This follows the addition of Apple Watch Ultra 2 in Black and M4 Max/M3 Ultra Mac Studio earlier this week. Apple Refurbished Macs are held to a very high quality standard, and more or less look brand new – minus the packaging. All essential components are replaced as part of Apples Refurb program.

Implementing Logic Programming

news.ycombinator.com Sir Whinesalot 2025-09-22 12:32:21

Most of my readers are probably familiar with procedural programming, object-oriented programming (OOP), and functional programming (FP). The majority of top programming languages on all of the language popularity charts (like TIOBE) support all three to some extent. Even if a programmer avoided one or more of those three paradigms like the plague, they’re likely at least aware of them and what they’re about. Or they’re applying one of the paradigms while denying that they’re doing so, like Has

Apple has officially added the iPhone XS to its list of vintage products, marking the end of an era for one of the more iterative chapters in the iPhone’s history.

As Trump Comes for Your Social Media, It’s Time You Consider What’s Worth Sharing

gizmodo.com Kyle Barr 2025-09-22 18:11:22

Agents of the Trump administration are increasingly using social media posts to crack down on immigrants, tourists, and even some U.S. citizens. Last month, a leaked document showed the State Department had crafted a new standard for reviewing the social media accounts of any foreign students planning to attend or even visit Harvard University.

Fans can argue day and night about Lucasfilm president Kathleen Kennedy but there’s no denying she pulled an awesome move earlier this week. As previously reported, the British Film Institute had been advertising that it would be screening a very rare print of George Lucas’ Star Wars from its original theatrical run. It’s the version of the film you can basically never see anymore, at least not officially, so Kennedy showed up at the event to change that. “I’m here to make sure you don’t think
