本周推荐：《树的秘密伙伴》

作者：詹姆斯·纳迪 (James B. Nardi)

译者：戚译引

推荐：小编1号

如果你慢下来没有什么目的的看路边的一棵树，你会发现它有很多“小伙伴”。蚜虫、毛毛虫、甲虫、蜂、蝇、蝶、鸟、甚至有时候会看到松鼠。这些平时赶路时候注意不到的小小世界，在这本书里得到了充分的展示和描述。作者在没有什么铺垫的情况下就展示了生物界残酷的一面，例如看似悠闲的毛毛虫可能已经体内被植入了一种蜂或蝇的幼虫，沦为了移动的生鱼片；有些小生命则演化出了神奇的技能，让我第一次看到的时候满脑子惊叹号“这也行？！”以及强烈的怀疑这几乎不可能是大自然盲眼的演化。一切都过于严丝合缝，充满了高等智慧的谈判和协商感。

或许以后的AI也会这样看我们吧。

北美 2026 年 LLVM Developers Meeting 的报名截止日期为 10 月 16 日。
Bruno Cardoso Lopes 分享了 9 月 ClangIR 进展报告。47 个 SPEC CPU 2026 benchmark 中有 40 个可以编译并通过，2 个链接失败，5 个出现运行时失败（miscompile）。
【我们用英文翻译的怎么看】Nikita Popov 提议修改 LLVM 的 AI 工具政策，禁止 AI 生成的交流内容，目的在于阻止人们提交由 AI 工具撰写的 PR 描述与 RFC。
Tom Stellard 就我们在 GitHub UI 中合并 pull request 失败这一项目级问题发布了一则 PSA。这是一个非常令人沮丧的状况。希望 GitHub 能尽快修复。
Mitch Briles 发起了一场 RFC 讨论，关于在后端中尊重 freeze 语义。"AArch64、AMDGPU、RISC-V 和 X86 上的 SelectionDAG、FastISel 以及 GlobalISel 选择器都无条件地把 freeze/ISD::FREEZE/G_FREEZE 降低为 COPY。如果 freeze 的输入是 undef 或 poison，剩下的就是 IMPLICIT_DEF 的一个 COPY，而它表示一个 undef 值。ProcessImplicitDefs 与寄存器合并器随后把这个 COPY 视为未定义，于是不同的使用点就可能读到不同的寄存器。其后果就是由来已久的一系列 miscompile。"
Yaxun (Sam) Liu 发布了一则 RFC，关于为 llvm-cov 增加一个可选启用的选项，以便在覆盖率报告中排除被标注的源码行与区间。
Kunal Chadha 希望新增一个属性，用于标示函数对某个指针参数所写入的字节区间。

本周推荐：《创新者的窘境》

作者：克莱顿·克里斯坦森

译者：胡建桥

推荐：小编1号

这是最近听黄仁勋等一些目前世界上市值最高的公司CEO或者财富最多的人的一些访谈聊到的一本书。囫囵吞枣的看了下，并没有看到什么让现在的我鹈鹕灌顶的事情。很有可能是时机未到。这本书对于已经是在某一个行业处于领先或者主导地位的大公司是非常有警醒作用的，大公司最害怕的就是被创新企业破坏性颠覆了。而处于创新企业或者小公司的时候，其实感觉不到里面的各种逻辑——当然，如果感觉到了，按么恭喜你获得了一份新的“创业鸡血”。

我也好想有一天能够站在那样的高度带着那种担心啊。一方面觉得 AI 要颠覆一切，很恐慌；另一方面又觉得自己可以用 AI 实现巨大的突破，很亢奋。

本周推荐：《最好的告别》

作者: 阿图·葛文德译者: 王一方、彭小华（主编）

如果你已经成年，父母还健在，刚刚有孩子或者即将有，那么，是时候翻开这本书了。

这本书的主题略沉重。非常的沉重。人生最大的沉重或许就在本书中了。

所以很难拿起来。2020年10月28日，OSDT Weekly 第69期的时候我推荐过一次，但是相信很多人并没有真的翻开过。

但是，一旦你知道了这本书的存在，那么总会有一个契机让你翻开第一页。每当面对人生的重大改变，这本书或许都可以作为你的“拐杖”，让你知道，你并非一个孤立的个体。

只要翻开就好。无法承受的时候就放下来，不用勉强。再次准备好的时候，或许会有更好的告别。

这本书改变了小编1号的对人生的观念。如果也改变了你的，让你看到之前未曾看到的美好，那么我会感到欣慰。

【开源自荐】NanoAvatar：在 Android 手机上本地生成语音驱动的数字人视频，无需云端 GPU。支持流式生成，已发布 Android 与 Web 推理源码、模型权重和可安装 APK。演示 · 模型权重 · Android APK
【开源自荐】OrcaReplay：面向命令行的 AI agent 运行录制 / 重放工具。orca 以 HTTP 代理的形态夹在开发者的 agent 程序与模型服务之间，把一次运行的全部流量（prompt、工具调用、响应、原始字节）原样录到本地 trace，之后可在不联系任何远端服务的前提下重放这次运行、diff 两次运行的差异，或把录像 fork 到另一个模型上重跑。独立 CLI（Node 20+，npm i -g orcareplay，Apache-2.0），trace 留在本地磁盘，无托管服务、无日志外发；另提供 orca mcp 六个工具（list/show/checkpoints/graph/replay/compare）读取本地 trace 库。
【开源自荐】YYLO：面向命令行的 AI 编码 agent 编排 CLI（yylo / yy，Node 20.10+，npm i -g @yylo/cli，MIT）。它把「让 agent 改一次代码」变成有边界的流程：task start 为每个任务冻结目标 SHA、创建独立分支/worktree，产品改动只发生在任务 worktree；finish 独立校验范围、脏字节、运行时与项目检查，通过后入队但不自动合并；merge land 在私有 detached candidate 里合成，配 Git expected-old ref 保护——合并阶段不启动模型、不选 reviewer、不排测试，测试与评审是合并之外的显式项目检查。全程留有回执（receipts：stdout/stderr、session ID、声明的哈希），agent 跑过什么、改了什么事后可查；另有 ypl（yy pi --live）交互式终端 agent 会话。

我真是爱死这本书了，强烈建立在上班中午吃饭的时候看。封面就是一个红色的很Q的大便。作者是一位研究肠道菌群的专家，会告诉你很多虽然可能没什么实际的用途但是一定可以让你在下一次聚会吃饭的时候显得很博学的知识。

比如你每天拉出来的大便，其实只有三分之一是吃下去的食物残渣；还有三分之一是大肠黏膜脱落物——Yes。

另一个无用冷知识：另外作者的名字的日文发音，跟日文里的大便是一个音，以至于很多人第一次见面以为是为了事业献身取的笔名。

在美国，国内有伙伴去么？ 2026 年 LLVM 开发者大会(LLVM Developers' Meeting)的日程安排已经公布。
又有一批 EuroLLVM 演讲视频已上传至 YouTube。
因特尔也是好起来了： Michal Paszkowski 及其同事提议将 PISA 后端上游合并到 LLVM。PISA(Portable Instruction Set Architecture,可移植指令集架构)是一种为新一代 Intel GPU 设计的虚拟 ISA。该后端完全使用 GlobalISel。
这个会不会重新做一个轮子： Raphael Isemann 发起了一个 RFC 提案线程,讨论让 LLDB 摆脱使用 Clang AST 和类型系统的 TypeSystemClang,以构建更快、更可靠的 C 语言类型系统。
MLIR的新闻太多了，要整理也不容易：沉寂一段时间之后,Javed Absar 的 MLIR 新闻通讯回归了。如果你想了解 MLIR 近期的 RFC 提案和变更,这里是最好的去处!
裸机也能做AS么？ Schrodinger Zhu 发起了一个 RFC 讨论,主题是面向裸机(bare metal)环境的 address sanitizer。
干得漂亮：为 SpacemiT-X100 RISC-V 内核添加了向量调度信息。00312bb。
改进了 LLVM 的 CMake 构建系统对增量文档构建的处理方式,不再遗留过期的文件。263280e。
还有伙伴在用么？移除了 loop-extract pass,因为上游已没有任何地方使用它。8277177。
新增了 llvm-gsymutil --statistics 选项。668134e8。
荣誉！为 XiangShan KunMingHu RISC-V 微架构添加了调度器定义。fa01521。

本周推荐：《那些活了很久很久的树》

作者：菲奥娜·斯塔福德

译者：王晨、王位婷

推荐：小编1号

可以说这是一本跟你的日常生活完全不会有任何联系和“用途”的书。看了这本书不会增加你的知识或技能，不会让你的经济收入增加，不会让你的身体更健壮。

而这真是我喜欢这本书的地方：这种在功利交付完全无意义的阅读，构成了我纯粹悦己的确认。虽然对于赚钱没有什么用，但是真的好有意思啊！不管是古代的西欧神话、还是英国的流行作家，抑或是俄罗斯战斗民族的歌曲中，都有人和树木的情感联系和寄托。

而我，作为一个中华文化熏陶培养起来的80后，看到有意思的地方，总是忍不住觉得有人在我的耳边低语：

”一棵是枣树；另一棵也™️是枣树。“

这些术语确实不好翻译成中文： Luke Lau proposes adding an llvm.mask.beforefirst intrinsic that the loop vectoriser would use for generating exit masks use during early exit vectorisation. The second half of the RFC muses on when it's worthwhile introducing a new intrinsic.
这个patch貌似巨大，宋教授站出来进行了一个详细的讨论，认为这个有很多地方都需要重新审视。 Shilei Tian started an RFC discussion on link-time finalisation for separately compiled AMDGPU device code. “我们提议在 LLVM 中构建一种架构，以支持 GPU 设备代码的可扩展独立编译，并以 AMDGPU 作为首个实现目标。独立生成的设备目标文件（device objects）可包含针对各个函数的资源信息；然而，内核（kernel）的最终资源需求取决于从其他设备目标文件中选取的定义以及这些设备函数所需的资源。因此，只有在完成最终的目标文件链接解析后，才能确定完整的资源需求。本 RFC 首先阐述了这一通用的最终确定（finalization）需求，随后提出了一种 AMDGPU 实现方案，该方案在常规 ELF 链接过程与 AMDGPU 专属的资源分析逻辑之间定义了一个精简的接口。”
巨大改进： The RISC-V backend learned to deduplicate frame base address materialisations for large stack frames, leading to an 18% performance improvements on SPEC CPU 2026 'cactus' benchmark on the SpacemiT K3. 4120b5f.
LLVM确实需要： Documentation was added for self-hosted runners on GitHub. 0fa9cfa.
好看么： The Furo theme is now used for LLVM documentation. You can see it in action here. c44443f.
新的扩展又双叒叕出现了： MC-layer and codegen support was added for the experimental RISC-V Zilx (indexed integer load instructions) extension. 23a2224, 8a1ff7f.

本周推荐：《囚徒健身》

作者：保罗·威德

译者：谷红岩

推荐：小编1号

这本书有点年头了。称赞这本书的和批评这本书的都大有人在。知乎上也有一些比较深入的健身人士的观点可以借鉴。书中对于器械健身等方式的批评也引起了不少的批评和否定。

但是，如果你是一个身体条件不怎么样的、但是又感觉要开始关注身体健康的人，那么这本书可以给你一个很好的自信的起点：那就是可以完全不用理会现在社会上各种健身房和健身视频渲染的焦虑，踏踏实实从没有任何器械投入和和健身费用投入上开始。

本书以开始的练习都是反复提醒从最简单的开始练，是真正的所有人都可以起步，例如站立状态对着墙的“俯卧撑”，我这种菜鸡也可以做50个一组，之后会感觉有点肌肉酸胀，有种运动了的快乐。一步一步来，坚持是最重要的。

这本书也是网上到处都有，微信读书也有，可以说真正的0费用门槛、能体能门槛了。哪怕只看了第一个动作，别逞强，从最简单的一个对着墙的“墙卧撑”，也是有帮助的。

作者：李开复

推荐：小编1号

强烈推荐所有人都阅读李开复老师的这本书，有非常贴近现实的思考和冲击案例，也面向不同的人群给出了清晰的建议。我已经开始用起来了书中的一些方法论（实际上也偷懒直接用了里面的一些个人经验照搬）。现在我在AI快速发展的当下，更加自信一点了，并且充了500块钱DeepSeek开始新一轮折腾。

本周推荐：《如此打工30年》

作者：占有兵

推荐：小编1号

带给我非常多小惊喜的一个作者。从1995年开始，到南方打工，各种生活的细节，都记录下来。那个时候我记得还是没有数码相机或者智能手机（那是20年之后的事情了），但是作者很有动力和毅力的保留了非常多当时的原始小票、证件、收据、手写便笺等，并留下了令我惊叹的日常生活的照片。那应该还是胶卷的时代，胶片贵，打工的钱很少，坚持下来非常不容易。文字的部分简短朴素，没有AI味道的朴素让我非常的沉迷，而简单文字中描述的每个人的小故事又时不时让我惊心动魄。

图书的简介中提到作者拍摄了超过150万张照片，打工相关的实物资料超过6吨。也得过很多照片的奖。还举办过照片的作品展出。

我很开心能够遇到这本书，让我能够仿佛沉浸在作者的环境中体验我没有体验过的30年。

本周推荐：《咸的玩笑》

作者：刘震云

推荐：小编1号

刘震云写的故事，文字有很明显的风格：都是短句子。而且自从看过了刘震云的访谈，我脑子里看到《咸的玩笑》里面故事的时候，总是会自动脑补出来刘震云口述的声音来。很口语化，简短，看起平常，道尽一个人又一个人的生活。

看了一段时间之后我会变得对自己的生活感受更加释然，就好像是旁观故事里的人物一样开始旁观了自己，专注地期待着，不会想起来要去看看手机。

本周推荐：《苏东坡传》

作者：林语堂

译者：张振玉

推荐：小编1号

通过这本书第一次系统性的看到了苏东坡（还有他爸和他弟）的一生。我一开始满脑子想的都是古代人连抗生素都没有是如何能够长寿到60岁以上的。或许乐观是一个很重要的原因。当然也是幸存者偏差，因为苏东坡的第一任妻子在26岁就已经过世。也是十年之后，苏东坡写下了那首我至今能背诵出来的“十年生死两茫茫，不思量，自难忘……夜来幽梦忽还乡，小轩窗，正梳妆。相顾无言，惟有泪千行……”

还有一个令我很开心的，是作者提到，苏东坡在杭州的时光，是他生平最快乐的时光。公馆位于凤凰山上，可以看到钱塘江和西湖。苏东坡的才华、浪漫和热情，与这个城市完美的拥抱在了一起。千年之后，这座城市依然享受着东坡先生的文化遗产。

以后爬凤凰山的时候，就有更加丰富的感受了。

今年有人计划去美国的 LLVM 开发者大会么？ The call for proposals is now open for the 2026 US LLVM Developers' Meeting, closing on July 14th. The Dev Meeting itself will take place on October 26th-28th in Santa Clara. Additionally the set of workshops has been announced, registration is already open, and applications for student travel grants are open.
这个技术点很难： Nikita Popov proposed an allocator provenance model. "We model memory allocation as 'creating' provenance and memory deallocation as 'destroying' provenance. This is reasonably well-defined in cases where the implementation of the allocator lives in a different module. However, it becomes unclear what exactly these terms mean when the allocator is visible in the same module. This RFC is an attempt to specify the provenance semantics of allocators in LLVM, and provide the means to correctly handle them even if asymmetrically inlined."
国内也有一些伙伴在贡献： Bruno Cardoso Lopes provided another status update on ClangIR upstreaming. An -fclangir-built clang can now compile about 93% of the translation units in the clang build graph (although the correctness of the compiled TUs has not been tested!).
招募维护者： Nikita Popov is querying if anyone is using the IROutliner and would step up to maintain it, in order to prevent it being removed.
支持： Vittorio Burani started an RFC Discussion on upstreaming support for the RISC-V OpenHW Group Core-V XCV vendor extensions as implemented in the CV32E40P core.

作者：日本NHK特别节目录制组

译者：高培明

推荐：小编1号

一开始以为是讲日本年轻人之间的不交流不恋爱，结果翻开之后大受震撼：本书讨论的是现在被称为“孤独死”的现状。不仅讲述了有关死亡后无法找到家属的情况，还描述了一个又一个人老死之后，没有家属愿意认领骨灰的情况。作者团队像是侦探一样刨根问底，去找到各种逝者存在过的痕迹。

我个人一直认为日本社会的种种现象在很多方面可以作为一种我们未来的可能性展示，包括全世界都有陆续出现的老龄化/少子化、死后无人继承遗产等问题，都有着陆陆续续的出现。通过这本书的阅读，或许能够有一些很好的洞察。

作者：斋藤环

译者：Homura

推荐：小编1号

作为喜欢看动漫的小编，确实注意过很多动漫都是以美少女作为战斗英雄和主要角色出现的，从小时候看的《美少女战士》、《新世纪福音战士》到《风之谷》、《少女终末旅行》，各种角色都有。这本书是少有的让我看到标题就买下来的小册子，觉得肯定好看。认真看了之后发现还是有点社会研究的感觉的，作者尽力尝试建立一个经验理论体系了。

看到里面很多熟悉的角色，就仿佛回顾了自己的一生一样（乐）。

本周推荐：《长安的荔枝》

作者：马伯庸

推荐：小编1号

小说篇幅不算长，故事大背景在唐代，小环境内容非常切合现在打工人的描述，非常有代入感了。已经被改编成了同名电影，口碑也还不错。

这本书有两个地方我在写推荐的时候非常有感触：第一点是主人公发现了杨国忠如何假借皇权沿路搜刮，并形成制度性的吸血机制，后背发凉。这既贴合了教科书中的各种刻板描述，不算意外，但是又让读者在经历了“面对困境-寻找和受挫-创造性解决-升华回顾”的励志叙事中当头一棒。

第二个地方，是当主人公第二次回到岭南的时候，当地人问他之前说要带的酒啊吃的啊带了没有。那一瞬间主人公的感受，我作为读者都觉得感受到了。这种对话太熟悉了，而我在阅读到后半段的时候，真的跟主人公一样，忘记了。

得看看： Nikita Popov made a proposal, 'yet another strict FP'. "I believe that if we want to improve on the current strict FP situation, and treat strict FP as more of a first class citizen, we need to avoid further half measures, and actually support first-class FP environment annotations on all floating-point operations, including basic FP instructions." This proposal was move the IR from something like %res = call float @llvm.experimental.constrained.fadd.f32(float %a, float %b, metadata !"round.dynamic", metadata !"fpexcept.strict") to %res = fadd float %a, %b fpenv(rounding_mode: dynamic, strict_except: true, ...).

本周推荐：《龙与洋鬼子：一位瑞典地质学家眼中的万象中国》

作者：安特生

译者：李雪涛

推荐：小编1号

最近微信读书推荐的民国的书籍变多了些，这本书的作者精力也是颇具“穿越”色彩。作为一个瑞典考古学家，来到了民国时期的中国，进行考虑，还受雇于北洋政府，跟袁世凯见过面。北京猿人、仰韶文化等发现都有作者的参与或主导。

所以阅读本书就时不时有一种年代缝合感，九年义务教育中已经忘记差不多的历史、地址、政治、语文知识，通过一个具体的老外考古学家串在了一起。

本周推荐：《日本在华的间谍活动：1932～1936》

作者：万斯白

译者：文缘社康狄

推荐：小编1号

这位万斯白来自意大利，跟美国的万斯没有任何关系。每一位渴望和平的人都应该阅读的书。作为一个中国人在阅读这本书的时候的情感是很混合的：一方面，书中描述的大的历史事件和时间脉络在历史书籍中都有描述以至于显得是在陈述简单的常识；但是书中作者亲身经历的时代和个人感受，又让我看的后背发凉。看完几页之后，可能你会暂时的忘记书里面的细节，但是总会在完全无关的日常家务中突然想起，并因此而呼吸急促。这种恐惧可能会不断地无法克制的反刍。看完真本书，再看姜文导演的《邪不压正》，就更有了历史的厚重和悲壮感。

人们常说千万不能忘记历史。但是如果历史缺少细节和个人化的感受，那么很容易被逐步的解构，并滑入相对主义。所以，要阅读具体的人的感受，感受情绪。

不幸的，出版本书几年后，本书作者在1943年（具体时间不详）被日军杀害。

作者：保罗·布卢姆

译者：青涂

推荐：小编1号

这是很不错的一篇读物，章节长度合适，作者研究3个月到18个月的婴儿对于各种公平性、道德评价的倾向性，非常有意思。这些研究有力的证明了，有些公平性的概念和道德的观念是在婴儿甚至还没有能站立起来的时候就已经开始有清晰的判断了。

或许这对于目前的AI发展也有借鉴意义。如果没有内置的共情、同情、公平性、道德观，我们（硅谷那些人类）有可能培养出来一个我们无法理解、对方也无意理解我们的“怪物”。

本周推荐：《我们为什么要睡觉》

作者：马修·沃克

译者：田盈春

推荐：小编1号

强烈建议所有朋友阅读。睡眠对于我们身体的健康不仅是重要的，而且是奠基性的。就像是金字塔一样，如果睡眠不足，那么运动就有可能从对身体有好处变成有坏处。

近期中文互联网上有传播说午睡一小时然后各种猝死概率增加，这个说法已经被辟谣了，是在特殊的前提下才有的统计学差异。保持7小时左右长睡眠、并且在白天午饭后保持20-30分钟的午睡，对身体有很大的好处。

本书中隔几页就能发现很多神奇的研究发现，虽然可能没什么用，但是很好玩。

好文章： Kavin Gnanapandithan blogged about tracking down and fixing a performance regression in LLVM RISC-V code generation. It walks through the whole process of spotting a regression on Igalia's LNT instance, analysing the problem, and finding and patching the issue.
宋教授！ Fangrui Song wrote about recent performance improvements to the LLD ELF linker. Comparing current main against LLVM 22.1 "Release+Asserts clang --gc-sections link is 1.37x as fast as lld 22.1; Chromium debug with --gdb-index is 1.07x as fast." Read the post for more details, as well as why mold and wild are faster still.

值得收藏： The final meeting working towards the C++26 standard has taken place, see Herb Sutter's trip report for more information.
这个有点步子很大： Jan Korous and Ziqing Luo proposed clang-reforge, an approach for whole-code source code rewriting for security hardening. The RFC outlines the various components, the implementation algorithm, and the motivation. "We propose creating clang-reforge, a whole codebase automatic source code rewriting tool that will change the code to be bounds-safe according to the C++ Safe Buffers definition. [...] We also propose creating bounds-safe alternatives to built-in C++ pointers and fixed size arrays that would work as drop-in replacements. The focus and purpose of these APIs will be enabling automatic large-scale adoption. In other words, we want to create them so it is feasible to write automatic adoption tools that will use them as replacements for built-in types."
感兴趣可以围观和参与： Federico Bruzzone is interested in any data on the individual contribution of LLVM passes to runtime performance.

非常好玩的一本书，非常适合碎片时间阅读。作者作为一个意大利人，在1980年代就开始住在中国了。这本书更像是“外国人在中国看中国”系列，让我们看到原来上世纪的时候，外国人来中国大陆还是有很多限制的，跟现在的大范围免签和全国一遍一遍优化旅游环境形成了鲜明的对照。

对了，老安还是《稍息：1981—1984年的中国》的摄影作者。我以前通过单向书店买过手袋，但是没注意到作者。看来这些相遇也都是命运的安排。

本周推荐：《苏北人在上海》

作者：韩起澜（美国）

译者：卢明华

推荐：小编1号

中国基于地域性其实的各种尴尬笑话和歧视段子伴随着我们从小到大的日常生活，以至于被有意无意的忽略掉。这本书的作者作为一个外国人，尝试从各种文献报道和史料中进行挖掘，尝试还原一个特定的模糊的团体——“苏北人”——这个称谓是如何在过去百年中逐渐的形成亚文化群体。

忽略的时候不觉得有什么深刻，但是当学者开始认真的研究，历史的深度和悲悯心就无法压制的浮现了。清末到民国，自然条件恶劣，旱灾水涝频发，人民太苦了。

本周推荐：《东北游记》

作者：迈克尔·麦尔

译者：何雨珈

推荐：小编1号

这是一个非常有意思的书，作者是一个没过来的中国东北地区的女婿，在一个叫做荒地村的地方每天晃荡，希望有朝一日能够成为作家（还不错，他成功出版了这本书）。

最近几年我看到的很多偏哲学的知识分子分享的时候总是提到“从他者的视角认识自己”，而这本书就恰好是这样。可能我们觉得平淡无奇并且无聊的各种边边角角，作者观察和写出来的时候就还挺有意思的，充满了烟火气和人情味儿，甚至有可能会让仅仅阅读这本书的读者产生了去东北看一看的冲动。

这本书跟流浪地球里面的数字人的概念可能有一些相似。这是一本从我的角度来看很怪的书，我的脑海中不断的出现“恐怖谷效应”来给自己建立思维上的安全围栏。也可能是因为自己看这类的作品比较少的缘故。但是，2023年开始，随着大语言模型（LLM）像是 ChatGPT 和 DeepSeek 出来之后，普通的民众甚至都迅速的适应了一个可以定制情感和态度的算法程序输出，并且已经开始用到了人形机器人身上。

这是一种思维感受的割裂：一方面，理性让我觉得有一种内在的违和与恐惧；另一方面，好像这一切又都迅速的来了，而这个世界上的人在短暂的惊讶之后就迅速的习以为常了。

或许在一两代人的功夫，人类就要面对一个哲学问题：一个没有过肉体存在、纯粹从硅上形成的一个思维体，有可能被认可为有意识和灵魂么？

本周推荐：《代价高昂的健康：美国卫生保健怎么了、怎么办？》

作者：马蒂·马卡里

译者：潘驿炜

推荐：小编1号

美国的医疗费用昂贵和不敢叫救护车，是过去十几年前中文网络世界就流传的段子，而只有直到2025年末，关于美国“斩杀线”说法的流行，才重新严肃的进入到中国的网民的视野。从此再看美剧，就不再是之前的美剧，有了悲天悯人的现实主义意义。

网上的直播和故事化讲述毕竟是带有强烈的情绪和主观性的，来看看美国最为著名的约翰霍普金斯医院的医疗工作者们做的实地研究和系统性的调查，你就会知道，这不是仅仅几十万美国流浪汉的非主流案例，而是整个美国系统性的、不均衡的、在医药集团、医疗集团、保险集团、催收机构、银行信用机构、街头暴力裹挟组合起来的令人窒息的环境。

有几个对于我们会比较猎奇的点，我仅仅列举一二，突然了医疗机构价格公开透明、中央集采的重要意义：

极端案例中，有一个人数大概2.5万人的县，当地的医疗机构起诉过2.3万人次讨要医疗费用，费用是约翰霍普金斯医院费用的5-20倍。这个县的警察、法官、甚至那家医院自己的员工，都悉数被收割过。而隔壁另一个县的医疗机构则完全正常，价格公道，预留5%费用给无法支付医疗费用的人们平账。
美国的直升机救援运送伤员，有的是医院直营，有的是外包给私人机构。私人机构在没有事先询价直接运送的时候，账单可能会比事先询价高10倍以上。询价了1.5万美金，赶上了就是20万美金。笔者记录过一次伤员，同时出现7架直升机降落抢生意的情况。那可是20万美元一趟啊。浙江也有直升机救援，一整年可能都收不到20万美元。
美国有教堂，教堂有时候有健康义诊，但是义诊实际上是在筛选人员做非必要的手术。你能想象“腿部静脉曲张”这种中国人熟悉的小毛病，在美国要多少钱、多少人被非必要的做了手术么？书里会给你惊喜。当笔者作为专业医生告诉当地的牧师的时候，很多牧师都迷茫了。毕竟，如果医生都无法信任，还能相信谁呢。

我始终认为网络上的信息鱼龙混杂，碎片的学习无法得到全貌。还是需要看专业系统的文献资料，才能建立更大的视野。本书，值得翻开。

作者：埃里克·施密特

十年前的书籍，依然值得阅读。作者是编译器领域著名的词法解析工具 lex 的作者，也是 Google 在告诉发展阶段的 CEO，可以说跟两位创始人一起塑造了 Google 和 Alphabet 公司的辉煌。在目前跌中美AI大战中也是具有重要影响力（能决定千亿资金投向）的人物。

书中介绍的公司治理理念、方法、原则、会议技巧、决策流程注意事项，我看了之后都很有感触。2015年之前的谷歌真的是技术人员的向往之地。发现顶尖的人才、围绕顶尖人才创造合适的环境，并且尊重规律。我正在过去十几年的技术团队管理中逐渐积累的经验，与书中的观点遥相呼应，让我看到了很多相同的观点描述。

不过，有一点细节我要提醒各位读者，就是当我们深入去了解这些计算机历史上我们尊敬的领袖和技术导师、从他们的产品、代码、论述中汲取智慧的时候，可能会遗憾地看到，这种因为知识而产生的亲近感是单方面的。影响了硅谷和中国IT科技圈子的众多领袖，包括《从零到一》的作者、谷歌的创始人、美国AI头部企业的创始人，对于中国都公开表达过敌对态度。当我第一次看到相关的英文视频访谈的时候，我的脑海中回想起了马斯克在SpaceX成功之前，被自己所崇拜的英雄、昔日的登月宇航员公开否定时候，脸上那种难以描述的忧伤。即便如此，我依然尊重每一位让我更加智慧的老师，并心怀感激。

作者：道格 · 门德斯

译者：汪婕舒

推荐：小编1号

不要被这本书的名字所误导，这本书其实是一本适合在闲暇的时候翻看的老照片集合，搭配摄影师的一些回忆。书里记录的是1980-2000年代的硅谷的创业者们的故事。那是一个热情澎湃、人才辈出同时又激烈竞争的时代，让我有机会看到乔布斯在NeXT的阶段、以及Apple的牛顿Pad的研发和推广过程中的照片记录。

其中有一个片段的记录是让我最觉得最有戏剧性的：苹果的牛顿PDA始终无法解决手写输入的问题，直到有一天产品负责人在出差的时候，一位紧张的俄罗斯工程师敲开了主管的房门，塞给他一张光盘，然后就走了。这张光盘里正是苹果梦寐以求的手写输入识别程序。

我建议第一次会议定于 12 月 18 日，时间如下：印度时间上午 9:00，中国时间上午 11:30，日本时间下午 12:30，澳大利亚时间下午 2:30，新西兰时间下午 4:30，加州时间晚上 7:30，美国东部时间晚上 10:30（12 月 17 日），英国时间凌晨 3:30（虽然我不指望有人会在那个时间参加！）。

如果您想了解您所在时区的具体时间，可以使用以下便捷的命令，在您的终端中运行即可：

date --date='TZ="Asia/Kolkata" 2025-12-18 09:00'

会议将使用与现有办公时间相同的 BBB 基础设施，我目前不打算更改任何设置，并将与 Carlos 和 Maxim 合作，了解更多关于管理该系统的信息。

如果您有任何议题，请在维基页面设置完成之前告知我或 Maxim。

此致 Ramana

作者：龚琳娜

推荐：小编1号

最近看到龚琳娜是因为鲁豫的博客节目，而顺着节目摸到了这本《做自己，不忐忑》。这本书对于我而言最大的价值就是让我清晰和强烈的进入到了另一个人的生活，看到了另外一种完全不同的生活是什么样子的。作者的文字如此的坦诚，以至于读者甚至会开始担心这种坦诚的自我暴露是否构成了一种需要帮助的表现。而鲁豫和龚琳娜的对谈非常的及时，让我同时感受到了看待同一段人生的多重视角。

确实，已经没有什么好忐忑的了。

作者：刘震云

推荐：小编1号

刘震云的文字，是真顶。我第一次接触到《一句顶一万句》是作者刘震云在一次读书访谈中，三五分钟，寥寥几句话，讲述一个叫灯盏的小女孩的故事，我只是听了一遍之后就莫名的脑海中反复全文背诵，不仅一直能听到刘震云的声音，而且他停顿的时候的表情，也原原本本的浮现。脑子里放不下，一直放不下，就觉得他一定是一个“说得着”的人。

所以拿起来《一句顶一万句》，从第一句，开始默默念起。

社区快速增长： The Clang area team are proposing to grow the team size to 5 in 2026. "We think the Clang area team would benefit from having more folks to take on action items, read RFCs in detail, do more follow-up, and do more to shepherd RFCs along.
