try this next “use /create-formal-verification-skill to model these state machines, one skill per subsystem. and use /statechart to visualize my most important user flows” both skills are in pstack github.com/cursor/plugins/tr…
good prompt "find all of the implicit state machines in my app"

And specifically, does understanding React still matter? I'd say yes, more than ever
🧠 If AI writes the code, do software fundamentals still matter? @mattpocockuk makes the case in his talk recording: gitnation.com/contents/why-s…

Memory is what allows Claude to learn from experience. In a new Engineering Blog post, we share how “dreaming” helps Claude organize what it’s learned, correct its mistakes, and find what it needs more easily the next time. anthropic.com/research/compo…

hot take: you don't need a software factory, and i don't love the term. it's just marketing all you need is good software engineering and investing your tokens in the right places. the more deterministic the better (and token efficient)
all the companies selling you a software factory produce a shockingly tiny amount of software

We rebuilt our mobile apps in Swift and Kotlin with agents. To keep pace and hold our quality bar, we built Reflex: an agentic-first architecture that lets agents build and verify app behavior across iOS and Android without needing devices or simulators. Here's how it works, piece by piece: shopify.engineering/reflex

The web rewrite is working. On a slow connection, the old X web took more than 22 seconds to show the first post on a profile. The new X web does it in 2.7 seconds. Here's how we did it, and how we're rolling it out one country at a time. blog.x.com/en/engineering/re…

We built Pando, a new Git backend for our monorepo, to handle more pushes and fetches without changing how our engineers and agents use Git. Pando cut push latency by ~80% and now serves nearly a petabyte of Git data a day. We can grow Git capacity alongside agent usage.

the creativity and pace of the community has been astounding. my favourite so far is `neorex`, a plugin for neovim which gives it Rex-native splits and floating windows. github.com/alexrlocke/neorex

最近深入支持了一些顶流 Agentic Web 工程,也是顺利都迁移到了 Rsbuild 2.x: - Chatgpt (Rsbuild + React Router) - Copilot (Rsbuild+ Tanstack Start) - 豆包 (Rsbuild + Modern.js) 一些小发现: - 前端没全死,复杂业务仍有挑战 - 在八位数代码量的大仓里,现有工具都不够快 - 多 agent 并行开发,内存成为新瓶颈 - 普遍使用 SSR - 从零写一个超大型工程的时间被压缩至一两年 - 构建工具需要更好的按需编译和持久化缓存支持更大的研发规模 - 未来可能有分布式编译或全新的 bundler 架构来突破上限

here’s a short grok bot guide on how i create high quality bots and manage my team. ask @bot to read this post and help you improve your team! • add dr eggbot to your team! he’s my bot designer that i use to create bots • you don’t need a lot of bots. a few good bots can be more useful and easier to manage than a large team • tell your bots to create skills for itself as you give it instructions on how to do tasks. this lets them do them more consistently even over long conversations. you can even ask it to create a private github repo for you to store all your skills if you want them preserved independently • add connectors, use the vault, and give access to all the tools you use to do your work. you can also ask your bot to setup its own email and it can sign up for its own accounts for better separation • thinking about all the work you do by hand, or steps in your workflows where you have to copy and paste information back to your bot. ask your bot how it can do that for you instead! • imagine you hired an intern, how would you onboard them and help them do the work correctly and efficiently? introduce yourself to your bot and describe the work you do, then ask it how it can help you automate it and my favorite tip: use voice mode or the transcription option! it’s a good way to just brain dump a lot of information. then, at the end, tell your bot to “restate this in your own words” so you can confirm it understood you x.ai/bot/_jOdbfkB16zxu7MRcmR…

I like it!
A quick demo of floating panes in Rex, some of their features, and how I use them in my daily workflow. I think our implementation of floating panes looks great and feels great and I think you'll love it! These are also all scriptable and API driven, too, of course!

Did somebody say "reducers"? :)
Yes! useReducer (and state machines, when needed) have ALWAYS been the better default. Devs just avoided them because upfront modeling felt like too much work. Agents don't care. They're not lazy, and explicit logic keeps them from doing dumb things.

Are we ready to admit React hooks were a mistake or do we need more time?

the /statechart skill in pstack v0.15.36 is now stable and ready for use! it's best combined with /create-formal-verification-skill to abstractly model state machines and distributed systems to find bugs. the skill contains a mini tlc compiler that parses, lowers to a small IR, and has a backend that outputs mmd syntax. if you want you can also ask your agent to create charts in whatever style you like, the skills tells it to use pele.run/ which is very themeable so you can make blueprints, hand drawn encyclopedia illustrations or whatever you like here's a chart of the /statechart skill and 2 real bugs i just found. try it out and let me know what you think!
