1. A Gentle Operating System

I’ve been building OS Yamato, a poetic, lightweight web OS where data “blooms and withers” — inspired by nature’s rhythms.

Unlike conventional apps that hoard information endlessly, OS Yamato invites you to let go. Unless opened, data fades and disappears. This is not a bug — it’s a philosophy.

I’d love to hear your thoughts on this approach — technical or philosophical.

I really like the idea of things left untouched naturally fading away with time. I routinely think about all of the old junk I don't technically need, but keep around for some not-likely-to-happen moment. Would be nice to just wake up and realize I've regained gb's of space.

Very cool idea.

We externalize so much of our cognition, why would you want to give yourself digital Alzheimer's to gain space? Why is void space valuable over memories?

Notes, photos, emails from loved ones, legal documents are less important than unused hd capacity?

Or: this is a system that forces mindful consideration of notes, photos, etc. If you want them to persist, you must at least look at them once a year. No dusty boxes in the attic.

Thanks for the thoughtful discussion — I deeply appreciate both the support and the challenges to this idea.

OS Yamato doesn’t intend to replace traditional archiving. It’s more of a philosophical experiment: what if our digital space reflected the seasons of life — blooming, fading, letting go?

I agree that some data — like photos of loved ones — deserve lasting preservation. Yamato allows you to mark something as a favorite (♡) to keep it longer, but even those gently fade if untouched for a year. Not to erase, but to invite mindful curation.

This project isn't trying to be for everyone — it's just an offering for those who find beauty in impermanence.

Always open to refining the vision — thank you for helping shape it.

Legal Documents is the big one here. I do think the philosophical notion is kinda cool and interesting, although I am too much of a hoarder to ever use this.

But legal document fading away just because you Haven look that them is just invitation for governments to fuck you over. Just a simple example in Germany taxation. If you do your own tax report then you usually do that 2 years after. So this year I did my taxes for 2023. Now the problem is with this OS all my data and receipts bills whatever that I have to send to the government for my tax report would be gone because why would I open it before I need it.

I agree as an art project of some sort.

My version of this would have agents that would categorize, collate and clean. Keeping the the habital spaces clean, perhaps showing things I should see. It might find things that are important (like tax documents, receipts, etc) and make sure that they are findable and archived properly.

I do find it very self centered in a way. Artists produce a lot of work, but to keep it from disappearing they are required to groom it with their attention? It leaves nothing for the future.

Yamato is a nihilistic aesthetic.

Thank you again for your perspective — it’s very thoughtful and appreciated.

While OS Yamato embraces fading by default, not everything disappears. For important items like notes, photos, and contacts, I’ve made it possible to export and download them locally at any time.

The idea isn’t to lock you into loss — but to invite gentle curation. You can always choose what to keep.

This balance — between impermanence and intention — is what I’m exploring here.

Your information lasting forever can be an issue when it's controlled by companies who exploit your data (and even short term that data can be exploited). If it's under your control than it can be quite useful. I can only see upsides to having old files and info; it is unlike too many objects which can cause issues in the physical world. That email I wrote 30 years ago in high school does no harm just sitting taking a few bytes of space. But if one day I wonder when I first read a memorable book and can find that the same email was part of a conversation about it to a friend, well, that adds depth and perspective to my understanding of it and, more broadly, my life and personal growth. To me, archiving is part of being more mindful.

Also, as a historian I hope future historians can find bits of text that we think don't matter at all but will help later generations understand our lives (i.e., their past and therefore themselves).

While this is not something I would probably use directly just due to technical limitations (incorrect hardware), I do really like the idea. I am constantly clearing out old stuff that I simple do not use, it is a good way to be. No need to carry everything around, everything gets voided in a long enough time.

Outside of the digital space, all the paintings I have done and everything I touch will be rendered null. Many will go to the rubbish tip either in my life time or very shortly afterwards. Don't try to cling on and drag this stuff everywhere.

Back to the OS however, hopefully you could allocate somethings to be manually exempt from the deletion but it would have to be done so that people must do it intentionally rather than just trying to avoid the issue of deletion. There are many one or two notes I keep with little bits and pieces I would like to keep, the rest of it is just noise.

Thanks so much — and I completely agree with your take on impermanence and letting go.

Actually, OS Yamato does support a kind of “favorite” (♡) to mark something you want to keep. But! Even favorites fade if unopened for a year

Because hey — if it really matters, you’ll probably open it at least once a year, right? (And if not… maybe it wasn’t that precious after all?)

Also, favorites are easy to find via sorting, and photos can be grouped in albums while memos can be organized with tags — so it’s not total chaos

It’s all part of keeping the garden tidy, not turning it into a museum.

That is a great middle ground. Keeps with the overall theme without compromise.

Really appreciate it — thank you!

OS Yamato is still in an early stage, so I’m actively looking for thoughts and feedback to help shape its direction.

You can even use it to casually chat with friends — so feel free to give it a spin and see how it feels in practice. Every small insight helps make it better

> if it really matters, you’ll probably open it at least once a year, right? (And if not… maybe it wasn’t that precious after all?)

This makes me wonder if you've experienced much loss in your life.

About twenty years ago, I lost my wife and child in an accident. It took years before I could look at photos without drowning in grief and even today, after lots of therapy, I can't look at too many before I'm overcome. These photos are the most precious item I own, and it would be devastating to lose them, but I do not look at them often or at every one.

I actually agree with the over all premise that the majority of things we save can be pruned, but there are things that just... are beyond this simplistic view IMHO.

I am sorry for your loss. I cannot imagine the grief. It must be very hard.

Reply suggestion:

Thank you for sharing something so personal. I’m truly sorry for your loss — I can’t imagine the depth of that grief.

OS Yamato is not meant to impose forgetting, but rather to invite reflection. Some memories deserve to last forever — and Yamato allows users to mark items they wish to keep. That said, I understand completely that not everyone wants to revisit things often, and that doesn’t make them less precious.

Your perspective is a meaningful reminder that digital systems should be gentle and flexible. I’ll carry that with me as the project evolves. Thank you again.

Thanks so much for all the thoughtful comments — I truly appreciate the range of perspectives shared here.

I’m still catching up on all the replies, but I just wanted to say: it's incredibly encouraging (and humbling) to see OS Yamato spark both support and critique. The goal isn't to make a "perfect" system, but to explore what mindful, seasonal digital spaces could feel like — and your feedback is helping shape that.

Will follow up more soon once I’ve read through everything properly.

That LLM readme is a big turn off.

"Is this another vibe-coded thing?" is the impression I get from it too, which is ironic given what it does.

To be fair, the author is Japanese. I imagine the LLM is translated from Japanese.

Totally fair — and thank you for the honest feedback.

I’m actually Japanese, and while I try my best, English isn’t my strongest skill. I do rely on AI to help write and translate at times.

Ideally, I’d work with someone fluent to help polish things. But for now, OS Yamato is a side project I build in the margins of a full-time job — so I’m doing what I can solo.

If the project grows, I’d love to team up with others who can help shape the language and communication more clearly. Really appreciate your understanding!

If you really want I could rewrite it to sound much better without the trademark LM quips in like 10 mins

That would be incredibly helpful — thank you! If you notice anything especially awkward or unclear in the wording, I’d love to hear it. I’m always open to learning and improving, especially as this project reaches more people.

I'll give it a shot this weekend.

Thanks so much! That would mean a lot.

I’m always trying to improve both the UX and the way I present OS Yamato in English. It’s a solo project, but thanks to feedback like yours, I can keep polishing and refining it step by step.

4. Philosophy & UX

Traditional operating systems emphasize archiving — keeping everything forever. OS Yamato flips that. It offers a seasonal, emotionally lighter, and more mindful digital space.

No addictive loops. No algorithmic feeds. Just calm tools for slow living.

A Personal Note

I’m not here to trap anyone in subscriptions. I don’t want you addicted to OS Yamato. I don’t want your data to sell ads.

I just want to build a gentle digital garden, where tech gives us space to breathe.

This is an early project, growing with every bit of feedback. Built solo, evolving daily.

2. Why Let Data Disappear? •In a world obsessed with saving everything, we rarely ask: Should we? •OS Yamato embraces intentionality and impermanence. •Notes, messages, and journals start as , blossom into , and wither into if left untouched. •Reopening revives them — forgetting lets them go. •There’s no pressure to archive or manage an endless inbox.

This system is inspired by mujo (無常) — the Japanese philosophy that all things change and nothing is permanent.

the Japanese philosophy that all things change and nothing is permanent

After what happened to them 80 years ago, you bet they don't want to remember their history.

As I understand it, the philosophy dates from centuries before that, and was inspired at least in large part by the frequency of earthquakes there.

The philosophy of mujo (無常) goes back centuries, long before modern history — it’s about the natural impermanence in all things.

OS Yamato isn’t about erasing memory, but encouraging us to reflect on what we choose to keep. Sometimes, letting go is part of how we grow.

Appreciate the thoughtful pushback.

3. How It Works (Technical Highlights) • Each item (message, post, etc.) has a lastOpenedAt timestamp. • Scheduled jobs (or lazy rechecks) determine expiration. • Opening the item resets its lifespan. • Visual transitions (→→) are animated via CSS. • Data isn’t hard-deleted instantly — it’s softly marked, and revived through interaction. • Download is always available. Nothing is locked in.

I keep hearing "web OS" a lot lately. Have people forgotten what "OS" means? "Website" or "webapp" if you must.

That’s a totally fair point — and yes, Yamato isn’t a traditional OS by any stretch. It doesn’t manage hardware or processes.

That said, “OS” here is a bit poetic — it’s more like a gentle digital environment, or a mindful space for everyday tasks.

Maybe it’s closer to a “life OS” in spirit — an interface for journaling, chatting, and reflecting, where forgetting is intentional and calmness is designed-in.

Happy to hear any naming thoughts though — it’s still evolving!

"gentle digital environment" sounds better than "OS", and is more accurate

Thank you — I really like that phrasing too.

“Gentle digital environment” definitely captures the feel more precisely. I used “OS” a bit poetically, thinking of it as a space that supports small, mindful digital routines — journaling, reflecting, and letting go.

Still evolving, so I’m grateful for the nudge toward clearer language.

Just use nixos with impermanence if you want this

True — NixOS + impermanence is a powerful option for developers. But OS Yamato is aimed at a broader audience — a calm, poetic space for reflection, not sysadmin workflows. It’s less about managing dotfiles and more about tending a digital garden.

That said, thanks for the suggestion — I really appreciate ideas like this that push the concept further.
