Jitsi
by Michael Doob 10 Dec '20

10 Dec '20

Hi Everyone -- Am I the only one who had a jitsi failure last night? After a bit of a struggle just to log in, there was no way I could get the audio to work. I've never had a problem for previous meetings. Too bad I'm not a lip reader. I could see them moving. Was our attendance lower that what might be expected? While I'm here: it's dues-paying time for me. Do we have inteac e-transfers set up for our banking. I could make the direct deposit and avoid any fees being charged to MUUG. Cheers, Michael ------------------------------------------------------------------ Michael Doob Telephone: (204) 474-9796 Senior Scholar Department of Mathematics email: Michael.Doob(a)UManitoba.ca University of Manitoba Winnipeg, MB, Canada R3T 2N2 ------------------------------------------------------------------

CentOS 8 is dead - CentOS Stream?
by Alberto Abrao 09 Dec '20

09 Dec '20

As one of our topics yesterday, CentOS 8 will be gone in a few months. I mentioned being willing to migrate to Debian on my virtualization box. Still, as one commenter somewhere said, Red Hat owns the userspace on Linux. Think what you may about that, it is what it is. If any of you would rather just jump to CentOS Stream - which will be a test bed for the point-releases of RHEL, so less of a "fun ride" than Fedora Server - the process is (taken from https://centos.org/distro-faq/#q7-how-do-i-migrate-my-centos-linux-8-instal…) root@centos-linux# dnf install centos-release-stream root@centos-linux# dnf distro-sync root@centos-stream# cat /etc/centos-release CentOS Stream release 8 I am in the middle of this as I type this message. Will give feedback later. Kind regards, Alberto Abrao

Reminder: MUUG Online Meeting, Tonight, Dec 8, 7:30pm -- cal(1), Extended Round-Table & Show-and-Tell
by Gilbert E. Detillieux 08 Dec '20

08 Dec '20

A reminder that the MUUG online meeting will be on Jitsi this evening... The Manitoba UNIX User Group (MUUG) will be holding its next monthly meeting online, on Tuesday, December 8th, at 7:30pm: Extended Round-Table and Show-and-Tell We have a tradition of making the December meeting more of an informal, social gathering. This year, because we're meeting online, we've had to let go of some of the traditional aspects of this year-end meeting (like food), but we'll try to keep some. *Show us your favourite gadget!* As part of an extended round-table discussion, we'll try to keep the gadget show-and-tell. (This year, you don't have to haul it to the meeting site, but it will have to be small enough to show on your webcam!) If you have a cool device, something unusual, whether brand new or ready for the museum, there will be an opportunity to show it off. RTFM: cal(1) - A Histori-cal Look at Calendar Reform As part of the September 2016 meeting, we looked at cal(1), and its ilk (ncal and gcal), mostly from a utilitarian point of view. This time, we'll look at some of the historical development of this command, as well as some strange quirks of calendar reform. Why was the year 2000 a leap year, but 1900 wasn't? (At least for most of the world.) Why was 1700 a leap year in many Protestant countries, but not in Roman Catholic ones? What was going on in 1752 for England and her colonies? Gilbert Detillieux will answer these questions, as we delve into the politics and religion involved in calendar reform. Join the meeting: https://jitsi.merlin.mb.ca/muug.2020.12 Winnipeg Harvest We won't be able to collect food and cash donations this year, but please remember that the needs for some may be greater than usual. We encourage you to donate to Winnipeg Harvest, or your favourite local charity. https://winnipegharvest.org/donate/ The group holds its meetings at 7:30pm on the second Tuesday of every month from September to June. (There are no meetings in July and August.) Meetings are open to the general public; you don't have to be a MUUG member to attend.

I'm looking for an all-in-one
by Glen Ditchfield 12 Nov '20

12 Nov '20

I'm looking for a color printer/scanner/copier, suitable for printing a few pages every few weeks. My current device is connected by USB to a Mac that serves as a CUPS host and runs the scanner software, and that's just fine. I look at most of the modern features being offered and rate them somewhere between "meh" and "get off my lawn" (Alexa voice-enabled printing? Seriously?) but might be willing to grant access to the local Wi-Fi. Do you have any opinions on Linux-friendly, non-abusive devices?

Re: [RndTbl] Roundtable Digest, Vol 191, Issue 1
by Kevin K. 01 Nov '20

01 Nov '20

I have a Brother DCP-7065DN (scanner, copier, printer) which has been easy for me to set up with my Ubuntu Linux system. It's a black and white laser device and Brother has great steps for setting it up. It can be connected to your LAN network and communicates through my computer with USB. On the software side of things to use this device, I use XSane for the scanning, both in colour and black and white, with multiple resolution options. Copying is done on the device itself, and the printer options are very flexible from any document software I've used. I'm sure the colour laser variety by Brother is just as Linux-friendly, but you'd have to check it out on the Brother website. Basically, if you see Linux instructions for your device, then go with it, I say. I ended up with this particular model because I searched for Linux printer/scanner drivers and setup instructions, which ultimately led me to a very detailed setup page someone else had created which was sort of an addendum to the instructions provided by Brother. Good luck! -Kevin ________________________________ From: Roundtable <roundtable-bounces(a)muug.ca> on behalf of roundtable-request(a)muug.ca <roundtable-request(a)muug.ca> Sent: November 1, 2020 12:00 PM To: roundtable(a)muug.ca <roundtable(a)muug.ca> Subject: Roundtable Digest, Vol 191, Issue 1 Send Roundtable mailing list submissions to roundtable(a)muug.ca To subscribe or unsubscribe via the World Wide Web, visit https://muug.ca/mailman/listinfo/roundtable or, via email, send a message with subject or body 'help' to roundtable-request(a)muug.ca You can reach the person managing the list at roundtable-owner(a)muug.ca When replying, please edit your Subject line so it is more specific than "Re: Contents of Roundtable digest..."

With your infrequent printing schedule, such a device would give you endless troubles and expenses with dried-out, often unresurrectable, inkjet cartridges or nozzles. If colour is not needed, then it should be a laser device. Those are fine with infrequent printing, though with such low print volumes, you'd still have the issue that even toner does deteriorate after a few years of sitting in a cartridge. Back to inkjet devices: You could print a handful of useless "maintenance" pages every 5 days or so to keep the cartridges and nozzles in good condition, which would result in way more "maintenance" pages than real pages being printed over time, with a much higher cost per real page than normal. The dot-matrix printers of the distant past didn't have the above issues. :) :) Hartmut W Sager - Tel +1-204-339-8331 On Sat, 31 Oct 2020 at 18:00, Glen Ditchfield <GJDitchfield(a)acm.org> wrote: > I'm looking for a color printer/scanner/copier, suitable for printing a > few > pages every few weeks.

Skullspace presents, Hax weekend (virtual) hackerspace festival
by Mark Jenkins 17 Oct '20

17 Oct '20

Hey fellow MUUG members, I wanted to share the following live event I'm running for Skullspace today (Saturday) and tomorrow. Hax weekend (virtual) hackerspace festival https://hax.skullspace.ca/ There's a few other MUUG personalities on the presenter list. I would have mentioned this at RoundTable this past Tuesday, but I was running a tech rehearsal with my best devices and made the mistake of trying to come on to the Jitsi with an ill-suited device. My failed pitch to Hackaday.com covers some of how I put this event together: https://gist.githubusercontent.com/markjenkins/3002879c32602dce2df7a746f284… Happy Hacking! Mark Jenkins
