But the raw logs showed different ambient temperatures, different maintenance crew shift changes, different rats scurrying on the rails. How could the thermal data be identical?
Maya sipped cold coffee and watched the log stream. Removing duplicate block: 0x7F3A... Removing duplicate block: 0x7F3A... Over and over. The same hash. The same block. xtool -dd dedup
Maya stared at the terminal. Three months of fieldwork—interviews, recordings, thermal scans, witness statements—all condensed into a 2.4 terabyte dataset. The problem wasn't missing data. It was drowning in it. But the raw logs showed different ambient temperatures,
Removing duplicate block: 0x7F3A... 89%
She paused the process and inspected the block. Metadata: recorded 03:14 AM, Tunnel Section K, thermal camera #2. Timestamp: 2024-10-17. Then again at 2024-10-18. Then 2024-10-19. Every night. Same block. Same bytes. Exactly. Removing duplicate block: 0x7F3A
xtool -dd dedup: Process completed. 99.97% space saved.
"Run xtool -dd dedup ," her supervisor had said. "Standard preprocessing. You'll thank me."
