Standardization is required to scale anything.
IETF(Internet Engineering Task Force) formalized many important standard, in the format of RFC. E.g.
- RFC 20: ASCII
- RFC 793: TCP
- RFC 2460: IPv6
- RFC 6749: OAuth
- RFC 7540/7541: TTP/2
RFC 2119 defines the keywords to indicate requirement levels: MUST/MUST NOT/SHOULD/SHOULD NOT
Portable Operating System Interface (POSIX): a family of standards specified by the IEEE Computer Society for maintaining compatibility between operating systems.
- command line shells and utility interfaces
POSIX standards form the core of the Single UNIX Specification.
OS X is compliant.
The LSB is based on the POSIX specification, the Single UNIX Specification (SUS), and several other open standards, but extends them in certain areas.
The LSB specifies for example: standard libraries, a number of commands and utilities that extend the POSIX standard, the layout of the file system hierarchy, run levels, the printing system, including spoolers such as CUPS and tools like Foomatic and several extensions to the X Window System.
- ABI: application binary interface (The LSB is designed to be binary-compatible)
To get LSB version:
$ lsb_release -a
There are conflicts between the LSB and The POSIX standards
MAJOR: backward incompatible
MINOR: new functionality, backward compatible
PATCH: bug fix only
