  An arbitrary filesystem event watcher which is: - simple - efficient - dependency free - runnable anywhere with a filesystem - header only Watcher is extremely efficient. In most cases, even when scanning millions of paths, this library uses a near-zero amount of resources. Watcher is simple. The library exposes a single function and a single object. That is all. Happy hacking.

  Osint tool that finds exposed files on domainsJul 2026 · search.cerast-intelligence.com · ▲58

  hey guys, wanted to show one of my side projects i just made public. the idea is basically another osint tool for pentesters and bug bounty hunters. it watches certificate transparency logs and checks newly-seen domains for exposed stuff like .env files, open .git dirs, config files, db dumps and so on, and puts whatever it finds into a searchable db. you just search a domain (or part of one) and see what's exposed. it's read-only and free. one thing i've been thinking about adding is a way to register for certain keywords and get notified when something new shows up for that search. would…

  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…
