Autonomous powerline recharging revolutionizes drone operations
Researchers at the University of Southern Denmark have created an autonomous drone system for prolonged operations near powerlines. It lands on powerlines using advanced perception and recharges using a split-core current transformer. Tested outdoors, it showed hours of continuous operation, suggesting extended endurance potential. Future plans include improving robustness, expanding missions, and testing in various conditions.

RISC and CISC: Understanding the Differences and Their Impact on Computer Architecture
The history of computer architecture has been marked by two distinct design philosophies - Reduced Instruction Set Computing (RISC) and Complex Instruction Set Computing (CISC). The debate between these two architectures has been ongoing since the 1980s, and it remains relevant today as we continue to push the boundaries of computing power and efficiency. In this article, we will explore the differences between RISC and CISC, their respective advantages and disadvantages, and examples of their implementation.
What is RISC?
Reduced Instruction Set Computing (RISC) is a computer architecture that emphasizes a simple and efficient instruction set. RISC processors have a smaller instruction set than CISC processors, with each instruction performing a single operation. The goal of RISC architecture is to reduce the amount of work the processor needs to do for each instruction, which leads to faster and more efficient processing.

Microcontroller Architecture
There are two main types of architecture in computers: Von Neumann architecture and Harvard architecture.
Von Neumann architecture consists of a CPU, single-shared memory, an input unit, and an output unit. This type of architecture is associated with the Von Neumann bottleneck since the CPU and memory are separated. Therefore, the rate at which data and instructions get transferred in Von Neumann architecture depends on interconnectivity, which is one bus (an electrical connection that transfers information from memory to CPU). This type of architecture also allows the development of operating systems. Von Neumann architecture has been utilized in machines like personal computers, workstations, and laptops.
On the other hand, Harvard architecture consists of two separate memories, two address buses, two data buses, a CPU, an input unit, and an output unit. This model provides the solution to the Von Neumann bottleneck problem since it has two separate memory spaces. However, designing and developing the control unit in Harvard architecture is quite complex and expensive as compared to Von Neumann architecture. Despite this difference, none of the two architecture is considered superior to the other, and their suitability mostly depends on their applications. Harvard architecture has been utilized in machines like dataflow machines, enigma machines, microcontrollers, and quantum computers....

What is Endianness? Big-Endian vs Little-Endian
What is Endianness?
Different languages read their text in different orders. English reads from left to right, for example, while Arabic is read right to left.
This is exactly what endianness is for computers.
