How to set transparency with hex value ?

For example, you want to set 40% alpha transparence to #000000 (black color), you need to add 66 like this #66000000.

Convert UUID to byte array and vice versa. Useful for when UUIDs are stored in MySQL tables as VARBINARY(16)
import java.nio.ByteBuffer;
import java.util.UUID;
public class UuidAdapter {
public static byte[] getBytesFromUUID(UUID uuid) {
ByteBuffer bb = ByteBuffer.wrap(new byte[16]);
bb.putLong(uuid.getMostSignificantBits());
bb.putLong(uuid.getLeastSignificantBits());
return bb.array();

This assumes that:

  • You are using Nginx.
  • You want to accept incoming connections on port 80.
  • Your Node.js app is listening on port 3000.
  • You want to be able to connect to your Node.js instance directly as well as via the load balancer.

####1. Create load balancer
