It’s time for Apple to revive one of its discontinued iPad accessories

9to5mac.com Michael Burkhardt 2025-10-19 10:18:00

A few years ago, Apple used to have a much simpler iPad keyboard lineup. It just offered a Smart Keyboard for each of their iPad models, and they all essentially served as the same product. Nowadays, after the introduction of trackpad support in iPadOS and the Magic Keyboard, everything is unnecessarily convoluted – with each iPad model having a slightly different Magic Keyboard and varying features. While the keyboard lineup is a mess, that’s not what I take issue with right now – it’s the fac

Web Bot Auth is an authentication method that leverages cryptographic signatures in HTTP messages to verify that a request comes from an automated bot. Web Bot Auth is used as a verification method for verified bots and signed agents. It relies on two active IETF drafts: a directory draft ↗ allowing the crawler to share their public keys, and a protocol draft ↗ defining how these keys should be used to attach crawler's identity to HTTP requests.

Dell 14 Premium Review: Hello Old Friend

Dell is facing an uphill battle. It’s relaunching an already divisive laptop design with no significant changes. The new Dell 14 Premium retains the limited ports, touch-button function keys, and the invisible trackpad of its predecessor, none of which were particularly popular. Unfortunately, it doesn’t have the XPS pedigree to lean on. The axing of the XPS name was one of the many casualties in the company’s new, “simplified” brand.

On Linux, Control-C and Control-V don't work for copying and pasting in terminals. The Control modifier is used for its original purpose of inserting control codes. Instead, terminal apps require an extra Shift modifier, like Control+Shift+C. But what if there were hidden shortcut combos for copy and paste on Linux that work across most apps without adding any additional software or configuration? By the end of 2025, this will be the case, and many apps already support them. Here's the scoop!
