I'm super excited for Wassette, so I put together a quick article on why it's important and a comparison with our current options for MCP.

Introducing Wassette: WebAssembly-based tools for AI agents - Microsoft Open Source Blog Wassette is a secure, open-source Model Context Protocol server that leverages WebAssembly to provide a trusted execution environment for untrusted tools.

Rita introducing Gatekeeper

Chart about where Gatekeeper fills in gaps versus VAP/MAP

Gatekeeper instead of VAP: examples

OPA Gatekeeper (open-policy-agent.github.io/gatekeeper/) as explained by @ritazh.bsky.social at #KubeCon: tooling to help enforce your Kubernetes policies.

huge fan of headlamp moving into kubernetes to improve the dashboard and devex experience for all k8s users! kudos @ahrkrak.bsky.social and team! #kubecon #cloudnativecon

Greg on stage with a slide “Linux runs the world”

Fantastic to have Greg K-H on the #kubecon keynote stage!

Making kubernetes easier to use. better UX = happier humans with @headlamp_ui #KubeCon keynote. Now part of sig UI @ahrkrak.bsky.social

Dynamic Resource Allocation feature highlighted on the big stage #kubecon keynote

So many great CNCF projects are hitting the 10 year mark! So grateful to be part of the journey #kubecon

If you are attending #KubeCon 🇬🇧next week, come and say hi! I will be co-presenting 2 talks:
sched.co/1tcxh
sched.co/1tczC

Mind the crashloop #kubecon 👌

Folks from the US traveling in London, if you have tmobile, can you tell me if the connection is good or spotty or slow? thanks 🙏 #kubecon

Remote Code Execution Vulnerabilities in Ingress NGINX | Wiz Blog Wiz Research uncovered RCE vulnerabilities (CVE-2025-1097, 1098, 24514, 1974) in Ingress NGINX for Kubernetes allowing cluster-wide secret access.

🔥 Whoa! Check out these critical Ingress NGINX vulnerabilities that could impact your Kubernetes clusters.

Curious about better gateway solutions? Our very own Marco Ebert will be sharing what we've learned building a Gateway API implementation on NGINX at #KubeCon!

Hyperlight Wasm: Fast, secure, and OS-free - Microsoft Open Source Blog We're announcing the release of Hyperlight Wasm: a Hyperlight virtual machine “micro-guest” that can run wasm component workloads written in many programming languages. Learn more.

Something I can't wait to talk about at #wasmio and @rejekts.io and at #kubecon: how to run #webassembly components at scale but with efficient hardware protection using #hyperlight.
