RAG definitely is helpful! Fine-tuning imo is extremely powerful but it's still relatively alchemy - technically gpt4, Claude any large model is a finetune of a base model! Reasoning finetuning is also very powerful!

If you read what they think the problems to solve are, you will get it.

small edits to code yield enormous Git diffs;
code is copy-pasted across notebooks, instead of reused;
magic commands limit the portability of notebook code;
logic that would be useful as a script or library gets thrown away;
logic that should be tested almost never is.

These are problems primarily a software engineer has. Not problems a scientist thinks are important. If you asked a scientist to list problems with Jupyter notebooks (and there are many), it would be very different list, primarily about science.
This is their first model to only be available via the new Responses API - if you have code that uses Chat Completions you'll need to upgrade to Responses in order to support this.

> In Ithaca though we have a population of hypochondriacs who are notoriously left wing.

I had the same group of people living and doing yoga in a castle near my mother's home, that i would have described as left-wing hypocondriacs, extremely skeptics of modern medecine. A majority voted "right-wing" at the last european elections.

So using left-wing or right-wing is not a good way to describe this kind of group. They clearly have a minority habitus that could push them to vote "left-wing" (as long a they are not in power), but also share an anti-science sentiment that can push tehm easily towards a populist right (populist != bad in my eyes, i do think populism in politics is necessary.

> People can decide to do what they want

Indeed. And one of the things they can decide to do is figure out what the motivation was behind this is. No one has to justify that either.

But it's not hard to justify. If I worked in the environment Asahi left because she said she didn't feel safe in it, I would be trying to find out what happened and in particular if it was likely to effect me.

If I was Asahi and didn't want that sort of speculation, step one would be to just leave it at "I've paused work on Apple GPU drivers for personal reasons". As it is saying it was because the environment is unsafe, but not saying why it is unsafe makes it look to me like speculation is subtly being invited.
I run a SaaS business, and whilst disputes are rare, I'm pretty sure most of them are from customers who forget to cancel their subscription. Rather than emailing me asking for a refund (which I'll be happy to give), these customers go straight to the dispute process.

Once a dispute is opened, what are my options?

- Send a super nice email to the customer asking to withdraw the dispute and promising to refund their payment/s

- Contest by submitting evidence. What evidence is there to show that the customer DIDN'T cancel a subscription?

Both of these processes are laborious and rarely worth the time. And regardless of outcome, the original dispute fee is not returned in my experience.

This feels unjust such that the psychological cost of a dispute outweighs the financial cost for me. I get that merchants should be disincentivized from engaging in dodgy businesses, but even when a merchant does everything right, disputes still happen.

I would like to see a simple, penalty-free option for dispute resolution, similar to:

1. Merchant receives notification of customer's intent to dispute. Merchant has 2 weeks to review the claim.

2. During this window, merchant can refund the payment/s, either accepting the dispute, or refunding as a courtesy. If payment/s are refunded, the case is closed, and no penalties are incurred (apart from transaction fees).

3. If the merchant contends the customer's claim or doesn't respond, the matter becomes a dispute as it exists currently. A fee is withheld, and the merchant can submit evidence within a given time. However unlike the current situation, the fee should be borne by the customer if the merchant is successful. If customers risked a penalty of opening an unsuccessful dispute (especially a non-fraud dispute), it would likely reduce the number of groundless/fake disputes.

Thanks for the feedback! The term "PRD" is pretty overloaded in that it's often used interchangeably by engineers to refer to technical design docs/requests for comments/spikes/etc (people really need to align on a single term for these), so I used it here to capture everything.

Show HN: I Built My Startup Using My Own AI Tool–Here's What Happened
Hey all,

I’ve always believed that starting a business should be easier. The brainstorming, the research, the branding—it’s exciting, but it can also be overwhelming. I wanted a tool that could take an idea and fast-track it into reality.

So, I built it. StarterPilot. An AI-powered platform designed to help entrepreneurs go from “what if?” to “let’s launch” in record time. But here’s the crazy part—I used my own tool to build my startup.

I started with my idea—an AI-driven assistant that could validate business concepts. Within seconds, StarterPilot analyzed market demand, revenue potential, and even risks. It gave me insights that would’ve taken weeks to research on my own.

Next, I needed a name. Instead of agonizing over it, I let the AI Name Generator do the work. It suggested creative, available names, and even checked domain and social media availability instantly.

Branding? Done. The AI Icon Generator created a sleek logo in seconds. I tweaked a few designs in chat, and boom—my startup had a face.

Then came the landing page. This part usually requires hiring a developer or wrestling with templates. Instead, StarterPilot generated a professional-looking page for me in minutes. I made a few AI-assisted edits, and just like that, my startup was online.

It was surreal. The same tool I built to help entrepreneurs had just launched me.

Now, I’m using it to help others turn their ideas into real businesses—without the stress, without the guesswork. If you’ve ever had a business idea but didn’t know where to start, maybe this is the shortcut you need.

The author takes great care to rebut a common theme among objections to the proposal - “this isn’t necessary if you just write code better”. I am reminded of this fantastic essay:

> If we flew planes like we write code, we’d have daily crashes, of course, but beyond that, the response to every plane crash would be: “only a bad pilot blames their plane!”

> This doesn’t happen in aviation, because in aviation we have decided, correctly, that human error is an intrinsic and inseparable part of human activity. And so we have built concentric layers of mechanical checks and balances around pilots, to take on part of the load of flying. Because humans are tired, they are burned out, they have limited focus, limited working memory, they are traumatized by writing executable YAML, etc.

> Mechanical processes are independent of the skill of the programmer. Mechanical processes scale, unlike berating people to simply write fewer bugs.

Not as fringe as you may believe. Raymond's book sold a lot of copies. But more impactfully, radical feminist ideas on this topic and others continued to develop, and became increasingly influential from then to now.

One aspect of this that often isn't considered is how women with shared feminist ideals but differing political backgrounds have been working together across the aisle. As a result, radical feminists on the left have had significant influence on conservative policymakers via these informal collaborations. Look at EO 14168 for example.

I can report that I tried this setup (Claude Desktop on Linux + codemcp) on the Rust uutils repo asking it to add a "--repeat" option to cat to repeat the output N times (without telling it anything else), and it has generated a commit that looks plausible, correctly locating the implementation file and unit test file and changing them in an apparently correct way (other than mangling a commit just before the code changing \\n to \n).

It did require to manually enter "continue" in Claude's chat (and to approve the use of codemcp at the start), but it otherwise did everything automatically.

It seems to work.

codemcp automatically produces and commits a single git commit which also contains commit hashes for a bunch of other commits that contain a subset of the changes.

> “The Hebrew Bible equally bans eating the pig, the camel, the hare, and other animals,” he says. Fish without scales, rock badgers, and certain birds were also off-limits.

> Muslims took a middle ground, rejecting most Jewish dietary restrictions but accepting the prohibition on pork. The Koran says the pig is unclean and therefore forbidden, along with blood, dead animals, and animals not dedicated to Allah.

The discrepancies can be traced back to the house of Abraham, where both Jews and Muslim claimed the lineage of their religious authority and laws.

According to Muslim traditions eating pork prohibition is existed since the very early beginning of human and perhaps can be traced back to prophet Noah time.

The thing with the Jews is that regarding the many dietary constraints because they have three approaches for prohibitions:

1) Original prohibitions from their one God (similar to Muslim since they're both from the house of Abraham) and eating pork prohibition is part of the original commandmends

2) Extra or additional dietary constraints from their one God as form of punishments for their corrupt and evil deeds

3) Self imposed dietary constraints not ordained by their one God but by their very own pundits

These 3 dietary things become accumulated, mixed and covoluted by the scribes of Jewish religious books as if they were all comes from their one God commandments

When Islam come it reverted back to the original dietary constraints of the house of Abraham. Please note that he is not a Jew but a prophet sent to the Semite people, and the father of Ishak and Ismail, whereby both are also prophets, and the progenitors of Jewish and Islamic faith, respectively.
home ownership is directly tied to rental affordability, as the rental market is always going to be the alternative. Even if people aren't perfectly rational agents, everyone has their own subjective present value function or heuristic to compare the cost of owning vs renting. They may be separate forms of tenure, but they do in fact compete with one another on price/value. If the price of alternatives to ownership were to fall, the price homebuyers are willing to pay would also fall.

> [multifamily housing units are] not really the kind of place that most people want to buy to live in

this is a descriptive norm - observed or perceived behaviors, preferences, and trends among a group of people who, typically, don't really have a choice to buy anything other than a detached house. Family-sized condos are actually highly sought after in dense urban areas where a detached house is an overt luxury, while in suburbs and rural areas they're a rare choice simply because it's illegal to build them.
As far as I'm concerned, all of the other models are a waste of time to use in comparison. Most people dont know how good this model is
