goinedit is a text editor and integrated development environment for developing applications in a range of programming languages. It features an integrated shell terminal, buttons for compiling, executing, and debugging, and support for scripts that can provide configurations for new languages. It includes support for PIC microcontroller programming, using SDCC as the default compiler, and pk2cmd to flash EEPROMs.
The GUIShell project is a collection of utilities facilitating the use of the GTK+ toolkit in shell scripts through the gtkshell utility. The ACE configuration environment provides sample scripts utilizing gtkshell for desktop utilities. rootcat provides the ability to display messages to the root window using Xft, allowing one to write status display scripts.
Reindeer is a C library for the rendering of virtual scenes, mainly in three dimensions. The library dynamically loads backend modules to do the rendering. Currently there is only a backend for OpenGL, but ideas for future backends are a raytracer and perhaps Direct3D. Any number of rendering contexts can live at the same time. Contexts are tied to a backend, and backends are automatically loaded and unloaded on demand. Resources are defined globally and can be used by any number of contexts at the same time, even in different backends. The main goal is to make it easier for developers to write applications that have many rendering contexts with shared resources and automatic state management. Another advantage is that the user can choose in which way a scene should be rendered without recompiling the application. For example, a scene could be rendered with a rasterizer like OpenGL at one point, and with a raytracer at another. Reindeer can also be used to get portable graphics output. Reindeer is not a scene-graph library or a game engine, but it can be used to implement them. It's still up to the application to create and manage the native contexts that the Reindeer backends can work on. For example, an application would still need to use GLX or equivalent to be able to use the OpenGL backend. The Reindeer project also provides a package called GTK-Reindeer that makes this easier for developers of GTK+ applications.
Jenny is a packet generator, injector, editor, and browser for network and penetration testing. You can use Jenny to produce and manipulate network traffic (such as packets and frames), to browse pcap files and edit them, and to inject or save your changes as a new pcap file. It works only in GUI mode, and must be run as root.
Déjà Dup is a simple backup tool. It hides the complexity of doing backups the 'right way' (encrypted, off-site, and regularly) and uses duplicity as the backend. It features upport for local or remote backup locations, including Amazon S3. It securely encrypts and compresses your data. It incrementally backs up, letting you restore from any particular backup. It schedules regular backups, and integrates well into your GNOME desktop.
