Linux PC Maker System76 Plans To Design And Manufacture Its Own Hardware (liliputing.com) 101

An anonymous reader quotes Liliputing: System76 is one of only a handful of PC vendors that exclusively sells computers with Linux-based software. Up until now, that's meant the company has chosen hardware that it could guarantee would work well with custom firmware and the Ubuntu Linux operating system... Starting in 2018 though, you may be able to buy a System76 computer that was designed and built in-house... CAD files for System76 computers will be open source, allowing anyone with the appropriate skills and equipment to build or modify their own cases based on the company's designs.
"We're prototyping with acrylic and moving to metal soon," the company says in a blog post, adding "Our first in-house designed and manufactured desktops will ship next year. Laptops are more complex and will follow much later."

Ubuntu Is Switching to Wayland (omgubuntu.co.uk) 226

An anonymous reader shares a report: Ubuntu is to ship Wayland in place of X.Org Server by default. Mir, Canonical's home-spun alternative to Wayland, had been billed as the future of Ubuntu's convergence play. But both Unity 8 the convergence dream was recently put out to pasture, meaning this decision was widely expected. It's highly likely that the traditional X.Org Server will, as on Fedora, be included on the disc and accessible from whichever login screen Ubuntu devs opt to use in ubuntu 17.10 onwards. This session will be useful for users whose system experience issues running on Wayland, or who need features and driver support that is only present in the legacy X.Org server session.

FriendELEC Releases $40 NanoPi K2 Board That Competes With ODROID-C2, Raspberry Pi 3 (cnx-software.com) 80

DeathByLlama writes: The single board computer market, broken wide-open just a few years ago by the Raspberry Pi Foundation, continues to flourish today as FriendELEC releases their $40 NanoPi K2 board. This SBC packs a 1.5 GHz 64-bit quad core Amlogic S905 processor, and paired with 2GB of DDR3 RAM and the Mali-450MP GPU, it is able to stream 4K at 60 FPS. Add in gigabit ethernet, onboard Wi-Fi, Bluetooth, IR (and a remote!), eMMC compatibility, a familiar GPIO header, and a $40 price tag, and you end up with some stiff competition for other market leaders like Hardkernel's ODROID-C2 and Raspberry Pi's flagship Pi 3. The release is clearly in early phases with Ubuntu images and house-sold eMMC modules still on their way. It's amazing to see such strong competition in this market -- and with so many sub-$100, incredibly capable SBC options, which will choose?

Ubuntu 17.04 'Zesty Zapus', Featuring Unity, Now Available To Download (betanews.com) 83

Brian Fagioli, writing for BetaNews: Ubuntu 17.04 "Zesty Zapus" is available for download. No, this is not an Alpha or Beta, but an official stable version of the Linux-based operating system. Unfortunately, the release is a bit tainted -- it uses Unity as the official desktop environment, which Canonical has announced will be killed. Not to mention, there has been some controversy regarding some comments by Ubuntu founder Mark Shuttleworth. Just yesterday, the CEO of Canonical announced she is leaving the position. With all of the aforementioned controversy and chaos, it is understandably hard to get too excited for "Zesty Zapus," especially as this is not a long term support version. With that said, if you are an existing Ubuntu user that likes Unity, this is certainly a worthwhile upgrade if you are OK with the shorter support. Unity may no longer have a future, but version 7 will continue to be supported -- for a while, at least.

Dozens Of Canonical Employees Resign As Ubuntu Switches To GNOME, Shuttleworth Returns As CEO (theregister.co.uk) 191

Alexander J Martin, reporting for The Register: More than 80 Canonical workers are facing the axe as founder Mark Shuttleworth has taken back the role of chief executive officer. The number, revealed today by The Reg, comes as Shuttleworth assumed the position from CEO of eight years Jane Silber, previously chief operating officer. The Reg has learned 31 or more staffers have already left the Ubuntu Linux maker ahead of Shuttleworth's rise, with at least 26 others now on formal notice and uncertainty surrounding the remainder. One individual has resigned while others, particularly in parts of the world with more stringent labour laws (such as the UK), are being left in the dark. The details come after The Reg revealed plans for the cuts as a commercial get-fit programme instituted by Shuttleworth. The Canonical founder is cutting numbers after an external assessment of his company by potential new financial backers found overstaffing and that projects lacked focus.

Canonical Founder Criticizes Free Software Developers Who 'Hate On Whatever's Mainstream' (google.com) 374

Canonical Founder Mark Shuttleworth said Saturday that "I came to be disgusted with the hate" on Canonical's display server Mir, saying it "changed my opinion of the free software community." After announcing his company was abandoning Unity for GNOME, Shuttleworth posted a gracious thank-you note to the Unity community Friday on Google Plus. But on Saturday, he added a sharper comment: "I used to think that it was a privilege to serve people who also loved the idea of service, but now I think many members of the free software community are just deeply anti-social types who love to hate on whatever is mainstream. When Windows was mainstream they hated on it. Rationally, Windows does many things well and deserves respect for those. And when Canonical went mainstream, it became the focus of irrational hatred too. The very same muppets would write about how terrible it was that IOS/Android had no competition and then how terrible it was that Canonical was investing in (free software!) compositing and convergence. Fuck that shit."
The comment begins by saying "The whole Mir hate-fest boggled my mind - it's free software that does something invisible really well. It became a political topic as irrational as climate change or gun control, where being on one side or the other was a sign of tribal allegiance. We have a problem in the community when people choose to hate free software instead of loving that someone cares enough to take their life's work and make it freely available."

Canonical Founder Talks About Ubuntu Desktop Switching From Unity To GNOME, And Focus On Cloud (google.com) 80

Canonical founder Mark Shuttleworth on Friday talked about the move to switch Ubuntu's desktop user interface from Unity to GNOME, and putting a stop to development of Ubuntu software for phones and tablet: I would like to thank all of you for your spirit and intellect and energy in the Unity8 adventure. [...] Many elements of the code in the Ubuntu Phone project continue -- snaps grew out of our desire to ship apps reliably and efficiently and securely, the unity8 code itself will continue to be useful for UBports and other projects. And the ideas that we have pushed for are now spreading too. Finally, I should celebrate that Ubuntu consists of so many overlapping visions of personal computing, that we have the ability to move quickly to support the Ubuntu GNOME community with all the resources of Canonical to focus on stability, upgrades, integration and experience. That's only possible because of the diversity of shells in the Ubuntu family, and I am proud of all of our work across that full range.

GNOME Dev Schaller Assures Ubuntu Users the Move To Step Away From Unity Will Bring Consistency Across Linux Distros (gnome.org) 104

Earlier this week, Canonical announced that Ubuntu will be ditching Unity as the default user interface on desktops to go back to GNOME next year. The company also said that it will be ending development of Ubuntu software for phones and tablets, in what is a push to focus on cloud. In a blog post, Christian Schaller, a developer on Fedora and GNOME (and Senior Software Engineering Manager at Red Hat), offered some assurance to the community that this is the right move in the grand scheme of things. He writes on an official blog post: We look forward to keep working with great Canonical and Ubuntu people like Allison Lortie and Robert Ancell on projects of shared interest around GNOME, Wayland and hopefully Flatpak. It is worth mentioning that even as we [have] been competing with Unity and Ubuntu, we have also been collaborating with them, most recently on [the] integration of features they wanted from GNOME Software such as user reviews. Of course now sharing a bigger set of technologies collaboration will be even easier. I am personally happy to see this convergence of efforts happening because I have -- for a long time -- felt that the general level of investment in the Linux desktop has not been great enough to justify the plethora of Linux desktops out there. Now having reached a position where Canonical, Endless, Red Hat and Suse again share one desktop technology stack and along with consulting companies such as Centricular, CodeThink, Collabora and Igalia helping push parts of the stack forward, we are at least all pulling in the same direction. This change should also make life easier for ISV who now have a more clear target if they want to try to integrate their UI with the Linux desktop as 'the linux desktop' becomes a more meaningful term with this change.

Canonical Killing Unity For Ubuntu Linux, Will Switch To the Superior GNOME (betanews.com) 386

Reader BrianFagioli writes: Today, the company admits that it is throwing in the towel on Unity, as well as its vision for convergence with devices like phones and tablets. Starting with Ubuntu 18.04, the wonderful GNOME will once again become the default desktop environment! "We are wrapping up an excellent quarter and an excellent year for the company, with performance in many teams and products that we can be proud of. As we head into the new fiscal year, it's appropriate to reassess each of our initiatives. I'm writing to let you know that we will end our investment in Unity8, the phone and convergence shell. We will shift our default Ubuntu desktop back to GNOME for Ubuntu 18.04 LTS," says Mark Shuttleworth, Founder of Ubuntu and Canonical.

Ubuntu Linux 17.04 'Zesty Zapus' Final Beta Now Available For Download (betanews.com) 113

BrianFagioli writes: The final beta of Ubuntu 17.04 'Zesty Zapus' became available for download Thursday. While it is never a good idea to run pre-release software on production machines, Canonical is claiming that it should be largely bug free at this point. In other words, if you understand the risks, it should be a fairly safe. Home users aside, this is a good opportunity for administrators to conduct testing prior to the official release next month.

"The Ubuntu team is pleased to announce the final beta release of the Ubuntu 17.04 Desktop, Server, and Cloud products. Codenamed 'Zesty Zapus', 17.04 continues Ubuntu's proud tradition of integrating the latest and greatest open source technologies into a high-quality, easy-to-use Linux distribution," says Adam Conrad, Canonical. "The team has been hard at work through this cycle, introducing new features and fixing bugs."

Canonical Helps Launch A Snap Store For The Orange Pi Community (ubuntu.com) 55

"Developers can distribute their applications packaged as snaps to Orange Pi owners," explains a new blog post from Canonical, bragging that "hackers and tinkerers can install complex IoT and server projects in seconds." An anonymous reader quotes Ubuntu's Insights blog: Orange Pi maker Shenzhen Xunlong Software Co. Ltd is launching an app store in partnership with Canonical to foster an active community of developers and users. Through this app store, developers gain a simple mechanism to share their applications, projects and scripts between themselves and with the wider Orange Pi community...

With snaps developers can distribute their application in a secure, confined package bundled with all its dependencies, so users can install applications that could take half an hour to install in just a few seconds. The Orange Pi App Store uses the whitelabel app store offering from Canonical, which lets them distribute applications to the Orange Pi community under its own brand. The store is a place for developers to share their Orange Pi specific applications. It also benefits from the wealth of applications available in the Ubuntu snap store, also available through the store.

Are there any Slashdot readers who are actually using snaps? Or -- for that matter -- are there any Slashdot readers developing with the Orange Pi?

Edge, VMWare, Safari, And Ubuntu Linux Hacked at Pwn2Own 2017 (trendmicro.com) 83

The 10th annual Pwn2Own hacking competition ended Friday in Vancouver. Some of the highlights:
  • Ars Technica reports one team "compromised Microsoft's heavily fortified Edge browser in a way that escapes a VMware Workstation virtual machine it runs in... by exploiting a heap overflow bug in Edge, a type confusion flaw in the Windows kernel and an uninitialized buffer vulnerability in VMware."
  • Digital Trends reports "Samuel Grob and Niklas Baumstark used a number of logic bugs to exploit the Safari browser and eventually take root control of the MacOS on a MacBook Pro, [and] impressed onlookers even more by adding a custom message to the Touch Bar which read: "pwned by niklasb and saelo."
  • Ubuntu 16.10 Linux was also successfully attacked by exploiting a flaw in the Linux 4.8 kernel, "triggered by a researcher who only had basic user access but was able to elevate privileges with the vulnerability to become the root administrative account user..." reports eWeek. "Chaitin Security Research Lab didn't stop after successfully exploiting Ubuntu. It was also able to successfully demonstrate a chain of six bugs in Apple Safari, gaining root access on macOS."
  • Another attacker "leveraged two separate use-after-free bugs in Microsoft Edge and then escalated to SYSTEM using a buffer overflow in the Windows kernel."

None of the attendees registered to attempt an attack on the Apache Web Server on Ubuntu 16.10 Linux, according to eWeek, but the contest's blog reports that "We saw a record 51 bugs come through the program. We paid contestants $833,000 USD in addition to the dozen laptops we handed out to winners. And, we awarded a total of 196 Master of Pwn points."

Firefox Goes PulseAudio Only, Leaves ALSA Users With No Sound (omgubuntu.co.uk) 322

An anonymous reader shares a report: If you're a Linux user who upgraded to Firefox 52 only to find that the browser no longer plays sound, you're not alone. Firefox 52 saw release last week and it makes PulseAudio a hard dependency -- meaning ALSA only desktops are no longer supported. Ubuntu uses PulseAudio by default (as most modern Linux distributions do) so the switch won't affect most -- but some Linux users and distros do prefer, for various reasons, to use ALSA, which is part of the Linux kernel. Lubuntu 16.04 LTS is one of the distros that use ALSA by default. Lubuntu users who upgraded to Firefox 52 through the regular update channel were, without warning, left with a web browser that plays no sound. Lubuntu 16.10 users are not affected as the distro switched to PulseAudio.

Canonical Preps Security Lifeboat, Yells: Ubuntu 12.04 Hold-Outs, Get In (theregister.co.uk) 88

Gavin Clarke, writing for The Register: Canonical is extending the deadline for security updates for paying users of its five-year-old Ubuntu 12.04 LTS -- a first. Ubuntu 12.04 LTS will become the first Long Term Support release of Canonical's Linux to get Extended Security Maintenance (ESM). There are six LTS editions. All others have been end-of-lifed -- and given no security reprieve. LTS editions of Ubuntu Linux are released every two years. Desktop support runs for three years and the server edition receives security patches and updates for a period of five years. Security updates for 12.04 were scheduled to run out on April 28, 2017 but that now won't happen for those on Canonical's Ubuntu Advantage programme. They'll now receive important security fixes for the kernel and "most essential" userspace packages on their servers running 12.04. In what's shaping up to be Canonical's Windows XP moment over at Microsoft, the Linux spinner rolled out the lifeline because customers are clinging to 12.04.

Dell Doubles Down On High-End Ubuntu Linux Laptops (zdnet.com) 128

Dell became the first major OEM to offer a laptop with Linux pre-installed in it in 2007. Ten years later, the company says it is more committed than ever to offering Linux-powered machines to users. From a report on ZDNet: The best known of these is the Dell XPS 13 developer edition, but it's not the only Linux laptop Dell offers. In a blog post, Barton George, senior principal engineer at Dell's Office of the CTO, announced "the next generation of our Ubuntu-based Precision mobile workstation line." All of these systems boast Ubuntu 16.04 long-term support (LTS), 7th generation Intel Core or Intel Xeon processors, and Thunderbolt 3, AKA 40 Gigabit per second (Gbps) USB-C, ports. As the Xeon processor option shows, these are top-of-the-line laptops for professionals. It took longer than expected for Dell to get this new set of five Ubuntu-powered Precision mobile workstations out the door. The Precision 5520 and 3520 are now available. The 3520, the entry-level workstation, starts with an Intel Core 2.5GHz i5-7300HQ Quad Core processor with Intel HD Graphics 630. From there, you can upgrade it all the way to an Intel Core Xeon 3 GHz E3-1505M v6 processor with Nvidia Quadro M62 graphics.

Ask Slashdot: What Would Happen If All Software Ran On All Platforms? 383

Slashdot reader dryriver writes: We live in a computing world where the OS you use -- Windows, OS X, Linux, Android, iOS, others -- often determines what software can and cannot be run on a given electronic device. (Let us pretend for a moment that emulators and other options don't exist). What if -- magically -- such a thing as as Universally Compatible Software Application were possible. Software, in other words, that is magically capable of running on any electronic device equipped with enough CPU, GPU and memory capacity to run the software in a usable way.

Example: 3D CAD software that runs on Windows 14, Playstation 7, an Android Smartphone, Nintendo's latest handheld gaming device and an Ubuntu PC in exactly the same way with no compatibility problems whatsoever occurring. What would and would not change in such a computing world?

He also asks an even more important question: will this ever be possible or feasible from a technical standpoint? So leave your best answers in the comments. Will it ever be possible to run all software on all platforms -- and what would happen if we could?

Linux Kernel 4.10 Officially Released With Virtual GPU Support (softpedia.com) 90

"Linus Torvalds announced today the general availability of the Linux 4.10 kernel series, which add a great number of improvements, new security features, and support for the newest hardware components," writes Softpedia. prisoninmate quotes their report: Linux kernel 4.10 has been in development for the past seven weeks, during which it received a total of seven Release Candidate snapshots that implemented all the changes that you'll soon be able to enjoy on your favorite Linux-based operating system... Prominent new features include virtual GPU (Graphics Processing Unit) support, new "perf c2c" tool that can be used for analysis of cacheline contention on NUMA systems, support for the L2/L3 caches of Intel processors (Intel Cache Allocation Technology), eBPF hooks for cgroups, hybrid block polling, and better writeback management. A new "perf sched timehist" feature has been added in Linux kernel 4.10 to provide detailed history of task scheduling, and there's experimental writeback cache and FAILFAST support for MD RAID5... Ubuntu 17.04 (Zesty Zapus) could be the first stable OS to ship with Linux 4.10.
It required 13,000 commits, plus over 1,200 merges, Linus wrote in the announcement, adding "On the whole, 4.10 didn't end up as small as it initially looked."

System76 Refreshes Ubuntu Linux Laptops With Intel Kaby Lake, NVIDIA GTX 10 Series, and 4K (betanews.com) 126

Brian Fagioli, writing for BetaNews: System76 is refreshing three of its laptops with some high-end parts. The Oryx Pro, Serval WS, and Bonobo WS are now all equipped with 7th generation Intel Kaby Lake processors. In addition, all three can be had with 4K displays and NVIDIA GTX 10 series graphics too. While the Oryx Pro already had the option of 4K and GTX 10, it is the 7th gen Intel chips that are new to it. In fact, all of the company's laptops now come with Kaby Lake standard. The computer seller throws some shade at Apple by saying, "The HiDPI displays that ship on the laptops have 3.1 million more pixels than Apple's 'Retina' displays, enabling sharper text, 4K video, and higher res gaming. Beyond that, the displays give video and photo professionals the ability to work more easily with higher resolution multimedia."

LinuxQuestions Users Choose Their Favorite Distro: Slackware (zdnet.com) 145

ZDNet summarizes some of the surprises in this year's poll on LinuxQuestions, "one of the largest Linux groups with 550,000 member". An anonymous reader quotes their report: The winner for the most popular desktop distribution? Slackware...! Yes, one of the oldest of Linux distributions won with just over 16% of the vote. If that sounds a little odd, it is. On DistroWatch, a site that covers Linux distributions like paint, the top Linux desktop distros are Mint, Debian, Ubuntu, openSUSE, and Manjaro. Slackware comes in 28th place... With more than double the votes for any category, it appears there was vote-stuffing by Slackware fans... The mobile operating system race was a runaway for Android, with over 68% of the vote. Second place went to CyanogenMod, an Android clone, which recently went out of business...

Linux users love to debate about desktop environments. KDE Plasma Desktop took first by a hair's breadth over the popular lightweight Xfce desktop. Other well-regarded desktop environments, such as Cinnamon and MATE, got surprisingly few votes. The once popular GNOME still hasn't recovered from the blowback from its disliked design change from GNOME 2 to GNOME 3.

Firefox may struggle as a web browser in the larger world, but on Linux it's still popular. Firefox took first place with 51.7 percent of the vote. Chrome came in a distant second place, with the rest of the vote being divided between a multitude of obscure browsers.

LibreOffice won a whopping 89.6% of the vote for "best office suite" -- and Vim beat Emacs.
