And this is the ignorance we have to fight against.

I'll repeat this for those in the back:

TARIFFS ARE PAID BY THE CITIZENS OF THE COUNTRY DOING THE TARIFFS.

TARRIFFS ARE NOT PAID BY OTHER COUNTRIES.

This is excessive and illegal taxation without representation. Congratulations, party of low taxes, you now have socialist-like taxes without any of the socialist benefits.

> For Security Professionals (us): Stop being gatekeepers and start being enablers. Put down the "How do you not know this?" attitude and pick up the "Let me explain why this matters" approach.

Eeeehhhh… gatekeeping is, IMO, not quite the right term.

On the one hand, gatekeeping is restricting access until conditions are met, regardless of how spurious and irrational those conditions are. And usually, despite some pretty insane conditions. Questioning the fundamental competency of someone who ought to know even just a little better is challenging why they aren’t already possessing access, not preventing access in the first place.

On the other hand, most people in the IT industry love to talk about all the little shinies they are obsessed about. So while they may not be the best teachers in the first place, tickle their passionate shinies hard enough and they will talk your ear clean off, down the hallway, drop it through the lift and have it staggering bloody and beaten onto the sidewalk outside before you can get a word in edgewise. So getting people in IT to be advocates for the work subjects they are passionate about is not the problem - it’s training them how to deliver that information effectively to someone not in the know and not initially passionate about it.

On the gripping hand, there are plenty of people in almost every industry for whom ”How do you NOT know about this core component of your job??” is a very valid criticism to lob with great enthusiasm at them. A verbal shock like this can be very useful for disturbing a person out of their complacency, especially if they already see themselves as an SME. The real trick is following that statement up with something that can truly inspire and encourage them to willingly reach for competency in that component.

On the topic of RAM, I was recently researching the vintage IBM 650 computer (1953) ... but this RAM was actually a hard disk.

Actually it was a drum. No moving arms at all, but some tracks had multiple read/write heads to reduce access time.

Knuth's high school science fair project was to write an angular optimizing assembler for the IBM 650, called SOAP III.

Fukouka isn't particularly in short supply of access to water, it's just not convenient for them.

The region is humid and rainy for over half the year and it's only particularly dry for about a quarter of the year. And they have a comprehensive system for evacuating stormwater during the rainy season as well.

So I'd reason a guess that they have a waste water excess 1/2 to 3/4 of the year but still need the baseload capacity of the desalination plant for the remaining chunk of the year. And while you could probably switch over to plain seawater for the portion where you are running negative, it may not be worth the added maintenance/cleanup cost of having to deal with salt or brackish water for only a small portion of the year. So instead you just eat the losses for that window in exchange for the increased efficiency/lower complexity/lower operating costs.

SF Ruby held one of our meetings at Y Combinator because they are big fans of Ruby on Rails. Check out any one of Irina Nazarova's talks about the startups that are starting with Rails. Rails is having a resurgence. I believe it is because Rails is dedicated to the one person dev team, perfect for startups, as well as the Rails 7 shift away from the need for React, the Rails 8 shift towards full support for PWAs, and the Hotwire Native extension which makes transitioning from PWAs to native mobile apps easy.

Also, remember, Chime is just one of the Rails companies which went public recently.

Digikey pricing is designed around it. They give some really serious volume discounts: they'll happily charge $0.10 / unit when you're buying 1 while charging $0.002 / unit when you're buying a whole reel of 10.000. Similarly, they charge a $7 reeling fee if you don't want cut tape.

Combine that with a stupidly efficient order picking process, and I wouldn't be surprised if they basically break even on small orders.

You've got to remember that those small one-off orders are almost always for industrial prototyping. You don't need to make a lot of money selling 5 units for a hand-assembled prototype when you know you will be selling them 500 units for the initial automated run, or even 50.000 units for the final production run.

Additionally, there's a lot of value in being a one-stop-shop: they might not make a lot of money on small-quantity low-volume items, but if an engineer can purchase their entire BOM from you at once, she is unlikely to go looking for a competitor to save a few bucks on the higher-margin items.

Here's the thing, nobody trusts what the administration or statutes say any more so entities like postal services in other countries are interpreting everything as a worst case scenario, instead of relying on good faith and mutual cooperation as they would previously.

Here's a summary by a law firm:

Normally that would be sufficient, but now we have an executive branch that tries strategies like personally suing all the federal judges in a district because it dislikes some of their rulings on one of the president's signature issues. CEOs of major corporations are literally giving the president lumps of gold to decorate the oval office. So you'll have to forgive me for discounting the value of legal opinions in general nowadays.

I completely agree that there isn't any legislation that will "fix this problem" (other than perhaps abolition of H1B).

If it helps soothe the feelings of those who think hiring managers are demon spawn out to get them, I can add, as one of those who spent a whole season this year doing basically nothing but conducting first-round interviews all day, to hire four open SWE seats, it's misery out here for us, too.

It was a mix of laughably unqualified people; people in India lying and pretending to be in the US ("Which neighborhood in NY do you live in?" - "I live by the Statue of Liberty"); people sending ringers to do their coding exercises for them including different ringers or two ringers at once (oops); and entirely made-up resumes (we have your resume from an application 3 years ago but your entire life history has changed since).

how i solved for this was reciprocal pinning so any node owns all their data (personal log) + whoever they follow (mutual follow reprocity) last x content (indices so its easy to get last n, or last since xyz) and so anyone can decide exactly what they keep or not on their node and thus share by simply following or not (maybe two level, so you can choose to not pin people you follow) heh, smt like that

anyways the idea is very much to do like bittorrent or kademilia but for social media posts i need to research more the fediverse before building anything tho

Idk about other jurisdictions but locally that doesn't seem to be something I see a lot of in probable cause filings. Typically there's a reason the police were called to a given location and a reason they're honing in on the person they want to arrest, and they don't really need to dig around in someone's data to find a reason to justify the request for a warrant.

IANAL, just some guy who gets bored and reads CaseNet. Yes, I am aware that this is not a sign of a healthy mind.

> And with outdoor places getting more and more rare/expensive, they’ll have no choice but to consume slop.

What does this mean? Cities and other places where real estate is expensive still have public parks, and outdoor places are not getting more expensive elsewhere.

They also have numerous other choices other than "consume whatever is on the internet" and "go outside".

I don't think anyone benefits from poorly automated content creation, but I'm not this resigned to its impact on society.

Super uncertain, and, if the effect exists, it's tiny --- huge numbers of people have been taking these drugs for many years. Meanwhile, we know with certainty that T2D can blind you, and we know mechanistically why that happens. If you're at T2D risk, NAION would be a really dumb reason to avoid GLP-1s.

The disconnect between academia and private is real and often bizarre.

I have a good friend that's a recruiter for a top 20 flagship research university in the US. Her line is always, "We're education. We don't do things like ghost jobs and ghostings." She'll then often tell stories where she and her colleagues do the exact same thing you hear in the private sector.

Recently she asked me if I thought it was ok to go ahead and fly a candidate out for an interview knowing the funding had just been cut. Her boss (in recruiting) wanted to anyway in case the funding was restored. Luckily the hiring managers refused to go ahead.

I used a bunch of models in conjunction:

- Midjourney (background)

- Qwen Image (restyle PG)

- Gemini 2.5 Flash (editing in PG)

- Gemini 2.5 Flash (adding YC logo)

- Kling Pro (animation)

I didn't spend too much time correcting mistakes.

I used a desktop model aggregation and canvas tool that I wrote [1] to iterate and structure the work. I'll be open sourcing it soon.

I'm not a native speaker so I had to look up what "ontology" means specifically, and what I got is : "The branch of metaphysics that deals with the nature of being. " (among other things)

I agree in that sense that physics does not do well here. I actually think physics _cannot_ do well here. Physics (and the "hard" sciences more generally) are good at describing what something is, and how it interacts with things around it. We "know" by assembling individual pieces of information that form a consistent model, then declare that model to be true. When a piece of information outside of that model arises, we then have to call that model in question.

I do not "know" the Earth is spherical from direct experience. I do "know" it from other indirect means - reading, measurements, images from space and so on. I do not also think that Asimov is saying anything about how we know what we know - he just talks about how "science is wrong" is not a true statement. Science is always approximately correct, but how approximate is the question.

So perhaps I'm missing the point entirely here, but I don't understand your distinction of "instrumentalist knowledge" vs other kinds of knowledge. If you say physics cannot explain my knowledge that I enjoy watching the sunrise - then absolutely yes. That is not it's realm. In the same way that physics cannot explain the history of medieval China to me. A common issue among physicists is to assume that this is the only way to view the world, and I disagree with that. There are many systems of knowledge, and each is good at certain things. Rejecting one as the "global" system misses the richness of other kinds of knowledge building.

You claimed Swiss post will continue to accept gift packages over $100, contrary to their press release.

Several people have explained that you are incorrect — Swiss and others are not accepting gift parcels over $100.

You then changed tack and said Swiss Post etc have the law wrong.

So what to you? It doesn't matter what details and uncertainties are in the law, it's resulted in most European countries setting a $100 limit, and at least Finland has suspended delivery entirely (even letters).

A couple of questions for tackling browser use challenges:

1. Why not ask a model if inputs (e.g. stuff coming from the browser) contains a prompt injection attack? Maybe comparing input to the agent's planned actions and seeing if they match? (if so, that seems suspicious)

2. It seems browser use agents try to read the DOM or use images, which eats a lot of context. What's the reason not to use accessibility features instead first (other than websites that do not have good accessibility design)? Seems a screen reader and an LLM have a lot in common, needing to pull relevant information and actions on a webpage via text

You mean this fixes the first order effect that penalizes domestic manufacturers, assuming correct information. It does not solve it, there's second, third, fourth, ... order effects. And there's no rule those are smaller than first order, in fact, they're almost universally more.

Domestic manufacturers are still disadvantaged by having to pay tariffs for materials used for the product, but not present in the final product. And foreign manufacturers still don't. If used in machines (and used up), used in mining (and used up), used in transport, used in energy production, ...

These costs are very large, especially because specific materials are often not available worldwide, or have large differences in quality due to availability of tiny amounts of additives for alloys or compounds. These things do lead to very large differences in quality, and thus in value. You can't model that as a government, it's just not going to happen.

There's no way to fully analyze an entire economic chain (especially when almost everyone involved has a financial incentive to sabotage you doing that correctly, and that includes foreign governments). You'd think this wouldn't have to be explained to either Americans or especially a supposed "defender of capitalism", but here we are.

> 3. Pointless. Explain something that is difficult to get to know, because it matters so little. While technically correct, the actual facts matter so little that they result in no realistic improvement of any kind, and no decisions are changed as the result of the new knowledge. Such as the age of Earth.

It's bizarre to even consider that investigating the age of the Earth is "pointless". Finding out the age of our planet and other celestial bodies matters a lot in astronomy! Understanding the universe is the opposite of pointless, it's fascinating.

Or did you mean something else?

> As true in psychiatry as anything else

Wouldn't we expect it to be more true the fewer objective measures there are? Like if a treatment is supposed to improve blood sugar, and we can measure blood sugar cheaply in real time... we should expect misaligned incentives to have diminished effect compared to something where there is less ability to objectively measure, such as pretty much anything in psychiatry.

it's even worse if you are an individual developer who wants to sign the products you're releasing on Windows.

Azure had an "individual developer" beta that lasted less than a year and is now closed... so you have to be able to prove your "business" has been around for three years. they're one of the very few low-cost options who support cloud signing... $10/month or $120/year is VERY reasonable compared to $300/year the other registrars want, PLUS the cost of an HSM you can't use from the cloud.

how are people doing signed binaries on Windows for open source projects? I bought a three year file-based certificate to kick the can down the road but those three years are now up.

I have built a custom "deep research" internally that uses puppeteer to find business information, tech stack and other information about a company for our sales team.

My experience was that giving the LLM a very limited set of tools and no screenshots worked pretty damn well. Tbf for my use case I don't need more interactivity than navigate_to_url and click_link. Each tool returning a text version of the page and the clickable options as an array.

It is very capable of answering our basic questions. Although it is powered by gpt-5 not claude now.

I think C# and .NET in general are excellent in 2025. It is not as popular with startups because:

- Microsoft and Windows only stigma. Most people don't realize how far the ecosystem has come along since .Net Core etc. People still think its living the era of "Windows only"

- Historical ties to Windows only database like SQL Server. Most people who have worked in C# in a corporate env. were used to it with SQL Server which is not free and requires a license. It doesn't compete well with likes of MySQL and Postgres even though you don't really need SQL server anymore.

I think these are the 2 biggest reasons. Personally, I think C# is amazing and would totally use it to build a startup if I had to.

This is why you set Trackpad speed to "fastest", and take advantage of the aggressive trackpad acceleration. When you move your finger quickly you'll easily reach the far side of the screen before your finger reaches the edge of the pad, and slow finger movements will still be precise

I think that’s a little extreme, but here is a balance sheet based explanation where it works.

The US just sort of randomly decided to tariff everything from people they don’t like anymore. Because of the randomness of these tariffs, they impact not only consumer goods but production equipment.

The justification for these tariffs is something along the lines of “let’s bring production back to the United States.” That’s likely a good idea (says the Canadian), but when they use that justification while simultaneously tariffing production equipment the same as consumer goods you have to wonder what’s actually going on.

With production equipment, you amortize the cost of that tool over the years of usage. These tariffs are not amortized, meaning they must be paid at import. That takes cash off the balance sheet, puts it into equipment and hits liquidity.

If I was wickedly powerful and really hated Americans, going after SMB liquidity would be the most convenient (and profitable) way to cause generational harm.

> And don't confuse liberals with far left

That's the whole point of using that phrase. It's meant to alienate and disconnect. The phrase originated by the left to make any conservative point of view seem alien and "far" away from reality. I'm glad that it can be spread around more evenly. After all, we don't want any one thing disproportionately affecting any one group, do we?

It's hard to tell honestly. I studied psychology for two years in uni, and I dropped out rather disillusioned about the field. Some of my least favorite aspects included:

- Acknowledgement by our professors that P-hacking (pruning datasets to get the desired results) was not just common, but rampant - One of our classes being thrown in limbo for several months after we found out that a bunch of foundational research underpinning it was entirely made up (See: Diederik Stapel). - Experiencing first-hand just how unreproducible most research in our faculty was (SPSS was the norm, R was the exception, Python was unused). - Learning that most psychology research is conducted on white psychology students in their early/mid-twenties in the EU and US. But the findings are broadly generalized across populations and cultures. - Learning that the DSM-IV classified homosexuality as a mental disorder. Though the DSM-V has since dropped this.

The DSM-V is still incredibly hostile towards trans people through a game of internal power politics and cherry-picked research. It's really bad honestly.

Though I do generally hold psychologists in high regard (therapy is good), I'm not particularly impressed by psychology as a science. And in turn don't necessarily trust the DSM all that much.
Show HN: I Turned a Claude Artifact into a SaaS – Lessons from an LLM Wrapper
by maxtermed | 2025-08-26 21:00:07+00:00
Earlier this month I was playing with one of Claude's "inspiration" Artifacts, a bedtime story generator (a React component that runs in the browser). I showed it to a mom I know. She said "This is nice, but it would be great if it could make my child the hero of the story and narrate it so we can listen together."

That offhand comment launched a 2-weeks learning journey from a simple React component to a full production SaaS.

This technical journey taught me that "just an LLM wrapper" is like saying a restaurant is "just a kitchen." Here's how I built it:

Stack: FastAPI + SQLAlchemy + Auth0 + Stripe + OpenAI API

- Multi-step wizard flow with session management - Background audio generation with OpenAI TTS - User auth, subscription tiers, usage tracking - Rate limiting, input sanitization, secure file storage - Database migrations, monitoring, deployment scripts

The non-obvious challenges:

- Prompt engineering to make the child the hero of the stories - Voice selection and prompts to find a tone that doesn't terrify kids at bedtime - Session state across wizard steps without losing progress - Handling OpenAI API failures gracefully - Storage for generated audio files - Making it parents and grandparent-friendly

Claude Code helped throughout, as a senior engineer to bounce ideas off and to write quite a bit of code. I reviewed, understood, and sometime rewritten every block of code. The learning was the point, in this case.

The humbling realization: Yes, it's "just" an LLM wrapper. But so is ChatGPT. The value isn't in the AI call - it's in solving a specific problem for specific people and package it in a user-friendly way. Parents don't care about tech stacks. They care that bedtime takes 20 minutes instead of 2 hours.

I am not a Trump voter, but here's my understanding of what they're hoping for, economically speaking. By devaluing the US dollar, American manufacturing becomes more appealing to other nations. I think it's generally believed that tariffs are a pretty lousy way to boost domestic manufacturing, but I think it might be an effective means of accomplishing the goal of devaluing the dollar. This devaluing shouldn't have any direct, negative effect on Americans when buying domestic (e.g. home prices, locally produced food), but will significantly reduce your ability to travel or buy imported goods.

Again, I'm not a Trump voter and I think this is the clumsiest, most dangerous way to bring manufacturing back to the US, but that's my understanding of what their goal is. I'm not even going to touch the Christian nationalist side of the plan.
