open source software and open technology standards. The SurveyOS Project

currently devotes programming efforts and source code to the open source

desktop GIS program known as OpenJUMP. It also dedicates a set of AutoLISP

source code via the GPL that can be used to add surveying and geospatial

functionality to other software.</p>

<p>SWIG is a software development tool that connects programs written in C

and C++ with a variety of high-level programming languages.  SWIG is used

with different types of languages including common scripting languages

such as Perl, PHP, Python, Tcl and Ruby. The list of supported languages

also includes C#, Java, Lua, Octave and R amongst others. SWIG is most

commonly used to create high-level interpreted or compiled programming

environments, user interfaces, and as a tool for testing and prototyping

C/C++ software.</p>

<p>Teaching Open Source (TOS) exists to support instructors and FLOSS community

members who desire to support student involvement in FLOSS projects

within academic institutions.  The TOS community is supported by a web

site, mailing list, and planet and welcomes new community members from

both academia and FLOSS projects.</p>

<p>Twisted is an event-based engine for Internet applications, written in

Python. Twisted supports TCP, SSL and TLS, UDP, Unix sockets, multicast,

and serial ports. It also includes a Web server, an SMTP/POP3 server, a

telnet server, an SSH server, an IRC server, a DNS server, and of course

APIs for creating new protocols. It supports integration with GTK+ 2, Qt,

Tkinter, wxPython, Mac OS X (PyObjC) and Win32 event loops.</p>

<p>uClibc (pronounced yew-see-lib-see) is a C library

for developing embedded Linux systems. It is much smaller than the GNU

C Library, but nearly all applications supported by glibc also work

perfectly with uClibc. Porting applications from glibc to uClibc

typically involves just recompiling the source code. uClibc even

supports shared libraries and threading. It currently runs on standard

Linux and MMU-less (also known as uClinux) systems with support for

alpha, ARM, cris, i386, i960, h8300, m68k, mips/mipsel, PowerPC, SH,

SPARC, and v850 processors.</p>

<p>Wine is an Open Source implementation of the Windows API on top of

X and Unix.  It is a compatibility layer for running Windows

programs. Wine does not require Microsoft Windows, as it is a

completely free alternative implementation of the Windows API

consisting of 100% non-Microsoft code, however Wine can optionally use

native Windows DLLs if they are available. Wine provides both a

development toolkit for porting Windows source code to Unix as well as

a program loader, allowing many unmodified Windows programs to run on

x86-based Unixes, including Linux, Mac OS X, FreeBSD, and Solaris.</p>
