Shezhu Resource Sharing System project is an application for scheduling and booking shared resources such as rooms and equipment.
The client only needs a modern Web browser.
It has a user friendly point and click interface, visual filters for making block/repeat bookings, concurrent users and double booking prevention, allows local site customization, and supports configurable academic term/semester blocks.
Main features:
- Portable - client only needs a modern web browser
- Point and Click - almost no typing required
- Intuitive - simple, obvious, consistent and user friendly
- Innovative - visual filters for making block/repeat bookings
- Powerful - concurrent users and double booking prevention
- Configurable - local site customization supported
- Useful - built in support for configurable academic term, semester and session blocks
- Free!
Requirements
In order to run or build the Shezhu Resource Sharing System you need some third-party software available on your machine.
Client
The client needs a modern web browser and the best browsers for this application are Firefox, Mozilla (including the Netscape branded equivalent and Gecko derivatives such as Galeon) and Microsoft Internet Explorer. The newest versions of all these browsers will work best. This application also works with the Konqueror and Opera browsers but these have some issues which may affect functionality. All browsers need JavaScript enabled. Any of these browsers may not work properly (or at all) depending on the operating system they are running under. Text based browsers (such as Lynx) are not supported.
For a comprehensive list of supported client browsers and operating systems refer to this browser compatibility chart from the most recent release of the application.
Server
The server needs recent versions of the Apache web server and the MySQL database server.
The server has only been tested on Redhat9 and FedoraCore3 Linux/i386 platforms although there is no specific reason why it should not work on other Linux platforms and distributions.
Development
Rebuilding this application from source requires a standard Unix development environment with the sh, make, cc, cpp, sed and awk utilities. Also required are RCS, Perl (5.6+) and the ImageMagick program. Also required is RPM to build a distribution. All these programs would probably come as standard in Linux distributions, other platforms may not have all of them by default.
Enhancements:
- This release adds support for Apache2 and multi-site installations, internal restructuring, a better installation tree, and improved access control management.

Coda is an advanced networked filesystem. The project has been developed at CMU since 1987 by the systems group of M. Satyanarayanan. in the SCS department.
Coda is a distributed filesystem with its origin in AFS2. It has many features that are very desirable for network filesystems. Currently, Coda has several features not found elsewhere.
1. disconnected operation for mobile computing
2. is freely available under a liberal license
3. high performance through client side persistent caching
4. server replication
5. security model for authentication, encryption and access control
6. continued operation during partial network failures in server network
7. network bandwith adaptation
8. good scalability
9. well defined semantics of sharing, even in the presence of network failures
Enhancements:
- Coda now works on 64-bit systems.
- The client and server were successfully built and used on a machine with em64t extensions with a 64-bit Linux kernel.
- The new RVM-1.14 and RPC2-2.5 releases also incorporate some essential 64-bit fixes.
- Another welcome change is that venus now tries to keep cached access rights available for users even across system reboots or client restarts, which should improve life for people who frequently shut down or dual boot their machines.

Web Sharing is a small tray applet for sharing files on the web.

KDE Internet share wizard is a Kommander script that can help you share your internet connection over LAN.
Overview:
I was on a LAN and I needed to share my internet connection because we didnt have any router.
I found this to be quite difficult, but after some searching on internet I found a very good explanation for making this work.
Now, Ive made a WindowsXP like internet connection sharing guide for all who wants to share their internet connection easy and fast.
Usage:
copy the tar.gz file contents into /usr/bin and then run:
kdeinternetshare.sh - English
For all those who are unsure how to use the guide, it should be good to stick to the default settings.
This is only a quite simple guide so suggestions and improvments are welcome.
System requirements:

file*HANDLER project is primarily a Perl script which coordinates some free media conversion packages (cited later) with a PostgreSQL back end accessing server to index and serve binary and text files direct from the database. A simple CGI file with embedded AJAX makes calls to this server which is also constantly looking for other alive f*H servers on the Internet.
Since the server caches media into the SQL database on demand, as the network grows, the network improves.
Its gridded directory sharing/browsing/searching with streaming audio/video as well as flat text/doc/pdf/image display for everyone. Its written with a few hooks for tags that would be included in your actual front page so that the UI is discard-able -- anyone can quickly rewrite a whole new [GT]UI without having to worry about the syntax of the newest version of dojo.licio.r or whatever.
If you wanted to ignore the JS/HTML/CSS hooks then you can easily use the system to make direct requests that just return lists formatted as HTML table-bodies. In other words, the markup IS the markup.
As such, Ive whipped up a Dojo 0.2 Widget that coordinates the serving backend with a UI so anyone can embed f*H functionality anywhere, or easily customize a provided default page.
A file*HANDLER server is really a few constituent parts Ive tied up for you (top down):
- A local web page providing the UI(served by an HTTP server of your choice) that is generated by a cgi script with embedded AJAX.
- A secondary portion of the same CGI script, acting as middle-ware, which communicates, via AJAX, with the local front page to reconcile asynchronous JavaScript requests with the file*HANDLER sub-network back-end.
- An always-on network server written in PERL that serves to the front and end communicates laterally with everyone elses file*HANDLER back-end PERL server additionally, it manages indexing of content directories you choose to serve.
- A PostgreSQL database that is accessed only via internal PERL routines called from your front page.
So for example, a remote user comes to your site. First, not only can they browse and search your files, but they can also browse and search the files of anyone else hosting a file*HANDLER server that your local server knows about. (file*HANDLER identifies other servers on the network automatically). The user can now read/view/listen/watch by stream any content they find from whomevers server. Theres no download, so theres so actual sharing, just direct streaming to the users browser.
