200 milliseconds. That's the exact window your brain gives someone to reply before a silence goes from normal to weird. It's not an arbitrary UX rule, it's literally just biology.
I wrote down some thoughts on what that actually looks like under the hood 👇

Baked an on-device visual narrator by running Qwen3.5-0.8B on WebGPU 🤓
It can describe, analyze, or extract text from any pasted or uploaded image, all without your data ever leaving your machine.

Taalas HC1 implements model weights directly into silicon logic, bypassing the instruction-fetch overhead of traditional GPUs. Hitting 17k tokens per second!
"Mask-ROM" layers makes the chip tied to a particular model version with no flexibility for any changes after tapeout.

I baked Samvada a fully Indic-stack AI Counselor that uses Sarvam's models for almost realtime inference 🤓
Audio → VAD -> STT (saarika:v2.5) → Text → LLM (sarvam-m) → Text → TTS (bulbul:v2) → Audio
P.S: Will try to host, but need to get the compliance right.

Built ucpify because every commerce backend starts the same way: products, checkout, payments, auth.
Now it's one JSON file: → npx ucpify serve config.json → 13 endpoints, Stripe + PayPal, OAuth 2.0 → Node.js and Python
That's it. No framework. Just a config.

Built webmcp-bridge to map remote MCP tools into WebMCP in the browser.
Connect MCP server -> discover tools -> register with navigator.modelContext.provideContext() -> invoke from browser AI (Prompt API) surfaces.

As developers, we used to wait for standards. Now we just read the README.
My latest post explores the "Cambrian Explosion" of AI Agent protocols (MCP, UCP, UTCP, A2A, ACP) and asks a hard question.

agentu now supports shorthand formats: user/repo, user/repo@branch.

The hardest part? Code blocks broken by 5+ migrations

My 9-year-old said it should be easy to turn $500 into $5,000 with stocks. I told him to prove it, so I built an app with real market data and a trading
dashboard. If he pulls it off, he will get $500 for real.

Baked a remote MCP server for TC39 proposals 🤓
Use `tc39-mcp.deno.dev/mcp` to connect to the server.
P.S: This is not a official remote MCP server from TC39 (yet) ;)
Demo is via mcphost.link

The idea:
1. Your keys stay in one vault
2. Apps request scoped access
3. You approve and they get a token (not your master key)
4. Revoke any app instantly
Would you use something like this?
What am I missing?
I have API keys for OpenAI, Anthropic, Google, Groq, Samabnova and more.
Many AI tools ask me to copy-paste them directly. Keys end up scattered. No visibility. No control.
Here's my proposal: OKAP (Open Key Access Protocol)

Introducing mcphost.link a web-based MCP host to connect with multiple MCP servers in one clean chat UI! 🤓
• Multi-server
• OAuth2 / Bearer
• Persistent sessions
• Full MCP tools/resources
• LLM support
Demo below 👇
Built a sample implementation with vanilla Web Components.

Your AI agent calls a tool, gets back a full interactive UI. Dashboard, form, chart - whatever you need.
How it works:
- Tool returns text/html+mcp resource
- Client renders in iframe with CSP
- UI talks back via JSON-RPC 2.0 postMessage
- Fully sandboxed, secure by default
Rendering UI with MCP will get easier sooner
SEP-1865 MCP Apps Extension, even though in draft currently, will change how AI agents deliver interactive experiences.
The idea: MCP tools return HTML/CSS/JS directly. The client renders it in a sandboxed iframe. That's it.
Hands down, @AnthropicAI's Opus 4.5 is the best coding model I’ve ever used!
I gave Opus a very tough MCP UI challenge and even said, “I bet 1000 BTC you can’t fix it.”
Not only did it fix the bug, it didn’t even keep the 1000 BTC! 🤓

Nov 25, 2024; Anthropic released MCP, I vividly remember running the Brave search local MCP on my machine…🤓
From the early “local MCP experiments” to today’s more mature ecosystem with remote MCPs, secure tool calling, and increasingly capable code-execution workflows the pace has been wild!
Got bored with the in-flight entertainment, so I opened DevTools and ran a performance audit on the Alaska Airlines’s web app 🤓
I don't know devs from their team, but happy to pair with them if needed.

pip install piragi

That's it.
Built-in vector store, embeddings, citations, and auto-updates. Free & local by default.
