The art of encryption, or the process of converting plaintext into ciphertext to protect it from unauthorized access, has been around for thousands of years. One of the earliest known methods of encryption is the scytale, a device used by the ancient Greeks to secure their messages. The scytale was...
Data storage is an essential component of modern computing, and the history of data storage is a long and fascinating one. The IBM RAMAC 35, introduced in 1956, was a landmark in the history of data storage and played a significant role in the development of modern storage technology. Before...
Hexadecimal, commonly abbreviated as “hex,” is a numerical system that is widely used in computer science and programming. It is a base-16 system, meaning that it uses 16 distinct symbols to represent numbers, as opposed to the base-10 decimal system that uses ten symbols (0-9). In this article, we will...
Braille is a tactile writing system used by people who are blind or visually impaired to read and write. It was developed by Louis Braille in 1824, and is based on a series of raised dots that are arranged in patterns to represent letters, numbers, and punctuation marks. Braille is...

Have you ever looked at a cloud and seen the shape of a dragon or a face? Or perhaps you noticed a pattern in a piece of toast that looked like a famous painting? These are just a few examples of pareidolia, a phenomenon in which the human brain perceives...
The D-Wave quantum chip is a revolutionary technology that has the potential to change the face of computing as we know it. Developed by D-Wave Systems, a Canadian quantum computing company, the D-Wave quantum chip is the world’s first commercial quantum computer. Unlike traditional computers that use binary bits to...
The history of computing dates back centuries, and many pioneers have made significant contributions to the field. Two such individuals are John Napier and Wilhelm Schickard, who were instrumental in the development of early computing devices. John Napier, a Scottish mathematician, is best known for inventing logarithms, a mathematical concept...
The Electronic Numerical Integrator and Computer, or ENIAC, was one of the first electronic digital computers, and it was a milestone in the history of computing. ENIAC was developed during World War II to help the United States Army calculate artillery firing tables. It was an enormous machine, covering 1,800...
