deco is a command-line program that, together with the deco-archive package, allows you to extract dozens of popular archive file formats. It has a consistent interface ("deco 1.tar.bz2 2.rar 3.zip 4.flac 5.deb") and consistent behavior (never deleting archives after extraction and extracting relative to the current working directory, just verbosely enough, all unless explicitly requested otherwise). It creates an extraction directory if there is more than one file or directory at the archive top level, and it is able to fix strange permissions.
MySqueaks is a PHP class that allows you to create MySQL statements with the flexibility of OOP and throws in a simple database interface as well. This means that you can create PHP objects to represent your database tables and use the various methods provided to select, update, or delete data. This also means that instead of having to write out a very long SQL query, you can simply convert the representation into a series of "steps", which can be easier to understand and debug.
error_log feed is a PHP script that provides a feed with one alert for each line found on the error_log files of a chosen directory and its subdirectories. It's intended for webmasters that want to know, effortlessly, the warning and error messages caused by their own scripts on their Apache + PHP hosted Web sites.
jresolver is a lightweight domain name resolver library written in pure Java. It is what RFC1034 describes as a stub resolver, i.e. it uses a single nameserver to do the hard work of resolving its queries. It operates using UDP as a transport, and has support for multithreaded querying and a robust resend and timeout mechanism.
Ctpp is the C99-compatible C preprocessor of the Ctalk language, which provides object oriented extensions for C. The preprocessor is compatible with GNU cpp and provides extensions like macro expansion in warning and error messages, saving expanded macros to files, and built-in symbol definition for many command line options. You can download the preprocessor separately while Ctalk is between versions for development.
