# The Ubuntu USB startup creator often crashes.

# Then check where it is (which device)
df

# Let's say we see it's in /dev/sdb1
# Then we have to use /dev/sdb and NOT /dev/sdb1

# Find out the window ID of the window I want to record
xwininfo -display :0

# Copy the window ID (something similar to 0x4600007)
recordmydesktop --windowid 0x4600007

# Now the inside of the window (AND the mouse pointer if it goes inside) will be recorded
# CTRL + C will stop the recording

# This is a short walk through adding more disk space
# in a VirtualBox machine. There's good detailed information here:
# http://trivialproof.blogspot.com.es/2011/01/resizing-virtualbox-virtual-hard-disk.html

# Change to where your VirtualBox VMs are. For a Linux distribution it could be:
cd ~/VirtualBox\ VMs/

# Find the name of the virtual machine you want to resize
cd YOUR_VIRTUAL_MACHINE
