Deep dives
XFCE 4.20 Release
The recent release of XFCE 4.20 marks a significant development milestone, the first major update in nearly two years. One of the most noteworthy features is the experimental Wayland compatibility, which will allow advanced users to explore this new display server protocol. Although the compositor support isn’t built-in yet, users can try integrating it with external compositors like Wayfire. This release has shown extensive improvements in Thunar, the file manager, making it a strong contender among GTK-based desktops.
CentOS Stream 10 Insights
CentOS Stream 10 is gaining attention for its new collaborative approach, as it branches off from Fedora and serves as the foundation for future Red Hat Enterprise Linux (RHEL) versions. The shift to a more open development model allows community contributions, making CentOS Stream 10 valuable for users who want to engage with the latest RHEL features before the official release. It offers users access to modern packages, including Linux 6.12 and GNOME 47, providing a more up-to-date operating system experience. Users can start using it right away without needing restrictions or waiting for the official RHEL 10 launch.
Transition in Fedora Leadership
Fedora’s project leader, Matthew Miller, has announced his decision to step down after a decade in leadership, signaling a potential shift toward new ideas and perspectives. He plans to assist in the transition process and help mentor the next leader to ensure a smooth handover. The timing coincides with the upcoming Fedora 42 release, suggesting a fresh start for the project with new leadership. This change reflects the need for innovation in the community, especially as the Linux desktop landscape evolves.
Exploring Kernel Options
The discussion around custom Linux kernels highlights the potential benefits of experimenting with different kernel versions, such as the Zen kernel and the RT kernel for improved performance. Users have shared personal experiences running the latest kernels and have reported various findings, including better responsiveness and audio performance. Although some faced issues like system locks and increased temperatures, the overall feedback points to a growing interest in kernel customization within the Linux community. This opens the door for more users to consider tweaking their kernels to optimize their system's performance according to their specific use cases.
Voting for the Tuxies
With the upcoming Tuxies awards, there's an urgent call for community participation to ensure the event reflects a wide range of opinions. The hosts emphasize the importance of voting, noting that the Tuxies could be coming to an end if participation does not meet expectations. They encourage listeners to cast their votes at tuxies.party, creating a sense of excitement and urgency ahead of the event. This could be the final opportunity for users to celebrate their favorite projects in the Linux ecosystem, and every vote counts.
