I think what Meta didn't realize (or maybe they did and ignored it) was that they were not pioneering the metaverse. They already existed on the platforms you just mentioned. I've never played Roblox or Second Life but I know kids and teens who live on Roblox and adults who live on Second Life. Those worlds _were_ their metaverses, and there was no reason to jump ship to another platform when they already had a digital life established. And meta just ended up making a shitty version of the metaverse anyway for the reason you mentioned.

It's not that the metaverse never took off — the popularity of Roblox and Second life (and other online social spaces) is proof that the metaverse was in demand. It's that Meta never gave people a reason to join their metaverse.

Note that I'm loosely defining the "metaverse" as any online world where the community is the point and people spend real money to "get ahead" in those worlds. Many MMOs can be metaverses in this sense. I've logged onto Final Fantasy XIV and saw people who logged on just to hang out at their friend's in-game house, not to play the game at all.

> Which is a very niche use case to begin with, isn't it?

My specific use case is yes, but there are a ton of microcontrollers running realtime tasks all around us: brakes in cars, washing machine controllers, PID loops to regulate fans in your computer, ...

Embedded systems in general are far more common than "normal" computers, and many of them have varying levels of realtime requirements. Don't believe me? Every classical computer or phone will contain multiple microcontrollers, such as an SSD controller, a fan controller, wifi module, cellular baseband processor, ethernet NIC, etc. Depending on the exact specs of your device of course. Each SOC, CPU or GPU will contain multiple hidden helper cores that effectively run as embedded systems (Intel ME, AMD PSP, thermal management, and more). Add to that all the appliances, cars, toys, IOT things, smartcards, etc all around us.

No, I don't think it is niche. Fewer people may work on these, but they run in far more places.
Levitation – Mobile agent manager for Google Antigravity (open source)
by gustavogb | 2026-03-11 11:51:14+00:00
Hi HN! I built Levitation (https://levitation.studio) – an open-source mobile interface to monitor and interact with your Google Antigravity agents while away from your computer.

For those unfamiliar, Antigravity is Google's agentic development platform where you can spawn and orchestrate multiple agents working asynchronously across different workspaces. The problem: these agents keep working after you step away, but you have no visibility until you're back at your desk.

Levitation bridges that gap. A lightweight client runs locally and connects to a mobile-friendly dashboard. You can:

• Start new tasks while you are away form keyboard
• See real-time status of all running tasks
• Get notified when agents need input or hit blockers
• Approve/reject agent decisions from your phone

Setup is very simple. Just start a simple process locally:
```
npm install -g levitation-client
levitation-client start
```

The client outputs a connection code – enter it at https://levitation.studio and you're linked.

Why open source: I wanted this to be auditable. The client runs on your machine and you control the connection. Also so that people can improve it with their own ideas or fixes.

Feedback more than welcomed, if this is useful for other people beyond myself I'll keep releasing new versions with new features.

At scale, yes. Because human males have significantly longer fertility periods than females, the specific adaptations of men who are healthier into later life can be passed onto offspring. The same applies to women who reach menopause while they're still healthy are able to continue caring for family without the risk of expanding the population, albeit for their offspring.

While human evolution is not predictive, it has selected for a wide variety of survival-associated adaptations beyond the mere individual.

During p45 they dropped the MOAB on Afghanistan. The name got stuck in my head.

I was making a lot of Jupyter Notebooks at the time. I would create several versions while narrowing down an algorithm or constructing the principle proof of concept code. When I finally arrived at an essential solution, I would make a single cell file that would write to disc. I named the file *-MOAF, Mother of All Files.

Some things don’t change.

Show HN: MoodPulse App – a simple app to track your mood in seconds
by powerwild | 2026-03-11 11:53:02+00:00
Hi HN,

I built MoodPulse App, a small app that helps you log your mood in seconds and visualize how it changes over time.

The idea came from wanting something simpler than most journaling or mental-health apps. Many of them require long entries or feel heavy to maintain daily. I wanted something that takes just a few seconds but still gives useful insights.

What it does:

• Log your mood with a single tap (with optional notes)
• Visualize emotional trends with simple charts
• Track streaks and weekly patterns
• Share visual mood charts with friends if you want

The focus is on speed and consistency — something you’ll actually keep using.

I’d really appreciate feedback from the HN community, especially on:

• whether mood tracking like this is actually useful
• features that would make it more valuable
• privacy expectations for apps in this space

Thanks!

Neither did I read all these pages nor did I pretend to.

> Neither the wikipedia page for the Didot family, nor for Histoire générale des voyages shows the Angzarr symbol, I've carefully checked on all the scans on these pages.

You have linked these two Wikipedia pages[1][2], implying that they confirm your extraordinary claims of how obvious and well-known this symbol is. I could in fact check within a single day that the symbol does not appear on any of the 15 images linked in these pages.

So unless you can produce evidence for your claim that "that symbol was used as a notation symbol in those star charts and azimutal maps?", it is quite disingenuous to expect anyone to take it seriously. Expecting someone else to read "thousands of pages" to confirm or deny YOUR claim makes it even less worthy of consideration.

If you do have actual, material evidence for your claims, everyone in this thread would very much like to see it.

I used Kate a note taking app synced with syncthing for a while. Using only md files. I had another md based app on Android that worked similarly.

Kate has a decent file browser for hierarchy and it'll stay in place and not return to a weird default path when you close it. And as you said, very fast to open and use.

For one off Notepad like things I like Mousepad especially because it has the Notepad++ feature of being able to save a session without asking you whether it should. Featherpad is also nice for this kind of use.

> Just to also play the devils advocate, why SHOULD women be having children earlier.

Lower prevalence of complications, lower risk of death, lower risk of birth defects.

> Its very much a very personal choice in their own freedom.

We don’t disagree.

> I don't think this should be a political take at all. In this decision there is nothing any Government should have a say in.

Unfortunately, Americans don’t live in that world. The government makes decisions that impact the health of pregnant mothers and children all the time.

I think that's super common among technical founders (really, everyone).

But I'd gently reframe the problem. It's not really "building vs. marketing"; it's "building vs. distribution." After all, what you're talking about is getting more people to use your products. For technical products, that looks a lot like building: a thoughtful README, great documentation, spending time in communities where your customers are and both listening and helping. And, in the process of doing that, if there's an opportunity to pitch what you're working on, then pitch.

Don't worry about building complex "marketing systems" right now. Just get out there and help people in the communities you're trying to serve, and learn from the way they frame the problem (take careful note of the language they use to describe their problem...flip that around and turn it into your website copy!)

I wrote up a guide for exactly this situation: https://strategicnerds.com/blog/the-indie-developers-guide-t.... I also wrote a book on technical marketing that you can see on my blog as well. (see, that's me helping, then gently pitching)

Also FWIW, I am not a believer in automation. Yes, automation for optimizing ad spend and fixing SEO/AEO site issues. That stuff is great. But automating social media is a terrible idea. You just come across like a bot. Speak like a normal person and, truly, have fun with it. You're connecting with teh people you're trying to serve!

> If you contact Anthropic's sales team and set up monthly invoicing, there's evidently no fixed spending limit.

I don't think thats a smoking gun either, for a start we don't know if the pricing would be the same as you'd get credit-funded, but also a monthly invoicing agreement is closer to their fixed plans (you spend X per month, regardless of usage) than pay-per-use API credits, which may not be profitable.

Not that thats a smoking gun either, I can see it both ways

Confirmed. I wondered if it was a hardware hacker, as I've built a couple x0xb0xes from kits, but it was not. I guess this is where we are? I mean, 'we' that doesn't include me, 'cos I have x0xes and can do stuff with them.

As a reference for what 303s are actually like, early Plastikman acid/minimal tracks often have really intense 303 elements. The filter's characteristic and can have enormous resonance and sonority, but the ability to combine that with accents and produce wild dynamic effects is something you don't find in other synths.

Firstly, the original comment was about UI rather than aesthetics. Secondly, as with everything else in Emacs, you can customise the appearance however you want. Those screenshots are from vanilla Emacs which is admittedly rather ugly. Most people heavily customise, or use an Emacs distro like Spacemacs (https://www.spacemacs.org/) or Doom (https://github.com/doomemacs/doomemacs?tab=readme-ov-file) which have more sensible default appearance configs.

You can’t trade oil in any currency off the bat. It’s a complex market involving globe spanning logistics and geopolitics.

But I’ve personally traded oil in euros and know people that trade it in pounds daily. The yuan negotiations were complex because China wanted to get the currency controls set right so that it didn’t destabilize their peg while the saudis didn’t want get stuck with the worlds most illiberal currency.

This week India went back to trading for oil in rupees with an American global adversary at the behest of the US president.

The gulf states bargain on security was a boon for them and the states, but again the correlation was reversed. The Americans provided security, a willing and ravenous market for the goods and a stable liberal currency when few others could.

Yeah I really would like to know how many bots are on reddit (and on particular subreddits/threads) and also how many are here!

The interesting thing though is that the bots are just cheaper versions of real human influencers. So nothing has changed aside from scale (and speed) - the underlying mechanisms of paying for word of mouth is the same as it's been for a long time.
Show HN: Jottit – Publish in seconds, reviving my 2007 project with Aaron Swartz
by simonbc | 2026-03-11 11:57:42+00:00
Aaron Swartz and I built Jottit in 2007 as a really simple way for anyone to make a page on the web in seconds. You just typed something, clicked a button, and you got a page on a secret URL. It went offline years ago.

I've now rebuilt it from scratch. It's basically the same idea, but even simpler. Go to jottit.org, write markdown, and you have a published page. Claim it, pick an address, and you now have a feed of your pages at yourname.jottit.org. There's no signup to start writing. And no JS on public pages. You can export your writing when you want.

Jottit is free and open source. It's not a startup, just something I really wanted to exist again.

Maybe in the first 10 years of your career, after that you totally have the skills needed to create value from nothing - something no value extracting actor will ever be able to learn.

Might take a while but the milk surely becomes butter. His point is valid, maybe your pov is a bit clouded because his baseline is quite high (fame, money) but its not that different at a lower baseline. You bring 1.x to the world that fights over a deemed finite set with 0.x tools.

This is true, but the hacks are mostly in the C and C++ recipes as I understand it. Something like Rust or especially Go or Zig is far easier to cross compile.

I personally found cross compiling Rust easy, as long as you don't have C dependencies. If you have C dependencies it becomes way harder.

This suggests that spending time to upstream cross compilation fixes would be worth it for everyone, and probably even in the C world, 20% of the packages need 80% of the effort.

Thanks for the recommendation. I downloaded both social.pdf and noproof.pdf on my Kindle Scribe to read them carefully and revisited the discussions on EWD638 and EWD692.

It is very interesting to see how Sir Tony diverged from EDW: one is right in theoretical sense but cynical about human fallacies and how the society is heading towards more wasteful complexity, one is to live with it and stay optimistic.

You could just give the TLDR: by far the biggest improvement in the different generations of nVidia chips is calculating faster at half the accuracy. For blackwell vs hopper it was "double performance". By which they mean blackwell can calculate with NXFP4 at twice the rate hopper can calculate at FP8. Then go back generations all the way until you arrive at FP64, where we started. They even made a slight detour to "FP128".

Decide for yourself if this is a real improvement. You should probably consider that nVidia did not just give the new chips, but also demonstrated training a neural net with NXFP4.

It's not the only improvement, but it is by far the biggest.

I'm curious what you think about Iran killing 30,000+ protestors in the streets last month, going to hospitals to kill the injured, and continuing to review video footage to actively seek out and kill scores of 2+ million protestors?

Personally I find it strange that with all the vocal detestation of "Nazis" so many people aren't in favor of intervening when an undeniably fascist regime commits the largest mass murder since the early days of the Holocaust and has no plans to stop the killing.

Building Jottit with Aaron was one of the most satisfying creative experiences of my life. The original was wiki-style, more of a small site builder. This rebuild keeps the same spirit but leans into simple publishing.

In Claude Code, tool use means the AI can call external tools to perform real tasks instead of just writing text. For example, it can read or edit files, run terminal commands, search through a codebase, or check Git changes. The AI decides when a tool is needed, runs it, gets the result, and then continues the task using that information. This makes it work more like a developer interacting with your project rather than just a chatbot giving suggestions.
by wongarsu | 2026-03-11 11:59:08+00:00
I take "every character" to mean "anything that was represented in a reasonably common pre-unicode code page or character encoding, as well as anything that might come up in OCR output of text documents".

Emojis obviously got in from Japanese character encodings, and imho the world is off better for that. Though many of the extensions of the emoji set really don't seem to get what emojis are used for. Similarly, chess and shogi pieces as well as symbols from Western playing cards go in through previous encodings, and domino tiles got accepted based on being conceptually similar. A bit questionable imho.

On the other hand the Azimuth sign seems to satifsy the "would appear in OCR scans", based on being published in font catalogues. Even if nobody has come forward with a book it appears in, I don't think they made and advertised lead type characters for fun. It has to have had some use in printed publications of some type (probably scientific, from the surrounding context)

You must be new here.

But seriously, I think the level of discourse has gone down considerably on HN in the last few years. I know people always say this in their forum but I think it's true.

For instance, you'll see a post about GPT. Top comments are often "I use Claude", completely irrelevant. And then when [political thing happens] you get these passive-aggressive submissions with a lot of upvotes "how to switch to Claude". It's all just so exhausting.

I kept running AI coding agents with full filesystem and network access,
and no way to review what they did before it hit my system. Docker isolates
but doesn't govern. So I built envpod.

Every agent runs in a pod with a copy-on-write overlay. Your host is never
touched until you explicitly commit:

$ sudo envpod init my-agent --preset claude-code
$ sudo envpod run my-agent -- claude
$ sudo envpod diff my-agent # review every change
$ sudo envpod commit my-agent # apply to host, or rollback

Also: encrypted credential vault (agent never sees raw API keys), per-pod
DNS filtering (whitelist which domains the agent can reach), action queue
(irreversible ops wait for approval), and append-only audit trail.

Single 13 MB static Rust binary. No daemon, no container runtime, no
dependencies. Warm start in 32ms. 50 pod clones in 408ms. Tested on 9
Linux distros.

41 example configs for Claude Code, Codex, Aider, SWE-agent, browser-use,
and more.

Can you name even a single large company that wasn't created by the state? And yes, maybe created means "picked up a tiny company and made it big", I'm treating that as the same (ie. Amazon)

Also the whole internet started as a military project. The big reason, especially when it comes to Silicon Valley's tech is that people just don't want it until they can see what it does.

Exactly, I 100% agree, and IMO toolchains should default to assuming fast misaligned load/store for RISC-V.

However, the spec has the explicit note:

> Even though mandated, misaligned loads and stores might execute extremely slowly. Standard software distributions should assume their existence only
for correctness, not for performance.

Which was a mistake. As you said any instruction could be arbitrarily slow, and in other aspects where performance recommendations could actually be useful RVI usually says "we can't mandate implementation".

As a 2018 Tesla owner I strongly disagree with the idea that Elon's got a track record of success. The Model Y was their last successful product and it's just a stretched Model 3. FSD is not there. Robotaxi is an embarrassment. Cybertruck failed to deliver the gigacasted exoskeleton and shipped at double the original price point. Tesla has lost its way completely.

We absolutely need more investment in renewables and proven nuclear. But it is not only about this, more high-voltage inter-connections are needed. My understanding is that there is an EU initiative on this, just can't find the source right now.

Regarding nuclear, how much money did the ITER member states dump into something that is always 10 years away? That money could go into solar/batteries or fusion.

The ZSTs are unit types. They have one value, which we usually write as just the type name, so e.g.

struct Goose;

let x = Goose; // The variable x has type Goose, but also value Goose, the only value of that type

The choice to underscore that Rust's unit types have size zero is to contrast with languages like C or C++ where these types, which don't need representing, must nevertheless take up a whole byte of storage and it's just wasted.

But what we're talking about here are empty types. In Rust we'd write this:

enum Donkey {}

// We can't make any variables with the Donkey type, because there are no values of this type and a variable needs a value

This is overly pessimistic. Prompt injection can be largely mitigated by creating a protocol firewall between agents that access untrusted content and agents that perform computation: https://sibylline.dev/articles/2026-02-22-schema-strict-prom...

I'm working on an autonomous agent framework that is set up this way (along with full authz policy support via OPA, monitoring via OTel and a centralized tool gateway with CLI). https://github.com/sibyllinesoft/smith-core for the interested.
