Code

A simple static event class that lets any deeply nested code update the main form's progressbar without passing references around.

Angular fakeAsync and tick beat setTimeout waits and jasmine.clock for time-based RxJS5 observables in unit tests.

How I use TypeScript string literals and keyof to make Immutable.js get calls type safe, so property renames break at compile time instead of runtime.

A reusable PresentableControllerMock so unit tests can dismiss modals, alerts, and toasts and assert the page callback.

Typed dev/prod config via OpaqueToken and a NODE_ENV factory so Ionic2 builds pick the right API keys at compile time.

A small Express middleware that wraps async handlers with timeout and retry for flaky database calls — cleaner than chaining promise-retry.

Use performance.mark, performance.measure, and PerformanceObserver to see how slow code actually is on users' devices — not just in the lab.

Callable Cloud Function that calls setCustomUserClaims, plus Firestore rules and client checks for a moderator claim.

Expose a raw array, wrap mutations in methods, or extend Array — three patterns for typed collections that block duplicates and invalid data.

How I migrated an Ionic Angular app with 500+ components to standalone using the official schematic, plus the routing and provider fixes that still needed a human.

Claude 3.7 Sonnet was the first time I caught myself delegating context, not lines. AI coding assistants stopped pretending to be autocomplete.

Agents fill the merge queue faster than humans can read. The constraint moved from typing to verification — and most teams still review like nothing changed.

Three years of AI-assisted development later, vibe coding is real. The thinking is yours, the judgment is yours — the typing was never the point.

AI makes junior developers look productive on week two. If we train them for speed alone, we hollow out the next decade of engineering judgment.

The single-agent model has a ceiling. Claude Code's parallel agents let you split a feature into independent pieces and work like a focused team.

How we merged three Ionic/Angular/Capacitor codebases into a single Nx workspace so a small team could stop maintaining the same code in three places.

I had stocks and ETFs across three platforms and no single place to see them. So I built one, and left it open for anyone else to use.

You cannot prompt AI-generated code into being reliable. What works is what always worked with new hires — guardrails that say no.

I stopped pointing the frontier model at my backlog and started using it to write the Skills and guidelines my cheaper models read.

My blog's CI has failed on every single push since June 20th. The site kept deploying fine the whole time, which is exactly the problem.

Living with Portfolio Ticker exposed the gaps — annualized ROI, calendar-year returns, and what happens when you sell. Here is what I added.

Harness engineering gets agents doing the work. Validation skills are what let me trust that work enough to stop watching every run.

Canon ships no Mac utility for the Canon G5040. In one session, Claude Code reverse-engineered its maintenance protocol and built me one.

Everyone says software is dead now that anyone can build their own apps. I've built over 30 of them, and that's why I don't believe it.
