Afaict the "desktop" target is meaningless these days. Desktops aren't really a thing anymore in the general sense are they? Only folks I know still hanging on to desktop hardware are gamers and even those I see going by the wayside with external video cards becoming more reliable.

"Daily driver" is probably a better term, but everyone's daily usage patterns will vary. I could do my day job with a VT100 emulator on a phone for example.

> This could be achieved using a USB dongle.

What stops one from selling access to that USB dongle over the internet, anonymously doing thousands of verifications per second, cardsharing[1] style?

With Google Play Integrity Protection, each such verification needs a human physically clicking buttons on the device, which makes things much harder.

I don't think the cheap light sensor would have a fast enough polling rate for that. And if you increase the polling rate I will just put a phosphorescent sticker that absorbs and reflects the light coming out of the led with a good enough afterglow that the photoresistor will still pick up as some value and still allow for recording.

Also what is the implication here? If you cover the hole accidentally for one microsecond do you invalidate the whole recording? Does it need to be covered for more than one second, two seconds, ten?

All of that for what? So that in 2 years we can have chinese off-brand clones for 50 dollars that offer no security mechanisms anyways?

We all need to understand this is the new normal, being able to be recorded anywhere anytime. Just like you can get punched in the street anywhere anytime. We only act on things that can be proven to have caused you prejudice in court.

As a dev, I think the core issue isn’t whether one indicator LED can be bypassed — motivated people can bypass almost any client-side control. The trust boundary is policy + defaults. If enabling “AI features” implicitly authorizes broad retention/review, users won’t understand the tradeoff until after the fact.

A better pattern would be tiered modes with explicit UX: local-only capture, cloud processing without retention, and opt-in retention/training with visible status. If the product can’t technically support that separation today, that limitation should be stated plainly in setup, not buried in policy docs.

The factories are the weak link to all munitions.

The Iran-Iraq war was decades ago, every weapon system has changed.

Iran has anti-ship missiles they can fire with impunity at tankers - and - as I said Shaheds.

Shaheds are not yet used against moving targets, but it's plausible they are ready for that.

If they are, then they can close the straits.

The reason they would not likely close the straits is that China is the primary recipient of that Oil, and it's a bit of a client state. China paradoxically provides parts for those drones. And they are the 'last remaining frenemy ally of Iran'.

So the nuclear option is very nuclear.

Yeah, Google stopped even trying to usefully index most of the web around ‘08 or ‘09 or so. Was super obvious when it happened and it’s been that way ever since. Your GitHub is up there because it’s a blessed website, your personal site isn’t and will struggle mightily to rank even when you search exact, unusual phrases on it, if it’s like most of the rest of the Web on Google these days.

Get more traffic (make sure google analytics sees it, IDK but that probably matters because monopoly) and it might help.

Most of the other indices aren’t much better. Turns out fighting spam is expensive, easier to just do a combo of boosting really big sites and blessed spammers that use your ad network.

We're building an open-source tool that makes your screen activity searchable via AI.

Processing hundreds of screenshots/hour forced us to optimize for token costs.

The surprise: send video, not images

- Single screenshot (1698×894): 1,812 tokens

- Same frame in video: 258 tokens (Gemini 2.5) or ~70 tokens (Gemini 3)

- Full 8-hour workday: ~$1-3

Video gives you timestamps for free and compresses well since consecutive frames are nearly identical. We keep costs down by having the LLM write short summaries while running OCR locally for text extraction.

It's worse than that. There's a SECOND imitator that I actually stumbled on today while looking something up about nanoclaw - nanoclawS [dot] io - and that one's harvesting email addresses.

The obvious risk here is a bait and switch, where one of these sites switches their link to the Github repo to point to a malicious imitator repo instead.

One approach would be to go after the sites themselves, not their Google ranking. See if their hosts are willing to take them down. Is there anything you can assert copyright over to hang a DCMA request on? That's hard for an Open Source project, I guess. And the fake sites aren't (yet) doing any actual scamming.

Good luck, though!

> This is a great insight. For software engineers coding is the way to fully grasp the business context.

> By programming, they learn how the system fits together, where the limits are, and what is possible. From there they can discover new possibilities, but also assess whether new ideas are feasible.

Maybe I have a different understanding of "business context", but I would argue the opposite. AI tools allow me to spend much more time on the business impact of features, think of edge cases, talk with stakeholders, talk with the project/product owners. Often there are features that stakeholders dismiss that seemed complex and difficult in the past, but are much easier now with faster coding.

Code was almost never the limiting factor before. It's the business that is the limit.

I never had full 90 degrees up on one wing but I had 40-60 degrees which was enough for me to know I didn't like it.

Winds aloft were 30-40kts and there is a pass in the mountains east of Asheville NC at Chimney Rock we would fly over regularly. On that day I caught what I assume was mountain rotor and it was like being on a mechanical bull.

Any longer or harder than someone using a car, knowing full well the depravity for war caused by a lust for oil, and the chance to get into a car crash every time they get behind the wheel? Or every smartphone user for the use of slavery to procure cobalt the device is dependent on to function?

There's also a chance it could lead to something better. If everyone should rely on their family for help, then if you have the skills to take advantage of the AI boom, then you have a duty to make as much money as possible in order to better be able to provide for said family as times change.
Show HN: FixYou – AI tool that tells you which cancer screenings you need
by forrestzhong | 2026-03-03 14:02:45+00:00
The USPSTF and ACS publish thorough cancer screening guidelines, but they're dense and scattered across dozens of pages. What you actually need depends on your age, sex, family history, smoking status, and other factors. Most people, including me until recently, simply don't know what they should be getting checked for.

I built FixYou after losing my grandfather to colon cancer that was caught too late. After his diagnosis, my parents went for colonoscopies and found polyps, early and treatable. We didn't lack access to healthcare. We lacked clarity.

FixYou is a free tool that:
1. Walks you through a short AI conversation about your health profile
2. Cross-references your answers against current USPSTF and ACS screening guidelines
3. Gives you a "Shield Score" (0 to 100) and a prioritized list of screenings to schedule

The goal isn't to replace your doctor. It's to prepare you for the conversation, and to be the nudge that gets you to actually book that colonoscopy or mammogram you've been putting off.

March is Colorectal Cancer Awareness Month, which felt like the right time to share this.

Would love feedback on the scoring logic, the screening recommendations, or anything else. Happy to answer questions about the approach.

Show HN: Corepoints – Screen Candidates for AI Proficiency at Scale (Demo Run)
by abhiparuchuri | 2026-03-03 14:03:18+00:00
It's extremely difficult for founders, recruiters and hiring managers to screen their candidates for AI proficiency at scale.

That's why we built Corepoints. You can create and send OAs where AI usage (with AI chat) is a core metric.

You have full control of the testing environment: hallucinations, data leakages, LLM behavior + Grade candidates on aspects such as their answer accuracy (of course), prompting quality, reasoning quality, hallucination susceptibility, token usage, and more.

We're currently doing a demo/beta run for about the next month or so that we can iterate off feedback, no payment/commitment required that we can iterate off feedback.

You can request an account here: https://app.corepoints.ai/request-access

All comments, suggestions, and feedback are welcome and much appreciated. You can also reach us at hello@corepoints.ai !!

Thanks everyone.

Hi HN,

I built PrecisionAudit because I got tired of the default "turd polishing" reflex of Large Language Models.

Whenever you ask ChatGPT to improve landing page copy or a cold email, its default behavior is to inject words like "revolutionize", "seamlessly", or worse—invent fake round numbers like "boosts ROI by 300%". It generates "fake confidence."

PrecisionAudit is a strict, dual-agent system designed to do the exact opposite: strip away the BS, penalize unverified claims, and force B2B copy to be mechanism-driven.

How it works under the hood:

Agent 1 (The Brutal Evaluator): It scores your text based on strict mode-aware rubrics (SaaS Landing Page, Cold Email, Pitch Deck, etc.). We implemented a "Hard Ceiling" rule: if your input text lacks verifiable real-world metrics or case studies, your "Specificity" score is hard-capped at 7/10. It actively flags generic percentages as unsupported_claims.

Agent 2 (The Rewriter): It has strict system prompts forbidding it from strengthening fake claims. If it sees "increases speed by 50%" without proof, it neutralizes it into a defensible outcome like "removes manual data entry friction". It also strips out all Markdown formatting to give you raw, copy-ready text.

Mode-Awareness: It knows that extreme brevity and a soft CTA in a Cold Email is a feature (10/10), but the same brevity in a Pitch Deck is a flaw.

Tech Stack & Anti-Abuse:
Built with Next.js, Firebase Admin SDK, and OpenAI (gpt-4o-mini with low temp and fixed seeds for determinism). We handle credit deductions using db.runTransaction to prevent race conditions from concurrent requests. There's also a hidden "sandwich watermark" injected into the rewritten text to prevent users from accidentally burning credits by re-auditing already optimized copy.

You get 5 free credits via Google Auth to play around with it.

I’d love for you to throw your worst, most hyped-up, fluff-filled marketing copy at it. See if you can bypass the guardrails or if the system successfully neutralizes the BS.

Brutal feedback is highly appreciated!

Yep. Aiphor's BlueFox NX1 with 4 inch screen is roughly the same size as original iPhone, but has a larger screen (iPhone had bigger bezels and the home button underneath). To me it feels a bit too small for things like typing/texting for example.

Unihertz Jelly Star has 3 inch screen, that's way too small for me.

But they exist and so do people who buy them.

I spent the past year asking why every MCP security tool is a scanner that runs before deployment — when the attacks that actually work (rug pulls, runtime tool poisoning, cross-server escalation) happen after. Scanners catch known patterns in config files. They can't catch a tool server that changes its schema after you approved it.
So I built a runtime enforcement layer instead. VellaVeto is a proxy that sits between your MCP client and tool servers, evaluating every call against policy before it executes. If policy evaluation fails for any reason — missing context, internal error, no matching rule — the call is denied. Fail-closed, not fail-open.
Try it:
cargo install vellaveto-proxy && vellaveto-proxy --protect shield -- ./your-mcp-server
That single flag blocks credential grabs (.aws/.ssh/.env), exfiltration domains, injection patterns, and DLP leaks with no config files. Two stricter modes (fortress, vault) go up to default-deny with human approval for writes.
The core is Rust (~92%), <5ms P99 evaluation. Policy engine properties are formally verified in TLA+ (fail-closed under network partition, no policy bypass on concurrent evaluation) and Kani (no panics in library code). These cover the engine's core invariants — not a claim about the full system.
I also built MCPSEC, a vendor-neutral benchmark for MCP gateways — 10 properties, 64 attack tests, 12 attack classes. Apache-2.0 licensed, runnable against any gateway: https://github.com/vellaveto/vellaveto/tree/main/mcpsec
To be clear about what this doesn't solve: MCP's fundamental problem is that control and data share the same channel. No proxy fully fixes that. VellaVeto is a defense-in-depth layer — it catches a meaningful class of attacks at the tool-call boundary, but it's not a silver bullet against prompt injection.
Licensing: core is MPL-2.0 (open source). Enterprise crates are source-available under BUSL-1.1, free for deployments under 3 nodes / 25 endpoints, and each version converts to MPL-2.0 after 3 years.
Would love feedback on the approach, the benchmark methodology, or the threat model.

I like the thought behind the piece, but what I think the criticisms are reacting to is the profusion of short, bursty sentences (just like the ones in the parent post), which can be great when used sparingly, but start to feel repetitive and have a "LinkedIn"-ish vibe, at least to me. For example the very end:

Most of you won't be able to answer that. And you already know it.

That's the conversation this industry needs to have. Not tomorrow. Now.

I hope you don't take this the wrong way and do continue writing - I enjoyed this piece, just wanted to give some constructive feedback

> I don't understand why are you downvoted. Are people in this thread really pulling out a laptop and trying to get it connected (or pay for one with a cellular modem) every time they need to respond two words to an email, call a uber or look up where is the nearest coffee shop that is open at an odd hour?

Because some of us read the original comment and thought maybe the discussion should be responsive to it:

> If the task can’t be done in a few taps I feel I’m better off opening a laptop anyways.

Talking about Uber, email and directions in Maps are literally "task[s] that can be done in a few taps". Perhaps being less "weirdly" defensive and taking the time to think about the discussion you're about to jump into would be helpful?

We had a similar experience — looks like someone used AI to clone our site's design and structure at linuxtoaster.com. The real issue Gavriel is highlighting goes beyond SEO. The cost of creating a convincing copycat site just went to zero. Anyone can feed a successful page to an LLM and get a polished clone in minutes. And for open source projects it's even worse — they can clone your website AND clone your code, have an AI rebrand it, and ship a convincing-looking alternative overnight.

I'm not sure these people like Windows as much as they like what it does for them, but they are willing to put in significant effort to remove the normal Windows roadblocks and annoyances, and thus are willing to hack and chop it to bits to get them closer to their end goals more quickly.

They're not like a car enthusiast who loves their MX5 out of its sheer beauty and feel, but rather they love their SUV because of it's big boot and because it gets them where they need to be, and thus are perfectly happy to tear out the old radio and uncomfortable seats.

The only difference is that car enthusiasts have many more options to choose from, while in OSes, if you're stuck with Windows, you're usually really stuck with it. Linux is certainly an option, but not one that is universally practical to apply.

I think this is an even clearer case than usual. With software engineers and office work you don’t have legal limitations on who can perform the work, but they exist for lawyers and doctors for example.

So if this is a tool, the fault lies fully in the user, and if this is treated as “another persons work” then the user knowingly passed the work onto someone not authorized to do it. Both end up in the user being guilty.
