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:
Чтобы избежать этой проблемы, Презант посоветовал во время мастурбации чередовать более легкое и более сильное давление, менять длину движений и варьировать темп, а не придерживаться постоянной высокой интенсивности.

在此之前，美国的债务走势遵循一个相对简单的模式：战时上升，战后偿还。独立战争后，1791年美国积累了7547万美元国债，然后逐步偿还。南北战争是一次量级跳跃，国债从6500万美元飙升至27亿美元，增长将近40倍——但战后几十年间，这笔债务也大幅压缩了下来。19世纪的美国政府，有战有还，债务像呼吸一样有张有弛。，更多细节参见safew官方版本下载
全国性反政府示威勉强平息还没多久，核心军政高层又集体身亡，这是1979年建立至今的伊朗伊斯兰共和国最严重的动荡。事到如今，对内有待迅速恢复政治秩序，对外急需应对军事打击。伊朗接下来的每一步，都会深刻影响本国、地区乃至世界政治的走向。
