  • A Native Kubernetes Operator Tailored for Cloud Foundry

    At the recent Cloud Foundry Summit in Philadephia, Troy Topnik of SUSE and Enrique Encalada of IBM discussed the progress being made on cf-operator, a project that’s part of the CF Containerization proposal. They show what the operator can do and how Cloud Foundry deployments can be managed with it. They also delve deeper, and talk about implementation techniques, Kubernetes Controllers and Custom Resources. This is a great opportunity to learn about how Cloud Foundry can work flawlessly on top of Kubernetes. Cloud Foundry Foundation has posted all recorded talks form CF Summit on YouTube. Check them out if you want to learn more about what is happening in the Cloud Foundry world! I’ll be posting more SUSE Cloud Application Platform talks here over the coming days. Watch Troy and Enrique’s talk below:

  • Redefining RHEL: Introduction to Red Hat Insights

    At Red Hat Summit we redefined what is included in a Red Hat Enterprise Linux (RHEL) subscription, and part of that is announcing that every RHEL subscription will include Red Hat Insights. The Insights team is very excited about this, and we wanted to take an opportunity to expand on what this means to you, and to share some of the basics of Red Hat Insights. We wanted to make RHEL easier than ever to adopt, and give our customers the control, confidence and freedom to help scale their environments through intelligent management. Insights is an important component in giving organizations the ability to predict, prevent, and remediate problems before they occur.

  • OpenShift Commons Briefing: OKD4 Release and Road Map Update with Clayton Coleman (Red Hat)

    In this briefing, Red Hat’s Clayton Coleman, Lead Architect, Containerized Application Infrastructure (OpenShift, Atomic, and Kubernetes) leads a discussion about the current development efforts for OKD4, Fedora CoreOS and Kubernetes in general as well as the philosophy guiding OKD 4 develpoment efforts. The briefing includes discussion of shared community goals for OKD4 and beyond and Q/A with some of the engineers currently working on OKD. The proposed goal/vision for OKD 4 is to be the perfect Kubernetes distribution for those who want to continuously be on the latest Kubernetes and ecosystem components combining an up-to-date OS, the Kubernetes control plane, and a large number of ecosystem operators to provide an easy-to-extend distribution of Kubernetes that is always on the latest released version of ecosystem tools.

  • OpenStack Foundation Joins Open Source Initiative as Affiliate Member

    The Open Source Initiative ® (OSI), steward of the Open Source Definition and internationally recognized body for approving Open Source Software licenses, today announces the affiliate membership of The OpenStack Foundation (OSF). Since 2012, the OSF has been the home for the OpenStack cloud software project, working to promote the global development, distribution and adoption of open infrastructure. Today, with five active projects and more than 100,000 community members from 187 countries, the OSF is recognized across industries as both a leader in open source development and an exemplar in open source practices. The affiliate membership provides both organizations a unique opportunity to work together to identify and share resources that foster community and facilitate collaboration to support the awareness and integration of open source technologies. While Open Source Software is now embraced and often touted by organizations large and small, for many just engaging with the community—and even some longtime participants—challenges remain. Community-based support and resources remain vital, ensuring those new to the ecosystem understand the norms and expectations, while those seeking to differentiate themselves remain authentically engaged. The combined efforts of the OSI and the OSF will compliment one another and contribute to these efforts.

Operating system can be completely customized by the administrator using this feature (donors version only); screen can be rotated via the graphical admin interface: normal, inverted, left, right (donors version only);

OSS: Databases Microconference, Overview of SELF 2019, Linux Security Summit North America, EuroPython

  • Databases Microconference Accepted into 2019 Linux Plumbers Conference

    We are pleased to announce that the Databases Microconference has been accepted into the 2019 Linux Plumbers Conference! Linux plumbing is heavily important to those who implement databases and their users who expect fast and durable data handling. Durability is a promise never to lose data after advising a user of a successful update, even in the face of power loss. It requires a full-stack solution from the application to the database, then to Linux (filesystem, VFS, block interface, driver), and on to the hardware. Fast means getting a database user a response in less that tens of milliseconds, which requires that Linux filesystems, memory and CPU management, and the networking stack do everything with the utmost effectiveness and efficiency.

  • Ten Years of "Linux in the GNU/South": an Overview of SELF 2019

    The tenth annual SouthEast LinuxFest (SELF) was held on the weekend of June 14–16 at the Sheraton Charlotte Airport Hotel in Charlotte, North Carolina. Still running strong, SELF serves partially as a replacement for the Atlanta Linux Showcase, a former conference for all things Linux in the southeastern United States. Since 2009, the conference has provided a venue for those living in the southeastern United States to come and listen to talks by speakers who all share a passion for using Linux-based operating systems and free and open-source software (FOSS). Although some of my praises of the conference are not exclusive to SELF, the presence of such a conference in the "GNU/South" has the long-term potential to have a significant effect on the Linux and FOSS community. Despite facing several challenges along the way, SELF's current success is the result of what is now ten years of hard work by the conference organizers, who currently are led by Jeremy Sands, one of the founding members of the conference. Scanning through the materials for SELF 2019, however, there is no mention that this year's conference marked a decade of "Linux in the GNU/South". It actually wasn't until the conference already was over that I realized this marked SELF's decennial anniversary. I initially asked myself why this wasn't front and center on event advertisements, but looking back on SELF, neglecting questions such as "how long have we been going?" and instead focusing on "what is going on now?" and "where do we go from here?" speaks to the admirable spirit and focus of the conference and its attendees. This focus on the content of SELF rather than SELF itself shows the true passion for the Linux community rather than any particular organization or institution that benefits off the community. Another element worthy of praise is SELF's "all are welcome" atmosphere. Whether attendees were met with feelings of excitement to return to an event they waited 362 days for or a sense of apprehension as they stepped down the L-shaped hall of conference rooms for the first time, it took little time for the contagious, positive energy to take its effect. People of all ages and all skill levels could be seen intermingling and enthusiastically inviting anybody who was willing into their conversations and activities. The conference talks, which took all kinds of approaches to thinking about and using Linux, proved that everybody is welcome to attend and participate at the event.

  • Linux Security Summit North America 2019: Schedule Published

    This year, there are some changes to the format of LSS-NA. The summit runs for three days instead of two, which allows us to relax the schedule somewhat while also adding new session types. In addition to refereed talks, short topics, BoF sessions, and subsystem updates, there are now also tutorials (one each day), unconference sessions, and lightning talks.

LibreOffice: “Tip-Of-The-Day” (Design), LibreOffice Quality Assurance and LibreOffice Appliances

  • Easyhacking: How to create a new “Tip-Of-The-Day” dialog

    LibreOffice is an application with a large number of expert features, and though aimed to be easy to use there are always surprising shortcuts to achieve a goal. We post every day a tip on Twitter, and with the upcoming release 6.3 there will be also a tip-of-the-day messagebox when you start the program. This post aims to show how such a simple messagebox can be implemented (the complete patch is here).

  • bibisect-win64-6.4 is available for cloning!

    The LibreOffice Quality Assurance ( QA ) Team is happy to announce the bisect repository from libreoffice-6-3-branch-point to latest master for Windows is available for cloning at Gerrit. As a novelty, it’s the first time the bisect repository for Windows is built for 64 bits instead of 32 as in previous repositories. Future repositories will be built for 64 bits as well.

  • LibreOffice Appliances project (GSoC 2019)

    So I finally managed to build LibreOffice for armv7 and I have LibreOfficeDev on my TV screen right now. There’s a link to build instructions above and I’ll update it with the autogen flags I used. They’re somewhat arbitrary but yeah.

Andy Wingo: fibs, lies, and benchmarks

I collected these numbers on my i7-7500U CPU @ 2.70GHz 2-core laptop, with no particular performance tuning, running each benchmark 10 times, waiting 2 seconds between measurements. The bar value indicates the median elapsed time, and above each bar is an overlayed histogram of all results for that scenario. Note that the y axis is on a log scale. The 2.9.3* version corresponds to unreleased Guile from git. Good news: Guile has been getting significantly faster over time! Over decades, true, but I'm pleased. where are we? static edition How good are Guile's numbers on an absolute level? It's hard to say because there's no absolute performance oracle out there. However there are relative performance oracles, so we can try out perhaps some other language implementations. First up would be the industrial C compilers, GCC and LLVM. We can throw in a few more "static" language implementations as well: compilers that completely translate to machine code ahead-of-time, with no type feedback, and a minimal run-time. Read more
