We are stress testing @slack.dev at work by starting a thread where we discuss the weather in the UK. 🫠

Join Nico Vibert and Dan Finneran this Friday for a for a sneak peek at a lab demonstrating how #Tetragon can protect against an #OpenClaw agent trying to access or share private data. #eBPF & #Cilium Office Hours 📆 Friday, May 8, 9am ET / 3pm CEST 📺️ Join live: www.youtube.com/watch?v=G2R3...

So initially I started writing a service mesh (for fun), then everyone started talking about AI workloads. So here we are, a transparent gateway that can be applied to running workloads (no restart) that allows control between agents/workloads and an LLM. kube-gateway.io

When Heptio was acquired by VMware we had to give up our downtown Seattle office. We had just gotten a new light up sign for the reception and no one wanted it so it has been sitting in my garage for the past 8 years. I have space now so just hung it up and it is magnificent.

I love it when a plan comes together. Some years ago I sketched on how I would automatically join bare metal nodes to my k8s cluster with PXE and auto issued certificates. Today I wanted to add a node and I just had to update versions and it went well. #kubernetes #homelab youtu.be/Jr4AWyzDJPg

Docker can now run workloads inside a VM, we have now gone completely full circle at this point. 🫠

heh, eBPF is controlling your AI 🐝

I am two people. - One, doesn't like to implement too much logging in my applications to make things clearer. - Two, the one who has no idea why my application behaves that way.. because the logs don't report anything.

This Friday, join Nicolas Vibert and Daniel Finneran as they talk through the key trends 2026 will bring in #Kubernetes networking, security, and #eBPF! eBPF & Cilium Office Hours 📆 Friday, January 23, 3pm CET 📺 Join live: www.youtube.com/watch?v=xBex...

Existing AI workloads? A few annotations and I can now transparently change their behaviour, swap out models in their API calls and more. (Thanks to #eBPF)

Re-found the virtual machine manager project for Kubernetes from last year, this example has BeOS inside a kubernetes cluster ssh-ing out to the control plane to manage itself 😂. No CNI needed either thanks to eBPF.

Regardless of what the AI client is (GO, Python etc...) we can now ensure we jump in to the "existing" data path and manipulate any of the data in either direction 😀

Using eBPF 🐝 and some proxy magic 🪄 to change the model on the fly transparently to the AI workload. We can see the first responses from llama and subsequent ones from gemma (more emojis).

Two pods with their traffic being proxied (thx eBPF 🐝) through a gateway, one using kTLS and the other user-land TLS. 🔐

It finally happened, i'm doing something AI & eBPF. 🐝 🤖

isovalent.com/blog/post/ku... Another amazing KubeCon with the @isovalent.bsky.social crew! 🤩

This series of posts about restoring an IBM PS/1 2168 is a fantastic read! Building an ultimate 90s Doom machine 🤩 fabiensanglard.net/2168/

Getting the Heptio band back together 😀

Excellent afternoon talking about Kubernetes networking and Virtualisation on Kubernetes.

Just heard Kubernetes 2.0 is about to be announced. #kubecon

Come and replace me at @hiveit.co.uk! They're a lovely bunch of people with a real focus on improving user experience and accessibility. If you've got any questions about the role I'd be happy to have a chat. www.hiveit.co.uk/careers/seni...

Had a few bits of @kube-vip.bsky.social clothing made 🐙. All of it make me look like I work for a fish mongers. 🫠

Make egress traffic look like ingress allowed Loophole Labs leverage XDP to 12x the throughput of iptables, and all without kernel patches 📈 eBPF is freedom to rethink how the kernel works.

Anyone considering SIG-BOULDERING. 🧗🏻 next week at #kubecon

An eBPF Loophole: Using XDP for Egress Traffic XDP is Linux's fastest packet processor but only handles incoming traffic. We found a loophole in how the kernel determines packet direction to make it work for outgoing traffic too! Blog post with details 👇 loopholelabs.io/blog/xdp-for...

Managed 25 minutes in this thing before I was starting to overheat 🥵

Come join me in 20 minutes, rumour is i'll be doing this in Halloween Fancy Dress too (whilst writing eBPF code) 🧟‍♂️

Join @thebsdbox.co.uk this Friday to get hands on with eBPF and Kprobes. eBPF & Cilium Office Hours 📆 Friday, 31 October, 2pm GMT 🎥 Livestream: www.youtube.com/live/JMnG5Hf...

Capturing keystrokes through eBPF ⌨️

Another day another Kubernetes networking doesn't work "issue" because someone misspelt a selector and/or label. 🫠

Just finished the John Candy documentary. He was pretty much in movies of my time so it hit pretty hard. I’d recommend it.

**Using a Laptop as an HDMI Monitor for an SBC** Wrote up some quick notes on how I use HDMI to USB capture cards to breathe new life into old laptops as HDMI monitors for my single board computers (SBCs). danielmangum.com/posts/laptop...

Pretty close to the episode of Brookyln nine nine where they go undercover in the library.

Been wanting to play with in kernel (kTLS) for a while, my mTLS proxy for encrypted pods now moves all encryption into the kernel 🤩

Came back for 13 local legends in the Peak District this weekend.

Unacceptable… immediately had to get on my bike to rectify the situation.

Live footage of me configuring a Cisco switch tomorrow on eCHO 😑

Spent a good 50 mins queuing for the Star Wars ride at Disney, Oscar (who is 5) repeatedly referred to the “lightswords” for the duration and refused to be corrected. Pretty surprised we survived the queue.

We've just announced the next Cloud Native and Kubernetes Edinburgh event, back after a bit of a break over summer with an absolute banger of a meetup that includes the one and only @thebsdbox.co.uk www.meetup.com/cloud-native...

I have my ducks in a row.

Sheffield was looking pretty epic in the sun yesterday evening.

Spotted @edera.dev

Watching a documentary and I’m pretty sure that’s the infinity gauntlet. 😬
