Integration Test Isolation in a Next.js App with Drizzle ORM
1. Introduction: The Complexity of Modern Integration Testing The evolution of web application architecture has precipitously increased the complexity of ensuring software quality. In the era of the monolithic, server-rendered application—typified by frameworks such as Ruby on Rails or early ASP.NET—testing strategies were relatively straightforward. The application ran in a single process, connected to a single relational database, and served HTML directly. Integration testing in such an environment was a solved problem: wrap the test in a database transaction, execute the logic, and roll back the transaction at the end of the test. This approach, often referred to as the “transactional rollback” strategy, provided a clean slate for every test case, ensuring isolation and determinism with minimal overhead.

Offline Encryption Using WebAuthn
I’ve been diving deep into browser-based cryptography lately, and implementing truly secure offline encryption is frustratingly complex. The core problem? Getting consistent key material across sessions without storing anything sensitive.

Loading tmux when loading shell
This is something I’ve had mixed success with in the past. I’ve had things that worked but not quite in the way I wanted them to, and other things that just didn’t work! (Try sticking an exec before an error in .zshrc, and you’ve just nerfed your shell startup!)

Server status monitor bash script
When managing multiple servers, keeping track of their availability is crucial. Building on an example from “Cybersecurity Ops with bash” by Paul Troncone, I’ve developed a bash script that provides a simple yet effective way to monitor server status across multiple hosts. Let’s break down how this script works and why it can be a valuable tool for system administrators.

Global find and replace with bash
I’m working on a server migration script (watch this space) where I need to do a global find and replace in a bunch of files on a VPS (Virtual Private Server). I’m currently reading a bbok called “Cybersecurity Ops with bash” by Paul Troncone, which has been a great resource for learning bash scripting, and I found a solution in the book that I can use to do the global find and replace:
