Finding the Exact 8:1 Gear Ratio The starting point of this project was figuring out how to achieve an exact 8:1 gear ratio with the capstan drives. In my capstan drive video, I designed all the drives to have an 8:1 gear ratio—but when measured, none of them actually did. The commenters on that video pretty accurately diagnosed my mistake. I had made the outer diameter of the big drum 8 times larger than the outer diameter of the small drum, but this doesn't account for the diameter of the rop

AirPods automatic switching supports CarPlay in iOS 26 Automatic switching is one of those ‘magic moment’ features that can make the Apple ecosystem so appealing.

Optimizations That Aren't

Optimizations that aren't We all like it when our code is fast. Some of us like the result, but dislike the process of optimization; others enjoy the process. However, optimization for the sake of optimization is wrong, unless you’re doing it in your pet project. Optimized code is sometimes less readable and, consequently, harder to understand and modify; because of that, optimization often introduces subtle bugs. Since optimization is not a process with only positive effects, in production it

TapTrap: Animation‑Driven Tapjacking on Android

TapTrap is a new type of attack targeting Android devices. It allows an app without any permissions to misuse screen animations. This app can secretly open another screen, such as a permission prompt, and make it invisible. The attack can then be used to trick you into performing sensitive actions, such as granting camera permissions or even erasing your device, without your consent. The idea is simple: imagine you’re using an app. While you use it, it opens another screen, such as a system pro

A new study published today in Current Biology challenges the popular conception that spiders first emerged on land, instead suggesting that these arachnids and their relatives originated and evolved in the ocean.
