Show HN: I built a "sudo" mechanism for AI agents Hi HN, I’m Yaron, a DevOps engineer working on AI infrastructure. I built Cordum because I saw a huge gap between "AI Demos" and "Production Safety." Everyone is building Agents, but no one wants to give them write-access to sensitive APIs (like refunds, database deletions, or server management). The problem is that LLMs are probabilistic, but our infrastructure requires deterministic guarantees. Cordum is an open-source "Safety Kernel" that sits between your LLM and your execution environment. Think of it as a firewall/proxy for agentic actions. Instead of relying on the prompt to "please be safe," Cordum enforces policy at the protocol layer: 1. It intercepts the agent's intent. 2. Checks it against a strict policy (e.g., "Refund > $50 requires human approval"). 3. Manages the execution via a state machine. Tech Stack: - Written in Go (for performance and concurrency)....

Show HN: DailySpace – Daily astronomy photos with rocket launch tracking I built DailySpace because I wanted a better way to explore space imagery beyond endlessly scrolling through search results. The app features a curated collection of thousands of cosmic images organized into categories like galaxies, nebulae, Mars, and black holes. Each photo comes with explanations that make the science accessible. I recently added rocket launch tracking with detailed mission data from space agencies worldwide. The architecture focuses on discoverability-you get a featured photo daily, but you can also browse categories or search the full collection. The dark-themed UI is optimized for viewing space imagery without eye strain.Free tier covers daily photos and basic browsing. Premium unlocks unlimited search results, unlimited favorites, and cross-device sync. What started as a personal project to learn more about astronomy turned into something I use every day. The two-minute daily habit of openi...

Show HN: HORenderer3: A C++ software renderer implementing OpenGL 3.3 pipeline Hi everyone, I wanted to share a personal project I've been working on: a GL-like 3D software renderer inspired by the OpenGL 3.3 Core Specification. The main goal was to better understand GPU behavior and rendering pipelines by building a virtual GPU layer entirely in software. This includes VRAM-backed resource handling, pipeline state management, and shader execution flow. The project also exposes an OpenGL-style API and driver layer based on the official OpenGL Registry headers, allowing rendering code to be written in a way that closely resembles OpenGL usage. I'd really appreciate any feedback. https://ift.tt/7RMuEK3 January 18, 2026 at 12:34AM

Show HN: What if your menu bar was a keyboard-controlled command center? Hey Hacker News The ones that know me here know that I am a productivity geek. After DockFlow to manage my Dock and ExtraDock, which gives me more space to manage my apps and files, I decided to tackle the macOS big boss: the menu bar. I spend ~40% of my day context-switching between apps — Zoom meetings, Slack channels, Code projects, and Figma designs. My macOS menu bar has too many useless icons I almost never use. So I thought to myself, how can I use this area to improve my workflows? Most solutions (Bartender, Ice) require screen recording permissions, and did not really solve my issues. I wanted custom menus in the apps, not the ones that the developers decided for me. After a few iterations and exploring different solutions, ExtraBar was created. Instead of just hiding icons, what if the menu bar became a keyboard-controlled command center that has the actions I need? No permissions. No telemetry. Just loc...

Show HN: Reddit GDPR Export Viewer – Built After Ban, Unban, Reban Show HN: Reddit GDPR Export Viewer – Built After Getting Hacked, Reinstated, Then Banned Again A few months ago, I posted here about getting my 10-year Reddit account hacked despite 2FA: https://ift.tt/LVRFtlY The likely culprit: session cookie theft via a malicious browser extension, possibly linked to the ShadyPanda campaign that infected 4.3M browsers. Reddit eventually reinstated my account with zero explanation. Then, exactly one month later, they banned me again – permanently, with no reason given and no appeal process. This drove home a lesson: platforms can and will revoke your access arbitrarily, taking years of contributions with them. So I requested my GDPR data export. What I received was not really usable: raw CSV files with no way to meaningfully browse a decade of comments, posts, and activity. So I built this: https://ift.tt/iCozPlD It's a pure client-side viewer – zero backend, your data never leave...

Show HN: I built a tool to assist AI agents to know when a PR is good to go I've been using Claude Code heavily, and kept hitting the same issue: the agent would push changes, respond to reviews, wait for CI... but never really know when it was done. It would poll CI in loops. Miss actionable comments buried among 15 CodeRabbit suggestions. Or declare victory while threads were still unresolved. The core problem: no deterministic way for an agent to know a PR is ready to merge. So I built gtg (Good To Go). One command, one answer: $ gtg 123 OK PR #123: READY CI: success (5/5 passed) Threads: 3/3 resolved It aggregates CI status, classifies review comments (actionable vs. noise), and tracks thread resolution. Returns JSON for agents or human-readable text. The comment classification is the interesting part — it understands CodeRabbit severity markers, Greptile patterns, Claude's blocking/approval language. "Critical: SQL injection" gets flagged; "Nice refactor!...
