Show HN: Rollin – Wheelchair accessibility scores for 56K+ locations (free API)
by thattechiedude | 2026-02-16 18:07:30+00:00
Solo dev, Hudson Valley NY. I built ROLLIN because Google Maps
gives wheelchair users a yes/no checkbox and calls it accessibility data.

ROLLIN scores locations 0-100 across 6 features: wheelchair entry,
accessible restroom, level entry, parking, wide aisles, elevator.
Data pipeline pulls from OpenStreetMap, cross-references Google Places,
and layers in community verification with a trust-weighted scoring system.

Stack: Vanilla JS (no frameworks), Netlify serverless, Supabase/Postgres,
Leaflet maps. ~56K locations across NY, CA, FL, MA, NJ, PA.

Free to use, free API tier for developers. Paid tiers for
higher volume and commercial use.

Ill be happy to answer any questions. :)

I've shucked WD MyBook drives, just a plain SATA inside. I guess that it's cheaper to have a stock drive and a cheap SATA-USB adaptor in a shell than do custom electronics. I've not heard of any that are otherwise, but I've only done a few. I suppose it's possible that they could solder them in or have custom electronics but I would have thought that rare. It's frequently discussed on Reddit too, so there's plenty of folk doing this.
Show HN: Hardware-signed photos with C2PA on mobile
by frankLopez | 2026-02-16 18:07:42+00:00
Heey

With all the AI stuff that's happening now, checking the provenance of photos will be a reality sooner rather than later. C2PA is the standard for this. Leica and Sony already ship it in some cameras, but I couldn't find anything for mobile that didn't require a whole SDK. So I built it.

It's a React Native package. You take a photo with whatever camera lib you want, pass the path to signPhoto(), and it hashes the image, signs it with the device's Secure Enclave (iOS) or StrongBox/TEE (Android), and embeds a full C2PA manifest into the JPEG. The file that gets saved is already signed.

Where I think this actually matters:
- insurance apps (prove damage photos are real)
- marketplace listings (verified photos for cars/real estate)
- field inspections, KYC selfies. Anywhere someone has an incentive to submit fake photos.

https://github.com/RoloBits/attestation-photo-mobile

Would love feedback, especially from anyone who's worked with C2PA or hardware attestation on mobile.

Wes Bos has a pretty cool demo of this: https://www.youtube.com/watch?v=sOPhVSeimtI

I really like the way you can expose your schema through adding fields to a web form, that feels like a really nice extension and a great way to piggyback on your existing logic.

To me this seems much more promising than either needing an MCP server or the MCP Apps proposal.

The question isn't something you'd ask another human in all seriousness, but it is a test of LLM abilities. If you asked the question to another human they would look at you sideways for asking such a dumb question, but they could immediately give you the correct answer without hesitation. There is no ambiguity when asking another human.

This question goes in with the "strawberry" question which LLMs will still get wrong occasionally.

Courtsdesk are rather misrepresenting this situation.

Quoting from an urgent question in the House of Lords a few days ago:

> HMCTS was working to expand and improve the service by creating a new data licence agreement with Courtsdesk and others to expand access to justice. It was in the course of making that arrangement with Courtsdesk that data protection issues came to light. What has arisen is that this private company has been sharing private, personal and legally sensitive information with a third-party AI company, including potentially the addresses and dates of birth of defendants and victims. That is a direct breach of our agreement with Courtsdesk, which the Conservatives negotiated.

Or in the case of, down the road, repeating an offense. The judge sees you had an issue in the past, was good for a while, then repeated, suggesting an event or something has happened or that the individual has lost their motivation to stay reformed. Sentencing to time for the crime but then also being able to assist the individual in finding help to get them back on track. We have the systems in place to do this, we just don’t.

Also, when applying for a loan, being a sex offender shouldn’t matter. When applying for a mortgage across the street from an elementary school, it should.

The only way to have a system like that is to keep records, permanently, but decision making is limited.

Have you thought about building a RISC-V “fantasy computer” core for the MiSTer FPGA platform?
https://github.com/MiSTer-devel/Wiki_MiSTer/wiki

From a software-complexity standpoint, something like 64 MiB of RAM possibly even 32 MiB for a single-tasking system seems sufficient.

Projects such as PC/GEOS show that a full GUI OS written largely in assembly can live comfortably within just a few MiB:
https://github.com/bluewaysw/pcgeos

At this point, re-targeting the stack to RISC-V is mostly an engineering effort rather than a research problem - small AI coding assistants could likely handle much of the porting work over a few months.

> The prompt cache caches KV Cache states

Yes. The cache that caches KV cache states is called the KV cache. "Prompt cache" is just index from string prefixes into KV cache. It's tiny and has no computational impact. The parent was correct to question you.

The cost of using it comes from the blend of the fact that you need more compute to calculate later tokens and the fact that you have to keep KV cache entries between requests of the same user somewhere while the system processes requests of other users.

Excellent, thanks.

I don't quite know what this is - it's a new concept, to me, at least - but it's pressing some good buttons in my head.

I just realised, after testing that I'd inadvertently gine a bit too close to home, literally, when adding a note :)

Bookmarked, keeping an eye on you develop this!

2006, the year that Tool's 10,000 Days had been released, which I was enjoying and, being a bit of an Edge Lord, I'd named my device after a lyric from Vicarious - which, IIRC fit perfectly into the name space and made me very happy:

Yes, but if they weren't overproduced and then either run into the ground or left waiting for demand that would never come, then wouldn't those memory chips and precious metals all still be more available than otherwise...?

I mean, sure, yes, we can try to recycle waste products—but it's still less wasteful not to produce them unnecessarily in the first place.

Congrats on shipping, especially on paternity leave. The blind ranking + synthesis approach is solid for general Q&A.

One thing we've been exploring: the synthesis step tends to flatten interesting disagreements between models. When GPT and Claude genuinely disagree about something, that disagreement is often the most valuable signal -- it usually points to genuine uncertainty or tradeoffs worth examining.

We've been building this at wisepanel.ai -- using a patent-pending method to construct dialectical roles that surround the cognitive space of a question to unearth the most contrast possible, and hence maximize innovation, which we believe comes at the intersection of disparate knowledge domains. Rather than having all models answer the same prompt, the structured interaction between these roles surfaces things that consensus-based synthesis tends to smooth over.

Curious whether you've seen cases where the blind ranking discards a minority opinion that turned out to be the most useful response?
by quroi | 2026-02-16 18:11:03+00:00
The side-by-side comparison + fusion approach is useful, but the interesting question is what happens between comparison and synthesis.

When you fuse 5 responses, the synthesizer model has to resolve disagreements. In practice it tends to pick the majority view and soften the edges. That works for factual queries, but for decisions with genuine tradeoffs (architecture choices, build vs buy, strategic bets), the minority opinion is often where the real insight lives.

We've been exploring this at wisepanel.ai -- using a patent-pending method to construct dialectical roles that surround the cognitive space of a question to unearth the most contrast possible, and hence maximize innovation, which we believe comes at the intersection of disparate knowledge domains. Rather than asking all models the same prompt and fusing after, the structured interaction between these roles makes disagreements intentional rather than accidental.

The cost comparison to Perplexity's $200/month Model Council is fair, but the deeper issue is that both approaches use the same consensus architecture. The value gap isn't in price -- it's in whether you preserve or flatten the disagreements between models.

Aligned pulls from your chosen sources (RSS, Substacks, blogs, or just topics), and every morning at 5am your time it generates a 5-minute audio briefing. But it's not just summarization — during onboarding you set a goal (what you're actually trying to achieve) and per-topic expertise levels (exploring, foundations, or deep).

A founder exploring AI gets a completely different episode than a researcher deep in the field. Same sources, different output.

Stack: Node/Express, Supabase (Postgres + CDN storage), Claude for ranking/scripting, OpenAI TTS for audio, Railway. Hourly cron checks which users have hit 5am in their timezone.

First version took less than a day to build. This is about a week in.

I'd love honest feedback. is a daily 5-minute audio briefing on your topics actually useful to other people, or am I the only one who wants to be updated this frequently?

> Microsoft’s AI CEO is saying AI is going to take everybody’s job. And Sam Altman is saying that AI will wipe out entire categories of jobs. ANd Matt Shumer is saying that AI is currently like Covid in January 2020—as in, “kind of under the radar, but about to kill millions of people”.

> I legitimately feel like I am going insane when I hear AI technologists talk about the technology. They’re supposed to market it. But they’re instead saying that it is going to leave me a poor, jobless wretch, a member of the “permanent underclass,” as the meme on Twitter goes.

They are marketing it. The target customer isn't the user paying $20 for ChatGPT Pro, though; the customers are investors and CEOs, and their marketing is "AI is so powerful and destructive that if you don't invest in AI, you will be left behind." FOMO at its finest.
Ask HN: Feedback Loop with Coding Agents?
by hcwilk | 2026-02-16 18:11:54+00:00
I've been using Claude Code ever since it came out, and I've seen good success with it. However, Matt Shumer's recent article [1] included a piece I'm curious about:

When describing his workflow now, he says "Then, and this is the part that would have been unthinkable a year ago, it opens the app itself. It clicks through the buttons. It tests the features. It uses the app the way a person would."

Unless I missed a major development, do these coding agents have the ability to use feedback loops like this? If so, how have you all built this functionality into your workflow?

Any guidance / advice / documentation I can read would be super helpful!

As I automate more and more of my agentic coding process, I've come to realize that a swipe-based UX is very likely to dominate corporate decision making in the years to come.

The posted link is a research report on the topic - in full disclosure generated by a custom research agent I've been working on.

I'm sure that others are working on other novel UXs for fast decision making to coordinate their agents. I'd love to hear any insights you've gained so far.

> being IoT or BT enabled

Please don’t conflate these two. I have lots of BLE wearables and other sensors. They only send data to my own computer which I control, unlike IoT devices which by definition send to a third party on the Internet. To me it is far more important to protect against strangers on the Internet versus someone wardriving the neighborhood.

On a related note, did you know that EU has a Radio Equipment Directive (RED 2014/53/EU) that came into effect in 2025. It all but guarantees that such Bluetooth communication will be encrypted.

Everyone has somehow forgotten Hugh Hefner and Playboy being a cultural and business masthead in a media empire built on the same principles of fetish and control as Epstein's little Deutchnyland. Where did Epstein learn his ways?

The term "survivor" is generously espoused when remarking on "victims" of Epstein's network in the midst of 500 years of an enormous overwhelming elite class war, which at this moment in history is manifesting, again, via enormous funding for centralized domestic policy of jackbooting and human trafficking capping a foreign policy of literally blowing people up to preserve narrow ideological and monied interests.

By every measure, Epstein was a modern, well-loved and accepted central figure in the business network that manifests in policy of wrecking lives and we all take pride in this network.

The Epstein outrage might be understood as justice if it were in any way related to these larger abuse networks, but it cannot be understood this way. It's instead sequestered to an Epstein-island of hysteria that's being carefully managed by the same policy makers and media complex that runs the war networks.

Even when we denounce Epstein we're still taking pride in this system.

The needed awareness of this could not be closer to home than here at YC, but like Chomsky, everyone thinks s/he is above and beyond the horror.

I know Turbo Pascal produces really bad code (even in later versions), but it's not on the same level as a non-optimized Forth. Function prologue on x86 doesn't have much overhead either.

It's somewhat closer for 8-bit processors, the most popular ones had either no convenient addressing mode for stack frames at all, or an extremely slow one, like IX/IY on the Z80. For even more primitive CPUs, you might already need a virtual machine to make it "general-purpose programmable" at all -- for example if there is only one memory address register, and no way to save its contents without clobbering another one. I think that some of Chuck Moore's earliest Forth implementations were for architectures like that.

Also memory constraints could have been more important than efficiency of course. I'm not saying Forth is worthless, but it's not competing with any compiled language in terms of speed, and IMHO it also does away with too many "niceties" like local variables or actually readable syntax. Your mileage may vary :)

> Being able to easily interact with banks, without waiting in a line that’s too long for the dum-dum you get at the end to be a real consolation, made people use banks more.

Actually, in my city, not the ATMs, but the apps which made it possible to do almost everything on the phone significantly reduced the number of banks in the last few years. I have to go very rarely to the bank, but, when I have to do, I see that another close one has closed and I have to go somewhere even farther.

Its never been easier to release a saas app. But getting to production is a longer road. Having built 2-3 SaaS apps recently to small profits, I wanted to bundle everything into a re-usable product. It is also an attempt to reduce token cost

Before LLm I used to use yeoman generators like `JHipster` it saved so much time from decision making and writing boilerplate.
Most existing generators are not LLm friendly unless they make an effort to add some guidance or the LLm was trained on the codebase.
There is also the problem of selecting the right tools which works for 1 developer/ solo founder and all the way to teams.

I chose the tools I use for my production SaaS apps now, they work well and cost nothing to start. all Self-serve, no sales people, no approval gating

This is just a first release but I imagine we can reduce token usage further. At the moment this base generator with Codex can reduce your usage by 80-90% and get you closer to launch.

I have included comments from some solo founders I follow i have met in person , so while TS/Nextjs would not be my choice (i come from Java/Python) it has made sense from a solo founder perspective. lessons learned the hard way. I dismissed the advice initially but some founders were right, Just Release It (possibly trademarked).

I have tried to let Codex and agents harness as much possible. If needed I will manually patch things.

How to use:
The generator should give you a starting point of an app. Some configuration and then you can let Codex take over.

npm https://www.npmjs.com/package/@justlab/create-saas-stack

I have published to npm after a very long time please excuse any issues for now.

pnpm is used so i still need to update readme for that

quickstart
`npm create u/justlab/saas-stack@latest my-app -- --yes` or drop the auto `--yes` and select options

what you get out of the box.
Auth, payments, a structured project, local docker dev, Docker deployment (should be straightforward if you deploy to vercel, but i left it open), emails , authorization, basic DB structure for Supabase.

Right, except there are some cases where that information should be disclosed prior to their death. Sensitive positions, dealing with child care, etc. but those are specific circumstances that can go through a specific channel. Like we did with background checks.

But that's a tautology. The Nvidia *80 GPU's MSRP has been unreasonable for that long (1080 launched at $600 May 2016, which IMO was already excessive).

But there was a window as recently as fall (3-5 months ago) where you could get most PC parts at MSRP. Granted it was a pretty short window, before the last dying whispers of crypto and COVID induced scarcity were overtaken by the surge of the AI bubble.

I haven't used Signal desktop, but I find Electron apps in general to be very wasteful of system resources. Out of curiosity, I once compared an Electron-based chat app to a C++ alternative, and found that the former used about 25 times the RAM and generated more CPU load.

If GP's system resources are usually dedicated to other tasks, perhaps trying to run an Electron app on top of those led to resource contention, and poor performance. You wouldn't notice this if your hardware is overprovisioned for the things you do with it.

If you have a complaint about your styles being so complicated and in a giant 900 line mega file, I don’t see how you address physical size other than breaking up the file.

Granted, nesting support was also added fairly recently in the grand scheme of things, which boggles the mind given how it was such an obvious problem and solution that CSS preprocessing came about to address it.

Very cool! I imagine it'll be possible to start a static webserver + WebMCP app then use browser as virtualization layer instead of npm/uvx.

The browser has tons of functionality baked in, everything from web workers to persistence.

This would also allow for interesting ways of authenticating/manipulating data from existing sites. Say I'm logged into image-website-x. I can then use the WebMCP to allow agents to interact with the images I've stored there. The WebMCP becomes a much more intuitive way than interpreting the DOM elements

I’m validating an idea and would appreciate feedback from people who’ve sold into mid-market or enterprise companies.

Problem I’ve observed:
In B2B sales, especially complex deals, a surprising number of losses happen because the seller misreads the org structure.

You think you have the decision maker.
You actually have someone with influence but no authority.
The real economic buyer is two layers up.
Or there’s an unseen blocker.

Mapping reporting lines manually using LinkedIn is slow and often guessy. Titles alone don’t reveal power structure.

The idea:
Given a LinkedIn company page, automatically generate a visual org chart showing likely reporting lines and hierarchy depth. The goal is to make “power mapping” systematic rather than intuitive.

Target users:
- SDRs / AEs running enterprise outbound
- Founders doing B2B sales
- RevOps teams inspecting deal risk

What I’m trying to validate:
1. Is misreading org structure actually a frequent cause of deal loss?
2. Do reps systematically map org charts today?
3. Would an automated approach meaningfully change behavior?
4. Is this a workflow tool or just a “nice to have”?

If this resonates and you’d like to be part of a small early group shaping it, I’m collecting a limited waitlist here:

https://www.dealtree.io/

Happy to share more technical details if helpful.

I’d genuinely value critical feedback — especially from people who’ve sold into complex orgs.

You did not ask the same thing. You framed the question such that readers are supposed to look at their current lives and realize nothing is different ergo AGI is lame. Your approach utilizes the availability bias and argument from consequences logical fallacies.

I think what you are trying to say is can we define AGI so that we can have an intelligent conversation about what that will mean for our daily lives?. But you oddly introduced your argument by stating you didn't want to explore this definition...
