Show HN: I built a guided Build your own DNS Server challenge 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://ift.tt/o5xBGyQ 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 queries. As you go, you'll learn about the DNS protocol, its format, servers, and A records. All while getting to hone your language skills. Some of the challenges and choices I had to make: * To make the stages easier, I had to break them up, such that each step builds on the previous one. This was especially challenging for the 2nd stage, where we write a DNS packet's header contents. Even though I’d have liked it to be easier, breaking it up further would have been weird. * Instead of implementing a recursive resolver, I've restricted to a forwarding server. We made this decision so that most developers can still use it. To add more complexity, we can use a challenge extension (noted below). * Deciding how much instruction and context the stages should provide. I’ve decided to keep them as thorough as possible for most of the stages. Developers can choose to have thorough details or just skim through them. I would love your feedback and questions on the challenge. You can try it out for free here: https://ift.tt/o5xBGyQ (no CC required). I also have challenge extensions planned. You can find them at https://ift.tt/OkvXg9x... . I'm also keen to hear what you think about the extension ideas. https://ift.tt/FwhiSXW November 27, 2023 at 12:06PM

Show HN: Building an Investment Management Powerhouse https://ift.tt/DYkMGwv

Show HN: Building an Investment Management Powerhouse The idea for Stockle came from simply having no usable tools to track, manage and explore investments. It felt like every single one existing platforms lacked even the most basic functionalities. In addition the UIs were not focusing on user experience. The lack of detail in the existing platforms led us to try out a different approach to investment management. Focus points for Stockle have been Modern UI, Detailed coverage on investments and flexible portfolio creation. For future we are focusing on even more personalised features. Feel free to put Stockle-beta to test whether you are an investor or not! Many features still under development but core features are there! Maybe it can even spark up your inner Warren Buffet. Feedback is also appreciated! https://stockle.app/ November 25, 2023 at 10:36PM
