It's FOSS, Friday, July 17th, 2026
Humble Bundle and O'Reilly are offering 15 DRM-free Linux eBooks in two tiers, with proceeds supporting Code for America.
The "Linux: All the Things" bundle offers progressive learning paths at two price points.
For $5.90, the first tier provides five books focused on Git workflows and Linux internals, including system programming and kernel topics.
The full collection at $29.50 adds ten more books covering command-line basics, modern Linux practices, security testing with Kali Linux, and container orchestration with Kubernetes.
All titles are delivered as DRM-free PDFs and ePUBs for permanent ownership. A portion of proceeds supports Code for America, a nonprofit working to improve access to government services.
