'Infinite Mac' Project Lets You Boot Up Mac OS In Your Browser
by Peter Reutemann 03 Apr '22

03 Apr '22

'Ars Technica: What makes the ["Infinite Mac"] project unique isn't necessarily the fact that it's browser-based; it has been possible to run old DOS, Windows, and Mac OS versions in browser windows for quite a while now. Instead, it's the creative solutions that developer Mihai Parparita has come up with to enable persistent storage, fast download speeds, reduced processor usage, and file transfers between the classic Mac and whatever host system you're running it on. Parparita details some of his work in this blog post. Beginning with a late 2017 browser-based port of the Basilisk II emulator, Parparita wanted to install old apps to more faithfully re-create the experience of using an old Mac, but he wanted to do it without requiring huge downloads or running as a separate program as the Macintosh.js project does. To solve the download problem, Parparita compressed the disk image and broke it up into 256K chunks that are downloaded on demand rather than up front. "Along with some old fashioned web optimizations, this makes the emulator show the Mac's boot screen in a second and be fully booted in 3 seconds, even with a cold HTTP cache," Parparita wrote. CPU usage was another issue. Old operating systems and processors didn't really distinguish between active and idle processor states -- your computer was either on or off. So when you emulate these old systems, they'll ramp one of your CPU cores to 100% whether you're actually using the emulator or not. Parparita used existing Basilisk II features to reduce CPU usage, only requiring full performance when "there was user input or a screen refresh was required." Infinite Mac won't run later releases of classic Mac OS (including 8.5, 8.6, and 9) because those releases ran exclusively on PowerPC Macs, dropping support for the old Motorola 68000-based processors. Emulators like QEMU are capable of emulating PowerPC Macs, but (at least as far as I am aware) there are no easy browser-based implementations that exist. Not yet, anyway.' -- source: https://apple.slashdot.org/story/22/04/01/2032251 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/

StarFive VisionFive RISC-V Single Board Computer
by Lawrence D'Oliveiro 29 Mar '22

29 Mar '22

A few videos have appeared on YouTube in the last few days about this VisionFive board. Instead of an ARM chip, it uses a RISC-V CPU, but of course it runs Linux. It’s quite clearly gunning for the Raspberry π market, both in its configuration and pricewise, though I don’t think it’s as powerful as a π 4. StarFive Technology have a few quite technical-looking videos on their channel, seemingly going into details like how the OS boots. I’ll see if I can find a decent hands-on review.

Mozilla To Offer MDN Premium Tier
by Lawrence D'Oliveiro 28 Mar '22

28 Mar '22

The Mozilla Developer Network <https://developer.mozilla.org/en-US/docs/Web> is a really good resource if you’re doing any kind of web development. I’ve found all kinds of well-explained technical detail there that is simply missing from other sources (*cough* w3schools *cough*). Now Mozilla is trying to get some money from it. They’re not taking anything away from existing access, they are merely offering extra personalization features on a paid basis <https://www.theregister.com/2022/03/24/mozillas_mdn_subscription/>.

'Rolling Rhino' Tool Converts Ubuntu Into a Rolling Release
by Peter Reutemann 28 Mar '22

28 Mar '22

'"Rolling Rhino is a tool long ago created by Martin Wimpress, who until recently was part of the Canonical team," one Linux blog pointed out recently. "What it does is basically change the repositories of the DailyLive developers...." Neowin sees it as a competitive advantage. After more than 17 years, there's a way to get a Ubuntu distro offering the same "rolling" release cycles that helped popularize Arch Linux: While there are many positive qualities that would draw a user into the world of Arch, its headlining feature would be the one that remains the most relevant in today's world of continuous integration and delivery and that's its rolling release strategy. While I don't think Judd Vinet could have predicted the proliferation of DevOps or the massive shift to cloud computing, it must be interesting to see that the entire industry is following the Arch strategy in all sorts of different places. One could even argue that Microsoft Windows has become a rolling release. While many of Arch's contemporaries have joined the fray, one notable open-source giant has yet to make the leap. Rolling Rhino looks to change that by converting Ubuntu into a rolling release.' -- source: https://news.slashdot.org/story/22/03/27/0035232 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/

KDE's New Swipe Gesture Makes Windows 11 Look Bad
by Peter Reutemann 28 Mar '22

28 Mar '22

'"Microsoft has been struggling to reach a state of convergence between tablet and desktop ever since Windows 8 and the original Surface," argues Neowin, adding "If we're using Windows 11 as a barometer of their progress, they'll likely never get there...." But meanwhile, writes Slashdot reader segaboy81, "KDE's new swipe gesture is awesome. It's about 1000% smoother than the overview in Windows 11 and the swiping mechanism is easier, too. Is KDE getting better for tablets?" >From Neowin's report: Starting in KDE Plasma 5.25, users with touch screen devices will be able to enter their tasks and virtual desktops overview by simply swiping down from the top edge, but with a special twist. The scale of the windows directly follows the path of your finger. The result is every bit as fluid as you might imagine. While you can achieve the same result in Windows 11 with a simple three-finger swipe up, this implementation looks great and performs great too.' -- source: https://tech.slashdot.org/story/22/03/27/201245 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/

Asahi Linux Is Reverse-Engineering Support For Apple Silicon, Including M1 Ultra
by Peter Reutemann 27 Mar '22

27 Mar '22

'Ars Technica: For months, a small group of volunteers has worked to get this Arch Linux-based distribution up and running on Apple Silicon Macs, adapting existing drivers and (in the case of the GPU) painstakingly writing their own. And that work is paying off -- last week, the team released its first alpha installer to the general public, and as of yesterday, the software supports the new M1 Ultra in the Mac Studio. In the current alpha, an impressive list of hardware already works, including Wi-Fi, USB 2.0 over the Thunderbolt ports (USB 3.0 only works on Macs with USB-A ports, but USB 3.0 over Thunderbolt is "coming soon"), and the built-in display. But there are still big features missing, including DisplayPort and Thunderbolt, the webcam, Bluetooth, sleep mode, and GPU acceleration. That said, regarding GPU acceleration, the developers say that the M1 is fast enough that a software-rendered Linux desktop feels faster on the M1 than a GPU-accelerated desktop feels on many other ARM chips. Asahi's developers don't think the software will be "done," with all basic M1-series hardware and functionality supported and working out of the box, "for another year, maybe two." By then, Apple will probably have introduced another generation or two of M-series chips. But the developers are optimistic that much of the work they're doing now will continue to work on future generations of Apple hardware with relatively minimal effort. [...] If you want to try Asahi Linux on an M1 Mac, the current installer is run from the command line and requires "at least 53GB of free space" for an install with a KDE Plasma desktop. Asahi only needs about 15GB, but the installer requires you to leave at least 38GB of free space to the macOS install so that macOS system updates don't break. From there, dual-booting should work similarly to the process on Intel Macs, with the alternate OS visible from within Startup Disk or the boot picker you can launch when your start your Mac. Future updates should be installable from within your new Asahi Linux installation and shouldn't require you to reinstall from scratch.' -- source: https://linux.slashdot.org/story/22/03/25/2333245 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/

Ted Nelson Quote From 1995
by Lawrence D'Oliveiro 26 Mar '22

26 Mar '22

I was prompted to browse through old scanned issues of “Byte” magazine (available from vintageapple.org) after watching a YouTube video by a guy who has collected a complete set of actual paper issues <https://www.youtube.com/watch?v=0lU537upx3c>. In the November 1995 issue, there was a back-page column by Ted Nelson (originator of the terms “hypertext” and “hypermedia”) called “Things To Come”, where he casually threw out a bunch of prognostications on how he thought computing would develop. I was struck by this quote, under the title “Tomorrow’s killer applications”: My hope is that there will be no more applications, because future software will be set up to be tied together, piped together, scripted together. I would say that has partially come true. We have a lot of software components now that can be reused via scriptable APIs, or even just shell scripts. However, nobody considered that such usage is the anithesis of how GUIs work. Most of the predictions in the rest of the column were, shall we say, a bit wide of the mark. For example, the next sentence after the above was “The real killer applications will be nanotech bugs that escape”, which is perhaps best left to just lie there quietly ...

topic for next wlug meeting?
by Peter Reutemann 25 Mar '22

25 Mar '22

Hi everyone At this stage, we don't have a speaker lined up for this month's virtual meeting (we're still at the Red traffic light). With the current world situation and increasing cyber security threats, I was wondering whether we should have a meeting where we discuss together (and showcase) various tools that we can run or use to make our online life safer. A non-exhaustive list: firewalls, virus scanners, rootkit detectors, VPNs. Thoughts?

Two Years After Chrome and Edge, Firefox is Getting AV1 Hardware Acceleration
by Peter Reutemann 24 Mar '22

24 Mar '22

'Firefox is finally gaining proper AV1 support. Neowin reports: According to an update made to a post on Bugzilla, the Mozilla Foundation is finally ready to add hardware acceleration for the AV1 video format. Developers plan to implement improved AV1 support in the upcoming release of Firefox 100, scheduled to arrive on May 3, 2022. Hardware acceleration for AV1 video brings several noticeable benefits to customers. The standard developed by Alliance for Open Media and initially released in March 2018 offers better video compression than H.264 (about 50%) and VP9 (about 20%). Shifting AV1 video processing from software to hardware improves efficiency and reduces energy consumption, resulting in better battery life on tablets and laptops. Google and Microsoft announced hardware-accelerated AV1 video in Chrome and Edge in late 2020. Mozilla, on the other hand, did not rush to introduce improved AV1 support in Firefox. While it is easy to dunk on Firefox, there is a reason why developers took their time. Hardware-accelerated AV1 video is not something you can add to any computer with Windows 10, and it requires a PC with the most recent and powerful hardware.' -- source: https://news.slashdot.org/story/22/03/23/1359219 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/

Android's Messages, Dialer Apps Quietly Sent Text, Call Info To Google
by Peter Reutemann 23 Mar '22

23 Mar '22

'Google's Messages and Dialer apps for Android devices have been collecting and sending data to Google without specific notice and consent, and without offering the opportunity to opt-out, potentially in violation of Europe's data protection law. From a report: According to a research paper, "What Data Do The Google Dialer and Messages Apps On Android Send to Google?" [PDF], by Trinity College Dublin computer science professor Douglas Leith, Google Messages (for text messaging) and Google Dialer (for phone calls) have been sending data about user communications to the Google Play Services Clearcut logger service and to Google's Firebase Analytics service. "The data sent by Google Messages includes a hash of the message text, allowing linking of sender and receiver in a message exchange," the paper says. "The data sent by Google Dialer includes the call time and duration, again allowing linking of the two handsets engaged in a phone call. Phone numbers are also sent to Google." The timing and duration of other user interactions with these apps has also been transmitted to Google. And Google offers no way to opt-out of this data collection. [...] Both pre-installed versions of these apps, the paper observes, lack app-specific privacy policies that explain what data gets collected -- something Google requires from third-party developers. And when a request was made through Google Takeout for the Google Account data associated with the apps used for testing, the data Google provided did not include the telemetry data observed.' -- source: https://yro.slashdot.org/story/22/03/22/2146234 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/
