XCircuit is a UNIX/X11 program for drawing publishable-quality electrical circuit schematic diagrams and related figures, and producing circuit netlists through schematic capture. XCircuit regards circuits as inherently hierarchical, and writes both hierarchical PostScript output and hierarchical SPICE netlists. Circuit components are saved in and retrieved from libraries which are fully editable. XCircuit does not separate artistic expression from circuit drawing; it maintains flexiblity in style without compromising the power of schematic capture.
GLE (Graphics Layout Engine) is a graphics scripting language designed for creating publication quality figures (e.g., a chart, plot, graph, or diagram). GLE supports various chart types (including function plot, histogram, bar chart, scatter plot, contour plot, color map, and surface plot) through a simple but flexible set of graphing commands. More complex output can be created by relying on GLE's scripting language, which is full featured with subroutines, variables, and logic control. GLE relies on LaTeX for text output and supports mathematical formulae in graphs and figures.
Oberon2 is a simple and safe object-oriented language created by N.Wirth, the author of Pascal and Modula2. It is statically strongly typed and has garbage collection. Most of good ideas incorporated in design of Java were in Oberon2 long before. OOC is an open source project to produce a family of optimizing Oberon2 compilers. The compiler with an ANSI C back-end, oo2c, is quite mature, and provides a complete and convenient Oberon2 development environment. It comes with a rather comprehensive standard library, Code Navigator, and an Emacs mode. It is easy to call C functions and libraries from Oberon2.
Mad Bomber is a clone of Activision's 1981 Atari 2600 classic, "Kaboom!" The Mad Bomber rushes back and forth at the top of the screen and drops bombs which you must catch with your bucket. If one drops, you lose a bucket and go back one level. One or two players can play, using keyboard or mouse. There is also a "versus" mode where player two controls the Mad Bomber.
Slash'EM (Super Lotsa Added Stuff Hack -- Extended Magic) is a variant of the hugely popular roguelike game NetHack. It adds more monsters, more objects, more dungeon levels, more roles, and more races, shopkeeper services, and techniques for you to use, and invisible objects and gypsies for those who feel lucky. It also comes with a GTK windowing interface and higher resolution tile sets as options.
spim is a self-contained software simulator for running R2000/R3000 assembly language programs. It reads and can immediately execute files containing assembly language code. spim also provides a debugger and simple set of operating system services. spim provides both a simple, textual interface and a fancier, graphical interface. The package includes complete source code and documentation.
