Page: Feed: --- ## [RSC Flight Protocol](https://blog.c0nrad.io/posts/rsc-flight-protocol/) _2026-03-13 · c0nrad's c0rner_ I’m currently building an app using Next.js ( dmarcdefender.io ). I’m not sure how I feel about it (it being Next.JS, dmarcdefender is amazing). It’s both amazing and terrifying, seamlessly jumping between client-side and server-side code. I don’t really like magic, but it is nice having one single environment, one set of types, complete DRY across the client and… ## [Recursive Dns Resolver](https://blog.c0nrad.io/posts/recursive-dns-resolver/) _2026-03-12 · c0nrad's c0rner_ Overview Today’s project is to make yesterday’s stub resolver a recursive resolver. Specifically I want to start with the root.hints and go down the chain till I get the A record for c0nrad.io. https://gist.github.com/c0nrad/8497352c18d27b93c67a530663335a55 Steps Ask D.ROOT-SERVERS.NET (NASA) for the NS record of .io Ask a0.nic.io for the NS of… ## [DNS Stub Resolver](https://blog.c0nrad.io/posts/dns-client/) _2026-03-11 · c0nrad's c0rner_ I realized I haven’t done much learning in a while ( https://dmarcdefender.io is my current project, but it’s just standard SaaS work). So I figured I might try to spend an hour or two each day learning something new. Today’s project was building a super simple DNS resolver. The goal was just to resolve the A record for c0nrad.io into an IP address. ## [Brainstorming Pathfinding Algorithms: QuadTree & RelaxPath](https://blog.c0nrad.io/posts/pathfinding/) _2025-12-02 · c0nrad's c0rner_ I had an idea for a fun “grid search” pathfinding algorithm for MIT battlecode, so decided to write a little playground in JS. This article covers the results. ## [SWU Card Reader Neural Net P1](https://blog.c0nrad.io/posts/swu-card-nn-p1/) _2025-07-09 · c0nrad's c0rner_ New project! Using AI to read SWU card aspects. I just finished a coursera course on Deep Learning and Neural Networks so figured I’d try to do something with my newfound knowledge! In this project I’ll be building some NN (Neural Networks) manually that will take in a Star Wars Unlimited card image and determine if “isHeroic”, “isVillainous”,… ## [SWU Health Counter](https://blog.c0nrad.io/posts/swu-health-counter/) _2025-06-28 · c0nrad's c0rner_ A new electronics project! It’s a simple circuit that just keeps track of base health for Star Wars Unlimited (SWU) trading card game. This was my first time making/ordering a PCB, and I learned a lot along the way. Problem Statement To keep track of your base health in SWU, people usually use little damage tokens (in increments of 1/3/5/10), or dice. But I don’t like… ## [Reasons to Not Be Hard on Yourself (CTFs)](https://blog.c0nrad.io/posts/be-kind-to-self/) _2024-12-31 · c0nrad's c0rner_ Every once in a while I either get a Discord message or see a post about someone who is feeling down about not doing well on CTFs. To be honest, I also sometimes make the mistake of feeling down when I compare myself to others. As we go into 2025, here are my opinions on why we both shouldn’t be too hard on ourselves. 1. CTFs are not “Real World” Security
