16.67万个果蝇神经元刚刚接管了3架无人机，没人教过它们怎么飞。 科学家绘制了一只真实果蝇的完整大脑，每一个神经元以及全部2500万个连接，并免费放到了网上。 把这个大脑复制了3份，每份接入一架无人机。 没有飞行代码，没有手势预设，没有“避开椅子”的规则，只是摄像头把画面喂给果蝇的眼睛，神经元直接控制油门。 一架悬停，一架从椅子旁滑过，一架落到地板上并稳住。 这个大脑花了3.5亿年学习如何待在空中，现在它又回到了属于它的地方。 没有GPU，没有训练过程，没有千亿美元的数据中心，只是一颗像糖果粒一样的大脑。 一只苍蝇给你3个飞行员，1000只苍蝇给你一个机群。 苍蝇死了，但它的大脑刚刚拥有了一支中队。

MIT has a free 650+ page textbook that teaches you how to think like a computer scientist. It's called Structure and Interpretation of Computer Programs, and it costs $0. Most people think "learn programming" means learning Python or JavaScript, picking up a framework, shipping a side project, and grinding Leetcode. But under every great programmer is a way of thinking about problems. Recursion, abstraction, modularity, language design that's the actual skill. This is what MIT used to teach in its very first CS class for over two decades. It covers: Procedures and abstractions Higher-order functions Recursion and iteration Data as procedures Symbolic differentiation Streams and lazy evaluation Local state and mutation Metalinguistic abstraction Writing your own interpreter Compilation Register machines Basically, the stuff that turns you from someone who writes code into someone who understands what code really is. You don't need to be enrolled at MIT, pay tuition, know Scheme, or have a professor. Read the whole book online today. Link: web.mit.edu/6.001/6.037/sicp…

An open-source robot vacuum you build yourself — Raspberry Pi, ROS 2, 2D LiDAR, Home Assistant, 3D printed chassis. No cloud, fully local. oomwoo is early stage and building in public. The community can contribute modules in parallel — from SLAM navigation to dust bin design. makerspet.com/blog/building-… #ROS2 #RaspberryPi
