Codeville is a distributed Version Control System. It began with a novel idea for a merge algorithm, and has grown from there. It is designed to be easy to use, and scale from small personal projects, to very large distributed ones. If you'd like to know why there's need for new merge algorithms, consider what the lead monotone developer had to say: http://article.gmane.org/gmane.comp.version-control.monotone.devel/3264 Codeville works by creating an identifier for each change that is done, and remembering the list of all changes which have been applied to each file, and the last change which modified each line in each file. When there's a conflict, it checks to see if one of the two sides has already been applied to the other one, and if so, makes the other side win automatically. When there's a non automatically mergeable version conflict, Codeville behaves in almost exactly the same way as CVS.

I believe a lot of log processing is done too early. This module lets you defer log processing in two ways: * Defer recording of log messages until some "transaction" has completed Typically this transaction is something like an HTTP request or a cron job. Generally log messages are easier to read if they are recorded atomically and are not intermingled with log messages created by other transactions. * Defer rendering of log messages Sometimes you don't know how logs should be rendered until long after the message has been written. If you aren't sure what information you'll want to display, or you expect to display the same logs in multiple formats, it makes sense to store your logs in a highly structured format so they can be reliably parsed and processed later. This module doesn't actually write out logs! To use this module for normal logging purposes you also need a logging library.

Thread::Apartment provides an apartment threading wrapper for Perl classes. "Apartment threading" is a method for isolating an object (or object hierarchy) in its own thread, and providing external interfaces via lightweight client proxy objects. This approach is especially valuable in the Perl threads environment, which doesn't provide a direct means of passing complex, nested structure objects between threads, and for non-threadsafe legacy object architectures, e.g., Perl/Tk. By using lightweight client proxy objects that implement the Thread::Queue::Queueable interface, with Thread::Queue::Duplex objects as the communication channel between client proxies and apartment threads (or between threads in general), a more thread-friendly OO environment is provided, ala Java, i.e., the ability to pass arbitrary objects between arbitrary threads. Thread::Apartment is a fundamental component of the PSiCHE framework (http://www.presicient.com/psiche).

This is automated checker to make sure a C++ file follows Google's C++ style guide (http://google-styleguide.googlecode.com/svn/trunk/cppguide.xml). As it heavily relies on regular expressions, cpplint.py won't catch all violations of the style guide and will very occasionally report a false positive. There is a list of things we currently don't handle very well at the top of cpplint.py, and we welcome patches to improve it. The linting tool takes a list of files as input. For full usage instructions, please see the output of: ./cpplint.py --help Unit tests are provided in cpplint_unittest.py. This file can safely be ignored by end users who have downloaded this package and only want to run the lint tool.

Mozilla::PublicSuffix provides a single function that returns the public suffix of a domain name by referencing a parsed copy of Mozilla's Public Suffix List. From the official website at http://publicsuffix.org: A "public suffix" is one under which Internet users can directly register names. Some examples of public suffixes are .com, .co.uk and pvt.k12.wy.us. The Public Suffix List is a list of all known public suffixes. A copy of the official list is bundled with the distribution. As the official list continues to be updated, the bundled copy will inevitably fall out of date. Therefore, if the bundled copy of found to be over thirty days old, this distribution's installer provides the option to check for a new version of the list and download/use it if one is found.

QEMU is a FAST! processor emulator using dynamic translation to achieve good emulation speed. QEMU has two operating modes: * Full system emulation. In this mode, QEMU emulates a full system (for example a PC), including a processor and various peripherials. It can be used to launch different Operating Systems without rebooting the PC or to debug system code. * User mode emulation (Linux host only). In this mode, QEMU can launch Linux processes compiled for one CPU on another CPU. It can be used to launch the Wine Windows API emulator or to ease cross-compilation and cross-debugging. As QEMU requires no host kernel patches to run, it is very safe and easy to use. See also the preconfigured system images on http://oszoo.org/ Many live cd isos also work.

KnightCap is a chess program. The principal differences between KnightCap and other chess programs are: - KnightCap has an optional fully rendered 3D interface, giving a feel much more like an "over the board" game. - KnightCap was developed to run on a parallel distributed memory machine, although it also runs on normal Unix boxes. - KnightCap does not have an opening book---instead it keeps a file (brain.dat) of losing moves and inserts them in the hash table at the start of each search. At present it has about 1500 entries, and this makes it a pretty competitive opening player. - KnightCap learns the parameters of its evaluation function as it plays. The most dramatic example of how this helps is an experiment we conducted on FICS in which KnightCap learnt from a 1650 player to a 2100 player in just 300 games. See http://cs.anu.edu.au/people/Lex.Weaver/pub_sem/publications/knightcap.pdf for more info on its learning algorithm.

Sort files or its standard input using the bogo-sort algorithm described in the Jargon File <http://www.catb.org/~esr/jargon/>. A quote from the Jargon File 'bogo-sort' entry: ...The archetypical perversely awful algorithm (as opposed to _bubble sort_, which is merely the generic bad algorithm). _Bogo-sort_ is equivalent to repeatedly throwing a deck of cards in the air, picking them up at random, and then testing whether they are in order. It serves as a sort of canonical example of awfulness. Looking at a program and seeing a dumb algorithm, one might say "Oh, I see, this program uses _bogo-sort_." Esp. appropriate for algorithms with factorial or super-exponential running time in the average case and probabilistically infinite worst-case running time. Compare _bogus_, _brute force_, _lasherism_...
