In plain words

CrossHair is a testing tool for Python developers that automates the process of finding bugs in code. It uses symbolic execution and property-based testing to generate test cases automatically, helping developers discover edge cases and potential failures without writing extensive manual tests. The tool integrates with existing Python projects and is designed to complement traditional testing approaches by exploring code paths systematically.

  • Browser-based XSS scanner2024 · github.com · ▲57

    This is a simple single-file python program that can find basic XSS (cross-site scripting) vulnerabilities in a target url. Most XSS discovery tools use a payload refelection strategy in which payloads are injected in url parameters and the GET response is inspected for places where the payload content is reflected. This is a very low precision XSS detection strategy because most reflection does not support execution. This program uses a different approach, and instead opens the target url in a browser, tests alert(...) payloads directly in the browser context, and listens for an alert being…

  • Talanoa▲340

    Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

    Hey folks. Last year I was fortunate enough to sign a deal to write a book with my favorite technical publisher, The Pragmatic Bookshelf. When I started out as an Engineering Manager many years ago, I found that there wasn't a huge amount of material that specifically and practically helped me understand how to do my job. When you learn to program there's all of these amazing tutorials, examples and guides, but what was there for new managers? In response to this, a couple of years ago I started a blog over at https://www.theengineeringmanager.com which got a decent amount of…
