[Online event described will be at 9am Sunday AEST, Melbourne time.] The first virtual meeting of CABAL, the LUG that normally meets in West Menlo Park, California (which as a reminder is one of the relatively sane parts of the USA). Thanks again to Trent W. Buck for the cool timezone-dumping trick, which he'll note I swiped. There will be no special topic, though I might give a briefing about my experience installing in a tearing hurry and administering Jitsi Meet on Amazon EC2 to provide one of major functions of the recent World Science Fiction Convention ('Worldcon') in Wellington, New Zealand, when it was obliged to operate as the first-ever virtual Worldcon. ----- Forwarded message from Rick Moen <rick(a)linuxmafia.com> ----- Date: Sat, 12 Sep 2020 00:26:42 -0700 From: Rick Moen <rick(a)linuxmafia.com> To: conspire(a)linuxmafia.com Subject: [conspire] CABAL meetings of the apocalypse, Saturday, Sept. 12, 4pm Organization: If you lived here, you'd be $HOME already. Hi ho! Seeing that the world is falling apart, the sky is the colour of a dead television channel, and the air is barely breathable, let's get together on Jitsi Meet! CABAL Virual Edition: Saturday, Sept. 12, 2020, 4pm - 8pm Pacific Daylight Time.[1] Where? Here, via videoconferencing: http://meet.jit.si/cabal You will need: o Computer w/supported Web browser. Best results reported with: o Chromium o Chrome o Microsoft Edge v. 79.0.309 or later o (some others, e.g., Firefox, might work but are not guaranteed) o A computer with mic and speakers/headphones. Headphones/earbuds are recommended (because they avert audio feedback loops). Upon joining @ that URL, your browser will probably ask if the page may have permission to connect to your microphone and speaker. Say yes. If you haven't done computer videoconferencing before: o You can check your setup for problems at https://test.webrtc.org/ . (Don't worry about minor bobbles like 'Reflexive connectivity' getting dinged.) o You might want to show up 15 minutes early, to thrash out problems. (Problems are common during first-time videoconferencing.) I will have fresh garlic bread and other home cooking. You probably won't, unless you're in my household, but, hey, that's the year 2020 for you. I expect we'll continue with 2nd Saturday 4-8 pm online CABAL meetings for the duration of the Martian Death Flu. When will reality get restored? Haha. "Der mentsh trakht un got lakht." I will promise with extreme insincerity to give a prize to the farthest flung videoconfercing participant. Astronauts calling from the ISS will automatically win. [1] If not in the Pacific Daylight Time time zone, check using https://www.worldtimebuddy.com/ Or try something lik this Bourne shell recipe (tested on Debian): :r! grep worldclock .bashrc alias worldclock='zdump America/{Los_Angeles,Mexico_City,New_York,Sao_Paulo} Europe/{London,Berlin,Moscow} Asia/Calcutta PRC Japan Australia/{Perth,Melbourne}' -- Cheers, "My hot flight attendant asked how I like my coffee.

PERC wasted space
by Russell Coker 11 Sep '20

11 Sep '20

I put a 1TB SATA disk in a Dell server with PERC RAID controller and configured that disk as a single virtual disk (IE the disk gets a RAID signature the PERC likes and is passed through to the OS). The disk when viewed on a regular SATA controller has 1953525168 sectors, when it goes through the PERC it has 1952448512 sectors, that is 525MB less space when going through the PERC! That's 1% of a 500G SSD. Is there any way to configure PERC to reduce it? Is using "HBA" mode worthwhile? -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

CamLink / Linux / Bullseye
by Brian May 06 Sep '20

06 Sep '20

Hello, I have a CamLink original which worked fine under Debian buster. But then I upgraded to Debian Bullseye. Now I no longer get the vl4 driver for the device. Running a Buster VM on the computer, and then redirecting the USB port inside the VM, this works fine. But ideally would like to get this working without a VM. Any ideas on how to debug this issue? The closest I can see is this bug report: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=966541 - but I don't get any stack trace in my kernel log files. Also this is Camlink, not the newer CamLink 4K. The logs I do get (tail -f /var/log/*.log) after plugging in the device are: ==> /var/log/kern.log <== Aug 24 09:05:13 canidae kernel: [43925.738496] usb 1-1: new high-speed USB device number 12 using xhci_hcd Aug 24 09:05:13 canidae kernel: [43925.889687] usb 1-1: New USB device found, idVendor=534d, idProduct=2109, bcdDevice=21.00 Aug 24 09:05:13 canidae kernel: [43925.889692] usb 1-1: New USB device strings: Mfr=1, Product=0, SerialNumber=0 Aug 24 09:05:13 canidae kernel: [43925.889695] usb 1-1: Manufacturer: MACROSILICON Aug 24 09:05:13 canidae kernel: [43925.893805] hid-generic 0003:534D:2109.000A: hiddev0,hidraw0: USB HID v1.10 Device [MACROSILICON] on usb-0000:00:14.0-1/input4 ==> /var/log/user.log <== Aug 24 09:05:13 canidae mtp-probe: checking bus 1, device 12: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-1" Aug 24 09:05:13 canidae mtp-probe: bus: 1, device: 12 was not an MTP device Aug 24 09:05:13 canidae mtp-probe: checking bus 1, device 12: "/sys/devices/pci0000:00/0000:00:14.0/usb1/1-1" Aug 24 09:05:13 canidae mtp-probe: bus: 1, device: 12 was not an MTP device ==> /var/log/daemon.log <== Aug 24 09:05:13 canidae rtkit-daemon[1452]: Supervising 7 threads of 2 processes of 2 users.

September Main Meeting
by Russell Coker 02 Sep '20

02 Sep '20

The meeting went well, we had some interesting discussions about things to do for LUV. I had the browser tab open for hours after I had stopped listening. When I closed the tab at 1:40AM there were still people talking. We should have these meetings more often. https://web.archive.org/web/20200510230233/https://luv.asn.au/ One issue that was discussed is copying data from the old web site. The above URL has the Wayback Machine link for the LUV web site. We need volunteers to go through that and find what's worth copying to the new web site. I don't think that a 1:1 copy would be a good idea, some things can be done differently. For example I think that the FAQ should be a page linked at the top rather than a link in the sidebar that is less likely to be seen. If you are interested in helping out with this then contact me off-list. We had at most 26 "users" in the room (I was 2 "users" so I think 25 unique people). We did use most of the available network bandwidth for the server when we had more than 6 people sending video streams. If we keep the number of active video cameras low we could have many more users, I think 50+ is quite possible. I think that if we promote our next online meeting to Linux Australia we will be able to handle the load. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Hack Nights
by Russell Coker 01 Sep '20

01 Sep '20

During the LUV video meet we discussed having hack nights with BBB for video conferencing. There was interest in making the first session about learning the Go programming language. The idea is that people would join the session knowing little about it, and just play around writing some code while discussing their problems with others. Who is interested in this and when should we run it? I think some evening at 6PM or 7PM would be best or maybe during the day on a weekend. Maybe Saturday mid-day. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

What time of the day is best for our Online Main Meeting?
by Alexar Pendashteh 31 Aug '20

31 Aug '20

We have an upcoming Main Meeting in a few days and it will be the first time we are running it online! Traditionally we would start at 7pm and wrap at around 9pm followed by dinner at a local restaurant. (feels like the past life!) However, now the event is online and almost all the reasons led to a 7pm start are invalid! Now the question is: *What time is best to start an Online Main Meeting*? Options we can consider are: *12pm - 2pm* *5pm - 7pm* *7pm - 9pm* *8pm - 10pm* Please let me know by replying to this email or contacting the committee at <luv-ctte(a)luv.asn.au>. Ideally we will settle on a time that works the best for most of our community, especially those who would previously find it difficult to attend in-person meetings due to distance or family commitment, etc. For that reason I would like to hear from anyone who has a preference, especially if: - you live inside the curfew zone. - you are a parent or a carer - you work between 9 to 5 (if that still is a thing for some?) - or for any other reason there is a limit on the range of hours you can attend online meetings. It's worth noting that the meeting will be accessible on a desktop browser and Android phones and iPhones. + Alexar -- [image: image.jpg] *Alexar Pendashteh* technologist / social entrepreneur https://github.com/pendashteh

copy and paste, under Wayland, and to and from an XTerm, was relating to dl audio and video
by Mark Trickett 31 Aug '20

31 Aug '20

Hello Craig, Many thanks for your excellent posts, I am learning more. However I have Debian 10, nominally up to date, and it has Wayland with Gnome as the desktop. I am finding it very frustrating that I cannot copy and paste to and from the XTerm window. I used to be able to do with earlier terminal emulation under the XWindows system. I used it to be able to copy text from a terminal into an email, and commands back from email, ensuring that I did not make typos. I do understand that there can be security issues if used without a measure of care and thoughtful, but it also has much merit when coping with some of the regular expressions that come up as examples in email and on web pages. Regards, Mark Trickett

LUV web site
by Russell Coker 31 Aug '20

31 Aug '20

Our Drupal web site was very outdated and had security issues. I've replaced it with a Wordpress site. One advantage of Wordpress is that upgrades are generally very easy, it will update the database for you. The only potential hassle of Wordpress upgrades is plugin compatibility, but with Drupal you have plugin issues as well as issues of the core product being difficult to update. Currently there is little content, but we will add some content from the old site shortly. Also I will soon have the LUV Wiki going again. Maybe tomorrow. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/

Re: [MLUG] Advice needed about ZFS
by stripes theotoky 30 Aug '20

30 Aug '20

Thank you all for the very helpful advice:- If I understand you all the problems are ZFS is choking because I don't have enough disk space. The reason I don't have enough disk space is because the files I deleted are still in the old snapshots, plus it was already pretty full. This seems like a good way forward but is it really and if so how do I do it? First things first ZFS is choking due to lack of disk space. However, I have a lot of totally unused diskspace on a windows partition so how can I reduce the windows partition and increase the ZFS to stop it choking. It has 560GB of which I do not need more than 200max to leave for Windoze. Gparted apparently doesn't like ZFS but does this matter? I can I assume use it to shrink the Windows partition and free up about 360GB, then how do I expand the ZFS to use that free space? Second, I have checked /etc/cron and find auto snap shot commands for hourly, daily, weekly & monthly hourly = 24, daily = 31, weekly = 8, monthly = 6. It seems I could change that to hourly = 24, daily = 7, weekly = 4, monthly = 6 and get pretty much the same coverage with a lot less snapshots. Listing snapshots shows some from 2019, where are they coming from as with monthly only storing 6 months there shouldn't be anything newer than February 2020 or am I not understanding something here? The computer is a Lenovo W541 laptop, the longer term plan is to double the memory to 32GB and put a 2TB SSD in this box. Does that sound sensible? In the meantime, a thorough backup is running in at least two external drives (one incremental and one fresh). Stripes.

LUV Wiki
by Russell Coker 29 Aug '20

29 Aug '20

I'm getting the LUV Wiki going again. Would anyone like to help test it? The Wiki has been broken for years because the old Drupal installation required an old version of PHP and a routine system upgrade had installed a new version of MediaWiki that needed a newer PHP. I have configured things to support multiple versions of PHP running at the same time. Also while I was at it I set up HTTP/2 and mod_pagespeed. -- My Main Blog http://etbe.coker.com.au/ My Documents Blog http://doc.coker.com.au/
