眼泪
听到2岁多的小女儿哭闹着要巧克力，我赶紧走过去。
她边抽噎，边在我手上放了一块粘粘的东西，说：“爸爸，这是我的眼泪。”
定睛一看，原来是一坨鼻屎。
The ADHD Algorithm: From Dijkstra to SSSP
In 2025, computer science witnessed one of its most dramatic plot twists. Professor Ran Duan's team at Tsinghua published "Breaking the Sorting Barrier," demolishing a 50-year-old assumption about shortest path algorithms. The timing was almost comedically perfect—just one year after FOCS had awarded its best paper prize to research proving the "Universal Optimality of Dijkstra." From mathematical perfection to mathematical revolution in twelve months flat. For most people, this academic drama might seem abstract. But for those of us navigating life with ADHD, these two papers accidentally outlined the most effective time management system we never knew we needed. Main takeaways: Dijkstra Algorithm - Dimensionality Reduction : Remove the time dimension from project planning, which ADHDers struggle with most. SSSP Algorithm - Pruning : Prevent decision paralysis and overthinking by eliminating irrelevant choices. Universal Optimality - First Principles : Mathemat...
