers.

We had a hierarchical storage management driver, and getting files released to remote storage and keeping them released until the users actually wanted them back was helped greatly by actually being able to talk to the AV vendors and understand their criteria for when to scan.

At the time, a lot of AV filter drivers were legacy model drivers, which led to some serious shenanigans getting a second minifilter installed above the AV layer in the stack to distinguish between user and AV generated reads.

You control other people's fantasies?

I understand and agree with children, and bestiality being off-limits due to the non-consenting nature of any sexual interaction with them but a fantasy re-enacted by actors about incest/stepincest or even playing dead people? Why do you care? It's someone else's kink, not yours, you wouldn't like if the majority of people thought your vanilla sex kinks are off-limits (no more missionary for you, it's disgusting!).

Honestly I think it's a flaw in the algorithms of the various tube sites. There is no way in hell that having your step-sister stuck in a washing machine is the number one kink/fantasy on the planet.

Somehow the sites a providing incorrect feedback to the uploaders and creators, which skews HEAVILY towards adding stepmom/stepsister into the title and plot. Someone pointed out that it's a convenient "plot" for having two people in the same room, but apparently the adult industry never figured out that having the actors pretend to be a couple is an equally convenient plot.

There will be many more things like this and it’s an elephant in the room for the supposed mass replacement of people with AI.

Some human still has to be accountable. Someone has to get fired / go to jail when something screws up.

You can make humans more productive but for the foreseeable future you can’t take the human out of the loop to have an AI implementation that’s not a disaster/lawsuit waiting to happen. That, probably more than anything else, is why companies just aren’t seeing the much promised mass step change in productivity from AI and why so many companies are now saying they see zero ROI from AI efforts.

The lowest hanging fruit will be low value rote repetitive tasks like the whole India offshoring industry, which will be the first to vaporize if AI does start replacing humans. But until companies see success on the lowest of lowest hanging fruit on en-mass labor replacement with AI things higher up on the value chain will remain relatively safe.

PS: Nearly every mass layoff recently citing “AI productivity” hasn’t withstood scrutiny. They all seem to be just poorly performing companies slashing staff after overhiring, which management looking for any excuse other than just admitting that.
by txrx0000 | 2026-03-03 13:25:40+00:00
If the goal was to protect the children, there are much simpler solutions. But for whatever reason, companies and governments are avoiding the simple solutions like the plague.

Let me explain the simple solutions:

Don't let phone manufacturers lock the bootloader on phones. Let the device owner lock it themselves with a password if they want to. Someone will make a kid-friendly OS if there is market demand and tech-savvy parents can install that and lock the bootloader.

What about the non-tech-savvy parents?

Don't restrict people from sideloading apps. Let the user set a password-based app installation lock if they want to. It should be a toggle in the phone's settings. Someone will make kid-friendly apps if there is demand. This lets average parents control what apps get installed or uninstalled on their kid's phone.

But what about apps or online services that adults also use?

Apps and online services can add a password-protected toggle in their user account settings that enables child mode. Let the user set the password and toggle it themselves. Parents can take their child's phone and toggle this.

----

Notice how easy these things are to implement? All of these features could be implemented in less than a week. But instead of doing this, they want to implement much more complicated schemes where the gov and corps control all the toggles, and you control none. Why is it like that? Surely there are no ulterior motives, right?

This is why LLMs won't replace humans wholesale in any profession: you can't hold a machine accountable. Most of the chatbot experiences I have with various support channels always end up with human intervention anyway when it involves money.

Maybe true general intelligence would solve these issues, but LLMs aren't meeting that threshold anytime soon, imo. Stochastic parrots won't rule the world.
