(for meeting projectors) laptops,VGA-out,linux....
by Doug Mildram 10 Mar '17

10 Mar '17

doug> Thanks Tim for bringing a functional laptop w/linux for last night's meeting. Our VGA-out projector worked fine as he installed a linux Mint VM (Mate Cinnamon) onto it. When that finished, I wanted to show/compare Mint Mate, which I had already on my laptop. When I unplugged Tim's laptop from VGA-out and tried my own thinkpad running Mint Mate (dualbooted, my alternate OS).....well,.....chirp. The projector stopped projecting. My Fn-F7 key seemed to be trying to cycle thru the blind toggles/choices (Duplicate display? screen-only? VGA-only might expect), but no video came out, I had to give up, not having tried VGA-out ever while running linux on my laptop. We put Tim's back onto VGA-out, and it also seemed dead, but we chose not to fight it, meeting being close enough to stop caring about projector, and it "wasnt a proud moment" for me. SO I WENT HOME and plugged my (same) laptop into my TV's VGA-in port. Started by booting win7. I'd never noticed a detail : at WHICH POINT does this start working....should I expect to see the dualboot/GRUB menu on TV? Apparently not. Soon enough though, Win7 (the OS preinstalled by Lenovo/thinkpad) came up and VGA-out/TV started working as usual. (somewhere AFTER "Resuming Windows", it starts working). To control VGA-out, Fn-F7 works ...I've got (4) choices: Duplicate, Extend(laptop-screen=#1, TV-VGAout=screen2), Projector Only (turns off laptop display), and Disconnect Projector (only laptop display ON). No doubt (i surmise), thanks to windows drivers. Feels like I learned: OS controls VGA-out (somehow naively I was inclined to believe this was more of an OS-independent hardware function). OK, now rebooted laptop/win7 to try Linux Mint from a win7 state with "Duplicate" working. "Shutting down Windows" displayed....laptop goes thru boot/BIOS?...TV is blank now, I've learned to expect this....Linux kernel boots, and I see some of the minimal console text messages as usual ALSO ON TV, laptop-screen AND TV quickly go to graphical mode, also displaying the Mate background... and this is where I was the most surprised. TV/VGA-out appeared "frozen' with the Mate background, appearing much like my laptop screen BUT MINUS anything else (no bottom launch/status/"panel" bar. Whatever I launch on my laptop screen, does not appear on VGA-out. Fascinating! Wed eve late, at my house, I could swear Fn-F7 still wasnt doing anything. But this Thurs AM, it DOES start working a bit (same 4 choices, but blind, and it's strange. TV/VGA-out doesnt show EVERYTHING). I wonder if I'd rebooted at the meeting, would that have helped, probably. Today I play with it some more (ALT-F2 helps when I'm in that semi-blind VGA-out situation, getting SOME things to show on TV) even though I'm not likely to use this feature much?ever? at home, unless I break a leg. Caveat, practice what you bring for meetings to project-OUT! HDMI is also an option in our WPI meeting/conf rms if you have it. ---trivia for Mate interest... (Mate = lightweight alternate to Cinnamon. Their start/launch menus are different, and I can find good stuff in Mate's Control Center.

Reminder! Meeting TONIGHT March 9th, 2017! Topics: KVM, Virtualized windows apps, Linux Mint!
by Tim Keller 09 Mar '17

09 Mar '17

Hey Gang, First the important details! Location: Rm 331 (Hagglund Room) @ 7PM Topic: read below... Tonight we've got a meeting! After the last meeting a couple of people were asking me questions about KVM (Kernel based Virtual Machine). New member Al Reinhart asked me a question about the best ways to run windows apps on linux, either via wine or through KVM / Oracle Virtual Box. He also mentioned Linux.Encoder (the first linux ransomware) which I didn't even know exists. Long time member Doug Mildram also wrote me about Linux Mint. A distribution I know quite well! They'll be some conversation and we'll kick off an install and talk about it's merits as a greate distribution. As usual, there'll be refreshments and snacks and afterwards we'll head to Tech for pizza! Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Tim, Another newbie request. Tomorrow night can you spend a few minutes talking about running Windows apps on Linux, i.e., Wine and virtual machines (my impression is VirtualBox seem to be the most popular). Last month the issue of ransomware came up and the consensus was there is none on Linux. In my wanderings around the web I came across Linux.Encoder as Linux ransomware: https://en.wikipedia.org/wiki/Linux.Encoder.1 Thanks, Al On 03/06/2017 08:55 PM, Tim Keller wrote: > Hey Gang, > > This is a reminder that we've got a meeting March 9th, 2017! > Location: Campus Center Rm 301 (Hagglund Room) > Topic: To Be Decided! > > Honestly, this meeting kind of crept up on me!

WLUG Meeting TONIGHT! Feb. 16th 2017 Rm 331 (Hagglund) iscsi / gfs2 / filesystems / etc!
by Tim Keller 16 Feb '17

16 Feb '17

Hey Gang, Our rescheduled meeting is tonight! Feb 16th @ 7pm. The location is changed a bit, we're going to be in the Hagglund Rm (rm 301) in the student center. Go to the top of the stairs and go to the right instead of left. I'm going to be speaking about storage protocols, ending up on iscsi. I'm then going to talk about gfs2 in particular and then show gfs2 working across two nodes. We're also going to talk in general about filesystems, LVM, partitioning, etc. I expect that latter topic is going to be come a general group topic. There will be snacks and refreshments (coke only) and afterwards we'll head down to Tech Pizza!

Hey Gang! I'm going to be giving a talk about the GFS2 clustering file system. If I can rustle up the hardware I'll give a demo as well. A big part of this will also be about iscsi/iser and setting those up. Here are the details. Date & Time: Feb 9th, 2017 @ 7PM Location: WPI Student Center Mid Century Room (rm 331) I'll bring snacks and refreshments and we'll head out for some pizza afterwards. Thanks, Tim.

I feel compelled to point out now... that the thing I built could best be described as a Lovecraftian horror... a swirling mass of howling mouths and staring eyes...

I'm interested in hesring about GFS, and have been interested since I started compiling my own kernels and saw the option. Talk away!

Next meeting February 9th
by Tim Keller 25 Jan '17

25 Jan '17

Hey Gang, Our next meeting is the 9th! I've been doing some interesting work on the clustering filesystem GFS2 if people would be interested in that... iscsi/iser infiniband using a 100gb file in tmpfs on one machine as a filesystem device on three other machines. So, I can talk cogently about setting up icsi, setting up gfs2 and about tuning such a thing. I also wrote a filesystem testing tool called "death by infinite paper cuts" to iterat I've still got my git methodology slides if people are interested in that as well. I was given a kinect to play with. Though I've got two weeks I might be able to do something interesting with that! Lastly if anybody wants to present on something cool they're working on, let me know! Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

Hey Gang, This is a reminder that there's a WLUG meeting January 17th, 2017! Here's all the vital details! Topic: How To Pick A Single Board Compuer Speaker: Jon "maddog" Hall Time: 7pm Location: Campus Center Room 331 "Mid Century Room" While in the near past there were few choices when it came to "SBC" single board computers, that's not the case anymore. Now there's a whole cornucopia of choices and architectures. Thankfully, Jon "Maddog" Hall is going to get help navigate the myriad of choices. Like always expect his talk to be educational and hilarious! Snacks and refreshments will be provided and as always they'll be pizza down at Tech to continue the conversation. Thanks, Tim. P.S. I'll be unable to attend this meeting due to a prior engagement. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".
