Hi HN,

I’m the developer behind DayTradingCentral.

The Problem: I started trading a few years ago and realized the tooling landscape is bifurcated: you either use messy Excel spreadsheets or pay $30-$50/month for SaaS journals (like TradeZella) just to get basic analytics like Win Rate and Expectancy. As a beginner, paying high subscription fees while still learning (and losing money) felt like a punishment.

The Solution: I built a dedicated "Command Center" to consolidate journaling, risk management, and analytics into one place.

The Tech Stack:

Frontend: Next.js (TypeScript) for a snappy, app-like feel.

Backend: NestJS API.

Database: PostgreSQL (handling the trade logs and time-series).

Infrastructure: Hosted on Hetzner (dedicated metal) for performance/cost over AWS.

Integration: Native support for MetaTrader 4/5.

Business Model: It is currently free. My plan is to keep the automated journaling and analytics free forever to build a user base. I will eventually introduce paid features for advanced algorithmic backtesting and copy-trading, but I want the core tool to remain accessible.

I’d love feedback on the dashboard performance and the data visualization.

Europe is one of the world's largest agricultural producers and exporters. France alone is one of the top grain exporters globally. The EU exports massive quantities of wheat, barley, dairy, and processed food to North Africa, the Middle East, and Sub-Saharan Africa. Countries like Egypt, Algeria, and Nigeria are heavily dependent on European grain imports. An AMOC collapse would devastate growing seasons, slash yields, and potentially make large parts of Northern Europe unsuitable for current agriculture.

And it's not just food. Europe is a major producer and exporter of fertilizers. If European industrial and agricultural output collapses, the ripple effects hit global food supply chains hard. Countries that depend on those imports will face famine.

Then there's the knock-on, hundreds of millions of people in food-insecure regions losing a key supply source, simultaneous disruption to Atlantic weather patterns affecting rainfall in West Africa and the Amazon, potential shifts in monsoon systems affecting South and East Asia. It's a cascading global food security crisis.

> lots of time to adjust

This assumes a gradual slowdown, but paleoclimate evidence suggests AMOC transitions can happen within a decade or even less. The idea that we'd just smoothly adapt to one of the most dramatic climate shifts in human civilization is not supported by what we know about how these systems behave.

But if we do expand the set under consideration then I'd suggest they do in fact have specific things in common. Large flying carnivorous reptiles. That won't cover all the various edge cases but I think it describes the vast majority of the popular usage of the term.

That definition would imply that sufficiently large flying dinosaurs qualify as dragons. And at least personally I think I agree with that conclusion. Dragons aren't purely fantasy, they're merely extinct (and never breathed fire IRL).

> I don't want people to switch away from Windows; I want Microsoft to treat its premier operating system like it used to

If you don't live in a mythical past, there was nothing "premier", so no categorical change in treatment, so Notepad has always been a bad primitive app you should've replaced years ago and also avoid any along l account bugs in the present (though it's also possible to use the old "premier" notepad instead of upgrading to the account linked one)

I think a lot of investors are looking at Europe/EU as a safe heaven, because it actually has strong democratic institutions that hold up the rule of law, and not some maddening kind that can tank your investments on his mere whim and a tech/fin oligarchy eager to please and profit him while keeping the pyramid scheme going until it blows (while they build doomsday bunkers in New Zealand).
Show HN: One app to command CLI agents across projects - RexIDE
by tomerbd | 2026-02-08 11:02:03+00:00
Hey,

We built RexIDE after juggling too many repos, terminals, and half finished reviews at the same time.

The goal was simple: keep all projects, diffs, voice input for all cli, and AI help in one continuous flow — without switching tools or rebuilding context every time.

RexIDE is built using RexIDE.
I use it daily to manage multiple projects, review diffs, and ship changes from the same place.

What started as a survival tool for multirepo work slowly became the IDE I wished existed.

Any feedback super welcomed! Would you use it? What else would you need? Do you think it fits your flow? Anything else?

> housing stock in a lot of metros

If you actually want walkable, big metro areas are overrated. Look for small towns, that's where walkability rules. The town is small, so everything is near.

Where I live now, most of the town is in a 1 mile radius. And the bulk of it is in a 0.3 mile radius. When everything is small and near, everything is walkable.

As I mentioned, in a 10 minute walk I can reach two supermarkets, one big box store, countless restaurants, several pharmacies, a few bars, stores of all kinds (hardware, clothing, etc), post office, library, theater, movie theater, soccer, tennis and basketball courts and plenty more.

I say if you live in a place where you can't walk anywhere, that's by choice. Tons of walkable places exist all over the US.

Profits = revenue - costs. Costs include depreciations and write offs of investments, and capital costs (what they pay to service debt), before you get to a taxable profit for accounting purposes. It's going to be many years before they pay taxes, if ever.

They do have to pay Value Added Tax on their sales in many countries (all of the EU), but not in most of the US. (The basis for Trump's claim that the EU is robbing the US. Sigh.)

Your quote leaves out the most interesting part: the word is now associated with some particularly folksy folk who notoriously used it in their. genocidal ideology

> The concept was notoriously embraced by the newly founded Nazi Party in the 1920s, and eventually became strongly associated with Nazism after Adolf Hitler's rise to power.

A system that tracks the integrity of each agent and knows as soon as it is tainted seems the right approach.

With forking of LLM state you can maintain multiple states with different levels of trust and you can choose which leg gets removed depending on what task needs to be accomplished. I see it like a tree - always maintaining an untainted "trunk" that shoots of branches to do operations. Tainted branches are constrained to strict schemas for outputs, focused actions and limited tool sets.

> This is Zero Hedge nonsense

Japan has the highest proportion of elderly citizens globally. Moreover, there is extreme economic inequality between older and younger generations. This is a huge problem. Russian has lost 1,200,000 young men attempting to conquer Ukraine which is an expense Japan can't afford.

Japan can defend itself but it is not going to aid Taiwan if China creates a blockade around the island like it did 1 month ago takes over.

> but there are good reasons for using golang.

Such as? If you type in 'C' into HN's search box, the first result is about the F.C.C., followed by C.E.O., then USB-C. Even once we finally see one about a programming language, it is about C#.

If the earlier list was instead 'Clangclang, Golang, Odinlang and Ziglang' then I could maybe understand where you are coming from, but that is not what we saw. Clearly there was no effort put into aiding searchers universally.

Are you trying to suggest that Go is the only language worth reading about? Let me try to restate the earlier question in your tongue: Why is it unique to 'golang'?
by flumpcakes | 2026-02-08 11:10:17+00:00
It's news to me that the UK/Europe has killed millions of people. I think you mean Russia has killed hundreds of thousands and wounded millions.

I can only assume you are talking about Ukrainians in some conspiratorial way; I think it's strange that you remove all agency from a sovereign country and a people who want to protect their way of life. Very strange.

I think that science has advanced to the point, where we no longer consider there to be “unexplored” realms, in science. We haven’t gotten there, yet, but we can see it, from here.

There’s the old adage (maybe it was Carl Sagan that said it?), that any sufficiently advanced science, appears to be magic, but we no longer think of it as “magic.” It’s just a point further down the road. More importantly, we now know about a lot of the “hard limits,” in science.

For myself, I’ve always been more of a fan of fantasy. That’s simply because I prefer the way the narrative is driven.

In Science Fiction, the real protagonist is the speculative science, and the characters are simply decorative elements. The stories are about the “grand idea” science.

In Fantasy, the stories are really about characters, in a fantastical context. The stories are about people.

Relax, before you drafted regulation and rolled it out this bubble will have peaked.

Unless your rolling out dumb reactionary regulation like forbid AI or crypto coins, etc.

It's annoying right now, but on a timescale of 5-10 years ram/gpu prices will be back to normal.

Could we regulate investors reduce risk of bubbles maybe, but it's hard. Probably easier to limit the impact of bubbles on humans with a social safety net.

I had noooo idea how much my interpretation of the world had been shaped by prior lived experience

this is an interesting point. it's very true of course. there is probably some philosophical or biological explanation for this, something about optimization, because interpreting every situation from first principles takes to much effort. living in a different culture is one way to teach you to look at things differently.

but i think it is an issue independent of language. the problem is not lack of ability to describe the experience, but mistakenly using an already familiar abstraction to describe a new experience. but that's not the end of it, because repeatedly making that experience eventually helps you realize that the description you used is wrong, and you adjust to create a better description.

actually a better example than cold is the word umami. in our languages we have terms for sweet, sour, salty and bitter. turns out our body has dedicated receptors for umami, but we were not aware of that, and we never named it. even today it still feels like a foreign concept, but we have evidence that it is a real biological experience and not just a cultural idea.

the thing, is we certainly experienced umami in some way, but we could not talk about it, we were not consciously aware of it. and we still are not. i can tell very sweet from somewhat sweet to not sweet at all, but what's very umami or not umami? how does that even work? there is a whole dimension of language that our culture is missing. but, it's a cultural problem, not a linguistic one. because now we do have a word for it. and still, at least i struggle with the concept.

interestingly i think this example shows how humans learn from context. our (western) culture is missing the context for umami. we need to build up that context to allow others to learn about it.

What would be great, and I don't know if @dang / the mods would take on requests like this, would be for bot participants to be allowed but the account flagged. So e.g. the user name just says "[bot] Zakodiac" or something.

As well as being an ethical approach - I think it's wrong to try to impersonate humans and/or not announce AI output as AI - it would also be handy for new filter options: all bot posts are OK, hide bot leaf comments, or hide all threads with bot comments. etc.

Show HN: Competitor Finder API – find real competitors from one hostname
by maximedupre | 2026-02-08 11:16:11+00:00
I built a Competitor Finder API. You send a hostname, it returns 5-10 real competitors with why they match. Most domains come back fast, but if we need a fresh crawl it can take a few minutes.

Price is simple: $0.10 per competitor; optional enrichment is another $0.10.

It can be used to improve your onboarding or enrich your datasets!

I’ve been experimenting quite a bit with AI-assisted development recently (Copilot, Cursor, Claude, etc.), both in larger systems and in smaller side projects.

What keeps surprising me is not hallucinations or model output quality as such, but how easy it is to lose shared architectural context over time.

At first everything feels great. Things move fast. Demos work. Features pile up.

But after a while I notice that parts of the system were built differently than I would have designed them myself. not necessarily wrong, just inconsistent in ways that are hard to see early.

Nothing breaks right away.
But at some point I realize I wouldn’t feel comfortable taking full responsibility
for the system anymore, especially under (long-term) production constraints..

What I’m struggling with is this:
How do you keep architectural intent explicit when AI is writing a lot of the code?

For me it seems less like a prompt or a context window problem and more like a governance issue: Which decisions must stay stable? What must not change? Where is AI allowed to explore, and where should it be constrained?

I’ve started experimenting with more explicit roles, workflows, and step-by-step development phases, but honestly I’m not convinced yet this is the right balance.

I’m curious how others handle this in practice:
How do you get real speed from AI tools without slowly drifting into a system you no longer fully understand or trust?

In the sense of a farmer being more likely to have access to a local supply of firewood, and that tractors are probably more used for longer stretches at a time than running down to the grocery store, sure.

Historically, they weren't that common, as large-scale use of wood gas was mostly a thing in Europe during WWII, and during that period continental European agriculture was still mostly horse-driven. After WWII when agricultural mechanization really picked up, fuel was again available so there was no big motivation to put up with the disadvantages of wood gasifiers.

> But more importantly, LLMs aren’t stateless across executions, which is a huge no-no.

They are, actually. A "fresh chat" with an LLM is non-deterministic but also stateless. Of course agentic workflows add memory, possibly RAG etc. but that memory is stored somewhere in plain English; you can just go and look at it. It may not be stateless but the state is fully known.

You’ve just written the exact reason LeeteCode is widely mocked as an interview technique. They are not representative of most real world software, and engineers that train to solve them give a false impression of their ability to solve most other problems.

I’ve interviewed hundreds of engineers for software and hardware roles. A good coding test is based on self-contained problems that the team actually encountered while developing our product. Boil the problem down to its core, create a realistic setup that reflects the information the team had when they encountered the challenge, and then ask the candidate to think it through. It doesn’t matter if they only write notes or pseudo code, and it doesn’t matter if they reach the wrong conclusion. What it’s testing for is the thought process. The fact the candidate has to ask the interviewer questions as though the interviewer is effectively the IDE, is great! The interviewer experiences the engineer’s thought process first-hand. And the interviewer can nudge the candidate in the correct direction by communicating answers that aren’t just typical IDE error messages.

To validate these kinds of questions in advance, I’d often run them on existing team members that hadn’t already been exposed to the real challenge the problem was based on.

Hi HN,

I built this as a small side project because I personally dislike updating my CV and found most tools either too complex or paywalled.

The goal was to see how minimal the process could be while still producing something clean and usable. No monetization, no ads — mainly a learning project and an attempt to build something genuinely useful.

I’m especially interested in feedback around:
- UX (particularly on mobile)
- What feels unnecessary
- What feels missing

Happy to answer any questions.

I was reading up on head-carrying the other day. Here's some fantastic articles on the topic, and especially about the use of "tumplines" (strap on top of head with ropes that go around the thing being carried)

I started training with one and a 33lb bundle of firewood the other day, and my back and neck haven't felt this good in a long time. I'm going to continue increasing weight, and might also try carrying things directly on top of my head without the tumpline.

I switch between Tahoe, fedora and pop_os on a daily basis. Tahoe in its complete design madness is still in a league of its own when it comes to basic UX IMHO. Just the fact that the keymappings for undo/redo are consistent between apps puts it’s way ahead of Linux when considering the whole ecosystem. Linux is a clear winner in tech and tooling thought, which is why I use both.

Agree on the observability. Every time I've seen that mentioned on the many, many discussions on Xitter theres one of the usual clickbait youtube 'bros' telling you to go watch their video on how to make your own ui for it. Really shouldn't need to for such a fundamentally basic and crucial part of it. It's a bit of a hot mess.
by throwawaysleep | 2026-02-08 11:22:35+00:00
I lean towards the latter.

I am personally much less tolerant of human personality differences because LLMs mean that if the other person is mostly providing additional capacity, I no longer need the other person.

At one of my jobs, nobody wants to bother onboarding the new people as LLMs make it easier to just do their work rather than deal with a confused new person.

I’ve performed many experiments using AI to reverse-engineer old games like this one, and it looks like the newest generation of models has no trouble with it. They’re actually awesome.

Even with the current models, we might be able to automatically reverse-engineer all those old games, decode all assets, and even rewrite them in a more sensible language than assembler.

It’s a double edged sword. The computer at this point is 7 years old and had slowed down (planned obsolescence). It’s not exactly going to be anything like a new computer. And Linux for that is perfectly fine for everyday tasks and what you can get from a 7 year old computer before the ARM chips entered the scene. On the other hand if you did buy a new computer you’d probably get to run the latest windows and macOS versions running perfectly fine in which case he’s probably complaining about how bad Microsoft and Apple have gotten over the years which is why he’s giving Linux a try in the first place.

It feels like the author entered with the bias of complaining and frustration no matter what by comparing a weakness with others strength.

Raiders of the Lost Ark is one of the best games for the Atari 2600 and I say this without any nostalgia for the title. It's an early adventure game and has a kind of complexity absent in most Atari 2600 games which, based on today's standards, are largely stupid. I've discovered things about this game years later by reading a walkthrough... It has a point system similar to the Sierra games because some activities are actually optional, a breakthrough feature.

In fact, the Howard Scott Warshaw games are great: Yars Revenge, a simple but classic game and E.T., the victim of one of the most unfair public lynchings of a game ever.

> What you're positing—that as various areas of the planet warm and cool, there will be perfect balance in what arable land we lose and gain

I am not, and never did propose that. I am arguing that there is no model that I am aware of that predicts a such dramatic NET reduction in arable area that society collapses. If you know of such models, now would be a good time to make me one of the lucky 10k :-) The only ones I am aware of are those predicting specific collapse on specific populations, most of which are tiny, percentage-wise.

> What it looks like to me is that you are either handwaving the decades (or more!) of turmoil, hardship, and loss of life for people in the areas that will be most affected by this,

No, I am not. Respectfully, you appear to be ascribing intentions to my argument that I don't have. I quoted the bit I was responding to specifically!

>>> I can't help but think of all the historical societies that collapsed due to even mild pressure on the food supply.

To which my answer is that this is very unlikely - there will be turmoil, hardship and (some - they aren't going to all die) loss of life in the affected currently-arable areas, but society does not depend on any specific area being viable.

The largest societies live nowhere near their source of food. The impact is not the same as the quoted "historical societies" that collapsed when the arable land did, because our societies don't have the dependency of "living on or near arable land".

Will there be a negative impact on those people living in and around arable land? Sure. Are they a significant percentage of our societies? Nope. Single-digit percentage of the population is nowhere close enough to cause a societal collapse.

All of this to say that, what happened to historical societies happened because those societies were built in, on and around their basic nutrition requirements.

Our societies are not.

Creator of Matchlock here. Mostly for performance and usability. For interacting with external APIs like GCP or GitHub that generally have huge surface area, it's much more token-efficient and easier to set up if you just give the agent gcloud and gh CLI tools and the secrets to use them (in our case fake ones), compared to wiring up a full-blown MCP server. Plus, agents tend to perform better with CLI tools since they've been heavily RL'd on them.
