After a year and a half of blood, sweat, and tears, our book ‘Network Automation with Go’ is finally getting published. 🗂️ Repository: #network-automation-with-go" target="_blank" rel="nofollow noopener">github.com/PacktPublishin… 📙 Amazon: amazon.com/dp/1800560923 📙 Packt: packtpub.com/product/networ… #automation #network #networkautomation #golang

@Marlex Where are you?

Hello #Gophercon!

No one loves the YANG data modeling language, but we are stuck with it in networking. Full practical guide 👉

LLMs feel like a black box, so I built my own #ChatGPT clone in Go #golang and #htmx. Full write up 👉

@ntdvps What’s the plan re: SROS vs SR Linux? I’d love to run the latter everywhere, but my very limited understanding is that’s not possible today.

I mean c'mon, I can sweeten the pill with the colorful tetris on SR Linux. Deal?

I really wish netengs in the SP/Ent markets wouldn't be so rigid/stubborn when it comes to the CLI. Yes, I understand the desire (and operational reasons) to exercise your muscle memory of wr mem all the things, but we did change the CLI for a reason, not because we wanted to make your lives harder — quite the opposite. You don't open a .go file and complain "oh I can't use print() here, who designed that shit?". It is painful to be an old dog and learn new tricks, I know, but if these new tricks outperform the old ones you learned - don't shy away from being open to learn them

I've got some networking books to give away. Pick up in person from Eastbourne or happy to post within UK. Send me a DM if interested.

@John_Capobianco For writing anything, big fan.

@John_Capobianco GPS, TCP, Email and C say hi 😈

You don’t use tech from 1970 to solve problems in 2024 VS Code will change your life in terms of sheer productivity Add copilot on top of that Docker extensions Kubernetes extensions Remote SSH Ubuntu terminal Git integrations and beyond Extension previews

Linux computer networking interviews are probably the hardest to prepare for due to the lack of up-to-date practical materials. Books usually provide only basics. In my new posts I tried to address IPv4 and IPv6 dual-stack apps, resolvers and internals biriukov.dev/docs/resolver-…

@IPvSean @CrowdStrike @Microsoft All good. Small accident at home, nothing compared to the chaos in the Hostpital experiencing a “the system is down”

@_nleiva @CrowdStrike @Microsoft Yikes! Hope everything is OK!

@LeadBlackTech FYI @chadell0 Network Programmability and Automation in this bundle

@ntdvps This is why they came up with Execution Environments (+ ansible-navigator)

The way I do my ansible ✅ hermetic reproducibility, same ansible version all the time ✅ zero install harassment. No deps hell ✅ OS agnostic, ~whenever I want to run - it runs ✅ Easy ansible version switch. Change a tag string and you're off And yes, I am building/maintaining these ansible containers for some recent Ansible versions that use different Python backends at github.com/srl-labs/ansib…

@nickrusso42518 I struggle with this one. In spanish we have ‘aprovechar’, which you can use on everyday conversations. I like Michael’s suggestions in the responses.

Is there a verb for "take advantage of", positively connoted? eg: The 2024 SuperCar takes advantage of improvements from the 2023 with respect to features X Y and Z. I guess "leverages" but it seems very corporate.

@IPvSean @leogallegored Red glasses, my legacy :-)

Cool dudes at #RedHat Summit

Hi folks. One of the groups that I am the tech lead has two network engineering positions available — based out of Atlanta. The group is responsible for rethinking how we define, test and deploy network devices. 1/3

This is probably the most approachable Linux network programming resource I’ve come across yet: beej.us/guide/bgnet/

If you wonder what happens when you have a headless Service in Kubernetes with 10k endpoints gist.github.com/aojea/32aeaa86… and how this ended finding (and fixing) a bug in golang github.com/golang/go/issu…

@Itsuugo Thanks for sharing, really interesting. It’s always DNS :-)

@iximiuz @SuperbPhoenix It gives you context of what a CNI plugin in k8s does (Bash -> Go). For reference, this is an example that adds Liz’s container from scratch to a network bridge in a different net namespace: #my-cni-plugin" target="_blank" rel="nofollow noopener">github.com/nleiva/cni-plu…
