@michalfita this is probably the best one to use with an nvidia card now: https://snapcraft.io/nemotron-3-nano

@michalfita I don't think we have an optimised model with AMD *yet*, but that's absolutely the goal.

We're trying to use our partner relationships to get optimised models for Nvidia, Intel, Ampere, Qualcomm, AMD, etc...

I think we have already got models out for Nvidia, Ampere and Intel […]

@michalfita we’re doing some interesting work at Canonical to try and make access to silicon-optimised models a bit simpler.

In reality this isn’t perfect yet either, but as this trend develops more and more more silicon will become more capable of running inference efficiently - we’re really […]

@michalfita yes, that’s probably true. In reality it would still be possible to build this with lower-tier or even free means (self hosted models), but it would definitely take longer.

@michalfita Difficult to say exactly. I currently have a Claude Code Max plan, and I wasn't tracking the token usage particularly carefully. There's no doubt that it would have been quite costly if I was on a more PAYG type arrangement with something like OpenRouter.

Brewlog: Coffee & Agents

My latest #blog outlines how I built a super-niche application for tracking my specialty #coffee brewing and consumption, but also marks some of the most complex work I've done with an agent to date.

Built in #Rust with Axum, backed by #SQlite and with a #TailwindCSS […]

Two great updates from the #Ubuntu team in the last few days!

The first from our Debcrafters team explains the work they're doing to modernise the infrastructure behind the Ubuntu archive with #Juju and charms […]

Over the past couple of days, there has been a lot of commentary about #Ubuntu and how it'll respond to California's new Digital Age Assurance Act (AB 1043), which will require operating systems to collect age information at account setup and expose an age “signal” to eligible applications from […]

Happy to confirm that I'll be attending #Kubecon EU 2026 this year. I'll be there from Mon-Wed, let me know if you want to meet up and talk #Ubuntu, cloud, Kubernetes, AI or just talk about excellent coffee ;-)

Gutted it’s taken this long but got my first proper trail ride of the year in today and riding around in the sun was just so great ☀️ 🚵

Resolute Snapshot 4 released Hello everyone, I’d like to announce the fourth (and the final!) successful publication of the monthly snapshot - Resolute Snapshot 4. You can find the images on cdimage.ubuntu.com, for instance: …and so on. 🙂 Few teams have already started to update release notes, which could be found at We’d like to remind you that these aren’t production-ready and should be seen as “throwaway artifacts” for now. Now that we’re in feature freeze, I’ll request y’all to start squashing al...

The fourth and final development snapshot of #Ubuntu 26.04 LTS was published last night!

The next will be a release candidate and then it's time for the real thing 🙂

Not long now until the closing keynote of Rust Nation UK where I’ll be talking about Rust adoption at scale with Ubuntu! 🦀 #RustNationUK

Excited to be speaking at #Rust Nation today!

Almost time to kick off AI Native Dev courtesy of @tessl_io!

I’ll be speaking about how Ubuntu can help AI during development, and used in production 🚀

Today I published an update on the #Canonical supported #upki project, which brings browser-grade Public Key Infrastructure to Linux through the efficient #CRLite data format, with the core revocation engine now functional and available to test!

Beyond current progress, this post explores […]

Post Quantum Support in Ubuntu 25.10 and the upcoming 26.04 LTS Background In 1994, Shor’s algorithm showed that widely deployed public-key systems RSA, DSA, and elliptic-curve cryptography would be vulnerable once sufficiently powerful quantum hardware becomes available. This realization triggered decades of research into alternative mathematical foundations for public-key cryptography. In 2016, NIST launched a public, multi-round standardization effort to evaluate and select quantum-resistant algorithms. After years of cryptanalysis and community review, ...

"Why we're saying goodbye to 'Software & Updates'"

Really excited to see a blog post from the #Ubuntu Desktop Director outlining our plans to simplify software management on Ubuntu - centered around the beautiful App Center work our team did in #Flutter […]

And then following that, I'm speaking in the afternoon keynote slot at Rust Nation UK!

Here I'll talk about Rust adoption at massive scale in Ubuntu. I'll cover the "Oxidizing Ubuntu" project, as well as all the places we're working in Rust, and working to improve the experience for Rust […]

Busy week of talks next week! I'm attending two different events in London...

First, I'll be presenting "Ubuntu for AI" at AI Native Dev, hosted by @tessl_io!

The event is right by Kings Cross station in London and you can find all the details at the link below. Would love to see as many of […]

Merge-o-Matic: Recent updates and future plans Hi everyone, Today I want to share an update on the work that has recently been happening on the Ubuntu Merge-o-Matic service, as well as some thoughts on where we could go from here. 1. What is Merge-o-Matic? As you probably know, Ubuntu is based on Debian. It means most of our packages come from there. We try to contribute fixes and improvements back upstream and to keep our packages “in sync” as much as possible, but we have to carry changes (which we also call “delta”) in some of our packa...

And the #Ubuntu Debcrafters team wrote about our tool to help merge packages from Debian -> Ubuntu, as well as some recommendations for its future! :)

[AI, LLMs]

Had a go this week at building a custom LLM-based agent for a specific task at work.

I built it in #Rust using the Rig crate, which I found to be very intuitive, and Gemini 3 Pro as the backend.

The agent has 3 tools, one for scraping a list on my Todoist account, one for gathering […]

BBQing in black tie last night for Burns Night.

We did a traditional burns night supper with haggis, neeps and tatties, but augmented with a nice piece of BBQ’d beef fillet.

I was already dressed when it needed cooking, though 😅
