A current look at the field of bioinformatics will reveal that it is a field that is largely dominated by the Linux operating system, as well as by programming languages such as Perl, Python, and Java. Windows and its associated native application development platforms are not in widespread use among present-day bioinformatics practitioners. In fact, the usage of Linux and other open source technologies will likely remain the dominant platforms upon which most novel and/or large-scale bioinformatics research is conducted. Scientific computing of all types has deep-seated roots in Unix and its derivatives, and as a result is very much dependent on code bases that are written with *nix platforms in mind. Many scientific applications are written for High Performance Comput... (more)

Why 'LiveCD' Should Be a Part of Every Computer User's Vocabulary

Throughout the last decade, society has witnessed an explosion of network connectivity among PCs and mobile devices as well as a vast proliferation of networked applications, ranging from Web-based email to online banking. The end result of this is that network connectivity has become an almost indispensable resource for many individuals. Yet along with the convenience and flexibility of... (more)

The Open Source Advantage in Secure Application Development

The security benefits and risks of Open Source code is one of the most debated topics in information security today. The views of proponents of the Open Source model are typified by Eric Raymond's argument that Open Source software is intrinsically more secure since its open nature lets a greater number of programmers view the source code and uncover potential security threats before the...

Windows for Supercomputers

In late May 2004, Microsoft made the announcement that it was considering entering the High-Performance Computing (HPC) Market, a market that has traditionally been dominated by custom-engineered Unix-based machines. In recent years, advances in technology have made possible the construction of lower-cost computing clusters that utilize off-the-shelf hardware such as Intel- and AMD-based... (more)

Demystifying Regular Expressions

The ability to perform pattern-matching operations on text is a skill that is highly useful to any programmer. Whether you are creating a routine to validate data entered into a form, performing parsing and mining on data sets, or searching for sequence similarities in the human genome, chances are that the ability to construct a regular expression will be of great value to you. A single... (more)
