React Native: The Bridge is Out and Your App is OOM-Killed It was 3:00 AM on a Tuesday in 2021. I was the lead SRE for a fintech startup that had just launched a high-yield savings feature. We built the mobile app in react native because the “velocity” was supposed to be unmatched. We hit … Read more
The server fans aren’t just spinning; they are screaming, a high-pitched mechanical wail that echoes through the cold aisle, even though I’m sitting five hundred miles away from the nearest physical rack. On my screen, the load average on the primary API gateway is sitting at 412.04. The cursor in my terminal blinks with a … Read more

Kubernetes Services: Stop Treating Your Network Like a Magic Black Box It was 3:14 AM on a Tuesday in 2019. I was staring at a Grafana dashboard that looked like a heart attack. Our checkout service latency had spiked from 40ms to 12 seconds. We weren’t under a DDoS attack. We hadn’t even deployed new … Read more
I remember when servers had physical buttons you could press, and if something broke, you could smell the ozone. There was a dignity in the hum of a SCSI drive spinning up, a physical manifestation of data being moved by magnetism and sheer willpower. You knew exactly where your bits were. They were on that … Read more
It was 03:14 AM when the Prometheus alerts bypassed my ‘Do Not Disturb’ settings, and I knew exactly which piece of ‘python code’ was responsible. I didn’t even have to look at the Grafana dashboard to know that the worker-api-v2 pods were in a death spiral. My eyes were already burning from seventy-two hours of … Read more
javascript console.log([] == ![]); // true Look at that. Drink it in. That right there is the foundational rot of the web. In any sane universe, an empty array compared to the negation of an empty array should return `false`. But JavaScript isn’t sane. It’s a series of compromises, accidents, and "good enough" decisions made … Read more
The smell of ozone is the only thing that’s stayed the same. In 2008, it meant a capacitor had finally given up the ghost on a Dell PowerEdge R710. It was a sharp, metallic scent that cut through the recycled air of the data center, usually accompanied by the frantic, high-pitched whine of a 15k … Read more
It is 3:14 AM. The PagerDuty alert didn’t just wake me up; it vibrated my soul out of my body. The alert says service-auth-gateway is throwing 500s. I check the logs. It’s a library mismatch. Again. Some junior developer—let’s call him Kyle—pushed a “hotfix” that relied on a specific version of libssl that exists only … Read more
November 14, 1998. 03:14 AM. I woke up because the air in the hallway didn’t smell like the usual mix of damp cypress mulch and rodent bedding. It smelled like a soldering iron left face-down on a pile of pine shavings. I didn’t even put on shoes. I ran to the back room—the room you … Read more
