Untitled Linux Show 251

Untitled Linux Show #251 — Summary

Top tech news & analysis

• Wayland + KDE

  • KWin merged a merge request enabling independent virtual desktops per monitor (planned for Plasma 6.7). This solves a ~20-year limitation rooted in X11/EWMH and lets each screen track its own desktop (e.g., chat on one, code on another).
  • Highlight: the fix came from a new contributor who moved to Wayland for fractional scaling.

• Old-bug discovery & fixes

  • Enlightenment E16: a 20+ year-old hang (triggered by a long PDF filename) was discovered and fixed by a graduate student. Coverage praised this as an example of open-source debugging and maintenance of legacy stacks.

• X.Org security problems

  • Multiple vulnerabilities were disclosed in X.Org Server (integer overflow, out-of-bounds reads, use-after-free, buffer overflow). Many of the vulnerable code paths trace back decades.
  • Discussion reinforced the push from X11 to Wayland for modern desktop security and architecture.

• Kernel & filesystems

  • NTFS on Linux:
    • NTFS3 (Paragon) is upstream.
    • A new “NTFS Plus” implementation (aiming for better performance, maintainability, journaling, and io_map/no-buffer-head semantics) has been proposed and merged into linux-next / the 7.1 window.
    • Benchmarks show multi-threaded throughput gains versus NTFS3. NTFS3 will remain while NTFS Plus is evaluated.
  • 32-bit deprecation signals:
    • Kernel changes include removal of old Intel 486 config options (Linus accepted the MR) and widening the iode field to 64-bit.
    • Discussion about increasing difficulty/impact for legacy 32-bit platforms.

• Distros & releases

  • Fedora:
    • Fedora 44 release delayed one week to April 28 due to blockers.
    • Fedora 45 proposal considers building/packaging for x86_64-v3 (targeting ISA features like AVX/AVX2, FMA; AVX512 is x86_64-v4). DNF may select the highest compatible baseline packages; this raises caveats for mixed/upgrade scenarios.
  • AlmaLinux:
    • Adding i686 user space to support 32-bit userspace compatibility on x86_64 installs.
  • Linux Mint:
    • Moving to a longer development cadence; Linux Mint 23 now targeted for December 2026.
    • Focus on stabilizing Cinnamon and removing lingering X11 dependencies; realistic Wayland/Cinnamon maturity is expected much later (estimates pushed to end of 2027).
  • openSUSE Tumbleweed:
    • Switched installer default for new installs from GRUB2-BLS to systemd-boot.
    • GNOME 50 has landed in Tumbleweed’s stable repo.

• Hardware review highlight

  • Intel Core Ultra 7 270K Plus (Aero Lake refresh) — reviewed by Michael Larabel (Phoronix):
    • Specs: 24 cores (8 P + 16 E), up to 5.5 GHz TBMT, DDR5-7200 support, 125W base / 250W turbo.
    • Price/performance: favorable value vs AMD alternatives (close to AMD top-performer at a lower price).
    • Memory speed from 6400 → 7200 MT/s gave only ~1% average benefit.
    • Overall the 270K Plus was ~2% faster than the 285K while being cheaper.
    • Notes: limited stock, price fluctuation, and socket/motherboard lifecycle caveats.

• AI & projects

  • Mozilla “Thunderbolt” announced — an open-source platform for running agentic/local AI clients, extensible and able to connect to ACP-compatible agents and the Hastack AI platform. Positioned as a sovereign AI client for enterprise/assistant use cases. Reactions mixed on usefulness, name, and strategy.

• Licensing & FSF

  • OnlyOffice licensing controversy:
    • OnlyOffice added extra terms to AGPL-licensed distribution.
    • The Free Software Foundation stated you cannot attach additional restrictions and still call it AGPL; FSF urged OnlyOffice to clarify and remove further restrictions.
    • Discussion covered compatibility of extra terms with GPL/AGPL and limits on forking.

Tools, tutorials & demos mentioned

• Container GUI for KDE

  • “container” (uses a K): a Qt/QML/Kirigami GUI for managing Distrobox containers (create/clone/start/stop, open terminal inside container, auto-detect package manager, install packages). An article/how-to by Bobby Boris was recommended for installation steps.

• Network & terminal utilities

  • netwatch (netwatch-2): terminal GUI to monitor network usage, top connections, packet capture, topology, latency/loss, and more — interactive keyboard-driven dashboard.
  • WTF util: modular terminal dashboard system (Go-based). Assemble modules (weather, TODO, git changes, calendar, system stats, ticket lists) into a personalized dashboard. Configuration via YAML; AI can be used to generate config examples.
  • v4l2loopback-ctl: CLI to create/manage virtual V4L2 video devices (create device, set capabilities, max resolution, exclusive capture, set fallback image). Demo used ffmpeg streaming into a virtual camera and viewing in VLC — useful for virtual webcams / OBS bridging.
  • Grafana demo: building dashboards that pull metrics from MQTT (e.g., Raspberry Pi & laptop metrics such as load, disk free, memory, uptime). Covered panels, transforms, units, thresholds, and alerts.
