xfce4 background, and linux command line xml parse example

xml script example

#!/bin/bash -
# taken from
# must install xmllint
# /usr/bin/xmllint      libxml2-utils
# define xfce4 xml file that holds info about desktops 
DESKTOP="/home/$(id -un)/.config/xfce4/xfconf/xfce-perchannel-xml/xfce4-desktop.xml"
# define xpath that will extract current desktop background file name
# (NB I am no expert in xpaths and there is probably a much more elegant way
#  to do this but this works for me)
# use xmllint utility to apply xpath to file and extract file path and name
IMAGE=$(xmllint --xpath "string(${XPATH})" "${DESKTOP}")
# display the file info extracted
echo Current Wallpaper File = ${IMAGE}
# rest of script........

windows 10 miracast remote display on other device

Windows 10 tablet keyboard, adding arrow keys.

To enable this layout:
  1. From the Start screen, open Settings (hidden behind the “hamburger” icon in the tablet mode). Another way to start the Settings app is the “All Settings” action icon in the notification center.
  2. In the Settings app, select DevicesTyping.
  3. Turn on the “Add the standard keyboard layout as a touch keyboard option” switch.
After enabling the layout you can switch to it using the rightmost icon in the keyboard options menu:

the standard keyboard has up and down arrow keys, useful for scrollback.  should be in the menu, but guess they don't use the keyboard and omitted them.
