Good puppies start long before breeding ever takes place. Both parents need long-term care -- what dog people call conditioning -- to produce the best offspring. This means regular veterinary care, screening for genetic problems, pre-breeding tests, and regular exercise and good nutrition.
A universally unique identifier (UUID) is an identifier standard used in software construction. A UUID is simply a 128-bit value. The meaning of each bit is defined by any of several variants. For human-readable display, many systems use a canonical format using hexadecimal text with inserted hyphen characters.
To determine the version 3 UUID of a given name, the UUID of the namespace (e.g., 6ba7b810-9dad-11d1-80b4-00c04fd430c8 for a domain) is transformed to a string of bytes corresponding to its hexadecimal digits, concatenated with the input name, hashed with MD5 yielding 128 bits.
