Show HN: Netcards – PWA for exchanging contacts at events via QR codes
by evronm | 2025-11-18 16:59:40+00:00
I don't use business cards, preferring to let people scan a QR code from my phone. There are, however, 2 issues:

- Other people tend to give me business cards and they end up in an undifferentiated pile

- When people scan my QR code, the info goes into their contact, never to be seen again.

To address this, I created netcards. It's a dead simple PWA that I vibe coded with Claude. The workflow is as follows:

- Enter your info and an event name into the "My Card" page and save it. A QR code appears.

- Set up tags on the tags page

- When people scan the code with their phone's app, it goes right into their contacts black hole, but at least there's an event name there and all your info.

- If you scan app to app, you can select tags, which you can later filter on along with the event name.

- You can then share contacts, generate QR codes for them, or save the vcards for import into your native contacts app.

Obviously, the more people use this, the more useful it becomes, so I figured I'd start by sharing it with HN.

Tech: - Vanilla JavaScript, PWA with offline support

- IndexedDB for local persistence

- jsQR + qrcodejs for scanning/generation

- Bulma CSS, all dependencies from CDN

- Live at https://netcards.app

GitHub: https://github.com/evronm/net-cards/

I've tested this on my Android phone only, so I'm particularly interested to hear from iPhone users about their experience. But in general, I'd like to know if people find this useful and if anyone has any suggestions.

> Neither engenders user trust in the work that the agent undertook. Antigravity provides context on agentic work at a more natural task-level abstraction, with the necessary and sufficient set of artifacts and verification results, for the user to gain that trust.

I'm going to need an AI summary of this page to even start comprehending this... It doesn't help that the scrolling makes me nauseous, just like real anti-gravity probably would.

I unlocked my phone the other day and had the entire screen taken over with an ad for the Gemini app. There was a big "Get Started" button that I almost accidentally clicked because it was where I was about to tap for something else.

As an Android and Google Workspace user, I definitely feel like Google is "pushing their AI into everything they can", including the Gemini app.

> We are mincing words.

Good point.

These words are unfortunately loaded. "instrumentalizing" is so close to "instrument" for me to see them as unrelated in meaning. But lots of similar words drift in meaning, or have several interpretations.

I don't have any issue with people doing things for "natural" reasons, vs. realpolitik analytical reasons, when the motive is still benefit-neutral, or benefit-benefit relative to ourselves-others.

I think it's the same everywhere. I'm in North America, I drive a normal size car, between the super bright led lights, and trucks and SUVs with higher mounting points it's getting really bad. I'm now almost unable to tell when people still have their high beams or not. Add to that some people who don't give a damn and actually drive with high beams on, and you're certain to become blind.

I saw her last few talks at VCFeast. Always extremely engaging to hear from someone with as much skill and knowledge as her. Amazing to hear how she built her own debugger for the (i believe, i have the memory of a goldfish) Atari 2600. I always tried to catch her talks if possible, if just to get a glimpse of what the past looked like. I'm going to miss having those to look forward to.

RIP

Yeah, it seems like most people assume there is a reach and scope of taxation that isn't really possible. Wealth can be expatriated, it can be in non-fungible objects (paintings, &c), it can be in goods held in common such that no transfers occur (for example, a house that people live in together and jointly own).

There isn't anywhere an index or lookup table of all legal rights a particular person has to wealth (or, in truth, to "things", since anything can be worth something and contribute to wealth). There are things they may have a right to that they don't even know about.

Modern Ubuntu is a laughable example with a lot of untested Rust components added just for the sake of some big corporations.

Defining better OS is almost as complicated as defining better philosophy. Somebody is leftist, somebody is rightist you know what I mean. When you see what's better usually you can not unseen it.

For me Woedows 7 can give:

1. years of uptime (still with regular browsing! and with using S-states!);

2. native support of god-like NTFS, all my personal backups has it;

3. better support on laptops, for example just try to ditch the UnneededD (Devuan) and you are going to say buy-buy to predictabrle S-states, stable USB performance when using multiple devices and who knows what else;

4. the best battery time among all the market;

5. some old hardware like ATI videocard can not be run on modern kernell, also some old hardware like my digital oscilloscope, my friend's digital syntheiser - all of that makes me not just use but love he Bill Gate's crap. You don't even tied to any version of your appreciated Debian.

6. A lot of industry-best software at least requires me to have Wine. Foobar as the best audio player, STDU as the best book reader, Viktoria as the best HDD tester etc. I have a terabyte of music, hundreds gigs of books and dozens of external disk drives, consuming all of that is my typical non-work activity.

7. I also still use it for my daily job which involves using Internets. No viruces gotten, no unexpected behaviour observed, just working.

Not affiliated, just thought it was a neat idea when I stumbled upon it during some hobby weather research last year:

ForecastAdvisor will show you the accuracy of the major weather forecasters, including AerisWeather, Foreca, Microsoft, the National Weather Service, OpenWeather, The Weather Channel, Wetter.com, WeatherBit, World Weather Online, and others. They also provide links to your city's weather forecast from all the other weather forecasters, so you can compare for yourself.

It is not a right, for sure. However, there are historical reasons why they are county wide quotas. Before the 1965 INA (Hart-Celler Act, which JFK wanted), they had a national-origins quota system: each country's quota was based on the existing immigrant population of that national origin already in the United States, using data from the 1890 census. Because the U.S. population in 1890 was overwhelmingly from Northern and Western Europe (especially Protestants), this formula strongly favored those groups. Immigration from Southern and Eastern Europe was heavily restricted because most of them are Catholics. Once Catholics got political power, thanks to JFK, this is reformed in favor of what we see country based caps.

The national-origins formula was explicitly designed to maintain the existing ethnic composition of the U.S.--in other words, preserve what policymakers at the time considered the “traditional” American demographic makeup.

It's not a poem that _I_ wrote. That would be silly. You don't have to share _my_ feelings.

It's inscribed on a plaque at the base of the Statue of Liberty and is taught in civics classes as a representation of American values. The idea is that, when you live in a society, you build upon a set of shared values and stories so that you can have something in common with your neighbor and something bigger than yourself to strive for.

All that said, there's a reason that comes last on my list of reasons. If you and I agree on the shared story, the other stuff doesn't matter so much. If we don't, having pragmatic and fiscal reasons to get on the same page lets us at least stay rational in our discourse.

If illegal aliens are not "subject to the jurisdiction thereof," it's not possible to arrest them for a crime--that's what the phrase means.

The language excludes diplomats, foreign soldiers on US soil while they're fighting a war with the US, and (given the context of when the amendment was passed) Native Americans who hadn't yet been told that they were subjects of the US.

It’s…a VSCode fork? Really? What has become of Google? Ten years ago, when I was getting into the world of software, there was still an aura about them. They built everything in this huge monorepo, and it worked. They were this deeply technical company for whom it seems anything could be done.

And now they can’t even ship a desktop app without forking VSCode? Look, I get it. There’s this huge ecosystem. Everyone uses it. I’m not saying it’s damning or even bad to fork it.

But why is this being painted as something revolutionary? It’s a reskin of all the other tools which are variations on the same theme, dressed up in business speak (an agent-first UX!). I’m sure it’s OK. I downloaded it. The default Tokyo Night theme is unusable; the contrast can’t be read. I picked Vim bindings, but as soon as I tried to edit a file I noticed that was ignored.

What happened? Is this how these beautiful, innovative companies are bound to end up?

Arguably it had a great deal to do with what we think of as a "virtual machine."

Virtual 8086 remapped all opcodes and memory accesses to let a program pretend to be on a single, real-mode 8086 when in reality it was one of many programs running in protected mode on a newer chip

AMD-V and whatever the Intel counterpart is do the almost exactly the same thing: re-map all ia32 and amd64 instructions and memory accesses to let a program pretend to be doing ring 0 stuff on an x86 box, when in reality it is one of many programs running with fewer privileges on a newer chip

There are a few more wrinkles in the latter case -- nested page tables, TLB, etc -- but it is the same idea from the viewpoint of the guest.

> I think the idea the future lives have value, and the value of those lives can outweigh the value of actual living people today is extremely immoral.

This is an interesting take. So if we found out for certain that an action we are taking today is going to kill 100% of humans in 200 years, it would be immoral to consider that as a factor in making decisions? None of those people are living today, obviously, so that means we should not worry about their lives at all?

I can't believe these "smooth scrolling" scripts are still a thing. I was wondering why I was having a hard time scrolling the page on my phone, when I got to my PC and felt the reason.

It's incredible to think how many employees of this world-leading Web technology company must have visited this site before launch, yet felt nothing wrong with its basic behavior.

Well said. (I too want that.) I found my first reaction to `MutableArray` was "why not make it a persistent array‽"

Then took a moment to tame my disappointment and realized that the author only wants immutability checking by the typescript compiler (delineated mutation) not to change the design of their programs. A fine choice in itself.

Lol. Windows already is malware. Anyone who's running Windows is fundamentally fine with not being in control of what's happening on the computer they're using.

Upvoted anyway. People should be aware of the ancillary risks of pointing Redmond's loaded gun at their own head, even if they accept the inherent risks to doing such.
by foobarchu | 2025-11-18 17:04:59+00:00
Absolutely. They have dramatically worsened the world, with little to no net positive impact. Nearly every (if not all) positive impacts have an associated negative that that dwarfs it.

LLMs aren't going anywhere, but the world would be a better place if they hadn't been developed. Even if they had more positive impacts, those would not outweigh the massive environmental degradation they are causing or the massive disincentive they created against researching other, more useful forms of AI.
by big-and-small | 2025-11-18 17:05:00+00:00
Everything is about context. When you just ask non-concrete task it's still have to parse your input and figure what is tic-tac-toe in this context and what exactly you expect it to do. This is why all "thinking".

Ask it to implement tic-tac-toe in Python for command line. Or even just bring your own tic-tac toe code.

Then make it imagine playing against you and it's gonna be fast and reliable.

Just as I haven't seen it mentioned yet, one thing that makes British roads worse at night nowadays is a lack of maintenance on the "cat's eyes" reflectors that used to line every major road. They are now quite often missing or broken but previously gave you a clear outline of the road for some distance even with dipped headlights. Same goes for signage overall - standards have slipped.
by NaomiLehman | 2025-11-18 17:06:12+00:00
they are not meaningless, but when you work a lot with LLMs and know them VERY well, then a few varied, complex prompts tell you all you need to know about things like EQ, sycophancy, and creative writing.

I like to compare them using chathub using the same prompts

Gemini still calls me "the architect" in half of the prompts. It's very cringe.

Based on my benchmarks (run 100s of model generations).

2.5 stands between GPT-5 and GPT-5.1, where GPT-5 is the best of the 3.

In preliminary evals Gemini 3 seems to be way better than all, but I will know when I run extended benchmarks tonight.
by adastra22 | 2025-11-18 17:07:06+00:00
Maybe if you confirm to its expectations for how you use it. 4.5 is absolutely terrible for following directions, thinks it knows better than you, and will gaslight you until specifically called out on its mistake.

I have scripted prompts for long duration automated coding workflows of the fire and forget, issue description -> pull request variety. Sonnet 4 does better than you’d expect: it generates high quality mergable code about half the time. Sonnet 4.5 fails literally every time.

I've known several people who've done it. I wasn't trying to argue that there isn't a lot of manual labor going on. But I'm doubting how much of that labor extends beyond interfacing with the applicant.

Are they interviewing references outside the country? Doing deep background checks that are not basically instant electronically? That's what I'm talking about. The denial process can probably be made extremely fast, and then the tedious interview part can be focused only on the ones we are planning to accept otherwise.

It's not that great even if you have money. Unless you're talking about the type of money needed to pay for all of your treatments out of pocket, and give you access to special private care most people don't even know exists.

My experience has been: if you have an immediate health issue with an obvious solution, you can get pretty good care. Say if you have a broken arm, gun shot wound, heart attack, stroke, etc. Anything uncommon, or that requires ongoing care, is a life sucking nightmare.

I'll give some examples from my own life. I live outside a major metropolitan area. A relative was visiting me and had a stroke in my living room. I called 911, and an ambulance appeared 5 minutes later, in 25 minutes they were in a hospital with a telemedicine link to a stroke expert. The expert said they needed to be brought to a downtown hospital so they were sent there by helicopter. One of the two best neurosurgeons in the city performed an endoscopic removal of the clot and saved their life.

Contrast this with a different relation who struggles with chronic pain and spine problems and has spent the last 20 years bouncing around various doctors, battling insurance companies, pharmacies, waiting to be seen, waiting endlessly for specialists, tests, and having to keep track of all of their information themselves because the system is fragmented and every office wants a complete restatement to their medical history.

>> Executive orders cannot overrule the Constitution.

> I would hope this is a fairly universally held position, not so partisan.

I agree. I think the constitution limits both the executive and the legislative branches.

> how will they feel if the next administration decides to pull the same stunt with the 2nd?

The 2nd amendment has already been overridden by federal laws without a constutional amendment.

The 2nd used to mean that the states has a right to let their citizens arm themselves privately with military weapons. The federal government was forbidden by the 2nd to interfere with this.

I'm from Europe and fine with the very restrictive licensing we have here.

But it looks very shortsighted to wildly re-interpret the constitution far outside of the original meaning, instead of passing new amendments.

I'm pretty sure they mention in their various TOSes that they don't train on user data in places like Gmail.

That said, LLMs are the most data-greedy technology of all time, and it wouldn't surprise me that companies building them feel so much pressure to top each other they "sidestep" their own TOSes. There are plenty of signals they are already changing their terms to train when previously they said they wouldn't--see Anthropic's update in August regarding Claude Code.

If anyone ever starts caring about privacy again, this might be a way to bring down the crazy AI capex / tech valuations. It is probably possible, if you are a sufficiently funded and motivated actor, to tease out evidence of training data that shouldn't be there based on a vendor's TOS. There is already evidence some IP owners (like NYT) have done this for copyright claims, but you could get a lot more pitchforks out if it turns out Jane Doe's HIPAA-protected information in an email was trained on.

Well, I tried a variation of a prompt I was messing with in Flash 2.5 the other day in a thread about AI-coded analog clock faces. Gemini Pro 3 Preview gave me a result far beyond what I saw with Flash 2.5, and got it right in a single shot.[0] I can't say I'm not impressed, even though it's a pretty constrained example.

> Please generate an analog clock widget, synchronized to actual system time, with hands that update in real time and a second hand that ticks at least once per second. Make sure all the hour markings are visible and put some effort into making a modern, stylish clock face. Please pay attention to the correct alignment of the numbers, hour markings, and hands on the face.

I have my own private benchmarks for reasoning capabilities on complex problems and i test them against SOTA models regularly (professional cases from law and medicine). Anthropic (Sonnet 4.5 Extended Thinking) and OpenAI (Pro Models) get halfway decent results on many cases while Gemini Pro 2.5 struggled (it was overconfident in its initial assumptions). So i ran these benchmarks against Gemini 3 Pro and i'm not impressed. The reasoning is way more nuanced than their older model but it still makes mistakes which the other two SOTA competitor models don't make. Like it forgets in a law benchmark that those principles don't apply in the country from the provided case. It seems very US centric in its thinking whereas Anthropic and OpenAI pro models seem to be more aware around the context of assumed culture from the case. All in - i don't think this new model is ahead of the other two main competitors - but it has a new nuanced touch and is certainly way better than Gemini 2.5 pro (which is more telling how bad actually that one was for complex problems).

Why? There's nothing wrong with metaphor.

And agentic coding is about working at a much higher conceptual level. Further from the ground. Antigravity is a functional metaphor.

My only issue with it is that it's too long at five syllables, and "anti-" is an inherently negative connotation. I'm guessing this will eventually get renamed if it gets popular, much like Bard was.

> Thanks for the detailed answer, I think that'll be a relief for many. However, would you say this still is a volatile situation for people who are facing this issue? Are the rulings _final_ on this? Or is there chance of people getting stuck in limbo?

No, rulings are not final. SCOTUS could and very well may disagree with more than a hundred years of jurisprudence and overrule e.g. US v. Wong Kim Ark[1], enabling much easier denaturalization by the federal government. Here's an example article from a right-wing think tank about why they believe SCOTUS should overrule Ark[2].

The problem is that they react to lights from the opposing vehicle, but they are going to hit your eyes before they detect your lights.

That's with simple high beam assist. The matrix ones you refer to actually have another feature which makes things even worse; they progressively dip the light in parts, but combined with the first effect this means that you have a few seconds of being blinded before all of their component leds have been dipped.

Not to mention that they are only reacting to something directly in front of them for the most part -- meaning you can be blinded on curves, or when turn around and looking at them off axis (say as they wait to turn into a road).
