Asterisk The Open Source PBX
Asterisk The Open Source PBX
33 min - Jan 7, 2007
Asterisk is a free software / open-source software implementation of a telephone private branch exchange (PBX). Like any PBX, it allows a number of attached telephones to make calls to one another, and to connect to other telephone services including the public switched telephone network (PSTN). "Its name comes from the asterisk symbol, *, which in Unix (including Linux) and DOS environments represents a wildcard, matching any sequence of characters in a filename."
Asterisk is released under a dual license scheme, the free software license being the GNU General Public License (GPL), the other being a commercial license as to allow closed/patented code, such as the G.729 codec to work with the system (although the G729 codec may work with the free or commercial versions). Mark Spencer of Digium originally created Asterisk. (http://en.wikipedia.org/wiki/Asterisk_PBX)

Open Source Software (OSS) and the DoD
Open Source Software (OSS) and the DoD
1 hr 32 min - Feb 14, 2008
Open source software (OSS) has become widespread, but there are many misconceptions about it - resulting in numerous missed opportunities. This presentation will clarify what OSS is (and isn't), rebut common misunderstandings about OSS, discuss the relationship of OSS and security, discuss how to find and evaluate OSS, and explain OSS licensing (including how to combine products and select a license). It will show why nearly all extant OSS is COTS software, and thus why it's illegal (as well as foolish) to ignore OSS options.
David A. Wheeler (http://www.dwheeler.com/) specializes in software development practices for secure systems. His expertise includes vulnerability assessment, software standards, and free-libre / open source software (FLOSS or OSS). He is widely cited as an expert on open source software; his influential articles include "Open Source Software (OSS) in U.S. Government Acquisitions", "Why OSS/FS? Look at the Numbers!", "'Commercial' is not the opposite of FLOSS", and "How to Evaluate OSS/FS Programs". He has served as a lead validator for the Common Criteria, and is the author of the books "Software Inspection: An Industry Best Practice" (IEEE Computer Society Press), "Ada 95: The Lovelace Tutorial" (Springer-Verlag), and "Secure Programming for Linux and Unix HOWTO" (self-published).
