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.

Gives "Non-Image content-type returned", I guess GH doesn't like hot-linking its hosted user assets.

Might want to link the `.md` that embeds it instead, if any


Visualizing Complex Analysis by Tristan Needham is another good one IMO


Merry Christmas HN! Hope you're all enjoying quality time with loved ones (and good food!)

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.

very surprised I haven't seen this done before - cool idea!


Probably because security nightmare
