I like to think of subagents as “OS threads” with its own context and designed to hand off task to.

A good use case is Cognition/Windsurf swe-grep which has its own model to grep code fast.

I was inspired by it but too bad it’s closed for now, so I’m taking a stab with an open version https://github.com/aperoc/op-grep.

> "In our 2023 reliability survey, 17 percent of 2013 Tesla Model S owners told us their cars needed battery pack replacements at a cost of $15,000 each."

What was the remaining range for those replacements?

> Granted, perhaps batteries were just crappier back then,

Tesla makes its own batteries right? When did that start?

> but 17% is a scary high number for me.

Is that high? I have no idea. How many ICE powertrains got replaced at the same time and what did it cost?

I have been independently thinking about a lot of this for some time now. So this is so exciting for me. Concretizing _skills_ allows, as you said, a common pattern for people to rally around. Like you, I have been going dizzy about its possibilities, specially when you realize that a single agent can be modified with skills from all its users. Imagine an app with just enough backbone to support any kind of skill. From here, different groups of users can collaborate and share skills with each other to customize it exactly to their specific niche skills. You could design Reddit like community moderation techniques to decide which skills get accepted into the common repo, which ones to prioritize, how to filter the duplicates, etc.

These data points are based on 2023 inflated pricing as the entry point. Not much to see here.

In 2023 the car market was wildly overpriced due to the low interest rates and covid money combined with supply chain problems.

I'm happy to have popups with "Reject All" button. If there is no "Reject All" button I close site immediately.

Cookie regulations are perfectly Ok, businesses which want to add 429 vendors and data processors to simple internet shop or corporate blog is not.

If you use cookies only for legitimate basic local functionality (like login and shopping cart on online shop site) you SHOULD NOT have any popups, there is exemption for such use cases in the regulations. Only if you want to sell data or pass it for processing to third party you need popup. Simply don't.

The out of work tradesman going into the Fairfax VA or Berkley CA Whole Foods (IDK if either of these places have Whole Foods, but they seem like they could) in the year 2030 and dusting the avocados with anthrax won't care whether the anthrax is funded by China or Russia, just that it winds up in the lungs of the people who've run his country into the ground.

I think you are confusing breaking a law, and enforceability. I agree with the gist of your argument though, the UK cannot _force_ a US only company, but it doesn't change the fact it is breaking UK law.

> I likely would be breaking DPRK law. Why wouldn't they have the power?

They do as a sovereign nation. But what most people seem to be missing is that you're not going to DPRK and the US Government doesn't care so you can go about your life breaking DPRK law as much as you want.

The economy is a lie. There is no the singular, hive mind economy. There are several segments and it's growing ever lopsided and moving K-shaped. The so-called "precariat" are hurting very badly. It doesn't matter what sort of imaginary, incestuous valuations NVIDIA et. al. attain because it doesn't trickle down in any measurable fashion. There is an pervasive profit-price spiral of necessities is a huge contributor of ongoing and deepening inflation. And the random tariffs / punitive federal sales taxes are yet another inflationary policy. The ultra rich can and will deny technological un(der)employment is happening until the pitchforks come out, and then blame the poor for being lazy/stupid/slow/unfortunate/antifa/whatever.

> It's a hard problem

So people say.

I’m not sidestepping the Hard Problem. I am denying it head on. It’s not a trick or a dodge! It’s a considered stance.

I'm denying that an idea that has historically resisted crisp definition, and that the Stanford Encyclopedia of Philosophy introduces as 'protean', needs to be taken seriously as an essential missing part of AI systems, until someone can explain why.

In my view, the only value the Hard Problem has is to capture a feeling people have about intelligent systems. I contend that this feeling is an artifact of being a social ape, and it entails nothing about AI.

Notice how pricing is the top discussion theme. People love free shit and it's hard to deny codex usage limits are more generous. My 2c for someone who uses both tools pretty consistently in an enterprise context:

- Codex-medium is better if you have a well articulated plan you "merely" need to execute on, need help finding a bug, have some specific complex piece of logic you need to tweak, truly need a ton of long range context to reason about an issue. It's great and usage limits are very generous!

- Sonnet 4.5 is better for everything else. That means for me: non-coding CLI ops, git ops, writing code with it as a pair programmer, OOD tasks, big new chunks of functionality that are highly conceptual, architectural discussion, etc. I generally approve every edit and often interrupt it. The fast iteration and feedback is key.

I probably use CC 80% of the time with Codex the other 20%. My company pays for CC and I don't even look at the cost. Most of my coworkers use CC over Codex. We do find the Codex PR reviewer to be the best of any tool out there.

Codex gets a lot of play on twitter also because a lot of the most prolific voices there are solo devs who are "building in public". A greenfield, solo project is the ideal (only?) use case for running 5 agents in parallel or whatever. Codex is probably amazing at that. But it's not practical for building in enterprise contexts IMO.

> Right now, commercial rents are locked into untenable rates because the loans are contingent on those rates

Let me get this straight.

A landlord cannot lower the rent, because they took out a loan on the property which promised to the lender that the rent is a particular amount?

> which is resulting in 30%+ unused commercial space in areas like downtown SF.

The loan prevents the landlord from lowering the rent, so the landlord realizes rental income of $0 on the property.

Oh, that's just great.

> He’s a physicist, mathematician, and logician

You just placed biology and neuroscience firmly outside of his wheelhouse. Just the size of the structures involved, temperature, timescales, and distance between neurons alone is a serious problem with his theory here.

If he is approaching things from a purely hypothetical standpoint it’s an unlikely but reasonable idea, but it utterly fails as part of how a larger system we actually understand quite a bit about works. Which is always the hard part of science, you’re not just fitting a single curve but thousands of different datasets.

Because there's a lot of evidence that people tend to overestimate/overstate how useful LLMs are.

Everyone says "I wrote this thing using AI" but most of the time reading the prompt would be just as useful as reading the final product.

Everyone says "I wrote this large codebase using AI" but most of the time the code is unmaintainable and probably could have been implemented with much less code by a real human, and also the final software isn't actually ready for prod yet.

Everyone says "I find AI coding very useful" and neglects to mention that they are making small adhoc scripts, or they're in a domain that's mostly boilerplate anyways (e.g. some parts of web dev).

The one killer application of LLMs seems to be text summarization. Everything else that I have seen is either a niche domain that doesn't apply to the vast majority of people, a final product that is slop and shouldn't been made in the first place, or minor gains that are worthwhile but nowhere near as groundbreaking as people claim.

To be clear, I think LLMs are useful, and I personally use them regularly. But I've gained at most 5% productivity from them (likely much less). For me, it's exhausting to keep on trying to realize these gains everyone is talking about, while every time I dig into someone claiming to get massive gains I find that the actual impact is highly questionable.
by TeMPOraL | 2025-10-17 23:07:52+00:00
They're much more useful when an LLM stands between them and users - because LLMs can (re)process much more of them, and much faster, than any human could ever hope to.

One way (and one use case) of looking at it is, LLM agents with access ("tools") to semantic search[0] are basically a search engine that understands the text it's searching through... and then can do a hundred different things with it. I found myself writing better notes at work for this very reason - because I know the LLM can see them, and can do anything from surfacing obscure insights from the past, to writing code to solve an issue I documented earlier.

It makes notes no longer be write-only.

[0] - Which, incidentally, is itself enabled by LLM embeddings.
by ACCount37 | 2025-10-17 23:08:00+00:00
And we can barely figure out how the modern LLMs work.

That doesn't bode well for minds being human-interpretable, not at all.

I used to think that the biggest bottleneck to understanding the workings of the human brain was that it defies instrumentation. Which could be solved by better imaging techniques, high throughput direct neural interfaces, etc. But looking at the state of AI now?

If we had full read/write access to the state of every single neuron in the brain, what would we be able to learn? Maybe not that much.

I still find it strange how people use the word “WiFi” to mean internet. For so many young people today, WiFi IS the internet. They have never plugged in an Ethernet cable in their life.

I still get frustrated by WiFi, though, and never use it for my computers unless I had no choice. So many devices these days, the performance is still subpar. Packet loss on the best connections cause so many performance degradations.

Since we’re pulling numbers out of our ass, I think AGI is 500 years away. But really, I don’t know how we’re going to define it, but if AGI means computers can outperform me at all cognitive tasks, I’d bet money that’s not going to arrive this century.

People are starting to get catch on, but most non-tech people don’t use LLMs for anything more than simple questions that can be easily answered by summarizing regurgitated snippets of training data. To them, it looks intelligent. And yeah, the humans who wrote the training samples it regurgitated probably were intelligent.

It’s just a fact, one that becomes glaringly obvious when you use LLMs daily to do real work, that this is just not the tech that will lead to AGI.

They found a really clever pattern matching technique that, when combined with absurd amounts of data and compute, can reproduce plausible summaries of training data which can be stitched together in useful ways. It’s a useful tool. But the whole AGI conversation is so absurdly far away from this that it’s just clear that these guys pushing a very dishonest grift.

It's a fun problem to think about. [1] I don't have a computer science background, so I appreciate you bridging the gaps in my knowledge.

I mostly understand what you're suggesting (I'd need to read up on how each individual algorithm works at a low level). It's true that most of the sprites would remain in the same order and in theory it would be worth looking into this (it may benefit low powered machines -> widen the potential market).

However, there are other limitations with the framework I'm using that make me pause. I'm using OpenGL and Vertex Buffer Objects (semi-dynamic Vertex Arrays, ie. a std::vector<> of vertex information that the GPU can store locally). When a vertex array is updated, the entire array must be resent to the GPU, or alternatively one can do individual range updates (which... are not working at the moment). There can be so many sprites on the screen that a full update would cause the FPS to drop (learned this by example). And since CPU -> GPU communication is so costly, I assume hundreds of individual updates would also drop the FPS.

With my custom depth maps for each sprite, the vertex array only needs to be sent once. (Side note: the world is broken into 40x40 chunks)

> If the only way to get topo sort to work is by treating the sprites as a fully connected graph, then it's not the right approach.

One trick the OpenRCT devs did was split the screen (or scene?) into 64 pixel wide vertical strips. Though they still said the performance was O(N^2) for each strip.

[1] I am content with the engines performance for now. Last I tested I, a very dense scene ran >165 FPS on a medium performance GPU.

> the end result is the same.

Absolutely not.

This completely ignores the relatively high initial range of ICE (especially hybrid), and the poor real world state of the EV charging infrastructure, compared to petrol.

A 30% drop in range would be an extra 5 minutes at the nearest gas station, almost guaranteed to be within a couple miles.

And, that 30% is usually cheap to get back, usually just by some combination of changing the spark plugs, running a bottle of carbon removal/fuel system cleaner through, or changing the fuel injectors.

I have an electric, but I also understand why people are avoiding electric, and why 96% of people with EV also have an ICE car [1] (including me, with my newest being ICE)!

Not even close to right. First of all, the "small generic math problems" given at IMO are designed to challenge the strongest students in the world, and second, the recent results have been based on zero-shot prompts. The human operator did nothing but type in the questions and hit Enter.

If you do not understand the core concepts very well, by any rational definition of "understand," then you will not succeed at competitions like IMO. A calculator alone won't help you with math at this level, any more than a scalpel by itself would help you succeed at brain surgery.

I had to skim through this a couple times before I realized that I still need to run an MCP server locally. This is basically a proxy between an LLM and the proposed protocol.

It’s a nice proof of concept.

And makes sense that the goal would be for LLM clients to adopt and support the standard natively. Then the proxy won’t be necessary.

An online casino got hit a similar way a long time ago, iirc someone realised the seed for a known prng was the system clock, so you could brute force every shuffle either side of the approx time stamp and compare the results to some known cards (I.e. the ones you’d been dealt) once you had a match you knew what everyone else had.

Always thought that was elegant (the attach not using the time as the seed).

> I don't see any evidence that EUR is particularly strong against USD. Except maybe if you take a very short-term perspective.

Yes; this is a short term perspective. Europe is functionally an export market and these currency fluctuations hurt badly. For example, Mercedes-Benz had a consolidated profit margin in '22 of around 9%. These swings do either force loss of jobs (bad) or require a devaluation of the currency.4

> it'll be called Kourier or something

I'll be disappointed if it isn't like Snow Crash (1992):

> The Deliverator, in his distracted state, has allowed himself to get pooned. As in harpooned. It is a big round padded electromagnet on the end of an arachnofiber cable. It has just thunked onto the back of the Deliverator's car, and stuck. Ten feet behind him, the owner of this cursed device is surfing, taking him for a ride, skateboarding along like a water skier behind a boat.

> In the rearview, flashes of orange and blue. The parasite is not just a punk out having a good time. It is a businessman making money. The orange and blue coverall, bulging all over with sintered armorgel padding, is the uniform of a Kourier. A Kourier from RadiKS, Radikal Kourier Systems. Like a bicycle messenger, but a hundred times more irritating because they don't pedal under their own power -- they just latch on and slow you down.

This is, strictly speaking, an improvement, but not by much. You can't change the cipher key because your downstream users are already relying on the old-key-scrambled IDs, and you lose all the benefits of scrambling as soon as the key is leaked. You could tag your IDs with a "key version" to change the key for newly generated IDs, but then that "key version" itself constitutes an information leak of sorts.

No, the average is high because we've lost a lot of our cheap 'new' cars.

10 years ago you could go onto a lot and buy a brand new Dodge Dart for around $17,000.

Today, the cheapest Dodge is a Hornet SUV/CUV for $31,000+; the cheapest Jeep is $27,000.

We just don't have new car choices under $20k -- we're all forced into extremely high loans for 'new', or extremely screwed rates for 'used'.

How did they find F150’s selling for $35k new in 2023? If they’re comparing fleet model F150s either roll up windows to model Ys, that’s an incredibly unfair comparison. You would need to compare similar trim levels with comparable features to a model Y. An F150 with a higher trim has depreciation values similar to an electric vehicle.

>Are you saying that if I had a website hosted in Russia that pretended to be your bank and stole all your money from phishing that is perfectly legal?

Website hosted in US publishing truth about Ukraine war - even calling it a war is already a felony in Russia - is it legal or illegal?

I'm personally against stealing money, and i'm for calling a war a war, yet how do we formally codify that into law - there are 200 countries and at any given moment, especially while online, you're probably violating some law of some country. Before internet globalization, the geography based jurisdiction was such an objective approach. Now it is more like "catch me if you can" which is obviously not a solid foundation to build on. Like that plane that had emergency landing in Minsk, and the Belorussian dissident flying on that plane was arrested by the Belorussian police.

This is actually my theory of the future. Basically, the ability to multiply your own effectiveness is now directly dependent on your ability to express ideas in simple plain English very quickly and precisely.

I’m attracted to this theory in part because it applies to me. I’m a below average coder (mostly due to inability to focus on it full time) and I’m exceptionally good at clear technical writing, having made a living off it much of my life.

The present moment has been utterly life changing.

For anyone new to Charlie Stross' fiction, here are a few links for your perusal:

Stross' 2005 novel Accelerando [1] set around the technological singularity, is made freely available by the author

In addition to various standalone science fiction novels, Stross also has a couple of long series, the Laundry Files and Merchant Princes / Empire Games.

The setting of the Laundry Files is a mix of magic as a branch of applied math, UK secret service bureaucracy and lovecraftian horror. Stross' laundry files novella "Down on the Farm" is available to read here [2].

Stross' early novelette A Colder War, published in 2000, can be read here [3].

The Merchant Princes series is also a great yarn. The setup is that parallel universes with alternate history Earths exist, and tech journalist Miriam discovers she belongs to a bloodline who can "jaunt" into a parallel medieval Earth. One thing Stross does well is applying the science fictional / economic lens of "OK, so if that were true, then what happens?", so instead of simple fantasy tale we get an exploration of stuff like the transdimensional narco-courier-for-guns trade, or what would Rumsfeld do if transdimensional narcoterrorists made a severe error of judgement and picked a fight with the US? The series gets pretty dark...
