What they looking for? 
We are looking for people to:
- Give feedback (enter/advice)
- Writing or updating the documentation
- Help new users
- Operative project to other people
- Test the code and report if there are bugs (errors)
- Fix errors (bugs)
- Provide advice to specific features (development)
- Writing and updating software
- Make "artwork"
- Translate into multiple languages
- Anything you see that need your help

Comparison With MS. Office
- Free and paid
- OpenOffice rather slow if it must open a document that uses the complex format of Microsoft.
- OpenOffice support older computers
- OpenOffice is available as a portable application
- Security: depending on the OS

 2. GIMP




History 
- The GNU Image Manipulation Program (GIMP) is software for manipulation of raster-based graphics.
- running on the GNOME desktop
- released with license GNU General Public License.
- GIMP was originally developed for the X 11 desktop that runs on a Unix platform.
- It's been ported to multiple platforms of other operasiyang systems i.e. MS Windows and Mac OS.
- The graph generated by GIMP XCF format is stored and can be exported to various image formats such as bmp, jpg, gif, pdf, png, svg, tiff, and many more.
- GIMP provides a lot of plugins which facilitates in processing the images (image) quickly.

Features 
- As a program for coloring.
- expert quality photo retouching program.
- An online application for batch processing system.
- A product for image renderer.
- An application image format converter. and many more.
- In addition, GIMP also provides export/import the Photoshop file. So that can edit the image files already made in Windows.

Specification Of GIMP 
File size: 11.6 MB (download), 18-36MB (attached).
Publisher: PortableApps.com (John t. Haller) and the GIMP team.
Date updated: July 15, 2007.
Operating system: Windows 98/me/2000/XP/Vista
License: Free/Open source (GPL).

Comparison with similar applications 
GIMP VS PS. 
- GIMP: supports all OS vs. Ps: only for Windows and Mac OS
- GIMP: free vs. Ps: cheap
- GIMP: computer specifications low vs. Ps: need a high computer specifications
- GIMP: it only supports 8 bits-per-channel vs. Ps: supports up to 64-bit perchannel.

 3. Octave



History
- An application programming with high-level language for numerical computations
- Interface in the form of command line to complete a linear and nonlinear numerically.
- Written firstly by John w. Eaton and colleagues.
- First introduced in 1988 as the applications used on chemical reactor that was written by James b. Rawlings of the University of Wisconsin-Madison and John g. Ekerdt of the University of Texas.
- The developer of this application started in 1992.
- Version of Alpa issued on 4 January 1993 Version 1.0 — released on February 7, 1994.
- Review of applications made on July 1997 by the Linux Journal.

Features 
- Resolving numerical linear algebra
- Find solutions for nonlinear equations,
- Bringing together the various functions
- The manipulation of polynomials,
- Integration of differential and differential-algebraic equations.
- Easy to use and evolved through "user-defined functions" which are written by Octave's programming language
- Can be combined dynamically the modules written in C++, C, Fortran, or other programming languages.

Comparison With MatLab
- Have a syntax that is similar to Matlab.
- Octave give look rather difficult to see compared to the matlab helpnya has compiled in accordance with the message.
- Octave doesn't have a feature to manipulate images such as those in Matlab.

4. R



History
- R is a programming language and software for statistical analysis and graphing.
- R created by Ross Ihaka and Robert Gentleman at the University of Auckland, New Zealand, developed by the R Development Core Team, where Chambers is its members.
- R is named in part after the names of two of the creators (Robert Gentleman and Ross Ihaka), and partly from the name S.

Features
- For data manipulation, calculation of funds display visula/grafikal An effective Data handling and storage areas
- Calculation of repeated use of matrices
- Integrated Applications for the processing of data analysis
- Display good analysis data for grafikal appear visually (on screen) or hardcopy.
- Very good, easy and effective programming that includes: conditionals, loops, user
- defined recursive functions and input and output facilities.
