brohee··on Amateur armed with ChatGPT solves an Erdős problem
In the end "proofs" that are not machine checked will be left unread unless submitted by someone very respected in the field...
brohee··on The operating cost of adult and gambling startups
The miners are the middlemen, and they can chose to take your transaction or not. Should bitcoin ever be actually used for payment, it's not to too far fetched to think miners could be forbidden to validate transactions involving a blacklist of addresses...

Likely, https://www.reddit.com/r/forexposure/ material otherwise
brohee··on The Bromine Chokepoint
Actually, Ingas the company very much survived and moved to the Odesa region (https://ingas.ua/en/pro-nas/).

And they still have Neon in their catalog so most likely another case of impressive Ukrainian resilience.

brohee··on The Bromine Chokepoint
Odesa is not and has been hit less than more Eastern cities. OTOH I'd assume Ingas in Mariupol ceased to exist for practical purposes.
brohee··on ML promises to be profoundly weird
The general point is not. Iceland and Easter Island were fully deforested way before the industrial age. Countless species went extinct in Britain and more examples abound.
brohee··on A cryptography engineer's perspective on quantum computing timelines
"This is one of the few domains where having access to a quantum computer ahead of others could translate directly into financial gain"

Doubt, the moment people get vocal about their fund being stolen that will be it for crypto, it will crash the bank run. The only way it could work is that if you steal too little to be noticed, which will also be too little to finance your venture...

brohee··on A cryptography engineer's perspective on quantum computing timelines
I'm working on just that in some IoT context, and a lots of chips I have to deal with only have hardware support for AES-128, so it's a little more complicated...
brohee··on A cryptography engineer's perspective on quantum computing timelines
Yeah and some of the figures often quoted like consuming 14% of the electricity produced in the US are wrong, it was below 1%. https://ui.adsabs.harvard.edu/abs/2011APS..APRH13004R/abstra...
brohee··on A cryptography engineer's perspective on quantum computing timelines
Yeah that's treating D-Wave "breaking" RSA-2048 as the fraud that it is. They didn't factor anything, they computed a square root.

I'm still dubious about the accelerated timeline given what quite a bit of what is presented as progress in the field is fraud or borderline fraud when inspected closely. (e.g. some of the recent majorana claims by Microsoft are at best overhyped, at worst fraud)

brohee··on F-15E jet shot down over Iran
$1B per year for Hezbollah is like $1 a month per Iranian.I doubt it changes the Iranians living conditions much...
brohee··on Ireland shuts last coal plant, becomes 15th coal-free country in Europe (2025)
Sorry, the manufacturing learning curve. The most widgets you make, the cheapest they get. The effect was absolutely stunning for batteries and solar panels (https://ourworldindata.org/grapher/price-of-lithium-ion-batt...).

We make too few nuclear power plants for them to have a noticeable learning curve, and recently each subsequent one ends up more expensive than the latest, notably because of safety regulation. Korea and I think China had the best success in that regard (and France in the 80s) by being able to make real series, but you don't really see those now except maybe China.

More here: https://ourworldindata.org/learning-curve

brohee··on RISC-V Is Sloooow
It's one more instruction only if you don't fuse those instructions in the decoder stage, but as the pattern is the one expected to be generated by compilers, implementations that care about performance are expected to fuse them.
brohee··on Ireland shuts last coal plant, becomes 15th coal-free country in Europe (2025)
Not cost competitive with solar+batteries in many locales (less so the closer to the poles), and no learning curve, if anything a negative learning curve, nuclear never was more expensive than new nuclear.

And off course societal (and geopolitical) acceptance issues.

brohee··on An Interesting Find: STM32 RDP1 Decryptor
It makes devices using those (extremely popular) chips easy to clone as you can dump the firmware (firmware that sometimes also contain secrets, like cryptographic keys or API keys).

Not world shattering, but damn annoying (I myself handle a few millions of those in a connected object deployment and at the very least it warrants a revision of the risk analysis, as the attacker level got lowered some scenarios became more likely).

brohee··on I’m joining OpenAI
I guess OP meant https://blog.cloudflare.com/moltworker-self-hosted-ai-agent/ but that's a bit preposterous...
brohee··on I’m joining OpenAI
Exactly, quality of code is one of those necessary but not sufficient things... If you are somehow successful without quality of code (e.g. early Twitter maxing Rails performance) you end up either crash and burning of spending crazy amounts on infrastructure/rewrites (and often both).
brohee··on Over 36,500 killed in Iran's deadliest massacre, documents reveal
Datapoints :

https://en.wikipedia.org/wiki/Jallianwala_Bagh_massacre 400-1500 civilian deaths by 50 British soldiers armed with bolt action rifles (tried to get machine guns on site but thankfully couldn't)

https://en.wikipedia.org/wiki/Heinrich_Severloh Possibly single handedly killed an hard to estimate count of US soldier, but possibly in the hundreds (he had people supplying him ammunitions).

Crowds are just easy to thin with repeating firearms and a good supply of ammo...

brohee··on Amazon is ending all inventory commingling as of March 31, 2026
It's pretty optimistic. They certainly cannot "uncommingle" existing stock, so you may be able to buy new product with better source assurance, but for existing products...
brohee··on Sinclair C5
It's a collectible but the remaining ones can likely be improved very much with modern eBike parts, lighter and more powerful motor and batteries...
brohee··on Eurostar AI vulnerability: When a chatbot goes off the rails
They should really name and shame the person that called it blackmail. S̵l̵a̵n̵d̵e̵r̵ baseless accusations should have professional consequences...

Replacing all competent but ideologically unreliable people by reliable but incompetent people got more to it. See "Politicization" in https://en.wikipedia.org/wiki/PDVSA?wprov=sfla1
brohee··on The Ridiculous Engineering of the Most Important Machine [video]
Basically an ASML infomercial, but probably the best intro to the EUV process.
brohee··on Bluetooth Headphone Jacking: A Key to Your Phone [video]
A friend worked in an audiophile shop during his physics master and he'd swear the customer base was the most gullible bunch he ever saw... And mostly unswayable by rational arguments.

In any case someone ought to shear the sheep....

You'd think Sony would have learned from the PSN debacle, but alas...

Now I need to setup to check if my headphones are still vulnerable...

Firefox reader mode as always saves the day.
brohee··on Firefox is becoming an AI browser and the internet is not at all happy about it
This is not a position based on anything factual. If you have evidence of a setting not being honoured it will be treated as a bug and fixed, there is no evidence of bad faith about that that I can recall.

As for about:config, if you submit working patches to better expose options you care about I'm pretty sure they'll be considered, but every complex software has obscure options not exposed through a polished UI and frankly it's OK...

brohee··on I wasted years of my life in crypto
> Can you tell me another way of buying something over the internet without tying the purchase to a government ID?

By using a prepaid (debit|gift) card bought for cash in a convenience store? Much better anonymity that way. And much less volatility.

brohee··on I wasted years of my life in crypto
You forgot the money launderers, in both ecosystems. Casinos are the original tumbler.
