Some highlights from our work on kubernetes-sigs/headlamp last year.

https://kubernetes.io/blog/2026/01/22/headlamp-in-2025-project-highlights/

It’s been a pleasure working with different folks this year and learning about all sorts of different projects. But looking forward to this year much more!

My main work goal for this year is to **help people reduce energy use**. Let’s see how it goes🤞

One feature added to kubernetes-sigs/headlamp recently is Projects. Organise resources across multiple namespaces, clusters and clouds. What some teams consider an "application" or "project" are spread out, and this lets us provide an app specific view for developers and teams. If a team uses several micro services this is useful to see all the related resources together even if they are in different namespaces, clusters or clouds.

#Kubernetes #Headlamp 0.38.0 adds a Custom local port dialog for Port Forwarding, Improves plugin handling with shipped/user/dev types and priority loading, Supports priorityClassName in the Helm chart, fixes Username display when Headlamp is deployed behind OAuth2Proxy and fixes a Port clash issue the Desktop Headlamp had. In the documentation there's new Learn Projects docs and Learn Local Clusters docs.

Been noticing an interesting trend with some of the optimisations we've been doing to the #Headlamp #Kubernetes UI. They mean a lot more to slower laptops but in relative terms of X times faster improvements they are greater on quicker laptops.

For example, one change was 19 seconds faster but in relative terms that was 8,3x times faster on the 2025 CPU. But only 2.3x faster on the 2019 CPU (but almost a minute faster).

The faster IO, memory and CPU make optimisations multiplicative.

New #Kubernetes UI #Headlamp 0.35.0 is out 🎉 With grouped CRs in the sidebar, a projects view, an optional #k8s caching feature, fixes for Mac app first start, much faster development experience, Gateway API resources are shown in map view, new OIDC options, lots of quality improvements including for accessibility and security. Plus more than can fit in this short text. Thanks to everyone for the contributions! 💡🚂

Aussie for cached data:
> Kayshed dah tuh

Having a chat about the new caching system that’s being added to #kubernetes #headlamp

To a New Yorker
> Kasht Day tuh

I replied to the bloke from London
> Cash’d Day uh

I code switched between different pronunciations. I realized at the end how funny that would have been to hear. But no one said anything… so.

> Dee DAHtah wars ge-cached.
Not even dropping some denglish phased them.

> Deh dah-tah was cach-ed.
With porteño flair… no reaction.

Well, well, well… #haptic movies are awesome.

I’m hoping to build a cob house. Pre Columbian architecture (think Gaudi curves and nature elements with a #handmade feel) some of it is remarkably similar to some old #cob / #thatched roof homes in England. To hobbit in. I did help build part of a cob wall once… it was in a warehouse for a music studio. Prior to today it was going to be an A frame triangle/alpine style house… so who knows in the end what will happen. But I love the sculptural elements this will afford.

The two mentors are super nice professionals.

Headlamp is a #Kubernetes UI that supports plugins for #CNCF projects like #Flux, #KEDA, and Falco. This project will focus on conducting UX audits, identifying usability issues, and proposing design improvements.

I'm going to be at #kubecon. At the maintainers summit beforehand, at the contribfest, and at the #headlamp project pavilion.

Contribfest session: https://kccnceu2025.sched.com/event/1td0n

I'm looking forward to connecting with folks working on different projects. People have been quite busy building out Headlamp Kubernetes UIs for ecosystem tooling and standards like #gatewayapi #prometheus #keda #flux #minikube #backstage #inspektorgadget #flagger and #certmanager

I think South Americano is redundant right? Always assumed #Americano meant south.

Anyway, Americano with ice is my go to #coffee on hot days.
(Maybe with Yuzu occasionally)

Just waiting for a hot day now. #berlin

We are having a video call for the @headlamp #kubernetes UI project Thursday 23rd 5pm CET

Brought some chocolate from Amsterdam for the #headlamp (the #kubernetes UI) Contribfest session on Friday. It’s deeeeeelicious.

I’m going to the Contribfest sessions because you get to meet maintainers and learn how to change things. My favorite part of the conference really.

https://kccncna2024.sched.com/event/1hoxL/contribfest-hop-aboard-and-contribute-to-headlamp

Ps. If you tap the Contribfest label on that page you see the other sessions on Thursday/Friday.
PPs. The chocolate is totally legal (but maybe it shouldn’t be).

Picked up "Wicked Arts Assignments" last weekend, and it's been sitting beside me most of the week. There's an interesting foreword about assignment as artwork, with a digression into Fluxus instructions-as-art. (Fluxus by the way seems to be having a moment again, with at least one group at the Berlin Jazz Festival doing it.) It's a group work collection from around the world of interesting #art #assignments, which really are instructions-as-art. Page of words, page of photos. #Gishwhes vibes.

Hearing about how #systemd is using varlink (simple JSON IPC) at #allsystemsgo gave me actual hope for #linux usability awesomeness.

Talk answers what varlink is and the many many reasons it's better (vs DBUS). https://www.youtube.com/watch?v=emaVH2oWs2Y

"It's so useful that it's JSON, because for the first time if I strace a systemd system I can actually make sense of the IPC calls being done... and this alone is one of the killer features of varlink that you can understand your fucking system now-a-days."

Nice talk from @dongsupark about azure-init (a minimal provisioning agent written in Rust) how development happens and the journey getting it into different distros.

This evenings tutoring session messed about with #linoprints and #lettering using flower pedals. Hoping to do several more cutouts next week and use white ink on black. Probably the lettering #photography will make it into a projected #animation.

Loving #jscodeshift. It lets you write little refactor scripts for #JavaScript and #TypeScript

Managed to cobble something together pretty quickly that had a few little bugs That weren’t too hard to hack around. Didn’t even consult docs once, but will to learn more.

Maybe a bit better than hacky little regex/unix scripts. Not sure how it compares to #eslint fixers… would like to try that to compare.

#oneAPI / #SYCL 2020 / #DPC++ / #AdaptiveCpp Is starting to look pretty nice. I’m not sure if there is a story for mobile devices and older devices. It seems that OpenCL 1.2 isn’t enough for SYCL 2020, but unsure. Also not sure how Vulcan fits in here. It’s also unclear how it scales to smaller kernels and data. The API looks like kernel/buffer/queue. Not sure if you can queue up many kernels or if they can be pipelined.

How does the new IR that llvm is using fit in here? So many questions.

Liking Slow Productivity by Cal Newport. Especially the part on defining what even is productivity? A well timed book.

> Pseudo productivity, the use of visible activity as the primary means of approximating actual productive effort.

Which is a measure being used for much of the generative AI research… 1/

#slowproductivity

Of course in code review it got a "Wtf is this for?" (the real note was much more polite of course). Even with one line of commentary trying to explain it already there along with some tests. It needed an extra line of comment! All because #trickery

btw. if you look for this feature in the docs for COPY, it won't be apparent! Why? Because #trickery I mean it does tell you about wildcards in some detail. It just leaves out this one thing it can also be used for.

Glad to see #FramaC get a shout out from #AdaCore. #C is one language with tooling for using solvers to prove correctness. Glad to see competition here. They’re moving the whole industry forward.

Hacking on #rustup a bit for the first time, and noticed that system dependencies are still kind of an issue with #rust. As in, it dependended on a system dependency and failed out halfway through the build. But the error message with the required apt-get/yum got me going again. Not so bad really.

Ok, parrotjoy🦜🕹️ won my attention. Mainly because it’s the cutest. A colourful parrot with an old Nintendo-ish gamepad. It’s not an animated logo yet, but if you search for “dancing parrot videos” that’s the vibe we’re going for.

Hrmm. Last commit I did was from about 3 years ago! The pandemic really stalled this project.
