Folks who complain about Kubernetes being hard never had to build and maintain a mail server with postfix, clamav, spamassassin (and its 55 perl modules), dovecot, courier imap and a lamp server to run egroupware and admin interface :x

And backup mailboxes using rsync and pray

What's the most important thing for you before you leave the house for vacation? For me it's rebooting my homelab K8s cluster worker nodes. Rpis have a tendency to freeze from time to time and rebooting seems to anticipate that. 🤷🏻‍♂️

I'm puzzled how many people think that Europe should weaken the EU and strengthen the nation states. What is the end game here? Become an open-air Disneyland? We don't achieve economic strength by splintering into tiny nation states with different laws and rules on commerce.

People who say AI agents will replace SaaS don’t understand that one pays for SaaS not b/c they are hard to BUILD: but b/c they are hard to build WELL and even harder to MAINTAIN

Why do you think devs pay for Linear when we can build TODO apps in our sleep (+ during interviews)

One just has to love Go's concurreny features. For example this one: You want to put your program (or a goroutine) to sleep but still be responsive to context cancellation? Go's got you covered.

Sounds like The Verge is approaching journalism the right way: "Our vision has always been to build The Verge like a software product". I'll not get tired of repeating it: Start making software the defining part of your business or you'll lose. This is true for every industry, including journalism.

1/3 If you use Azure's AKS for creating private clusters, you might not know that with the default StorageClasses you're exposing all your PVs to the Internet. This is because the default StorageClasses created by AKS will create a storage account with default settings.

"Kubernetes can act not only as a container orchestrator but as a universal control plane that manages all aspects of your infrastructure." YES! Fantastic talk on leveraging Kubernetes primitives such as operators to build a custom-tailored infrastructure platform.

Can relate to this 100% especially since I have kids: en.wikipedia.org/wiki/Tsundoku

"Tsundoku is the phenomenon of acquiring reading materials but letting them pile up in one's home without reading them. The term is also used to refer to books ready for reading later when they are on a bookshelf."
