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

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.

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.

Slack Now Strips Location Data From Images
by Peter Reutemann 16 May '20

16 May '20

'Slack has started to strip uploaded photos of their metadata. What may seem like an inconsequential change to how the tech giant handles storing files on its servers, it will make it far more difficult to trace photos back to their original owners. From a report: Almost every digital file -- from documents on your computer to photos taken on your phone -- contains metadata. That's data about the file itself, such as how big the file is, when it was created, and by whom. Photos and videos often include the precise coordinates of where they were taken. But that can be a problem for higher-risk Slack users, like journalists and activists, who have to take greater security precautions to keep their sources safe. The metadata inside photos can out sources, deanonymize whistleblowers, or otherwise make it easier for unfriendly governments to target individuals. Even if a journalist removes the metadata from a photo before publishing, a copy of the photo -- with its metadata -- may remain on Slack's servers. Whether a hacker breaks in or a government demands the data, it can put sources at risk' -- source: https://yro.slashdot.org/story/20/05/11/2051209 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/

ddr2 ram
by john 16 May '20

16 May '20

Some years ago, Windows Vista offered users who plugged in a USB flash drive the option of using the device as extra ram. I never actually tried this due to large amount of doubt about the functional ability of the claim. However I now have a number of Linux machines with DDR2 that I am unable to increase the physical memory of and wonder if this is a feasible option for these machines. Cheers John

Standby Fares For Those Flying Cloud
by Lawrence D'Oliveiro 14 May '20

14 May '20

New concept: “Spot” VMs on cloud services <https://www.theregister.co.uk/2020/05/13/azure_spot_vms/>. These are offered for a very low price, but equally the jobs run at very low priority, and are liable to be evicted at short notice--as little as 30 seconds, according to the article. They are there to fill up unused capacity that cannot be sold at the regular rate. But as soon as a customer appears willing to pay that rate, out you go.

3D File Manager As A Service
by Lawrence D'Oliveiro 13 May '20

This company called Saganworks is offering a navigable 3D world for accessing your files stored on their servers <https://blocksandfiles.com/2020/05/12/saganworks-virtual-reality-rooms-for-…>. This sort of thing has been done lots of times before, famously on SGI workstations (and seen in the “Jurassic Park” movie). I suppose Microsoft Bob also counts, in a way. Quote: “We don’t live in a 2D world, yet that’s how we’ve been retaining knowledge and memories from the time of early cave dwellers until now.” Speak for yourself, non-command-line user. Yes, the name is a contrived acronym, and also a homage to Carl Sagan ...
