Fedora Sours On Creative Commons 'No Rights Reserved' License
by Peter Reutemann 27 Jul '22

'Fedora, the popular Linux distribution, will no longer incorporate software licensed under CC0, the Creative Commons "No Rights Reserved" license. In order to support the wide re-use of copyrighted content in new works, CC0 provides authors "a way to waive all their copyright and related rights in their works to the fullest extent allowed by law." The license arose in response to the 1998 Sonny Bono Copyright Term Extension Act (CTEA), which extended the duration of copyright by 20 years at the expense of the public domain. But CC0 explicitly says the licensor does not waive patent rights, which for free and open source software (FOSS) is a potential problem. That means, for instance as described here, if you use CC0-licensed code in your project, and the author of that code later claims your project is infringing a patent they own regarding that code, your defense will be limited. Avoiding the use of CC0-licensed code is one way to steer clear of these so-called submarine patents that could years later torpedo you. In a message to The Fedora Project's mailing list for legal issues, Richard Fontana, a technology lawyer for Red Hat (which sponsors Fedora), explained that while CC0 is cited as a "good license," it won't be for much longer. "We plan to classify CC0 as allowed-content only, so that CC0 would no longer be allowed for code," said Fontana. "This is a fairly unusual change and may have an impact on a nontrivial number of Fedora packages (that is not clear to me right now), and we may grant a carveout for existing packages that include CC0-covered code." Fontana said there's a growing consensus in the FOSS community that licenses without any form of patent licensing or forbearance aren't suitable. CC0, he said, like other Creative Commons licenses, includes a clause that explicitly states no patent rights are waived by the licensor.' -- source: https://linux.slashdot.org/story/22/07/26/2028205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Coding Mistake Made Intel GPUs 100X Slower in Ray Tracing
by Peter Reutemann 26 Jul '22

26 Jul '22

'Intel Linux GPU driver developers have released an update that results in a massive 100X boost in ray tracing performance. This is something to be celebrated, of course. However, on the flip side, the driver was 100X slower than it should have been because of a memory allocation oversight. Tom's Hardware reports: Linux-centric news site Phoronix reports that a fix merged into the open-source Intel Mesa Vulkan driver was implemented by Intel Linux graphics driver engineering stalwart Lionel Landwerlin on Thursday. The developer wryly commented that the merge request, which already landed in Mesa 22.2, would deliver "Like a 100x (not joking) improvement." Intel has been working on Vulkan raytracing support since late 2020, but this fix is better late than never. Usually, the Vulkan driver would ensure temporary memory used for Vulkan raytracing work would be in local memory, i.e., the very fast graphics memory onboard the discrete GPU. A line of code was missing, so this memory allocation housekeeping task wasn't set. Thus, the Vulkan driver would shift ray tracing data to slower offboard system memory and back. Think of the continued convoluted transfers to this slower memory taking place, slowing down the raytracing performance significantly. It turns out, as per our headline, that setting a flag for "ANV_BO_ALLOC_LOCAL_MEM" ensured that the VRAM would be used instead, and a 100X performance boost was the result. "Mesa 22.2, which includes the new code, is due to be branched in the coming days and will be included in a bundle of other driver refinements, which should reach end-users by the end of August," adds the report.' -- source: https://tech.slashdot.org/story/22/07/25/2316244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Review: Framework’s next-gen Laptop follows through on its upgradeable promises
by Peter Reutemann 26 Jul '22

26 Jul '22

'It's one thing to say you're making a fully user-serviceable, upgradeable laptop. It's another thing to actually follow through with it. The original Framework Laptop we reviewed last year did a lot of things right. It's easy to open and work on, the ports can be swapped out to suit your needs, and it's sturdy and well-built enough to stand up to traditional, less-upgradeable-and-repairable ultrabooks like Dell's XPS 13 or Lenovo's ThinkPad X1 Carbon. But making "one surprisingly good laptop" isn't the same as creating a laptop ecosystem with upgradeable, interchangeable, user-serviceable parts. To do that, you need to keep up with new component releases. You need to address the shortcomings of your original design (or even release new revisions) without ending support for or breaking compatibility with previous versions of your design. And your small, independent company needs to continue to exist so it can keep getting all that work done, year after year, for a few years. I can't say what the next year or two will bring, but I can say that the second-generation Framework Laptop is still doing almost everything right. It's a lightly revised version of the original chassis designed around a 12th-generation Intel Core CPU rather than an 11th-gen version, and the motherboard exists as a drop-in upgrade for anyone who has already bought a Framework Laptop. The Framework Laptop does have problems, especially when it comes to battery life. But overall, it's a thoughtfully designed computer that treats do-it-yourselfers and PC builders like adults who can make their own decisions. There still isn't another laptop quite like it.' -- source: https://arstechnica.com/gadgets/2022/07/review-frameworks-next-gen-laptop-f… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

26 Jul '22

Hi everyone We have a meeting on Monday with the following topic: 'Open source software is always about choice. Whereas Windows users can't really do much about the desktop experience that gets dictated by Microsoft, Linux users can choose from a wide variety of desktop environments. Tonight, we will explore a range of these: MATE, Cinnamon, Gnome, KDE, LXDE, XFCE and maybe more. If your favorite environment is not listed, then please join in and demo it!'

Zero-day used to infect Chrome users could pose threat to Edge and Safari users, too
by Peter Reutemann 22 Jul '22

22 Jul '22

'A secretive seller of cyberattack software recently exploited a previously unknown Chrome vulnerability and two other zero-days in campaigns that covertly infected journalists and other targets with sophisticated spyware, security researchers said. CVE-2022-2294, as the vulnerability is tracked, stems from memory corruption flaws in Web Real-Time Communications, an open-source project that provides JavaScript programming interfaces to enable real-time voice, text, and video communications capabilities between web browsers and devices. Google patched the flaw on July 4 after researchers from security firm Avast privately notified the company it was being exploited in watering hole attacks, which infect targeted websites with malware in hopes of then infecting the users known to frequent them. Microsoft and Apple have since patched the same WebRTC flaw in their Edge and Safari browsers, respectively.' -- source: https://arstechnica.com/information-technology/2022/07/exploit-seller-used-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Dell’s XPS 13 Plus Developer Edition gets Ubuntu 22.04 LTS certified
by Peter Reutemann 21 Jul '22

21 Jul '22

'Dell is extending its love for Linux to the Dell XPS 13 Plus. The Developer Edition of the laptop has been Ubuntu 22.04 LTS-certified, Canonical announced today. That means the laptop will be sold starting in August with the latest version of Ubuntu, and owners of the XPS 13 Plus Developer Edition can download Ubuntu 22.04 LTS today (even if they bought it with Windows 11) for guaranteed performance. The XPS 13 Plus Developer Edition is the first 22.04 LTS-certified laptop, joining only some Raspberry Pi devices in certification. However, Dell has been certifying some of its XPS laptops, as well as other machines, for Ubuntu for generations. HP and Lenovo also have Ubuntu-certified systems. Of course, Ubuntu certification means all the components will "work as expected," as Canonical's announcement today put it. Further, Ubuntu LTS certification means the device will have support for at least 10 years. Ubuntu's release cycle page states that LTS (long-term support) releases include 10 years of "Base Package" maintenance and security updates. "Certified devices also include specific software or drivers that differ from the default distribution where required. These are defined in a meta-package that automatically [installs] the optimal configuration of packages, drivers, and kernel to deliver the best experience on that device," Canonical's announcement said.' -- source: https://arstechnica.com/gadgets/2022/07/dells-xps-13-plus-developer-edition… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google, Oracle Cloud Servers Wilt in UK Heatwave, Take Down Websites
by Peter Reutemann 20 Jul '22

20 Jul '22

'Cloud services and servers hosted by Google and Oracle in the UK have dropped offline due to cooling issues as the nation experiences a record-breaking heatwave. From a report: When the mercury hit 40.3C (104.5F) in eastern England, the highest ever registered by a country not used to these conditions, datacenters couldn't take the heat. Selected machines were powered off to avoid long-term damage, causing some resources, services, and virtual machines to became unavailable, taking down unlucky websites and the like. Multiple Oracle Cloud Infrastructure resources are offline, including networking, storage, and compute provided by its servers in the south of UK. Cooling systems were blamed, and techies switched off equipment in a bid to prevent hardware burning out, according to a status update from Team Oracle. "As a result of unseasonal temperatures in the region, a subset of cooling infrastructure within the UK South (London) Data Centre has experienced an issue," Oracle said on Tuesday at 1638 UTC. "As a result some customers may be unable to access or use Oracle Cloud Infrastructure resources hosted in the region.' -- source: https://it.slashdot.org/story/22/07/19/204256 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Denmark Bans Chromebooks, Google Workspace In Schools Over Data Transfer Risks
by Peter Reutemann 20 Jul '22

20 Jul '22

'Denmark is effectively banning Google's services in schools, after officials in the municipality of Helsingor were last year ordered to carry out a risk assessment around the processing of personal data by Google. TechCrunch reports: In a verdict published last week, Denmark's data protection agency, Datatilsynet, revealed that data processing involving students using Google's cloud-based Workspace software suite -- which includes Gmail, Google Docs, Calendar and Google Drive -- "does not meet the requirements" of the European Union's GDPR data privacy regulations. Specifically, the authority found that the data processor agreement -- or Google's terms and conditions -- seemingly allow for data to be transferred to other countries for the purpose of providing support, even though the data is ordinarily stored in one of Google's EU data centers. Google's Chromebook laptops, and by extension Google Workspace, are used in schools across Denmark. But Datatilsynet focused specifically on Helsingor for the risk assessment after the municipality reported a "breach of personal data security" back in 2020. While this latest ruling technically only applies to schools in Helsingor for now, Datatilsynet notes that many of the conclusions it has reached will "probably apply to other municipalities" that use Google Chromebooks and Workspace. It added that it expects these other municipalities "to take relevant steps" off the back of the decision it reached in Helsingor. The ban is effective immediately, but Helsingor has until August 3 to delete user data. A Google spokesperson told TechCrunch in a statement: "We know that students and schools expect the technology they use to be legally compliant, responsible, and safe. That's why for years, Google has invested in privacy best practices and diligent risk assessments, and made our documentation widely available so anyone can see how we help organizations to comply with the GDPR. Schools own their own data. We only process their data in accordance with our contracts with them. In Workspace for Education, students' data is never used for advertising or other commercial purposes. Independent organizations have audited our services, and we keep our practices under constant review to maintain the highest possible standards of safety and compliance."' -- source: https://news.slashdot.org/story/22/07/18/2059204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Disentangling The Debian Derivatives: Which Should You Use?
by Lawrence D'Oliveiro 19 Jul '22

19 Jul '22

Intro to just a few <https://www.theregister.com/2022/07/18/disentangling_the_debian_derivatives/> members of the sprawling family of Debian derivatives. I think one of the reasons it has spawned so many offshoots is because the maintainers have made a point of ensuring the tools they use to create the distro itself are easy to use, adapt and configure, not just for themselves, but for others, too.

Servers running Digium Phones VoiP software are getting backdoored
by Peter Reutemann 19 Jul '22

19 Jul '22

'Servers running the open source Asterisk communication software for Digium VoiP services are under attack by hackers who are managing to commandeer the machines to install web shell interfaces that give the attackers covert control, researchers have reported. Researchers from security firm Palo Alto Networks said they suspect the hackers are gaining access to the on-premises servers by exploiting CVE-2021-45461. The critical remote code-execution flaw was discovered as a zero-day vulnerability late last year, when it was being exploited to execute malicious code on servers running fully updated versions of Rest Phone Apps, aka restapps, which is a VoiP package sold by a company called Sangoma. The vulnerability resides in FreePBX, the world's most widely used open source software for Internet-based Private Branch Exchange systems, which enable internal and external communications in organizations' private internal telephone networks. CVE-2021-45461 carries a severity rating of 9.8 out of 10 and allows hackers to execute malicious code that takes complete control of servers.' -- source: https://arstechnica.com/information-technology/2022/07/servers-running-digi… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 (office) +64 (7) 577-5304 (home office) https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
