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.
