Password Recovery Messaging: Localized HTML Previews Through a Transactional API

A healthtech marketplace has two messages that look similar in a delivery dashboard but are not operationally equivalent: a password reset email controls access to an account, while a new-order email tells a seller that work is waiting. The best template approach keeps localized HTML copy and preview outside the application release without surrendering security logic to the email API. Short answe...

Building a Two-Stage Voice Recorder with Transcription

When people say they want real-time transcription, they often mean two different things: words should appear quickly, and the final note should be easy to use.\n\nA practical voice recorder with transcription can treat those as separate stages.\n\n## Stage one: fast, honest text\n\nThe live view should show partial speech quickly, while making it clear that the text is provisional. Short audio chu...

Writing Your First Java Code: 5 Questions I Had as a Beginner

Java Learning Notes — Telusko Core Java | Video 03 After installing the JDK and setting up VS Code, I finally reached the part I was waiting for: Writing my first Java code. At this point, I thought the process would be very simple: Open VS Code → write System.out.println() → run it. But while going through the lesson, I realized that there are a few things I need to understand before a...

Shadow Traffic Is the Only Honest Free Model Evaluation

The demo replay played in the dim glow of a conference room, and everyone agreed the free model sounded good. The same four prompts produced crisp summaries, polite error handling, and no obvious hallucination, so the conversation drifted toward replacing our paid endpoint before lunch. I sat through it with an uncomfortable question that nobody asked: why were we trusting a handful of canned exam...

Is playwright being used efficiently for test automation?

I’ve been exploring Playwright for test automation and one thing I’ve been thinking about is how efficiently teams are actually using it beyond simply automating test cases. Playwright provides features such as auto-waiting, web-first assertions, parallel execution, browser contexts, network interception, tracing, and built-in test isolation. But having access to these features doesn’t necessarily...

From HTTP Requests to Atomic On-Chain Transactions

Coming from Web2, I initially thought of a Solana transaction like an API request: send request -> server processes it -> get response But after working with Solana transactions, I realized the mental model is quite different. A Solana transaction is a package containing things like signatures, instructions, accounts, and a recent blockhash. The transaction is signed before it can be acc...

20 Native macOS Apps That Replaced My Electron Bloat for Good

I opened Activity Monitor last year on a Thursday afternoon, just to check something quick. Slack was sitting at 780MB. Discord was at 410MB. Notion was at 490MB. Spotify was lurking at 280MB. I had four apps open — and they'd already consumed nearly 2GB of RAM before I'd written a single line of code. My MacBook Pro fan was humming like it was rendering a film. The battery had dropped 18% in und...

How to Add a Command Menu to a Telegram Bot with Python

A Telegram bot can recognize commands without displaying them in the client. However, users should not have to memorize every available command. Registering a command menu lets Telegram show a list when someone taps the menu button or types /. In this tutorial, we will create /start, /help, and /status handlers, register them through the Bot API, and display different command menus in private cha...

How to Stop AI Hallucinations: 6 Prompt Tactics That Reduce Made-Up Answers

AI hallucinations are a structural problem, not a bug you can patch. But you can reduce their frequency and make the ones that slip through much easier to catch — using specific prompt tactics that cost almost nothing to apply. Here are 6 that work. Why AI Makes Things Up Large language models don't "know" facts the way a database does. They predict the next most-plausible token ba...

What I Learned Turning a Side Project Into a Sellable Dev Tool

I built Materia AI to solve a real problem I saw firsthand — messy menu and inventory management from my years working as a waiter. It's still growing. But somewhere along the way, I realized the backend pattern I kept reusing — the FastAPI structure, the AI service layer — was useful on its own, separate from the specific product. So I pulled it out and packaged it. Here's what that process actu...

Real Ephemeris Math, Graceful AI Degradation, and a Rebuild Gotcha: Building an Astrology SaaS on Cloudflare Workers

Most "astrology app" tech stacks are a sun-sign lookup table and a template string. I've spent the last few months building AstroMystra, a Next.js app that does actual ephemeris calculations for Vedic (sidereal) and Western (tropical) charts, generates AI-written readings from those calculations, and — as of a few weeks ago — runs entirely on Cloudflare Workers instead of Vercel.

Building a GraphQL Video Discovery API with Strawberry and FastAPI over SQLite

Our Android client painted one search screen with four HTTP requests: GET /api/search?q=, then GET /api/channels?ids=, then GET /api/categories, then a per-video GET /api/video/{id} as soon as the user tapped a card. Every one of those endpoints returned the whole row out of SQLite — 41 columns for a video — and the client rendered six of them. On a throttled 3G profile the screen took 2.4 s at p9...
