Your database monitors keep firing even though nothing is wrong? We hit the same problem: noisy IOPS alerts caused by predictable jobs. This post explains how we replaced brittle thresholds with an SLO-based approach that restored signal, eliminated noise, and stopped the monitor from "crying wolf."

Python’s async model is misunderstood, especially by engineers coming from JS or C#. In Python, awaiting a coroutine doesn’t yield to the event loop. Only tasks create concurrency. This post explains why that distinction matters and how it affects locking, design, and correctness.

Materialized views are powerful but painful to change. Here’s how we safely version, refresh, and migrate them without locking production or timing out deployments, plus the approach we use to avoid dangerous DROP/CREATE migrations.

We turned our pull request rules into small AI-powered linters using GitHub’s new actions/ai-inference. Each linter enforces one rule: catching risky changes before humans do, without regexes, static analysis, or friction.

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.
