Turn off the spotlight and turn it on

Turn off the spotlight and turn it on using these commands in terminal.
sudo mdutil -i off

sudo mdutil -E /

Monitor Temperature in Mac using bash script command line

The code is simple thanks to the temperature monitor app
Just do ./runTapp.sh &
in the terminal, and you are good to go!
#!/bin/sh
cd /Applications/TemperatureMonitor.app/Contents/MacOS/
./tempmonitor -th > ~/Desktop/CPUtempData.csv
while true
do
    ./tempmonitor -tv >> ~/Desktop/CPUtempData.csv
    /bin/sleep 60
done

Map Subsection USA States using matlab

I had the regional PM2.5 map, but I wanted to have it by states. So, came up with this code which can generate state level maps. If you use it, please let me know. Current example uses the solar radiation from GCM.


Highlight one, highlight all!

There is also R version available, at:
