Essential Tools: Version Control Systems, Konrad Hinsen, Konstantin Läufer, George K. Thiruvathukal
Konstantin Läufer
Did you ever wish you'd made a backup copy of a file before changing it? Or before applying a collaborator's modifications? Version control systems make this easier, and do a lot more.

Konstantin Läufer
Testing is an important part of application development. Hardware engineers, in particular, have a long established history of testing for the obvious reason that it's awfully hard to rebuild a microprocessor every time a bug pops up in the design stage--not to mention the enormous headaches such bugs generate on the software side.

Putting A Slug To Work, Konstantin Läufer, George K. Thiruvathukal, Ryohei Nishimura, Carlos Ramirez Martinez-Eiroa
Konstantin Läufer
In this article, the authors explore various uses of inexpensive embedded Linux devices such as the Linksys NSLU2 ("slug"). Embedded computing is a topic of growing interest. Although novel architectures such as cell processors, graphics processors (GPUs), and FPGAs are growing in popularity, conventional microproessor designs such as Intel's Xscale (ARM) and Atom pack a punch in a small footprint, not to mention being widely supported by commodity operating system and development tools. We're convinced that this entire space is a tool worth keeping in the scientific programmer's and software developer's toolchests.

This second installment picks up where Konrad Hinsen's article "The Promises of Functional Programming" from the July/August 2009 issue left off, covering static type inference and lazy evaluation in functional programming languages.
Plone And Content Management, George K. Thiruvathukal, Konstantin Läufer
Plone And Content Management, George K. Thiruvathukal, Konstantin Läufer
Konstantin Läufer
In this column, the authors look at Plone, which they feel is one of the best content management systems available today. Even better, it?s distributed under a free open-source license: the cost of getting started is only limited to the time you have available to set up the software on a server. Plone is written in Python and uses the Zope application server infrastructure; it runs on most modern operating systems. The authors have even set it up at Loyola University Chicago in the Department of Computer Science. Besides being two faculty members who rely on Plone to host all …
Guest Editor's Introduction: Cluster Computing, George K. Thiruvathukal
Guest Editor's Introduction: Cluster Computing, George K. Thiruvathukal
George K. Thiruvathukal
What is cluster computing? In a nutshell, it involves the use of a network of computing resources to provide a comparatively economical package with capabilities once reserved for supercomputers. In this issue, we look at certain applications of cluster computing to problem solving. As the Beowulf project and clustering revolution celebrate more than 10 years in existence, it's interesting to see what remains the same and what has changed. Let's look at a few aspects of the clustering revolution in more detail.

Java At Middle Age: Enabling Java For Computational Science, George K. Thiruvathukal
George K. Thiruvathukal
Not long after the Mosaic Web browser appeared and Netscape communications formed, Sun Microsystems launched Java in a way that will be forever known as a marketing success story. All across the US, there were many Java Day events. I still have my t-shirts as proof of having been there.
Gentoo Linux: The Next Generation Of Linux, George K. Thiruvathukal
Gentoo Linux: The Next Generation Of Linux, George K. Thiruvathukal
George K. Thiruvathukal
One of the reasons scientific programmers love Linux is its less-is-more philosophy. We can configure it to be anything from a desktop replacement with USB port support to a blade in a large SMP compute engine to a powerful Web server. Although Linux's market penetration in these various sectors remains to be seen, plenty of people are pumping resources into the Linux world. In this article, I?ll explain why Gentoo Linux (www.gentoolinux.org) is a good choice for scientists, and how its structure gives us the flexibility and ease of management we need.

Emerging technologies such as free and open source project hosting will hopefully broaden interest in scientific programming in a business context.

Home Networking, George K. Thiruvathukal
George K. Thiruvathukal
My coeditors (Paul Dubois and Konstantin Läufer) and I are among a growing number of individuals who install and maintain a home computer network. When Paul and I first discussed the idea of writing an article about the subject several months ago, my first thought was that you--our cherished readers-might consider this whole notion so trivial as to not be worthy of a column that focuses mostly on scientific programming and software development topics. But based on the realization that we three computer scientists devote a significant part of our time to network and system administration, it almost goes without …

Your Local Cloud-Enabled Library, George K. Thiruvathukal
George K. Thiruvathukal
Libraries are an important onramp for technology. They're known for making books accessible and have been pioneers in database access, but many branches seem to understand that they have a vital cultural role to play, especially when it comes to technology access. Most people in American society presume such access is ubiquitous, even though a substantial percentage of the world population lacks access.

George K. Thiruvathukal
In this installment of At Issue, two of CiSE's editorial board members describe the magazine's current and future Web presence. We start with Bill Feiereisen's discussion of science on the Web and what it could mean for CiSE ("Are We There Yet?") and end with George Thiruvathukal's discussion of the challenges therein ("If We Build It, Will They Come?"). CiSE's official homepage is www.computer.org/cise; we gladly welcome comments with suggestions or feedback. You can contact lead editor (Jenny Stout; jstout@computer.org) or write to either Bill or George (their email addresses appear at the end of their respective essays).
