Generating v5 UUID. What is name and namespace?
... and namespace can be used to create a hierarchy of (very probably) unique UUIDs.
Roughly speaking, a type 3 or type 5 UUID is generated by hashing together a namespace identifier with a name. Type 3 UUIDs use MD5 and type 5 UUIDs use SHA1. Only 128-bits are available and 5 bits are used to specify...
Efficient method to generate UUID String in JAVA (UUID.randomUUID().toString() without the dashes)
I would like an efficient utility to generate unique sequences of bytes. UUID is a good candidate but UUID.randomUUID().toString() generates stuff like 44e128a5-ac7a-4c9a-be4c-224b6bf81b20 which is good, but I would prefer dash-less string.

If you are on linux, you can alternatively call /usr/bin/uuidgen.
package main
import (
"fmt"
"log"
"os/exec"

Generating a UUID in Postgres for Insert statement?
My question is rather simple. I'm aware of the concept of a UUID and I want to generate one to refer to each 'item' from a 'store' in my DB with. Seems reasonable right?

How unique is UUID?
How safe is it to use UUID to uniquely identify something (I'm using it for files uploaded to the server)? As I understand it, it is based off random numbers. However, it seems to me that given enough time, it would eventually repeat it self, just by pure chance. Is there a better system or a patter...
