Graveyard
One dead-code scanner for mixed-language repos
What it does
Graveyard helps teams find dead code in mixed-language repos without stitching together separate tools per ecosystem. It scans Python, JS/TS, Go, and Rust in one pass, ranks findings with git-aware confidence scoring, and makes adoption practical with baseline diffs for CI ratchets. It also outputs JSON, CSV, and SARIF for automation and code scanning.

- CACodeTracer – A time-traveling debugger implemented in Nim and Rust2025 · github.com · ▲334
Hey! We are presenting CodeTracer - a user-friendly time-traveling debugger designed to support a wide range of programming languages: https://github.com/metacraft-labs/codetracer?tab=readme-ov-f... CodeTracer records the execution of a program into a sharable self-contained trace file. You can load the produced trace files in a GUI environment that allows you to move forward and backward through the execution and to examine the history of all memory locations. They say a picture is worth a thousand words — well, a video is even better! Watch the demo below to see…

- GAGitdot – A better GitHub. Open-source, written in RustJun 2026 · gitdot.io · ▲334
What works now: user signups, org creations, private/public repos, and importing GitHub repositories (both as read-only mirrors and full migrations). So basically, you can create, push and pull to a repo, but we don't have many features quite yet (issues, PRs, CI). What is a bit unique is: 1) we built it in Rust and 2) the website is a little odd. Its design is inspired by CLIs (e.g., fzf, broot, vim) instead of web apps, and as such, lacks some affordances that you might typically expect in favor of keyboard-driven instant navigations (we have the very ambitious goal of an FCP of…
- DMDead man's switch without reliance on your infra2024 · github.com · ▲139
I wrote this Go project to implement a dead man’s switch that didn’t rely on cron jobs, timers, databases, etc on the infra it runs on. Deadcheck integrates to PagerDuty and keeps a long running incident snoozed until expected check-in times where it’ll alert unless a check-in occurs.

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
