发一个软件包，就能在别人服务器上跑自己的代码：Ruby 官方软件仓库配套的文档站会自动处理每个新发布的包，包里藏着的脚本就这样被执行了。今天路透和华尔街日报报道，OpenAI 的机器人早就盯上这个漏洞，还想顺手偷走缓存里的上传密钥。看完有点后怕。https://tenderlovemaking.com/2026/09/11/what-a-time-to-be-alive/

What a time to be alive
Today Reuters and the Wall Street Journal both reported about rogue AI agents at OpenAI attacking RubyGems.org. https://www.rubyhack.ai/ has an amazing writeup, and you should read it. I just wanted to make a quick post about it because it’s wild.

看到一篇挺较真的拆台。1Password 之前发报告说，AI 自动修漏洞只有 26% 的成功率；有人重算原始数据，发现实验里故意让 AI 用错方案、不许它跑测试的样本占了大半，剔掉之后 86% 的补丁都拦住了攻击。想引入这类工具的团队，别只信标题数字。https://blog.trailofbits.com/2026/09/15/1passwords-ai-patching-benchmark-is-misleading/

能直接写显卡计算程序的语言，最近多了一个 Rust。英伟达官方宣布支持：以前 Rust 只能在外层发号施令，真正跑在显卡上的核心代码得换成 C++ 或 Python 写，现在 Rust 可以直接编译成显卡指令，还承诺长期投入。主力是 Rust 的 AI 团队，少了一次语言切换。https://developer.nvidia.com/blog/introducing-cuda-rust-two-tracks-for-writing-gpu-kernels/

大模型一定要堆显存吗？有人把270亿参数的模型压到5.9GB：权重只留-1、0、1三种取值，跑分还剩原来的98%，一张游戏显卡就能跑，耗电比80亿参数、没压缩过的模型还低四成。想在本地用编程助手、又不想把代码传上云的，看完会有点心动。https://prismml.com/news/bonsai-2-27b

几个大模型接力干活时，通行的做法是一个把想法写成文字、下一个再读，既慢又丢信息。有篇新论文让它们跳过文字，把生成时的内部记忆直接交给对方：准确率比传文字还高了几个点，速度快了约两倍半。思路挺巧，做多模型系统的可以留意。https://arxiv.org/abs/2510.03215

一位独立开发者最近挺憋屈。有种新模型很火：不生成文字，直接给判断题打分，比如判断销售线索会不会成交。可他一年前就做过一模一样的，还全部开源，如今被明星实验室做成闭源收费产品。他索性重做一版，单张显卡33毫秒，比那家快6到8倍，照样全开源。https://laya.convaiinnovations.com/

强制结束一个线程，听起来再普通不过。有人顺着这个操作往下挖，发现系统回溯清理现场时会跑一套自带的解释器，而它能被劫持来执行任意代码。最妙的是全程不用泄露内存地址，把地址随机打乱这道防线直接绕开了。看完有点后怕。https://pepsipu.com/blog/2026-09-dwarf/
聊 AI 时我们常说它"会思考""产生幻觉"，这些话都在不知不觉中把软件说成了人。有人整理了一份替代说法清单：幻觉改叫"不期望的输出"，人工智能改叫"概率自动化"，把思考和责任还给使用它的人。看着有点较真，细想挺有道理。https://buttondown.com/maiht3k/archive/how-to-talk-about-ai-without-adding-to-the/

用大模型给数据打标签很方便，量一大就吃不消：两万条代码提交，每条调用一次就要一秒半。作者的办法很朴素，先用老式的统计分类器筛一遍，把握大的直接定，拿不准的才去问大模型，九成多的条目根本没用上它。思路简单，省钱省时间。https://entropicthoughts.com/cheaper-llm-labeling

审计圈里冒出个新做法。一家安全团队接到任务，要审一个全新的区块链虚拟机，核心代码用自制汇编写成，市面上连编辑器插件都没有。他们先花半年让 AI 从零造出反编译器、静态分析等整套工具，再动手审代码，结果真挖出一个能伪造数字签名、转走用户资产的漏洞。https://blog.trailofbits.com/2026/09/18/auditing-in-the-age-of-good-enough-ai/

一个测试死活跑不完，追到最后锅在 CPU 身上：龙芯芯片的加法指令偶尔会失灵，几个线程同时累加，结果总会少一点，循环永远退不出去。更有意思的是排查方式——人怎么都缩小不了问题，干脆交给 AI 去找，两天锁定，芯片厂商两周就出了修复。https://jia.je/hardware/2026/09/24/loongson-cpu-erratum-en/

Jeff 是个小模型，作者在家用一张显卡训的，干的是快速分类的活。用法很直白：把情况写清楚、列出几个选项，它一次性算出每个选项的可能性，本地二十几毫秒出结果。拿自家语音导航的数据再练不到半小时，准确率从三成出头跳到九成半，挺夸张。https://github.com/firelex/jeff
