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.
Keyring for PalmOS lets you securely store secret keys and confidential information on a PalmOS handheld computer. This information might include computer account passwords, credit card numbers, GnuPG or PGP passphrases, SKey one-time-pads, or phone banking keywords. Records are encrypted using the well-trusted DES3 algorithm on a master password. When you need to set a password, Keyring can generate a random password of specified length, optionally including letters, numbers, or symbols.
SameGame2 is a PalmOS version of the highly addictive game SameGame. There are two main objects of SameGame2: remove as many tiles as possible, and remove tiles in the largest possible groups. You get points for each group of tiles you remove, and the larger the group, the higher the score. The code is for the IDE Falch.net, but can easily be built with prc-tools; all that is needed is a makefile.
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.
