React.memo Doesn't Do What You Think

What React.memo actually checks React.memo wraps a component so that, before re-rendering it, React does a shallow comparison of its new props against its previous props. If every prop is === to what it was last time, React skips re-rendering that component and reuses the previous output. "Shallow" is the key word — it compares object and function props by reference, not by deep value, ...

JVM, JRE, JDK, Bytecode & main(): 8 Questions I Had as a Beginner

Java Learning Notes — Telusko Core Java | Video 04 In the previous lesson, I finally wrote my first Java program and learned the basic: Write → Compile → Run workflow. But after writing a simple Java program, I realized that there was much more happening behind the scenes. I kept seeing terms like: Bytecode .class JVM JRE JDK main() javac WORA And I had questions like: What exactly ...

Authenticated Node.js Web Chatbot Backend Validates Streaming Reviews (Without an SDK)

Short answer: put authentication, schema validation, and stream ownership in a small backend API, and treat a code-review response as accepted only after one complete, validated findings document arrives. The browser can render provisional events, but it must not turn partial model text into e-commerce release decisions. This is a correctness choice, not an SDK preference. A signed-in web app nee...

Your Database Said "Success." Your Message Broker Said "Try Again."

This is where distributed systems get interesting. If you've worked with backend systems long enough, you've probably written code that looks roughly like this: await using var transaction = await db.Database.BeginTransactionAsync(); order.Status = OrderStatus.Paid; db.Orders.Update(order); await db.SaveChangesAsync(); await messageBus.PublishAsync( new PaymentCompleted(order.Id) ); a...

I Ran the Same Anime Character Through Meshy Multiview and Single-Image 3D

Multi-view vs single-image 3D on the same anime character in Meshy. Single-image stayed legible but flattened the relief and symmetrized the asymmetry.

I built SugarTrack: A simple offline blood sugar tracker for Android

A few weeks ago, I needed a basic way to log blood sugar readings. Most apps on the store are full of complex layouts, forced signups, cloud sync, Bluetooth setup screens, and monthly subscriptions. I just wanted a simple logbook to help me with the manual work. So I built SugarTrack. It is an Android app for recording readings from a standard glucose meter. Features Log glucose levels, time,...

Two prompts moved seven AI detectors by fifty points

The prompt was "Simplify word choices as if written by a non-native speaker." The essays were written by US eighth graders. Seven detectors had been reading that set almost perfectly, misclassifying an average of 5.19% of them as AI. After the prompt, 56.65%. Nobody changed who wrote anything. The arguments were the same arguments, by the same kids. Only the vocabulary moved. I keep meeting this...

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.

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...
