It’s time once again for The Weekender. This is our bi-weekly departure into the world of amateur radio contests, open source conventions, special events, listener challenges, hedonism and just plain fun. Thanks for listening and, if you happen to get a chance, feel free to call us or e-mail and send us some feedback. Tell us how we’re doing. We’d love to hear from you.
We discuss Chris’s latest wall-mounted tablet solution for Home Assistant and several scripts to pimp your Plex setup.
VMware has found the Linux 5.13 kernel that was released as stable one month ago has led to a serious performance regression for their ESXi enterprise hypervisor.
VMware found that there is a big performance regression with Linux 5.13 under their ESXi software. They found that ESXi compute workloads could be affected by up to 3x while networking workloads were at only a 40% regression. Their compute tasks were as simple as Linux kernel compile times that were severely impacted.
VMware engineers found that this very significant performance regression came from a scheduler change… While the patch in question “sched: Move SCHED_DEBUG sysctl to debugfs” sounds rather mundane, it was found to ultimately impact the default value of sched_wakeup_granularity_ns.
AMD driver engineers have submitted their latest batch of AMDGPU feature updates to DRM-Next for queuing ahead of the Linux 5.15 merge window opening up in about one month’s time. With this latest pull request the big addition is the new “Cyan Skillfish” GPU support.
Posted earlier this month were Linux graphics driver patches for “Cyan Skillfish”, which is the Navi 1x graphics in an APU form factor. Yes, forthcoming Navi 1x APU/SoC rather than Navi 2x or the many Vega-based APUs out there. Details on what “Cyan Skillfish” ultimately maps to remains to be confirmed beyond being an RDNA(1) part.
Years ago particularly when the open-source Linux GPU drivers were in their infancy it was known in some cases having to fake/spoof the GPU driver name or model in order to workaround artificial bugs / problematic code paths targeted to a particular OpenGL driver or even to achieve greater performance. With a new Mesa merge request called “Unleash the dragon!”, this is still very much a problem in 2021 even now in the Android space.
Google’s Rob Clark who founded the Freedreno project for open-source Qualcomm Adreno project years ago created this new “Unleash the dragon!” merge request for Mesa. In 2021 the problem has shifted to Android games still relying on OpenGL have become accustomed to artificially changing their settings/capabilities based on the OpenGL renderer and GPU model.
I don’t feel like blogging about zink today, so here’s more about everyone’s favorite software implementation of Vulkan.
It’s been one year since the last xf86-video-amdgpu release in the form of v19.1 and about two years since the release before that with v19.0… Now the xf86-video-amdgpu 21.0 driver is ready for those who need it. As with all open-source Linux graphics drivers, these X.Org DDX releases are of little value these days given the migration to Wayland and those sticking to X.Org most often just using the generic xf86-video-modesetting driver. All the interesting open-source graphics magic these days happen within the DRM/KMS kernel driver components and Mesa. But unlike Intel who hasn’t even issued a new xf86-video-intel development release in six years or going back seven years to the last stable release, AMD does still put out the yearly or so DDX update.

PipeWire, all the rage these days, was originally developed for video but was later enhanced to support audio as well, and is now an alternative to PulseAudio and JACK. My laptop running Gentoo Stable (amd64) with the KDE Plasma Desktop had been working fine with PipeWire for some time. The pulseaudio and screencast USE flags were both declared in the file /etc/portage/make.conf. Both audio playback and recording worked fine until a recent upgrade of the packages in my world file, when neither worked any more. The Audio Volume loudspeaker icon (the applet kde-plasma/plasma-pa) on the KDE Plasma panel had a red line through it, and the KMix loudspeaker icon (the applet kde-apps/kmix) on the panel was greyed out. Although I cannot be sure, I suspect the problem started when the first version of PipeWire that supported audio was released. The output of the command ‘ps -ef | grep pulse‘ showed me that both PulseAudio and PipeWire were running. At the time I did not know that PulseAudio is not supposed to be running at the same time as PipeWire. Sometimes when I booted the laptop and logged in, the loudspeaker icons on the Panel would appear correctly and audio output would work properly, but usually this was not the case. This behaviour made me wonder if there was some sort of race condition between the two applications at startup.
SonarQube is an open-source program to analyze the code quality, formerly it was known as Sonar. Here we will let you know the commands and steps to install SonarQube on Ubuntu 20.04/18.04 LTs server

In this tutorial, we will show you how to create an SSH Tunnel using Putty and Firefox. SSH tunnel is an encrypted tunnel created through an SSH protocol. SSH Tunnel will be used to transfer unencrypted data over a network through an encrypted channel. If your service provider or some organization has blocked certain sites using their proxy filter you can bypass them with a SOCKS 5 proxy tunnel. In general, SOCKS is a protocol that establishes a TCP connection and exchanges network packets between a client and a server through a proxy server. If you can connect to an external SSH server, you can create an SSH tunnel to forward a port on your local machine to a port in the other machine which will be the other end of the tunnel.

I will show you the step-by-step installation of the Foreman on Ubuntu 20.04 (Focal Fossa). You can follow the same instructions for Ubuntu 18.04, 16.04, and any other Debian-based distribution like Linux Mint.
Some time ago I’ve replaced Google Analytics with Plausible. It works great, except for one tiny thing. The map of visitors was empty. Due to various layers of Network Adress Translations in k3s networking setup, the original client IP address information was not reaching analytics engine.
There are solutions – there is a PROXY Protocol exactly for that case. And Traefik, which handles ingress in k3s, supports PROXY. Only a bit of gymnastic was needed.
Legacy IPv4 traffic entry point to my bare-metal cluster has a form of a small in-the-cloud virtual machine. It routes incoming TCP/443 traffic over the VPN into the cluster. The VM itself is not a part of kubernetes setup – I cannot run any pods on it. I’ve decided to use Ansible to configure it.

Wine developers have popped open a new bi-weekly development snapshot of this software that allows Windows games/applications to run on Linux and macOS along with being what powers Valve’s Steam Play (Proton) and CodeWeavers’ CrossOver.
Wine 6.14 is this latest development snapshot for enjoying Windows applications and game support under Linux. With Wine 6.14 their integrated Mono engine is updated against Mono 6.3, more 32-bit to 64-bit thunks have been implemented in the WOW64 DLL, there is continued preparations around GDI system call support, and various bug fixes.
The Wine hackers have today popped open another bottle to let it breathe for a bit, with the development build Wine 6.14 now available for testing.
For newer readers and Linux users here’s a refresher – Wine is a compatibility layer built for operating systems like Linux, macOS and BSD. The idea is to allow other platforms to run games and applications only built and supported for Windows. It’s also part of what makes up Steam Play Proton. Once a year or so, a new stable release is made.
Valve released a Steam Client Beta update that introduces a Storage Manager, updated the Downloads page, and made other improvements that seem intended to prepare the platform for the release of the new Steam Deck handheld gaming device later this year.
The new Storage Manager is supposed to allow Steam users to “better manage various game content installed on your drives,” as Valve puts it, by making it easier to see what exactly is installed on each drive. That could prove vital for the Steam Deck, which ships with 64GB, 256GB, or 512GB of onboard storage that can be supplemented by a microSD card.
Valve also made significant changes to the Downloads page. In addition to user interface tweaks meant to highlight the game that’s currently being downloaded, the new page adds drag-and-drop support for reordering the update queue, changes the Latest News button to a Patch Notes button, and makes it easier to view the contents of an update, among other things.
Valve stole Nintendo’s thunder – people were already lukewarm on the minimal upgrades brought on by the Switch OLED, but then Valve’s own portable console arrived to offer people an alluring alternative.
Many complain about the lack of physical game media, which makes it easier to sell old games you no longer need. And that’s true, but Steam’s whole reason for being is to make buying, installing and playing a new game just a few clicks away and doing it online makes the whole process frictionless
The Steam Deck is an exciting device for numerous reasons, and we will keep giving you updates as we keep learning about some additional details as they come. In the past week, several additional details have surfaced…
Publisher Walkabout is having a bit of sale over on GOG.com and you can grab yourself a free copy of the travelling adventure Wanderlust: Transsiberian.
There was much excitement for Linux gamers with today’s release of a new Steam beta that brought several Linux-specific updates among a range of cross-platform improvements, most hopefully aimed at optimizing the gaming client before the launch of the Steam Deck.
Among the updated packages that landed this week in the rolling release were curl, GNU Compiler Collection, Node.js, redis and LibreOffice.
The office suite package LibreOffice came in snapshot 20210728. The update to version 7.1.5.2 provided bugfixes addressing some regressions and a few fixes were made to prevent crashes in Writer. Linux Kernel firmware was updated in the snapshot and PDF rendering library poppler 21.07.0 provided some minor code improvements for build systems while also fixing a memory leak on broken files. The 2.32.3 webkit2gtk3 fixed several crashes and rendering issues and addressed a dozen Common Vulnerabilities and Exposures.
The 20210727 snapshot provided just a single package update to gcc11. The update of the head branch included the 11.2 release candidate and a corrected adjustment to the General Public License version 3.0. The package update also provided a libc-bootstrap cross compiler for AArch64 and RISC-V.
Dear Tumbleweed users and hackers,
Solid and predictable – that’s what openSUSE Tumbleweed tries to offer to the users. This also shows in the number of snapshots we release. 5 – 7 snapshots a week is absolutely normal – and was also achieved this week, in which we have published 6 snapshots (0723, 0724, 0725, 0726, 0727, and 0728).
Here’s your weekly Fedora report. Read what happened this week and what’s coming up. Your contributions are welcome (see the end of the post)!
CodeFlare is all about end-to-end workflows and pipelines and aims to drastically reduce the time it takes to set up, run, and scale machine-learning tests. The motivation behind CodeFlare, according to Priya Nagpurkar, Director of Cloud Platform Research at IBM Research, “was the emergence of these converged workflows. So you have AI, machine learning, big data, and even simulations and modeling, all coming together into tightly integrated workflows.” But how does this differ from traditional AI/ML platforms? According to Nagpurkar, the difference is, “When I can think about my logic, and I have higher-level interfaces, and I don’t have to worry about the runtime aspects, how do I scale? How do I map it to massive infrastructure?” In the end, CodeFlare deals with workflows as a whole, instead of individual elements.
“The last 15 years have been tough times for many Americans, but there are now encouraging signs of a turnaround,” wrote economists Erik Brynjolfsson and Georgios Petropoulos in The Coming Productivity Boom, a recent opinion article in the MIT Technology Review. “Productivity growth, a key driver for higher living standards, averaged only 1.3% since 2006, less than half the rate of the previous decade. But on June 3, the US Bureau of Labor Statistics reported that US labour productivity increased by 5.4% in the first quarter of 2021. What’s better, there’s reason to believe that this is not just a blip, but rather a harbinger of better times ahead: a productivity surge that will match or surpass the boom times of the 1990s.”
After growing at an average annual rate of around 2.8% between 1947 and 1973, US productivity has significantly slowed down, except for the Internet-driven productivity boost between 1996 and 2004. Despite the relentless advances of digital technologies over the past 15 years, – from smartphones and broadband wireless to cloud computing and machine learning, – productivity has only grown at an anemic 1.3%, between 2006 and 2019. Most OECD countries have seen similar slowdowns.
What accounts for this puzzling so-called productivity paradox and when might it finally end? Over the past several years, Brynjolfsson and his various collaborators have explored this question, first at MIT where he was faculty director of the Initiative on the Digital Economy, and since 2020 at Stanford, where he’s Director of the Stanford Digital Economy Lab. Brynjolfsson discussed alternative explanations for the paradox at a recent MIT conference.
In 2019, the Red Hat User Experience (UX) team set out to create our Red Hat digital design system. It has evolved from a few research decks and Adobe XD files to a comprehensive shared design kit library and documentation website that many internal and external teams use every day.
Our mandate was to design flexible building blocks and use new web technologies to create consistent user experiences that instill trust among visitors or customers who use our system of websites and apps. In this post, we’ll share some of our challenges, actions and outcomes.
This is my fifth month of working for LTS. I was assigned 12 hrs and worked all of them.
Customers purchase the SoCs from the SynchroKnot-authorized manufacturer directly, stack them up with spacers and pillars, and install SynchroKnot vSoC on the supported Debian or Debian-variant of the Linux operating system.
Xubuntu users can look forward to some new default apps later this year.
A handful of additional desktop applications are set to ship in Xubuntu 21.10 when it’s released later this year.
“Recent team votes have expanded Xubuntu’s collection of apps’”, writes Xubuntu developer Sean Davis in a blog post detailing work going into the upcoming release.
The applications set to be added include disk usage analyser app Baobab (pictured above, image credit Sean Davis) and the GNOME Disk Utility. Both of these are handy tools to have around. The former is incredibly useful for hunting down disk-space hogging files and folders, while the latter is my (and many others’) go-to partition manager.
Constructing and racing a pinewood derby car is a great way to introduce young children to the world of engineering and mathematics. Many competitions will limit how heavy a car can be to avoid unfair advantages when it comes to momentum, meaning that contestants will try to add as much weight as possible. However, the center of gravity is also important since having it too far forward or backward can affect the acceleration or traction of the car. To address this problem, willemvl on Instructables created a small DIY scale that measures exactly where this center lands on the car to assist in balancing.
We all know as makers that trying to cut those little wires to the perfect length can be one of the most tedious and frustrating aspects of soldering together a project. Whether it is because the wire cutters slipped or the lengths of the conductors are all different, the lack of consistency is detrimental. This is why the maker and YouTuber known as Mr Innovative has created an automated multi-colored wire cutting machine that is able to achieve the precise wire length every single time.
Templates are here for the Oplà IoT Kit. This is a new feature that takes you from unboxing your kit to uploading a sketch and getting a project up and running in record time. And you can do the whole thing without needing any coding.

SiFive announced a 11 percent faster “21G2” release of its Essential 7-series cores, including the Linux-ready U74. In other RISC-V news, Canaan is launching a dual-core, 3-TOPs Kendryte K510 CPU that is debuting on a quadruped robot.
SiFive has announced a 21G2 update to its RISC-V architecture Essential 7-series. We also take a look at the new RISC-V-based Kendryte K510 CPU, which will debut on a dog-like XGO-Mini Pro robot (see farther below).
Kendryte K510 RISC-V AI processor is the successor of Kendryte K210 with much more AI processing power (2.5/3 TOPS) that makes it suitable for robotics projects demanding much lower latency and quasi-real-time inference.
One of the first products to make use of Kendryte K510 capabilities is Luwu Intelligence Technology’s XGO Mini Pro, a four-legged robot that looks like a dog with a tiny head providing the “smarts” for the system including face detection, image recognition, object tracking, voice recognition, and so on.
I’ve been using the web browser qutebrowser for several years now. It has been my favorite web browser since the very first day when tried it. I like the minimal user interface and I love that it’s 100% keyboard driven.
Unfortunately, after more than 5 years with qutebrowser, I’m back with Firefox. I don’t know if it’s temporary or not. The reason for it is primarily due to the elephant in the room; QtWebEngine.
Unless otherwise noted, changes described below apply to the newest Chrome beta channel release for Android, Android WebView, Chrome OS, Linux, macOS, and Windows. Learn more about the features listed here through the provided links or from the list on ChromeStatus.com. Chrome 93 is beta as of July 29, 2021.
Following last week’s release of Chrome 92, Google has now made available the Chrome 93 beta as the next iteration of their cross-platform web browser.
Arguably most interesting with Chrome 93 beta is the Multi-Screen Window Placement API. This new API makes it easier to manage several displays and can be used for use-cases like presentations where one display may be showing a slide deck while another display is showing the speaker notes, managing multiple windows for tool panes like for image and video editors, or virtual trading desks with showing multiple related windows. With Chrome 93 this new Multi-Screen window Placement API is exposed as an origin trial.
With more work and education happening online (and at home) you may find yourself needing new ways to juice your productivity. From time management to organizational tools and more, the right browser extension can give you an edge in the art of efficiency.
The steering committee of the GNU C Library (glibc) has decided that contributors no longer have to automatically transfer their copyrights to the Free Software Foundation (FSF). The changes for glibc will take effect on August 2, 2021 and will be effective for all ongoing development branches of the Library project. From this point onwards, everyone who contributes code to the glibc project is free to decide whether they want to apply their patches with or without transferring rights to the FSF.
Auditing open source software license terms is easier said than done. Like any well-managed process, ongoing compliance is the best practice. This article briefly expands on earlier provided practical open source software compliance tips (see OSS an IP Perspective and Why Security Matters Even More for On-premise Software Vendors | The Privacy Hacker).
he layout is fairly intuitive. The upper half of the board is controlled by player 1, and the lower half of the board is controlled by player2.
I also worked on the basic working of the game. I am currently detecting mouse clicks on any of the valid pits on each player’s turn, and moving the corresponding seeds to adjacent pits. If the number of seeds in a pit after dropping a seed into it are 2 or 3, its seeds are captured and added to the score of the player.
We selected 5 projects back in May, and the 5 students and their mentors have now been working on their projects for almost two months. We omitted to announce the projects formally (sorry about that!), but this first progress report written by each student will make up for it by giving a direct glimpse into their work.
Boffins in Finland have scanned the open-source software libraries in the Python Package Index, better known as PyPI, for security issues and said they found that nearly half contain problematic or potentially exploitable code.
In a research paper distributed via ArXiv, Jukka Ruohonen, Kalle Hjerppe, and Kalle Rindell from the University of Turku describe how they subjected some 197,000 Python packages available through PyPI to a static analysis tool called Bandit and found more than 749,000 instances of at best poor, or at worst insecure, programming.
n Friday, July 30th, the Rust Compiler team had a planning meeting for the August steering cycle.
Every fourth Friday, the Rust compiler team decides how it is going to use its scheduled steering and design meeting time over the next three Fridays.
Security updates have been issued by Debian (libsndfile and openjdk-11), Fedora (php-pear and seamonkey), openSUSE (fastjar and php7), SUSE (php72, qemu, and sqlite3), and Ubuntu (libsndfile, php-pear, and qpdf).
A security researcher released exploit code for a high-severity vulnerability in Linux kernel eBPF (Extended Berkeley Packet Filter) that can give an attacker increased privileges on Ubuntu machines.
Raju Kendre, a first-generation learner from the small village of Pimpri in Maharashtra, bagged the UK’s Chevening Scholarship in June this year and will travel to the country to pursue higher studies. The 27-year-old also runs an NGO, Eklavya, that aims to bring grassroots students into mainstream education. He has helped 125 students like him access higher education in reputed universities in the country.
I first learnt of Hic et Nunc (HEN) in March of 2021, when artist Mario Klingemann began to tweet about the non-fungible token (NFT) platform and the experimental artworks he was minting on the site. I was thinking about how NFTs might reshape the digital economy, while wary of how they could exacerbate the rapid commodification of art and culture. I was also concerned, given how frequently NFTs are written about that there was too much focus on the market versus the actual art. HEN presented itself as a friendly alternative to the hyper-market-driven narrative around NFTs, offering a safe haven for many emerging or experimental artists.
