I built a Chrome extension that tests web forms with AI

Dev log #1 Hi, I'm Denyse. I'm a software engineer, and for the past two months I've been building a tool I'm genuinely excited about. It's a Chrome extension that takes a requirements document, uses AI to generate test cases, and then drives a real web form the same way a human QA tester would filling fields, clicking dropdowns, reading validation messages, and producing a pass/fail report. I'm calling it QA Helper, and I'm going to start writing about it every week. Some weeks will be deep tec

How I Used the JVM’s JDWP to Cut GlassFish Redeploys from 2 Minutes to 5 Seconds

Building a command-line hot-swap workflow for GlassFish using JVM debugging internals: no IntelliJ Ultimate, no JRebel, no custom JVM. Repo: glassfish-hotswap-cli If you've worked on a Jakarta EE application running on GlassFish, you probably know this routine. Change a line of Java. Save. Rebuild the WAR. Wait while it undeploys, redeploys, and re-warms CDI, EJBs, JPA, JSF, and everything else. Then finally refresh the browser. By the time the deploy log finishes scrolling, you've forgotten wha

How I use pluckmd to read blogs with an AI agent

I wanted to read blog posts with an LLM in the loop, not just on my own. The push came from two places. Karpathy's LLM Wiki idea, where the model keeps a folder of markdown notes as you learn a topic. And Thariq's post on how well Claude generates interactive HTML, which is now on the Anthropic blog. Put together, the workflow I wanted looked like this: pull blog articles into markdown, have an agent index them into a wiki, then generate interactive HTML pages to learn from. Step one was the blo

Run Claude Code For Free (for Fun and Profit)

Uber blew through its entire 2026 IT budget on AI in 4 months. The State of FinOps Report now lists "FinOps for AI" as the number one priority for 2026 — surpassing traditional cloud cost optimization for the first time. And in typical fighting-an-AI-problem-with-more-AI fashion, Google announced a FinOps Explainability agent at Cloud Next '26 whose entire job is to autonomously investigate why your other AI is costing so much. They also shipped Spend Caps that literally pause your API traffic w

Segment Trees: The “Divide‑and‑Conquer” Trick That Actually Makes Sense

Segment Trees: The “Divide‑and‑Conquer” Trick That Actually Makes Sense Quick context (why you're writing this) I remember the first time I saw a segment tree in an interview prep book. The diagram looked like a binary tree slapped onto an array, and the explanation was basically “just trust me, it works.” I spent three hours staring at the picture, trying to convince myself that the magic wasn’t just a clever coincidence. When I finally walked through a concrete example—say, asking

First Post

I was looking for a platform to document my journey toward becoming an AI researcher, and I finally ended up at dev.to. I’ll be posting about the things I try — what works, what fails, and the thought process behind each experiment. I also want to dive into the research and reasoning behind why certain approaches succeed while others don’t. Hopefully, this helps me keep track of everything I’ve been working on, while also connecting me with people who enjoy the kind of work I do — and with those
