Free 2.0.0 software for linux

Yed is an Open Source research project; its mission is the developing of a C software library made of modules ( objects )iUnknown.org instanceable in according to the main paradigms of Object Oriented Programming: incapsulation,data hiding and inheritance.

Yed core acts at only C compiler preprocessing level, using particular macros; therefore, using Yed objects is transparent to the C compiler, and it is not necessary to develope additional " translation" tools that have to be run before compiling.

Yed library contains objects that handle XML files, FTP connections, file system operations and so on.

GKSu is a library that provides a Gtk+ frontend to su and sudo. GKsu project supports login shells and preserving environment when acting as a su frontend.
It is useful to menu items or other graphical programs that need to ask a users password to run another program as another user.
Enhancements:
- Since the last 1.3 version, this is the first high profile stable release of the gksu application.
- Together with the changes of libgksu, gksu now is able to use a global gconf setting to use su or sudo as the backend, handles "wrong password" better, and other things.
- An optional nautilus addon was added, which adds an "Open as administrator" menu item to the nautilus context menu for various files and folders.
- This menu item will open that file using the application that handles its type by default using gksu.

Lcal is a multi-platform (Unix/Linux, DOS, DOS+DJGPP, Windows+Cygwin) program which generates full-year PostScript lunar (moon phase) calendars in a 2-page format, a compressed 1-page format, or an odd-days-only 1-page format.
Lcal is run from the command line.
Enhancements:
- Added a brand new calendar format (see Figure 6, below). This new format is a 1-page format showing only the odd days in a month. This allows an entire month to be displayed on a single US letter-sized page without having to compress the output, as is currently done with the -S option. (The original method of 1-page output [using -S] will still be supported too.)
- Added support for DOS (includes DOS under Windows) and DOS+DJGPP build environments. Clarified that DOS/Windows+Cygwin is supported too.
- Removed support for Vax/VMS and Amiga.
- Fixed the timezone bugs as described in the Bugs/Problems in (now-obsolete) Pcal 4.9.1 section (see the link in the Notes On Obsolete Releases of Pcal section, above). (These bugs apply to both pcal and lcal.)
- Fixed the longstanding problem whereby the PostScript output did not include page enumerations, thereby preventing PostScript viewer applications (e.g. gv) from properly paging between the first and second pages on the 2-page calendar format.
- Completely overhauled to eliminate the dependency on the external PostScript source file and on the program to perform PostScript to C header file conversion. This substantially reduces overall source code size. Furthermore, it simplifies and more clearly highlights the differences between portrait and landscape orientations.

BOXit is a small logic game for occasionally. Clear the playing field as far as possible, by dragging same-colored or equivalent tokens one over another, if they are in the same row or column on the playing field.

This is one of the games that are quick to learn but hard to handle. If you have fun in fast pace puzzling, BOXit is just right for you.

BOXit 2.0 is free software in the purposes of the Gnu GPL version 2 or newer.

Hypres goal of the Scalable Linear Solvers project is to develop scalable algorithms and software for solving large, sparse linear systems of equations on parallel computers.
The primary software product is hypre, a library of high performance preconditioners that features parallel multigrid methods for both structured and unstructured grid problems.
The problems of interest arise in the simulation codes being developed at LLNL and elsewhere to study physical phenomena in the defense, environmental, energy, and biological sciences.
Although parallel processing is necessary for the numerical solution of these problems, alone it is not sufficient. Scalable numerical algorithms are also required. By "scalable" we generally mean the ability to use additional computational resources effectively to solve increasingly larger problems. Many factors contribute to scalability, including the architecture of the parallel computer and the parallel implementation of the algorithm. However, one important issue is often overlooked: the scalability of the algorithm itself. Here, scalability is a description of how the total computational work requirements grow with problem size, which can be discussed independent of the computing platform.
Many of the algorithms used in todays simulation codes are based on yesterdays unscalable technology. This means that the work required to solve increasingly larger problems grows much faster than linearly (the optimal rate). The use of scalable algorithms can decrease simulation times by several orders of magnitude, thus reducing a two-day run on an MPP to 30 minutes. Furthermore, the codes that use this technology are limited only by the size of the machines memory because they are able to effectively exploit additional computer resources to solve huge problems.
Scalable algorithms enable the application scientist to both pose and answer new questions. For example, if a given simulation (with a particular resolution) takes several days to run, and a refined (i.e., more accurate) model would take much longer, the application scientist may forgo the larger, higher fidelity simulation. He or she also may be forced to narrow the scope of a parameter study because each run takes too long. By decreasing the execution time, a scalable algorithm allows the scientist to do more simulations at higher resolutions.
Enhancements:
- Fixes and updates to documentation to bring it up to date.
- Minor cleanups.

Lasso is a free software C library aiming to implement the Liberty Alliance standards; Lasso defines processes for federated identities, single sign-on and related protocols.
Lasso is built on top of libxml2, XMLSec and OpenSSL and is licensed under the GNU General Public License (with an OpenSSL exception).
We strongly recommend the use of the GNU General Public License each time it is possible. But for proprietary projects, that wouldnt want to use it, we designed a commercial license.
Lasso first focused on implementing the Liberty Alliance ID-FF 1.2 protocols. Work is now underway to provide backward compatibility with ID-FF 1.1 implementations and to implement support for ID-WSF 1.0.
SWIG is used to provide high-level bindings for other languages. Currently tested and distributed bindings are Python, Perl, Java and PHP as well as preliminary .NET assemblies (for C# and the .NET runtime environment).
It is primarly developed on GNU/Linux and works on many UNIX environments (including Apple MacOS X) and on Microsoft Windows.
Enhancements:
- SAMLv2 support was completed, passing a conformance event organized by the Liberty Alliance.
- Memory leaks and potential segmentation faults were fixed.
