Linux distro review: Fedora Workstation 32
by Peter Reutemann 20 May '20

20 May '20

'Today's Linux distro review is one I've been wanting to do for quite some time—Fedora Workstation. Fedora is one of the heavyweight desktop distros of the Linux world, with a vibrant community and a strong presence at every open source convention I've ever attended. (Remember physically attending events? Ars remembers.) I never felt particularly drawn to Fedora myself, because it's a bleeding-edge distro—one targeted to the very newest software, possibly at the expense of stability. That's not what I personally want in an operating system—I fix broken things professionally; I'd prefer not to fix them personally any more than I have to. But as one of the few distros using the next-generation Wayland display server by default, Fedora made me very curious indeed. Although the screenshots taken throughout this review are of virtual machines, my first installation of Fedora Workstation (ever!) was bare metal, on the HP Dragonfly Elite G1.' -- source: https://arstechnica.com/gadgets/2020/05/linux-distro-review-fedora-workstat… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

“To Fix Social Media, We Need To Introduce Digital Socialism”
by Lawrence D'Oliveiro 20 May '20

20 May '20

Some may find this opinion piece <https://www.aljazeera.com/indepth/opinion/fix-social-media-introduce-digita…> a bit too political, I don’t know. But he does mention some interesting open-source software projects, like the various “Fediverse” networks of decentralized social-media servers, and the “LibreSocial” project, which is trying to get rid of what little centralization still exists in those networks. Where I suppose it gets controversial is where he suggests that funding for such projects could be raised by taxing the existing Big Tech firms. But certainly many would agree the open-source projects he mentions are worth pursuing regardless.

Microsoft Launches Windows Terminal 1.0, Unveils GPU Support and Linux GUI Apps in WSL
by Peter Reutemann 20 May '20

20 May '20

'At Build 2020 today, Microsoft gave developers a slew of new tools to coax them into using Windows over macOS or Linux. From a report: Windows Terminal is now out of preview for enterprises, and Windows Subsystem for Linux (WSL) 2 is getting support for GPUs, Linux GUI apps, and a simplified install experience. Microsoft even released a Windows Package Manager in preview. Windows 10 runs on 1 billion monthly active devices (PCs, Xbox One consoles, and HoloLens devices), making it a massive platform for developers to target. [...] Microsoft today released Windows Terminal 1.0, which means it is stable for enterprise use. The open source application features multiple tabs, panes, tear-away windows, shortcuts, Unicode and UTF-8 character support, emojis, ligatures, extensions, GPU-accelerated text rendering engine, and custom themes, styles, and configurations. Windows Terminal is for users of PowerShell, Cmd, WSL, and other command-line tools. Microsoft also unveiled WSL improvements today, including support for GPUs, Linux GUI apps, and a simplified install experience. WSL is a compatibility layer for running Linux binary executables natively on Windows. Microsoft first shared it was working on WSL 2 a year ago at Build 2019. WSL 2 is slated to arrive in the next major Windows 10 update coming later this month (brilliantly called the Windows 10 May 2020 Update), but it won't have these new features. In the second half of the year, WSL 2 will get support for GPU compute workflows.

Chrome 83 Released With Enhanced Privacy Controls, Tab Groups Feature
by Peter Reutemann 20 May '20

20 May '20

'Google has released today version 83 of its Chrome web browser, one of the most feature-packed Chrome updates released since the browser's initial launch back in 2009. From a report: Today's v83 release includes a slew of new features. These include enhanced privacy controls, new settings for managing cookie files, a new Safety Check option, support for tab groups, new graphics for web form elements, a new API for detecting barcodes, and a new anti-XSS security feature, among many many others. The reason why Chrome 83 includes so many features is because Google canceled the Chrome 82 release due to the ongoing coronavirus pandemic. As a result, some of the Chrome 82 features were pushed into Chrome 83, while others were rescheduled for later this year.' -- source: https://slashdot.org/story/20/05/19/185244 Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

meeting next Monday
by Peter Reutemann 20 May '20

20 May '20

Hi everyone For the meeting next week, the idea was to have a distro showdown. Since not everyone had experience yet with BigBlueButton, I would like to offer a trial run on Sunday night 8pm for the presenters. That should give them a chance to sort out video and audio. I'll send out a test link to the presenters off-list later on in the week. So far, I've got: - Ian - Ubuntu 20.04 - Tom - GhostBSD - Peter - Manjaro (never used it, but we can explore it together) Anyone else wanting to demo a distro? Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

ZFS versus RAID: Eight Ironwolf disks, two filesystems, one winner
by Peter Reutemann 19 May '20

19 May '20

'This has been a long while in the making—it's test results time. To truly understand the fundamentals of computer storage, it's important to explore the impact of various conventional RAID (Redundant Array of Inexpensive Disks) topologies on performance. It's also important to understand what ZFS is and how it works. But at some point, people (particularly computer enthusiasts on the Internet) want numbers. First, a quick note: This testing, naturally, builds on those fundamentals. We're going to draw heavily on lessons learned as we explore ZFS topologies here. If you aren't yet entirely solid on the difference between pools and vdevs or what ashift and recordsize mean, we strongly recommend you revisit those explainers before diving into testing and results. And although everybody loves to see raw numbers, we urge an additional focus on how these figures relate to one another. All of our charts relate the performance of ZFS pool topologies at sizes from two to eight disks to the performance of a single disk. If you change the model of disk, your raw numbers will change accordingly—but for the most part, their relation to a single disk's performance will not.' -- source: https://arstechnica.com/gadgets/2020/05/zfs-versus-raid-eight-ironwolf-disk… Cheers, Peter -- Peter Reutemann Dept. of Computer Science University of Waikato, NZ +64 (7) 858-5174 http://www.cms.waikato.ac.nz/~fracpete/ http://www.data-mining.co.nz/

Re: wlug Digest, Vol 347, Issue 17 - DishTV Box
by tom butz 19 May '20

19 May '20

Hi John, I've been using the cheap one (99 dollars) and it works well. They expect the hard-disk/memory stick to be formatted FAT32. The system could do that for you. The recording format is proprietary: it's .mpg, but if you play it back, there is an enormous amount of jitter every 5 seconds or so. There is no documentation, maybe because FreeView told them to keep it secret. The USB-connection is USB2 and supplies 500 mA of power: that should be enough for a memory stick but not an ordinary HD (they usually draw about 1000 mA). I've kept an old HD out of a notebook and use it with an adapter. It's slow but I've never lost anything. Maybe there are Y-connectors around that would bump the HD's power to 1000 mA, but I've not managed to find one. The system records in ordinary density and doesn't use a lot of space. As everything is so proprietary I haven't found a way to transfer/add parts to another HD/stick. Everything sits in 1 directory with a few subdirectories. Transferring the stuff to a computer would work if you filmed the TV-screen. You would then also be able to cut out the ads. I've read somewhere that there are devices that would record HDMI-output (which the DishTV provides) on a USB-device, so that should do the job. Gameplayers use something like that to record their moves... Just an aside: recording OnDemand movies: easy if you use 'simplescreenrecorder' (Windows and Linux). It creates an MKV-file you can edit. Tom.

dish tv

Hi all' Does anyone know the file format for the Dish TV sat box?? I have a replacement empty drive. No File allocation and wonder if the Dish box will format the disk to it's own system? Cheers John.
