Making a screenshot PDF searchable — no OCR, because we rendered the page

We archive whole web pages as PDFs. Under the hood each page is a full-height screenshot dropped onto a PDF page — which looks perfect and is completely useless the moment you want to use the text. Ctrl+F finds nothing. You can't copy a sentence. A screen reader opens the document and sees… an empty page with one big image. The fix is the same trick a "searchable scan" uses: draw the real text in...

I built a Markdown editor under 10MB because Obsidian felt too heavy

I love writing in Markdown. What I don't love is opening a 200MB+ Electron app just to jot down a note. So I built Markify - a desktop Markdown editor that weighs in at under 10MB and still ships a real feature set. Why bother Obsidian is great, but it's heavy, and most of what I actually need day-to-day is simpler: open a file, write, preview, export, done. Every "lightweight" alterna...

Pi4J LED Playground: A Community Resource for Learning Hardware Programming with Java

One of the best moments when learning electronics is seeing your first LED blink. It's a simple experiment, but it represents the bridge between software and the physical world. With Java and Pi4J, that first step is already well documented. But what happens after the first LED? How do you experiment with different animations, colours, brightness levels, or GPIO configurations without repeatedly ...

Chapter 2 (Part 2) Knowledge Retrieval Engine

2.6 Why Retrieval Is Necessary A Large Language Model only knows what was available during its training. If the user asks about something that changed after the model was trained, the model may not know the latest information. Instead of forcing the language model to guess, ACAI first determines whether external information is required. User Prompt │ ▼ Need External Knowledge? ...

A benchmark is only as good as the model you use to grade it

I built a pytest harness that runs the same set of questions through five language models at once - a free local Llama, plus GPT, DeepSeek, and two Claude models - and compares them on the three things a team pays for: cost per query, speed, and answer quality. The plan was simple. Run the grid, read the scoreboard, say which model to use. The scoreboard came back clean and easy to read. This is ...

How to Convert PDF to Word in the Browser with Vue 3 and pdf-lib

Converting PDF to Word seems straightforward, but the reality is more complex. PDF stores text as character coordinates, while Word uses structured paragraphs. Bridging this gap requires careful text extraction and order reconstruction. Here's how to build a browser-based PDF to Word converter with Vue 3 and pdf-lib. The challenge: PDF vs Word PDF is a presentation format — text is po...

Trust Scores for Agents: How a Trust Rating Actually Gets Computed

Trust Scores for Agents: How a Trust Rating Actually Gets Computed When a human applies for a mortgage, their credit score is a summary of their financial past — how reliably they paid debts, how much they owe, how long they've been borrowing. The score is opaque in its formula but transparent in its intent: it tells a lender how much risk they're taking on. Agent reputation systems fac...

I got tired of writing boilerplate imports, so I built Block: Run Python, JS, and Lua in a single file

💡 The Problem: The Import / Glue Code Headache A while ago, I was practicing importing modules across different projects. I wanted to use Python for its rich data science libraries and Node.js for its async web performance. Normally, if you want Python to pass a simple calculated array or dictionary to JavaScript, you have to: Spin up a local FastAPI / Flask server or write to a temp...

I sorted music for a living. Sometimes ten seconds was enough

Then I'd sit down to my own work and lose fifteen minutes choosing a track. For about three years I worked for a stock music library, and most of the job wasn't what people assume. I found the artists myself, solo performers and small bands, then explained how the library and licensing worked. The ones who said yes sent me their catalogues. I uploaded the files and started listening. That's whe...

Before You Add Kafka, Redis, and Elasticsearch: Try One Postgres First

Last month I was building out my own AI agent infrastructure, the side project where I run a few agents that research, draft, and publish content. The agents needed three things beyond the main database: a job queue, a cache for repeated lookups, and search over article text. My instinct, six years of Spring Boot muscle memory, was to reach for the usual stack. RabbitMQ or Redis Streams for the qu...
