TypeScript, C# and Turbo Pascal with Anders Hejlsberg（Pragmatic Engineer）
中文摘要：TypeScript、C# 与 Turbo Pascal 的缔造者 Anders Hejlsberg 在 Pragmatic Engineer 播客中回顾其编程语言设计生涯，并分享对 AI 如何改变软件工程未来的见解。他指出 AI 在特定语言上的表现取决于训练数据量，TypeScript 和 Python 表现优异正因互联网上有大量样本；但 AI 目前在编写编译器方面仍有局限，难以把握类型、符号、绑定与解析之间的全局关系。Hejlsberg 预测未来开发者将更像项目经理，管理大量生成代码的 Agent，而代码审查可能成为新的核心技艺。
English Summary: Anders Hejlsberg, creator of TypeScript, C#, and Turbo Pascal, reflected on his language design career and shared insights on AI's impact on software engineering in the Pragmatic Engineer podcast. He noted AI performance in specific languages depends on training data volume—TypeScript and Python excel due to abundant online samples—while AI remains limited in writing compilers, struggling to see the big picture across types, symbols, binding, and parsing.

Quoting Boris Mann（Simon Willison）
中文摘要：开发者 Boris Mann 在 Simon Willison 博客的引用中指出，"11 个 AI Agent" 这一表述作为短语毫无意义，类似于说"我有 11 个电子表格"或"我有 11 个浏览器标签页"来完成工作。该观点引发对当前 AI Agent 概念泛化与营销话术的反思，强调 Agent 数量本身并不能说明工作流的实际价值或复杂性，呼吁行业关注 Agent 的实际能力与协作质量而非简单计数。
English Summary: Developer Boris Mann, quoted on Simon Willison's blog, argues that "11 AI agents" is meaningless as a phrase—akin to saying "I have 11 spreadsheets" or "I have 11 browser tabs" to describe one's work. This observation sparks reflection on the current overgeneralization and marketing hype around AI agents, emphasizing that agent count alone doesn't indicate actual workflow value or complexity, and calling for the industry to focus on agent capabilities and collaboration quality rather than simple enumeration.

Building a safe, effective sandbox to enable Codex on Windows（OpenAI News）
中文摘要：OpenAI 发布技术博客详细阐述如何在 Windows 平台为 Codex 构建安全沙箱。由于 Windows 缺乏类似 macOS Seatbelt 或 Linux seccomp 的原生隔离机制，团队评估了 AppContainer、Windows Sandbox 和 MIC 等方案后均放弃，最终自主设计了一套基于合成 SID（sandbox-write）和写限制令牌（write-restricted token）的权限系统，实现无需管理员权限即可限制文件写入范围。网络隔离方面，早期原型仅通过环境变量和 PATH 劫持进行软性阻断，但存在被绕过的风险；最终版本引入防火墙规则，创建 CodexSandboxOffline/Online 两个专用本地用户，实现强制的网络访问控制。整个架构包含 codex.exe、codex-windows-sandbox-setup.exe（提权设置）和 codex-command-runner.exe（命令执行器）三个核心组件，在安全性与开发者工作流兼容性之间取得平衡。
English Summary: OpenAI's engineering blog details building a secure sandbox for Codex on Windows. Without native OS isolation primitives like macOS Seatbelt or Linux seccomp, the team evaluated and rejected AppContainer, Windows Sandbox, and MIC. They designed a custom solution using synthetic SIDs (sandbox-write) and write-restricted tokens to limit filesystem writes without requiring admin privileges. For network isolation, the initial prototype used environment variable hijacking but was advisory-only; the final implementation uses Windows Firewall rules applied to dedicated local users (CodexSandboxOffline/Online). The architecture comprises three binaries: codex.exe, an elevated setup utility, and a command runner, balancing security with practical developer workflows.

CSP Allow-list Experiment（Simon Willison）
中文摘要：Simon Willison 发布实验工具 CSP Allow-list，展示如何在受内容安全策略（CSP）保护的沙箱 iframe 中加载应用，并通过自定义 fetch() 拦截 CSP 违规错误，将信息传递至父窗口，从而提示用户将特定域名加入白名单并刷新页面。该实验基于此前关于测试 CSP iframe 逃逸的研究，使用 GPT-5.5（xhigh 模式）在 Codex 桌面应用中开发完成。工具演示了一种在严格 CSP 环境下实现动态域名授权的技术路径，对需要在受限环境中运行第三方代码的开发者具有参考价值。
English Summary: Simon Willison released the CSP Allow-list Experiment, demonstrating how to load an app inside a CSP-protected sandboxed iframe with a custom fetch() that intercepts CSP errors and passes them to the parent window. This allows prompting users to add domains to an allow-list and refresh. Built with GPT-5.5 xhigh in the Codex desktop app, the tool showcases a technical approach to dynamic domain authorization under strict CSP constraints, relevant for developers running third-party code in restricted environments.

[AINews] The End of Finetuning（Latent Space）
中文摘要：Latent Space 发布评论文章探讨微调（finetuning）的终结趋势。文章指出 OpenAI 近期弃用其微调 API 是这一趋势的最新标志——尽管 OpenAI 曾是大型实验室中微调支持的代表，并长期宣传"以 o1 的性能获得 4o 的价格"这一理念。作者认为，即使没有极端的 GPU 供应紧张，AI 工程行业的主流趋势也在向提示工程（prompt engineering）和上下文学习转移，Fast.ai 的 Jeremy Howard 早在 2023 年就已预言这一点。不过文章也强调，这并不意味着微调完全消失：Cursor、Cognition 等顶级应用公司反而增加了开放模型的 RLFT（强化学习微调）使用，开源模型微调在定制 ASIC 推理方案中也可能扮演关键角色。
English Summary: Latent Space published an op-ed on the declining role of finetuning in AI engineering. OpenAI's recent deprecation of its finetuning APIs signals a broader shift, despite years of promoting "o1 performance at 4o prices." The author argues the industry was already trending toward prompt engineering and in-context learning, as Jeremy Howard predicted in 2023. However, the "end" of finetuning for most doesn't mean its total disappearance: top-tier companies like Cursor and Cognition have increased RLFT usage on open models, and open-model finetuning may remain central to custom ASIC inference strategies.

How NVIDIA engineers and researchers build with Codex（OpenAI News）
中文摘要：NVIDIA 工程团队分享使用 Codex（基于 GPT-5.5）的实践案例。Codex 已成为 NVIDIA 工程师处理复杂工程任务的首选工具，帮助内部平台从 MVP 演进为生产级系统，并在数小时内构建出内部播客录制应用（含音视频测试），而传统采购流程可能需要数周。研究团队则利用 Codex 实现端到端机器学习研究流程的自动化：从文献综述、假设生成到实验脚本编写和远程集群执行，研究效率提升约 10 倍。研究人员还使用 Codex 进行代码迁移，将 Python 代码库重写为 Rust 以获得高达 20 倍的性能提升。目前 NVIDIA 已有约 4 万名员工获得 Codex 访问权限。
English Summary: NVIDIA engineers shared how they use Codex (powered by GPT-5.5) in production. Codex has become the default tool for complex engineering tasks, helping evolve internal platforms from MVP to production-ready systems and building an internal podcast recording app with audio/video testing in hours instead of weeks. Research teams use Codex to automate end-to-end ML workflows—from literature review and hypothesis generation to experiment scripting and remote execution—achieving roughly 10x speed improvements. Engineers also use it for machine translation, rewriting Python codebases to Rust for up to 20x efficiency gains. Approximately 40,000 NVIDIANs currently have access to Codex.
