Talks
Here’s a list of my talks, presentations, and interviews.
QubesOS: Security Through Isolation
DevConf 2025
Qubes OS achieves robust security through virtualization-based compartmentalization, isolating different tasks in separate virtual machines to prevent a single compromise from affecting the entire system.
OpenSSH Supply-Chain Attack
A deep dive into the sophisticated three-year supply-chain attack (CVE-2024-3094) on XZ Utils that nearly compromised SSH servers worldwide, revealing critical vulnerabilities in open-source security and trust-based collaboration.
Linux File Systems
Operating Systems course at the Faculty of Informatics, Masaryk University
A deep dive into Linux file system internals - from VFS abstractions and the I/O stack to crash consistency mechanisms and emerging storage technologies.
Interview: The ext4 filesystem is still relevant
DevConf 2014
In this 2014 interview with Linux EXPRES at DevConf.cz, I discuss my work developing the ext4 filesystem at Red Hat and why it continues to evolve rather than being replaced by newer alternatives.
Advanced Features of File System and Storage
DevConf 2014
In this talk I discussed advanced features recently implemented in Linux local file systems, including checksumming, snapshotting, and support for emerging storage technologies.
System Storage Manager
LSF/MM summit 2013
System Storage Manager provides a unified command-line interface for managing multiple Linux storage technologies including LVM, btrfs, encrypted volumes, and mdraid.
Local file systems update
DevConf 2013
This 2013 talk examined the evolution of Linux's major local file systems - XFS, ext4, and Btrfs - as they adapted to modern scalability, reliability, and storage technology challenges.
Btrfs: Design, Implementation and the Current Status
DevConf 2012
Technical presentation examines design and implementation of Btrfs file system in the Linux kernel.
Performance evaluation of Linux Discard Support
DevConf 2011
Technical presentation examines Linux's implementation of discard/TRIM support for SSDs and thinly provisioned storage.
