How to install and Configure Smoothwall Express 3 Firewall

The SmoothWall GPL project was founded in the summer of 2000 by Lawrence Manning (Principle Code Author) and Richard Morrell (Project Manager). Their goal was to create a Linux distribution that could convert a redundant PC into a hardened internet firewall device. With help from other early contributors; John Faulty and Tom Ellils, the first SmoothWall Firewall was posted to sourceforge.net at the end of August 2000.

The project was immediately popular and grew rapidly. Within weeks, thousand of copies had been downloaded and SmoothWall was appearing regularly on magazine cover CDs in the UK and overseas. Many more developers joined the team and new versions were released almost weekly, incorporating new features based on software contributions from all round the world.

How to build XVM VirtualBox under Linux

VirtualBox is a general-purpose full virtualizer for x86 hardware. Targeted at server, desktop and embedded use, it is now the only professional-quality virtualization solution that is also Open Source Software.

How to build XVM VirtualBox in Windows

As VirtualBox is a cross platform project, we use a cross platform build system meaning that there won’t be any Visual C++ project files that you can open and just build. Instead, you have to follow these steps but they aren’t overly difficult.
Building VirtualBox on Windows 2000 should work fine except for one or two missing runtime DLLs that are required by tools or libraries in the VirtualBox build. It is very likely that these DLLs are already installed on your computer by some other program, so you might not even notice.

XVM VirtualBox – virtualization for the desktop

xVM VirtualBox enables desktop or laptop PCs running the Windows, Linux, Mac or Solaris operating systems to run multiple, different operating systems side-by-side, switching between them with just a click of the mouse. This allows software developers to more easily build multi-tier or cross-platform applications, or power-users to take advantage of applications that may not be available for their base operating system of choice.

What is IPTV?

What is Open Source?

Open source is a philosophy which suggests that the source code behind something should be freely available to the public. The principle originated in the software industry in the late 1990s, with several releases of open source software and operating systems, and it has since diffused into other communities as well. There are a number of strong arguments for releasing something in open source format, whether it be a recording, a software tool, or an entire operating system.

What is the Difference between Barcode and RFDI?

A barcode is a series of lines and numbers used to record information about an item. For example, a product bar code found in a supermarket on a can of chicken noodle soup might contain the manufacturer lot number for the can, which also tells the user when this can of soup was produced. It might also dictate the item code that tells the user which item has been selected. Barcodes can also include the price of the item, as would be the case for the chicken noodle soup, allowing the cash register to scan the barcode and record the price of the item. This also serves as an inventory tracking mechanism for the soup, when the item is scanned by the cashier, these units can be removed from inventory.

What is the Difference Between CDs and DVDs?

One of the first differences between CDs and DVDs to note is in the amount of data storage that is possible with each device. The typical DVD will provide in the range of seven times the capacity that is available on a compact disk. DVDs make use of a series of recording layers and also store data on both sides of the device, which makes a big difference in the storage capacity. The older technology associated with the CD does not allow for these same applications.
