A new OpenSUSE Linux is coming to town, and it's all about stability

Filed under
SUSE

Linux users come in many shapes and sizes, but those in the business world typically steer clear of the bleeding edge. That's why the OpenSUSE project recently switched to a two-pronged development approach, with one version focused on constant updates and another on enterprise-grade stability. On Wednesday, the latter took a big step forward.

The first beta version of OpenSUSE Leap 42.2 is now available, giving enterprises and other stability-minded users the chance to check it out and get a taste of what's coming in the final release, which is due Nov. 16. This is the first key update to the Leap software since OpenSUSE adopted its dual-path approach late last year with OpenSUSE 42.1.

“Leap is for pragmatic and conservative technology adopters,” Ludwig Nussel, the release manager for OpenSUSE Leap, said in the software's official announcement. “Testing the beta helps make Leap even more mature, so we encourage as many people as possible to test it.”

  • Getting Blockchain Technology Enterprise-Ready

    Blockchain technology first burst onto the scene as the underpinning of Bitcoin digital currency. Since then, open source distributed ledger technology has continued to evolve into an unparalleled asset tracker. It brings new efficiencies and much-needed transparency to online transactions in a world where assets move and change hands at Internet speeds.

  • An introduction to Linux network routing

    In June when I discussed basic network configuration, one thing I did not talk about then is routing. This article provides a very brief introduction to routing for Linux computers, designed for understanding simple environments.

    Every computer attached to a network requires some type of routing instructions for network TCP/IP packets when they leave the local host. This is usually very straightforward because most network environments are very simple and there are only two options for departing packets. All packets are sent either to a device on the local network or to some other, remote network.

After being in development for the past three months, the Salix 14.2 Xfce Edition operating system has finally hit the stable channels, and it is now available for download.

Based on the Slackware 14.2 GNU/Linux distribution and built around the lightweight and highly customizable Xfce 4.12 desktop environment, Salix 14.2 Xfce Edition ships with numerous improvements and new features that some of you who managed to test-drive the Beta and Release Candidate pre-releases are already accustomed with. Of course, many of the core components and default applications have been updated to their latest versions.

  • Emergency Service Window for Kolab Now

    We’re going to need to free up a hypervisor and put its load on other hypervisors, in order to pull out the one hypervisor and have some of its faulty hardware replaced — but there’s two problems;

    The hypervisor to free up has asserted required CPU capabilities most of the eligible targets do not have — this prevents a migration that does not involve a shut down, reconfiguration, and restart of the guest.

GNOME Control Center 3.22 to Update the Keyboard Settings, Improve Networking

Filed under
GNOME

The upcoming GNOME 3.22 desktop environment is still in the works, and a first Beta build was seeded to public beta testers last week, bringing multiple enhancements and new features to most of its core components and apps.

While GNOME 3.22 Beta was announced on August 22, it appears that the maintainers of certain core packages needed a little more time to work on various improvements and polish their applications before they were suitable for public testing. And this is the case of GNOME Control Center, which was recently updated to version 3.21.90, which means 3.22 Beta.

Security: Updates, Linux "Lockdown" Patches, Webmin FUD (Mischaracterisation) and Dawn for Security Vulnerabilities in HPC

  • Security updates for Tuesday

    Security updates have been issued by Debian (flask), openSUSE (clementine, dkgpg, libTMCG, openexr, and zstd), Oracle (kernel, mysql:8.0, redis:5, and subversion:1.10), SUSE (nodejs6, python-Django, and rubygem-rails-html-sanitizer), and Ubuntu (cups, docker, docker-credential-helpers, kconfig, kde4libs, libreoffice, nova, and openldap).

  • Linux "Lockdown" Patches Hit Their 40th Revision

    The long-running Linux "Lockdown" patches were sent out again overnight for their 40th time but it remains to be seen if these security-oriented patches will be pulled in for the upcoming Linux 5.4 cycle. The Linux Lockdown functionality is for restricting access to the kernel and underlying hardware by blocking writes to /dev/mem, restricting PCI BAR and CPU MSR access, disabling system hibernation support, limiting Tracefs, and restricting or outright disabling other functionality that could alter the hardware state or running Linux kernel image. Linux Lockdown has been opt-in only and designed for use-cases like honoring UEFI SecureBoot for ensuring nothing nefarious could happen once booted into the operating system by bad actors. Most end-users won't voluntarily want the lockdown mode due to all the restrictions in place, but could be a favor for enterprises and very security conscious users.

  • Backdoor Found in Webmin Utility [Ed: It is not a back door but a bug inserted by a malicious entity rather than the project developers themselves; this incident demonstrates or classically highlights the need for reproducible builds.]

    On August 17, the developer of the popular Webmin and Usermin Unix tools pushed out an update to fix a handful of security issues. Normally that wouldn’t generate an avalanche of interest, but in this case, one of those vulnerabilities was introduced intentionally by someone who was able to compromise the software build infrastructure used by the developers.

  • A New Dawn for Security Vulnerabilities in HPC

    In February 2018, Russian nuclear scientists at the Federal Nuclear Center were arrested for using their supercomputer resources to mine the crypto-currency, Bitcoin. Previously, high-performance computing (HPC) security breaches like this tended to be few and far between. However, recent trends are increasing the vulnerabilities and threats faced by HPC systems. Previously, compute clusters enjoyed a level of security through obscurity due to their idiosyncratic architectures in terms of both hardware, with different CPU architectures and networking, and software of often home-grown applications running on Unix-like operating systems. In addition, the reward for compromising a cluster wasn’t all that great. Although hacking into HPC data generated by atomic weapons research and pharmaceutical modelling does present a valuable outcome; meteorological institutes, astrophysics laboratories or other mathematical research is less so.

Lauterbach to support JTAG debug for RISC-V Linux

The Linux Kernel Awareness adaptation for the TRACE32 debugger is MMU aware. This allows symbols to be loaded for each process, kernel module or shared library in the target system and assigns them to the correct memory partition. This approach gives developers the ability to view and control all components of a target system from within the TRACE32 environment: kernel, kernel modules, device drivers, interrupt service routines, processes, threads and shared libraries. In addition to all standard JTAG features, some unique special extensions are provided, such as process aware breakpoints that can be set to trigger when a piece of shared code is executed by a particular thread or process, ability to read the kernel logs and to inspect the /proc and /sys filesystems and all mountpoints. The system is also fully SMP aware and supports multi-core designs where the kernel is able to schedule processes dynamically across a number of processor cores, providing users with complete system visibility in a system which is self-managing according to real-world demands.

Raspberry Pi gets MIT's Scratch 3 programming language for Raspbian

Ever since Scratch 3 was released this January, a team at the Raspberry Pi Foundation has been working with MIT to develop an offline, installable version for the Raspberry Pi. That offline version is now available, offering students and beginners an easy environment to begin coding with the language's visual 'code blocks', as well as paint and sound-editing tools. Scratch 3 requires installing the latest version of Raspbian known as 'Buster', the latest version of Debian Linux that was released alongside the Raspberry Pi 4 in June. Due to the memory requirements of Scratch 3, the Raspberry Pi Foundation is recommending it is installed on a Raspberry Pi 4 with at least 2GB of RAM. The 2GB model costs $45.
