drpixie··on There are no "rogue" AI agents
The really interesting thing about "AI" is it has shown how easily we are fooled, and how willing we are to be fooled.

There's some great research areas opened up by "AI". But it's research into people, not "AI". We should be looking into how human vision works, given that we take obviously generated images to be real. And how we grant intention to text which clearly has no intention.

drpixie··on When did Google get so weird?
On Bing!!!! Sorry, in the back of my mind, bing is that very sad MS search that was terrible at everything :) And it gave you something useful - astonishing.
drpixie··on Revealing the details of how OpenAI agents hacked Hugging Face
Or, it's impressive that, amongst the millions of hacks it has copied from various chat sites, were some that worked in this case.

The scale of these things is impressive, but the mechanism is not much better than brute force.

drpixie··on Saving Jet Fuel
Hi author, where did the aircraft and engine data come from?

That data looks to be rather arbitrary. Real aircraft performance is hugely dependent on aircraft weight, altitude, and ambient (air) temperature. And engine performance is very dependent on air temperature and airspeed. So your table of cruise/climb speeds etc might produce interesting results but the results are not going to be at all realistic.

To give you an idea of data complexity, all airliners come with hundreds or thousands of pages of closely printed tables giving performance at specified weight, temperature, altitude, etc.

drpixie··on Stop externalizing the cost of your AI use to me
> if the value is in the prompt, give me that prompt – I have access to a model too.

Absolutely. I don't want to waste my time reading pages of (literally) mindless slop.

If you can't be bothered writing well, just write points. Don't use "AI" to expand your points into slop. I might read your points, and will judge you on your lack of time and/or care. But I will despise your slop.

drpixie··on On the Navier–Stokes Millennium Prize Problem
That is how the PR reads, but is not at all what happened.

A team of highly trained and skilled people used an AI tool, through many many instructions (prompts), to produce a specific mathematical theorem. The tool is impressive, the result (possibly/probably) interesting, but the PR skips the vital role of the humans (for the usual PR reasons).

drpixie··on Ask HN: Resources to get good at soldering?
And be your own critic. Aim for great, not just ok. Find out what dry-joints look like. And too much solder. Then aim for a really nice job :)
drpixie··on Models Don't Go Rogue
Yeah - and if they wanted some cheap PR, that's one way to get it.
drpixie··on I'm not anti-AI, but I have QUALLMS
Their basic point is very valid, and the term "AI" is now so overused that it's become essentially meaningless.

Recently I've heard "AI" used to mean:

* using large language models for code/text/image generation

* goal-driven search of a problem space

* pattern extraction from images

* algorithmic decision making

* audio pattern recognition

* something (unspecified) using lots of computers

* and more trivially, "doing it on a computer"!

drpixie··on Let the machines in
LLMs have shown us how easily humans are fooled. Just provide a similar answer to which was seen in similar circumstances, and we start misleading ourselves into it's method and "understanding".

Though perhaps I'm wrong that people use a model of the world to think through answers to queries. Maybe many people do just repeat something like whatever they heard before. In which case, LLMs make as much sense as the average ignorant human.

drpixie··on GPT-5.6 Sol Ultra produces proof of the Cycle Double Cover Conjecture [pdf]
It's been amusing to watch the points bounce up and down on my comment.

I guess equally half the readers agree with my sentiment, and half down-vote, being upset by my attitude to the AI industry :)

PS. I'm quietly waiting for the bubble to pop - the main interest being will it pop with a bang and cause grief to many, or will it just go with a long drawn-out fart that can be ignored by most.

drpixie··on GPT-5.6 Sol Ultra produces proof of the Cycle Double Cover Conjecture [pdf]
> GPT-5.6 Sol Ultra produces proof of the Cycle Double Cover Conjecture

Very misleading article title.

Title should be "Un-named humans produce unverified proof of CDC Conjecture using GPT-5.6" ... but I expect only advertising copy when it comes from the AI industry.

drpixie··on One KW wind turbine without civil engineering
Is there anything on the website that isn't "AI" generated? Oh dear, oh dear, oh dear :(
drpixie··on One KW wind turbine without civil engineering
Can't imagine it would survive the first descent storm. Unlike conventiolnal turbines, it doesn't seem to have any way of protecting itself.
drpixie··on All of human cooking compressed into 2 megabytes
Few thousand? Really? Larousse Gastronomique is 3600 pages, averaging maybe 1 recipe and 1 ingredient per page - and that's just classic French cooking.
drpixie··on A fundamental principle of aeronautical engineering has been overturned
Me too. The number of "revolutionary" designs that are announced but disappear makes me cynical. Looking wings on real aircraft, unless freshly painted, they're pretty close to finely sanded :) If the airlines and engineers saw a significant performance degradation with wear, they'd be out there polishing and repainting wings.

On a similar note - How many times have you seen announcements about someones blended wing that is going to save 50% fuel? But there are very few blended wings in nature (eg. rays), and those are in a very slow-speed regime.

drpixie··on Google broke reCAPTCHA for de-googled Android users
I'm inclined towards keeping an ancient android for those apps that require it, and maybe something open for actual use. Or perhaps a crappy old android for android and a small non-android tablet/laptop for daily-driver stuff, which always works better as a computer anyway!

I'm also becoming open to using software that lies to google about what it is :) Google will treat us like sh*t, why shouldn't we reciprocate.

drpixie··on Google broke reCAPTCHA for de-googled Android users
Same reason as "make another (better) windows" is very difficult - almost everyone wants to be able to run existing apps and drivers, so you're forever playing compatibility catchup with android (or windows).

That's the reason companies are desperate to be first/biggest - once you're it, you're it until you finally fall on your face and dwindle to a nobody.

drpixie··on What can we gain by losing infinity?
I've always felt that to treat infinity as number is to commit a category error (aka type conflict), to confuse the process with the outcome of the process. Infinity has proven to be very useful, but usefulness doesn't make it always valid.
drpixie··on Replacing an Apple Time Capsule? Skip the Ubiquiti UNAS-2
It's a great pity but I won't be buy more Ubiquiti hardware unless their direction improves. I loved the Ubiquiti hardware until a year or so ago. It was well spec'd, well priced, reliable, and it was easy to upgrade to OpenWrt. (Changing to OpenWrt was definitely an upgrade - get away from their you-must-do-it-our-way software. OpenWrt isn't perfect but mostly just works.)

But Ubiquiti have changed. The new hardware is silly - little screens and do-everything-on-an-app-with-our-cloud firmware. It's my infrastructure, I don't want to rely on your cloud! I only hope they go back to making good hardware and letting us use it for what we want.

drpixie··on Alberta startup sells no-tech tractors for half price
>> However, the tech exists for a reason and is not inherently bad, the issue is the lock-in, the lack of choice and interoperability.

The marketing excuse for the tech might be features or efficiency, but the reason for the tech is lock-in and minimising product lifetime.

The days when manufacturers had friendly, cooperative relationships with their customers are long gone :( Can we bring them back? I hope so, but am not hopeful.

drpixie··on IPv6 traffic crosses the 50% mark
>> It has barely hit 50% and it's already plateauing.

Well, the curve has got to level-out at 100%.

drpixie··on 10% of Firefox crashes are caused by bitflips
From Corsair

>> DDR5 technology comes with an exclusive data-checking feature that serves to improve memory cell reliability and increase memory yield for memory manufacturers. This inclusion doesn't make it full ECC memory though.

"Proper" ECC has a wider memory buss, so the CPU emits checksum bits that are saved alongside every word of memory, and checked again by the CPU when memory is read. Eg. a 64 bit machine would actually have 72 bit memory.

DDR5 "ECC" uses error correction only within the memory stick. It's there to reduce the error rate, so otherwise unacceptable memory is usable - individual cells have become so small that they are not longer acceptably reliable by themselves!

drpixie··on How many chess games are possible?
As I understand it, the 50-move rule must be invoked by one of the players, lets assume our immortal players agree not to invoke that rule.

The 75-move rule is automatic, so that would be the limiting factor.

Note, that 75-move rule is only applicable after no pawn has moved or a piece has been captured. So our immortals can do a lot of shuffling things around.

I'm thinking that the number of moves of the longest game is going to be (16 pawns * 7 moves each + 16 pawns being captured + 14 other pieces each being captured, not the kings) * 75 moves for shuffling around = 10650 moves.

That's only 1 week at 1 move per minute! But given the permutations, it might take much longer to calculate the actual moves required to get to the end state :)

drpixie··on Luxury Yacht is a desktop app for managing Kubernetes clusters
Personally, I would like the name to be somehow related to the system. When I'm facing a stack of names and icons, make it easy for me.

Names without some connection to the thing are just more difficult. Maybe the name isn't descriptive - you can only have some many versions of ed, edit, edt, vedit, gedit, zed... I'm perfectly happy with puns and jokes - eric can be connected to (monty) python. It's the connection that makes it memorable. Even yacc and grep have some connection to the program.

I've been using Vivaldi browser for a while now, but neither the name nor icon have formed a natural connection to browsing for me. Same with Lazarus (an IDE), no obvious link (worse, it's nothing to do with raised from the dead). But "Bluefish Editor" at least tells me what it does, not a full description, but plenty.

drpixie··on Luxury Yacht is a desktop app for managing Kubernetes clusters
And I though the arbitrary, non-mnemonic, unrelated-to-anything project/app names had got too much ... obviously we're way past that :(
drpixie··on Ideas are cheap, execution is cheaper
To me, it looks like the whole article was generated by AI. Using slop to promote slop ;(
drpixie··on When hardware goes end-of-life, companies need to open-source the software
How about requiring all APIs to be open? Companies are free to run/maintain/drop servers and apps, but we'd have the ability to use the hardware we bought, if we write our own apps.

That might actually be good for security. If APIs must be public, proper cloud security becomes necessary (rather than relying on obscurity).

drpixie··on The Cray-1 Computer System (1977) [pdf]
There are several versions of the Cray 1 Hardware Reference manual online. They're not as descriptive as Design of a Computer, but still informative.
drpixie··on Show HN: PrintReadyBook
Oh great - yet another way to get AI slop. Slop text, a slop cover - just raw slop, straight from the slopperizor. And the internet gets another little bit deader.
