Write Code, Write Life

There is nothing in the world more amazing than the wonders of science and nature unfolding before us. The technology and the biological life we are surrounded by everyday are a proof to the fact that science is far more fascinating than any magical or fantasy tale we’ve encountered. So, here are some such incredible science facts that will take you on an irresistible trip to a world of wonder. 1. Ferrofluid – a suspension of magnetic nano-particles that form patterns of spikes in the presence of magnetic field.    Ferrofluid is a colloid made of magnetic nanoparticles suspended in a carrier fluid such as organic solvent or water. Ever single one of these particles are coated with a surfactant so that they won’t clump together into a lump and stay fluid. The formation of spikes is due to normal-field instability, an effect that causes the fluid to assume a shape that minimizes the total energy of the system. It was first invented as a liquid...

Over the 50 years or so that electronics circuit designers have been working on semiconductor-based logic circuits, many designs have been developed for creating logic gates. Because each approach to designing logic circuits results in an entire family of logic circuits for the various types of gates (NOT, AND, OR, NAND, NOR, XOR, and XNOR), the different designs are often referred to as design families. Here are the most popular:                             RTL: Resistor-Transistor Logic, which uses resistors and bipolar transistors. DTL: Diode-Transistor Logic, which is similar to RTL but adds a diode to each input circuit. TTL: Transistor-Transistor Logi c which uses two transistors, one configured to work as a switch and the other configured to work as an amplifier. The switching transistor is used in the input circuits, and the amplifier transistor is used in the output circuit...

Artificial Intelligence is a branch in computer science in which we train computer to behave like humans. The term was coined in 1956 by John McCarthy at the Massachusetts Institute of Technology.            Currently, no computers exhibit full artificial intelligence (that is, are able to simulate human behavior). The greatest advances have occurred in the field of games playing. The best computer chess programs are now capable of beating humans. In May, 1997, an IBM super-computer called Deep Blue defeated world chess champion Gary Kasparov in a chess match. An artificial intelligence system has accurately predicted when patients with heart conditions will die, according to new results published in the journal Radiology. The study was conducted by a team of scientists at the London Institute of Medical Services, who trained the software to analyze blood tests and intricate 3D models of beating hearts in order to detect si...

What is File Extension? A file extension, sometimes called a file suffix or a filename extension, is the character or group of characters after the period that make up an entire file name. The file extension helps an operating system, like Windows, determine which program on your computer the file is associated with. For example, the file myfile.docx ends in docx, a file extension that might be associated with Microsoft Word on your computer. When you attempt to open this file, Windows sees that the file ends in a DOCX extension, which it already knows should be opened with the Microsoft Word program. File extensions also often indicate the file type, or file format, of the file... but not always. Any file's extensions can be renamed but that won't convert the file to another format or change anything about the file other than this portion of its name. File Extensions vs File Formats File extensions and file formats are often spoken about interchangeably - I do it h...

What is a Virtual Private Network (VPN)? A VPN or Virtual Private Network is a network connection that enables you to create a secure connection over the public Internet to private networks at a remote location. With a VPN, all network traffic (data, voice, and video) goes through a secure virtual tunnel between the host device (client) and the VPN provider’s servers, and is encrypted. VPN technology uses a combination of features such as encryption, tunneling protocols, data encapsulation, and certified connections to provide you with a secure connection to private networks and to protect your identity. VPN connections technically give you all the benefits of a Local Area Network (LAN), which is similar to that found in many offices but without requiring a hard-wired connection. Early VPNs were often set up to give individual employees secure remote access to their company networks, hence the name “virtual private network”. By connecting to the company’s netwo...

Computer Virus Information.   What is a computer virus? Think of a biological virus – the kind that makes you sick. It’s persistently nasty, keeps you from functioning normally and often requires something powerful to get rid of it. A computer virus is very similar. Designed to relentlessly replicate, computer viruses infect your programs and files, alter the way your computer operates or stop it from working altogether. It’s estimated that the Conficker virus infected more than 10 million computers in 2009. Tens of thousands of computer viruses now operate over the Internet, and new computer viruses are discovered every day. How does a computer virus find me? Even if you’re careful you can pick up computer viruses through normal Web activities like: Sharing music, files or photos with other users Visiting an infected Web site Opening spam email or an email attachment Downloading free games, toolbars, media players and other system utilities Install...
