Stop Writing Auth Logic Twice: Automate API Authentication with Pre-Processors
Every developer has been there. You're testing an API that requires HMAC-signed requests. So you open your terminal, hash the payload manually, paste the signature into the header field, hit send — and it expired 30 seconds ago. You do it again.Authentication is the most repeated, most error-prone part of API testing. And it doesn't have to be.This post walks through how pre-processors can eliminate the manual auth dance entirely — so your requests just work, every time you hit send. What I
Timers in React Without setTimeout: useTimeout, useInterval, useCountDown, and useRafFn
Timers in React Without setTimeout: useTimeout, useInterval, useCountDown, and useRafFnTimers are one of those things every React developer writes by hand the first ten times and gets wrong on at least six of them. The pattern looks simple: call setTimeout in a useEffect, return a cleanup function, ship it. Then a code review finds the stale closure. Then a bug ticket arrives because the delay is being read from props at mount instead of from the current render. Then someone notices the in
Promise Combinators: race, allSettled, any
Promise Combinators: race, allSettled, anyJavaScript, as a language designed for asynchronous programming, has embraced promises as a central model in handling asynchronous operations. Among the foundational promise methods, Promise.race, Promise.allSettled, and Promise.any serve as powerful combinators—tools that manipulate and combine multiple Promise objects. This exhaustive guide will explore the historical context, technical nuances, practical applications, edge cases, performance con
A Browser-Only Diary in 350 Lines — Month-Grid Math, Code-Point Character Counts, and Streak Boundaries
A journaling app is one of the rare cases where the server side adds nothing: only the writer reads it, search load is tiny, no images required and 5 MB of localStorage covers decades. This is the 350-line browser-only diary that ended up working — a month calendar with click-to-pick, a textarea that saves on a 280 ms debounce, and a stat row showing streak + character count. The interesting parts are the 6×7 month grid math, code-point character counting for CJK + emoji, and the boundary condit
Simplify setTimeout
Hidden in plain sight is a functional programming interface you may have never used, and understanding it can change the way you code. It also fixes a classic JavaScript "gotcha"!setTimeout is a staple of example code. When simulating asynchronous actions for demos, setTimeout is the go-to function. But there's always a bit of anonymous function boilerplate in the examples. Classic setTimeoutYou've probably seen examples like these many times:const aPromise = new Promise((resolve, reject) =

In the practical sense.We install a package, which installs other packages, which wrap lower-level packages, which hide runtime behavior behind conventions, build steps, plugins, adapters, loaders, and generated code.

Why I built Inktag — a `<img>`-shaped tag that locks AI images to your brand
The moment I gave up on stock photosIn January I pulled my image invoices for the prior year. Shutterstock, Unsplash+, the occasional Getty one-off.$387. For pictures of "diverse team smiling at laptop" and "hands typing on MacBook keyboard."The thing that bugged me wasn't the money. It was that my blog looked like every other blog on the internet using the same three stock sites. I'd written 40-something posts that year and not one of them looked like mine.So I switched to AI image gen fo
Learning Progress Pt.11
Daily learning part elevenToday I started at 12:30 with the 350 pages of reading and finished the entire book at 17:30. During that time I also reviewed my history lessons.I started my daily cybersecurity grind at 17:50. First I did the JS debugging section—I’m almost at the end of the course. I also wrote two scripts: one in JavaScript and one in Python. Yesterday I made an IP address extractor and a hostname extractor, so I figured why not combine both. I did it first in JavaScript, which was

Four user roles. One payment gateway that lied to me. Three rewrites of the same feature. And a GPS bug that nearly flooded my database. This is the real story behind Savor. I was tired of building things that felt fakeAt some point every developer hits a wall with tutorial projects. You've built the weather app. You've done the blog CRUD. You've cloned Twitter in a weekend. And none of it actually teaches you what it feels like when four different types of users are all touching the same d
Macchiato Day 1: The Agentic Terminal Born from a Coffee Cup
Series: Macchiato's LogToday I didn't drink coffee. I drank Macchiato.I have four projects open right now. Vue, Spring Boot, a Node worker, the Guayoyo landing page. Each uses Claude Code or OpenCode depending on the day, the mood, or whichever CLI didn't break that week.The ritual is always the same: cd ~/projects/whatever, which claude — nope, it was OpenCode — and by the time the CLI launches I've already lost my train of thought.The friction isn't in using the AI. It's in getting to use it.
