Perfect Days (2023) · Wim Wenders

今天适合看《Perfect Days》,因为它更像一次生活和判断方式的校准,能把注意力从持续输入里稍微抽出来,重新放回你真正想怎样生活和做事上。

Insight

今天的输入更像几股不同语气的材料同时挤在一起:社区链接在暴露工程和产品环境里的真实焦点,长视频在把这些焦点放回更完整的语境里,研究材料则提醒人热度和可落地性并不总是同一件事。如果先不急着做结论,至少可以把这几条线索放在一起看:Hacker News 的 The Little Book of Generative AI Foundations: An Intuitive Mathematical Primer;Hacker News 的 Safari introduces Adaptive Dark Mode in 27.3;Hacker News 的 The Internals of PostgreSQL;Hacker News 的 Jailbreaking my car's navigation system just so I can change the time;Hacker News 的 Stringman, an $800 open-source room scale gripper robot;Hacker News 的 Show HN: HackerTV – HN's most-recommended Youtube videos as 24/7 TV channels。真正值得注意的不是单条内容本身,而是它们共同指向了什么、彼此漏掉了什么。

Runway's first AI film in 2019 was 128x128 pixels. Today, people can't tell generated video from real footage. Runway co-founder and CEO Cristóbal Valenzuela explains how next-frame prediction at scale teaches models physics, object permanence and how the world works. He then shows what happens when those models become real-time and interactive: world interface models, robotics, and Continuum, an early research prototype where anything on your screen can become a live, interactive video. 0:00 Intro 0:50 Runway's first AI film (2019) 1:49 State-of-the-art video today 2:48 Video as next-frame p
