2026 in review: when a surprising moment happen (layoff) but then you are hired to do what you enjoy as your day job (instead of spending weekends on it). And I am genuinely happy with it.

Sometimes the storm really comes before the calm waters :)

Meu mês do Linkedin resumido em 3 linhas:
* especialistas em ingress-nginx
* migro seu Minio e trago a pessoa amada em 7 dias
* o que podemos aprender com o marketing da Havaianas e o excesso de paranóia na interpretação de propagandas

É isso, que venha 2026 pq esse ano já deu….

Here is something very stupid I am doing, because you probably want to know what is already supported from Ingress to Gateway API: www.rkatz.xyz/ingress-ngin...

Have fun

Kubecon EU 2026 schedule is out, and I got a very fun talk accepted: sched.co/2CVyZ

Expect me doing a Gateway API implementation using kgateway as control plane, and dataplane being an Apache HTTP Server running on FreeBSD and using BGP to know how to route to the Pods (maybe not that much!) :x

Protip: never say “oh apparently they decided to use a proxy written in Rust due to performance improvements” on a room filled with Kernel contributors.

Spotted on Reddit: github.com/kiki-ki/go-qo

Because I never remember jq query format as well!
GitHub - kiki-ki/go-qo: qo is an interactive minimalist TUI to query JSON, CSV, and TSV using SQL.

Today I was accused of being very patient, and clearly the person who said that doesn’t know what he’s talking about :P

How old were you when you discovered that gmail ignores “.”, so sending an email to user.last@gmail.com == userlast@gmail.com == userla.st@gmail.com

My experience contributing to Istio so far has been great. The CI is extremely fast, provides a lot of useful information (even the "generate check" command provides me a "git patch" command to fix directly things).

Seriously, very cool experience
