Weta Digital’s Technology Division Sold To US Firm
by Lawrence D'Oliveiro 01 Aug '25

01 Aug '25

Let me see if I understand this article <https://www.nzherald.co.nz/business/sir-peter-jackson-to-sell-weta-digital-…> correctly: the part of Weta Digital that used to develop the in-house 3D graphics/effects tools that they use in all those movies is being sold to US-based Unity Software. The part that is left will be called “WetaFX”, and will become a customer of Unity for the use of those tools, no longer doing its own development in-house. By the way, I’ve been looking at the Unity site <https://unity.com/>, and it looks like all their products are rentware (subscription-based).

List Of IPTV Resources
by Lawrence D'Oliveiro 22 Sep '24

22 Sep '24

This user <https://github.com/iptv-org> just popped up in my GitHub feed. One repo <https://github.com/iptv-org/iptv> claims to be a list of links to over 8000 streaming TV channels from nations all over the world, while the other is a list of tools*, providers and other resources. Do be aware it’s a bit of a mixed bag: yes, there are legitimate channels (no encryption so far that I have noticed), but also some dubious-looking links. *Oddly, FFmpeg and youtube-dl aren’t in the list.

Enabling Case-Insensitive Filenames On Linux
by Lawrence D'Oliveiro 06 Feb '24

06 Feb '24

The ext4 filesystem has had the “casefold” option for a while now <https://lwn.net/Articles/784041/>. This allows you to specify, when you initialize a new filesystem, that you want file/directory names to be treated as case-insensitive. At the same time, you have to specify that the filenames are to be interpreted as UTF-8 encoding; normally the kernel doesn’t care, it only singles out ASCII slash and NUL bytes for special interpretation, and simply passes through any other byte values in the names. I was able to create such a filesystem, but I wasn’t able to mount it in my last-upgraded-just-a-few-days-ago Debian Unstable setup. When I try, it fails, and in the dmesg log I see Filesystem with casefold feature cannot be mounted without CONFIG_UNICODE Turns out the Debian 5.10 kernel has not been built with this CONFIG_UNICODE option enabled. However, this situation looks set to change shortly, according to <https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=985689>.

ReiserFS is now “obsolete” in the Linux kernel and should be gone by 2025
by Peter Reutemann 01 Sep '23

01 Sep '23

'When Apple was about to introduce Time Machine in Mac OS X Leopard, John Siracusa wrote in the summer of 2006 about how a new file system should be coming to Macs (which it did, 11 years later). The Mac, Siracusa wrote, needed something that could efficiently handle lots of tiny files, volume management with pooled storage, checksum-based data integrity, and snapshots. It needed something like ZFS or, perhaps, ReiserFS, file systems “notable for their willingness to reconsider past assumptions about file system design.” Two months later, the name Reiser would lose most of its prestige and pick up a tragic association it would never shake. Police arrested the file system’s namesake, Hans Reiser, and charged him with murder in connection with the disappearance of his estranged wife. Reiser’s work on Linux file systems was essentially sentenced to obscurity from that point on. Now that designation has been made official, as the file system that was once the default on systems like SUSE Linux has been changed from “Supported” to “Obsolete” in the latest Linux 6.6 kernel merge process (as reported by Phoronix). While a former employee of Reiser’s company, Namesys, continues out-of-source work on later versions of ReiserFS, it is likely to disappear from the kernel entirely in a matter of years, likely 2025. It's an ignoble end for a filesystem that, at one time, could have been the next big thing for Linux file systems.' -- source: https://arstechnica.com/gadgets/2023/08/the-torrid-saga-of-reiserfs-nears-i… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Google Removes Fake Signal and Telegram Apps Hosted on Play
by Peter Reutemann 01 Sep '23

01 Sep '23

'Researchers say they have found fake apps in Google Play that masqueraded as legitimate ones for the Signal and Telegram messaging platforms. The malicious apps could pull messages or other sensitive information from legitimate accounts when users took certain actions. ArsTechnica: An app with the name Signal Plus Messenger was available on Play for nine months and had been downloaded from Play roughly 100 times before Google took it down last April after being tipped off by security firm ESET. It was also available in the Samsung app store and on signalplus[.]org, a dedicated website mimicking the official Signal.org. An app calling itself FlyGram, meanwhile, was created by the same threat actor and was available through the same three channels. Google removed it from Play in 2021. Both apps remain available in the Samsung store. Both apps were built on open source code available from Signal and Telegram. Interwoven into that code was an espionage tool tracked as BadBazaar. The Trojan has been linked to a China-aligned hacking group tracked as GREF. BadBazaar has been used previously to target Uyghurs and other Turkic ethnic minorities. The FlyGram malware was also shared in a Uyghur Telegram group, further aligning it to previous targeting by the BadBazaar malware family. Signal Plus could monitor sent and received messages and contacts if people connected their infected device to their legitimate Signal number, as is normal when someone first installs Signal on their device. Doing so caused the malicious app to send a host of private information to the attacker, including the device IMEI number, phone number, MAC address, operator details, location data, Wi-Fi information, emails for Google accounts, contact list, and a PIN used to transfer texts in the event one was set up by the user.' -- source: https://tech.slashdot.org/story/23/08/31/1655233 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

With Version 117, Firefox Finally Speaks Chrome's Translation Language
by Peter Reutemann 01 Sep '23

01 Sep '23

'The latest version of the flagship FOSS browser is out, and it's picked up one of the main features for which we keep Chrome around. >From a report: The Firefox version 117 feature list might not look all that impressive, but it does have a big-ticket feature that may tempt people back: automatic translation. The snag is it's disabled by default in the release version, and you'll have to manually enable it. Although it was enabled in the betas, Mozilla has decided to go for a staged rollout and not enable it for everyone until Firefox 118 in six weeks or so. The new feature is integrated, privacy-respecting machine translation between multiple languages. This was already possible in older versions, but it needed an extension, and that had two side effects. One is that the extension hooked deep into the core of the browser in ways that Mozilla wasn't comfortable about, and the other is that once your text had been sent out to a third-party website, it could be snooped upon -- but the victims of any snooping would blame the browser, even if it wasn't the browser's fault. To enable it, go to the configuration page (enter about:config in the address bar), and search for a setting called browser.translations.enable.' -- source: https://tech.slashdot.org/story/23/08/31/1658259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

FreeBSD Can Now Boot in 25 Milliseconds
by Peter Reutemann 31 Aug '23

31 Aug '23

'Replacing a sort algorithm in the FreeBSD kernel has improved its boot speed by a factor of 100 or more... and although it's aimed at a micro-VM, the gains should benefit everyone. From a report: MicroVMs are a hot area of technology R&D in the last half decade or so. The core idea is a re-invention of some of concepts and technology that IBM invented along with the hypervisor in the 1960s: designing OSes specifically to run as guests under another OS. This means building the OS specifically to run inside a VM, and to talk to resources provided by a specific hypervisor rather than to fake hardware. This means that the guest OS needs next to no support for real hardware, just VirtIO drivers which talk directly to facilities provided by the host hypervisor. In turn, the hypervisor doesn't have to provide an emulated PCI bus, emulated power management, emulated graphics card, emulated network interface cards, and so on. The result is that the hypervisor itself can be much smaller and simpler. The result of ruthlessly chopping down both the hypervisor, and the OS that runs inside it, is that both ends can be much smaller and simpler. That means that VMs can use much fewer resources, and start up much quicker.' -- source: https://tech.slashdot.org/story/23/08/30/1525238 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Nautilus File Manager Gets New Features in Upcoming GNOME 45
by Peter Reutemann 29 Aug '23

29 Aug '23

'The upcoming release of GNOME 45 — expected September 20th — will bring new features to the Nautilus file manager (now in public beta testing). An anonymous reader shared this report from 9to5Linux: Nautilus in GNOME 45 already received a search performance boost, support for dropping images directly from web pages, an improved Grid View that now indicates starred files too, the ability to display bytes size as a tooltip for folder properties, and a more adaptive design for the sidebar. It also got an improved file opening experience while sandboxed (think Flatpak, Snap, etc.), a more consistent date and time format, a more simplistic definition of the Keyboard Shortcuts window, the ability to refocus the search bar using the Ctrl+F keyboard shortcut, and a better archiving experience. But there's room for more new features as Nautilus now received new "Search Everywhere" buttons to expand the search scope and a modern full-height sidebar layout, along with refined sidebar sizing and folding threshold. This is what Nautilus looks like in GNOME 45. The article includes some screenshots, adding that Nautilus "also received some performance improvements to more quickly generate multiple thumbnails, provide users with flickerless transition into and from search, and avoid DBus-activating other apps when it starts."' -- source: https://linux.slashdot.org/story/23/08/27/2329227 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Linux What's New in Linux 6.5?
by Peter Reutemann 28 Aug '23

28 Aug '23

'9to5Linux: Just a couple of days after celebrating its 32nd anniversary , Linus Torvalds announced today the final release of the Linux 6.5 kernel series as a major update that introduces several new features, updated and new drivers for better hardware support, and other changes. After seven weeks of RCs, Linux kernel 6.5 is here with new features like MIDI 2.0 support in ALSA, ACPI support for the RISC-V architecture, Landlock support for UML (User-Mode Linux), better support for AMD "Zen" systems, as well as user-space support for the ARMv8.8 memcpy/memset instructions. Also new in Linux 6.5 is Intel TPMI (Topology Aware Register and PM Capsule Interface) support for the power capping subsystem and a TPMI interface driver for Intel RAPL, and the "runnable boosting" feature in the EAS balancer to improve CPU utilization for specific workloads. This release also improves SMP scheduling's load balancer to recognize SMT cores with more than one busy sibling and allows lower-priority CPUs to pull tasks to avoid superfluous migrations, and improves EXT4 file system's journalling, block allocator subsystems, and performance for parallel DIO overwrites.' -- source: https://linux.slashdot.org/story/23/08/27/2316212 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Can You Run Linux On a Commodore 64?
by Peter Reutemann 28 Aug '23

28 Aug '23

'llvm-mos adapts the popular LLVM compiler to target the MOS 6502 processor (the 1980s microprocessor used in early home computing devices like the Apple II and the Commodore 64). So developer Onno Kortman used it to cross-compile semu, a "minimalist RISC-V system emulator capable of running Linux the kernel and corresponding userland." And by the end of the day, Kortman has Linux running on a Commodore 64. Long-time Slashdot reader johnwbyrd shared the link to Kortman's repository. Some quotes: "But does it run Linux?" can now be finally and affirmatively answered for the Commodore C64...! It runs extremely slowly and it needs a RAM Expansion Unit (REU), as there is no chance to fit it all into just 64KiB. It even emulates virtual memory with an MMU.... The screenshots took VICE a couple hours in "warp mode" (activate it with Alt-W) to generate. So, as is, a real C64 should be able to boot Linux within a week or so. The compiled 6502 code is not really optimized yet, and it might be realistic to squeeze a factor 10x of performance out of this. Maybe even a simple form of JIT compilation? It should also be possible to implement starting a checkpointed VM (quickly precomputed on x86-64) to avoid the lengthy boot process... I also tested a minimal micropython port (I can clean it up and post it on github if there is interest), that one does not use the MMU and is almost barely remotely usable with lots of optimism at 100% speed. A key passage: I have not tested it on real hardware yet, that's the next challenge .. for you. So please send me a link to a timelapse video of an original unit with REU booting Linux :D Its GitHub repository has build and run instructions...' -- source: https://linux.slashdot.org/story/23/08/27/1532207 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

When A Certificate Authority Is Too Big To Fail
by Lawrence D'Oliveiro 26 Aug '23

26 Aug '23

Certificate authorities (CAs) have a crucial role in the chain of trust that binds the computing world together right now. So when it turns out that a rather large company (Symantec) has been issuing dodgy certificates for many years, the ramifications run uncomfortably wide. Google has been gradually winding down its trust of Symantec-issued over a multiyear period, because blocking them all at once would just be too painful for its users. It turns out some of these CAs are also used for signing applications for Windows. Microsoft finally got around to blocking the Symantec one within the last few days, only to abruptly reverse course and trust it again, because it caused serious trouble for too many Windows systems <https://arstechnica.com/security/2023/08/a-renegade-certificate-is-removed-…>. The applications concerned should have been updated to not depend on such a worthless CA. But it seems, ensuring Windows users update all their relevant apps can be a mountain just too high to climb.

Firefox Users May Import Chrome Extensions Now
by Peter Reutemann 25 Aug '23

25 Aug '23

'Mozilla has implemented the WebExtensions system in its browser, allowing Firefox users to import select extensions from other browsers like Chrome. gHacks reports: The feature, which is in testing at the moment, can be enabled by all users of the latest stable version of Firefox. 1. Load about:config in the browser's address bar. 2. Confirm that you will be careful to continue. 3. Search for browser.migrate.chrome.extensions.enabled. 4. Set the feature to True, which enables it. 5. Restart Firefox. Mozilla has integrated it into the browser's import functionality, which users may use on first run or at any time from the Settings page. To do so, select Menu > Settings > Import Data (button), or load about:preferences#general in the browser's address bar and activate the import data button on the page. Select Chrome from the list, expand the available import options and make sure extensions are checked. Imports are usually limited to some data, such as bookmarks or the browsing history. Firefox is the first major browser, maybe the first browser at all, that adds extensions to the list of supported imports. The feature is limited at the time to Google Chrome and select extensions. Even though Firefox and Chrome extensions use the same framework, WebExtensions, they are not compatible immediately. Firefox users who attempt to install extensions from Chrome's Web Store may notice that this is not working. Mozilla decided to create a list of extension pairs for extensions that are available on the Chrome Web Store and the Mozilla Add-ons Store. Instead of importing the Chrome extension directly, Firefox is installing the Firefox version of the extension from Mozilla's own extension store.

WinRAR Flaw Lets Hackers Run Programs When You Open RAR Archives
by Peter Reutemann 23 Aug '23

23 Aug '23

'A critical vulnerability (CVE-2023-40477) has been patched in WinRAR, enabling remote attackers to execute arbitrary code by luring victims into opening a specially crafted RAR file. The severity rating is only 7.8 though due to user deception being necessary. BleepingComputer reports: The vulnerability was discovered by researcher "goodbyeselene" of Zero Day Initiative, who reported the flaw to the vendor, RARLAB, on June 8th, 2023. "The specific flaw exists within the processing of recovery volumes," reads the security advisory released on ZDI's site. "The issue results from the lack of proper validation of user-supplied data, which can result in a memory access past the end of an allocated buffer." RARLAB released WinRAR version 6.23 on August 2nd, 2023, effectively addressing CVE-2023-40477. Therefore, WinRAR users are strongly advised to apply the available security update immediately. Apart from the RAR4 recovery volumes processing code fix, version 6.23 addresses an issue with specially crafted archives leading to wrong file initiation, which is also considered a high-severity problem.' -- source: https://it.slashdot.org/story/23/08/18/2157249 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Latest Android Runtime (ART) Update Led To Apps Starting 30% Faster
by Peter Reutemann 22 Aug '23

22 Aug '23

'The latest update to the Android Runtime (ART) -- the "engine behind the Android operating system (OS)" -- has resulted in app startup time "improvements of up to 30% on some devices," says Google. 9to5Google reports: Behind the scenes, "ART is the same for all devices" and: "The ART APEX module is a complex piece of software with an order of magnitude more APIs than any other APEX module. It also backs a quarter of the developer APIs available in the Android SDK. In addition, ART has a compiler that aims to make the most of the underlying hardware by generating chipset-specific instructions, such as Arm SVE." The testing process for Android Runtime updates involves "compiling over 18 million APKs and running app compatibility tests, and startup, performance, and memory benchmarks on a variety of Android devices that replicate the diversity of our ecosystem as closely as possible." There's then a very gradual rollout process. Google also notes developer improvements with every update "like OpenJDK improvements and compiler optimizations that benefit both Java and Kotlin," with ART 13 resulting in the "fastest-ever adoption of a new OpenJDK [11] release on Android devices." ART 14 is rolling out "in the coming months" with "new compiler and runtime optimizations that improve performance while reducing code size," as well as OpenJDK 17.' -- source: https://slashdot.org/story/23/08/21/212202 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

AlmaLinux Leader Says Red Hat's Code Crackdown Isn't a Threat
by Peter Reutemann 21 Aug '23

21 Aug '23

'Yes, Red Hat Enterprise Linux changed its licensing last month — but how will that affect AlmaLinux? The chair of the nonprofit AlmaLinux OS Foundation, benny Vasquez, tells SiliconANGLE that "For typical users, there's very, very little difference. Overall, we're still exactly the same way we were, except for kernel updates." Updates may no longer be available the day a new version of RHEL comes out, but developers still have access to Red Hat's planned enhancements and bug fixes via CentOS Stream, a version of RHEL that Red Hat uses as essentially a test bed for new features that might later be incorporated into its flagship product. From a practical perspective, that's nearly as good as having access to the production source code, Vasquez said. "While there is a generally accepted understanding that not everything in CentOS Stream will end up in RHEL, that's not how it works in practice," she said. "I can't think of anything they have shipped in RHEL that wasn't in Stream first." That's still no guarantee, but the workarounds AlmaLinux has put in place over the past month should address all but the most outlier cases, Vasquez said. The strategy has shifted from bug-for-bug compatibility to being application binary interface-compatible... ABI compatibility doesn't guarantee that problems will never occur, but glitches should be rare and can usually be resolved by recompiling the source code. "It is sufficient for us to be ABI-compatible with RHEL," Vasquez said. "The most important thing is that this allows our community to feel stability." In fact, Red Hat's change of direction has been a blessing in disguise for AlmaLinux, she said... "We view this as a release from our bonds of being one-to-one." Patches can be applied without waiting for a cue from Red Hat and "we get to engage with our community in a completely new and exciting way." AlmaLinux has also seen a modest financial windfall from Red Hat's decision. "The outpouring of support has been pretty impressive," Vasquez said. "People have shown up for event staffing and website maintenance and infrastructure management and we've gotten more financial backing from corporations." Vasquez also told the site that "the number of everyday people throwing in $5 has more than quadrupled."' -- source: https://linux.slashdot.org/story/23/08/20/0247259 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Debian Turns 30
by Peter Reutemann 18 Aug '23

18 Aug '23

'Debian blog: Over 30 years ago the late Ian Murdock wrote to the comp.os.linux.development newsgroup about the completion of a brand-new Linux release which he named "The Debian Linux Release." He built the release by hand, from scratch, so to speak. Ian laid out guidelines for how this new release would work, what approach the release would take regarding its size, manner of upgrades, installation procedures; and with great care of consideration for users without Internet connection. Unaware that he had sparked a movement in the fledgling F/OSS community, Ian worked on and continued to work on Debian. The release, now aided by volunteers from the newsgroup and around the world, grew and continues to grow as one of the largest and oldest FREE operating systems that still exist today. Debian at its core is comprised of Users, Contributors, Developers, and Sponsors, but most importantly, People. Ians drive and focus remains embedded in the core of Debian, it remains in all of our work, it remains in the minds and hands of the users of The Universal Operating System. The Debian Project is proud and happy to share our anniversary not exclusively unto ourselves, instead we share this moment with everyone, as we come together in celebration of a resounding community that works together, effects change, and continues to make a difference, not just in our work but around the world. Debian is present in cluster systems, datacenters, desktop computers, embedded systems, IoT devices, laptops, servers, it may possibly be powering the web server and device you are reading this article on, and it can also be found in Spacecraft.' -- source: https://linux.slashdot.org/story/23/08/17/136231 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Farewell, Type-1 Fonts
by Lawrence D'Oliveiro 17 Aug '23

17 Aug '23

Following the lead of other vendors, now Adobe itself is abandoning support for the venerable “Type 1” font format that it created <https://arstechnica.com/gadgets/2023/08/microsoft-adobe-and-others-have-dro…>. Back in the days when PostScript printers were new and wonderful things, the PostScript language was an open, published spec, but the high-quality font format that Adobe’s printers used was not. This format included a “secret sauce” in the form of “hints” to the rasterizer that smoothed out irregularities. Because if you took letter shapes expressed as scalable vector graphics and tried rendering them in a straight geometric fashion at typical text sizes on a black-and-white output device, even at as high as 300 dpi, there would be a noticeable roughness to the shapes. Nowadays the techniques for applying such hinting are no longer such a big secret. However, I take issue with this bit: ... it's possible that you created a document in 2022 that you simply won't be able to open in 2023. The change will also cause problems if you open and work with decades-old files with any kind of regularity; files that use Type 1 fonts will begin generating lots of "missing font" messages ... As far as I know, office-type and layout-type apps do not typically embed fonts in the document. Instead, they store font-matching information (family name, weight etc) that will be used to find the best available fonts when the document is next opened, perhaps on a different system. Remember, it is only the old font format that is being dropped; the same classic, professional-quality font designs that people have been using for years or decades will still be available, just in the newer formats. So a proper font match, if it is installed, can still be found. A self-contained document format like PDF does embed fonts (typically only in subset form), but that has its own internal font representation, so it should not be affected by the demise of Type-1. This part is true, though: You'll also either need to convert any specialized PostScript Type 1 font that you may have paid for in the past or pay for an equivalent OpenType alternative. This article <https://www.prepressure.com/fonts/basics/history> is a good potted history of font formats (the important ones, at any rate). By the way, I don’t think the open-source FreeType library is dropping support for Type-1 font rendering any time soon. It still handles Multiple Master fonts, which Adobe gave up on a long time ago.

Windows Server Forgets What Time It Is
by Lawrence D'Oliveiro 17 Aug '23

17 Aug '23

Seems that, some years ago, Microsoft added a “feature” to Windows Server, called “Secure Time Seeding”. This was supposed to offer alternative ways for a server machine to keep track of the correct time, in the event of failures in the more usual mechanisms. Unfortunately, this “feature” only seems to have introduced a new source of problems, where the server can suddenly throw its date and time setting off by as much as several months, often with unfortunate consequences for the applications running on it <https://arstechnica.com/security/2023/08/windows-feature-that-resets-system…>. At this stage, Microsoft is still in the “no comment” stage of (not) responding to this problem. Reports of issues go right back to the introduction of the feature, back in 2016. They may only be happening intermittently, but it seems to me this is still enough to damage what trust there may still be left in Microsoft’s product.

Bad enough that that light, thin text is almost unreadable against a similarly-coloured background, I decided to search the site for “munich” to see if I could find a more recent item, and got this: <https://www.ip-watch.org/?s=munich>. In case they fix it later, the top part has this message: Deprecated: strlen(): Passing null to parameter #1 ($string) of type string is deprecated in /home/clients/5bc716f64eaa5eb2ef6cc74a6b9b690a/web/weblog/wp-content/plugins/wordfence/vendor/wordfence/wf-waf/src/lib/utils.php on line 445 and at the bottom it says “Not found, error 404” and that the page I am looking for (search results??) no longer exists. Who knew? Mind you, PHP is the only language where features can be marked “no longer deprecated” in later releases, so who knows, perhaps they will later decide to assign a meaning to finding the length of a string when the string isn’t actually a string ...

Should There Be an 'Official' Version of Linux?
by C. A. Fillekes 15 Aug '23

I was surprised, a couple years ago, to find that most of my gnome desktop applications had ceased being exportable to different machines' displays over the network. Even Firefox. Ordinary vanilla X11 is unwieldy, but it at least had that one key feature, and has had it since well before MS Windows ruined everything.

Should There Be an 'Official' Version of Linux?
by Peter Reutemann 14 Aug '23

'Why aren't more people using Linux on the desktop? Slashdot reader technology_dude shares one solution: Jack Wallen at ZDNet says establishing an "official" version of Linux may (or may not) help Linux on the desktop increase the number of users, mostly as someplace to point new users. It makes sense to me. What does Slashdot think and what would be the challenges, other than acceptance of a particular flavor? Wallen argues this would also create a standard for hardware and software vendors to target, which "could equate to even more software and hardware being made available to Linux." (And an "official" Linux might also be more appealing to business users.) Wallen suggests it be "maintained and controlled by a collective of people from users, developers, and corporations (such as Intel and AMD) with a vested interest in the success of this project... There would also be corporate backing for things like marketing (such as TV commercials)." He also suggests basing it on Debian, and supporting both Snap and Flatpak... In comments on the original submission, long-time Slashdot reader bobbomo points instead to kernel.org, arguing "There already is an official version of Linux called mainline. Everything else is backports." And jd (Slashdot user #1,658) believes that the official Linux is the Linux Standard Base. "All distributions, more-or-less, conform to the LSB, which gives you a pseudo 'official' Linux. About the one variable is the package manager. And there are ways to work around that." Unfortunately, according to Wikipedia... The LSB standard stopped being updated in 2015 and current Linux distributions do not adhere to or offer it; however, the lsb_release command is sometimes still available.[citation needed] On February 7, 2023, a former maintainer of the LSB wrote, "The LSB project is essentially abandoned." That post (on the lsb-discuss mailing list) argues the LSB approach was "partially superseded" by Snaps and Flatpaks (for application portability and stability). And of course, long-time Slashdot user menkhaura shares the obligatory XKCD comic... It's not exactly the same thing, but days after ZDNet's article, CIQ, Oracle, and SUSE announced the Open Enterprise Linux Association, a new collaborative trade association to foster "the development of distributions compatible with Red Hat Enterprise Linux." So where does that leave us? Share your own thoughts in the comments. And should there be an "official" version of Linux?' -- source: https://linux.slashdot.org/story/23/08/12/1835204 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Does Desktop Linux Have a Firefox Problem?
by Peter Reutemann 14 Aug '23

14 Aug '23

'OS News' managing editor calls Firefox "the single most important desktop Linux application," shipping in most distros (with some users later opting for a post-installation download of Chrome). But "I'm genuinely worried about the state of browsers on Linux, and the future of Firefox on Linux in particular..." While both GNOME and KDE nominally invest in their own two browsers, GNOME Web and Falkon, their uptake is limited and releases few and far between. For instance, none of the major Linux distributions ship GNOME Web as their default browser, and it lacks many of the features users come to expect from a browser. Falkon, meanwhile, is updated only sporadically, often going years between releases. Worse yet, Falkon uses Chromium through QtWebEngine, and GNOME Web uses WebKit (which are updated separately from the browser, so browser releases are not always a solid metric!), so both are dependent on the goodwill of two of the most ruthless corporations in the world, Google and Apple respectively. Even Firefox itself, even though it's clearly the browser of choice of distributions and Linux users alike, does not consider Linux a first-tier platform. Firefox is first and foremost a Windows browser, followed by macOS second, and Linux third. The love the Linux world has for Firefox is not reciprocated by Mozilla in the same way, and this shows in various places where issues fixed and addressed on the Windows side are ignored on the Linux side for years or longer. The best and most visible example of that is hardware video acceleration. This feature has been a default part of the Windows version since forever, but it wasn't enabled by default for Linux until Firefox 115, released only in early July 2023. Even then, the feature is only enabled by default for users of Intel graphics — AMD and Nvidia users need not apply. This lack of video acceleration was — and for AMD and Nvidia users, still is — a major contributing factor to Linux battery life on laptops taking a serious hit compared to their Windows counterparts... It's not just hardware accelerated video decoding. Gesture support has taken much longer to arrive on the Linux version than it did on the Windows version — things like using swipes to go back and forward, or pinch to zoom on images... I don't see anyone talking about this problem, or planning for the eventual possible demise of Firefox, what that would mean for the Linux desktop, and how it can be avoided or mitigated. In an ideal world, the major stakeholders of the Linux desktop — KDE, GNOME, the various major distributions — would get together and seriously consider a plan of action. The best possible solution, in my view, would be to fork one of the major browser engines (or pick one and significantly invest in it), and modify this engine and tailor it specifically for the Linux desktop. Stop living off the scraps and leftovers thrown across the fence from Windows and macOS browser makers, and focus entirely on making a browser engine that is optimised fully for Linux, its graphics stack, and its desktops. Have the major stakeholders work together on a Linux-first — or even Linux-only — browser engine, leaving the graphical front-end to the various toolkits and desktop environments.... I think it's highly irresponsible of the various prominent players in the desktop Linux community, from GNOME to KDE, from Ubuntu to Fedora, to seemingly have absolutely zero contingency plans for when Firefox enshittifies or dies...' -- source: https://news.slashdot.org/story/23/08/13/226217 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Mozilla To Bring Firefox Desktop Extension To Android Browser
by Peter Reutemann 12 Aug '23

12 Aug '23

'Scott DeVaney, writing at Mozilla blog: In the coming months Mozilla will launch support for an open ecosystem of extensions on Firefox for Android on addons.mozilla.org (AMO). We'll announce a definite launch date in early September, but it's safe to expect a roll-out before the year's end. Here's everything developers need to know to get their Firefox desktop extensions ready for Android usage and discoverability on AMO. For the past few years Firefox for Android officially supported a small subset of extensions while we focused our efforts on strengthening core Firefox for Android functionality and understanding the unique needs of mobile browser users. Today, Mozilla has built the infrastructure necessary to support an open extension ecosystem on Firefox for Android. We anticipate considerable user demand for more extensions on Firefox for Android, so why not start optimizing your desktop extension for mobile-use right away?' -- source: https://news.slashdot.org/story/23/08/11/1234201 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, Hamilton, NZ Mobile +64 22 190 2375 https://www.cs.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/
