FastCGI is a binary network protocol for connecting an application server to a web server. FastCGI is similar to the Common Gateway Interface (CGI), but is designed to circumvent its performance issues. Difference to CGI When a CGI-based website is accessed, the web server starts a process of the CGI program and terminates it at the end of the request. Because CGI programs … [Read more...]
What is Common Gateway Interface (CGI)
The Common Gateway Interface (CGI) is an interface for data exchange between a web server (application program) and third-party software that processes requests. CGI is a variant of making websites dynamic or interactive. The technology was developed at the National Center for Supercomputing Applications (NCSA) and has been used on the World Wide Web since 1993. How CGI … [Read more...]
Basics of Scripting Language
Scripting languages are programming languages that are executed through an interpreter. They sometimes dispense with language elements, the usefulness of which only comes into play when working on more complex tasks. In scripting languages, for example, the obligation to declare variables is usually dispensed with – advantageous for the quick creation of small programs, but a disadvantage for … [Read more...]
Importance of Learning Perl in Modern Computing
Perl is one of the general-purpose programming languages. In the ever-evolving landscape of programming languages, Perl, often dubbed the "Swiss Army chainsaw" of scripting languages, continues to hold its ground despite the emergence of newer languages. While it might not be as shiny and hyped as some of its counterparts, Perl remains a powerhouse in various domains of computing. In this article, … [Read more...]

Basics of Thermal Imaging Camera
A thermal imaging camera (also known as a thermographic, thermal, or infrared camera, or in the military, a thermal imaging device) is a device similar to a conventional camera, but it receives infrared radiation and, unlike a pyrometer, reproduces the IR radiation as an image of the object. The infrared radiation is in the wavelength range from approx. 0.7 μm to 1000 μm. However, thermal … [Read more...]
Arduino Hardware Serial Examples
Arduino microcontrollers are renowned for their versatility and ease of use in a wide range of projects, from simple blinking LED experiments to complex robotics applications. One of the key features that make Arduinos so powerful is their built-in hardware serial communication capabilities, which allow for seamless data transmission between the Arduino board and other devices such as computers, … [Read more...]
What is a Tracking Pixel?
In the digital realm, where information is key and data rules, tracking pixels emerge as a powerful yet often overlooked tool for gathering valuable insights into user behavior. These minuscule pieces of code, hidden within the depths of web pages and emails, serve a vital role in the world of digital marketing and analytics. Let's delve into what tracking pixels are, how they work, and why they … [Read more...]
Basics of Serial Communication
Serial data transmissions transmit digital data autonomously on one line (or on one pair of lines). In contrast, in parallel data transfers, data is transmitted synchronously over multiple lines. The fundamental difference is that you don't have to take into account runtime differences between different lines for serial transmissions, which allows for much higher clock speeds. The name serial … [Read more...]
How To Protect Your Computer From Ransomware
In an age where cyber threats are rampant, ransomware stands out as one of the most insidious and destructive forms of malware. Ransomware attacks encrypt your files and demand payment in exchange for decryption keys, holding your data hostage until you comply with the attacker's demands. To safeguard your digital fortress against this menacing threat, it's crucial to implement robust … [Read more...]
