At the heart of BuildKit is LLB (Low-Level Build definition). Think of it as the LLVM IR of build systems. LLB is a binary protocol (protobuf) that describes a DAG of filesystem operations: run a command, copy files, mount a filesystem. It’s content-addressable, which means identical operations produce identical hashes, enabling aggressive caching.
家门口的集市对冬来说像捡到了宝，去县乡他最爱逛当地集市。来矿区之前，他就说，到那边做各种好吃的。到现在还没见怎么做，倒是图方便买了不少现成的：海鲜、卤肉、烧饼、炒栗子……回来自己倒杯威士忌，吃得挺美。海鲜买自海鲜基地，叫基地，其实就一个门脸。矿区地方小，没多少人吃海鲜，我一般不进门，冬进去买。我做惯了甩手掌柜。如果不是冬，好多东西我都不知道会不会去吃，比如大闸蟹。听上去，我穷得可以，倒确实也没富过，其实主要是怕麻烦。母蟹肚子是完整的白壳，公蟹肚子上像有口钟，或是塔。意思是，要想横着走，必得当个托塔天王，还得坐如钟。我第一次吃蚕蛹，也是冬买的。我很长时间都对牛奶不耐受，小时候没喝过，到了高中，第一次喝酸奶。小汽车也是高中第一次坐，连车门也不会开，教我开车门的是个小屁孩儿。记忆中不少这种鸡零狗碎的事。

She also confirmed that part of the company's response will be price increases. Samsung similarly warned of potential price increases due to AI-induced memory shortages.
