What's the Difference between openSUSE and OpenMandriva

Filed under

Here's a comparison between openSUSE and OpenMandriva (continuing our comparison involving Mageia) the two European computer operating systems from our Free Libre Open Source Software community. The most obvious similarity from both is their name, which includes the word OPEN, which comes particularly from the Open Source Movement. In this article we will see several interesting stuffs from both around their architectures, distributions, control center, etc. so we know about their YaST and OMCC, respectively. If you want to know more similarities and differences of these two OSes, this article is for you. To make it easier to read, OS below is for openSUSE while OM is for OpenMandriva. Let's go!

openSUSE Tumbleweed – Review of Weeks 2021/13 & 14

Filed under

Dear Tumbleweed users and hackers,

Dominique has been enjoying a vacation these last two weeks and left Tumbleweed in my hands. Thanks to all who’ve helped out as I got to grips with holding the reins solo for the first time.

These two weeks also saw the long Easter weekend. That said, we still managed to release 5 snapshots (0325, 0329, 0330, 0401 and 0406) during this fortnight, with 0408 currently in testing and an 0409 likely to be checked in tonight.

Two Tumbleweed Snapshots Update Fetchmail, Mesa, More

Filed under

The two snapshots updated more than 30 packages and the latest snapshot, 20210406, gave rolling release users an update of Mozilla Firefox 87; the new release had several fixes including a fix to the video controls, which now have visible focus styling. The video and audio controls are now keyboard navigable. Firefox also sets a useful initial focus in the Add-ons Manager. New features in the browser release include the “Highlight All” feature on the “Find in Page”, which now displays tick marks alongside the scrollbar that correspond to the location of matches found on that page; this is a great feature for those who do keyword searches. Mozilla updates in the snapshot were finished as Thunderbird updated to version 78.9.0. The bugfix update for the email client had some security fixes and a fix for fields that were unreadable in the Dark theme in the General preferences panel. The update of fetchmail 6.4.18 fixed the configuration parser in fetchmailconf, which had an effect in version 6.4.16 when --sslcertfile was added to the configuration dump. The new version of fetchmailconf –version now prints the Python version in use. The snapshot gave users the 5.11.11 Linux Kernel, which had some changes for btrfs and x86 KVM. Other packages updated in the snapshot included spamassassin 3.4.5, git 2.31.1 and attr 2.5.1, which fixed a libtool library versioning regression.

SUSE/OpenSUSE Leftovers

  • Telegram Bridge - Zoltán's Blog

    I got lucky with my original hackweek project and I have managed to set up my Leap 15.3 based NAS and private cloud running on NextCloud earlier than planned.
    So I though that as an extra project I will set up a proper system monitoring service. The monit service is very handy (thanks for the idea to Paolo Stivanin) but by default it wants to send emails when something goes wrong. Instead of emails I would prefer a real instant message. I am using mostly Telegram for personal purposes. Sure I am using Signal, Matrix, Slack and Rocket.Chat too and technically I have WhatsApp account too. But I decided to start with Telegram.
    Installing and configuring monit was easy and quick. The monit is using so called alert where it can execute any shell command.

  • SUSE Sponsors 300 Scholarships in Cloud Native Education
  • Upgrading to the next PostgreSQL version

    We upgraded our internal PostgreSQL cluster to the latest version last week.

    Time passes by so quickly: we installed our PostgreSQL cluster around 2008. At least, this was the time of the first public MirrorBrain release 2.2, which was the reason to run a PostgreSQL installation for openSUSE. But MirrorBrain (and therefor the PostgreSQL cluster behind it) is way older. So maybe it’s fair to say that MirrorBrain started with openSUSE in 2005…?

    Anyway: if you maintain a database for such a long time, you don’t want to loose data. Downtimes are also not a good idea, but that’s why we have a cluster, right?

    While the MirrorBrain database is currently still the biggest one (>105GB in size and ~120 million entries alone in the table listing the files on the mirrors), our new services like Matrix, Mailman3, Gitlab, Pagure, lnt or Weblate are also not that small any more. All together use currently 142GB.

    We already upgraded our database multiple times now (starting with version 7. in the past). But this time, we decided to try a major jump from PostgreSQL 11 to 13, without any step in between.

YaST Packages, Nmap Get Updates in Tumbleweed

Filed under

Most of the package updates focused on libraries and YaST packages as well as documentation and nmap.

The snapshot from Tuesday, 20210330, updated an enormous amount of YaST translations and minor style adjustments and improvements were made with the yast2-theme 4.3.8 update. Extra validations were added to yast2-storage-ng 4.3.50 when creating a striped volume and when editing the physical volumes. The update to the 4.3.63 version of yast2-network brought about a dozen improvements to include adding support to write bridge and bonding configurations. Abstraction library libyui removed a dependency on Xlib and has a new packaging system in the update to 4.1.2. Network scanner nmap fixed a MySQL library that was not properly parsing responses in version 7.91 and the update of purple-lurch, which does secure multi-client end-to-end encryption, had some memory handling improvements in the 0.7.0 version update.

Topping the list of package updates for snapshot 20210329 was an update of setools 4.4.0 that added a configuration file driven analysis tool and Xfce file manager thunar 4.16.6 removed a dialog box and revamped documentation across components. A memory leak and an integer overflow fix was made in the update of checkpolicy 3.2. File system utility e2fsprogs 1.46.2 fixed warnings when resizing small file systems to a super-large ones. Spell checking library enchant 2.2.15 had some minor build system improvements and requires nuspell 4.1.0 or greater. Other packages that received updates were ffmpeg-4 4.3.2, perl-Net-HTTP 6.21, man-pages 5.11, rubygem-rspec-rails 5.0.1 and more.

Installing OpenSUSE Leap 15

Filed under

This is my experience on installing openSUSE, the green chameleon operating system, Leap Edition version 15.2 to my computer. It is a family of GNU/Linux hence a distant sibling to Ubuntu with a distinct feature called YaST, the green tapir control panel, on top of its RPM software package basis. I installed it on a virtual machine in normal method as I used on Ubuntu. However, this can be used for actual installation to the real hardware directly including in dualboot mode. Thus, I share this with you by wishing it to be useful. Let's go!

User Friendly Printer Management | openSUSE YaST

Filed under

At some point in my life with openSUSE, some default policy concerning printers changed that required me to enter the root credentials to resume a printer, should it be paused for whatever reason. I did not like this default and I was contacted about this annoyance, so, I set out to fix this and make life on the openSUSE desktop a generally better experience.

The Problem

When I have had a printer fail to start or get hung up for whatever reason, a manual restart of the printer would require authentication. This is fine for a user that is very Linux savoy but for a regular home user would likely be vapor locked when presented with this. I cold also argue it’s probably not a good idea for a typical user to need these credentials for this kind of trouble shooting.

  • Entire Rebuild of Tumbleweed Brings Enormous Update

    The most recent 20210317 snapshot updated more than a half dozen packages, which included the data plotting package kplotting as the lone KDE Frameworks 5.80.0 package to update in the snapshot. A memory leak fix was made in the update of flatpak 1.10.2 and a security update in the package fixed a potential attack where a flatpak application could use custom formatted .desktop files to gain access to files on the host system. An update of systemd 246.11 fixed a void pointer arithmetic warning and moved Secure Boot logic to a new file. Other updates in the snapshot included spacenavd 0.8, python-packaging 20.9, python-scipy 1.6.1 and rtkit 0.13.

    Snapshot 20210316 delivered most of the 5.80.0 Frameworks packages. Kirigami, which offers application framework components for mobile, had multiple improvements and fixes; it changed and improved the PlaceholderMessage for new Application Programming Interfaces. The Plasma Framework package ported a Plasma Style Kirigami Theme plugin to the new Kirigami API. A Flatpak manifest was also added to the Kirigami template. The snapshot brought an update of ImageMagick, which decodes HEIC images in sRGB instead of YCbCr. Mozilla Firefox 86.0.1 fixed a frequent Linux crash on the browser launch. The 5.11.6 Linux Kernel was updated in the snapshot, which had some Btrfs fixes. The kernel also enabled the headset microphone of the Acer Swift line. There was a fix for the maximum length of a password entered through a terminal with cryptsetup 2.3.5. Various fixes were made in the update of xfsprogs 5.11.0 and the Open Chinese Convert library opencc 1.1.2 added a Hong Kong Traditional Chinese conversion. A major version update of Python-hyperlink to 21.0.0 was included in the snapshot and bumped some long overdue dependencies. Other packages to update in the snapshot were gnutls 3.7.1, vim 8.2.2607 and sqlite3 3.35.0, which enhanced the .stats command to accept new arguments stmt and vmstep and causes the prepare statement statistics and only the virtual-machine step count to be shown, respectively.

  • openSUSE Tumbleweed – Review of the week 2021/11

    The biggest trouble of the week was the mirror infrastructure having a hard time catching up to the full rebuild. Tumbleweed itself was, as usual, solid and has been steadily rolling. In total, there were 4 snapshots (0312, 0315, 0316, and 0317) released last week.

  • New & Much Improved WireGuard Implementation Comes To FreeBSD - Phoronix

    Towards the end of last year FreeBSD imported a WireGuard kernel module. That initial WireGuard port to FreeBSD was sponsored by firewall company Netgate but the code quality was found to be poor and made without much involvement from upstream WireGuard developers. That FreeBSD WireGuard kernel code is now in the process of being replaced by a much better implementation.

    WireGuard lead developer Jason Donenfeld explained the situation today in an email, "Sometime ago, a popular firewall vendor tasked a developer with writing a WireGuard implementation for FreeBSD. They didn’t bother reaching out to the project...Then, at some point, whatever code laying around got merged into the FreeBSD tree and the developer tasked with writing it moved on."

  • Robert O'Callahan: Visualizing Control Flow In Pernosco

    In traditional debuggers, developers often single-step through the execution of a function to discover its control flow. One of Pernosco's main themes is avoiding single-stepping by visualizing state over time "all at once". Therefore, presenting control flow through a function "at a glance" is an important Pernosco feature and we've recently made significant improvements in this area. This is a surprisingly hard problem. Pernosco records control flow at the instruction level. Compiler-generated debuginfo maps instructions to source lines, but lacks other potentially useful information such as the static control flow graph. We think developers want to understand control flow in the context of their source code (so approaches taken by, e.g., reverse engineering tools are not optimal for Pernosco). However, mapping potentially complex control flow onto the simple top-to-bottom source code view is inherently lossy or confusing or both. For functions without loops there is a simple, obvious and good solution: highlight the lines executed, and let the user jump in time to that line's execution when clicked on. In the example below, we can see immediately where the function took an early exit.

  • Marco Castelluccio: On code coverage and regressions

    There are two schools of thought when it comes to code coverage: those who think it is a useless metric and those who think the opposite (OK, I’m a bit exaggerating, there are people in the middle…). I belong to the second “school”: I have always thought, intuitively, that patches without tests are more likely to cause postrelease regressions, and so having test coverage decreases risk. A few days ago, I set out to confirm this intuition, and I found this interesting study: Code Coverage and Postrelease Defects: A Large-Scale Study on Open Source Projects. The authors showed (on projects that are very different from Firefox, but still…) that there was no correlation between project coverage and the amount of bugs that are introduced in the project and, more importantly, there was no correlation between file coverage and the amount of bugs that are introduced in the file.

Nvidia GPU Passthrough To Windows VM From Linux Host

Nvidia has now officially enabled GPU passthrough support for Windows virtual machines on GeForce graphics cards. In other words, this effectively means it?s possible to run a Linux machine and then run a virtual Windows machine within it, and hand that unfettered access to a graphics card. This is a big win for those wanting to run Windows games from within a virtual machine on your Linux desktop. They will be able to play Windows-based games using a virtual machine with GPU passthrough enabled. Read more

  • A brief intro to Red Hat OpenShift for Node.js developers – IBM Developer

    Container-based deployment models are the modern way to develop and deliver your applications. The most common tool for building with containers is Kubernetes, an open-source container-orchestration system for automating computer application deployment, scaling, and management. Kubernetes has helped usher in a standardized way to deploy and manage applications at scale, but it can be a sprawling, difficult beast to manage when your application becomes more mature and more complex. A company will need to have a robust DevOps team to manage a full-fledged Kubernetes-based production system. [...] My colleague, JJ Asghar summed it up nicely: “OpenShift provides creature comforts to talk to the Kubernetes “API”—at the same level of robustness—as long as you’re willing to use the opinions OpenShift brings.” The good news? Those opinions are tried and tested, enterprise-ready choices with the backing and support of Red Hat. So, what do Node.js developers need to know about OpenShift deployment? This blog post covers the “what” and “how” of deploying your Node.js application in an OpenShift environment.

  • How Red Hat data scientists use and contribute to Open Data Hub

    Artificial intelligence (AI) and machine learning (ML) drive much of the world around us, from the apps on our phones to electric cars on the highway. Allowing such things to run as accurately as possible takes huge amounts of data to be collected and understood. At the helm of that critical information are data scientists. So, what’s a day on the job look like for data scientists at Red Hat? Don Chesworth, Principal Data Scientist, gives you a glimpse into his day-to-day in a short video (aptly named "A Day in the Life of a Red Hat Data Scientist") that’s now available on our website. Isabel Zimmerman, Data Science Intern, provides a look at some of the tools she uses on the job in "Using Open Data Hub as a Red Hat Data Scientist." We’ll cover some of the highlights in this post.
