The club I mentioned above was just hosted out of a guy's house. The original group new each other through a comic book shop, basically the only place in town that sold manga back then.

The host was an air force officer that'd been stationed in Okinawa for a while and fell in love with anime there. When he came back to the states he got friends to buy and ship him laserdiscs of anime from Japan on a regular basis, and showing those to friends gradually became the club.

Fun enough we'd host lan parties pretty often too. This was back when you had to daisychain coax ethernet, and one person having to leave meant everything had to shut down for a bit lol.

In the pre broadband era there was this sort of local collaboration in a way that I miss, but I'm also not blinded to the negatives of that era. Like the anime club had some very enthusiastic loli fans that with the benefit of adult hindsight were way past the creep line and definitely had a chilling effect.

Lua has tail call optimization and js doesn't. For me, this is a dealbreaker for js.

Lua also has operational advantages compared to javascript. You can build it from source in at most a few seconds and run it anywhere that has a c compiler. The startup time is negligible even compared to a compiled c program so you can run entire scripts that do very useful things faster than most js engines can print hello world. There is also the benefit that in spite of what this article discusses, it is possible for most problems to write a lua solution that works for all lua >= 5.1. This is wonderful because it means if I stick to the standard library, the bitrot is essentially zero.

Calling into c is very straightforward in Lua, especially with luajit, which makes it superior to js as a scripting language (the node ffi api is quite painful in my experience and ffi runs against the js execution model).

Lua also essentially got lexical scoping of local variables correct from the beginning while js blessed us with the nightmare of var.

Of course Lua is far from perfect, but while there are some similarities, the differences are quite significant and meaningful.

i find it disappointing that whenever this issue comes up, the obvious solution is being ignored: montessori.

it solves both problems: integrating a diversity of children and allowing children to learn according their capacity and interest.

because each child gets to learn at their own pace, from the gifted all the way to intellectually disabled, all in the same class. (the term disabled feels wrong, but i am not sure what the correct term here is, i picked this one from wikipedia)

ironically, but in line with the title, maria montessori developed that curriculum specifically for disabled/special needs children. turns out what is good for special needs children also works for normal children.

and it would not be expensive. training a montessori kindergarten teacher takes one year. you don't even need a full degree, or it could easily be included in a degree curriculum.

How do you propose it's implemented though?

The two sides in this debate seem to be talking at cross purposes, which is why it goes round and round.

A: "We need to do this, however it's done, it was possible before so it must be possible now"

B: "You can't do this because of the implementation details (i.e. you can't break encryption without breaking it for everyone)"

ad infinitum.

Regardless of my own views on this, it seems to me that A needs to make a concrete proposal

The stunning revelation in the video was that Kurz tried using AI to write a script about Brown Dwarf stars. Kurz have a robust fact-checking process with multiple independent experts, and about 20% of the 'facts' in the AI script couldn't be verified by Kurz staff from the listed sources. When the script was given to independent experts, these experts identified the exact same suspect facts, which the AI seemed to have made up in order to fulfill the general expectations of the script. Kurz ultimately shelved the AI script.

Kurz later observed that another creator on YouTube published a well-edited video about Brown Dwarfs that received a fair bit of viewership. Only Kurz were completely horrified to find that it incorporated the very 'facts' about Brown Dwarves that Kurz had determined were AI hallucinations. It was clear that the other YouTube creator had used AI at some point in the process of script writing, but failed to identify and remove the hallucinations and the video was becoming a prominent source of public information about the topic.

I feel like these people have a fundamental misunderstanding of how human memory works. We have way better spatial memory than for words. The start menu is one of the better tools for that, because it can contain a lot of information (applications) based on where the user puts them and it's easily accessible. You don't have to minimize other applications, like you do if you want to access the desktop, and the start menu loads instantly (well, it did until Windows 11/before ads).

You're not supposed to "look" for where something is, you're supposed to know. Just like you're not supposed to look for the X in the top right corner of an application. You know it's there and you know that if you move the mouse into the corner you can click it (which is very infuriating when some UI design decides that the top right corner pixel does not count for pressing the X button). The start menu in the bottom left worked in a similar way.

> China is building, domestically deploying, and exporting solar, wind, batteries, and EVs so fast that the world will have no choice but to rapidly move towards net zero simply due to economics.

I can't help but read "we're going to produce and consume more than ever" and I really don't see how it ends in a good way...

Take transportation alone, 1.3 billion ICE vehicles to replace by EVs, there is nothing green about that. Not even talking about the absolutely massive mining operations we'll need to build solar and batteries. What about cement? Steel? Petrol derivate chemistry, medicine, fertilizers,...

And then what? We continue building and consuming more and more shit forever? Who believes this can be "net zero"?
Show HN: CodexLocal – Offline, Privacy-First AI Coding Tutor (WebLLM and RAG)
by FitchApps | 2025-10-07 18:01:55+00:00
Hey HN

I’ve been working on CodexLocal — a privacy-first, offline AI coding assistant that runs entirely in your browser (no servers, no tracking, no data sent anywhere).

It’s built with WebLLM and WebGPU, and supports RAG (retrieval-augmented generation) so it can be context-aware — even without internet access. Think of it as a local ChatGPT-style coding tutor, but one that never leaves your machine.

Why I built it Most AI coding assistants today are cloud-based — great for convenience, but not ideal for privacy-sensitive or educational settings. Bootcamps, schools, and dev teams often want to use AI without sending code or student data to third-party servers. CodexLocal aims to fill that gap.

Current MVP features ----------------- Works fully offline in your browser (WebLLM + WebGPU) Context memory via local RAG No login, tracking, or external API calls Works on Chrome, Edge, and soon Safari Light and dark themes

What’s next ----------------- File uploads for RAG context Offline model caching Classroom/enterprise deployment (commercial tier) NPM package / SDK for integrating into private dev environments

The ask ----------------- Would love feedback on:

Performance and model responsiveness in your browser Whether this kind of privacy-first setup would fit your org or classroom Any ideas for improving UX / RAG relevance

Try it: https://codexlocal.com

Demo video: https://www.youtube.com/watch?v=rnDmwW2x16s&feature=youtu.be Free for personal use, future commercial tier planned for enterprise deployments. Thanks for reading — feedback very welcome!

Rather than "pleading" for them to stop, wouldn't she have more success going after the ai content creation companies via legal process? I thought actors have the right to control commercial uses of their name, image, voice, likeness, or other recognizable aspects of their persona, thus if people are paying for the AI creation wouldn't the companies be wrongly profiting off his likeness? Although I'm sure some laws haven’t yet been explicitly updated yet to cover AI replicas.

The earlier up the product development stream you can place your product, the bigger share you'll have down the road. There's the saying about planning for 1 year, rice, 20 years, trees, 100 years schools. Windows is the leader because most kids grow up using windows in elementary school and blindly continue on. If you own arduino, maybe they start on ardunio, continue on to qualcomm products, and they're already trained in the qualcomm ecosystem before they've started engineering school. Adobe famously was very lax on closing Photoshop cracks in the early 2000s and trained up an entire generation on their product with great success.

Our last President was haunted by completely unverified claims of business ties with Ukraine. Someone in UKR clearly tried to buy influence via his son, but all the force of Fox News and the GOP together couldn't produce one single sticky-note worth of evidence tying it to any success.

Painting "armed invasion" as "Russian presence" is like calling "stabbing someone in an alley" a "medical procedure".

We get it; you love Mother Russia.
Show HN: Spaceflight-inspired pocket optical breath analyzer – 10Hz CO2/O2
by larichev | 2025-10-07 18:02:59+00:00
We built a pocket-sized optical breath analyzer based on an optical sensor for measuring CO2 and O2. It streams CPET metrics in real time (VO2, VCO2, VE, RER, Tv etc) for breath-by-breath analysis. Functional prototype based custom PCB, mobile app, and web platform are working.

Demo videos:

https://youtu.be/-DcvRPJJkj0

https://youtube.com/shorts/Ycy8wP4oW2o?si=W0n1Oyof7M37kdta

What’s different

Instead of electrochemical O₂ fuel cells and typical CO₂ NDIR modules (slower response, periodic replacement/calibration), we use non-consumable optical sensors tuned for breath-by-breath dynamics. Our CO2 channel samples at 10 Hz — roughly ~100× faster than NDIR sensors — and does not require an external pump, improving portability. Inspired by the optical, low-drift principles used in spaceflight instrumentation (e.g., Perseverance Mars Rover [1] and NASA PUMA projects [2]), our analyzer uses non-consumable optical gas sensors engineered for stability in harsh environments.

Early specs

Electronics: custom PCB with ESP32; BLE/Wi-Fi, USB-C, Accelerometer, Magnitometer, PMIC with shipping mode, OTA CO₂ sensor: optical IR, 10 Hz; (supports capnography for medical) O₂ sensor: optical, T63 < 2 s; low drift (< ~1%/year in lab conditions) Flow/Volume: low-inertia turbine (bi-directional), optical interrupter Measurements: in-flow, breath-by-breath Portability: device < 200 g + ~120 g mask (Hans Rudolph) Power: accumulator w/ integrated charging & protection; >4 h typical runtime Maintenance: no annual sensor swaps; no bottled-gas calibration

Who it’s for

Sport labs, pro teams, elite athletes/coaches, premium fitness clubs, nutrition and longevity labs; medical workflows later (post-regulatory).

Limits / open questions

Enclosure/thermal design, turbine inertia/lag at very low flows, CO2 calibration method, humidity transients, and cross-flow effects are active work. We’ll publish more validation data (and APIs) as we progress.

We’re bootstrapped (no external funding yet). Feedback from practitioners would help us prioritize the roadmap. Happy to answer all questions and brutal feedback welcome! We’re also looking for pilot labs / co-dev partners.

I think that enterprises and small businesses alike need stuff like this, regardless of whether they're software companies or some other vertical like healthcare or legal. I worked at IBM for over a decade and it was always preferable to start with an open source framework if it fit your problem space, especially for internal stuff. We shipped products with components built on Elastic, Drupal, Express, etc.

You could make the same argument for Kubernetes. If you have the cash and the team, why not build it yourself? Most don't have the expertise or the time to find/train the people who do.

People want AI that works out of the box on day one. Not day 100.

Hey - this is awesome. I've been working on a small local app like this to import financial data and present a dashboard, for the family to use together (wife and I). So yeah - great work here, taking control of your data.

I'm curious about real-time data, or cron jobs, though. I love the idea of importing my data into this, but it would be nicer if I could set it up to automatically poll for new data somehow. Does Timelineize do something like that? I didn't see on the page.

> (Side ask to people using Jujutsu: isn't it a use case where jujutsu shines?)

Yes! For the case discussed in the article, I actually just wrote a comment yesterday on lobsters about the 'evolog': https://lobste.rs/s/xmlpu8/saving_my_commit_with_jj_evolog#c...

Basically, jj will give you a checkpoint every time you run a jj command, or if you set up file watching, every time a file changes. This means you could recover this sort of thing, assuming you'd either run a commend in the meantime or had turned that on.

Beyond that, it is true in my experience that jj makes it super easy to commit early, commit often, and clean things up afterwards, so even though I was a fan of doing that in git, I do it even more with jj.

> I'm old enough to remember what it was like to deploy a Rails application pre-Docker: rsyncing or dropping a tarball into a fleet of instances and then `touch`ing the requisite file to get the app server to reset.

If this is what you remember, then you remember a very broken setup. Even an “ancient” Capistrano deployment system is better than that.

> What have you done in your own home? I’d be curious to know.

I've gotten rid of anything in my kitchen that I can that contains PFAS or is produced with PFAS or PFOAs. I use cast iron or stainless steel cookware, glass and silicone only for things that cannot be made of stainless steel. I've more or less eliminated plastics as much as possible from the kitchen. Unfortunately, I can't necessarily do that with food packaging, but even there when I have an option I will change brands or stores to buy things without plastic packaging, or paper packaging coated in PFAS/Teflon. Similarly to avoid PFAS and other chemicals in the production of plastics, as well as microplastics, I almost exclusively buy clothing made entirely from natural fibers.

Beyond that, I have a whole home water filtration system, and after that whole home filtration system I additionally run an undersink 5-stage RO system, both of which are NSF/ANSI certified (53 for the filter system and 58 for the RO system) to remove PFAS and PFOAs. I also go out of my way to find and buy products that don't contain added PFAS, because unfortunately PFAS are in many basic everyday household products like dishwasher detergent, rinse aid, laundry detergent, fabric softener, and the like. If you dig into this you will be disturbed at how many things have PFAS intentionally added to them, and then you will be even more disturbed to find out how many things contain PFAS incidentally, mostly due to contaminated water supplies.

Even with all of this effort, and more I'm not detailing in this comment, I am exposed to PFAS in the food supply and water supply daily, and in a myriad of other ways. It's impossible to avoid, even with a major budget and being extremely conscious of this issue. There is no way to get away from it. The entire world is contaminated. I don't even know how much my mitigations have any helpful effect towards my health, because it's so difficult to mitigate.

Well, not forever. Global population will peak end of century (sometime between 2055-2084) and then begin to rapidly decline based on fertility rate curves. Solar PV panels can be recycled 100% today, trivially, as can lithium and sodium batteries (these materials are abundant in the Earth's crust, but only so much will be needed to establish a circular supply lifecycle loop). I suppose we can argue about the scale of mining operations. Certainly, low carbon powered mass transit whenever possible vs light vehicles and aircraft. This is Africa and India's opportunity to "do better" based on what China has accomplished (having had the chance to ride their high speed rail and ride in their autonomous vehicles) with regards to urban planning, civil engineering, and infrastructure investment, being the last parts of the world that will develop.

I'm a huge rails fanboi but the state of Stimulus and Hotwire make me sad. The concepts are awesome, and I think the execution might even be good. But the documentation is so incredibly horrible that I have a hard time even getting started, and I can't learn enough about it to answer the question of whether or not using it in any given project will end with me painted into a corner.

> As time passes there is more fiat in circulation, which means fiat is worth less

This isn’t always true. For one thing, the amount of fiat in ‘circulation’ isn’t just a matter of “count up all the bills printed”, but is affected by how much leverage exists in the world and many other things.

Second, even how much a fiat dollar is worth is also a factor of how much productivity there is in the world. To understand what I mean, let’s imagine a super simple economy with only fiat dollars and wheat. Every dollar is only used to buy wheat.

Say there is $1000 in bills and 1000 pounds of wheat. Each dollar is worth 1 pound of wheat. Then, we print an extra $1000 in bills; that would be inflation, and now you can only buy 1/2 pound of wheat for a dollar. That is what people imagine when we talk about printing more money causes inflation.

But what if new technology gains means we are able to produce 4000 pounds of wheat for the same amount of work; now, each $1 can buy 2 pounds of wheat. Even though we printed more money, the economy grew even faster than we printed extra money, so we didn’t get inflation and instead prices went down.

Inflation is always (generally) about the ratio between currency production and economic output growth. You can’t just look at one side of the equation.

> Mojo is a major threat to the long term development of the Julia community

Mojo has 3 disadvantages compared to Julia:

1) The core team is focused on the Linux+servers+AI combination, because that's where the money is.

2) Less composability due to the lack of multiple dispatch.

3) The license.

Like I said, for my personal use, it's Linux.

For work, I don't choose, it's chosen for me. My company oriented to "zero-trust" remote work even before the pandemic. That means that transition away from being a Microsoft shop was easier (they were Windows / .Net before 2017, but cloud-everything changed that).

For personal use I will 100% advocate Linux over Windows. You're advocating Windows because it's easier for you to ship boxes to employees. Not because it's better for the employees.

> So...should warrants be required for this kind of Flock data also?

Based on another incident [0] I feel Flock's explanation for their actions boils down to:

1. "We are familiar with the customer the person claimed to be an agent for."

2. "We didn't know whether the person was doing something illegal with the data... And we don't want to know, and we don't try to find out."

3. "They didn't force us. They gave us money! We like money!"

As you might guess, I don't find these points especially compelling or exculpating. Certainly nothing that would/should stand up against state or local laws that prohibit the data being shared this way.

Lawful intercept laws exist, and they've been sort-of functional for ages.

Apps like Signal don't entirely fall within the scope of these, which is the cause of the current manic attempts to grab more powers.

My point is that these powers grabs should be resisted, and that new services should be brought into the fold of existing laws.

The prevailing opinion here seems to be that, instead, state hacking should be endorsed. Which, well...

I have no interest in reading anti-AI arguments in 2025. After all, where were they when AI algorithms were being developed back in the 50s and 60s?

They were in the library. Philip K Dick among others wrote extensively on likely downsides of such technology during the period you mention. Even were this not the case, you're basically arguing that nobody under the age of 60 has any right to complain because they weren't around when the concepts were first articulated. This is asinine.

I grew up in a small town in rural Alaska that would have been completely under glacier ice when Columbus landed in North America. In the time between Captain Cook exploring the area in the 18th century and the next western survey a hundred years later, the coastline had been transformed by glaciers receding and revealing inlets hadn't been there for Cook to map. The glacier that was directly in between my town and the highway to Anchorage when I was a child is all but gone now, and there is a road.

Sure, but those specific kernels would require some sort of verification method to make sure they are actually the kernel it says it is (and not a modified version pretending to not be modified) which would require code signing by a trusted third pasty, use of Trusted Platform Modules, and restrictions on what modifications a user can make to their kernel.

All of these things are pretty much non-starters for Linux users. You might as well just use windows if you are going to go that route.
