How to mount Amazon EC2 EBS volume on an instance’s file system

The following assumes you have created a volume in AWS Management Console and attached it to your instance as /dev/sdh.
 
A brand new volume is unformatted block storage.  It shows up as another device, but doesn’t contain a filesystem.  (An EBS volume that previously had a filesystem created on it won’t be mounted either by the attachment process).
 
You can verify that your instance can see the EBS volume by running the following command on the instance:
 
cat /proc/partitions
 
You’ll see an entry for sdh.  At this point, you should create a filesystem and mount it manually.  You could create an EXT3 filesystem on the device and then mount it on ‘/mnt/ebs’ with the following commands, (run as root):
 
mke2fs -F -j /dev/sdh
mkdir /mnt/ebs

mount /dev/sdh /mnt/ebs 

Android 1.6 Version Update (Donut) adds new Power Control Widget

I’m a developer and have made a few apps for android, so I updated to the newest SDK today, Android 1.6, named "Donut". It’s supposed to roll out in October.

One of the first new things I noticed was a nifty power control widget, which gives you the ability to quickly toggle wifi, bluetooth, gps, data syncing, and brightness. Not a particularly big deal, because I’m currently using worthy widgets downloaded from the market, but it’s nice to have it natively for sure. Still waiting on a 3g toggle though…
