An anaglyph or stereoscopic image is an image in which the illusion of depth is produced by offsetting two copies of the same image in two different colors. Anaglyphs are commonly known as “3D images” and are routinely used for entertainment, science, and medical purposes. How Anaglyphs Works Anaglyphs work by layering two separate copies of the same image so that the left eye sees one copy and the right eye sees the other. While the two images are layered on top of one another, they are always in different Read More

The most common viruses are boot sector infectors. You can help protect yourself against those by write protecting all disks which you do not need write access to. Definitely keep a set of write protected floppy system disks. If you get a virus, it will make things much simpler. And, they are good for coasters. Only kidding. Scan all incoming files with a recent copy of a good virus scanner. Among the best are F-Prot, Dr. Solomon’s Anti-virus Toolkit, and Thunderbyte Anti-Virus. AVP is also a good program.

Magnetic propulsion is the act of moving an object with magnetic fields and a flowing electrical current. The current is used to manipulate the system’s magnetic field or charge a fluid in the system that can be repelled. The Lorentz force then pushes the conductor in a direction that is perpendicular to the magnetic field and the conductor. The repulsing force is then used to propel the system, which is designed to take advantage of this effect. Governments and industries continue to invest significant time and money into the field Read More

In the world of art and animations, there are many different programs that the user can use in order to create realistic and detailed digital images. These programs often have limited functionality, however, and can only create 2D images. When the user wants to create a more artistic image, he/she needs software that is able to create 3D images. This article will list a number of such programs that are able to not only create 3D images, but also enhance the user's art by providing a number of additional features Read More

  PDF documents can utilize two passwords: Password to open Password to restrict printing and editing Password to Open The Password to open requires a user to enter a password to view the document. When the user sets a Password to open, all of the strings and streams in the PDF document are encrypted with the RC4 stream cipher. The Password to open is also know as the User password. Password to Restrict Printing and Editing The Password to restrict printing and editing can be configured to require a user Read More

A mobile firewall is a hardware and software system that is designed to protect wireless communication networks from unauthorized access and use. The whole system works when it is used connectively and if the mobile node, the firewall hardware and software system, and the network itself are present and operational. The mobile communications firewall system is made and designed to safeguard the network's system together with all of the mobile clients or subscribers that make use of the services offered by the network. The mobile firewall system acts as an Read More

Dots per inch is a measurement used for spatial printing and video dot density in which the number of dots that can be packed into a single inch of space is measured. While only related indirectly, the DPI value does tend to correlate with the resolution of a screen. DPI can be best seen when zooming in real close on something. The tiny dots are then visible to the naked eye. These tiny dots make up the images when looking at a printed picture or the screen. DPI in Video Read More

Most web browsers store web pages and images that we browse on the Internet. The web browsers cache (meaning, temporarily store) these files for a short time in your computer. If we revisit a pre-visited web page while these files are still in the cache, the web browser retrieves the files from the disk cache instead of getting these files from the web site. This can significantly speed up web browsing, but it may not render the updated web page in some cases. The web browser cache can cause privacy Read More

A clock generator is a type of circuit that produces a continuous, synchronized electrical signal for timing purposes in a wide variety of devices. Because many high end electronic equipment require that electrical signals and mechanical devices work together in an efficient manner, clock generators are often a necessary component in many devices in order to ensure that all other components work harmoniously.   How Clock Generators Work Clock generators are generally made of a quartz or ceramic piezo-electric circuit board that includes an oscillator and an amplifier. As the Read More

Wind energy is an alternative source of electricity. This technology harnesses the power of the wind. Specifically, the wind spins turbines which powers generators whose main task is to produce electricity. The wind is one of the safest and cleanest sources of renewable energy today. The concept is similar to those of windmills used for crushing grains or for irrigation. However, in the case of wind turbines, the force of the wind on the blades creates rotational motion; this motion is used to generate electricity. Wind is just a simple Read More
