On the evening of 17 September 1908, a young American officer named Thomas Selfridge climbed into a fragile wooden aircraft at Fort Myer, Virginia. Minutes later, he would become the first person in history to die in the crash of a powered airplane.
First, modern compilers work from this first principle. LLVM's main challenge is to merge, traverse, and select a sequence of instructions so that we have the least computation time (usually on a single core). MLIR aims to unify lowering across heterogeneous hardware targets, especially when the hardware supports domain-specific operations like convolution, matrix multiplication, and precision conversion. (MLIR is the next planned series to dive in.)

整段回答裡，美國和以色列始終沒有被點名，王毅的批評通過原則包裹：它反對的不是某個具體國家的具體行動，而是「武力邏輯」這種更宏觀的國際政治取向，看起來是一種有意為之的留白。
I’m not going to go into the depths of caching in pull-based reactivity, but as the famous aphorism reminds us, one of the hardest things in computer science is cache invalidation. And typically, the more efficient a cache is at reducing work, the harder cache invalidation becomes. So an easy approach might be generation counters, where every time we change any input, all cached values are invalidated immediately, and a harder approach might be an LRU cache of all a node’s dependencies where we need to consider how many entries to cache, and how to determine equality3.
