Programming with Google Android and Eclipse
Android is an operating system based on Linux with a Java programming interface. It provides tools, e.g. a compiler, debugger and a device emulator as well as its own Java Virtual machine (Dalvik).
Android is created by the Open Handset Alliance which is lead by Google.
Android uses a special Java virtual machine (Dalvik) which is based on the Apache Harmony Java implementation. Dalvik uses a special Bytecode so that you have to use the Android compiler to create this special byte-code.
Android supports 2-D and 3-D graphics using the OpenGL libraries and supports data storage in a SQLLite database.
For development Google provides the Android Development Tools (ADT) for Eclipse to develop Android applications.

GPU programming using .NET languages
Our project, which is called IL Shader, allows writing vertex and fragment programs using general purpose programming languages on .NET platform. Our project is based on three-stage translation. First, MSIL bytecode is translated to assembly language of abstract machine with vector registers. Then we perform some optimization and finally translate abstract machine code to one of assembly language shaders (currently DirectX pixel and vertex shaders). We provide infrastructure that allows using .NET classes as shaders. This project is supported by Microsoft Research grant.

Graphical Interfaces for C#
A new environment called .NET was recently introduced to wide public. However, this environment does not contain libraries for advanced graphical output. Therefore it is necessary to make such libraries available to .NET. This paper describes our implementation of graphical library interfaces. The implementation allows cooperation of graphical interfaces with .NET. We have dealt with interfaces of libraries such as OpenGL, DirectX, and Visualization Toolkit (also known as VTK). A short description of libraries is included as well as a short introduction to .NET environment. We also present results, advantages, and disadvantages of our implementation. This paper contains neither comparison of the graphical libraries nor comparison of .NET environment and other environments.
