The advantages of virtualization are obvious for almost everyone. One of the first influential articles on the subject was my article [1] which was of interest to more than 48,000 readers. Below you will find useful and quick methodology on how to install and use Fedora 17 under the Windows 7 environment to gain efficiency and productivity in a cost-effective and convenient way. Only free tools will be used. PC used for this article has 6 GB of RAM and Intel core i7 CPU. The PC runs under 64-bit Windows 7 and has 680 Gb HDD. This is a typical PC configuration at the time of writing, so most of the readers have a PC with similar or better parameters and that's why the technology described above will be useful "out-of-the-box" without any additional investments. To mention the last but not the least pre-condition, it will be useful to have JDK 1.7 (from update 5 and u... (more)

The 'Best of Both Worlds': Running Fedora 8 on Legacy Windows XP

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 ... (more)

The Best of Both Worlds

These days the size of almost all the resources available to a programmer (memory volume, CPU speed, etc.) are on the rise except for one: the time required to complete a project, which is shrinking. So it's important to work with tools that are convenient and make you productive. It's also important to keep the cost of software development in check by keeping as much as possible of the investments that were already made. Windows - and currently XP Home and Professional are the most widespread versions - has a huge number of installed copies that can be measured in the hundreds ... (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)

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)
