Core Plot is a plotting framework for Mac OS X and iPhone OS. It provides 2D visualization of data, and is tightly integrated with Apple technologies like Core Animation, Core Data, and Cocoa Bindings.

OpenLAPI is most commonly used to access Bluetooth GPS devices from mobile devices, whilst retaining a high level of source code compatibility with JSR-179. OpenLAPI also has a range of backends for emulating location in development environments, making it a popular tool for J2ME developers.

The emulator mode supports the following back-ends for determining location:-

• Access of hardware GPS device over bluetooth (if available)
• Emulate a moving device from an NMEA log file (recorder application provided).
• Emulate a moving device from a predefined trail in a Google Earth file KML.
• Emulate a moving device by picking random entries from a persistent store

And the software may be shipped as part of a MIDlet (Java application) to provide location awareness.

Rhomobile’s open source mobile application framework Rhodes lets you quickly build native mobile applications for all smartphone operating systems: iPhone, BlackBerry, Windows Mobile, Symbian and Android. Mobilizing with Rhomobile consists of creating a RhoSync source adapter, generating an application with Rhogen, editing your HTML templates and Ruby controller actions and building the resulting application in your mobile development environment of choice. These are true native device applications (not mobile web apps) which work with synchronized local data and take advantage of device capabilities such as GPS, PIM contacts and camera.

Mochalua is a Java ME port of the Lua runtime and API.

Quotes from lua-users.org:

We were aware of Kahlua but it was incomplete when we started the Mochalua project (and may still be). We were also aware that there was another project locked within the bowels of a short-sighted company. So we put our money toward hiring a company, Nikitova, to work with us to do a conversion from scratch.

Mochalua is a port of the Lua runtime and API only, not the compiler. The API functions have kept their original names and signatures from the C implementation with only minor variations to account for language differences. It has been able to pass the Lua test vectors. We have also put it through its paces for our own projects. At this time, it should be a pretty stable codebase for you to use.
