bob1029··on The Components of Agent Memory
Their progress toward cerulean chart is selling me pretty hard on no memory.

The biggest thing I want to avoid with a long running agent is volatility. Anything that pushes it into one direction or the other that quickly is not desirable in the average case. At least not to me.

bob1029··on GitHub's new Git storage architecture
I think perforce might be the better VCS if you intend to have a bunch of autonomous agents attempt to collaborate over one big pile.

Multiple terabytes is no problem out of the box. You get exclusive locking of files. You can easily take partial checkouts of the monolith. Centralization is a feature in this particular context. Git works great if the need for coordination is moderate. If you've got thousands of automated developers with their hands in the cookie jar, exclusive locks start to look really compelling. Perforce sucks with a highly distributed team, but in the case of an AI agent swarm we presumably have the ability to instantly nuke an agent's checkout if needed. I don't have to contact the agent and wait for them to get out of bed.

bob1029··on Memorilla: Latent Semantic Memory for LLMs
I am finding that semantic ~= lexical when you have something like a frontier model driving. Using full text search engines is still the most compelling approach for handling large document sets.

I really struggle with the semantic / embedding concerns when we have a generative model that can reverse engineer a Mario 64 rom dump to run on my toaster oven. These models know how to compose Lucene & other FTS query strings in such a way that we are effectively getting semantic search over purely lexical systems.

bob1029··on Tesla to wind down Cybertruck production
What are the chances that the supercharger station even has power after a hurricane? You want something that is already on the property. I've had roads blocked by fallen trees for days after a windstorm event.

If you are concerned about riding through a 14 day+ event you need a generator. Even a fully off-grid solar / wind setup could be compromised in these kinds of storms. I've seen entire roofs cleaned off by a <100mph storm. Anything not bolted down to a concrete slab cannot be depended on.

bob1029··on Closed AI models dominate the price-performance frontier
gpt-6.1-terra has some pretty crazy economics.

I don't think I am going to try to beat them at this game anymore. I've got a machine in my closet that is both collecting dust and accruing value. A very maddening state of affairs.

At this point, trying to beat a major provider is like running your whole house off grid when the alternative is 12c/kWh that is already wired to the premises. You might win if you make it your only job for years on end and have a very specific lifestyle that is tolerant to weird tail risks (assuming you aren't willing to go back to the grid in an emergency).

bob1029··on Claude Code sends your email address to websites
Stuff like this is why I use API tokens and custom harnesses.

CC and Codex are like contemporary televisions. You are the product in this arrangement.

bob1029··on Building a Multi-Agent System from Scratch: Architecture Patterns
Custom harness, custom tools.

With custom we don't have to disclose to the caller that the implementation of the tool is another LLM. Each piece of deterministic tool code can firewall the perspective of the model as appropriate.

Think of a sub agent as being isomorphic with a tool call.

bob1029··on Building a Multi-Agent System from Scratch: Architecture Patterns
I am curious if we have any examples of problems that can only be solved via multiple concurrent prompts coordinating in real time.
bob1029··on Building a Multi-Agent System from Scratch: Architecture Patterns
Sub agents are significantly more useful than multi agents.

Wrap a nested prompt with a tool call that is invoked by the caller prompt. That is the answer to all your suffering. You can repeat this for as many layers of invocation as you desire. You can layer determinism and non-determinism as much as you like in whatever orders you see fit with additional alignment, retry policies, logging, etc.

Agents running concurrently will not go any faster than one well-designed hierarchical agent system.

Imagine the simple task of incrementing a global counter. That would be my #1 benchmark. If you can demonstrate a MAS can increment that counter faster than a single agent can (monotonically without skipping), then I will happily delete 100% of the AI-related code I've authored and start over using your ideas.

bob1029··on Are Drone Ports the Next Annoying Neighbor? Flying delivery bots prompt concern
Why do we need shit to be delivered this quickly?

I can have my groceries delivered same day via multiple parties. I can have many things from Amazon on my porch the next morning without resorting to aerospace. FedEx can get pretty much anything else to me within 2 days (sometimes involving aerospace).

Where is the demand for this coming from? Does HN feel a burning urge to consume something so essential that it must be delivered now? What the hell is this? A hankering for some snack crackers and a Lego set? Is the demand genuine? I can't help but feel like sometimes this technology is bad on purpose just to antagonize. Like 7000K LEDs being sold to other humans. Evil exists in many formats. Technology companies bring hyperscale to the activity of spreading misery.

bob1029··on Insects don't swarm at LED lights
They can. It's either ignorance or malice. It's not economics.

bob1029··on Ask HN: What's your current AI agentic setup?
Copilot in VS2026 + GPT5.5 configured as a custom model (API Tokens). Same as it was 6 months ago.

I really want to use 6.1 Terra, but the way copilot is set up in visual studio proper, they don't handle reasoning models correctly (or maybe my install is screwed up). Eventually, I will dust off that old winforms project and get my custom harness working with the latest responses API contract.

I prefer (pre) paying for tokens. You can offer me all the proof you want but I'll still never believe that those subsidized tokens are always the same as the ones I get through the API.

bob1029··on A wave of plastic-free coffee pods and machines
When I drank coffee I would use a Hario V60. Avoiding plastic is trivial (and cheap). $40-50 for the entire setup. I preferred to waste my money on expensive beans instead.
bob1029··on How I use AI (Oct 2026)
> I also now reckon with the fatigue of using these agents. Managing 6 different conversations with 6 different robots about 6 different features is overstimulating & exhausting in a way that coding never was.

Anyone using a swarm of agents in November 2026 to write code is no longer at the frontier of capability.

Running multiple system prompts at once is a perfect example of anthropomorphism. We have this fantasy that a community of diversely aligned agents will somehow outperform a single well-aligned agent. There might be some cases where the random walk takes you where you want to go, but how stable and stressful do you want it to be?

Some of us are using AI as a means to make a living now. If I slip even a little bit on best practices my clients will likely turn into ghosts. Multi agent is an extremely expensive form of entertainment in this context. It's the entire basis for why we have these junkies trolling around HN complaining about how they can never get enough tokens. If I was still playing with these ideas in front of my customers I can guarantee I'd be 100% unemployed right now. They brought me in to make AI into a profit center, not a cost center.

bob1029··on xAI installs eight converted jet engines to power Mississippi data center
I know this is not a great application, but the Brayton cycle really is quite amazing from an engineering perspective. The amount of power we can generate per unit of volume or mass is incredible. That's why they keep using these damn things. To get a sense of scale, the new GE helicopter engine can produce 3000 shaft horsepower (~2.2 MW) and it only weighs around 200kg. A commercial truck in the US can haul 20,000kg worth of mass before requiring a babysitter.
bob1029··on Embedding boolean circuits in a neural network
Symbolic AI (of any type) is still a holy grail objective.

I think linear program tapes are the best substrate if we want to diversify our architectures. Massive GPU farms have definitely won at the neural network game, but they would struggle to execute a highly branchy piece of code faster than a humble single core CPU.

Sequentially following a series of register-based instructions that produces the same effect as Astra would be an unbelievable accomplishment. There is still no conclusive evidence that this type of system cannot be produced. The search space is so awful (on paper) that people rarely try. You have to be a little bit crazy to spend time on this stuff in 2026. However, you will often be rewarded with unexpected results. Never underestimate the power of a good fitness function when combined with 1v1 tournaments and large populations. Even a ridiculously simple ISA can produce amazing results under sufficient evolutionary pressure.

With a Turing machine, you don't need to find the global minimum. That is a strong anti-pattern. You just need to find one of countless really good minima. The search space is not one needle in one very big haystack. A meaningful percentage of the hay is needles.

bob1029··on Fujifilm to boost tape production 5x as AI fuels archiving demand
The big cloud providers use something like erasure coding across a collection of tapes (or hard drives) to preserve information. If you've ever downloaded something from usenet and restored it with quickpar, this is basically the same idea. Every physical cartridge gets a chunk of the file. Depending on parity settings you would have to lose many tapes distributed across an arbitrary # of locations to actually lose any data.
bob1029··on Anthropic's IPO Filing Warns It May Be 'Imminently' Close to RSI
Knowing what I know about publicly traded companies and their willingness to bend roadmaps into contorted pretzels, this is not how an "imminent" RSI capability would be advertised to the market.

If it was truly imminent they would claim they already had RSI. That is how the game works. Take a look at IBM and quantum if you require an additional sample. Review the things these companies strongly imply they can do relative to what they can actually do. Anthropic is arguably making less aggressive claims with this RSI narrative.

The lies flourish in the definitions behind these terms. When Anthropic says "RSI" and IBM says "Quantum", they are invoking a highly curated lawyer routine that has a mountain of legal documentation surrounding it.

bob1029··on Astra can read and write weights to improve Qwen
If we are being slightly reductive, this is just more of the exact same thing. The token stream in this case happens to be a projection of the weights of a neural network. I don't see where we violated any of the prevailing assumptions about how these systems operate.

The mapping between spaces in this case is mostly linear. This isn't like gzip or a Turing machine. I'd argue this is even more permissive (easier) than the LLM's originally intended use case of human language.

What happens if we can come up with a model that can directly emit a frontier LLM given some seed context? I feel like we could train a model to recreate astra verbatim. At some level it's just bytes on a disk that can be bundled up into tokens. As long as the representation is rational and consistent I don't see why this wouldn't work.

bob1029··on Scaling Git at OpenAI
Why not use a completely different VCS topology if you are a gigantic trillion dollar behemoth? Why are we still using the "distributed" git concept as the basis for everything?

Centralization is exactly what you want at this kind of scale. The most marginal participation from the server would make a huge difference.

There is a reason game studios don't use git. It's not just about the large objects.

bob1029··on BioWare co-founder: game execs "have never made a game" and don't get it
> I'm not sure how AI could destroy the demand here.

By overwhelming the supply. How can a consumer keep track of what to play anymore?

As an example, I didn't even hear about PBZ until you mentioned it just now. The fact that Valve might occasionally select lottery winners is separate from other forces involved. I would hesitate to highlight the occasional breakout (artificially-promoted) success as some kind of evidence that there is nothing to see here.

> They just need to make good games.

If only we could just do that.

bob1029··on BioWare co-founder: game execs "have never made a game" and don't get it
I think the best answer is AAAA+ scale projects. AI has destroyed the demand for something that can be produced in a few months. The "meso" scale of game development is extremely difficult to work in. Constantly walking a tightrope between too easy and too hard. Rockstar games does seem to have the right idea. They can remain viable by simply never reducing their feature scope and spending unlimited amounts of money.

Perhaps enough indie game studios could align their thinking at the same time to accomplish a similar outcome. In any case, pooling of talent and resources is probably the only way to compete now. The individual developer simply cannot keep up despite being able to do more than they ever were before.

If you seek evidence of Jevon's paradox I think you may find it here. Albeit in a very undesirable form. Even if I can now do 100% more work per unit time, my prospective customer is demanding 300-400% on top of that in terms of the final delivered experience. The water level has gone up everywhere and continues to rise rapidly. Even outside of game development. Deliverables that would have elicited reverence from the business twelve months ago are completely unrecognized now.

bob1029··on Ask HN: Which TV do you recommend for privacy?
It's not hard to find options if you stop looking in stupid places with bad search terms. "TV" on Amazon is literally the innermost circle of consumer hell.

bob1029··on I Am the Reason OpenAI Is Killing Unlimited Chats
> Since ChatGPT chats cannot spawn or control subchats/subganets so I had to be a bit creative in order to do multi-agent development and orchestration.

Multi-agent is mostly dead. One big agent loop running GPT6.1 absolutely dominates any weird ideas like this now. I still use sub agents for some tasks where I want to compress the action space and context. For example, testing a workflow that requires 100+ tool interactions for each logical test. Without a subagent it's really hard to guarantee a test makes it E2E. I have some very "persuasive" methods for long horizon tests that would break the main loop's dynamics.

We may not feel so compelled to exploit the system if we could figure out how to not be so wasteful. Multi agent schemes can bloat token usage by orders of magnitude. They force us to consider consuming less ideal tokens from contexts and vendors with higher variance.

HN loses its marbles when I suggest it's economically feasible to prepay for API tokens and use these as the exclusive means of performing AI work. I get done with a thousand tokens what my peers cannot do with a million. It doesn't matter how many hammers or workers you have if you don't have the aesthetic preferences and domain expertise to employ them correctly.

bob1029··on Bidirectional charging during grid outages
The biggest issue is any wind damage to the roof. If it's leaking even a little bit, it's going to be leaking hard for hours.

With a consumer dehumidifier you might get 5-6 gallons per day. A 5-ton HVAC system will pull over 50 no problem. You might have hundreds of gallons of water soaked throughout the framing, drywall, insulation, etc. It can take a really long time to remediate without a powerful HVAC system.

bob1029··on Bidirectional charging during grid outages
> For the vast majority of the population

In the spirit of nuance, the vast majority of the population of Florida is at risk. Something like 10% of the US population in total could be impacted directly. You don't actually have to live on the coast to get rocked by a hurricane. Ike took out power for millions in Ohio.

I found this to be unusually good. I got caught in a rabbit hole about interpretation of the work of Bach. I would have never seen this stuff in the YT interface.
bob1029··on Bidirectional charging during grid outages
My biggest problem with batteries for grid outages is that the only outages I am actually concerned with would drain them to zero before the outage is resolved. For short term, smaller/portable batteries are fantastic at bridging a few hours. Plug the wifi & fridge in and you can sometimes go for 2-3 days.

I am not aware of any economically feasible way to run my 5+ ton HVAC system full-time on batteries after a hurricane just reset all the infrastructure, and you do need to run it full time because of the insane humidity and latent heat that follows a tropical system. Doing the math, I'd need something approaching 800kWh of storage to ride through this kind of event (7+ days). This is approaching half a million dollars in batteries. I can install an extremely nice 1800 RPM generator for ~15% of this cost, which would also include a year's worth of propane buried on the property.

I think a simple generator on an ATS remains undefeated from an engineering perspective. If you have an air cooled unit, the maintenance is not much more complicated than with a lawnmower. You just have one extra spark plug to deal with, and sometimes the oil pressure sensor needs replacing. I can get my stubborn Honda generator to start with all kinds of weird tricks. If my Ecoflow battery starts to act weird, I have very little recourse by comparison.
