sud (superuser daemon) permits a user to switch to root privileges and to use a suid program in a nosuid environment. It is based on a client/server model and on the ability to pass file descriptors between processes. sud permits you to choose your authentication method, and your effective credentials will be checked by using a Unix domain socket.
superGlobals is a PHP library that transparently injects into a superglobal or global variable while keeping all functionality of a regular array, but extending it with type casting and URI parsing into that array. It can use memcached for additional performance and can interact with custom DB abstractions (mostly PEAR). It may filter, cast, or validate variables as: boolean, integer, float, string, array, object, IPv4 address, IPv6 address, regular expression, URL, URL encoded string, HTML escaped string, or SQL escaped string. It is possible to pass a function name callback as a casting or validation method. Also, it is possible to pass multiple casting methods for each variable, which is useful for array processing.
svenson is a JSON generator/parser that allows you to convert JSON data sets into graphs of Java objects and vice-versa. It supports the whole range of just using collection classes for your Java object graphs or your own types or something in between, like your own types with Java properties and dynamic properties. svenson offers a set of annotations and interfaces that give you fine-grained control over how JSON is generated or parsed.
svn-dump-fast-export converts a textual representation of a Subversion repository into input suitable for git-fast-import and similar importers. Subversion repository dumps can be generated using the 'svnadmin dump' or 'svk admin dump' command. To support incremental imports, it puts a 'git-svn-id' line at the end of each commit log message if passed an URL on the command line. Empty directories and unknown properties are silently discarded. The resulting repository will generally require further processing to put each project in its own repository and to separate the history of each branch. The 'git filter-branch --subdirectory-filter' command may be useful for this purpose.
