Overcoming the Challenges of Embracing Linux: a Different Perspective

Filed under
SUSE

After months of working at SUSE, my Jungle Green t-shirt was finally recognized at a store. “SUSE?” the gentleman asked, pointing at the large white letters.
“Yes, I work there!” I responded, thrilled that I had the opportunity to engage in our mutual love of the chameleon, Geeko, “But I don’t work on the technology, I’m in Program Management.”
“Well, let me ask you this – what is the operating system on your computer at home?” he asked, inquiring to my level of SUSE-ness.
“Just the basic… Microsoft,” I responded.
He continued, “I have a virtual machine with Slackware 1.0 I’m running, and I’ve been trying to get my hands on something old, openSUSE older than 5.3.”
I breathed a sigh of relief when our conversation was cut short and he ran off to help another customer. Slackware? Virtual Machine? All terms I had just enough exposure to know what category they belonged in, yet not enough to carry a conversation. Despite the embarrassment, I knew I wasn’t alone. A 2020 study by the AnitaB.org Institute found that women make up 28.8% of the tech workforce. When considering open source technology, this number further shrinks down to the single digits.
Nonetheless, the number of women becoming cloud native practitioners is growing. Recently, Lynne Chamberlain, CEO of SUSE Rancher Government Solutions, and Denise Schannon, Director of Engineering, joined special host Katie Gamanji for a special feature of OCTOpod in which they discussed their contributions to Linux, challenges they have faced and shared inspiring stories on how they’ve overcome those challenges to get to where they are today.

Thunar, Firefox, Python Update in Tumbleweed

Filed under
SUSE

Five Tumbleweed snapshots became available to users of openSUSE’s rolling release this week.

A couple smaller- and medium-sized snapshots brought new software updates for Xfce’s Thunar, the Linux Kernel, Mozilla Firefox, PostgreSQL, Python and more.

The 20210915 snapshot had two package updates. There was an update of translations for the manpages-l10n package to version 4.11.0, which enabled Hungarian translations. The tool set package for accessing and modifying virtual machine images, libguestfs 1.44.2, had a large amount of changes; it added and removed several patches and relicensed setup.py to LGPLv2+ from its original GPLv2+ license.

Xfce’s Thunar package was updated in snapshot 20210914; the update to the file manager 4.16.9 version fixed a memory leak, updated translations and disabled automatic queueing of file transfers. Linux Kernel 5.14.2 had a few USB serial control fixes and a Common Vulnerabilities and Exposures fix; the fix for CVE-2021-3640 could allow a privileged local user to crash the system or escalate their privileges on a system. The package for video and image frames, pfstools, updated to version 2.2.0 and provided many fixes allowing the package to work with newer versions of libraries. Also updated in the snapshot were aria2 1.36.0 and text browser links 2.24.

SUSE

There was one openSUSE Tumbleweed snapshot this week out of five that brought an enormous amount of package updates for those using the rolling release.

Snapshot 20210904 brought updates for systemd, GTK4, Mesa, KDE’s Plasma and Gear and many other packages.

The most recent snapshot to be released was 20210908; it updated fuse3 3.10.5 and made various improvements to unit tests more robust for the Filesystem in Userspace package. The mpg123 1.29.0 update added an--enable-runtime-tables. An update of yast2 4.4.17 provided some maintenance for the systemd package that arrived earlier in the week. A few other packages like glslang 11.6.0, libstorage-ng 4.4.36 and pinentry 1.2.0 were also updated in the snapshot.

Snapshot 20210907 updated seven packages. The package manager zypper 1.14.49 made a change to avoid calling su as it can be too restrictive for sudo user umask. The package manager library libzypp also had an update to version 17.28.3, which had a policy modification for avoid the breaking of a single rpm transaction. The AV1 decoder package dav1d 0.9.2 had some Streaming SIMD Extensions 3 and SSE4 optimizations for x86_64. Other packages updated in the snapshot were geoclue2 2.5.7, mozilla-nss 3.69.1, supermin 5.2.1 and an update to plymouth.

Filed under
SUSE

Snapshot releases of openSUSE’s rolling release Tumbleweed have been constantly trickling out to users since last week’s review.

This review will cover the five snapshots made available since August 26. Each of the snapshots delivered about a handful of updated software packages.

Snapshot 20210831 updated bind to version 9.16.20, which fixed a Common Vulnerability and Exposure; CVE-2021-25218 an assertion failure could have allowed an attacker to abused the Path Maximum Transmission Unit Discovery protocol to trick bind into exceeding the interface MTU. The C Library for manipulating module metadata files libmodulemd updated to 2.13.0 and the modulemd-validator enables a user to constrain a document type with a new --type option. The other packages to update in the snapshot were libqmi 1.28.8 and libjpeg-turbo 2.1.1, which fixed a couple regressions affecting AArch64 and arm 32-bit hardware.

Linux Kernel 5.13.13 was one of the two packages updated in the 20210830 snapshot. The Direct Rendering Manager had some fixes in the kernel update and added an AAL output size configuration. The kernel update also had an Advanced Linux Sound Architecture enablement for the 4-speaker output in the Dell XPS 15 9510 laptop. The other package to update in the snapshot was perl-Image-ExifTool, which had a version bump to 12.30.

Top 11 Reasons YaST makes openSUSE Awesome

Filed under
SUSE

I read a lot of negativity about YaST on the webs, Reddit, YouTubes… other places… and I wanted to write a counter to all those negative statements. Why? YaST was the biggest selling point for me to go openSUSE when I departed the Mandrake / Mandriva world about 10 years ago (at the time of writing). I use YaST regularly and have grown to truly enjoy the tools for system administration. I am not good at remembering the various commands in the terminal to do a thing even though I do take a number of notes. YaST is just so quick to get to a solution, especially when there are lots of little steps involved. I originally was going to make it 8 reasons, then 10 but after getting to 16, I decided I had to pare it down and will probably have to do follow up blatherings on the various modules. Here are my reasons why YaST makes openSUSE Awesome.

Consolidated Control Center of Tools

This is my primary love for YaST. I know I can go to one place and get to any system level function for my computer. I have this general requirement that I want all my tools in one spot, I do not want to have to hunt for the proper tool to accomplish a specified task, with YaST, I get that and managing my openSUSE machines is super convenient. I don’t have to remember any esoteric commands in the terminal, as much as I love the terminal and the power it provides. I often cannot remember the commands to fix or alter a thing. This is especially true with functions I do not perform regularly.

openSUSE set the standard for me with YaST, for me to consider any Linux distribution, I must have a “Control Center” for all my system management tools. Basically, at this point, I am spoiled and although I can get along fine with other distributions, I never feel fully comfortable with a system that doesn’t have this luxury item.

GNA and Beast Canyon NUC11 compatibility with openSUSE

Filed under
Hardware
SUSE

While focused on the openSUSE Innovator initiative as an openSUSE member and official Intel oneAPI innovator, I tested the Beast Canyon NUC 11 machine on openSUSE Leap 15.3 and Tumbleweed. With all the work, we made available in the SDB an article on how to use the GNA Technologie on the openSUSE platform. More information can be found at https://en.opensuse.org/SDB:Install_GNA_in_NUC_Beast_Canyon.

Beast Canyon (still on pre-order) is the highest-performing Intel® NUC available today. Beast Canyon is the evolution of Intel’s modular gaming mini PC, a more compact gaming PC than most gamers could dream of building on their own. The equipment in some models has the Core i9-11900KB processor with the GNA feature: Gaussian & Neural Accelerator Library.

Tumbleweed Updates Kismet, PulseAudio, Python

Filed under
SUSE

The latest 20210824 snapshot updated Mozilla Thunderbird from version 78.13.0 to version 91.0.1, which is the next Extended Support Release codebase. The new email client offers many new features like keyboard shortcuts to access To/CC/BCC fields and a PDF JavaScript viewer is now included in Thunderbird. Two major version updates were in the snapshot; an update to nftables 1.0.0 now recognizes the command-line option --define. GTK based volume control tool pavucontrol 5.0 has support for switching Bluetooth codecs that comes new in PulseAudio 15.0, which was released in the 20210823 snapshot 24-hours earlier. GNU Compiler Collection was updated to version 11.2 and fixed the One-time Passwords In Everything package with glibc 2.34. A few GNOME and RubyGems packages were updated in the snapshot. Command-line utility grep updated to version 3.7, which skipped the stack overflow tests in the qemu build. The runtime nodejs16 16.6.2 update fixed the improper handling of untypical characters in domain names and fixed three Common Vulnerabilities and Exposures.

The network-detector, packet-sniffer, and intrusion-detection package Kismet updated to its latest 2021.08 version in snapshot 20210823; the packages made some small improvements and has a new Wireless Intrusion Detection System alert. PulseAudio 15.0 dropped several BlueTooth patches and improved hardware support. PDF rendering package poppler 21.08.0 added an Application Programming Interfaces to allow the addition and modification of outlines into a PDF. An updated 1.9.7 version of sudo enabled OpenSSL support for a secure central session recording collection. And yast2-bootloader 4.4.6 replaced mkinitrd with dracut.

Microsoft Exchange Autodiscover protocol found leaking hundreds of thousands of credentials

A flaw in Microsoft's Autodiscover protocol, used to configure Exchange clients like Outlook, can cause user credentials to leak to miscreants in certain circumstances. The upshot is that your Exchange-connected email client may give away your username and password to a stranger, if the flaw is successfully exploited. In a report scheduled to be published on Wednesday, security firm Guardicore said it has identified a design blunder that leaks web requests to Autodiscover domains that are outside the user's domain but within the same top-level domain (TLD). Exchange's Autodiscover protocol, specifically the version based on POX XML, provides a way for client applications to obtain the configuration data necessary to communicate with the Exchange server. It gets invoked, for example, when adding a new Exchange account to Outlook. After a user supplies a name, email address, and password, Outlook tries to use Autodiscover to set up the client.

  • Location history: How your location is tracked and how you can limit sharing it

    In real estate, the age old mantra is “location, location, location,” meaning that location drives value. That’s true even when it comes to data collection in the online world, too — your location history is valuable, authentic information. In all likelihood, you’re leaving a breadcrumb trail of location data every day, but there are a few things you can do to clean that up and keep more of your goings-on to yourself. [...] For some apps, location helps them function better, like navigating with a GPS or following a map. Location history can also be useful for retracing your steps to past places, like finding your way back to that tiny shop in Florence where you picked up beautiful stationery two years ago. On the other hand, marketing companies use location data for marketing and advertising purposes. They can also use location to conduct “geomarketing,” which is targeting you with promotions based on where you are. Near a certain restaurant while you’re out doing errands at midday? You might see an ad for it on your phone just as you’re thinking about lunch. Location can also be used to grant or deny access to certain content. In some parts of the world, content on the internet is “geo-blocked” or geographically-restricted based on your IP address, which is kind of like a mailing address, associated with your online activity. Geo-blocking can happen due to things like copyright restrictions, limited licensing rights or even government control.

  • An update on Memory Safety in Chrome [LWN.net]

    The Google security blog provides an overview of what is being done to address memory-safety problems in the Chrome browser.

  • Chrome 94 Released for Android, macOS, Windows, Linux: What's New | Technology News

    Chrome 94 stable update has been released by Google for Android, iOS, Mac, and Windows operating systems. The update will be rolled out over the coming weeks and it brings new security features, new functionality, and bug fixes. Google Chrome 94 stable is the first version of Chrome of the new four-week release cycle. Previously, Chrome update was released every six weeks. Its features include HTTPS-First mode that makes users browsing more secure. Also, Google said that 19 different security issues were fixed in the Chrome 94 version. The update for Google Chrome was announced through a blog post on September 21. Chrome 94 introduces HTTPS-First mode. It is available in Chrome for desktop systems and for Android. HTTPS is a more secure version of HTTP and many websites support it. With the latest update, the browser will also show a full-page warning when the user loads a site that doesn't support HTTPS. This ensures privacy when using public Wi-Fi. Google says this was previously planned for Chrome 92.

  • Google emits Chrome 94 with 'Idle Detection' API to detect user inactivity amid opposition

    Google has released Chrome 94 for desktop and Android, complete with an "Idle Detection" API to detect user inactivity, despite privacy concerns expressed by Mozilla and Apple. New and changed features in Chrome 94 are listed here and include the removal of the AppCache feature, described as a "security and stability liability", and something which has "imposed a tax on all of Chrome's significant architectural efforts." There is also a new VirtualKeyboard API with more control over its shape and an event fired when it covers page content; more efficient low-level access to media encoders and decoders; and a new JavaScript Self Profiling API which enables developers to collect JavaScript performance profiles from end users.

Kernel: Google, Xen, and Mesa

  • Google Finally Shifting To "Upstream First" Linux Kernel Approach For Android Features

    Google's Android had been notorious for all of its downstream patches carried by the mobile operating system as well as various vendor/device kernel trees while in recent years more of that code has been upstreamed. Google has also been shifting to the Android Generic Kernel Image (GKI) as the basis for all their product kernels to further reduce the fragmentation. Looking ahead, Google is now talking of an "upstream first" approach for pushing new kernel features. Google's Todd Kjos talked today during Linux Plumbers Conference (LPC2021) around their Generic Kernel Image initiative. With Android 12 and their Linux 5.10 based GKI image they have further cut down the fragmentation to the extent that it's "nearly eliminated". With the Android 12 GKI, most of the vendor/OEM kernel features have now either been upstreamed into the Linux kernel, isolated to vendor modules/hooks, or merged into the Android Common Kernel.

  • Clang-format for Xen Coding Style Checking Scheduled - Xen Project

    At the moment there is no tool that would allow to format patches in Xen. The idea of Xen-checker is to use the clang-format approach as a base for Xen ‘checkpatch’ process. The new tool consists of modified .clang-format configuration file to automate Xen patches format checking and reformatting. The tool can be used as a pre-commit hook to check and format every patch automatically. Some features are missing in the clang configurator, so new clang-format options have been proposed for more flexible code formatting. Also, the purpose of the topic is to start the discussion about the existing rules for Xen code formatting to eliminate possible inaccuracies in the work of the Xen checker. This will make it easier to adhere to the unanimous decision.

  • Mesa Merge Pending For Vulkan Ray-Tracing On Older AMD GPUs - Phoronix

    Merged yesterday for Mesa 21.3 was open-source Vulkan ray-tracing for AMD RDNA2 / RX 6000 series GPUs with the RADV driver. Opened today now is a merge request that would provide Vulkan ray-tracing with RADV to pre-RDNA2 GPUs on this driver going back to the likes of Polaris, granted the performance is another story. Joshua Ashton known for his work on DXVK and other Direct3D-on-Vulkan efforts for Valve has opened the merge request to enable RADV Vulkan ray-tracing for older generations of AMD GPUs.

Astro Pi Mk II, the New Raspberry Pi Hardware Headed to the Space Station

While Izzy and Ed are still going strong, the ESA has decided it’s about time these veteran Raspberries finally get the retirement they’re due. Set to make the journey to the ISS in December aboard a SpaceX Cargo Dragon, the new Astro Pi MK II hardware looks quite similar to the original 2015 version at first glance. But a peek inside its 6063-grade aluminium flight case reveals plenty of new and improved gear, including a Raspberry Pi 4 Model B with 8 GB RAM. The beefier hardware will no doubt be appreciated by students looking to push the envelope. While the majority of Python programs submitted to the Astro Pi program did little more than poll the current reading from the unit’s temperature or humidity sensors and scroll messages for the astronauts on the Astro Pi’s LED matrix, some of the more advanced projects were aimed at performing legitimate space research. From using the onboard camera to image the Earth and make weather predictions to attempting to map the planet’s magnetic field, code submitted from teams of older students will certainly benefit from the improved computational performance and expanded RAM of the newest Pi. As with the original Astro Pi, the ESA and the Raspberry Pi Foundation have shared plenty of technical details about these space-rated Linux boxes. After all, students are expected to develop and test their code on essentially the same hardware down here on Earth before it gets beamed up to the orbiting computers. So let’s take a quick look at the new hardware inside Astro Pi MK II, and what sort of research it should enable for students in 2022 and beyond. Read more
