This article explains a solution on how to increase the performance of your ASP pages that rely on gathering data through several different Recordsets. Specially, using a nifty feature of the ADO Recordset object, Multiple Recordsets, you can store multiple SQL query results in one Recordset object, requiring fewer communications with the database.

This article shows a simple way to upload files from client to server using VBS, IE and ADODB as multipart/form-data document. Full source code included.

While it's common to hear that synchronized method calls can be 50 times as expensive as unsynchronized method calls, these numbers can actually be quite misleading. With each successive JVM version, overall performance has improved, and the cost of uncontended synchronization has been reduced, making the issue of uncontended synchronization overhead less significant. Contended synchronization, however, is quite expensive. Moreover, a high degree of contention is disastrous for scalability -- an application that had a high degree of contended synchronization will exhibit markedly worse performance as the load increases. This article explores several techniques for reducing contention, and hence improving scalability, in your programs.

Project Jxta is a community-run attempt to build a utility application substrate for peer-to-peer applications. The initial reference implementation of Jxta includes a command-line shell that allows experimentation with the core Jxta platform without programming. This article takes us through a hands-on tour of the <a href="http://www-106.ibm.com/developerworks/java/library/j-p2pint2?open&l=766,t=grj,p=Jxta2">Jxta shell</a>. You'll explore its command set and extend its capability by writing your own custom commands using the Java programming language.

This article presents a nice little chat system that uses Microsoft's XMLHTTP Object to transfer the messages and user list. It features public as well as private modes, and is currently configured so that the browser requests the current users list from the server every 5 seconds. This article assumes that you are familiar with ASP, XML and HTML.

Why invent the wheel every time you develop an application in Java? Writing a J2EE web application is complicated enough; you would not write a linked list module in C++ every time you started a new project. You would rather use another person's implementation. The same reuse-idea surely applies to server-side web development. This article looks at the best practices of using one popular web application toolkit, Expresso Framework. The idea of using custom tags, JSP, and the MVC paradigm are suitable for such frameworks. It will illustrate the best of practice through an on-line stock trading program example.

Based on the Darwinian principle of survival of the fittest, genetic programming uses mutation and replication to produce algorithms for creating ever-improving computer programs. In this column, you'll get to know the genetic algorithm in simple terms. This article provides Perl implementations for some specific tasks, which you can adapt for generic use. To demonstrate the genetic algorithm, the author breeds numbers for fitness to a formula, and letters to form English words.

In multithreaded code, it is often common to use a single, master thread that drives the actions the other threads take. This master thread may send messages, often by placing them on a queue, that are then processed by the other threads. But if the master thread throws an exception, the remaining threads may continue to run, awaiting more input to the queue, causing the program to freeze. This article discusses detecting, fixing, and avoiding this bug pattern.
