One of the beauties of Linux from a business point of view is that it doesn’t require the “latest and greatest” hardware to run properly. This means you can increase the return on investments (ROI) for legacy hardware. As I’ll show in this article, as in the case with virtualization, the “latest and greatest” software is not required either. Consider the following example. Back in 2005 I purchased (as did many other businesses) a P4 3.4 GHz laptop with 1 GB RAM and 120 GB hard disc drive (HDD) under Windows XP Pro SP2 (throughout the article I will refer to it as Windows XP for brevity’s sake). Now it looks like a message from the stone age, but back then it was a decent PC. The virtualization software that I used was VMWare Workstation 5 (aka VMWare 5). Virtual machines (VM) with various Linux/Unix distributions were placed... (more)

Running Fedora Core 5 Under Windows XP - Tips and Tricks

For one thing XP is extremely widespread and your clients and/or users probably have it installed on theirs PCs. In fact, most PCs come with XP pre-installed. And makers of peripheral devices and high-speed Internet providers adapt their products and services to work with XP. In most cases it's enough to simply plug a peripheral into an XP computer or to subscribe to a high-speed Internet service to start use it immediately. For many IT professionals it makes sense to work with both Windows XP and Linux. On the other hand, Linux is stable and the Linux community provides you with... (more)

Migration of Legacy Scientific and Engineering Applications

There is a market from which a history of computers began - a market of numerical simulations for scientific and engineering applications. Note that these applications usually deal with a high number of mathematical calculations that are impossible without a computer. Historically, this was what provoked the computer's invention. Also, the main purpose of software for this market is to provide results in a reasonable amount of time. Despite a long history, this market is alive and well, and it will be for the foreseeable future. Consider, for instance, the following fields of num... (more)

Using Ext JS, Servlets, JSON, MySQL and Tomcat on Fedora

Java Developer Magazine on Ulitzer These days the popularity of Ext JS (a JavaScript library) is gaining momentum. One of the most popular widgets within Ext JS is the DataGrid. The reason - displaying data from a database is one of the most common tasks of a web application. "Out of the box" the DataGrid has functionality (for instance, ascending or descending sorting and reordering of columns by dragging it) that otherwise would require some effort from developers. Another attractive feature of the DataGrid is that it can use JSON (JavaScript Object Notation), which allows you... (more)

Remote Benchmarking with Servlets and JSF

Powerful computers these days (including servers) are cheap compared to the "good old days." In fact, they're even cheap compared to what they cost a couple of years ago. Vendors are selling PCs whose CPUs clock above 3GHz for under $1,400. Their memory and HDD capacity are also impressive. We're basically looking at hardware that can potentially offer the performance of a mainframe for a fraction of a mainframe's price. The operative word is potentially. A gating factor is the set of software- and hardware-related components that sits between a CPU's clock speed and the end use... (more)
