We regularly check various open-source projects with PVS-Studio and send analysis results to developers and usually describe them in our posts as well. Besides, we add them into our bug database. This database is posted below on this page.
The bugs are grouped according to the number of the diagnostic rule that is used to detect them. This number is given in the left column. Click on it to see the diagnostic rule description in the documentation. The right column contains a link to the corresponding error samples.
Some diagnostics haven't detected any bugs in open-source projects yet. The lower you are in the list, the more diagnostics with no error samples there will be. The reason is simple: the later a certain rule had been added, the fewer projects were analyzed with this rule included into the rule set and therefore the fewer chances for it to demonstrate its capabilities.
For the purpose of testing our C/C++ analyzer PVS-Studio, we often check various open-source projects and publish reports about bugs we have found. It is obvious that we seek projects of large sizes (hundreds of thousands of code lines), as there is little to be tested and caught in just a few dozens of files. We already had opportunities to test large collections consisting of hundreds of small open-source projects, for example sets of test samples for various SDKs and Frameworks. We are especially interested in checking such collections to see how the analyzer supports various specific code constructs, Visual C++ project subtypes, and so on.
The PVS-Studio team has analyzed over 200 open-source projects with their static code analyzer. Among them are such titles as Unreal Engine, Php, Haiku, Qt, and even Linux. In each of these projects, bugs of varying severity were detected. The team regularly reports the analysis results in their blog. Each post is a separate article of several pages, describing in detail each of the bugs found and giving recommendations on how to fix them.
The PVS-Studio team decided to go further to create a service of tips and recommendations on C/C++ usage, CppHints.com, in addition to the practice of writing articles. Within the scope of this service, the team publishes 1 recommendation/tip per day. Each publication delivers concentrated information on C/C++ programming approaches and techniques used in various situations and includes examples of correct and incorrect language use from over 200 open-source projects.

The Programming Historian is an open-access introduction to programming in Python, aimed at working historians (and other humanists) with little previous experience.
The PushButton Engine is an open-source Flash game engine. There are lots of great libaries for building Flash games; PushButton Engine makes it easier to bring them together. PushButton Engine is written in ActionScript 3, and relies on Flash 9 or higher. It officially supports Flex Builder, command line builds, and Flash CS4, and people have succesfully used it with FlashDevelop and other ActionScript development environments.
More concretely, PushButton Engine provides some useful utilities (like an XML serialization/level format, logger and other debugging tools, time management, resource manager, and more), and a component system which lets you easily package game functionality into resuable modules. The component system draws on nearly a decade of game development history - you can read about it in detail in the Components section of the manual.

Processing is an open source programming language and environment for people who want to program images, animation, and interactions. It is used by students, artists, designers, researchers, and hobbyists for learning, prototyping, and production. It is created to teach fundamentals of computer programming within a visual context and to serve as a software sketchbook and professional production tool. Processing is an alternative to proprietary software tools in the same domain.
Processing is free to download and available for GNU/Linux, Mac OS X, and Windows. Please help to release the next version!
