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.

Firefox Finally Outperforming Google Chrome In SunSpider
by Peter Reutemann 16 Aug '23

16 Aug '23

'Michael Larabel writes via Phoronix: Mozilla developers are celebrating that they are now faster than Google Chrome with the SunSpider JavaScript benchmark, although that test has been superseded by the JetStream benchmark. Last week a new Firefox Nightly News was published that outlines that "We're now apparently beating Chrome on the SunSpider JavaScript benchmark!" The provided numbers now show Firefox easily beating Chrome in this decade-old JavaScript benchmark. The benchmarks come from AreWeFastYet.com. Meanwhile for the newer and more demanding JetStream 2.0 benchmark, Google Chrome continues to win easily over Firefox.

From The “How Not To Design A Website” Department
by Lawrence D'Oliveiro 15 Aug '23

15 Aug '23

Found a link to some past news items on this site reporting on Munich city’s back-and-forth migrations between Linux and Windows. The last linked item was this <https://www.ip-watch.org/2018/06/12/former-munich-mayor-warns-negative-effe…>. 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

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

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/
