17 Mar 2015 The GNU Manifesto Turns Thirty [41495]
The New Yorker, March 17, 2015

"Unix, one of the earliest computer-operating systems, was developed between the late nineteen-sixties and the early nineteen-eighties, by AT&T Bell Laboratories and various universities around the world, notably the University of California, Berkeley.

It was the product of a highly collaborative process, in which researchers and students built and shared their code in an atmosphere of excitement and discovery that was fostered, in part, by an agreement that AT&T representatives had signed, in 1956, with the Department of Justice, circumscribing the company's commercial activities in exchange for an end to antitrust proceedings.

But in 1982, AT&T was broken up and its agreement with the department ended; before long, the company was selling copies of Unix without including the source code from which it was derived, effectively commercializing the operating system and hiding its building blocks within a proprietary program. The move greatly upset many in the programming community, including Richard Stallman, a software developer in his late twenties who was then working at M.I.T.'s Artificial Intelligence Laboratory..."

10 Mar 2015 Maintaining Configuration Files in Solaris 11.2 [41314]
By Jeff Victor

Jeff Victor writes, "Have you used Solaris 11 and wondered how to maintain customized system configuration files? In the past, and on other Unix/Linux systems, maintaining these configuration files was fraught with peril: extra bolt-on tools are needed to track changes, verify that inappropriate changes were not made, and fix them when something broke them.

A combination of features added to Solaris 10 and 11 address those problems. This blog entry describes the current state of related features, and demonstrates the method that was designed and implemented to automatically deploy and track changes to configuration files, verify consistency, and fix configuration files that 'broke.' Further, these new features are tightly integrated with the Solaris Service Management Facility introduced in Solaris 10 and the packaging system introduced in Solaris 11..."

13 Feb 2015 Master Linux service management on System V and systemd [40875]
SearchDataCenter, February 13th, 2015

"Managing services on Linux is an essential task for administrators. Learn to work with either System V or systemd.

If you're a Windows administrator with a few Linux servers, or a new administrator starting out on Linux, you need to learn how to start, stop and check services. Recent changes have made Linux service management more complicated.

Several items used on Linux were invented in the old days of Unix. One of these is the System V procedure for starting services, which has been the dominant Linux service management method until recently..."
