P.01Command-line tools are underrated as developer products. TypeScript makes them maintainable. Here's the full picture: argument parsing, interactive prompts, output formatting, and distribution.
P.02The Date object has been broken for 30 years. Temporal is its replacement, now shipping in browsers and Node.js. Here's what actually changed and how to use it.
P.03Storybook 8 is faster and less painful to configure than it used to be. More importantly, the workflow shift it enables — building components in isolation — solves real problems on real teams.
P.04AI tools write code fast. TDD asks you to slow down and write tests first. These two impulses seem to be in tension. Here's how they actually work together.
P.05Standardized commit messages unlock automatic changelogs, version bumps, and release notes. Here's the full setup — from writing commits to shipping releases without manual steps.
P.06AI projects flood every portfolio. Here's what actually distinguishes a developer's work from the crowd — and why the way you document your decisions matters more than the tech stack you picked.
P.07Manifest V3 changed how Chrome extensions work. Here's what actually matters for developers building extensions today: service workers, declarativeNetRequest, and the gotchas nobody warns you about.
P.08DuckDB runs OLAP queries directly in your process, on files on your laptop, without a server. Here's how to use it and when it beats spinning up BigQuery or Redshift.
P.09Every agency project with a marketing team needs a CMS. The options have changed a lot. Here's how Sanity, Contentful, Strapi, and Payload stack up on the criteria that actually matter.
P.10The command line tools most developers use today are a decade old. Here's what's replaced them and why: terminals, Git UIs, shell configuration, and the small tools that compound into significant time savings.
P.11A growing class of AI agent frameworks can control a browser the way a human does — clicking, typing, navigating. Here's what works in production, what breaks, and when to actually reach for these tools.
P.12Go has real strengths for backend API work, and some persistent limitations. Here's what teams actually gain and give up when they choose it over Node.js or Python for web APIs.
P.13A hands-on comparison of Typesense, Meilisearch, and Algolia for production SaaS search in 2026 — covering self-hosting, performance, pricing, and real implementation patterns.
P.14A practical comparison of PostHog, Amplitude, and Mixpanel for SaaS teams in 2026 — covering pricing, self-hosting, event tracking patterns, and what metrics actually move products forward.
P.15How Zod became the standard for runtime type validation in TypeScript apps — API contracts, form validation, environment variables, and the patterns that make schemas a source of truth across your stack.
P.16OpenTelemetry is the observability standard now. Most tutorials show you how to install the SDK and emit traces. Fewer explain which signals actually matter for web applications and which add noise without helping you debug anything.
P.17Most E2E test suites start fast and grow painful. Playwright solves most of that, but only if you set it up right from the start. Here is what actually works in production.
P.18Password resets, invoices, and notification emails are infrastructure. Most developers treat them as an afterthought until a client asks why their welcome emails are disappearing. Here is the full picture.
P.19Most teams pick an analytics tool based on a free trial and then live with that choice for years. Here's an honest comparison of PostHog, Mixpanel, and Amplitude so you pick the right one before the data gets messy.
P.20When your AI agent needs to run the code it writes, you can't let it touch your production servers. Here's how the main isolation options work and when to use each.
P.21Most agency developers don't think about the license of npm packages they install until a client's legal team asks. Here is what the major licenses actually require and where the real risks sit.
P.22Bad documentation is usually not a writing problem — it's a maintenance problem. AI tools are changing the equation by making initial doc generation cheap and doc refresh practical at scale.
P.23Burnout among developers isn't new. But the specific pressures of 2026 — AI-driven productivity expectations, skills anxiety, and the blurring of output and identity — create a different texture of exhaustion.
P.24The Vercel AI SDK has become the default for building AI features in JavaScript apps. Here is what it actually does, how its core primitives work, and where the sharp edges still live.
P.25JavaScript error handling is broken by default — exceptions are untyped, async errors are easy to miss, and side effects are invisible in function signatures. Effect TS fixes all three. Here is how it works.
P.26Hallucination is not a bug that gets patched in the next model release. It is a property of how language models work. Here are the patterns that actually reduce it in production systems, and what they cost.
P.27Vuex was Vue's state management library for years. Pinia replaced it as the official recommendation and changed how Vue apps manage shared state. Here is how Pinia works and where it fits in a Vue 3 application.
P.28Hono started as a tiny router for Cloudflare Workers and grew into the default choice for edge APIs. Here is what it does well, where it fits, and why the 'runs everywhere' claim is actually true.
P.29Interaction to Next Paint replaced First Input Delay in 2024, and most sites still haven't caught up. INP is harder to optimize because it measures every interaction, not just the first one.
P.30Single-provider AI dependencies are a reliability risk. Routing layers like LiteLLM and OpenRouter let you fall back across providers, cap costs, and try smaller models first. Here is the architecture and when it actually matters.
P.31Neon separates storage from compute to make Postgres behave like a serverless resource. The branching feature is what actually changes the development workflow — here's how it works and when it's worth the migration.
P.32Client state is easy. Server state — data that lives on a backend, changes over time, and needs to stay in sync — is where most React apps make a mess. TanStack Query handles it without ceremony.
P.33k6 is a developer-friendly load testing tool with JavaScript scripting, CI integration, and clear metrics. Here's how to write meaningful load tests, interpret the results, and catch performance regressions before they reach production.
P.34Tauri 2.0 added iOS and Android support while keeping what made 1.x compelling: tiny binaries, Rust backend, and native OS webviews instead of a bundled Chromium. Here's how it works and when to use it.
P.35CodeRabbit, GitHub Copilot code review, and similar tools have changed the first-pass review. Here's what they actually catch, where they fail, and the workflow that combines both effectively.
P.36Python 3.14 shipped in October 2025. Seven months in, the features worth caring about have become clear. Here's what changed, what to upgrade for, and what to ignore.
P.37Leaked credentials are the most preventable category of security breach. Here is an honest look at when you need a dedicated secrets manager, which tool to pick, and what to do if you're still on .env files.
P.38Vitest runs faster, works natively with ESM and TypeScript, and uses the same API as Jest. If you're still on Jest in a Vite-based project, here's the case for switching and exactly how to do it.
P.39Biome is a Rust-based JavaScript toolchain that handles linting, formatting, and imports in a single binary. We've been running it in production projects since late 2025. Here's what the migration from ESLint and Prettier actually looks like.
P.40Code-first API development produces documentation as an afterthought. OpenAPI-first flips that: you write the spec, generate the server stubs and client SDKs, and enforce the contract at every layer. Here's how it works in practice.
P.41Background jobs that crash mid-execution lose all their state. Temporal solves this by making workflows durable state machines that survive process restarts, deploys, and outages. Here's what it looks like in TypeScript and Python.
P.42Most E2E test suites break as fast as the features they cover. Here's how to write Playwright tests that hold up when the UI changes, the data changes, and the team keeps shipping.
P.43Most teams treat their CI pipeline as a black box that occasionally fails. A few hours of optimization can cut your CI time by 40-60% and your GitHub Actions bill by a similar margin. Here's exactly how to do it.
P.44Rolling back a bad API endpoint takes seconds. Rolling back a bad LLM integration is harder — the damage may already be in your logs, your users' inboxes, or your clients' feeds. Feature flags are how you ship AI features without betting everything on launch day.
P.45uv is a Python package manager written in Rust that handles dependencies, virtual environments, and Python version management. We've been using it across all our projects since early 2026. Here's what actually changed.
P.46The AI IDE tools everyone uses have a feature most developers set up once and never tune: custom rules. Here's how to write rules that change how the tool generates code, not just what it says it will do.
P.47Three tools, three philosophies, three different answers to 'how should AI help me code?' We tested all three on real projects and here is the breakdown — including when to use each and when to use all three together.
