Re: Microsoft PowerShell

Snaps (https://snapcraft.io/) are an application-packaging technology created by Canonical designed to be developer-friendly by including dependencies instead of breaking them up into smaller packages like deb and rpm formats do. Personally I don't think think Snappy is very well designed, but as long as they lower the barrier of entry for application distribution on desktop Linux then it's a net positive.

It might just be that your disk is dying, or has bad blocks. I'd boot off a rescue image and do a 'badblocks' scan of the disk and see what pops up. Good luck! John

Re: Full Home folder

by Steven Greenberg

Here is my diary entry for the solution I found when I had problems like this. 01 Sep 2017 Today's Contents Linux <#01Sep2017Linux> Back to Table Of Contents <#TableOfContents> Linux .xsession-errors is still causing problems. Xserver - X Window System display server <https://www.x.org/archive/X11R6.8.0/doc/Xserver.1.html>. Perhaps the audit level has been mis-set. Should be level 1. Can't figure out if it is set, or where it is set. Interesting file to look at is/var/log/Xorg.0.log. Using config file /etc/Xaa/xorg.conf. Maybe I should be looking at kde. Huge .xsession-errors <https://ubuntuforums.org/showthread.php?t=1517991>. Here is one suggestion. Had the same problem with 11GB .xsession-errors. Fixed it with a solution I found to disable the recent history too. rm .xsession-errors touch .xsession-errors sudo chattr -i .xsession-errors Simply delete the file. Create an empty file. Set the immutable attribute. Which makes the file protected against writing and deleting. Nothing can be logged. Note that until you logout the file space deleted is not unallocated because the file is being held open. I did it. If I break X when I reboot, then I don't know what I will do. 38: rm -f .xsession-errors 39: touch .xsession-errors 40: lsattr .xsession-errors -------------e-- .xsession-errors 41: sudo chattr -i .xsession-errors [sudo] password for steve: 42: lsattr .xsession-errors -------------e-- .xsession-errors 43: sudo chattr +i .xsession-errors 44: lsattr .xsession-errors ----i--------e-- .xsession-errors 45: rm .xsession-errors rm: remove write-protected regular empty file '.xsession-errors'? n I rebooted, and I think it worked. 6: lsof -nP | grep 'deleted' 7: df Filesystem 1K-blocks Used Available Use% Mounted on /dev/sda1 19478204 16789308 1676416 91% / 9: dir -l .xsession-errors -rw-rw-r-- 1 steve steve 0 Sep 1 22:47 .xsession-errors 10: lsattr .xsession-errors ----i--------e-- .xsession-errors The following is from the man page ofchattr. A file with the 'i' attribute cannot be modified: it cannot be deleted or renamed, no link can be created to this file and no data can be written to the file. Only the superuser or a process possessing the CAP_LINUX_IMMUTABLE capability can set or clear this attribute.

Tonight's meeting

by rich＠richardklein.org

I've never been to a WLUG meeting before. It's okay for a member of the general public to just show up, right? On a different note, I was trying to set up the Cyrus mail server under Suse 9.2 and have been having a hell of a time with it. I set it aside about 2 weeks ago and haven't gotten back to it. If I bring the PC with me, would anyone be able and willing to help me configure Cyrus properly (or maybe the problem's with PAM - I don't know)? I suppose I could set it up at home for someone to access via VNC or something, too. Thanks, -- Rich

Please use only the new list address wlug(a)lists.wlug.org to post--if you use an old address you'll get a reminder to use the new one, at least until a few weeks from now when the old server will have to go offline. I'd also like to thank our generous host http://mailman3.com for providing our new mailing list and Hyperkitty web forum free of charge.

IMPORTANT: Upcoming WLUG Mailing List Move

by Chuck Anderson

After 18+ years of the WLUG mailing list being graciously hosted on the WPI campus network at no cost to WLUG, we must move to an external mailing list host as WPI prepares to shut down its Linux email infrastructure after moving to Microsoft Office 365 in the cloud. Phase 1 begins Monday, July 23, 2018, but the shutdown for third-party domains like wlug.org is planned for mid- to late-August. Luckily, we have a new sponsor who has generously offered to host our mailing list at no cost on Mailman 3 with Hyperkitty! We are currently setting up the new mailing list and working out the details, but I wanted to send out a "heads up" message to everyone before anything changes. The plan is to set up the new host in parallel with the existing host, but this necessitates a change in the mailing list address. I also plan to copy the existing subscriber list (and archives if possible) over to the new list, but if that isn't possible I'll let everyone know. More details will be coming soon. I'll also update the WLUG website http://www.wlug.org/ with the new mailing list details when we are ready, so watch that space in case we lose the ability to send to the old list! Worst case, we have the subscriber list backed up and could send an email to everyone individually if it becomes necessary. Thanks, Chuck

TinyArcade and Arduboy

by Dennis Payne

I've been playing around with the Tiny Arcade by Tiny Circuits. It's been a lot of fun programming. The initial development of Color Monster is documented here: http://identicalsoftware.com/games/colormonster The new Pocket Arcade has me really interested but it isn't available yet. I stumbled across the Arduboy. (Stumbled again? I'm pretty sure I saw the kickstarter and decided against it.) Does anyone have one? What do they think of it? I think it isn't quite what I want for a system. Seems like it can be annoying to upload a new game onto the system. While I had fun with the TinyScreen Video Game Kit, I like the microsd card of the Tiny Arcade so you can have multiple games available.

UPS power backup unit needs home

by E Johnson

I have a UPS power backup unit here that I can't use. This is a Cyber Power model 1000PFCLCD. This should supply around 15 minutes of power to your computer & peripherals in the event of a power outage. Enough time to shutdown your delicate operations properly, save the doc you were just working on, or put your game on pause... Purchased several years ago (for around $109), I never used it in the old place because NONE of the circuits were grounded --so it wouldn't ever do anything. Now in the new place, nothing is grounded here either! Probably it works but I was never able to test it, since it requires a grounded circuit even to charge itself. It has not been abused except by a little dust. This is about the size of eight bricks all stacked together into a box shape... Probably heavier than eight bricks. Unscented; smoke- & cat-free. Will go with your other shiny black computer decor. Someone needs this! I want you to want this! Offering it here first, FREE to good home. I am still in Worcester, now on the quieter end of Vernon St. Pickup time flexible, and we have an off-street spot where you can temporarily park. Who wants this? Let me know. Liz J

Reminder! Meeting July 12th 2017 Topic: Open Forum / BBQ / guix

by Tim Keller

Hey Gang, Our next meeting is July 12th, 2018. Currently there isn't a topic, so I think I'm going to call this an open forum meeting. There was some talk about guix, so we'll definitely be talking about that. We'll also talk about when we want the BBQ. Personally, my vote is for Sept. Less bugs, cooler weather, etc. Obviously if someone with a pool wants to pitch for August I can be persuaded! Location: WPI Campus Center Rm 301 (Hagglund room) When you come up the stairs go right instead of left. Refreshments and snacks will be provided. Afterwards we'll head off for dinner and keep up the conversation. Later, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".
