Boot rpi from hdd 

Boot from my SD card (Debian), with USB Drive connected.

Start up X windows as root (sudo startx)

Run gparted, and create partition on USB drive (use ext4 format, I will assume it is called /dev/sda1)

(you may need to install gparted (apt-get install gparted)

mount the USB drive partition

sudo mkdir /mnt/newroot

sudo mount /dev/sda1 /mnt/newroot

Copy contents of / (root partition to USB /dev/sda1)

(You may need to install rsync, (apt-get install rsync)

sudo rsync -avxS / /mnt/newroot

Change /boot/cmdline.txt

root=/dev/sda1

Reboot RPi.

Confirm you're rootfs is now on /dev/sda1 (The size of the partition will be a big give away here.)

You can now delete the old partition on the SD Card if you want to. I have kept mine as an emergency rootfs if I need it.

SUN rset time in python for camera to  adjust exposure

latitude = 51.21 

longitude = 21.01 

sun = Sun(latitude, longitude) 

# Get today's sunrise and sunset in UTC 

today_sr = sun.get_sunrise_time() 

today_ss = sun.get_sunset_time() 

print('Today at Warsaw the sun raised at {} and get down at {} UTC'. format(today_sr.strftime('%H:%M'), today_ss.strftime('%H:%M'))) 

# On a special date in your machine's local time zone 

abd = datetime.date(2014, 10, 3) 

abd_sr = sun.get_local_sunrise_time(abd)

Access raspi from remote 

$> python -n http.server 

this will start HTTP server that will give dir listing so files can be downloaded from rpi 

we will also need to set port forwarding on router to be able to access from  public IP of the router
