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

Cracking the Firefox Performance Puzzle for "Moksha"Hey everyone! As I’ve been testing Moksha—our vanilla JS and HTML5 Canvas game—across different browsers, I ran into a massive roadblock: Firefox was lagging heavily, while Chromium-based browsers like Chrome ran smoothly at a solid 60+ FPS. Because Moksha uses a raw 2D canvas context without a heavyweight game engine, it relies completely on the browser's native rendering efficiency. Here is a breakdown of why this lag happens in Firefox

I said my tool supported multiple instances. A stranger running 15 of them filed three bugs. All three were right.

I maintain safari-mcp, an MCP server that lets AI agents drive a real Safari session on macOS. Over a few releases this summer I shipped per-session tab isolation — the feature that lets several agents share one browser without stealing each other's tabs. I wrote about it here. Twice. I was reasonably proud of it.Then a stranger showed up with a deployment I had never imagined — three macOS profiles, up to fifteen concurrent server instances — and filed three bug reports in the space of seven se

What I Learned While Testing OllaNode’s Free Version With Node.js

I usually prefer testing the service myself before coming to any conclusion about its usefulness for my purposes. In this regard, I have recently started using OllaNode because I wanted to find a convenient way to test my node.js applications outside of my local environment. Besides, I have been using the free version of the service for experimentation and lightweight project deployments anyway, so there is not much to lose from the potential transition to a paid plan.The most pleasant surprise

How I structure React Next.js patterns across every client project

Every new Next.js project I start has the same skeleton. Not because I copy-paste a boilerplate, but because I've converged on a set of React Next.js patterns that solve the same class of problems every time — server-first rendering, predictable data flow, typed boundaries, and consistent error handling. This post documents those patterns so I can point clients and collaborators at something concrete. Server components by default, client components by exceptionThe App Router made server com

Solving Hydration Failures and Tree-Shaking in React: Announcing react-hook-lab v1.13.0

If you have ever built a server-rendered React application (using Next.js or Remix), you know the nightmare of client-server hydration mismatch errors. One of the most common offenders is state synchronization with browser storage—especially cookies.Today, we are excited to release react-hook-lab v1.13.0, which addresses this exact headache. This update introduces the brand new useCookie hook, standardizes our asynchronous useResource module, and completely overhauls our library's export structu

I got tired of console.log debugging, so I built DevTools for my backend

You know the dance.An endpoint is slow. So you open the handler and start sprinkling:console.log("got here");console.log("query done", Date.now() - t0);console.log("still here??");Then you squint at tail -f, mentally stitch the lines back into an order,and try to remember which log came from which request, because three of themare interleaved.I did this for years. Then one day it hit me that the frontend solved thisfifteen years ago. You open DevTools, you get a Network tab, and you justsee it.

I Tried an AI Tool That Turns a Prompt Into a Real Mobile App

Building a mobile app used to mean learning a programming language, setting up a development environment, and figuring out how to get everything working together. AI app builders are starting to change that.One tool I recently came across is RapidNative. It lets you describe the mobile app you want in plain English and uses AI to generate a React Native app.What caught my attention is that it focuses on actual mobile apps rather than just website mockups. According to RapidNative, you can start

React useElementSize Hook: Track Element Width & Height with ResizeObserver (2026)

Media queries answer one question: how big is the viewport? But your components don't live in the viewport — they live in columns, cards, panels, and grid tracks. The same <ProductCard> is 900px wide in a full-width main column and 320px wide next to an open sidebar, on the same screen. And an element's size changes for a dozen reasons that never fire a window resize event: a sidebar collapses, an accordion expands, a font finishes loading, a flex sibling appears, content streams in.Tracki
