I've seen many people make 3D prints of their own brain.

Once, I heard a story where some company was trying to get MRI test participants, and if you agreed they offered to print your brain for you as one of the perks.

Turns out, they gave everyone the same brain, like they would just always use the same file when 3D printing it. Probably had a box of pre-printed ones in the back. Dishonest, but I guess how would you ever find out?

It’s not that simple, although taxation is a lever I see more governments willing to tug cautiously on in this crisis. I do think multipliers on low-density housing that’s not owner-occupied year-round is an excellent starting point, though, one that would really only harm a smaller subset of landlords while loosening supply in the short-term (1-5yrs).

Still, tax policy alone won’t solve such a complex issue. We need deregulation in matters of zoning, and increased regulation in terms of rent-setting (both amounts and lengths). We also need higher-density housing near transit stops, regulations on sales of existing homes with fossil fuel heat (gas and oil) that promote their proactive replacement prior to sale, stripping HOAs of authority to police familial genetics or relationships in household makeup (to promote more shared housing in existing developments), and so much more.

It’s a complex crisis that requires a complex solution.

Totally speculating but, the moat must be Chinese speaking employees with enough engineering background at company office. Chinese factories look open to any reasonable businesses so long both are pragmatic and both talks the same language anyhow, but East Asian languages and cultures are related or connected to nothing else so just maintaining good mutual understanding can be hard(and I don't think LLMs help that much).

That's not true, following your analogy, many posts had the actual clock photo with an added red arrow pointing to the hand! And you don't need much expertise to evaluate readability once your attention is focused on it, so no, you're not left in the same place even if you see a hundred more posts saying the opposite and posting all the 1-12 numbers.

Of course, you also have plenty of assessments like "bold" and "fresh" where your view is as fluid as liquid glass because, well, there is little substance behind them. But then this is no different from non-social media articles.

This is the sort of issue that I think exposes a very interesting paradox in the average person.

People are worried about seemingly extraordinary cruelty perpetrated against a cute animal (maceration of young chicks) but basically accept regular, banal cruelty against typical farm animals (the practice of eating farming and eating meat and eggs).

I personally think the cause is at least on balance positive morally for any given male chick, but it’s not so clear to me that it’s moral if this scales to the point that the industry may raise more female chickens to lay eggs with less resources/comfort/etc.

The people in office now were already old by the time the Internet and especially Mobile took off.

But it’s not like many young adults today who grew up with mobile phones understand computers either. At 51 growing up with computers in the 80s, I find myself explaining what I think should be simple computer concepts to both my parents generation and my adult children.

My 80 year old mom is not a stereotypical old person who doesn’t know how to use a computer. She is a retired math teacher and has actively been using computers since we had an Apple //e in the house running AppleWorks in the mid 80s.

When she was tutoring teenagers mostly as volunteer work after she retired, she had to teach them how to use Office/Gsuite.

> > Wait, so we can all agree that killing the male chicks is inhumane. But you think the solution, _to not birth the male chicks_, is just as inhumane?

> No, you are putting words into my mouth.

As an onlooking third party, I don't understand. You further say:

> I don't see much difference between killing chicks after them being born, or stopping them from being born in the first place.

But as far as I can understand it, that is the same thing.

> I did not prescribe an alternative, don't pretend that I have.

It was not supposed that you were prescribing an alternative. The words "you think the solution" were not introducing a supposed solution of yours; they were introducing a solution (the process discussed in TFA) about which you (appeared to) have a thought.

I've seen this many times before and it always presents Charles Wilson's aversion to "research" in a "haha what a luddite" manner.

You have to understand that Eisenhower believed that the military industrial complex was out of control. He brought Wilson in to help rein it in and reorganize the defense department.

The military and military contractors were conducting "research" in the form of doing chemical and biological weapons experimentation on soldiers and civilians without their knowledge or consent. Wilson was trying to stop that.

And of course many of the think tanks were trying to lead the United States into an offensive war against the Soviet Union, which Wilson and Eisenhower did not want or think was necessary. It's entirely probable that the only reason Bellman got funding to do this work at RAND was because they intended to use it for running their desired war.

Your cautious self awareness is a credit to you.

The “righteous rule” forbids “destroying the innocent”, the only real human right anyone has before Power. Those who do not accept this rule rape entire families from the gene pool to destroy all that they love in this world.

…and smart modern peoples as yourself would flag and remove any such saying so for its impoliteness, not to mention “lack of proof” as though the idea itself incomprehensible.
Ask HN: Will marketing be the future king?
by YesBox | 2025-07-21 15:11:13+00:00
I see a lot of posts covering first order effects from Gen AI for us programmers. I'm very curious to hear people's opinion on second+ order effects. Particularly for B2C.

"Gen AI" refers to the basket of modern AI/LLM tools in vogue. For this question, we _assume_ these tools will lower the barrier to entry and lower development costs.

I'm a business owner working in the video games industry. I don't use Gen AI beyond occasionally using it as a search alternative (IMO, this is a (but not necessarily "the") killer feature of LLMs. It might kill so efficiently that it could dramatically change how we interact with the WWW). [1]

One comparison I like to make is the PC gaming market versus the mobile gaming market. In the mobile market, the majority of the budget is not spent on the game. It's spent on ads/marketing because the constrained resource is not code/assets--it's people's attention. In the PC market, the majority of the budget is spent on product. It's still possible to successfully release a game with minimal marketing. [2]

Is Gen AI just going to push the development costs to marketing and ads? Or stated generally, do budgets shift to the most constrained resource?

Will marketing be the future king?

Signed, - Someone planning for the future

[1] If the WWW becomes partitioned fiefdoms, information will not flow as freely. Thus: more resources needs to be spent on marketing to breach the walls.

[2] There are some caveats: The product needs to be top notch and distinct. Some genres are over-saturated or unpopular.

[3] Bonus footnote: I am of the opinion that none of these tools will change the distribution of visionaries. Taste is something that takes many years to develop through obsessive consumption.

> The only people losing are the people in Detroit.

I mean, that's a lot of people.

Also, the company doesn't pay people less all around. They pay workers less. The c-suite still makes more, and shareholders, who never did any work for the company whatsoever, get paid more. Car manufacturers haven't substantially lowered prices in years; so there are people paying more to get a car made by people making less.

Someone requested clarification on another post, so here it is:

It's a native Win32 app, with a window of 320x180 pixels, which scales upwards as you resize bigger. By itself the program does nothing except read and run a specific Lua file located in AppData. Drawing to the screen is the main operation of the program.

The Lua API has a few built in modules:

- "image" for dealing with gpu images, which includes the screen

- "lpeg" so you can write a custom parser

- "asm" so you can compile and run assembly code from Lua

- "memory" so you can read and write to real memory addresses

It uses real memory:

All the APIs, including the assembly you write, can access real memory addresses. So you can write to 0x20000 and read from it, either in Lua or Asm, and it just works. And you get raw pointers as Lua integers that you can pass around, which lets you pass them through assembly and back.

The app has a few competing primary purposes:

- Learn or practice writing x64 win32 assembly

- Learn or practice writing a programming language

- Learn or practice writing video games like it's 1979

- Learn or practice writing programs that manage raw memory

I had someone send me their entire credit report. Luckily I am not a scammer and I deleted it for them. They sent me an Amazon gift card to thank me for not stealing their PII.

I get DoorDash order notifications, Uber notifications, etc

I am not sure how they signed up with my email as I never got a sign up notification

Part of this also is because email / gmail is not case sensitive Jsmith@gmail.com is the same as jsmith@gmail.com. I see a lot of Jsmith vs jsmith (like how I actually use my email).

Nothing is getting stolen from me but not sure how this is actually working for people.

>As written, this only applies to nation states.

if you're quibbling about legal definitions, your "nation state" is used incorrectly. A "nation" is a large ethnic group, for example the German nation, the Cherokee nation, etc. A state is geography that is its own political entity/country, for example the gulf states.

Germany is a nation state, the Cherokee nation is not a state at all. Netherlands and France are nation states, Belgium is not, its just a state. Austria is part of the German nation but it is not part of the nation state of Germany. Australia or Canada are states but not nations.

The goal is banishing any and all questions of what to download, what desktop, what apps, packaging formats, software stores, user accounts, backing up, all of it: run the browser locally, sync the data – and only the data – to the cloud.

That is not really popular in the open source world. Who finances the cloud, is it open, who can read or sell your data?

If you're interested in home automation it looks like Home Assistant has an integration (https://www.home-assistant.io/integrations/lg_thinq/).

There is also a project for the esp32 which allows you to control it locally from Home assistant instead of the cloud based integration (https://github.com/JanM321/esphome-lg-controller)

They're arguing with foreign countries. Meanwhile the federal government continuously working consolidate all data available under groups like DODGE or ICE or Palantir. Arguing to preserve a tech in a given situation but with other goals ... not sure the first part matters at that point.

> The best ratio of hens to roosters is about 10-to-1. Each rooster will have his "harem" of hens that keep him busy, and the hens will be content. Any more roosters than that and they'll fight a lot, and the roosters that don't have their own group of hens will hang around the others looking for a chance to rape them while their regular rooster is occupied or too far away. It can be pretty hard on the hens.

It seems like a sick joke of nature that a species that behaves this way wouldn't also naturally be born in a similar ratio. I wonder if they're like that in the wild, too....

Permits and licensing is a huge factor, most of the southeast didn't even have licensing boards until the late 90s. If you wanted to build a house you could just do it. Now it's functionally impossible unless you are capitalized enough to spend a considerable amount of time and money on the permitting and approvals process.

One of the reasons there's so much gentrification is that it's much easier for builders to take a falling down house and replace 99.99% of it than to get approvals for completely new construction.

I bought a flat in the Spanish property boom. It was empty a while with ~80% of flats in the area vacant, then I had a squatter, now kicked out. Now most of the property is occupied and the Spanish government are bringing in huge restrictions to ease the property shortage. These things go in cycles. The boom and bust isn't very efficient but there you go.
Show HN: I Built ChatGPT into Microsoft Outlook
by manzodale | 2025-07-21 15:13:21+00:00
Hi HN,

After building a Cursor-style AI tool for Microsoft Word (now being rolled out across several consulting firms), I kept hearing the same request: “Can you do this for Outlook?”

Apparently, a lot of professionals are still copy-pasting email threads into ChatGPT, then pasting responses back into Outlook.

So I built it: Cursor for Microsoft Outlook

I've seen it: It's gruesome, but I'm not sure if in-ovo sexed roosters have a better end, or if its just more palatable to watch.

Eggs take 21 days to hatch, in-ovo techniques work at 9 - 15 day post laying, depending on the technique used. Couldn't find any details on how developed the embryo is at 15 days, but 2/3's done feels pretty far along.

I am very happy that I actually tried to use new iOS 26. It is just couple taps away for registered developers. I think it is a very nice redesign.

But focusing on the 'glass' component is very reductive in my opinion, and shallow. It is much more about overall layout overhaul. I, for one, think it feels much more easy and modern, a welcome upgrade. I am a programmer, not a designer. Functionally it feels better for me.

Hey everyone!

I’m part of the team behind Submagic, and today we’re excited to launch our new API that lets you automate video editing at scale - think Captions, B-roll, Transitions, Zooms, and more, all done programmatically.

Until now, creators and businesses had to rely on manual editing or expensive tools to turn raw footage into captivating videos. With the Submagic API, you can:

- Upload a video (or trigger from Google Drive, Notion, etc.) - Auto-edit it with captions, b-rolls zooms, etc. - Receive a ready-to-publish short-form video - Trigger the whole thing via Zapier, n8n, or directly with an API call

It’s perfect for:

- SaaS platforms that want to integrate video editing - Agencies automating content repurposing - Creators building internal tools - Devs experimenting with AI video workflows

We're live on Product Hunt today! Come check it out, leave us some love, and see what the community is building: http://bit.ly/46lNp30

Happy to answer any questions, feedback is super welcome!

Thanks for your support.
Show HN: ColorParser – Parse any color format from messy text into clean panels
by marclelamy | 2025-07-21 15:13:35+00:00
From working years ago with Photoshop, then Figma and more recently CSS and Tailwind, converting color formats has always been a pain. You need the exact format, find the right website, deal with comma placement and right formatting, it's annoying... So I built colorparser.com over the weekend. Basically, you paste any messy text with colors in it, and it automatically parses them and creates separate panels for each color. I know most people will have only one color to convert, but it works with many. Then you just click on whatever format you need (RGB, HSL, hex, OKLCH, etc.) to copy it. The nice thing is it handles format variations - so `hsl(200, 100, 50)`, `hsl(200 100 50)` or `hsl(200, 100%, 50%)` all work the same way. When you visit the site, it automatically reads your clipboard and parses any colors it finds, which saves time. Everything runs in the client. Currently supports hex, RGB, RGBA, HSL, HSLA, CMYK, and OKLCH. Planning to add more formats and features in the future. It's free and open source. Thought some of you might find it useful. Works best on desktop.

I think there are some applications though. I remember PWMing a peltier element to cool something to more or less exactly 35°C. I didn't need to be efficient cooling, it just needed to be reliable under space constraints.

I am no hardware guy and I remember there was a giant heatsink despite the constraints. It was some kind of photosensor + lamp if I remember correctly.

I think there was also some software logic to reduce water condensing at something too cool compared to the ambient temperature.

The problem is that feedback is difficult to get without customers. Plus in many cases, the feedback of what people intend to do is not really helpful at predicting what they will do.

I'll go with an example from my past: We built a SaaS for freelance photographers to organize and distribute their images. People loved it. We listened for feedback and people loved the new features. But churn was always a bit too high to make this a truly great business. We asked for feedback and got various reasons, none of which turned out to be correct. Most of our churn was photographers getting frustrated with the freelancer life and either signing up for an agency or changing jobs. That's how I learned the hard way that you cannot succeed in a bad market. But from the outside, it wasn't obvious that this market segment would be bad. You need to "test drive" the market with a product to learn if it can sustain a business or not. And that's what many of those indie builders are trying to do: feel out an acceptable market.

I fly fighter jets in a simulator called DCS. When you get task saturated you can feel the time speed up and then slow down. Hearing the RWR scream "missile missile missile" at you slows down the seconds to a crawl as you yank the stick and pray you turned in time to out run it. Then time speeds up to a frantic rush when you are trying to operate the radar and not hit a mountain at the same time.

Human time sense is just so weird when you pay attention to it a little.
Show HN: Apple Watch app with haptic-guided breathing to help you meditate
by Jonovono | 2025-07-21 15:14:27+00:00
I've been interested in meditation for many years now. Worked at meditation startups, have done Vipassana 10 day retreats. I've been able to get into some pretty deep meditation sessions and those have always been nice for me. But for whatever reason, it always felt like playing the slot machine for me. I could never consistently get into the space.

Meditation kind of would come and go in my life.

Anyways, I stumbled across this guy on Youtube talking about HRV resonance meditation (i'll link him below, but i'm not affiliated). He talked about reaching this meditative state as being a back-loaded process which kind of clicked to me. A mental state that arises by preparing the physical body in a certain way. At the least, this was intriguing to me.

His method was pretty simple:

1. Keep the breath rate under 7 breaths per minute (BPM)

2. Always Make the Outbreath Longer (AMOL)

3. Take out all the pauses between breaths

What this does is induce something called HRV resonance, where your heart rate begins to naturally sync with your breathing rhythm. This balanced pattern helps activate the parasympathetic nervous system, which brings your body into a calm “low-idle” state. Once you're there, mental clarity and stillness tend to arise on their own, hence, back-loaded.

So I was trying it out and had some good luck but wanted a better way to play around with the BPM and in/out ratio of my breaths. I had an idea of making a Apple watch app that used haptic feedback to indicate when to breath with a nice bodily sensation you can pay attention too.

So it's pretty simple, you can pick the in/out and BPM and then it will give one haptic indicating to breath in and 2 when you can release and start breathing out.

Id love for feedback and curious if anyone else has success with this method.

* No subscription (just a small one time fee, if you want to try it but can't pay lmk)

* I'm not overly happy with the "Smart Mode" so any feedback would be great. I think it would be cool to make it so you can hook it up to a HR chest strap to get HRV and react in real time. For now its pretty dumb (and written by Claude Code)

* I'm still new to this but do plan on doing some experimenting with my chest strap

* I'm not a doctor ;p

My daughter was born in 2020, when my employer was going through big changes and the world around me was obviously in chaos. There were real opportunities to work long days and advance in our new parent company. Instead, I took every day of paternity leave that they'd let me have and tossed in some PTO for good measure. There's nothing like being able to spend all day learning your new baby.

I recently had an MRI in one of those full-body MRI machines.. and we went through two locked doors and they used a wand on me (like they have at airports) to scan my body, even after I answered that I had no metal anywhere in my body. There were 3 operators/nurses in the inner ring of all this, operating machines.. securing my limbs, etc.

So at least in some places, this is the SOP.

Yes, and it is very tiresome advice to see continually, especially when given to newcomers whose first instinct is to build a solid, useful app or service, and they're being steered away from that. The number of times I've read that one should put up landing pages, spend time socializing them, and only if there are enough signups to actually build something is rather depressing.

These folks are obviously playing a different game than I'm used to. But in my ~30 years at it, I can confidently say that taking the time to build what I feel are good apps, well-crafted, has provided immense satisfaction (I can at least look at a collection of apps, not landing pages), and has always developed or honed my skills, which has opened many doors. The marketing-first approach just sounds painful for someone who, like me, wants to be building things.
