I now have a Spark server that builds and tests my vLLM Docker image in CI against real models. This will be the first and last time this Spark touches grass. Post: technotim.com/posts/vllm-g... Huge thanks to NVIDIA for supporting this project

After a long hiatus, I finally had some time to put into my k3s-ansible repo that helps you bootstrap a Kubernetes cluster in minutes. I have CI working again and I can merge in confidence! k3s_version: v1.36.2+k3s1 github.com/timothystewa...

I tested a bunch of 10-inch mini-rack accessories, including cooling, power, displays, a network KVM, and even a compact UPS. Here’s what actually worked: youtu.be/ARN0PtHHKoM

I no longer only play a network engineer on YouTube. I helped transform a local nonprofit's network from this mess into something clean, documented, and maintainable. Don’t let anyone tell you homelab skills aren’t transferable.

If you're running an NVIDIA Spark or any of the clones with a GB10 (ASUS, Lenovo, Dell, HP, MSI, Gigabyte, etc) for local AI. I built a Docker image for it with the latest VLLM and all its component so that you don't have to. No need to wait weeks for NVIDIA to do it. github.com/timothystewa...

I wrote up my COMPUTEX 2026 takeaways. It was my first COMPUTEX, and I expected AI to be everywhere. I did not expect it to be almost everything. I also found mini PCs, NAS hardware, KVMs, Noctua, Seasonic, and Open Source Taiwan. technotim.com/posts/comput... #COMPUTEX2026 #Homelab #LocalAI

I wanted to see how good local AI has actually gotten, so I built a mini AI cluster on my desk and tested it with a real coding workflow. vLLM, OpenCode, NCCL, power monitoring, and open weight models. youtu.be/K2IGHj7KQoM

Just a heads up if you are updating Proxmox to kernel 7.0.0-3-pve. Some LXCs might not be compatible with that kernel version. VMs of course are not affected because they are fully isolated. To be clear you should update to the latest kernel, just be sure to check your LXCs afterwards.

Last night I had a dream that I traveled back in time to 2003. I couldn't figure out where I parked my DeLorean so I was stuck there. The scariest thing about being in 2003 in my dream was that when I looked at my phone it said I was connected at 3G.

After a month of troubleshooting my network, it ended up being a loose connection. Such a great sight to see!
