Debian-Based Q4OS Linux Operating System for Raspberry Pi Goes Stable

Filed under
Linux
Debian

Q4OS emphasizes the Trinity Desktop Environment (TDE), which continues the legacy of the old KDE 3.5 desktop. The latest release, Q4OS 2.5, was available only for 64-bit (x86_64) and 32-bit (i686 PAE) hardware architectures, but now it can also be installed on ARM hardware like the Raspberry Pi, Pine64, and Pinebook.

"Q4OS on Raspberry Pi performs at lightning speed due to its exceptionally low hardware requirements," say the devs in the announcement. "All the native Q4OS features, for example "Desktop profiler" and "Setup tool," are available and fully functional within the Raspberry Pi Q4OS edition."

  • How to install Linux apps on your Chromebook

    Chromebooks are great because they're simple: there's a lot you can get done with web services without exposing yourself to the troubles and security issues that plague more complex platforms.

    But if you need to do a bit more with your Chromebook, you have a few options. Most Chromebooks these days allow you to install apps from the Google Play Store, which should fill most productivity gaps. If not, you'll soon have one more option: installing Linux apps. To be clear, you've been able to install Linux apps on Chromebooks for years because Chrome OS is Linux. But, it's about to get much easier.

  • Top 5 Features Still Missing From Chrome OS

    Google’s Chrome OS gets a lot of things right, and the platform has evolved considerably over the years. Not only does it offer an always up-to-date version of the Chrome browser, but there are also Android apps, stylus input, and even Linux support on some devices. However, Chrome OS is far from perfect. You have to make compromises if you choose to live with a Chromebook, but you shouldn’t have to make quite this many. Here are the top five things Google should fix.

  • Walmart's selling an all-aluminum Chromebook with a comfy keyboard for just $220

    If you’re not considering a Chromebook when you're shopping for a notebook, you’re doing it wrong. Google's low-cost laptops are typically light, fast, secure, and have almost everything you need for remote work a.k.a. the Internet. Today, you can get in on the action for a great price. Walmart is selling the Acer Chromebook 14 (CB3-431-C6ZB) for $220. That’s about $30 to $40 cheaper than you’d usually pay for this laptop.

LWN on Linux Kernel: Scheduler, Speck, and WireGuard

Filed under
Linux
  • Scheduler utilization clamping

    Once upon a time, the only way to control how the kernel's CPU scheduler treated any given process was to adjust that process's priority. Priorities are no longer enough to fully control CPU scheduling, though, especially when power-management concerns are taken into account. The utilization clamping patch set from Patrick Bellasi is the latest in a series of attempts to allow user space to tell the scheduler more about any specific process's needs.

    Contemporary CPU schedulers have a number of decisions to make at any given time. They must, of course, pick the process that will be allowed to execute in each CPU on the system, distributing processes across those CPUs to keep the system as a whole in an optimal state of busyness. Increasingly, the scheduler is also involved in power management — ensuring that the CPUs do not burn more energy than they have to. Filling that role requires placing each process on a CPU that is appropriate for that process's needs; modern systems often have more than one type of CPU available. The scheduler must also pick an appropriate operating power point — frequency and voltage — for each CPU to enable it to run the workload in a timely manner while minimizing energy consumption.

  • Reconsidering Speck

    The Speck cipher is geared toward good performance in software, which makes it attractive for smaller, often embedded, systems with underpowered CPUs that lack hardware crypto acceleration. But it also comes from the US National Security Agency (NSA), which worries lots of people outside the US—and, in truth, a fair number of US citizens as well. The NSA has earned a reputation for promulgating various types of cryptographic algorithms with dubious properties. While the technical arguments against Speck, which is a fairly simple and straightforward algorithm with little room for backdoors, have not been all that compelling, the political arguments are potent—to the point where it is being dropped by the main proponent for including it in the kernel.

  • WireGuarding the mainline

    The WireGuard VPN tunnel has been under development — and attracting attention — for a few years now; LWN ran a review of it in March. While WireGuard can be found in a number of distribution repositories, it is not yet shipped with the mainline kernel because its author, Jason Donenfeld, hasn't gotten around to proposing it for upstreaming. That changed on on July 31, when Donenfeld posted WireGuard for review. Getting WireGuard itself into the mainline would probably not be all that hard; merging some of the support code it depends on could be another story, though.

    WireGuard implements a simple tunneling protocol allowing network traffic to be routed through a virtual private network provider. It has been developed with an eye toward smallness, ease of verification, and performance, rather than large numbers of features. It is, according to the patch posting, "used by some massive companies pushing enormous amounts of traffic". Some effort has gone into making WireGuard widely available, an effort that has helped to create a significant user community. But the ultimate way to make this kind of software widely available is to get it into everybody's kernel; that requires upstreaming.

A 'Bridge' for GNU/Linux Games

Gaming
  • Valve seems to be working on tools to get Windows games running on Linux

    Valve appears to be working on a set of "compatibility tools," called Steam Play, that would allow at least some Windows-based titles to run on Linux-based SteamOS systems.

    Yesterday, Reddit users noticed that Steam's GUI files (as captured by SteamDB's Steam Tracker) include a hidden section with unused text related to the unannounced Steam Play system. According to that text, "Steam Play will automatically install compatibility tools that allow you to play games from your library that were built for other operating systems."

  • Valve could be working on compatibility tools to make gaming on Linux easier than ever

    Something to look forward to: Gaming on Linux has never been the ideal experience, and the lack of AAA game compatibility is one of the main reasons for this. That's where Valve comes in, apparently - the company seems to be quietly working on a compatibility tool of its own, called "Steam Play."

    It seems Valve could be taking another shot at bringing Linux to the forefront of PC gaming if recently-discovered Steam GUI files are anything to go by.

    Curious Reddit users dug into Steam database files obtained by Steam Tracker. Recent updates to the database include numerous hints at something called "Steam Play," which is beginning to sound like a compatibility tool of sorts.

  • Steam may be getting tools that will enable Windows games to run in Linux

    Valve announced the Linux-based SteamOS in 2013, just prior to the reveal of the vaguely console-like Steam Machine PCs. It was a big, bold move that ultimately petered out: Valve ditched the Steam Machines section of its website in April, aalthough you can still hit it directly if you know the URL.

  • Looks like Steam’s getting built-in tools to run Windows games on Linux

    A few lines of code uncovered in Steam suggest that Valve is working on compatibility tools to allow users to play games regardless of operating system. Put another way, Steam’s going to let you run Windows games on Mac and Linux with a set of software built directly into the client.

    Uncovered strings all come under the “Steam_Settings_Compat” header, and all reference back to Steam Play. That’s currently the moniker Valve used to distinguish games that come as a single purchase playable across Windows, Mac, and Linux, but the strings suggest a new definition on the way.

  • Rumour: Valve May Be Adding Windows Steam Game Compatibility to Linux

    In a very interesting move, sleuths over at GamingOnLinux appear to unearthed evidence that Valve is experimenting with tools that could allow Windows Steam games to be playable on Linux operating systems.

    Up until this point, a game has to be specifically developed for Linux in order to be compatible with Unix-based operating systems. There are workarounds available right now, but it’s notoriously unreliable and a major hassle to get sorted.

    However, updates posted to the Steam Database github indicates Valve is at least testing an automatic method for running Windows games on Linux. Picking through the github notes, the tool appears to be called ‘Steam Play’, which the compatibility info says “Steam Play will automatically install compatibility tools that allow you to play games from your library that were built for other operating systems.”

GNOME: NVMe Firmware and GSConnect

  • Richard Hughes: NVMe Firmware: I Need Your Data
    In a recent Google Plus post I asked what kind of hardware was most interesting to be focusing on next. UEFI updating is now working well with a large number of vendors, and the LVFS “onboarding” process is well established now. On that topic we’ll hopefully have some more announcements soon. Anyway, back to the topic in hand: The overwhelming result from the poll was that people wanted NVMe hardware supported, so that you can trivially update the firmware of your SSD. Firmware updates for SSDs are important, as most either address data consistency issues or provide nice performance fixes.
  • Gnome Shell Android Integration Extension GSConnect V12 Released
    GSConnect v12 was released yesterday with changes like more resilient sshfs connections (which should make browsing your Android device from the desktop more reliable), fixed extension icon alignment, along with other improvements. GSConnect is a Gnome Shell extension that integrates your Android device(s) with the desktop. The tool makes use of the KDE Connect protocol but without using any KDE dependencies, keeping your desktop clean of unwanted packages.
  • Linux Release Roundup: Communitheme, Cantata & VS Code
    GSconnect is a magical GNOME extension that lets your Android phone integrate with your Linux desktop.

Anyway, a new version of GSconnect popped out this week. GSconnect v12 adds a nifty new features or two, as well as a few fixes here, and a few UI tweaks there.

Red Hat Leftovers

  • Red Hat Advances Container Storage
    Red Hat has moved to make storage a standard element of a container platform with the release of version 3.1 of Red Hat OpenShift Container Storage (OCS), previously known as Red Hat Container Native Storage. Irshad Raihan, senior manager for product marketing for Red Hat Storage, says Red Hat decided to rebrand its container storage offering to better reflect its tight integration with the Red Hat OpenShift platform. In addition, the term “container native” continues to lose relevance given all the different flavors of container storage that now exist, adds Raihan. The latest version of the container storage software from Red Hat adds arbiter volume support to enable high availability with efficient storage utilization and better performance, enhanced storage monitoring and configuration via the Red Hat implementation of the Prometheus container monitoring framework, and block-backed persistent volumes (PVs) that can be applied to both general application workloads and Red Hat OpenShift Container Platform (OCP) infrastructure workloads. Support for PVs is especially critical because to in the case of Red Hat OCS organizations can deploy more than 1,000 PVs per cluster, which helps to reduce cluster sprawl within the IT environment, says Raihan.

  • Mixing software development roles produces great results
    Most open source communities don’t have a lot of formal roles. There are certainly people who help with sysadmin tasks, testing, writing documentation, and translating or developing code. But people in open source communities typically move among different roles, often fulfilling several at once. In contrast, team members at most traditional companies have defined roles, working on documentation, support, QA, and in other areas. Why do open source communities take a shared-role approach, and more importantly, how does this way of collaborating affect products and customers? Nextcloud has adopted this community-style practice of mixing roles, and we see large benefits for our customers and our users.
  • FOSS Project Spotlight: SIT (Serverless Information Tracker)
    In the past decade or so, we've learned to equate the ability to collaborate with the need to be online. The advent of SaaS clearly marked the departure from a decentralized collaboration model to a heavily centralized one. While on the surface this is a very convenient delivery model, it simply doesn't fit a number of scenarios well. As somebody once said, "you can't FTP to Mars", but we don't need to go as far. There are plenty of use cases here on Earth that are less than perfectly suited for this "online world". Lower power chips and sensors, vessel/offshore collaboration, disaster recovery, remote areas, sporadically reshaping groups—all these make use of central online services a challenge. Another challenge with centralization is somewhat less thought of—building software that can handle a lot of concurrent users and that stores and processes a lot of information and never goes down is challenging and expensive, and we, as consumers, pay dearly for that effort. And not least important, software in the cloud removes our ability to adapt it perfectly for use cases beyond its owner's vision, scope and profitability considerations. Convenience isn't free, and this goes way beyond the price tag.

  • ASAN And LSAN Work In rr
    AddressSanitizer has worked in rr for a while. I just found that LeakSanitizer wasn't working and landed a fix for that. This means you can record an ASAN build and if there's an ASAN error, or LSAN finds a leak, you can replay it in rr knowing the exact addresses of the data that leaked — along with the usual rr goodness of reverse execution, watchpoints, etc. Well, hopefully. Report an issue if you find more problems.
  • Oracle Open-Sources GraphPipe to Support ML Development
    Oracle on Wednesday announced that it has open-sourced GraphPipe to enhance machine learning applications. The project's goal is to improve deployment results for machine learning models, noted Project Leader Vish Abrams. That process includes creating an open standard. The company has a questionable relationship with open source developers, so its decision to open-source GraphPipe might not receive a flood of interest. Oracle hopes developers will rally behind the project to simplify and standardize the deployment of machine learning models. GraphPipe consists of a set of libraries and tools for following a deployment standard.
  • OERu makes a college education affordable
    Open, higher education courses are a boon to adults who don’t have the time, money, or confidence to enroll in traditional college courses but want to further their education for work or personal satisfaction.

It allows people to take courses assembled by accredited colleges and universities for free, using open textbooks, and pay for assessment only when (and if) they want to apply for formal academic credit. I spoke with Dave Lane, open source technologist at the Open Education Resource Foundation, which is OERu’s parent organization, to learn more about the program. The OER Foundation is a nonprofit organization hosted by Otago Polytechnic in Dunedin, New Zealand. It partners with organizations around the globe to provide leadership, networking, and support to help advance open education principles.

It once again follows our (and Conrad's) bi-monthly release schedule. Conrad started with a new 9.100.* series a few days ago. I ran reverse-depends checks and found an issue which he promptly addressed; CRAN found another which he also very promptly addressed. It remains a true pleasure to work with such experienced professionals as Conrad (with whom I finally had a beer around the recent useR! in his home town) and of course the CRAN team whose superb package repository truly is the bedrock of the R community.
