Show HN: I missed the moving blocks, so I built a real Linux disk defragmenter
Summary
Show HN introduces Defragger, a real graphical disk defragmenter for Linux written in Rust and Qt. It visualizes fragmentation, can defragment ext4 and offline FAT volumes, and uses PolicyKit to keep privileged operations separate; the project is in alpha and includes safe run-from-source instructions and architecture notes. The post highlights open-source tooling and a personal need that led to a reproducible storage layout tool.
