From the viewpoint of a jit.si watcher, that was one of the most fun demos of a program I have seen at a WLUG over the decades. But eye-candy aside, I was most interested that the demonstrator claimed to understand how it works and to have some links. The meaning of words changes over time. More change in less time now. A cartoon generating program is called "artificial intelligence". I can't draw cartoons, so I must not be intelligent. The words "machine learning" were used. As I said Thursday, I did my dissertation on machine learning. At that time, it meant a computer (with appropriate programming) would input a sequence of examples, each marked as in or not in a certain class. The computer would then (we hoped) be able to correctly classify examples that had not been explicitly shown before. I didn't see anything like that in the demo. It was said to be based on a "neural net", but neural nets have been around since Minsky started inventing words back in the fifties. What changed to make neural networks suddenly start working? -- Keith

"interesting" KVM currently in my server rack. It's two nonfunctional KVMs kludged together to make one functional KVM with no docs and no monitor. One of the switches only has a functional switch, and one of the switches only has a functional keyboard, with a COTS Dell monitor essentially gaff taped on top. In general though, I'd love to see a list of equipment up for grabs! --cs

I'd love to get one for home for my main server/desktop combo in my basement, but if someone else can really use it, I'm ok with it. And it was great meeting you and I think we had a really fun and interesting talk thursday. Let's try to keep up the fun! Who's up for a talk next month? And does anyone have pointers to the Image generating stuff we talked about? It wiould be fun to try it out myself and for $10 I could get alot of fun. John

That synology is nice, enough grunt to run a fair amount of compute on it.

Heya - fun meeting, cool stuff! I meant to mention, I have a ton (literally) of decommissioned equipment at work we're looking to give/sell/donate away. Mostly Dell, but some other brands mixed in. I may have posted a partial list at some point on the list. A few older servers (R805, R300, two 32-bay Celeros NAS units, Synology RS2416+ with SAS expansion chassis), Optiplex and Precision desktops, a few Precision laptops (that cost us between$4-7K when new), a 16-port KVM, about 30 monitors, keyboards, mice, etc. etc. etc. If you know anyone who needs any more tech to play with, I have it!

Hey Everybody! We've got a meeting tonight! Time: 7pm Date: February 8th, 2024 Location: Technocopia, 44 Portland St. Worcester MA Virtual Location: https://meet.jit.si/WlugMA For a topics, We've got two. Topic #1: Turing Pi 2 hardware Wlug member Zori Babroudi recently bought a Turning Pi 2 and a bunch of Pi and Rocks compute modules. Currently, it's a work in progress, but eventually once things are totally working on it, I'd like to show it off in its full glory. But in the meantime, we can marvel at the hardware. Ultimately, the plan is to run k8s on it and do some LLM based AI stuff as well. Topic #2: ProxMox With BroadCom's purchase and destruction of VMware, many of us are scrambling to look for alternatives to VMware Esxi. One great contender is ProxMox. It's a debian based distro that's focused on providing a great interface to manage vms running on kvm. It also has great support for video card pass through (something I know Brandon is *very* interested in). I've got a 3 node proxmox cluster that I will show off. John Stoffel has also been experimenting with it as well so both of us can talk about the good/bad/ugly of it. As usual, the conversation will be lively and focused around linux, FOSS, fair use and who knows what! Afterwards we'll head off for some dinner and keep the conversation going! I hope to see you there! Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

I'm happy to answer questions and give you example configs. The docs for rsyslog are ok, but sometimes the examples are a little lacking for real world examples.

If you're looking for fully redundant setup, then you might need a load balancer of some sort. It's hard to get complete logging without doing funky things because having a fully redundant setup is nice simple to do right. But also, check your other system configs at the base OS level. And check your VM's bus drivers. Some network cards will have better performance than others.
