ChucK re-factors the idea of a computer music language into three orthogonal basis components: unit generator connections that are data-flow only, globally consistent ”first-class” time control, and sample-synchronous concurrency. The syntax, semantic, and usage have been discussed in previous works. The focus and contributions of this paper are (1) to examine the philosophies and decisions in the language design (2) to describe ChucK’s implementation and runtime model, and (3) to outline potential applications enabled by this framework. We present an experiment in designing a computer music language ”from scratch” and show how things work. We hope these ideas may provides an interesting reference for future computer music systems.

The CPC GPS ushers in the next generation of computer automated telescopes. The CPC series uses GPS (Global Positioning System) technology to take the guesswork and effort out of aligning and finding celestial objects in the sky. Simple and easy to use, the CPC with its on-board GPS, is up and running after locating just three celestial objects. It’s so advanced that once you turn it on, the integrated GPS automatically pinpoints your exact coordinates. No need to enter the date, time, longitude and latitude or even know the name of a single star in the sky. If you are new to astronomy, you may wish to start off by using the CPC’s built-in Sky Tour feature, which commands the CPC to find the most interesting objects in the sky and automatically slews to each one. Or if you are more experienced, you will appreciate the comprehensive database of over 40,000 objects, including customized lists of all the best deep-sky objects, planets and bright double stars. No matter at what level you are starting out, the CPC will unfold for you and your friends all the wonders of the Universe.

Google Earth™ is Google’s satellite imagery-based mapping product that combines global coverage of imagery with new navigational features including integrated Google search capabilities. It is based on technology from Keyhole, a company acquired by Google in October 2004. Google Earth is a broadband mapping tool that enables users to fly from space to street level views to find geographic information, and to explore places around the world.

How does Google decide which web sites are important? It uses an ingenious algorithm that exploits the structure of the web and is resistant to hacking. Here, we describe this PageRank algorithm, illustrate it by example, and show how it can be interpreted as a Jacobi iteration and a teleporting random walk. We also ask the algorithm to rank the undergraduate mathematics classes offered at the University of Strathclyde. PageRank draws upon ideas from linear algebra, graph theory and stochastic processes, and it throws up research-level challenges in scientific computing. It thus forms an exciting and modern application area that could brighten up many a mathematics class syllabus.

Google Earth is a popular and widely used geographical browser. It is a standalone application that enables spatial data from a variety of sources to be displayed, explored and visually compared. Google Earth has the following important characteristics:
• Free
• Easy-to-use and intuitive user interface. Data are displayed on an interactive globe that can be rotated and zoomed to visually explore data in different regions of the world and at different spatial resolutions.

The Query API described in the first part of this document was introduced with Google Desktop 3. We cover how to use it with both native plug-ins and script-based plug-ins, and assume that you are familiar with the general principles of how to write Desktop plug-ins. The latter part of this document describes methods for issuing Desktop search queries using HTTP and XML. This XML-based API is supported by both the Windows and Mac OS X versions of Google Desktop. Mac OS X support was added in Google Desktop Mac 1.0.3.
