JavaScript function that converts Hrs & Minutes into Decimal Hrs. It uses a Hash structure in Javascript to store the equivalencies. Intended audience: Use by Employees who need to enter Decimal time values for their time cards at work. Further down the line, this logic will be refactored into a Service that can be used programmatically by time-…

Classic program that prints strings based on results of using MOD function against a List
/*
Write a program that prints out the numbers 1 to 100 (inclusive).
If the number is divisible by 3, print Crackle instead of the number.
If it's divisible by 5, print Pop. If it's divisible by both 3 and 5,
print CracklePop. You can use any language.

/// any number x where x % y is divisible by that number. We'll use that fact to match boolean patterns in Scala.
//// In Scala RePL, copy-paste the function first. Then use the function in a second call from the REPL.

infomaven / ec2_getIP
Last active November 8, 2015 17:17
While you can get the public and private IP address of your Amazon EC2 instance via the AWS Console, it may be extremely useful to query it from anywhere you can make an HTTP request, such a shell script. The operation is really simple, just make a GET request to the following URL from within your EC2 instance:
Local IP:
curl http://169.254.169.254/latest/meta-data/local-ipv4
Public IP:
curl http://169.254.169.254/latest/meta-data/public-ipv4
I often use this feature to pre-configure services and update configuration files, as in EC2 you get a new IP Address each time you reboot

Enum optimization
// create an alternative method for getting a list of defined enums to avoid system creating a clone of the String array
// this is the .values() method
public enum Car {
TESLA, VOLVO, TOYOTA;
