Discover how the double-asterisk recursive glob pattern evolved: from Zsh’s early 1990s innovation to Bash’s globstar and beyond, spreading into Python, Ruby, Git, and modern build tools.

How do you ship risky code without crossing your fingers? In this post, we explain how he ran old and new logic in parallel (“shadow shipping”) to validate behavior in production before rollout. Learn how this simple pattern turned feature-flag anxiety into data-driven confidence.

PostgreSQL doesn’t "ignore" your indexes, it just does the math differently. We dive into how the planner weighs cost, why it sometimes chooses sequential scans, and how we tuned our queries to make peace with it.

We built a "self-healing" system that fixes deprecated configs by opening PRs automatically. It worked like magic, until it didn't. Here's what we learned about the thin line between elegant automation and uncontrollable complexity.

TypeScript doesn’t run your code, but your bundler might think it does. Learn why marking your type imports with import type (and enabling `verbatimModuleSyntax`) makes your builds faster, cleaner, and more predictable.

AI can explain what code does — but not why it does it. This post explores how documentation is evolving in the age of AI, and why writing down human intent is becoming one of the most practical forms of AI alignment.

Floating versions like :latest, ^, and ~ promise convenience but deliver broken builds, hidden regressions, and supply chain risks. Here we explain why they undermine reproducibility and security and shows how to pin GitHub Actions, Docker images, and dependencies safely.

Permissions drift is real: scattered checks, forgotten filters, and data leaks. PostgreSQL’s Row Level Security (RLS) flips the script: pushing verification into the database for stronger safety, but with trade-offs in debugging and performance.

From Bors and Homu to Bulldozer, Kodiak, Mergify, and now GitHub and GitLab, merge queues have shaped how we keep main branches green. This article traces their history, why they emerged, and how they became a standard in modern software development.
