In this post we will introduce how to install MiKTeX plus TeXstudio on windows. This is very easy! You simply have to accept just about all the default settings. Step 1: To begin with you have to go to the MikTeX website and navigate at the downloading page. From there you could pick the appropriate installer (32bits or 64bits) based on your system. [ Link ] Step 2: Just start the installation process and accept…

An obfuscation technique (also called Polymorphism) is a way of constructing a malware that make it more difficult to detect. If a malware is hard to detect, it is likely to spread more widely. The following are commonly used obfuscation techniques: Self-Encryption and Self-Decryption. Some viruses can encrypt and decrypt their virus code bodies, concealing them from direct examination. Viruses that employ encryption might use multiple layers of encryption or randomcryptographic keys, which make each instance of the…

Markdown, originally written as a Perl script by John Gruber and Aaron Swartz in 2004, has caught fire and the technology has exploded into many different forms of “text to HTML” markup engines. The original Markdown code has largely been unchanged through the years, while alternative versions have come to build on it. Since the creators of Markdown don’t want anybody using the “Markdown” name, each fork of the project adopts another name, which gets confusing.…

In this post i will present you my first double sided custom pcb made using a simple but “effective” CNC 3020. I’m a CNC newb so my milling process, and the following outline uses what I’ve concluded to be the most common tools. These tools are Eagle CAD, PCB-gcode, Mach 3 CNC, 0.1mm 30deg V-Shaped Engraving Bit, and of course random surplus carbide PCB drill bits from Amazon and several other online markets. I have to say…

What Is Inverse Kinematics? Kinematics is the science of motion. In a two-joint robotic arm, given the angles of the joints, the kinematics equations give the location of the tip of the arm. Inverse kinematics refers to the reverse process. Given a desired location for the tip of the robotic arm, what should the angles of the joints be so as to locate the tip of the arm at the desired location. There is usually…

Two undergraduate students at the University of Washington have created a pair of smart gloves that can translate American Sign Language (ASL) automatically into text or speech. Designed to help bridge the communication gap between the Deaf and hearing communities, the SignAloud gloves use sophisticated sensors to recognize ASL gestures. They were recently awarded a $10,000 Lemelson-MIT Student Prize for their work. The inventors, Navid Azodi and Thomas Pryor, created the SignAloud glove prototype in…
