Oracle Powers New Exadata SL6 with SPARC Linux
Oracle is doubling down on its SPARC silicon architecture, announcing a new SPARC-powered Exadata system on Feb 6. The Exadata SL6 is Oracle's first Exadata system that is not powered by Intel x86.
The new Exadata SL6 is similar in configuration to the x86-based Exadata X6-2 in that both systems are highly optimized for database workloads and both use Oracle Linux. The SL6 uses Oracle SPARC T7-2 chips, which are based on the SPARC M7 processor.

Linux Kernel 3.18 Reaches End of Life, Users Urged to Move to Linux 4.9 or 4.4
Today, February 8, 2017, renowned Linux kernel maintainer Greg Kroah-Hartman put an end to the release cycle of the long-term supported (LTS) Linux 3.18 kernel series by releasing what appears to be the last hotfix.
Linux kernel 3.18.48 LTS is here and is the last in the series, which was marked for a January 2017 extinction since mid-April last year. According to the appended shortlog, the new patch changes a total of 50 files, with 159 insertions and 351 deletions.
Inside Real-Time Linux
Real-time Linux (RTL), a form of mainline Linux enabled with PREEMPT_RT, has come a long way in the past decade. Some 80 percent of the deterministic PREEMPT_RT patch is now available in the mainline kernel itself. Yet, backers of the strongest alternative to the single-kernel RTL on Linux -- the dual-kernel Xenomai -- continue to claim a vast superiority in reduced latency. In an Embedded Linux Conference Europe presentation in October, Jan Altenberg rebutted these claims while offering an overview of the real-time topic.

A fundamental component of the text editor called the display layer has been redesigned to rely on a new data structure that is implemented in C++. These changes enable Atom to open larger files more quickly while using much less memory. Improvements in this area are ongoing, so expect more in upcoming releases.
Atom 1.14 Hackable Text Editor Launches with Improved Large File Performance
GitHub's Ian Olsen is announcing today, February 8, 2017, the general availability of the Atom 1.14 open-source and multiplatform hackable text editor for all supported platforms, including GNU/Linux, macOS, and Microsoft Windows.
Launched exactly one month after the release of Atom 1.13, the new Atom 1.14 release does not appear to be a major milestone, as it only adds 64-bit installation support for Microsoft Windows operating systems, improved MRU tab traversal with a bunch of fixes, as well as large file performance across all platforms.
Why I Swapped VLC for MPV
In fact, if I were to you all what video player you use on Ubuntu I’d be cowered by the collective cry of ‘VLC’!
And quite right too. VLC is open-source, obscenely powerful and plays dang well near everything you chuck at it,
This release fixes a security bug - admins could delete protected aliases like abuse@ (CVE-2017-5930). Besides that, some non-security bugs were fixed. Read the official announcement for details.
Time for another update of RcppArmadillo with a new release 0.7.700.0.0 based on a fresh Armadillo 7.700.0. Following my full reverse-dependency check of 318 package (commit of log here), CRAN took another day to check again.

Solarized colour theme
A while back I was looking for some information on the web, and happened upon a blog post about the subject. I don't remember what I was looking for, but on the same blog, there was a screen shot of what I then learned was the Solarized theme. This caught my eye that I decided to try it myself ASAP.
Up until last year, I've been using for many years the 'black on light yellow' xterm scheme. This is good during the day, but too strong during night, so on some machines I switched to 'white on black', but this was not entirely satisfying.
The solarized theme promises to have consistent colours over both light and dark background, which would help to make my setups finally consistent, and extends to a number of programs. Amongst these, there are themes for mutt on both light and dark backgrounds using only 16 colours. This was good, as my current hand-built theme is based on 256 colours, and this doesn't work well in the Linux console.

Red Hat IT Single Sign On(SSO) Runs on Red Hat Virtualization
Red Hat is best known for Red Hat Enterprise Linux (RHEL) and for being a leader in driving open source development projects. In many cases, the upstream projects then become Red Hat products that provide enterprise functionality elsewhere in the stack.
Red Hat Enterprise Linux Across Architectures: Everything Works Out of the Box
Since the Red Hat Enterprise Linux Server for ARM Development Preview 7.3 became available I’ve been wanting to try it out to see how the existing code for x86_64 systems works on the 64-bit ARM architecture (a.k.a. aarch64).
Going in, I was a bit apprehensive that some kind of heavy lifting would be needed to get things working on the ARM platform. My experience with cross-architecture ports with other distros (before I joined Red Hat) indicated going through dependency hell as I frantically tried to find equivalent packages for the ARM architecture. Needless to say, most of these porting exercises ended with massive amounts of productivity loss and potential security exposures as I downloaded packages from unknown sources, all the time hoping one of them would work.

The next big things, 2017 edition.
Along with several people on the Fedora Engineering team, I recently attended the DevConf.cz 2017 event. The conference has grown into an amazingly successful gathering of open source developers. Most attendees live in Europe but there were some from every continent. The coverage spanned all the big open source buzz-generating technologies. Session topics included containers, PaaS, orchestration and automation, and DevOps.

Reducing the bandwidth requirements for keeping Fedora up to date
Keeping your Fedora installation up to date can become a problem if your ISP imposes a strict datacap or if you’re stuck with only an expensive mobile data connection. Here are a few tricks for lowering Fedora’s system update bandwidth requirement.
Is this the perfect Android phone?
The graphic designers behind YouTube channel DBS Designing are back, and this time they’ve set their sights on the Chinese Android smartphone startup OnePlus. The company’s OnePlus 3T is without question one of the hottest smartphones money can buy right now. Featuring a sleek all-metal design, plenty of power and my personal favorite custom Android build on the market, the OnePlus 3T is just about as good as it gets right now for Android.
MrMobile's best Android tablet (is from 2015)
It's been 15 months since Google's Pixel C launched, and it hasn't diminished in quality (or price). It still has some annoying bugs, and there's still software that just won't work in landscape mode, but after over a year since release, I still find myself gravitating toward it whenever I'm able to leave my bigger machines behind.

Android Wear 2.0 is an evolutionary update to Google’s smartwatch OS
Google is officially launching Android Wear 2.0 today — the biggest update to the company’s wearable operating system since its launch in 2014.
If you’re not a Wear aficionado who has been patiently waiting for this release, you probably remember Wear 2.0 from its Google I/O announcement last May. Even though in day-to-day use, the updated version feels very much like the next logical evolution of Wear, it took Google far longer than expected to launch it.

Another Potential CPU Optimization For Mesa: Quadratic Probing
Mesa developer Thomas Helland is looking at reviving an old set of Mesa patches that could help out in some CPU-bound scenarios.
Helland re-discovered some old Mesa patches from April 2015 for implementing quadratic probing in hash tables for being faster rather than the linear re-probing hash table as is used currently. Helland explained further in the patch, "This will allow us to remove the large static table and use a power of two hash table size that we can compute on the fly. We can use bitmasking instead of modulo to fit our hash in the table, and it's less code. By using the algorithm hash = sh + i/2 + i*i/2 we are guaranteed that all retries from the quad probing are distinct, and so we should be able to completely fill the table."
Libinput X.Org Driver Updated With New Capabilities
Libinput is the input handling library that originated with Wayland but has since been adopted by Mir as well as X.Org when using the xf86-input-libinput handling driver. This xf86-input-libinput adaptation for X.Org Servers has seen a new release today.
Last month marked the libinput 1.6 release with new features to the input library. Now xf86-input-libinput has been upgraded for improving the support for this generic input handling implementation on xorg-server systems.

Wayland's Weston 2.0 Beta Released
One day after the Wayland 1.13 Beta, the reference Weston compositor is updated to its 2.0 beta state.
Wayland's reference compositor, Weston, is moving to version 2.0 rather than version 1.13 since its new output configuration ABI has broken Weston's ABI. In addition to the new output handling API, Weston 2.0 has seen work on DRM compositor improvements, support for using EGL_KHR_swap_buffers_with_damage, initial window positioning for XWayland apps, desktop shell refinements, and other improvements.
Ahead of Mobile World Congress (MWC17) happening later this month, Jolla has released Sailfish OS 2.1.
