• The openSUSE Leap 15.1 update experience

  My desktop is a HP Pavilion Power 580-146nd. This is a midsize PC with an AMD Ryzen 5 1400 CPU, an AMD Radeon RX 580 GPU, 16 GB of RAM, a 128 GB M.2 SSD and a 1 TB 7200rpm HDD.

  I used the same USB thumbstick. After selecting ‘Update’ from the boot menu, the whole screen went black. And then nothing happened. Since I have installed openSUSE many times before, I quickly realized that this must be a graphics issue. I used ‘nomodeset’ in the past to get around that issue. This causes the installer to go back to the most basic graphics settings but it also means I could finish the update.

  It used to be a lot easier to edit the boot options. However, this is now hidden. This post on Stack Exchange (2) gives a great explanation how to enable nomodeset, both as a one-time option and as a permanent option.

  For the permanent enablement of nomodeset I know an easier way: in YaST look for the module ‘Boot Loader’ and in the Kernel Parameters tab, you can edit the boot command. This was the route that I took to make nomodeset a permanent boot setting.

• Getting further with Btrfs in YaST

  Since the YaST team rewrote the software stack for managing the storage devices, we have been adding and presenting new capabilities in that area regularly. That includes, among other features, the unpaired ability to format and partition all kind of devices and the possibility of creating and managing Bcache devices. Time has come to present another largely awaited feature that is just landing in openSUSE Tumbleweed: support for multi-device Btrfs file systems.

  As our usual readers surely know, Btrfs is a modern file system for Linux aimed at implementing advanced features that go beyond the scope and capabilities of traditional file systems. Such capabilities include subvolumes (separate internal file system roots), writable and read-only snapshots, efficient incremental backup and our today’s special: support for distributing a single file system over multiple block devices.

• openSUSE's YaST Now Supports Multi-Device Btrfs Setups

  For those wanting to install openSUSE Tumbleweed on a system where a single Btrfs file-system spans multiple block devices, that's now easily possible with the latest YaST. This includes the abilities for just a simple file-system spanning multiple devices to data duplication to the various RAID levels natively supported by Btrfs.

• An application a year to an application a week on AWS

  At the recent SUSECON conference in Nashville, Ryan Niksch from AWS discussed how shifting the focus from writing code to deploying applications to production has become more critical as business agility tops the list of customer requirements. He then introduces the benefits of Cloud Foundry in general, and SUSE Cloud Application Platform specifically, including the AWS service broker; its benefits are that it is a containerized distribution of Cloud Foundry that can very quickly and easily be deployed to AWS using a Quick Start template.

• SUSE Linux Enterprise 12 Service Pack 5 Beta 1

• A demo based introduction to SUSE Cloud Application Platform

  At the recent SUSECON conference in Nashville, Peter Andersson and Peter Lunderbye from SUSE demonstrated SUSE Cloud Application Platform, including pushing your first app, buildpacks: what are they and how they can be utilised, scaling and how easy the platform makes it, and how to improve resiliency and availability of your app.
  SUSE has posted all recorded talks from SUSECON on YouTube. Check them out if you want to learn more about what SUSE has to offer. We’re not just Linux anymore! I’ll be posting more SUSE Cloud Application Platform talks here over the coming days.

• Enabling Discoveries with AI and HPC (and the Rise of Helium)

  This week I am attending the International Supercomputing conference in Frankfurt, and I am in awe of the scientists and researchers that are here and their ability to dig in and understand super complex problems in very specialized areas.  While I am humbled by the world-changing work represented at a conference like this, I am also honored to be playing a small part in their success.  With the next iteration of SUSE Linux Enterprise High Performance Computing 15 SP1, we’ve expanded and refreshed our bundle of popular HPC tools and libraries that we make available along with every subscription to our SLE HPC operating system.

• No Downtime Upgrade for Red Hat Data Grid on Openshift

  In a blog post I wrote on the Red Hat Developer’s Blog, I wrote about multiple layers of security available while deploying Red Hat Data Grid on Red Hat Openshift. Another challenging problem I see for customer is performing a no downtime upgrade for Red Hat Data Grid images (published on Red Hat Container Catalog). That’s what we’re going to tackle in this post.

  If you’re new to it, Red Hat Data Grid is an in-memory, distributed, NoSQL datastore solution. With it, your applications can access, process, and analyze data at in-memory speed designed to deliver a superior user experience compared to traditional data stores like relational databases. In-memory Data Grids have a variety of use cases in today’s environments, such as fast data access for low-latency apps, storing objects (NoSQL) in a datastore, achieving linear scalability with data distribution/partitioning, and data high-availability across geographies.

• World domination with cgroups in RHEL 8: welcome cgroups v2!

  One of the great things about open source development is that features can be designed and implemented organically and grow and change as needed. However, a drawback is that this methodology can sometimes lead to a hot mess and uncomfortable technical debt.

  In the case of cgroups v1, as the maintainer Tejun Heo admits, "design followed implementation," "different decisions were taken for different controllers," and "sometimes too much flexibility causes a hindrance."

  In short, not all of the controllers behave in the same manner and it is also completely possible to get yourself into very strange situations if you don’t carefully engineer your group hierarchy. Therefore, cgroups v2 was developed to simplify and standardize some of this.

  Let’s take a look at how the two versions are different. I’m going to show two different diagrams - controllers are in yellow blocks and cgroup directories have a grey background.

• Are We Ready to Ditch the Data Center? [Ed: Perpetuating the myth that when you outsource all business functions to the Pentagon through its partners the servers just vanish and cease to exist]

  Over the past few decades, organizations have come to rely on their own data centers to run business applications, network their users together and for data storage. Initially, these data centers were largely hardware-centric.In the early days, a mainframe and terminals were the order of the day, before we moved onto the RISC/UNIX era, followed more recently by the server sprawl period of commodity X86 servers.
  But now, the whole concept of an organization-owned data center is going through a radical change. It started with virtualization, which separated the direct relationship between application software and the underlying hardware infrastructure. This helped improve server utilization, efficiency, and provisioning speed. The next step towards an even greater level of abstraction is the move to a software-defined infrastructure (SDI), including compute, storage and networking.

I’ve been using computers for as long as I can remember, playing Solitaire, The Settlers, and other simple DOS games, because that’s what my parents and grandma liked to play. I started with Win95, 98, and 2000, before learning about Linux.

My interest in design was sparked by the original iPhone icons, which I loved. In contrast with my hatred toward the Faenza icon theme, both have fairly similar style yet widely different results. That’s how I began exploring and learned from there.

Correspondingly, my Linux journey started back in 2007 when my dad showed me Ubuntu, and just like what I did with Windows 2000 before, my pastime became installing and reinstalling Linux alongside Windows in different configurations (I apparently was consumed by the concept of installation and configuration, which might explain my YaST obsession?).

Later in 2010, I had a tough time with a machine that wouldn’t take any distro with the exception of openSUSE (although it did end up with a few Linuxrc errors). Besides, I really liked its GNOME 2 config back then; it was really user friendly yet powerful. I gave KDE a shot but to this day I never really liked it.
