From #ContainerDays London to Barcelona: big thanks to the #DevOps BCN #Meetup for having me!

I revisited my talk on moving beyond imperative #Docker builds toward #Declarative, #Reproducible and #Secure #OCI #Containers with #Nix:
Hermetic, network-isolated builds, clearer dependency graphs, better layer reuse across images, and a stronger supply-chain story (#SBOM + #SLSA provenance).

On this week's #ITOps Query vodcast, #Microsoft corporate vice president and #Kubernetes project co-founder Brendan Burns envisions a long-term transition in the industry from #declarative cloud-native infrastructure to #intentbasedinfrastructure, facilitated by #AI.

In the short term, the impact of AI on enterprise infrastructure will be strongest in two major areas, according to Burns: reducing toil through automation and improving data summarization with natural language-based infrastructure exploration.

As enterprises adjust to these changes, Burns emphasized that IT leaders should get hands-on, firsthand experience with AI automation tools.

In today’s episode, we’ll cover…

-- The #KAITO #opensource project and #K8s evolution for AI

-- #AIgovernance and control

-- What needs to change about companies' mindsets to best use AI

and more!

#ContainerDays London was great!
Thank you for the interesting talks and inspiring exchange.

I will give my talk "Beyond #Docker Builds: #Declarative, #Reproducible and #Secure #OCI #Containers with #Nix" once again next week, on February 19th at the #DevOps #Meetup in Barcelona.

What a great first day at #ContainerDays London.

Looking forward to see you tomorrow at 09:40 at my talk "Beyond #Docker Builds: #Declarative, #Reproducible and #Secure #OCI #Containers with #Nix".

kiviktnm/decman: Declarative package & configuration manager for Arch Linux.

"Decman is a declarative package & configuration manager for Arch Linux. It allows you to manage installed packages, your dotfiles, enabled systemd units, and run commands automatically. Your system is configured using Python so your configuration can be very adaptive."

Announcing a new #Guix release with version 1.5.0.

https://guix.gnu.org/en/blog/2026/gnu-guix-1.5.0-released/

Guix is a rolling release meaning users receive the latest updates continuously.
This release updates all the installation media when setting up Guix on a new system.

It can be used as a package manager on top of an existing Linux distribution (e.g. #debian, #ubuntu, #suse, #fedora, #archlinux, etc). Or it can be used as a stand-alone #linux distribution installed as #desktop #server or in the #cloud.

Since the previous release Guix has added 12,525 new packages and 29,932 packages have been updated.

- #KDE Plasma and a #declarative configuration service

- There are around 40 new system services to choose from such as Forgejo Runner and RabbitMQ

- Full-source bootstraps of the #Zig and #Mono their compilers are now available

- Other major updates include GCC 15.2.0, Emacs 30.2, Icecat and Librewolf 140, LLVM 21.1.8 and Linux-libre 6.17.12.

- Contributing teams building packages for areas including #openscience, #hpc, #electronics, #python, #astronomy and #rust

Read all about it on the blog and try out Guix now!

Interested in #declarative computing, #linux or #reproducible software? #Guix is going to be at #FOSDEM for lots of goodness on #guile #scheme and the #nix approach to packaging #FreeSoftware - check out the talks various people are giving:

As usual the Declarative and Minimalist computing track will have lots of interesting #lisp #spritely and #nrepl talks!

Heard there is a better way?
