CentOS Is Gone -- But RHEL Is Now Free For Up To 16 Production Servers
by Peter Reutemann 06 Mar '21

06 Mar '21

'Ars Technica: Last month, Red Hat caused a lot of consternation in the enthusiast and small business Linux world when it announced the discontinuation of CentOS Linux. Long-standing tradition -- and ambiguity in Red Hat's posted terms -- led users to believe that CentOS 8 would be available until 2029, just like the RHEL 8 it was based on. Red Hat's early termination of CentOS 8 in 2021 cut eight of those 10 years away, leaving thousands of users stranded. Red Hat's December announcement of CentOS Stream -- which it initially billed as a "replacement" for CentOS Linux -- left many users confused about its role in the updated Red Hat ecosystem. As of February 1, 2021, Red Hat will make RHEL available at no cost for small-production workloads -- with "small" defined as 16 systems or fewer. This access to no-cost production RHEL is by way of the newly expanded Red Hat Developer Subscription program, and it comes with no strings -- in Red Hat's words, "this isn't a sales program, and no sales representative will follow up." Red Hat is also expanding the availability of developer subscriptions to teams, as well as individual users. Moving forward, subscribing RHEL customers can add entire dev teams to the developer subscription program at no cost. This allows the entire team to use Red Hat Cloud Access for simplified deployment and maintenance of RHEL on well-known cloud providers, including AWS, Google Cloud, and Microsoft Azure.' -- source: https://linux.slashdot.org/story/21/01/20/2016202 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Torvalds warns the world: Don’t use the Linux 5.12-rc1 kernel
by Peter Reutemann 06 Mar '21

06 Mar '21

'In a message to the Linux Kernel Mailing List yesterday, founding developer Linus Torvalds warned the world not to use the 5.12-rc1 kernel in his public git tree. Hey peeps - some of you may have already noticed that in my public git tree, the "v5.12-rc1" tag has magically been renamed to "v5.12-rc1-dontuse". It's still the same object, it still says "v5.12-rc1" internally and it is still is signed by me, but the user-visible name of the tag has changed. As it turns out, when Linus Torvalds flags some code dontuse, he really means it—the problem with this 5.12 release candidate broke swapfile handling in a very unpleasant way. Specifically, the updated code would lose the proper offset pointing to the beginning of the swapfile. Again, in Torvalds' own words, "swapping still happened, but it happened to the wrong part of the filesystem, with the obvious catastrophic end results."' -- source: https://arstechnica.com/gadgets/2021/03/psa-linux-folks-stay-away-from-the-… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Windows.com Bitsquatting Hack Can Wreak 'Unknown Havoc' On PCs
by Peter Reutemann 05 Mar '21

05 Mar '21

'Ars Technica: Bitflips are events that cause individual bits stored in an electronic device to flip, turning a 0 to a 1 or vice versa. Cosmic radiation and fluctuations in power or temperature are the most common naturally occurring causes. Research from 2010 estimated that a computer with 4GB of commodity RAM has a 96 percent chance of experiencing a bitflip within three days. An independent researcher recently demonstrated how bitflips can come back to bite Windows users when their PCs reach out to Microsoft's windows.com domain. Windows devices do this regularly to perform actions like making sure the time shown in the computer clock is accurate, connecting to Microsoft's cloud-based services, and recovering from crashes. Remy, as the researcher asked to be referred to, mapped the 32 valid domain names that were one bitflip away from windows.com. Of the 32 bit-flipped values that were valid domain names, Remy found that 14 of them were still available for purchase. This was surprising because Microsoft and other companies normally buy these types of one-off domains to protect customers against phishing attacks. He bought them for $126 and set out to see what would happen. Over the course of two weeks, Remy's server received 199,180 connections from 626 unique IP addresses that were trying to contact ntp.windows.com. By default, Windows machines will connect to this domain once per week to check that the time shown on the device clock is correct. What the researcher found next was even more surprising. "The NTP client for windows OS has no inherent verification of authenticity, so there is nothing stopping a malicious person from telling all these computers that it's after 03:14:07 on Tuesday, 19 January 2038 and wreaking unknown havoc as the memory storing the signed 32-bit integer for time overflows," he wrote in a post summarizing his findings. "As it turns out though, for ~30% of these computers doing that would make little to no difference at all to those users because their clock is already broken."' -- source: https://tech.slashdot.org/story/21/03/04/2152239 I wonder whether anyone has tested apt-get in regards to this...

US Issues Warning After Microsoft Says China Hacked Its Mail Server Program
by Peter Reutemann 05 Mar '21

05 Mar '21

'NBC News: The U.S. has issued an emergency warning after Microsoft said it caught China hacking into its mail and calendar server program, called Exchange. The perpetrator, Microsoft said in a blog post, is a hacker group that the company has "high confidence" is working for the Chinese government and primarily spies on American targets. The latest software update for Exchange blocks the hackers, prompting the U.S. Cybersecurity and Infrastructure Security Agency to issue a rare emergency directive that requires all government networks do so. CISA, the U.S.'s primary defensive cybersecurity agency, rarely exercises its authority to demand the entire U.S. government take protective steps to protect its cybersecurity. The move was necessary, the agency announced, because the Exchange hackers are able "to gain persistent system access." All government agencies have until noon Friday to download the latest software update. In a separate blog post, Microsoft Vice President Tom Burt wrote that the hackers have recently spied on a wide range of American targets, including disease researchers, law firms and defense contractors. There was no immediate indication that the hack led to significant exploitation of U.S. government computer networks. But the announcement marks the second instance in recent months that the U.S. scrambled to address a widespread hacking campaign believed be the work of foreign government spies.' -- source: https://it.slashdot.org/story/21/03/04/022226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

'Google Chrome releases will soon arrive more frequently than ever. >From a report: In an announcement today, Google said it is updating the Chrome release schedule for the first time in over a decade. For a cool 10+ years now, Chrome stable releases have shipped every 6 weeks with new features, security fixes, etc. With improvements to testing and release processes, Google has realized that it can shorten the release cycle and will do so in Q3 of this year. Starting with Chrome 94, Google will move to a 4-week milestone release cycle. Freaked out at the possibility that Google might break features, remove things you like, or cause other issues with so many releases? Don't worry, Google is also introducing an Extended Stable release that will see milestone updates every 8 weeks.

Privacy-first Browser Brave Now Has Its Own Google Search Rival
by Peter Reutemann 04 Mar '21

04 Mar '21

'Two years after publicly launching a privacy-focussed browser, Brave, founded by former Mozilla executive Brendan Eich, is taking on Google's search business, too. From a report: The announcement of Brave Search puts the upstart in the rare position of taking on both Google's browser and search dominance. Eich says that Brave Search, which has opened a waitlist and will launch in the first half of this year, won't track or profile people who use it. "Brave already has a default anonymous user model with no data collection at all," he says adding this will continue in its search engine. No IP addresses will be collected and the company is exploring how it can create both a paid, ad-free search engine and one that comes with ads. But building a search engine isn't straightforward. [...] Eich says Brave isn't starting its search engine or index from scratch and won't be using indexes from Bing or other tech firms. Instead Brave has purchased Tailcat, an offshoot of German search engine Cliqz, which was owned by Hubert Burda Media and closed down last year. The purchase includes an index of the web that's been created by Tailcat and the technology that powers it. Eich says that some users will be given the ability to opt-in to anonymous data collection to help fine-tune search results. "What Tailcat does is it looks at a query log and a click log anonymously," Eich says. "These allow it to build an index, which Tailcat has done and already did at Cliqz, and it's getting bigger." He admits that the index will not be anywhere near as deep as Google's but that the top results it surfaces are largely the same.' -- source: https://search.slashdot.org/story/21/03/03/1643231 Interesting that they didn't simply use DuckDuckGo...

Microsoft Launches Power Fx, a New Open Source Low-Code Language
by Peter Reutemann 03 Mar '21

03 Mar '21

'Microsoft today announced Power Fx, a new low-code language that "will become the standard for writing logic customization across Microsoft's own low-code Power Platform," reports TechCrunch. "[S]ince the company is open-sourcing the language, Microsoft also hopes others will implement it as well and that it will become the de facto standard for these kinds of use cases." From the report: Microsoft says the language was developed by a team led by Vijay Mital, Robin Abraham, Shon Katzenberger and Darryl Rubin. Beyond Excel, the team also took inspiration from tools and languages like Pascal, Mathematica and Miranda, a functional programming language developed in the 1980s. Microsoft plans to bring Power Fx to all of its low-code platforms, but given the focus on community, it'll start making appearances in Power Automate, Power Virtual Agents and elsewhere soon. But the team clearly hopes that others will adopt it as well. Low-code developers will see it pop up in the formula bars of products like Power Apps Studio, but more sophisticated users will also be able to use it to go to Visual Studio Code and build more complex applications with it. As the team noted, it focused on not just making the language Excel-like but also having it behave like Excel -- or like a REPL, for you high-code programmers out there. That means formulas are declarative and instantly recalculate as developers update their code.

Google-free /e/ OS is now selling preloaded phones in the US, starting at $380
by Peter Reutemann 03 Mar '21

03 Mar '21

'/e/ OS, the "open-source, pro-privacy, and fully degoogled" fork of Android, is coming to Canada and the USA. Of course, you've always been able to download the software in any region, but now (as first spotted by It's Foss News) the e Foundation will start selling preloaded phones in North America. Previously, /e/ only did business in Europe. Like normal, the e Foundation's smartphone strategy is to sell refurbished Samsung devices with /e/ preloaded. In the US, there are only two phones right now: the Galaxy S9 for $379.99 or a Galaxy S9+ for $429.99. North Americans still have reason to be jealous of Europe, where you can get /e/ preloaded on a Fairphone, which is also Europe-exclusive. These Samsung phones are used devices, but the site says the devices have "been checked and reconditioned to be fully working at our partner's facilities." The phones have a one-year warranty and are described as "Good-as-New" with "no surprises." An /e/ device means you'll be getting a fork of Android 10, and for ongoing support, the e Foundation says, "We aim to support with at least 3 years of software updates and security patches."' -- source: https://arstechnica.com/gadgets/2021/03/google-free-e-os-is-now-selling-pre… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linus Torvalds Went Six Days Without Electricity, Swears Smaller 5.12 Kernel Is Co-Incidental
by Peter Reutemann 03 Mar '21

03 Mar '21

'Linux overlord Linus Torvalds has revealed that inclement weather in the USA meant he recently endured six electricity-free days in his Portland, Oregon, home during which he was unable to tend to the kernel. As a result he therefore pondered adding an extra week to the merge window for version 5.12 of the Linux kernel. The Register reports: "As you can tell, I didn't do that," he said in his State of The Kernel update that announced release candidate one of the new kernel cut. "To a large part because people were actually very good about sending in their pull requests, so by the time I finally got power back, everything was nicely lined up and I got things merged up ok." It wasn't just penguinistas behaving well that helped. Torvalds said this version of the kernel has received around 10,000 commits. That's rather fewer than the 12,000 or 13,000 he usually sees. In case anyone was inconvenienced by blackout-induced inability to merge, Torvalds said he's open to help any kernel devs for whom his unavailability caused problems but is not open to all late pulls. Torvalds rated the new release as offering "a fair amount of historical cleanup" on account of "removing the legacy OPROFILE support (the user tools have been using the "perf" interface for years), and removing several legacy SoC platforms and various drivers that no longer make any sense." Among the big inclusions in 5.12 are Clang Link-Time Optimizations, which make for better compiler performance, and support for Intel's eASIC NX5 silicon that aims to offer an alternative to FPGAs in edge and cloud applications. Qualcomm's Snapdragon 888 5G SoC also gains support.

Go Malware is Now Common, Having Been Adopted by Both APTs and E-crime Groups
by Peter Reutemann 02 Mar '21

02 Mar '21

'The number of malware strains coded in the Go programming language has seen a sharp increase of around 2,000% over the last few years, since 2017, cybersecurity firm Intezer said in a report published recently. From a report: The company's findings highlight and confirm a general trend in the malware ecosystem, where malware authors have slowly moved away from C and C++ to Go, a programming language developed and launched by Google in 2007. While the first Go-based malware was detected in 2012, it took, however, a few years for Golang to catch on with the malware scene. "Before 2019, spotting malware written in Go was more a rare occurrence and during 2019 it became a daily occurrence," Intezer said in its report. But in the new report, Golang (as it's often also referred to instead of Go) has broken through and has been widely adopted. It is used by nation-state hacking groups (also known as APTs), cybercrime operators, and even security teams alike, who often used it to create penetration-testing toolkits.' -- source: https://it.slashdot.org/story/21/03/01/1545257 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

First Fully Weaponized Spectre Exploit Discovered Online
by Peter Reutemann 02 Mar '21

02 Mar '21

'Catalin Cimpanu, reporting for The Record: A fully weaponized exploit for the Spectre CPU vulnerability was uploaded on the malware-scanning website VirusTotal last month, marking the first time a working exploit capable of doing actual damage has entered the public domain. The exploit was discovered by French security researcher Julien Voisin. It targets Spectre, a major vulnerability that was disclosed in January 2018. [...] The vulnerability, which won a Pwnie Award in 2018 for one of the best security bug discoveries of the year, was considered a milestone moment in the evolution and history of the modern CPU. Its discovery, along with the Meltdown bug, effectively forced CPU vendors to rethink their approach to designing processors, making it clear that they cannot focus on performance alone, to the detriment of data security. Software patches were released at the time, but the Meltdown and Spectre disclosures forced Intel to rethink its entire approach to CPU designs going forward. At the time, the teams behind the Meltdown and Spectre bugs published their work in the form of research papers and some trivial proof-of-concept code to prove their attacks. Shortly after the Meltdown and Spectre publications, experts at AV-TEST, Fortinet, and Minerva Labs spotted a spike in VirusTotal uploads for both CPU bugs. While initially there was a fear that malware authors might be experimenting with the two bugs as a way to steal data from targeted systems, the exploits were classified as harmless variations of the public PoC code published by the Meltdown and Spectre researchers and no evidence was found of in-the-wild attacks. But today, Voisin said he discovered new Spectre exploits -- one for Windows and one for Linux -- different from the ones before. In particular, Voisin said he found a Linux Spectre exploit capable of dumping the contents of /etc/shadow, a Linux file that stores details on OS user accounts.' -- source: https://it.slashdot.org/story/21/03/01/1851240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Mint Developers Will Force Updates on Users Like Microsoft Does with Windows 10
by Peter Reutemann 02 Mar '21

02 Mar '21

'Last month, the Linux Mint team published a post on the organization's official blog about the importance of installing security updates on machines running the Linux distribution. The essence of the post was that a sizeable number of Linux Mint devices was running outdated applications, packages or even an outdated version of the operating system itself. A sizeable number of devices run on Linux Mint 17.x, according to the blog post, a version of Linux Mint that reached end of support in April 2019. A new blog post, published yesterday, provides information on how the team plans to reduce the update reluctance of Linux Mint users. Next to showing reminders to users, Linux Mint's Update Manager may enforce some of the updates according to the blog post. "In some cases the Update Manager will be able to remind you to apply updates. In a few of them it might even insist." Upcoming versions will provide information on the implementation, how the "insisting" part may look like, and whether the installation of updates will be enforced. All of this boils down to a single question: how far should operating system developers go when it comes to updates? BetaNews adds: "And now, it seems the Linux Mint developers are taking a page out of Microsoft's playbook by planning to force some updates on its users. Yes, folks, Linux Mint is becoming more like Windows 10."' -- source: https://linux.slashdot.org/story/21/03/01/2032216 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Exploring the Open Source That Really Goes Into a RISC-V Chip

Finally we might be about to see open-source from the silicon to the user interface, or so goes the optimistic promise. In fact the real story is considerably more complex than that, and it's a topic [Andreas Speiss] explores in a video that looks at the issue with a wide lens... nickwinlund77 writes: The YouTube video starts out with a good general history of competition between large businesses over architectures and embracing the standards for tech which many of us have depended on throughout the years. The video then gets into the technical specifics of the ESP32-C3. Hackaday adds: His conclusion is that while a truly open-source RISC-V chip is entirely possible (as demonstrated with a cameo Superconference badge appearance), the importance of the RISC-V ISA is in its likely emergence as a heavyweight counterbalance to ARM's dominance in the sector.

Red Hat Introduces Free RHEL for Open-Source Organizations
by Peter Reutemann 01 Mar '21

01 Mar '21

'ZDNet brings an update about the future of Red Hat Enterprise Linux: When Red Hat, CentOS's Linux parent company, announced it was "shifting focus from CentOS Linux, the rebuild of Red Hat Enterprise Linux (RHEL), to CentOS Stream," CentOS users were not happy. Now, in an effort to mollify them and to keep its promise to open-source organizations, Red Hat is introducing a new, free RHEL for Open Source Infrastructure. If your non-profit organization, project, standard body, or foundation is "engaged with open source," you can get a free RHEL subscription via this program. Earlier this year, Red Hat introduced no-cost RHEL for small production workloads and for customer development teams... Jason Brooks, a Red Hat Open Source Program Office Manager explained: Supporting the open-source software ecosystem is a core objective for Red Hat... We know that we are part of a larger, interdependent ecosystem that we benefit from and which we do our best to foster and support. This support comes in many forms, but often includes helping open source software projects, foundations, and standards bodies access enterprise technologies for development and testing. We frequently provide no-cost access to RHEL to these groups, but the process isn't as formalized, consistent, accessible, or transparent as we'd like it to be. With the announcement that we will be shifting our resources to CentOS Stream at the end of 2021, we want to make sure that those organizations engaged with open source have access to RHEL as they build and test the future of open-source software... The GNOME Foundation's executive director Neil McGovern, said: As a non-profit, we rely on donations to help us achieve our goal of a world where everyone is empowered by technology they can trust. RHEL subscriptions are an essential part of this. With full operating system management and security updates, we can concentrate on the services we provide to GNOME users and developers without having to worry about the underlying systems. Red Hat has generously provided these services to GNOME at zero cost for years, and we look forward to continuing our relationship for a long time to come. GNOME is also the default desktop in RHEL Workstation.' -- source: https://linux.slashdot.org/story/21/02/27/0235247 Chdeers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Brave Privacy Bug Exposed Tor Onion URLs To Your DNS Provider
by Peter Reutemann 01 Mar '21

01 Mar '21

'Brave Browser had a privacy issue that leaked the Tor onion URL addresses you visited to your locally configured DNS server, "exposing the dark web websites you visit...", writes Bleeping Computer. Long-time Slashdot reader AmiMoJo quotes their report: To access Tor onion URLs, Brave added a "Private Window with Tor" mode that acts as a proxy to the Tor network. When you attempt to connect to an onion URL, your request is proxied through volunteer-run Tor nodes who make the request for you and send back the returned HTML. Due to this proxy implementation, Brave's Tor mode does not directly provide the same level of privacy as using the Tor Browser. When using Brave's Tor mode, it should forward all requests to the Tor proxies and not send any information to any non-Tor Internet devices to increase privacy. However, a bug in Brave's "Private window with Tor" mode is causing the onion URL for any Tor address you visit to also be sent as a standard DNS query to your machine's configured DNS server. This bug was first reported in a Reddit post and later confirmed by James Kettle, the Director of Research at PortSwigger. BleepingComputer has also verified the claims by using Wireshark to view DNS traffic while using Brave's Tor mode. Brave has since released an update which fixes the bug.' -- source: https://yro.slashdot.org/story/21/02/27/221208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Introducing Crowdsec: a Modernized, Collaborative Massively Multiplayer Firewall
by Peter Reutemann 01 Mar '21

01 Mar '21

'CrowdSec is a massively multiplayer firewall designed to protect Linux servers, services, containers, or virtual machines exposed on the Internet with a server-side agent. It was inspired by Fail2Ban and aims to be a modernized, collaborative version of that intrusion-prevention tool. CrowdSec is free and open-source (under an MIT License), with the source code available on GitHub. It uses a behavior analysis system to qualify whether someone is trying to hack you, based on your logs. If your agent detects such aggression, the offending IP is then dealt with and sent for curation. If this signal passes the curation process, the IP is then redistributed to all users sharing a similar technological profile to 'immunize' them against this IP. The goal is to leverage the power of the crowd to create a real-time IP reputation database. As for the IP that aggressed your machine, you can choose to remedy the threat in any manner you feel appropriate. Ultimately, CrowdSec leverages the power of the community to create an extremely accurate IP reputation system that benefits all its users. It was clear to the founders that Open Source was going to be one of the main pillars of CrowdSec. The project's founders have been working on open-source projects for decades — they didn't just jump on the train. Rather, they are strong Open Source believers. They believe that the crowd is key to the mass hacking plague we are experiencing, and that Open Source is the best lever to create a community and have people contribute their knowledge to the project, ultimately make it better and more secure. The solution recently turned 1.x, introducing a major architectural change: the introduction of a local REST API.' -- source: https://linux.slashdot.org/story/21/02/27/2215223 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Firefox's Total Cookie Protection Aims To Stop Tracking Between Multiple Sites
by Peter Reutemann 24 Feb '21

24 Feb '21

'As part of its war on web tracking, Mozilla is adding a new tool to Firefox aimed at stopping cookies from keeping tabs on you across multiple sites. From a report: The "Total Cookie Protection" feature is included in the web browser's latest release -- alongside multiple picture-in-picture views -- and essentially works by keeping cookies isolated between each site you visit. Or, in Mozilla's words: "By creating a separate cookie jar for every website." Firefox's new feature pares with last month's network partitioning tool, which works by splitting the Firefox browser cache on a per-website basis to prevent tracking across the web, itself targeted at blocking more stubborn "supercookies." According to Mozilla, these types of cookies are more difficult to delete and block as they are stored in obscure parts of the browser, including in Flash storage, ETags, and HSTS flags. Both tools are available as part of Firefox's enhanced tracking protection suite in "strict mode" on desktop and Android.' -- source: https://news.slashdot.org/story/21/02/23/1513219 -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New TLD For Spammers
by Lawrence D'Oliveiro 21 Feb '21

21 Feb '21

Normally I get only a handful of spam e-mails per day -- greylisting is that effective at keeping most of them out. But over the past couple of days, this moved closer to being a flood like the bad old days, with several dozen coming in over the last 24 hours or so. Doing a quick check, all the ones I looked at were being sent from *.cyou domains. Yes, there really is such a top-level domain now. But given that it seems to be used entirely for spam, it’s easy enough to add a line to my block_sender file: /^.+(a).+\.cyou$/ REJECT

The world’s second-most popular desktop operating system isn’t macOS anymore
by Peter Reutemann 21 Feb '21

21 Feb '21

'For ages now, every annual report on desktop operating system market share has had the same top two contenders: Microsoft's Windows in a commanding lead at number one and Apple's macOS in distant second place. But in 2020, Chrome OS became the second-most popular OS, and Apple fell to third. That's according to numbers from market data firm IDC and a report on IDC's data by publication GeekWire. Chrome OS had passed macOS briefly in individual quarters before, but 2020 was the first full year when Apple's OS took third place. Despite the fact that macOS landed in third, viewing this as an example of Google beating out Apple directly might not be accurate. Rather, it's likely that Chrome OS has been primarily pulling sales and market share away from Windows at the low end of the market. Mac market share actually grew from 6.7 percent in 2019 to 7.5 percent in 2020. Meanwhile, Chrome OS skyrocketed from 6.4 percent in 2019 to 10.8 percent in 2020. Windows fell from 85.4 percent to 80.5 percent.' -- source: https://arstechnica.com/gadgets/2021/02/the-worlds-second-most-popular-desk… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

New browser-tracking hack works even when you flush caches or go incognito
by Peter Reutemann 21 Feb '21

21 Feb '21

'The prospect of Web users being tracked by the sites they visit has prompted several countermeasures over the years, including using Privacy Badger or an alternate anti-tracking extension, enabling private or incognito browsing sessions, or clearing cookies. Now, websites have a new way to defeat all three. The technique leverages the use of favicons, the tiny icons that websites display in users’ browser tabs and bookmark lists. Researchers from the University of Illinois, Chicago said in a new paper that most browsers cache the images in a location that’s separate from the ones used to store site data, browsing history, and cookies. Websites can abuse this arrangement by loading a series of favicons on visitors’ browsers that uniquely identify them over an extended period of time. [...] The attack works against Chrome, Safari, Edge, and until recently Brave, which developed an effective countermeasure after receiving a private report from the researchers. Firefox would also be susceptible to the technique, but a bug prevents the attack from working at the moment.' -- source: https://arstechnica.com/information-technology/2021/02/new-browser-tracking… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Top Banks Join Linux and Open-Source Patent Protection Group
by Peter Reutemann 21 Feb '21

21 Feb '21

'ZDNet reports: When it comes to defending the intellectual property (IP) rights of Linux and open-source software, global leading banks aren't the first businesses to come to mind. Things have changed. Barclays, the London-based global corporate and investment bank, and the TD Bank Group, with its 26-million global customers, have joined the leading open-source IP defense group, the Open Invention Network (OIN). For years, the OIN, the largest patent non-aggression consortium, has protected Linux from patent attacks and patent trolls. Recently, it expanded its scope from core Linux programs and adjacent open-source code by expanding its Linux System Definition. In particular, that means patents relating to the Android Open Source Project (AOSP) 10 and the Extended File Allocation Table exFAT file system are now protected... Besides joining the OIN, Barclay is also joining the LOT Network. This is another fast-growing nonprofit group of companies that aims to stop patent trolls in their tracks. It has more than 1,100 member companies and covers over 2 million patent assets. Why? The "IP and Patentable Innovations Lead" at TD noted that activity from so-called patent assertion entities "continues to trend upward in the banking industry," according to ZDNet. He argues they "have become a tax on business and we're willing to explore any reasonable means to address such risks..."' -- source: https://news.slashdot.org/story/21/02/20/0244211 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux Is Now on Mars, Thanks to NASA's Perseverance Rover
by Peter Reutemann 21 Feb '21

21 Feb '21

'"When NASA's Perseverance rover landed on Mars this week, it also brought the Linux operating system to the Red Planet," reports PC Magazine: The tidbit was mentioned in an interview NASA software engineer Tim Canham gave to IEEE Spectrum. The helicopter-like drone on board the Perseverance rover uses a Linux-powered software framework the space agency open-sourced a few years ago. "This the first time we'll be flying Linux on Mars. We're actually running on a Linux operating system," Canham said. It also might be the first time NASA has brought a Linux-based device to Mars. "There isn't a previous use of Linux that I'm aware of, definitely on the previous rovers," Canham told PCMag in an email. Past Mars rovers have used proprietary OSes, largely from the software company Wind River Systems. The same is true for the Perseverance rover itself; the machine has been installed with Wind River's VxWorks, which was used on past Mars missions. The article also notes that the helicopter-like drone Ingenuity "was built using off-the-shelf parts, including Qualcomm's Snapdragon 801 processor, a smartphone chip." "Ingenuity is purely a technology demonstration," notes ZDNet. "It's not designed to support the Perseverance mission, which is searching for signs of ancient life and collecting rock and dirt samples for later missions to return to Earth. Its mission is to show that it's possible to fly on Mars using commercial off-the-shelf hardware and open-source software."' -- source: https://science.slashdot.org/story/21/02/20/1830240 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

LastPass' Free Tier Will Become a Lot Less Useful Next Month
by Peter Reutemann 17 Feb '21

17 Feb '21

'LastPass is adding new restrictions to its free subscription tier starting March 16th that'll only allow users to view and manage passwords on one category of devices: mobile or computer. From a report: Mobile users will be limited to iOS and Android phones, iPads, Android tablets, and smartwatches. Computer subscribers will be able to use their passwords from Windows, macOS, and Linux desktops and laptops, the LastPass browser extension, and Windows tablets. Users on LastPass' free tier will be asked to pick between the two options the first time they log in after March 16th, and the company says they'll be able to switch between categories up to three times after they've picked. Although customers are restricted to a single category of devices on the free tier, they'll still be able view and manage passwords from an unlimited number of devices within either the mobile or computer category. LastPass says no users will be locked out of their accounts or lose access to their passwords as a result of the changes. As well as restricting its device types, LastPass is also changing the kinds of customer support free tier users will be able to access. From May 17th, free users will lose access to email support, the company announced.' -- source: https://tech.slashdot.org/story/21/02/16/166221 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Dev creeped out after he fired up Ubuntu VM on Azure, was immediately approached by Canonical sales rep
by Peter Reutemann 16 Feb '21

16 Feb '21

'An Azure customer was outraged after finding himself on the receiving end of an unexpected LinkedIn message from Ubuntu maker Canonical last night. The user, Luca Bongiorni, had spun up an instance of the Linux distro on an Azure corporate subscription in order to evaluate some tooling. Sensibly, the subscription is used as a sandbox for the purpose of testing. Upon clicking "Add new VM", the first option was Ubuntu 18.04, according to Bongiorni, which he selected in order to get his Linux kicks. Shortly after, however, a message turned up from an Enterprise Development representative at Ubuntu with the ominous phrase: "I saw that you spun up an Ubuntu image in Azure," and offering to be a point of contact.' -- source: https://www.theregister.com/2021/02/11/microsoft_azure_ubuntu_data_sharing/ Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Happy ENIAC Day
by Lawrence D'Oliveiro 16 Feb '21

16 Feb '21

75 years ago today, the University of Pennsylvania launched ENIAC, the first non-classified programmable digital computer <https://www.theregister.com/2021/02/15/eniac_day/>. (The UK Colossus preceded it, but the existence of that was kept secret for a few more decades.) This was not a “stored-program” machine, at least not at first: programming was initially done using patch cords and switches. You may also like this interview <https://www.youtube.com/watch?v=buAYHonF968> with the late Jean Jennings Bartik, about some of the fun she and her colleagues had programming the ENIAC, and the innovations they came up with. The electronics engineers who built the first computers didn’t think of programming as a very interesting activity, so they left it to women.

History Of VLC
by Lawrence D'Oliveiro 15 Feb '21

15 Feb '21

Found this <https://www.protocol.com/vlc-history-open-source> linked from a report on the new version of VLC, describing the history of the project back to its beginnings. Once upon a time there was “VideoLAN Server” and “VideoLAN Client”, but today everything has been rolled into a single “VLC” program. Of course it’s been in the sights of Intellectual Property lawyers for a long time: VLC's success also put it on the radar of patent lawyers, who started to send the VideoLAN team a growing number of legal threats, looking to extract licensing fees. Over the years, the VLC team received hundreds such legal threats over alleged patent violations. Virtually all of them were without merit, according to Kempf. Many were based on U.S. software patents that weren't easily enforceable in Europe. Others were citing technology that VLC was using even before companies tried to patent it. "No one is checking whether these patents are valid," Kempf said. "It's a complete mafia; it's protection money." The open-source x264 codec implementation was also an offshoot of VLC. And Jean-Baptiste Kempf says he could have done those software-bundling deals where unwary users get all kinds of things installed on their PCs in addition to the package they thought they were installing, and thereby earned tens of millions of dollars, but he didn’t want to. The project gets money from donations, but also from companies employing developers to build custom implementations for their set-top boxes.

Why NVidia Really Wants To Buy ARM
by Lawrence D'Oliveiro 13 Feb '21

13 Feb '21

From <https://arstechnica.com/gadgets/2021/02/nvidia-wants-to-buy-cpu-designer-ar…>: Owning Arm outright would also allow Nvidia much greater leeway to innovate upon the design. We've spoken to several vendors who described the sort of innovation that the RISC-V architecture allows as effectively impossible with Arm; the vendors have said "they just won't let you" make changes, like adjustments to the instruction set. If Nvidia owns Arm, it will no longer face such restrictions. And it will be the only company in such a position with respect to ARM. That may make it more competitive with RISC-V, but it will likely just drive other vendors away from ARM ... and towards RISC-V.

Hauwei router source code.
by Ian Stewart 10 Feb '21

10 Feb '21

Hi, I recently searched for the User Manual for a Huawei Model HG253s V2 Home Gateway. I found the document which is dated 2015. Google also found the HG253s V2 open source code.zip file from February 04, 2015 @117MB. Featuring the Linux kernel version 2.6.30 this file was available from huawei.com at... https://consumer-tkb.huawei.com/weknow/servlet/download/public?contextNo=S1… So, based on what I've heard from the CIA, MI6, GCSB and Five-Eyes, I'm now looking through the source code for the functions that send the messages back to the mothership in China 😉 ...Haven't found any code that does this so far ! In summary. I was surprised that Huawei release their source code. Admittedly it's for a device that's at least five years old and, for all I know, it may be the same code that OpenWRT use. I guess I'll still have to wait a while for the source code for the Huawei 5G routers. cheers, Ian.

Most Anti-Zoombombing Measures Are Futile
by Lawrence D'Oliveiro 05 Feb '21

05 Feb '21

How do you keep unwanted busybodies out of your videoconference meetings? This analysis <https://arstechnica.com/information-technology/2021/02/zoombombing-counterm…> concludes that common measures like password-protected meetings and waiting rooms are ineffective because they guard against the wrong threats. One thing that does help is giving each invited participant a unique join link. Ideally this link can only be used once. But even if not, it still allows organizers to identify the source of a leak to a zoombomber.

Firefox 85 Hammers the Final Nail Into the Adobe Flash Coffin
by Peter Reutemann 03 Feb '21

03 Feb '21

'With Mozilla's release of Firefox 85 on Tuesday, Adobe's once ubiquitous Flash technology is really gone for good. The software had been widely used to expand gaming, video and animation on the web, though Adobe stopped supporting it at the end of 2020. Firefox was the last major browser to support Flash. From a report: Apple, whose late boss Steve Jobs helped sink Flash by banning it from iPhones and iPads, ditched Flash with Safari 14 in September 2020. Google Chrome, the most widely used browser, completely excised it on Jan. 19 with version 88. Microsoft's Edge 88 followed suit on Jan. 21. The schedule of removals shows just how hard it is to advance technology foundations as widely used as the web. Browser makers for years wanted to remove Flash, replacing it with more advanced standards built directly into the web. Jobs' "Thoughts on Flash" letter in 2010 solidified the opposition, and Adobe started recognizing the software's doom by scrapping the Android version of Flash in 2011. It's taken years of effort to drop Flash completely. Adobe took until 2017 to announce that Flash would be completely unsupported at the end of 2020, and still some are willing to jump through lots of hoops to keep Flash around a little longer.' -- source: https://it.slashdot.org/story/21/01/26/1618254 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

ActiveX All Over Again?
by Lawrence D'Oliveiro 02 Feb '21

02 Feb '21

Is Google repeating history, by pushing new browser features regardless of their security implications, like Microsoft did in the bad old days? This article <https://www.theregister.com/2021/02/01/chrome_89_beta_brings_desktop/> reports on Chrome adding some new capabilities that other browser developers (like Mozilla and Apple) feel are far too dangerous to allow, at least in their current form. The problem is, will most users fail to appreciate the security issues, see this feature omission as a bug in those browsers, and reinforce the dominance of Chrome as a result?

The End Of Itanium
by Lawrence D'Oliveiro 02 Feb '21

02 Feb '21

The latest Linux kernel will no longer include support for Intel/HP’s Itanium processors <https://www.theregister.com/2021/02/01/linux_pulls_itanium_support/>. Of course, prior Linux kernels up to 5.10 from December presumably still include such support, while the last version of HP’s own HP-UX 11i for its Itanium-based Integrity servers was v3 from 2007 <https://en.wikipedia.org/wiki/HP-UX#Release_history>. The last working version of Microsoft’s Windows Server for that platform, 2008 R2, came out just a couple of years later, and already dropped some features compared to editions for other platforms <https://en.wikipedia.org/wiki/Windows_Server_2008_R2#Editions>. Intel officially claims to be shipping new Itanium processors up to July this year, but it seems pretty clear the order book is empty. So it looks like the last OS still standing for that platform will be Linux.

Google Threatens To Remove Search in Australia as Spat Escalates
by Peter Reutemann 01 Feb '21

01 Feb '21

'Google has threatened to disable its search engine in Australia if it's forced to pay local publishers for news, a dramatic escalation of a months-long standoff with the government. From a report: The proposed law, intended to compensate publishers for the value their stories generate for the company, is "unworkable," Mel Silva, managing director for Australia and New Zealand, told a parliamentary hearing Friday. She specifically opposed the requirement that Google pay media companies for displaying snippets of articles in search results. The threat is Google's most potent yet as the digital giant tries to stem a flow of regulatory action worldwide. At least 94% of online searches in Australia go through the Alphabet unit, according to the local competition regulator. "We don't respond to threats," Australia Prime Minister Scott Morrison said Friday. "Australia makes our rules for things you can do in Australia. That's done in our parliament. It's done by our government.

TinyPilot KVM Over IP
by Lawrence D'Oliveiro 31 Jan '21

31 Jan '21

Just been watching this review <https://www.youtube.com/watch?v=CyEpshm16HY> of the TinyPilot KVM-over-IP box. It’s purchasable from the maker’s website for US$300-plus, which is a fraction of the price of most other KVM-over-IP products. It’s built around a Raspberry π 4, using the camera adapter for HDMI in (no use made of the GPIO connector at all). Of course this means it can only support a connection to a single server machine. The source code is on GitHub if you want to build that yourself. The base product offers insecure HTTP-only access; if you want HTTPS, you have to pay extra for the TinyPilot Pro software licence. For comparison, some reader comments mention an alternative “PiKVM” product -- has anyone heard of this?

CERN Gets Its Open Hardware Licence Approved By OSI
by Lawrence D'Oliveiro 31 Jan '21

31 Jan '21

CERN wanted to come up with the hardware equivalent of open-source software licences. Such licences don’t really work well with hardware, because they use terms (like “linking” and “system libraries”) that aren’t applicable to hardware. So they worked with the Open Source Initiative (the custodians of the Open Source Definition) to come up with a selection of three licences, allowing for a choice of strong copyleft (GPL-equivalent), weak copyleft (LGPL-equivalent, I guess) and no copyleft at all. It seems these licences could actually be used for a combination of both hardware and software. <https://www.theregister.com/2021/01/29/cern_ohl_approved/>

Cloning SSD's
by Ian Stewart 31 Jan '21

31 Jan '21

FWIW: My recent experiences with copying SSD's... I recently installed Ubuntu Mate from USB stick to a 120GB SSD. I then updated with all the latest patches. This took about 30 minutes. I then tailored my preferences of Firefox, Terminal, Pluma, etc. Created a Guest account. Installed the NZ dictionary, and added some applications. This took me another 30 minutes. I then needed to do this to 5 more computers. So, to prepare six computers would have taken me a total of about 6 hours. I considered using the utility "dd" to copy a clone of my master disk. Looking through stackoverflow<https://unix.stackexchange.com/questions/144172/full-dd-copy-from-hdd-to-hdd> I found the suggestion to use "cat". I.e. Boot Ubuntu from a USB stick and assuming sda is my master disk and sdb is the clone, then issue the command... $ sudo sh -c 'cat /dev/sda >/dev/sdb' I found this copying took about 15 minutes. However, it didn't give me any progress report during the copying sequence. I then... $ sudo apt install pv ...pv stands for "Pipe Viewer". For the next SSD drive to be cloned I issued the command... $ sudo sh -c 'pv /dev/sda >/dev/sdb' ...which then provided a progress bar that updated every second. With Samsung SSD 120GB drives I found the operation took 13 minutes 13 seconds with a transfer rate of 153MB/s. I later had built another master SSD on a Kingston 120GB SSD and cloned this to another Kingston 120GB SSD which took 10 minutes and had a transfer rate of 200MB/s. I found with the system still powered on, I could unplug the cloned SSD and plug in another blank SSD and start another cloning. Probably not a recommended practice. After booting the clone, I edited /etc/hostname to make each clone unique. Maybe there's something else I should change??? In summary, allowing for a bit of time to physically move the SSD's between machines, I was effectively completing the installation/updating/tailoring at a rate of three PC's an hour. I dunno if this was the right way or the best way, but, so far, the masters and all the clones seem to be working OK. cheers, Ian.

Intel Iris Xe Video Cards Now Shipping To OEMs: DG1 Lands In Desktops
by Peter Reutemann 29 Jan '21

29 Jan '21

'Ryan Smith, writing at AnandTech: Following plans first unveiled last year during the launch of their DG1 GPU, Intel sends word this morning that the first Iris Xe video cards have finally begun shipping to OEMs. Based on the DG1 discrete GPU that's already being used in Intel's Iris Xe MAX laptop accelerators, the Iris Xe family of video cards are their desktop counterpart, implementing the GPU on a traditional video card. Overall, with specifications almost identical to Xe MAX, Intel is similarly positioning these cards for the entry-level market, where they are being released as an OEM-only part. As a quick refresher, the DG1 GPU is based on the same Xe-LP graphics architecture as Tiger Lake's integrated GPU. In fact, in broad terms the DG1 can be thought of as a nearly 1-to-1 discrete version of that iGPU, containing the same 96 EUs and 128-bit LPDDR4X memory interface as Tiger Lake itself. Consequently, while DG1 is a big first step for Intel -- marking the launch of their first discrete GPU of the modern era -- the company is planning very modestly for this generation of parts. The first DG1 GPUs were shipped in the fall as part of Intel's Iris Xe MAX graphics solution for laptops. At the time, Intel also indicated that a desktop card for OEMs would also be coming in 2021, and now, right on schedule, those desktop cards have begun shipping out.' -- source: https://hardware.slashdot.org/story/21/01/28/1649204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

ProtonMail, Threema, Tresorit and Tutanota Warn EU Lawmakers Over 'Anti-Encryption' Push
by Peter Reutemann 29 Jan '21

29 Jan '21

'Four European apps which secure user data via end-to-end encryption, ProtonMail, Threema, Tresorit and Tutanota, have issued a joint-statement warning over recent moves by EU institutions that they say are setting lawmakers on a dangerous path to backdooring encryption. From a report: Last month the EU Council passed a resolution on encryption that's riven with contradiction -- calling for "security through encryption and security despite encryption" -- which the four e2e app makers believe is a thinly veiled call to backdoor encryption. The European Commission has also talked about seeking "improved access" to encrypted information, writing in a wide-ranging counter-terrorism agenda also published in December that it will "work with Member States to identify possible legal, operational, and technical solutions for lawful access." Simultaneously, the Commission has said it will "promote an approach which both maintains the effectiveness of encryption in protecting privacy and security of communications, while providing an effective response to crime and terrorism." And it has made it clear there will be no 'one silver bullet' as regards the e2e encryption security 'challenge.' But such caveats are doing nothing to alleviate the concerns of e2e encrypted app makers -- who are convinced proposals from the Council of the EU, which is involved in adopting the bloc's laws (though the Commission usually drafts legislation), sums to an push toward backdoors. "While it's not explicitly stated in the resolution, it's widely understood that the proposal seeks to allow law enforcement access to encrypted platforms via backdoors," the four app makers write, going on to warn that such a move would fatally underline the security EU institutions also claim to want to maintain. "The resolution makes a fundamental misunderstanding: Encryption is an absolute, data is either encrypted or it isn't, users have privacy or they don't," they go on. "The desire to give law enforcement more tools to fight crime is obviously understandable. But the proposals are the digital equivalent of giving law enforcement a key to every citizen's home and might begin a slippery slope towards greater violations of personal privacy."' -- source: https://yro.slashdot.org/story/21/01/28/1724250 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Rocky Linux gets a parent company, with $4m Series A funding
by Peter Reutemann 29 Jan '21

29 Jan '21

'Gregory Kurtzer, co-founder of the now-defunct CentOS Linux distribution, has founded a new startup company called Ctrl IQ, which will serve in part as a sponsoring company for the upcoming Rocky Linux distribution. Rocky Linux is to be a beneficiary of Ctrl IQ's revenue, not its source—the company describes itself in its announcement as the suppliers of a "full technology stack integrating key capabilities of enterprise, hyper-scale, cloud and high-performance computing."' -- source: https://arstechnica.com/gadgets/2021/01/rocky-linux-gets-a-parent-company-w… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

GitLab Reshuffles Its Paid Subscription Plans, Drops Its Bronze/Starter Tier
by Peter Reutemann 28 Jan '21

28 Jan '21

'GitLab, the increasingly popular DevOps platform, today announced a major update to its subscription model. The company is doing away with its $4/month Bronze/Starter package. Current users will be able to renew one more time at the existing price or move to a higher tier (and receive a significant discount for the first three years after they do so). The company's free tier, it is worth noting, is not going away and GitLab argues that it includes "89% of the features in Bronze/Starter." To ease the pain, Bronze users will be able to renew their existing subscription before January 26, 2022 for an additional year at the existing price. They can also opt to move to the Premium tier at a discounted price for the next three years, starting at $6/user/month in Year 1, but that price then goes up to $9/user/month and $15/user/month in Year 2 and 3 respectively. For new users, the Bronze package is no longer available, starting now. With this change, GitLab now offers three tiers: Free, Premium and Ultimate (it's also doing away with the "Silver/Premium" and "Gold/Ultimate" naming). "The Bronze tier, we were selling at a loss," GitLab founder and CEO Sid Sijbrandij told TechCrunch. "We were just losing money every time we sold it -- just on hosting and support. To be a sustainable business, this was a move we had to make. It's a big transition for our customers but we want to make sure we're a sustainable company and we can keep investing."' -- source: https://tech.slashdot.org/story/21/01/27/215226 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Reddit 1: Wall Street 0
by Lawrence D'Oliveiro 28 Jan '21

28 Jan '21

Something very peculiar happened last week: a group of small-time stock traders who hang out on Reddit took on a well-funded Wall Street money manager, and won. What happened was, a company called Melvin Capital took out a “short position” on shares in GameStop--that is, they put money on a bet that the stock value would go down. The Redditors (part of a subreddit called “wallstreetbets”) figured out that this position was vulnerable, and bet against it by buying up GameStop shares. This drove up the price, forcing Melvin to either put up or shut up--put up a bunch of money to back up their position, or give up and lose an even bigger bunch of money. In other words, Melvin was caught in a “short squeeze”, which drove it to the verge of bankruptcy. A good, clear intro to the whole story is here <https://arstechnica.com/gaming/2021/01/the-complete-morons-guide-to-gamesto…>. A less-easy-to-understand analysis, with links to further articles, is here <https://www.aljazeera.com/economy/2021/1/27/bbgamestop-how-day-trader-reddi…>.

10-year-old Sudo Bug Lets Linux Users Gain Root-Level Access
by Peter Reutemann 28 Jan '21

28 Jan '21

'A major vulnerability impacting a large chunk of the Linux ecosystem has been patched today in Sudo, an app that allows admins to delegate limited root access to other users. From a report: The vulnerability, which received a CVE identifier of CVE-2021-3156, but is more commonly known as "Baron Samedit," was discovered by security auditing firm Qualys two weeks ago and was patched earlier today with the release of Sudo v1.9.5p2. In a simple explanation provided by the Sudo team today, the Baron Samedit bug can be exploited by an attacker who has gained access to a low-privileged account to gain root access, even if the account isn't listed in /etc/sudoers -- a config file that controls which users are allowed access to su or sudo commands in the first place.' -- source: https://linux.slashdot.org/story/21/01/27/1820205 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Play Bans Video App For Standard “.ass” Subtitle Support
by Lawrence D'Oliveiro 27 Jan '21

27 Jan '21

libass <https://github.com/libass/libass> is an open-source library for decoding the .ass/.ssa subtitle formats for video files. However, the automated censor-bot in the Google Play Store decided that an app supporting this format was violating the “Sexual Content and Profanity Policy”, and suspended it. The app was only reinstated after an appeal. <https://arstechnica.com/gadgets/2021/01/googles-bots-decide-ass-subtitle-su…>

Browser Makers Launch New Project For Writing Documentation For Web APIs
by Peter Reutemann 26 Jan '21

26 Jan '21

'A coalition of tech companies announced today the launch of Open Web Docs, a new initiative to help write documentation for Web APIs, JavaScript, and other web tooling and platforms. From a report: The new project does not view itself as a replacement for MDN Web Docs, a website hosted by Mozilla, where all browser makers agreed to move the official Web API documentation back in October 2017, and stop developing their own, often diverging, documentation sites. Instead, in a press release and FAQ today, the Open Web Docs team said their role is to fund, coordinate, and contribute to MDN Docs going forward. The new initiative comes after Mozilla laid off 250 employees last summer, including many of its MDN Web Docs staff. Open Web Docs comes to fill this void and provide the labor force needed to continue updating the MDN Web Docs portal.' -- source: https://tech.slashdot.org/story/21/01/25/216208 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 577-5304 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Hacker Leaks Data of 2.28 Million Dating Site Users
by Peter Reutemann 26 Jan '21

26 Jan '21

'ZDNet: A well-known hacker has leaked the details of more than 2.28 million users registered on MeetMindful.com, a dating website founded in 2014, ZDNet has learned this week from a security researcher. The dating site's data has been shared as a free download on a publicly accessible hacking forum known for its trade in hacked databases. The leaked data, a 1.2 GB file, appears to be a dump of the site's users database. The content of this file includes a wealth of information that users provided when they set up profiles on the MeetMindful site and mobile apps. Some of the most sensitive data points included in the file include: Real names; Email addresses; City, state, and ZIP details; Body details; Dating preferences; Marital status; Birth dates; Latitude and longitude; IP addresses; Bcrypt-hashed account passwords; Facebook user IDs; and Facebook authentication tokens. Messages exchanged by users were not included in the leaked file; however, this does not make the entire incident less sensitive. The data leak, which is still available for download, was released by a threat actor who goes by the name of ShinyHunters. They also were responsible for leaking the details of millions of users registered on Teespring.

Fedora’s Chromium Maintainer Suggests Switching To Firefox
by Lawrence D'Oliveiro 26 Jan '21

26 Jan '21

Google is withdrawing access to certain of its service APIs that were formerly available to open-source Chromium builds, reserving them for its own proprietary Chrome product. In response, the maintainer for Fedora’s Chromium package says he is no longer sure of the value of Chromium, and is recommending users switch to Firefox instead. But then again, some are seeing the removal of Google APIs as an improvement. <https://www.theregister.com/2021/01/25/use_firefox_fedora_chromium_maintain…>
