I think stock Linux Mint is still on 4.15.

mailing list issues

by Anderson, Charles R

Some people (including myself) have not been receiving emails sent to the list. I'm guessing that DMARC may be blocking messages from senders' domains that have DMARC set up, so I made a MailMan change to enable DMARC Mitigations. This works by replacing your "From: you(a)wherever.com" with "From: Your Full Name via WLUG <wlug(a)lists.wlug.org>". Your original From: appears in the Reply-To: header. I'm also sending this message to test delivery to a few domains like yahoo.com and gmail.com.

If it is 4.19.x, you may have have hit a data corruption bug in Linux's block layer: https://www.phoronix.com/scan.php?page=news_item&px=Linux-4.19-EXT4-Issue-L… My suggestion--rollback to 4.18.x until this is all resolved.

desktop (linux Mint/ubuntu) Motherboard/sata/grub fun

by Doug Mildram

Warning: there's a couple "fun" ( aka "new to me") things in this LONG email. SUMMARY 2-lines-below: 1) on reboot, an initramfs prompt, errors only seen briefly as boot screen overwrites it. Needed fsck. 2) later when things got worse, my solution followed by a different error message re: "environment block too small". the LONG story: Months ago i managed to move wife/maureen's desktop environment to Mint(ubuntu underneath). Usage: firefox,gmail (almost nothing else of note. This took some persuading, but desktops are such a fallback these days......another topic for another day) DESKTOP: 10?yr-old Gigabyte motherboard with sata2/sataII ... 4 ports. I only use 1 sata port. I "gave" it a $90/bestbuy 256g SSD Samsung months ago for /dev/sda which ran well+fast of course, turns out the SSD is actually still fine internally. A FEW WEEKS AGO, the "hint" symptom (1 of 2 in this long story) for disk woes was.... ( it started crashing occasionally, then) ON BOOT, it would sometimes STOP at this prompt initramfs> and with good eyes as the boot-attempt screen(s) would fly by and return to above prompt, I discovered I could fix it with ( actually i did not use the "-y" prompt, but it's the same fix either way) initramfs> fsck -y /dev/sda1 Which worked every time (a few times), nothing scary for an ex-unix-sysadmin, followed by initramfs> exit ######## would allow it to boot and be OK for days or so. I taped THAT magic (fsck...) onto a paper mini-sign on the PC for another rainy day. TODAY, the crash was followed by not booting (random results, kernel panics or bios/grub waiting). So I brought the SSD to my other living room desktop (not booting FROM it...) checked SSD with sudo smartcl -a /dev/sda #### AND ITS FINE. I moved the SSD "back" to wife's PC on another SATA port. It's fine! (motherboard deteriorating i guess....but might last another decade). I did run into.... ("created" by moving the disk i assume) .... a boot/warning error NEW TO ME: On initial boot a WARNING ERROR on the early/black screen (similar to where initramfs> shows up..just before that i think) "warning: environment block too small" was actually ignorable (after a few secs, boot marched on to kernel/logo). But I found "it's a thing" and the error appears solvable with first google hit suggesting linux user# sudo rm /boot/grub/grubenv # or "mv" it somewhere.old; 1024 byte file. ...............# sudo grub-editenv /boot/grub/grubenv create and reboot. Seems good now except (new i think; probably from the sata port move?) there's a ONE MINUTE wait on the initial boot with the Mint logo flashing. Final things-to-inspect: (no need to "fix" /etc/fstab which of course does find the disk parts ( just / and swap) by UUID and /var/log/syslog ( I have exportedthe old history to study, i think the disk errors stopped. ) =========================WRAPUP Haven't solved this learn-all mission yet, but...hope to make it to WLUG THURS EVE and i just thought of a (this) topic. Trick is knowing where to start such a story/tutorial; I'd try to skip over BIOS and sata/disk/etc basics, the fuzzy parts for me involve "initramfs" ... grub ..... and maybe that's it for me. Desired talk/take-home: linux BOOT steps you don't want to know. -doug

WLUG meeting this week

by Anderson, Charles R

I haven't seen any messages to the list since November 8, so I'm sending this message to see if the mailing list still works. We have a WLUG meeting scheduled for this Thursday at 7pm in the WPI Campus Center, Mid-Century Room (the location we use most often).

desktop (wife=moved->linux Mint) MB/sata/grub fun

Warning: there's a couple "fun" ( my definition for "new to me") errors/areas in this LONG email. Months ago i managed to move wife/maureen's desktop environment to Mint(ubuntu underneath). Usage: firefox,gmail (almost nothing else of note.

I taped THAT magic (fsck...) onto a paper mini-sign on the PC for another rainy day. TODAY, the crash was followed by not booting (random results, kernel panics or bios/grub waiting). Worse (not that we care!) near the end of this story, the Patriots gave up cool kickoff return with a lead and 0:04 left. But timing-wise, I'm glad I had a few hours in the living room to debug all this. So I brought the SSD to my other living room desktop (not booting FROM it...) checked SSD with sudo smartcl -a /dev/sda #### AND ITS FINE. I moved the SSD "back" to wife's PC on another SATA port.

December Meeting Reminder!

by Tim Keller

Hey Gang, We've got a meeting coming up next week! Date: Dec 13, 2018 @ 7PM. Location: WPI Campus Center (Mid Century Room 331) Topic: To Be Decided! If there's something you'd like to talk about drop me a line! Otherwise As usual, refreshments and snacks will be provided and we'll head off for dinner afterwards. Thanks, Tim. -- I am leery of the allegiances of any politician who refers to their constituents as "consumers".

OpenGameArt Movie Video Game

by Dennis Payne

Normally I do National Novel Writing Month in November. This year I decided to try the Indie Game Making Contest 2018. I spent the month working in my free time on a new computer game. I had thought of this game a while ago (including doing a novelization of it for NaNoWriMo last year). The idea was to use lots of art from OpenGameArt.org. Since the styles of the artwork can be drastically different, that was integrated into the story. The villain is in the Liberated Pixel Cup style. (It was a contest opengameart.org did to create lot of artwork which could be used together.) He would be trying to wipe out all the other art styles. (It's a crazy mashup like the Lego Movie.) The game didn't get to the level of completion I had hoped. I posted a Postmortem on the project: http://identicalsoftware.com/games/opengameartmovie You download the Windows version of the game from: https://dulsi.itch.io/opengameart-movie-video-game Unfortunately there isn't a log of content in the game as much of the work was building the game engine. (Why isn't there a Linux download? I was rushing to post it before the contest end and didn't get around to posting a Linux build. We aren't allowed to put up new downloads while the judging is being done.) -- Dennis Payne <dulsi(a)identicalsoftware.com>

Frantic last minute room change

by thinkbrown＠gmail.com

Hey WLUG! Frantic last minute change of room. Due to the relative inaccessibility of Stratton after 5PM, we moved to Campus Center room 128 (the Taylor Room). This is on the first floor (down the stairs through the main entrance). Sorry for the last minute notice Logan (pretending to be Tim)
