Understanding App Architecture - Why It Matters

A student's journey from "just making it work" to writing better Android code INTRODUCTION When I first started learning Android development, I thought my work was done when my app ran without crashing. I would write code, click run, and if the app worked, I was happy. But as I built more features in this course, I discovered that making an app work and building an app well a...

#tag:-A Simple Recon Workflow for Beginner Bug Hunters

Description I have prepared a basic step-by-step workflow beginners can follow when starting reconnaissance on a target. A structured reconnaissance workflow helps bug bounty hunters investigate targets efficiently. Instead of randomly testing a website, researchers follow a sequence of steps to gradually reveal the attack surface. The process usually begins with identifying the main domain pro...

Designing a File Tampering Detection Tool for a Legacy PHP Application

I work on a legacy PHP application that runs on AWS EC2. The application is deployed from a deploy server with rsync. In this environment, I needed a practical way to detect file tampering on application servers. Existing tools did not fit this deployment model well, so I built a small Go tool called kekkai and open-sourced it. In this post, I want to explain not only the design choices, but also...

[AskJS] Tools to Learn JS (as a beginner)

Hi all, I'm a web dev and teacher (sometimes). I've been tinkering with a little tool to help students learn Javascript. Not deeply, but to teach them those initial steps of learning syntax and how to bring things together. Just the basics. I'll probably share it in the near future. I know there are free resources like freecodecamp and others, and I'm wondering: What most helped you when you star...

Serverless Node: What It Is, How It Works, and When to Use It

What "Serverless Node" Actually Means in 2026 "Serverless" is one of those terms that sounds more complex than it is. Serverless Node is the model of running Node.js applications without managing any server infrastructure. The servers are still there; they belong to your cloud provider. AWS, Azure, and Google Cloud manage provisioning, scaling, security fixes, and teardown. Your team wr...

Transparent COM instrumentation for malware analysis

Cisco Talos has released DispatchLogger, a new open-source tool designed to provide high visibility into script-based malware that leverages Windows COM (Component Object Model) automation. By intercepting late-bound IDispatch interactions through transparent proxying, the tool bridges the gap between low-level API monitoring and high-level semantic analysis. This approach allows analysts to captu...

How I built a Discord-style Rich Link Preview in React (Bypassing CORS)

Hey guys, I was getting super frustrated trying to scrape OpenGraph tags from the frontend and getting blocked by CORS. I didn't want to spin up a whole Node.js backend just for this, so I wrote a component that uses a free Rust-based utility API to do the scraping securely. Wrote up a quick tutorial with the source code here if anyone needs it for their projects! https://dev.to/amajid/build-disco...

Vite vs Webpack: Build Tool Comparison for Modern Web Development (2026)

The JavaScript build tool landscape has undergone a seismic shift. For nearly a decade, Webpack dominated frontend tooling — bundling everything from React apps to enterprise dashboards. Then Vite arrived, leveraging native ES modules to deliver near-instant dev server startup and lightning-fast hot module replacement. By 2026, the question is no longer "should I try Vite?" but "is there a reason ...

Have you ever tried to build a link preview card—like the ones you see in Discord, Twitter, or Slack—only to be instantly blocked by CORS errors? If you try to fetch a URL directly from your frontend React application to scrape its <meta> tags, the browser's security model will stop you in your tracks. You have to do this from a backend. But instead of spinning up a whole Node.js/Puppetee...
