The “sudo” command, short for “superuser do,” is a valuable tool in Unix and Linux systems, allowing users to execute programs with elevated privileges without needing full administrative access. It enhances system security by reducing the need for constant administrator login and creating detailed logs of commands used. Microsoft has introduced this functionality to Windows … Read more
In “Everyday Philosophy,” we explore how to handle a ruthless colleague without becoming similar ourselves. Machiavelli and Erikson provide insights. I once had a colleague, Aiden, who was ambitious and quick to move up the career ladder. His methods were questionable, leaving me feeling disloyal and distasteful. Machiavelli, author of “The Prince,” advocated for ruthlessness … Read more
The Standard Model of particle physics, which explains the fundamental building blocks of matter and their interactions, is known to be incomplete. Scientists are searching for signs of new physics phenomena to guide them towards a more comprehensive theory. At the recent ICHEP conference, the ATLAS collaboration presented its first results from searches for new … Read more
Charged particles emit radiation when moving faster than the light phase speed in a medium, which forms a cone-shaped pattern, known as the Cherenkov effect. This phenomenon was awarded the Nobel Prize in Physics in 1958 for its fundamental and practical applications. The oblique incidence of light on an interface between two media results in … Read more
Personal finance experts usually advise against buying unnecessary items while paying off debt. However, the author argues against this approach and shares her own spending rule called the “$1 rule.” This rule involves determining how many times you’ll use an item before buying it and only purchasing if the cost per use is $1 or … Read more
Researchers at the University of Liège have used Raman spectroscopy to determine the acidity of ionic liquids for the first time, outperforming traditional methods. This discovery is significant as ionic liquids contain more active protons due to lower proton solvation, making them much more acidic than water. Ionic liquids are composed of organic salts and … Read more
Here is a rewritten version of the text in simpler language: Uncertain Selves and the Quantum-Like Fabric of Awareness Every thought, every decision, and every observation creates something new. This idea can help us understand our minds. Thread One: The Observer Effect When we look at words or symbols, they take on meaning. Our perception … Read more
Warren Buffett’s decision to leave his fortune to a trust controlled by his children instead of the Gates Foundation will have negative consequences for the world. Buffett had planned to give away his estimated $137 billion fortune to the Gates Foundation after his death, but now it will be divided among his three adult children. … Read more
A new study suggests that the Step Pyramid of Djoser in Egypt was built using a hydraulic lift around 4,500 years ago. This would be earlier than previously thought for major hydraulic systems. The pyramid’s design, waterways, and interior architecture all point to the use of a hydraulic system. The study, published in PLOS ONE, … Read more
What a fascinating article! Tycho Brahe, an astronomer and alchemist, was a true Renaissance man. His discovery of a supernova in 1572 led to his appointment as the royal astronomer for King Frederick II of Denmark and Norway, which enabled him to build his observatory on the island of Ven. The article highlights the surprising … Read more
