I browser lanciati dai produttori di AI, che tipicamente sono versioni customizzate di Chrome/Chromium, sono molto poco sicuri. Non è una sorpresa, ma dovrebbe essere un monito.

Money quote: "Building on our previous disclosure of the Perplexity Comet vulnerability, we’ve continued our security research across the agentic browser landscape. What we’ve found confirms our initial concerns: indirect prompt injection is not an isolated issue, but a systemic challenge facing the entire category of AI-powered browsers. This post examines additional attack vectors we’ve identified and tested across different implementations.

On request, we are withholding one additional vulnerability found in another browser for now. We plan on providing more details next week."

Lo sapevate che nella Silicon Valley si usa sempre più spesso l'AI open source cinese? Costa meno e funziona meglio, per questo Airbnb e Thinking Machines Lab la usano nei loro prodotti. Il modello low cost cinese è molto efficiente e rischia di mettere in crisi il faraonico sistema americano.

Money quote: "Data from Hugging Face’s platform compiled by the ATOM Project, a US coalition in support of open-source AI, confirmed that. Chinese models have overtaken the US in terms of cumulative downloads by developers. The shift happened slowly, then all at once: In early 2024, Meta Platforms Inc.’s Llama had 10.6 million downloads to Alibaba Qwen’s meager half a million. By last month, Qwen had had 385.3 million cumulative downloads compared to Llama’s 346.2 million. And derivative systems built on Qwen now account for more than 40% of new language models posted on Hugging Face, while Meta’s share has fallen to 15%."

La globalizzazione prometteva un mondo senza confini, ma gli algoritmi digitali hanno frammentato le persone in bolle di pensiero simili, rafforzando l'omofilia e la polarizzazione. Anche se la diversità è a portata di mano, molti preferiscono la sicurezza emotiva delle comunità chiuse, il che aumenta la sfiducia nei confronti del diverso. Questa tendenza, guidata dalla preferenza degli algoritmi per contenuti emotivi e polarizzanti, minaccia la capacità di dialogo e consenso nella società. Tradotto: sono cazzi.

Money quote: "Internet anunció el fin de las fronteras, pero el algoritmo nos fragmenta en una infinidad de burbujas, islotes que nos confirman en nuestros sesgos; ¿han nacido nuevos límites que separan más que los geográficos?"

Era talmente ovvio che quasi non c'era bisogno di dirlo. I ricchi si sposano tra loro (e i poveri? Anche).

Money quote: "La clase social atraviesa todos los aspectos de la vida y el amoroso no iba a ser menos. En España las parejas no se forman al azar, sino que suelen estar determinadas por cuestiones socioeconómicas, lo que se traduce en que una persona se junta con quien más se parece a sí misma en términos de ingresos y riqueza. En la parte alta de la tabla, la tendencia se dispara. Quienes más ganan y más tienen se encuentran con una intensidad que triplica lo que ocurriría en una sociedad en la que los enlaces se produjeran de manera completamente aleatoria."

Il film Legend of Zelda, tirato fuori dal'omonimo videogioco, arriverà tra un po', ma forse ne vale davvero la pena

Money quote: "Nintendo’s Shigeru Miyamoto, who is producing the film, revealed the casting of Link and Zelda over the summer, writing in a social media post: “I am pleased to announce that for the live-action film of ‘The Legend of Zelda,’ Zelda will be played by Bo Bragason-san, and Link by Benjamin Evan Ainsworth-san. I am very much looking forward to seeing both of them on the big screen.”

English actor Bragason is known for her roles in the BBC One series “Three Girls” and “The Jetty,” as well as Disney+’s “Renegade Nell.” Last year, she starred in Euros Lyn’s vampire comedy film “The Radleys.” Ainsworth, who is also English, was the voice of Pinocchio in Robert Zemeckis’ live-action “Pinocchio” and played Miles in the Netflix series “The Haunting of Bly Manor.” He also stars in the Canadian comedy series “Son of a Critch” and appeared in an episode of Netflix’s “The Sandman.”"

E se molti super-centenari (quelli con più di 110 anni) in realtà fossero dei fake?

Money quote: "Tutto è cominciato a gennaio, quando la rivista scientifica Rejuvenation Research ha pubblicato un articolo del matematico russo Nikolay Zak secondo cui alla morte della madre, nel 1934, Yvonne Calment ne avrebbe preso l’identità per evitare di pagare una gran quantità di tasse di successione. L’argomentazione di Zak si basa sul confronto tra le fotografie disponibili di Yvonne e quelle di Jeanne Calment prima e dopo la morte della figlia, su varie incongruenze nelle interviste rilasciate da Calment da anziana, oltre che su un’analisi statistica secondo cui sarebbe poco plausibile che nel 1997 una persona abbia raggiunto i 122 anni di vita."

Letture per la domenica.

Secondo il sociologo francese Jean-François Bayart, gli ideali politici della generazione Z sono molto ambivalenti e facilmente recuperabili. In un'intervista a "Le Monde" il sociologo ha spiegato il fatto che, secondo lui, la recente ondata di mobilitazione dei giovani è una reazione alla rivoluzione conservatrice, a sua volta un misto di autoritarismo e predazione economica praticata da molti Stati. Questa reazione però non è esente da varie ambiguità ideologiche.

Money quote: "Depuis l’échec des « printemps arabes » de 2011, nous sommes entrés dans un âge de révolution conservatrice à l’échelle mondiale : Donald Trump aux Etats-Unis, Vladimir Poutine en Russie, Recep Tayyip Erdogan en Turquie, Narendra Modi en Inde… Il s’agit de phénomènes de restauration – ou d’instauration – de l’autoritarisme, à l’interface de l’exaltation de valeurs dites « traditionnelles » et de la célébration de la technologie. Les vieilles démocraties européennes n’en sont pas à l’abri. Les coups d’Etat au Sahel ou l’élection présidentielle au Sénégal en portent aussi la marque."

Il concetto è semplice: chi fa una vita attiva è sano, chi fa una vita sedentaria è malato. Il conto prima o poi arriva.

Money quote: "We’ve long accepted the idea that someone is “healthy” if their lab results are normal and they’re not taking medication. But what if that’s the wrong measuring stick? What if metabolic illness starts long before your first abnormal blood test?

Most metabolic diseases… type 2 diabetes, insulin resistance, fatty liver, etc, are present for more than a decade before a routine physical examination and blood tests will identify the issue. They are area under the curve issues… where the area is time. I discussed this concept at length in my book, Longevity Simplified."

Il mistero della scoperta della penicillina: nel racconto di Alexander Fleming ci sono parecchie cose che non tornano.

Money quote "For decades, scientists and historians have puzzled over inconsistencies in Fleming’s story. For starters, the window to Fleming’s lab was rarely (if ever) left open, precisely to prevent the kind of contamination that supposedly led to penicillin’s discovery. Second, the story is strikingly similar to Fleming’s earlier discovery of lysozyme, another antibacterial substance, which also featured lucky contamination from an open window. Third, Fleming claimed to have discovered the historic culture plate on September 3rd, but the first entry in his lab notebook isn’t dated until October 30th, nearly two months later.

Last, and most important: penicillin only works if it’s present before the staphylococci. Fleming did not know it at the time, but penicillin interferes with bacterial cell wall synthesis, which only happens when bacteria are actively growing. Visible colonies, however, are composed mostly of mature or dead cells. By the time a colony can be seen, it is often too late for penicillin to have any effect. In fact, the Penicillium mold typically won’t even grow on a plate already filled with staphylococcus colonies. For years, scientists have attempted to replicate Fleming’s original discovery. All have met with failure."

Alla faccia della privacy. Il colpo gobbo fa crollare le certezze perlomeno in ambito aziendale.

Money quote: "As reported by Android Authority, “Google is rolling out Android RCS Archival on Pixel (and other Android) phones, allowing employers to intercept and archive RCS chats on work-managed devices. In simpler terms, your employer will now be able to read your RCS chats in Google Messages despite end-to-end encryption.”

This applies to work-managed devices and doesn’t affect personal devices. And in certain regulated industries it just adds RCS archiving to existing SMS archiving. But employees in regular organizations view texting as different to emailing, especially given the expectations around end-to-end encryption. That’s no longer the case."

Internet come una foresta: la stiamo distruggendo. Un'immagine potente e affascinante nella sua drammaticità.

Money quote: "The story of German scientific forestry transmits a timeless truth: When we simplify complex systems, we destroy them, and the devastating consequences sometimes aren’t obvious until it’s too late.

That impulse to scour away the messiness that makes life resilient is what many conservation biologists call the “pathology of command and control.” Today, the same drive to centralize, control and extract has driven the internet to the same fate as the ravaged forests."

Ieri si parlava della fine di internet come la conosciamo. Ma, mantenendo le analogie vegetali, per fortuna ci sono i giardini digitali che vengono coltivati

Money quote: "The movement might be gaining steam now, but its roots date back to 1998, when Mark Bernstein introduced the idea of the “hypertext garden,” arguing for spaces on the internet that let a person wade into the unknown. “Gardens … lie between farmland and wilderness,” he wrote. “The garden is farmland that delights the senses, designed for delight rather than commodity.” (His digital garden includes a recent review of a Bay Area carbonara dish and reflections on his favorite essays.)

The new wave of digital gardens discuss books and movies, with introspective journal entries; others offer thoughts on philosophy and politics. Some are works of art in themselves, visual masterpieces that invite the viewer to explore; others are simpler and more utilitarian, using Google Docs or Wordpress templates to share intensely personal lists. Avid readers in particular have embraced the concept, sharing creative, beautiful digital bookshelves that illustrate their reading journey"
