There used to be this site called binarysearch.com that let you compete against friends in solving leetcode-style questions but the devs took it down. I'm working on (https://ternarysearch.com), a site with the same mechanics, but a focus on ICPC-style questions. Hoping the competitive programming scene will take a liking to it, I'd love to build a community around open sourcing an online judge.
Seeking a junior/mid dev role at a startup or contract work. I was part of my university's programming team and my team won the ICPC Southeast regionals Div2 contest. I interned at Google as part of the Network Doctor team and have done freelance frontend work for a YC-backed startup.
Most recently, I've been working on a multiplayer leetcode site , and I'd like to go through this list (https://ternarysearch.com), inspired by binarysearch.com, which I'll make open source to give to the community if/when I'll move onto something else.
My other projects include osdev (demo: https://medbar.dev), a discord bot to answer questions about a github repo using RAG, a discord clone to learn system design, a community-driven site that vibe codes itself, and home labbing.
I'm curious of HN's opinions on 4chan's /g/ programming challenges. IMO, the difficulties feel a bit arbitrary - for example, claiming that a basic bootloader is more difficult than a C compiler.
I’m a Software Engineer with ~1 year of experience. In college I had internships at Google and a startup. Since Jan 2025, I’ve done freelance work, including frontend work for a YC-backed startup. I’m interested in systems programming, full-stack, and AI engineering.
I was part of my university’s JV programming team, where we won the ICPC Southeast Regionals Division 2 contest. My codeforces peak rating is 1506 (Specialist).
Recently I've been working on my own OS, where I just added a keyboard driver and makeshift kernel-land shell that can generate a maze and solve it (demo: https://medbar.dev), a discord bot that answers questions about a github repo using RAG, a discord clone to learn system design, a community driven site that vibe codes itself, and I'm currently planning a binarysearch.com clone since the original site went down, which let you compete solving leetcode-style problems against friends.
very surprised this project is still releasing problems weekly - I remember this being up when I was in high school. maybe I'll pick it up again since I only did the first ~30 or so back then.
Not only are they still releasing problems weekly, they have a long backlog of problems waiting for release. I submitted a problem back in April 2024, and it didn't get published until October 2025 (problem 963). There's an excellent core development team that works with problem-submitters to get problems tuned up for Project Euler.
