宋教授笔耕不缀: Fangrui Song wrote about LLD changes in the upcoming LLVM 22 release.
社区治理持续改进: LLVM Community Area Team Elections are open for voting until February 9th. Thank you to everyone who put themselves forward.
北京 LLVM Meetup 开始恢复: A Beijing LLVM x RISC-V meetup will take place in Beijing on February 6th.
好事儿: Petr Hosek suggests adding a new PR label that can be applied to a PR that was landed unapproved, to make someone reviewed it.
郑同学! Yingwei Zheng would like to upstream an undefined behaviour aware LLVM IR interpreter, which amongst other things would aid in reducing miscompilation reproducers. So far there is strong support, alongside questions of what happens to the existing ExecutionEngine interpreter.
“情绪引擎”是个啥: Support (CPU definitions, a hardware errata fix, and exposing the correct set of supported instructions) was added for the Mips R5900 CPU used for the 'Emotion Engine' processor in the PlayStation 2. f4b593a.

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?
