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.
