of course this rabbit hole goes deeper, and we have a paper using this technique for string constraint solving that i’d love to derail this post into, but i’ll save that for another time. the main point is that symbolic derivatives are a more powerful and efficient generalization of Brzozowski’s original idea, and they form the core of the new RE# engine. fun fact: symbolic derivatives are also implemented in Z3 (the SMT solver) for its sequence theory - so in some sense we’re inching closer to having an SMT solver’s core machinery inside a regex engine.
性能的孱弱同样也体现在日常使用的流畅度上，不过得益于至少给了8G LPDDR4X内存，至少不会出现因为可用内存太低导致频繁出发LMK杀后台应用的情况。不过桌面滑动则经常无法稳定120帧，应用冷启动更是强制锁60，导致了巨大的卡顿实感，而更新了Android 15大版本后联想甚至把这机器的冷启动非线性动画直接砍了，待遇还不如自家更便宜的G系列新机。在安装大型游戏时，安装速度也明显慢于芯片性能更高的机型。另一方面由于只支持WiFi-5，游戏下载时基本也只能跑到8-9M/s，网速体验只能说凑合。

The Eureka police department in northern California said in a news release last Thursday that on 21 February, officers and Humboldt Bay fire personnel were dispatched to a motel on the 4000 block of Broadway Street in Eureka – identified by the Eureka Times-Standard as the Lamplighter Inn – after receiving a report of “two unconscious patients due to a possible drug overdose”.。关于这个话题，新收录的资料提供了深入分析
