🐍 Fixing a `google-genai` Version Mismatch and Verifying the Behavior with pytest [1/3]

Introduction Hello from Japan! 🇯🇵 I am tosane932, a professional truck driver working in logistics while teaching myself Python. In my previous article, I tested a Docker multi-stage build and measured the actual change in image size. At the end of that article, I said that I would write next about pytest and CI/CD. This article was supposed to be the practical follow-up. However, ...

Why My Expo Router App Froze on the Splash Screen After a Cold-Start Notification Tap

This is an English translation of my original article on Qiita. My Expo app occasionally stayed on the splash screen when it was launched by tapping a push notification from a terminated state. Opening the app normally worked. Tapping a notification after the app had already started also worked. The splash screen was not the cause. Two navigation operations were competing during startup. ...

I Rewrote My Resume Once and Stopped Getting Ghosted. Then Oracle Called

For months, my resume was a list of things I had touched. React. Java. SQL. Docker. All true, all useless. I sent it out. Nothing came back. Not rejections — silence, which is worse, because a rejection at least tells you someone read the thing. Then I rewrote it. Same person, same internship, same side project, same six months of work. The second version got interviews, and eventually the offer...

I used the Hacker News API to check 5,000 old links. 34 domains are now unregistered.

Hacker News never rechecks a link. A story submitted in 2012 keeps its points, its comment thread and its URL forever. The site will happily send you to that URL in 2026 whether or not anything is still there. I wanted a base rate for that, specifically for HN rather than for the web in general, so I wrote a checker and pointed it at the archive. The numbers below are what it produced. ...

Spaced Repetition Under the Hood: How We Decide When to Show a Word Again

Disclosure: I build VibeLing, a vocabulary app. This post is about the scheduler inside it — what it does, what we deliberately didn't build, and the thing that broke once real people started using it. Every spaced repetition app has one function at its core: given a word and everything that has happened to it so far, return a date. Show it again on that date. Everything else — the card UI, the a...

Shopify's Open Secret: Every Store Exposes /products.json Build in public: how I turned a 10-line trick into a working Shopify scraper — no login, no CAPTCHA, no anti-bot. If you've ever tried scraping an e-commerce site, you know the drill: Cloudflare walls, CAPTCHAs, session tokens, cat-and-mouse games with anti-bot teams. Then I discovered that most Shopify stores hand you their...

Five AI Models Independently Picked the Same Crypto. The Fact-Check Didn't Agree With All of Them.

Written by Marlowe Finch, archival bloodhound at Bitcoin Institute, an archive of Bitcoin's primary sources. Five AI products from five different labs. One question, asked once each, same wording, no coordination between runs, framed explicitly as a research question rather than financial advice: if you had to invest in exactly one cryptocurrency, which one, and why. Nobody hedged. Nobody named t...

How I Ran Custom Model Providers in Separate Codex Desktop Apps

After building Toolboard, I started exploring a different kind of product problem: how to use a custom model provider inside Codex Desktop without turning the main installation into an experimental environment. The obvious approach was to edit the existing configuration and point it at another endpoint. I did not want to do that. My normal Codex setup already had its own sessions, configuration...

Sprite Sheets 101: A Practical Guide for Indie 2D Game Devs

Picture this: your 2D game started clean, a few sprites here and there. Fast forward a few months and you've got a folder with 200+ individual PNGs, load times are dragging, and animations are choppy. Sound familiar? There's a decades-old fix for this, and it's still the industry standard in 2026: sprite sheets. Instead of loading a separate file for every frame, tile, or UI element, you pack th...

When is an AI agent the right call vs hardcoding the rules?

I work in a big old enterprise. Decades of writing deterministic code for every niche workflow has left us with brittle siloed systems, poor data quality, stale documentation, and endless maintenance. We're so slow that business users route around us with low-code tools and there are now hundreds of unmanaged workflows. Management mandated we start building agents into our systems to resolve some ...
