A number such as “144 Hz” looks authoritative. In a browser, the important question is: what produced that number? A JavaScript animation callback, an operating-system display setting, and a physical panel measurement describe different parts of the rendering pipeline. Treating them as interchangeable produces misleading diagnostics. Disclosure: this article is published for the DisplayCheck project and was generated with AI assistance. The examples below are educational code, not a clai...

48-Hour Field Notes: I Replayed a Generated Migration Twice and the Row Counts Moved A generated backfill script looked clean in review on Monday morning, and by Wednesday it had already been applied twice against a staging copy of real shapes. The first pass rewrote 412,318 rows, and the second pass rewrote the same rows again on top of the result. Nobody had lost production data, but only because that staging database was scheduled to be destroyed that same afternoon. So I blocked two days...

Almost every production codebase is littered with comments like // TODO: handle error retry or // FIXME: memory leak under load . Over time, they become invisible noise. In TokenCap, we built src/debt/ledger.js to catalog and prioritize technical debt automatically. How the Debt Ledger Operates Tokenizer Scan: Scans source lines for standard debt prefixes ( TODO , FIXME , HACK , DEBT , OPTIMIZE ). Git Metadata Anchoring: Runs local git blame to capture the origina...

Building a Smart Task Management REST API with Node.js and Express Introduction REST APIs are an important part of modern web development because they allow applications to communicate with servers and exchange data efficiently. One practical way to understand backend development is by building a task management REST API using Node.js and Express. This project demonstrates how to organize backend functionality, manage tasks, authenticate users, and handle HTTP requests. ...

I recorded a short walkthrough of putting Nginx in front of an app and getting a free Let's Encrypt certificate onto it. Everything in the video runs on a real Ubuntu server, nothing is staged. Below are the exact commands used, so you can copy them instead of pausing the video. What you need A Linux server. I used Ubuntu 24.04 , which ships Nginx 1.24 . A domain or subdomain whose A record points at the server . If it's on Cloudflare, keep the record DNS onl...

This is a submission for the Hacktoberfest Open-Source AI Challenge Week 2: Side Hustle What I Built Korea has an IT certification called 정보관리기술사, the Professional Engineer exam in Information Management. The written part is four 100-minute sessions of handwritten essays, and you need 60 out of 100 to pass. In 2025, 1,824 people sat it and 41 passed (2.2%) . I'm a backend developer four years into my career, .NET first and Python now, and this exam is my long game. I can...

Blockchain interoperability is becoming increasingly important as businesses build applications across multiple blockchain networks. Users want to transfer digital assets, access decentralized applications, and interact with protocols without being restricted to a single ecosystem. Cross-chain bridges help connect these networks, but their architecture introduces security challenges that businesses must address from the beginning. Building reliable cross-chain bridge solutions requires more t...

Disclosure first: I built the scraper this post uses ( Threads Scraper on Apify ), so take my enthusiasm with a grain of salt. The code below is real and I ran every snippet before posting it. The outputs are what I got on October 15. Why not just use the official API? Meta does have a Threads API, but it needs a Meta developer app and an access token, and it's built mostly around your own account. If you want "the last 50 posts of some public account" or "what people posted ab...

Turn nine of a support chat feels fine. Turn ninety is a different animal. Every request resends the system prompt, three agent loops of tool noise, the user's third restatement of the same bug, and yesterday's dark-mode tangent. The model does not mind. Your invoice does — and attention quality usually dies before the hard token limit. messages.TakeLast(20) in one controller is not a policy. The second entry point forgets it. A tool-using agent keeps a function call without its result. Som...

I got tired of three things at once: the Android emulator CLI is tedious, Android Studio is a multi-gigabyte install for just running AVDs, and every decent alternative is either closed-source or expensive. So I built Enmulator — a desktop app that manages Android Virtual Devices end to end, ships on Windows/macOS/Linux, and doesn't need Android Studio installed. It's Tauri 2 on the backend (Rust, 13 modules), React 18 on the frontend, and it's GPLv3. What it actually does ...

SudokuNova is an open-source, offline-first Sudoku application built using Kotlin and Compose Multiplatform. Why this release matters Building a cross-platform applica...

Have you ever clicked a button in a React application and noticed that components you didn't touch were rendering again? Maybe a dashboard feels sluggish when updating a counter. Perhaps a large list becomes slow when typing into a search field. Or maybe you've added React. memo, useMemo, and useCallback , but the performance hasn't improved much. These problems are common in React applications, but the solution isn't to add memoization everywhere. The first step is to identify what...

At some point, a map project needs more than markers and polygons. You want something to happen on the map: water moving up a street, smoke drifting with the wind, or a shockwave spreading out from a

I'm asking this because I'm seeing some frustrating patterns and if I may be bold, I think my answer is the correct one. Here's one I'm seeing: its the SDLC agent pattern and I think its wrong. Step 1: you have good AGENTS.md documentation for your code and other principles. (this is good) Step 2: There's a somewhat strict workflow and steps enforced like planner agent, reviewer agent, critique agent and directly create a PR from a ticket. Every human intervention here is considered an anti-patt...
