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 01 Sep '20

01 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 30 Aug '20

30 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/

Hey all! Been a while since our last LUV meeting. I am in the process of planning for September and given it will be the first time we are running a LUV main meeting online, we can be creative about the format. Any thoughts or ideas are welcome! Also, what topics should we discuss? Do you have a topic you like to hear about? Even better, do you have a topic you would like to talk about? The event will be held next Tuesday, September the 1st. Feel free to reply to this*, *or send an email to the committee ( luv-ctte(a)luv.asn.au) Thanks! + Alexar -- [image: image.jpg] *Alexar Pendashteh* technologist / social entrepreneur https://github.com/pendashteh

When we started this discussion we had this stripinska@Stripinska:~$ sudo zfs list NAME USED AVAIL REFER MOUNTPOINT alexandria 332G 1.06G 96K /alexandria Now having moved 47.3 GB of files to an external drive I have this. stripinska@Stripinska:~$ sudo zfs list NAME USED AVAIL REFER MOUNTPOINT alexandria 332G 782M 96K /alexandria What is eating my space? It is not the cache for Firefox as this is only 320M. How do I get it back before the box freezes. The more disk space I free the less available space I have. Stripes.
