Linux never sleeps. Linus Torvalds is already hard at work pulling together changes for the next version of the kernel (4.11). But with Linux 4.10 now out, three groups of changes are worth paying close attention to because they improve performance and enable feature sets that weren’t possible before on Linux.
Here’s a rundown of those changes to 4.10 and what they likely will mean for you, your cloud providers, and your Linux applications.
VIA unveiled an SODIMM-style COM based on its Cortex-A9 WM8850 SoC, with 512MB RAM and 8GB eMMC, plus Ethernet, CSI, graphics, USB, and serial ports.
The 68.6 x 43mm “SOM-6X50” computer-on-module appears to be VIA’s second-ever ARM COM. Back in Sept. 2015, the company released a 70 x 70mm Qseven form factor QSM-8Q60 COM, based on a 1GHz NXP DualLite SoC.
Alpine Linux, a security-focused lightweight distribution of the platform, may get its own Java port. Alpine is popular with the Docker container developers, so a Java port could pave the way to making Java containers very small.
A proposal floated this week on an OpenJDK mailing list calls for porting the JDK (Java Development Kit), including the Java Runtime Environment, Java compiler and APIs, to both the distribution and the musl C standard library, which is supported by Alpine Linux. The key focus here is musl; Java has previously been ported to the standard glibc library, which you can install in Alpine, but the standard Alpine release switched two years ago to musl because it’s much faster and more compact
Linux Foundation backed Xen Project helps to advance the state of the MirageOS unikernel operating system with a new release that now supports the KVM hypervisor.
The open-source MirageOS unikernel project reached a major milestone on Feb. 23, with the launch of MirageOS 3.0. The basic idea behind a unikernel is that it is a highly-optimized and purpose-built operating system that can help to enable efficient operation and delivery of applications.
The MirageOS 1.0 release debuted back in December 2013 as an effort led by the Linux Foundation's Xen hypervisor virtualization project. With the new MirageOS 3.0 release, the unikernel is now expanding beyond the confines of the Xen hypervisor and now also supports the KVM and Bhyve hypervisors as well.
Today the Linux Foundation consolidated the ECOMP and OPEN-O project to form the new Open Network Automation Project (ONAP). ECOMP perhaps has had the shortest life-span of any Linux Foundation project, lasting barely a month. ECOMP only becamean official Linux Foundation project a few short weeks ago, after being donated by AT&T. The Enhanced Control, Orchestration, Management and Policy (ECOMP) is an effort that AT&T has been building for several years to help enable its network transformation for virtualization.
OPEN-O on the other hand was announced a year ago, as the Open Orchestrator effort.
After I resolved to adopt Linux, my confidence grew slowly but surely. Security-oriented considerations were compelling enough to convince me to switch, but I soon discovered many more advantages to the Linux desktop.
For those still unsure about making the transition, or those who have done so but may not know everything their system can do, I'll showcase here some of the Linux desktop's advantages.
You may have noticed that there’s no stock symbol next to Linux’s name. This important OS isn’t made by a public company… or even a company at all.
Linux software is open source. In other words, it’s not a commercial product which anyone owns. Rather, it’s free software which is developed and improved pro bono by the programmers who use it.
As a result of this democratized development process, Linux is more customizable than a commercial OS. Windows and MacOS both have proprietary designs with usage restrictions, but not so with Linux.
This makes Linux software ideal for the advanced programmers and IT professionals who make cloud computing possible. They often like to tinker with hardware and software in order to optimize it for their purposes.
Kopano announced big news yesterday about being included in openSUSE’s factory codebase as development proceeds to be in openSUSE’s upcoming release, which was a big first step toward inclusion into openSUSE downstream.
“We are straight on the path to be included with openSUSE Leap 42.3 already, which has started development just last December,” wrote Michael Kromer in a news release yesterday. “You can find the downstream requests from Factory to Leap 42.3 here: Core and WebApp.”
Being one of the most popular Linux distros, Kopano expressed delight to be the first distribution to pick the communication solution.
The main change is the comeback of Firefox, built with GTK3 and multithreading enabled by default : This build of Firefox starts and react nearly as fast as Chromium, and with many tabs opened : scales much better in terms of responsiveness and memory footprint. You will also notice some improvements around ffmpeg, and MPV which is from now the main media player in Zenwalk. Gstreamer has been dropped from ISO but is still available from Slackware repositories. Of course this ISO contains many updated packages (see changelog below).
Today, Technologic Systems, Inc. announced that it will be partnering with Canonical to make Ubuntu Core available for their TS-4900 Compute Module. The TS-4900 is a high-performance Computer on Module (CoM) based on the NXP i.MX6 CPU which implements the ARM® CortexTM A9 architecture clocked at 1 GHz.
Takashi Iwai has submitted the sound subsystem updates for the Linux 4.11 kernel with most of that work happening in the audio driver space.
Jerome Glisse and others have been working on the rather cool Heterogeneous Memory Management support for the Linux kernel going back several years. While Jerome hoped to see HMM merged for Linux 4.11, it will be sitting out at least one more cycle.
