What it actually takes to make your app agent-ready (MCP, OAuth, Web Bot Auth, x402 and the rest), a conversation with Expo's Kadi Kraman on shipping React Native at production scale in 2026, a new From Lizard to Wizard date with a Bring-a-Friend deal, and Bun deciding the future is Rust.
New article: How to make your app agent-ready
If you've ever connected Claude to Figma and watched it push frames around, you've already talked to an MCP server. Almost every major app now ships one. This article walks through what it takes to build one for your own app, and the constellation of standards that have shown up around it.
MCP, OAuth, discovery metadata, robots.txt, Content Signals, Web Bot Auth, x402, UCP, ACP. Each one gets a short explanation of what it is, why it exists, and whether your app actually needs it.
By the end you'll have a working mental model for the agent-ready stack and a concrete idea of where to start.

Podcast: Kadi Kraman on React Native at scale
New episode of Señors @ Scale is out. Kadi Kraman is a software developer at Expo with over six years in the React Native ecosystem, having worn every hat from IC to director.
We dug into what makes React Native genuinely competitive with native iOS and Android in 2026, why Expo Go is now just for prototyping, how EAS workflows and fingerprint-based repacks dramatically speed up CI, the real story on OTA updates (and where the legal gray area sits), and what's still missing from the ecosystem.

From Lizard to Wizard — new date, new format, Bring-a-Friend deal
The next session is locked in for Thursday, May 28, 2026 · 5–9 PM CET. Four hours, fully remote.
This round changes shape. It's now a focused Frontend System Design intensive in five parts:
- Frontend System Design — building a WhatsApp-scale chat app the way senior engineers do, with the RADIO interview framework, real-time updates, virtualization, optimistic UI, and state shapes that scale.
- Microfrontends & Module Federation — when they save you, when they don't. Dependency sharing, runtime loading, inter-microfrontend communication, Conway's Law applied to org charts.
- BFF & Server-Driven UI — moving UI decisions to the backend so iOS/Android/web stay in sync without three deploy cycles. Render contracts, the line between SDUI and "downloading code".
- Event-Driven Architecture — components talking through events you can replay, audit, and test in isolation. Event sourcing on the frontend, time-travel debugging, avoiding spaghetti events.
- Frontend Observability — logs vs metrics vs traces. OpenTelemetry end-to-end, distributed tracing across microfrontends, SLOs that don't page on noise, RUM vs synthetic.
Public price is now €299. New this round: a Bring-a-Friend deal — €299 for two seats, so you can bring a colleague or partner along at €149.50 each.

Why Trusted Publishing Can't Save Us by Nodeland — the supply-chain piece doing the rounds this week. Trusted Publishing is being sold as the fix for the next npm token leak, and the argument here is that it shifts the trust boundary instead of removing it.
Chrome may be downloading a 4GB AI model onto your machine via Tom's Guide — Chrome is quietly shipping Gemini Nano weights as part of the new on-device AI APIs. If you've been wondering why your free disk space dropped a few gigs after a recent update, this is probably why.
A Practical Guide to Distributed Tracing by Encore — the clearest write-up of tracing I've read in a while. Spans, context propagation, sampling, what traces actually buy you over logs, and the part most posts skip: how to instrument a real service without ending up with a dashboard nobody opens. Pair this with the observability part of Lizard to Wizard if you've been meaning to actually understand traces.
Bun is being rewritten in Rust via GitHub — the commit is real, the repo is real, the implications are interesting. Zig was always the spicy choice, and the team is now openly migrating the runtime to Rust.
Security Through Obscurity Is Not Bad by Mo Beigi — the contrarian take on a phrase every security person reflexively dismisses. The argument is that obscurity is fine as defense-in-depth, the problem is when it's your only defense.
Where the Goblins Came From by OpenAI — a surprisingly fun behind-the-scenes piece on the data, taste decisions, and iteration loops behind a single visual style in their image models. If you've been generating assets with these models and wondering why some prompts hit and others don't, this gives you a window into the choices upstream.
How AI Remembers and Forgets, Part 2 by Nadia Makarevich (DeveloperWay) — the follow-up to her first piece on context windows and memory. Part 2 goes into compaction, summarization, and the actual mechanics of how long-running agents avoid amnesia. If you're building anything on top of an LLM that has to hold a thread across more than one turn, read both parts.
Accessibility in React: Common Mistakes and How to Fix Them by Certificates.dev — a tight checklist piece on the a11y mistakes React developers ship without realizing. Focus traps, ARIA roles applied wrong, divs masquerading as buttons, the works. Save it for the next code review where someone PRs a custom dropdown.
