Some nice read on attempts and optimizations for 1m nodes on Kubernetes. Some suggestion are controversial, others are a nice study of Kubernetes components

Eu tenho uns 20 equipamentos (entre tv, ar condicionado, maquina de lavar, 3 notebooks, tv, lampadas). Eles estão conectados via ethernet gigabit mas o mesh deles via wifi funciona muito bem.

Eu jogo bem de boa nele um CoD warzone mas faz tempo que não jogo algo online pra ser sincero

I am very proud of this release.

Among other improvements, we now support evidence chains in PolicySets. This lets AMPEL synthesize verification subjects from attested data.

For example, you can now apply a policy to all the dependencies extracted from an SBOM, the demo below shows how.

Carabiner Systems @carabiner.dev · 20d

We are proud to announce the second beta of 🔴🟡🟢 AMPEL, our software supply chain security policy engine! 🥳

This release includes the final feature patches that were pending before the final release, plus a ton of improvements and bug fixes gathered during the beta.1 test

I've just found that kubernetes.io/docs/referen... is a thing and well, this is very cool!

Declarative API Validation

FEATURE STATE: Kubernetes v1.33 [beta] Kubernetes 1.34 includes optional declarative validation for APIs. When enabled, the Kubernetes API server can use this mechanism rather than the legacy approach...

My mid term dream/plan: moving to a quiet place, no noisy neighbors, no freaking cars, no stupid people vacuuming their houses 6am. Just the noise of birds, the wind and the nature

One of the things I mostly miss(ed) on MacOS was pbcopy/pbpaste commands. Until I realized wayland has wl-copy/wl-paste and well, my life is better again

Wanna test some different GatewayAPI implementations without having to deploy a full Kubernetes cluster? I got you: gist.github.com/rikatz/a5651...

I am using this snippet to deploy some well known GW API implementations on KinD and test some things, it deploys MetalLB as well.

After almost 7 months reading (I am slow) I have finally ended “The 3 body problems” trilogy and can say this is one of the best book series I have ever read.
