Build a .gitignore Engine in JavaScript: Last-Match-Wins, Path-Aware Globs, and the Parent Directory Trap

Almost everyone reads a .gitignore top to bottom like a shopping list and assumes the first rule that matches decides. It is the opposite. Git evaluates every line and keeps the last one that matched, and that one decides.That single choice is the whole reason ! negation can exist. If the first match won, a ! could never override anything written above it.Then a second rule quietly overrides the first: git does not test paths against patterns, it walks directories, and it never walks into a dire

An Emoji Is Not a Character, and an Emoji Picker Is Not a Grid of Buttons

Everybody builds the emoji picker the same way. A grid of buttons, a text input, and list.filter(e => e.name.includes(query)). It looks finished in an afternoon and it is wrong in three directions: wrong about ranking, because includes has no opinion about which match is better; wrong about drawing, because hundreds of live buttons mean a layout pass you pay for on every scroll; and wrong about text, because the thing you are inserting is not a character — it is up to eleven UTF-16 code units

SET Is Not a Card Game, It Is Four-Dimensional Arithmetic Wearing a Deck of 81 Cards

SET is the little deck with the coloured squiggles: eighty-one cards, four attributes, and one rule that everybody learns as two rules. Deal twelve cards, find three where each attribute is all the same or all different, shout, take them, refill.I rebuilt it in vanilla JavaScript with real inline SVG cards, and the whole thing turned out to be a lesson in choosing a representation. Get that one decision right and the rule collapses to a modular sum, the third card of any pair becomes a subtracti

React Native vs Flutter in 2026: Which One Should You Choose?

Your Three.js scene is leaking, and removing the mesh didn't help

The symptom is unmistakable once you've seen it: navigate between two views a dozen times and the tab climbs past a gigabyte, or the frame rate degrades and never recovers.scene.remove(mesh)mesh = nullBoth lines run. Memory doesn't come back. What remove does and doesn't doscene.remove() detaches the object from the scene graph. That's all it does. JavaScript will happily collect the Mesh object itself.But a Mesh is a thin wrapper. The actual data — vertex buffers, index buffers, texture up

Understanding API Fetching: What Developers Should Know About "Crackers"

When working with APIs, it's important to understand the difference between normal API consumption and unauthorized access.A typical application might fetch data from an API like this:fetch("https://api.example.com/data", { headers: { "Authorization": "Bearer YOUR_TOKEN" }}) .then(response => response.json()) .then(data => console.log(data));The important part is that the server controls access. The frontend can request data, but the API should verify authentication and authorizatio

AlgoVerse: watching algorithms think at 60fps in the browser

Algorithms you can watch thinkA sorting algorithm is a set of decisions unfolding over time. A textbook flattens that into pseudocode and a Big-O label, and something is lost — you can memorize that quicksort is O(n log n) on average without ever seeing why it degrades on a sorted array. AlgoVerse is my attempt to put the time dimension back: a client-side platform where you watch data structures and algorithms actually run, step by step, at 60fps.There's a live demo, and the whole thing r

Guilded-Guild: recommending the next item with SASRec in PyTorch

Recommending the next thing, not a similar thingClassical recommenders treat your history as a bag of items: you liked these ten movies, here are ten more that people with similar bags also liked. That works, but it throws away the single most informative signal you have — order. What you watched last says more about what you want next than what you watched a year ago.Guilded-Guild is a recommendation engine built around that idea. It models the sequence of a user's interactions with a sel

Building Netra: an edge-AI camera that tracks you on its own

A camera that decides where to lookMost hobby surveillance projects stop at "stream a webcam to a browser." Netra doesn't. It's a closed-loop system: an ESP32-CAM streams frames, a YOLOv8 model finds the person in them, and the result drives two servos that physically turn the camera to keep that person centered — all coordinated over MQTT. The name comes from the Sanskrit word for eye, and that's the honest description of what it is: an eye that moves on its own.It started as a Microproce

New EU Guidelines For AI Labelling

There’s been a lot of confusion and panic this week about “huge fines”, “drastic measures” and “sweeping new AI rules” in the EU. In reality, it’s a lot more narrow — and a lot more sensible. And mostly it’s about making AI more obvious when it actually needs to be obvious — especially for AI-generated content.Starting from Aug 2, 2026, AI labelling is a legal requirement for any company that serves EU citizens. And similar to European Accessibility Act, it’s not limited to EU companies. It affe
