So far the XR applications I use the most are applications I've develop that have multiple windows floating in the air for classification tasks where there is a lot of clicking and not a lot of typing and a low key "minority report" UX is great -- these started out as ordinary web applications that "just worked" in XR (I might run it in passthrough mode or in a home world) and got a few tweaks to improve the XR experience.

Before I got addicted to Arknights I was playing a lot of Beat Saber, I really oughta get back into it. I've enjoyed games like Asgard's Wrath and Angry Birds VR and have a huge backlog of them to play but I also have a big backlog of flat games to play.

The thing is VR worlds can't be too crazy because people don't like motion sickn ess, I've learned how to suppress that reaction in almost all situations and instantly trust what my body is telling me and not my eyes when it gets bad (falling down in the real world hurts) but I'm a software developer who makes a living by accomodating myself to machines more than anyone else on the team.

One thing I think about is how the people in video games usually are in a much worse situation that me, say Arknights or Sword Art Online or Freedom Wars. Maybe it is a consolation that you have a bunch of girls following you around or see a lot of colored-pencil style CGs of kemonomini, furries, scalies and such.

Notably the GFX capabilities of current VR systems are not so good meaning (1) successful worlds are cartoony and (2) it takes a lot of development work if you want better GFX. The Horizon Worlds vision of an authoring tool for ordinary folkds to make little imitations of the real world is dead in the water. Some breakthrough that makes things like this

Show HN: Best JSON Comparison Tool
by sourabh86 | 2025-09-03 16:54:36+00:00
Hi All,

For the lack of a clean, accurate and feature heavy json comparison tool out there. I made jsontoolbox compare tool.

This is the only tool that- - does real time comparison - shows JSON path dynamically as you navigate the json - allows type/paste in, import from file or drag-drop 1/2 files in the editor to compare - lets you choose if you want sync-scroll or not - sorts both json (only)if you like to see a sorted diff - lets you swap both json - lets you download each json separately with a custom file name - works completely on client side - has no ads - has dark/light mode

It is also one of the best JSON Formatter/Minifier out there :)

I know there is a sea of such tools out there, but as a developer none were good enough for my use case. Please try it out and share feedback.

There is something I can't seem to understand in the relationship between technology and non-tech people / companies.

As a tech-savvy person and someone who relocated recently, I rely a lot on tech solutions for daily problems. When I was choosing my medical insurance company, I concentrated on one that has a good app and English interface. When I need a barber, I search Google Maps and look for barbers who have a website where I can book an appointment. Same for doctors, workshops, or leisure activities. And most of the websites are crap. It's some obscure reservation system, or a generic website with poor design built on Wix or something.

And from one side, I feel like there is an untapped potential here. Any good developer who can build and design a website, can just offer this to their barber or dentist. But on the other hand, I also understand that I'm not the only one who came up with this idea, so there must be a different reason why non-tech people / companies seem to neglect their digital presence. Could it be because they still think that digital presence is not important (and only tech-savvy people like me search for a barber on Google Maps)? Or maybe it's because most small businesses can't / don't want to pay a few thousands for a website and a Google Maps presence (but rather pay $39/mo for Wix), meaning that despite the fact that we are basically surrounded by tech 24/7, the general population still expects tech to be free, or nearly free.

If your business model relies on fairly draconian control over the liberties of individuals in ways that defy normal human social norms (like propagating and giving away plants), then its probably not the right business model. Not even just from a moral standpoint; its a losing business model.

Also, exerting control over a commercial cloning effort and trying to control personal use and propagation are totally different scenarios.

The reality is their business is just not going to be substantially hurt by personal propagation and use.

It's not a technical problem. It's a social, legal and business problem.

Computers are subversive. They have the power to not only wipe out entire sectors of the economy but also defeat governments and militaries. If you let people run software freely, they can give themselves the power to do things like block ads and copy artificially scarce data at zero cost, directly impacting the bottom line of corporations. And that's when they don't run cryptography, cryptocurrency and anonymization software to escape government control.

So these businesses and governments have every reason in the world to usurp control of your computer. They want computers to only run software that's been authorized by them, so that you can do nothing that harms their interests.

It's not your computer, it's theirs, they're just letting you use it, and only if you follow company and government policy. And it's not at all about your security against external attackers in general, it's about their security against you.

It's got nothing at all to do with "capabilities". It's got everything to do with putting you in digital shackles so that you are forced to live in a dystopian cyberpunk technofeudalist digital fiefdom as a serf who pays and consumes in perpetuity.

A lathe can't actually replicate itself completely. Specifically, a lathe can only make ways smaller than its own cross slide's stroke. It would also be impossible to make a typical lathe bed on a lathe, though you theoretically could design an unconventional lathe bed that is possible to make on a lathe, even if grossly impractical.

The real starting point for machine precision is rubbing 3 granite plates together.

Ah I'd love an astro conversion.

I've had a fun idea knocking around for a while for astro. These cams have a fairly accessible serial port, hidden under the thumb grip rubber. I think the 6D may have one in the battery grip pins, too. We can sample LV data at any time, and do some tricks to boost exposure for "night vision". Soooo, you could turn the cam itself into a star tracker, which controlled a mount over serial. While doing the photo sequence. I bet you could do some very cool tricks with that. Bit involved for a first time project though :D

The 6D is a fairly well understood and supported cam, and your compiler background should really help you - so really the question is what would you like to add? I can then give a decent guess about how hard various things might be. I believe the 6D has integrated Wifi. We understand the network stack (surprisingly standard!) and a few demo things have been written, but nothing very useful so far. Maybe an auto image upload service? Would be cool to support something like OAuth, integrate with imgur etc?

It's slow work, but hopefully you don't mind that too much, compilers have a similar reputation.

There is always a "better mousetrap", and there are those that continue to use the old one because they "know how it works and it's set up just the way I like it". And there are others that try every new mousetrap that hits the market. (and that's ok, not slighting either one)

I will say that I personally have never really gelled with VSCode no matter how much I try to customize it, it still is just a bit off. For me, it's like it's too much to be a simple editor like SublimeText or NeoVim, but not quite enough to be an IDE like IntelliJ or Visual Studio (full). It does just enough that I expect a bit more of it and it often fails to deliver. Right now I tend to just use 2 editors - one very simple one for viewing/editing text files and one IDE (currently IntelliJ) for coding in a project.

On topic - Zed is actually a really nice editor. It had some rough edges last time I tried it, but it's probably about time to give it another go.

The advice I've seen with delegation is the exact opposite. Specifically: you can't delegate what you can't do.

Partially because of all else fails, you'll need to step in and do the thing. Partially because if you can't do it, you can't evaluate whether it's being done properly.

That's not to say you need to be _as good_ at the task as the delegee, but you need to be competent.

For example, this HBR article [1]. Pervasive in all advice about delegation is the assumption that you can do the task being delegated, but that you shouldn't.

> Just that it's not an expectation, e.g., you don't expect a CEO to be able to do the CTO's job.

I think the CEO role is actually the outlier here.

I can only speak to engineering, but my understanding has always been that VPs need to be able to manage individual teams, and engineering managers need to be somewhat competent if there's some dev work that needs to be done.

This only happens as necessary, and it obviously should be rare. But you get in trouble real quickly if you try to delegate things you cannot accomplish yourself.

Even if whole-home RO is feasible from a money perspective, it's horrible from a water conservation standpoint.

The very best units with high pressure achieve something like 1:2 ratios. Meaning for every 1 gallon of clean water you get 2 of waste.

Clean water is previous and should not be wasted so casually.

RO is OK if it's for something very small scale, like a sink for filling up water bottles - but it should never be used for things like showers/tubs, appliances, etc.

I’m in the same boat. I spent a lot of nights for a couple weeks getting everything tuned just right, in the beginning. But now, several years later, it really doesn’t take much. I spend maybe 2-3 hours once every few months, and that’s usually just adding a bunch of features that sound nice to make my life better. I’ve easily gone 6+ months without touching neovim config, if not longer, because it’s unnecessary. It only matters if you want to further improve your editor
Show HN: Deep Researcher Web App, Node.js-Based (Open Source; MIT)
by maxim-fin | 2025-09-03 16:57:44+00:00
I made OS (MIT) "Deep Researcher" web app based on Node.js. The app searches internet or, if nudged, the scientific articles databases, then creates structured reviews with in-line citations based on user's request.

The app requires your own api key to run OpenAI's LLMs and the web search tool. The LLM vendor can easily be swapped for another but the web search tool substitution will require work.

I just read AndyKelley's comment you mentioned, and I can't find anything wrong with it; it's not even saying anything negative about Rust. It just observes that Rust spends more.

Is $100k/year a good salary? Depends. For a software engineer, no, since most software engineers make more. For a paramedic, yes, since most paramedics make less.

To know if $15k is a lot to spend on CI and a website, a great way to answer that question is to look at what peers spend on the same thing. Hard to think of many better peer comparisons for Zig than Rust.

Do people really need that with modern computers? My computer is 10 years old and I just restarted VS in the last project I was working on. It was about 4-5 seconds before I could edit the text, which doesn't seem long. And I have 17GB available memory. Anyway it doesn't matter because I just don't restart VSCode that much. I do open projects in new windows and those can get slow, but the slow ones are mostly just rust code with rust-analyzer overhead, and when dealing with rust, slow-opening projects are only the beginning.

I don't know, it feels like Zed popularity is just people chasing the latest editor hotness, a time-honored traditional programmer ritual to be sure, but still, just a ritual. And now it seems zed devs have to put AI in front of all other initiatives, probably because of the VC funding they took.

I could see not wanting to use VSCode for other reasons, like MS pivoting back to "be evil", but at least in my little bubble, performance is not one of them.

Interestingly, a lot of those characters are not Unicode characters: the aircraft motion, weather pictograms, mail, wifi, phone, the "computer science pictograms" such as start/stop/copy/paste/print/trash, and so forth. Specifically, these use Unicode's private use area at E000.

It was the standard warranty which makes me think there was a known flaw in those keyboards.

Interestingly, I got nowhere with phone support. The support person told me there were no keyboards available and didn't know when it would be back in stock. So then I contacted Dell support on Twitter (as it was known back then) and they immediately got back to me to find out what happened and arranged the repair.

My main issue with claude code is running multiple ones in parallel. I don't want to manually do all the git worktree stuff, I just want claude to handle it for me.

So if Zed automatically handles that (where there's a worktree per thread) I can see the appeal. Apart from that, I'm already using Tower to view the changes so I'm not really sure what the value here is.

I tried installing it, and got an error "can't load supported slash commands" – not sure what that means.

For example looping over the files in a directory can happen in a different order depending on the order the files were created in. If you are linking a bunch of objects the order typically matters. If the compiler is implemented correctly the resulting binary should functionally be the same but the binary itself may not be exactly the same. Or even when implemented correctly you will see cases where different objects can be the one to define a duplicate symbol depending on their relative order.

Getting two animals to fuck and genetically engineering a plant in the lab are… not quite comparable in required levels of effort. Even then, if you want semen from a Kentucky Derby-winning thoroughbred to try and build off those genes, it'll cost you. Or a purebred dog.

No one's putting in decades of R&D into something like this if they can only sell a few thousand for a single year before the big nurseries take over.

housing is definitely a thing -- arguably the largest / main use of a credit score.

clearances don't apply to the population on the whole -- you have to willing apply to a cleared role. and you're going to be spending the gov's money and handling secrets, it makes sense to see if they can handle said money, cuz if they can't they'll sell secrets

I've never heard of a pre-emplyment check requiring a credit score. sexually harassing a fellow employee and getting fired will not end up on your credit as long as you can pay bills, and even if you can't, the lack of bills is what shows up, not bad work behavior

We built SafeSpace® to solve a problem many employees face: - Employees don't trust internal reporting systems. And when they do report, investigations often lack objectivity. - There's no safe, trusted way to give leadership honest feedback without fear of consequences. - Feedback isn't a quarterly checkbox — it should be continuous, timely, and acted upon. - Following up on feedback is just as important as collecting it; without visible action, trust erodes.

Why current systems fail - Fear of retaliation, even with "anonymous” tools - Internal investigations carry bias - HR teams are overloaded and can't provide 24/7 support - Organizations miss patterns until problems blow up

Why humans still matter - AI delivers speed, scale, and instant support — but trust comes from human judgment, empathy, and accountability - Workplace issues aren't just data points; they're human stories - Independent investigators can interpret nuance, assess credibility, and make fair, context‑aware decisions What we built - Multi‑channel anonymous reporting — web, mobile, QR codes, hotline — all end‑to‑end encrypted - Independent human investigators for unbiased fact‑finding - 24/7 AI coaching and counseling via our AskCyph™ AI infrastructure — instant, private, no third‑party data access - Pattern detection to spot systemic issues early - HR assistant for instant policy and compliance answers for employees and internal HR

We believe trust is built when employees know: - They can speak up without fear — no retaliation, no career risk, no judgment - Their case will be handled objectively by real people, not just algorithms — human judgment where it matters most - They'll get immediate, confidential support — the moment they need it, not weeks later - We recognize HR can't be everywhere at once — and we actively partner with them to close those gaps, strengthen processes, and ensure no concern falls through the cracks

Lathes can certainly make cylinders, and a tube-based lathe bed is not a stretch.

A lathe can't replicate its own assembly, of course. It can't seat the spindle in the constraint bearings, for instance.

A CNC (without the word lathe) can make most of itself, and possible all. Nope: certainly all, if two of its dimensions fit within its work volume.

I forgot the beaten path. I wondered where the porn was, like where is all the baseball( both insipidly boring), and then my boss did a web search for gramophone and there were only a few results, but banging rocks together? Millions. He looked for something related to goats and then I had to reload his machine from scratch. ( Dropper+payload) Like he blew a transmission.

Oh I remember that - the times that Mozilla and Firefox spawned some interesting stuff. There was Sunbird - standalone XUL calendar app before it was reincorporated into Lightning and ended up as part of Thunderbird. Flock browser that embraced Web 2.0 and allowed to connect to various services. Mozilla Prism for web applications - kinda like Electron/CEF. Firefox OS (Boot2Gecko) for phones, tvs and tablets (I'm still using its ringtones on iPhone). Mozilla Persona - similar to OpenID but never got that much attention (my ISP even for a while tried to be an OpenID provider). Mozilla Raindrop that tried to accumulate various messaging services within the browser with CouchDB and own interface. And Instantbird - multi-network messenger that used XUL and libpurple. Joost - P2P internet tv application which was awfully sluggish, couldn't keep connections up to various "channels" but I enjoyed watching cartoons from 20s and 30s when these could load.

Keystatic[1] is awesome. It's local-first by default and made for static site builds, so you can keep costs low by not using a server.

I've used it alongside Astro for both my personal blog[2] and two company sites[3][4]. It's worked amazingly well each time.

The irony being that Apple’s WebKit requirement on iOS is literally the only reason the web isn’t a Blink monoculture today.

The only browser that isn’t iOS Safari or based on Blink that has >1% market share is Firefox with 2.25%.

https://gs.statcounter.com/browser-version-partially-combine...

Without iOS Safari, Blink would have a greater market share than Internet Explorer had at its height. People’s “choice” would be between Blink, Blink, Blink, and Blink. I’m not sure why somebody whose job it is to work on Blink can’t see the problem with that.

We’ve seen a web monoculture before; it was terrible for the web and took years to recover from. Let’s not do that again.

How's it like working with schools/universities as a startup? I've always heard edtech can be a slow, bureaucratic sales cycle (and maybe not a high willingness to pay?).

I know a few different companies who ultimately moved out of the education market completely or just try to leverage their education traction as a beachhead to other markets. It sounds like you're focused on the education market - what's your take?

I just installed it on my EndeavourOS box. I opened it, it asked my which theme I want. I couldn't click, and suddenly it went into unresponsive mode. A minute later I killed it and uninstalled it.

I keep trying this editor every few months ever since it was announced, but I always have similar experiences. I remember once I managed to start actually editing something before the GUI started to disappear.

But hey, it has AI.

I think you are greatly underestimating how hard it has been, historically, in the US, to be a minority, politically active, or in legal trouble. Note that in the Cold War, many people, especially minorities, were indefinitely imprisoned with show trials (e.g. Mumia Abu-Jamal, Assata Shakur, Leonard Peltier) or extrajudicially killed (Martin Luther King, Jr., Malcolm X, Fred Hampton, Marsha P. Johnson, the victims of the MOVE bombing) because of being politically active.

I agree with you whole heartedly that scrutiny on a business should focus on the offerings of the business.

As for whether I’m an exception — maybe. Subjectively I think I am because I perceive myself to be putting more into the “business of business” than most other business owners I know, but I also have a bit more time. The services my business provides benefits from heavily cross linking service, sales, and event/auditable data. It fits cleanly into out of box sales processes that business software assumes. When we adopted our ERP we just changed our processes instead of butchering the software. What we actually offer is, to a large extent, set-it-and-check-on-it.

I would think that is a great luxury in a way. I don’t have to do back breaking labor to make a delicious batch of croissants for the masses every day. I’d rather the croissants be tasty than the bakery’s books be perfect. As long as they’re doing what they need to stay in business.

I did have something specific in mind when I made my comment about “how hard can it be?” I think I was painting with too broad a brush. When I typed that I was recalling the FinCEN BOI filings. All of two or three pages of an online wizard asking for all the same information most secretaries of state require, and such a disproportionate outrage about even having to do it. From peers in the business community I heard a lot of “this is too complicated!” Having read the FinCEN documentation on BOI, it definitely sounded way more complicated than it ever was to complete.
