Open Admin for Schools is a School Administration Program. It is a freely available, open source software package and is licensed under the GNU General Public License.
Open Administration for Schools project is entirely web based and can run from a centrally located division wide server or a single computer in a school. It is designed to support an entire division on one or more central computers but can also work just fine for a single school.
Currently several school divisions use this approach and have 15+ schools on a single central server. This is because it is designed to be lightweight both in server resource requirements and in communication bandwidth.
It is secure. Each school has two or more virtual websites and each is protected with password(s). One site, the admin site, is used by the school office and another, the teacher site, is used by teachers in the classroom.
The teacher site also has password access for entering attendance by teachers and also uses cookies that expire in a short period, further limiting access. Another site, a parent/student site, is controlled by parent/student userids and passwords. A fourth virtual site may be used by school liason officers from outside agencies to give them a slightly different access to school information. (Community Schools)
Main features:
- Demographics - It stores student and family information that can be viewed and printed in a variety of ways.
- Attendance - Attendance can be entered either by secretaries in the school office or by teachers in the classroom. It features the ability to do different numbers of periods per day for elementary grades vs high school and middle years. This will allow elementary classes to have 2 classes per day (AM/PM) with a homeroom teacher while higher grades can have attendance done on a per subject period basis (and be subject based). Attendance reports are integrated with report cards/progress reports. A variety of attendance reports are available. A variety of attendance entry methods are available for use by teachers and/or secretaries to allow it to integrate with normal school practice.
- Discipline - A simple discipline module to track student discipline events and track outcomes, etc. Behaviours may be categorized and statistical reports may be printed. Enrollment changes are also posted into this system.
- Report Card System - a flexible reporting system with per subject objectives (up to 20), integrated attendance reporting, etc. All report cards are printed as PDF reports and may include a school logo. All subjects may have unlimited length text comments, and can have any desired ordering. Attendance reporting will now do days open, days enrolled, days absent, and times late as standard.
- IEP (Special Needs) Site that is integrated at the division level that allows special needs teachers to tailor individual student programs that can be viewed from each schools teacher site. This includes the ability to add student medical history, testing done, student teams (and responsibilities), and objectives chosen from lists of thousands, categorized in a variety of ways. There can be up to 32 objectives per subject and each subject is specific to that particular child. His/her program would consist of a variety of subjects in areas such as fine motor control, etc.
- This system can generate progress reports (for use with the report card system) as well as a comprehensive IEP report containing the yearly plan for the child. This IEP can also viewed from the teacher site, to ensure compliance throughout the year.
- Export/Import Modules - to allow students to easily transfer schools within divisions without re-entry of demographic information. Export of data to other programs. Export of data to Provincial authorities via an automated XML based transfer mechanism.
- Saskatchewan SDS support for direct XML transfers of student demographic, subject and enrollment marks to provincial authorities.
- Online Gradebook to allow teachers to enter marks and assessments onine from school or home. It can group and weight assessment items and post directly into the report card system.
- Parent Viewing scripts to allow parents to view attendance, gradebook(where allowed), and report card marks. This is easily integrated into existing school sites.
- Upcoming: Family functions, Parent-Teacher Interview Scheduling, Wherever schools want to go...
- Further out... Multi-language support (demand for a Spanish version exists currently), Student timetabling.
Enhancements:
- A new Fees System to allow fee charging (predefined or new, with various groups), invoice printing, payments and receipts, and the ability to export summary journal transactions to an external accounting program.
- A new teacher logout to remove session data has been added.
- There is a new 70 page User Documentation PDF and a 40 page Administration Documentation PDF (also available in HTML versions).

Open Babel project is designed to pick up where Babel left off, as a cross-platform program and library designed to interconvert between many file formats used in molecular modeling and computational chemistry.
Main features:
- A huge variety of common chemical file formats, including SDF/MOL, Mol2, PDB, SMILES, XYZ, CML... (details)
- Recognition of file type based on filename extension
- Chemical MIME support
- SMARTS matcher
- Flexible atom typer
- Flexible bond typer for perception of multiple bonds from atomic coordinates
- Gasteiger partial charge calculation
- Hydrogen addition and deletion
- Isotope support, calculation of average and exact masses
- Automatic feature perception (rings, bonds, hybridization, aromaticity)
- Multiple conformer storage within molecules
- Command line conversion for multiple molecules in one file
- Command line interface
- Bitvector class
- Vector and matrix transformations
- Molecular test suite
- Open-source/Free Software under the GNU General Public License
- Cross platform (Windows, Linux, Mac OS X, SGI, Solaris, Dreamcast...)
Version restrictions:
- Generate coordinates for SMILES strings. (Meaning all coordinates will be zero when converting from a SMILES string.)
- Handle 2D->3D conversion (or vice versa).
- Handle a variety of important file formats.
Whats New in 2.1.1 Development Release:
- Improved scripting support, including dictionary-support for OBGenericData in pybel, casting from OBUnitCell, etc. Improved access to OBRings from OBMol.GetSSSR().
- Added support for descriptors (e.g., PSA, logP) from scripting interfaces.
- Added support for reading all PDB records (beyond current atom and bond connections). Records not handled directly by Open Babel are added as key/value pairs through OBPairData.
- Added a new configure flag --with-pkglibdir to allow Linux package distributors to define version-specific directories for file format plugins.
- Fixed a bug which would not output chirality information for canonical SMILES with 3D files.
- Fixed problems with new line-ending code. Now correctly reads DOS and old Mac OS files with non-UNIX line endings.
- Correctly rejects SMILES with incorrect ring closures. Thanks to Craig James for the report.
- Fixed a crash when output to canonical SMILES.
- Fixed a crash when converting from SMILES to InChI.
- Fixed a crash when reading some PDB files on Windows.
- Fixed a crash when reading invalid MDL/SDF files.
- Fixed a bug which made it impossible to read some GAMESS files.
- Fixed a problem when reading ChemDraw CDX files on Mac OS X.
- A large number of additional fixes, including some rare crashes.

GroundWork Monitor Open Source is a complete availability monitoring solution that ensures IT infrastructure uptime while identifying issues before they become real problems.

Unifies best-of-breed open source tools - Nagios*, Nmap, SNMP TT, PHP, Apache, MySQL and more — through PHP/AJAX-based components and an integrated user interface to deliver the extensible functionality you require.

Open Invaders is a fully-GPL interpretation of Taitos Space Invaders. While it is not a perfect clone, the aim of the project is to provide a feature rich clone of the famous arcade game. It features (so far) 14 levels with unique backdrops and a full soundtrack.
