> Artificial Intelligence researchers have been trying to get [X] to [Y] for over 65 years

For 10,000 different problems. A great many of which have been solved in recent years.

Robotics is improving at a very fast clip, relative to most tech. I am unaware of any barrier, or any reason to infer there is one, for dextrous robots.

I think the primary difference between AI software models and services, and robotic AI, is economics.

The cost per task for AI software is .... very small. And the cost per task for a robot with AI is ... many orders of magnitude over that.

The marginal costs of serving one more customer are completely incomparable.

It's just a push of a button to replace the "fleet" of chatbots a million customers are using. Something unthinkable in the hardware world.

The seemingly lower level of effort and progress is because hardware that could operate in our real world with the same dexterity that ChatGPT/Claude can converse online, will be extremely expensive at first.

Robotics companies are not just focused on dexterity. They are focused on improvements to dexterity that stay within a very tight economic envelope. Inexpensive dexterity is going to take a while.

What kinds of PCBs are you thinking to auto-route?

If you are talking about a typical hobbyist board with very low frequency switching, the problem is relatively simple, particularly if you allow more than two layer boards. Even there you can create massive problems if you do power distribution wrong.

On the other hand, if you are trying to do something with high frequencies, the problem will be much more difficult. For example, many high speed analog-digital converters use low voltage differential signalling (LVDS) to move data around. Such signals are very sensitive to bad routing since they must be kept very near each other (to avoid creating an inductive loop sensitive to external signals) and must have the same length (to retain common mode rejection). Similarly, RF amplifiers will often oscillate badly or have much lower bandwidth if laid out incorrectly.

the view of social media as just data that can be rehosted i think misses a large part of its success

Twitter and Instagram are fundamentally different scenes bc of their restricted formats. Twitter has/had character limits. Instagram was primary for photo sharing. if you try to cram a long political rant in an instagram photo or description.. it is fighting against the app format and limitations. This sculpts the apps "culture"

im sure it can work, creating a hodge podge of random unstructured content.. like the blogosphere or Facebook. But it wont displace the walled gardens. You can make a Kiki app that only shows images, but youre following someone who is using Booba app which allows him to post pictures with descriptions. And suddenly nobody really knows what to expect

The link to the IBM RISC paper didn't seem to work and I'm not sure if this is the paper that they're linking to since it is from 1990, but I found one of IBM's paper on RISC: https://sci-hub.se/10.1147/rd.341.0004

What I didn't realise is RISC existed and was an initiative by IBM prior to Dave Patterson research and coining of the term.

I'm trying to link to Philip Glass. This could take a while. Kinda fun and a bit reminiscint of googlewhacking or maybe the LLM equivalent of Six Degrees of Kevin Bacon, but it's gonna be way more than six to get to Philip Glass.

Edit, well shit looks like there is a Minimalism page, but it didn't make any names clickable. Sean, looks like you need to tweak the code a bit?

> This decision came after Illinois Secretary of State Alexi Giannoulias discovered that Flock had allowed U.S. Customs and Border Protection to access Illinois cameras in a “pilot program” against state law, and after the RoundTable reported in June that out-of-state law enforcement agencies were able to search Flock’s data for assistance in immigration cases.

Well it's obvious then that if it's helping to deport illegals, then keep going!

What is your threat scenario? Russia marching on EU capitals? After the showing in Ukraine I'm fairly confident that Poland alone with moderate support could put a complete stop to that. They are still growing and modernizing their land forces, but Russia has plenty of losses to recover from, too.

But I feel that argument almost supports my point: If you think Poland/Germany urgently needs more armored vehicles, then spending taxes specifically on that is way more efficient than subsidising the local bus industry.

Isolating yourself is also straight up painful economically, and you also lose a soft way of de-escalation/prevention. I'm not convinced that's a net gain.

Aggregate numbers also don't look that bad to me from a Europe vs Russia point of view; if you sum up vehicle numbers for European countries the gap is no longer that big, and European inventories are on average more modern/capable, too.

How much growth in those numbers would you like to see to be able to sleep at ease?

Parody subreddits have a bad habit of becoming serious.

I think the big surprise of the internet and subsequently the SCP wiki's focus on cognitohazards and "killer memes" is that the phenomenon in it's own way is an extreme version of a real danger - as a species we are really not well equipped for the information environment we've built, and it's prudent to tread very cautiously.

From TFA: But wait, there’s more! As you probably know, people in some countries write their dates out with the day before the month. In that case, 27 September, 2025 would be 27/09/2025. If we run the same trick as before, 27/09/2025 turns into 27,092,025. Lo and behold, that is the square of 5,205—5205 times 5205 is 27,092,025.

Funny how these rich people's solutions for national growth [1] always end up enriching them instead of the nation. To make a nation grow as a net producer, two things are needed. Improve the availability of capital for setting up production, and encourage its growth by driving up domestic consumption. Both require boosting cash flow in the economy (as opposed to hoarded wealth). And the way to do that is to improve the job availability and the wages. In other words, the employers have to hire more people and pay better wages.

So what happens if you go the other way and cut jobs, cut wages and raise work hours in the name of 'efficiency'? All the extra profits will go to the company owners and shareholders, unless the worker wages raised proportionally at least. Even if the wages are increased, it still means that the cash is reaching fewer people, unless you hire more people - something that they're actively avoiding by forcing the current employees to work harder. Meanwhile, the extra wealth they make this way end up hoarded in some tax haven without contributing to any productive economic activities.

All these talk about hard work, efficiency and competence are for gaslighting the ordinary folks into enriching the oligarchs even further, while they refuse to even pay their fair share of the tax, much less do what's actually necessary to boost the national economy.

This is also a trend in India since just after the pandemic [1]. It's spear headed by an oligarch whose son in law is a former British PM. His infant grandson has more wealth in his name that what any of his employees can hope to see in ten lives.

The really troubling bit in both cases is the messaging. On the first thought, they sound like they care about the nation and that their demand is correct. But it takes a bit a macroeconomic thinking to realize that their advise only enriches themselves at the expense of the nations. This sort of deceptive messaging should be called out and condemned.

I love love love Unsloth and everything they do, so do not take what I am about to say as criticism of them.

But what's the point? GPT-OSS is regarded as a pretty bad open source model compared to the latest deepseek or qwen releases. Most attempts to use Reinforcement Learning or even any kind of post-training fail in that the data you have is of worse quality and quantity than the data that the model was originally trained on. So you get catastrophic forgetting and a model with lower general IQ than before fine-tuning.

This is true btw even if you use lora or better techniques to supposedly "mitigate" catastrophic forgetting. Even pyreft/reft, which in some cases impact only 0.001% of a models parameters, cause these kind of issues in my experiments.

So why should anyone except AI researchers and the big 4 AI providers care about fine-tuning? The vast majority of people who think they need fine-tuning need good quality RAG/Agentic RAG systems, since they can trivially add or remove data to their model (machine unlearning doesn't work yet), also ground models and objectively makes them more accurate, and fully manipulate and manage how it's used in their prompts context. On top of that, vector DBs/embeddings "easily" scale to billions of records.

I’m really impressed by the quality of this post, as others have mentioned. It’s very well written, and the clarity of the drawings adds a lot to the overall explanation.

It perfectly illustrates the old saying: a picture is worth a thousand words.

I had never heard of this protocol before (even though I’ve been using Bluesky since the Twitter/X takeover), but after reading this, I feel even more confident that the migration was the right call.

I have compared instruction following of stock gpt-OSS against stock qwen and the 20B outperformed all others, intelligently following instructions and reasoning about tool calling correctly for tools it hasn’t been trained on. Additionally, it performs like a 3B model because it uses 32 experts. I don’t know where this claim that it sucks comes from but my evaluation of similarly competitive models showed it leading the pack by a lot.

It's more than just importance though.

I had a friend experience a psychotic episode and suffer from delusions. It was more than just, "this is really happening to me". Any suggestions that we offered that they weren't able to refute became part of the delusion. "You're right, it's not the police breaking into my house, it must be the FBI!"

One could argue the opposite, let's take bevy as an example: more popularity could bring in more contributors or more funding which would hopefully result in making a better engine. The same could apply to Mr. Beast videos (more views translate to more money which translate to better production and staff which translate to more or better videos) but the goals are inherently different (maximizing profit which rewards quantity over quality)

It was compelling and original when the concept didn't exist, or at least hadn't been successfully brought to market like they did. In a world where Twitter exists, and has the network, there is nothing compelling about a Twitter clone.

None of these platforms started with a network. They weren't cooked up by evil investors and MBAs looking for a rent-extraction scheme. Nor were they designed by a committee of philosophical experts saying "oh we'll just copy their thing and make it more esoteric and confusing so that maybe one day we can aggregate content from 14 competing Twitter-like platforms and you can switch between them whenever you like!" They were started largely by kids goofing around and making fun things for people.

The soviets had better healthcare funding and lower rates of homelessness. We may be collectively richer than the soviets, but our state hates us more, and the people who run most of this privatized country (ie, capitalists—board members, executives, and rich shareholders) have more contempt for us than soviet politicians and apparatchiks ever could muster.

Never trust anything written by lawyers/economics/MBAs on climate change - only analysis by chemical or mechanical engineers is worth reading.

Methane pyrolysis is an old technology from early days of oil refining for production of hydrogen & Ammonia/fertilizer/Methanol. it yields half as much H2 than SMR/ATR so it can't compete on cost, unless there is carbon tax/CO2 penalty. Also, coke produced by pyrolysis is lower quality than that produced by Delayed Coking of crude oil refining.

Most of the comments seem to confuse pyrolysis (no O2) with reforming (H2O), which produces CO2. ATR uses partial O2 & H2O and is more energy efficient & cheaper.

Commonsense should tell you e- generated by H2 can't compete with CH4, because Ch4 is the feedstock & H2 is the product!

Thumbs can get overuse injuries: https://getreuer.info/posts/keyboards/thumb-ergo/index.html

I have used ergo keyboards with thumb clusters for several years now. After a while, even though switching to a split ergo keyboard alleviated wrist pains, I developed thumb discomfort.

In the end I solved it by only frequently using the resting key of each thumb (space and backspace). And using the other thumb keys for infrequent things. I use homerow mods to have all modifiers in the alpha block.

if you find one you like it's a massive difference in how much usage you can get out of your thumbs while typing

Until they start to hurt. It can take a few years (just like wrist pains). Be careful!

> They were funded.

No, they weren't. There was never a point in the history of social security where you could continue making the payments to existing retirees on the basis of the saved up money they paid in themselves so that a future generation could decide that they would prefer to both not pay into and not receive social security.

There have been years when working people paid more into the program than retirees withdrew, i.e. when less than all of the money paid by the current generation went immediately to the previous generation, but that money was never even close to enough to fund the promised future payouts.

Moreover, Congress "borrows" the money in the sense that the Social Security Administration holds it as government bonds rather than cash, but then the Social Security Administration gets the interest on the bonds.

The problem is, that was never even close to enough money either way, because the program was configured from the outset to transfer most of the money from current working people to current retirees instead of investing it at interest in order to make the future payments to the people paying into it. This could have been slightly better if the "trust fund" was invested in stocks rather than government bonds because they pay more interest, but it still wouldn't have been near enough. And if even that was the case then the government in those past years couldn't have spent as much money because it would have lost that huge sink for government debt, in which case all the people currently collecting social security would have had to have paid higher taxes for the level of government services they received.

Meanwhile using the money from existing workers for existing retirees not only doesn't actually fund the program, it only even fails to implode as long as you a) never intend to wind the program down and b) the ratio of working people to retirees never decreases. But the ratio of working people to retirees did decrease, because people started having fewer kids and living longer, so now the unfunded "trust fund" isn't just insufficient to make the payments to the people who are currently paying in, it's soon not even going to be able to make the payments to the people who are currently retired, because it's now shrinking rather than growing as a result of more people collecting for each one paying in.

Not sure why people are downvoting this. This is a serious concern and quite a lot some people using thumb clusters develop thumb discomfort or pain: https://getreuer.info/posts/keyboards/thumb-ergo/index.html

In my experience (having also had thumb discomfort on ergo boards) thumb clusters can be great, but you have to make sure to avoid too much thumb movement.

> Even looking purely at the financials, diesel is fucked. > My takeaway: No reasonable assumption exists that would make operating battery electric busses more expensive than diesel ones.

The problem here is that these were your initial opinions that aren't supported by the reality. Diesel is fucked, long term, and that's good, but that's also long term future, not the reality right now like you were arguing. The matter of time is sometimes the matter.

Even if you're right about all of this it still doesn't refute my "fine-tuning doesn't work for 99% of customers including you" thesis.

Also, most mainstream AI benchmarks do not agree with you:

LLMarena (https://lmarena.ai/leaderboard) has GPT-OSS 120B as #53 and GPT-OSS 20B as #69 (nice), which is extremely far from leading.

DeepSeek V3.1 is ranked #9, and is a solid 60+ elo points above GPT-OSS.

I know you're going to link some of the "ya but chatbot arena sucks cus of theoretical attacks against it" paper and the llama4 debacle, but here's more evidence that GPT-OSS blows:

https://livebench.ai/#/?q=GPT-oss

GPT-oss global average: 54.60

Deepseek V3.1 thinking global average: 70.75

Qwen 3 32B global average: 63.71

So bring receipts next time because I did.

Right, your number 1 is quite compelling to me - a lack of standard vocabulary for describing architecture/performance. Most programmers I work with (myself included sometimes) aren't even aware of the kinds of guarantees they can get from databases, queues, or other primitives in our system.

On the other hand 3 feels like throwing the baby out with the bathwater to me. Being so malleable is definitely one of the great features of software versus the physical world. We should surely use that to our advantage, no? But maybe in general we don't spend enough energy designing safe ways to do this.

I tend to be a fan of methane for its high hydrogen content per unit carbon as well as how much easier it is to store than hydrogen. However the argument against methane that I do find convincing is that the infrastructure for transporting and distributing methane leaks a lot. The argument is most compelling against residential distribution, where maintenance is harder to justify, but large leaks regularly occur, and that is very bad for greenhouse emissions.

I’ve always been curious about generating methane in industrial composting or from landfills and using it onsite for hydrogen generation. Not sure if the generating capacity is enough though, there is probably a reason it isn’t being done.

Lots of business decisions are based on “we prefer to use this model because it’s from OpenAI”, not necessarily because it’s the best.

I’ve also seen a lot of enterprises suddenly invest in fine-tuning their own models, even though there is absolutely no reason they should be doing that. But because there’s a huge “we need to do something with AI” directive from the top. Eg “if we fine tune an AI model to understand our custom query language it will prevent our data scientists from taking down production databases”. This is an actual example I encountered just last week.

So if there’s a point, it’s probably not that it’s the best idea, but rather than enterprises are willing to buy it.

Runner up is the glove 80, but the only thing is I don't like how flimsy it feels in my hands compared to how solid the kinesis feels.

Glove80 has a better key well and thumb cluster for most people though. I have made a detailed comparison here:

https://danieldk.eu/MoErgo-Glove80-Review

Also agree with the sibling commenters. In order, get:

- Help from an expert/exercise/do very regular breaks.

- A properly adjustable chair.

- A height-adjustable desk (get an electronic one, it's the only one you will ever tune properly, other desks are too much effort).

- Only then an ergo keyboard.

An ergo keyboard is worthless if you do not get the basics right (diagnose the issues, letting the blood flow, having a good posture). I am in some ergo keyboard Discords and it happens far too often that people by an ergo keyboard, but do not even have a setup where they can have a good posture.

What does the contract or the law say?

The “Feds asked nicely” doesn’t change the law. I worked for a company that processed state income tax data. Improper disclosure was a felony punishable by 5 years in prison.

Regulating interstate commerce doesn’t give the content the power to renegotiate state contracts or dismiss state law.

My biggest blockers to switching to Asahi were mic and camera support, and video out (hdmi or usb c). Once all that was supported, I immediately switched over and it felt great to finally be running Linux again. But, it seems I totally glanced over the battery, battery performance is not great at all on Asahi, and unfortunately I'm back in macos again waiting for this issue to be resolved: https://github.com/AsahiLinux/linux/issues/262

Amazing work so far everyone!

> Before too long (and we already start to see this) humanoid robots will get wheels for feet, at first two, and later maybe more, with nothing that any longer really resembles human legs in gross form. But they will still be called humanoid robots.

Totally agree. Wheels are cheaper, more durable and more effective than legs.

Human would have wheels if there was an evolution pathway to wheels.

I didn’t ask for your help other than accepting other opinions exist. In some cases the distinction is of high value. In some cases it’s at low cost. I’m of opinion this is low value and high cost, thus the cost benefit analysis fails. You’re free to disagree.

Cop uniforms are low cost and serve a significantly higher purpose. Taxis being a distinct color is unnecessary too. If I can identify a Dominos delivery vehicle from a distance, than they just need to try harder with their lit signs. A simple redesign could render vehicle paint job obsolete. Just because it’s been that way doesn’t mean it is the best or only solution and it certainly doesn’t mean it has to remain that way.
