I have read this same comment so many times in various forms. I know many of them are shill accounts/bots, but many are real. I think there are a few things at play that make people feel this way. Even if you're in a CRUD shop with low standards for reliability/scale/performance/efficiency, a person who isn't an experienced engineer could not make the LLM do your job. LLMs have a perfect combination of traits that cause people to overestimate their utility. The biggest one I think is that their utility is super front-loaded.

If a task before would take you ten hours to think through the thing, translate that into an implementation approach, implement it, and test it, and at the end of the ten hours you're 100% there and you've got a good implementation which you understand and can explain to colleagues in detail later if needed. Your code was written by a human expert with intention, and you reviewed it as you wrote it and as you planned the work out.

With an LLM, you spend the same amount of time figuring out what you're going to do, plus more time writing detailed prompts and making the requisite files and context available for the LLM, then you press a button and tada, five minutes later you have a whole bunch of code. And it sorta seems to work. This gives you a big burst of dopamine due to the randomness of the result. So now, with your dopamine levels high and your work seemingly basically done, your brain registers that work as having been done in those five minutes.

But you now (if you're doing work people are willing to pay you for), you probably have to actually verify that it didn't break things or cause huge security holes, and clean up the redundant code and other exceedingly verbose garbage it generated. This is not the same process as verifying your own code. First, LLM output is meant to look as correct as possible, and it will do some REALLY incorrect things that no sane person would do that are not easy to spot in the same way you'd spot them if it were human-written. You also don't really know what all of this shit is - it almost always has a ton of redundant code, or just exceedingly verbose nonsense that ends up being technical debt and more tokens in the context for the next session. So now you have to carefully review it. You have to test things you wouldn't have had to test, with much more care, and you have to look for things that are hard to spot, like redundant code or regressions with other features it shouldn't have touched. And you have to actually make sure it did what you told it to, because sometimes it says it did, and it just didn't. This is a whole process. You're far from done here, and this (to me at least) can only be done by a professional. It's not hard - it's tedious and boring, but it does require your learned expertise.

We're talking about symmetric ciphers and you're talking about password cracking software.

Triple-DES has 168 bit keys. Even if you use a meet-in-the-middle attack, your attack cost has an exponent of 112 (with an associated memory cost with an exponent of 88).

That's not practically exploitable today.

If you think I'm wrong, here's a single block message encrypted with 3DES, then hex-encoded. Have fun:

But really, the bigger problem is Sweet32.

No, basically, the requests are processed in batches, together, and the order they're listed in matters for the results, as the grid (tiles) that the GPU is ultimately processing, are different depending on what order they entered at.

So if you want batching + determinism, you need the same batch with the same order which obviously don't work when there are N+1 clients instead of just one.

MC6809 was actually launched in 1979, like MC68000, about one year after the launch of 8086 in 1978 by Intel.

What Motorola did in 1978 was to publish some articles in the specialized magazines, announcing MC6809 as the future better replacement for their existing MC6800 derivatives. This is the same like Intel describing during last year how great will be their Panther Lake CPU, but Panther Lake has really been launched only a couple of days ago.

> You still gotta understand what you're doing.

Of course, but how do you begin to understand the "stochastic parrot"?

Yesterday I used LLMs all day long and everything worked perfectly. Productivity was great and I was happy. I was ready to embrace the future.

Now, today, no matter what I try, everything LLMs have produced has been a complete dumpster fire and waste of my time. Not even Opus will follow basic instructions. My day is practically over now and I haven't accomplished anything other than pointlessly fighting LLMs. Yesterday's productivity gains are now gone, I'm frustrated, exhausted, and wonder why I didn't just do it myself.

This is a recurring theme for me. Every time I think I've finally cracked the code, next time it is like I'm back using an LLM for the first time in my life. What is the formal approach that finds consistency?

Ah! Now I understand.

I was stepping out with my wife for a day out and had read your reply very cursorily. That reading had left me quite puzzled -- "I would have done exponentially weighted moving average (EWMA) over time for trails. Why is \phi important here in any form. Is \phi the weight of the EWMA ?".

Now I get it, decrementing the pixels were quite peripheral to the main story.

The main story is that of finding a scan sequence that (a) cycles through a set of points without repetition and (b) without obvious patterns discernible to the eye.

In this, the use \phi is indeed neat. I don't think it would have occurred to me. I would have gone with some shift register sequence with cycle length 1024 * 1024 or a space filling curve on such a grid.

This becomes even more interesting if you include the desiderata that the minimum distance between any two temporally adjacent pixels must not be small (to avoid temporal hot spots).

Finding MiniMax, min over temporal adjacency, max over all 1024* 1024! sequences, might be intractable.

Another interesting formulation could be, that for any fixed kxk sized disc that could be drawn on the grid, the temporal interval between any two "revisit" events need to be independent of the disk's position on the grid.

I think this is the road to small discrepancy sequences of quasi Monte Carlo.

EVs are a solved problem, but as amelius notes the real tech is the battery. Tesla + Panasonic has a built in advantage in terms of battery manufacturing. Tesla has a massive amount of capital, if they put it into reducing and scaling manufacturing of vehicles and batteries, I think they could probably win. Now maybe Telsa has looked at the numbers and decided they can't win and are choosing to pivot rather than die a slow death.

I don't think that is what is happening here. Instead, Tesla is continuing the strategy that brought them to this disaster of going all in on driverless. That isn't a bad strategy, but if they get the timing wrong a third time, they destroy the company and they have gotten the timing wrong on this twice already. This strategy has two downsides:

1. AI has no real moat and Tesla has largely pursued commodity sensors, meaning that other than EVs+battery tech (which Tesla appears abandoning), robotaxis have no hardware or software moat.

2. They could use network effects to win, in which case their competitors are not other car companies but Uber and Lyft. Uber has been pursuing the same long term strategy at Tesla.

Now by itself, going all in robotaxi, is risky but could work if they time it right. Tesla isn't going all in on robotaxi since they are splitting the effort between robotaxi and Optimus robots.

It is likely that the experience Tesla gets with Optimus robots will help other robotics companies, but unlike robotaxis where the timing might (but probably won't work), the timing is clearly isn't right for Optimus.

It seems like the motivation here is that Musk is aligning Tesla to a narrative that justify the absurd stock price, even if that narrative isn't reality.

> "Over there" is one of those countries where hundreds of people register their adress with the government at the house of an unsuspecting widow?

In e.g. Germany that requires a signed statement from the landlord, and the ability to receive mail at that address. If you can't receive mail at your own address, it'd be noticed and reported within at most 5 years. I actually believe it'd be the national health insurance that'd be the first to notice & report you missing, as having health insurance is mandatory (even if you continue paying them, they'd notice it once they can't send you a replacement card).

I live near a school zone in LA and most drivers do not obey school zone speed limits.

You will get honked at by aggro drivers if you slow down to the school zone speed limit of 25mph. Most cars go 40ish.

And ofc a decent chunk of those drivers are on tiktok, tinder, Instagram, etc

Interesting reply thanks. I would say though, If I were programmed or a program or whatever you name it... I would realize the under statement:

If One can´t be happy with what One have now, One will never-ever be in any circumstances.

This is not your case certainly but is connected with the autopilot (meaning we don´t get to choose.

Cool to see this on HN today.

I'm currently using RetroArch in the browser along with the original Sony devkit and a custom hot-reload C dev server to develop a PS1 game engine. I started with EmulatorJS but ran into issues with its prebuilt cores while trying to get audio streaming working, and decided to just work with libretro directly.

It's been a blast. I didn't know much about developing on the PS1 and it's been fun playing code golf and trying to squeeze a more modern engine out of its tiny 2MB RAM and 33.8MHz CPU.

You have to understand the people in the article are execs from the chip EDA (Electronic Design Automation) industry. It's full of dinosaurs who have resisted innovation for the past 30 years. Of course they're going to be blowing hot air about how they're "embracing AI". It's a threat to their business model.

I'm a little biased though since I work in chip design and I maintain an open source EDA project.

I agree with their take for the most part, but it's really nothing insightful or different than what people have been saying for a while now.

> Will people really be willing to pay thousands to tens of thousands for a home robot with significant limitations?

The answer to that is no, probably for the foreseeable future. The robot demos we have no can't even fold laundry or put dishes away without being teleoperated. Both extremely basic tasks that any household robot would be required to do, along with other messy jobs that put it at risk as you said: taking out the trash, feeding the pets, cleaning up messes, preparing or cooking food, etc.

The price it would have to cost with current tech would be astronomically more than just hiring a human, and they would almost certainly come with an expensive subscription as well, whereas I can hire a human to come in and clean my home weekly for about $200/month.

The numeric display is localized for the user who got the screen capture. That's how numbers are formatted in India: https://en.wikipedia.org/wiki/Indian_numbering_system . When I check it as a Canadian, the numbers have the usual commas for North American cultures.

It comes across that the sole purpose of this submission is to try to ridicule Musk for putting forward trivially buggy software, hence the quotation marks around the supposedly-incorrectly formatted numbers in the title. Even if that checked out, it would not make for an good submission.

On the off chance that the submission is actually intended to celebrate milestones for Grokipedia (why put quotation marks around numbers, and why not format them as you normally would instead of as they were localized for someone else in a screenshot?), that still isn't particularly interesting.

(Edit: a survey of OP's relatively new account suggests a singular focus on anti-AI stories.)

Whoa, whoa, whoa. That's just one angle. Please don't bin that as the only use case for "world models"!

First of all, there are a variety of different types of world models. Simulation, video, static asset, etc. It's a loaded term, just as the use cases are widespread.

There are world models you can play in your browser inferred entirely by your CPU:

https://madebyoll.in/posts/game_emulation_via_dnn/ (my favorite, from 2022!)

https://madebyoll.in/posts/world_emulation_via_dnn/ (updated, in 3D)

There are static asset generating world models, like WorldLabs' Marble. These are useful for video games, previz, and filmmaking.

https://marble.worldlabs.ai/

I wrote open source software to leverage marble for filmmaking (I'm a filmmaker, and this tech is extremely useful for scene consistency):

https://www.youtube.com/watch?v=wJCJYdGdpHg

https://github.com/storytold/artcraft

There are playable video-oriented models, many of which are open source and will run on your 3080 and above:

https://diamond-wm.github.io/

https://github.com/Robbyant/lingbot-world

There are things termed "world models" that really shouldn't be:

https://github.com/Tencent-Hunyuan/HunyuanWorld-1.0

There are robotics training oriented world models:

Genie is not strictly robotics-oriented.

I remember being called out by name in an Archimedes Plutonium rant around 1993. I also had a post referenced in the comp.lang.c FAQ for a few years. That's the closest I've come to celebrity. The internet before the web brings back memories.

Brew _is_ a linux package manager.

There is also conda/mamba/pixi/etc. (anything in the conda-forge ecosystem) that can be used without root. Then there are Guix and nix, which (mostly) require to be set up by someone with root privileges, but which then allow unprivileged users to install packages for themselves. I think I have even used emerge rootless-ly at some point a few years ago.

BYD uses slave labor.

"In the dormitories of the Jinjiang Group, the company hired by BYD to carry out the work, there were no mattresses on the beds, and the few toilets served hundreds of workers in extremely unhygienic conditions. The workers also had food stored without refrigeration.

The Brazilian Labor Prosecutor's Office (MTP) also accused the companies of withholding the workers' passports and keeping 60% of their wages; the remaining 40% would be paid in Chinese currency."

https://en.wikipedia.org/wiki/BYD_Brazil_working_conditions_...

It's hard for any company to compete with that (I hope they don't).

Yeah. I get charging for hosting an app in your store, that requires work to build the ecosystem and security and stuff. But you have to draw the line on a platform and ecosystem and vetting that someone else has done. What did apple do to build kindles library of books? What did apple do to attract creators that patreon's users would like to support? Nothing. They should get 30% for installing paid apps that they are vetting and hosting, but nothing for things third parties are hosting and vetting

If you have contradicting data I'd be glad to see it

>It's likely that a fully-attentive human driver would have done worse.

Is based off the source I gave in my comment, the peer-reviewed model

> a huge portion of human drivers

Is based on my experience and bits of data like 30% of fatal accidents involving alcohol

Like I said, if you have better data I'm glad to see it

Their revenue is flat for last 4 years. They have established their status outside top 10 manufacturers and losing EV market share to Chinese and Europeans.

Car revenue: -11%
operating margin: 3.86%
Free cash flow -30%

Tesla PE > 280 is magic. Now they are "pivoting" to Cybercab, humanoid robots and investing billions into xAI. Jumping from hype-trend to next without any problem is impressive. Fair valuation always in the future.

Recent advances in reinforcement learning for code generation have made robust environments essential to prevent reward hacking. As LLMs increasingly serve as evaluators in code-based RL, their ability to detect reward hacking remains understudied. In this paper, we propose a novel taxonomy of reward exploits spanning across 54 categories and introduce TRACE (Testing Reward Anomalies in Code Environments), a synthetically curated and human-verified benchmark containing 517 testing trajectories. Unlike prior work that evaluates reward hack detection in isolated classification scenarios, we contrast these evaluations with a more realistic, contrastive anomaly detection setup on TRACE. Our experiments reveal that models capture reward hacks more effectively in contrastive settings than in isolated classification settings, with GPT-5.2 with highest reasoning mode achieving the best detection rate at 63%, up from 45% in isolated settings on TRACE. Building on this insight, we demonstrate that state-of-the-art models struggle significantly more with semantically contextualized reward hacks compared to syntactically contextualized ones. We further conduct qualitative analyses of model behaviors, as well as ablation studies showing that the ratio of benign to hacked trajectories and analysis cluster sizes substantially impact detection performance. We release the benchmark and evaluation harness to enable the community to expand TRACE and evaluate their models.

Maybe you can scale to have one operator operate ten or a hundred household robots at a time.

An autonomous robot that has 99% reliability, getting stuck once an hour, is useless to me. A semi-autonomous robot that gets stuck once an hour but can be rescued by the remote operator is tempting.

Expect security and privacy in the marketing for these things, too, but I don't think that's a real differentiator. Rich and middle class people alike are currently OK with letting barely-vetted strangers in their houses for cleaning the world over.

I think this might be very misleading. I own (in Europe) my 3rd VW.

The reality is, that this check is done in the VW car service, and they do a pre-check. Then they call me on the phone and tell me what they need to fix and how much it will be. I always tell them OK, and they just fix everything before the real check is done. And this is exactly how it always works for all the people I know.

Also, as far as I know, Tesla owners just take the car to a "random" check point and are probably surprised why it didn't pass.

> skiing enthusiast banned by court order in 1999 from posting on the Usenet discussion group "rec.skiing.alpine", after engaging in a flame war with other online posters. The heated exchanges lasted for months, eventually escalating into death threats, until a police detective from Seattle posted a request for all involved to calm down.

One of the things Jim Farley, Ford CEO, brought up was they have a lot of 3rd party suppliers, and changes take a long time to implement. So a firmware update may require change notifications and responses from dozens of suppliers for something like door locks. This was in response to why Ford couldn't do firmware as fast or as often as Tesla. Vertically integrated means you have 1 big ship to turn around. Modern JIT manufacturing means your ship is built of 100s of cards and each one needs to be turned.

The lack of new models from updates I believe comes from the fact the CEO is busy elsewhere and the board is reluctant to address that. They have made the P/E so high that they can only continue to function in one direction, do just enough to bring in more outside investment.

Ideally all cloud applications hostable on any platform would just provide the following services to clients:

A. rendezvous services so clients can connect to one another,

B. storage/retrieval of encrypted data where the host does not have the key to decrypt,

C. transport of encrypted data which cannot be known by the host due to B above.

> How can you trust him to have redundant networks

You can't, so abstract that away at the application layer. Make it not dependent on a single host or network.

I don't think it makes sense to lump some drivers better than waymo and worse than waymo. A human brain automatically thinks of all the scenarios, where Waymo has pre-programmed ones (and some NN based ones). So it's scenarios by scenario.

Consider this scenario:

5 kids are walking on the sidewalk while you're driving past them. But suddenly a large dumpster is blocking your view of them just as you pass. You saw them before the dumpster, but not after your car and the dumpster completely blocks the view.

Does a human brain carry some worry that they suddenly decide to run and try to cross the street after the dumpster?
Does Waymo carry that worry or just continue to drive at the exact same speed.

Again, it's not like every driver will think about this, but many drivers will (even the bad ones).

"throwing in the towel" would be a "I would do my job but I am forced to cheat the numbers otherwise I lose my job".

I was thinking more to a "I am grateful to my father's cousin for giving me a comfy job where I don't have to do much of the day, of course I am going to return a favor" kind of situation. Of course it is not always this way, but it is fairly frequent.

This is in particular true for those countries whose borders where designed not around ethnic lines but arbitrarily by external forces. The loyalty is to the clan, not to the state.
