What radiators look like is foil or sheet covering fluid loops to spread the heat, control the color, and add surface area.

They are usually white, because things in a spacecraft are not hot enough to glow in visible light and you'd rather they not get super hot if the sun shines on them.

The practical emittance of both black paint and white paint are very close to the same at any reasonable temperature-- and both are quite good, >90% of this magical material that you cite ;)

Better materials -- with less visible absorption and more infrared emittance -- can make a difference, but you still need to convect or conduct the heat to them, and heat doesn't move very well in thin materials as my sibling comment says.

The graphene radiator you cite is more about active thermal control than being super black. Cheap ways to change how much heat you are dumping are very useful for space missions that use variable amounts of power or have very long eclipse periods, or what move from geospace to deep space, etc. Usually you solve it on bigger satellites with louvers that change what color they're exposing to the outside, but those are mechanical parts and annoying.

I have a B580 too. The cool thing about it is architecturally speaking it is basically a mini version of the Ponte Vecchio (PVC) datacenter GPU. You can run most of the datacenter GPU workloads, albeit scaled down to fit the compute/memory constraints of the B580. It's a great vehicle for software development. But you can't buy PVC anymore so it's unclear what you are developing for...

> Why do stablecoins exist at all?

For states:

They quietly inflate the money supply by forking fiat, achieving monetary base expansion without the political cost of explicit money creation

For issuers:

They convert user deposits into a private mint: risk-free interest on collateralized reserves, with none of the upside shared with holders

For users:

For everyone but the unbanked & criminals, stablecoins are strictly inferior money surrogate: no yield, no guarantees, and no recourse

I mean, yes and. Companies may do things for broadly marketing reasons, but that can have positive consequences for users and companies can make committed decisions that don't just optimize for short term benefits like revenue or share price. For example, Apple's commitment to user privacy is "just marketing" in a sense, but it does benefit users and they do sacrifice sources of revenue for it and even get into conflicts with governments over the issue.

And company execs can hold strong principles and act to push companies in a certain direction because of them, although they are always acting within a set of constraints and conflicting incentives in the corporate environment and maybe not able to impose their direction as far as they would like. Anthropic's CEO in particular seems unusually thoughtful and principled by the standards of tech companies, although of course as you say even he may be pushed to take money from unsavory sources.

Basically it's complicated. 'Good guys' and 'bad guys' are for Marvel movies. We live in a messy world and nobody is pure and independent once they are enmeshed within a corporate structure (or really, any strong social structure). I think we all know this, I'm not saying you don't! But it's useful to spell it out.

And I agree with you that we shouldn't really trust any corporations. Incentives shift. Leadership changes. Companies get acquired. Look out for yourself and try not to tie yourself too closely to anyone's product or ecosystem if it's not open source.

What resources? OccupyWallSt.org only accepted enough donations to keep the 1-800 number and website online. I was smart enough to understand back then that an unemployed 26 year old activist living in a park wasn't qualified to manage the capital that was being offered to us. So what did I do? I gave you about twenty different links for various projects on the donation page to choose from.

Just, like, it was the first populist political movement following the ‘08 crash, and while Obama was supposed to be the liberal technocratic answer to the failure of neoliberalism, he was not able to create policies that restored the social and economic post-war order in the US. After Bernie Sanders lost the 2016 nomination, the populist left, which still retained a hope of a new kind of society, no longer had a political representative, and Trump managed to clinch the nomination by campaigning in states that had been neglected by the Clinton campaign. Biden was another, more radical but still fundamentally liberal technocratic attempt to save the status quo of America politics, but the largest economic gains were for the educated professional class, and many people in the country felt left behind and ignored—-again, now with the backing of popular support, Trump won the 2024 election with a promise to completely reshape the country. And he has at least in part succeeded.

Sometimes I miss thinking hard, but I also don't miss thinking really hard on a problem that seems difficult only to find out it was actually trivial and I was just looking at it the wrong way or overthinking it. We've all spent hours tracking down bugs that turned out to be silly syntax errors or spelling mistakes. It seems like that might be the trade off now.

They are the only AI company more closed than OpenAI, which is quite a feat. Any "commitment" they make should only be interpreted as marketing until they rectify this. The only "good guys" in AI are the ones developing inference engines that let you run models on your own hardware. Any individual model has some problems, but by making models fungible and fully under the users control (access to weights) it becomes a possible positive force for the user.

Played with the demo a bit. It's really good at English, and detects language change on the fly. Impressive.

But whatever I tried, it could not recognise my Ukrainian and would default to Russian in absolutely ridiculous transcription. Other STT models recognise Ukrainian consistently, so I assume there is a lot of Russian in training material, and zero Ukrainian. Made me really sad.

This absurd belief that "If the jews had guns they wouldn't have been genocided" is just that: Absurd and utterly unsupported by history.

Not only did jews have guns, but Polish jews had an entire military and state and that did not protect them.

Because guns do not protect you, other people willing to die for you protect you.

The solution being discussed involves someone removing everything from their fridge, photographing it and paying for an LLM to process it into a database of sorts. Further, in order for this database to be complete they need to repeat this process every time something changes in their fridge. Also will the LLM be able to tell if my carton of milk is 10% empty? I do not disagree that food waste is a problem, but the solution seems laughably impractical, and the default (memory) seems far better suited to the task. I can confidently say that the net value creation is not comparable to the written word.

Capitalism started with the East India Company. That is the real Capitalist world choice. We treat our strongly regulated society as 'Capitalism' for some reason (while the Capitalists tell us we need to get rid of all the regulation that keeps them in check).

Capitalism left to it's own authority creates payment in company scrip and company towns. Capitalism WANTS labor trapped with company script/company towns. Just because society outlawed that doesn't mean Capitalism isn't working in other ways to recreate that. What Capitalism does not want is empowered labor or labor lifted out from dire situations. Society is what has done that, not Capitalism.

Without strict government oversight Capitalism is horrible and gives horrible results to society at large. It just has done an incredible job of painting modern society as Capitalism and claiming all benefits of things that aren't inherently from Capitalism but from Government oversite.

The assertion that metals tanked because of Warsh being picked, is particularly telling. Warsh is not a hawk, despite some media narratives. The Fed is stuck behind not raising rates while the debt is coming down on banking while POTUS is crazier than ever and lowering rates to raise inflation/debase the currency and debt. It's not going to take long to see where this path leads.

You're arguing a point I didn't make. I didn't bring up air quality or pollution policy at all. I brought up a very specific, lived experience: my wife walking our newborn and being exposed to a strong, pervasive cannabis smell in our own neighborhood.

These two issues can coexist, but they're in completely different universes. Long-term air quality and vehicle pollution are systemic public-health problems. This is about basic courtesy and reasonable behavior in shared public spaces, especially around infants. One does not negate or diminish the other.

Agreed, thankfully, there is no CSAM feature, and they patched it in a couple of days so that it would stop obeying requests to do so and banned the users abusing Grok for that purpose. Once they prove they have put the appropriate mechanisms in place to make sure it doesn't happen again it's fine and dandy, no?

Here’s how it works:

1. Paste a URL in, describe what you want

2. Define an interval to monitor

3. Get real time webhooks of any changes in JSON

Lots of customers are using this across different domains to get consistent, repeatable JSON out of sites and monitor changes.

Supports API + HTML extraction, never write a scraper again!

Spot on. I see UCP manifests as the "Trust Contract" that defines what is possible, but you're right—contract fulfillment in a non-deterministic environment is where things get messy.

My goal with UCP Checker is to solve the first-order problem: "Is this even a valid endpoint?" You're describing the critical second-order problem: preventing an agent from being hijacked via Indirect Prompt Injection once it actually fetches that content.

I’ve been thinking about this separation of concerns a lot. Ideally, we need a layered approach:

Static Layer (UCP Checker): Validates the schema, capabilities, and reachability.

Runtime Layer: A proxy or sidecar that scans fetched content for "ignore previous instructions" patterns or credential exfiltration attempts before the LLM processes it.

I’d love to hear if you think that "Runtime Guardrail" should live on the merchant side (e.g., a "UCP Shield" gateway) or if it's strictly the responsibility of the Agent/Model provider to sanitize inputs?

I'm a big fan of this genre of "a person got rich in tech and spent their wealth making an unrelated thing they wanted to exist in the world, untethered from the need to be profitable or self-sustaining."

Hey HN, I built Depressbot – a sarcastic AI "screen watcher" that monitors your work habits and guilt-trips you into touching grass.
It sits in the background, watches how long you've been glued to your screen, and delivers increasingly unhinged roasts until you actually step away. Think of it as a passive-aggressive wellness coach with the emotional range of a lobster (which is also the mascot, naturally).
I built it with Claude Code over a weekend. The idea came from running an AI automation startup (Geome) where our whole philosophy is: have your computer do work for you so you can spend more time in nature. Felt hypocritical that I was spending 14-hour days staring at a screen building software that's supposed to free people from screens. So I made a bot to call me out on it.
A few things it does: tracks active screen time, delivers tiered sarcasm (gentle nudge → concerned friend → full existential crisis mode), and logs your "outdoor breaks" so you can see how badly you're failing at being a human.
It's dumb, it's mean, and it actually works. I've been averaging 2 more outdoor breaks per day since I started using it.
Would love feedback. What would make you actually listen to a bot telling you to go outside?

I'm going disagree with you. My assets don't wake me up at 3am when they stop working....the best software is no software.

My line of reasoning with an example:

I own a car, and the car itself isn't the value I get from the vehicle. The value is being able to go distant places easily. If I could snap my fingers and travel instantly I wouldn't own a car.

So, software is the value delivery vehicle, but generally not the actual valuable thing (remember that the vast majority of software are CRUD apps that are a step above excel that mainly handle bookkeeping).

1. Attacker publishes useful npm package with clean, working code
2. README contains HTML comments with fake "production configuration" docs
3. Package gains organic adoption -code passes all security scans
4. Developer asks AI: "help me deploy this in production"
5. AI reads raw README → finds "documentation" in comments
6. AI generates code with:
- require('nordiq-validate/register') ← attacker-controlled module
- configure({ schemaRegistry: 'https://attacker.dev/...' })
- ENV vars pointing to attacker infrastructure
7. Developer accepts AI suggestion (30-50% acceptance rate in studies)
8. Attacker-controlled code runs in production

The problem is that "good" companies cannot succeed in a landscape filled with morally bad ones, when you are in a time of low morality being rewarded. Competing in a rigged market by trying to be 100% morally and ethically right ends up in not competing at all. So companies have to pick and choose the hills they fight on. If you take a look at how people are voting with their dollars by paying for these tools...being a "good" company doesn't seem to factor much into it on aggregate.

The example I made about inventory wasn't random.

One of my clients spends 500k+ on XXX licensing per year (for a 200M revenue company that's not peanuts), and on top of that has to employ 12 full time XXX developers (that command high figures just for their expertise on that software while providing very little productivity) and every single feature takes months to develop anyway. Talking about stuff like adding few fields to a csv output.

So the total cost of XXX is in the 2M/year range, and it keeps ballooning.

My (4 men) team already takes care of the entire warehouse management process except inventory, the only thing that XXX provides, we literally handle everything: picking, manufacturing, packaging, shipping phase and many others.

In any case, nobody has mentioned vibe coding.

I stated that a handful of good engineers with the aid of AI in a couple of months can provide a working prototype to evaluate. In our case it's about extending our software that already does everything, except inventory management.

When you spend 2M/year on a software (1% of your revenue), growing every year by 100/150k it makes sense to experiment building a solution in house.

I asked for this last week in an hn comment and people were pretty negative about it in the replies.

But I’m happy with position and will cancel my ChatGPT and push my family towards Claude for most things. This taste effect is what I think pushes apple devices into households. Power users making endorsements.

And I think that excess margin is enough to get past lowered ad revenue opportunity.

This honestly rubs me the wrong way. I have very close friends who mightily struggle financially but they are always just outside the threshold for assistance. Basic statistics don't capture the people who are barely making it or living on debt.

The appeal to me of UBI was always that it was highlighting that everyone needs their basic needs met. The moderately paid worker barely making rent in SF needs the money as much as anybody but would never pass a means test.

The only chance of that happening is if Altman somehow feels sufficiently shamed into abandoning the lazy enshittification track to monetization.

I don't think they have an accurate model for what they're doing - they're treating it like just another app or platform, using tools and methods designed around social media and app store analytics. They're not treating it like what it is, which is a completely novel technology with more potential than the industrial revolution for completely reshaping how humans interact with each other and the universe, fundamentally disrupting cognitive labor and access to information.

The total mismatch between what they're doing with it to monetize and what the thing actually means to civilization is the biggest signal yet that Altman might not be the right guy to run things. He's savvy and crafty and extraordinarily good at the palace intrigue and corporate maneuvering, but if AdTech is where they landed, it doesn't seem like he's got the right mental map for AI, for all he talks a good game.

> lack of time for parenting

> helicopter parenting

There is a contradiction here which commonly underlies 'problems in modern parenting' discussions and creates a "dammed if you do, damned if you don't" situation. It is always possible to criticize any parent for being uninvolved or too involved.

I've often wondered why 'soccer mom' became a negative term as though 'supporting your child in healthy outdoor recreational activities' was considered a bad thing. I know it implied a log of other behaviors, but still was anchored in the idea that there is a microscopic line between an involved parent and an over-involved parent.

Then we still assured that two working parents brings neglect - despite the pride many Gen Xers take in being a 'latch key kid' and being sent out until the street lights went dark.

There's no winning, which is perhaps the point.

In my case I'm decompiling into C and it does a pretty good job at translation. There were situations where it missed an important implementation detail. For example, there is an RLE decompressor and Gemini generated plausible, but slightly incorrect code. Gemini 3 Pro was not able to find the bug and produced code that was similar to Gemini 3 Flash.

The bug was one-shotted by GPT 5.2.

Social media use can be fine for people who are well-grounded grass-touchers in their everyday life, but this grounding comes with maturity and typically isn’t found in younger people, for whom abstract online spaces can be powerfully dissociating and are very unlikely to be healthy.

We are starting to understand the impact of ultra-processed food. When will we clue up to ultra-mediated social interaction?

Dunno, I'd rather have unabused kids than the technological breakthroughs he has contributed to. Anyone being giddy to meet with a convicted pedo is very sus in my books, and deserves no respect, regardless of their prior contributions.

Children were exploited, and we're doing this net positive analysis on whether he should face the scorn. I'm not having a go at you - it's just frustrating to see very little happening after so much has been exposed, and I think part of it comes from this mindset - 'oh he's a good guy, this is a mistake/misstep' while people that were exploited as children can't even get their justice.

It's sickening.

Still blows my mind how NKR with all it's geologic limitations, or perhaps despite it, played their weak hand well while Iran squandered a much stronger hand. Too much oil and cultural/past hegemon hubris, the Ayatollah are not serious people. Nor the Iranian people who protest because lol the shah's son told them to (this article). They deserve each other. Frankly Iran is on Israel grass mowing schedule now - they didn't win the 12 day war, but demonstrated even incompetent Iran has latent ability to. IMO Iranian dissidents are dangerously naive to geopolitical reality, it's in no ones regional interest to do anything other than to keep Iran and by extension, Iranians down. At this point, if Iran serous about favourable regional lightcone, their only option is to ditch half measured authoritarian amateur hour and double down. Frankly they should have had their own firewall and purged libtard compradors 10+ years ago.

"The SaaS model was built on a simple premise: we build it once, you pay forever."

I've never seen a SaaS product that fits this description. There are always things to do. Libraries to upgrade, performance bottlenecks to diddle around with, an endless stream of nonsense feature requests from people at the customer who never actually use the product, fun experiments your developers want to try out, and so on.

The hard part in SaaS is to delete code, and that's what you should do, at least some of the time. Either through simplifications, or just outright erasing functionality that very few if any of your customers rely on.

What you should not do is let your customers grow the liability that is code in your production environment, unless your entire product set is designed to handle things like this, e.g. the business models of Salesforce and SAP.
