Now’s a great time for Apple to bring back this long-removed iMac feature

9to5mac.com Michael Burkhardt 2025-10-25 15:46:00

A while ago, Apple used to include a software feature with macOS on older iMac models. It was called Target Display Mode, and it allowed you to turn an iMac into an external display once your iMac was too dated to be a usable computer. The company got rid of it with the introduction of the 5K iMac due to technical limitations at the time – though said limitations no longer pose a challenge. As mentioned, Apple previously got rid of the feature due to technical limitations. After the company int

Spacing Over Cards

news.ycombinator.com Unknown 2025-10-25 08:49:11

This post is a rationalisation of “I don’t like cards”. I say that in most cases where cards are used, they don’t need to be used. Specifically, they take space, they let you skip gestalt principles and be lazy and undisciplined, and being so easy to implement they are often used by developers. To multiply the effect, you can put a card into a card, and it seems so hard not to do so. We recognise patterns. This is known for quite some time, specifically Wertheimer in 1923 wrote the paper that e

Apple’s discontinued MagSafe Battery Pack doesn’t just stick to iPhones now

We all miss Apple’s MagSafe Battery Pack and want to see it return. In the meantime, the old magnetic battery accessory has resurfaced in an unlikely place. Apple introduced MagSafe as part of the iPhone 12 lineup, mainstreaming magnetically attached accessories and vastly improving wireless charging performance with precision alignment.

Why haven't quantum computers factored 21 yet?

news.ycombinator.com Craig Gidney 2025-10-25 12:14:26

In 2001, quantum computers factored the number 15. It’s now 2025, and quantum computers haven’t yet factored the number 21. It’s sometimes claimed this is proof there’s been no progress in quantum computers. But there’s actually a much more surprising reason 21 hasn’t been factored yet, which jumps out at you when contrasting the operations used to factor 15 and to factor 21. The circuit (the series of quantum logic gates) that was run to factor 15 can be seen in Figure 1b of “Experimental real

When oxygen was absent, RSW1 could process hydrogen gas and elemental sulfur—chemicals it would find spewing from a volcanic vent—and create hydrogen sulfide as a product.
