Last week you asked questions of Ubuntu Unleashed author Matthew Helmke, about everything from system D to the future of Ubuntu and Canonical; he's responded, at length. Read on for Matthew's answers.

An anonymous reader writes: With this month's Raspbian OS update, the Debian-based operating system for the Raspberry Pi ships experimental OpenGL driver support. This driver has been developed over the past two years by a former Intel developer with having a completely open and mainline DRM kernel driver and Mesa Gallium driver to open up the Pi as a replacement to the proprietary GPU driver.

New submitter Tenebrousedge writes: Docker container sizes continue a race to the bottom with a couple of environments weighing in at less than 10MB. Following on the heels of this week's story regarding small images based on Alpine Linux, it appears that the official Docker images will be moving from Debian/Ubuntu to Alpine Linux in the near future. How low will they go?

Matthew Helmke (personal blog) is the author of the newly published 11th edition of Ubuntu Unleashed (published by Pearson); this updated edition of the book will cover the OS through Ubuntu's 15.10 and (forthcoming) 16.04 releases. Helmke is also a former Ubuntu Forum administrator, a musician, an entrepreneur, and a long-time Slashdot reader who now leads a "nice quiet life in Iowa." Ask Matthew about what it's like to be a Linux book author and community leader, and his thoughts on Canonical, the goods and bads of modern Linux distributions, and the future of Ubuntu -- especially relevant with the upcoming release of the first Ubuntu-based tablet. (Remember, Matthew isn't responsible for gripes you may have with either Ubuntu or Canonical, but he might have some good solutions to particular problems.) Ask as many questions as you'd like; we just ask that you keep them on-topic, and please stick to one question per post.

A_Mythago writes: The Amnesic Incognito Live System (Tails) has finalized version 2.0, which has several improvements and updates to continue to meet their mission of preserving privacy, anonymity and circumventing censorship without a trace, using a Debian 8.0 custom live distro. More details about Edward Snowden's use of Tails and the distro itself can be found at a previous Slashdot story from 2014.

An anonymous reader writes: In a 10-way Linux distribution battle including OpenSUSE, Debian, Ubuntu, Fedora, and others, one of the fastest out-of-the-box performers was a surprising contender: Intel's Clear Linux Project that's still in its infancy. Clear Linux ships in an optimized form for delivering best performance on x86 hardware with enabling many compiler optimizations by default, highly-tuned software bundles, function multi-versioning for the most performant code functions based upon CPU, AutoFDO for automated feedback-direct optimizations and other performance-driven features. Clear Linux is a rolling-release-inspired distribution that issues new versions a few times a day and is up to version 5700.

An anonymous reader writes: Shortly after the death of Debian founder Ian Murdock, Bruce Perens, who succeeded Murdock as Debian Project Leader in 1996 and was also Murdock's employer for a period of time, claimed very publicly that Murdock died of mental illness, although no evidence has been provided. Without referencing Murdock or Perens, another prominent Debian Developer, Daniel Pocock, has asserted that discussion about who has or had a mental illness is a step too far. To be fair, it sure doesn't sound like Perens was trying to do other than express sympathy in light of a tragic death.

Unknown Lamer writes: It has been confirmed that Debian founder Ian Murdock has died. From the Docker blog: "It is with great sadness that we inform you that Ian Murdock passed away on Monday night. This is a tragic loss for his family, for the Docker community, and the broader open source world; we all mourn his passing. ... Ian helped pioneer the notion of a truly open project and community, embracing open design and open contribution; in fact the formative document of the open source movement itself (the Open Source Definition) was originally a Debian position statement. It is a testament to Ian's commitment to openness and community that there are now more than 1,000 people currently involved in Debian development."

jones_supa writes: Developer Julian Andres Klode has this week made some improvements to significantly increase the speed of incremental updates with Debian GNU/Linux's APT update system. His optimizations have yielded the apt-get program to suddenly yield 10x performance when compared to the old code. These improvements also make APT with PDiff now faster than the default, non-incremental behavior. Beyond the improvements that landed this week, Julian is still exploring other areas for improving APT update performance. More details via his blog post.

prisoninmate writes: Ubuntu Pi Flavour Maker is an open source tool, a shell script that lets anyone port any of the official or unofficial Ubuntu Linux flavors for the Raspberry Pi 2. Ubuntu Pi Flavour Maker is officially supported on the Ubuntu, Ubuntu MATE, Kubuntu, Lubuntu, Xubuntu and Ubuntu GNOME flavors, and uses the traditional apt and dpkg package management systems from Debian GNU/Linux.

prisoninmate writes: A zero-day security flaw was discovered by developers Ismael Ripoll and Hector Marco in the upstream GRUB2 packages. GRUB2 did not correctly handle the backspace key when the bootloader was configured to use password protected authentication, thus allowing a local attacker to bypass GRUB's password protection. Versions from 1.98 (December, 2009) to 2.02 (December, 2015) are affected. At the moment, it looks like only a few distributions received the patched GRUB2 versions, including Ubuntu, Debian (Squeeze LTS only) and Red Hat Enterprise Linux 7.

prisoninmate writes: Google announces that its Google Chrome web browser will no longer be available for 32-bit hardware platforms. Additionally, Google Chrome will no longer be supported on the Ubuntu 12.04 LTS (Precise Pangolin) and Debian GNU/Linux 7 (Wheezy) operating systems. Users are urged to update to the Ubuntu 14.04 LTS (Trusty Tahr) release and Debian GNU/Linux 8 (Jessie) respectively. Google will continue to support the 32-bit build configurations for those who want to build the open-source Chromium web browser on various Linux kernel-based operating systems. Reader SmartAboutThings writes, on a similar note, that: Microsoft is tolling the death knell for Internet Explorer with an announcement that it will end support for all older versions next year. Microsoft says that all versions older than the latest one will no longer be supported starting Jan. 12, 2016. After this date, Microsoft will no longer provide security updates or technical support for older Internet Explorer versions. Furthermore, Internet Explorer 11 will be the last version of Internet Explorer as Microsoft shifts its focus on its next web browser, Microsoft Edge.

New submitter yeupou writes: Early this year, David Edmundson from KDE, concluded that "In many cases [systemd] allows us to throw away large amounts of code whilst at the same time providing a better user experience. Adding it [systemd] as an optional extra defeats the main benefit". A perfectly sensible explanation. But, then, one might wonder to which point KDE would remain usable without systemd?

Recently, on one Devuan box, I noticed that KDE power management (Powerdevil) no longer supported suspend and hibernate. Since pm-utils was still there, for a while, I resorted to call pm-suspend directly, hoping it would get fixed at some point. But it did not. So I wrote a report myself. I was not expecting much. But neither was I expecting it to be immediately marked as RESOLVED and DOWNSTREAM, with a comment accusing the "Debian fork" I'm using to "ripe out" systemd without "coming with any of the supported solutions Plasma provides". I searched beforehand about the issue so I knew that the problem also occurred on some other Debian-based systems and that the bug seemed entirely tied to upower, an upstream software used by Powerdevil. So if anything, at least this bug should have been marked as UPSTREAM.

While no one dares (yet) to claim to write software only for systemd based operating system, it is obvious that it is now getting quite hard to get support otherwise. At the same time, bricks that worked for years without now just get ruined, since, as pointed out by Edmunson, adding systemd as "optional extra defeats its main benefit". So, is it likely that we'll still have in 2016 a modern desktop environment, without recent regressions, running without systemd?

An anonymous reader writes: Today marks three years since Valve's Steam client went into beta on Linux. In that time over 1,600 games have become natively available for Linux. Going beyond having many new Linux games, Phoronix recaps, "we've seen Valve make significant investments into the open-source graphics stack and other areas of Linux (in part through their sponsorship of Collabora and LunarG). Valve developers are significantly pushing SDL2. We've seen more mainstream interest in Linux gaming, and Valve has been heavily involved in the creation of the Vulkan graphics API. They have given away their entire game collection to the Mesa/Ubuntu/Debian upstream developers, and much more." The three-year anniversary is coincidentally just days before the release of Steam Machines.

iamacat writes: Back in 90s, we used Linux not only because of open source, but also for innovative features not found in commercial operating systems — better multitasking, network power features like slirp and masquerading, free developer tools for many languages. Nowadays OSX and Windows caught up in these areas and mainstream distros like Ubuntu dumbed down in default configuration. So where to go for active innovation like 3D/VR desktop, artificial intelligence, drag and drop ability to mash up UI of multiple apps or just drastically better performance? Something maybe rough around the edges but usable and exciting enough to use as daily desktop?

An anonymous reader writes: A 22-way AMD Radeon vs. NVIDIA GeForce graphics card comparison on SteamOS 2.0 "Brewmaster" was carried out with one month to go until Steam Machines begin to ship. The article looks at the OpenGL performance of this Debian-based Linux distribution as well as the power/performance efficiency, thermal efficiency, and value of the entire line-up. The results make it pretty clear why the current range of Steam Machines with SteamOS all ship with NVIDIA graphics.

basscomm writes: For years (as seen on Slashdot) the Linux Standard Base has been developed as an attempt to reduce the differences between Linux distributions in an effort significant effort. However, Debian Linux has announced that they are dropping support for the Linux Standard Base due to a lack of interest.

From the article: "If [Raboud's] initial comments about lack of interest in LSB were not evidence enough, a full three months then went by with no one offering any support for maintaining the LSB-compliance packages and two terse votes in favor of dropping them. Consequently, on September 17, Raboud announced that he had gutted the src:lsb package (leaving just lsb-base and lsb-release as described) and uploaded it to the "unstable" archive. That minimalist set of tools will allow an interested user to start up the next Debian release and query whether or not it is LSB-compliant—and the answer will be 'no.'"

The Free Software Foundation will be celebrating its 30th anniversary on Oct. 3rd. Recently, you had a chance to ask its founder Richard Stallman about GNU/Linux, free software, and other issues of public concern. Below you'll find his answers to your questions. Learn more about how you can join the FSF here, and help fight the good fight.

An anonymous reader writes: Debian's Jérémy Bobbio, also known as Lunar, spoke at the Chaos Communication Camp about the distribution's efforts to reassert trustworthiness for open source binaries after it was brought into question by various intelligence agencies. Debian is "working to bring reproducible builds to all of its more than 22,000 software packages," and is pushing the rest of the community to do the same. Lunar said, "The idea is to get reasonable confidence that a given binary was indeed produced by the source. We want anyone to be able to produce identical binaries from a given source (PDF)."

Here is Lunar's overview of how this works: "First you need to get the build to output the same bytes for a given version. But others also must to be able to set up a close enough build environment with similar enough software to perform the build. And for them to set it up, this environment needs to be specified somehow. Finally, you need to think about how rebuilds are performed and how the results are checked."

mescobal writes: A new release of the Trinity Desktop Environment (TDE) is out. TDE is "a computer desktop environment for Unix-like operating systems with a primary goal of retaining the function and form of traditional desktop computers" which translates into a fully functional KDE 3 style Desktop. Something is missing in the new generation of desktop environments, since some people (perhaps more than "some") feel at home with Gnome 2 or KDE i3. They have repositories for Debian and Ubuntu-based distros. I'm now using it on Ubuntu 15.04, amazed about how well-planned things were in the previous generation of DE. We may have gained some things with Gnome 3 and Plasma 5, but we lost a lot of good features too. TDE brings them back.
