  • Bus1: a new Linux interprocess communication proposal

    It is early days yet for bus1. Though it has been under development for a least eight months (based on Git history) and is based on even older ideas, there has been little public discussion. The follow-up comments on the kernel-summit email thread primarily involved people indicating their interest rather than commenting on the design. From my limited perspective, though, it is looking positive. The quality of the code and documentation is excellent. The design takes the best of binder, which is a practical success as a core part of the Android platform, and improves on it. And the development team appears to be motivated towards healthy informed community discussion prior to any acceptance. The tea-leaves tell me there are good things in store for bus1.

  • [Older] Open vSwitch Moves to the Linux Foundation

    Open Source usage and participation has increased across the industry in the last few years, driving the spotlight towards the technology powering the future of open collaboration. Similarly, with the rise of software defined networking (SDN) and network function virtualization (NFV), networking is going through its own star studded moment. As an early pioneer in the SDN space, Open vSwitch has been at the forefront of both of these trends, and has helped pioneer not only the concepts we all understand as SDN, but in the open cloud platform as well. Open vSwitch enables developers to easily connect and move between separate cloud environments. We at IBM have contributed heavily to Open vSwitch as part of our dedication to building the cloud as an open, accessible foundation for innovation – not a destination in and of itself.

LinuxCon to Highlight How Linux Has Changed in Its 25 Years

Filed under
Linux

When Linus Torvalds first got started on Linux 25 years ago, it was all about the kernel. For Torvalds today, in conversation after conversation, he will almost always reiterate that the kernel is still his primary focus. The difference between Linux today and Linux 25 years ago is that Linux is about much more than just Torvalds, or even the Linux kernel. Linux today is about the wider world that Linux enables. It's a world where the collaborative development model that Linux pioneered has been extended into every realm of software development.

Ten years ago, when I first met Jim Zemlin, his message was about trying to prevent the fragmentation of Linux by having the Linux Standards Base. While fragmentation is still a concern, it's no longer at the top of the list for Linux. Today Linux and the wider ecosystem it helps enable is the basis of the modern world, from the internet of things to smart phones, servers and everything in between.

As Zemlin has said many times in his state of Linux address at LinuxCon events over the years, "Linux is awesome."

More reading comprehension issues in Linux

Linux

Do you know the one difference between incompetent people who use Windows versus those who use Linux? The latter feel entitled and opinionated enough to twitter about their superiority complex. You just don't hear the average folks running Windows complain, because they have better things to do, like watch Youtube. Since you can't do that in Linux, because things break all the time, you masochistically waste your energy fixing your system so it can do what any decent Windows 98 box could 9,000 years ago, and then defend your choice with the classic zeal of a Stockholm Syndrome casualty.

This is an unfair comment toward all the Linux people who do care, do work hard, and do try to make better products, but I am not really sure what's the best way, if any, to convey my message to people with reading ability challenges. This is not a call to improve Linux and make it better and blah blah. I've expressed myself enough times on that. You know what the magic formula is and how to make Linux desktop succeed. It is to listen to me, because I'm always right. So the one piece still left is to sit down and read. There. And please, don't link this article in your blogs or whatever. The first response will be: clickbait. Or: he has disabled comments on his site. Don't. No need. Just read. Carefully. That's all.

Systemd Rolls Out Its Own Mount Tool

Filed under
Linux

Systemd-mount is the newest tool added to systemd by Lennart Poettering.

The systemd-mount command is similar to the traditional mount command on Linux systems but with some differences.

Lennart describes in the documentation for systemd-mount, "instead of executing the mount operation directly and immediately, systemd-mount schedules it through the service manager job queue, so that it may pull in further dependencies (such as parent mounts, or a file system checker to execute a priori), and may make use of the auto-mounting logic."

Tips on adding Linux to Your Developer Skill Set

Filed under
GNU
Linux
OSS

The time when developers and administrators can get by with only Microsoft in their bag of tricks is over. With Linux's continuing dominance and growth in server space and with Redmond now embracing open source with actions as well as words, even those who develop exclusively for the Windows platform are almost certain to find times when they need to wrap their heads around an aspect of the Linux kernel or some open source application.

If you've been following tech news, you know that across the board there is an increasing need for people with Linux skills, which has pushed the salaries available for those with certifiable Linux talents to record highs. This opens an opportunity in traditional Windows shops where fully certified Linux people might not be necessary, but where certified Windows people with good Linux skills have extra value.

In other words, you can increase your value as an employee simply by honing your Linux and open source skills, without the need to necessarily shell out big bucks to Red Hat or the Linux Foundation for certification. There are plenty of educational opportunities available online, some free and others offered with a very low price tag.

  • Kontena Launches Container Platform, Banks Seed Funding
    Startup Kontena has launched a container and microservices platform that, it claims, is designed to be developer friendly, easy to install and able to run at any scale -- attributes that, Kontena says, differentiate it from the current crop of container platforms. The Menlo Park, Calif.-based company, founded in March 2015, has also raised $2 million seed funding from Helsinki-based Lifeline Ventures. It also has a clever name: Say it out loud -- cute, huh? According to the team at Kontena Inc. , the startup's container and microservices platform requires zero maintenance, is designed for automatic updates, and runs on any infrastructure, including on-premises, cloud and hybrid. Combined, those attributes make it an easy-to-use alternative to platforms such as Docker, Kubernetes, Heroku and Mesosphere, the company says.
  • Stabilizing the world of hot and fast containers
    Containers are moving targets in multiple ways. With multiple tools, frameworks, implementations, and use cases to accomplish any task, it can be a fast-moving chaotic container world, which is a natural consequence of being young and popular. The good news is that all of this creative incubation is hugely productive, and because it's all open source everyone gets to share the benefits of all of this fabulous creativity. The bad news is that it's a giant energized cat herd. How do we know what direction to take? Must we plan for the work we do today to be obsolete in a few months? And, what about portability? I'd like to provide a few insights into the future of containers, and the direction we can expect the state of the art technology to take.
  • How DIGIT Created High Availability on the Public Cloud to Keep Its Games Running
    Emmanuel & Ross: HA is achievable on the public cloud. In our case, we couple redundancy across Availability Zone (AZ) with monitoring and autonomous systems to ensure our games can keep running. Using only one AZ will not ensure HA, as that entire zone could fail for a short time. Each of our applications runs in multiple containers at the same time. They're are all being monitored to handle current load. When one container is down, another takes its place. The same applies for all parts of our infrastructure. All services are autoscaling and behind a service discovery system. On top of this, nodes in our cluster are deployed across multiple AZs, each of which being an isolated network with its own NAT gateway. This way we can survive a whole zone going down.

  • LinuxCon: How Facebook Monitors Hundreds of Thousands of Servers with Netconsole
    The original kernel documentation for the feature explains that the netconsole module logs kernel printk messages over UDP, allowing debugging of problems where disk logging fails and serial consoles are impractical. Many organizations will choose to use syslog as a way to track potential server errors, but Owens said kernel bugs can crash a machine, so it doesn't help nearly as much as netconsole. He added that Facebook had a system in the past for monitoring that used syslog-ng, but it was less than 60 percent reliable. In contrast, Owens stated netconsole is highly scalable and can handle enormous log volume with greater than 99.99 percent reliability. "Netconsole is fanatically easy to deploy," Owens said. "Configuration is independent of the hardware and by definition you already have a network."

Android 7.0 Nougat

  • Android 7.0 Nougat review—Do more on your gigantic smartphone
    After a lengthy Developer Preview program starting in March, the final version of Android 7.0 (codenamed "Nougat") is finally launching today. The OS update will slowly begin to rollout to devices over the next few weeks. This year, Google is adding even more form factors to the world's most popular operating system. After tackling watches, phones, tablets, TVs, and cars, Nougat brings platform improvements aimed at virtual reality headsets and—with some help from Chrome OS—also targets laptops and desktops.
  • Google Android 7.0 Nougat Review – Surprisingly Uninspiring
    Since the past couple of years, Android updates have hit a concrete wall. Feature additions have gotten pretty mundane while focus on under the hood changes have become key for Google. Obviously, that’s a good thing, for some folks out there, but it’s a approach that doesn’t stand the test of time really very well. Users get frustrated after seeing the same thing over and over again. Same is absolutely true when you compare Android 7.0 Nougat directly with its predecessor, Android 6.0 Marshmallow.
  • Android 7.0 Nougat review: longer battery life and faster operation
    Android 7.0 Nougat is the new version of Google’s mobile operating system, used by billions of devices around the world. It features longer battery life, improved multitasking and smarter notifications in a slimmed down and refined Android experience – following on the work done in last year’s version 6 Marshmallow It is faster, more polished and a subtly-better experience all-round. Apps install more quickly, the OS can be smaller in size and updates to Android can be installed on the fly, without having to wait for 10 minutes while it reboots, if you have a new device. The new Vulcan API graphics system is also baked in for better gaming performance and Nougat will support Google’s Daydream virtual reality system, eventually. Nougat is not, however, a major visual overhaul of Android. Those that have used Marshmallow on any of Google’s Nexus smartphones or devices with little in the way of modification to Android, such as the OnePlus 3, will instantly recognise it.
  • The Best New Features In Android 7 Nougat
    The OS formerly known as Android N is officially out today for a range of Nexus phones.

  • How to measure your community's health
    How do you measure the health of your community, identify problems, and track progress towards your goals? What should you be measuring? Last month we discussed vanity metrics, those metrics that might sound impressive on the surface, but ultimately give you little insight or guidance to improve the health and well-being of your community. This naturally begs the question: What should you be measuring? And as I mentioned last month, the obvious but annoying answer: It depends. The first and foremost dependency relates to the nature of your community and where you and your members want it to go.

  • Walmart, Comcast Hasten Innovation, Improve Agility With OpenStack
    As new technologies like applications and programming languages are introduced, it's important for companies to remain flexible and fast enough to adapt, which is why Walmart and Comcast have embraced OpenStack. By adopting OpenStack solution OneOps, Walmart doesn't have to spend unnecessary time writing code or automating new processes in order to keep up with new technologies, Andrew Mitry, OpenStack Lead at Walmart, explained today at OpenStack East 2016. Walmart already uses more than 3,000 applications and services and has more than 170,000 cores in more than 30 regions, with more than 60 Open Source products that are deployed more than 40,000 times each month. With OneOps, Walmart can automate low-level processes like load balance and firewalls using OneOps, which Mitry said frees up time and resources to manage more intricate processes that require manual oversight.
  • MySQL daddy Widenius: Open-source religion won't feed MariaDB
    MySQL daddy Monty Widenius has dismissed claims the MariaDB fork is veering away from open source. Rather, the chief technology officer of MariaDB corporation called his firm’s embrace of a commercial licence for part of MariaDB "critical" to delivering new revenue and for the continued development of open-source software. Widenius told The Register in an interview that he believes criticism of MariaDB’s commercial licence for its new database proxy sever, MaxScale 2.0, is motivated by a "religious" belief in free and open source software. Not that Widenius is against the belief per se, he told The Register, it’s just: "Religion doesn't put meat on the table."

FOSS in Government

  • Uganda eager to tap into open source
    Uganda's Ministry of ICT recently developed a FOSS (Free and Open Source Software) policy to regulate the deployment of open source software and use of open standards to accelerate innovation and develop local content. At the 7th African Conference on Free and Open Source Software (FOSS), organised in conjunction with Uganda's National Information Technology Authority (NITA-U) to encourage industry partnerships and uptake of OSS in East Africa, open software was recognised for its contribution to innovation. Frank Tumwebaze, Minister of ICT and National Guidance in Uganda, said, "Free and open software services will help my ministry to innovate better because it forms the platform (for) many of the innovative ideas. Free and open source software in Uganda is certainly something we have been talking about and I am sure we will do so even more in the next few days. Some of the things Uganda has put in place to harness the benefit from free and open source software include a Software Strategy and Policy in accordance with the United Nations Conference on Trade and Development's (UNCTAD) Trade, Services and Development expert meeting's determination that free and open source software is an inseparable component of the global technology ecosystem."
  • Ireland's govt IT: Recession and job cuts forced us to adapt
    Ireland was hit hard by the global financial crunch of 2007 and 2008. It was the first of the EU member states to slip into recession immediately following the bursting of the economic bubble. As the economy contracted, banks faced default and government debt increased, with Ireland eventually taking an €67.5bn loan from the European Commission, European Central Bank (ECB) and the International Monetary Fund (IMF) Falling tax income and the need to bail out banks saw the Irish government spending in other areas of public life. The government had introduced the Public Sector Recruitment Embargo in 2009, which stopped hiring of all civil servants across government and cut pay and pensions – in return for a promise of no compulsory redundancies.
  • Oh! The Horror! Ireland Stays Enslaved To MS
    For 15 years or so, I was in those same financial straits in schools where I taught and GNU/Linux and FLOSS (Free/Libre Open Source Software) was the obvious solution. Obviously, one is better off to have IT for all rather than paying monopolistic prices for IT for a few. In schools, that meant extending the life of IT, elimination of malware and re-re-reboots, freedom from paper, freight for paper, storage for paper, … For governments freedom from lock-in to M$ and “friends” saved huge sums which could have been better spent on hardware or employees. Sigh.
