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)

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)

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)

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)
