How Free Software Contributed to the Success of Steve Jobs and Apple

We all have to celebrate the career of Steve Jobs and thank him for the tremendous improvements he has brought to computer interfaces and hardware. The guy's amazing, OK? But Apple is something of a control-freak environment with a hard-handed approach to things such as product announcements and the App Store. An undercurrent of disgruntled consumers and policy-minded free software advocates has transferred their historic antipathy for Microsoft to Apple, now that it has become the brilliant business success of the new century. So I'd like to bring everybody together again for an acknowledgment of how important free software has been to Jobs and to Apple.

In the great Second Coming, when Jobs returned to Apple 1996, he drove
two big changes right away: porting over OpenSTEP from NeXT computer
and adopting a version of the open source BSD as Apple's new operating
system. OpenSTEP was a proprietary, platform-independent set of APIs
for Solaris, Windows, and NeXTSTEP. It was derived from NeXTSTEP
itself, the operating system that ran on Jobs's m68k-based NeXT
computers. But NeXT worked with the then-powerful Sun Microsystems,
which had based its own wildly popular SunOS on BSD. OpenSTEP became
the basis for the familiar Cocoa libraries and run-time that Apple
developers now depend on.

(It may seem strange to use the word "Open" in the name of a
proprietary system. But back then--and in some circles even today--the
most rudimentary efforts at interoperability were used to justify the
term. Anybody remember the Open Software Foundation?)

The foundation for the ground-breaking and still strong Mac OS X was a
version of BSD based on
NetBSD and FreeBSD but incorporating some unique
elements
. Adopting BSD brought numerous advantages: it permitted
the Mac to multitask, and it made simple the porting of a huge range
of Unix-based and BSD-based applications that would expand the Mac
from its original role as a desktop for creative artists to a much more
robust and widely deployable system.

Particularly valuable to Apple--and related to its adoption of a Unix
variant--was the port of open source Samba, developed for Linux. Samba
reverse engineers the SMB/CIFS protocol and related protocols that
permit computers to join Microsoft local networks. Apple also (like
NeXT) used the historic GCC compiler developed by Richard Stallman,
and adopted KDE's browser engine (now known as Webkit) for Safari. These free software packages were insanely great; that's why Mac OS X incorporated them.

I think it is the familiarity of the Unix and BSD software that makes the Mac popular among geeks; it is now by far the most popular laptop one sees at computer conferences. And because of all the great server software that runs on the Mac thanks to its BSD core, it's gradually growing in popularity as a server for homes and small businesses.

Apple knew it had a good thing in its BSD-based kernel, because it chose to use it also in the iPhone and follow-on products. As I have reported before, the presence of BSD libraries and tools helped a group of free software advocates reverse engineer the iPhone API and create a public library that permitted people outside Apple for the first time to create applications for the iPhone. This led to a thriving community of iPhone apps, none of them approved by Apple of course, but Apple came out with its own API many months later and legitimized the external developer community with its App Store.

Although the BSD license allowed Apple to keep its changes proprietary, it chose to open-source the resulting operating system under the name Darwin. As a separate project, though, Darwin hasn't seen wide use.

BSD was not Jobs's first alliance with free software. The NeXT computer was based on the open source Mach 3 kernel developed by Richard Rashid at Carnegie Mellon University. Mach emulated FreeBSD (even though Rashid personally expressed a distaste for it) for its programmer and user interface. Some elements of Mach 3 were incorporated into Darwin, and (to digress a bit) Mach 3 has gone on to have major effects on the computer industry. It was an inspiration for the microkernel design of Microsoft's NT system, which thrust Microsoft into the modern age of operating systems and servers especially. And Rashid himself took a position as Senior Vice President of Research at Microsoft a few years ago.

The impacts of broad, leaderless, idea-based movements are often surprising and hard to trace, and that's true of open source and free software. The triumphs of Steve Jobs demonstrate this principle--even though free software is the antithesis of how Apple runs its own business. Innovators such as Andrew Tridgell, with Samba and rsync, just keep amazing us over and over again, showing that free software doesn't recognize limits to its accomplishments. A lot of computing history would be very different, and poorer, without it.

Opening Education Beyond the Property Relation: From Commons to Communism.

Paper accepted for the Open Education Conference 2010

Abstract

Open Education, and specifically the OER movement, seeks to provide universal access to knowledge, undermining the historical enclosure and the increasing privatisation of the public education system. In this paper we examine this aspiration by submitting the implicit theoretical assumptions of Open Education to the test of critical political economy. We acknowledge the Open Education movement's revolutionary potential but outline the inherent limitations of its current focus on the commons (property relations) rather than the social relations of capitalist production (wage work, the company) and because of this, argue that it will only achieve limited, rather than revolutionary, impact.

Introduction

The opening of education beyond the property relation is distinguished by two terms that are often used interchangeably, yet retain subtle differences: Open Education and Open Educational Resources.

Open Education refers to recent efforts by individuals and organisations across the world to use the Internet to share knowledge, ideas, teaching practices, infrastructure, tools and resources, inside and outside formal educational settings. Through collaboration and experimentation, new pedagogies and curricula are emerging. Although the term Open Education has been used since the 1960s, the current dominant use of the term refers to co-ordinated efforts during the past decade to exploit the growing availability of personal computers and increasingly ubiquitous high speed networks.

Open Educational Resources (OER) refers to both the worldwide community effort to create an educational commons and the actual “educational materials and resources offered freely and openly for anyone to use and under some licenses to re-mix, improve and redistribute” (Wikipedia). Typically, those resources are made available under a Creative Commons license and include both learning resources and tools by which those resources are created, managed and disseminated. As both a means of protecting and liberating research, teaching and learning materials, OER relies heavily on the use of open licenses, all of which are in one way or another derived from the General Public License (GPL) and Berkeley Software Distribution (BSD) licenses first created in 1989. Since the 1990s, software has been created and distributed using such licenses and it is widely acknowledged that Creative Commons was inspired by, and drew experience from, the use of open licenses in the world of software.
