Title: March 9, 2020: A Week of Debugging and Disruption

---

Today is March 9, 2020. It’s a typical weekday for me as an engineer, but the world around us is already starting to change in ways that will reverberate through our industry for years to come.

Morning: Debugging Kubernetes Headaches

I woke up at my desk, staring at a Kubernetes deployment failure on one of our critical services. The logs were filled with error messages about network policies and ingress rules that seemed to be misconfigured or not properly propagated. I had been meaning to clean up the networking setup for weeks, but somehow never got around to it.

After several frustrating hours of digging through code, manifests, and cluster configurations, I realized the issue was a subtle mismatch in the namespace settings between our staging and production environments. Once I fixed that, the service started rolling out smoothly across all clusters. Phew!

Midday: Learning About eBPF

In the afternoon, I dove into some reading about eBPF (Extended Berkeley Packet Filter). I’ve been meaning to learn more about this powerful tool for performance monitoring and networking. It’s fascinating how it can provide low-level insights without invasive hooks or changes in user space.

I set up a small demo on our staging cluster to monitor network traffic using BPF programs. The results were enlightening, but also made me realize just how complex and nuanced these tools are. I spent the next few hours tweaking some sample scripts before finally getting something useful running.

Evening: Navigating Remote-First Work

As I wrapped up my day, I thought about how things might change in the coming weeks. The news about Zoom has been all over Hacker News this month, and it’s not hard to imagine a surge in demand for remote work tools. Our team is already scaling our infrastructure to support more remote developers, but there are still challenges.

One of our SREs mentioned that we need to rethink how we manage backups and disaster recovery when everything moves off-site. The usual practices might no longer apply, so it’s time to start planning and testing for a remote-first world.

Night: Reflecting on the State of Tech

As I settled in for the night, I couldn’t help but reflect on all that has happened this month. The pandemic declaration feels surreal—hard to believe that just weeks ago, everyone was working their usual routines.

The news about SETI@home shutting down after 21 years tugs at a sense of nostalgia. It’s a reminder of the early days of distributed computing and the excitement surrounding projects like this. Now, with platforms like ArgoCD and Flux GitOps maturing, there are new frontiers to explore.

On a personal level, I’m glad we’ve been able to adapt so quickly here at work. The shift to remote-first is challenging but also exciting. It’s given us an opportunity to rethink our infrastructure and processes in ways that might have been harder during normal times.

2020 turned out to be quite the year already. Who knew it would start with such a bang? Here’s to hoping for smoother sailing as we move forward!
