[XGo @xgodev]

Meet spx v4.0.0 🚀 — the open-source 2D engine at the heart of the #XGo (GoPlus) ecosystem.

In v4.0.0, we’ve obsessively aligned spx with Scratch semantics and massively boosted runtime performance:

🎯 Flawless Compatibility:
• Fixed nested broadcasts & wait execution order
• True frame sync for scripts, inputs, & physics
• Accurate motion, sound & drawing (pen pixels now trigger color sensing!)
• Squashed stage UI quirks (no more speech bubble flickers or text overflow)

⚡️ Engine-Level Optimizations:
• Overhauled script scheduling & broadcast overhead (handles massive sprite counts easily)
• Cached collision/color-sensing candidates to slash redundant pixel queries
• Parallelized Web resource loading & minimized memory allocations

The result? We expect this release to seamlessly support >90% of existing Scratch projects right out of the box! 📦✨

支持，什么时候X没有垃圾机器人🤖，什么时候X就可以一统江湖了

[Peter Sellis @petersellis]

I’m joining the team at @X to lead Product.

I am a huge believer in @SpaceX's mission to extend human consciousness to the stars, so it’s time to make shitposting multiplanetary.

X is the best way to find out what’s happening in the world right now and talk about it. The team has been working tirelessly to make X a better place and product for the people who love it, and many have noticed the recent momentum. My goal is to help accelerate that momentum for our community, new users, and businesses globally by continuing to make this product beautiful and useful.

We are twenty years in, but it truly feels like X’s next chapter will be our greatest. I look forward to your ideas and feedback; I’m sure the replies will be measured and magnanimous.

China has a Programmers' Day? No wonder they're thriving. The focus on engineering there is unbelievable. So many of the top companies are run by engineers. That's also why they're getting it with both AI and Omarchy so quickly. The West could do with fewer MBAs at the top!

@mediastorm_en 抽奖抽奖

[Xudong Han @Xudong07452910]

非常推荐读一下 OpenAI FDE 负责人 Colin Jarvis 今天发的这篇工程博客！

他们的 FDE 团队花了几个月给客户做 AI 系统，结果 Codex 变强后，直接删掉了约 90% 的定制代码。

文章用一个半导体客户的真实项目，讲清楚了 FDE 到底在做什么。

工程师直接深入客户团队，跟芯片专家一起设计 Eval、搭建 Harness，把 AI 真正用到芯片验证和调试流程里。

在这个行业，验证约占项目工作量的 70%。前 3–6 个月，几个场景都上了生产：定向测试生成节省约 48% 的时间，几周的调试被压缩到几小时。

但项目上线只是第一步。

随着 Codex 能力提升，团队把原来的定制应用逐步改造成通用 Harness 上的 Skills 和插件。Codex 本身成了交互界面，原来各场景单独写的终端界面和命令行工具全部退役。

扩展到新团队时，基本只需要换上新的连接器和 MCP，再用一个 Skill 生成新的 Eval。第一次部署花了两个月，复制到第二个团队只用了一天。

而当模型能力不够时，FDE 还要把真实业务中的失败案例和能力缺口反馈给 Research。一家电信客户做语音客服，模型一开始在关键 Eval 上只有约 60%，六个月里随着新模型迭代涨到 90% 以上，才达到上线标准。

我很喜欢作者提到的一个目标：让 FDE 不断减少别人对自己的依赖。

我觉得企业 Agent 项目里真正留得下来的，是 Eval、失败案例和沉淀成 Skill 的业务知识；为了补模型短板写的胶水代码，每次模型升级都该重新审一遍，随时准备删。

做企业 AI 落地的建议先收藏。如果你每接一个新客户都还在从头写一套，说明东西还停在定制应用这一层，没沉淀下来。

做浏览器失败

[Arc @arcinternet]

We've decided to sunset Arc on December 22, 2026.

That's not an easy sentence to write. We spent years building Arc and celebrating each and every release along the way: we have so much pride and love for what we made alongside the Arc community.

Our priority is to deliver best-in-class security for our members. Keeping a browser secure takes constant, dedicated work that is only increasing in the age of AI. Dia was built from the ground up to meet today’s security standards, so that's where our engineering and security teams will focus moving forward.

We've worked to make switching to @diabrowser as easy as possible for Arc members. Here's how:

· Your passwords, bookmarks, extensions and history come over to Dia seamlessly.
· Spaces, Folders, and Tab Groups are in Dia and import over with your data intact.
· Dia now surpasses Arc benchmarks in stability, speed, and security.
· The browser features you use in Arc are free in Dia, and the AI is optional.

Thank you for using Arc, for pushing us to make it better, and for building alongside us. The team that made Arc is the same team behind Dia, and some of our most ambitious work is just ahead. We'd love for you to be there with us when it lands.

不错的课程

[Mihail Eric @mihail_eric]

I’m excited to finally announce the newest edition my Stanford course 𝗧𝗵𝗲 𝗠𝗼𝗱𝗲𝗿𝗻 𝗦𝗼𝗳𝘁𝘄𝗮𝗿𝗲 𝗗𝗲𝘃𝗲𝗹𝗼𝗽𝗲𝗿. It has been 9 months in the making.

Last November, with the release of Claude Opus 4.5, coding agents experienced a step function improvement in capability. We all felt it. The LLMs were more powerful, could reason for longer, solve harder tasks.

This year’s iteration of my course reflects the 2026 metamorphosis of software engineering.

My core belief is simple: AI-native developers of the LLM era are going to become the most important members of any software organization. I have designed my course to train this next generation of engineers.

𝗪𝗵𝗮𝘁’𝘀 𝗱𝗶𝗳𝗳𝗲𝗿𝗲𝗻𝘁 𝘁𝗵𝗶𝘀 𝘁𝗶𝗺𝗲 𝗮𝗿𝗼𝘂𝗻𝗱

First, 85% of my Fall 2025 class material is being thrown out. The Fall 2026 syllabus reflects the core capabilities AI-native engineers must have: agent skills, advanced context engineering, MCP portals, agent-ready codebase principles, agentic code review, security, parallelizing background agents, software factories, and more.

Second, I am going to teach my students how to have software taste. Every student will be required to ship pull requests to production-grade, real-world codebases. The course is collaborating with the top open-source AI repos who will offer support and mentorship to students on how to meaningfully contribute to their projects.

This has never been done before in any university course so I am incredibly grateful to our OSS Partners: @browserbase, @HeyGen, @CopilotKit, @semgrep, @OpenHandsDev, @milvusio, @marimo_io, Pi, @crewAIInc, @warpdotdev, @vercel, @cmux, @arizeai, @UnslothAI, and @anyscalecompute.

𝗪𝗵𝗮𝘁’𝘀 𝘀𝘁𝗮𝘆𝗶𝗻𝗴 𝘁𝗵𝗲 𝘀𝗮𝗺𝗲

I’m fortunate to again have AI software engineering leaders and founders as guest speakers to share their learnings from building top coding agent products. Thank you to @leerob from @cursor_ai, @bcherny of @claudeai code, @EnoReyes of @FactoryAI, @silasalberti of @cognition, @0xine of @semgrep, Rajesh Bhatia of @Cloudflare , @amasad of @Replit, and @eladgil.

All resources will be available online. All classes will be available to the public.

9/22 on Stanford campus. See you in class.

[吃白饭的大肥鱼 @big_blue_fish]

Go 是我的主力开发语言，我非常喜欢它。
得益于其极快的编译速度和高性能，我们可以快速迭代后端功能，测试，乃至在 cicd 中快速响应上游漏洞补丁。
Go 原生支持二进制，标准库功能完备，这极大地提高了容器化环境下的部署效率（能够打包出极小的镜像大小，最小化依赖与攻击面）。
对于攻击者而言，Go 标准库+静态网页+自动化漏洞修补流水线的攻击难度是地狱级别的

[Bright | 李小明 | 明说开源 @Bright_OSPO]

呃呃呃呃，我突然发现，低代码那波创业人想做的事情，想做的市场教育，是不是被大模型这一波已经实现了———人人都可以写代码，只需更关注业务本身

当然，比较悲哀的是，大模型也把低代码打趴下了，送上了一锤。
