Solon Multi-Environment Config: Six Loading Tiers, an In-File Segment Trick, and No Profiles API

If you've spent time with Spring Boot, you know the spring.profiles.active routine — one property, multiple application-{profile}.properties files, and a creeping suspicion that somewhere a prod config is silently falling back to dev defaults. Solon's answer is solon.env. Same concept, different design choices — and one pattern (solon.env.on in-file segments) that Spring has no direct equivalent ...

Gemini Spark Brings Voice Dictation and In-Place Rewriting to the Mac Desktop

Google is expanding its native Gemini for Mac app with Gemini Spark, a desktop AI experience that brings voice-driven drafting and in-place text rewriting into the user's active workflow. The most consequential change is practical rather than cosmetic: users can dictate, draft or rewrite copy directly at the cursor in any window, with Gemini using context from the screen to turn spoken input into ...

Stop Re-Explaining Yourself to Claude: Structure a Project That Remembers Your Work

Every new chat makes Claude a stranger again You explain the codebase. You paste the style guide. You re-describe the client, the constraints, the one legacy decision you have to live with. Then the chat gets long, you start a fresh one, and you do it all again. That re-briefing tax is a big part of why AI assistants still feel like a demo instead of a coworker. Claude Projects exist t...

What a Portal's Resize Pipeline Actually Does to a Real Estate Listing Photo

A listing photo leaves the camera looking right. By the time a portal has resized it for a thumbnail grid and recompressed it for delivery, it can look flatter, softer, or faintly wrong in a way nobody can quite name. None of that requires a bug on anyone's part — every step is documented, default behaviour in the image libraries doing the work. We build CasaNova Labs, an AI studio for real estat...

[AskJS] Ottimizzazione dynamic img rendering in JS: Eager/Lazy + contentVisibility. Voi come gestite il primo fold?

Ciao a tutti! Sto ottimizzando il caricamento dinamico delle immagini per le schede dei giochi. Sto usando questa logica per bilanciare il caricamento immediato sopra la piega (above the fold) e il caricamento "lazy" per il resto: const img = document.createElement('img'); img.alt = (gioco.titolo || 'Gioco'); img.decoding = 'async'; img.style.contentVisibility = 'auto'; img.style.width =...

How to Build a Customized Chat UI for n8n Chat Webhooks?

n8n's Chat Trigger node gives you a webhook that accepts a message and returns a reply. It does not give you a UI. If you're embedding that workflow on a real product, "reply in JSON" isn't good enough. You need a chat window that matches your brand, handles sessions, and doesn't leak your webhook URL to every visitor who opens dev tools. Here's how to actually build that, and where most tutorial...

React Mastery Series – Day 7: State in React – Making Components Dynamic

Welcome back to the React Mastery Series! In the previous article, we explored Props, which allow parent components to pass data to child components. But what happens when the data needs to change over time? Think about applications you use every day: A shopping cart where items are added or removed. A banking app where the account balance updates after a transaction. A social media app where...

Writing Agent Memories: What to Store and What to Skip

Not everything an agent sees is worth remembering. Store too little and it forgets what mattered; store everything and the memory fills with noise that drowns the signal at retrieval time. The extraction step — deciding what to keep and distilling it into clean, self-contained facts — is the most consequential and most overlooked part of a memory system. Memory begins with a decision ...

I built an open, reproducible typing-speed test — and it won't show a number until it earns one

Search "average typing speed" and you'll get confident numbers — 40 WPM, 65 WPM, "professionals hit 75" — almost always with no passage, no method, and no dataset behind them. I wanted one I could actually defend, so I built a live typing test that collects an open, anonymized dataset and, crucially, refuses to publish an average until it has enough data to mean anything. It runs on Cloudflare Wo...

Learning to Code When AI Writes the Code

It works and I don't know why. That is the most dangerous sentence I can say about my own code, and it got very easy to say. I started writing software in 2025, the year AI got good enough to write most of it for me. I have never learned to code without it. Most of what I read about this is written by people who learned first and got the tool second. For them AI removed a toll booth: they alread...

Most Developer Profiles Break the Moment You Ask for Proof

A few months ago, I started looking at developer profiles the way a reviewer looks at production logs. Not the polished summary, not the clean headline, not the list of tools. I wanted to know what could actually be verified. That is where things got uncomfortable. A lot of profiles look strong until you ask one simple question: which parts can be checked without trusting the person who wrote them...
