  • TUXEDO Computers to Develop Own Ubuntu-Based Linux Distro Using Xfce Desktop

    Vinzenz Vietzke of TUXEDO Computers announced today that the German electronics manufacturer, which is known for selling laptops and desktop computers that ship pre-loaded with Linux, created their own distro.

    The news comes just a week after System76 computer reseller announced Pop!_OS as their own GNU/Linux distribution based on Ubuntu and the GNOME desktop environment, and it now looks like TUXEDO Computers follow suit and announce TUXEDO Xubuntu, their own Xubuntu-based distro, which will power all of their computers in the near future.

  • Developer Replaces His MacBook Pro with a Raspberry Pi 3 Computer for One Week

    Node.js expert and backend software engineer Pierre-Gilles Leymarie has recently lost his precious MacBook Pro in a taxi in Paris, and since he didn't have any other computer at home, he decided to give Raspberry Pi a try.

    MacBook Pro is a powerful computer, running Apple's state-of-the-art macOS operating system, yet Pierre-Gilles Leymarie was using it for coding on his Gladys home assistant based on a Raspberry Pi single-board computer using software like VS Code, Node.js and MySQL, along with some other developer-related tools.

    Since Pierre-Gilles Leymarie was very familiar to Raspberry Pi, as it own a few of them at home to hack on his Gladys project, setting up a Raspberry Pi 3 SBC and convert it into a full-featured desktop PC was quite easy to do by installing Raspbian Jessie, an old wireless mouse, a very old USB keyboard, and a 22-inch HDMI LCD.

  • Post-mortem: Extended Deployment time on June 30, 2017

    On June 30, 2017 we had an extended deployment time of roughly 45 minutes for our reference server because of a couple of problems with one of the data migrations. We implemented a new feature, user notifications via RSS, that included a migration of data in our database. This migration was broken, causing this deployment to go terribly wrong.

    The frontend team afterward met to do a post-mortem to identify the problems, solutions and possible take aways for the future. This is the first post-mortem meeting we held, hopefully but not likely the last. Here goes the report.

  • Life full-time at Red Hat

    I had been talking with my manager, Paul Frields, for some time about transitioning to full-time after college. Long story short, the timing so happened to work out that I could be brought on slightly before I'm officially done with college. To that end, I am planning to finish college out part-time from here on out. I still have to take an Ethics course to finish my computer science degree, and I still have some math classes left, for my math degree. I plan on going <= 6 credit hours per semester until I am done, however long that takes.

  • Progress report for period June 12th - June 25th

    During the coding period, I discovered that MetaDisplay, main GObject of Mutter had a lot of X11 specific fields, so I had to move them into something else, which we (mentors and myself) decided to call MetaX11Display. A lot of code had to be modified, and that had to be carefully approached, so nothing got broken in the process. The "coding" I had done was just moving stuff around, between files, adjusting for new structure fields, and so on. It was, I might say, a rather boring experience. But, someone had to do it, as it is a requisite for all of my future work. Note that even at the moment of writing, all of X11 specifics have not been ironed out. While trying to efficiently split MetaDisplay, I stumbled upon MetaScreen, a structure which previously used to contain reference to X Screen it was managing. The comments in the code pointed out that, while Mutter used to contain more than one X Screen, nowadays it manages only one. So, again, we realized that structure needs to be split somehow, since it contains (as expected) lot of X11 specifics, but also some code that can be used for Wayland environment. The decision was made to move the fields into MetaDisplay and MetaX11Display, depending in which environment it might be useful. Sadly, I did not get around to start disassembling the screen management code in this period. So, that's what my next adventure will be all about. All of the work that was done is available on my Github repository [1].

  • Distributions are becoming irrelevant: difference was our strength and our liability

    For someone that has spent the past thirteen years defining himself as a developer of a Linux distribution (whether I really am still a Gentoo Linux developer or not is up for debate I’m sure), having to write a title like this is obviously hard. But from the day I started working on open source software to now I have grown a lot, and I have realized I have been wrong about many things in the past.

    One thing that I realized recently is that nowadays, distributions lost the war. As the title of this post says, difference is our strength, but at the same time, it is also the seed of our ruin. Take distributions: Gentoo, Fedora, Debian, SuSE, Archlinux, Ubuntu. They all look and act differently, focusing on different target users, and because of this they differ significantly in which software they make available, which versions are made available, and how much effort is spent on testing, both the package itself and the system integration.

  • SUSE Expands Container Management and Deployment Capabilities

    Like most Linux vendors today, SUSE is keeping busy updating it portfolio to support the growing demand for container management and services. So far this month, SUSE has announced two different efforts to improve its container portfolio.

    On June 27, SUSE announced its SUSE Manager 3.1 update, which provides new capabilities for organizations to manage software across both container and cloud infrastructure. SUSE Manager has been part of the SUSE portfolio since 2011, when the company was still part of Novell.

    "SUSE Manager's new container management and compliance capabilities will enable customers to automate orchestration and provisioning of their container-based services while ensuring container compliance from the same tool they are already using to manage their Linux infrastructure," Mary Johnston Turner, research vice president for Enterprise System Management Software at IDC, said in a statement.

  • OECD: ‘Create incentives for reuse of open data’

    The Organisation for Economic Co-operation and Development (OECD) is urging Europe’s governments to create incentives for public sector organisations and others to use open data. A good way for governments to promote sharing and reuse of data, and to improve public administration, is the creation of data-driven eGovernment services, says Barbara Ubaldi, Head of Unit, Digital Government and Open Data at the OECD.

  • Manjaro Linux 17.0.2 Arch-based operating system is here with GNOME, KDE, and Xfce

    Many Linux snobs push the Arch operating system as the greatest thing since sliced bread. In fact, some members of the Arch community (not all of them) can be downright mean and unpleasant to non-users. Not using Arch? Ugh. Peasant! In reality, while Arch is a fine OS (stable and fast), it can be very hard to install and set up, and quite frankly, often not worth the hassle. People have lives to live, and sometimes it is easy to forget that an operating system and associated computer are tools -- not a religion.

  • [Older] The Turtlebot 3 has launched

    If you’re familiar with ROS (Robot Operating System), chances are you’re also familiar with the Turtlebot. The first version of the Turtlebot was created back in 2010 to serve as an inexpensive platform for learning ROS. This was followed in 2012 by the Turtlebot 2, which has since become the reference platform for learning ROS. We have a number of them here at Canonical, and we love them, although we have one issue with them: they’re just a tad too big. Taking them on a plane requires one to decide what one loves more, one’s belongings, or the Turtlebot, and to check the other.

  • Security-Focused Purism Librem 13 & 15 Linux Laptops Go Mainstream with Qubes OS

    Purism, the social purpose corporation focused on designing and manufacturing privacy-conscious hardware and software products, announced the general availability of their security-focused Purism Librem 13 and 15 laptops.

    Until recently, both Purism Librem 13 and Librem 15 laptops were available only as made-to-order, which means that those who wanted to purchase either model would have to order it first and then wait a few months until the device arrived. And now, the company finally managed to scale the production to hold inventory of the laptops.

  • Alioth moving toward pagure

    Since 2003, the Debian project has been running a server called Alioth to host source code version control systems. The server will hit the end of life of the Debian LTS release (Wheezy) next year; that deadline raised some questions regarding the plans for the server over the coming years. Naturally, that led to a discussion regarding possible replacements.

    In response, the current Alioth maintainer, Alexander Wirt, announced a sprint to migrate to pagure, a free-software "Git-centered forge" written in Python for the Fedora project, which LWN covered last year. Alioth currently runs FusionForge, previously known as GForge, which is the free-software fork of the SourceForge code base when that service closed its source in 2001. Alioth hosts source code repositories, mainly Git and Subversion (SVN) and, like other "forge" sites, also offers forums, issue trackers, and mailing list services. While other alternatives are still being evaluated, a consensus has emerged on a migration plan from FusionForage to a more modern and minimal platform based on pagure.

  • Understanding Xwayland - Part 1 of 2

    In this week’s article for my ongoing Google Summer of Code (GSoC) project I planned on writing about the basic idea behind the project, but I reconsidered and decided to first give an overview on how Xwayland functions on a high-level and in the next week take a look at its inner workings in detail. The reason for that is, that there is not much Xwayland documentation available right now. So these two articles are meant to fill this void in order to give interested beginners a helping hand. And in two weeks I’ll catch up on explaining the project’s idea.

    [...]

    In the second part next week we’ll have a close look at the Xwayland code to see how Xwayland fills its role as an Xserver in regards to its X based clients and at the same time acts as a Wayland client when facing the Wayland compositor.

Oracle changes heart on Java EE

  • Oracle opens up Java EE
    Oracle continues to make progress Java EE 8, the enterprise edition for the Java platform, and moving forward it would like to advance Java EE within a more open and collaborative community. Specifications are nearly complete and the Java team expects to deliver the Java EE 8 reference implementation this summer. As the delivery of Java EE 8 approaches, Oracle believes they have the ability to rethink how Java EE is developed in order to “make it more agile and responsive to changing industry and technology demands.”
  • Oracle considers moving Java EE to an open source foundation
    With the finalization of the Java EE 8 platform on the horizon, Oracle on Thursday said it's considering moving Java Enterprise Edition technologies to an open source foundation. The move, Oracle said in a blog post, "may be the right next step, in order to adopt more agile processes, implement more flexible licensing, and change the governance process."
  • Oracle doesn't want Java EE any more
    Oracle wants to end its leadership in the development of enterprise Java and is looking for an open source foundation to take on the role. The company said today that the upcoming Java EE (Enterprise Edition) 8 presents an opportunity to rethink how the platform is developed. Although development is done via open source with community participation, the current Oracle-led process is not seen agile, flexible, or open enough. ”We believe that moving Java EE technologies to an open source foundation may be the right next step, to adopt more agile processes, implement more flexible licensing and change the governance process,” Oracle said in a statement.
