Open Source Software / Free Software (OSS/FS or FLOSS) References
This short paper gives links to important pages related to
Open Source Software / Free Software (OSS/FS), also called
Free-Libre / Open Source Software (FLOSS) or FOSS.
This idea / movement / community has risen to prominence, and I've
found it very interesting.
The following are the links I've found most helpful to understanding it.
You can find definitions for the terms
open source software
(OSS, defined in the Open Source Definition) and
(defined by the Free Software Foundation (FSF)).
In practice, nearly all software meeting one definition also meets the other.
In summary, OSS/FS programs are programs whose licenses permit
users the freedom to run the program for any purpose,
to study and modify the program, and to freely redistribute copies of the
original or modified program.
The motives (or at least the emphasis)
of the people who use the term ``open source'' are sometimes different than
those who use the term ``Free Software.''
The term ``open source software'' (a term championed by Eric Raymond)
is often used by people who wish to stress aspects such as high reliability
and flexibility of the resulting program as the primary motivation
for developing such software.
In contrast, the term ``Free Software'' (used in this way)
stresses freedom from control by another (the standard explanation is
``think free speech, not free beer'').
The FSF has a page written by its founder, Richard Stallman,
prefers the term ``free software'' instead of ``open source software''.
has some commentary about these two terms as well.
Merrill Lynch executive Robert Lefkowitz found what may be a better
way to describe the phrase free software:
"We like to think of it as 'free as in market.'"
A speech by Tony
Stanco describes some of the issues of free software; a good quote
from it is that "[in cyberspace] software is the
functional equivalent to law in real space, because it controls people,
just like law does... [it is] much more obedient and
therefore dangerous in the wrong hands."
In contrast, Eric Raymond's
Open Source Initiative declares that the term ``open source''
is ``a marketing program
for free software'' (and recommends using
the term ``open source'' instead).
In a similar manner,
the most widely used OSS/FS operating system is
referred to by two names: ``GNU/Linux'' and simply ``Linux.''
``GNU'' is pronounced ``guh-new'', and ``Linux'' rhymes with ``cynics.''
Technically, the name ``Linux'' is just the name of one system component
(the ``kernel''), but often ``Linux'' is used to mean the entire system.
Richard Stallman has written an article on
why he believes
GNU/Linux should be the preferred term when discussing the entire
system, as well as a
The advantage of the term ``GNU/Linux'' is that it properly gives credit
to the organization most responsible for its development - the
FSF's GNU project.
Not only did the FSF spearhead the initial work, but
as measured by
lines of code the GNU project contributes far more code than
the Linux kernel does.
An advantage of the term ``Linux'' is that it's much easier to say.
It's also worth noting that many other organizations besides GNU
helped develop GNU/Linux, and calling the result ``GNU/Linux'' doesn't
give them credit.
I try to use the term ``GNU/Linux'' here and in my related paper
Why Open Source Software /
Free Software? Look at the Numbers!, simply to be consistent
(I have to pick a name!).
In person, and in some other articles, I use either one;
while names are important, I'm more interested in clear communication.
The Free Software Foundation has developed a set of
categories of software that you may find helpful.
The word "free" has many different meanings, and these different meanings
often make it harder to understand OSS/FS.
The term "Free software" (as used in OSS/FS literature) is based on the word
"freedom" (the word "libre" is used in some other languages).
However, "free" can also mean "no cost", and sometimes "no cost" products come
with a "catch" that in fact is the opposite of freedom.
A LinuxToday posting
found a simple way to express these different meanings of the word
free, which I'll slightly paraphrase here:
Free can mean:
Indeed, the notion of being "free from control by another"
is a concept that many OSS/FS advocates or sympathizers emphasize.
For example, ZDNet's article by David Berlind titled
Who gave Microsoft control of your IT costs? You did, states that
"Let this be a lesson: The minute you get you or your company hooked
on a proprietary technology, you put the vendor of that technology
in control of a lot of things that I'm certain you'd prefer to control..."
This is publicly known to be Microsoft's approach;
as reported by Cnet (July 2, 1998), Bill Gates said that
"about 3 million computers get sold every year in China,
but people don't pay for the software... Someday they will, though.
As long as they are going to steal it, we want them to steal ours.
They'll get sort of addicted, and then we'll somehow figure out how
to collect sometime in the next decade."
Colin Stefani noted on August 1, 2002, that the license for
Windows update "SP3" now requires that users give automatic consent
to send to Microsoft not only their product identification number, but
the names and version numbers of every software package, and
the id's of every hardware device.
Many people fear this kind of loss of privacy.
At one time, it was widely understood that while commercial off the shelf
(COTS) products were useful, you needed to stick with standards so
that you had the freedom to switch to competing products when necessary.
That lesson has had to be re-learned by some people quite painfully.
- They are not all the same.
- Free, as in free speech.
- Free, as in free beer.
- Free, as in free cocaine ("the first one is on me").
Don't confuse ``open source software'' or ``free software''
with ``non-commercial'' software -- there are many examples
of commercial open source / free software, and OSS/FS must be
usable for commercial purposes.
Antonyms of OSS/FS are ``closed'' and ``proprietary'' software.
Essentially all of today's software is licensed; to be OSS/FS, the software
license has to follow certain rules.
As noted above, although there are two different definitions
(for open source software and
in practice a license either meets or doesn't meet both definitions.
Software Release Practice HOWTO
discusses briefly why license choices are so important to
The license you choose defines the social contract you wish to set up among your co-developers and users ...
Who counts as an author can be very complicated, especially for software that has been worked on by many hands. This is why licenses are important. By setting out the terms under
which material can be used, they grant rights to the users that protect them from arbitrary actions by the copyright holders.
In proprietary software, the license terms are designed to protect the copyright. They're a way of granting a few rights to users while reserving as much legal territory is possible for
the owner (the copyright holder). The copyright holder is very important, and the license logic so restrictive that the exact technicalities of the license terms are usually unimportant.
In open-source software, the situation is usually the exact opposite; the copyright exists to protect the license. The only rights the copyright holder always keeps are to enforce the
license. Otherwise, only a few rights are reserved and most choices pass to the user. In particular, the copyright holder cannot change the terms on a copy you already have.
Therefore, in open-source software the copyright holder is almost irrelevant -- but the license terms are very important.
There are dozens of OSS/FS licenses, but nearly all OSS/FS
software uses one of the four major licenses:
the GNU General Public License (GPL),
the GNU Lesser (or Library) General Public License (LGPL),
the MIT (aka X11) license, and the BSD-new license.
Indeed the Open Source Initiative refers to these four licenses as the
classic open source licenses.
The GPL and LGPL are termed ``copylefting'' licenses, that is,
these licenses are designed to prevent the code from becoming proprietary.
See Perens' paper for more information comparing these licenses.
The GPL allows anyone to use the program and modify it, but
prevents code from becoming proprietary once distributed and it also
forbids proprietary programs from "linking" to it.
The MIT and BSD-new licenses let anyone do almost anything with the code
except sue the authors.
One minor complication:
there are actually two "BSD" licenses, sometimes called "BSD-old" and
"BSD-new"; new programs should use BSD-new instead of BSD-old.
The LGPL is a compromise between the GPL and MIT/BSD-new approaches and
is primarily intended for code libraries;
like the GPL, LGPL-licensed software
cannot be changed and made proprietary, but
the LGPL does permit proprietary programs to link to the library.
The most popular OSS/FS license by far is the GPL.
For example, Freshmeat.net reported on April 4, 2002
that 71.85% of the 25,286 software branches (packages) it tracked
are GPL-licensed (the next two most popular were LGPL, 4.47%,
and the BSD licenses, 4.17%).
Sourceforge.net reported on April 4, 2002 that the GPL accounted
for 73% of the 23,651 ``open source'' projects it hosted
(next most popular were the LGPL, 10%, and the BSD licenses, 7%).
In my paper
More than a Gigabuck:
Estimating GNU/Linux's Size,
I found that Red Hat Linux, one of the most popular GNU/Linux distributions,
had over 30 million physical source lines of code in version 7.1,
and that 50.36% of the lines of code were licensed solely
under the GPL (the next most common were the MIT license, 8.28%,
and the LGPL, 7.64%).
If you consider the lines that are dual licensed
(licensed under both the GPL and another license, allowing
users and developers to pick the license to use),
the total lines of code under the GPL accounts for 55.3% of the total.
on GPL compatibility discusses these figures further.
The popularity of the GPL is easy to explain, indeed,
for many OSS/FS projects the GPL is a good license.
An OSS/FS program using a non-copylefting
license like the MIT or BSD-new license
can be taken by a large company, extended in incompatible ways,
and made proprietary .
Over time the proprietary version may have so many
features needed by customers (or be incompatible with the original)
that all users, including the original developers, have to buy and become
dependent on that other company for what was originally the original
This technique is sometimes called "embrace, extend, extinguish".
Whether or not this is a problem depends, of course, on the goals of
the program developers.
A program licensed under the GPL or LGPL, which are copylefting licenses,
has a much lower risk of this occurring (again, program developers
may not perceive this as a risk).
Many people writing libraries want proprietary programs to be able to call
them, so for them the LGPL is a popular choice.
Note that a GPL or LGPL program can be used for commercial gain - you just
can't distribute binaries without distributing their source code.
Of course, if it's your desire that people be able modify the code
and create a proprietary version of it,
then a non-copylefting license should be used instead
(in that case, I'd suggest using the MIT license, which is simpler and clearer
than the BSD licenses).
Some projects are "dual licensed", that is, they are available under multiple
There are legions of articles on licenses, some quite heated.
Evan Leibovitch wrote three columns about them at ZDNet:
(Fatal flaw in BSD?,
Is the GPL really "user hostile"?
When you have Right on your side (or Left, as the case may be),
thoughtful piece by Jason Earl
on why some BSD advocates are hostile to the GPL.
A posting by Morris McGee
briefly contrasts the GPL and BSD approaches, arguing that both are needed
for OSS/FS development.
Sadly, some of it degenerates into name-calling, with Microsoft calling the
GPL a "virus"; a counter-claim is that the
GPL is a "vaccine against proprietary vendor lock-in".
However, it is true that
licenses are important, because they set the rules for future users and
developers, and any license will restrict what one group or another can do.
Most OSS/FS developers shouldn't create their own licenses; creating
a good license requires a good lawyer, and the probability of
unintentional incompatibility is great.
Even large organizations are usually poorly served by creating their own
license, since doing so will greatly reduce the amount of possible code reuse
and the size of developers willing to aid the project.
In summary, if you want to develop OSS/FS software,
consider the GPL for applications, the LGPL for libraries (if you want
proprietary applications to call it), and the MIT license if you want your
code incorporated into others' proprietary code.
The BSD-new license is a reasonable alternative to the MIT license.
In particular, it's unwise to create an OSS/FS project using a license
incompatible with the GPL, because such a license bars code sharing with a vast
amount of OSS/FS software;
see my article for more information on
OSS/FS developers should select a GPL-compatible license.
The LGPL, MIT, and BSD-new licenses are compatible with the GPL.
Here are some especially useful descriptions of open source/free software,
including philosophical approaches, how it's used in practice, history,
and so on:

This is a lot less well-known, but it provides useful commentary.
It's possible to read a number of political approaches into OSS/FS;
at one time some tried to claim that open source was essentially communistic.

This prompted a letter by Bruce Perens and many other OSS/FS leaders
Free Software Leaders Stand Together.
This letter explains, for example,
that ``the business model of Open Source
is to reduce the cost of software development and maintenance by distributing
it among many collaborators.
The success of the Open Source model arises from
copyright holders relaxing their control in exchange for
more and better collaboration.
Developers allow their software to be freely redistributed and modified,
asking only for the same privileges in return.''
Several of these documents are available as a single collection titled
The Open Source Reader; I suggest looking at this if you want to
print a collection of works directly from the web.
A quick summary about open source is the
UK's Parliamentary Office of Science and Technology Postnote #242
(June 2005) on open source software.

Major OSS/FS projects include:
A great deal of documentation is available at the
Linux Documentation Project (LDP).
- Linux kernel,
- Apache (web server),
- Samba (supports interoperability with Windows clients by acting as a Windows file and print server),
- GNOME (a desktop environment),
- KDE (also a desktop environment),
- The GIMP (bitmapped image editor),
- MySQL (database emphasizing speed),
- PostgreSQL (database emphasizing functionality),
- PHP (hypertext preprocessor used for web development),
- Mailman (mailing list manager),
- XFree86 (graphics infrastructure which implements the X window system),
- bind (domain naming service, a critical Internet infrastructure service),
- GNU Compiler Collection (GCC, a suite of compilation tools for C, C++, and several other languages),
- Perl (programming/scripting language),
- Python (another programming/scripting language),
- Mozilla (web browser and email client),
- OpenOffice.org (office suite, including word processor, spreadsheet, and presentation software),
- the open source BSD Operating systems (FreeBSD (general purpose), OpenBSD (security-focused), NetBSD (portability-focused)).
A number of up and coming projects are at an alpha or beta level.
Some projects that have the potential to be very important,
have running code, and are working toward more functionality or stability
include the following:
Wine (a program to allow Windows programs
to run on Unix-like systems,
AbiWord (a word processor),
KOffice (office suite),
GnuCash (money management).
Web projects around the world often use

Thus, ``Linux distributors'' sprung up, who do that work and sell
support, extra services, and so on.
Major distributions of GNU/Linux include:
Red Hat (#1 in the U.S. by most measures),
Ubuntu (a derivative of Debian that is one of the widely-used desktop distributions worldwide),
Debian (#1 non-commercial distribution),
Novell/SuSE (a major force in Europe),
there are many others.
If you're just starting up, I'd suggest trying out
Fedora (sponsored by Red Hat) and
It's tricky to figure out the market share of GNU/Linux distributions.
An IDC study of copies of GNU/Linux sold in 1999
holds huge Linux lead, rivals growing)
Red Hat shipped 48% and SuSE sold 15%.
However, while the market grew 89%, Red Hat's share grew only 69%,
suggesting that Red Hat will have more competition ahead.
The fundamental failure of these numbers is that they only count sales.
Debian is not usually "sold" in the traditional manner.
A copy of a Linux distribution
can in many cases be downloaded for free (see
LinuxISO.org for one source), and/or
installed on as many computers as you wish.
Thus, this measure is useful to show that Red Hat is widely used, but
it's less useful in showing true market shares.
One good source for information on distributions is
for a quick introduction, see its page
The Linux Distribution Game.
Open source / free software is a community and culture, not just an idea.
Thus, you can get news and cultural information from some of the following:
Linux Weekly News (LWN), in my opinion one of the
best news sources; the summarized weekly news comes out every Thursday,
but they release news as it happens.
Other useful news sources include
LXer (pronounced Elexer, it tries to
link to any related articles on other sites),
concentrates on security-related information.
Honorable mentions go to
Linux Today (which tries to
link to every related article on other sites),
Open for Business, and
ZDNet.com's Open Source blog.
The best source for news specific to the Linux kernel (in my opinion) is
Kernel Traffic, which provides a
weekly summary of the linux-kernel mailing list
linux-kernel mailing list FAQ
for general information about this).
Another useful site about the Linux kernel is the

Programmers fear that their work would be used in a manner
they did not support, and companies fear that their work would be used

Some are experimenting with applying open source/free software approaches to
areas other than software and its documentation.
Even many OSS/FS leaders are skeptical, since the attributes of software

if it doesn't work in these other areas people might unreasonably assume it
can't work in software either.
Still, it will be interesting to see the results of these experiments.
