The Problem: Why Your Incident Timeline Is Lying to You The cruelest irony of on-call: the moment your system is most broken, your monitoring is slowest. I’ve been paged at 2am, fumbled through four different Grafana folders, opened three dashboards that were either stale, wrong service, or loading a 48-hour time range I forgot to … Read more
The Problem: Terraform’s BSL License Change Broke Our Pipeline Planning The BSL switch blindsided a lot of teams because it wasn’t a “you can’t use this anymore” announcement — it was more subtle than that. HashiCorp relicensed Terraform from MPL 2.0 to the Business Source License starting with v1.6, and the specific clause that made … Read more
The Problem: Your Dashboard Lies to You When You Need It Most The dashboard that fails you at 2am is always the one you trusted during business hours. Grafana loads fine when you’re doing capacity planning on a Tuesday afternoon — but the moment your error rate spikes and you actually need it, you’re sitting … Read more
Why I Started Looking for Terraform Alternatives (And You Probably Should Too) The BSL change hit differently than most license drama. In August 2023, HashiCorp moved Terraform from the Mozilla Public License 2.0 to the Business Source License 1.1 — and the key clause is this one: you can’t use Terraform to build a product … Read more
The Setup: Two Semesters, Two Languages, Very Different Pain The thing that surprised me most wasn’t which language students struggled with — it was when they struggled. TAing an intro CS course using Racket, I watched students hit a wall on recursion around week three, then suddenly click and start writing elegant list processors by … Read more
The Problem: Why Gradient Borders Are Annoyingly Hard in CSS The thing that trips up almost everyone is discovering that border-image simply refuses to respect border-radius. This isn’t a browser bug you can work around — it’s specified behavior in CSS. Combine border-image with border-radius: 16px and you get sharp corners, every time, in every … Read more
The Problem: Your CI/CD Pipeline Is Doing Too Much Kubernetes Babysitting The thing that finally broke me was watching our deploy pipeline sit at “Applying Terraform plan…” for 28 minutes straight. The actual application deploy — the thing the pipeline exists to do — took four minutes. We were spending 87% of our CI time … Read more
The Real Problem: Kafka’s Ops Burden Hits You on Day 2, Not Day 1 The trap is always the same: you spin up Kafka with Docker Compose in three hours, get a producer pushing messages, feel like a genius — then Monday rolls around and you’re staring at a ZooKeeper ensemble that’s split-brained, a consumer … Read more
The Problem That Started This: Bash Was Eating My Debugging Time The script that broke me was a deployment pipeline running inside an Alpine container — 200-ish lines of Bash handling S3 uploads, config templating, and health checks. On the third “silent deploy” in two weeks, where the script exited 0 but half the files … Read more
Why I Built This Instead of Using an App The thing that finally pushed me over the edge was discovering that my CGM app stores readings in a proprietary format, exports as a PDF (a PDF), and wants $12/month to show me a 90-day trend line. That’s data my body generated. I should be able … Read more
