Ask HN: Looking for a technical co-founder for a digital legacy platform
by officialpage | 2025-10-04 12:12:40+00:00
Hello, there! My name is Avataar

I'm the founder of official.page, a bootstrapped platform for building a digital legacy.

My journey began with a personal discovery—connecting the words "official" and "page" in a browser's address bar revealed an "internal error," which sparked an exploration into the .page TLD and the need for a dedicated online space for everyone's thoughts.

My vision is to create a home where an individual's words, projects, and ideas stay alive and connected over time.

I'm a non-technical founder with a background in marketing and branding, and I've been guiding this project since 2021, starting with a licensed codebase and now working with freelancers to develop a custom design and new features.

I've even been leveraging AI for some of the feature development.

However, the project has reached a point where it needs more than just a series of questions and answers to make it happen—it needs a human touch, a kind of "coding magic" that only a true partner can provide.

I'm looking for a technical co-founder to join me on this journey of exploration and discovery.

This is a non-paid, equity-based role.

I'm seeking someone with hands-on coding skills who is optimistic, believes in the mission of building a lasting digital legacy for others, and is ready to be a true partner in a bootstrapped startup.

If this vision resonates with you, I would love to connect.

Please reply in the comments or find my contact information on this same Hacker News profile to discuss further.

"Brother DCP-T710W Inktank Refill System Printer with Wireless and Automatic Document Feeder" bought on Jul 15, 2019. My order history shows the Inks replacement bought in late 2023, so I must have likely replaced it in 2024. So, roughly 4-5 years-ish.

I think this is the one https://store.brother.ee/devices/laser/dcp/dcpt710w

Hydrogen is the most common element in the universe. So long as you have elemental oxygen, it will react with things and hydrogen is the thing it will react with the most. So having water is almost a given for any Star system. Additionally, protoplanet and cometary collisions are in fact statistically inevitable. The real question is if water can be delivered at a point after enough gravity has amassed to ensure the water stays there.

I will again mention my favorite cancer champions, the bats.

Bats very rarely get cancer (I tried to find the actual # of verified cases of cancers in bats, but came up short), and they have a lot of anti-cancer adaptations in their genome.

They are also really good at taming inflammation and activity of various viruses. That helps them survive infection with rabies - their systems just don't react as aggresively to the infection as ours (and most mammals') do.

This may help them against cancer as well. Not just p53 et al.

Does this mean that probably somewhere below that tower, there were operator stations that would have allowed any of the 5500 lines to connect to any of the other lines? How many simultaneous calls would that even be? Correct me if I borked this, but 5500!/(2^(5500/2)), perhaps?

It seems plausible that if the phone had only just been invented, you'd initially set up small systems that would in fact allow any line to connect to any line. That'd be fine for maybe even a few dozen lines. But as the image shows, that doesn't scale too well.

Yeah Xilinx’s pricing curve is incredibly steep. Probably makes sense since they’re used in things like defence (radar, electronic warfare) so they can sell them in low quantities for huge prices and people will still buy them.

But with decent volume they get pretty cheap - for example there are video converters they have FPGAs in them that you can buy for less than you can buy the FPGA part in single qty - which means the manufacturer of the device is getting the FPGA for 5-10% of list price.
Show HN: Unstable Singularity Detector
by Flamehaven01 | 2025-10-04 12:15:15+00:00
### Why I built

- Earlier this year, DeepMind published groundbreaking work on detecting unstable

singularities in fluid dynamics—one of the deepest open problems in mathematical

physics (arXiv:2509.14185).

- The challenge? No public code. - Extreme numerical precision requirements. - Complex multi-stage training. This makes independent verification nearly impossible. - So I built an open-source re-implementation to bridge that gap.

---

### What It Does

Detects finite-time blow-ups in PDEs using Physics-Informed Neural Networks:

- Lambda prediction formulas (<1% error vs. published methodology) - Automated parameter discovery via funnel inference - High-precision Gauss-Newton optimization (residuals to 10⁻¹³) - Multi-stage training with configurable precision targets

Think: Making century-old fluid dynamics problems tractable with modern ML.

---

### Who This Is For

- Researchers studying singularities in PDEs - Practitioners working with PINNs - Anyone frustrated by non-reproducible ML papers - Students learning scientific machine learning

---

### Built For Reproducibility

- 119 comprehensive tests (all passing) - GPU-accelerated with PyTorch + CUDA - Automated validation CI/CD - Professional documentation + limitations clearly stated - Not just "research code"—designed to actually work in other people's hands.

---

### Current Implementation Status

- Lambda prediction formulas (formula-based validation) - Funnel inference (secant method) - Enhanced Gauss-Newton optimizer (test problem verified) - PINN solver framework - Multi-stage training (framework complete, full validation pending) - Full 3D Navier-Stokes solver (future work) - Transparency matters: This shows exactly what works today vs. what's roadmap.

---

### Links

GitHub: https://github.com/Flamehaven/unstable-singularity-detector

Paper: https://arxiv.org/abs/2509.14185

Documentation: README includes limitations, validation methodology, troubleshooting

---

### Important Disclaimer

This is an independent re-implementation inspired by DeepMind's published

methodology. It is NOT affiliated with, endorsed by, or in collaboration

with DeepMind. Results are validated against published formulas, not

direct comparison with DeepMind's unpublished experimental data.

If you've ever wished "I wish I could just run their code," this is for you.

Contributions, issues, and feedback welcome. Let's make frontier research

more accessible together.

Generally there are never any transfer fees for private individuals doing domestic transfers. The banks just provide that service for free and eat the cost. Businesses wanting to accept payments via the Swish app usually pay a flat rate of the equivalent of approximately USD $0.15 per transaction (exact terms depends on which bank you use).

It's also worth noting that credit card interchange fees are price controlled in Europe; there's a EU directive that caps the interchange fees at 0.2% for debit cards and 0.3% for credit cards. Because of this, cashback on credit cards is pitiful in the EU; you can get 0.5% cashback but not much more than that.

My friend, letting yourself be bothered by this is just pissing into the wind. Humans have been anthropomorphizing machines and other objects for as long as we've been making them, it's a fundamental aspect of human nature. Thousands upon thousands of ships and trains given human names. Tanks, guns, cars, anything that is at least moderately complex or that people find themselves relying on and forming relationships with. AIs have been getting human names since at least 1966 with Eliza, probably earlier, and certainly with many earlier examples in fiction.

There's no stopping it. Just roll with it.

The confusion likely comes from assuming that the U.S. is targeting “cheaper cost of care” as a goal. The target here is “profit for business”. Usually that’s done by businesses withholding wage increases over decades, but occasionally some regulation is canceled or some private capture opportunity is found that jumps profits and prices rapidly. Australian healthcare generates a lower share of private business profit, both per AUD spent on healthcare and per total AUD spent, and so is seen as inferior to the U.S. model by our leaders.

Seen in that light, the increased prices are a universal winner for us: profits go up -> inflation goes up -> GDP goes up. Wages do not go up, and so as a whole we’ve surpassed 25% of all households unable to afford a one-bedroom home. Economists are taught to only model inflation in terms of price level: inflation = profit increases + wage increases, with no way to model their separate impacts. So our policies are economically sound, as long as one disregards the growing poverty.

Despair is, as Demotivators reminds us, highly profitable :-(™
Show HN: BetterSelf – an app to never forget the lessons and ideas you learn
by adamgol | 2025-10-04 12:18:34+00:00
I built BetterSelf to solve a problem I kept running into: most of what we learn, we forget. Books, podcasts, and notes — valuable insights disappear in days.

BetterSelf keeps your best lessons and ideas alive, reminding you over time so they actually stick. I use it every day, and it’s already helped me retain things I would have forgotten.

I’m 19 and built this in about a month while experimenting with personal productivity tools.

I’d love feedback from the HN community — anything you suggest will go straight into the app.

The sub-linked legal document about Frank’s synthetic data generation was quite interesting, specifically how much difficulty their hired consultant (a Data Science Professor) had in creating it.

It can indeed be a tricky problem to do in a manner that’s both fast and accurate, but it’s absolutely possible once you have the right datasets, which aren’t even that large. U.S. ZIP codes, telephone area codes (with enough out-of-place ones to mimic people who’ve moved and kept their cell phone number), common names, and a word list will get you rows that look plausible. Matching street addresses requires a much larger dataset, but again, it’s not impossible.

And of course if your input form gives the user any help when they are filling it out, then you can run in to a problem where users choose ABBA more often than Aerosmith or Argent, (more often than they would have), based just on how ABBA is presented first alphabetically.

I got around this issue by not giving any help; the user was presented with a form with blanks for five artist and song name pairs. Which resulted in a crazy amount of typos, which I fixed “by hand” using a pretty lame interface since I wasn’t a good enough programmer to create a better way in 1996. I spent a LOT of time correcting typos.

Most of the things you’re describing he “can’t” do, but his party won’t impeach him and the Supreme Court is complacent if not intentionally incompetent.

You can bet, with 100% certainty, the standard will change for a democratic president. There’s a reason half the shit he’s doing is being decided on the SCOTUS shadow docket and it’s because they want to be able to tell a Democrat no for doing the same thing in the future.

> Uber didn't invent anything

They didn't. They innovated, practically implemented ideas that resulted in the introduction of new goods and services [1]. This is a meaningful difference.

Uber didn't invent anything. But they did pull ridesharing out of a hat.

The fact that Bezos is saying this is precisely why the commenter is asking this. He clearly stands to benefit massively from the bubble. Statements like this are meant to encourage buy-in from others to maximize his exit. Presumably "rich" refers to those, like Bezos, who already have incredibly disproportionate wealth and power compared to the majority of people in the US. I'm honestly not sure what the thrust of your comment even is.

You'd think that at least initially, individual towns would stand up fully connected (albeit small) but isolated networks. That before very long, the idea of connecting one town to the next would occur, and it would be realized that you only need a relatively small number of "long distance" lines, connected between the existing switchboards. At which point, if you were wiring up a city, you'd follow that pattern; tiered layers, as you say. It stands to reason then, that Stockholm's system must have started very early, and had absolutely explosive growth, to get to a situation like that tower.

All the smartest people I know in finance are preparing for AI to be a huge bust that wipes out startups. To them, everyone in tech is just a pawn in their money moving finance games. They view Silicon Valley at the moment salivating on what there plays are to make money off the coming hype cycle implosion. The best finance folks make the most money when the tide goes out… and they’re making moves now to be ready.

Take that for what it is.

Now we’re getting into territory for vigorous debate and arming ourselves toward moral outrage.

At what point are we subjecting our own flesh to the insanity of bit banging from conception until death?

Is this enslavement?

Do we care?

Lack of modern coherence demands a group search for Objective Morality. A line we will not let crossed: the sacrificing of those “innocent” for “power”. Anyone (now a person? Or do we call those “subjectives?”) who cannot say “no”, cannot “walk away or stand their ground”, and does not have an exclusive right to their own persons (embodiment) are having their “human” rights violated.

Or something like that.

We have that in canada and it does not work that way at all. Single payer turns into a big en(ugh line item that there is political "otivation to limit supply and it all goes to crap just in a different way than it has in america. The solution is way simpler: ensuring there is enough supply that price raising bs fails. That gives you a bunch of different ways to get to the solution that will all work vut they all have ensuring enough supply to limit shenanigans at their base.

The shareholder class would demand rapid fire exploitation of © the moment it expired and the resulting media would be a soup of mediocrity. The idea is to recognize the highly creative have unique imaginations that invent paradigms that propel culture. Excluding that for 70+ years generates that. Had Lucas gained the rights to Flash Gordon (DeLaurentiis beat him to it) he'd never been forced to create the SW universe. Think about constraints as the path to progress.

Video description, from the Velcro brand YouTube channel:

Our Velcro Brand Companies legal team decided to clear a few things up about using the VELCRO® trademark correctly – because they’re lawyers and that’s what they do. When you use “velcro” as a noun or a verb (e.g., velcro shoes), you diminish the importance of our brand and our lawyers lose their insert fastening sound. So please, do not say “velcro shoes” (or “velcro wallet” or “velcro gloves”) - we repeat “velcro” is not a noun or a verb. VELCRO® is our brand. #dontsayvelcro

I’ve been reading a lot lately about the negative effects of inflammation. Recently, I came across an article arguing that it’s inflammation in the blood vessels (not cholesterol itself) that causes cardiovascular problems.

Now this article blaming inflammation for cancer.

But isn’t inflammation also a useful and necessary process in the body? If it’s so harmful, should we all be taking anti-inflammatory drugs? Of course, those have their own downsides too (my doctor mentioned that ibuprofen can even affect hearing).

We can decriminalize being a sex worker without decriminalizing johns, pumping, or brothels. Rather like some places have decriminalized the possession of small amounts of drugs, but not the sale.

That makes it safer for women and girls who are being exploited to report the people exploiting them and to escape to a healthier life, while still making it straightforward to punish people who exploit, traffic, and abuse them.

> we all should hope

If you're serious about anything, you do more than hope. You do diligence on your prospective employer before going to work for them. You think through a litany of contingencies and prepare a plan of action for each. Jobs in this industry are uniquely amenable to this by virtue of their relatively higher compensation and the autonomy often afforded to employees. If you spend an hour every day on HN, you can spend an hour meditating upon your conscience.

Predicting one's response to stressful and unexpected circumstances is hard. So try to anticipate circumstances and cultivate relevant virtues in advance.

If you think about it enough, most industries are doing terrible things. Work for an auto company? Thanks for the CO2 emissions accelerating climate change. Work for a consumer manufacturer? Thanks for the plastic waste choking oceans and landfills. Defense contractors? Thanks for enabling wars and killing innocents. Banks? Thanks for enslaving folks to debt and perpetuating economic inequality. Tech giants? Thanks for surveilling billions and eroding privacy on a massive scale. Social media platforms? Thanks for amplifying misinformation and fueling mental health crises. Fast fashion? Thanks for exploiting sweatshop labor and polluting waterways with toxic dyes. Pharma companies? Thanks for price-gouging drugs and prioritizing profits over access. Oil and gas? Thanks for fracking communities into environmental ruin and lobbying against renewables.

Almost everyone is contributing to terrible activities. Just different degrees of bad.

Here's another thing to think about: if you are in IT ops, you might have access to private data that could be requested, without proper judicial review, by a three letter agency. When you receive a National Security Letter with a gag rule attached, how will you react? What action can you take that is both legal and also ethical?

Because it is not just bosses that might try to pressure you into taking unethical actions, it is also the state itself.

For my part, I have a plan, and I've told my boss enough to trust him to read between the lines and revoke my access to make it impossible for me to turn over customer data without a warrant.

There is a hard limit on the number of atomic elements, and an even smaller limit on the number of soluble compounds that facilitate chemical reactions, and water is demonstrably both the best and the most common in the universe.

So while it may be possible for life to exist without water, any alternatives should be reasonably expected to be even more rare than water-based life
Ask HN: Systems Development Path

I'm interested in learning to develop more complex low-level systems. I thought about starting by learning database systems. I know how they work, having experience dealing with distributed systems and databases, and I have written some patches for considerably large databases here and there.

I have started by giving this course a try: https://skyzh.github.io/mini-lsm/ , but I'm feeling it is overwhelming and extremely difficult. For instance, this is the "official solution" for the 1st day exercise:

fn freeze_memtable_with_memtable(&self, memtable: Arc<MemTable>) -> Result<()> { let mut guard = self.state.write(); // Swap the current memtable with a new one. let mut snapshot = guard.as_ref().clone(); let old_memtable = std::mem::replace(&mut snapshot.memtable, memtable); // Add the memtable to the immutable memtables. snapshot.imm_memtables.insert(0, old_memtable.clone()); // Update the snapshot. *guard = Arc::new(snapshot); drop(guard); old_memtable.sync_wal()?; Ok(()) }

There are many folds of complexity and things you have to be aware of to write such a good solution. Rust concurrency primitives, COW state updates, subtle ownership moves (std::mem::replace) to avoid cloning big things, lock complexity, etc.

I know enough C++ to read and contribute to big and complex projects, but probably not enough to write a project on my own. Rest aside, it's my first time reading/writing Rust.

All this explanation to the real question...

Does it make sense to keep grueling this tutorial by approximating it like the following: 1) try to write the code on my own, 2) go to the solution to discover everything I did wrong, and 3) invest as many hours as necessary until I understand what every single line of the solution does.

Or does it make more sense to start with something a bit lighter, where I'll still learn a lot without all this suffering?

Sure. But you'll be transferring the entire file everytime.

The advantage of sqlite3_rsync is that, if on the other end is an SSH server with sqlite3_rsync, you only transfer the changed pages, and still get a “perfect” copy of the file on the other end.

The advantage of Litestream is that on the other end does not need to live a “server,” and still only changes are uploaded. If you do it continuously, you get many points to recover from, and many of those cross reference each other, saving storage space too. On the flip side, you need the tool to restore.
