Finally started redesigning/updating my personal webpage: ubaumann.ch

My smallest hotel room so far.

DCD was a pleasant experience and unfolded a new world of "how to build your own datacenter" from a physical location perspective. Saw some interesting cooling systems. I will never use this knowledge. 🤣

API first for first-semester students in the Network Foundation module commencing next month.

It's a strange feeling if the CI/CD runs without any failures when migrating a Python project from Poetry to UV. Not sure it can really be that smooth. 🤔 github.com/Infrastructu...

Network Slicing + Two Pizza Teams = Double-stuffed RJ45 Ports #networking: 🌐 AWS NAT Gateway interactive blog 🗺️ D2 to visualise networks 🎓 k8s for Network Engineers 🤔 Is Cisco NDFC really ACI? 🐍 BGP on ceEOS with Python 🤘 fck-nat for AWS VPCs 💀 Knowledge work is dying reloadin.net/p/two-pizza-...

I finally published a new blog post on creating network topologies using the D2 diagramming language! If you're familiar with GraphViz or Mermaid, it's worth exploring what D2 has to offer, including modern syntax, icons, interactivity, and more. infrastructureascode.ch/d2-network-t...

The moment you execute a command and expect it to fail, but it just works. And now, you need to verify if it worked.

Unofficial hallway track from #AutoCon3 networkautomagic.net/podcast/na004/

Today, drinking coffee and Cisco are paying

What a cool project. GitOps for Infrahub Artefacts. The operator allows deploying any CRD on a k8s cluster, obeying all 4 OpenGitOps principles. github.com/infrahub-ope...

#autocon3 is starting strong with 2 days of workshops @infrastructureascode.ch and @steinzi.bsky.social running the show to teach everyone how to use NUTS and Pytest

Convert your MkDocs repo into a MCP server providing the markdown files as resources github.com/ubaumann/mkd...

Have you ever tried building a Terraform provider for a dynamic schema? @marcom4rtinez.bsky.social did! Marco created a strategy to generate tailored Terraform providers for dynamic Infrahub schemas, detailing the build and usage process in two blog posts. infrastructureascode.ch/author/mmart...

Is it worth it to recertify?

Ever wanted to provide containerlab as a service to your team? Two students are doing great work with antimony, providing a modern frontend and backend to integrate with containerlab and clabernetes.

A new podcast was just published on Network Automagic. Steinz, Marco and I are discussing the Network Unit Testing System (NUTS). networkautomagic.net/podcast/na003/

The feeling when the lab finally works after you realise you forgot the "vxlan encapsulation ipv6" command.

It feels like spring.

I couldn't decide whether to give a workshop or talk at #AutoCon3. So, I guess I will do both.

I don't want to know how much energy was used to train a model capable of "painting" me so well.

It's funny to see Cisco teaching on Cisco U. how important it is to mitigate vendor lock-in regarding AI stacks.

I like the jetbrains.com cookie banner!

Ingress is dead, long live....Gateway API Luckily there is a community written tool to make the transition seamless. Find out how to use ingress2gateway in this blog from Christine Kim

The University GitLab service announced a 64-hour maintenance window. I'm not sure how I should feel about it.

Taking Pydantify further and creating more elaborated automation with YANG-based pydantic classes www.youtube.com/watch?v=CM3s...

It's a nice feeling when you finally cross the 80% line

After two hours of searching for my robot vacuum cleaner in the apartment, I nearly gave up.

I am listening to the draft-iab-nemops-workshop-report-00. Works really well.

These are some huge dependencies.

Was great to collab with @infrastructureascode.ch and Dan Peachey on making pydantify work with SR Linux YANG models. I love this infinity times more than templating youtu.be/oClamTj4LiY

Pydantify v0.7.0 has been released 🥳🥳🥳 github.com/pydantify/py... Convert YANG models into @pydantic.dev models and generate your RESTCON/NTCONF/gNMI payload in a Pythonic way. Say goodbye to generating structured data with jinja2.

Today, around 100 students had to write the Computer Networking 1 exam. They definitely learned something.

> Hello Urs, > Your CKA Certification is scheduled to expire on 2025-04-14.

By the way, I am looking for freelancers who could fix my biggest gripe with @squidfunk.bsky.social 's mkdocs-material - non expandable code blocks github.com/squidfunk/mk... for $$

After my MSc in computer science studies its time for a new challenge! Looking for jobs in Singapore or fully Remote 🔎 www.linkedin.com/feed/update/...

I developed a simple proof of concept using Pydantic and Faker to generate synthetic data for L2 or L3 interfaces.

So far I am happy with the "workspaces" feature of UV. Playing around with mono-repo. Are you a fan of mono-repos and why? docs.astral.sh/uv/concepts/...

Starting to look like a workplace. There is still a lot of work to do. Now, I need to look closer to the OBS settings.

Did you know that testing the streamlit frontend is easy?

I am thinking of giving my home office a face-lifting and producing some videos. What does your video/audio setup look like? PS: is the 20% cut from Onlyfans acceptable?

I still need to do some prompt template engineering. The result is okay, but the agent did not use the provided tool as I intended. xD

I'm a bit late to the party, but after running sed 's/netbox/infrahub/g', I'm now close to getting it to work with Infrahub. github.com/ubaumann/inf...

I have just created a demo for the new Nornir conditional runner. github.com/Infrastructu... Trying to make a quick video...

After 1,234 days of trying, I still haven’t progressed in learning another language.

💡 @infrastructureascode.ch asked a great question a few weeks ago in the Network Automation Forum slack channel. When is it "using" AI and when is it "doing" AI? I took some time to write out some of my thoughts 👉 wcollins.io/posts/2024/a... #ArtificialIntelligence #MachineLearning

If pushing the door as hard as possible doesn’t work, take a moment to step back and consider a different approach. Try pulling the door instead; it might do the trick. Or the door is just locked.

Next time, I might rent a bicycle. Lovely town.

Boulder is a lovely little town.

The "Network Automation Folks" Starter Pack is constantly growing. It's nice to see more and more people here. After playing around, I now have a YAML file you can update with a pull request to add someone to the list. github.com/ubaumann/bsk... go.bsky.app/N9nHqzg
