I was tired of Chrome eating all my laptop resources so I decided to put some limit to it with cgroup.

As I was using Ubuntu 12.04 with support for cgroup, I installed the package cgroup-bin and add the following group to the file /etc/cgconfig.conf:

group browsers {
    cpu {
#       Set the relative share of CPU resources equal to 25%
        cpu.shares = "256";
 }

PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

While there is no way to actually switch a VDI between fixed-size and dynamic, you can clone the existing VDI into a new one with different settings with VBoxManage.

VBoxManage clonehd [old-VDI] [new-VDI] --variant Standard
VBoxManage clonehd [old-VDI] [new-VDI] --variant Fixed

If you want to expand the capacity of a VDI, you can do so with

#!/bin/bash

case "${1:-''}" in
    'start')
        if test -f /tmp/selenium.pid
        then
            echo "Selenium is already running."
        else
            export DISPLAY=localhost:99.0
            java -Dwebdriver.gecko.driver="/usr/lib/geckodriver/geckodriver" -jar /usr/lib/selenium/selenium-server-standalone.jar -port 4444 > /var/log/selenium/output.log 2> /var/log/selenium/error.log & echo $! > /tmp/selenium.pid
