I genuinely did not expect to see a robot handling clothing like this within the next ten years at least. Insanely impressive

I do find it interesting that they state that each task is done with a fine tuned model. I wonder if that’s a limitation of the current data set their foundation model is trained on (which is what I think they’re suggesting in the post) or if it reflects something more fundamental about robotics tasks. It does remind me of a few years ago in LLMs when fine tuning was more prevalent. I don’t follow LLM training methodology closely but my impression was that the bulk of recent improvements have come from better RL post training and inference time reasoning.

Obviously they’re pursuing RL and I’m not sure spending more tokens at inference would even help for fine manipulation like this, notwithstanding the latency problems with that.

So, maybe the need for fine tuning goes away with a better foundation model like they’re suggesting? I hope this doesn’t point towards more fundamental limitations on robotics learning with the current VLA foundation model architectures

> China was playing industrial catch up. They didn't have to (for example) reinvent semiconductors from first principles. They will surely support some form of IP law once they have been firmly established at the cutting edge for a while.

That argument was in vogue about 20 years ago, but it fell out of favor when China passed us on the most important technologies without slowing down.

It is funny that some people are still carrying the torch for it after it's been so clearly disproven.

Nah. 99.9% of the people who wanted the addition of DryStructs to a codebase I worked on wanted it because they'd been bit, repeatedly, by someone sending one kind of object into a function rather than what the function accepted and it just not getting caught.

A robust type system allows you to make "compiler errors" out of runtime errors. One of these takes *way more tests to catch* than the other. I'll let you guess which.

I believe that’s the main reason why you dislike AI, but I believe if you asked everyone who hated AI many would come up with different main reasons why they dislike it.
I doubt that solution would work very well, even though it’s well intentioned. It’s too easy to work around it, especially with text. But at least it’s direct, as really my main point is we need to sidestep the emotional feelings we have about AI and actually present cold hard legal or moral arguments where they exist with specific changes requested or be dismissed as just hating it emotionally.

Meta campaigns often underperform not because of creative or targeting, but because budget is fragmented across too many ad sets, starving the algorithm of signal.

The underlying constraint is simple:

Meta requires ~50 optimization events per week per ad set* to exit the learning phase and stabilize delivery.

This calculator exists to make that constraint explicit — and to translate it into practical budgeting and consolidation decisions.

Every time I think about EVs, I become filled with dread thinking about what will happen if an area loses power for an extended period of time. I used to live in an area that had transformers blow from rain showers.

At least you could hook up a generator to pump gas at a gas station.

:/ Life's about trade offs.

Edit: Whoops.. Im not against EVs to be clear. But from a safety POV, having two different energy sources is safer than having one. Im not sure if you'll understand this if you haven't lived in a very snowy state.

I'm not sure that tracks with my experience, plenty of 20-30 year old cars still running around. The people upgrading every few years do it for financial or image reasons rather than because the car stopped working.

Warranty anxiety is probably a big factor too, which could be legislated. Imagine how reliable cars would be if a 30 year warranty on drivetrain components was mandatory.
Neuro‑IDE: A Visual Surgical Environment for Kernel Analysis
by neuro-os | 2025-12-27 03:25:58+00:00
I’m releasing Neuro‑IDE, a visual low‑level laboratory for interacting with kernel images in real time.
It’s not an editor — it’s a surgical cockpit for OS‑Dev, reverse engineering and memory analysis.

What it does:

Real‑time memory scanning

Leak detection and defragmentation

Integrated Hex Editor and Disassembler

Multi‑pane “Antigravity” UI (like a tiled cockpit)

Kernel telemetry and system biometrics

A narrative debugging module (“Kernel Storyteller”)

What it’s for:

OS developers

Low‑level enthusiasts

Cybersecurity students

Anyone who wants to see how a kernel behaves internally

It’s fully open‑source, has zero external dependencies, and works with any kernel image.

GitHub: https://github.com/cyberenigma-lgtm/Neuro-IDE-Universal-Kernel-Cortex

Happy to answer questions or share technical details.

> This is interesting in that I wouldn't expect that the typical resolution involves a particularly large quantity of TOML.

I don't know the details of Python's resolution algorithm, but for Cargo (which is where epage is coming from) a lockfile (which is encoded in TOML) can be somewhat large-ish, maybe pushing 100 kilobytes (to the point where I'm curious if epage has benchmarked to see if lockfile parsing is noticeable in the flamegraph).

I slowly climbed up the ranks of the "Go" ladder over the course of playing 1-2 games a week for a couple of years. "Play a lot" doesn't require "play a lot TODAY". There's a ton of games that have stable, long-term communities where you can reasonably expect that game to be around in 5-10 years.

What about the interior? There’s no one thing you can point to in a car interior and say “that’s no good after X years” but we’ve all seen the interior of old cars.
The batteries in modern EVs will last the lifetime of the vehicle [0] but what factor(s) determine that lifetime are unknown I think.

Right now is an incredible time for miners. Diesel is at multi-year lows, bulk ocean freight is relatively inexpensive, and almost the entire metals index is soaring. Through happenstance, I know someone at Bridgestone's mine truck tire division, and they are having one of their best years ever. Wonder if we will see $1m salaries for explosive engineers like we did in ~2010

I recall idly looking through the manual of our Bosch dishwasher when it was delivered and seeing that they offered to share GPL'ed source code from the machine's embedded guts. I thought to myself, "that's kind of interesting, I'll take them up on that". So I emailed the address they provided for this purpose. I got an auto email back saying, effectively, "No. You're not an authorised person, we don't recognise your email address, we don't know who you are, we're not going to talk to you."

Oh well. Big Corp doing what Big Corps do. Paying lip service to legal requirements, but reluctantly and with barriers that would no doubt take a lot of time and money to even try and break down.

Back in the 1960s, when I was a tween- or teen-ager, I read every copy of Analog Science Fiction/ Science Fact I could put my hands on. You can now read lots of those stories on-line (like at https://www.freesfonline.net/Magazines2.html). Some of them have stood the test of time, but some are really really bad. John Campbell, the editor of Analog back then, was racist, and also convinced that smoking tobacco was a Good Thing. Many of the stories were written (by others) to convey those ideas; it's almost unusual for lead characters not to light up a cigarette.

It will be interesting to see how much of today's scifi holds up half a century from now---not because the science is wrong, but because the moral qualities will be judged outlandish.

That sounds like the extreme version of "but I need a fuel car because I want to drive it to France once a year for holiday". Driving something around all year for a once-a-year event is silly, but this is just insane. In a good life, you don't need this fallback from grid power even once in your lifetime!

At least, not beyond the inconvenience that is having to stay at home like 1 unplanned day per several decades. That's still three and three quarters of a nine of uptime even if you'd get the recent Iberian peninsula event every 10 years, and assumes you emptied the battery coincidentally the day before the outage. If you're not an EMT or power plant technician, you're doing more harm than good by being the person who can drive to work during a power outage and find that you're the only one there and nothing works anyway

Unpopular idea: the personal automobile segment will shrink so rapidly when autonomous, ubiquitous, low-cost EV robotaxis reach widespread proliferation, that many of the existing automotive manufacturers today will become increasingly commercially non-viable and wind down operations anyway, only further accelerating a trend that has already begun due to the rampant, multifaceted rise in total vehicle ownership costs far above CPI inflation.

Environmentalists should be happy about this either way. A fleet of high utilization autonomous vehicles will increase utilization rates of each automobile that is still on the road substantially, serving more people with fewer raw materials. Not to mention that as of right now, all of the leading contenders for commercially viable robotaxi fleets are on EV platforms anyway.

It's not that, by and large, over a longer time horizon, new gasoline cars are going to replace these EVs disappearing from the consumer-owned automobile segment so much as EV robotaxis will be gradually replacing almost all consumer-owned vehicles. Enthusiasts will still have their track toys, but as an economic mode of transportation, the personally owned automobile is going the way of the horse and buggy.
Show HN: Why delegation beats memory in AI Agents
by akshay326 | 2025-12-27 03:30:31+00:00
We've spent the last 6 months building Seer, an agent engine for enterprise workflows. We’re launching on NYE, but honestly, we’re still in the trenches.

While scanning the space, I keep seeing devs (us included, initially) get obsessed with complex "memory" layers and graph-based reflection. In practice, we found they mostly lead to context poisoning and high latency.

We pivoted to a "Barbell Strategy": Crisp, lean inter-agent instructions paired with massive, localized "artifact" context for sub-agents that are immediately killed after the task.

I’m curious—for those of you building agents in production:

Have you found a way to make "long-term memory" actually reliable, or are you also moving toward ephemeral, specialized agents?

What’s the "boring" plumbing problem (Auth, state rollback, etc.) that took you way longer to solve than the actual AI logic?

> I would trust the people that hack on these systems to be even more motivated than the manufacturers to make sure they don't fuck up

I would think it's the opposite. People that hack on this only risk their own life. Companies risk many people's lives and will get sued. Of course the person doing the hacking doesn't want to die but they're also willing to take the risk.

Most ruby code isn't written like that - it's written like most static languages, where objects conform to interfaces / traits / type classes / pick your poison. The community is shifting towards explicitly specifying and statically checking types now. rbs and sorbet are a testament to this.

I wouldn't say it's really a beauty of the language, it may have been the original design intent but time has shown what's actually maintainable.
by satvikpendem | 2025-12-27 03:32:50+00:00
A bunch of companies started a decade or two ago and became very successful using the dynamic language du jour back then, and now they're facing issues with said dynamism, so they introduce types to fix those issues, see Meta with Hack over PHP and Stripe with Sorbet over Ruby. The point is not for new users, it's for existing users to improve their development environments.

Have you considered that the people in the 1990s were mostly correct, and it's you that has been corrupted by modern marketing influences and external pressures?

There's no shortage of "Chicken Little" technologies that look great on-paper and fail catastrophically in real life. Tripropellant rockets, cryptocurrencies, DAOs, flying cars, the list never ends. There's nothing that stops AI from being similarly disappointing besides scale and expectation (both of which are currently unlimited).

I knew what I was doing. I don't know if I'd describe it as selfish so much as deliberately provocative.

I agree with Rob Pike that sending emails like that from unreviewed AI systems is extremely rude.

I don't agree that the entire generative AI ecosystem deserves all of those fuck yous.

So I hit back in a very subtle way by demonstrating a little-known but extremely effective application of generative AI - for digital forensics. I made sure anyone reading could follow along and see exactly what I did.

I think this post may be something of a Rorschach test. If you have strong negative feelings about generative AI you're likely to find what I did offensive. If you have favorable feelings towards generative AI you're more likely to appreciate my subtle dig.

So yes, it was a bit of a dick move. In the overall scheme of bad things humans do I don't feel like it's pretty far over the "this is bad" line.

Passing an &uninit to a combinator seems like it would be strange.

But if you told me that some strongly typed language wanted to have coroutines and futures, that coroutine bodies would not execute at all until first polled, and that it was okay to move the thing you have before polling not the thing you had after polling, and I hadn’t seen Rust, I would maybe suggest:

1. Creating a Future (i.e. logically calling an async function) would return an object that is, conceptually, a NotYetPolledFuture. That object is movable or relocatable or whatever you call it (or it’s movable if and only if the parameters you passed are).

2. Later you exchange that object for a LiveFuture, which cannot be moved.

Rust has two limitations that would make this awkward:

- Rust doesn’t actually have immovable objects per se.

- The exchange is spelled fn exchange(val: Type1) -> Type2, which doesn’t work if Type2 is immovable.

But the &uninit/&own proposal in the OP is actually secretly a complex scheme using lifetimes to somewhat awkwardly do an in-place exchange from an uninitialized type to an initialized and owned type. Maybe that proposal could be extended a little bit to allow type exchanges. (Maybe it already does, sort of? You could pass an &uninit Future and a FutureToken and get out an &own Future, with the caveat that this would force the fields in the token to be moved unless the optimizer did something truly heroic.)

If anyone deserves this, it’s Rob Pike. He was instrumental in inflicting Go on the world. He could have studied programming languages and done something to improve the state of the art and help communicate good practices to a wider audience. Instead he perpetuated 1970s thinking about programming with no knowledge or understanding of what we’ve discovered in the half-century since then.

> The music indsutry is well aware of a phenomenon of a "one-hit wonder".

He made two hit games, Witness was released 7.5 years later.

> Within a week of release, Blow stated that sales of The Witness had nearly outpaced what Braid had done during its first year of release.

> The Witness is widely regarded as one of the best games of the 2010s. The game appeared on 'Best of the decade' features from IGN,[103] Polygon,[104] NME,[105] CNET,[106] and National Post.[107] Edge considered the game the 22nd-best game of all time in 2017

Calling him "one-hit wonder" simply has no basis in reality.
He's at minimum a two-hit wonder.

> it was most likely not as groundbreaking as Braid, considering that he chose Braid instead of The Witness for a remaster.

Now you're making shit up on the spot to make an argument.
Think for a second will you, how exactly would he remaster Witness? Braid Anniversary Edition was announced on 2020,
at which point Witness would merely have been ~4 year old game.

Braid was also made for a 720p console, the Xbox360 Xbox Live Arcade service, so remake atleast makes some sense.

> The question I'm interested in is: why would anyone listen to what the man _says_ if his own preaching makes him lose money?

What exactly is he _preaching_? Not what you have cooked up in your mind, but actually _preaching_?

Why would anyone pay attention to the man who has made TWO hit games in a row, and a third one in his own programming language (that has inspired countless other programming languages like Zig and Odin), yes, why indeed people would listen to an exceptional guy who has repeatedly demonstrated competency and delivered results, whilst always putting it all on the line?

Can you make atleast one hit, not two, just one? Or anything of note?

No you can't, you can do nothing, that's why you don't have the "luxuries" and people don't listen to you, but pay attention to him. You might not like it, but it is what it is.

And you like to comfort yourself with the thought that you don't have some sort of unearned "luxuries", because otherwise you would do great things.

But the reality is that he's exceptional and you're not.

Yes indeed. That said nix typically throws away the .git dir so it would require some work to adapt a solution to nix that operates at the git repo level.

The ideal for nix would be “I have all content at commit X and need the deltas for content at commit Y” and i suspect nix would be fairly unique in being able to benefit from that. To the point that it might actually make sense to just implement the fact git repo syncs and have a local client serving those tarballs to the nix daemon.

my area lost power for about 3 days last week and I ran all of my house's critical systems from my EV. it was great - silent, unlike the old generator, and not counting the sunk cost of the car, extremely cheap. Cost maybe $5 in electricity to keep the furnace, refrigerator/freezer, and internet on for 3 days, contrasted with probably $50 in gasoline for a similar amount of time.

If the outage had been longer, I could have made a half-hour trip to an area that had working EV fast chargers and come back with another 5-6 days of power for the house.

Again, why haven't they done it yet? It's because you cannot lock down a development platform. Yes, they could do it but it doesn't make any sense. You haven't articulated why they would do it only that they could.

Marketing looks nice, but why do they make it so hard to build trust? If it's a software focused on developers it's really important to establish trust.

The page on https://devblog.qnx.com/about/ does not show what kind of company it is, who is behind it, and where they are located. Should I expect backdoors? Is it an elaborate front by north korea? Who will be able to remotely execute code on this operating system?

It's nearly 2026 and fake job applications by nation-state threat actors are common. If a new open source project with shiny marketing pops up it would really help if there is some proof that the org behind it consists of humans living in democratic countries.

Edit: The about page links to https://qnx.software/en which only shows a black screen for me.

You are not allowed to decide how everyone else should live. But just for the sake of argument, take a trip to Montana and get back to me on how well universal EVs would work in much of the US. They're fine for urban and suburban areas. They aren't so great for agricultural work, and certainly not great for people who live in places you probably haven't visited. I don't even think EVs are a solution for people in Nebraska, let alone places where the weather gets really extreme.

> I suspect you think more effort went into my comment than actually did. I spent less than 60 seconds on: clicking two or three buttons, typing out the names I saw from the other window, then scrolling down and seeing the 501(c)3.

This is a bit frustrating of a response to get. No, I don't believe you spent a lot of time on this. I wasn't imaging you spending hours or even minutes tracking these guys down. But I also don't think it's relevant.

I don't think you'd find it relevant if the Sage researchers said "I didn't spend any effort on this. I only did this because I wanted to make the point that AIs have enough capability to navigate the web and email people. I could have made the point abstractly, but abstract arguments are harder to follow. There was no other intention than what I put in the prompt." It's hence frustrating to see you use essentially the same thing as a shield.

Look, I'm not here to crucify you for this. I don't think you're a bad person. And this isn't even that bad in the grand scheme of things. It's just that naming and shaming specific people feels like an overreaction to thoughtless, machine-generated thank you emails.
