Re: Last meeting mention of connecting to DISPLAY :0

by Chris Thompson

Hi all, Following up on a 6 month or so old inquiry... My request had been to get to my desktop session of X remotely. I seldom use this (mosh is typically more than enough) but occasionally it can be handy - e.g. grabbing a password I forgot to move out from FireFox into KeyPassXC, etc. (I do use FF sync, but not for passwords...call me paranoid - I don't mind). I ended up going with John's suggestion: something VNC-based. While you can set up Xvnc itself for a separate session, I prefer not to do this (nor do I need/want a Display Manager remotely). I only wanted on-demand access to the desktop shown (i.e. what's on the local monitor), and have found TigerVNC to be a good fit for this. Setup... "Client" = laptop on the road, "Server" = the desktop @ home Client setup: while you can use `ssh -L etc.` to set up port forwards, I prefer just using ~/.ssh/config, to which I added something like this: ``` Host my_server # the alias I'm using for the server system LocalForward 5900 127.0.0.1:5900 # forward local port 5900 to 127.0.0.1:5900 on the server site HostName xxx.xxx.xxx.xxx # IP or fqdn of server system ``` So, my laptop's localhost:5900 is now forwarded (through SSH) to the server system's equivalent of 127.0.0.1:5900. You can of course change the ports as needed, but as I do not run an VNC server process on my laptop, this is fine for me. This is where Tiger's*x0vncserver* comes in (*x11vnc* is another alternative). From `man x0vncserver`: x0vncserver is a TigerVNC Server which makes any X display remotely accessible via VNC, TigerVNC or compatible viewers. Unlike Xvnc(1), it does not create a virtual display. Instead, it just shares an existing X server (typically, that one connected to the physical screen). Just what I wanted! Once I have connected via SSH, to the server system, I start vnc on the server with ` x0vncserver -localhost -SecurityTypes none -display=:0`. This only listens on localhost, disabling security, and shares out from display :0, which is my normal i3/X11 desktop. There are a few additional security options with tigervnc, but I'm just relying on SSH in this case. Finally, I connect to my desktop from my client machine with `vncviewer localhost`. You can also just run vncviewer and will be presented with a GUI for specifying options. The performance is ...well, about what I expected from VNC at times, but overall it's been pretty reasonable/good for my limited use cases. A couple notes specific to me that may apply to you: I normally run a picom (an X11 compositor) - killing this before connecting is a good performance choice. Additionally, I disable a monitor with xrandr. The VNC client works well (when in full screen) with multiple displays by scrolling following the mouse motion, but it's just less practical IMO than dropping a monitor. There are some other options that make this set up even simpler (e.g. see the `-via` option of vncviewer), but I figured starting with a more spelled-out example was better.

Re: Intersection of Open Source and Social Change

by Kevin Harrington

Odoo is very FOSS friendly: https://github.com/odoo/odoo I have been mulling over the problem posed by automation and software participating in the labor market alongside people for quite a few years now. I love hearing about localized solutions to problems. The closer people are to the control of what they need to survive, the better. One of the ways to localize control are what David Graeber calls Debt Loops: https://www.youtube.com/watch?v=CZIINXhGDcs Since reading the book hes talking about in the lecture, I have been mulling over how one might make a digital version of gift-economies/debt-loop/auto-jubilee networks. One of the corrosive aspects of markets is the spot transaction. It anonymizes money (something that represents the labor of others owed to you the holder) and encourages us to dehumanize each other into economic means to our ends. Gift loops make each transaction explicitly a public act, and in doing so makes sure that we are confronted with our interdependence on a regular basis. Economically gift economies have the advantage of moving the issuer of credit and debt from a central bank, into the hands of individuals making the decision to trust other individuals and the debt loop system. Those with the ability to express trust in others, and when that trust is reciprocated, then that is the wealth creation engine. When any debt is paid forward until it reaches back to the issuer, the loop is canceled, and all the obligations are unzipped. Therefore one person initiating trust can cancel N nodes in a loop, effectively unlimited. Since it is also fully public, cheating means cheating in public. Beyond the exchange of labor in money or debt interactions, we have a deeper problem of the displacement of the labor market by automation. Beyond the economic arguments, there is a philosophical problem with selling a non-rivalrous commodity and failing to create in the market the demand for said commodity through wage creation. The expected effect of this process would be rising productivity, with stagnant wages as the few jobs remaining are competed for by an ever increasing reserve army of the unemployed. Turns out you can see that in the data as early as the mid 90's. I attached an article I am working on to outline this problem, if you are interested in reading more.

Re: Reminder: Virtual Meeting today at 7PM Topic: Emacs awesomeness.

To your first question, you can get your list of installed packages on Ubuntu by running "apt list --installed" and piping that to a file and copying that off somewhere safe. You'll likely have to strip that file a bit. Then once you've got that file, on your cleanly installed system you can enumerate over that file with a bash for loop and call "apt install *package*" To your second question, I'm sure we've got an R nerd around here..

Re: Reminder: WLUG Meeting tonight: Topic ProxMox / Turning Pi 2

by soup

They began leveraging large language models against... any data set as I understand it. There were a few papers that set the world on fire with their implementations. Academia was raided for questionably sourced corpus for commercial use veiled in community gain. I've been wrenching on stable diffusion API for a few weeks, as a former professional photographer it is shocking to me the quality you can get from very little input and common COTS GPUs. Haven't touched any of the SaaS cloud inferencing services that have come out in this gold rush but they can do quite a lot more with the datacenter class GPU grunt. Text to video (so-called "T2V") is here and getting scary.~ Bless, soup On Tue, Feb 13, 2024 at 4:19 PM Keith Wright via WLUG <wlug(a)lists.wlug.org> wrote: > John Stoffel via WLUG <wlug(a)lists.wlug.org> writes: > > > And does anyone have pointers to the Image generating stuff we talked > > about?

Not too long ago I would have been annoyed by the quote depth of that last message. I'll just take it as an opportunity to reply to several at once.

I didn't know what could be meant by "broken text file", now I see that you mean "broken file processing program". Do you have the source for the geneology program? If not, insert rant here. Does the program crash as soon as you import the file, or only when you do something particular? My first impulse would be to put printf commands into the input procedure. Do you have a spec for what the data is supposed to look like, or is this one of those take-the-money-and-(run|hide|sell updates) programs, whose authors think that's super double secret eye pee? >>>>>>> Sent messages last month asking about the monthly meeting.

I don't reply to questions if I don't know. (Unless a woman asks about a database) I don't think wlug is dead, but I don't know how to schedule a room at WPI. Just a short time ago we were watching robots build robots from source code. Somebody will find the next meeting on a back-up tape. I have a question too, but I'll save it for a another message. -- Keith

Re: [Wlug] OpenWRT on WNDR3800 home router - my install thoughts

by Chuck Anderson

I think this would make a great November 13 meeting topic. We can share our experiences of loading OpenWRT and battling Bufferbloat. I may even get some time this weekend to try loading OpenWRT on my WNDR3700v2.
