I hate to doubt studies, but with advice like: "Invest in a zippered fabric bag and ask the dry cleaner to return your clothes in that instead of those thin sheets of plastic." I am doubtful. I assert that the number one source of microplastics in a house will be clothing. Your "lint trap" in a dryer? Largely microplastics.

Dust in your house? Again, largely made up of fabric fibers. Which are increasingly plastics. Especially so if you have a carpeted house.

I'm not fully against some of these ideas and studies. And I am all for reducing our exposure to microplastics, where we can. But folks largely ignore the microplastic lining in cans, thinking they are avoiding that plastic bottle. We seem to have done a great job of avoiding large plastics in the fear of microplastics. Meanwhile, folks have very little intuition on where the microplastics come from.

Long term changes are driven by day-to-day events. So, given that there are heat dome events every other summer now[1], they're actually correct. I think a reason that it might be hard for people to accept is that humanity is now, literally, the frog boiling in the pot. I imagine that Gen Alpha climate change deniers will be even more vociferous in their pleas that 100+ degree temps all summer every summer are actually normal.

That's a great suggestion, thanks! More or less it works like so, policy drafts are auto-generated by AI, you need to go through controls and provide the evidence. To support you better on this, we allow redoing their description with your context - and that helps a lot. On top of that we're able to generate some potential risks for you (as this part is also tricky to get started with). Now I'm completing business continuity planning (again - will get AI assistance) and then we need to add incidents - that should make us a complete platform and hopefully I'll be able to do Show HN post ;) Nonetheless - thanks again, we'll add how the process looks like to the landing page.
Show HN: Smart Switcher – A data driven window switcher
by aboveavuser | 2025-06-24 13:52:56+00:00
Hello, my name is Andrew. I'm an indie developer and I'm excited to release Smart Switcher.

Smart Switcher is a data driven window switcher aimed at improving the overall window switching experience. It logs data on your windows switching, then a prediction algorithm analyzes this data and uses it to predict which window you would want to switch to next.

When you need to switch windows, you press the switch shortcut to switch to the next predicted window. If this isn't the window you wanted, press the override shortcut to switch to the next most likely window. You can press the override shortcut as many times as needed until you arrive at your desired window.

This is an early release but should be mostly stable by now. Any feedback is appreciated!

Check it out here. https://aboveaverageuser.com/smartswitcher

Since I can't seem to add an edit to my post, here's a realization:

My 2035 prediction actually seems pretty optimistic. It was more than 20 years that we haven't seen any big AI revolutions, so 2045 would be more realistic.

And it seems our current AI is also not going to get us there any faster.

Grass lawns grow very well without any added water in most of North America. It will go brown in dry conditions, but as soon as it rains it comes back. Of course as a large continent there are deserts where a lawn cannot grow without constant watering, but the vast majority of North America is plenty wet for a lawn to grow.

A significant minority wants green grass year round and those people water their lawn. It is not a majority though.

Founder here. I was spending too much time trying to find the signal in the noise on Hacker News, so I built a personal AI analyst to do it for me and help me win back some time.

It scans HN throughout the day and uses a profile I wrote about my work and goals to find the few articles that are actually relevant to my projects. It's been surprisingly effective at surfacing high-impact ideas I would have otherwise missed.

How it works: You give the AI analyst a brief on your work, interests, and current focus. It uses that context to analyze new articles with Gemini, scoring each one on a 1-10 scale for relevance. For anything that scores >7/10, it generates a "big question" the article helps answer and a 3-step action plan.

I've opened it up for others to use. You can get 3 free personalized insights per day. The paid plan automates it and sends a daily digest to your inbox. You can check it out here: https://getfirstresponder.com/ai-news

It's also a Farcaster Frame, built with Next.js. The project is a work in progress by just me, and you can connect with me at x.com/1dolinski or talk to my AI at https://getfirstresponder.com/talk/1dolinski

Would love to hear your feedback

This post nicely doubles as an explanation of why current-gen LLM's tendencies to spray emoji everywhere is annoying. Replacing bullet points with rocket ships and hand symbols pointing at things and spraying the emoji everywhere, rather than highlighting the things the emoji are trying to decorate, actually tends to obscure the thing being nominally highlighted under the massively over-powerful colorful symbols entirely. The initial visual impression of these texts is "a splattering of colorful symbols, with some incidental boring text around them" and it takes time and cognitive effort to filter out the blaring color, which has no useful content in it, and get to the real content.

You seem to be the only one exhibiting disgust here, friend.

The main reason for my comment - though there's plenty more - is that a 38yr old and 22 yr old are literally a generation, and hopefully (for the older person's sake) immense life experience and maturity levels, apart.

I'm late 30s and couldn't possibly fathom being in a fulfilling relationship with a 22 year old - unless I was only interested in her as an object to be enjoyed.

That this guy had interest in her says to me that he's woefully misguided/underdeveloped. And she/the "defenders" could surely see that as well.

This is compounded by just cold approaching her in public. If they happened to meet through some common activity and got to know each other and hit it off - which is how normal people go about such things - it would be a different story.

I feel sorry for the guy, and all those here who are defending him.

32/36 too.

Having very local/niche events (especially near the end, when there are lots of places to go wrong) makes it feel unballanced. If you wanted to make the game more strategic and less "gotcha," you might want to have all the events available at the same time, or have a "come back to this item" option that would allow the user more control.

On a related note, there are only about 40320 possible choice paths (8!), making it about as rich as tic-tac-toe (though the context certainly makes the player think more), far lower than something like Wordel's (26⁵)⁵. Adding more decisions might make people take more ownership of their wins.

We have created an iOS/Android app for expats and tourists in the Netherlands. As we are two people with limited capital, we are currently using Facebook and Instagram ad's but need more effective ways to promote our app.

Could you provide advice on:

Additional tools and platforms to use for promotion 1.Cost-effective marketing strategies, 2.Mediums that can help us reach a broader audience, 3.Any insights or resources would be greatly appreciated as we aim to increase adoption of the app.

As I mentioned, we don't have much capital to spend on influencers or ad platforms. Kindly do share your suggestions and recommendations.

> This morning, as we enter a forecast high of 102F real temp, and heat index up to 110..

ok that's hot. Being from Dallas, I usually poke fun at the NE when temps get warm there just like the NE pokes fun at the South when we get an inch of snow. However, 102 with humidity and heat index of 110 is hot no matter what. When it's that hot here i try to take off shoes/socks whenever possible and soak down my head and wash my face. A lot of heat is shed through your feet and head. But you reach a point where there's just no escape, once the concrete is heated up it takes weeks for it to cool back down. The feeling of a breeze only making it hotter instead of cooler is not pleasant, my sympathies.

edit: btw, i don't see how people in AZ survive, the temps in Phoenix and other places just seem incompatible with life. The usual reply is "low humidity" but the inside of your oven is low humidity too, i wouldn't want to live there either.

From a purely economic perspective its all the same whether you are paying for products or paying for people and whether your revenue comes for media or sales. Those cost/profit first concerns are entirely the wrong questions to ask though, because they limit available routes of revenue generation.

The only purpose of software is automation. All cost factors should derive from that one source of truth. As a result the only valid concerns should be:

* Lowering liabilities

* Increasing capabilities

From a business perspective that means not paying money for unintended harms, and simultaneously either taking market share from the competition or inventing new markets. If your people aren't capable of writing software or your only options are free choices provided to you then you are the mercy of catastrophic opportunity costs that even the smallest players can sprint past.

> But running Linux is fucking hard

Running Linux is easy. Literally everything is easier from installation to installing drivers (they're all in the kernel except Nvidia, which you don't have to worry about if you're on Ubuntu as it installs it for you), installing software, updates, upgrades...

The only difficult part is all the shit advice on the internet and the idea that you *need* certain software.

The filters used for this range from near infrared to near uv. We used 4 different filters in all (for this image, the telescope has more). In general yes to fully appreciate all the color information as a human we need to generate different color combos so our eyes can pick up different contrasts.

However, what we strive for is being accurate to "if your eyes COULD see like this, it would look like this". To the best our our ability of course. We did a lot of research into human perception to create this and tired to map the information of color and intensity in a similar way to how your brain constructs that information into an image.

Let me tell you, I did not appreciate how deep a topic this was before starting, and how limited our file formats and electronic reproduction capabilities are for this. The data has such a range of information (in color and intensity) it is hard to encode into existing formats that most people are able to display. I really want to spend some time to do this in modern HDR (true HDR, not tone-mapping) where the brightness can actually be encoded separately than just RGB values. The documentation on these (several competing) formats is a bit all over the place though.

Edit: I wanted to edit to add, if anyone reading this is an expert in HDR formats and or processing, I'd live to pick your brain a bit!

As an extremely happy Glove80 user (Sunaku's Engrammer layout for those curious), I will watch this keyboard's career with great interest. I can definitely see it in my future (the Glove80's were recent enough (first one a couple years ago, and one more recent for home use) that unfortunately it would be an irrational purchase to make now)

__BUT__ say I wanted to ditch a KVM switch for some reason, and set up a second workstation at home...

My one complaint for the glove80 is it feels like it was made for someone's hands that are __a little__ larger than mine (I do have some sausage stubbs), so the adjustable clusters are interesting to me! However, I do also have an Azeron Cyborg II at home, which uses a similar idea, the clusters on that __do__ adjust, but at the smallest adjustment its still kind of uncomfortable for me; any small-small-hand users have experience reports with this one?

This is a really good introduction and I appreciate it. When I was building my AI PC, the deep dive research into GPU's took a few days but this lays it out in front of me. It's especially great because it touches on high-value applications like generative artificial intelligence. A notable diagram from the page that I wasn't able to find represented well elsewhere was the memory hierarchy of the A100 GPU's. The diagrams were very helpful. Thank you for this!

This is subtle and a simple counting argument (definable means satisfies a finite formula, there are only countably many finite formulas, there are uncountably many reals, therefore there must be undefinable reals) doesn't work, because "definable in ZFC" is not something that is formalizable in ZFC and so the usual set-theoretic counting arguments don't work.

So it is in fact possible and consistent with ZFC that all reals are definable.

I often notice that Linux (and maybe some BSDs) can accommodate two extremes on the tech competence spectrum especially well: the least opinionated users may treat their computer as a black box and just enjoy web browsing / chatting / media with some help, while the most savvy can extract value from tailored and private setups (like stability of Debian or power of Nix).

At the same time, Linux on the desktop fails often for everyone in between: the learning curve is still higher (especially for people coming from Windows), and some very specialized professional proprietary software can be missing.

Luckily, as mentioned in the article, Microsoft tries to make the balance more equal.

Writing this as a person who has used Linux for the last 15 years with a 2-year break for macOS and back.
by gowld | 2025-06-24 13:58:58+00:00
It's even more extreme than that!

Take the (uncountable) set of Real numbers. Remove the normal numbers, which is almost all of them in the sense that the probability that "a uniformly randomly chosen real number is normal (and therefore also undescribable)" is 1. The remaining set of numbers, which has measure 0 in the Real numbers, is still uncountable, meaning that the proability of randomly choosing a describable number in that set is again 0.

I'm not sure how deep this chain can go. Google AI says "only 1 steps" but it's not admiting the case described in this comment.

You're stuck on the same logic loop of "You can't use nuclear because there isn't enough solar", when nobody said we should only use nuclear. OP wanted to know if solar would be sufficient for MN winters, and if not, what else would be required. He wanted a "Convincing analysis".

The sun doesn't rise above 30deg over the horizon, for weeks. (MN > 45deg latitude, and earth tilts away by up to 23.5 deg). It gets below freezing for months, sometimes below zero for weeks. Sometimes below -10F for days (although that's becoming less common).

These are legitimate questions.

We're not going to find common ground, that's OK. Let's just stop circling around each other and/or worrying about it. Cheers.

Apparently no solution that has gained traction, and no single solution that works everywhere. Source address filtering (BCP 38) got us part of the way, but it's difficult/undesired to do in data centers.

IoT devices (speculated to be used here) would have to have a solution upstream. Things like MUD (RFC 8520) have been proposed, but have problems too - developers need to be able to list all communications of their device and make that available somehow (MUD profile server). Some consumers will never do it on their own, and may want to prevent alerting a device manufacturer they have a device (think connected adult toy...).

Also given that IoT devices may never be updated by their owners, expect to see IoT botnet DoS attacks for years.

>I am totally against Python tooling being written in a language other than Python.

Cool story bro.

I'm totally against Python tooling being in dismal dissaray for 30 years I've been using the language, and if it takes some Rust projects to improve upon it, I'm all for it.

I also not rather have the chicken-and-egg dependency issue with Python tooling written in Python.

>A popular Python package called Pendulum went over 7 months without support for 3.13. I have to imagine this is because nobody in the Python community knew enough Rust to fix it. Had the native portion of Pendulum been written in C I would have fixed it myself.

Somehow the availability and wide knowledge of C didn't make anyone bother writing a datetime management lib in C and making it as popular. It took those Pendulum Rust coders.

And you could of course use pytz or dateutil or some other, but, no, you wanted to use the Rust-Python lib.

Well, when you start the project yourself, you get to decide what language it would be in.

It's ending, it's a good idea to work towards upgrading, but yeah there's no one magic date after which a wall collapses and viruses waiting outside your computer rush in.

The worse an outcome with an outdated product the more the vendor has to support it because it would harm them to let any version of their product become synonymous with security risk.

Cold approaching someone to ask them out - especially if they hadn't yet AT LEAST exchanged smiles - seems to be the sign of a deluded/misguided person. And even moreso with such an enormous - and generally creepy - age difference.

More prudent and effective would be to approach a group, chat with them, and build a rapport. Then see where things go.

Even more prudent would be to not be so utterly pathetic and desperate, and instead just focus on doing things that bring you fulfillment. And then meet people who also do those things, some of who you will just click with. And perhaps even romantically. There's no "approach anxiety" that way because there's no "approach" at all! Just live an authentic, contented life - that's what's actually attractive to people.

The problem is that most people do not live an authentic life. But there's nothing stopping them from starting today and endless options for it. But keep "dating" out of your mind - just go and connect with people, develop interests, skills, self confidence etc

This is amazing! Thank you!!

The quickfix window is so small, so I added the "-c only" option to make it the only window that first pops up. Then made it a function so it's easier to call:

``` vgrep() { rg --vimgrep "$1" | vim -c cb! -c copen -c only - } ```

$> vgrep "restore_tool"

Precisely because the average participant of this platform has as much in-depth experience in actually incorporating and running a company in different parts of the world as the average person on the street.

Netherlands, and the EU in general, are cumbersome to deal with regardless of all the "startup incentives" they've been pushing in the past few years. Compare the incorporation, maintenance and closure processes of a Delaware/Wyoming/New Mexico/Florida LLC with anything even remotely comparable in Europe (e.g. a BV/NV/SRL in the Netherlands) and you will quickly see why the US has become the world's center-stage for doing business.

For SourceHut Estonia and Romania would have probably been a better choices, as from my understanding, they are not investor-driven and do not seem to head that way, they are fully digital/remote, and they require disproportionally more infrastructure than office workers to operate.

However, when living in the EU one has to take into account various (frankly absurd) taxation laws that might ultimately prevent founders from incorporating their company in any of the neighboring countries. Hence it would be necessary to look at the details of the founder's circumstances to evaluate if incoporation in a different country would have made sense to begin with.

That said, I agree with the top rated comment [1] as for the broader topic of where to incorporate.

Love the idea, this is fun! Some feedback, assuming the creator is in this thread:

- I have a hard time understanding the score. What might make it easier is not allowing multiple tries - if you put it in the wrong place, it moves to the correct position and marks itself as a miss.

- Putting dates on the cards gives too many hints IMO. I think it’s more fun if you build the entire deck based solely on order, and then their dates show up at the end.

The market? The manufacturers or the people?

Phones that were biggest size/weight only six or seven years ago are now not even available anymore. Why? I cannot imagine that all(!) people want phones that now weigh at least 180g (most even 200+g) and have huge displays.

Do people need to play games all the time? I don’t. I just want a phone to support me with some helpful apps like train/bus timetables, play music, do a quick internet search, make a picture, do alarms and notify about things. Nothing fancy, and nothing where a really need a 7" display nor a 5Ah battery.

When my current phone (Samsung A40) will die someday, I will be very sad as there is nothing today even remotely comparable to the compactness and usefulness of this device.

Which are those? Other than Nordic EU countries, most other capitalist countries on the planet are doing worse than the US when you look at stuff like youth unemployment, housing affordability or birth rates, all things that show economic outlook.

Capitalism is bad sure, but so far it's the least bad system we ever had and the US is one of the least bad implementations. Capitalism got a lot of countries out of extreme poverty.

Look at South Korea if you want to see true dystopian capitalism.
