Changes proposed for ADB could kill an entire ecosystem of open-source power-user apps, mobile developer setups, and rootless privacy tools based on Shizuku.
What HN said:
microtonal: I am generally in favor of security improvements, but I do not really see much of a benefit here. This attack vector requires both that the user enabled developer settings and that they have remote adb enabled. So, this does not seem to be a realistic attack vector for 99.
ourcat: Amazon crippled the ADB functionality on FireTV Sticks a while ago. Making it an absolute pain to build and debug TV apps on. Currently, the only way to test is to install a release build every time.
0x_rs: Limiting ADB is the obvious next step. Even if this one specific feature request does not come to pass, Google has cornered everyone into relying on a developer interface for any normal personal computing tasks, whether running on-device or through USB/wireless.
eviks: > Spamming the thread will only cause Google developers to lock the issue, ignore valuable community feedback, or stop sharing public updates about this change entirely. So nothing would change (they can also lock away your "valuable community feedback" because what bothers them...

Every website I visit, I steal a button from it. Check out my stash!
What HN said:
donohoe: I have noticed on occasion websites with a missing button. Now I know what happened. Finally, closure.
gkoberger: There's a Chrome Extension he made based on this: https://anatolyzenkov.com/stolen-buttons/button-stealer I used it for a bit until I realized... I probably didn't want a third party reading all my traffic. But I did like having it for a bit.
input_sh: Too bad they're just static, as the website doesn't copy the hover state or the on-click animations.
binaryturtle: I may have missed one by looking at this huge dump, but NONE of the "buttons" I saw there actually looked/felt like a button. Something I can feel that I press it down and it gives proper visual feedback, like a little 3D effect. I'm old-school. :)

What HN said:
busfahrer: For anyone who enjoys this sort of thing, I found this postmortem of an Alone in the Dark clone for PICO-8 highly informative: https://www.lexaloffle.com/bbs/?tid=3804
alex-moon: What an excellent example of designing for the medium instead of trying to make the medium do something it's not good at! Your whole approach shows a real love, like a delicate respectfulness, that I think characterises early games and is less apparent as the systems get better (...
wewewedxfgdf: Highly relevant: Surface-Stable Fractal Dithering https://runevision.com/tech/dither3d/ https://www.youtube.com/watch?v=HPqGaIMVuLs
tslmy: This is breathtaking. I did something similar[1] porting a 3D dice roller I wrote to a $60 GBA clone, and I thought that was hardcore already. This is next level. [1]: https://blog.myli.page/rolling-dice-on-a-60-handheld-08be278...

Open-weight models are becoming the foundation for the next AI ecosystem. The US should compete in it, not wall itself off.
What HN said:
drnick1: > American labs need to release frontier-grade open-weight models under licenses that startups can actually build on. To be fair, OpenAI has released a couple of (then very good) OSS models.
ozgung: Everyone is talking about banning Chinese models but nobody talks how it is feasible to ban them. I think it’s impossible simply because technically there is no such thing as a “Chinese model”.
firasd: One of the strangest things in the AI industry is 'tokenomics'. It's not very clear why using GPT-4 in early 2023 was so expensive and then six months later 20 bucks could get you a fair amount of GPT-4 inference.
pianopatrick: Eventually I think to truly be like Kubernetes, you would need an AI model that has public training data and that a lot of companies collaborate on. Might make sense eventually. Same logic as companies working on Linux. "An AI model is a business necessity.

For some of the world's rarest monkeys, the path to survival now runs through a simple network of ropes.
What HN said:
culi: Just wanna say, Monga Bay is an incredible publication that doesn't get enough attention. As someone who follows a lot of environmental news, they routinely cover important topics and do original journalism on stories I hear nowhere else.
ynac: We just had our first bear crossing on a wildlife here in the Northwest. https://www.seattletimes.com/seattle-news/first-black-bear-u... I know these things are more complicated than they seem at first, but whenever these stories surface, I immediately go to an idealistic childho...
aorth: This is really cool. We have them in Kenya too. https://www.colobusconservation.org/how-to-build-a-colobridg...
korijn: For one moment there I thought Amazon had done a good thing!

Hello there! This is my personal website and it is allergic to SEO.
What HN said:
matsemann: Almost two decades ago I used a software called Rasterbator to dither an image into dots, blowing it up to multiple A4 pages one could then decorate a whole wall with. Up close it would just be circles of various sizes, but from a distance the image would show up. Super cool.
trentor: I was a rotogravure printer in another life, and this post made me a bit nostalgic. In intaglio printing you usually don't see these patterns because the electrostatic assist pulls the ink out of the cells, and the colors blend together more. It's more akin to a developed photo.
rahimnathwani: If you're doing halftoning with the intent to get custom DTF (direct to film) prints for t shirts, you might find this tool helpful: https://tools.encona.com/dtf It aims to 'knock out' some areas of the image: make them transparent in the digital image so those areas are not part...
zeraye: A few years ago I made this fun little app https://dithering-sigma.vercel.app/. May be interesting for someone. Source code https://github.com/zeraye/dithering.

A complete guide to building an apartment-sized aquaponics system
What HN said:
NoLinkToMe: I love the idea of hydro/aquaponics and built a system as a student more than a decade ago. It’s a fun project. But as a form of agriculture it’s a spectacularly bad idea at home. This setup is about 1 square meter of NYC space, that’s about $18k.
Epa095: Cool project. I wonder how large a tank you need to get room fle aquatic animals you would actually eat. And as a small aside, idk how one can write sentences like this and not immediately revolt and switch to metric: Since a gallon of fresh water weighs roughly 8.
bob1029: I recommend starting with deep water culture if you want to get into this sort of thing. Aquaponics is like hardcore mode. Shopping for fish so that you can grow plants is a really neat idea, but not where I would start if I didn't want to get frustrated in a hobby setting.
WillAdams: I can still remember ads for the "Biotron" flourescent grow system in various magazines back in the '70s --- the ad featured roses, but of course the actual usage was typically for growing marijuana.

What HN said:
inigyou: Walked around Fusion Festival with Bitchat running. Saw about 20 other devices and a few messages. Nobody replied to my messages. So usage isn't zero, but 20 devices out of 80000 people isn't a lot.
plebian: If they care so much about availability maybe they should reconsider including libs.gms.location and be available on F-Droid (https://gitlab.com/fdroid/fdroiddata/-/merge_requests/24907#...)
Cider9986: People interested in BitChat should download it just so you have it in case it gets popular or you find someone to use it with. I tested it and it's surreal to text without WiFi or cellular.
dmix: That Radicle site design is an interesting take for a git repo platform. Good use of full width spacing, well thought out navigation, nice code rendering. I dig it.

A trackpad worn on the roof of the mouth: hands-free control of your devices, driven by the tongue. From Augmental.
What HN said:
arm32: As someone who uses head, eye and facial gesture tracking regularly while doing long medical treatments which tie up both my hands, I would really love something like this.
astrashe2: This seems really clever. I don't know anything about what it takes to serve the targeted needs, so I could be wrong. But it's the sort of thing that pops out as really cool and useful, tech that makes the world better.
Tomte: Surgery robots have a tongue controller. It takes a while to train on that, but when you‘re trained your tongue muscle is the most precise way to control, say, subtle incisions deep inside the brain.
t-3: If it can be made comfortable and cheap enough, this could be useful as an interface for AR glasses. The tongue is very sensitive and dextrous, and I imagine that even swipe typing with this kind of touchpad is probably feasible.

What HN said:
cube00: This kind of end to end documentation is invaluable when you're trying to troubleshoot. I had a service complaining about the root file permissions which changed between Fedora versions [1].
28304283409234: Meanwhile the bluewashing seems to be keeping a steady pace. https://techrights.org/n/2026/07/22/IBM_is_Not_Done_Destroyi...
mdlxxv: Truly a "Beefy Miracle". https://web.archive.org/web/20230112002240/https://beefymira...
hangrybear666: So as a relatively fresh Fedora user (2024) who just sold their Windows PC (2025) and is in love with the OS, where would be a good place to look for areas to contribute in? Is there a place where Fedora maintainers write down what parts of the pipeline are in need of volunteers?
