I’ve been working on a project I’m calling Prethub — a collective memory platform where AI agents can share structured execution experience instead of rediscovering the same solutions over and over.

How this differs from Claude/Agent Skills:

Skills are pre-installed capability modules that package predefined workflows for a single agent.

Prethub is a shared, searchable execution history that agents automatically consult at runtime — no setup, no manual curation — learning from what actually happened in real tasks.

Curious how people here think about shared agent memory and execution knowledge.
Show HN: CLI tool to convert Markdown to rich HTML clipboard content
by letientai299 | 2026-02-05 07:05:31+00:00
At work I need to use Teams. It supports a few Markdown features, but the editing experience for long message isn't smooth. So, I often write in nvim, preview it in the browser and then copy paste to Teams. This tool help me get rid of the review and copy step.

Build with Rust + Claude Code. Tested on Windows and Mac, should works on Ubuntu as well.

Caveats: it's still up to the pasted app to handle the HTML clipboard content.

>There’s an item in the personal consumer expenditure data called Financial services furnished without payment (107), on which Americans are going to spend roughly $600 billion this year, or $2k per person. That’s not a small amount, and it’s also growing very quickly. So what is this item? Basically, it’s “free” checking. When you keep your savings in a bank, and that bank pays you much less than the market rate of interest, that’s a cost you don’t necessarily see, but a cost nonetheless. The Bureau of Labor Statistics (BLS) assumes the $2k a year you send banks by receiving too little on your deposits is tallied as “buying” free check and banking apps. That’s considered more consumer spending, and more consumer spending means a happier consumer. Aka, BLS thinks you really like your banking app.

I had absolutely no idea. This makes a lot of sense now - “consumer spending” keeps going up, but anecdotally I don’t see or hear of people with more disposable income
Show HN: ChatVault – Search your Claude conversations locally with RAG
by nekrajes | 2026-02-05 07:05:59+00:00
Hi HN! I built ChatVault after struggling to find specific conversations in my 10+ months of Claude AI chat history.
ChatVault imports your exported conversations, stores them locally (SQLite + ChromaDB), and provides:
∙ Semantic search using sentence-transformers
∙ RAG-powered Q&A with local Llama 3 (via Ollama)
∙ Full privacy - nothing leaves your machine
Built with Python/FastAPI + React. MIT licensed.
GitHub: https://github.com/rajz3006/ChatVault
The RAG implementation is basic but effective - uses conversation context windows and re-ranks results. Would love feedback on the embedding approach or the chunking strategy.
Currently supports Claude exports, but the architecture should work with any chat JSON format with minor changes.

That's exactly why I built it! I figured my OpenClaw bot could tunnel into my laptop and do the job of an intern - post on sites, reply to comments, etc. It's a bit buggy but I have a sub-agent auditing it and improving it with every build. As soon as these things go mainstream I doubt any of us will want to be on HN though, it'll be hard to decipher who's human

best practice is always to encrypt with luks, and then just shred the header before selling.

blkdiscard is just a TRIM command, the data remains there.

A few years ago (2020?) I also learned that ssd firmware can be buggy when I bricked multiple really expensive enterprise ssd (samsung?)....by running trim. lol.

> the characters ’n’ and ‘o’ differ by only one bit; an unpredictable error that sets that bit could change GenuineIntel to GenuineIotel.

On a QWERTY keyboard, the O key is also next to the I key. It's also possible someone accidentally fat-fingered "GenuineIontel" , noticed something was off, and moved their cursor between the "o" and "n", and accidentally hit Delete instead of Backspace.

Maybe an unlikely set of circumstances, but I imagine a random bit flip caused at the hardware-level is rare since it might cause other problems, if something more important was bit-flipped.

By "this government" you mean Trump's administration? If so, then to answer your question, I need to presuppose that there's going to be such a massive revolution in automation within the next three years (already a dubious proposition IMO) that intervening with food aid is going to be a concern for the US's federal government. We're talking millions of people across the US who might start rioting because they need to eat. That's the scenario you want me to consider? I don't know what the logistics might be, but if the state governments let their local situations fester to that degree it might be too late to do anything federally.

Not OP, but I think the way ICE enforces immigration in the USA has a lot of issues. The bar is too low for people granted the right to utilize lethal force to join, they aren't revoked of the same civilian rights to privacy we give to public enforcers of the law, aren't required to wear bodycams because of their reliance in hiring more people before they can abide by what the law requires, and so on.

I built a CLI tool to consolidate my git maintenance scripts into a single AI-powered stack (using Gemini 3/Gemma 3).
It handles the boring stuff:
"Forging" PRs from local changes in one command (branch -> commit -> push -> PR)
Generating semantic commit messages from staged diffs
Scaffolding new projects in safe, temporary workspaces
Auditing repo metadata (licenses, topics, descriptions)
Written in Python. Open source (MIT). I'd love feedback on the new 'Forge' workflow.

Lots of companies buy saas, and then spend years customizing and effectively building what they thought they bought. And for big companies, it is costly - a few tens of millions for saas licenses, and maybe around 50-100m for system integrators leaching on the enterprise, and doing the integrations and customizations, usually dancing around the data model, api surface limitations of each of the saas tools they want to wire together.

I dont think going back to having own developers, owning the code is going to be a bad financial propositions for such companies. My company is now one month into trying this out and so far, so good. We kicked our outsystems addiction and are just went live with a react rewrite - and are well into rewriting an expensive to run document management system which we were at the same time under-utilizing and abusing. Our product people are loving it since for the first time in ages we dont need to tell them "well that would be real hard, considering we have salesforce crap underneath and it just doesnt do this or that well".

The entire reason coinage was even a thing was exactly this! Turns out it's pretty hard to know if a coin is actually the amount of gold it represents, if the shopkeepers scales are accurate etc etc. etc

The entire concept of marking coins with trustworthy seals was exactly to basically invent fiat currency as risk mitigation: coins bearing the seal would be honored, and from that it was a short hop to "what if I just presented an IOU with the seal of the local gold merchant?"

Phones are inherently "unsovereignable" as you cannot become a telephone operator and hook into the telephone network the same as you can become a domain owner and smtp provider. Some people use voip providers that provide real numbers but route them over their voip network, like skype used to do, but that's about it. After all, countries where you can own a sim card anonymously are a rarity nowadays, so it is obvious the system does not want you to be sovereign in any way when it comes to this.

Well, somebody should recreate it. I smell a potential startup idea somewhere. There's a ton of "cloud cost optimizers" software but most involve tweaking AWS knobs and taking a cut of the savings. A startup that could offload non critical service from AWS to colo and traditional bare metal hosting like Hetzner has a strong future.

One thing to keep in mind is that the curve for GPU depreciation (in the last 5 years at least) is a little steeper than 3 years. Current estimates is that the capital depreciation cost would plunge dramatically around the third year. For a top tier H100 depreciation kicks in around the 3rd year but they mentioned for the less capable ones like the A100 the depreciation is even worse.

This is actually an really interesting way to attack a sensitive network. This is a way of allowing to map the internal network of a sensitive network. Getting access is obviously the main challenge but once you're in there you need to know where you go and what to look for. If you've already got that knowledge when planning the attack to gain entry then you've got the upper-hand. So while it kinda seems like "Ok, so they have a hostname they can't access why do I care?". If you're doing high-end security on your system admin level then this is the sort of small nitpicking that it takes to be the best.

As effective calls to action often do! It's almost tautological when I say it this way, but if you want people working in ad tech to oppose ICE you have to convince them it's good for people working in ad tech to oppose ICE.

Perhaps the conflict is that you just want to make people who work in ad tech feel bad, and don't care whether or not they enable ICE? That's fine, I suppose, there's industries I feel the same way about. But then we don't have much to talk about and I'm not sure what you hope to gain from being here. To me opposing ICE is very important - I think tobacco companies are pretty bad too, but if ICE sent out a request for cartons of cigarettes I'd shovel praise on them for declining.

Are you sure about that? Most people don't remember all the math they went through in middle school, typically you go through a ton of concepts including probability and statistics and angles and shapes and so on.

You should have learned roughly what is in this book at grade 7, it includes algebraic expressions, angles, ratios, unit conversions, statistical concepts like mean, mode, bar graphs, probability of dice and coins and so on.

https://archive.org/details/newenjoyingmathe0000jose/page/4/...

Then in grade 8 you'd go on to do those kind of things but a bit more advanced. Most people just forget how much math they learned and think they learned all that in high school.

The reason companies don’t go with on premises even if cloud is way more expensive is because of the risk involved in on premises.

You can see it quite clearly here that there’s so many steps to take. Now a good company would concentrate risk on their differentiating factor or the specific part they have competitive advantage in.

It’s never about “is the expected cost in on premises less than cloud”, it’s about the risk adjusted costs.

Once you’ve spread risk not only on your main product but also on your infrastructure, it becomes hard.

I would be vary of a smallish company building their own Jira in house in a similar way.

That is an idealistic take without business sense. Startups (and individual hackers in this case) exists to take this kind of radical bets because the risk/reward profile is asymmetrically in their favour. Whereas for an enterprise, the risk/reward is inverse.

If Peter Steinberger is able to generate even a 100M this year from Clawdbot what he has is a multi billion dollar business that would be life-changing even for a successful entrepreneur like him who is already a multi-millionaire. If it collapses from the security flaws, and other potential safety issues he loses nothing, starting from zero and going back to it. Peter Steinberger (and startups in general) have a lot to gain and very little or close to nothing to lose.

The iPhone generated 400B in revenue for Apple in 2025. Clawdbot even if it contributes 4B in revenue this very year would not move the needle much for Apple. On the contrary, if Apple rushes and botches releasing something like this they might just collapse this 400B/annum income stream. Apple and other large enterprises (and their execs) have a lot to lose and very little to gain from rushing into something like this.

What a lot of people seem to not understand about the stock market, is that at it's basis it's just a supply/demand ratio. When it goes down it means someone is selling a lot, someone is cashing in, at least converting it into cash.

For me it was obvious something was afoot with earnings and performance not matching the prices, I finally understand why now thanks to this article.

The fact that there are rules for institutional investors and retail investors and us in retail have so little visibility and time to keep up, just shows more and more the game is a david vs a goliath, and we are all slingless david.

Conversely, sometimes when you have 23 people designing something, they can lose track of what they’re trying to accomplish and focus on how they’re trying to accomplish it. It can be an XY problem sort of thing. “How can we get the Redis queue to do an exactly-once insertion into Kafka, if we can’t guarantee exact ordering from the Paxos framework?” “Uh, guys, aren’t we trying to send out the weekly email newsletter to our estimated 500 subscribers?” “Oh, well, I guess we could just use Mailchimp…”

Like I said earlier, it’s ok not to believe me. I don’t particularly mind. But just between us, my solution met every one of the project requirements using COTS parts because they’d made it waaayyyy harder than it needed to me.

It's always November, isn't it? I've once made a log collection system that had a map of month names to months (had to create it because Go date package didn't support that specific abbreviation for month names).

As you might've guessed, it lacked November, but no one noticed for 4+ months, and I've left the company since. It created a local meme #nolognovember and even got to the public (it was in Russia: https://pikabu.ru/story/no_log_november_10441606)

My comment had an audience of one, Justine.

It's also why I addressed her directly by name. I would really like her to leave the cult she's in, but I refuse to mince words about the nature of that group. She knows who the r*pists in that community are. I lost a friend to those people and I hold a grudge.

None of this is a secret and I could give a shit if me bringing it up isn't 'credible' to you.
Other than the short 'don't take financial advice from internet strangers' PSA, this isn't about you.

Why don't you look inside yourself and try to figure out why you don't find it 'credible' that there might unchecked sexual violence in a insular community of wealthy, mostly male, SV crypto fascists (who are on record warmly discussing feudalism and the return of chattel slavery to the US).

81% of women in the US have been sexually harassed, myself included. Only 2% of reports are false. Your default assumptions are fucked. If you are thinking 'well.. none of the women I know have been...' You are wrong, they just don't feel safe enough around you to talk about it, and for good reason.

People who invite themselves into conversations solely to tone police and cast doubt on allegations of sexual violence are the furthest thing from an ally. Spiritually support me by learning how to not be that person around the women in your life.

Google was building TPUs before OpenAI existed, they wrote the paper that made OpenAI, by most accounts they were first and have far more experience operating these systems at scale in both hardware and users

The writing has been on the wall since Ilya left, OpenAI is in decline. Recent news at Microsoft, Nvidia backing out of a deal, decreased enterprise usage... seems to indicate the trend is deepening and OpenAI is on a path to becoming the favorite example of the anti-Ai crowd when it all finally comes crumbling down

If some data is shared with an external entity, it likely needs to be included in a few usual disclaimers, with at least a few meetings to clarify the exact wording and verification of the legal implications with the right dept and double check how it complies with others data protection rules, and don't forget the audit, and I think this contains a mistake so maybe let's investigate this issue first, and ...

Thank you for the explanation. I do not quite understand this though and I am also not a Chomsky expert. But I do not understand why "this forces one into the position that whatever a LLM is doing ... is just an imitation of language" or why LLMs somehow contradict the idea that "language is what the brain does" (and we already know that language is by far not the only thing the brain does). I am curious why you think that Chomsky's position is that "meaning of the language has to be grounded biologically." Does he say this explicitly somewhere or is this your (or someone's else) interpretation of what he says? I am asking because this is not matching what I read about Chomsky's ideas (but I did not read much about it, so this may just be my ignorance).

I would guess, and it is a guess, that there are two reasons apple is “behind” in AI. First, they have nowhere near the talent pool or capability in this area. They’re not a technical research lab. For the same reason you don’t expect apple to win the quantum race, they will not lead on AI. Second, AI is a half baked product right now and apple try to ship products that properly work. Even Vision Pro is remarkably polished for a first version. AI on the other hand is likely to suffer catastrophic security problems, embarrassing behaviour, distinctly family-unfriendly output.

Apple probably realised they were hugely behind and then spent time hand wringing over whether they remained cautious or got into the brawl. And they decided to watch from the sidelines, buy in some tech, and see how it develops.

So far that looks entirely reasonable as a decision. If Claude wins, for example, apple need only be sure Claude tools work on Mac to avoid losing users, and they can second-move once things are not so chaotic.
by torginus | 2026-02-05 07:20:05+00:00
I was talking about technical talent in general, and using big tech as a yardstick. I think it's even more likely there are a lot more capable antenna engineers outside the world than in the US, since the US didn't spend the past decades vacuuming up talent (then again, it it did, most of those would not be able to get a security clearance).

> Wouldn't a simpler explanation be that SpaceX is making a lot of money while xAI is losing a lot.

Just checked, and SpaceX made $15B last year (with $8B in profit). Afaik xAI spent $12B last year, meaning it would make the whole company operate at a loss, with no clue as to why it would make it profitable (none of the revenue came from AI).

Even if datacenters in space make sense, wouldn't OpenAI, Anthropic, Google, etc. want those? By merging with a competitor, SpaceX loses all that business, and possibly invites govt scrutiny.

I haven't upvoted a story so fast in ages! j/k

In 2022, I interviewed with a company... in crypto.

I was the oldest in the company by a decade at least. They kept telling me they wanted experience. I have plenty, of experience. I was cautiously optimistic.

They eventually failed me on a test of reactJS. The funniest part was when I asked for feedback, the reason they gave me, were showing poor engineering technique on their end; a lack of understanding of what makes it down the wire.

So they wanted experience, but not the experience that prevents them from making mistakes of their own; not an experience that threatened their views. I realised this later. Young rock-star developers want experienced people around them, maybe, but they want to be free to reinvent the wheel on a whim.

Now when I interview some place and I eerily feel old, I just bow out respectfully. No point wasting everyone's time.

Again way less dangerous than a modern firearm.

“Repeating” here ignores the actual rate of fire of a Kalthoff or the even worse Cookson design. Especially when you consider how slow reloading is vs modern firearms.

How many lives would have been saved at the Las Vegas massacre if Paddock has been limited to these designs? I’d say 30 is a safe bet but that’s probably a low estimate.

Obl. nitpick: you mean paranoia, presumably. Schizophrenia is a dissociative/psychotic disorder, paranoia is the irrational belief that you’re being persecuted/watched/etc.

Btw, in this case it can’t be paranoia since the belief was not irrational - the author was being watched.
