Vivaldi Integrates Mastodon In Its Desktop Browser
by Peter Reutemann 09 Dec '22

09 Dec '22

'Vivaldi recently became the first browser to have its own Mastodon instance, Vivaldi Social. Now, the new version on the desktop is the first to integrate Mastodon into the browser itself, along with the ability to pin tab groups and other UI improvements. From a blog post: We believe in providing alternatives to Big Tech while putting your privacy first and launched Vivaldi Social, our Mastodon instance. And today we are integrating Vivaldi Social into the sidebar of our desktop browser becoming the first browser to offer this functionality. The new version -- Vivaldi 5.6 -- also allows you to pin your tab stacks. We've added a new private search engine You.com for select countries, helping to broaden your choices for searching the web. Vivaldi's sidebar of icons links to a number of utility functions. And now it integrates Vivaldi Social, our Mastodon instance.

Xfce dialog buttons in header
by Peter Reutemann 09 Dec '22

09 Dec '22

Hi everyone Since moving to Xfce, I've been a bit annoyed at my muscle memory as I now have to click on Save/Load/Cancel buttons in the header of save/load dialogs instead of the bottom right. Apparently, I'm not the only dinosaur unhappy about this change, having to move the mouse so far between file format combobox and save button... With the following command, you can move the buttons back to the bottom: xfconf-query -c xsettings -p /Gtk/DialogsUseHeader -s false Found here: https://forums.linuxmint.com/viewtopic.php?p=2039043&sid=a6eeaaa02b60fe9ddd… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Chrome Gets Memory and Energy Saver Modes
by Peter Reutemann 09 Dec '22

09 Dec '22

'Google today announced two new performance settings in its Chrome browser: Memory Saver and Energy Saver. From a report: The Memory Saver mode promises to reduce Chrome's memory usage by up to 30% by putting inactive tabs to sleep. The tabs will simply reload when you need them again. The Energy Saver mode, meanwhile, limits background activity and visual effects for sites with animations and videos when your laptop's battery level drops below 20%.' -- source: https://tech.slashdot.org/story/22/12/08/1723207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Amazon Joins Open Invention Network
by Peter Reutemann 08 Dec '22

08 Dec '22

'Amazon and Amazon Web Services (AWS) have joined the Open Invention Network (OIN) -- the world's largest patent non-aggression consortium. ZDNet reports: OIN has long protected Linux and Linux-related software from patent aggression by rival companies. With the recent increase in patent troll attacks, the OIN is also defending companies from these assaults. This is a natural move for Amazon. Besides relying on Linux and open-source software both for its retail and cloud businesses, Amazon has a strict policy against patent infringement, and users who engage in this behavior can have their listings removed or accounts deleted. Nevertheless, like all large companies, Amazon has also been sued for patent violations. Joining the OIN simply makes good business sense. Nithya Ruff, the Amazon Open Source Program Office director, added: "Linux and open source are essential to many of our customers and a key driver of innovation across Amazon. We are proud to support a broad range of open-source projects, foundations, and partners, and we are committed to the long-term success and sustainability of open source as a whole. By joining OIN, we are continuing to strengthen open source communities and helping to ensure technologies like Linux remain thriving and accessible to everyone."' -- source: https://news.slashdot.org/story/22/12/07/2224237 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Four-Person Dev Team Gets Apple's M-Series GPU Working On Linux
by Peter Reutemann 08 Dec '22

08 Dec '22

'Ars Technica: For the brave people running Linux on Apple Silicon, their patience has paid off. GPU drivers that provide desktop hardware acceleration are now available in Asahi Linux, unleashing more of the M-series chips' power. It has taken roughly two years to reach this alpha-stage OpenGL driver, but the foundational groundwork should result in faster progress ahead, writes project leads Alyssa Rosenzweig and Asahi Lina. In the meantime, the drivers are "good enough to run a smooth desktop experience and some games." The drivers offer non-conformance-tested OpenGL 2.1 and OpenGL ES 2.0 support for all M-series Apple devices. That's enough for desktop environments and older games running at 60 frames per second at 4K. But the next target is Vulkan support. OpenGL work is being done "with Vulkan in mind," Lina writes, but some OpenGL support was needed to get desktops working first. There's a lot more you can read about the interplay between OpenGL, Vulkan, and Zink in Asahi's blog post.' -- source: https://tech.slashdot.org/story/22/12/07/2138241 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Syntax Errors Are the Doom of Us All, Including Botnet Authors
by Peter Reutemann 07 Dec '22

07 Dec '22

'KmsdBot, a cryptomining botnet that could also be used for denial-of-service (DDOS) attacks, broke into systems through weak secure shell credentials. It could remotely control a system, it was hard to reverse-engineer, didn't stay persistent, and could target multiple architectures. KmsdBot was a complex malware with no easy fix. That was the case until researchers at Akamai Security Research witnessed a novel solution: forgetting to put a space between an IP address and a port in a command. And it came from whoever was controlling the botnet. With no error-checking built in, sending KmsdBot a malformed command -- like its controllers did one day while Akamai was watching -- created a panic crash with an "index out of range" error. Because there's no persistence, the bot stays down, and malicious agents would need to reinfect a machine and rebuild the bot's functions. It is, as Akamai notes, "a nice story" and "a strong example of the fickle nature of technology." KmsdBot is an intriguing modern malware. It's written in Golang, partly because Golang is difficult to reverse-engineer. When Akamai's honeypot caught the malware, it defaulted to targeting a company that created private Grand Theft Auto Online servers. It has a cryptomining ability, though it was latent while the DDOS activity was running. At times, it wanted to attack other security companies or luxury car brands.' -- source: https://it.slashdot.org/story/22/12/06/1552228 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Company 'Hijacks' Blender's CC BY-Licensed Film, YouTube Strikes User
by Peter Reutemann 06 Dec '22

06 Dec '22

'TorrentFreak: The Blender Institute develops Blender, a free and open source 3D graphics tool used to create animated films. Sintel and Big Buck Bunny are among Blender's most recognizable titles and due to Creative Commons licensing (CC BY), they are widely shared, used, remixed and reshared. According to original Blender creator Ton Roosendaal, "Open licenses are essential for sharing our films and their source material." Right now, a company is claiming that Blender's free content is actually their content and as a result, must be immediately removed from the internet. We're talking about content that was created with Blender's explicit blessing but even after multiple appeals, not even YouTube will see reason. Bruno Fernandez-Ruiz is the co-founder and CTO at AI-focused driver safety company, Nexar. On Sunday he informed TorrentFreak that he's also an independent film composer and producer, working with music production libraries, and distributing to the main music platforms. TorrentFreak contacted Bruno after noticing a post he made on a music production forum. He wrote that after uploading a video containing a clip from the Blender movie Caminandes 3 -- Llamigos, YouTube notified him that a rightsholder had filed a copyright complaint, his video had been taken down, and a copyright strike had been issued to his account. The complaint, sent by Uzbekistan-based media/news company ZO'R TV, was not the result of automatic matching under Content ID. It was filed as a formal DMCA notice, meaning that someone probably reviewed the details before sending the complaint. The notice claimed that Bruno had infringed ZO'R TV's copyrights by reproducing content (6:21 to 8:26) from this YouTube video published in 2018. Since the content in question is obviously from Blender's film Caminandes 3, ZO'R TV was in no position to issue a DMCA notice. On that basis, Bruno followed the recognized procedure by sending a DMCA counternotice to YouTube. It didn't go well. After filing his counternotice with YouTube, Bruno was informed that since he'd provided insufficient information, YouTube could not process it. However, YouTube did inform Bruno of the risks of filing a counternotice, including that his name could be sent to the claimant, ZO'R TV in this case. Determined to have his video restored, Bruno accepted the risks and sent another counternotice to YouTube. This time there was no indication that the counternotice was deficient. YouTube thanked him for filing it -- but still declined to process it. YouTube's email advised Bruno that counternotices should only be filed in case of a mistake or misidentification. Consulting with a lawyer first might be helpful, YouTube added. After three attempts to restore the video and have the copyright strike removed, YouTube responded once again. The message contained yet more disappointment for Bruno. "Based on the information that you have provided, it appears that you do not have the necessary rights to post the content on YouTube. Therefore, we regretfully cannot honor your request," it advised. This signaled the end of the debate as far as YouTube was concerned and by rejecting Bruno's right to send a counternotice, the platform denied him an opportunity to have the video restored, stand up for Blender's rights, and get the strike removed. After notifying Blender of the situation, Blender developed Ton Roosendaal replied, saying the company has "no staff here available to go after situations like this" but suggested they could "escalate it to the Creative Commons organization." "After all, it's their mission," he added.' -- source: https://news.slashdot.org/story/22/12/05/2212216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Mint 20.2: Mate / GTK issue?
by Peter Reutemann 05 Dec '22

05 Dec '22

Hi everyone Just in case some one else encounters this problem... Last Friday, I installed the latest kernel update on my Linux Mint 20.2 MATE edition and rebooted the first time in a few weeks. After logging back in, I noticed that the Xorg process was using almost one core on my laptop. This wasn't the case when waiting at the login prompt (i.e., lightdm). Starting my file browser of choice, GTK version of double-command, (package: doublecmd-gtk), seemed to grab another core. Downgrading of Xorg or using an older kernel had no impact, unfortunately. When switching to XFCE4 for my session today, I didn't experience that high CPU load problem anymore. I also switched to the QT version of double-commander (package: doublecmd-qt). Not really solving the problem, more like side-stepping it, but at least I get can work done again, without my laptop fan going hard out all day... And I've used XFCE in the past. :-) Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Today’s New Word: “Cyberdeck”
by Lawrence D'Oliveiro 04 Dec '22

04 Dec '22

What is a “cyberdeck”? According to <https://hackaday.com/tag/cyberdeck/>, it’s basically a style of home-built computer with futuristic/sci-fi/cyberpunk overtones. The name comes from (what else) a William Gibson novel. It seems common to use a Raspberry π as the beating heart, with a custom 3D-printed case around it plus other suitably interesting-looking parts. Angles seem preferable to curves, with asymmetrically-inset polygons very popular. Weird and wacky keyboard layouts are a bonus. The diminutive size of the Raspberry π leaves plenty of room for experimentation. We can build the future-that-never-was! We have the technology now.
