• Freely available software I've written, all as open source under the Artistic License:
  • The Humble Narrator is a Facade, or simplifying overlay, for text-to-speech synthesis in Java programs. It is not a speech synthesizer. It only overlays another speech synthesizer, providing a uniform and easy-to-use API. Includes ready-to-use implementations for Mac OS X 10.1 or higher, on PowerPC or Intel processors.
  • The Suite/P Toolkit for Java is a simple extensible suite of Posix-style capabilities. The typical capabilities allow Java programs to work with user ID, group ID, process ID, hard & soft resource limits, environment variables, and inter-process signals. Includes a ready-to-use Mac OS X implementation based on JNI.
  • The Authorization Toolkit for Java is a simple facade over an arbitrary authorization and authentication service. The API allows a Java program to exercise special privileges, such as the ability to run another program as root. Includes a ready-to-use Mac OS X implementation based on Authorization Services.
  • The MacBinary Toolkit 2 for Java converts to and from MacBinary, and provides generalized Mac OS access to resource-forks and file-catalog info. More than jast a MacBinary class library, it's a powerful and flexible I/O library that knows about resource-forks, metadata, and aliases, and can be extended to work with protocols like netatalk or NTFS.
  • The WeatherEase Toolkit for Java reads web-based weather data and decodes it into Java objects like Sky, Wind, Temperature, and WeatherReport, which your program uses. You can extend the toolkit to read other data sources.
  • The Gadget-Kit for Java, including X-10 device control through a CP290 serial-port interface, and daily or weekly scheduled control.

• Other software including tests, code snippets, bug fixes, etc. A few highlights are:
  • Imager Trials is a simple flexible public-domain framework for running speed trials of different Graphics or Graphics2D operations on different BufferedImage types.
  • Sun's Java Image Management (JIMI) library has a couple of bugs writing PICT files. Easily remedied, I'm providing Wyatt Tellis's fixed version of the PICTWriter source.

• Technical how-to articles on various subjects, often related to Java and Mac OS:
  • 2004 Mar 16 -- More Open Files for Java Apps on Mac OS X tells how to raise the limit on open files for double-clickable bundled Java apps. Includes directions for modifying an existing Java app, and for building one directly in ProjectBuilder.
