Swappiness

Swappiness

# The default swappiness in Ubuntu 60. Reducing the default value of swappiness will probably improve overall performance for a typical Ubuntu desktop installation. A value of swappiness=10 is recommended, but feel free to experiment.
# Checkout swappiness value
cat /proc/sys/vm/swappiness

# Switch swap off
sudo swapoff -a

cURL, git, ssl in Jailbreak iPhone

Change default shell

Editing /etc/passwd won't work in iOS, so in order to change default shell in iOS you need to edit /etc/master.passwd. You can change root's default shell to bash like this -- root:/smx7MYTQIi2M:0:0::0:0:System Administrator:/var/root:/bin/bash.
