You don't need nurses -_-, just your own parents or someone who had kids before and some random books for theoretical questions.

Raising a kid is really very natural and instinctive, it's just like how to make it sleep, what to feed it when, and how to wash it. I felt no terror myself and just read my book or asked my parents when I had some stupid doubt.

They feel like slightly more noisy cats, until they can talk. Then they become little devils you need to tame back to virtue.

It's not entitlement, it's the entire purpose of OSS. You are free to modify, distribute, and profit from other people's code. If you can't do any of these things, then the project is NOT OSS. Simple as that.

Entitlement is when you expect that OSS contributors must provide you with a warranty or a certain feature you need for your business activity. They are not.

The BYD Shark 6 sells for US$40k in Australia:

https://bydautomotive.com.au/shark-6

There's a 100% tariff on top of all the regulatory and political hurdles that prevent BYD from selling in the US, but it shows that a very nice truck can be built for $40k.

You know, ideological differences aside, there are some brass-tacks reasons that this particular brand of rhetoric does you no good, and actually hurts you.

Bought groceries lately? Kind of expensive, no? A significant portion of that is due to the central valley labor shortage. Which is a direct result of ICE enforcement. Same goes for price increases in restaurants across the country. Those increases in prices at the grocery store also translate to inflationary pressure across the board. People have to spend more to eat, so they demand bigger salaries, so their companies raise prices. Not rocket science.

Which makes me wonder - what exactly do you think the value prop is, here? Are you directly benefitting from this or is it just a balm for some vague jingoist need to feel superior? I'm genuinely curious. The common arguments like 'they're importing rapists' is... well I don't even know where to start with that one it's just preposterous and demonstrably false. Immigrants aren't taking your job, are they? Like what is it?
Show HN: DeviceLab – Turn phones across offices into one device lab
by omnarayan | 2025-12-16 08:51:38+00:00
Devices in Bangalore office + SF office + home = one unified lab.

Your APK/IPA, test data, network calls - all flow directly between your machines via WebRTC P2P (DTLS encrypted). We only handle signaling (which device is where).

Setup:

# Machine with phones curl -fsSL https://app.devicelab.dev/device-node/KEY | sh # CI runner curl -fsSL https://app.devicelab.dev/test-node/KEY | sh

NAT traversal via Google/Cloudflare STUN. Fallback relay via Cloudflare TURN (~15% of cases) - still E2E encrypted, they see packets not content.

What this isn't for: - "Test on 100 models" - use BrowserStack - 100% air-gapped (TURN breaks this)

Works with Appium, Maestro, Espresso, XCUITest.

Also open sourced Maestro iOS real device support: github.com/devicelab-dev/maestro-ios-device

https://devicelab.dev | $99/device | First one free forever

Anyone else running multi-location device labs? What broke first?

Thanks! You nailed the intuition! Yes, it shares DNA with Landmark MDS, but we needed something strictly deterministic for the UI. Re: Publishing: We don't have a paper planned for this specific visualisation technique yet. I just wanted to open-source it because it solved a major bottleneck for our dashboard. However, our main research focus at Thingbook is DriftMind (a cold start streaming forecaster and anomaly detector, preprint here: https://www.researchgate.net/publication/398142288_DriftMind...). That paper is currently under peer review! It shares the same 'efficiency-first' philosophy as this visualisation tool

Show HN: Valmi: Outcome-Billing and Payments for AI Agents (Open Source SDK)
by rajvarkala | 2025-12-16 08:53:36+00:00
Hi HN,

I’m one of the builders behind Valmi Value.

After building AI products for a while, we kept seeing the same mismatch: we bill for tokens and usage, while customers care about results.

Valmi is billing and payments infrastructure built for AI agents.

It supports outcome-based and hybrid pricing, with open-source SDKs and a full software stack that’s free to deploy (available under Elastic License).

We are live on Product Hunt too (Upvote helps!). https://www.producthunt.com/products/valmi-io?launch=valmi-v...

Links: https://github.com/valmi-io/value https://value.valmi.io

We’re early and would appreciate feedback and feature requests from people building agentic or usage-based products.

Would be very happy to answer questions.

I wrote more about my hypothesis here: https://www.valmi.io/blog/an-imperative-for-ai-agents-outcom...

Nuclear power is expensive partly because it is bound and tied in endless bundles of regulation and legislation even though going by the statistics it is one of the most safe power sources available. Take away the regulatory burden - which does not mean 'let them do whatever they want', it means 'make sure it is safe and no more than that' - and it will get less expensive rather quickly. Stop treating every single nuclear power plant as a on-off project which needs its own decade-long regulatory approval, replace it with type approved reactor systems and most of those issues disappear.

Nuclear power is expensive because it is supposed to so expensive not to be viable, not because of inherent problems with nuclear power. If the same regulatory burden had been placed on e.g. wind and solar - treat every turbine as a one-off project in need of approval, use land use approval procedures to stall construction, put a turbine blade recycle burden on the turbine owner, etc - those power sources would be just as expensive and unviable. The same goes for coal, oil and gas plants, hydropower installations - which are starting to be treated similarly where I live (Sweden) since the 'green' politicos decided they don't like small-scale power hydro plants - and any other power source. Regulations can make or break a power source, in case of nuclear it seems to be hell-bent on breaking it.

I understand that it's not open source. I just see it as like, a spot where a company that would normally make a closed source product wanted to make it more open and hackable and did actually put the code up and take contributions, which should be a kind of good thing, but it's automatically assumed to be the worst, a rugpull, etc. What if I operated in an ethical gray area right around this pretty reasonably worded term?

That for me has been Dropbox. It's not even a shadow of what it used to be as a sleek, perfect sync tool, but the competition is so bad and getting worse every day (along with Dropbox) that "Dropbox + Cryptomator" is literally the best option I still have. Tresorit seemed to come close, but it's bug-ridden and really sluggish, and their support is painfully useless.

And as someone who has been in Apple's hardware ecosystem for more than a decade now (almost exclusively), I can't in my right mind bring myself to use any of its software/service products (and for good reasons, seeing it go bad to very bad to downright pathetic over the years) except for the OS because that's not really an option. Yes, I do have a small Cryptomator folder syncing to iCloud as well, but that's just because I wanted to have that as a backup sync, and it's a very tiny set of data that I anyway backup to elsewhere.

The bad of it? Yes, keeping everything under one roof really feels simple and easy.

The good? If Apple blocks my a/c today or nukes it, it will take a few hours to few days but I will get back everything single piece of data I have online on a new laptop or phone (Apple or Android or Windows or Linux) - everything! And it's a joy to use specific better/superior options for your software/service needs as per your specific choice!

This is very obviously all generated using AI, borderline slop.

The docs directory is entirely missing. I don’t see how or where the software actually performs any measurements. The readme claims there’s a benchmarking folder but I don’t see that either. So, what methods did you use to measure timing/latency?

Maybe there’s some application for this but I’m not sure what it is. By the time you start parsing those rx bytes from the nic, I have to imagine the numbers start looking closer to DPDK.

In 1921 in Soviet Petrograd (St. Petersburg, then Leningrad, then St. Petersburg again) there was a society called "A house of arts". It was formed by artists, who, among other things, gave lectures on various topics. One of lecturers was a famous Russian poet Alexander Blok. It was a very cold winter and, since the country just underwent a revolution and a civil war, the heating in the lecture hall did not work. The students' headman had to keep the ink bottle on his body so that the ink did not freeze: after the lecture the lecturer had to write down the number of hours in a journal.

On a particularly cold day Blok arrived to the hall and found just a single student, the headman. He very politely asked if the student has the time to listen to the lecture. The student (who later became a writer) assured Blok that indeed he does. And Blok talked for two hours, then made a small break for ten minutes, and talked for two more hours. He then jotted down "History of Western literature, 1 hour", put on his hat and left.

The lecture topic was Servantes and Don Quixote.

~60% of the 8M people that fled Venezuela are incline to support a military intervention, that number goes down to 40% estimated for those still inside, so about more than half the country want external action to get out of the dictatorship. That percentage is for external action, the percentage that voted against the dictator in the stolen election last year was calculated at 76%; so no, is definitely not just the MAGA fan base that want to see something happen.

Hello from one of them, while I appreciate the modernisation (with learnings from Midori as well), and officially going cross platform, it appears that some features are for the sake to keep the team size.

Most of our agency projects that have .NET in them, are brown field ongoing projects that mostly focus on .NET Framework, thus we end up only using modern .NET when given the opportunity to deliver new microservices, and the customer happens to be a .NET shop.

The last time this happened, .NET 8 had just been released, and most devs I work with tend to be journeyman they aren't chasing programming language blogs to find out what changes in each release, or online communities, they do the agency work and go home for friends, family and non programming related hobbies.

Fwiw, we are heavy UMAP users (pygraphistry), and find UMAP CPU fine for interactive use at up to 30K rows and GPU at 100K rows, then generally switch to a trained mode when > 100K rows. Our use case is often highly visual - see correlations, and link together similar entities into explorable & interactive network diagrams. For headless, like in daily anomaly detection, we will do this to much larger scales.

We see a lot of wide social, log, and cyber data where this works, anywhere from 5-200 dim. Our bio users are trickier, as we can have 1K+ dimensions pretty fast. We find success there too, and mostly get into preconditioning tricks for those.

At the same time, I'm increasingly thinking of learning neural embeddings in general for these instead of traditional clustering algorithms. As scales go up, the performance argument here goes up too.
by romanfll | 2025-12-16 08:57:47+00:00
Thanks for your comment. You are spot on, that is effectively the standard Nyström/Landmark MDS approach.

The technique actually supports both modes in the implementation (synthetic skeleton or random subsampling). However, for this browser visualisation, we default to the synthetic sine skeleton for two reasons:

1. Determinism: Random landmarks produce a different layout every time you calculate the projection. For a user interface, we needed the layout to be identical every time the user loads the data, without needing to cache a random seed. 2. Topology Forcing: By using a fixed sine/loop skeleton, we implicitly 'unroll' the high-dimensional data onto a clean reduced structure. We found this easier for users to visually navigate compared to the unpredictable geometry that comes from a random subset

Frankly, using "bad" was a mistake, because it encompasses the two other adjectives. "Your chatgpt-like style is vomit-inducing, bad and boring" <-- you see, why add bad in the middle, you already got that point from the two other insults, right ?

I think if you want to sound less like an AI, you should cut cut cut, and maybe write a bit more like speech, with sort of slangish structures etc, people won't doubt you anymore.

Good luck !

I made Piixes because I kept needing pixel art icons and couldn’t find a large set that was actually free and consistent.

Piixes is a collection of 15,000+ pixel art icons, generated with AI and lightly curated so they all work together. You can use them for personal or commercial projects.

I’ll keep adding more icons over time. If something’s missing, let me know.

Impossible to raid ?

It's definitely much easier and much much cheaper to send a single rocket there blowing the assembled rather large target into still sizeable chucks of orbital debris than it is to deploy and assemble the thing there in the first place. And there are a few terrestrial actors rather capable of this. More than there are who could make it happen under whatever optimistic assumptions anyway.

In itself, a structure of this size in orbit is an efficient catcher of micrometeorites and orbital debris. Over "non-eternal" timeframes you don't even need a bad actor with good rockets.

Nevermind that in such a case, the eventual fate of these sizeable chunks of orbital debris is to become rods of god ... just without particular steerability.

It'd be a sight.

Hey! I'm Alex the creator of TidesDB. I'd like to share the latest major as it's a huge milestone in the development of the open-source project. In recent benchmarks for TidesDB 6 against RocksDB 10.7.5, TidesDB is pulling ahead across most if not all workloads in efficiency and speed. I've written about the design, the benchmarks are available and more. I'd love to hear your thoughts!

That's one way to look at it, mine is no data goes out or in unencrypted, and for me it's simple. Adtech? "No." - let packet kiddies get my home IP address? "No."

It's as simple as that: No thanks, then I slide the slider on WireGuard and then I have an encrypted tunnel that all of my devices can communicate with each other, use a DNS through the tunnel with domains blocked and I can control what phones home and what doesn't. I'm not concerned with foreign governments, snoopy neighbors, war driving, or anything.

I can't solve all the problems but there are no what ifs on my end, *What if" -> No.

I'm not a number in some algorithm or malicious because I route my data securely, I'm a human being.

Yes, that's why I said I don't like their relays. It doesn't even have to be Akamai, you need to trust SimpleX first that not to track your IP. I'd rather use a messenger where something is not possible (or even hard) than trust.

As long as IP leaks are possible, I'd rather also use Signal, where at least the rest is battle tested and state of the art.

My concern with Signal is they'll either comply or move out of the EU with the incoming Chat Control, and I'd rather have a fully decentralized messenger with as few leaks as possible.

That only seems like a solution until the loophole-finders get on with their jobs.

Suppose you own a company and you have a trusted friend. The company, not the owner, enters into a contract with the friend that gives them the right to buy all the company's assets for 1% of their value, if the friend can satisfy a condition that they could only satisfy with the cooperation of the existing owner. Then the owner declares that the company is only worth 2% of its ordinary value -- which might even be an overestimate given the risk that the friend could execute the contract. If the government exercises the option to buy the company, they get a company bound to an obligation to sell all its assets to the friend, and then the previous owner cooperates in satisfying the condition in exchange for the friend giving them the assets back.

"We'll ban that", you say. But then they'll be more subtle about it, and the only way to really catch them is to have a good way of determining the true value of the company, which was the original problem.

You also run into trouble with that one because people can play that game the other way. You have an asset which on paper should be worth around a million dollars, but its value has already been hollowed out or de facto assigned to someone else without actually transferring the asset. Then the owner declares that it's worth $400,000 and the government pays them $400,000 thinking they're going to make $600,000, only to find out that it's actually worthless.

> you were still not fully in control and someone else exploits the economic value without investing

O'Sassy came up recently in one of the forums I lurk in [0], and as discussed there, I tend to agree with Adam Jacob (SystemInit) and others that FSL is definitely one way out but doesn't totally solve the commercialization aspect, because the code & all that IP is still readily available.

Adam, in this talk [1], argues that like RedHat (and unlike Canonical), Open Source businesses must learn to separate source license from distribution license and if they do so, the money is there to be made (in a b2b setting, at least).

> What I have found interesting in the years since is that many companies are wrestling with the same problem, but feel that the two year head start the FSL gives is too aggressive.

... if the companies conflate Open Source and business models, rather it being merely a Go-To-Market (like open core).

Especially true for dev/infra upstarts competing with incumbents (PostHog v Amplitude; GitLab v GitHub [2]), and lately for AI labs (DeepSeek/Qwen/Llama v GPT/Gemini/Claude). In a role reversal, BigTech also uses Open Source to commodotize its competition's advantages (Android v iOS; k8s v Swarm; Firefox/Chrome v IE) [3].

Elegance compared to a PV/Storage facility built next door to a data centre?

It doesn't make sense right now, and won't for at least 5-10 years.

By which time, this current round of hype will have burned up ~$1T if it doesn't fall apart from the current internal contradictions and lack of market/customers/uses.

We're still on the uphill ride of the Gartner hype cycle, not even at the "Peak of Inflated Expectations" yet.

> However, understand the context: the beggar entered a McDonald's and asked clients that were currently eating for money. He got offered the fries of a woman who didn't finish them.

Consider the beggar’s context too. How many times per day/week must they go into that McDonald’s? Leftover fries are probably what they get offered the most. You can accept it a few times, but after a while they provide neither pleasure nor sustenance.

> In my experience, people don't give cash to beggars anymore.

Anecdotally, seems about right.

> But I think many would be open to give food or donate useful objects instead (which they don't have at hand when being begged).

Again, I agree, but I don’t think anyone asks either. One possible workaround would be to donate to your local food bank or another organisation you trust, then when asked by a beggar direct them there. Though that could be another can of worms depending on where one lives.

The anti-cheat streams executable code into the client, and that code is mostly for detecting tampering with the game, injected modules, etc.

Not sure they care about it running in an emulated environment.

They do effectively allocate an executable memory region, copy the machine code that was streamed into it, and jump to it.

I guess in this case the emulation is an actual vm, rather than "rewrite x86 instructions into arm" (don't know much about this subject, but assumed that was how rosetta worked)

On the contrary I think we're low key on the verge of model checkers being widely deployed in the industry. I've been experimenting with Opus 4.5 + Alloy and the preliminary results I'm getting are crossing usability thresholds in a step-function pattern (not surprising IMHO), I just haven't seen anyone pick up on it publicly yet.

The workflow I'm envisioning here is the plan document we're all making nowadays isn't being translated directly into code, but into a TLA+/Alloy/... model as executable docs and only then lowered into the code space while conformance is continuously monitored (which is where the toil makes it not worth it most of the time without LLMs). The AI literature search for similar problems and solutions is also obviously helpful during all phases of the sweng process.
