# i want to stream netflix and prime video from my chromecast to the hotel TV
#
# hotels often have an authentication / agreement page that you have to click OK on
# chromecasts do not play nicely with those
#
# solution: connect your laptop to the hotel's wi-fi, then set up an AP and connect the chromecast to the AP
#           your laptop will be both a client of the hotel's WLAN and an access point + bridge of your own WLAN

# prerequisites
#    1) you have a (Linux) EC2 instance with SSH enabled, source/destination check disabled, etc.
#    2) you have a security group rule with a tag named roaming (this script updates that rule to allow you access) (note: tag the rule, not the security group)

# grant access to your IP access
myip=$(curl -s https://ipv4.icanhazip.com)
read sgid sgrid < <(echo $(aws ec2 describe-security-group-rules --filter Name=tag:Name,Values=roaming | jq '.SecurityGroupRules[0].GroupId, .SecurityGroupRules[0].SecurityGroupRuleId' -r))
aws ec2 modify-security-group-rules --group-id $sgid --security-group-rules SecurityGroupRuleId=$sgrid,SecurityGroupRule=\{CidrIpv4=$myip\/32,FromPort=22,ToPort=22,IpProtocol=TCP,Description=roaming\}

# i often click between the buttons on my touchpad.
# this is because the touchpad is lined up with the center of the laptop
# rather than the center of the keyboard home row
# this script finds the device id of the touchpad (which changes as devices are plugged/unplugged) and disables the triple click

# note: on new installations, run xinput to identify your touchpad which may not contain the word TouchPad

touchPadId=$(xinput | grep TouchPad | awk -F 'id=' '{print $2}' | cut -f1)
xinput --set-button-map $touchPadId 1 1 3

# jq-say
# format string as JSON message
#
# treat odd args as keys and even args as values
# use jq to output something like this, for as many args supplied:
#   {"arg1": "arg2", "arg3": "arg4"}
#
# very helpful for echo'ing log messages as JSON
