软件层面的iPhone时刻迟迟未至，为何头部玩家都将目光投向了螺丝、芯片与流水线？
this limitation has a purpose - it allows us to have a more efficient matching algorithm implementation, which i don’t think is immediately obvious and i don’t think even experts in the field fundamentally “get” this. before you “fix” the problem and turn my linear matching algorithm into a quadratic one, make sure you thoroughly understand why we have this limitation. the reason is that we have only one “kind” of match, and marking the end of the position is always correct. with arbitrary lookarounds, instead of marking the match ended here, you would have to mark the match for lookaround #7 ended here, and the match for lookaround #3 ended 5 characters ago, and the match for lookaround #12 ended 100 characters ago. i had a lot of temptation to support arbitrary lookarounds, and it really does seem like an easy fix at first glance, but the complexities arise much later in the match loop, and this is a good example of how some theory just does not hold up when you implement it. as a side note, we can actually loosen this restriction on R3 (above) which is still work in progress, but not R1, because R1 is the one that determines the start position of the match.

The stakes, Karp argued, go well beyond any single Pentagon contract or any single company’s policy decision. “The danger for our industry,” he warned, “is that you get a famous horseshoe effect where there’s only one thing people agree on—and that’s that this is not paying the bills, and people in our industry should be nationalized.”，详情可参考PDF资料

В ночь на 3 марта посольство Соединенных Штатов в Саудовской Аравии было атаковано двумя беспилотниками — предположительно, иранскими. Кроме того, Иран ударил баллистическими ракетами по военным базам в Бахрейне, Катаре и Кувейте.
