1. '[{ "DeviceName":"/dev/sdb", "VirtualName":"ephemeral0" }]'

For 50G EBS attached on boot (auto-deleted on terminate unless you override), block device mapping becomes:

1.  '[{ "DeviceName":"/dev/sdb", "VirtualName":"ephemeral0" },{"DeviceName":"/dev/sdc","Ebs":{"VolumeSize":50}}]'

WARNING: "Ebs" is very case sensitive here.

To encrypt the Ebs volume, add "Encrypted": true to the device params like so:

1.  {"DeviceName":"/dev/sdc","Ebs":{"VolumeSize":50,"Encrypted": true}}

Selenium test on CLI in 5 minutes using Java

This took me two weeks to nail down looking at it here and there.

1. mkdir stests
2. cd stests
3. wget http://selenium.googlecode.com/files/selenium-java-2.33.0.zip
4. unzip selenium-java-2.33.0.zip
5. mkdir jars
6. find selenium-2.33.0 -type f -name '*jar' -exec mv -v {} jars \;
7. rm -rfv selenium-*
8. mkdir src
9. vi src/Test.java
1. use below code
10. mkdir out
11. javac -d out -cp 'jars/*' src/MyTest.java
1. ignore "Notes" output
12. cd out
13. rm -rfv org
14. java -cp '../jars/*:.' MyTest
