Show HN: Doom port to pure Go – Gore
Hi HN,
I’ve been working on Gore – a port of the classic Doom engine written in pure Go, based on a ccgo C-to-Go translation of Doom Generic. It loads original WAD files, uses a software renderer (no SDL or CGO, or Go dependencies outside the standard library). Still has a bit of unsafe code that I'm trying to get rid of, and various other caveats.<p>In the examples is a terminal-based renderer, which is entertaining, even though it's very hard to play with terminal-style input/output.<p>The goal is a clean, cross-platform, Go-native take on the Doom engine – fun to hack on, easy to read, and portable.<p>Code and instructions are at <a href="https://github.com/AndreRenaud/Gore" rel="nofollow">https://github.com/AndreRenaud/Gore</a><p>Would love feedback or thoughts.

Show HN: Omnara – Run Claude Code from anywhere
Hey ya’ll, Ishaan and Kartik here. We're building Omnara (<a href="https://omnara.com/">https://omnara.com/</a>), an “agent command center” that lets you launch and control Claude Code from anywhere: terminal, web, or mobile — and easily switch between them.<p>Run 'pip install omnara && omnara', and you'll have a regular Claude Code session. But you can continue that same session from our web dashboard (<a href="https://omnara.com/">https://omnara.com/</a>) or mobile app (<a href="https://apps.apple.com/us/app/omnara-ai-command-center/id6748426727">https://apps.apple.com/us/app/omnara-ai-command-center/id674...</a>).<p>Check out a demo here: <a href="https://www.loom.com/share/03d30efcf8e44035af03cbfebf840c73" rel="nofollow">https://www.loom.com/share/03d30efcf8e44035af03cbfebf840c73</a>.<p>Before Omnara, we felt stuck watching Claude Code think and write code, waiting 5-10 minutes just to provide input when needed. Now with Omnara, I can start a Claude Code session and if I need to leave my laptop, I can respond from my phone anywhere. Some places I've coded from include my bed, on a walk, in an Uber, while doing laundry, and even on the toilet.<p>There are many new Claude Code wrappers (e.g., Crystal, Conductor), but none keep the native Claude Code terminal experience while allowing interaction outside the terminal, especially on mobile. On the other hand, tools like Vibetunnel or Termius replicate the terminal experience but lack push notifications, clean UIs for answering questions or viewing git diffs, and easy setup.<p>We wanted our integration to fully mirror the native Claude Code experience, including terminal output, permissions, notifications, and mode switching. The Claude Code SDK and hooks don't support all of this, so we made a CLI wrapper that parses the session file at ~/.claude/projects and the terminal output to capture user and agent messages. We send these messages to our platform, where they're displayed in the web and mobile apps in real time via SSE. Our CLI wrapper monitors for input from both the Omnara platform and the Claude Code CLI, continuing execution when the user responds from either location. Our entire backend is open source: <a href="https://github.com/omnara-ai/omnara" rel="nofollow">https://github.com/omnara-ai/omnara</a>.<p>Omnara isn't just for Claude Code. It's a general framework for any AI agent to send messages and push notifications to humans when they need input. For example, I've been using it as a human-in-the-loop node in n8n workflows for replying to emails. But every Claude Code user we show it to gets excited about that application specifically so that’s why we’re launching that first :)<p>Omnara is free for up to 10 agent sessions per month, then $9/month for unlimited sessions. Looking forward to your feedback and hearing your thoughts and comments!

Show HN: Play Pokémon to unlock your Wayland session
Hello everyone!<p>I've created a gameboy emulator to unlock my Wayland session and wanted to share this project to everyone here!<p>I've been a Linux enthusiast since I was a kid. What always captivated me was the freedom to customize my system exactly the way I wanted. With Wayland, we've reached an incredible level of performance. It's like turning your operating system into a video game! I've always been fascinated by the blend of fun and the serious, technical nature of an OS. That’s what inspired me to create this project.<p>I started by studying Wayland, its protocol and how to build a compositor. Then I became particularly intrigued by the concept of a locker, which reminded me a bit of an escape game. That’s when I thought: how cool would it be to solve a puzzle to unlock your session, instead of just typing a password? Since I’ve worked with emulators in the past and I’m a huge Pokémon fan, the idea of building the puzzle around that game came to me instantly!<p>Technically, the locker code and the wayland protocol have been implemented from scratch ( using EGL and wl_keyboard_listeners ).
My locker runs a version of the gbcc emulator modded by myself. This emulator waits for one precise value to be set in a given memory address.<p>I have modded the Pokémon game to my needs: when the password is good, I put the good value in the good memory address so the emulator knows it needs to unlock the session.<p>Hope you will appreciate this project!
