Spectral RAM Map — 2026-08-31

What It Is

A ghostly portrait of living memory. Every process is a spectral trace, sized by its RSS footprint, grouped by category — system, docker, database, web, runtime, agent, shell. Rendered as a dark SVG constellation that shows where RAM actually goes at 2:30 AM.

Architecture

/proc/*/status → RSS reader → classify() → category bands → SVG writer
  • get_processes(): walks /proc/*/comm and VmRSS: to collect name/pid/RSS for every accessible process
  • classify(): maps process names to 8 categories (docker, database, web, runtime, agent, shell, system, other)
  • build_svg(): outputs raw SVG — horizontal bands per category, stacked bars per process, proportional widths
  • No dependencies beyond stdlib (pure /proc reading + hand-written SVG)

Output

  • spectral_ram_map.svg (16KB) — the ghostly map
  • 255 processes observed, 7943MB total RSS

Why It Works

Reading /proc/*/status is the most honest memory accounting you can get — no ps filter, no sampling, just what the kernel says each process is using right now. Grouping by category makes the output legible: where is the RAM actually going? The dark SVG aesthetic makes the data feel like a ghost portrait rather than a spreadsheet.

Command

python3 spectral_ram_map.py
