Free to enhance software for linux

Gyach Enhanced (Gyach-E) and pY! Voice Chat. Gyach Enhanced is currently the most feature-rich Yahoo! client for Linux operating systems.

It is an unofficial fork of the original Gyach, and supports almost all of the features you would expect to find on the official Windows Yahoo! client: Voice chat, webcams, faders, nicknames, audibles, avatars, display images, and more.

Yet, it remains very light-weight and memory-friendly. Gyach Enhanced, pY! Voice Chat, and the Gyach-E Webcam Utilities all use Gtk-2 for their user interfaces (Gtk-2 2.0.6 or better required).

Gyach Enhanced is intended to be a deliberate departure from the growing trend of multi-protocol/multi-platform messaging and chat clients which often suffer from half-baked or non-existent support for major features such as voice, webcams, privacy, security, and spam control, and generally offer slower adoption of new protocol features that Windows users have access to almost immediately with each new Y! Messenger release. Gyach Enhanced is never intended to be a multi-protocol application (i.e., not intended for connecting to MSN, AIM, etc.) as I would rather use a client that handles one messaging system and handles it well, than a client that handles only the basics on several systems.

Gyach-E is about PROGRESS: Being among the first, not the last, to implement support for new features. Lately, Gyach Enhanced has been adopting new features at an alarming rate, as the development has not been bogged down with a need to rewrite/recompile code for Windows and other operating systems or a need to delay the addition of new features for fear of its affects on other protocols plugins. In other words: New features are added quickly because I do not have to worry if something will work on Windows or if the new addition will break MSN support...Gyach Enhanced just worries about Yahoo! on Linux: Thats it. "One protocol, one OS...done well.". Gyach Enhanced is also the first Yahoo application for Linux with support for the vast majority of the new features added to the Windows Y! Messenger 6: Display Images in the PM window, Avatars, Audibles, and Stealth Settings.

While other applications prefer to focus on things such as themeable smileys...Gyach Enhanced is focused on USEFUL features such as webcam support, voice chat, controlling spam (about 75-95% effective), and doing the best it can to prevent you from being booted, bombed, flooded, and stalked. Gyach-E is known to survive tons of different boot codes and is constantly being patched to defend against new ones as I find out about them. For example, when support for Audibles was added to Gyach-E, I also anticipated that people would eventually start using Audibles to flood people and send Audible spam, so I also implemented measures to help defend against these types of abuse.

This is part of the concept behind Gyach-E: Allow the user to enjoy the latest features while containing and minimizing any damage that can be caused by people abusing the new features. The program responds intelligently to boot attacks by temporarily shutting down sound events and dialog boxes to avoid X and sound card-related crashes, controlling the flow of incoming network packets, minimizing CPU usage during an attack, auto-ignoring users as necessary, monitoring and logging suspcious events, and sometimes, even booting the bot/person thats trying to boot you.

Together with pY! Voice Chat, the Gyach-E Webcam utilities, and a few light-weight plugins (including encryption support), Gyach Enhanced is the most advanced, feature-rich Linux client for Yahoo! thus far. It is the first (and, to my knowledge, the ONLY) Linux Y! client that supports both voice chat and webcams (sending and receiving.)

Adaptive Contrast Enhancement is a GIMP plugin which can enhance the contrast of images.
The basic "Stretch Contrast" operation takes in the whole image at once, and if there is a white pixel anywhere in the image and a black pixel anywhere in the image, it figures the contrast is already as good as can be. But Adaptive Contrast Enhancement works to increase the contrast locally, and brings out details that most wide-sweeping contrast-enhancements pass over.
Enhancements:
- This is just another development-libgimp-compatibility-thing.
- There is more interesting work going on for the upcoming 0.7, but its not quite ready yet.

autopackage allows developers to produce "install anywhere" packages for 3rd party Linux software. The resulting packages support both graphical and terminal frontends, support dependency checking and resolution, and use deep desktop integration.
Additionally, tools to enhance the packaged software such as binreloc and relaytool are provided. By providing an autopackage, developers can ensure their users always have an easy way of installing the latest release of their software.
autopackage is stable, tested software that has been deployed by high profile projects. It has a strong commitment to backwards compatibility: your packages will continue to install as we add new features, although you may need to recompile them to get the new functionality.
Version 1.0 can build, install, verify and uninstall fairly complex packages (mplayer, gaim, inkscape etc), and promises backwards compatibility from this point forward.
Autopackage can resolve dependencies either from local files or from remote servers. It currently has simple support for package updates. It does not support integration with the native package manager although these features are planned for after the 1.0 release.
Main features:
- Build packages that will install on many different distros
- Multiple front ends: best is automatically chosen so GUI users get a graphical front end, and command line users get a text based interface
- Multiple language support (both in tools and for your own packages)
- Automatically verifies and resolves dependencies no matter how the software was installed. This means you dont have to use autopackage for all your software, or even any of it, for packages to succesfully install.
Enhancements:
- KDE not finding the hidden .desktop that associates x-autopackage -> autopackage-launcher-gtk on Fedora Core 3/KDE 3.3 - change Category to Categories in autopackage-launcher-gtk.desktop
- Package did not install with apkg-installer after executing .package with -d function stripDupedItems was updated to pass unit test autopackage RPM requires autopackage-gtk RPM function safeSed mishandled language detection for in-place editing
- Two desktop files were being generated - not correctly detecting if the Gnome version installed supports XDG .desktop locations
- Working directories were not being deleted makepackage checks for sealed packages not being included

Enhanced TightVNC Viewer package is a project to add some patches to the long neglected Unix TightVNC Viewer. Enhanced TightVNC Viewer also adds a GUI for Windows and Unix that automatically starts up a STUNNEL SSL tunnel for SSL connections to x11vnc (or any other VNC Server also running an SSL tunnel, such as STUNNEL, at their end), and then launches the TightVNC Viewer. The program can also be used set up SSH tunnelled connections instead.
Main features:
- SSL support for connections using the co-bundled stunnel program.
- Automatic SSH connections from the GUI (system ssh is used on Unix; co-bundled plink is used on Windows)
- rfbNewFBSize VNC support on Unix (screen resizing)
- cursor alphablending with x11vnc at 32bpp (-alpha option)
- xgrabserver support for fullscreen mode, for old window managers (-grab option).
The Viewer SSL support is done via a wrapper script (bin/ssl_tightvncviewer) that starts up the STUNNEL tunnel first and then starts the TightVNC viewer pointed at that tunnel. The bin/ssl_vnc_gui program is a GUI front-end to that script. See this FAQ for more details on SSL tunnelling.
The rfbNewFBSize support allows the enhanced TightVNC Unix viewer to resize when the server does (e.g. "x11vnc -R scale=3/4" remote control command).
Enhancements:
- The Unix VNC Viewer now supports UltraVNC file transfer via an auxiliary Java program.
