Save Time with Modern Search Techniques - Mark Jeanmougin


Many of our tools and techniques for working with large data sets are tweaked versions of what we did back when we had one CPU and a mechanical hard drive. This presentation explores how to approach these data sets with multi-core CPU's and fast NVMe storage. Special attention is paid to Digital Forensics & Incident Response (DFIR) use cases, but the techniques are more general. This is a trip into GNU Parallel, xargs, and other techniques to maximize the parallel processing capabilities of modern CPU's and storage. Examples include searching, anti-virus, and photo processing.
