Cilium Ingress Dropped as Martian Source

Tue, 04 Aug 2026 00:00:00 -0500

The symptom

Single-node cluster at home. Cilium as the CNI, doing ingress and L2 load balancing. The goal was mundane: https://api.llama.internal/ should hit a llamacpp pod through Cilium’s ingress.

It didn’t. From any machine on my LAN:

$ curl -k --max-time 15 https://api.llama.internal/
curl: (28) Connection timed out after 15004 milliseconds

The connection never even got to TLS. But here’s the part that sent me down a three-hour rabbit hole: from the node itself, it worked fine.

Vim for Writers

Most Vim cheat sheets are written for developers. Visual block mode, macros, ctags. Useful stuff, but not what you need when the buffer is full of prose.

I put together a cheat sheet focused on writing. Sentence and paragraph motion, text objects like cis and cip, gj/gk for wrapped lines. The commands that matter when you’re editing words, not code.

I’ve been using Vim for decades. Decades I tell you! And I did not know ( and ) move by sentence until I made this thing. It’s right there in :help motion.

My First Youtube Video

I finally uploaded my first Youtube video. I’ve been meaning to start working on Youtube videos forever. I just clicked the button and recorded a quick tip on how to maintain eye contact with your camera when presenting. A big part of my day, as a Principal Solutions Architect at AWS, is talking to customers and our internal service teams. Customers rely on my knowledge and experience when advising them on decisions regarding AWS, Kubernetes, software engineering, and operations. It adds to the air of professionalism, if you will, when I can make small improvements on my audio, video, and communication skills.
