This library provides a collection of (macro-based) functions for performing safe integer operations across platform and architecture with a straightforward API. It supports two modes of use: header-only and linked dynamic library. The linked, dynamic library supplies a format-string based interface which is in pre-alpha. The header-only mode supplies integer and sign overflow and underflow pre-condition checks using checks derived from the CERT secure coding guide. The checks do not rely on twos complement arithmetic and should not at any point perform an arithmetic operations that may overflow. It also performs basic type agreement checks to ensure that the macros are being used (somewhat) correctly.

A simple binary file format for storing arbitrary meta and user data. A meta archive uses a simple binary file format to store both meta and user data together in a single file. A mar file may be suitable in situations where a full-scale database is not. Both the mar library and the accompanying utility are written in C with the intention of porting to many platforms.

Intel Threading Building Blocks (TBB) offers a rich and complete approach to expressing parallelism in a C++ program. It is a library that helps you take advantage of multi-core processor performance without having to be a threading expert. Threading Building Blocks is not just a threads-replacement library. It represents a higher-level, task-based parallelism that abstracts platform details and threading mechanism for performance and scalability.

FEAPpv is a general purpose finite element analysis program which is designed for research and educational use. The program is described in the references: The Finite Element Method, 6th ed., Vols. 1 and 2, by O.C. Zienkiewicz and R.L. Taylor, Elsevier, Oxford, 2005. FEAPpv is designed to be compatible for compilation in Unix/Linux and Windows PC environments. No support on use of the program will be provided.

Tinyarrays are similar to NumPy arrays, but optimized for small sizes. Common operations on very small arrays are to 3-7 times faster than with NumPy (with NumPy 1.6 it used to be up to 35 times), and 3 times less memory is used to store them. Tinyarrays are useful if you need many small arrays of numbers, and cannot combine them into a few large ones. (The resulting code is still much slower than C, but it may now be fast enough.)

This library can be used to easily access XML data of the iso-codes package. It will provide an abstraction layer to handle both the version 3 and the upcoming version 4 of iso-codes. Moreover, all available translations can be used as well. This library makes use of the GObject introspection features, so that it is accessible from a variety of programming languages, for example C, Vala, Ruby, Python, Perl, Lua, JavaScript, PHP and many more.

LINGOT is a musical instrument tuner. It's accurate, easy to use, and highly configurable. Originally conceived to tune electric guitars, it can now be used to tune other instruments. It looks like an analogue tuner, with a gauge indicating the relative shift to a certain note, found automatically as the closest note to the estimated frequency.

One of the drawbacks for using Perl's native array is that it is a memory-hog. Normally it takes 20 bytes a scalar (16 bytes for scalar + overhead). This can be a problem when you need to handle millions of numbers in-memory. This module saves memory in exchange for speed.

Fortunelock is a "keep it simple, stupid" program to lock a terminal while showing fortunes. It was designed to be as small and simple as possible and therefore does not support PAM, NIS, shadow passwords or even regular passwords: the user must enter a lock password to lock the terminal.

Text::Decorator is a framework for marking up plain text into various formats by applying a chain of filters. For instance, you might apply a filter which will cause URIs in text to be presented as links if the text is exported as HTML.
