Ubuntu

Ubuntu developers today have announced a "tech preview" of their new text-based installer for Ubuntu Server.

Earlier this month we heard of a new Ubuntu Server installer being worked on and it was dubbed Subiquity. Now that the 17.04 release has cleared and 17.10 development begun, the new installer was announced as a tech preview for Ubuntu Server 17.04.

Mathieu Trudel-Lapierre announced, "During the 17.04 development cycle, the Ubuntu Foundations team has been working on a new experimental installer for servers. We are now ready to get feedback from a wider audience."

The new replication features in MySQL 8

Filed under
Server
OSS

This year at the Percona Live open source database conference, I will present a talk on the latest replication features in MySQL 8.0.

It was a huge amount of work to get the MySQL Group Replication plugin out with MySQL 5.7.17. Group Replication is a new plugin that gives the user some nice replication properties by resorting to group communication and state machine replication. This makes the system able to protect data against split brain situations, enables fault-tolerance and high availability, and provides coordination between servers committing transactions that change the data.

In addition to Group Replication, the team has also invested quite a bit on core replication features. Some of these features were already released, and others will be released at some point in time in a MySQL Development Milestone Release (DMR).

  • Open Source Tools for Enterprise Data Science
  • Open for business: Hortonworks aims for open source profitability

    It used to be the Hadoop Summit, but the strategic focus at Hortonworks the enterprise-ready open source Apache Hadoop provider, has evolved. So, this year it was renamed DataWorks Summit. The company now encompasses data at rest (the Hadoop Data Platform now in version 2.6), data in motion (the Hadoop Data Flow) and data in the cloud (the Hadoop Data Cloud). Hortonworks aims to become a multi-platform and multi-cloud company. The focus is on the data in data driven organisations. Just a few years ago Hortonworks connected with IT architects. Today it’s launching conversations with lines of business and chief marketing officers.

  • What's new in OpenStack Ocata

    OpenStack Ocata has now been out for a little over a month and we're about to see the first milestone of the Pike release. Past cycles show that now's about the time when people start looking at the new release to see if they should consider moving to it. So here's a quick overview of what's new in this release.

  • Research: OpenStack user satisfaction ratings drop, as adoption of the open source cloud rises

  • Mirantis enters the Kubernetes game and ups its OpenStack play

    The Sunnyvale, Calif. company is doing this by launching a new single integrated distribution of OpenStack and Kubernetes: Mirantis Cloud Platform (MCP) 1.0. This new release also offers a unique build-operate-transfer delivery model.

  • Mirantis launches its new OpenStack and Kubernetes cloud platform

    Mirantis, one of the earliest players in the OpenStack ecosystem, today announced that it will end-of-life Mirantis OpenStack support in September 2019. The Mirantis Cloud Platform, which combines OpenStack with the Kubernetes container platform (or which could even be used to run Kubernetes separately), is going to take its place.

    While Mirantis is obviously not getting out of the OpenStack game, this move clearly shows that there is a growing interest in the Kubernetes container platform and that Mirantis’ customers are now starting to look at this as a way to modernize their software deployment strategies without going to OpenStack. The new platform allows users to deploy multiple Kubernetes clusters side-by-side with OpenStack — or separately.

  • IBM Brings Anaconda Open Data Science Platform to its Cognitive Systems

    IBM is working with Continuum Analytics to offer the latter’s Anaconda open data science platform as part of IBM’s Cognitive Systems. Anaconda will also integrate with IBM’s PowerAI software for machine learning and deep learning.

  • Hadoop: the rise of the modern data lake platform

    Hadoop, while it may be synonymous with big data, and while it may be free to access and work with, engineering teams globally will admit that behind every Hadoop undertaking is a major technical delivery project.

    Failures are so commonplace that even the experts don’t have great expectations of 2017: at the recent Gartner Data & Analytics Summit in Sydney, research director Nick Heudecker claimed that 70% of Hadoop deployments in 2017 will either fail to deliver their estimated cost savings or their predicted revenue.

  • The best minds in open source gather at OpenStack Summit Boston

    In my keynote address a year ago at the OpenStack Summit Austin, I offered the OpenStack community an ultimatum. First, I described how our world was exploding with connected devices (50 billion by 2020) and that 400 million new servers would be needed to process and store that data, which creates a massive challenge for those of us in the infrastructure business. How will we meet the needs of users at that scale?

  • What will OpenStack R be Named?

    That time again, when members of the OpenStack community vote on the release name for the upcoming series of milestones. The current release is called Ocata, the next release is code named Pike and is set to debut August 28.

  • System76 wants to build its own hardware for its Linux-based computers
    System76 is building up quite a name for itself, being one of a very limited number of companies selling only computers running Linux-based operating systems. Now the aim is to branch out; System76 wants to design and build its own hardware, while representing the open source community as it does so. At the moment, the hardware used in System76 systems is outsourced, but in the future this will change. The company says that it is moving into phase three of its development cycle, and this "moves product design and manufacturing in house." And you should set your expectations high: "We're about to build the Model S of computers. Something so brilliant and beautiful that reviewers will have to add an 11 to their scores."
  • AppCenter Spotlight: Beta Testers
    Over the past month we’ve been beta testing the new AppCenter with a number of developers, from elementary OS contributors to backers of our Indiegogo campaign. After testing out the submission process and getting some apps into the store (and seeing rapid updates!), I wanted to take a moment to highlight some of the first apps.
  • elementary OS to get improved AppCenter, showing off a few new applications
    I have to hand it to the elementary OS guys, they have a massive focus on design and it does look quite incredible. It is easily one of the best looking Linux distributions, which I do admire. Their new AppCenter, for example, looks extremely clean and clear.

Beijing Zoo is No Place for Pandas

Pandas in Beijing Zoo
Photo credit: Nick Hopkins

I am a Panda lover. I work as a support engineer in an I.T company here in the United Kingdom. Most of my spare time is spent watching different Panda videos -- both old and new videos. Basically, it is my therapy; a 'stress release' for me. I find them to be adorable and precious creatures. As a matter of fact, I would like to volunteer to come to Sichuan. I want to experience and feel what it's like to be a Panda keeper, to be able to interact with them for real. The Panda is China's National Treasure, so it's a shame to watch the Panda videos from Beijing zoo, as the place is disgusting and not ideal for Pandas to live in (and for sure for all the rest of the animals who unfortunately got stuck in this prison cell).

The place looks like a ghost town. Lifeless and languished. Knowing that Pandas wear a thick fur on their body, can you imagine what it feels for them in 30C or 35C (summer temperature)? What it probably feels like all the time? Come on, if you really care, you must do something now, otherwise these Pandas will die. Please bring them back to their sanctuary where they really belong.

Linux 4.11 File-System Tests: EXT4, F2FS, XFS & Btrfs

With the Linux 4.11 kernel potentially being released as soon as today, here are some fresh benchmarks of Btrfs / EXT4 / F2FS / XFS on a solid-state drive and comparing the performance of 4.11 Git back to Linux 4.9 and 4.10. For those wondering if the block/file-system changes of Linux 4.11 have any impact on EXT4/F2FS/XFS/Btrfs for common I/O workloads or how these file-systems are comparing on this latest kernel, here are some benchmarks.
