With primitives focused on different ways of moving the data and looking through it, code that would take a lot of lines can be significantly reduced down at the expense of being more terse to the average onlooker.

因此，在非紧急非危险的救援中，引入商业化力量就颇有必要。实际上，在非紧急的状态下，商业化的向导都足以帮助仅仅是恐高或腿脚不便的客户及时识别风险、确定下撤路线，遑论训练有素的商业化救援团队。在能力匹配、自负其责的前提下，人们对野山的探索完全可以由商业化救援与保险来补上权责拼图，长远来看也可让公共利益与个人自由各得其所。
The segmentation and paging scheme of x86 processors has been discussed extensively elsewhere (see the OSDev wiki, the Writing an OS in Rust series, or the Intel 386 Programmer's Reference Manual, Chapter 5). Here I'll focus on what the actual silicon does to make it fast.，详情可参考whatsapp
One thing that allowed software to evolve much faster than most other human fields is the fact the discipline is less anchored to patents and protections (and this, in turn, is likely as it is because of a sharing culture around the software). If the copyright law were more stringent, we could likely not have what we have today. Is the protection of single individuals' interests and companies more important than the general evolution of human culture? I don’t think so, and, besides, the copyright law is a common playfield: the rules are the same for all. Moreover, it is not a stretch to say that despite a more relaxed approach, software remains one of the fields where it is simpler to make money; it does not look like the business side was impacted by the ability to reimplement things. Probably, the contrary is true: think of how many businesses were made possible by an open source software stack (not that OSS is mostly made of copies, but it definitely inherited many ideas about past systems). I believe, even with AI, those fundamental tensions remain all valid. Reimplementations are cheap to make, but this is the new playfield for all of us, and just reimplementing things in an automated fashion, without putting something novel inside, in terms of ideas, engineering, functionalities, will have modest value in the long run. What will matter is the exact way you create something: Is it well designed, interesting to use, supported, somewhat novel, fast, documented and useful? Moreover, this time the inbalance of force is in the right direction: big corporations always had the ability to spend obscene amounts of money in order to copy systems, provide them in a way that is irresistible for users (free, for many years, for instance, to later switch model) and position themselves as leaders of ideas they didn’t really invent. Now, small groups of individuals can do the same to big companies' software systems: they can compete on ideas now that a synthetic workforce is cheaper for many.
