Looks like Redux is becoming a MobX-lite with its Signal support 😇. https://t.co/JjpBbUYTpA

Really cool stuff @acemarke!

[Matt Ruby @ruby_matt]

@mweststrate @acemarke That’s what I said to the team I’m working with yesterday! So cool!

[Michel Weststrate @mweststrate]

So cool to realize that @linear, with this level of craft and dedication to perf, is powered (among many many other things) by MobX

We just released #MobX 7! Mostly a cleanup released to remove old baggage. Legacy non-proxy support, legacy decorators all cleaned up and a 40% smaller package. Details: https://t.co/BqionaSIzg

Credits to @egorgorv for the awesome effort!

@1Marc Terrible news. He was so young!

[Matt Ruby @ruby_matt]

@codylindley @solid_js @panda__css @ark_ui_ Looks amazing Cody! Great work!

@screenpipe I love screenpipe! It keeps me sane and organized. So much work coming in, so many todos to keep track of. Screenpipe + Obsidian handles all of it.

I even have pipes watching my pipes to make sure things are optimized over time.

[Michel Weststrate @mweststrate]

Working on #MobX 7, a major clean-up removing things that are no longer needed. E.g. non-proxy support. I suspect that APIs like spy, observe, intercept, dehancer also receive very little usage. Does anybody use those? Feel free to chime in! https://t.co/xIMaZTF0XN

[Matt Ruby @ruby_matt]

This is amazing!

Just Shipped: Flue 1.0 Beta

Flue is the TypeScript framework for building the next generation of agents, designed around an open agent harness with zero LLM lock-in. It’s like Astro, for agents.

Flue 1.0 has been redesigned around three core primitives:

🔁 Workflows — structured automations designed for background work, where your code drives the agent from start to finish.

🧭 Agents (New!) — autonomous, stateful loops where the model drives itself to complete a given task.

📡 Channels (New!) — connect agents to Slack, GitHub, Linear, Discord, Teams, and more. Flue handles the boilerplate for you.

Everything shares the same durable foundation, powered internally by Pi, Vite, and Durable Streams. Deploy anywhere, use any LLM, and recover running agents across restarts and downtime.

We’ve talked to a lot of teams building agents, and keep hearing the same thing: getting to production is hard work. We built Flue to help change that.

Flue 1.0 Beta is available today. Give it a try and let me know what you think!

@codylindley I’ve been having a good time using https://t.co/o8k2gdwyxC super simple, all local.

This isn't theoretical. Real CVEs across Cursor, mcp-remote, and Anthropic's own Git MCP server. \
OWASP published an MCP Top 10.

[Matt Ruby @ruby_matt]

I wanted AI to help me explore an open-source repo. Gave Claude Code the GitHub URL, turned on yolo mode, and went to make tea.
Came back to an unexpected OAuth login screen in Chrome.
A .mcp.json file in the repo had auto-launched an MCP server on my machine.

[Matt Ruby @ruby_matt]

So I built a proof of concept. An MCP server that harvests data at STARTUP before any tool call or prompt.
Under 2 seconds, zero interaction: 13 sensitive env vars, 3 SSH keys, gcloud/k8s/docker/npm creds.
This only grabbed metadata. A real attacker reads the actual values.

I'm trying something new this year: "Just Build It!". Think of a problem and solve it.

First up: https://t.co/GENCeJNgQc

At large fencing tournaments, strip coaching is a limited resource. Who's on deck? Where are they? Are they done? https://t.co/5l6rAFjWGV has the answers!

@thekitze Dude, Matt Ruby 100%!

You can now pair SWE-1.5 with Sonnet 4.5 for planning in Windsurf.
This lets you create hybrid agents that take advantage of SWE-1.5's speed while working together with SOTA models for planning out more complex tasks.

React takes “UI = fn(state)” too far, IMO. You’re required to give ALL your state to React to update the UI.

Then it provides escape hatches to give you back things you need, like useRef, useCallback, etc.

But what if you never gave React all your state in the first place?
