This article compares two styles of building data structures and data structure libraries in C++: (a) Intrusive data structures formed by pointers stored inside the application objects, (b) Containers where auxiliary objects form the required data structure, and only point to the application objects without adding any pointers or other data to them.

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.

Parallel prefix networks are used in priority encoders, and to compute carries in fast adders. A typical microprocessor contains many such networks, and often they are hot- spots. Although parallel prefix (or scan) has been much studied, surprisingly many questions remain unanswered. As geometries shrink, it is not at all clear how to make low power prefix networks with the desired timing properties. Here, I develop a method of writing very highly parameterised parallel prefix network generators in which we specify the combinators used to build the networks and then search for a topology that matches the given delay constraints. This first case study indicates that, in this functional setting, combinators and search fit well together. The resulting prefix networks are both small and shallow, and likely to be useful in low power applications.

This WEPP software consists of an erosion prediction model (WEPP) written in the Fortran programming language, a climate generator program (CLIGEN) also written in the Fortran programming language, and a Windows interface (WEPPWIN) written in the Visual C++ programming language. The interface accesses databases, organizes WEPP and CLIGEN simulations, creates all necessary input files for WEPP and CLIGEN, and executes the Fortran models when necessary. The interface also accesses and processes output information from the Fortran models for display and access by the user.

This is the tale of 101 Damnations. Sadly, it’s no Disney story - in fact it’s more likely to have been pulled from the pages of the Brothers Grimm. Whilst writing the EJB modules for our JGenerator product, we started punting an email back and forth containing all the issues we had with EJB. And there were many. Before we knew it we ended up with 101 howlers. In this article we present an edited version of the email. It isn’t a complete list and there may be some overlapping issues. If there is enough interest we will turn it into a more formal analysis.

Microsoft provides a very simple layer between the web interface (asp.net 2.0) and the database. The object they use to perform this is the SqlDataSource. It works very well in many cases. It’s fast, easy to use and great for demonstration of technology and to show how fast you can program database type applications. It falls apart (IMHO) when the application starts getting larger and requiring more customization. It’s also very hard to maintain because at the end of the day, it puts most of what it does in the aspx page itself.

Why FullText Search is Important?
? Is not it silly question to ask ?
? Natural way for humans to search for information
– Search engines took over catalogs as traffic generators in a web long ago
? Quickly growing amount of information stored
– Personal information, Business information, community information etc.

The .NET platform claims to be a melting pot that allows the integration of different languages in a common framework, sharing a common type system, CTS, and a runtime environment, CLR (Common Language Runtime). Each .NET compiler generates portable MSIL byte-code (MicroSoft Intermediate Language). By assuming compliance to the CTS type system, components inter-operate safely.

The .NET framework is actually well suited for object-oriented languages which have an object model close to the one of C# or Java. Unfortunately, languages with other kinds of object models, type systems or supporting different programming paradigms (such as functional programming .. . ) do not fit in .NET as well as C# does. Writing .NET compilers for them requires much more efforts.
