luma··on The USB Situation
Most USB C cables do have a label, but it's an electronic one. Desktop and mobile OSes could do a better job of surfacing this information for the user.
luma··on Why does it take so long to release black fan versions?
Noctua is awesome in a lot of ways, one of them is offering full CAD models: https://www.noctua.at/en/3d-cad-models
luma··on Tindie store under "scheduled maintenance" for days
etsy, mostly for lack of a better option and a lack of desire to self host, deal with taxes, etc.
luma··on A 3D Body from Eight Questions – No Photo, No GPU
My guess, the article itself is clearly AI authored and there are a fair number of us who don't particularly like the writing style. Further, it implies something about the original human's own valuation of this work - if they decided to let the machine handle it, why should I spend my own time reading what they didn't bother to write?
luma··on Cal.diy: open-source community edition of cal.com
I think it's more prosaic, OSS is great for building a userbase but not great at generating revenue. So just wave the OSS flag while you build a userbase, then pull out whichever flimsy excuse seems workable at the time when you want to start step two of your enshittification plan.

The only thing new here is the excuse.

luma··on Tindie store under "scheduled maintenance" for days
The site has been on life support for a decade, ownership has changed hands a few times, basic features promised 10 years ago never shipped, API is half implemented (eg. you can download an order but you cannot mark it shipped), and they still have no mechanism to collect state sales tax nor will they submit a 1090 as required by US tax law. I jumped ship 5 years ago when this became too much of a problem and not a single thing has changed in those 5 years.

Tindie was a great place for a hacker to sell a few widgets back in the day, but legal requirements have changed since then but Tindie has not changed a line of code in at least 10 years.

luma··on F-35 is built for the wrong war
The key difference is that "swarms of inexpensive drones" can be made in "swarms of normal looking residential garages". The entire enterprise can be decentralized making it much tougher to target with strategic weapons.
luma··on RedSun: System user access on Win 11/10 and Server with the April 2026 Update
Detected: Program:Win32/Wacapew.C!ml

luma··on RedSun: System user access on Win 11/10 and Server with the April 2026 Update
I can't seem to find any system files replaced, and the .exe was never executed. I'm running this in a test VM, but from what I can see, Defender signatures have been updated to block this prior to execution.

The exploit, from my reading, needs to be executed in order to do it's thing, but Defender isn't allowing it to be written to the filesystem on download.

Tried to download and Defender blocks it.
luma··on Trusted access for the next era of cyber defense
So who is at fault in your solution, the org who created and shipped the software bug, or the company that discovered it?

I don't see how OpenAI is Ford in your analogy as OpenAI didn't make the software that blew up.

luma··on Muse Spark: Scaling towards personal superintelligence
For one, they aren't using the latest version of many of the benchmarks. eg, ARC-AGI 2 and not 3, etc.
luma··on AI singer now occupies eleven spots on iTunes singles chart
Today there are zero mentions of Eddie in the top 100: https://music.apple.com/us/playlist/top-100-usa/pl.606afcbb7...

I'd really love to see an actual source on this claim.

luma··on Microsoft hasn't had a coherent GUI strategy since Petzold
Entirely AI. I just can't with this style anymore.
luma··on CEO of largest public hospital says he's ready to replace radiologists with AI
Brother-in-law graduated med school in the early 90s and has been a practicing ER physician since. We discussed this recently and he related that his advisors told him not to go into radiology back in the late 80s because the assumption was that computers were going to take over the field. He's not too far away from retirement and it's only now that we're starting to see some signs of this prediction from 30+ years ago.

As others in the thread note, there are plenty of concerns around operational use of AI solutions in the medical space, but radiology has a much larger target painted on it than other practices as a fair portion of the job (but certainly not all!) can boil down to high-skill pattern recognition from visual inputs. The current list of AI-enabled devices going through FDA approval is public, more than 3/4 of the list are targeting radiology use cases: https://www.fda.gov/medical-devices/software-medical-device-...

luma··on Coding agents could make free software matter again
You’re mixing up “using” with “copying”. You are allowed to “use” all of a book or movie or code by listening to or watching or reviewing the whole thing. Copyright protects copies. The legal claim here is than training an LLM is sufficiently transformative such that it cannot be construed as a copy.
luma··on New York City hospitals drop Palantir as controversial AI firm expands in UK
Amen.

People seem to struggle with the concept of private datacenters these days. Palantir customers tend to be the sorts of orgs that are pretty paranoid about their data, and they wouldn't be handing it over to some schmucks without being confident that those concerns were addressed. Militaries and governments generally aren't fuckin around with things like intelligence data, so I think it's reasonable that Palantir is able to make a convincing case to the world's most paranoid orgs that their data isn't being sent anywhere (and it'd likely be air gapped anyway).

Just because everything you touch is in the cloud doesn't mean other orgs aren't still building their own datacenters and then buying software to run inside.

luma··on HyperAgents: Self-referential self-improving agents
I'm not sure if you're familiar with the work from the lab of Mike Levin at Tufts but I'm betting you'll find it interesting if not. Here's a taste https://pmc.ncbi.nlm.nih.gov/articles/PMC6923654/

While I disagree with your notion that this is explicity due to gravity, the rest of your argument seems to align with some of this lab's work. Learning can be demonstrated on scales as low as a few molecules, way below what we would normally call "life".

luma··on Epoch confirms GPT5.4 Pro solved a frontier math open problem
And then an 18-to-20-something-year training run is required for each individual instance.
luma··on Epoch confirms GPT5.4 Pro solved a frontier math open problem
Modern LLMs, just like everyone reading this, will instead reach for a calculator to perform such tasks. I can't do that in my head either, but a python script can so that's what any tool-using LLM will (and should) do.
luma··on Baochip-1x: What it is, why I'm doing it now and how it came about
bunnie your book "Hacking the XBox" taught me how to get started on reversing electronics, took the fear out of the process, and replaced it with fun. Thanks for the multi-decades long effort you've made to make these tools available and accessible and approachable, your contributions to the hacker community are immeasurable and I cannot say thank you enough.

Thanks man!

luma··on No right to relicense this project
If automated AI rewrites are generally feasible, then the marginal price of nearly all software trends to zero.
luma··on AI and the Ship of Theseus
What you describe is essentially what happened, the AI result working from specs and tests was more performant than the original. The real AI you describe just rewrote chardet without looking at the source, only better.
luma··on Show HN: A native macOS client for Hacker News, built with SwiftUI
I'm trying to understand your position here. An app with it's own way to manage multiple browser windows is better, because you have too many tabs open in your browser. If you have multiple links open, the tab management is now a problem in your desktop app instead of the browser. If you don't, then you don't have to manage tabs anyway. What does this solve that a separate browser window doesn't, except not having any way to add extensions like ad blockers or tampermonkey scripts etc?
luma··on Show HN: A native macOS client for Hacker News, built with SwiftUI
I've never understood the concept of an app wrapper for a link aggregator (HN, reddit, etc). The whole goal is to provide links to external sources, and now I'm browsing the web in a limited web browser without all my extensions etc.

Am I missing some core concept here? Why would I want to browse the web in this app as opposed to a web browser?

luma··on What your Bluetooth devices reveal
You can do this for much cheaper - all four of your tires are broadcasting a unique ID to report tire pressure, the radio to pick it up is cheap (because cars), and TPMS has no facility to randomize or otherwise secure this.
luma··on Rome is studded with cannon balls (2022)
> The cannonball crashed into the church and went through a first wall. It then ended on the altar of the Chapel of the Virgin. [...] The cannon ball was walled into the left wall of the Chapel and a commemorative epigraph was added to it.

It wasn't showing the wall where it had crashed through, it's showing where the ball has been mounted into the wall for display.

luma··on New York’s budget bill would require “blocking technology” on all 3D printers
Really looking forward to NY funding upgrades to the computers connected to CNC machines which tend to be pre-2000 vintage running software that's even older.

The entire concept is absurd on about 10 different levels.

luma··on New York’s budget bill would require “blocking technology” on all 3D printers
If your goal is to buy the cheapest machine you can find in the world, chances are good everything you buy is going to come from China. That Prusa Mk3 you bought ages ago can be upgraded to the latest model, which means you have the option of turning that device into a lifetime machine, something ONLY Prusa offers.

Yes, the initial purchase price is higher, the lifetime price might not be.

luma··on Netflix Animation Studios Joins the Blender Development Fund as Corporate Patron
The Blender project is the model I hope FreeCAD can eventually follow. Like digital animation, the 3D digital design field has a pretty rough selection of tools and the UI on all of them leaves a lot to be desired. FreeCAD has been on an upward trajectory in the past couple years as more people lean into the project out of frustration over increasingly hostile pricing from the commercial solutions. KiCAD has seen incredible advances since CERN started pouring resources into it, I'm sure Netflix money is going to help Blender. Now to get some large engineering shop to consider FreeCAD as their exit path to Siemens/et al...
