Access EC2 Linux box over ssh without .pem file SHELL SSH AWS AMAZON LINUX EC2 BASH You may be in the situation where you need to access your EC2 instance from any machine, not necessarily your own. It's a pain to carry around your .pem file and a bad idea to leave it on someone elses machine too. Here's a solution to let you login to your insta…
1. Login to your EC2 instance using your .pem file
ssh -i your_pem_file.pem ubuntu@ec2-________.compute-1.amazonaws.com
2. Create a new user that will access the instance using a password:
$ sudo useradd -s /bin/bash -m -d /home/USERNAME -g root USERNAME
where:
-s /bin/bash : use /bin/bash as the standard shell
-m -d /home/USERNAME : create a home directory at /home/USERNAME

Type Inference in Swift’s Closure
// Credit: Stanford’s Developing iOS8 App with Swift Course (Available via iTunes U Course via Apple Swift Portal)
// This function itself accept a closure, and return nothing
func performOperation(operation: (Double, Double) -> Double) {
println(operation(20.0,10.0))
}
// Thanks to type inference, we can further simplify the following
// function call that accept a well defined closure as argument
performOperation({ (op1: Double, op2: Double) -> Double in
return op1 * op2
