-- title: "Parsing tweets.js Without the Encoding Headaches" description: "The X archive file is JavaScript with a JSON array inside it. Strip the wrapper, then deal with the layer that actually breaks things: code…
Disclosure first I built FocusDash and I sell it for $5, so this is not a neutral post about someone else's product. It is a walk-through of my own code, written so you can check me instead of believing me. "No data…
Our free translator ran a small machine-translation model directly in the browser (a Bergamot / Opus-MT style model compiled to WebAssembly). The appeal is privacy: the text never leaves the device. The downside is…
I run a photo enhancer that does super-resolution fully in the browser: TensorFlow.js on WebGL, nothing is uploaded. The first version used the upscaler library (UpscalerJS). On a 1.2 megapixel photo it took 60-110…
북마크를 공유할 때는 대개 제목과 분류부터 정리합니다. 그런데 공개할 링크를 고르기 전에 한 가지 질문이 더 필요합니다. 이 주소를 처음 보는 사람에게 그대로 보여줘도 될까? 예를 들어 도움말 페이지와 개인 주문 내역은 같은 서비스 안에 있어도 공개 범위가 다릅니다. 화면 제목이 평범하다는 이유로 주소까지 평범한 것은 아닙니다. 검색창에 입력한 내용이 주소에 남거나, 특정 문서를 여는…
Your teammate starts the hackathon backend and gets an authentication error several minutes later. A required environment variable was empty. Check required configuration when the server starts, report the missing names…
Your hackathon dashboard displays 0% when the API has not supplied a reading. The screen looks complete, but it now says something the data never said. Keep a real zero visible and label a missing reading as missing.…
Government photo upload forms are strict about file size, and they are strict in both directions. The US DS-160 visa form wants a JPEG of at most 240 KB with a compression ratio no higher than 20:1. China's online visa…
Objects are collections of key-value pairs An object stores data as properties, where each property has a key (string or Symbol) and a corresponding value (any data type, including other objects or functions). Objects…
Why Multilingual Voice Matters in 2024 If you’ve ever built an app that reaches users beyond your native tongue, you know the pain of juggling separate audio pipelines for each language. Subtitles are a quick fix, but…
Hello DEV Community 👋🏽💻 I’m a Software Engineering graduate and a developer currently growing my skills in web development. I’ve been working with technologies like JavaScript, React, HTML, CSS, Python and SQL, and I’m…
Auto-highlights sound like a shortcut. Sometimes they are. But selecting a clip is not the same as understanding why a moment matters. A useful short often depends on context: the sentence before the punchline, the…
This one covers five days, September 25 to 29. Most of it went into rules for the tools I build with: a CLI that reports before it acts, and a workflow kit that split every file over 500 lines. The rest went into a new…
Angular apps don't go slow because Angular is slow. They go slow because the defaults — Default change detection, NgModules with eager imports, no trackBy, BehaviorSubject everywhere, no lazy loading — were designed for…
I was building a desktop viewer for JSON, CSV and Markdown files, and I wanted it to handle a genuinely large CSV: a million rows, 55 MB, the kind of export an eval run spits out. Loading was fine. Scrolling was fine.…
Java vs. JavaScript: What Every CS Student Should Know If you are a Computer Science student, you have probably heard about Java and JavaScript. Their names look similar, but they are actually two different programming…
If you already have a folder of clips, the CapCut-versus-Opus Clip question is often framed backwards. CapCut and Opus Clip are useful, but they solve different problems: CapCut is a broad editor. It is a good fit when…
It does not generate a video from a prompt, auto-pick highlights, add captions or music, or promise reach. Editing and preview are free. Finished MP4 export is on the Starter plan at $19.99/month. That boundary is…
Government photo rules read like a spec sheet. The DS-160 (US visa) wants a square JPEG between 600×600 and 1200×1200 px, at most 240 KB, with the head (chin to top of hair) taking 50–69% of the image height and the…
The favicon tool in an image editor I run used to write every entry in its favicon.ico as a PNG. Browsers are fine with that. Then I loaded the file with System.Drawing from Windows PowerShell, and it threw: Exception…
