FreeON is an experimental, open source (GPL) suite of programs for linear scaling quantum chemistry. It is highly modular, and has been written from scratch for N-scaling SCF theory in Fortran95 and C. Platform independent I/O is supported with HDF5. FreeON should compile with most modern Linux distributions and OS X. FreeON performs Hartree-Fock, pure Density Functional, and hybrid HF/DFT calculations (e.g. B3LYP) in a Cartesian-Gaussian LCAO basis. All algorithms are O(N) or O(N log N) for non-metallic systems. Periodic boundary conditions in 1, 2 and 3 dimensions have been implemented through the Lorentz field (Γ-point), and an internal coordinate geometry optimizer allows full (atom+cell) relaxation using analytic derivatives. Effective core potentials for energies and forces have been...

hxCurl is a simple binding of the famous libCurl library for the haXe language.,

RIDE is a multi-flow HPC paradigm and the system that implements it. It aims to beat MPI and OpenMP for simplicity of use. It also beats approaches such as MapReduce and Task Flow because RIDE solves wider range of tasks.

Concurrency Kit provides a plethora of concurrency primitives, safe memory reclamation mechanisms and lock-less and lock-free data structures designed to aid in the design and implementation of high performance concurrent systems. It is designed to minimize dependencies on operating system-specific interfaces and most of the interface relies only on a strict subset of the standard library and more popular compiler extensions....

ldap2dns reduces all kind of administration overhead: No more flat file editing, no more zone file editing. After having installed ldap2dns, the administrator only has to modify the data stored in the LDAP directory.

Optionally access control can be configured for each zone, GUIs can be more easily implemented, and add all other kind of zone and resource record information can be managed without interfering with the DNS server....

ncdc is a modern and lightweight Direct Connect client with a friendly text-mode interface.

The sigrok project aims at creating a portable, cross-platform, Free/Libre/Open-Source signal analysis software suite that supports various device types, such as logic analyzers, MSOs, oscilloscopes, multimeters, LCR meters, sound level meters, thermometers, anemometers, light meters, dataloggers, function generators, power supplies, GPIB interfaces, and more....

Includes a tutorial and an automated test collector utility....

32bit, protected mode operating system, which wrote in the C and assembly,

E-mail is the 'flow' in the work flow of many people. Consequently, one spends a lot of time searching for old e-mails, to dig up some important piece of information. With people having tens of thousands of e-mails (or more), this is becoming harder and harder. How to find that one e-mail in an evergrowing haystack?...
