by Peter Reutemann 04 Feb '22

04 Feb '22

'System76's latest Linux laptop combines one of AMD's most powerful 5000 series mobile CPUs with Nvidia's mid-range RTX 3060. Configurable to up to $3,442, the Kudu targets Linux users who have a lot of work to do, while quietly nodding at those who like to play games every now and then, too. The 15.6-inch Kudu is the second-priciest offering in System76's laptop lineup. It comes with an octa-core AMD Ryzen 9 5900HX, which has a base clock speed of 3.3 GHz and a boost of up to 4.6 GHz.' -- source: https://arstechnica.com/gadgets/2022/02/system76-linux-laptop-unites-amd-nv… 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/

Mozilla is Shutting Down Its VR Web Browser, Firefox Reality
by Peter Reutemann 04 Feb '22

04 Feb '22

'A top VR web browser is closing down. Today, Mozilla announced it's shutting down its Firefox Reality browser -- the four-year-old browser built for use in virtual reality environments. The technology had allowed users to access the web from within their VR headset, doing things like visiting URLs, performing searches, and browsing both the 2D and 3D internet using your VR hand controllers, instead of a mouse. >From a report: Firefox Reality first launched in fall 2018 and has been available on Viveport, Oculus, Pico, and Hololens platforms through their various app stores. While capable of surfing the 2D web, the expectation was that users would largely use the new technology to browse and interact with the web's 3D content, like 360-degree panoramic images and videos, 3D models, and WebVR games, for example. But in an announcement published today, Mozilla says the browser will be removed from the stores where it's been available for download in the "coming weeks." Mozilla is instead directing users who still want to utilize a web browser in VR to Igalia's upcoming open-source browser, Wolvic, which is based on Firefox Reality's source code. This browser will be available for download starting next week, so users won't have to go without -- they'll just have to make the switch.' -- source: https://tech.slashdot.org/story/22/02/03/1653218 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/

Slackware, the Oldest Actively Maintained Linux Distro, Releases Version 15.0
by Peter Reutemann 04 Feb '22

04 Feb '22

'Slackware, the oldest actively maintained Linux distribution, released version 15.0 yesterday after a long release cycle that goes all the way back to 2016 where the last version (14.2) was released. According to the release notes, the whole spirit of this release is: "Keep it familiar, but make it modern." Among the news, this release offers kernel 5.15.19, PAM, PipeWire and PulseAudio, Wayland and X11 graphical systems, and Rust and Python 3. As graphical environments, both Xfce 4.16 and the latest Plasma 5 (Plasma 5.23.5, Frameworks 5.90, KDE apps 21.12 running under Qt 5.15.3) are available, with Cinnamon and Mate also available from third parties. The main compilers are gcc-11.2 and llvm 13.0. The default browser is Firefox 91.5esr, with Chromium available as a third-party repository. And... no systemd at all. Slackware can be downloaded from a variety of mirrors. BitTorrent downloads are going to be available too. I've used Slackware for 20 years and it's always impressed me with its stability and speed. I encourage everyone interested to try it.' -- source: https://linux.slashdot.org/story/22/02/04/027213 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/

Microsoft Says Windows May Need Up To 8 Hours of Online Time To Update
by Peter Reutemann 03 Feb '22

03 Feb '22

'According to a post on the Microsoft IT Pro Blog, Windows computers will need at least eight hours of online time to obtain and install the latest OS updates successfully. Tom's Hardware reports: Another revelation in the post is that Microsoft tracks how long PCs are connected to Windows Update, calling the statistics "Update Connectivity." The data is available to IT managers in the InTune app, a component of the Endpoint management suite. The post details Microsoft's attempts to figure out why some Windows devices aren't getting the latest quality and feature updates, and discovered that two hours of continuous connectivity was required to get updates. It then took six hours after the release of the patch for a machine to update itself reliably. Microsoft's figures show that 50 percent of Windows devices left behind by Windows Update and running a build of Windows 10 that's no longer serviced do not spend enough time connected to have the patches downloaded and installed in the background. This figure drops to 25 percent for customers using a serviced build of the operating system that lags behind in security updates by 60 days or more. The goods news, as noted by Tom's Hardware, is that "Windows 11 updates are smaller than their Windows 10 counterparts due to improved compression [and] new Microsoft Graph APIs," which should help speed up the update process.' -- source: https://tech.slashdot.org/story/22/02/01/2056211 Bloatware? I can download/install full Linux distros in less time (and updates don't take that long either, not even a full version upgrade!).

Insights Into WSL 1.0
by Lawrence D'Oliveiro 03 Feb '22

03 Feb '22

You may remember that Microsoft’s initial attempt at “Windows Services for Linux”, WSL 1.0 (or maybe just plain “WSL”), involved emulating Linux APIs on top of the Windows kernel. This was later scrapped in favour of the current WSL 2.0, which runs an actual Linux kernel, virtualized. Clearly, Microsoft found it problematic trying to keep things compatible with the native Linux kernel, and decided it was simpler to just run the real article. This report <https://www.theregister.com/2022/02/02/oracle_linux_microsoft/> links in passing to an interesting blog post <https://jmmv.dev/2020/11/wsl-lost-potential.html> covering some of the technicalities of how WSL 1.0 was implemented. Windows NT has, or had, the notion of different “environment subsystems” or “personalities” implemented in layers on top of the core kernel; in fact, Win32 is (or was) just one of these “personalities”, with the original POSIX layer being another. That blog post says that WSL1 was implemented as just such a “personality”. And if that had not been scrapped, it would have made some interesting kinds of integration across Windows and Linux processes possible. However, a reader comment to the original article <https://forums.theregister.com/forum/all/2022/02/02/oracle_linux_microsoft/…>, claiming to come from a former “PM” (“Product Manager”?) for WSL, emphatically declares ... WSL is not an NT kernel "personality" and is in no way related to NT's POSIX subsystem. Not even slightly. They are entirely different implementations of different things and share zero architecture and implementation details. This reinforces an impression I’ve had, that much of the modularity of the original Windows NT architecture has decayed away over the years, sacrificed by Microsoft to marketing exigencies. And that includes the whole “environment subsystem” concept. So WSL1 was actually less modular than it might have appeared to begin with, and that would have added to the support headaches.

64-bit Raspberry Pi OS exits beta, is available for all Pi 3, 4, and Zero 2 boards
by Peter Reutemann 03 Feb '22

03 Feb '22

'The Raspberry Pi hardware has included a 64-bit processor since the Pi 3 launched in early 2016, but the Raspberry Pi OS (formerly known as Raspbian) has remained primarily 32-bit. The Raspberry Pi Foundation has been testing a 64-bit version of the OS since 2020, though, and today the organization announced that the 64-bit version is leaving beta and is now a fully supported OS option on all 64-bit Pi hardware. This includes the Pi 3, Pi 4, Pi Zero 2 W, and all variants thereof.' -- source: https://arstechnica.com/gadgets/2022/02/64-bit-raspberry-pi-os-exits-beta-i… 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/

Backblaze Hard Drive Reliability Stats For 2021
by Lawrence D'Oliveiro 02 Feb '22

02 Feb '22

Data-backup company Backblaze has released its annual report on hard-drive reliability for 2021 <https://www.theregister.com/2022/02/01/backblaze_hd_reliability_stats_show/>. Interesting that there is an overall longer-term downward trend in drive failures, though this can fluctuate some. The company is in a good position to compare different brands and models, since they tend to shop around a lot (look at that list). Their whole system is designed to cope with drive failures, and given how many drives they have, they get a lot of failures. So there is plenty of raw data available to analyze, which they make freely available.

Remembering Windows Vista
by Lawrence D'Oliveiro 02 Feb '22

02 Feb '22

Here is a look back <https://www.theregister.com/2022/02/01/happy_birthday_windows_vista/> at the troubled gestation of Windows Vista. It’s useful as a retrospective, full of links to reports on developments from that time. One of the article links is to this analysis <https://www.theregister.com/2001/08/07/ms_poised_to_switch_windows/> of where Microsoft was supposedly going at the time. (Re)reading that is like peering through a portal into an alien, forgotten world -- one where the company was full of grandiose plans for building an entire OS on Dotnet, making your Exchange mail folders look like a filesystem volume, tying the representation of Office documents to proprietary features of NTFS, and turning the filesystem itself into a database. And one where users and pundits took such plans seriously.

German Court Fines Company For Linking To Google-Hosted Web Font
by Lawrence D'Oliveiro 01 Feb '22

01 Feb '22

Seems lots of websites link to web fonts hosted by Google. But do they realize this means that users of their sites are sending their IP addresses to Google’s servers? And that not getting the consent of your users to such a thing can land you in legal trouble, at least in the EU? <https://www.theregister.com/2022/01/31/website_fine_google_fonts_gdpr/> I don’t know why people do this anyway -- depending on another site just introduces an additional potential point of failure to your site. Fonts are not that big‡: how great a hardship would it be to copy them to your own site, and link to them there? ‡Had a quick check of my /usr/share/fonts/truetype/noto/ directory, which contains an installation of Google’s entire Unicode-friendly “Noto” font collection; that’s got 2380 entries totalling not quite half a gigabyte.
