DBIx::NoSQL is a layer over DBI that presents a NoSQLish way to store and retrieve data. It does this by using a table called __Store__. Once connected to a database, it will detect if this table is missing and create it if necessary. When writing data to the store, the data (a HASH reference) is first serialized using JSON and then inserted/updated via DBIx::Class to (currently) an SQLite backend. Retrieving data from the store is done by key lookup or by searching an SQL-based index. Once found, the data is deserialized via JSON and returned.

DBIx::Simple module aims to be a simplified object oriented interface to Perl DBI. From its description ... Query preparation and execution are combined in a single method, the result object (which is a wrapper around the statement handle) provides easy row-by-row and slurping methods. The "query" method returns either a result object, or a dummy object. The dummy object returns undef (or an empty list) for all methods and when used in boolean context, is false. The dummy object lets you postpone (or skip) error checking, but it also makes immediate error check simply " $db->query(...) or die $db->error".

RRDtool refers to round robin database tool. Round robin databases have a fixed number of data points in them and contain a pointer to the current element. Since the databases have a fixed number of data points the database size doesn't change after creation. RRDtool allows you to define a set of archives which consolidate the primary data points in higher granularity. RRDtool is specialized for time series data and can be used to create RRD files, update RRDs, retreive data from RRDs, and generate graphs from the databases. This module provides a POE wrapper around the rrdtool command line interface.

PgAccess is a pretty GUI (Graphical User Interface) for the open source database PostgreSQL. PgAccess is a cross-platform database management tool for PostgreSQL, written in Tcl/Tk. There are active efforts to turn it into a tool for writing applications that can work in a distributed client-server model (a central PostgreSQL database and remote clients). PgAccess was originally written by Constantin Teodorescu using Visual Tcl, "the best tool for developing Tcl/Tk applications I've ever seen." It is currently managed by the developers at BSDforge.com.

HyperSQL HSQLDB is the leading SQL relational database engine written in Java. It has a JDBC driver and supports a rich subset of ANSI-92 SQL (BNF tree format) plus SQL 99 and 2003 enhancements. It offers a small (less than 100k in one version for applets), fast database engine which offers both in-memory and disk-based tables and supports embedded and server modes. Additionally, it includes tools such as a minimal web server, in-memory query and management tools (can be run as applets) and a number of demonstration examples.

A slider for the Xfce panel that can be used to adjust and/or monitor any numeric variable. You set whatever "variable" this is by setting an adjust command which will run when the slider is clicked or scrolled. An option is provided to pass the value of the slider (the fraction times an adjustable normalization factor) to the command. You get the value of the "variable" by setting a sychronize command. The command should return a numeric value and this value will be regarded as a fraction of a second adjustable normalization factor.

CFFI, the Common Foreign Function Interface, purports to be a portable foreign function interface for Common Lisp. The CFFI library is composed of a Lisp-implementation-specific backend in the CFFI-SYS package, and a portable frontend in the CFFI package. The CFFI-SYS backend package defines a low-level interface to the native FFI support in the Lisp implementation. It offers operators for allocating and dereferencing foreign memory, calling foreign functions, and loading shared libraries. The CFFI frontend provides a declarative interface for defining foreign functions, structures, typedefs, enumerated types, etc. It is implemented in portable ANSI CL making use of the low-level operators exported by CFFI-SYS.

Log::Dispatch is a suite of OO modules for logging messages to multiple outputs, each of which can have a minimum and maximum log level. It is designed to be easily subclassed, both for creating a new dispatcher object and particularly for creating new outputs. It also allows both global (dispatcher level) and local (logging object) message formatting callbacks which allows greater flexibility and should reduce the need for subclassing. Subclassing is only needed to send a message to a different output, not to change the message format.

A program that takes as input a series of C source files and produces a LaTeX or HTML document containing a cross reference of the files/functions/variables in the program, including documentation taken from suitably formatted source code comments. The documentation is stored in the C source file in specially formatted comments, making it simple to maintain. The cross referencing includes lists of functions called, callers of each function, usage of global variables, header file inclusion, macro definitions and type definitions. Works for ANSI C, including a few gcc extensions.

Termbox is a library that provides a minimalistic API which allows the programmer to write text-based user interfaces. The library is crossplatform and has both terminal-based implementations on *nix operating systems and a winapi console based implementation for Windows operating systems. The basic idea is an abstraction of the greatest common subset of features available on all major terminals and other terminal-like APIs in a minimalistic fashion. Small API means it is easy to implement, test, maintain and learn it, that's what makes the termbox a distinct library in its area.
