Free thin layer software for linux

iFLUX is a PHP Framework project based on Model-View-Controller MVC Desing Patern.

It uses AdoDB and other classes to implement the Model Layer, Smarty to implement the View Layer, and Fuse Box to do the Controller.

ENets purpose is to provide a relatively thin, simple and robust network communication layer on top of UDP (User Datagram Protocol). ENets primary feature it provides is optional reliable, in-order delivery of packets.
ENet is NOT intended to be a general purpose high level networking library that handles authentication, lobbying, server discovery, compression, encryption and other high level, often application level or dependent tasks.
Main features:
ENet evolved specifically as a UDP networking layer for the multiplayer first person shooter Cube.
Cube necessitated low latency communcation with data sent out very frequently, so TCP was an unsuitable choice due to its high latency and stream orientation.
UDP, however, lacks many sometimes necessary features from TCP such as reliability, sequencing, unrestricted packet sizes, and connection management. So UDP by itself was not suitable as a network protocol either.
No suitable freely available networking libraries existed at the time of ENets creation to fill this niche.
UDP and TCP could have been used together in Cube to benefit somewhat from both of their features, however, the resulting combinations of protocols still leaves much to be desired.
TCP lacks multiple streams of communication without resorting to opening many sockets and complicates delineation of packets due to its buffering behavior.
UDP lacks sequencing, connection management, management of bandwidth resources, and imposes limitations on the size of packets.
A significant investment is required to integrate these two protocols, and the end result is worse off in features and performance than the uniform protocol presented by ENet.
ENet thus attempts to address these issues and provide a single, uniform protocol layered over UDP to the developer with the best features of UDP and TCP as well as some useful features neither provide, with a much cleaner integration than any resulting from a mixture of UDP and TCP.
Enhancements:
- Lower bandwidth usage, stability/crash fixes, more flexible packet allocation, optional CRC32 checksums, and various API tweaks.

Common Media Input Layer (CMIL) is an C++ OO framework designed to improve the state of cross-platform input handling in games and other similar applications.
CMIL was created out of the belief that the methods used in most media APIs perform input handling in a confusing, difficult, inflexible fashion. CMILs goal is to address this issue by establishing a flexible, easy to use, human readible, OO abstraction layer. This layer specifically allows for media and input device abstraction.
Main features:
- easiliy build complex input sequences, including timed inputs, which do not impose restrictive notions of what is and isnt a moderator on the user
- custom input device configurations, IE: Users can swap input device configurations on the fly and create their own representation of a custom device using the framework facilities

libbehate is a library with implementation of BHT communication protocol.

This protocol is used in communication with Toyota Denso data collection terminals. Library itself uses librs232 for link layer.

Library is released under the term of LGPL license.

NoMachine NX Desktop Server is a cost-effective solution that enables any business to deploy centralized applications to thin clients, mobile and home workers, over any network connection, with astonishing speed and ease of use.
NX uses the power of the X-Window system to bring the network transparency of the Unix world to any operating system, including Windows and Mac OS/X. Additionally NX bridges the standard file and print services of the client, with the Unix file and print services of the server, so that, wherever you are, you can see the same applications and the same network resources.
Besides the native X-Window protocol, NX is able to translate, encrypt and compress industry standard protocols like the RDP protocol, used by Microsoft and Citrix, and the VNC protocol, used by a number of freely available tools, giving secure and fast access to the complete set of facilities made available inside a corporate network. The power of network computing has never been more affordable!
Main features:
- Deploys X11, RDP and VNC desktops securely over the Internet
- Provides unmatched performance, thanks to exclusive compression and aggressive caching
- Connects to XDMCP servers, Windows Terminal Services and Citrix MetaFrame servers on the backend, using the same client
- Seamlessly integrates single X11 applications with the native client desktop
- Lets users leave their applications running while disconnected and resume from any client on the network
- Lets applications access any file system on the client as if it were on the server
- Lets users cut and paste between local and remote applications
- Prints from the server to printers installed on the client
- Plays sound and multimedia produced by the remote application
- Integrates with your authentication infrastructure and directory service
- Supports industry standard SSL encryption and Transport Layer Security
- Fully integrates with SSH, avoiding the need for a further network access port
- Provides seamless integration with Web portals and corporate Intranets with one-click access to any application.
Enhancements:
- The new packages fix a number of problems such as the server Debian package not being fully Debian compliant, the NX server leaving a session in status Connecting when trying to suspend it, and the server being unable to find the xauth command on Solaris platforms.

Thinstation is a thin client Linux distribution that makes a PC a full-featured thin client supporting all major connectivity protocols: Citrix ICA, No Machine NX, MS Windows terminal
services (RDP), Tarantella, X, telnet, tn5250, VMS term and SSH.

No special configuration of the application servers is needed to use Thinstation!

Thinstation can be booted from network (e.g. diskless) using Etherboot/PXE or from a local floppy/CD/HD/flash-disk. The thin client configuration can be centralized to simplify management.

Thinstation supports client-side storage (floppy/HD/CD/USB) and printers (LPT/USB). Prebuilt images and a Live CD are available too!

Mozilla Firefox and lighter browsers are supported as client-side browsers.

Phpfw is a framework for PHP that provides a base on which various database backend applications can be built. Phpfw project allows for easy creation of CRUD applications - apps where most of the code is focussed on Create Read Update Delete operations on the database. It uses MVC-ish patterns to allow for simpler and cleaner organization of code.
Phpfw leverages popular PHP libraries so as to avoid reinventing the wheel. For example, the database abstraction layer is a thin wrapper that supports ADOdb and ADOdb Lite. Hence, Phpfw is able to support multiple databases thanks to these excellent libraries.
Phpfw requires minimal configuration. All the database information is directly obtained from the database itself. The configuration file is a simple .ini file and is adequately commented to explain the different elements.
Phpfw comes built in with an elementary templating class to generate HTML output. Further it also supports templating frameworks like Smarty and PHPTAL. The combination of these templating facilities provides adequate power to generate simple to complex output.
Phpfw is the result of several PHP projects I undertook over the years. It grew inside active projects and has finally taken a life of its own. It has been written from scratch based on all the code that was written over the years with a focus on simplifying the process of creating new applications with minimal effort. I hope this work proves useful to those of you who would like to put together applications quickly and easily.
Enhancements:
- Several enhancements were made in the core API such as AJAX support, database schema auto-load and optional database usage.
- New modules include Config, MailServer, and PelWrap.
- Enhancements were made to existing modules to allow login from file.
