Open weights AI just does not have the same economics as open source software. You can’t rely on volunteer effort to provide compute or do training runs and you will not be able to profit from inference on your model, sell related services or gain unique advantages from people building on your tool.

A lot of discussion on open weights models seems to assume there is a clear incentive for building them. I don’t see how is the case. Unless you have no need for money (government sponsored?), there are no real ways to capture value from your investments in a model even as training cost increases.

Un Founder de estos de las eatartás ya estará pensando en un servicio de creación de perfiles en redes sociales falsos para entrar en EEUU, con IA, por supuesto. Mentalidad de optalidón y eso

Love to see increasing gender equality among the cyber criminal ecosystem.

“O alguien de su entorno”

The EPA has removed references about humans causing climate change from its website.

No US government website can be trusted for science information.

“Regression to the mean” is something they don’t like

Not sure if @cpaxton.bsky.social came up with this or paraphrased it from someone else, but I’d be fine saying that “A robot demo video tells you that the robot can do no more than exactly what it did in the video” is Paxton’s Razor

Google's Titans, a new architecture that combines the speed of RNNs with the performance of Transformers. It uses deep neural memory to learn in real-time, effectively scaling to contexts larger than 2 million tokens.

When I traveled in China I had to get a letter from my editor confirming that I wasn’t on assignment and wouldn’t be reporting while in the country. I was also advised not to travel with pens or notebooks.

This new US rule IS MUCH WORSE

if you can test it you can vibe code it

therefore

if your tests are manual or fake or meaningless or slow or break a lot

you're fucked until you fix that

nothing new under the sun

For a moment I've read "Git repos" 😅

Hacklore is a blend of hacking and folklore—modern urban legends about digital safety. Hacklore spreads quickly and confidently, passed from person to person as if it were hard-earned wisdom. But like most folklore, it isn’t grounded in reality, no matter how plausible it sounds.

San Juan de Gaztelugatxe never stops surprising me. Different trips, different light, different weather — One of the most magical locations in Northern Spain and a highlight of my photo tours.

Finally, someone wrote it down in a book:

To understand what is going well/poorly inside your engineering org: ask the devs what this is! Talk to a bunch of them to get a good picture

From the excellent new book by Nicole Forsgren and Abi Noda called "Frictionless"

Arrived yesterday

Ok, gracias

¿Se da también el dilema de invertir hoy o esperar a que bajen aún más los costes (hasta que la bajada absoluta y no porcentual por "Moore" ya no compense)? ¿O el resto de costes ex-silicio ya es suficiente para compensar?

Vengo a introducir otro elemento más de subjetividad, el tono de 256 Hz aunque se pueda expresar como potencia de 2 en realidad oculta el hecho de que el Hz como unidad de medida es el inverso del segundo .... y el segundo es ¡¡¡totalmente arbitrario!!!

"oscila" 😜

Experts vs. WiFi privacy vs. VPNs Recently on the socials there was a discussion whether VPNs are needed to protect your privacy while on WiFi.

Some in cybersec were debating how much VPNs protect your privacy while on public WiFi hotspots. I wrote some technical notes.

LLM APIs are a Synchronization Problem Maybe the LLM message APIs should be rethought as a synchronization problem.

I am also gradually coming round to the view that interaction between humans/client apps and (perhaps multiple) AI agents is a state synchronisation problem that probably needs CRDTs lucumr.pocoo.org/2025/11/22/l...

Turrón?

I really wish we'd stop calling them climate "skeptics" or "vaccine skeptics", if you jump off a cliff we don't call you a "gravity skeptic"
