The First Vivid-Based Ubuntu Touch Image Has Been Released

Filed under
Ubuntu

As I have previously announced, the Ubuntu Touch development branch is based on Ubuntu 15.04 Vivid Vervet, while the Ubuntu RTM branch is still using Ubuntu 14.10 Utopic Unicorn as code base, because it has already received stability improvements and will by default on the first Ubuntu powered Meizu phone. Currently, all the new features are implemented on the Ubuntu-Devel branch, the RTM one receiving only fixes.

Security-Minded Qubes OS Will Satisfy Your Yen for Xen

Security

It has advanced far beyond the primitive proof of concept demonstrated more than four years ago. Release 2 (beta), which arrived in late September, is a powerful desktop OS.

Qubes succeeds in seamless integrating security by isolation into the user experience. However, comparing Qubes to a typical Linux distro is akin to comparing the Linux OS to Unix.

Sad News! ;-)

Microsoft

So, XP is dead, “7” is dying, “8” is a zombie, and “10” is vapourware with nowhere to call home. M$ continues layoffs. POOF! It all falls down. In the meantime Google and the OEMs will crank out many millions of ChromeBooks. Canonical, Linpus, RedHat, Suse… and the OEMs will crank out many millions of GNU/Linux PCs. Several OEMs will crank out many millions of GNU/Linux thin clients. Android/Linux will reverberate with another billion or so units of small cheap computers(tablets, smartphones). This looks like good news to me.

Android creator Andy Rubin is leaving Google

Google

The move is, perhaps, not a total surprise. Last March, Rubin left the Android group and was replaced by Sundar Pichai. His latest project, as detailed in a lengthy New York Times report in December, was creating robots for a project outside of the company's Google X lab, something that dovetailed with Google's shopping spree of robotics companies. In 2012, there were also rumors abound that Rubin planned to leave for a stealth-mode startup called CloudCar, though they were vehemently denied.

NVIDIA's Linux Driver On Ubuntu 14.10 Can Deliver Better OpenGL Performance Than Windows 8.1

Filed under
Graphics/Benchmarks

The same Intel Core i7 4770K system used for yesterday's Windows vs. Linux graphics benchmarks were used when benchmarking the GeForce GTX 780 Ti, 970, and 980 graphics cards. Windows 8.1 Pro x64 had all available system updates at the time and was running the NVIDIA 344.48 WHQL binary driver that was their latest release at the time of testing. When running Ubuntu 14.10 x86_64 on the system with its Linux 3.16 kernel, the NVIDIA 343.22 driver was used. The 343.22 driver was the latest publicly available proprietary Linux driver at the time of testing and their first to support the GTX 970/980 under Linux. All of the same hardware was used under each operating system and each OS was with its software default settings as were the driver settings.

As promised, the Tizen IVI team announced the release of the Tizen IVI 3.0-M3-Oct2014 Release for In-Vehicle Infotainment (IVI). The major changes are below:

Improved Modello UI experience
The OS is available in 32-bit and 64-bit backed by a Long Term Support Initiative Linux kernel.
The multi-user application framework has support for single/all-user app deployment scenarios.
Developing applications for Modello is easier than ever using the Tizen_IVI_SDK with support for vehicle webAPIs powered by Crosswalk.
For lower level development Automotive Message Broker (AMB) contains CAN plugin generator tools and a JavaScript engine for rapid plugin prototyping. System resources are now handled by Murphy. MinnowBoard MAX will run this latest instalment of Tizen IVI 3.0 M3 and offers customers an affordable entry-level SDP.

Linux 3.16.y.z extended stable support

Filed under
Linux

The Ubuntu kernel team is pleased to announce that we will be
providing extended stable support for the Linux 3.16 kernel until
April 2016 as a third party effort maintained on our infrastructure.
The team will pick up stable maintenance where Greg KH left off with
v3.16.7 [1]. Thank you, Greg.

In addition to the Ubuntu 14.10 "Utopic Unicorn" release, the Debian 8
"Jessie" release will also be based on this kernel [2]. Since the
regular support for "Jessie" will go beyond April 2016, after this
date Ben Hutchings (or myself) will continue the Linux 3.16 kernel
maintenance.

  • Ravgeet Dhillon: Offline Toast notification in Nuxt/Vue app

    We have often seen apps telling us that “You are offline. Check your network status.”. It is not only convenient to do so but adds to a great UX. In this blog, we will look at how can we display a toast notification in a Nuxt/Vue app whenever the user goes offline or online. This will also help us to understand how to use computed and watch properties together. [...] Hurray! Our toast notifications are working perfectly fine. So using the combined magic of computed and watch properties, we can create outstanding workflows and take our Nuxt/Vue app to next level. If you any doubts or appreciation for our team, let us know in the comments below. We would be happy to assist you.

  • Stephen Michael Kellat: Leveraging LaTeX In This Time

    From time to time I like to bring up fun adventures in LaTeX. In these stranges times in the United States it is important to look at somewhat practical applications beyond the normal reports and formal papers most people think of. With a Minimum Working Example we can mostly look at an idea. The Comprehensive TeX Archive Network has a package known as newspaper which is effectively subject to nominative determinism. You can make things with it that look like newspapers out of the 1940s-1960s in terms of layout. The page on CTAN shows nice examples of its use and provides a nice story as to why the package was created. The example source file on CTAN has a bug in it, though. We're going to make a new one based on it. I am also going to add but not yet utilize the markdown package to the example.

  • GCC 11 Is On The Final Stage Of Development With 60+ High Priority Regressions - Phoronix

    GCC 11 entered its final stage of development today as it works towards releasing around the end of Q1 / early Q2 if their past cadence holds up. Before GCC 11.1 can debut as the first stable version, there are some 60+ "P1" high priority regressions that need to be resolved or otherwise demoted to lesser priority regressions. GCC 11 release manager Richard Biener this morning announced GCC 11 is now in stage four development meaning only regression fixes and documentation fixes are allowed. As of this morning the code-base is at 62 P1 regressions, another 334 P2 regressions, 35 P3 regressions, and more than 200 regressions of the lower P4/P5 status.

  • About CVE-2020-27348

    Well this is a doozey. Made public a while back was a security vulnerability in many Snap Packages and the Snapcraft tool used to create them. Specifically, this is the vulnerability identified as CVE-2020-27348. It unfortunately affects many many snap packages… [...] The problem arises when the LD_LIBRARY_PATH includes an empty element in its list. When the Dynamic Linker sees an empty element it will look in the current working directory of the process. So if we construct our search paths with an accidental empty element the application inside our Snap Package could be caused to load a shared library from outside the Snap Package’s shipped files. This can lead to an arbitrary code execution. It has been common to put a definition of the LD_LIBRARY_PATH variable into a Snap Package’s snapcraft.yaml that references a predefined $LD_LIBRARY_PATH as if to extend it. Unfortunately, despite this being common, it was poorly understood that SnapD ensures that the $LD_LIBRARY_PATH is unset when starting a Snap Package’s applications. What that means is that where the author tried to extend the variable they have inadvertantly inserted the bad empty element. The empty element appears because $LD_LIBRARY_PATH is unset so the shell will expand it to an empty string.
