Free online software for linux

Browseable Online Backup System (BOBS) is a complete online backup system. It uses large disks for storing backups and lets users browse and restore the files using a webbrowser.

Files are fetched from other computers and stored in directories on the computer where bobs is installed.

Two types of file stores are used:

"Current" is the files from the remote computer as they were the last time the backup was run.

"Incremental" is the files that are deleted or changed on the remote server.

When a backup is run the files that have changed or have been deleted are moved to the "incoming" dir. From here they are tagged with a date and moved to the "incremental" dir.

Users interaction:

If a user deletes or corrupts a file and need it restored they can do this by opening a browser (any browser which supports frames should be fine) and pointing it at the
backupserver where bobs is installed.

On the backupserver they can login in using a password defined by the admin. For clarity that should be the same as the one they use on the server where the file
they deleted or corrupted is/are located.

Users can browse, search and select files to restore. They cannot see the contents of the files. Only name, date and size.

When they have found the files they need and added them to the restore list, they activate the restore process and wait for files to be transferred to their server where they can access them as they would any other files.

Online Contact Sheet Creator script that generate stylish contact sheets without any fussing around in Photoshop.
You can use the script to generate contact sheets for clients (great for photographers or graphic designers), or you can use it personally for a small photo album.
You can also add Online Contact Sheet Creator to your web site to add some functionality for your visitors.
Main features:
- Online Contact Sheet Creator is easy to install, just a few simple steps and youre done!
- You select the number of images a visitor can upload for their sheet.
- A temporary file system insures that you wont max out your web hosts file size limits.
- The contact sheets look clean and professional, with each photo numbered for easy reference.

online.php analyses /var/log/ppp-usage and displays connection statistics. It also prints some information about your current PPP connection.
Well, I was inspired by the script Onlinecalc by Michael Schlenstedt (Michael@adsl4linux.de). His script is heavily based upon "calc" by Ulrich Schmitz.
Since Onlinecalc did not fit my needs, I did a complete rewrite in php.
Main features:
- reads /var/log/ppp-usage and prints a table with a row for each month.
- also calculates the values of the current connection.
- completely written in PHP.
- display connect-time as dd:hh:mm:ss
- display volumes as 123 456 789,12 MB
- displays chronologically (maybe I will change the sorting later to reverse)

Importing and exporting bookmarks from and to Opera, Netscape, Mozilla, and Internet Explorer are possible.

Sloth Online RPG is aJava Online RPG with Real-Time Action and rich 2D graphics.

Sloth Online RPG is a work in progress that will provide a fully graphical online role playing game engine. SlothORPG is coded in Java and is currently in a near playable state featuring several classes with over a thousand lines of code.

My main intentions with this project are to provide a free, fully functional, ever expanding Role Playing Engine (both client and server side) for the end user who would be playing the game. Developers would also be able to use the project as a resource on certain aspects of Java Game Programming.

Server side the project implements the NIO Networking library to create a smoother, stronger tcp/ip core. I found UDP and TCP w/ the old IO library to be unreliable and sluggish respectively. The way in which the server is structured has proven to be strong thus far.

The client side of the code features the Graphics2D Java library to provide near perfect animation without requiring a rendering device such as OpenGL or DirectX.

To summarize my entire intent for this project I basically wanted to provide an Online RPG that is functional on almost any OS that has Java installed and can run just as smooth on low end machines while still being able to feature rich 2-D graphics. The source code is clean and neat as well as commented and organized.

It is easy to read and understand for someone who has some knowledge of Java. As I write this, the project is coming along nicely and some pre-alpha local network testing has proven this. I plan to continue with this project and in the future include database integration and more of a developer-side interface.

A quick rundown of what this project includes so far: Character Creation, Smooth character animation, and fully supported tcp/ip gameplay. Chatting is also implemented.

Online Grades is the leading free-software project that allows K-12+ student grades to be posted onto a dynamic web site. Online Grades is not a web-based gradebook. Instead, it accepts grade export information from several popular gradebook software programs such as Easy Grade Pro, Gradekeeper, Misty Citys Grade Machine, and PGGP and places the grade information online securely.
Student, Teachers, Parents, and Administrators each get their own personal login into Online Grades, which allows them to see all of the grades in all of their classes. If parents have more than one student at a school or district, they only need one parent login to see the grades of all of their students.
The Online Grades software is free; there is no software cost to post your grade results online. However, to use the software, both an internet-accessible web server with PHP and access to a MySQL database are necessary. Because of these requirements, Online Grades is commonly set up and configured by a school or district tech person. If your school or district does not have the resources to set up Online Grades, you can alternatively buy hosting for your grades. Hosting is even available for individual teachers interested in using Online Grades.
Online Grades is free because the software is developed by volunteers and is in-part sponsored by the schools using the Online Grades software. Online Grades was originally based on the SourceForge project Basmati, and while backward compatibility has been maintained, Online Grades has many more features than the original Basmati grade posting software.

Online Cardgame System project is a client-server system for playing card games over the net.
OCS is a client-server cardgame system, similar to those found at Yahoo! Games and elsewhere. The server is portable and has been tested under Linux, Win32, and several unix systems. We currently have Win32 and Java clients available, and a Qt client for Linux is in development.
Games are implemented as plugin modules, so new games can be added without recompiling the server. In addition, the client is written to be unaware of the mechanics of gameplay, so it can theoretically play any games the server supports without having to know how to play them specifically.
We currently have Euchre and Spades implemented, with bot support for both games, meaning you dont need a full 4 people to play a game. We plan on implementing more games in the future.
On a side note, development of this project tends to wax and wane with our motivation and amount of schoolwork.
Enhancements:
- Massive restructure of code into more object orientated patterns
- Added daemon capability to server
- Got rid of checksumming in the protocol since TCP/IP does it internally
- Padded STRINGS in the protocol on DWORD boundaries
- Added support for loadable account managers
- Removed crypting of the password by ocsd (account managers may do it)
- Added ODBC (for windows) and mySQL (for unix) account managers (database connectivity!!)
- Modified packet classes to throw exceptions instead of returning true-false
- Created packet manager classes to queue client packets, reduces total send calls
- Implemented bots when there arent enough people to play games
- Added new command line processing capabilities as well as configuration file support
- Fixed bug that allowed a person to overwrite an account when creating that same account
- Win32 - Made server link with DLL runtime library to reduce executable size and ease DLL dependencies
- Updated messages to be sent in HTML since the main clients support it
- Created Java client which can be run as an application or as an applet
- After a client is booted from a game, they cannot join the game again until they receive an invitation
- Fixed libtidy bug which caused it to erroneously format HTML
- Euchre supports intelligent bots
- Spades supports moronic bots (the AI is horrible but allows for gameplay)
- Fixed Spades textual problem when a round was over.
- Fixed Spades score calculation that resulted in no loss of points
- Win32 client now supports HTML (IE4+ required)
- Win32 client can now join games by right-clicking on an empty game slot in the game view.
- Fixed major bug in Win32 client that would cause it to crash when sending private messages
- Win32 client can now use /msg to send private messages
