The ATLAS (Automatically Tuned Linear Algebra Software) project is an ongoing research effort focusing on applying empirical techniques in order to provide portable performance. It provides C and Fortran77 interfaces to a portably efficient BLAS implementation, as well as a few routines from LAPACK.
Ostiary allows a client to run scripts on a server in a secure, authenticated manner, using an extremely simple protocol that is immune to buffer-overflow attacks. It is useful as a limited ssh/lsh replacement, or to selectively enable full remote shell access on a temporary basis. Clients for Windows, Unix, iOS, Android, and Palm are available.
The pilot-link suite of tools contains a robust library and a series of conduits for moving information between your desktop or workstation and your Palm handheld device, such as those made by Palm, Sony, Handspring, Handera, and others. It also includes language bindings for languages such as Perl, Python, and Java.
VeloAce is a bike computer for Palm OS. It provides data logging, trip data estimation, a trainer, a graphical speedometer, and display of current, average, and maximum velocity, acceleration, trip time, and distances. Base units can be kilometers or miles. The wheel sensor can be connected over RS232 or even IrDA.
SuperWaba is a VM for PDAs. Because of the way it was written, you can use Java to develop programs for it. It supports exceptions, threads, many user interface controls, double and long 64-bit types, grayscale, color, 3D controls, and JNI and Java libraries, among other features. The project has been superseded and replaced with TotalCross.
Weasel Reader is an e-text reader for Palm OS. It is geared towards reading Project Gutenberg e-texts, but will work on any ASCII file. It uses zlib for compression, resulting in good file sizes, an important consideration for Palms. Weasel reads both zTXT (its own format) and PalmDoc files. It includes features such as bookmarks, annotations, categorization, searching, beaming, VFS access, and many display options. Also included is makeztxt, a command line program to generate zTXT databases. makeztxt supports regular expressions to automatically generate a list of bookmarks. Java and Perl/PHP versions of makeztxt are also available.
