Thanks for a great meeting last night!
by Tim Keller 26 Sep '19

26 Sep '19

As usual at WLUG, we went off on a tangent and it was amazing.. What started out as a side conversation about storage technologies turned into 1.5 hour conversation about LVM / ZFS on Linux / Ceph / GlusterFS / Synology / FreeNAS / NetAPP and the general philosophies around managing scalable storage at home and in the enterprise! This conversation continued at the Boynton and was great fun! Next meeting is the 10th of October! Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Becoming a brick-and-mortar Linux vendor
by Joshua Stone 25 Sep '19

25 Sep '19

Hey everyone, I'm sure we all know how successful Linux is across different markets today, but I've been wondering about with Linux as a desktop platform if one were to run a business around selling machines that're built with it in mind. The market for online retailers selling devices shipping Linux already seems diverse enough, but I don't know of any successful brick-and- mortar stores selling these devices. I think there could be some advantages to this, including: - Spreading awareness about Linux and the FOSS community - Providing on-site troubleshooting and consultation - Demonstrating different form factors such as Raspberry Pi, Steam OS machines, workstation etc - Providing a physical location for workshops, LUGs, and other meetups - Having a one-stop shop for hardware that's already known to work on Linux such as USB DACs, wifi adapters, etc - Generally act as a community center for computer enthusiasts - Partnering with pre-existing online vendors so customers can test their hardware in-store Jumping into a business such as this does sound risky though, seeing as the Linux crowd is generally very hands-on about computers they purchase and are willing to fix problems on their own. There are also many hurdles that the ecosystem has to catch up on in order to be competitive with applications found only on Windows and/or macOS. That being said, I think I'm still curious to see how much interest there would be in selling a platform around desktop Linux in a brick-and- mortar store with an experience similar to Microsoft and Apple stores. It would certainly help for attracting new users with a more integrated approach that we've come to expect from other platforms, and I think we're in a pretty good position these days for seeing growth. I'd also like to say that I have no experience in marketing, so I wouldn't know where to start with doing anything like market research or studies, so I'm eager to hear any suggestions for how to gauge the potential for a business idea such as this. More than happy to hear what everyone else thinks! Sincerely, -Josh

September WLUG Meeting Announcement!
by Tim Keller 05 Sep '19

05 Sep '19

Hey Everybody, We've got a meeting next week! Date: September 12, 2019 Time: 7pm Location: WPI Campus Center Mid-Century Room (rm 331) aka. the usual haunt Topic: Tinkercad codeblocks and more! I know that a few of us have tinkered with and enjoy using OpenSCAD. However, for many users the learning curve is REALLY steep and this steep learning curve has kept many users away from programmatic shape generation for 3d modeling. Basically writing code to generate a shape. At our last meeting Frank Sweetser showed off something really cool, which is that Tinkercad has now integrated a "scratch" like language into Tinkercad. At this meeting someone will be giving a demo of this. I think we would be remiss if we didn't talk about exFAT and Microsoft's decision to open the patents on it. It *sounds* like we may have exFAT becoming a first class citizen on linux. Is this Microsoft playing some long game of embrace, extend, extinguish or are we moving towards some wild convergence point? In that is the interesting conversation where we think linux will be in another ten years and for that matter Microsoft. As usual, snacks and refreshments will be provided and afterwards we'll head off for dinner and fall deeper down the rabbit hole! Later, Tim. WLUG President -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Comparing distro packages
by Dennis Payne 13 Aug '19

13 Aug '19

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?

Best place to look for webcam drivers
by Richard Klein 07 Aug '19

07 Aug '19

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.

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.

03 Jul '19

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.

Dual GPU Laptops Experience?
by Dennis Payne 28 Jun '19

28 Jun '19

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 13 Jun '19

13 Jun '19

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!

Setting up new monitor
by Richard Klein 30 May '19

30 May '19

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 21 May '19

21 May '19

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
