Next Meeting moved to July 18th 2019
by Tim Keller July 3, 2019

July 3, 2019

Hey Gang, I'm moving the meeting down a week since I'll be on vacation next week. The meeting will be on July 18th. I'd love to do a comparison of a pi 4 vs. a pi 3, but buying a 4GB pi 4 is a bit challenging... If someone already has one and could bring it, that would be awesome, if not we'll have to think of a different topic. Yeah, I know you can buy a 1GB/2GB pi 4... but really why would you do that. Thanks, Tim. WLUG President -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Dual GPU Laptops Experience?
by Dennis Payne June 28, 2019

June 28, 2019

I bought my last laptop from System 76. It's worked well but I was thinking of upgrading. I run Fedora so I wiped the Ubuntu installed by System 76 and haven't had any problems. However my current laptop only has the Intel graphics. The new Gazelle, which is closest to what I have, includes Intel and Nvidia. Anybody have any experience with that setup with Fedora and Wayland? Does it work out of the box? Do you need to install System 76 tools to switch between the different chips? Does Nvidia with Nouveau driver give better performance over Intel? I'm unlikely to install Nvidia's closed source driver. -- Dennis Payne dulsi(a)identicalsoftware.com https://social.freegamedev.net/channel/dulsi

Reminder: June WLUG meeting TODAY! Topic: Side Channel Attacks.
by Tim Keller June 13, 2019

June 13, 2019

Hey Everybody, We've got a meeting today, Thursday June 13th at 7PM! Location: WPI Campus Center Mid-Century room (rm 331) aka, the usual haunt. After last meeting we ended up having a side conversation regarding the now multiple side channel attacks that the Intel microarchitecture is vulnerable to. I thought it might be a good time to actually deep dive what these are, why they keep happening, why they're likely to continue and what efforts are being put in to try to mitigate them and the effects these migrations have on performance. As usual snacks and refreshments will be supplied and afterwards we'll head off for dinner to continue the conversation! Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Setting up new monitor
by Richard Klein May 30, 2019

May 30, 2019

I picked up a free monitor today, a Samsung S24C230L. The native resolution is 1920x1080, and it's connected via DVI. The existing monitor has a native resolution of 1680x1050 and is plugged into the analog VGA port. The NVIDIA X Server Settings seem to agree, so what's up with the display on the second monitor? https://photos.app.goo.gl/M1R9MQnDMCaD7qca6 When I try saving the X Configuration File, it warns me that I should use relative positioning for the second display, instead of absolute positioning. Maybe that's the problem, but I can't find that setting anywhere. Got any ideas? -- Rich

PCSX2
by Dennis Payne May 21, 2019

May 21, 2019

Before the meeting on games, I tested pcsx2 thinking maybe I could show it. However, it was removed from rpmfusion in Fedora 30. PCSX2 is playstation 2 emulator. I have a working PS2 but the He-Man game was only released in Europe and it is region locked. The emulator finally allowed me to try the game. Since I didn't like losing that ability I've rebuilt the pcsx2 package for Fedora 30. http://identicalsoftware.com/dulsi/lzma-libs-4.32.7-21.fc30.i686.rpm http://identicalsoftware.com/dulsi/pcsx2-1.4-11.fc30.i686.rpm The src rpms are exactly the same as the files from fedora and rpmfusion. I cheated a bit in compiling the pcsx2 package. It had some errors with system headers files. Rather than create a patch to make it compile, I hacked the system header files. (It was a throw away VM because pcsx2 can't compile in 64 bit.) Feel free to grab it if you want to play PS2 games. -- Dennis Payne dulsi(a)identicalsoftware.com https://social.freegamedev.net/channel/dulsi

Gaming on Linux
by Richard Klein May 18, 2019

May 18, 2019

Does anyone have a favorite tower defense game? Has anyone come across something like World of Tanks for Linux (preferably something that doesn't require WINE or Vulkan)? I was pleased to find Minecraft was in my default repositories. I installed it, but haven't tried it yet. -- Rich

struggling w/ reliable printers on CUPS in small office
by Bradley Noyes May 2, 2019

May 2, 2019

WLug-gers, tl;dr: Can someone recommend a printer (or printer brand) that is reliable for printing via CUPS? I’m struggling w/ printers in a small office and i've struggled to get any kind of guidance on-line. The volume of pages printed at the office is probably around 100 pages a day and there are 4 printers — all HPs and all consumer grade — each printer has its purpose, e.g. there's an 11x17 printer, one color laser, one BW laster, one color inkjet. The office is all iMACs, which connect to a Linux CUPS server. The iMacs were networking directly w/ the printers, but i added the CUPS server to try to mitigate the poor reliability with only marginal results. Routinely printers become “paused” in CUPS so i need to go in and ‘unpause’ them, also some printers just fall of the network entirely. Inevitably the only printer that works most of the time is the ink-jet which is a lot more expensive to re-fill. I’m looking for a reliable solution. If anyone has a recomendation that’d be great! Thanks, — Brad

Reminder: Meeting April 18th. Topic: Open Broadcast System Location: Stratton Hall Rm 106
by Tim Keller April 16, 2019

April 16, 2019

Hey Everybody, This Thursday at 7pm in Stratton Hall rm 106, wlug member Ian Gelman will be doing a talk about the Open Broadcast system. OBS (https://obsproject.com/) is free, open source software that allows you turn your Linux system into a powerful mobile TV studio. If you’ve watched any online content creators in the past couple of years, you’ve likely seen the software in action. In this talk, I’ll be giving an overview of what the software can do, as well as a case study on how OBS helped rocket a simple clementine to the top of the WPI subreddit. ( http://wpiwa.wpi.edu/clementine.html) We’ll finish up with a live demo where we’ll create a stream with some webcam footage, application displays, and an internet radio station. Snacks and Refreshments will be provided and afterwards we'll head off for dinner. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".
