At the Lean FRO, Kim Morrison, a Senior Research Software Engineer, recently ran an experiment that went well beyond our expectations. An AI agent converted zlib, a widely used C compression library embedded in countless systems, to Lean, with minimal human guidance. No special tooling was built. It was Claude, a general-purpose AI, with no special training for theorem proving, out of the box. The workflow had four steps. First, the AI produced a clean, readable Lean implementation of the zlib compression format, including the DEFLATE algorithm at its core. Second, the Lean version passed the library’s existing test suite, confirming behavioral equivalence. Third, key properties were stated and proved, not as tests, but as mathematical theorems. The capstone theorem:
Despite that, the MacBook Air’s displays are plenty vibrant. Both models come with a Liquid Retina LED panel at 224 ppi, and emit up to 500 nits of brightness. It makes working outdoors possible, but since it’s a glossy panel, I’d still recommend staying inside (or finding shade). The MacBook Air 13 has a 13.6-inch, 2,560 x 1,664 panel, while the 15 is equipped with a 15.3-inch, 2,880 x 1,864 screen. I’ve seen both the 13-inch and 15-inch versions of the MacBook Air M4 in person and they’re pleasantly bright.，推荐阅读咪咕体育直播在线免费看获取更多信息
