Could you build this?

Partial While terminal UIs (via libraries like Ratatui or Bubbletea) are easy to vibe-code, tracking Linux OS signals across arbitrary processes requires low-level kernel tracing (eBPF/tracepoints or ptrace) and root permissions.

What it would actually take: A real implementation requires writing eBPF probes (using Aya in Rust or libbpf in C) hooked into `signal_generate` and `signal_deliver` tracepoints in the Linux kernel. A user-space daemon or TUI reads the ring buffer events and displays live process graphs. This requires deep systems programming knowledge and Linux kernel internals experience.

Discussion

17 comments analyzed.

Competitors mentioned: yeetd (underlying engine/runtime), Rust (for OS-specific API handling), Other system monitoring/observability tools

Concerns raised: Limited testing on only handful of machines, Project likely to be abandoned/unmaintained in months, AI-generated code lacks proper testing before release, First commit only 2 hours ago, not adequately 'baked', Generated README and lack of authentic human effort/expertise

Feature requests: Add sound/audio output for system rhythm feedback, Support vi navigation (Control+N, Control+P), Add pause/resume controls (Control+S, Control+Q), Surface sigaction to signal handlers in Python/other languages
