It is so weird when younger people think that getting older means ceasing social participation

This is also why so many of you fear aging. You think that you will be forced away from life and society

Na Suécia o snus (cuja uma das marcas só é o Zyn) é tipo parte da cultura, o povo usa desde sempre, é uma praga, não entendo como é TÃO popular em todas as faixas etárias.

As vezes eu dou uma olhada no Threads (eu sei eu sei): me parece ser uma rede especificamente projetada pra me irritar. Absolutamente nada de aproveitável.

What privacy? Meta's smart glasses are filming unwitting naked people Meta's Ray-Ban smart glasses are a privacy nightmare, with footage of naked people, sensitive information, and violent acts captured and seen by Meta's AI and an army of employees.

Buried lede: Meta sends all your nudes to Kenya where humans annotate it and feed it to AI

Epstein, eugenics, and the far right Long after race science fell into public disgrace, Epstein was working to revive its core assumptions – and connecting biological hierarchy to far-right politics. As Dr Annabel Sowemimo uncovers...

On Epstein's "ecosystem of influence", among whose members there appears to be no "viewpoint diversity" at all:

"When ideas about inherited superiority are discussed in Harvard offices and at prestigious science festivals rather than fringe rallies, they acquire a dangerous sheen of credibility"

Frustrating how passive most Americans are about their country being the world's biggest threat. War to them is purely a moral issue, they know no US city will suffer retaliation from Iran, Syria, Venezuela, Cuba, etc...

And if it ever happens, it will be 9/11 again - they'll likely go 200% fascist

That last part is very important to understand.

There is no scenario where a regime change war waged by the US leads to a democratic transition for Iran.

It's either the same regime with minor changes in leadership and policy, or a power vacuum that leads to a civil war and long term instability.

Já quero! Eu acho que O Feiticeiro de Terramar é o livro que eu mais comprei cópias para presentear. A Ursula é provavelmente a autora que eu mais comprei livros variados para presentear meus amigos de um modo geral…

For CNN, a Change in Ownership Means a Suddenly Uncertain Future

There's nothing "uncertain" about it. Larry Ellison is building an autocrat-friendly propaganda machine and whatever shaky journalism originated from this place will soon be dead.

O número de imagens sem descrição subiu consideravelmente na timeline, então farei aqui o nem tão habitual lembrete.

Descrevam suas imagens e vídeos, por gentileza, se possível, se caso não for dar muito trabalho e ou cair uma mão.

Inclusão promove convívio, abre espaços.

Nature study: "The political effects of X’s feed algorithm"

Abstract: "Feed algorithms are widely suspected to influence political attitudes. However, previous evidence from switching off the algorithm on Meta platforms found no political effects1. Here we present results from a 2023 field experiment on Elon Musk’s platform X shedding light on this puzzle. We assigned active US-based users randomly to either an algorithmic or a chronological feed for 7 weeks, measuring political attitudes and online behaviour. Switching from a chronological to an algorithmic feed increased engagement and shifted political opinion towards more conservative positions, particularly regarding policy priorities, perceptions of criminal investigations into Donald Trump and views on the war in Ukraine. In contrast, switching from the algorithmic to the chronological feed had no comparable effects. Neither switching the algorithm on nor switching it off significantly affected affective polarization or self-reported partisanship. To investigate the mechanism, we analysed users’ feed content and behaviour. We found that the algorithm promotes conservative content and demotes posts by traditional media. Exposure to algorithmic content leads users to follow conservative political activist accounts, which they continue to follow even after switching off the algorithm, helping explain the asymmetry in effects. These results suggest that initial exposure to X’s algorithm has persistent effects on users’ current political attitudes and account-following behaviour, even in the absence of a detectable effect on partisanship."

New experimental study publshed in Nature confirms what we all largely expected, that "X" was algorithmically redesigned to promote a right-wing ideological pipeline.
