I spent MOST of my #kubecon talking to all the project maintainers, contributors at the project pavilion trying to learn about different CNCF projects, challenges they face etc. Here are the projects I feel most enthusiastic about for the next year 1. Cilium 2. Falco 3. Inspektor Gadget

Remind me again, who tf decided that templating out deeply nested YAML files was a wise idea? #HELLm

Case study: ESnet’s success with Cilium demonstrates that IPv6-only Kubernetes deployments are not only viable, but also work exceptionally well at government scale. This has provided a blueprint for other national laboratories facing similar mandates. Read more: www.cncf.io/case-studies...

What's been sitting in my Obsidian notes for over a year now, I finally took the time to put it up on my blog. I have a few more blog posts coming up as part of this series. #kubernetes #ipv6 #cilium netops2devops.net/series/kuber...

Really looking forward to this event! #kubernetes #cilium #ipv6 #kubecon

the new @golang.org 1.25.3 release does not seem to be available on MacOS via Homebrew yet? 🤔

I enjoyed reading the first few chapters in antonz.org/go-concurren... so much that I ended up purchasing the eBook 😁 It's just $10 which is a small token of appreciation for all that @antonz.org gives to the #go community for free! Plus now I get to solve all the exercises in the book. 😋

A couple of awesome resources which I came across as I was learning concurrency patterns in #go 1. Gist of Go by @antonz.org antonz.org/go-concurren... 2. Interactive guide to concurrency patterns by Richard Chukwu concurrency.rocks

I have never been a professional C/C++ programmer by trade and maybe that's why I don't understand this but after doing some beginner level exercises with #rust I don't get all the fuss around how borrower/checker rules make it complicated. Sure, it feels lot more verbose. Even more than #go

Critical thinking, curiosity and the drive to go deeper into the stack to learn something in & out appears to be diminishing as engineers become more dependent on AI generated content. People who were once "engineers" are now becoming "operators"

For anyone using or interested in running @cilium.io as standalone NAT46x64Gateway I have updated my blog post for the latest cilium v1.18.x releases. netops2devops.net/posts/cilium...

I dig the new updates in #iTerm2 3.6.x with the in-terminal browser, new icons. Feels more modern.

📣 New Blog Post Apparently, there are a few gotcha's when trying to checkpoint a running pod in #k3s which I learnt the hard way. I documented my findings in the blog post. #criu #kubernetes #forensics netops2devops.net/posts/checkp...

Whoever created #hubble for @cilium.io @isovalent.bsky.social should be given a gold medal. You have my utmost respect 🫡 Debugging Kubernetes networking issues has never been this easy.

The schedule for #CiliumCon is live! It features talks and end user stories on IPv6, #Cilium Mesh, DNS in #eBPF from companies like Microsoft, SeatGeek, ESnet, and more. Register now and join the community Nov 10 in Atlanta during #KubeCon NA: colocatedeventsna2025.sched.com/overview/typ...

CiliumCon schedule is out now From IPv6 only at ESNet to parsing DNS in eBPF at Microsoft to combining Cilium, Hubble, and Tetragon at Google to getting a service mesh into production in 90 days at SeatGeek colocatedeventsna2025.sched.com/overview/typ...

After struggling with embedding Rego inside YAML on top of having to write constraint template, then a constraint file just to create 1 basic admission policy, I am switching teams from #Gatekeeper to #Kyverno and as it turns out ..

The nano textured display with a slight matte finish on the new MacBook Pro laptops is just 🔥 Totally worth the $$$

#Kubernetes tends to seem more complex from the outside than it truly is once you realize it's just an API server managing the infra.

I am really starting to appreciate how @openpolicyagent.bsky.social docs have been re-organized in the recent update!

Is pkg.go.dev down? #golang

Upcoming changes in #Cilium 1.18.0 will bring significant improvements for operating #Kubernetes in #IPv6 only networks! One big ticket item is that now you can use the default tunnel mode with an IPv6 only underlay. I shared my configs in GitHub issue comments github.com/cilium/ciliu...

While #Cilium is most commonly used as a CNI, not much has been documented about its capabilities outside of #Kubernetes, specially as a standalone NAT46x64 gateway for #IPv6 only networks. netops2devops.net/posts/cilium...

I've been learning some concurrency in #Go using goroutines so I wrote a really dumb program that launches a workerpool to clone all publicly available repositories of an organization from Github. The obvious natural step next is to feed those repos to a secret scanning tool such as #gitleaks 😂

Most engineers who level up and eventually become executives usually drift away from their engineering grassroots as they become less hands on and focus more on business. But then there are people like Mitchell Hashimoto who still enjoy getting into the weeds and for that he has my respect 🫡

As someone new to #Golang (who is still very much learning) so far I have gotten a LOT of value from www.practical-go-lessons.com After reading almost half of the ebook online (for free) I started felt guilty and ended up purchasing the e-Book. Totally worth it in my opinion.

As a newbie to #golang I still don't understand how Generics are useful 🤔 Everything I need seems to be doable just with interfaces, types and methods. Maybe it will click later on.

Just got this in mail 😍 Looking forward to reading this gem. #Go #systems

I have a lot more content on #IPv6 #Cilium #Kubernetes #Golang sitting in my Obsidian notes but requires a little brush up before publishing😅 I hope to publish more soon but here's a start. netops2devops.net/posts/kind-m...

Learning #Golang has rekindled my interest in #DistributedSystems internals. I want to go deeper into that space. While I have extensive operational knowledge but not much academic depth. Any recommendations on where to start?

A four letter word that adds bureaucracy and slows down growth, speed and efficiency of getting work done in an engineering centric organization - #ITIL

How am I supposed to know which packages (like bufio etc.) contain implementations of an interface (like io.Reader, io.Writer) in #Go? I love the simplicity and beauty of the language but navigating the official docs has been a nightmare.

I'm a tad disappointed with how O'reilly's book "Learning Go 2nd ed." explains the type system in #Golang. They couldn't have explained it in a more convoluted way. But maybe that's just my opinion.

The masochistic side of me wants to ditch VSCode and move over my development environment to #neovim with #ghostty

At a first glance using `any` aka. an empty interface{} in #golang seems quite powerful cuz it provides flexibility (just like Python) but since Go is a strongly typed language, trying to to work around it is considered unidiomatic.

Last night I was scratching my head trying to debug why my #golang program was causing runtime panic when implementing an interface. After making some changes now I am debugging the same program except this time I am scratching my head trying to figure out how is it working?

Hmm.. at a surface level interfaces in Go feel like abstract classes in Python (but with some caveats) #golang

Started 2025 by diving deeper into closures in #golang and coming from a Python world, it took me a solid minute to understand the nuances with anonymous functions🤯 What is the output when `SumClosure(10, 20)` in each case? Try answering and maybe you can also get SumClosure 🤪

Something interesting to me about software companies (which I'll classify as companies where software engineers make up a nontrivial portion of their employees) is how they go about deciding whether to "build" or to "buy".

Coming from a Python world I couldn’t help but miss not having a ‘while’ keyword in #Golang for the #AdventOfCode Day3 challenge

Joining my fellow Gophers, I solved day 1 challenges #Golang #AdventOfCode github.com/netops2devop...
