Flutter freezed + json_serializable — When to Use Auto-Generated fromJson and When Not To

Why I Added freezed to My Flutter App — Unifying Model Patterns Why I did it My solo app Book Log has 4 entity models: AuthUser, Book, BookSearchResult, Sentence. Each had a different style of fromJson — some had copyWith and some didn't. No consistent pattern. Inconsistent model classes can lead to unexpected bugs. I wanted every model to follow the same structure. With fre...

We Built 118 MCP Tools. Here's What AI Actually Does With Them

A couple of months ago we finished exposing our SaaS through an MCP server. It now has 118 tools across 12 domains. I want to show what an AI actually does with all of that, because it's not really what we designed for. PaperLink is a document-sharing and accounting SaaS. You connect Claude, ChatGPT, or any MCP client with one command and start talking to your data. Five examples from real conver...

Microsoft Power BI is one of the most widely used business intelligence tools available today. Organizations rely on it to analyze data, monitor performance, and build interactive dashboards that turn raw numbers into actionable insights. Rather than working with static spreadsheets, analysts can connect Power BI to live data sources — ensuring reports stay accurate and up to date in real time. S...

AI security is now a token-burning contest. Who's watching the bill?

AI security is now a token-burning contest. Who's watching the bill? Simon Willison just reframed AI-assisted security research as proof of work: throw more tokens at the problem, get better results. That's an economic reality, not a metaphor. If your security team is running Claude Mythos and similar tools at scale, you are now in a compute-spend arms race. Someone needs to be watching...

Small Publishers Lost 60% of Google Traffic. Here

In September 2023, Google rolled out what they called the "Helpful Content Update." For a lot of small publishers and independent content sites, it was more like a death sentence. Sites that had been getting 50,000-100,000 monthly visits from Google woke up to 5,000-10,000. Some dropped even further. A publisher I know went from 80,000 monthly organic visits to under 12,000. Overnight. The forum...

5 Wikipedia Tables That Break Most Scrapers (And How to Fix Them)

Wikipedia is the most common source for web table data. It's also a minefield of edge cases that break naive scrapers. I've collected the five patterns that cause the most issues while building HTML Table Exporter, with detection code and fixes for each. Pattern 1: Navigation Rows ("v t e") The Problem: <table> <tr> <td colspan="5">v t e Countries by populat...

Where to Start with React Performance

You've probably already tried something. Added useMemo in a few places. Run Lighthouse. Checked the bundle size. Maybe split a route or two. And the app still feels slow. The issue is usually not the optimization — it's that the mental model came later, or never. Performance work done without a clear picture of what you're measuring is mostly guesswork. Some of it sticks. A lot doesn't. The art...

How to Teach the LLM to Think With Your Data

This approach misses the real strength of LLMs. Instead of exposing raw RAG output, we should feed the retrieval knowledge back into the LLM first. This allows the model to reason with the context, synthesize multiple pieces of information, and deliver answers that are more accurate, natural, and aligned with user intent. In other words, we are not just teaching the LLM facts - we're teaching it t...

When System Prompts Become Prompt Debt -What GitHub Copilot’s hidden instructions reveal about AI agent design

I Read the System Prompt Most discussions about coding agents focus on model quality. I decided to inspect something else: the system prompt. What I found was not a short hidden prompt, but a large prompt program implemented in TypeScript (AgentPrompt.tsx), with conditional rendering, tool routing, memory instructions, safety rules, behavioral policies, and identity constraints. It ...

KYC vs ID verification: the same software, for different reasons

The first time I watched the compliance team and the fraud team at the same company argue over which vendor to pick, I thought they were arguing about the wrong thing. They agreed on the shortlist. They’d sat through the demos together. What they couldn’t agree on was what the product was for. KYC software and ID verification software look identical from the outside. They check a document. They c...

OCR Is Not Redaction: Building Safer Auto-Redaction With Tesseract.js

OCR demos usually stop too early. They show recognize(), print some text, and imply that automatic redaction is basically done. In a real product, that is maybe 20 percent of the job. What users actually need is a safer pipeline: Run OCR on the image. Classify risky spans such as emails, phone numbers, account references, dates, and IDs. Map those matched spans back to OCR word boxes. Pad the ...

Why Your AI Agent Forgets Everything When You Close the Tab

I spent months re-explaining myself to an AI that couldn't remember me. Every session: who I am, what I'm building, what the voice sounds like, what the customer context is, where the project stands. Paste it in, do the work, close the tab. Open a new one. Start over. Waxell Connect solves this by giving AI agents a persistent place to work between sessions. A workspace in Connect contains everyt...

Why We Split meta/root and coordinator in NoKV

Links Repo: https://github.com/feichai0017/NoKV Interactive demo: https://demo.eric-sgc.cafe/ When people first look at a distributed KV system, one of the most natural assumptions is: “There should be one control-plane service that owns the cluster metadata.” That intuition is understandable.

I built the "Premium" Admin Template I couldn't find for free (Next.js + Tailwind) 🚀

I have a confession: I’m a developer who is obsessed with aesthetics. Every time I start a new SaaS project or a side hustle, I spend the first 3 hours searching for "Free Admin Templates." And every time, I end up a bit disappointed. Most "free" templates feel like they were frozen in time. They’re often full of ashy greys, clunky borders, and those generic blue primary colours that scream "D...

Stop building what your customers ask for

I was at a conference this week. Bunch of stakeholders on stage. Hospital admins, big-name buyers, a couple of policy folks. The message to founders was loud and clear: "You need to be consulting us. You need to be adapting your products to our suggestions." And honestly? I hated it. Not because they were completely wrong. They were half right. They were just shouting the half that was wrong. ...
