Inside Memory Management

Eugenia Loli 2004-11-18 General Development 5 Comments

Memory management is one of the most fundamental areas of computer programming. In many scripting languages, you don't have to worry about how memory is managed, but that doesn't make memory management any less important. Knowing the abilities and limitations of your memory manager is critical for effective programming. Get an overview of the memory management techniques that are available to Linux programmers, focusing on the C language but applicable to other languages as well.

Take a good look at your Heap

Regarding Gambas

Guest post by Daniel Campos Fernández 2004-11-11 General Development 48 Comments

For a few years, I've been working in the real world, I mean the enterprise world, sorry. In every company I've worked for, they offered me the opportunity to learn a lot of new things, or at least that's what they always said in the first meeting before sending me to be just another company programmer. But in fact I've learned some very important things, just not about programming. I had to learn about these things on my own, about the needs of a real company in the real world.

Imperfect C++: Functors and Ranges

Eugenia Loli 2004-11-08 General Development 9 Comments

In most cases, functors and ranges cause a minor issue of too many keystrokes, but in some cases, they can cause a serious impediment to maintainability. This chapter will teach you to deal with this problem while it's still a minor one.

Introduction to Unicode

Eugenia Loli 2004-11-01 General Development 33 Comments

Unicode, or the Universal Character Set (UCS), was developed to end once and for all the problems associated with the abundance of character sets used for writing text in different languages. It is a single character set whose goal is to be a superset of all others used before, and to contain every character used in writing any language (including many dead languages) as well as other symbols used in mathematics and engineering. Any charset can be losslessly converted to Unicode, as we'll see.

Genetic algorithms simulate a Multi-Celled Organism

Eugenia Loli 2004-10-26 General Development 12 Comments

Create life, or something like it. 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. This article covers instructions on how to simulate a multi-celled organism.

Applying Wart-B-Gone to XML’s Imperfections

Submitted by Esther Schindler 2004-10-23 General Development 12 Comments

The experts at the Applied XML DevCon last week didn't just show off shiny new features (though they did get a preview of the XML capabilities built into Whidbey). They honestly discussed the flaws in XML technologies and what has to be done to address them.

Optimize Perl

Eugenia Loli 2004-10-22 General Development 7 Comments

Perl is an incredibly flexible language, but its ease of use can lead to some sloppy and lazy programming habits. We're all guilty of them, but there are some quick steps you can take to improve the performance of your Perl applications. This article looks at the key areas of optimization, which solutions work and which don't, and how to continue to build and extend your applications with optimization and speed in mind.

Build Grid Portals with Grid Portal Toolkit 3

Adam Scheinberg 2004-10-21 General Development No Comments

The Grid Portal Toolkit (GridPort) is a toolkit for developing Web-based portals and applications on top of an underlying distributed and grid computing infrastructure. GridPort aggregates grid services from grid software packages and provides additional grid capabilities while presenting a simple, consistent API for portal and application developers. This article presents an introduction to Grid Portal Toolkit 3, including the design philosophy, architecture, and capabilities of each component.
