Show HN: Repo-guide – AI-generated docs for codebase exploration and onboarding
Hey HN, I built repo-guide to make it easier to dive into and contribute to unfamiliar codebases. You can see an example of what it generates here: https://wolfmanstout.github.io/repo-guide/

Unlike most AI documentation tools that focus on Q&A, repo-guide generates comprehensive, browsable guides. It's designed to complement (not replace) human-authored documentation, with full transparency about AI generation.

Why?

* Deepening expertise: One of the best ways to advance as an engineer is to learn how libraries and systems you use are built under the hood. Many AI tools emphasize Q&A chat, which is great if you already know what questions to ask, but not as helpful when you’re trying to discover new details. By generating detailed, navigable guides, repo-guide helps surface interesting design choices you might otherwise miss.

* Onboarding contributors: If you’re new to a repo, figuring out directory layouts and dev tools can be a slog. A comprehensive auto-generated guide lets you ramp up faster.

How It Works:

* You install it via pip install repo-guide, then run repo-guide <path_to_repo>.

* It uses a bottom-up approach that examines each directory and file, generating Markdown docs you can browse locally (or deploy).

* Under the hood, it leverages Simon Willison’s LLM package (https://github.com/simonw/llm) to call LLM APIs (e.g., Gemini 2.0 Flash by default -- you can specify another model via --model).

* The system prompt encourages verbosity so you’ll see thorough coverage of internals (you can customize or shorten this via --custom-instructions).

What’s Next?

* Future ideas include a live chatbot that references both the generated docs and code, plus auto-generated changelogs.

* This is one of my weekend projects, so maintenance might be sporadic, but I’m happy to take feedback and suggestions!
I'm very interested in seeing how he's going to approach adapting this particular part of the story.

I feel like the first two movies of Dune he directed, which cover the first book, were much more world/action oriented as it was that way in the book too. But Dune Messiah is much more introspective so it'll be much more challenging to show the change in the characters.

I'm not really nervous, more so excited to see the adaptation.
Plenty of companies sell their product with 100% margin (look at in-house brands). Maybe not laptops, but this was just an example.
That's a good idea -- it'd preserve the intent of the meme, which is to always be conveying "it has not been as long as it feels like based on events".

As-is, if I visit and see "what a day / it's Friday", that's kinda missing the point.
Thinking that people in charge can correctly identify the bottom/top X% of their employees on some sort of metric is fooling oneself into believing those in power are better than those below them. It’s going to be 10% of _something_.

One episode of Suits comes to mind.

Let’s be honest, firing people reduces cost, because humans are expensive, and executive and ownership class want to keep costs down and profits up. That’s it.

Framing the narrative in terms of firing the worst performing employees puts the blame on individuals.

In a health company, of course if you can’t perform the duties of the job you should be helped to get to that point (if employer is nice) and let go if you eventually can’t. A firing of 100s of 1000s of people at once is a failure from the top in terms of planning.
Even worse, people promoted by hiring into new positions are also on probation and those are probably positive contributors.
It’s better to be outside the aircraft, alive and without your stuff than inside and dead. You can get insulin in any western city.
Hard to disagree in principle.

However, Windows 2000, Windows XP, and Windows 7, and Windows 10 are all crowd-rated quite a bit more favourably than Windows Vista, Windows 8, and Windows 11. So, it seems that there are objective criteria after-all.
Yep, exactly, you want a united front to make it effective, especially when you're dealing with an economy as large as China's. That's why it'd be nice if we were focusing mainly on that, and not also on weird low-value games with other less-abusive and more-ideologically-aligned trading partners.
Spyder is the reason I could become Computer Scientist.

When transitioning from MechE -> CS, every programming interface felt unintuitive and daunting to set up. Spyder made it so simple to get started. It turned python into a Matlab-esque numeric computing interface, got out of your way and let you built whatever you wanted. It reduced the 'time to magic' like no other tool I'd tried. (Can I coin the term : 'time to magic'?)

If I had to setup PyCharm on day 1, I'd never have gone past the my first barrier. Before jupyter & colab, there was Spyder. It remained my trusty IDE for a full year until Jupyter notebooks & VsCode came around.
> Businesses are ran according to the law, and get punished if they don't.

Do you want to spend the rest of your afternoon reading about cases where businesses didn't get punished for not running according to the law? Even in the cases where they are punished, it's often well within the cost of doing business.

> Sometimes that doesn't happen with the govt

For example: right now. We have a buddy of the President deciding to lay off thousands of employees without any respect for the legal procedures for doing so.
It’s not a doubt of abilities, it’s a doubt of his interests aligning with the interests of US citizens.

Here is an unelected NAZI and ILLEGAL IMMIGRANT (worked illegally on a student visa) who did a seig heil at the presidential inauguration taking up an informal unconfirmed-by-congress department head role (DOGE is just US Digital Services renamed) and getting wide access to government systems, and seemingly firing thousands of government employees.

Billionaires, who should not exist, are so rich that they don’t need government services and would rather the government go away so they can make more money. But regular people do need a government, and that’s just one reason of many why Elon shouldn’t be anywhere near policy decisions.

Now, you might say I’m being dramatic. But I’ll say there is no criticism of this man is unfair. He is one of the world’s biggest hypocrites, along with the other MAGA Nazis in his camp.

Please tell me what large organization out there doesn't have at least a few inefficiencies. This notion that only the federal government is bloated and inefficient is so untrue. Every try dealing with or working for a big telecom?
> One is shifting where that manufacturing is done and in the longer term it could bring it back, depending on the cost of doing it in a different, non China, country.

Unfortunately, the taxes in question are also targeting imports from Canada and Mexico, two countries that are firmly in the US sphere of influence, and the beneficiaries of these new taxes will be countries in SEA which are increasingly in China's sphere of influence. This is a geopolitical own-goal from an administration with no coherent strategy.
Wait, next thing you tell me is Mexico will not pay for the wall?!
Its a patently ridiculous example that wildly misrepresents the actual situation.
Works well when you see the company stuffing dollar bills into their sports car to race on 1.25% fuel efficiency against a chinese family sedan with a hand tuned ICE.
So you are a leftist who believes the economy can't operate without basically third world slaves working in your fields?

This isn't unequivocal proof, but the broad goal automation lends itself pretty strongly to LLMs, and oh boy what LLM technology do you think they want to use.
> it seems likely that LLMs will obsolete precisely the skills that developers use to earn their income

I’m not particularly worried. I think it’s obvious that software engineering is definitely an “intelligence complete” problem. Any system that can do software engineering can solve any problem that requires intelligence. So, either my job is safe or I get to live through the fall of almost all white collar disciplines. There’s not a huge middle ground.

Although perhaps this is just the programmer stereotype of thinking that if someone can code, they can do anything.
Why would the US stop trade with China when it invades Taiwan?

The current US reigime seem to be chomping at the bit to restart dealings with Russia despite their ongoing invasion of Ukraine.
Having been on the internet for a very long time, I can answer why open source alternatives to social platforms seldom get off the ground: the network effect is huge, and the community of users matters far more than any of the technology.

Don't bother telling people how it works. Show them who's using it and for what.

Oh, and for any kind of "normie" use it must have a decent moderation and anti-abuse system. Which inevitably clashes hard with "decentralized". Bluesky is succeeding because it lives in a contradiction of pretending to be decentralized, but what it really offers is the "pre Elon Twitter" experience. To basically the same people.

> the same group

While there's a certain amount of hivemind, it's rare that you see people directly contradict their own posts here; what you're seeing is different people.
That's the same percentage profit. And there would likely be some reduction in sales due to the increased price, so the absolute profit wouldn't increase as much as you suggest. Obviously lots of other factors involved.
As far as I'm concerned, the subscription model is an instant showstopper, just like web-based UIs.

This is a particularly bizarre part of the article to me. Certainly Eric Berger, the article's author who's written more than one book on space at this point knows this.

The President appoints NASA's administrator (subject to Senate approval, of course) and Congress controls NASA's budget. How anyone is puzzled by NASA's focus is beyond me. If I'm being pessimistic, I would assume such people are woefully ignorant of how NASA (and maybe the government as a whole) works. I try to be pessimistic instead of cynical because if I were cynical then I would assume a bunch of negative ulterior motives.
If current American government cared about weakening authoritarian governments, it would be supporting them less. If it cared about not undermining Europe, Canada, and other free societies, it would not be attacking them.

It does not seem like Canada wants to be 51 state nor it seems like Europe feels empowered after Trump started to support Putins expansion.
I presume this is only covering Stage 1 of Project 2025 since Stage 2 hasn't been released yet so it can't be FOIA'ed.
I think if we could treat that, we'd also know the core problem.

My hunch (not as an expert) is that people who are very prone to addiction have a maladapted brain system of some kind. I think this system 'malfunction' can either be genetic and/or caused by trauma/environmental reasons in their life. I suspect this because nearly everyone I know that has had addiction problems has had a parent with similar. It's surprisingly rare to find someone with an addiction problem that isn't in the family. Strangely, not all siblings seem to have the same issue.

Problem is, we don't know which system(s) it is yet. The research on kappa opioid receptors is very interesting as the KOR regulates stress response, and we know that stress causes many relapses in previously addicted individuals in recovery.

I also think we may find there are multiple types of addiction, caused by different systems/reasons. These all present very similarly, but similar to the discovery years ago that some infections were caused by viruses and some bacteria, it could be similar for addiction.

So really I think it goes something like this:

People are predisposed to addiction -> they become addicted -> they become homeless and trapped in a chaotic loop which a tiny percent of people can recover from

When I believe the best response for people that are affected by addiction would be something like this

Addicted person (homeless or otherwise) -> some sort of diagnostic (genetic testing?) -> new tailored medication -> recovery

It may be also these maladaptations cause all the mental health problems themselves. But not everyone that has mental health problems becomes addicted, despite experimenting with substances.
Care to differentiate intelligence from emulating intelligence?
They're just firing the people they can legally fire.
It’s not a procedure but not against the rules assuming his parking brake was on. It would be similar to you taking notes in a personal notebook that you keep as a development journal.
I'm not sure I understand how a hallucinating plagiarism machine that people mostly just use to write their term papers translates into "power" (presumably political power? I don't understand what kind of power we're talking about either).
Beyond that, there's economies of scale that won't scale as far, based on lowered demand.

the SLS springs to mind.
Worth noticing that it _doesn't even work at a social media company_. Twitter is a husk of its former self, with all the problems that were if not solved, at least mitigated, back in full force (child porn, bots, impersonators). It's just kept alive because it's a honeypot for right wing nutjobs now (which I'm sure can't read an SEC filing and will claim it's "operating better than before").

It'll be a disaster for the soon-to-be-previous most powerful country on earth...
Yes. Most companies target a profit percentage, not a fixed amount. So if their costs go up, their profits go up. But since everyone does it, they end up still being competitive in the market.
Airline pilots I've worked with have said that this is also why when evacuating the jet in an emergency, they put on their uniform hat. So they're immediately mentally flagged as "authority figure."

Also, there was an emergency a few years ago where a jet lost cabin pressure, and people were getting dragged on social media afterwards for not putting the oxygen masks over their noses.
Trump is the most powerful, he is immune and can commune sentences. If he wants to, he puts Musk in jail tomorrow, no question about that. His successor will be as powerful, whether that is his son or Vance is up in the air. It won't be an elected Democrat though.
> or allow aliasing &mut in single-threaded circumstances where it's known to be safe (i.e. when the data is something primitive like an int, where it doesn't actually matter if it's overwritten while referenced).

Incidentally this is basically what the `Cell` type does. I suspect that making it the default wouldn't make it harder for me to reason about the code I'm working on - but it is an interesting proposal.
You don't hire 22 year olds to do hard work. You hire them and inflate their ego so they will do things they shouldn't, without question. Maybe not there yet (?) But I fully expect these kids to do some highly illegal shit that will land them in prison or worse.

They are effectively a meat shield for Elon who is a meat shield for Trump who ignores the courts anyway.
It is not just that. [0] New Horizons was almost scrapped by Gorge W because of JPL lobbyist that where trying to bloat the project. Where APL was dramatically below and checked all the boxes.

It is also the lobbyist that push bloat to make more money.

Because "looting the USA" is a ridiculous accusation agains someone who is became wealthy from creating genuinely great products. He spent everything he had on SpaceX and Tesla and came incredibly close to losing it all. He is not some robber baron or oligarch who is wealthy by hoarding natural resources.
The propaganda machine has ensure there is no way those AL congress critters can defect without being destroyed.
It changes the entire economics when your random example number keeps things well within the realm of profit whereas the actual tariffs eliminate the entire current profit margin for almost every product in the category we are talking about.
No. It was kept alive by congressional decree for at least a decade after NASA wanted to wind it down.

The explicit reason for this was that parts of the space shuttle were built in 50 states, and the “economic stimulus” trumped things like science or national security.
The demand side.

Less laptops will be bought even if profit per laptop goes up overall profits will go down. Money is finite and these are durable goods. People will now look at other options like the second hand market.
What you're saying does happen to some degree and in this instance, if i had linked some advance with a diffusion model then i would get it but about the only difference between this and chatgpt is the data it's been trained on.
If Open AI cared, the next version of GPT could be a State of the Art weather predictor.
> annexing Taiwan

Grabbing territories by force or economic coercion seems like a despotic thing to do, doesn't it. Even threatening to do so would probably make people trust you less and be less likely to cooperate, I would think.
Actually, the 5 million figure is for the compute cost for the base 600B parameter model. Training R1 was just 8000 steps of reinforcement learning, so I expect that the vast, vast majority of the training cost is already included in the pretraining stage.
Because of the tricky conditions and great view. Presumably they were waiting for that arrival and it’s not every day you get that view of crosswind landings into such a snowy airport.
I prefer to look at reality here instead of an analogy.

The reality is that I get on calls with customers almost every week who tell me how Buildpad has helped them shape and build their products. Many of them are very happy with the help they get. We have multiple founders who have built and launched their products with Buildpad, and we have founders who have started earning money from their products built with Buildpad.

I find that this is more important than the story leading up to the creation of Buildpad.

Now, you're free to be skeptical of our approach, but as I mentioned, my brother has previous experience building a successful business.
Curious that it's rarely mentioned where the tariff collections go. Presumably into the federal budget?
Indeed. I wouldn't even consider buying a Tesla if it means that I'll be funding Incel Stark's future forays into political terrorism.
2M units globally, so maybe generously 1M in the US (assuming you're from there but multiply by some factor proportional to your country's consumeristic tendencies), divided by the population is only something like a .3% rate of ownership. So not quite as prevalent as gopro, which has sold something like 35M in the US over the past 10 years [1]

TIL: Rust does not prevent memory leaks
I'm not a Rust developer so I have no clues about what Rust does, how it does or why it is the way it is.

I had a short interaction on another thread and some user told that Rust does not prevent memory leaks.

People talk so much about Rust memory safety and how everything must be rewritten in Rust, but if Rust does not prevent memory leaks why are people so crazy about it?
Shareholders demand it, even. If your costs increased but your profits stayed constant after your price increase, then a small business owner might be perfectly happy with that. But it's a decline in profit margin so investors would go ballistic.
That’s referring to the cases, not the components.

The cases are made in the US and the machines are assembled in the US. Everything else is likely imported.
In a progressive tax system, the poor end up paying a lot of the taxes of the rich, because the rich tend to own businesses and real estate and they just pass all their income taxes onto the poor in the form of price increases.

If you are a middle class person with a salary in the US you are likely paying upwards of 80% in taxes if you include second- and third-order taxes.

Your rent could be $1000 instead of $2000 if your landlord's income wasn't taxed so much. Your Chipotle meal could be $6 instead of $12 if the franchise owner and their commercial property landlord weren't taxed so much, let alone the workers.

Yeah I think what killed the web was Google and Facebook.

The former brought massive amounts of spam and the latter brought real identies which broke the freedom of the internet.

Or in other words, both brought the Internet and made it real and connected with the real world. And I think that's not a good thing. The Internet was supposed to be a virtual space for exploration, learning, fun, and it should have had no bearing on our actual day-to-day living experience.

But now here we are where Google is a spam filled search engine which hardly returns any products and Facebook is a dystopian wasteland and its founder is walking around like a teenage pimp.
I get the sentiment, but NASA doesn't really compete with SpaceX on anything. They pay SpaceX for launches.

NASA has essentially 0 in-house manufacturing nowdays. Separate question whether that's a good thing, but that's not something the current NASA headcount is doing.

If anything, slowing down NASA slows down launch cadence which hurts SpaceX.
From their design files, it looks like the only things manufactured in the US are the case and the PCB for some of the I/O modules. That's absolutely commendable, it's no small feat and certainly better than nothing, but it's not "mostly" Colorado and the US by any stretch.

Plus, since the main material they use is aluminum and they try to source everything locally, tariffs actually make it more expensive to operate, and unlike in Acer's case it's coming straight out of their profits rather than adding to them through some consumer pricing gymnastics.

Edit: just to be clear, I'm not trying to belittle System76 here. 40 years of "self-regulation" have steadily eroded the US industrial base to the point where there's not much substantial expertise in this field anymore, so they're impressively close to have practically started from scratch. It's an important first step if their long-term plan is to assemble everything from locally-sourced material.
Parent comment was saying that US goths are a reading of European trends.

Meanwhile, I was saying that here (in France) and during my teens, goths where actually seen as a product of American culture.

I wasn't saying that the goth culture is coming from America, but that people who identified as goths were inspired mostly by American artists.
Thanks for the feedback! I'm not used to writing on HN so it's good to know.
Only for the Thelio desktops and Launch keyboards
This was presumably true already, but it's certainly true that some price fixing can happen while the dust settles (if it ever will).
