Free 32 software for mac

RUnit is a pop-up terminal-like application that runs any command (Shell script, Unix binary, etc...) any time you want by simply pressing a key combo and then typing the alias you defined to perform the command.

Completly freeware for non-commrcial use.

MacXM is a Java/Cocoa application for controlling the receiver. It is an open source application intended for use with a Mac via a USB port.
Features:
- Shares the same basic layout as the stock XM PCR software, but does so without reinventing the UI. MacXM looks and works just like any other Mac OS X application.
- Built-in help, just a keystroke (command-?) away.
- Integration with the iTunes music store.
- Integration with Google.
- Integration with XM radios own web site.
- If you activate online, you can copy your radio ID to the clipboard rather than type it in.
- "Smart" mute lets you mute the audio until the current song (or ad) ends.
- Rate songs as you listen to them. The ratings will eventually go directly into XM to provide feedback to the DJs
- AppleScript support lets you automate tasks - make your own XM radio alarm clock
- Scan functions to let you surf through channels
- Search functions alert you when your favorite artists and/or songs are played. Fuzzy logic is used to make up for misspelled or truncated data
- The main channel grid is keyboard navagable
- A Status Icon can be added to the menu bar (to the left of the clock). The menu that hangs off the icon can be used to do just about everything you can do in the compact view, meaning you can use MacXM without even having the window visible

Zile is a small Emacs clone. Zile is a customizable, self-documenting real-time open-source display editor. Zile was written to be as similar as possible to Emacs; every Emacs user should feel at home.
Main features:
Small.
- It is very useful for small footprint installations (like on floppy disk) or quick editing sessions. A typical binary is about 100Kb.
8-bit clean.
- Zile can operate with binary files.
Looks like Emacs.
- Most Zile key sequences and function names are identical to Emacs ones.
Multi buffer editing with multi level undo.
- The number of files and undo operations that Zile can handle is limited only by memory.
Multi window.
- Zile can display multiple windows on the screen.
Killing, yanking and registers.
- The standard killing, yanking and register features of Emacs are available under Zile.
Minibuffer completion.
- Zile is able to complete filenames and commands in the minibuffer.
Auto fill (word wrap).
- Zile automatically breaks the lines when they become too wide (if the Auto Fill Mode is enabled).

Asymptote is a powerful descriptive vector graphics language that provides a natural coordinate-based framework for technical drawing. Labels and equations are typeset with LaTeX, for high-quality PostScript output.
A major advantage of Asymptote over other graphics packages is that it is a programming language, nor just a graphics program.
Main features:
- provides a portable standard for typesetting mathematical figures, just as TeX/LaTeX has become the standard for typesetting equations.
- inspired by MetaPost, with a much cleaner, powerful C++-like programming syntax and floating-point numerics;
- runs on all major platforms (UNIX, MacOS, Microsoft Windows);
- mathematically oriented (e.g. rotation of vectors by complex multiplication);
- LaTeX typesetting of labels (for document consistency);
- uses simplex method and deferred drawing to solve overall size constraint issues between fixed-sized objects (labels and arrowheads) and objects that should scale with figure size;
- fully generalizes MetaPost path construction algorithms to three dimensions;
- compiles commands into virtual machine code for speed without sacrificing portability;
- high-level graphics commands are implemented in the Asymptote language itself, allowing them to be easily tailored to specific applications.
