Maintaining SUSE Linux support during the pandemic

Filed under
SUSE

The global pandemic and resulting government shelter-in-place or quarantine measures to limit the spread of the COVID-19 virus have shifted the priorities of IT organizations away from non-critical maintenance and upgrades. Unfortunately, the planned end of General Support date for SUSE Linux Enterprise Server (SLES) 12 Service Pack 4 happens to be in the middle of this crisis. At SUSE, we understand the strain the current environment is putting on your IT operations so we have an option to help you keep your systems supported and secure.
General Support for SLES 12 SP4 ends on June 30, 2020. Normally, organizations would either upgrade to a SLES service pack/version that still has full support or purchase up to 3 years of Long Term Service Pack Support (LTSS). Available today, organizations with current subscriptions of SUSE Linux Enterprise Server 12 SP4 are eligible to receive continued access to patches and updates in the LTSS repositories free of charge for 3 months starting July 1, 2020, through September 30, 2020. Platforms included in this offer are x86-64 and IBM Z/LinuxOne. This gives IT teams more time to complete upgrade plans and evaluations at a time when staffing is limited and the focus is on keeping the business operational.

Filed under
SUSE

The openSUSE community, contributors and release engineers for the project have entered into the release candidate phase today after the Build “665.2” snapshot was released for the upcoming openSUSE Leap “15.2” version.

In an email to the openSUSE Factory mailing list, Leap release manager Lubos Kocman recommended Beta and RC users using the “zypper dup” command in the terminal prior switching to the General Availability (GA).

The release candidate signals the package freeze for software that will make it into the distribution. Among some of the packages that are expected in the release are KDE’s Plasma “5.18” Long-Term-Support version, GNOME “3.34” and Xfce “4.14”. New package for Artificial Intelligence and data scientist will be in the release. The release will also contain the tiling Wayland compositor Sway, which is a drop-in replacement for the i3 window manager for X”11”. The DNF package manager has been rebased to version “4.2.19”, which brings many fixes and improvements. In addition, a lightweight C implementation of DNF called “Micro DNF” is now included. Pagure, which provides an easy, customizable, lightweight solution for setting up your own full-featured Git repository server, has been updated to version “5.10.0”. A list of some of the packages in Leap “15.2” can be found on the openSUSE Wiki.

  • SUSE turns open-source innovations into consumable business solutions

    While cutting-edge technologies may be the most appropriate for solving increasingly sophisticated business problems, companies need easy-to-use solutions. Simplifying modernization to facilitate its consumption by companies is one of the goals of the open-source software company SUSE.

    “We have to curate and prepare and filter all the open-source innovation that [enterprises] can benefit from, because that takes time to understand how that can match your needs and fix your problems,” said Dr. Thomas Di Giacomo (pictured, left), president of engineering and innovation at SUSE. “It is SUSE … working in the open-source projects, innovating them, but with customers in mind.”

  • SUSE, Elektrobit innovate at the edge

    Early stages of autonomous driving, the connected car, and electrification are no longer future ideas but realities on the road today, writes SUSE CEO Melissa di Donato.

    As the speed of innovation increases across the automotive industry, vehicles are now as much software platforms as chassis and engines. This fundamental shift away from hardware dominated to software-defined vehicles means there is a need to completely rethink the customer experience that the future best-selling vehicles need to deliver.

  • Cloud based workers for openQA

    openQA workers, which run the tests, are generally on the same network as the openQA web UI server which is fine most of the time, but if some additionnal hardware must be added, they must be sent physically and only few people can take care of it, which can be problematic. One solution to this problem is to use cloud based machines, which are by definition on a separate network and accessible through Internet.

    The good news is openQA supports such setups by using a local cache service on the worker. This service downloads the assets (ISO, HDD images, etc.) on demand through the openQA API via HTTPS, instead of using the legacy NFS mount method. Tests and needles are already in git repositories so they can be fetched from the remote git repositories directly instead of using them from the NFS share.

  • Moving SAP can be the start of digital realignment with SUSE capability

    For SAP users, the coming need to change hosting requirements to Linux is spurring many companies in the APAC region to reconsider their hosting options. They may decide to move from in-house, bare metal self-hosting, to public cloud providers, for example, as part of that migration.

  • Skopeo 1.0 released [Ed: Red Hat keeps outsourcing its work to a proprietary software trap controlled and exploited by Microsoft]

    I often talk about all of the new container tools that we have developed over the last few years, and often skim over Skopeo. But Skopeo was the first one, and really has some cool features.

    Skopeo is a tool for moving container images between different types of container storages. It allows you to copy container images between container registries like docker.io, quay.io, and your internal container registry or different types of storage on your local system. You can copy to a local container/storage repository, even directly into a Docker daemon.

The openSUSE Election Committee was tasked to find our whether 20% of the community are actually calling for the re-election.

We have at our disposal the Helios voting platform which we can use to register an "answer" from community members. Instead of running a vote with several answer options, we consulted among Election Officials, and agreed that there will be only one answer to select, which will represent a virtual signature, similar to like signing an electronic petition. That will allow us to effectively measure whether 20% of the community are petitioning for a re-election of the openSUSE Board.

SUSE

The coronavirus pandemic is rapidly changing technology. Remember when remote work was a radical idea? Not so much anymore. But Linux and cloud power SUSE. CEO Melissa Di Donato said in a recent survey of global IT leaders it was already deprioritizing the "legacy of complex applications, infrastructure, and processes."

Where are we going? To an outcome-focused IT approach relying on software-defined infrastructure, the hybrid cloud, and edge computing as fast as we can. And how fast is that? Within the next two years, according to 2,000 IT leaders and application developers who told SUSE and Insight Avenue.

  • Updated KDE Frameworks, Redis Arrive in Tumbleweed, Curl Gets New Experimental Feature

    KDE Frameworks 5.70.0 arrived in snapshot 202000511; these libraries for programming with Qt introduced a small font theme for Kirigami and improved icon rendering on multi-screen multi-dpi setups. KConfig added the standard shortcut for “Show/Hide Hidden Files” with the Alt+ keys. The text rendering bitmap package freetype2 updated to version 2.10.2 and dropped support for Python 2 in Freetype’s API reference generator; the version also supports Type 1 fonts with non-integer metrics by the new Compact Font Format engine introduced in FreeType 2.9. The 1.45.6 e2fsprogs package for maintaining the ext2, ext3 and ext4 file systems improved e2fsck’s ability to deal with file systems that have a large number of directories, such that various data structures take more than 2GB of memory; the new version uses better structure packing to improve the memory efficiency of these data structures. The libressl 3.1.1 package completed an initial Transport Layer Security 1.3 implementation with a completely new state machine and record layer. TLS 1.3 is now enabled by default for the client side, with the server side to be enabled in a future release. The changelog noted that the OpenSSL TLS 1.3 API is not yet visible/available. RubyGem had a plethora of packages updates in ; rubygem-fluentd 1.10.3 had some refactored code and enhancements like adding a set method to record_accessor. The rubygem-activerecord-6.0 6.0.3 package fixed support for PostgreSQL 11+ partitioned indexes and noted a recommendation in the changelog that applications shouldn’t use the database Keyword Arguments (kwarg) in connected_to. The database kwarg in connected_to is meant to be used for one-off scripts but is often used in requests, which is a dangerous practice because it re-establishes a connection every time. It’s deprecated in 6.1 and will be removed in 6.2 without replacement.

  • Red Hat and NVIDIA: Powering innovation at the edge

    Enterprises and telecommunication providers are looking at the edge as the newest IT footprint, observing the development of intelligent edge applications and monitoring the shift of workloads from traditional datacenters to the outer boundaries of public and private networks. The common realization is that bringing processing power and storage closer to the end user or data source is imperative to delivering high value services, scaling across geographically distributed locations and providing a faster, more satisfying service experience.

    Despite edge being somewhat of an opposite to the cloud from a datacenter point of view, it is much closer to "home" if you are operating outside of traditional enterprise boundaries. Yet in the context of the open hybrid cloud, the concept of edge computing is fully embraced. A large number of physical devices operating at the edge look somewhat like a cloud, especially since they have to work and be managed in unison, even if each one of them is performing its own set of tasks.

  • Red Hat and AWS extend collaboration: Introducing Amazon Red Hat OpenShift

    As we move deeper into the era of cloud computing, one thing remains clear: There’s no silver bullet for organization-wide digital transformation. We often see IT decision-makers seeking prescriptive guidance around the changing requirements of IT operations and application development in a containerized world. To better help these organizations address business-specific enterprise technology footprints and challenges, today we’re announcing an extension of the collaboration between Red Hat and AWS to deliver Amazon Red Hat OpenShift, a jointly-managed and jointly-supported enterprise Kubernetes service on AWS.

    Amazon Red Hat OpenShift will be a fully managed service that enables IT organizations to more quickly build and deploy applications in AWS on Red Hat’s powerful, enterprise Kubernetes platform, using the same tools and APIs. Developers will be able to build containerized applications that integrate natively with the more than 170+ integrated AWS cloud-native services to enhance agility, innovation and scalability. By blending Red Hat’s and AWS’ decades of enterprise IT knowledge and experience into Amazon Red Hat OpenShift, IT organizations will be able to launch cloud-native systems that can retain enterprise-grade security, be more agile and see improved performance while driving cost efficiencies.

    If you use or have been following NVIDIA GeForce Now, the cloud gaming platform that delivers PC titles you already own from sources such as Steam and Epic Games to a multitude of devices, the latest development seems to have emerged silently. Spotted by the team at GamingonLinux, users of Linux can now, it seems, access GeForce Now in either Chromium of Google Chrome. Indeed, previously this tactic involved fudging user agents to make GeForce Now believe you were on a Chromebook, following the launch of the web client for Google's laptops. And it works just fine, I logged in and played some games with no issues on Ubuntu in both browsers. And just to double check, Firefox still shows an incompatible device error.

Sculpt OS release 20.08

  • Sculpt OS release 20.08

    The new version of Sculpt OS is based on the latest Genode release 20.08. In particular, it incorporates the redesigned GUI stack to the benefit of quicker boot times, improved interactive responsiveness, and better pixel output quality. It also removes the last traces of the noux runtime. Fortunately, these massive under-the-hood changes do not disrupt the user-visible surface of Sculpt. Most users will feel right at home. Upon closer inspection, there are couple of new features to appreciate. The CPU-affinity of each component can now be restricted interactively by the user, components can be easily restarted via a click on a button, font-size changes have an immediate effect now, and the VESA driver (used when running Sculpt in a virtual machine) can dynamically change the screen resolution.

Sculpt OS 20.08 pulls in the notable Genode 20.08 changes like the redesigned GUI stack with better responsiveness and other benefits. It also includes the ability to run the Falk web browser as the first Chromium-based browser on Genode/Sculpt. Sculpt OS is Genode's effort around creating a general purpose OS but for right now is still largely limited to developers, hobbyists, and those wishing to tinker around with new operating systems.

    In this article, we will cover various methods to filter pandas dataframe in Python. Data Filtering is one of the most frequent data manipulation operation. It is similar to WHERE clause in SQL or you must have used filter in MS Excel for selecting specific rows based on some conditions. In terms of speed, python has an efficient way to perform filtering and aggregation. It has an excellent package called pandas for data wrangling tasks. Pandas has been built on top of numpy package which was written in C language which is a low level language. Hence data manipulation using pandas package is fast and smart way to handle big sized datasets.

  • Top GUI Frameworks that is every Python Developer's Favorite

    Python is one of the most popular and widely known programming languages that is a favorite in the developer community. Its advanced libraries and file extensions enable developers to build state-of-the-art tools for real-world problems, or simply design a GUI (Graphic User Interface). GUI plays an essential role in the computer world as it makes human-machine interaction easier. Python offers a diverse range of options for GUI frameworks. Some of these frameworks are more preferred by the developers to build both .apk and .exe applications. Moreover, its GUI toolkits include TK, GTK, QT, and wxWidgets, which come with more features than other platform-specific kits. Though the Python wiki on GUI programming lists on 30 cross-platform frameworks, we have selected our top 4 picks. They are: Kivy: It an open-source Python library for the rapid development of applications that makes use of innovative user interfaces, such as multi-touch apps. This liberal MIT-licensed Kivy is based on OpenGL ES 2 and includes native multi-touch for each platform. It is an event-driven framework based around the main loop, making it very suitable for game development. It supports multiple platforms, namely, Windows, MacOSX, Linux, Android-iOS, and Raspberry Pi. Unlike QtCreator, Kivy doesn’t have a visual layout program, but it uses its own design language to help you associate UI layout with code objects.
