Bootable USB

In case your laptop has good old booting system and not advanced system like UEFI, you can use following command to create bootable USB. In case your laptop is fancy, you will have to use software like Rufus which works only on amazing windows.

sudo dd bs=4M if=~/Downloads/ of=/dev/sdc1 status=progress oflag=sync

you can find out /dev/sdc1 via df command.

Highlight mouse with win + F5

When you have multiple monitors, and we need to search for a mouse, it becomes difficult to see where its hiding. Windows had a good feature to highlight mouse when you press Ctrl, but linux typically dont have that. So I used following workaround to achieve same effect in i3.

sudo apt install libx11-dev libxcomposite-dev libxdamage-dev libxrender-dev
mkdir ~/git
cd git
git clone https://github.com/Carpetsmoker/find-cursor.git
cd find-cursor
make
echo "bindsym $mod+F5 exec /home/maahi/git/find-cursor/find-cursor -of" >> ~/.config/i3/config

docker commands

A while ago, I was playing around with docker. Here is the collection of all the commands I used. I used following to install dockers:

sudo echo 'deb https://apt.dockerproject.org/repo debian-stretch main' > /etc/apt/sources.list.d/dockertemp.list
sudo apt-get update
sudo apt-get install docker-engine
sudo rm /etc/apt/sources.list.d/dockertemp.list sudo service docker start

 Once installation was done, these were basic commands I used :

sudo docker push harsshal/tws:second
