程序员所说的「正则表达式」，与形式语言理论语境下的原始「正则」概念，几乎没有共同之处。正则表达式（至少是 PCRE）可以匹配所有上下文无关语言，因此还可以匹配格式正确的 HTML 和其他几乎所有编程语言。正则表达式至少可以匹配某些上下文相关语言。正则表达式的匹配是一个 NP 完全问题。因此，可以使用正则表达式解决其他任何 NP 问题。

I appreciate driving as a long-overdue addition to my options, a distinct one that furnishes a precious space of mindfulness, whether accompanied or alone.

It would be fun to see how I, at some point in the future, would think of this specific iteration of my aesthetic and epistemology.

价格摆在这，对 R02 本来也就不该有更高的期待。但在形而上的层面，它的启示意义是在这个平台闭锁的时代，演示了一个对用户友好的穿戴设备本可以是什么样——别太聪明。愿明日之域中，竟是蠢货之天下。

之所以会关注到 Smart 5C，最初只是因为一个非常庸俗的理由：它的 8GB 内存实在是有点……大方？

Bon voyage, and the rest is mystery.

Apple is a for-profit that is capable of and responsible for its own decisions of whether and how to comply. On the other hand, users can vote with their wallets. What’s more intriguing to me, though, is how Apple manages this growing set of regional feature restrictions.

Plus, since it’s a reader meant to be read non-sequentially and piecemeal, carrying it in its 600-page physical form seems to defeat the purpose. That was when I thought of the book scanning services I had heard about in the past and decided to try 1DollarScan.com, a service mentioned in multiple Hacker News threads.

往年苹果文案的翻译经常有一些「语出惊人」的地方，这两年似乎收敛了不少，但还是保留了每次看新品文案对比几版翻译的习惯。这里摘录美国官网原版和中、港、台版本翻译对此（方法见结尾），并就自己注意到、觉得值得一提的若干译法作出评论。观点仅供参考，欢迎批评。

What’s fascinating about Dinesen’s storytelling is the labyrinthine structure and fractal logic. Typically, you start with a narrator who encounters others telling stories-within-stories; the narration keeps branching out until, just as the mass is about to become a mess, a ray of revelation cuts through, shockingly and cruelly exposing the underlying interconnections. Concurrently, through the constant creation and piercing of personae, and the alternating misreading and projection by others, issues of identity and subjectivity surface.
