I reduce the time for this to process to save time at boot.
I edited networking.services

sudo nano /etc/systemd/system/network-online.target.wants/networking.service

Change

TimeoutStartSec=5min

To

TimeoutStartSec=2s

Then reboot.

Alright Dota 2 perfectly working on my Ubuntu 18.04LTS ( AMD PC ). 

If you have created your own circuit which run from a microcontroller. You want to control your appliances, motor or any AC load. You probably notice some issue regarding a relay when you control the AC load.

When there is no load in the relay, the circuit runs fine. Now what if we put some load in the relay like a motor. You might notice that the circuit has some issue like it will reset itself or some abnormalities from the circuit.

This where the RC snubber is very important, you just put a RC snubber to the output of the relay. Just what I did in my circuit.

For iOS10 it only show the "Apps" folder.
If you don't even have that, please do:

idevicepair unpair
idevicepair pair

Do the last one multiple times until successful (follow the hints on screen)
Finally reboot your computer.

Now, you will not have access to your media still. It must be a simple bug because it can be solved with:

mkdir ~/Desktop/iOSmount
ifuse ~/Desktop/iOSmount

Note that you will need root permissions to unmount this:

Backup Raspberry Pi SD Card

1. Insert the SD card in your PC using a USB or built-in card reader. Now open a Terminalwindow, and enter the command sudo fdisk -l. This will list all the filesystems present on your system.

2. Try to find out the device name of your SD card. I have a 16GB SD card, so it is easily identified as the device /dev/sdb which has a size of 14.9GB. This is because the actual storage on a device is always slightly lower than advertised. Note down this device name.

$ sudo systemctl restart NetworkManager

$ drush sql-dump --gzip --result-file=~/path-here/sql-dump.sql

I created my own shell script dump_db.sh to make less hustle.
Inside my dump_db.sh

#!/bin/bash

if [ -z "$1" ];
then
  echo "Please specify if its dev or prod" 
  exit 1
else
  dev="$1"
fi

if [ -z "$2" ];
then 
  echo "Please specify the database name"
  exit 1
else
  db="$2"
fi

echo "Exporting database"
drush sql-dump --gzip --result-file=~/backup/$(date +%Y%m%d-%H.%M)-"$dev"-"$db".sql

I would run this:

$ source dump_db.sh dev drupalista.net

$ gzip -d < db.sql.gz | drush sqlc
