This is called institutionalizable laziness.

[or the golden path if you want to be boring]

Multi-tier security is a rather nice thing to have around your cloud accounts these days. I hear some people get mad when their tools up and smash their fingers on their own ;)

Multi-tier security is an awful thing to have to administer in an account that's mainly IAM Users and Groups and a prayer.

This should help. Quick pair of `verify` and `apply` scripts to manage user provisioning until we're out of here, wrappers around the individual routes and ENV vars so I don't have to keep looking them up

SSO is really nice if you're like /big n stuff/ and still up on the list, but not as much as /generally all the rest of the stuff that makes the access necessary/

At least it's lovely looking

REST isn't dead. But for internal K8s traffic? gRPC wins.

HTTP/1.1 problems:
- Head-of-line blocking
- Connection overhead
- JSON parsing tax

HTTP/2 + gRPC:
- True multiplexing
- ProtoBuf binary (5x smaller)
- 4 streaming patterns

K8s control plane already uses gRPC.

Problémy rychlého používání kódu generovaného umělou inteligencí ve velkých firmách

Ještě nedávno byla nejdražší a nejpomalejší část vývoje samotná tvorba kódu. Dnes se karta obrací. Podle zprávy "The State of Code Abundance 2026: The Gap Between Al Output and Enterprise Control" se firmy dostávají do stavu, který autoři nazývají „code abundance“: AI generuje (nebo významně pomáhá generovat) kód rychleji, než ho organizace stíhají ověřovat, řídit a především připisovat mu odpovědnost.

Your team’s code review process is probably an expensive illusion of quality. Here’s what the evidence says, and what to do instead.

Oh that's just cool right there

Fully automatic Jenkins Configuration as Code that deploys Wanderland.

Wanderland eating its own tail, custom agent & controller images built using Wanderland's core, routes that can be consumed by Rack or Commander. HTTP or CLI, whatever you need at the moment.

Jenkins eats a CasC config that includes a templated job so I can bootstrap everything in one go, completely in configmaps. Add a job to projects.yml, bare minimum to get the repo down and setup external context for Jenkins itself. Jenkins handles ephemeral pods with whatever version of Wanderland you need baked in.

Need a job, push rebuild when you need to, it hot reloads itself. Run your own or share, they're not /that big/ when they're just launchers :)

Wanderland bootstraps from YAML with the routes and tools your project needs inside, maybe a bit of Ruby if one of the packs doesn't cover it. `#call` and helpers.

Neat
