Where are the Slides?
by Scott Sullivan 16 Dec '16

16 Dec '16

A common question for any presenter is where can the audience get the slides? GTALUG works with the presenter to make those slides available, when possible. These end up on the Wiki, under the meetings section. https://wiki.gtalug.org/meeting:start With deep audience interest in Peter's talk this month, those slides are now up, and a link to his in depth blog series as well. If you are a past speaker, and would like to send me your slides for inclusion. Please contact me. -- Scott Sullivan w/ GTALUG President Hat

EverNote Alternatives for the Linux User
by Brad Fonseca 15 Dec '16

15 Dec '16

Hello! I'm sure members of this forum have heard of this but I just found out that Evernote has updated their privacy policy (<https://help.evernote.com/hc/en-us/articles/235660588>) to allow "some Evernote employees to exercise oversight of machine learning technologies applied to account content, subject to the limits described below, for the purposes of developing and improving the Evernote service." The notice goes on to say, "While our computer systems do a pretty good job, sometimes a limited amount of human review is simply unavoidable in order to make sure everything is working exactly as it should." (<http://www.computerworld.com/article/3150469/cloud-computing/evernote-chang…>) I was wondering if there are any Linux-friendly alternatives to Evernote that members of this forum would recommend? Ideally, I would want "cloud" access so I can add notes both from an Android app and from a web browser app. There are other features, like image capture, which would be nice but I know that can be replicated in other ways. The caveat would be that my information is encrypted or secured from the issue above. Is this even possible? Thanks, Brad -- Brad Fonseca Mobile: 416-876-2191

The GTALUG Logo: we're looking to update it
by Stewart C. Russell 14 Dec '16

14 Dec '16

Hi - would've loved to join you all tonight, but I got stuck in the east end and can't make it out. At the last GTALUG Operations/Board meeting, the Board decided we really should take a look at redoing the logo. In case you'd forgotten what it looks like, or you didn't know that we had one, here's what it looks like: https://gtalug.org/static/img/gtalug-logo-small.png Apart from some questions over whether we really should be using the official mascot of the Linux kernel for userspace activities, our logo's served us well, but could do with a refresh. So here's what we're looking for in a logo: * something that distinctively captures the spirit of GTALUG: we're in the GTA, and we do Linux … * something that can be reproduced under a Suitable Open Licence; GTALUG may decide to sell things with the logo as a fundraising thing in future, so any *-NC licence shouldn't be used * It would be really nice if we could get this as a vector file so we can laser-engrave/3d print/make colossal sintered chocolate versions/… as is seen fit. We know Linux can scale, so our logo should too. The guidelines: * We can't pay much, if anything, for the new logo. Credit and link for sure. Money we'd have to approve at Board level ahead of time, so please don't work this up at your hourly rate and present us with an invoice. * Send suggestions to me by e-mail, Inkscape-compatible SVG preferred. My e-mail address is *scruss(a)gmail.com* * We'll be running this for at least a couple of months, or until a suitable logo is found * If you're okay with it, we'll put contenders up on the GTALUG wiki for all to see * This is open to all; you don't have to be a GTALUG member * If something is missing from this process, we can discuss it on the list, but submissions should really go off-list to minimize subscriber ire So let's see what you come up with! It's gotta be better than my initial ideas, all of which involved greater-than redirections and lugnuts* … Best Wishes, Stewart *: ‘>🔩’ kinda thing. Yeah, no.

cheap Windows tablets today
by D. Hugh Redelmeier 09 Dec '16

09 Dec '16

The Microsoft Store is selling two Win 10 tablets at a low price today. <https://www.microsoftstore.com/store/msca/en_CA/list/categoryID.70394700?ic…> Both have IPS displays with 1920 x 1200 resolution (nice). Both can probably run linux, but with varying amounts of difficulty. The $74 one has 32-bit UEFI firmware which is annoying for Linux. So I would ignore it. The $119 one has a 64-bit UEFI firmware. At a minimum, you should be able to install Windows Linux subsystem on this (most of text-mode Ubuntu). I have a Win 10 tablet with a similar processor and have been able to boot Ubuntu (some months ago). I needed a kernel parameter that de-tuned the video drive a lot to get it working. With enough experimentation, I could probably have figured out a better work-around. But desktop distros aren't actually much fun on tablets These tablets have very limited USB: one port, USB 2, probably also used to charge tablet. There's something quite interesting about being able to buy a tiny Windows box quite inexpensively and Windows is an OK tablet OS. But generally an Android tablet makes more sense as a tablet (more relevant software, longer battery life). Still, if I didn't already have Windows tablet, I'd consider buying one of these to play with.

Wheezy no longer accepts my passwords to open /home and /mnt partitions on boot
by Ken Heard 08 Dec '16

08 Dec '16

In my Wheezy box I have two encrypted hard drive partitions, /dev/mapper/md07_crypt for /home and /dev/mapper/md05_crypt for /mnt. (Mnt is no longer used. That partition was originally for /tmp; in a weak moment I persuaded myself that I needed to encrypt /tmp. I have since changed the mount point for /tmp to tmpfs and consequently changed the mount point of /dev/mapper/md05_crypt to /mnt pending its deletion. In the meantime it still has to be opened.) This morning, when I tried to boot this box, I found that the passwords for those two partitions were not accepted. Finally, after entering the correct passwords numerous times, the following messages were received. [info] Loading kernel module loop. [info] Loading kernel module coretemp. [info] Loading kernel module it87. [ok] Activating lvm and md swap ... Done [....] Checking file systems ... Fsck from util-linux 2.20.1 BOOT was not cleanly unmounted, check forced. BOOT: 245/120960 files (20.4% non-contiguous) 58505/241664 blocks Fsck.ext4 No such file or directory while trying to open /dev/mapper/md07_crypt. Possibly non-existent device? VAR: recovering journal Fsck died with exit status 9 Failed (code 9). [FAIL] File system check failed. A log is being saved in /var/log/fsck/checkfs if that location is writable. {My note: that location was not writable; so no such log was created.} Please repair the system manually ... Failed! [warn] A maintenance shell will now be started. CONTROL-D will terminate the shell and resume system boot ... (warning) Give root password form maintenance (or type CONTROL-D to continue): After entering the root password the root bang appeared. At this point I did not know what to do by way of reparing the system manually. I consequently closed the box, first by running "shutdown now". After various messages flashed by on the monitor I was asked once more to give the password for maintenance or type CONTROL-D again. After typing CONTROL-D again my user login appeared, but of course I could not log in. At that point I was finally able to close the computer with the Alt-S command. I hope that somebody or bodies can tell me what to do to make this computer usable again -- short of having to do a completely new installation.

implementing "dropbox requests" + encryption
by Matt Price 01 Dec '16

01 Dec '16

Hi everyone, I am trying to finally wean myself off my Dropbox habit. This will probably involve a self-hosted sparkleshare or nextcloud installation, though I haven't really sussed out the alternatives yet. One feature of Dropbox that I use a lot is the "Requests" function, which lets people with a link upload documents to a folder in my dropbox: https://www.dropbox.com/en/help/9090 It has been extremely convenient for me in many ways, but some of the stuff I've been requesting is actually a little sensitive, and should be encrypted. I'd like to set up a similar system to DB Requests, but which encrypts the uploaded files automatically with my public key, or something similar. Has anyone implemented a system of this kind? Any hints on how to do it? Thanks! Matt
