Hello all! You may have seen Cisco has performed some layoffs recently. My role in Cisco's DevNet team, a group focused on developer advocacy, network programmability and API quality was eliminated. I’m seeking a new role and would appreciate your support. If you hear of any opportunities or just want to catch up, please send me a message or comment below. I’d love to reconnect! About me & what I’m looking for: 💼 I’m looking for Director of Information Technology and Distinguished Engineer roles. 🌎 I’m open to roles in Raleigh, but flexible if the opportunity is right. ⭐ If you've been to a CiscoLive conference or followed my posts here you've seen some breadcrumbs of the kind of work I do in Network Management, Automation, Orchestration, Network Programmability and Observability.

GitHub Codespaces, along with tools like NetLab and ContainerLab make it easy to create and share labs. netautlabs.net has the goal of sharing network automation labs open source. Hopefully, many more labs are coming soon.

I just returned from the #AutoCon1 conference and had an incredible time! 🚀 I’ve published a new blog post, "From X25 to Kubernetes: Key Takeaways from AutoCon1," where I summarize my key findings and share my perspective on some popular discussions. lnkd.in/eQNcgnur

After diligent effort, we are pleased to announce the publication of the inaugural draft of YANG NG (Next Generation) on April 1st. infrastructureascode.ch/yang_ng.html #NetworkAutomation #YANG

How are you utilizing Generative AI?

Delving into Ansible basics with my students - is vital, even if it's not my top pick. Understanding its fundamentals and limitations is crucial in today's automation landscape. Here's a collaborative drawing we did together to visualize its concepts. #Ansible #networkautomation

🚀 Loving #Pydantic! 😊 Version 2's BeforeValidator and AliasPath are game-changers, making data structure transformations a breeze. Excited about the efficiency and joy it brings to #Python #NetworkAutomation! 💻✨

#pytest has 1311 plugins listed on their documentation. 🤯 docs.pytest.org/en/latest/refe… And now, Network Unit Testing System (NUTS) is also listed 😉 github.com/network-unit-t…

WEmulate (wemulate.github.io/wemulate/), a simple and modern WAN emulator, can now also be used in a container. I created a demo setup with @go_containerlab to demonstrate and try it. github.com/wemulate/wemul…

💣 3...2...1... New release! containerlab.dev/rn/0.44/ Containerlab 0.44 brings goodies: 1 Link impairments using tools netem command allows you to make your link stutter like if you're using an "ISP" your college friend built and sold to the whole dorm in 90s

Most likely, something big is coming soon.

For an easy way to try NUTS, I created a @go_containerlab demo. It is based on the example 5-stage Clos fabric topology. It uses the NAPALM srlinux driver. github.com/network-unit-t… If this post gets 100 likes, I will create gNMI-based test cases. 😉

!!! Network Unit Test System (NUTS) version 3.2.0 released. !!!🥳 github.com/network-unit-t… Finally, "groups" and "tags" can be used to create tests for multiple devices with a single test definition. #pytest #plugin #network #testing #nornir

@ntdvps @arp242_martin I think we [(need to be)|are] aware of this peculiarities. I still prefer YAML. And we should anyway always verify the input. I can still not believe why we see so little JSON Schema for YAML. It's really simple and nice infrastructureascode.ch/yaml_validatio…

This is an excellent summary of YAML peculiarities by @arp242_martin arp242.net/yaml-config.ht… But I don't think I share the sentiment of "don't use YAML". These standard fallacies like `yes->True` and `013->octal` are so rare compared to software bugs in the business logic, almost negligible.

Huge! Pydantic V2.0 is out. Huge thanks for the great work.
