Why Linus Torvalds Prefers x86 Over ARM ( 150

Linus Torvalds answered a question about his favorite chip architecture at the Linaro Connect conference. An anonymous Slashdot reader quotes PCWorld: People are too fixated with the instruction set and the CPU core, Torvalds said. But ultimately "what matters is all the infrastructure around the instruction set, and x86 has all that infrastructure... at a lot of different levels. It's open in a way that no other architecture is... Being compatible just wasn't as big of a deal for the ARM ecosystem as it has been traditionally for the x86 ecosystem... I've been personally pretty disappointed with ARM as a hardware platform, not as an instruction set, though I've had my issues there, too. As a hardware platform, it is still not very pleasant to deal with."
You can watch the whole half-hour conversation on YouTube. My favorite part is where Linus candidly acknowledges that "sometimes my grumpiness makes more news than my being nice... 99% of the time I'm a very happy manager, and I mentally pat people on the head all the time. That maybe then highlights the times when things don't work so well a bit more."

Linux Foundation Shares LinuxCon Highlights ( 50

An anonymous Slashdot reader writes: The Linux Foundation held its "LinuxCon Europe" this week, "where developers, sys admins, architects and all types and levels of technical talent gather together under one roof for education, collaboration and problem-solving to further the Linux platform." They've now updated their web site with photos and slide presentations.

The 44 presentations included a talk about Linux kernel security subsystem by kernel developer James Morris and an interesting talk by GitHub's Carol Smith arguing that mandatory math requirements can create a "steep barrier to entry" for people trying to launch programming careers. Karsten Gerloff also described how Siemens is making "strategic" use of free software.

Unity 8 Desktop Session Arrives in Ubuntu 16.10 ( 56

The latest updates to Ubuntu 16.10 Yakkety Yak add a Unity8 desktop session to the Ubuntu login screen. OMGUbuntu adds: Added to the Ubuntu meta package, the new Unity 8 desktop session will be available to try on all new installs and upgrades of Ubuntu 16.10, but only as an alternate login session to Unity 7. Unity 8 is not -- repeat: not -- going to be the default session in this release. Shipping it as a preview session is a great idea. It means to try Unity 8 on Ubuntu 16.10 you won't need to install a set of packages, or faff around with special set-up, or add a PPA. When at the Unity Greeter (aka the login screen) just click the session selector button, followed by 'Unity 8,' and then proceed to login as normal.

Linus Torvalds Says 'Buggy Crap' Made It Into Linux 4.8 ( 294

Two days after Linus Torvalds announced the release of Linux 4.8, he began apologizing for a bug fix gone bad. The Register reports: "I'm really sorry I applied that last series from Andrew just before doing the 4.8 release, because they cause problems, and now it is in 4.8 (and that buggy crap is marked for stable too)." The "crap" in question is an attempt to fix a bug that's been present in Linux since version 3.15. Torvalds rates the fix for that bug "clearly worse than the bug it tried to fix, since that original bug has never killed my machine!" Torvalds isn't happy with kernel contributor Andrew Morton, who he says is debugging with a known bad use of BUG_ON(). "I've ranted against people using BUG_ON() for debugging in the past. Why the f*ck does this still happen?" Torvalds writes, pointing to a 2002 post to the kernel mailing list outlining how to do BUG_ON() right. He later adds "so excuse me for being upset that people still do this shit almost 15 years later."

New Project Lets You Install Arch Linux In the Windows Subsystem For Linux 77

prisoninmate writes: Softpedia reports that there's a new project on GitHub, called alwsl, which promises to let you install the Arch Linux operating system on Windows 10's new WSL (Windows Subsystem for Linux) feature, which allows users to run native Linux command-line tools directly on the Windows operating system alongside their modern desktop and apps. For example, Canonical and Microsoft brought Bash on Ubuntu on Windows using the new WSL functionality. For now, the alwsl project, which is developed by a group of German developers that call themselves "Turbo Developers," offers a .bat file that you can use to install Arch Linux on a WSL (Windows Subsystem for Linux) host, but the software is in developer preview stage. The first stable release, alwsl 1.0 will be able not only to install Arch Linux on the Windows Subsystem for Linux host in Windows 10 editions that support it, but also to create and manage users and snapshots. Also, it looks like it will get rolling upgrades just like a normal Arch Linux installation gets. The final release is expected to launch on December 2016, and you can monitor its development progress on GitHub.

KDE Plasma 5.8 LTS Desktop Officially Released ( 72

prisoninmate writes from a report via Softpedia: KDE will celebrate 20 years of activity on October 14, 2016, and they've just released the first LTS (Long Term Support) version of the KDE Plasma desktop environment. Prominent new features of KDE Plasma 5.8 LTS include support for desktop widgets, a new system-wide search functionality that promises to let users easily search their KDE desktops for everything they want, including apps, music, videos, files, folders, etc., a new tool to get hot new stuff for your KDE Plasma desktop, such as wallpapers, widgets, desktop effects, or window styles, and infinite customization possibilities. Moreover, KDE Plasma 5.8 LTS comes with a unified look for the default Breeze theme so that, no matter what type of application you're using (Qt4, GTK2, GTK3, or Qt5), it will look the same, mobile phone notifications, along with the ability to use your smartphone as a PC remote, transfer files or mute music during calls, all with the new KDE Connect plasmoid. There's also Right-to-Left (RTL) language support, simplified global shortcuts, improvements to many applets, and much better Wayland support. KDE Plasma 5.8 LTS will receive nine point releases until 2018. "Today KDE releases its first Long Term Support edition of its flagship desktop software, Plasma," reads the announcement. "This marks the point where the developers and designers are happy to recommend Plasma for the widest possible audience be they enterprise or non-techy home users. If you tried a KDE desktop previously and have moved away, now is the time to re-assess, Plasma is simple by default, powerful when needed."

Ubuntu 16.04 Available in Latest Insider Update To Windows 10 ( 127

The latest Windows 10 Insider preview -- build 14936 -- features Ubuntu 16.04 LTS. When a user enables the 'Bash on Ubuntu on Windows' feature for the first time, OMGUbuntu reports, Windows 10 now installs an Ubuntu 16.04 (Xenial Xerus) image instead of Ubuntu 14.04 (Trusty Tahr). From the report: The updated version of Ubuntu in the WSL only affects new instances, i.e., those created by running lxrun.exe /install or on the very first run of the bash.exe setup. It is possible to upgrade WSL instances from Ubuntu 14.04 to Ubuntu 16.04 manually by running the do-release-upgrade command. Other changes in the WSL in Build 14936 include support for chroot system call, epoll support for /dev/null and the ability for bash -c to redirect to a file.

Linus Torvalds Officially Announces the Release of Linux Kernel 4.8 ( 95

Slashdot reader prisoninmate brings news from Softpedia: Today, Linus Torvalds proudly announced the release and availability for download of the Linux 4.8 kernel branch, which is now the latest stable and most advanced one. Linux kernel 4.8 has been in development for the past two months, during which it received no less than eight Release Candidate testing versions that early adopters were able to compile and install on their GNU/Linux operating system to test various hardware components or simply report bugs...

A lot of things have been fixed since last week's RC8 milestone, among which we can mention lots of updated drivers, in particular for GPU, networking, and Non-Volatile Dual In-line Memory Module (NVDIMM), a bunch of improvements to the ARM, MIPS, SPARC, and x86 hardware architectures, updates to the networking stack, as well as to a few filesystem, and some minor changes to cgroup and vm.

The kernel now supports the Raspberry Pi 3 SoC as well as the Microsoft Surface 3 touchscreen.

Multiple Linux Distributions Affected By Crippling Bug In Systemd ( 508

An anonymous reader writes: System administrator Andrew Ayer has discovered a potentially critical bug in systemd which can bring a vulnerable Linux server to its knees with one command. "After running this command, PID 1 is hung in the pause system call. You can no longer start and stop daemons. inetd-style services no longer accept connections. You cannot cleanly reboot the system." According to the bug report, Debian, Ubuntu, and CentOS are among the distros susceptible to various levels of resource exhaustion. The bug, which has existed for more than two years, does not require root access to exploit.

Linux Mint Unveils New 'Mintbox Mini Pro' Desktop ( 70

It's been 18 months since the original Mintbox Mini launched, and this week saw the release of the new Mintbox Mini Pro (which costs just $100 more). BrianFagioli quotes BetaNews: That extra money gets you a faster processor, more powerful graphics, double the storage, twice the RAM, improved Wi-Fi, Bluetooth, and an additional Ethernet port... This diminutive desktop is the same size as the previously-released Mintbox... Thankfully, it retains the same cute appearance and Linux Mint branding.
Their article calls it a "beautiful little computer that comes pre-loaded with Linux Mint 18 Cinnamon (64-bit)," and the Linux Mint blog promises this fanless device offers "better passive cooling thanks to an all-metal black housing" -- and comes with six different USB ports.

Raspberry Pi Foundation Unveils New LXDE-Based Desktop For Raspbian Called PIXEL ( 47

Raspberry Pi Foundation's Simon Long has unveiled a new desktop environment for the Debian-based Raspbian GNU/Linux operating system for Raspberry Pi devices. From a Softpedia report (submitted by an anonymous reader):Until today, Raspbian shipped with the well-known and lightweight LXDE desktop environment, which looks pretty much the same as on any other Linux-based distribution out there that is built around LXDE (Lightweight X11 Desktop Environment). But Simon Long, a UX engineer working for Raspberry Pi Foundation, was hired to make it better, transform it into something that's more appealing to users. So after two years of work, he managed to create a whole new desktop environment for Raspbian, the flagship operating system for Raspberry Pi single-board computers developed and distributed by Raspberry Pi Foundation. Called PIXEL, the new Raspbian desktop offers a more eye-candy design with the panel on top (not on the bottom like on a default LXDE setup), new icons, new Applications Menu, and new theme. "It's actually surprisingly easy to hack about with the LXDE desktop once you get your head around what all the bits do, and since then I've been slowly chipping away at the bits that I felt would most benefit from tweaking," reveals Simon Long. "Stuff has slowly been becoming more and more like my original concept for the desktop; with the latest changes, I think the desktop has reached the point where it's a complete product in its own right and should have its own name."

Long-time Slashdot reader DeQueue writes: Back in 2011 Fabrice Bellard, the initiator of the QEMU emulator, wrote a PC emulator in JavaScript that let you boot Linux in your browser. But he didn't stop there.

On his website he now has images that let you boot Oberon, Arch Linux, FreeDOS, OpenBSD, Solar OS and more recent versions of Linux such as 2.6 or 3.18 (the 3.18 image includes internet access). You can also boot to a CD image, or a floppy image, or a hard drive disk image on your local machine. And, if you don't need yet another operating system on your computer, you can even boot to Bootchess and play chess


SolidRun x86 Braswell MicroSoM Runs Linux and Full Windows 10, Destroys Raspberry Pi ( 205

BetaNews has a report today about a company called SolidRun, which has announced an Intel Braswell-based MicroSoM. Unlike the ARM-powered Raspberry Pi, this is x86 compatible, meaning it can run full Windows 10. Plus, if you install a Linux distro, there will be far more packages available, such as Google Chrome, which is not available for Pi. Heck, it can probably serve as a secondary desktop, Brian with the site writes. From the report: At 53mm by 40mm, these new MicroSoMs provide unheard of design flexibility while also eliminating the headache of having to design complicated power-delivery subsystems thanks to its single power input rail design. SolidRun's Braswell MicroSoM also offers flexibility in RAM options, ranging from 1GB to 8GB configurations, and offers on-board support of eMMC storage up to 128GB. Its robust design and unsurpassed HD Edge surveillance, event detection, and statistical data-extraction capabilities makes it the platform of choice for mission-critical applications requiring guaranteed reliability," says Solidrun.It starts at $117, the website has more details on specifications.

Lenovo Denies Claims It Plotted With Microsoft To Block Linux Installs ( 181

Reader kruug writes: Several users noted certain new Lenovo machines' SSDs are locked in a RAID mode, with AHCI removed from the BIOS. Windows is able to see the SSD while in RAID mode due to a proprietary driver, but the SSD is hidden from Linux installations -- for which such a driver is unavailable. Speaking to The Register today, a Lenovo spokesperson claimed the Chinese giant "does not intentionally block customers using other operating systems on its devices and is fully committed to providing Linux certifications and installation guidance on a wide range of products."
Complaints on Lenovo's forums suggest that users have been unable to install GNU/Linux operating systems on models from the Yoga 900S to the Ideapad 710S, with one 19-page thread going into detail about the BIOS issue and users' attempts to work around it.
