  DN$ – an innovative, ad-supported DNS resolver2024 · github.com · ▲294

  Tired of companies snooping through your DNS traffic? Don't you wish you could get advertisements with your DNS records? Today we're introducing the innovative, privacy-focused, ad-supported DNS resolver - DN$! Traditional DNS resolvers provided by your internet service provider, cloudflare, or google could be tracking your internet activity and selling it to third-party data vendors. We at DN$ want to fix that and cut out these nefarious actors (until we've amassed a critical number of users to exploit). In order to support such a radically new business model, our service needs to serve…

  I built a guided Build your own DNS Server challenge2023 · app.codecrafters.io · ▲57

  Hey everyone. It's Sherub here, author of the Build your own DNS Server challenge on CodeCrafters. Currently it’s available in Rust, Go, and Python and is free while in beta. https://codecrafters.io/dns-server I've kept the challenge accessible but still challenging for an intermediate developer. This challenge, like others from CodeCrafters, is self-paced. You can use any tools you prefer (terminal, editor, etc.) to build the project. At the end of the challenge, you will have created a DNS forwarding server. The server can create and read DNS packets and respond to DNS…

  Shiddns a DNS learning experience in Python2024 · github.com · ▲7

  Hi HN, as a learning experience, I created a small DNS resolver with blocking capabilities and resolution of local host names. There are already tons of good ad-blocking DNS implementations out there. And they do this much better than my implementation. Great examples are Blocky or pihole. So when I set out to "play around", I looked at these projects and tried to modify them. Fortunately for them, but unfortunately for beginners, these are already quite far developed and complex projects. So impatient me set out to "quickly write something in Python". Almost two weekends later, I put in so…

  Talanoa▲343

  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…
