comment Is it safe to modify thunderbird mail box from python?
It should be possible to copy your whole profile folder to another location and start Thunderbird using thunderbird -P profile . This way you can try anything you want to on the copy without touching the "live" data. NOTE: This assumes you're using POP. Don't try this using an IMAP account because any change you manage to make to an IMAP account will either be undone as soon as you connect to the server or any errors that survive that will probably affect the server. Not good!

comment Ubuntu grub not showing. Oprating System not found
I'm not sure these will help in your case, but there are three things I would try: supergrubdisk supergrubdisk.org . Once grub is back (and assuming it found your OS partitions), you can tweak things very nicely using grub customizer which has a very nice gui interface. You boot from an Ubuntu live cd and install it (in the live cd OS) from somewhere like grub-customizer.en.uptodown.com/ubuntu and then run it. It will find the "real" disk and let you modify the boot menu. Also see gparted live cd download.cnet.com/GParted-Live/3000-2094_4-10698802.html

comment Ubuntu rendering fonts in a weird manner
I had a nastier problem with fonts a few years ago where the login screen had huge unreadable fonts. Until it got fixed by updates much later, I got around it by adding the nomodeset flag to my kernel boot command. If the suggestion from @Rmano doesn't work, then you might try that. ubuntuforums.org/showthread.php?t=1613132 I'm not sure if this would help you or not, but setting it once using the grub edit boot command line option will tell you if it helps.

comment Why doesn't Ubuntu remove old kernels automatically?
As @Rinzwind points out, there are really two issues here. How and when/if to do it. I used to use ubuntu-tweak and it worked, but didn't like KDE (which I use) very much. Now, whenever I get a kernel update, I go into the muon gui package manager, search for kernel, find the one to delete, add it's last number like 36 to kernel - kernel 36, sort on installed, and select the 2 or 3 packages to be removed. It's easy. It's also manual, so if I have compiled any driver modules that still need an older kernel, that kernel won't get deleted until I'm ready for that to happen.

comment Ubuntu 14.04 Login Loop Issue
This is way beyond what I understand, but I'll tell you what I do see: Pam is some sort of security system for your computer. It is trying to do something with kwalletmanager, the program which is a password safe for KDE. But, it is trying to access what appears to be a library it uses to do so - /lib/security/pam_kwallet.so and can't find it. Check if that file exists and what its permissions are if it does (along with the directory it lives in). You might install apt-file and use it to find what package that file comes from to see if it is installed and updated correctly. apt-file update 1st

comment Affect to Applications caused by Security Updates?
I don't know much when it comes to servers, but if I had one running anything even slightly critical, I would want to verify I had a working backup, take it out of service, then run the update and make sure it works and only then would I let it loose on the world. As a desktop user, most updates are harmless, but every so often, one breaks something and I have to spend time figuring out what happened and how to fix it. I wouldn't want to be in that position with data getting corrupted or users breathing down my neck about a service which is broken.

comment Preparing Ubuntu to be turned off unexpectedly?
This is for if they unplug it. If they're actually turning off a power switch, you can replace the power switch with one that just tells the computer to shutdown. I don't know how to do that, but it should be fairly easy.

comment Preparing Ubuntu to be turned off unexpectedly?
@Fabby - That gives me an idea. If you add a smart battery backup instead of a plain UPS, it can sense when power has been removed and send message to your system which can be used to initiate a normal shutdown. The battery will provide the power while the shutdown is being performed. I had an old APC which talked over a serial port. I'm sure all the new ones use USB.

comment Is it possible to put a GUI to more than just TTY7?
Although it's not exactly what you asked for, KDE has a feature called Activities. When you switch activities, you get a whole new set of desktops, possibly setup quite differently from your default. This sort of does the same thing as what you're asking for, but, AFAIK, does stay within one X session.

comment How can I see the amount of data I am Downloading / Uploading per day?
That's a really cool command I have not seen before! You could also get a much less accurate answer using ifconfig etho, but that will show everything sent and received - including control information, not just uploads and downloads. Also, if your router has a web interface like most do, it may display similar information on one of its status pages. Again, this is for everything, not just a particular type of data/traffic.

comment ln -s vs mount --bind
I haven't used mount --bind, but I doubt it can replicate the behavior of a symlink like ln -s ../../myfile .. If you move that to another directory, it will point somewhere else because it's a relative link. This can be useful if you need to backup a sub-tree and still have the links work in the backup.

comment Replace windows with ubuntu: What should I check in Ubuntu live
Along the same lines, if you have a backlit keyboard on a notebook, be sure to check that too. I finally go mine to work after almost 3 years. All I had to do was boot Windows (dual boot) and then turn the power off! This is way less than elegant, but is indicative of what can happen with special hardware.

comment Kde : How to minimize windows from the task bar
Don't know, but: What happens if you right click on an icon? Do you get a context menu with a Minimize option and does it work? (I'm using Kubuntu 14.04 and it already works the way you expect it to.) Do you have the taskbar set to show all windows or just the ones on the current desktop? I ask these primarily to get more info so someone may get a clue as to what's wrong with your setup. Also, what did you upgrade from - or was it a clean install?

comment Add column from one .csv to another .csv file
Thanks for the reply. I'm not sure what I want. I have to play with the actual data, but it would be things like subtotals per week of credits and debits. I also had some call center utilization data where I wanted to sum and average calls per minute. Nothing Fancy. I barely got a C in statistics for social sciences and I've forgotten most of that. I also would like to select columns without pre-filtering it in awk, etc.. I can code all of it in a programming language like awk, but for such a common task, there should be something that already knows how to do it.

+1 for showing me another tool for CSV data. Separate question, but do you know of a standalone report writer for CSV data files?

comment How to block specific apps from opening in specific accounts
I don't know enough to actually do it, but maybe you could setup all the critical applications to be accessible only by a group. Then, you could add advanced users to that group for full access. For the restricted users, you could use sudo (not to root) along with appropriate entries in sudoers to give them password protected access to the other commands on a case by case basis.

comment Printing footers using enscript
Thanks for the great information. It wasn't clear to me that your solution works without the patch. I use .enscriptrc. I didn't notice that .enscript is also available for the use you suggest. The enscript man page lists all those variables, but I didn't make the connection that you had to use them in custom header files.
