Linux.com: Minijail: Google’s Tool To Safely Run Untrusted Programs

Thursday 29th of September 2016 02:30:54 PM

Google’s Minijail sandboxing tool could be used by developers and sysadmins to run untrusted programs safely for debugging and security checks, according to Google Software Engineer Jorge Lucangeli Obes, who spoke last month at the Linux Security Summit. Obes is the platform security lead for Brillo, Google's Android-based operating system for Internet-connected devices.

TuxMachines: Qubes OS 3.2 has been released!

Thursday 29th of September 2016 02:29:02 PM

I’m happy to announce that today we’re releasing Qubes OS 3.2!

This is an incremental improvement over the 3.1 version that we released earlier this year. A lot of work went into making this release more polished, more stable and easier to use than our previous releases.

One major feature that we’ve improved upon in this release is our integrated management infrastructure, which was introduced in Qubes 3.1. Whereas before it was only possible to manage whole VMs, it is now possible to manage the insides of VMs as well.

TuxMachines: Red Hat claims headway in Asia, bets big on container and hybrid cloud

Thursday 29th of September 2016 02:26:53 PM

While the smallest in terms of revenue contribution, Asia is Red Hat's fastest growing region and is likely to continue its upwards trajectory as emerging markets roll out new infrastructure.

Developing nations in the region were embarking on many net new infrastructure projects, rather than replacement for existing technology, and open source would be involved in a large share of such projects. The decisions on which technology to deploy would rarely be between proprietary or open source, but rather on which open source vendor to go with or to do so internally, said Red Hat President and CEO Jim Whitehurst.

Reddit: So what's going on with the Lenovo Yogas?

Thursday 29th of September 2016 12:29:26 PM

I've recently started getting more interested in Linux and I'm going to upgrade from my 2011 Macbook Pro to a Windows machine when the Kaby Lake laptops start showing up to dual boot Windows and Linux on.

I want to get a 2 in 1 machine and the Lenovo Yoga 710 is the machine I'm the most interested in, but I've seen a lot of posts here and on tech websites that Lenovo prevents you from installing other OS's on the Yoga due to something with the hard drive configuration? Is that true or is it just disinformation being spread around?

I've read that it has something to do with Microsoft Signature Edition machines, is the problem only affecting those machines?

TuxMachines: Sony Xperia X Compact review: Small Android is still good, but not much better

Thursday 29th of September 2016 12:19:35 PM

Sony's Xperia X Compact is basically the newest version of the Z5 Compact that hit the US earlier this year. But just because it's a newer version of the (comparatively) tiny handset doesn't mean it's an upgrade in every way. Sony is pushing the camera sensors in the X Compact and the flagship-level XZ, as well as new features like five-axis image stabilization and HDR photo mode. Sony knows cameras, so we know the shooter in the X Compact will at least be competent. However, it has to be good enough to encourage photography buffs to shell out $499 for this unlocked handset while delivering solid performance across the board as well.

TuxMachines: The Tiny Internet Project, Part I

Thursday 29th of September 2016 12:11:33 PM

As LJ readers well know, Linux drives many of the technologies we use every day, from smart TVs to Web servers. Linux is everywhere—except most homes and classrooms.

That's a problem if we want to help breed the next generation of engineers and computer scientists. In fact, if teenagers (or any other group of curious individuals) want to learn about Linux, they often must rely on a geeky friend or parent willing to show them the way.

This three-part series seeks to change that by offering a way for anyone to learn about Linux by building what is essentially a tiny, self-contained Internet. Using old equipment and free software, you'll build a private network (with your own domain name), build Web sites, set up an e-mail server, install and use a database, and set up a Linux distro mirror.

Phoronix: Ubuntu 16.10 Doesn't Change Much With Performance, Clear Linux Still Leads In Most Tests

Thursday 29th of September 2016 11:58:25 AM
Given yesterday's Ubuntu 16.10 final beta release ahead of the official "Yakkety Yak" debut in two weeks, I decided to run some benchmarks of Ubuntu 16.10 compared to Ubuntu 16.04.1 LTS on the same system plus also throwing in the Intel Clear Linux distribution given it tends to be one of the most performant...

Reddit: Linux on 2x 4K sluggish performance?

Thursday 29th of September 2016 10:20:35 AM

Hey everybody,

I recently upgraded by 2x 1080p screen setup to a 4K display. Running Ubuntu with Unity ended up being very pleasant with good UI scaling. Unfortunately I kinda missed a second monitor so I decided to get a second 4K display (same model).

I arrived yesterday and I've noticed some concerning performance drops and I don't know where to attribute them.

Basically, when both 4K displays are enabled (one over DP, one over HDMI), I get significant lag on the HDMI display (only 30hz refresh rate) but the DP display also starts lagging, generally everything becomes more sluggish and unpleasant to use (I can record a video if you're interested).

The way I say it there are 4 things on my mind right now:

  1. Does anyone else have this setup and can confirm any problems? (Aka is it a Linux problem?)
  2. Is my CPU the bottleneck?
  3. Is my GPU the bottleneck?
  4. Is the HDMI connection causing issues?

My hardware:

  • Phenom II X6, 1090T @ 3.8GHz (quite old and slow)
  • Sapphire R9 380X, 4GB
  • 16GB DDR3 1600MHz
  • Running Kernel 4.8-rc7, Mesa 12.1, amdgpu

I'm wondering if some of you guys have similar setups as me (aka 2x 4K side by side) and if you're having problems. And if not, what hardware are you using?

I'm trying to narrow down the sources of potential problems to decide if I should send back the monitor or if it's worth upgrading a different component in my system to make it work. Thanks.

TuxMachines: Don’t be a stranger to GIMP, be GIMP…

Thursday 29th of September 2016 10:03:51 AM

I can try and do more coding, more code reviewing, revive designing discussions… that’s cool, yet never enough. GIMP needs more people, developers, designers, community people, writers for the website or the documentation, tutorial makers… everyone is welcome in my grand scheme!

Many of my actions lately have been towards gathering more people, so when I heard about the GNOME newcomers initiative during GUADEC, I thought that could be a good fit. Thus a few days ago, I had GIMP added in the list of newcomer-friendly GNOME projects, with me as the newcomers mentor. I’ll catch this occasion to remind you all the ways you can contribute to GIMP, and not necessarily as a developer.

TuxMachines: Alphabet's Plans to Create Android PCs Should Make Microsoft a Little Nervous

Thursday 29th of September 2016 09:38:53 AM

Four years after Microsoft (MSFT) first tried to give the world unified PC/mobile operating systems via the dual fiascoes known as Windows 8 and Windows RT, Alphabet's (GOOGL) Google appears set to take its own stab at the concept. And there are reasons to think the company will see a measure of success.

Citing "two independent and reliable sources," Android Police reports Google plans to launch a notebook in the third quarter of 2017 that will likely be the first new device to showcase Andromeda, a version of Android that will integrate many features associated with Google's Chrome OS PC operating system.

The notebook will reportedly be called the Pixel 3, and carry a $788 price. Its feature set reportedly include a 12.3-inch display, an Intel (INTC) processor, a glass trackpad, a tablet mode and stylus support.

Security News

  • Report: Linux security must be upgraded to protect future tech
    The summit was used to expose a number of flaws in Linux's design that make it increasingly unsuitable to power modern devices. Linux is the operating system that runs most of the modern world. It is behind everything from web servers and supercomputers to mobile phones. Increasingly, it's also being used to run connected Internet of Things (IoT) devices, including products like cars and intelligent robots.
  • security things in Linux v4.6
    Hector Marco-Gisbert removed a long-standing limitation to mmap ASLR on 32-bit x86, where setting an unlimited stack (e.g. “ulimit -s unlimited“) would turn off mmap ASLR (which provided a way to bypass ASLR when executing setuid processes). Given that ASLR entropy can now be controlled directly (see the v4.5 post), and that the cases where this created an actual problem are very rare, means that if a system sees collisions between unlimited stack and mmap ASLR, they can just adjust the 32-bit ASLR entropy instead.

  • Linux Unable To Boot Lenovo Yoga 900 & 900; Is Microsoft At Fault?
    The popular device developer Lenovo has verified the claims that Lenovo Yoga 900 and 900s unable to boot Linux OS but only Microsoft Windows 10. The new Lenovo convertible laptop, Lenovo Yoga 900 and 900s, would reject and decline any attempt to install Linux operating system, making users turn their heads to Microsoft as the suspect for this issue. [...] This issue about the OS started when an identity of BaronHK posted on Reddit about installing Linux on the latest Lenovo Yoga book in which BaronHK encountered being blocked by a locked solid state drive (SSD) which Linux cannot define itself, and come up to link the issue to Microsoft.

    The final Ubuntu 16.10 Beta for "Yakkety Yak" was released this week and we found its performance doesn't differ much from Ubuntu 16.04 LTS (with the exception of the newer graphics stack) while here are some results comparing it to other modern Linux distributions. Tested for this quick, one-page-article comparison were Ubuntu 16.04.1 LTS, Ubuntu 16.10 Beta 2, Clear Linux 10660, Fedora 24, openSUSE Tumbleweed 20160927, and the Arch-based Antergos 16.9-Rolling release.

    Of course, I know for a fact that many people use local recipes to cross-compile WebKit2GTK+ for ARM (or simply build in the target machine, which usually takes a looong time), but those are usually ad-hoc things and hard to reproduce environments locally (or at least hard for me) and, even worse, often bound to downstream projects, so I thought it would be nice to try to have something tested with upstream WebKit2GTK+ and publish it on trac.webkit.org,
