PGObject::Simple::Role provides an interface to the PGObject service locator for Moo and Moose Perl classes. This service locator is intended to integrate Perl objects with PostgreSQL user-defined functions, and this uses the "simple" mapping approach. Between PGObject::Simple::Rrole and PGObject::Util::DBMethod, it is possible to write fully-declarative classes in which all calculation logic is handed off to database functions.
KaarPux is aimed at developers who want to build and explore a Linux distribution where they have complete control over the build process. The build process, as well as each package, are described in simple "YAML" files, which are then transformed into shell scripts used to build KaarPux.
debcheckroot is a tool that retrieves file checksums online or from read only media. It provides trusted verification of your root file system at least as far as you can trust your Internet connection or your verification medium (DVD, BD, etc.). Unlike debsums, it doesn't rely on locally stored md5sums which can be modified by an attacker along with the files themselves. It also provides cleaner and better structured output, and can spot files added to your system by someone else.
tblutils is a collection of several utilities for working with tabular text files: data written in plain text, with one row per line and columns separated by a common character (usually TAB or semicolon). It complements the usual Unix tools like cut and paste by providing enhanced versions that support column labels through-out, so that you can extract columns by name (tblcut), filter data using a mathematical expression (tblfilter), re-order columns without caring about the column index (tblcsort), join multiple files on a common index without having to pre-sort them (tblmerge), and much more.
RecDB is a recommendation engine built entirely inside PostgreSQL 9.2. It allows application developers to build recommendation applications using a wide variety of built-in recommendation algorithms such as user-user collaborative filtering, item-item collaborative filtering, and singular value decomposition. Applications powered by RecDB can produce online and flexible personalized recommendations to end-users. It is easily used and configured and allows novice developers to define a variety of recommenders that fits their application's needs in few lines of SQL. It can seamlessly integrate recommendation functionality with traditional database operations.
