Untitled Linux Show 275

Episode Summary

The hosts covered Linux desktop, enterprise, gaming, browser, security, and development news. A recurring theme was whether better compatibility and management tools could make Linux easier to adopt.

Office Software and Enterprise Linux

• New office suites are targeting familiarity with Microsoft Office. Starling Office is an early, version 0.1 suite for Linux, Windows, and macOS, with word-processing, spreadsheet, and presentation apps and support for DOCX, XLSX, and PPTX. Artcraft’s Wordcraft, Gridcraft, and Deckcraft are open-source Rust projects designed around familiar Office-style interfaces; they are still under development.
• ONLYOFFICE 10 adds an optional, separately installed AI module, currently in beta. It can summarize documents, clean spreadsheet data, find formula errors, generate slides, and draft presentation notes. It supports cloud services and local models.
• Microsoft Defender for Endpoint is available for Linux. This is a paid enterprise product, not the standard consumer Defender app. Its endpoint detection and response system uses an eBPF-based sensor rather than a conventional kernel module, and includes vulnerability-management capabilities. The panel discussed how this could help organizations meet security and compliance requirements for Linux desktops and servers.
• The hosts also considered whether Microsoft might eventually rely more heavily on Linux, while noting that Windows remains useful to Microsoft as a way to keep businesses tied to its broader services.

Linux Gaming

• Steam’s beta client is moving to 64-bit and into a runtime container. Valve says the change should make the client more consistent across distributions. The client uses the Steam Runtime 3 “Sniper” environment, but users still need 32-bit libraries because many games and Proton components depend on them. The beta also has system and graphics requirements, including a Vulkan-capable GPU and support for X11 or Wayland.
• Epic announced EAC Linux V2, a rebuilt Linux implementation of Easy Anti-Cheat, and plans to test it with Fortnite before offering it to other developers. Rather than install a traditional anti-cheat kernel module, it uses existing Linux security features, eBPF programs, and a systemd service. The stated requirements include TPM 2.0, Secure Boot, measured boot, and IOMMU; Steam Deck support was not available yet. The hosts stressed that individual game developers still need to enable support.
• The panel noted that Proton has made a large portion of Windows games playable on Linux, while multiplayer anti-cheat remains an obstacle for some players.

Desktop, Browser, and Security News

• KDE Plasma 6.8 was released alongside discussion of KDE’s 30th anniversary. The hosts also previewed work planned for Plasma 6.9, including improvements to the weather widget and on-screen keyboard.
• Firefox 158 enables JPEG XL support by default. The format supports lossy and lossless compression, transparency, animation, HDR, and progressive image loading; it can also losslessly convert existing JPEGs into smaller JPEG XL files. The discussion noted that lossless decoding can be slower than alternatives, so the format may not be best for every use. The hosts said support had also arrived in the other major browser engines.
• Mozilla introduced Firefox Enterprise, a self-hosted management offering for organizations to control extensions, telemetry, AI features, and other browser policies. At the time discussed, it was initially marketed in several European countries, and Mozilla had not confirmed whether the management console itself was open source. Thunderbird Enterprise was also mentioned as planned.
• AI-assisted Linux kernel development was a major topic. Linus Torvalds had used Claude Code to explore a kernel performance improvement and to understand and restructure difficult code. Testing uncovered several old bugs. Separately, kernel maintainers were discussing a proposal to remove the requirement to label AI-assisted patches; that change was still only proposed.
• The hosts described Pwn Escape, a security flaw found during a sandbox challenge. The reported issue involved deferred checksums and packet fragmentation in the Linux networking stack, which could let a virtual machine access host memory. The problem was fixed upstream before the details were discussed publicly; a follow-up analysis was expected to cover a possible write-based exploit chain.

Hardware and Project Support

• Framework increased its sponsorship of CachyOS from $250 per month to $10,200 per year. The funding is intended to support infrastructure, kernel optimization, packaging, and hardware support. The hosts connected the sponsorship to CachyOS’s popularity among Linux gamers and Framework users.
• The panel briefly discussed NVIDIA’s ARM-based RTX Spark hardware and whether Linux could run on it. They noted that Linux support would depend on bootloader access and hardware-specific support, and did not reach a firm conclusion.

Command-Line Tips

1. Convey: A GTK4 email client forked from Geary, with a simple conversation-based layout. The presenter reported testing it with IMAP and said its advertised Outlook and Microsoft 365 support might require further investigation.
2. psutils: A collection of tools for manipulating PostScript and PDF pages. Examples included placing multiple pages on one sheet, selecting or reordering pages, joining documents, resizing pages, and arranging pages for booklet printing.
3. TShark: The command-line packet-capture tool associated with Wireshark. The host demonstrated capturing traffic and noted that, on Fedora, users may need to join the wireshark group to capture packets without running the tool as root.

No full product review or step-by-step tutorial was presented; the command-line segments were brief practical recommendations and demonstrations.
