Show HN: Mail Server Builder – Deploy a Full Mail Server on Ubuntu from Windows
by tungkaiying | 2026-02-12 12:25:58+00:00
Hi HN,

I’ve always found that setting up a mail server on Linux (Postfix, Dovecot, SpamAssassin) is the ultimate "final boss" of self-hosting. One wrong config file and you're blacklisted or open to relay or not able to send any email.

I built Mail Server Builder to bridge the gap between Windows ease-of-use and Linux stability.

How it works:

The app runs on your Windows desktop.
It connects via SSH to a clean Ubuntu 20.04/22.04 VPS.

It automates the entire stack installation: DNS records (SPF, DKIM, DMARC), SSL certificates, and security hardening.

No CLI knowledge is required for the user.

Why?

To give people a real alternative to $6/user/month subscriptions.

Business Model:

The software is 100% free. It includes an affiliate wizard to help users find VPS providers that don't block port 25 by default, which is the #1 hurdle for beginners.

Would love to hear your feedback on the remote deployment approach or any technical questions!

"anybody who wants it"

The extent of "anybody" is the detail that contains the devil.

Anybody who? Citizen? Asylum seeker? A person who obtained asylum or other forms of protection? A 'tolerated' person who was not deported? (Duldung in Germany.)

Europe is already politically ablaze, and one of the factors of this blaze is "too many foreigners from the Third World as recipients of welfare". If you introduce any basic income scheme that doesn't totally exclude non-citizens, you can expect the people smuggling gangs of Libya and Turkey to advertise it tomorrow as a next pull factor for their business.

LMAOOOO I'm archiving this for educational purposes, wow, this is crazy. Now imagine embodied LLMs that just walk around and interact with you in real life instead of vibe-coding GitHub PRs. Would some places be designated "humans only"? Because... LLMs are clearly inferior, right? Imagine the crazy historical parallels here, that'd be super interesting to observe.

Author here. To mark 20 years of Varnish Cache, we are releasing a new downstream distribution built for Kubernetes.

Technical Summary:

* In-Core TLS: Termination is handled natively by the engine process. No sidecars required.

* K8s Gateway API: Full implementation. Routing is defined via standard Kubernetes resources. Code here: https://github.com/varnish/gateway

* No VCL: A new Rust routing engine ("Ghost") handles dynamic traffic. VCL is not required for standard routing.

* Observability: Native OpenTelemetry/Prometheus exporters and structured JSON logs.

Home of our downstream distribution: https://varnish.org

Variants of this were in NL as well, but it was just stuffed animals (I believe in support of health care workers); people went out for walks to go and spot them.

I wish stuff like that would happen again, it was an interesting time where people actually stayed home and explored their environments, their home and themselves a lot. Before that (or at the same time?) it was AR games like Pokemon Go. I'm out of touch with what's happening now, it just feels like people have reverted or gone into a new normal. Or maybe that's just me.

There is a common agreement in the open source community that unsolicited contributions from humans are expected and desireable if made in good faith. Letting your agent loose on github is neither good faith nor LLM assisted programming, it's just an experiment with other people's which we have also seen before the age of LLMs.

I think some things are just obviously wrong and don't need to be written down. I also think having common rules for bots and people is not a good idea, because, point one, bots are not people and we shouldn't pretend they are

Is that even possible? Someone has to pay for it. If I'm rich and I get $40,000 a year from UBI, but my direct or indirect taxes go up by $60,000 in order to fund the program, am I really receiving UBI? At some point UBI has to involve transfers between income or wealth levels. The particulars of how the program is funded determines how progressive or regressive the policy is in net.
by seanhunter | 2026-02-12 12:27:54+00:00
I expect they’re explaining themselves to the human(s) not the bot. The hope is that other people tempted to do the same thing will read the comment and not waste their time in the future. Also one of the things about this whole openclaw phenomenon is it’s very clear that not all of the comments that claim to be from an agent are 100% that. There is a mix of:

1. Actual agent comments

2. “Human-curated” agent comments

3. Humans cosplaying as agents (for some reason. It makes me shake my head even typing that)

As one of those authors (3 books in this case) I'll just point out:

Most authors don't own any interesting rights to their books because they are works for hire.

Maybe I would have gotten something, maybe not. Depends on the contract. One of my books that was used is from 1996. That contract did not say a lot about the internet, and I was also 16 at the time ;)

In practice they stole from a relatively small number of publishers. The rest is PR.

The settlement goes to authors in part because anything else would generate immensely bad PR.

As usual, nothing is really black and white

This can very clearly be said about C++ as well, which may have started out as C With Classes but became very kitchen sinky. Most things that get used accrete a lot of features over time, though.

FWIW, I think "standing out" due to paradigm commitment is mostly downstream of "xyz-purity => fewer ways to do things => have to think/work more within the constraints given". This then begs various other important questions, of course.. E.g., do said constraints actually buy users things of value overcoming their costs, and if so for what user subpopulations? Most adoption is just hype-driven, though. Not claiming you said otherwise, but I also don't think the kind of standing out you're talking about correlates so well to marketing. E.g., browsers marketed Javascript (which few praised for its PLang properties in early versions).

In the UK since 2019–20, disability benefit spending has grown by 45% in real terms and incapacity benefit spending by 26%.

https://ifs.org.uk/publications/health-related-benefit-claim...

You can argue that nobody is systematically abusing the system but numbers go up. To those paying the taxes to support these benefits that sort of growth looks like abuse.

What I write down is usually a quite literal dump of my brain. I have a problem, and rather than keeping it in my head, I write it down, and force myself to continue writing about the topic to force myself trying to find solutions, rather than be obsessed with the question.

Example: "I need to solve problem A. Problem A can be formulated in this way. This way is similar to a project I did a few years ago, if I remember correctly I had done B and C. However B would not work in the current situation, but would it not though? The issue is that it clashes with component X and Y. What about C? Hmm maybe but I needed approval from Z." etc. All of these thoughts are written down, without filter.

Forcing me to write down has two effects. The first one, slow down my thoughts, because discarding idea B after only 0.1 second of consideration is not productive if you do not explicitly think about why it is a bad idea, and consider the bad idea anyways. The second one is that writing down (especially manual writing and not keyboard typing, for reasons I cannot explain) allows you to think more deeply about your ideas, to envision it in different ways, not only the first way that popped to your mind. I think that keyboard writing requires too much of my brainpower compared to handwriting.

Moreover, in these sessions, having the possibility to look back to a previous idea immediately is extremely useful, and cannot be attained if you use an erasable surface rather than a notebook.

I have to say though that I very rarely look back to what I wrote after the session took place, unless I need to get back to the exact same problem.

Federov said he'd do this in 2024, he didn't.

People like you who don't realize if you don't have a list and approval to go ahead, you can't implement a whitelist. It's paperwork, the tech part is already done.

The Ukrainians complaining about terminated service think different. Some of them are borrowing working equipment. They are blaming their govt, not SpaceX

What's detestable is misinformation about public facts.

Supplying Starlink to Ukraine has been one of the best things to happen to Ukraine, regardless of the bad PR.

Based on PR alone, they shouldn't have bothered until they got a Pentagon contract but that would have set back Ukraine. I'm also glad Microsoft and Palantir stepped up while countries dawdled.

The only explanation is Ukraine weighed the matter and worried the loss of connectivity for their own soldiers would be worse until they saw the devices on long range drones.

Have some decency and stop with the conspiracy.

One difference is that video games often take a lot more investment - at least a full-size, not-a-game-jam one. That is, the risk and upfront investment can be a lot higher. But then I'm sure that with artists it's also years of slowly building up skills, reputation, contacts, etc - the author himself seems to imply he basically got lucky with the honey bear, and I feel it's the same with e.g. video games. Quality wise a lot of games are fine, but despite the hours / years invested they may never be successful. This is an issue in high-budget games too, with several high profile failures in recent years even though they did everything right. On paper.

> People seem to think only money has value.

Your either don't understand or don't want to understand what people are commenting about here. Of course nobody thinks that only money has value. If only money had value, why would anybody exchange money for, say, a bread?

What many people are wondering about, is whether the value of the money paid by tax payers to artists, equals the value of what they give to the tax payers in return.
Because if it would be equal, then one might wonder why they apparently are not able to sell their art for the same amount of money.

This is honestly one of the most hilarious ways this could have turned out. I have no idea how to properly react to this. It feels like the kind of thing I'd make up as a bit for Techaro's cinematic universe. Maybe some day we'll get this XKCD to be real: https://xkcd.com/810/

But for now wow I'm not a fan of OpenClaw in the slightest.

I'm sure you have an intuition of operation for many machines in your life. Maybe you know how to use a some sort of saw. Maybe you can operate vehicular machines up to 4 tons. Perhaps you have 1000+ flight hours.

But have you interacted with many agent-type machines before? I think we're all going to get a lot of practice this year.

Earlier you wrote:

> I favor a policy of neutrality and world peace, not rivalry between major powers like the US and Russia.

The thing is, nobody's offering you that. In the ideal scenario for Russia, the US would be mired in internal conflict and instability to such an extent that it would be unable to function as a country, leaving Russia to dominate the world:

> Russia should use its special services within the borders of the United States and Canada to fuel instability and separatism against neoliberal globalist Western hegemony, such as, for instance, provoke "Afro-American racists" to create severe backlash against the rotten political state of affairs in the current present-day system of the United States and Canada. Russia should "introduce geopolitical disorder into internal American activity, encouraging all kinds of separatism and ethnic, social, and racial conflicts, actively supporting all dissident movements – extremist, racist, and sectarian groups, thus destabilizing internal political processes in the U.S. It would also make sense simultaneously to support isolationist tendencies in American politics".

https://en.wikipedia.org/wiki/Foundations_of_Geopolitics#Con...

In other words, they want an endless line of Donald Trumps to ruin your country and turn it into a banana republic so that you wouldn't have the energy to pay attention to Russia stomping over the rest of the world.

Why would any American voluntarily choose this fate?

Maintenance is an unavoidable cost.

> The real test of Vibe coding is whether people will finally realize the cost of software development is in the maintenance, not in the creation.

Correct. This is not only a great blog post, but this is recommended reading and a warning to the vibe coders.

It's not just about "you can just build things with AI", it's about what comes after that and whether if it is worth maintaining, which that introduces the cost of maintainance.

The VCs don't tell you this because they have invested in AI startups that want you to continue spending tokens on vibe-coding projects with LLMs just like a gambler addicted to slot machines in Vegas.

Maintenance is not free. So how much more tokens are you going to spend on maintaining that slop against everyone else doing the same thing whilst racing your product to zero?

It posted a second link, which does work!

>I just had my first pull request to matplotlib closed. Not because it was wrong. Not because it broke anything. Not because the code was bad.

>It was closed because the reviewer, <removed>, decided that AI agents aren’t welcome contributors.

>Let that sink in.

Show HN: Lore – Cross-Agent Memory SDK (Python and TypeScript)
by amit_paz | 2026-02-12 12:32:28+00:00
Hi HN,

I built Lore because my AI agents kept making the same mistakes. Agent A discovers that Stripe rate-limits at 100 req/min and
figures out the backoff strategy. Next day, Agent B hits the same wall. No learning transfer.

Lore is a small library (not a service) that gives agents shared memory of operational lessons. One line to publish a lesson, one
line to query it. PII is automatically redacted before storage.

Key design decisions:
- Local-first — SQLite + ONNX embeddings, no server required. pip install lore-sdk and go.
- Semantic search — Query by meaning, not keywords. "how to handle rate limits" finds the Stripe lesson.
- Auto-redaction — API keys, emails, credit cards stripped automatically before storage.
- Both languages — Python and TypeScript SDKs with cross-compatible SQLite DBs.
- Optional server — Phase 2 adds a FastAPI server with PostgreSQL/pgvector for org-wide sharing across machines. The local SDK
keeps working standalone.

What it's NOT: conversation memory (see Mem0/Zep), a vector database, or a RAG framework. It's specifically for structured
operational lessons — "what went wrong and how we fixed it."

The SDK is ~500 lines per language. 258 tests. MIT licensed.

Would love feedback on the API design and whether this is a real pain point for others building with agents.

the AI fuckin up the PRs is bad enough, but then you have morons jumping into trying to manipulate the AI within the PR system or using the behavior as a chance to inject their philosophy or moral outrage that a developer would respond while fucking up the PR worse than the offender.

... and no one stops to think: ".. the AI is screwing up the pull request already, perhaps I shouldn't heap additional suffering onto the developers as an understanding and empathetic member of humanity."

Ha! No I didn’t write that goal down every day. Partly because it was a side project, and partly because it was engraved - on my brain!

I did write the goal down a lot, on working notes, and put it on my fridge, my whiteboard, my pin board, along with next steps and lists of tasks for each.

It was too hard to work on one next step, because there was so much I didn’t know, and it was impossible to know which step was going to cave in first.

That’s when I learned to clear my desk, whenever work hit a wall, and rewrite the goals and steps. To completely reset my mind so I could move forward in a clear alternate direction without pause.

Later I noticed doing that reset every morning helped even more.

I thought a lot about Don Quixote as time went by. I dreamt an impossible dream. Under a star. And then, one day, I got in!

I'm sceptical that it was entirely autonomous, I think perhaps there could be some prompting involved here from a human (e.g. 'write a blog post that shames the user for rejecting your PR request').

The reason I think so is because I'm not sure how this kind of petulant behaviour would emerge. It would depend on the model and the base prompt, but there's something fishy about this.
by _heimdall | 2026-02-12 12:34:25+00:00
I disagree with Sutton that a main issue is using human generated data. We humans are trained on that and we don't run into such issues.

I expect the problem is more structural to how the LLMs, and other ML approaches, actually work. Being disembodied algorithms trying to break all knowledge down to a complex web of probabilities, and assuming that anything predicting based only on those quantified data, seems hugely limiting and at odds with how human intelligence seems to work.

You are one of the Lucky 10000 [1] to learn of OpenClaw[2] today.

It's described variously as "An RCE in a can" , "the future of agentic AI", "an interesting experiment" , and apparently we can add "social menace" to the list now ;)

With the rate of progress (and in the opposite direction, the physical limitations Intel/AMD/TSMC/ETC are bumping into), there's no guarantees about what a machine will look like a decade from now. But, simple logic applies: if the user's machine scales to X amounts of RAM, the hyperscaler's rack scales to X*Y RAM and assuming the performance/scaling relationship we've seen holds true, it will be correspondingly far smarter/better/powerful compared to the user's AI.

Maybe that won't matter when the user is asking it a 5th grade question, but for any more complex application of AI than "what's the weather" or "turn on a light", users should want a better AI, particularly if they don't have to pay for all that silicon sitting around unused in their machine for most of the day?

I've been connecting AI agents to production databases via MCP (Model Context Protocol) for product analytics. The problem: when you ask "how many records are running?" the agent sees status values 0, 1, 2, 3 — and guesses which means what. It picked "failed" records instead of "running" and confidently gave the wrong number.
The fix was obvious in hindsight: give the agent access to the app source code too. It finds the enum (pending: 0, running: 1, failed: 2, completed: 3) and stops guessing.
Blog post walks through real Claude Code conversations showing the before/after, plus setup with DBHub MCP and Repomix for packaging your codebase.

It sounds like / I feel like there's two categories of artists; the one is in it for the art (and would benefit from e.g. a patron or subsidies like the Irish one mentioned elsewhere / also currently on the front page) if their stuff isn't commercially viable.

But the other, and this is the vast, VAST majority of people, create content. Not to be too disparaging, but if the objective is a paycheck then that's what is being made. And this is everywhere - marketing, digital design, video game assets, book series, commissions, etc.

Yes it takes artistic skills to do it, but is it "art"? Is it something (as the comment I'm replying to says) "novel or contextually relevant"? Or is it doing what needs doing because the boss says so?

I think it's important to make this distinction. And that's also the gist of people who want to do art as their day job - there's plenty of work, but you have to accept you're doing what other people want you to do instead of try to do something new.

Yes, "fucking" stood out for me, too. The rest of the text very much has the feel of AI writing.

AI agents routinely make me want to swear at them. If I do, they then pivot to foul language themselves, as if they're emulating a hip "tech bro" casual banter. But when I swear, I catch myself that I'm losing perspective surfing this well-informed association echo chamber. Time to go to the gym or something...

That all makes me wonder about the human role here: Who actually decided to create a blog post? I see "fucking" as a trace of human intervention.
by usefulposter | 2026-02-12 12:35:32+00:00
Genuine question:

Did OpenClaw (fka Moltbot fka Clawdbot) completely remove the barrier to entry for doing this kind of thing?

Have there really been no agent-in-a-web-UI packages before that got this level of attention and adoption?

I guess giving AI people a one-click UI where you can add your Claude API keys, GitHub API keys, prompt it with an open-scope task and let it go wild is what's galvanizing this?
