For a long time I was using NX (or FreeNX) on my work desktop so I could connect between a windows box and a linux desktop using Synergy to map the keyboard/mouse between systems as I moved the mouse between my desktops. That was using the 'nomachine.com' software, though I used the freenx stuff. But after a while it got to be too painful, and now that I mostly work on a windows laptop for work (due to the work VPN requirements) I don't tend to do anything beyond lots of putty sessions in which I run screen. I've tried MobaXterm, but never really liked it, even though it does offer native X display, so you can fire up remote graphical tools. This would work better if I wasnt' 80-100 miliseconds of lag (basically across the entire US) distant from the remote systems I manage and work on. Much as I hate to say it, I've sometimes just fallen back to VNC when I need to fire up a web browser to download a 5-10gb ISO image to do a system install.

I'll definitely try this out. It would be nice if the windows client also supported these options as well at times. Cheers! Joohn

Mojotron: Robot Wars

by Dennis Payne

Mojotron is a twin stick shooter similar to Robotron: 2084 or Llamatron. I've been redoing the graphics and fixing up the game. I decided to make a trailer to promote the game. The source code for my update has not been released yet. https://youtu.be/LBEphj6g04c I used Pitivi to create this and another video. The program has gotten a lot better. I no longer have to save after each change because of how often it used to crash. -- Dennis Payne dulsi(a)identicalsoftware.com https://mastodon.gamedev.place/@dulsi

Last meeting mention of connecting to DISPLAY :0

by Chris (wolcen) Thompson

Hi all, Great to see you all in the last meeting :-) I was the skateboarder...who caught me almost falling shortly before I left? LOL ----------- Remote X [Insert name I've forgotten here (sorry!)] mentioned that their users connect to a remote session's root desktop (or whatever you call the initial/primary display :0 deal that you initially/locally get). I would like to do this as well. SSH with port forwarding is probably my preference, but wireguard would be OK as well. I don't think I want to directly expose anything like xrdp. Anyway - could you please refresh my memory as to what was being used? I'm running i3 in this case (started via lightdm). I generally have not loved using VNC-based tools, but if that's what is currently recommended, I guess I'll give it another go. ------------ SSHFS Optimization Also - I referred to using sshfs internally for myself to my NAS, and some optimizations for it. This is my current alias to mount it: sshfs -o cache=yes -o kernel_cache -o Ciphers=aes128-ctr -o Compression=no -o ServerAliveCountMax=3 -o ServerAliveInterval=15 -o reconnect -C -o idmap=user server: /mymountpoint I got a few of the recommended switches from this article that finally convinced me to just forget about NFS: https://blog.ja-ke.tech/2019/08/27/nas-performance-sshfs-nfs-smb.html Thanks! Chris PS - I used to respond here from an account that was at from a riseup.net account. I have since moved to mailbox.org so it at least 'comes from' wolcen.com...I hate/am terrible at managing email servers. Anyway: all those responses/posts therefore were moderated. I'm not sure ANY of those ever made it though, so I was curious if anyone does any checks on moderated messages?

Free lab bench

Hi guys, Looking to get rid of an 8’l by 30” deep by 36” high lab bench. See pictures. You will have to come get it but I will help take it apart to fit in/on your vehicle. Could be convinced to deliver if you come and help load it on my car. It’s totally free!

They're looking to hire a mechanical engineer where I work, and talking about how a lot of the best candidates have been from WPI.

Re: July WLUG Meeting will be online tonight @7pm

by Chuck Anderson

Suggested topic of discussion: https://comsec.ethz.ch/research/microarch/retbleed/ Retbleed: Arbitrary Speculative Code Execution with Return Instructions Retbleed (CVE-2022-29900 and CVE-2022-29901) is the new addition to the family of speculative execution attacks that exploit branch target injection to leak information, which we call Spectre-BTI. Unlike its siblings, who trigger harmful branch target speculation by exploiting indirect jumps or calls, Retbleed exploits return instructions. This means a great deal, since it undermines some of our current Spectre-BTI defenses.
