ot: headphone jac replacement?
by Karen Lewellen 23 Apr '21

23 Apr '21

I might add during the current lock down? Here is the scoop The primary device i use as my computer's speech synthesizer source has a 3.5 inch headphone jack, which has been getting looser over the past week or so. While I had hoped to find a way to tighten it before a disconnect, that hoped was dashed this afternoon. I do have the jac, in fact I have a spare, what I am wondering though is a couple of things. first, if I want to try, or must try reattaching this myself, which tool do I need? screwdriver, or wrench?..or something else? If I want it done by someone else, for which I would happily pay even if moving the machine might be a dance, where in Toronto might I take it in for the work? In theory it is rather important, the replacement synthesizer is s slight fire risk, as its casing is broken around the plug in area for its adapter. Also, it sounds like it has a could, which may become frustrating as I use my computer rather a great deal these days. Ideas? Thanks, Karen

Follow-on from Evan's talk: WSLg (graphics!)
by Stewart C. Russell 22 Apr '21

22 Apr '21

I see that MS's WSL preview release that came out today now has graphics support via Wayland. It's got some clever stuff behind it, and is explained here: WSLg Architecture | Windows Command Line — https://devblogs.microsoft.com/commandline/wslg-architecture/ Accelerated graphics and a built-in Pulse Audio server. Rather nicely done. cheers, Stewart

Docker, NodeJS and complexity
by William Witteman 22 Apr '21

22 Apr '21

I have some existing projects to contribute to that use NodeJS and Docker, and I am finding that getting set up to work on them is extremely daunting. I have never really used Docker. I have never really used NodeJS/npm/etc. I do know Javascript, but I don't build projects like this - it reminds me of Ruby-on-Rails, which I found to be a huge snarl of complexity. I know that the initial development was done on Macs, but in theory at least, I should be able to set up the Docker container and use that to get me into an equivalent development environment, but I don't really know how. Does anyone have a Debian-flavoured tutorial for setting up Docker/NodeJS so that I can build and run someone else's code? Thanks!

In order to screw on the ring, some of the threads from the audio jack must be exposed. Otherwise the ring would not be able to grab on and tighten. You don't need too many threads. Put the thread locker on those few threads, reinstall the ring and you should be good. Or put the thread locker on the inside of the ring. Without the ring, the audio jack may have rotated and might have interfered with the audio wires, possibly kinking them.

If the file /sys/firmware/acpi/tables/MSDM exists (it's read-only to root), there's probably a key embedded in there you can pull out with strings Stewart

Remote Connection/Boot Woes
by Peter King 14 Apr '21

14 Apr '21

There is a computer several hundred kilometres distant from me that I use for backing up data. The other day I had to reboot it, and things have not been the same. Most of the time I can't get in: my ssh connection hangs on the key exchange (usually expecting KEX_ECHD or some such). But every now and then, if the wind is right, I get through that -- and once I managed to get all the way in, though it hung without giving me a command-line prompt. The messages given (using ssh -vvv) made me suspect that it's the window size of the packets. In some sense that's good news, since I know there is a firmware bug in the ethernet driver so I have to set the mtu < 1500 (and I usually set it to 1492 after rebooting). Thing is, I can't log on, so I can't reset the mtu, so ... Apart from having someone else go reboot the machine, is there anything I can do at a distance? (Apart from despair, that is; I have that covered.) Probably not. But the knowledgeable people on this list often surprise me with things I didn't know about or thought impossible. -- Peter King peter.king(a)utoronto.ca Department of Philosophy 170 St. George Street #521 The University of Toronto (416)-946-3170 ofc Toronto, ON M5R 2M8 CANADA http://individual.utoronto.ca/pking/ ========================================================================= GPG keyID 0x7587EC42 (2B14 A355 46BC 2A16 D0BC 36F5 1FE6 D32A 7587 EC42) gpg --keyserver pgp.mit.edu --recv-keys 7587EC42

Raspberry Pi High-Availability / Remote Serviceable Solution
by Scott Sullivan 13 Apr '21

13 Apr '21

This is a follow on from my talk back November. Which at the GTALUG this evening I gave a small follow up. https://www.youtube.com/watch?v=cwESAjUBuj0 At the end of the original talk I discussed having issue with electrical isolation on the USB serial adapter. I've since solved that with an inexpensive part that's exactly fit for purpose. Below is the parts list: * USB-C to Serial Port UART Board Module Isolated USB to TTL Module 3.3V https://www.aliexpress.com/item/1005001644508314.html * TP-Link Jetstream 10-Port Gigabit Smart Switch with 8-Port PoE+ https://www.amazon.ca/gp/product/B0141JX92G/ * Dupont Crimping Tool https://www.amazon.ca/gp/product/B087QY413W/ * JST-XHP Housings and Connectors https://www.amazon.ca/gp/product/B07MBCLPBK/ * USB C to USB 2.0 A Cables https://www.amazon.ca/gp/product/B01ASXBY62/ * GeeekPi Raspberry Pi 4 PoE HAT https://www.amazon.ca/gp/product/B0833PP65P I also showed off my Build of the Raspberry Pi modular rack, constructed from the design by Uptime Labs. https://uplab.pro/2020/12/raspberry-pi-server-mark-iii/ I have a second one of these I printed and assembled but don't actually need. If someone interested, I'd sell if for $100 to cover the cost of the 5 case fans, steel rod and full spool of filament used in it's construction. -- Scott Sullivan

TIL: rtcwake / wakealarm
by Stewart C. Russell 12 Apr '21

12 Apr '21

This may be old news to many of you, but today I learned you can have the computer's real time clock boot your machine at a specific time. The more proper way seems to be to use the 'rtcwake' command, but you can also do it by writing the timestamp of the startup time to /sys/class/rtc/rtc0/wakealarm Some more details of the /sys method - https://www.raspberrypi.org/forums/viewtopic.php?f=63&t=309093&p=1849326&si… cheers, Stewart

[GTALUG-Announce] Meeting Tomorrow
by hi＠gtalug.org 12 Apr '21

12 Apr '21

<https://gtalug.org/meeting/2021-04/> # Windows subsystem for linux with Evan Leibovitch After one too many times fighting with PulseAudio and video drivers and having printers and scanners that will NEVER work with Linux, I gave up my dual boot laptop and desktop and have loaded Win 10 on both. Turns out, things run faster too, even open source apps like Handbrake which take advantage of the GPU to do its video decoding while Linux can't do that. But the story is not done. I installed Windows Subsystem for Linux and now have a fully running Kubuntu as a VM when I want it. And there are some interesting tools such as Windows Terminal in which you can have a Linux terminal shell next to a tab with Windows PowerShell. # Lightning talks This is GTALUG's version of an un-conference, a loosely structured short talks emphasizing the informal exchange of information and ideas between participants, rather than following a conventionally structured GTALUG meetings. If you already have a topic in mind please send an email to speakers(a)gtalug.org to be added to the list of scheduled talks. ## Location Join Zoom Meeting: https://us02web.zoom.us/j/84001023881?pwd=Tk9DNnB0OXZibTJUT2hUR2taeGY2dz09 Meeting ID: 840 0102 3881 Passcode: 688539 Find your local number: https://us02web.zoom.us/u/kdNFVrX48s ## Schedule * 7:30 pm - Meeting and presentation. # Code of Conduct We want a productive happy community that can welcome new ideas, improve every process every year, and foster collaboration between individuals with differing needs, interests and skills. We gain strength from diversity, and actively seek participation from those who enhance it. This code of conduct exists to ensure that diverse groups collaborate to mutual advantage and enjoyment. We will challenge prejudice that could jeopardise the participation of any person in the community. The Code of Conduct governs how we behave in public or in private whenever the Linux community will be judged by our actions. We expect it to be honoured by everyone who represents the community officially or informally, claims affiliation or participates directly. It applies to activities online or offline. We invite anybody to participate. Our community is open. Please read more about the GTALUG Code of Conduct here: https://gtalug.org/about/code-of-conduct/. If you have any questions, comments, or concerns about the GTALUG Code of Conduct please contact the GTALUG Board @ board(a)gtalug.org. --- GTALUG Announce mailing list announce(a)gtalug.org https://gtalug.org/mailman/listinfo/announce
