Disaster Recovery Drills That Actually Work

Most DR Drills Are Theater Someone schedules a meeting. A few senior engineers walk through a runbook. Everyone agrees "yes, we could do this" and marks it complete. Then the real disaster hits and nobody remembers the procedure, the runbook is 2 years out of date, and half the backup systems don't work. Real DR drills test whether your team can actually recover, not whether they can talk about recovery. Level 1: Tabletop Walk through a scenario on paper Identify missing runbooks Find ownershi

SSG vs SSR vs CSR in Next.js: Choosing the Right Rendering Strategy for SEO

Is Next.js Really SEO-Friendly? Understanding SSG, SSR, ISR and CSR Thanks @opacedigitalagency for the valuable suggestion. While exploring this topic further, I researched how different rendering strategies in Next.js impact SEO, performance, and user experience. Many developers say: "Next.js is SEO-friendly by default." But the reality is more interesting. Next.js gives developers multiple rendering strategies, and the actual SEO benefits depend on choosing the right approach for the right t

Your rules file only grows. Here's how to find the rules that do nothing

This is part 3 of a series on project rules for AI coding agents. Part 1 covered how Cursor, Claude Code, and Codex load your rules. Part 2 covered enforcing rules with hooks. This one covers the part almost nobody does: figuring out which of your rules are dead weight. Nearly every long-lived rules file I've seen has the same life story. It starts as five lines. An agent does something annoying, someone adds a rule. A bug slips through, someone adds a rule. Six months later it's 40 rules, and n

There are around 10 independent PDF engines, and I built a new one from scratch.

I'm a student who mostly built little apps for myself. About 14 months ago I needed to edit a random PDF and couldn't find a good web tool that actually edits them. It made me wonder: billions of people use PDFs for work, school, and legal documents, so why can almost no web service truly edit them? So I tried to build one, and failed. I didn't understand why it was so hard. I tried combining pdf.js and jsPDF but kept hitting walls. Then it clicked: most JavaScript PDF libraries only do two thin

JavaScript Atomics and SharedArrayBuffer in 2026: Practical Patterns for Cross-Worker State

JavaScript Atomics and SharedArrayBuffer in 2026: Practical Patterns for Cross-Worker State This article was written with the assistance of AI, under human supervision and review. Most cross-worker communication problems stem from treating workers as isolated processes when the workload demands shared state. Teams reach for postMessage by default, serialize multi-megabyte data structures on every frame, and watch their real-time audio pipelines stutter under 100ms message latency. The browser

I Built a Browser to Solve a Problem Every Developer and QA Engineer Faces

If you've ever worked on an application with multiple user roles, you've probably experienced this. You log in as an Administrator. Then you need to test the Manager. So you log out. Log in as the Customer. Log out again. Then the Support Agent. And maybe another Guest account. Before long, your browser has turned into a collection of Incognito windows, multiple browser profiles, different browsers, or entirely different devices. I reached a point where I was testing an application with five dif

Best alternatives to Heroku in 2026

Heroku pioneered the shape of what a small team expects from a hosting platform. Push code to Git, get a running app, add a Postgres or a Redis with one command, worry about the product rather than the infrastructure. That shape has since become the industry default, but the platform that invented it has been steadily losing teams since the 2022 when the free-tier was removed, by 2026 much of the ecosystem seems to have moved on. This post walks through several platforms that are worth consideri
