Comparing distro packages
by Dennis Payne Aug. 13, 2019

Aug. 13, 2019

I wanted to know if OpenAlchemist is included in Debian. During my searching I found distrowatch has the ability to compare packages from distributions. I pull up Fedora and Debian. https://distrowatch.com/dwres.php?resource=compare-packages&firstlist=fedor… Fedora's list of packages doesn't include OpenAlchemist. Nor does it include shippy, ostrichriders, and btbuilder. Clearly this isn't a complete list. Am I doing something wrong on distrowatch? Is there a different way to do the same thing?

Do I need a webcam app that specifically supports gspca? Anyway, I added myself to the 'video' group and ran Cheese. Since I was already in the terminal, I ran Cheese from the command line instead of from the GUI, like I usually do, and I was rewarded with some extra output (editing out some irrelevant lines): > Xlib: extension "RANDR" missing on display ":0". > (cheese:8484): cheese-CRITICAL **: 10:26:20.051: cheese_camera_device_get_name: assertion 'CHEESE_IS_CAMERA_DEVICE (device)' failed Cheese still didn't find a video device, and I got the same results running it as root.

Best place to look for webcam drivers
by Richard Klein Aug. 7, 2019

Aug. 7, 2019

I picked up a Creative Labs model VF0250 webcam, but V4L isn't detecting any devices. I googled it and it looks like gspca supported this model, but it also looks like gspca was abandoned years ago. Where would you look for answers? BTW, this is for Mint.

WLUG Meeting July 18th 2019 NOTE: Location Change: WPI Campus Center: Morgan Room
by Tim Keller July 16, 2019

July 16, 2019

Hey Everybody! We've got a meeting this Thursday July 18th at 7PM! Location: WPI Campus Center: Morgan Room (main floor hallway to the left of the front desk) Topic: Pi 4 I thought we might talk about the pi 4. I'm going to grab the 1GB version so we'll have a sample device to poke at. I'd really like the 4GB version, but those are a bit hard to find.. I'll have it, plus a pi 3 and an assortment of older pi's as well. As usual snacks and refreshments will be provided and we'll head off for dinner to continue to the conversation. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Next Meeting moved to July 18th 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".
