How I Built a Browser-Based PDF to Word Converter with Vue 3, pdf.js, and docx

Converting a PDF to a Word document is one of those tasks that sounds simple until you try to do it privately. Most converters upload your file to a server, process it, and send it back. That works, but it means trusting someone else with your document.I wanted a converter that runs entirely in the browser. The result is en.sotool.top/pdf-to-word/. Here's how I built it. The GoalExtract selectable text from a PDF and package it into a .docx file, without ever sending the PDF to a server.The

Why AI Hates Modern Frameworks (and Loves Web Standards)

There's a paradox nobody wants to say out loud: the same frameworks companies pick because they're "enterprise-ready," "scalable," and "industry standard" are, for an LLM writing code, a minefield.Angular, React with its whole ecosystem, Nx with its monorepos: these are powerful tools, built by humans to coordinate teams of humans on massive codebases. And for that purpose, they're often the right choice — if your primary constraint is coordinating hundreds of engineers over a decade, the conven

Building HOKMeta: static Honor of Kings data, guides, and player tools

I have been building a small site for Honor of Kings Global called HOKMeta:https://hokmeta.com/It started from a simple problem: when I looked for hero builds, counters, arcana, and item choices, a lot of content felt either too thin or too far away from how players actually make decisions before a ranked match.Most searches are not generic. Players search for very specific things:Hou Yi build 2026best arcana for Hou Yihow to counter AngelaMarco Polo build and countersbest marksman HOKSo I decid

Version history and live collaboration in a browser editor, without a server lock

Two people open the same canvas. One drags a rectangle, the other recolors a circle, both while a third person is offline on a train editing the same file. When everyone syncs, the document has to agree on one result, nobody's work can vanish, and you still want a history you can scrub back through. The lazy answer is a server lock: one editor at a time, everyone else read-only. It is easy to build and miserable to use.I want to walk through the data model that makes the hard version work, the o

Shopify vs Custom eCommerce: A Developer's Perspective on Cost and Scalability

Every Developer Has Heard This QuestionOne of the most common questions clients ask is:"Should we build a custom eCommerce platform or just use Shopify?"At first, the answer seems obvious.If the goal is to launch quickly with a limited budget, Shopify is usually the recommendation. It removes much of the complexity involved in setting up an online store, allowing businesses to focus on selling rather than managing infrastructure.On the other hand, if a project requires highly specialized f

Building a Latency-Aware Crypto Signal Bus in Node.js

Building a Latency-Aware Crypto Signal Bus in Node.jsMost crypto trading bots start as a single loop: fetch candles, calculate indicators, decide, place an order, sleep, repeat. That model is fine for a prototype, but it becomes fragile when you connect multiple exchanges, multiple strategies, account events, alerts, and risk controls. At that point the bot is no longer a loop. It is an event system.A signal bus is the internal layer that moves information between those parts. It receives

I cataloged 93 CJK and Unicode bugs in open source. Most are the same five mistakes.

I keep a Japanese keyboard on while reading other people's code. Not for any noble reason at first, it's just my keyboard. But after a while you start seeing the same small breakages over and over, in libraries that are otherwise excellent and work perfectly in English. So I started writing them down. The list is now 93 entries across 87 libraries, and it's public:https://greymoth-jp.github.io/cjk-failure-corpusIt's built like caniuse, except instead of "does this browser support X" it's "here i
