Ask HN: Anyone running AI agents in production without engineering background?
by vincentvandeth | 2026-02-23 12:46:26+00:00
I've been building production systems with Claude Code for 6+ months — multi-agent orchestration, automated quality gates, web crawlers. No CS degree, no engineering background (except if you count BASIC in the 80's)

Architecture-first approach with AI doing the heavy lifting.
Curious if others are doing the same.

What's your stack?
Where do you hit walls? How do you handle quality without a traditional engineering team?

BuyFromEU is the funniest subreddit there is right now. Unintentionally but still entertaining. EU has managed to paint itself into unenviable corner. I can't buy from EU even thought I want to because for physical goods - cross country shipping costs are prohibitive and for digital - they are either subpar, more expensive or both.

Try this as experiment - try to buy something like precision dowel pins from Poland or DOLD Mechatronik with shipping to Greece, Bulgaria or Romania vs the same thing from Aliexpress or Temu. Chinese costs are cheaper even if they have to fly here.

AFAIK one of the reasons they held onto 'alpha' for so long was that this network lag issue for internet based play was a big known and hard to address issue. I'd def be trying again since they've come out of alpha with this release.. a huge deal for a game that is so many years in development.

Also, we've always played the game as in-person LAN, and for the most part the lag has been just fine. Only for really huge end of game final battles with the screen packed with troops did it lag out for us, but being free and all, we'd often gather around one monitor and talk crap at each other while we waited for it to clear up.

Good times.

Be precise in such serious accusations.

Be precise about the harm done to the community, which I've been part of for longer than it's newer members have been alive. A community in which my accurate forecasting of "risk of ruin" type outcomes has error bars between 60-90%.

Be precise about what a healthy HN means, because that's not written down anywhere, the guidelines such as they are? A masterclass in selective enforcement of blank-check norms for money.

You've got the same dataset I do, and exactly the same access to legitimate authority as opposed to self-arrogated police powers on behalf of public benefit corporations which have neither benefited the public nor a shareholder.

I was here long before you or Dan, and if you ban me, it will be the wedge I need to move this conversation somewhere else.

Let's dance.

Eunoia is an emerging logical framework for specifying the
proofs and proof systems of SMT solvers, namely CVC5. We present a
translation from Eunoia to the λΠ-calculus modulo rewriting as implemented
by the LambdaPi proof assistant. The translation is implemented by our
tool eo2lp, which we use for generating LambdaPi encodings of (a) a large
fragment of CVC5’s Cooperating Proof Calculus (CPC), and (b) proofs
produced by CVC5 on unsat problems from various fragments of SMT-LIB.

I didn't mistake you for that at all. I didn't give any thought at all to that, in fact.

My point was that this "more even than it did for the outside world" seemed to downplay how strongly this view of Google from the "outside world" is held.

I just found it amusing that people at Google would assume even my first comment was indicative of being at Google, much less my second comment, rather than being a totally normal thing for someone outside Google to think.

I'm not surprised to hear that this hold inside Google as well. You just don't need any inside knowledge of Google to hold this view.

Hi HN, I built this because I trade XAUUSD with AI agents and kept hitting the same wall: the AI forgets everything between sessions.

TradeMemory Protocol is a 3-layer memory system (raw trades → pattern discovery → strategy evolution) exposed as MCP tools. Any MCP-compatible AI agent can plug in.

Stack: Python, FastAPI, SQLite, Claude API for the reflection engine. 36 tests passing, MIT licensed.

My own quant system is the first production user. Would love feedback from anyone building AI agents or doing algo trading.

Happy to answer any questions about the architecture or MCP integration.

“I don’t find their actual search engine very useful at all.” (me in 2009)

I'm quoted on here so I thought I should give an update! :-)

I still don't think DDG was very useful in 2009. A noble idea, but the quality wasn't there for the searches I did. In the past several years, I've found it to give Google a good run for its money, both through DDG's index getting better and Google's getting worse. I'm delighted they've made a real go of it.

The best way is the most natural : speaking it, regardless of ability.

Get a native speaker, ask them to teach you the very basics, get them to keep speaking the language to you and correct you as you go. It doesn't matter how laborious it is as long as you're _active_.

At the point you can get a basic conversation going you can start actually looking at the grammar and the written language.

As a human being, your brain is made for spoken language first. Writing is still new and cognitively less important.

> Honestly, I think it was probably a few users abusing the system like crazy.

It's not unusual that 10% of users use up 80% of the capacity; first saw this when home internet started getting ubiquitous.

By dropping the problematic 10%, the remaining 90% are:

a. Much happier, and

b. Much more profitable for the provider.

Resulting in a sustainable service for those who don't abuse the hell out o the ToS/FUP.

This is an awful experiment. Only consumers care about delivery costs on deliveries like these, and what you're looking at are explicitly not goods aimed at consumers.
Show HN: Agentic programming needs new processes
by agereaude | 2026-02-23 12:51:12+00:00
Most teams using AI coding agents are treating them as faster typists. Same sprints, same workflows, same two-week cycles, just with an LLM doing the typing. I think this fights the tool instead of leveraging it.

A new programming paradigm needs new processes and ways of thinking about problems. And no, this is not about increasing productivity by measuring number of PRs.

And what about all of the previous ~40-50 centuries where cities were centers of learning and art and not Hobbesian hell holes? Ur is slightly older than the 19th century, I believe.

And note that there is evidence for cities of tens of thousands of inhabitants from 3000 BCE, while Rome reached 1 000 000 residents by 1CE. Again, without becoming some Hobbesian nightmare.

Okay. Then buy pizza oven from Italy and see how shipping costs are 60% of the price of the oven.

Anyway - you seems to misunderstand. If transporting something from Shenzhen to Franfurt is cheaper than transporting the same thing from Krakow to Thessaloniki - means that EU has fucked up royally in its main mission - to facilitate movement of goods. WE have ungodly patch of local carriers and courier companies and a lot of friction in every kind of intra eu goods movement.

Stereo cameras are useless against repeating patterns. They easily match neighboring copies. And there are lots of repeating or repeating-like patterns that computers aren't smart enough to handle.

You can solve this by adding an emitter next to the camera that does something useful, be it just beaconing lights or noise patterns or phase synced laser pulses. And those "active cameras" are what everyone call LIDARs.

I really love that their notification email includes applicable price change for my specific servers.

The worst counter example of this was Mercedes sending me an email saying "the terms and conditions have been updated, please read them at this link". It linked to the 52 page document I was supposed to read through in its entirety and manually diff against previous! Good thing they started adding a change log in the emails after some customer push back.

> 10/10 - would generate tens of thousands of lines of useless code again.

Me too! A couple days ago I gave claude the JMAP spec and asked it to write a JMAP based webmail client in rust from scratch. And it did! It burned a mountain of tokens, and its got more than a few bugs. But now I've got my very own email client, powered by the stalwart email server. The rust code compiles into a 2mb wasm bundle that does everything client side. Its somehow insanely fast. Honestly, its the fastest email client I've ever used by far. Everything feels instant.

I don't need my own email client, but I have one now. So unnecessary, and yet strangely fun.

Its quite a testament to JMAP that you can feed the RFC into claude and get a janky client out. I wonder what semi-useless junk I should get it to make next? I bet it wouldn't do as good a job with IMAP, but maybe if I let it use an IMAP library someone's already made? Might be worth a try!

I've dabbled a bit in Ada, but it wouldn't be my choice either. It's still susceptible to memory errors. It's better behaved than C, but you still have to be careful. And the tooling isn't great, and there isn't a lot in terms of libraries. I think Ladybird also has aspirations to build their own OS, so portability could also be an issue.

This paper describes the front end of SETI@home and provides parameters for the primary data source, the Arecibo Observatory

Most of this data was recorded commensally at the Arecibo observatory over a 22 yr period

Interesting as Arecibo collapsed in December of 2020. It sounds like they have a lot of data to still churn through.

Memory prices are so stupid now that 575% is pretty close to their actual costs.

AFAIK, it's been stabilizing lately at the current price, so at least it's not increasing anymore: https://pcpartpicker.com/trends/price/memory/

By the same time next year the prices likely gone down, although maybe not to the pre-increase, but surely much lower than currently. Putting it in my calendar to revisit this comment in a year :)

QC / Cheap Shipping / TEMU or AliX Pricing

Pick 2.

Not to mention that from July 1, 2026, the EU is abolishing the €150 duty-free threshold for non-EU shipments. This is specifically targeted at the flood of packages from marketplaces like Temu and Shein.

From July there will be a flat customs duty of €3 for small consignments. This fee applies per category. If your package contains items from different product groups (e.g., a shirt and a cable), you might pay the fee multiple times.

The Goal: To create fair competition for European retailers who can't compete with subsidized shipping and tax loopholes from massive non-EU sellers.

This will obviously have a knock-on effect for larger shipped items which are presumably subsidised at the bottom line by these parcels of fast-fashion and eWaste.

> Modern C++ pretty much solves the safety issues.

I always wonder how can one come to such a conclusion. Modern C++ has no way to enforce relationship between two objects in memory and the shared xor mutable rule, which means it can't even do the basic checks that are the foundation of Rust's safety features.

Of course, this statement is also trivially debunked by the reality of any major C++ program with complexity and attack surface of something like a browser. Modern C++ certainly didn't save Chrome from CVEs. They ban a bunch of C++ features, enforce the rule of two, and do a bunch of hardening and fuzzing on top of it and they still don't get spared from safety issues.

I actually went through the same VS Code articles and ended up implementing a minimal Piece Table for this project. I focused on adding just enough functionality to handle Undo/Redo according to my specific needs.

So far, it has been working well for my use case. Since the codebase is compact, it is straightforward to test and maintain. For a solo project, I've found that using a data structure I can fully grasp is an advantage.

I’m interested to see where your project goes, whether you stick with Piece Tree or pivot. Building an editor from scratch is a unique experience, isn't it?

> but no one wants to use a pay-phone when they have their own mobile!

I have a hobby-level interest in avoiding pervasive surveillance, and have been thinking about ditching my phone more often. Something like no-cell Tuesdays.

What if I have a family emergency? I don't have a desk phone, but I could pay more attention to my work email.

What if my car breaks down? I could use a payphone, except those don't really exist these days. I could walk to the nearest gas station and ask to use their phone, but they would probably think I was crazy.

The other thing payphones used to have (at least here and there) was an attached phone book with Yellow Pages where I could find a tow company. Lets say I do manage to beg access to a phone, how do I know who to call?

Now that everyone carries all these things in their pocket, other systems for handling these problems have atrophied.

It is set to 2 seconds based on `cat /sys/module/usbcore/parameters/autosuspend` but the input latency only happens in games. Outside of games it's fine. Also in game, if I continue to press keys faster than waiting 2 seconds, it still lags.

That makes it unlikely it's related to this auto suspend, especially since it only appears to happen when I use my 4k monitor, but I did set it to 30s just to rule it out and it made no difference. I brought it back to 2s afterwards.

One thing people don't realize with regard to smart thermometers is that they're a goldmine to people who break into houses.

A 51 straight weeks of 70 degree temperate followed by a week > 70 might imply they're on vacation. People who turn down the heat/ac and turn it back on when they come home from work is also a pattern pretty apparent by that info.

> That is a lie. It's the excuse they are giving

Actually I came to that thought independently, then saw others saying the same. And you can't say it's a lie because you don't know how their backend works. I assume you know of prompt caching; that's one way to huge token savings, and works best with a cooperative client. I've also noticed that whenever I send an initial prompt to their web chat, the first message that pops up is the system trying to find skills that can handle the request. Who knows what skills they have available that can handle special cases and thus also contribute to savings, which also requires a cooperative client.

> some orthogonal product.

That's just your assumption. And if they really are "keeping the price artificially low", it's still to the benefit of users who don't mind the condition of using an official client. It's absolutely up to them how they run their business, as long as they aren't actually exploiting users in a market they've cornered (which they can't with all the providers out there).

> It's not sustainable

If not then eventually they'll up the price, or drop it and only offer the per token API. Until that hypothetical there will still be those who benefited from it while it was though. Nothing can change the fact that they've been offering users great value. It's kinda wild you're trying to detract from that even now, with 0 basis. Enjoy Ollama Cloud.

Agreed. They said they ruled out rust in 2024, I believe the article they published was near the end of 2024 because I remember reading it fairly recently.

Seems like a lot of language switches in a short time frame. That'd make me super nervous working on such a project. There will be rough parts for every language and deciding seemingly on whims that 1 isn't good enough will burn a lot of time and resources.

> If I made a good point, you could have signaled agreement.

Great point! [Deliberately mimicking an LLM here—not dismissively, but in jest.]

In all serious though, I understand where you’re coming from and I am aware that my approach throughout this thread is agitating. My response was a legitimate attempt to express appreciation for the time you spent answering my questions.

To be honest I was hesitant to signal agreement because I was worried that you’d interpret the entire exchange as me goading you into a point that I otherwise could’ve made on my own. I didn’t want you to think that you were working for my approval.

> where does good-faith asking questions from a non-fully-fleshed-out place actually fit in modern large-scale Internet forum discourse? It's a crappy dynamic…

Hope you don’t mind the ellipse where I left it. I do agree with this all though. And I don’t think the dynamic is inherent crappy [1], but in society’s current state and especially online it is; particularly when a certain line of questioning can be reasonably interpreted as provocative instead of curious or congenial at best.

Are we supposed to signal to each other that we are of the same ideological tribe beforehand? And what if we aren’t?

[1] I did break the quote there to gently diverge from what you actually said about reflexively jumping against the dynamic; In a way I don’t think I’m diverging though, maybe giving my take on why it’s crappy to jump, in a way I’m claiming my own judgmental stake alongside your own.

I know what I’m doing puts a strain on another person’s the cognitive bandwidth. I think that’s sort of the point. In return I reckon I presume the role of a knave.

What’s interesting is seeing how long a person tolerates my advances and how their answers develop.

Lately my primary motive is to try to drive discussions past exchanging platitudes toward something more…I don’t know yet. I started with that LLM reference for a reason but this comment is already long. If you even read this maybe you can sort of catch my drift.

Same, I tried DDG a bunch of times over the years, maybe once every 2 years or so, but never got to the point where it felt it could replace Google.

Tried Kagi when it launched, and I'm not sure if it was because Google had deteriorated so much at that point, or Kagi was simply better, but I got way better results in Kagi, and still do. Kagi ended up being what I thought DDG was aiming for, but was never able to reach.

> great video on Youtube from Technology Connections

I don't understand why you're trying to cite conspiracy theories propaganda that's aimed at people with double-digit IQs. His videos are filled with distortions and manipulations, and do not address the real challenges facing the energy sector.

And no, there's no mention of batteries there; it's literally a straw man fight, showing their applicability to daily solar power generation cycles while almost completely ignoring their applicability to annual cycles.

> Solar is literally, and provabley, cheaper than gas. Including the cost of batteries

This is simply not true, considering that people actually need more electricity during the few weeks of the year when solar panels produce the least. It's precisely these few weeks that make solar energy more expensive than fossil fuels.

Just take a weekly chart of the actual energy output of the panels for the year, and calculate the price relative to the worst week

I don't understand why we need to engage in conspiracy theories and pretend that humanity hasn't abandoned fossil fuels because the Jews who rule the world love oil or something (and not because it's simply cheaper).

> That's why something like 96% of investment in new energy is in solar or wind now.

That's because the pedophiles who run the world can charge me 30 cents for electricity instead of the 3 cents it would cost if it were generated by fossil fuels.

Google's "pipe syntax" is a similar idea: [0]

It's not as elegant as PRQL, because of course it's bolted onto the existing SQL syntax, rather than a redesign from scratch. But it has a big name behind it, and it's actually running in prod in Google Cloud... so it might have more momentum.

This is an interesting profile of Terence Tao as an ~8 year old: https://gwern.net/doc/iq/high/smpy/1984-clements.pdf, written by somebody who seems to have been well-versed in working with mathematically precocious children. It's interesting less for how good at math Tao already is but a peek into how he went about learning and doing math at a time when the subject matter was still accessible to, say, most users here. Among other things, what might be called his "openness to math experience" and independence are both remarkable.
