Linux

In an Ubuntu 18.04 two disk setup (/ on SSD, /home on spinning drive), my Ubuntu 18.04 has still defaulted to use swap space on the SSD although there was a swap partition of the same size on the spinning drive. This was not a new install, but a system upgrade from 16.04 (where I had created a swap partition manually on the spinning drive to spare the SSD). Linux is able to determine whether a drive is spinning or not, but apparently the installation/upgrade script was not very smart.

In order to copy all xml files from one directory to another without overwriting existing files with the same name:
cp -vnpr /source/*.xml /destination

I am using the cloud services at CSC and they do not allow ssh login with the traditional login/password combo.
When I want to make a bookmark in my file manager (Nemo) pointing to this location. I need to specify a rsa key file. that is used for the login. On the command line, it looks as follows:

ssh -i ~/.ssh/encypted_rsa_key.pem cloud-user@pouta
