brohee··on Who are the fire-tamers?
Since data is now the plural of anecdote... Frenchman here. Someone I knew fell from his bike without appropriate gear and ended up in the burn ward. His wife was very into the fire tamer thing and sent him a few practitioners...

He took the morphine.

On another note, I had respect for Aeon as a publication, and now I got a lot less.

brohee··on 45°C cooling design cuts data center water use to near zero
In the most nuclear country, France, power plants can't rise the river temperature by too much legally and yes it is an issue in summer with less water flowing.
brohee··on The founder's playbook: Building an AI-native startup
I know in which DC you are hosted and will cut your electricity off.
brohee··on Tracing a powerful GNSS interference source over Europe
Celestial Navigation is also doable even in daylight nowadays, e.g. https://sodern.com/en/ranges/astradia
brohee··on Higher usage limits for Claude and a compute deal with SpaceX
Because you'd need to trash the old GPUs in order to make room for new GPUs. Right now new GPUs get online mostly in new DCs. TSMC fab capacity is much more limiting than DC building and it will likely keep being the case. It's much easier to build a DC than a fab.
brohee··on Spirit Airlines Is Winding Down All Operations
Europe has passenger trains that work. What would be a short flight in the US, e.g. London to Paris is done more my train through the chunnel than flying unless you got a connecting flight.
brohee··on Spirit Airlines canceled all flights and is going out of business
It's quite possible other carriers would have gone around the worst and that the economy airline saved fuel.
brohee··on I built my own hair electrolysis machine
Step 2, put the needle on a gantry (I suspect you'd need more like 5D CNC to enter the pore with the right angle) and seek and destroy hairs... As it is it saves money but not time nor skill...
brohee··on GoDaddy gave a domain to a stranger without any documentation
That's one of the reasons I can walk in the main office of my registrar within an hour. It's clearly not available to everyone but it's especially important that if you can't do that you can at least conveniently sue your registrar... So at the very least in your jurisdiction.

So much is tied to DNS and particularly email...

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...
brohee··on ChatGPT Images 2.0
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...
