ClanLib is a cross-platform game SDK currently supporting Windows and Linux. It provides easy-to-use interfaces for 2D graphics, input, sound, resources, networking, GUI, OpenGL, and more. The goal is to provide a game SDK that does all the dirty work that all modern games need to implement anyway, thus making the game developer concentrate on the gameplay instead of reinventing the wheel over and over again.
The SDL_gfx library offers several components: Graphic Primitives, Rotozoomer, Framerate control, and MMX image filters. The Primitives component provides basic drawing routines: pixels, hlines, vlines, lines, aa-lines, thick-lines, rectangles, rounded-rectangles, boxes, rounded boxes, circles, aa-circles, ellipses, trigons, polygons, textured-polygons, Bezier curves, and an 8x8 pixmap font for drawing onto any SDL Surface. Full alpha blending, hardware surface locking, and all surface depths are supported. The Rotozoomer can use interpolation for high quality output.
PhysicsFS is a library to provide abstract access to various archives. The programmer defines a "write directory" on the physical filesystem. No file writing done through the PhysicsFS API can leave that write directory, for security. For file reading, the programmer lists directories and archives that form a "search path". Once the search path is defined, it becomes a single, transparent, hierarchical filesystem. This makes for easy access to ZIP files in the same way as you access a file directly on the disk, and it makes it easy to ship a new archive that will override a previous archive on a per-file basis. Symbolic links can be disabled, for added safety. Finally, PhysicsFS gives you a platform- abstracted means to determine if CD-ROMs are available, the user's home directory, where in the real filesystem your program is running, etc.
Fing is a command line tool for network and service discovery. It provides you a complete view of any network in a very short time. Its smart discovery automatically detects the network type and uses the best technique to scan it. The best results are achieved on Ethernet networks (including Wireless ones), where Fing is able to detect all network hosts, firewalled ones included. The service discovery feature quickly detects active TCP services on a target host or network. Fing is based on Look@LAN.
RTSPdump is a tool for downloading a multimedia stream from a Windows Media server (WMServer). It accepts rtsp:// and mms:// URLs. It supports both UDP and TCP traffic. The stream can be saved into a WMV file for archiving or timeshifting purposes or passed through stdout to another program for processing or immediate viewing. It has also limited support for other brands of servers that also provide RTSP streaming.
Octaspire Crates! is a scriptable, skinnable, extensible, and relocatable 3D action puzzle game. All the missions, game entities (or crates), game states, and configuration of the game engine are implemented as plain text Lua-scripts. So, if you know Lua, you can write new game entities, game states, missions, and levels with any text editor, without any special development tools. New skins can be created with any image editor that can save .png images, dropped into a new subdirectory under the resources/textures directory, and changed in the configuration file config.lua. Crates has also its own (simple) implementations for all the different container classes it needs (like vector, string, and so on) to keep the external dependencies fewer.
