Q I'm trying to create a print server for an MFC-7860DW. Printing works properly, but after installing “cloudprint” using PIP, I get an error message.
A Sharing a printer is a lot easier than you thought. See: https://help.ubuntu.com/community/NetworkPrintingWithUbuntu
Q I am using Linux Mint Qiana with Kernel 3.13, and LMDE with Kernel 3.11.2, so why is V3.10 newsworthy?
A (Thanks to Ronnie) Kernel 3.10.41 is an LTS release, so it will receive support for several years. See https://www.kernel.org/category/releases.html
Q How do you do a simple sum in LibreOffice calc?
A Put the cursor where you want the sum, click the sum icon, press enter.
Q I have done many updates, and a couple of version upgrades, but Grub still shows me only the original kernel versions.
A (Thanks to RobertKH in the Ubuntu Forums) Run these commands:
sudo grub-install /dev/sda
sudo update-grub
Q I installed NS2, but I can’t find where the files were installed in order to modify some of them. Specifically I want to modify aodv.h and aodv.cc for a project of mine.
A If you install Synaptic Package Manager and search for ns2, you can right-click and select “properties”. One of the tabs is “installed files,” which shows you all the files, and their locations. It works only for installed packages.
Q How can I make an application open where I want it in Kubuntu?
A (Thanks to AnotherKevin in the Ubuntu Forums.) Position the window to the place on your desktop you want it to go when you start the application. Next, click the icon in the upper left corner of the app's border. Choose More Actions » Special Window Settings. In the box that follows, tick the boxes for Position and Size, then, using the drop-down lists, choose Remember.
Q How can I delay a startup application in 14.04?
A (Thanks to mc4man in the Ubuntu Forums) In your home folder, go to the hidden folder .config/autostart, and locate the .desktop file for your application. Edit the file, adding a line to the end:
X-GNOME-Autostart-Delay=30
where 30 is the number of seconds of delay you want.
It won't work for Dropbox, because Dropbox rewrites its .desktop file every time it runs.
Q I have a new laptop with Windows 8.1 installed. I plan to dual-boot with Ubuntu 14.04. Should I turn off UEFI and secure boot? When should I set up the partitions?
A No, leave UEFI and secure boot enabled. Use Windows to shrink the existing partition(s) so there is space for Ubuntu. Always select “something else” during installation, and explicitly set up the partitions as you want them.

I'm depressed. In order to produce this column, I spend a significant amount of time browsing the Ubuntu Forums, as well as other resources. I see a lot of questions which are incomplete, contradictory, unclear and ungrammatical – even from people who are obviously English speakers. And that's OK.
However, at least a third of the “answers” demonstrate that the author has not read the question. One person had a question about Wi-Fi, and a forum moderator (!) asked him to provide additional information – except that none of it was relevant to a wireless adapter. People who have written thousands of posts make stupid suggestions. I would love to ridicule them, but that would get me banned from the forums.
It's great to see so many people trying to be helpful. It would be even better if they would carefully read the question, so they don't write nonsense.
