Adding a Trust Boundary to a LlamaIndex RAG Pipeline

Adding a Trust Boundary to a LlamaIndex RAG Pipeline

Your LlamaIndex app does not only retrieve documents. It decides which external text is allowed to become model context. That is a trust decision, even if your code does not call it one. A PDF can contain useful facts. A support ticket can contain real customer context. A web page can contain documentation. An email thread can contain the answer your user needs. But all of those sources can al...

React Router v6 throwing "Uncaught TypeError: Cannot read properties of null (reading 'useRef')" and "Invalid Hook Call"

I am facing a "White Screen of Death" when using react-router-dom (v6) in my React application. The terminal shows a successful build, but the browser console throws multiple errors related to Hooks and useRef. Even with a fresh create-react-app and a simple Router setup, the issue persists. Uncaught TypeError: Cannot read properties of null (reading 'useRef') - occurring at BrowserRout...

France Sirene + RNE — post-canonicalisation API guide

Until 2023, the canonical French company register was a four-way fragmented mess: INSEE Sirene held the identification layer (SIREN, SIRET, name, address, headcount, NAF activity code), the regional Greffes held statutory acts (incorporation deeds, capital changes, director appointments), the Tribunaux de Commerce shared partial data through Infogreffe (paid), and the Bodacc was the gazette. Start...

Glassdoor API in 2026: Why Developers Are Switching to Web Scraping

Glassdoor API in 2026: The Landscape Has Changed If you’ve tried accessing Glassdoor’s API recently, you already know: the public API is gone. Glassdoor shut down open developer access and now only offers data through enterprise partnerships with undisclosed pricing. This leaves thousands of developers, recruiters, and data analysts in the dark. Whether you’re building a salary compari...

I Backtested 96 SPY Put Credit Spread Strategies - Here's the Bug Log

I built a backtest engine for SPY put credit spreads. 7 years of 1-minute option chains. 96 grid cells across (delta, DTE, profit-target, stop-loss). 16,024 trades that survived validation. This post is the part most quant tutorials skip: the bugs, the lying simulators, and the one-line feature that humiliated my 3-layer composite signal. If you've ever shipped a backtest with great-looking numbe...

SPXW 0DTE: What Every Developer Building Options Tools Needs to Know

If you've built anything involving options data, you've probably noticed that "SPX 0DTE" is everywhere on fintwit, Discord, and trading blogs. The thing most guides gloss over is that plain SPX doesn't actually have same-day expirations every day. What everyone means when they say "SPX 0DTE" is SPXW — a different ticker with different settlement and different Greeks behavior. I build an options a...

Confessions of a Dark Mode Zealot: When a Setting Becomes a Religion

We need to talk about white light. Specifically, why we react to it like it’s a physical assault. It was around 11 PM last night. My room was a pitch black sanctuary. My OS? Dark. My IDE? Midnight black. My terminal? A void so deep it could swallow light. I even have a browser extension that forces a dark theme onto every single website, regardless of the designer’s original intent. I was in tot...

Beyond the Chatbot: A First Look at the Gemini Agent Development Kit (ADK)

This is a submission for the Google Cloud NEXT Writing Challenge Google Cloud NEXT ‘26 has made one thing abundantly clear: we are officially shifting from the "Chatbot Era" to the "Agentic Era." When building complex applications—especially those integrating multi-modal AI or vision agents with sleek user interfaces—the biggest bottleneck has always been orchestration.

The Accordion Pattern: Why I stopped writing one fat LLM prompt

Most structured-extraction tutorials look the same. Take a document, write one big prompt that says "extract A, B, C, D, E, F", get JSON back. Done. This works on short inputs. It quietly breaks on long ones. After running this in production for a while, I stopped doing it. Here's what I switched to and why. The fat prompt problem Say you have a 50-page report and you want a stru...

Alternatives to Piston API for running code with free daily credits

I was using the Piston API (github.com in Bing) to run code and submit test cases in my project. It worked well because it was free and had no token limits. However, since the public endpoints were recently locked down, my project has stalled. I’m looking for alternatives that: Provide an API for running code in multiple languages Offer at least ~200 free credits per day (or a similar quota) Ar...
