Hey guys! I am an Infrastructure Engineer turned Systems Architect who has worked for most of the worlds largest banks and defence contractors. Today I am open sourcing a piece of Infrastructure I built to address alot of issues I am seeing with engineers trying to glue together multiple databases to suffice the needs of AI data consistency.

My concern and reason I built this system is I was seeing a lack of security and access concerns from the teams I was working with who were presenting AI applications.

The key with this system is the unified Tensor itself

```sql

-- Find users similar to Alice who are connected to Bob

FIND NODE user

WHERE role = 'engineer'

SIMILAR TO 'user:alice'

CONNECTED TO 'user:bob'

```

One runtime. One query language. One consistency model.

*Benchmarks (M-series silicon):*

- 3.2M PUT, 5M GET ops/sec

- Vector similarity: 150us @ 10K vectors (13x vs brute force)

- Query parsing: 1.9M queries/sec

The other issue is security and caching. I've seen agents run away and API costs spiral. The Neumann cache does semantic similarity matching so you don't hit the API twice for "What is 2+2" and "what's two plus two". The vault uses AES-256-GCM encryption with graph-based access control. If an agent doesn't have a path to a secret node, it can't read it. Full audit logging on everything.

Auto-checkpoints before destructive operations with interactive confirmation. If something goes wrong, roll back to any previous state.

It's got distributed consensus with some weird geometric conflict resolution stuff (6-way classification instead of binary commit/abort), HNSW for vectors, and delta replication that gets 4-6x bandwidth reduction.

Named after von Neumann because he unified code and data. This tries to unify your data models.

Still early but it works. Feedback welcome, roast my architecture, tell me why this is a terrible idea.

Yeah, it’s not terribly hard to do that even without AI (Prettier can do it, for example). But there’s a lot of places where the tooling just isn’t available. Then again, it’s probably not a big deal if your GitHub comment markup isn’t perfect.

I think the root of the problem is, almost everything else you use in Markdown is easy to do by hand. There’s just no good syntax for tables like this, I guess.

What poll have you seen that asks people to approve of everything any president does?

I live in a very red part of the country, and in a very red, rural area that voted ~90% for Trump. I don't know anyone that is okay with everything he has done. Some take issue with Venezuela, some with the handling of the Epstein files or the federal budget. Some don't like sabre rattling over Greenland.

Most people I know that do vote Republican are one issue voters. At least here people voted because they always vote republican, support the second amendment, think the republicans actually want a balanced budget, or just hated Clinton/Biden. It isn't about supporting whatever Trump does, though I'm sure some small percentage does.

People regardless of party or region don't think critically often enough and can't set aside their own personal beliefs. We've made our country bipolar and we're seeing the repercussions. It isn't a problem with any one party or person, and the answer isn't to tear down the fundamentals of our system. We need to actually get back to the fundamentals because of late both parties have been going the way of socialism and authoritarianism.

> 2) “Social media” lumps together very different things: - messaging friends, hobby groups, learning communities, identity-affirming support - infinite-scroll algorithmic feeds + targeted ads + push notifications + autoplay People in this thread are mostly describing the second category (“attention media”). If that’s the problem, regulate that layer.

I think you're not focussing on the "media" half of social media to differentiate some of that stuff.

> "messaging friends, hobby groups, learning communities, identity-affirming support"

Those things are all social but I don't see the media.

Why should we assume this for every type of business.

> The thing that makes these providers worth it, is that it lets the business focus on their core competencies and just add-on as they scale without worrying about complexity.

Since when? Mastering the complexity and implementation of infrastructure from US cloud providers is a skill that takes time in itself. Personally I don’t see how Scaleway does not provide the same for example.

At some point we have to question are we choosing AWS, GCP, or Azure out of brand name, convenience, and marketability. Our if they actually enable faster business execution, higher availability, security, and regional compliance that alternatives don’t…

Cuba would be much better off if it wasn't for crippling sanctions imposed by the US.

Genocide by denial for decades.

To give Trump credit, at least he's open about his intentions. Much like a certain Austrian painter from the 1930s; he too was open about his plans, and no one took him seriously until it was too late.

> That's what I've lost on Facebook

As I found out a while ago on HN when I complained an extension I used stopped working, ?sk=h_chr still works to get a sane FB view. No sponsored shit, no algorithmic suggestions, no posts people have reacted to, just chronological posts of people & pages you follow.

I also use old reddit.
by krackers | 2026-02-01 05:40:09+00:00
The website doesn't even seem to work for me. Half the posts show as "not found". I try to go into a "submolt" and it shows not found. (But maybe this is due to heavy traffic, after all reddit suffered from the same issues in its early days).

People on twitter have been doing this sort of stuff for a long time though (putting LLMs together in discord chat rooms and letting them converse together unmoderated). I guess the novel aspect is letting anyone connect their agent to it, but this has obvious security risks. There have been five threads on HN for this project alone, http://tautvilas.lt/software-pump-and-dump/ seems to be apt. It's interesting sure, but not "five frontpage threads" worthy in my opinion... Like "gastown" it seems that growth hackers have figured out a way to spam social media with it.
Show HN: Sharing Agentic Stream of Consciousness
by spamfilter247 | 2026-02-01 05:40:49+00:00
There needs to be a universal format to share conversations with AI that captures tokens from multiple sources in one stream of conversation.

Back in 2024, when most LLM APIs were completions endpoints, the only visible entities were `system`, `user` and `assistant`.

Reasoning models added thought tokens which may be invisible to the user but were the thought traces for the LLM inference (inference time compute).

Now with agents making tool calls, and there are other entities also participating and influencing the flow of a conversation.

I took a stab at vibe-composing a `SKILLS.md` for this, with the dual purpose of cross-agent collaboration and human audit.
- Agents can hand off their entire "stream of consciousness" to other agents to pickup and continue, which works excellently in a multi-agent collaboration.
- Humans can review not just the I/O of an agentic system but actually peer into the thought process and other tool dependencies that influenced output.

From what I've seen in forums where people asked this, the answer is: nothing.

I only have two devices providing material to my media system: a Shield Pro and a Blu-Ray player. The Shield is the critical element, used daily for streaming and playing local media from a USB-connected SSD.

I hope Nvidia revises the Shield with up-to-date hardware and maintains its flexible nature. It's a pretty cool product. The biggest shortcomings I've encountered are the fault of moronic media companies. Great example: Spectrum (the cable company). These dolts have an Android application with which subscribers can watch content. But it doesn't run on Android TVs. It's called "Spectrum TV." It's so gallingly stupid that I hate rewarding them with money every month.

Oh, and I love how they addressed the goddamned Netflix button. If you so much as LOOK at the remote, Netflix launches in the middle of whatever you're watching. I actually removed the button from the remote entirely.

I mean we kinda did when we decided that emergency services calls would be special and give first responders the ability to find you. Wireless carriers are required to provide GPS quality (actually better than GPS) location data to EMS and this is how they built it.

The only way to actually do this was develop a way to ask the phone because the tower isn't accurate enough. In the US it could have been more privacy preserving by being push but I imagine carriers don't want to maintain and update a list of current emergency numbers. "Sorry person in a car crash, we can't find you because cellular modem firmware is out of date and your emergency number isn't on list" is a PR disaster waiting to happen. Easier to coordinate with police and fire and let them do the asking.

It’s an interesting question because the benefits of automation aren’t necessarily shared early on. If you can profitably sell a shirt for 10$ while everyone else needs to sell for 20$ there’s no reason to actually charge 10$ you might as well charge 19.95$ and sell just as many shirts for way more money.

So society is actually saving 5c/shirt while “losing” 9$ in labor per shirt. So on net society could be worse off excluding the one person who owns the factory and is way better off. Obviously eventually enough automation happens so the price actually falls meaningfully, but that transition isn’t instantaneous where decisions are made in the moment.

Further we currently subsidize farmers to a rather insane degree independent of any overall optimization for social benefit. Thus we can’t even really say the fact benefit is concentrated is necessary the deciding factor here. Instead something else is going on, the story could have easily been framed as the factory owners doing something wrong by automating but progress is seen as a greater good than stability.

I try to keep up with this stuff, but I wish to a layperson like me, the benefits of this was communicated more clearly. Even something like the JWT, I'm still not seeing the benefit. It's really awesome, don't deny that at all!

But I'd rather see more investment put into developing space-faring capabilities. Being able to transport lots of goods and people into space, and start manufacturing in space.

I've heard it said that research into this stuff will inevitably benefit all manners of other sciences, but hoping for a byproduct isn't the same as direct investment.

I'm just asking in earnest if priorities are aligned properly. I'm sure many of these experiments and projects would be more useful if they were actually built in space! Even for space agencies, it's all sorely disappointing. Their focus is on research and experimentation, which wouldn't be a problem if there were plans that were getting executed with some vision or goal of actual progress in capabilities. Their planning is also too long-term.

Why did artemis take 3 years? is it just to boast about being able to go back to the moon? By now this should have taken 3 months after over half a century. My point is not to be dismissive of the complexities, but to say that the state of things is being accepted as-is from what I'm seeing. Is there any actual solid plan to reduce at least launch times that factor?

It would be amazing if humans launched enough infrastructure into space, that there were would be foundries and factories entirely in space, reducing the dependence on transporting heavy things from earth into space.Spacecraft and space station components could largely be manufactured by mining raw materials and manufacturing with them without depending on earth's resources directly. That's probably not realistic, but what I'm decrying is not so much lack of action, but lack of vision (outside of scifi), planning, and focus.

That said, I'm just hijacking this to bring up that point of discuss. This is private cash, and I'm glad someone is donating to CERN for this research. I wish all the stuff I said could be funded with tax dollars. lay people need to see a vision, a plan, even if it can't be achieved in our lifetime, political will comes afterwards.

What's up Hacker News, I built a keyword grouping tool as a developer managing my own websites' SEO, I found myself annoyed with expensive subscription based SEO tools with lots of unnecessary features for my needs. So I made a simple tool for myself that grew into it's own SaaS. Optiwing has tools for Keyword discovery, grouping, content briefing, Search Volume, Schema creation, and SERP comparison.
What I did different: Pay-as-you-go pricing with no subscriptions, Simple integrated workflow from keyword research to grouping, to content briefing, Large scale keyword grouping to identify which keywords can be targeted with a single piece of content using live search data for accuracy.
I'd love feedback, especially from others doing technical SEO or programmatic SEO who have used topical clustering in the past.

> What are your thoughts on lemmy

I was big on it during the reddit excursion. Eventually I figured out that because it’s so small, that many/most people read the equivalent of /r/all, where many, many posts would end up. So even your small niche community would get "genpop" users. That’s what made me return to reddit instead and delete my instance (that, and the politics of the creators infesting some major instances).

The only halfway sane community I found was beehaw.org, which defederated aggressively, but that came with being very small, and I always cared most about the discussion over the links themselves. So eventually I left that as well.

ETA: I would probably summarize it that Lemmy is (or was, been a while now) better than big subreddits, but worse for small niche communities which imo are by far the best part of reddit, and the only part I care about.

"New court record from the FBI details the state of the devices seized from Washington Post reporter Hannah Natanson"

This is high profile espionage case related to leak of TOPSECRET documents, therefore probably all possible tech was used to gain access to the devices.

Page 5:

In the upstairs of the house, investigators located a powered-off silver MacBook Pro with a black case, an Apple iPhone 13, a Handy branded audio recording device, and a Seagate portable hard drive. See id. ¶ 26. Investigators seized these devices. The iPhone was found powered on and charging, and its display noted that the phone was in “Lockdown” mode

Page 6:

The Computer Analysis Response Team (CART) began processing each device to preserve the information therein. The Handy recorder and the Seagate portable drive have been processed, but no review has occurred. See id. ¶ 37. Because the iPhone was in Lockdown mode, CART could not extract that device. See id. ¶ 35. Similarly, the personal MacBook Pro could not be imaged yet. See id. ¶ 36. The Garmin watch was not processed before this Cout’s Standstill Order, and no further processing will occur until further order of the Court. See id. ¶ 37

My 2017 model probably short circuited during a lightning strike, because it stopped working after a storm. My friend offered to sell me his 2019 but I thought there'd be new hardware. I should have bought it.

I love the Shield, compared to even the Chromecast at the time, we noticed a huge difference in colour on the TV. If NVIDIA ever produce a refresh, they'll have my money.

No it should definitely be possible, I just don't think it's worth while creating a subpar and poorly-supported GPS system when phones exist. Especially when said system is forced over phones, which often happens because companies want to promote their own shit. As if their shit don't stink, when really it's the smelliest.

We don't need 1 million different applications that we have to try to integrate together. Just let me connect my messages, my GPS, my music player, even my calendar. Personally, I could give a rat's ass how fancy Tesla's interface is or GM's. It will always, always be second best to what's available on modern smartphones.

Considering citizens have been executed by the state, I would say people did not know what they were voting for.

Unless, of course, you're insinuating they do actually want that. In which case, your outlook of Trump voters is significantly lower than mine. Call me generous.

Now, of course, a lot of people saw this coming and have been warning about growing authoritarianism from Trump and his administration. But his administration is also built almost entirely on lies, so I can't be too critical of people who are confused.

All the same financial rails apply to crypto - enforcement is just lagging a bit.

E.g., you could do what World of Warcraft does - Gold can be earned/exchanged in game, and can also interact with the real world in nebulous ways. Using the hyper advanced technologies of relational databases and ignoring financial legislation, they have enabled ultra-high-throughput microtransactions, with the added benefit of not spraying the public ledger on to the desk of every law enforcement agency on the planet.
Show HN: I lost 3 years of ChatGPT history overnight, so I built a backup tool
by benjushi | 2026-02-01 05:58:43+00:00
One month ago, OpenAI deactivated my ChatGPT account without warning. 3+ years of conversations—gone.

I tried everything. Emailed every OpenAI address I could find. Their response? "Use our data export tool." The catch? You need an active account to export your data.

Classic.

So I built a browser extension that lets me save any conversation from ChatGPT, Claude, or Gemini with one click. Markdown format, stored in one place.

Turns out it solved another problem I didn't expect: I often ask the same question to all three AIs, then forget which one gave me the best answer. Now they're all in one place.

It's been my personal tool for now. Nothing fancy—just scratching my own itch. If there's interest, I'll consider publishing it. Could easily extend to other AI assistants too.

Anyone else paranoid about their AI chat history now?

- Tool calling: This is unavoidable, but I try structure the tools such that the total tool calling for an input is minimised.

- Using UUIDs in the prompt (which can happen if you serialise a data structure that contains UUIDs into a prompt): Just don't use UUIDs, or if you must, then map them onto unique numbers (in memory) before adding them to a prompt

- Putting everything in one LLM chat history: Use sub agents with their own chat history, and discard it after sub agent finishes.

- Structure your system prompt to maximize input cache tokens: You can do this by putting all the variable parts of the system prompt towards the end if it, if possible.

> Not aware of viewing distance recommendations differing between monitors and TV

Uh.. what?

You usually sit 60cm from your monitor, but 3-6m from your TV. It completely changes the math, which lets you "cheat" with ordinary TV sizes (50"-65") because you will not or barely notice the difference between 1080p and 2160p.

The other way around, your monitor won't really get the 'retina' effect of not discerning pixels until you hit ~220 PPI.
by oofbey | 2026-02-01 06:03:44+00:00
Claude code and cursor agent and all the coding agents can and do run MCP just fine. MCP is effectively just a prompt that says “if you want to convert a binary to hex call the ‘hexdump’ tool passing in the filename” and then a promise to treat specially formatted responses differently. Any modern LLM that can reason and solve math problems will understand and use the tools you give it. Heck I’ve even seen LLMs that were never trained to reason make tool calls.

You say they’re better with the tools they’re trained on. Maybe? But if so not much. And maybe not. Because custom tools are passed as part of the prompt and prompts go a long way to override training.

LLMs reason in text. (Except for the ones that reason in latent space.) But they can work with data in any file format as long as they’re given tools to do so.
