Keyboard-aware forms in React Native and Expo, with a Save button that rides the keyboard

Write Your Chrome MV3 Background Worker Like It Never Dies

How a build-time AST transform finally makes Manifest V3 state persistence painless Manifest V3 didn’t just change the extension model — it actively punishes normal JavaScript patterns. Your background service worker is…

QR Capacity Is a Mode Problem Before It Is a Size Problem

Most QR sizing arguments start with pixels. They should start with the encoder's mode choice, because the mode decides how many bits each character costs, and that decides which version the symbol needs. The generator's…

Lessons from shipping a Telegram Mini App game solo

I recently shipped a small game as a Telegram Mini App, working alone, and a few lessons stood out. Here is what I would tell myself before starting. Start the flow inside a bot. Players already live in Telegram, so the…

The maths behind an options yield matrix (and why raw premium misleads you)

A take-home test is normal. Cloning a stranger's repo and running it on your work laptop should not be. This week Binance published details of a theft it puts at around $6.3 to $6.4 billion. One step in the chain was a…

How the Text Studio Counts Words, Characters, Sentences and Bytes: 41 Probes

I work on OnePassApps, and we build the browser studios. This one is the Text Studio on app.onepassapps.com - and the part worth measuring is the row of counters that sits under the input box. Most "word counter"…

My auto-hide controls kept flickering in ArtPlayer v5: the dual-timer fight and the 1.5s immunity fix

I'm building RKMovies (a tiny 4K player for old phones) — 0.91 MB APK, hardware decode, no accounts, no tracking. The player UI runs on ArtPlayer v5, and I replaced its default controls with my own auto-hide layer. That…

Selenium Alternatives in 2026: 7 Tools Compared by What They Fix

A 4 MB JPEG occupies 46 MB of RAM: decoded image memory in the browser

A photo taken on a modern phone is about 4 MB on disk. Open it in a browser and decode it, and that same photo now occupies roughly 46 MB. That factor of twelve is the single most useful number to know when you build…

What Each OnePassApps Studio Accepts: File Types, Size Caps and Time Limits

I work on OnePassApps, so this is a note about our own product. Every limit below was read off the live app on 3 November 2026, not written from memory. Seven studios, seven different sets of limits. The caps are not…

Anonymizing FIX logs without breaking them: BodyLength, CheckSum and the five traps

Morse Code Timing: The Hidden Math Behind Dots, Dashes, and the Farnsworth Method If you've ever tried to build a Morse code feature — a translator widget, a practice app, a hardware keyer — you've discovered that the…

Tukri is a point-of-sale app for small shops in Bangladesh. Shopkeepers asked for receipts to come straight out of a cheap Bluetooth thermal printer when they tap Print, with no print window in between. This is how we…
