The Pencil Project's unique mission is to build a free and opensource tool for making diagrams and GUI prototyping that everyone can use.

Off-the-Record (OTR) Messaging allows you to have private conversations over instant messaging by providing:

Encryption
No one else can read your instant messages.
Authentication
You are assured the correspondent is who you think it is.
Deniability
The messages you send do not have digital signatures that are checkable by a third party. Anyone can forge messages after a conversation to make them look like they came from you. However, during a conversation, your correspondent is assured the messages he sees are authentic and unmodified.
Perfect forward secrecy
If you lose control of your private keys, no previous conversation is compromised.

A new analysis of licensing data shows that not only is use of the GPL and other copyleft licenses continuing to decline, but the rate of disuse is actually accelerating.

That was the conclusion of Matthew Aslett’s analysis of recent data from Black Duck Software , which shows that while use of the GPL, LGPL, and AGPL set of copyleft licenses dominates free and open source projects, that use is still on the decline.

“The GPL family now accounts for about 57% of all open source software, compared to 61% in June,” Aslett wrote. More troubling for copyleft advocates, though, could be the projection Aslett and the 451 Group make based on the data.

“…[I]f the current rate of decline continues, we project that the GPL family of licenses will account for only 50% of all open source software by September 2012.”

Looking at the graph to which Aslett refers , you can see how that projection is a logical one to make. You can also see what developers are licensing their projects under instead: permissive licenses such as the MIT, Apache (ASL), BSD, and Ms-PL group of licenses.

Copyleft’s unique way of using copyright means the parties who may enforce are copyright holders (and their designated agents). However, the victims of the violation are typically thousands of users who have bought a product that included the GPL’d program. The goal, therefore, is to get source code that these users can actually use to compile and install the software. […]

Violators express a concern that, if they come into compliance due to my efforts, what stops others from coming to complain, in sequence, and wasting their time? I suggested that if they came into compliance all at once, on all FLOSS licenses involved, it would be easy for me to be on their side, should someone else complain.
