In 1996, Brewster Kahle wrote "Preserving the Internet" for Scientific American. Nearly 30 years later, it’s striking how many of his predictions about digital preservation came true—and how many challenges remain.

We ran a randomized controlled trial to see how much AI coding tools speed up experienced open-source developers.
The results surprised us: Developers thought they were 20% faster with AI tools, but they were actually 19% slower when they had access to AI than when they didn't.

Banir smartphones das escolas tem pouco ou nenhum impacto no bem-estar
Banir a utilização de smartphones por crianças e adolescentes é ignorar que estas têm acesso a diversos tipos de dispositivos, tanto na escola como em casa.
