Show HN: IntentusNet – Deterministic Execution and Replay for AI Agent Systems
by balachandarmani | 2025-12-27 14:38:34+00:00
Hi HN,

I’ve been working on an open-source project called IntentusNet.
It focuses on a narrow but persistent problem in AI systems:

AI executions are observable, but not reproducible.

When a production issue happens:

the model may already be upgraded

fallback logic may have changed

retries may be implicit

routing decisions are no longer recoverable

Logs tell you something happened, but they don’t let you replay the execution itself.

What IntentusNet does

IntentusNet is not a planner, prompt framework, or model wrapper.

It’s an execution runtime that enforces deterministic semantics around models:

explicit intent routing

deterministic fallback behavior

ordered agent execution

transport-agnostic agents (local, HTTP, ZeroMQ, WebSocket, MCP-style)

In the latest release, I added execution recording and deterministic replay.

Each intent execution can be:

recorded as an immutable artifact

replayed later without re-running models

explained even after models or agents change

The core invariant is simple:

The model may change.
The execution must not.

Why I built this

Most AI systems implicitly trust the model to drive control flow.
That makes failures hard to reason about and almost impossible to reproduce.

IntentusNet takes the opposite approach:

models are treated as unreliable but useful

routing and fallback are explicit and deterministic

executions are facts, not logs

This is closer to how distributed systems treat requests than how most LLM stacks work today.

Demo (what it actually proves)

There’s a small demo that shows:

A live execution with “model v1”

The same execution with “model v2” (different output)

A deterministic replay of the original execution, even after the model changes

Routing and execution order stay the same.
Only the model behavior changes.

No debugger UI, no dashboards — just execution semantics.

What this is not

Not a replacement for MCP

Not a prompt-engineering framework

Not a monitoring system

Not trying to be “smart”

It’s infrastructure for making AI systems operable.

Repo

GitHub: https://github.com/Balchandar/intentusnet

I’m especially interested in feedback from people who’ve had to debug LLM-related production incidents or explain AI behavior after the fact.
Happy to answer questions or criticism.

I've got two RK3588 boards here doing Linux-y things around my place (Jellyfin, Forgejo builders, Immich, etc) and ... I don't think I've run into pain? They're running various debian and just ... work? I can't think of a single package that I couldn't get for ARM64.

Likewise my VPS @ Hetzner is running Aarch64. No drama. Only pain is how brutal the Rust cross-compile is from my x86 machine.

I mean, here's Geerling running a bunch of Steam games flawlessly on a Aarch64 NVIDIA GB10 machine: https://www.youtube.com/watch?v=FjRKvKC4ntw

(Those things are expensive, but I just ordered one [the ASUS variant] for myself.)

Meanwhile Apple is pushing the ARM64 architecture hard, and Windows is apparently actually quite viable now?

Personally... it's totally irrational, but I have always had a grudge against x86 since it "won" in the early 90s and I had to switch from 68k. I want diversity in ISAs. RISC-V would be nice, but I'll settle for ARM for now.

The problem is that fraudsters won't be "producing", but instead will be stealing from others. They need to be in prison not because it's a punishment but because they cannot be trusted to participate in society honestly.

However, I don't think it's practical to get fraudsters to pay back all the money in most cases as they won't be able to. What we need is a faster way to detect and imprison fraudsters to limit the damage they do. Also, most people don't respond to the "size" of punishments, but more to the likelihood that they will be caught.

Great feedback - i take the point on verification on data harvesting, any ideas on solving that?

I think subscriptions could work, people pay not to have ads in other media they consume, ive built a prototype platform, that allows users to curate their life in it, part social network, part journal, part support. i want to also build in safety features for children so parents feel safe letting their children online. would love some feedback on the premise.

in addition to aperture, percieved depth of field greatly depends on:

- focal length (wider is deeper)

- crop factor (higher is deeper)

- subject distance (farther is deeper)

compared to your telescope, any terrestrial photography is likely at the opposite extremes, and at a disadvantage everywhere but subject distance.

but, focus is most mechanically sensitive near infinity. adjustment creates an asymptotically larger change in the focal plane as infinity is approached.

in a point-and-shoot camera with a wide lens at f16, "infinity" basically means across the street.

> Is it -c:v or -v:c?

Sure, I agree with all of this. Like I said above, the syntax (and, even more, the defaults) isn't great. I'm just arguing that "improving the syntax" should not mean "hiding complexity that should not be hidden", as the linked project does. An alternative ffmpeg frontend (i.e. a new CLI frontend using the libav* libraries like ffmpeg is, not a wrapper for the ffmpeg CLI program) with better syntax and defaults but otherwise similar capabilities would be a very interesting project.

(The answer to your question is that both -vcodec and -c:v are valid, but I imagine that's not the point.)

> The biggest problem is open source teams really don't get people on board that focus on customer and product the way commercial software does.

I believe in this case it may be more of a case of backwards compatibility, with options being added incrementally over time to add what was needed at the moment. Though that's just my guess.

I guess I disagree. The ‘easy to spot’ never goes away, regardless of configuration, so long as the conversation continues. In the spirit of this site, good-faith intellectual curiosity, I will refrain from continuing this conversation in a manner which would reveal your nature as a human or not, and remove the hint of taste of that palpable irony from my mouth (I joke) but it wouldn’t add anything to the discussion anyway. But it would be trivial. Am I making any sense?
Show HN: Devion – AI powered release notes from your commits
by shauryaasingh | 2025-12-27 14:42:25+00:00
Hey HN! I built Devion after spending way too many Friday afternoons writing release notes instead of shipping code.

Devion connects to your GitHub repo and automatically generates professional release notes from your commits and PRs. It:

- Analyzes commit messages and PR descriptions using AI
- Groups changes into meaningful categories (features, fixes, breaking changes)
- Recognizes and highlights contributors automatically
- Generates changelogs in customizable formats
- Works with your existing git workflow - no changes needed

We're currently in demo phase and I'd love your feedback. The goal is to make release notes something that happens automatically, not something you dread doing.

Try it at https://devion.dev - would especially love to hear:
- What's missing from your ideal release notes tool?
- What would make you switch from your current process?
- Any workflow quirks we should handle?

Also working on surfacing good-first-issues for maintainers. Happy to answer any questions!

When something has an 30 TOPS NPU, what are the implications? Do NPUs like this have some common backend that ggml/llama.cpp targets? Is it proprietary and only works for some specific software? Does it have access to all the system RAM and at what bandwidth?

I know the concept has been around for a while but no idea if it actually means anything. I assume that people are targeting ones in common devices like Apple, but what about here?

the US has had lots of programs where labor can effectively be bought or contracted from prisoner sites by private companies.

I know of prison ran machine shops that were doing die-casting and tool production. I also heard of one (didn't see) that was doing basket weaving for a floral/arrangement company.

these are shallow 'social benefits'; but the companies were privately owned.

I guess the classic example is license plate pressing.. I guess that's a social good? I don't know if it goes on at all anymore.

"From GSM to LTE–Advanced Pro and 5G, An Introduction to Mobile Networks and Mobile Broadband" by Martin Sauter

This is the telecoms book I never knew I wanted. As the title suggests, it explains how the telecom world has evolved in great detail, with a particular focus on mobile technologies, although there's a chapter on SS7 and one on WiFi and Bluetooth. It stops short of packet layout descriptions, but it goes extremely deeply into the technologies it describes while still being understandable to somebody with little to no telecoms experience. This is the book that made me truly understand how that stuff really works.

Most people I know deeply hate AI. The more left their politics, the more they hate it. This issue has fully polarized for people outside tech. My intuition is that hating AI is now a permanent part of the leftist catechism.

For some, AI users are now self-allied with bigots and racists. I avoid discussing AI with anyone whose politics I don’t know anymore. If you haven’t experienced this personally, it’s hard to describe.

> Neo brokers offering highly leveraged index funds securities

These, eToro and the like, aren't "brokers" so much as online betting platforms for the stock market.

A typical broker like Interactive Brokers, Charles Schwab etc. acts as a gateway to the market, other traders act as counterparties, and is bound by strict regulation

These "neo brokers" as you call them don't. Those "securities" you're buying are offered by the broker, at a price set by the broker, the broker may be the counterparty and they can't be transferred. Just like a casino.

This is all laid out in the terms and conditions for anybody who cares to read them, e.g. [0], sections 7.1 and 17.

If you want to gamble based on stock prices using leverage, at least do it right: use derivatives. They're leveraged but thoroughly regulated and traded on central exchanges.

if a plane keeps crashing due to the same failure we don't blame the pilot

That's true, we blame the manufacturer and demand that they fix their product under threat of withdrawing the airworthiness certification. So where's the demand for Acrobat to fix its software, under pain of losing their cash cow?

Yet, people here are arguing that it is perfectly OK that professionals keep working with tools that are widely known to be inappropriate for their task. Why should we not blame the lawyers that authorized the use of inappropriate tooling for such a sensitive task as legal redaction of documents?

I’ve been using some time off to explore the space and related projects StereoCrafter and GeometryCrafter are fascinating. Applying this to video adds a temporal consistency angle that makes it way harder and compute intensive, but I’ve “spatialized” some old home videos from the Korean War and it works surprisingly well.

Ask HN: How to create a scrollable picker (like iOS/Android clock) in HTML?
by ramsicandra | 2025-12-27 14:45:46+00:00
Hi everyone,
I’m trying to build a scrollable selection UI similar to the time picker in iOS/Android clock apps, but for the web (HTML). I think it’s a great interaction pattern for touch devices.

I’ve looked at <input type="time">, which does show a similar picker on iPhone Safari, but it’s very limited: hours are capped at 24, AM/PM can’t be removed, no support for custom options or arbitrary ranges.

I managed to create a working prototype using quite a bit of CSS and JavaScript: https://ramsicandra.com/poc/scroll_select.html

I’m wondering if there’s a simpler or more native approach to achieve this, ideally without with lesser CSS/JS?
by crazygringo | 2025-12-27 14:46:02+00:00
Thank you for explaining! I didn't see this until now. I'm incredibly impressed, that's wild. It does sound like a lot of work. I see why someone like you doesn't need the updates, so thank you for that enlightenment. I think the average consumer still does, of course, but you make a great point that there are ways to protect yourself if you have the expertise and are willing to put in the work.

If your circle has any artists in it, chances are they'll also have a very negative perception, although influenced heavily by the proliferation of AI-generated art.

At least personally, I've seen basically three buckets of opinions from non-technical people on AI. There's a decent-sized group of people who loathe anything to do with it due to issues you've mentioned, the art issue I mentioned, or other specific things that overall add up to the point that they think it's a net harm to society, a decent-sized group of people who basically never think about it at all or go out of their way to use anything related to it, and then a small group of people who claim to be fully aware of the limitations and consider themselves quite rational but then will basically ask ChatGPT about literally anything and trust what it says without doing any additional research. It's the last group that I'm personally most concerned about because I've yet to find any effective way of getting them to recognize the cognitive dissonance (although sometimes at least I've been able to make enough of an impression that they stop trying to make ChatGPT a participant in every single conversation I have with them).
by xtiansimon | 2025-12-27 14:48:09+00:00
I suppose here’s the type of story where it’s all sounds good and you say show me the data. And then, if you’re inclined, run a notebook and look for comparable metrics from other cities.

https://www.nyc.gov/site/hpd/about/open-data.page

This was particularly interesting:

“Neither cooperatives nor the city typically sell flats. Mostly because …they really love recurring revenue and absolutely would hate to deal with short-term income as they are generally *non-profit institutions*.” (My emphasis)

Doesn’t seem like NYC can run their buildings at a profit, considering all the repairs that are reported as unfixed.

Agreed, at least for a likely "home use" case, such as a TV box, router, or general purpose file server or Docker host, I don't see how this board is better than something like a Beelink mini PC. The Orange Pi does not even come with a case, power supply or cooler. Contrast that with a Beelink that has a built-in power supply (no external brick) and of course a case and cooler.

There are various kinds of value and it is a mistake to confuse them or to reduce them to just one kind.

W.r.t. your imputed definition, there is a sense in which everything is irreplaceable, because the identity of two things that are otherwise entirely identical is never the same; that X is never this X.

But I was not making the claim that the value of something is its “ability be itself”. I was claiming that a thing x of kind A is more valuable as an A than a thing y of kind B as an A, where A is not B. This is trivially true.

Consider the utilitarian value of a pencil as an object for writing and consider a particle accelerator. It should be clear that the utility of a pencil as a writing instrument is greater than the utility of a particle accelerator as a writing instrument. The particle accelerator is more complex as a piece of technology, but so what? It has no value as an instrument for writing down your grocery list.

In any case, I was not proposing a comprehensive basis for a theory of value on this notion alone, so I’m not sure how you managed to selectively read that into my comment. It was only listed as one way in which one could say that a mechanical watch is more valuable than a Casio.
by cmrdporcupine | 2025-12-27 14:49:38+00:00
Can't speak to this specific NPU but these kind of accelerators are really made more for more general ML things like machine vision etc. For example while people have made the (6 TOPS) NPU in the (similar board) RK3588 work with llama.cpp it isn't super useful because of the RAM constraints. I believe it has some sort of 32-bit memory addressing limit, so you can never give it more than 3 or 4 GB for example. So for LLMs, not all that useful.

You could use pixi instead, as a much nicer/saner alternative to conda: https://pixi.sh

Though in this particular case, you don't even need conda. You just need python 3.13 and a virtual environment. If you have uv installed, then it's even easier:

git clone https://github.com/apple/ml-sharp.git
cd ml-sharp
uv sync
uv run sharp

I don't look at gambling in a religious or moral perspective at all, but rather as a predatory business. It's like any other dopamine hit, the casinos manage joy and expectation, just enough, so that people keep coming back until they are hopelessly addicted, broke, or broken.

The problem with gambling is that the house never loses, and when they are losing, they can kick you out and call you a cheater. At the very least, there needs to be severe restrictions on what casinos can do to people who are winning, and rein them in so that they don't use their money, power, influence, and heavy-handed security, in ways that are grossly unfair to the consumer. The power is too much in the hands of the casino, and really needs to swing back towards the consumer, otherwise people get taken for a ride, literally and figuratively.

Side complaint: I'm irked that the smaller surface laptop didn't continue with custom AMD chips since they were getting quite powerful in the last one.

Other complaint is that because of comments here I went looking at framework but it doesn't show what GPU comes with AMD processors so I'm going to have to not look at this on mobile.

I have a Thinkpad, Asus and surface 13" amd and none have fully scratched the itch for my go to machine. Asus is powerful enough but the build quality and durability are pure garbage.

I’m an economist and an applied mathematician and also a naturist (or nudist), whatever term you wish to use is fine by me.

Like most I’ve observed how the gender balance tends to skew male and I’ve often thought about the pros and cons of “no single male” policies that some venues enforce: on the one hand, I wish everybody to be as comfortable as possible; on the other, I risk being excluded myself (being male and currently single, but then again, I have plenty of naturist female friends whom I can attend with). I’ve also wondered if and how such a policy works.

Long story short, I got bored over Christmas and Boxing Day and was a bit restless to flex some mathematical muscle, so I ended up writing a paper based on my speculations almost by accident.

It’s totally safe for work (except the title, the only content is text, equations, and two dry diagrams produced in Mathematica).
I’d really appreciate any feedback.
And if it’s not your thing... well please believe me we’re humans too and it’s just a preference. Plus, we get to see more of our friends!

Peace.

I don't know how easy it is in Germany compared to the U S., but this is false. In the U.S., you absolute can sue (and it is extremely common) to force certain actions. See: constructive trust, mandatory injunction, prohibitive injunction, specific performance, recission, writ.

In all likelihood, you would not receive the source code in the U.S., though. If deadset against release, the outcome would likely be that the offender would be fined and injoined from any further distribution.

If I recall correctly they got scooped up by Google and their team was merged into various Google teams. I was disappointed to hear of their fizzling as well. They were just starting to dive into serious movie production light field cameras when it happened. They had an incredible tech demo on their website showcasing its power. I can't seem to locate the original but there are bits of it in the linked video.

> Cape Breton fiddler Ashley MacIsaac says he may have been defamed by Google after it recently produced an AI-generated summary falsely identifying him as a sex offender.

> The Juno Award-winning musician said he learned of the online misinformation last week after a First Nation north of Halifax confronted him with the summary and cancelled a concert planned for Dec. 19.

Cool, so we’ve reached the brain-rot stage where people are not only taking AI summaries as fact (been here for a while now, even before LLMs with Google’s quick answer stuff) but they are _citing_ them as proof. Fuck me. I know that’s a little much for HN but still, just insane, at no point did someone think to get a more primary source before canceling the show.

The complete abdication of thinking and even the most minor research is depressing. I use LLMs daily but always make sure to check the sources, verify the claims. They are great for surfacing info but that’s just the first step. I’ve lost track of how many times an LLM has confidently stated something using sources and I check the sources and they say nothing of the sort.

I think you will still pay for 3 times the tokens for a single model rather than 3 but will consolidate payment.

I was thinking to make the model choice more dynamic per agent such that you can use any model with any agent and have one single payment for all so you won’t repeat and pay for 3 or more different tools. Is that in line with what you are saying ?

Resilio Sync is an app I use to self-host files on my mesh network. I had assumed it would allow download over HTTPS when sharing files to third parties but I was wrong.
