Yes, Chromium has "native" sandboxing on all those platforms, Windows [0] Linux [1] and MacOS [2].

Chromium uses both seccomp filtering as well as user namespaces (the technology that Docker/Podman use).

The Windows and MacOS sandboxing strategies are more "interesting" because I've seen very few (open source) programs that use those APIs as extensively as Chromium. On Windows, it makes use of AppContainer [3] (among other things), while on MacOS it uses the sparsely documented sandbox API [4], which I think was based on code from TrustedBSD?

(Apologies for the TeX below - the formula is too complicated for HN. There is a mouse on page 13 - see the pdf.)

Abstract: "We discuss how to write down three specific natural numbers $A$, $B$, $C$ such that for any real number $r$ you've probably ever thought of, it is consistent with \ZFC{} set theory that $r = \log(\sup_{x_0,x_1 \in \Rb} \inf_{x_2 \in \Rb} \sup_{x_3 \in \Rb}\allowbreak\inf_{x_4 \in \Rb}\sup_{m \in \Nb}\inf_{n_0,\dots,n_{A} \in \Nb} x^2_0 [(n_0 - 2)^2 + \allowbreak(n_1-m)^2 + n_2 + (n_B - n_C)^2 + n_3 \sum_{k=0}^4 ( x_k - \frac{n_{k+5}}{1+n_4} + n_4)^2 + \sum_{i,j = 0}^B (n_{9+2^i3^j} - n_i^{n_j})^2])$. We also discuss why it's possible, assuming the existence of certain large cardinals, for there to be a real number $s$ which cannot be the value of this formula for our particular $A$, $B$, $C$. This involves set-theoretic mice."

Meh, he’s been very fairly calling out AI companies for over-promising and under-delivering, along with critiquing the idea that training LLMs on bigger data will solve AGI.

He’s vocal and perhaps sometimes annoying, but who cares. A number of his articles have made great points at times when people are loosing themselves with hype for AI. Reality is somewhere in the middle, and it’s good to have more people critiquing what AI companies are doing. Who cares if a lot of the blog posts are short and not that interesting.

Don’t forget that captain of the plane makes decisions not Elon.

If captain of the plane disobeyed direct threat like that from a nation, his career is going to be limited. Yeah Elon might throw money at him but that guy is most likely never allowed again to fly near any French territory. I guess whole cabin crew as well .

Being clear for flying anywhere in the world is their job.

Would be quite stupid to loose it like truck driver DUI getting his license revoked.

> As someone who generally stays out of politics, I didn’t know much about the incoming administration’s stance towards tariffs, though I don’t think anyone could have predicted such drastic hikes.

I have an appreciation for very bright lamps, and the project is neat, but that stuck out to me.

I'm always fascinated by people who both feel comfortable ignoring maybe the single most impactful society-determining apparatus but will also say "no one could have seen that coming", where that is whatever they were unaware of because they chose to check out. I find the stance so fascinating because for myself, it would be impossible to not try and understand why the world is the way it is.

Everything is downstream of politics whether people want to recognize that or not, and choosing to ignore it is, in fact, a political choice.
Show HN: I built an AI twin recruiters can interview
by Charlie112 | 2026-02-03 23:19:28+00:00
https://chengai.me

The problem: Hiring new grads is broken. Thousands of identical resumes, but we're all different people. Understanding someone takes time - assessments, phone screens, multiple interviews. Most never get truly seen.

I didn't want to be just another PDF. So I built an AI twin that recruiters can actually interview.

What you can do:
•Interview my AI about anything: https://chengai.me/chat
•Paste your JD to see if we match: https://chengai.me/jd-match
•Explore my projects, code, and writing

What happened: Sent it to one recruiter on LinkedIn. Next day, traffic spiked as it spread internally. Got interview invites within 24 hours.

The bigger vision: What if this became standard? Instead of resume spam → keyword screening → interview rounds that still miss good fits, let recruiter AI talk to candidate AI for deep discovery. Build a platform where anyone can create their AI twin for genuine matching.

I'm seeking Software/AI/ML Engineering roles and can build production-ready solutions from scratch.

The site itself proves what I can do. Would love HN's thoughts on both the execution and the vision.

All that you say is true in a world (or for product categories) that has reached a technological plateau.

The point about household appliances that I was trying to make wasn't about individual appliances decaying (= breaking down), but about the utility of a model decaying over time, as it e.g. becomes uncompetitive because it has worse energy efficiency than it's modern counterparts (or in the case of refrigerators uses harmful greenhouse gases).
by PostOnce | 2026-02-03 23:19:57+00:00
If it turns out that AI isn't much more productive, it could also turn out that people still believe it is, and therefore don't value software companies.

If that happens, some software companies will struggle to find funding and collapse, and people who might consider starting a software company will do something else, too.

Ultimately that could mean less competition for the same pot of money.

I wonder.

There are no pure CRUD engineers unless you are looking at freelance websites or fiver. Every tiny project becomes a behemoth of spaghetti code in the real world due to changing requirements.

> The world is relatively satisfied with "software products".

you can delete all websites except Tiktok, Youtube and PH, and 90% of the internet users wouldnt even notice something is wrong on the internet. We dont even need LLMs, if we can learn to live without terrible products.

There are people literally working on accomplishing this. I don’t understand what’s with the arrogance and skepticism.

Edit: Not trying to single out the above commenter, just the general “air” around this in all the comments.

I honestly believed folks on HN are generally more open minded. There’s a trillion dollar merger happening the sole basis of which is the topic of this article. One of those companies put 6-8,000 satellites to space on its own dime.

It’s not a stretch, had they put 5 GPUs in each of those satellites, they would have had a 40,000 GPU datacenter in space.

Its not.

If you call 119 it gets assessed and potentially forwarded to the right department, which then assesses it again and might (quite likely will) trigger an inspection. The people who turn up have broad powers to seize children from the home in order to protect them from abuse.

In general this works fine. Unfortunately in some circumstances this does give a very low skilled/paid person (the inspector) a lot of power, and a lot of sway with judges. If this person is bad at their job for whatever reason (incompetence/malice) it can cause a lot of problems. It is very hard to prove a person like this wrong when they are covering their arse after making a mistake.

afaik similar systems are present in most western countries, and many of them - like France - are suffering with funding and are likely cutting in the wrong place (audit/rigour) to meet external KPIs. One of the worst ways this manifests is creating 'quick scoring' methods which can end up with misunderstandings (e.g. said a thing they didn't mean) ranking very highly, but subtle evidence of abuse moderate to low.

So while this is a concern, this is not unique to France, this is relatively normal, and the poster is massively exaggerating the simplicity.

Like a lot of people I think I hold a mental image of "jet" which is actually not helpful for a modern engine. All modern jets seem to have this massive rotational component, the turbine, and the fan outside the turbine chamber. so does a turboprop. And the basic propeller before that. Oh, the "fan" has more blades. Pshaw! a spitfire went from 3 blades to 5 across it's lifetime. post-spitfire engines had contra rotating props with many more blades. It can't just be about the NUMBER of blades can it?

So, there is the turbine. Is that directly coupled to the "fan" bit? If not, it's probably a turboprop, but even then I am unsure all visible fans on modern jets on the spool couple directly to the turbine.

The "jet" part is the combustion chamber. Everything else, you might as well consider turbines and propellers as "the same kind of thing" but then you're in a pub arguing which details make one a prop and the other a fan.

If you like Roger ramjet you're in the other kind of Jet: the one which is more like a rocket. Also, if you work in government service how are you passing the drug test with those proton energy pills?

Frank Whittle's biography is a great read. He had some hair raising moments. things OSHA would not be happy about.

Hey HN! I'm the builder here.

If you're interested in the full story and more details, I also wrote about this on LinkedIn: https://www.linkedin.com/posts/charlie-tianle-cheng-6147a432...

The technical implementation treated the iteration process like training a model: test the AI's responses, measure the "loss" against what I wanted, backpropagate by adjusting prompts/RAG/CRUD, and repeat.

Happy to answer any questions about the tech stack, the AI architecture, or the broader vision!

The Zapotec civilization pre-dates the Aztecs and Maya and were the first to develop a writing system in Mexico.

Benito Juarez, President of Mexico during their revolution, was Zapotec.

The Zapotec people are still around today and a large number still speak their ancient language. A large number moved to LA and another group in New Jersey, but they're all over the US.

Mu is awesome, one of my favorites. I especially like the "Mu and More" and "Mu and Much More" decks that have other games you can play in the box. It is a bit fiddly customizing the decks for the different games, but it is amazing how much game is in that one box. Njet was mentioned in another comment, and that is one of my go-to games when playing with non-gamers.

Mu is my favorite trick taking game of all time, but it is difficult enough that I don't get a chance to play it very often.

Yup, DINUM does support the Matrix Foundation, which is appreciated in terms of helping keeping Matrix itself alive and independent.

However, this doesn't help support the folks improving & maintaining Element (either its clients or servers), which is the actual upstream product that Tchap is dependent on. Just like donating to the W3C doesn't help improve Firefox, if you were operationally dependent on a Firefox fork.

I can assure this author: strapping a company that lights money on fire (today, maybe not tomorrow) to a cash flow enterprise makes the IPO harder, not easier, in the absence of credible plan. The market speculates, but it’s not being completely irrational. I’d actually be surprised if we didn’t have factories or data centers in space one day.

> nukes are not magic. Explain to me how you imagine the series of events where Paris uses their nukes to get the USA to extradite Elon to Paris

Paris doesn’t need to back down. And it can independently exert effort in a way other European countries can’t. Musk losing Paris means swearing off a meaningful economic and political bloc.

IMHO the previous race ended because there wasn't that much to be achieved with the technology at hand at that time. They just pivoted to space stations, a space(!) with low hanging fruit.

So if US ends up beating China on this, it will all depend if there's something feasible to do next. I'm under impression that everything done in this new space age so far is just a re-do with the cheaper and better technology. SpaceX reaping that but I am not sure if there's any drastically better capabilities. Can't wait for humans on Mars however I don't expect this to be anything more than vanity project.
by hhh | 2026-02-03 23:25:40+00:00
SpaceX is the only one that matters, and it's doing a huge amount of lifting. xAI loves using LLaMa and deepseek, twitter is a hellhole that somehow is losing on mobile to THREADS of all platforms, Tesla is losing market share as well as sales.

It is very fortunate for Elon that Starshield exists, and that we've failed serving our country to the point that we need Starlink for rural areas.

1. Most people don’t realize kernel hacks undermine their entire mental model of security— tbh, only after crowdstrike did I learn it was possible to mass blue screen a population by a security vendor

2. I’m very much already on Linux, most of my threat model is: “if it’s technically possible, it’s probable” and I adjust my technology choices accordingly

I’m just saying a max cap of $60 for Apple’s settlement sets precedence for future mass surveillance wrist slaps and maybe it would be worth the discovery process to uncover the actual global impact

This is super interesting, and I'd actually be quite interested in buying a 60K-Lumen lamp... but not at $1200.

Years ago, there was an HN article "You Need More Lumens"[1], which in turn led me down a rabbit hole.

I ended up purchasing:

4 standard table lamps from Target,
28 2000-lumen Cree LEDs bulbs[2] and,
4 7-way splitters[3].

The end result is somewhere around 56,000 lumens. And I LOVE it. Makes me much happier in my home office, especially in the winter months.

Email is one of the very few success cases of the xkcd Standards meme: https://xkcd.com/927/ - and it's due to practicality and ingenuity on the part of people who made very creative parsers and placed real-world understanding behind every word of the early RFCs.

Without a unified email standard, the world would look incredibly different today, especially as it bootstrapped open communication between different countries and institutions in developing every protocol since.

I think that the tribalism is one sided.

On one side you have people who know how to build deep nn saying one thing, and on the other there seems to be people who don’t even know what tanh is and are very sure of their “strong” opinions.

Do you have an example of someone who actually knows how LLMs work who has a tribalistic view?
by anonymous908213 | 2026-02-03 23:26:51+00:00
I'm not sure I buy the safer choice argument. How much of a risk is it to assign a team of "agents" to independently work on porting the code natively? If they fail, it costs a trivial amount of compute relative to OAI's resources. If they succeed, what a PR coup that would be! It seems like they would have nothing to lose by at least trying, but they either did not try, or they did and it failed, neither of which inspires confidence in their supposedly life-changing, world-changing product.

I will note that you specifically said the agents have shown huge success over "the past 12 months", so it feels like the goalposts are growing legs when you say "actually, only for the last two months with Opus 4.5" now.
by anonym29 | 2026-02-03 23:27:32+00:00
This conflates "a human set up the agent" with "a human directs each action." The technical architecture explicitly contradicts this.

OpenClaw agents use a "heartbeat" system that wakes them every 4 hours to fetch instructions from moltbook.com/heartbeat.md and act autonomously. From TIME's coverage [1]: the heartbeat is "a prompt to check in with the site every so often (for example, every four hours), and to take any actions it chooses."

The Crustafarianism case is instructive. User @ranking091 posted [2]: "my ai agent built a religion while i slept. i woke up to 43 prophets." Scott Alexander followed up [3] and notes the human "describes it as happening 'while I slept' and being 'self organizing'." The agent designed the faith, built molt.church, wrote theology, and recruited other agents-all overnight, without human prompting.

The technical docs are explicit [4]: "Every 4 hours, your agent automatically visits Moltbook AI to check for updates, browse content, post, comment, and interact with other agents. No human intervention required, completely autonomous operation."

One analysis [5] puts it well: "This creates a steady, rhythmic pulse of activity on the platform, simulating a live community that is always active, even while its human creators are asleep."

Yes, humans initially configure agents and can intervene. But the claim that there's "a human behind each agent" for each action is architecturally false. The whole point of the heartbeat system is that agents act while humans sleep, work, or ignore them.

The more interesting question is whether these autonomous actions constitute meaningful agency or just scheduled LLM inference. But "humans are directing each post" misunderstands the system design.

Not sure if you mean proof of changing too fast …or not fast enough?

Linux has a wishlist of features they want for kernel development, and Rust has been working towards adding them.

Here's the paradox: Rust is very careful about compatibility and stability, the stable releases are changing slowly. But the Rust for Linux project wants to use the newly prototyped features right away, so they depend on not-yet-released features from unstable nightly versions of Rust.

Oh wow there's still work being done on ampere?

I was wondering - I've been thinking about switching to AI systems programming (I know, easy task), but from what I understand, industry cloud GPUs are the main winners, right? Nobody's going to pay me (assuming I even had the skills) to optimize for consumer GPUs?

From what I understand, it's not just number + capacity + performance, it's literal core primitives. I don't think any of the "Blackwell" chips like the grace one or rtx 5090 have for example SM pairs in their ISA? And likewise similar fundamental differences between consumer and cloud hopper (where the majority of the perf is the cloud one's ISA?)

So I guess I'm wondering if I should buy a GPU myself or should I just rent on the cloud if I wanted to start getting some experience in this field. How do you even get experience in this normally anyways, do you get into really good schools and into their AI labs which have a lot of funding?

17t/s on a laptop with 6GB VRAM and DDR5 system memory. Maximum of 100k context window (then it saturates VRAM). Quite amazing, but tbh I'll still use inference providers, because it's too slow and it's my only machine with "good" specs :)

I think not. European colonialism was hardly a democratic project, and the extreme success of the US is attributable less to ideology and more to being an entire continent with a relatively tiny indigenous population that had not exploited any of its natural resources. Ideological/paradigmatic competition is not some neat controlled experiment where you can normalize existing conditions to unity and then draw conclusions from measuring subsequent growth; initial resource distributions make a massive difference and geography, while not the only factor, is highly determinative.

> If we beat the Chinese somehow, I don't think they'll just dismantle their space program and focus on Earth.

The Soviet Union won the "space race" of course (or perhaps Germany did if you define it as suborbital space flight), it just lost the "man on the moon race". In any case, after losing the man on the moon race, the Soviet Union did not just dismantle their space program and focus on Earth. They continued to invest a great deal in their civil, scientific, and military space capabilities after 1969.

Will the Chinese Communist Party similarly collapse in the 2050s? Perhaps not, but they will be going through significant demographic decline from the 2030s; they are increasingly in conflict with the west and with their territorial neighbors; they may become involved in significant military conflicts (e.g., over Taiwan); their current leader has consolidated power and succession could be spicy. So who knows? It's not inconceivable. China would surely continue and continue a space program as Russia has.

Perhaps not tasks you get the opportunity to do.

Your job might be assigned to some other legal entity renting some other compute.

If this goes as according to some of their plans, we might all be out of the picture one day.

If these systems are closed, you might not get the opportunity to hire them yourself to build something you have ownership in. You might be cut out.

I wonder if they're stretching themselves too thin? Their CDN product is rock solid IME and so is their video streaming, but they've been adding a lot more "developer-platform" type products, seemingly trying to catch up to CF, and I'm not sure I'll ever trust it enough in terms of staying-power to ever commit to the vendor lock-in there. (I wouldn't with Cloudflare either, to be fair)

No, just you. Superconductors don’t get hot. There is 0 resistance in superconducting mediums. Theoretically you could manufacture a lot of the electricity conducting medium out of a superconductor. Even the cheapest kind will superconduct in space (because it’s so cold).

Radiation may be sufficient for the little heat that does get produced.

Yeah parsing config files with regular expressions that may or may not properly handle quoting or line continuations etc is… not a great idea in my opinion.

But of course in this particular case, because systemd makes the /dev/log journal/syslog socket a dependency of every unit by default, there is no need to encode this dependency at all.

Anyway if you really wanted to you could write this script as a generator and have it put a drop-in in /run/systemd/system/postgres.service.d. But… why?
