Tuning a Linux laptop for AI-assisted development

Jordan Dimov describes using Claude Code to diagnose and fix performance problems on his Ubuntu Dell Precision 3591 laptop, including a 90%-full disk from retained Rust debug builds, 30-second SSD freezes caused by Intel VMD (fixed by switching BIOS storage mode from RAID On to AHCI/NVMe), and a GPU kept awake by a kernel flag. Postgres tuning, parallel test databases, and CPU affinity changes cut the full test run from 283 s to 198 s and commits from 0.58 ms to 0.04 ms. He also covers local models on the 6 GB GPU, a pgvector-based code search tool, and a log-digest script for agents.
