We have used the most recent beagleboard debian eMMC flasher image to flash the beagle bone black eMMC. As of this writing: wget http://debian.beagleboard.org/images/BBB-eMMC-flasher-debian-7.5-2014-05-14-2gb.img.xz After flashing is complete, erase the sd card, then reboot. Once booted, We can use fdisk -l to list our available devices, I found mine by checking the size and the partition table. After verfifying the card's address, we can reformat it to fit our needs. Of course, this can be done before plugging the card in, as well.

debian@beaglebone:~$ fdisk -l
Disk /dev/mmcblk0: 15.9 GB, 15931539456 bytes 
        Device Boot      Start         End      Blocks   Id  System

Redirect: Temporary and Permanent

Source

What is an HTTP Redirect?

HTTP redirection, or URL redirection, is a technique of pointing one domain or address to another. There are many uses for redirection, and a few different kinds of redirection to consider.

As you create content and administrate servers, you will often find the need to redirect traffic from one place to another. This guide will discuss the different use-cases for these techniques, and how to accomplish them in Apache and Nginx.
