What is Context Engineering? A few years ago, many, even top AI researchers, claimed that prompt engineering would be dead by now. Obviously, they were very wrong, and in fact, prompt engineering is now even more important than ever. It is so important that it is now being rebranded as context engineering. Yes, another fancy term to describe the important process of tuning the instructions and relevant context that an LLM needs to perform its tasks effectively. Much has been written already

Good questions. And as Monday came and went without any sign of the missing Mercedes, the mystery deepened, and more theories continued to pour in: had it been hotwired and moved to a chop shop? Was it used for a joy ride and ditched in some remote corner of the island? The family asked the Current to share a photo of the vehicle, and the fact that it had been reported stolen. The post set off a deluge of messages along the lines of: "Who steals a car on Nantucket? Where are they going to go?"

Speedballing—the practice of combining a stimulant like cocaine or methamphetamine with an opioid such as heroin or fentanyl—has evolved from a niche subculture to a widespread public health crisis. The practice stems from the early 1900s, when World War I soldiers were often treated with a combination of cocaine and morphine. Once associated with high-profile figures like John Belushi, River Phoenix and Chris Farley, this dangerous polysubstance use has become a leading cause of overdose death
