You-Do-It Electronics is dead, long live You-Do-It Electronics

You-Do-It Electronics went out of business. It was a very nice resource. Does anyone know of a similar electronics store that is within a 1 hour drive of Woosta? -David

Seeking Ubuntu Help
by gmcaplan＠gmcaplan.org July 2, 2024

July 2, 2024

I hope one or more of you can help me. I upgraded today from Ubuntu 18.04 LTS to 20.04 LTS on my desktop computer. (I know I am way behind, but I can do this only in the summer etc., etc.) I used the built-in Ubuntu update feature. It worked better than I expected and took less that two hours. The data backups I did ahead of time took much longer. Anyway, 20.04 is running but I have two problems. Number One: Many terminal commands give this message: Errors were encountered while processing: linux-image-4.15.0-212-generic Processing was halted because there were too many errors. W: Can not find PkgVer for 'linux-image-extra-4.4.0-122-generic' E: Sub-process /usr/bin/dpkg returned an error code (1) In particular, here is what happens when I try to remove 4.4.0-212. sudo apt-get --purge remove linux-image-extra-4.4.0-212-generic Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package linux-image-extra-4.4.0-212-generic E: Couldn't find any package by glob 'linux-image-extra-4.4.0-212-generic' E: Couldn't find any package by regex 'linux-image-extra-4.4.0-212-generic' Number Two: I cannot get audio out of Line Out to my speakers. And I cannot get audio into Line In to make recordings. I *do* get audio from the audio output on my HDMI monitor. This might be related to the need for codecs, but when I try various terminal commands to load more codecs, I get problem Number 1 ! Some of what I read on the Web mentions tex files that could cause Number 1. I do have TeXstudio installed. I tried to uninstall texstudio and texlive, but when I do that, I get the message ant Number One! I'd appreciate any help or suggestions. Thank you.

Reminder: Meeting June 13th 2024 at 7PM! Topic: Your own personal LLM!
by Tim Keller June 21, 2024

June 21, 2024

Hey Gang! We've got a meeting tomorrow!! Date/Time: June 13th 2024 @ 7pm. Location: Technocopia, 44 Portland St, 6th floor, Worcester MA. Virtual Location: (back to the old haunt) https://meet.jit.si/WlugMA <https://meet.jit.si/WlugMA> Considering how much AI has been in the news, I thought it would be cool to do a talk/demo about setting up your own personal Large Language Model! I'll either use my laptop of scrounge up a piece of good enough hardware to show it off.. hell I could even spin up a droplet and run it somewhere.. we'll figure that out. Jansen sent me some links to the cool stuff he uses and I'll definitely be leaning on his expertise and others. Here's what he wrote: the self-hosted webui i use is here: https://github.com/open-webui/open-webui ollama! https://github.com/ollama/ollama here's the docker for ollama: https://hub.docker.com/r/ollama/ollama I've experimented with the ollama models and they're cool. As usual we'll nerd out, wrestle with some LLM stuff and have a great time. Afterwards we'll head off to the Boyton or somewhere else for some dinner and keep the geekery in full swing. I'll bring some snacks and refreshments as well. Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Re: Hierarchical note taking, Joplin, Trilium, browser extensions, etc..
by Tim Keller June 4, 2024

June 4, 2024

Sadly no. I've looked at DokuWiki a couple of times. The problem is this. I'm lazy. The lowest barrier to entry is simply a directory called "Notes" with a bunch of text files. Being text and using a unix-like system, I've got tools like grep to find stuff. I figure the next lowest thing is some program that lets me take notes that I can then organize into some index and search against it as well. Beyond that now it becomes hosted somewhere, etc. Tim.

Next WLUG meeting proposal
by John Stoffel May 6, 2024

May 6, 2024

Guys, Tim & I both have conflicts on alot of Thursdays in May for the regular WLUG meeting. We'd like to see how people feel about moving it to either May 8th or May 15th instead this month. We're still checking with Technocopia to make sure we will have access on either of those days, but we wanted to reach out and make sure the rest of you are ok with this change. Thanks, John (and sorta Tim)

Great meeting last night!
by Tim Keller April 17, 2024

April 17, 2024

Having our own Jitsi instance was fantastic! Jansen got into ollama AI stuff and it was really cool. He's expressed interest in doing a full end to end demo. We talked about the xz explot and it's entanglement with systemd and OpenSSH. It was a great conversation about the history and missteps of systemd and how we got to this place where so many pieces of critical software in the FOSS are supported by just a few people. Next month's meeting will need to be moved around as it conflicts with something, I'll give more details as I learn them.

Does you meeting > start at 7:30? I assumed that the meeting starts at 7:00. I connected to https://jitsi.uvhash.org/WlugMA (no %20uvhash) at 7:00 and found people there. Does jitsi create rooms upon demand from anyone? My problem was that, while I could hear other people (at least while they were near the microphone and the gloppita-gloppita machine was off) they could not hear me, except intermittently. Worse, it seemed that my laptop was generating noise and feedback, so people had to mute me so that they could hear each other. The problem seemed to be in the software or configuration of my Thinpad with Debian GNU/Linux 12 (bookworm) and Firefox ESR 102.15.1 of Sept 12, 2023. I thought I had tested it the day before. I found a way to make a recording and recorded a short speech, which I could play back. It all seemed to work, but when I unplugged it and plugged it back in it required reconfiguration and I may have missed something and wound up using the built-in mike. The same USB headphone/mike seemed to work when attached to a Windows machine, but where's the fun in that? I checked out early in disgust. Suggestions on how to debug the mike might be helpful. -- Keith _______________________________________________ WLUG mailing list -- wlug(a)lists.wlug.org To unsubscribe send an email to wlug-leave(a)lists.wlug.org Create Account: https://wlug.mailman3.com/accounts/signup/ Change Settings: https://wlug.mailman3.com/postorius/lists/wlug.lists.wlug.org/ Web Forum/Archive: https://wlug.mailman3.com/hyperkitty/list/wlug@lists.wlug.org/message/OA5FC…

Hey Gang, In an effort to actually eat our own cooking, I've stood up a Jitsi server for us to use. Physical location: Technocopia, 44 Portland st. Worcester MA The NEW VIRTUAL LOCATION: https://jitsi.uvhash.org/WlugMA Time: 7pm Date: Today! April 11th, 2024 Topic: We'll talk about the xz backdoor attempt, other linux related security stuff, How dead easy it was to self host jitsi, other hosting stuff likely, etc. As usual, I'm sure the conversation will wander, get really interesting and it'll be a blast.

Hey Everybody! We've got a meeting next week! I think it's really worth talking about Self hosting. It's come up a couple of times, I think it's worth talking about what the options are, what they might cost and what can be hosted both using on prem hardware and your own cloud instances, options for networking, etc. I'd like people's ideas, caveats, etc. What have people hosted?

Meeting Tonight, March 14th 2024. Topic: "self hosting"
by Tim Keller March 14, 2024

March 14, 2024

Time: 7pm. Date: March 14th 2024 Location: Technocopia 44 Portland St. Worcester MA. Virtual Location: hopefully hosted independently, but at https://meet.jit.si/WlugMA For now.. We are increasingly living in a world where our data isn't ours anymore. Everything is a service being hosted by some entity, subjected to the whims of that entity. Come to love some service? They're discontinuing it. Your data? They're using it to train some AI that you don't control. Functionality? Ever changing.. Costs? To change without warning and your data is now hostage. To that end.. What are people doing? What would people like to do? What options are out there? What's worked in the past and now doesn't? There's also SOAF "significant other acceptance factor" to consider.. If you own the data but it's so horrific to manage that it sends everybody around you fleeing back to some service, that's no good either. I expect this to be a pretty lively debate. As usual, we'll head out for dinner and continue the conversation. I'll have snacks and refreshments available. Thanks, Tim.

fun crashing and burning in Google Earth Pro's Flight Simulator
by Doug Mildram March 13, 2024

March 13, 2024

Hey all (from doug in the boonies, retired = too much time on my hands) Brief my-nonexistent-skills-history: I've avoided fun/gaming on computers/screens forever. Well, ~ 1997 I bought a joystick and a couple windows games. Lost the joystick, but probably wouldn't help me in flight...? I did better with the 1990's era MS Excel97? magic escape to flight simulator that easily flew me on the moon, to a monolith. Fast forward to now. While looking for my town's GIS tax maps, (which I never found, just PDF's w/ lot lines, no owner names, no tax $info. Every town is different.) Then, under clueless town "Tax Maps" webpage, I found this note: *Please note*: Parcel boundaries are intended to be used for the purpose of property assessment and should not be considered survey accurate. You will need to have Google Earth <http://earth.google.com/> installed to view this data. For help using Google Earth go to the Help Center..... and forget all about tax maps ( I added that here-doug) doug> I got Earth help, yes! I have no joystick, so keyboard and mouse. Pardon doublespacing below. Some copy/paste's do odd things for my gmail edits (now I'm in tiny font in a battle to un-do the big effect of the above paste :) Stumbled into install cmds for google EARTH PRO (free), worked on Linux Mint20. 1) wget https://dl.google.com/dl/earth/client/current/google-earth-pro-stable_curre… (result: GOT a 58mb file named google-earth-pro-stable_current_amd64.deb) 2) sudo dpkg -i google-earth-pro-stable_current_amd64.deb (output: Preparing to unpack google-earth-pro-stable_current_amd64.deb ... Unpacking google-earth-pro-stable (7.3.6.9796-r0) ... Setting up google-earth-pro-stable (7.3.6.9796-r0) ... Processing triggers for man-db (2.9.1-1) ... Processing triggers for desktop-file-utils (0.24+linuxmint1) ... Processing triggers for mime-support (3.64ubuntu1) ... (DONE). LAUNCH TO OUTER SPACE: 3) $ google-earth-pro If you see a few continents from space, good but here's the fun: ========First zoom to somewhere you know, use upper LH Search, enter your address or fun place. Adjust eyes, or ignore briefly, fuzzy view of map,streets,trees,whatever. The fuzziness disappears or changes, if you enter Flight Simulator from here. ==== PULL DOWN MENU for "Tools" has "Enter Flight Simulator". Choose the slower plane, not the F-16 jet if you suck like I do. The mouse now flies the plane. I want to skim over my hood. I use my four arrow keys , mouse-moves work too but I flip out. I know I'm missing some kind of flight/plane control, should RTFM. I thought Flaps controlled pitch/up/down, but my Flaps stay at 40% and I crash in hilarious various mistakes every minute or so. What fun! Resume Flight brings all control back so off you go to die again.... I'll try to shut up now and find out if any of you already mastered? this. Lots cheaper than a drone! Fast, Cheap, Good.... all 3? --doug
